(57) Abstract:

The invention relates to the field of mining industry, in particular for constructive drill carriages, and is a device for guiding a flexible elements, such as hoses, around the drum for hose along the feed beam for moving the drill hammer. In the construction according to the invention the flexible elements are installed around the same drum hoses for at least two consecutive layers in the radial direction of the reel for hoses, each radial layer is mounted on a shaft so that it can rotate around the axis of the reel for hose independently of other layers. The drum design differs in that it has multiple disks, between which are formed grooves for accommodating at least one of the flexible elements, and at least two flexible element is able to rotate around the drum, and each flexible element is able to rotate around the axis of the drum independently of the other flexible elements. The invention provides improved reliability in operation of the drill carriage. 2 C. and 7 C.p. f-crystals, 4 Il.

The invention relates to a device for guiding a flexible elementui, moreover, in this device, the flexible elements attached at least at one point in their longitudinal direction is stationary relative to the feed beam is directed to move to the rear end of the beam supply around for hose drum, which rotates around an axis essentially perpendicular in relation to the feed beam, and moving at a speed equal to half speed (feed) hammer drill, relative to the feed beam for drilling with a hammer in the direction coinciding with the direction of velocity (feed) hammer drill, and then to the drill hammer or slide hammer drill.

In addition, the invention relates to a rotor construction for hose designed for guiding the flexible element to the drill hammer, moving along the feed beam, and the design for hose drum includes a drum for hoses, which rotates around an axis and includes control means for each flexible element, such as a guide groove or similar, intended for the direction of the flexible elements in a predetermined manner around the drum for hoses.

To ensure the functioning of drill hammers to n who needs to hold the hose in a straight position and to maintain a certain tension. Typically, this is achieved by the fact that the hoses have so that they move from the hammer drill in the direction of the rear part of the feeding the cutter around the drum for hoses that are in the back, and forth to the front of this beam and by ensuring consistency of movements hammer drill and reel for hose so that the reel for hose moves in the same direction as the drill hammer, but with a speed equal to half speed hammer drill, and thus half the distance by which to move the drill hammer. In the known solutions of all hoses are moved around the same design of the drum, so that the hoses are on top of each other in the axial direction of the drum. In addition, if you use a cylindrical feed feeder cable, which is used as hoses, to rotate the reel for hoses in order to achieve its movement, the applied reels for hoses become quite high. As a result, the drum hoses, usually located much further in relation to the drill hammer according to the height of the feeding beam and, therefore, the upper the Colo surface of the tunnel. In some known solutions use a pulley for a cable that does not have an independent drive and which is coaxial in relation to the existing drum for hoses, but even in this case they are arranged successively in the axial direction of the reel for hose, thus forming a structure having a relatively large height. Such solutions are known from U.S. patent 3500941 and posted descriptions of unaccepted application for patent in Germany 2419470.

The aim of the present invention is to develop a device and the drum structure for hoses that allow you to eliminate the disadvantages of the known solutions and to get the drum design for hose having a smaller height than the known, and to ensure that hoses and possibly the cable to move the drum to the hoses. The device according to the invention is characterized in that the flexible elements are stacked around the same reel for hose, at least two successive layers in the radial directions of the reel for hoses, and each radial layer is rotated so that it rotates around the axis of the reel for hose independently of other layers. The design of the reel for hose according to the invention Otley which can be placed, at least one of the flexible elements with the smallest diameter, the outer edges of the disks of the drum have a support surface adapted to provide support for the flexible elements with diameters greater than the width of the groove, to allow flexible placement of elements greater thickness so that they could rotate around the drum for the hoses on the abutment surfaces of the grooves, thereby, at least two flexible element to rotate around the drum for hose radially in grooves, and each flexible element is mounted on a shaft so that he rotates around the axis of the reel for hose independently of the other flexible elements in the same groove.

The essential idea of the invention is that the flexible elements, i.e. rods and possibly the cable, arranged in series in the radial direction of the reel for hoses, so that at least two of the hose or the hose and cable are arranged successively in the radial direction and the axial essentially in one and the same point, so that they form at least two layers in the radial direction of the reel for hoses. Following the essential idea of the invention is that the hose or the hose and the cable in different places one is for hose independently from each other, thus, they can move freely and be installed in a certain position properly, naratiwas around the drum for hoses.

The advantage of the device and the drum structure for hose according to the invention is that, using hoses of appropriate thickness, it is possible to position the hoses and cables so that they will move together, as on top of each other and side by side, thereby the reel for hose becomes lower, and allows a more simple and easy directions hose to the drill hammer. Furthermore, the reduced risk of damage to the reel for hoses and achieved the orientation angle of less size, which minimizes unnecessary destruction and to facilitate drilling.

The invention is described in more detail with reference to the attached drawings, in which:

Fig. 1 schematically shows the movement of the hoses from hammer drill to the drum for hoses and around him;

Fig. 2 schematically shows a side view and partially in section of the drum design for hoses that are applicable in the apparatus shown in Fig. 1;

Fig. 3 schematically shows a partial view of another variant implementation of sborn the third variant embodiment of the invention, in which three hose or similar with different diameters mounted for movement successively in the radial direction of the reel for hose.

