The invention concerns a connecting device for connecting the hinged part, in particular the guide part of a plow, to the side element section of chute mining devices that are located on the lateral element of the first overhead portion, located on the hinged side, and Rethimno connected with miscellaneous pieces the return false part, and at least one safety element, which in the closed position prevents the separation of the invoice parts and return the invoice, and in the open position allows the separation. The invention also concerns a section of the gutter, equipped with a detachable hinged part, in particular, the detachable guide machines for production of devices for the extraction of minerals, and hinged part via the connecting device, which has miscellaneous parts on the sections of the chute, the return false part on the suspended part and at least one safety element, which in the closed position prevents the separation of the invoice parts and return the invoice part, can Rethimno be attached to sections of the gutter. The invention also concerns the hinged parts for the sections of the chute or the corresponding connector on the device.

In underground mining devices, for example, for coal mining, applied production is down, which perform the reciprocating movement along the device for transporting mined coal. This kind of mining devices, which can be up to 400 m, in particular the plow units, respectively, on the face ends are special gutters to create the necessary structural space, allowing not only to enter the plane in the tail part of the lava, but also to have at the end of the lava actuators for plow. Appropriate special gutters can, in particular, consist of so-called wedge-shaped grooves, in which the distance from the sending machine to the side of the element along the length of the section of the trench increases, and consist of connecting grooves, in which the distance from the upper branch to the lower branch is increased, allowing then to circle the chain around the sprockets. In particular, these special chutes are used guides of the machine, which can detach from the section of the gutter, allowing mounting of the plow, the dismantling of a plane or repair the plane, replacing the support shoes Struga and perform other maintenance work of the plow. The detachable connection between the guide part of the machine and the section of gutter is carried out by means of connecting devices, including bill part and otveta the invoice part, which can be fixed at least with one safety element. The basic scope of the present invention are the corresponding wedge-shaped groove and the connecting trench with detachable guides of the machine as the hinged side sections of the gutter. There is, however, possible in principle of the invention and other mounted parts that need to detach from a section of the gutter.

This kind of connecting device is known from DE 20 2004 001 476 U1 and it is a known connecting device includes, among other things hook elements located in the lower area of the side elements, which dismantled the steering of the machine is inserted through the mounting elements, so that in the lower pane split occurs Kruchkova connection. The safety element such connecting devices should only prevent the divergence of the hinged portion and the side element with each other, for which the safety element is made either in the form of spin-on kick-plates, either in the form of a half-moon shaped cladding elements, which are bent forward over the side and in turn protected against separation by means of threaded pins. Thanks to the use of hook soy is inane can, however, to facilitate the installation guide of the machine. However, disconnecting, in particular, threaded the fingers is difficult, time consuming, and may, in particular, significantly complicated when jamming fingers, cladding elements or safety straps.

The objective of the invention is to provide a mounting device, as well as sections of the gutter and the hinged part, in which case quick and easy removal of the hinged parts.

This problem is solved in the connecting device in accordance with the invention through the fact that the safety element is aligned with the hydraulic cylinder to move the safety element between the closed and open position. Thanks used in accordance with the invention, the hydraulic cylinder for actuation of the safety element in the selection of appropriate hydraulic cylinders even the most stubborn of the safety element can be easily moved from the closed to the open position (and Vice versa), and, in particular, are given the opportunity to provide hydraulic pressure for the hydraulic load of the hydraulic cylinder with the hydraulic system of the lava. The invention solution, in particular a hydraulic cylinder, may amend the change miners almost without tools, as necessary solely to ensure that the hydraulic pressure of the hydraulic cylinder. This may be sufficient, as will be explained hereinafter, to connect the hydraulic cylinder to the existing hydraulic system of the lava, if necessary, only for a short time.

In particular, in one of the preferred embodiments of the invention, there are two safety element, and each safety element respectively aligned with one hydraulic cylinder. Using two safety elements in two spaced apart positions may be blocking miscellaneous parts and return miscellaneous parts from separation, so that the hinged part and section of trench with minimal cost is securely fixed against any movement relative to each other. Particularly preferably, when each of the two hydraulic cylinders provided United with the appropriate safety element is retractable and retractable piston rod, preferably a hydraulic cylinder provided with a piston rod lying on the same axis, and mirror are located on the lateral element of the sections of the chute so that the distance between the locking elements in the closed position is greater than in the open position the AI. In particular, with this arrangement, the piston rods of the hydraulic cylinders, and when otherwise positioned hydraulic cylinders with piston rods preferably, when both hydraulic cylinders have one thing in common hydraulic connection for movement of the extension and one common hydraulic connection for the movement of the retracting piston rods. Then to detach or fixing the mounting device to the miner is only necessary, for example, to connect the hydraulic system of the lava to the right hydraulic connection to move the hydraulic cylinder so that the safety element has been accordingly in the desired position.

