Abstract

FIELD OF THE INVENTION The invention relates to the mining industry, in particular to cable-moving supply mechanisms. The purpose of the invention is to increase the movement in one step and the angle of inclination of the feed direction by increasing the thrust force. The inner and outer frame (P) are telescopically interconnected. Three blocks of the 7, 8, 9 polyspast system are located on the internal P axis. Blocks 26, 27, and 28 are mounted on the axis of the outer P. The axes of the inner and outer P are placed in longitudinal grooves with the possibility of moving along them. The transmission mechanism has supporting elements made in the form of supporting shoes. The boots hinged on some rachags are connected with movable axles, and through other levers - with fixed axles. The movable axes are pairwise linked through m. The drive of the feed mechanism is made in the form of a double drum winch and has two ropes 34, 36 fixed at one end respectively on the drums 38, 39 of the winch. The other ends of the ropes 34, 36 are fixed respectively on P. In the initial position, both P are shifted. Having loosened the rope 34 and pulling the rope 36 through the polyspast system, they bring together the axes of the inner and outer P, which leads to the pressing of the boots of the outer P to the walls of the well and withdrawing the shoes from the walls of the well. This ensures the free movement of the outer R. With the further winding of the rope 36 onto the drum 39, the inner P moves by one step. Loosening the rope 36 and winding the rope 34, similarly move one pitch external R. 3 Il.

The invention relates to the mining industry, in particular to rope-walking feeders.

The purpose of the invention is to increase the movement in one step and the angle of inclination of the feed direction by increasing the thrust force.

FIG. 1 shows the rope-sliding feeder, general view; in fig. 2 is a section A-A in FIG. J; in fig. 3 - the scheme of ropes storing. The cable-walking feeder consists of two inner and outer frames 1 and 2 that are telescopically interconnected. Inner frame 1 is connected to a working body that needs to be fed in an operating cycle. Each frame has four pairs of support shoes 3 and 4, by means of which the device is supported into the walls of the well. The frames 1 and 2 have the possibility of mutual movement along the guides 5 and 6 by the amount of walking. On the inner frame 1 there are three blocks 7-9 of the polyspast system on the axes 10 and 11 placed in the longitudinal grooves 12 and 13, the length of which is chosen depending on the amount of support shoes moving away from the borehole walls. The pads 3 and 4, hinged on the levers 14 and 15, are connected to the movable axes 10, 11, 16 and 17, and through the levers 18 and 19 to the fixed axes 20-23, forming the supporting elements. Axes 10 and 16 are connected to axes 11 and 17 through tractors 24, which are installed in longitudinal pa, eax, similar to grooves 12 and 13. Plates 25, having longitudinal grooves for accommodating axes and rigidly mounted on the ends of outer frame 2, cover guides (fig. 2).

On the outer frame 2 there are three blocks 26 - 28 on the inner axis 29; - the frames rigidly located at the ends of the frame 2, covering the guides 6 (Fig. 2). Otherwise, the device frame 2 is similar to the device frame 1 o The shoes 3 and 4 of the frame 2 are hinged on the levers 14 and 15, connected with. movable axes 30–32, which are connected with the axes of frame 1 by means of the gigi 33.

FIG. Figure 3 shows the scheme of the supply of traction feed channels. Rope 34 through blocks 7, 27 and 8 is connected at one end with the inner frame 1 in place

35 fasteners. The other rope 36, through the blocks 26, 9 and 28, is connected at one end to the outer frame 2 at the attachment point 37 by the other ends, the ropes 34 and 36 are connected to the drum 38 and to the drum 39 of the double-drum winch, respectively.

The device works as follows.

In the initial position, the telescopic frame 1 and 2 are retracted. The shoes 3 and 4 of frame 1 are pressed by the tension force in the rope 34 to the walls of the well. At the initial moment of movement, the rope 34 is weakened and gets the opportunity to disband. In the rope 36, a tension is created, which, through the polyspasty system of the blocks 26, 9 and 28, pulls the axes 29 and 11 of the blocks. The convergence of the blocks of the polyspast system is accompanied by the opposite movement of the axes 11 and 29, as well as the associated rigid rods 24 and 33 of the axes 10, 16 and 17 of frame 1 and axes 30 and 32 of frame 2, respectively, in the longitudinal grooves, which leads to pressing of the shoes 3 and 4 frames 2 to the walls of the well and removal of the shoes 3 and 4 frames 1 from the walls of the well. This allows the inner frame 1 to move freely.

With further rope winding

36to the drum 39 in the shoes 3 and 4 of the outer frame 2 creates a thrust force from the transmitted block-lever system, the tension in the rope and the axis 11 of the frame 1, approaching

to the axis 27 of the frame 2, it is moved forward along with the rigid axis 24 of the rigid axis 24 connected with it, axes 10, 16 and 17 of the frame 1, which leads to the extension of the inner frame 1 to a distance of one step.

The rope 36 is then weakened and gets the opportunity to reel freely from the drum 39, at which time the rope 34 is wound on the drum 38, and the outer frame 2 is likewise pushed forward by one step.