In Fig. 1 shows the structure of conventional feed beam 1 for a hammer drill, which moves the drill hammer 2. The drum 3 for hose, around which revolve flexible elements, i.e. hoses 4A-4E and 4f rope, is located behind the drill hammer 2 at the rear end of the feed beam 1. Hoses 4A-4E are attached at one end to the drill hammer 2, and they rotate around the drum 3 for hose and returned to the front end of the feed beam 1, and they are fixedly mounted relative to the feed beam 1 by means of a clamp 5 attaching hoses. From clip 5 mounting hoses hoses pass on to the carriage (not shown) hammer drill. The 4f rope attached at one end to the carriage (not shown) hammer drill 2, similarly rotates together with hoses 4a-4d around the drum 3 for hose and attached the other end to the feed beam 1. The hose construction and working principle of hammer drill known and obvious to specialists in this area and the detail is not described here.

As OYe drum 3 for hose, and two hose or the hose and cable are located side by side at each point in the radial direction of the reel for hose and the inner hose and the cable rotates the drum 3 for hose along the lower arc.

In Fig. 2 schematically shows the design of the reel for hose according to the invention is shown in Fig. 1, through which the hoses can be placed so that they can move, as shown in Fig. 1. In Fig. 2 shows the drum 3 for hose, and he is depicted partially in combination to illustrate the exact design of the drum. The drum 3 for hose attached to the carriage 6 of the drum and rotates around the axis 7. The drum 3 for hose formed of four disks 3a-3d drum installed at each other in the axial direction of the reel for hoses and fixed to each other by bolts 8, so that they form a stationary part of the drum. Guide rings 10a-10c with a concave outer surface located between the disks 3a-3d of the drum, each with its own bearing 9a-9c. Hoses 4d and 4E with smaller diameters and rope 4f posted by these guide rings. Thus, they can turn freely relative to the rest of the reel for hose on its supporting surface 3', which is carved on the outer edges of the disks 3a-3d of the drum, thereby hoses 4A-4C rely on the disks of the drum and can't go deeper into the grooves between the discs of the drum. Forming one node in the stationary part of the drum formed by the disks of the drum, mounted on the shaft 7 on the bearings 11a-11b, thereby, when the drum 3 for hose rotates around the axis 7 with the speed achieved when moving hoses 4A-4C, hoses 4d and 4E with smaller diameters and rope 4f rotate independently of the drum 3 for hose and hose 4A-4C with large diameters.

In Fig. 3 schematically and partially shows another variant of implementation of the construction of the reel for hoses that are applicable in the device according to Fig. 1. In this embodiment, separate supports for hose for hose reel 3 is designed so that the disks 3A-3d hoses form a stationary zheloboobraznogo grooves between them, around which the hose 4d, 4E with smaller diameters and rope 4f rotate with the same speed. Similarly, rotation of the outer hose with large diameters by using bearings 12a-12d with the supporting washers 13a-13d on them set around the disks 3a-3d of the drum. The thrust washers 13A and 13d made in this way, the PWM diameter rely on support surface 13' of the support washers 13a-13d and can rotate relative to the disks 3a-3d with independent speed and thus all the hoses and cable can move at an appropriate speed relative to each other during rotation of the drum 3 for hose.

In Fig. 4 schematically and partially shows a third variant of implementation of the design for hose drum according to the invention, in which the combined solution according to Fig. 2 and 3. In this figure, as in Fig. 3, a reel for hoses shown only partially to illustrate ideas. As shown in Fig. 2, in this embodiment, the drum 3 for hose has a separate rotatable thrust washer 10A, rotating between the disks 3A and 3b of the drum bearing 9a. Thus, a hose with small diameter or wire can rotate freely relative to the disks 3A and 3b of the drum. Zheloboobraznogo support surface formed on the disks 3A and 3b drum and other relevant disks on which the hose 14a with a large diameter hose can be rotated on the side of the reel for hose, formed by the disks 3A and 3b drum rotating at the same speed. The thrust washers 13A and 13b mounted on the disks 3A and 3b on separate bearings 12A and 12b, and the hose 14C with a large diameter compared to the inner hose again can rotate freely on the specified reference washers regardless of cosmonet move many hoses and maybe rope in only two planes, resulting in the design of the reel for hoses, having a very small height.

In the above description and in the drawings the invention has been described and shown only as examples, and of course, it should not be limited by this example. Two or more hoses can be stacked on each other in the radial direction, or in some cases, the number of hoses in various locations in the axial direction of the drum hoses may vary. Furthermore, the design according to the invention can be applied so that the hoses will be installed so that they can move only one line and one line with the cable, which is designed to move the reel for hose and is located so that it is moved at the bottom of the groove with a hose on the bearing installed on the bottom of the grooves, thereby eliminating complicated and significant height of the drum structure for a hose, which is due to be used in normal cases, a separate pulley for rope. However, it is essential that the hoses on the same reel for hoses installed on the axle so that they can rotate independently otavalenos direction.