In addition, preferably each invoice the part and return the invoice part provided at a distance interval over each other, the first and second (in assembled condition included in each other) by means of locking or geometric circuit and the protective element can accordingly be vdvinut'sā in this period or to run from it. In particular, the lower geometric means of the circuit could also be formed Kruchkova connection, as is known from the prior art. Top miscellaneous parts and the return false part would then consist of the of contiguous strips or the like, provided with grooves, in which in assembled position retracts the safety element. Alternative counter-miscellaneous parts could be made in the form of U. of items that can be hung in the slots on the overhead parts, preferably both the upper and lower slips and the return false part are composed of pairs of U. elements and grooves, as this type of implementation requires a relatively small structural space.

In one particularly preferred embodiments miscellaneous part could consist of C-shaped profile parts with integral shelves and rigidly connecting the end of the shelf cross-shelf and cross-shelf made transverse hole for receiving the centering element for centering and connecting successive sections of the gutter. The centering elements are used, in particular, when the detachable hinged parts, which are preferably provided with corresponding receiving elements for bonding elements for receiving the connecting pin elements, not yet mounted or not dismantled, in order to avoid the risk of pull-out sections of the gutter from each other when disassembled the guide parts of a plane.

In addition, predpochtitelno, when the safety elements movably attached to the guide elements, which are fixed on the lateral element, in particular welded. Through the interaction of the guide element and the piston rod by using relatively simple means may be provided for reliable maintenance of the safety elements parallel to the side sections of the gutter without any risk that guides the relief items will be removed by briquetting of fine coal or other Miscellaneous parts and the return false part may, in particular, consist of several bars, several inches long, which provide a hinged mounting hinged parts on the lateral element. As mentioned above, the overhead portion and the return false part can in the lower pane hook connection and the upper area consists of spaced parallel locking bars. It is advantageous if the protective elements can be moved parallel to the lateral element and/or in the horizontal direction.

The above task in the invention section of the gutter is solved due to the fact that the connecting device is provided consistent with safety element, using as controvery side element of the hydraulic cylinder and for moving the safety element between the open and closed position, in which the safety element prevents the separation of the invoice parts and return the invoice part. The connecting device may, in particular, possess the above characteristics, providing these benefits. Hinged part, in particular guide the machine may consist of guide parts of a plane, in particular of the guide parts of the plane for or wedge-shaped connecting grooves in the tail area of the mining device.

In accordance with the invention is used with such a connecting device or the corresponding section of the chute hinged part can be performed, in particular, in the form of a guide part of the plane and between the return miscellaneous parts may be provided with a removable stop plate serving to release the hydraulic connections for the actuation of hydraulic cylinders connecting device when removing this locking plate. In the proposed invention the hinged parts are, therefore, only the return false part, and a protective overlay hydraulic cylinder and hydraulic connections on the side section of the chute, so that the hydraulic cylinders are protected when mounted guide plane being between the rear wall of the guide part of the plane and the lateral element is ecchi gutters.

Other advantages and embodiments of the invention the connecting device become clear from the subsequent description of the embodiment, the section of gutter with a corresponding connecting device, and mounted or mounted on it guiding the plow. In the drawings shown:

Three shows of the gutter 1, 2, 3 form thus a transitional region or end region consisting of a set of standard gutters 1, laid in the longwall conveyor chute with attached guide plane, and there may be several wedge-shaped grooves 2, before tape-chain conveyor through a connecting groove 3 will be connected to the frame of the machine. On the connecting chute 3 can be mounted, as is well-known specialist in underground mining operations, for example, on the mounting of the console 5, the end stop of the plane to the mining plough could not damage the drive motors of the mining device. The basic scope of the present invention is a wedge-shaped groove 2, and attached thereto a connecting chute 3, which (both), respectively, supplied, performed here in a different way guide part 6 or 7 of the plow, which forms a detachable hinged portion and attached to suitable the section 8 wedge-shaped trough 2 or section 9 of the connecting chute 3 as a detachable hinged part. How, in particular, is well seen in figure 1, the guide elements are on both the guide portions 6, 7 of a plane with a small angle of inclination of the sections 8, 9 of the chute, which guides part 6, 7 plough made the type of a wedge-shaped grooves. Guide part 6 has a viewing plane of the flap to the top chain of the chain link of a plane, which is missing from the guide part 7 of the plow.

