Further, the longitudinal moving assembly may adopt a driving mode of a rack and pinion, the rack is disposed between the two guide rails 110 and parallel to the guide rails 110, and the pinion is disposed on the moving plate 120. Wherein the guide rail 110 and the rack are both mounted to the vehicle chassis.

In this embodiment, to reduce the impact of the climbing assistance mechanism on vehicle passability, the rail 110 and rack may be curved so that the pad assembly 500 may be hidden at a high point away from the ground. That is, the guide rail 110 and the rack are bent upward at a position where the chassis is far from the ground, and the pad assembly 500 is fixed at the bent position when the vehicle is running normally.

The working process of the mine working vehicle provided by the embodiment is as follows:

when the vehicle encounters an unvented obstacle in the forward process, the longitudinal moving assembly 100 moves forwards and brings the cushion plate assembly 500 to the front tire position, then the locking assembly 300 releases the cushion plate assembly 500, the spool 410 rotates and moves the cushion plate assembly 500 downwards to enable the cushion plate assembly 500 to fall to the ground, and the spool 410 continues to release the steel wire rope to leave the activity allowance after the cushion plate assembly 500 falls to the ground, so that the damage of the climbing auxiliary mechanism caused by the fact that the steel wire rope is pulled due to the fact that the cushion plate assembly 500 is motionless when the vehicle advances is prevented. The first telescopic rod 320 is extended during the falling of the pad assembly 500 to move the left pad 510 and the right pad 520 away from each other, thereby allowing the left pad 510 and the right pad 520 to be positioned on the advancing track of the tire.

The back-and-forth and left-and-right positions of the pad assembly 500 need not be precisely defined, but may be set substantially at positions, which serve to reduce the height difference and the width of the ridge. That is, the inclined plane of the backing plate is also connected with a plane for supporting the tire to keep the rising height of the tire after climbing over the inclined plane.

When the tire passes over the obstacle, the pad assembly 500 is located at the rear of the tire, and the spool 410 rotates reversely to pull the pad assembly 500 into the limit groove 221 for fixing. During the lifting process of the pad assembly 500, the first telescopic rod 320 is contracted, so that the first boss 511 can be aligned with the first through hole 222, thereby ensuring the adsorption of the magnetic lifting tool 310 to the pad.

It should be noted that, when the tire passes over the obstacle, the longitudinal moving assembly 100 may drive the turntable assembly 200, the locking assembly 300 and the retraction assembly 400 to move backward, so as to ensure that the pad assembly 500 is located below the retraction assembly 400, and the position is not required to be accurate, and the moving distance of the pad assembly is approximately equal to the moving distance of the tire. To ensure that the pad assembly 500 is smoothly clamped into the limiting groove 221, a flare may be provided at the entrance of the limiting groove 221 for guiding.

The timing of retrieving the pad assembly 500 may be selected according to circumstances when the obstacle is overcome, i.e., the front wheels are retrieved after passing through the obstacle, or all the wheels are retrieved after passing through the obstacle.

When the car is in a blocking state, the turntable assembly 200 drives the pad assembly 500, the locking assembly 300 and the retraction assembly 400 to rotate 180 degrees to adjust the direction of the inclined surface of the pad, and the pad is moved to the rear of the rear wheel under the action of the longitudinal moving assembly 100.

In this embodiment, through carrying the backing plate with the car in order to strengthen the vehicle trafficability characteristic, make the vehicle adaptable more complicated operational environment, improved work efficiency, avoided manual operation's loaded down with trivial details and intensity of labour. The steel wire rope is used for connection, so that flexible connection is realized, smooth movement of the vehicle when passing through obstacles is ensured, and structural damage caused by hard connection due to difficulty in moving is avoided.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
