This invention relates to a mining transport for delivering goods.

The purpose of the invention is to increase the reliability of the vehicle and ensure its movement in the mine workings with a Complicated Track Profile.

Figure 1 shows a mine vehicle; figure 2 - ski with a bracket in axonp, - metry; Fig. 3 is a section A-A in Fig. 1 (the moment of passage of the ski of the movable roller when turning); figure 4 - section bb in figure 1 (moment

and in the horizontal planes, the movement of loads of workings with any combination and length of bending of the track is provided.

The vehicle operates the principle of endless haulage using the shuttle scheme as follows.

The drive I, by means of pulleys, transmits the pulling force, respectively, to both branches of the rope 7, the envelope of block 6. In this case, the tension of both ropes is tensioned.

The vehicle contains a drive I with friction pulleys, a device for tensioning the rope 2, a towing platform 3 with a two-sided ski 4 and a bracket to which the rope is attached with a margin at one of the ends laid in a bay on the platform, guiding in the form of a rail track 5, the end block 6 and the rope. A ski 4 with wedge surfaces 9 and 10 with fastening of the rope with 7 clamps I is welded to the bracket 8. For retaining} 1 of both branches of the rope, both on the straight sections of the track and on the sections with a complex artificial profile, between the rails are installed supporting and deflecting devices. In the straight section and on the protuberances, the supporting devices are made in the form of a pair of rollers I2 with a horizontal axis of rotation supporting both branches of the haul rope 7. In the valleys of the path there are rollers on the rocker around the horizontal axis of the balance bar in the form of a spring-loaded two-arm lever 13. For the horizontal the left turn of the set-up 7 with the help of the ski bracket zapreapen on the traction platform 3, which together with the cargo platform 16 moves along the track

At the same time, both branches of rope 7 and wedge surfaces of 9 skis 4 freely pass from the top of rolls 12. When platforms move on the valleys of the track, where a roller is mounted on the swinging balancer 1 3 of the wedge surface 10 of the ski 4 to hold one of the ropes, it acts on the roller, lifting it to pass the rope fastening assembly and ski 4. After the passage of the fastening assembly

, jg Nata balancer under the action of springs returns to its original position, and the roller with the lower part continues to hold one branch of the rope.

Another branch of the rope is held constantly by the lower part of the roller rotating on a rigidly fixed horizontal axis. When moving platforms along a working area with a right turn, the deflecting roles

The deflecting rollers from the verticals 14 hold both branches of the rope 7. The axis of rotation, one of which is mounted on a rigid support 14, and the second on the spring-loaded axis 15. To the traction platform 3 using a conventional rope fastening point on the ski 4 runs freely between pairs of rollers 14.

When moving the platforms along the part of the coupling, cargo production pits with a left turn are attached.

form i 6.

For a horizontal right turn, both deflection rollers with a vertical Köshny axis of rotation are mounted on rigid supports. By a set of supporting and deflecting devices in quantities corresponding to the number of turns of the excavation rail track as in a vertical one.

one branch of the rope 7 is held by the deflecting roller 14, and the other branch is held by the roller 15 on a spring-loaded axis, having the ability to move gg vertically. When the traction platform passes, the wedge surfaces of 9 skis of the hitch 4 are pressed on top of the roller 15, which in this case descends. Mount knot

and in the horizontal planes, the movement of loads in the workings is provided with any combination and sequence of bending paths.

The vehicle operates on the principle of endless haulage using the shuttle scheme as follows.

The drive I, by means of friction pulleys, transfers the pulling force alternately to both branches of the rope 7, which goes around the block 6. In this case, the tension of both branches of the rope is tensioned.

adaptation 2. One of the branches

the rope 7 with the help of the ski bracket 4 is cracked on the towing platform 3, which, together with the loading platform 16, moves along the track

5. When moving platforms on straight sections and on sections with convexities of the track, both branches of the pull rope are supported by pairs of rollers 12. At the same time, both branches of rope 7 and wedge surfaces 9 of skis 4 freely pass from the top of rollers 12. When moving platforms on hollows paths where, to hold one of the rope branches, a roller is installed on the swinging balance bar 1 3 wedge surface 10 of the ski 4 acts on the roller i, lifting it to pass the rope fixing unit and ski 4. After passing the rope fixing unit, the balance bar the springs return to their original position, while the lower part of the roller continues to hold one branch of the rope.

Another branch of the rope is constantly held by the lower part of the roller rotating on a rigidly fixed horizontal axis. When moving platforms along a work site with a right turn, the deflecting roles

ki 14 keep both branches of the rope 7.

The rope mount on ski 4 runs freely between pairs of rollers 14.

When the platforms are moved along the main branch of the rope 7, the deflecting roller 14 is held, and the other branch is held by the roller 15 on the spring-loaded axis, which can be moved vertically. When the traction platform passes, the wedge surfaces 9 of the skis of the hitch 4 are pressed on top of the roller 15, which in this case descends. Mount knot

rope rope cable from gearing with roller. After the passage of the wedge surfaces 9 of the skis, the roller 15 under the influence of the spring returns to its original position and the branch of the rope is again mounted on the roller.

The smallest curvature radius of the road is 16 m, and each pair of rollers 14 gives a rotation angle of 2.5. The total corner rounding is not limited.
