(57) Abstract:

The invention relates to the mining industry and is intended for mechanized mining excavation tunneling machines without long stops on the capacity of the conveyor belt. The technical result consists in serviceability when podviganiya end of the drum under discharging head scraper conveyor of the combine. This reduces the complexity of operation, improved efficiency, reliability and performance. The method of controlling the movement of the digging machine includes the destruction of the array processor with simultaneous cleaning of the smitten rock and the movement of the harvester and related mobile platform, which is equipped with an end drum telescopic belt conveyor. The mobile platform is connected to the harvester hydraulic cylinder movement, the rod of which the harvester pulls when moving with simultaneous loading repulsed mass on the conveyor belt. With the relief valve set created in the rod end of the hydraulic cylinder to move the working fluid pressure sufficient to hold the movable platform on meridienne move the moveable platform at full stroke hydraulic cylinder movement, feeding the working fluid in the rod cavity of the cylinder movement. Then automatically interrupt the flow of the operating fluid in the rod of the cylinder chamber from the working of the pumping station of the machine and without stopping the combine operation is repeated, while maintaining the desired tension on the tape, and periodically tightening the mobile platform when operating in automatic mode, the cylinder movement and moving it behind the combine to move the telescopic mechanism for adjusting its length. Device to control the movement of the harvester includes a mechanism of movement, one party associated with the harvester, and the other with the rear support frame of the movable platform, which is equipped with an end drum belt telescopic conveyor lift cylinders with clips. The mechanism of movement is made in the form of a hydraulic cylinder movement, which combine body pivotally connected with the movable platform telescopic belt conveyor. Cylinder movement mounted on a mobile platform dual hinge can be mounted at different heights, as well as alternate implementation of the retention of a mobile platform in place and create the necessary sitsa to the mining industry and is intended for mechanized mining excavation tunneling machines without long stops on the capacity of the conveyor belt.

The known method for mining, including the sinking of the advanced generation, the subsequent expansion of the advanced generation to circuit design and production within the zone of intense fracturing of rocks and fastening generation (ed. St. USSR 1265352, CL E 21 D 9/00, 1986).

The disadvantages of this method include the fact that the harvester with mobile platform while passing the excavation overloads repulsed mass on the conveyor belt and at the same time cannot pull rod of the hydraulic cylinder movement. This mobile platform is not able to remain in place as a safety valve set does not create in the rod end of the hydraulic cylinder movement necessary pressure to hold the movable platform in place and maintain the necessary tension of the conveyor belt for operating the pipeline.

There is also known a method for mining, including mining through the digging machine and the associated mobile platform telescopic belt conveyor and run in the bottom of the destructive operations of the array and cleaning smitten rock mass (RF patent 2032077, CL E 21 D 9/00, E. 21 F 5/00, 1995).

The art is rosedene mining tunneling machines. The known method does not allow a gap at the location of the mobile platform as a relief valve set does not create in the rod end of the hydraulic cylinder moving the pressure of the working fluid sufficient to hold the movable platform in place and maintain the necessary tension of the conveyor belt for operating a pipeline for the transportation of rock mass.

Known terminal station of the conveyor belt containing a set can be moved along the base frame with longitudinal grooves located so that they can move in the longitudinal grooves, the axis of the idler drum mounted on the frame top and bottom roller for the tape, two parallel and connected with the ends of the axis of the tension adjusting drum element, one of which is executed in the form of a screw, one end of which is mounted for movement on the frame, and a hydraulic system (patent RF 2002063, E. 21 F 13/08; B 65 G 42/00, 1993) is adopted for the prototype method.

However, a significant drawback of this design is that the use of an adjusting screw for adjusting the position of the tape tension on the drum is not possible to apply the well-known solution in the case n is a power cylinder, an internal cavity which communicates with the hydraulic system, placed on the frame, while the other end of the screw pivotally connected with the axle of the idler drum and restricts the freedom of adjustment. When the flow of operating fluid from the pumping station harvester rod in the cylinder chamber of the movement section moves forward to disabled the sinking of the harvester. Tensioning of the traction carrier body increases and activates the hardware and tension of the belt is selected from the telescopic conveyor until the establishment of the lower settlement tension.

Closest to the proposed to the technical essence and the achieved result on the device is the mechanism of movement, one party associated with the harvester, and the other side end of the drum telescopic belt conveyor mounted on the frame, and the lifting cylinders with clips, the cylinder mechanism of movement, one party associated with the back support of the main frame (RF patent 2163972, CL E 21 F 13/08, 65 G 47/74, 2001) is adopted for the prototype device.