The invention is concerned primarily with a device for the detachable fastening of the guide parts 6, 7 of the plow to the relevant sections 8 or 9 of the gutter, and this connecting device, except dismantled and belonging guide parts 6, 7 of the plane of the locking plates 11, 12, is shown in figure 1 the image is not shown. For descriptions of the connecting device should refer to figure 2-7 on which the invention connecting device is illustrated on the example of the implementation of the V-gutter 2. Figure 2 shows the exploded view with the spatially separated parts of section 8 of the wedge-shaped trough 2 when disconnected guide part 6 of the machine. All connecting device 10 for detachable mounting of the guide part 6 of the plow section 8 of the trough is between composed, as appropriate, of several parts, located on the side of treatment is Aboa side element 13 section 8 of the gutter, also located on the side tabs of the rear wall 14 on the suspended portion 6. For detachable mounting to the side element 13 preferably welded or screwed two, respectively, indicated in General position 20 miscellaneous parts. Each invoice portion 20 communicates with a return invoice part 30 fixed to the rear wall 14 of the guide part 6 Struga, in particular welded. As already clearly seen in figure 2, the return false part 30 of the guide part 6 of a plow provided here two located one above another with an offset height of line elements 31, 32, through which the guide portion 6 of the plow can be hung in razoobrazny reception elements or, respectively, the grooves 21 and 22 on miscellaneous parts 20 on the section of the gutter. Miscellaneous part 20 and the return false part 30 respectively located near opposite ends 8A or 8B of section 8 of the gutter, and the back-wall portion 30, respectively, are located at the ends of the guide part 6 of the plow. Guide part 6 of the plow has already known the way the bottom path 15 of the machine, the lower open side stope chain channel 16A, the upper closed side stope chain channel 16B, the lower guide beam 17A and the upper guide bar 17B, which moves the sliding plane. Dscipline adjacent grooves to each other on the guide part 6 of the machine provides pockets 18 for coupling elements, when mounted gutters can be inserted and fixed power coupling elements 19.

Figure 3 is particularly clearly visible enforcement response miscellaneous parts 30 on the rear wall 14 of the guide part 6 of the plow. Located on a lateral distance from each other, the upper hook elements 31 are mirrored relative to each other and provided with a protruding down SitePlayer rib 33, which ends respectively to the center of the guide part 6 of the machine in acting even further down the stop 34. The lower hook elements 32 are supplied in turn serving down U-shaped hook plate 35, and the upper side of the lower U. elements 32 is formed by widening out towards the ends of the guide parts 6 plane bevel 36. Between the top line elements 31 and the beveled surface 36 on the lower U. the elements 32 is formed a relatively large gap or free space 37 for insertion, as will be explained, in a partial region of the gap 37 of the safety element for fixing the reply slip portion 30, and a removable part (20, Fig. 2). This will be explained with reference to four other pieces.

Figure 4 shows a side view of a section of gutter on the view side element 13, on which hung interacting with the response overlaid frequent the mi miscellaneous part 20. Miscellaneous part 20 also have the same design, however, are located mirror-symmetrically and each invoice part 20 is composed here of the C-shaped profile part with parallel upper limit shelf 23 and the lower end of the rack 24, which are connected vertically oriented transverse shelf 25. The upper end of the shelf 23 is supplied as, in particular, can be seen in figure 2, 5 and 6, the groove 21 whose width corresponds to the width of SitePlayer ribs 33 on the top U. the elements 31 response miscellaneous parts 30. The lower end of the shelf 24 of the profile is provided on the upper side in turn groove 22 whose width corresponds to the width of the hook strips 35 on the lower U. the elements 32 response miscellaneous parts 30. Match the width of the grooves 21, 22 in the end the shelves 23, 24 and included in these shelves flush U. strips 33, 35 top U. elements 31 and the lower U. elements 32 is particularly clearly seen in figure 5 and 6, which shows the section 8 of the gutter and the guide portion 6 of the machine in assembled position when both of them are connected to each other through the connecting device. While figure 5 shows also that the fixation between the line elements 31, 32 response miscellaneous parts and grooves 21, 22 in the end the shelves 23, 24 hinged parts, the farm is highlighted by having the form of a goose neck relief elements 40, which can move shown in figure 5 between the closed position shown, for example, in figure 2 the open position is preferably parallel to the conveying direction. Safety elements 40 are lower, here rectangular in cross section, the retaining shelf 41, which in the closed position, is pushed flush between the beveled surface 36 on the upper side of the lower hook element 32 and the bottom side 26 of the upper end of the shelf 23 and therefore also fills with geometric circuit between line elements 31, 32 or, respectively, end shelves 23, 24 miscellaneous parts or, respectively, the response of miscellaneous parts. If the safety element 40 with the retainer shelf 41 is in the closed position, forming the return false part of the hook elements 32, 33 are not able to move upwards, so that the overhead portion and the return false part can't get out of gear, and due to the cross-sections of the locking element 41, U. elements 31, 32 and grooves 21, 22 or respectively the end of the shelves 23, 24 can be prevented the formation of any gap for movement even at high efforts that occur during mining operations. In this case, as is clear to the specialist in the conveying direction of the thrust lugs 34 on vernacular elements 31 prevents any movement between section 8 of the groove and the guide part 6 of a plane.

