In order to facilitate the installation of the rotating wheel 20, a U-shaped frame is arranged on the supporting rod 18, and the rotating wheel 20 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 15 contract to enable the polished rod 13 to drive the disc 14 to be close to the vertical pipe 12, the lower end of the disc 14 leaves the ground, meanwhile, the support rod 18 drives the rotating wheel 20 to rotate downwards under the action of the coil spring 19 and enables the rotating wheel 20 to be contacted with the ground, when the device is installed, the crawler is firstly driven on a used tire 16 on one side of the inwards concave belt 6, 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 20 is stressed and enables the rotating wheel 20 on the same disc 14 to contract inwards and enable the lower end of the disc 14 to be contacted with the ground, the support rod is lifted upwards, so that the springs 15 are stretched, the device is fixed on a support frame of the crawler through the connecting frame 21, the crawlers on two sides are respectively provided with the device, and the crawler moves leftwards when walking, the track presses the used tire 16 which is arranged below the used tire, the belt 6 which is close to one side of the track is far away from the corresponding first track groove 2, therefore, when the driving belt 6 rotates, the belt 6 on the side is not contacted with the friction plate 10, therefore, when the corrected tire is pressed by the track again, the corrected tire does not move relative to the ground, but the crawler continuously moves, therefore, the used tire 16 which is not driven by external force can be changed from the left end of the track to the right end of the track, when the used tire 16 moves to the right end of the track and is gradually separated from the track pressing, the length of the chain is more than that of the track, along with the continuous left movement of the engineering vehicle, the return of the spring 15 and the return of the coil spring 19 can enable the disc 14 to move upwards, the rotating wheel 20 extends out of the lower end of the disc 14, along with the continuous left movement of the crawler vehicle, the friction plate 10 gradually contacts with the belt 6, the belt 6 and the friction plate 10 are driven by friction, so that the used tire 16 slides to the left relative to the crawler from the right rapidly, the used tire 16 at the position is changed from the side originally arranged close to the crawler to the side far from the crawler in the process, the used tire 16 moves to the left rapidly relative to the crawler from the original right direction relative to the crawler, then the used tire 16 bypasses the belt pulley 4 at the left side and is arranged at the side close to the crawler, the used tire 16 is arranged below the crawler, the used tire 16 is rolled by the crawler again and forms protection for the crawler and the ground after being squeezed, the spring 15 is stretched after the used tire 16 is squeezed, the lower end of the disc 14 is contacted with the ground, and the rotating wheel 20 is twisted by the squeezing coil spring 19 to realize the retraction of the rotating wheel 20 to the upper end of the disc 14.

The invention realizes that the disc 14 can be reset upwards when not pressed through the spring 15, the rotating wheel 20 hinged on the disc 14 can realize that the disc 14 extends downwards when not pressed under the action of the coil spring 19 and retracts inwards when pressed, the used tires 16 are circularly padded under the crawler in the process of continuously moving the crawler, so that the crawler is not contacted with the ground, the effect of protecting the road surface and the crawler is achieved, meanwhile, the used tire 16 is lifted when not participating in supporting the crawler belt so as to reduce the friction between the used tire and the ground, so that the device has low noise, needs less power and is safer and more durable when in use, meanwhile, the used tire 16 below the crawler belt is not driven by external force and is relatively static oppositely, when the used tire 16 is not arranged below the crawler belt and only needs to be transported, the used tires 16 are rapidly transported to the left end of the crawler belt to participate in the work through the acceleration of the belt 6, so that the number of tires can be effectively reduced.