The disadvantages of the known device is limited scope mobile transshipment point and rigid adherence to the lava. In fact, the movement is of nijera is above the head end of the other conveyor. After a full moving truck to a stop in front leg move forward main frame, by repeated separation and contraction of the hydraulic cylinder plunger until then, until you approach the back of the support. When turning on the hydraulic cylinder of the plunger on the separation occurs, the engagement of the pawl with the rack and the rear bearing of the main frame moves forward. Then include the hydraulic cylinder of the plunger to reduce and dog disengages from the rack. After complete reduction of the hydraulic pusher dog turns on an axis and upsets the wedge, not allowing the dog to interact with a toothed rack and the carriage moves freely forward with gate material handler.

The essence of the method of controlling the movement of the digging machine is the destruction of the array processor with simultaneous cleaning of the smitten rock, the movement of the harvester and related mobile platform, which is equipped with an end drum telescopic belt conveyor, while the mobile platform is connected to the harvester hydraulic cylinder movement, the rod of which the harvester pulls when moving with simultaneous loading repulsed mass on the conveyor belt, when the pressure of the working fluid sufficient to hold the movable platform in place and maintain the necessary tension of the conveyor belt, and after full extension of the piston rod of the hydraulic cylinder movement move the moveable platform at full stroke hydraulic cylinder movement, feeding working fluid in the rod cavity of the hydraulic cylinder movement, then automatically interrupt the flow of the operating fluid in the rod of the cylinder chamber from the working of the pumping station of the machine and without stopping the combine operation is repeated, while maintaining the desired tension on the tape, and periodically tightening the mobile platform when operating in automatic mode, the cylinder movement and moving it behind the combine to move the telescopic mechanism to change the length.

Device to control the movement of the harvester includes a mechanism of movement, one party associated with the harvester, and the other with the rear support frame of the movable platform, which is equipped with an end drum belt telescopic conveyor lift cylinders with clips, the mechanism of movement is made in the form of a hydraulic cylinder movement, which combine body pivotally connected with the movable platform televole hinge can be mounted at different heights, as well as alternate implementation of the retention of a mobile platform in place and create the necessary belt tension, move the movable platform to combine.

The technical result of the proposed solutions is the ease of maintenance when podviganiya end of the drum under discharging head scraper conveyor of the combine, the centering of the tape, reducing the complexity of operation, efficiency, reliability, and performance.

Significant features affecting PA technical result achieved are in causal relationship with the specified technical result.

The sign of "the mobile platform is connected to the harvester hydraulic cylinder movement" is a more convenient option for mobile interaction platform housing the digging machine at the moment when the mobile platform remains in place as a safety valve set creates in the rod end of the hydraulic cylinder to move the working fluid pressure sufficient to hold the movable platform in place and maintain the necessary belt tension for operating a pipeline for the transportation of mountain mA loading repulsed mass on the conveyor belt, with the relief valve set created in the rod end of the hydraulic cylinder to move the working fluid pressure sufficient to hold the movable platform in place and maintain the necessary tension of the conveyor belt allows you to simultaneously combine shipping smitten the rock mass and pull the piston rod of the hydraulic cylinder movement, while the mobile platform remains in place as a safety valve set creates in the rod end of the hydraulic cylinder movement the pressure of the working fluid sufficient to hold the platform in place and maintain the necessary tension of the conveyor belt for operating a pipeline for the transportation of rock mass, i.e. contributes to the implementation of the invention.

The sign "after full extension of the piston rod of the hydraulic cylinder movement move the mobile platform to combine at full stroke hydraulic cylinder movement, feeding working fluid in the rod cavity of the hydraulic cylinder movement allows, as will be fully finished hood rod without stopping the combine automatically, if you are running the combine oil station, feeding the working fluid in the rod cavity of the cylinder before the are getting ready for the combine at full stroke in the cylinder, as contact manometer at the maximum tension force of the conveyor belt includes a telescopic winch mechanism changes the length of the pipeline to loosen the tape. During moving of the movable platform to combine the tension of the conveyor belt is in the acceptable range, it is possible due to the fact that the drum winds up the rope with resistance, as the speed of the winder rope is less than the speed force pulling the rope end of the drum by means of a hydraulic cylinder movement. A sign required for the execution of the invention.

The sign "then automatically interrupt the flow of the operating fluid in the rod of the cylinder chamber from the working of the pumping station of the machine and without stopping the combine operation is repeated to automatically stop the flow of operating fluid in the rod of the cylinder chamber from the working of the pumping station, so after you move forward on full stroke hydraulic cylinder movement flow of the working fluid from the pumping station overlaps that meets the purpose of the invention.