Figure 4 shows the safety elements 40 in the open position. Figure 4 clearly shows that for both arranged with a lateral offset relative to each other Misc. parts 20 or, respectively, the response miscellaneous parts provided respectively on one of the safety element 40, and in the open position, as shown in figure 4, the distance between the two safety elements 40 less than in the closed position, in which both the safety element 40 is displaced outwards. In accordance with the invention the movement of the safety element 40, respectively, through co-ordinated with each safety element 40 of the hydraulic cylinder 45 which, as shown in figure 5, respectively provided with a piston rod 46 which is pivotally connected with the safety element 40 via pin 47 or staples or the like, Both the hydraulic cylinder 45 for both moved in opposite directions of the safety elements 40 are mirrored relative to each other so that the left hydraulic cylinder 45 during movement of the extension moves the piston rod and however left the safety element 40 to the left and the right hydraulic cylinder 45 to the right of the safety element 40 right. When retracting movement occurs with therefore, its reverse movement of the safety element 40. Piston rods of both hydraulic cylinders 45 lie on the same axis, so that efforts at promotion of the piston rods of the hydraulic cylinders may be supported relative to each other.

Both the hydraulic cylinder 45 can with both sides not shown, the piston surface of the piston rod to be fed with hydraulic fluid and, in particular, can be made in the form of a hydraulic cylinder with a floating piston. Hydraulic input 48 of both hydraulic cylinders 45 for extension of the piston rod is located near the colliding here with each other covers hydraulic cylinder 45, and the hydraulic inlet 49 for reverse movement of the piston rod and together with the protective elements 40 in the open position is located near opposite ends of both of the hydraulic cylinders 45. Both hydraulic input 48 connected by hoses 51 with a common hydraulic connection 52 to the load pressure for movement of the extension, and both hydraulic inlet 49 other hoses 51' is connected to the second hydraulic connection 53 to the retracting movement of the safety element 40. When the movement of both extension of the hydraulic cylinder 45 are guided by their caps into each other. When the movement of the retracting both of the hydraulic cylinders 45 are guided by the pins 55 on having here U is the image of the second form of the mounting block 56.

Now, if you want to disconnect the hinged part 6, you must first disconnect shown in figure 2, the stop plate 11, which is mounted between the two response miscellaneous parts 30 on the guide part 6 of the plow to loosen the two hydraulic connections 52, 53. Then one of the two hydraulic connections, for example a hydraulic connection 53 for moving the safety element 40 in the open position, connected to a hydraulic power source, such as a hydraulic system of lava, to provide the movement of the piston rods of the hydraulic cylinders 45 and move the safety elements 40 in the open position. As in underground longwall available high hydraulic pressure, the safety elements 40 can be moved even when they are with high stress were among the miscellaneous parts and return miscellaneous parts. Miners, in principle, requires no tools, only the connecting hose between the hydraulic connection 53 and the hydraulic system of lava. When the safety elements 40 are in the open position, the hinged part can be removed from the mounted position and can be completed maintenance work, for example, on one of pridvinutyh at the end of the second region lava mining planes off the guide part of the plane. Then the guide portion (6, 2) plow their response miscellaneous parts can be hung on the overhead part 20 and by hydraulic loading hydraulic connection 52 of the safety elements 40 respectively are shifted outward to lock the invoice part and return the invoice part of the separation. Then, as soon as the miner again mounts the locking plate (11, 2), mining installation is again ready for operation. Safety elements 40 while sliding along the guide parts 60 under the hydraulic cylinders 45, providing a clean and optimal entry locking shelves 41 between the miscellaneous parts.

