In order to connect the support plate 3 with the crawler, a plurality of connecting frames 12 are fixed on the support plate 3, one end of each connecting frame 12 is fixedly connected with the support plate 3, and the other end of each connecting frame 12 is detachably mounted on a roller support frame of the crawler through bolts.

In order to fix the tire on the disc 6, a plurality of C-shaped clamping claws 13 are uniformly distributed on the circumference of the upper end of the disc 6, the opening ends of the clamping claws 13 face outwards, and the inner edge of the used tire 8 is clamped and fixed through the clamping claws 13.

In order to realize the support of the chain wheel 1 to the chain 2, a plurality of supporting wheels are arranged in the chain 2, and the supporting wheels are rotatably arranged on the supporting plate 3.

In order to facilitate the installation of the disc 6 and the polish rod 5, an outward bulge is fixed on the outer side of the disc 6, and the lower end of the polish rod 5 is fixed on the bulge.

In order to facilitate the installation of the rotating wheel 11, a U-shaped frame is arranged on the supporting rod 9, and the rotating wheel 11 is rotatably installed on the U-shaped frame.

The specific working process of the invention is as follows: when the device is in an initial state, the tire is not stressed downwards, the springs 7 contract to enable the polished rod 5 to drive the disc 6 to be close to the L-shaped pipe 4, the lower end of the disc 6 leaves the ground, meanwhile, the supporting rod 9 drives the rotating wheel 11 to rotate downwards and enable the rotating wheel 11 to be in contact with the ground under the action of the coil spring 10, when the device is installed, the crawler is firstly driven onto a used tire 8 on one side of the crawler, one end of the crawler is tilted when moving, so that the crawler can easily go onto the tire, when the crawler is placed on the tire, the rotating wheel 11 is stressed and enables the rotating wheel 11 on the same disc 6 to contract inwards to enable the lower end of the disc 6 to be in contact with the ground, the supporting rod is lifted upwards, the springs 7 are stretched, the device is fixed on a roller supporting frame of the crawler through the connecting frame 12, one device is respectively installed on the crawler on two sides, when the crawler moves leftwards, the track presses the used tire 8 arranged below the track, the chain 2 cannot slide relative to the ground, but the tracked vehicle continuously moves, so the tracked vehicle drives the chain 2 to rotate relative to the tracked vehicle when moving, the chain wheel 1 supports the chain 2 when rotating, the chain 2 drives the L-shaped pipes 4 fixed on the chain 2 to move during rotation, the length of the chain 2 is more than that of the track, the used tire 8 arranged below the track is pressed by the track and cannot move relative to the ground, the spring 7 on the polished rod 5 provides a margin for up-and-down expansion for the disc 6, so that the connection between the support plate 3 and the disc 6 can be stably kept, the tire arranged below the track is gradually arranged on the right side of the track and is gradually separated from the extrusion of the track along with the continuous left movement of the engineering vehicle, the return of the spring 7 and the return of the coil spring 10 can enable the disc 6 to move upwards, and the rotating wheel 11 extends out of the lower end of the disc 6, the lifted used tire 8 slides leftwards relative to the crawler from the right side along with the continuous left movement of the crawler, the L-shaped pipe 4 at the position is changed from the side originally arranged close to the crawler to the side far away from the crawler in the process, the L-shaped pipe 4 is changed from the original right movement relative to the crawler to the left movement relative to the crawler, then the L-shaped pipe 4 is arranged on the side close to the crawler by bypassing the chain wheel 1 on the left side, the L-shaped pipe 4 is changed from the left movement relative to the crawler to the right movement relative to the crawler again, the used tire 8 on the L-shaped pipe 4 is rolled by the crawler again and forms protection for the crawler and the ground of the crawler along with the continuous left movement of the crawler, the spring 7 is stretched after the used tire 8 is squeezed, so that the lower end of the disc 6 contacts the ground, and the rotating wheel 11 is twisted by the squeezing coil spring 10, so that the rotating wheel 11 retracts to the upper end of the disc 6.

According to the invention, the disc 6 can be reset upwards when not pressed through the spring 7, the rotating wheel 11 hinged on the disc 6 can extend downwards when not pressed under the action of the coil spring 10 and retract inwards when pressed, and the old tire 8 is circularly padded below the track in the continuous moving process of the crawler, so that the track is not in contact with the ground, the effect of protecting the road surface and the track is achieved, and meanwhile, the old tire 8 is lifted up to reduce the friction between the old tire 8 and the ground when not participating in supporting the track, so that the device is low in noise, low in power consumption, safer and more durable when in use.