The sign of "the mechanism of movement is made in the form of a hydraulic cylinder movement, with which the housing to the to provide for different heights of the movable platform dual hinge" - the sign, without which the functioning of the device is impossible, since the height of the harvester and the movable platform may be different when the movement of the harvester up or down, and in accordance with this platform fixed bracket with a number of holes in which are mounted the fingers of the double hinge. The double hinge is necessary because the mismatch can be in two planes, for example, height and width. Mobile platform when operating in automatic mode, the cylinder movement periodically that remains in place when pulling the rod harvester, then pulled to the combine and constrain the operation of the harvester over the full stroke of the telescopic mechanism changes the length of the pipeline.

The present invention is illustrated in the drawings, is shown in Fig. 1-6.

In Fig.1 depicts a processor and an associated hydraulic cylinder movable platform, side view; Fig. 2 is the same as in Fig.1 is a top view of Fig.3 is a diagram of the belt telescopic conveyor; Fig. 4 - place setting holder end of the drum and the screw nut; Fig. 5 is a top view of the screw nut; Fig.6 is a longitudinal section of a cylinder peredvizhnicheskogo tunnel conveyor 3, the formation of the grooved shape to the upper branch of the tape, cleaning tape, local adjustment end of the drum in a horizontal plane and pivotally mounting cylinder movement 4. The mobile platform consists of a frame 5, an end of the drum 2, the tray 6, the bracket 7 for articulated mounting of cylinder movement 4, the brackets 8 to hold the end of the drum cleaner tape 9, and set 10 with a safety valve 11. Belt telescopic tunnel conveyor 3 consists of an end of the drum 2, the telescopic mechanism of the change of length 12, the conveyor belt 13, the winch 14, electrocontact pressure gauge 15 and the rope 16. On the platform there is a screw 17 and nut 18 for manual alignment of the tape on the end of the drum 2. Reliance mobile 19 together with the cylinders 20 and lateral displacement 21 is designed to center the tape on the end of the drum 2, lifting, lowering, side shift and leveling of the platform relative to the ground and sides of the excavation. Cylinder movement 4 consists of a rod 22 rod end 23. The mobile platform 1 connects the continuous miner 24 tape telescopic tunnel conveyor 3. The set 10 has a fuse is RMI 1 fixed bracket 7 with a number of holes 25. Cylinder movement 4 two hinges 26, i.e. it has two axes of rotation, can be connected with a bracket 7 mobile platform 1 on any if required height, using the holes 25.

The mobile platform 1 connects the continuous miner 24 tape telescopic tunnel conveyor 3, is equipped with a telescopic mechanism to change the length 12. Harvester 24 with mobile platform 1 during the passage of a generation ship repelled the rock mass on conveyor belt 13 of the conveyor 3. At the same time the harvester pulls the rod 22 of cylinder movement 4. While the mobile platform is 1 remains in place as a safety valve 11 set 10 creates in the rod end 23 of cylinder movement 4 the pressure of the working fluid sufficient to hold the platform movement 1 in place and maintain the necessary tension of the conveyor belt 13 for operating the conveyor 3. Once completed extractor rod 22, without stopping the harvester 24, automatically served the working fluid in the rod cavity 23 of the hydraulic cylinder movement 4 and the mobile platform 1 with a speed more than 10 times the speed of the harvester moves to full x the tension force of the conveyor belt 13 includes a winch 14 telescopic mechanism changes the length of the conveyor 12 to loosen the tape 13. During moving of the movable platform 1 to the harvester 24 the strength of the band 13 is within the acceptable range. This is possible due to the fact that the winch drum 14 wind the rope 16 with resistance. After moving forward the movable platform 1 at full stroke of the rod 22 of the cylinder 4, automatically stops the flow of the operating fluid in the rod cavity 23 of the cylinder 4 from the operating pumping station harvester 24. At the same time without stopping the harvester 24 starts pulling rod 22, and a pressure relief valve 11 set 10 in the rod end 23 of the hydraulic cylinder 4 is again creating a working fluid pressure sufficient to hold the movable platform 1 in place and maintain the necessary tension of the conveyor belt 13. During operation of the harvester 24 together with the telescopic belt conveyor 3, if necessary, you can ensure centering of the conveyor mites on the end of the drum by changing the installation angle of the drum during the rotation of the screws 17, which are mounted left and right of the frame 5, or working together with the cylinders and a lateral offset 21 of the movable supports 19.