Figure 6 again shows the fixing flush between the members of each other line elements 31, 32 and end shelves 23, 24 response miscellaneous parts or miscellaneous parts. Figure 6, and figure 5, it is seen that section 8 of the gutter, which Rethimno mounted guide part 6 of the machine, as already known in the prior art, can be fitted with a removable chute conveyor (removable chute 80), and the transport plate 81 replacement gutters from stope, i.e. from the side at which the guide portion 6 is mounted on section 8 of the gutter and is blasting coal, is notched groove 28 located on the article the Rhone lava rear side of the upper end of the shelf 23, ensuring the fixation of removable chute 81 from the side of the stope solely through interaction with geometric closure of the transport plate 81 removable chute 80 with miscellaneous parts. In any case, the upper end of the shelf 23 of the C-shaped profile parts which fulfil a dual function, namely partially a function of unilateral fixing removable chute 81, so that the removable chute should be recorded using detachable fixation devices only from the lava, which is not depicted here.

In underground conveyor systems all gutters mining device have limited angular movement by means of pin elements 19 arranged on the guide parts of the plane, and are connected to each other by lava through other bonding elements. When dismantled the guide parts of the plane would have no fixation on the part stope between the trench with removable guide part of the machine and the subsequent trough, for example, another wedge-shaped groove or a standard gutter. Therefore, the invention section of the chute is provided additional means 90 centering and fixation, the construction of which is illustrated only with reference to Fig.7. This 7 shows, in turn, section 8 of the trench with removable chute 81 on the views of bomwollen 13 includes a hydraulic cylinder 45 of the connecting device, and mobile safety element 40, as explained above. Hinged on section 8 of the guide chute of the machine removed. Adjacent to this section of the gutter trough, such as trough 1, here are supplied adamantium stationary rail (1A, figure 1) of the machine, which in Fig.7. for better clarity, is not shown. Cross-shelf 25 miscellaneous parts 20 provided with a transverse hole 29, which in the assembled condition, is located coaxially with and congruent to the cross-hole 17 in the end region located from the side of the stope side cheeks 18 standard chute 1. The side cheek 18 is also provided with a vertical hole 19 in which the ends of the transverse hole 17. When removed from the section 8 of the guide chute of the machine through the coaxially spaced transverse openings 17, 19 can be inserted centering finger 91, which one of its end 92 is in the lock pin 93, which is pushed from above into the vertical hole 19 and is threaded for screwing or the like On the other end 94 of the centering finger is screwed a lock nut 95, so although there is still permitted relative movement standard trench 1 and section 8 of the gutter, but both gutters can not be separated from the side of the stope. Thanks cylindrical installed with a gap in ve the vertical hole of the locking trunnion 93 standard chute 1 and attached to the V-groove 2 can still make the necessary move relative to each other. The tool 90 centering can be, however, disconnected only when dismantled guide part of the plane. In assembled condition, on the contrary, the main efforts are not perceived by the tool 90 centering and pin connections on the guide parts 1A or 6 respectively of a plane.

The safety element ends 40, as particularly well seen in figure 7, over the retaining shelf 41 in short portion 42 of the shelf forked end 43, which when dismantled hydraulic cylinders 45 and/or in case of failure of the hydraulic cylinder 45 can be installed tool that in case of an emergency to be able to move the safety element 40 between a closed position and an open position, or Vice versa. The tool may be, for example, is mounted on the finger 44, which is mounted on the forked end 43 of the safety element 40.

For a specialist from the previous descriptions derive numerous modifications that should be covered in the protection scope of the attached claims. The figures shown one of the preferred embodiments. The lower hook elements or, respectively, the grooves miscellaneous parts and return miscellaneous parts could also form Kruchkova connection, providing the ability to rotate the guide part mash the us in the installation position before making a safety element in its locking position or the closed position. Of course, then the upper miscellaneous parts and return miscellaneous parts commonly are not as funds geometric circuit and, for example, in the form of strips with a corresponding recess into which slides the safety element. These and other modifications should fall within the scope of protection of the attached claims.
