As can be seen from fig. 1 to 4, the invention comprises two chain wheels 1 which are placed left and right and have vertical axes, the two chain wheels 1 are connected through a chain 2, the upper ends of the two chain wheels 1 are provided with a support plate 3, the chain wheels 1 are rotatably installed on the support plate 3, the support plate 3 is detachably installed on a roller support frame of a crawler belt, a plurality of hinge lugs 4 are uniformly distributed on the chain 2 at intervals, each hinge lug 4 is provided with an L-shaped pipe 5, the transverse pipe end of the L-shaped pipe 5 is hinged on the hinge lug 4, the vertical pipe end is downwards inserted and provided with a polish rod 6 which can move along the vertical pipe end, the lower end of the polish rod 6 is fixed with a disc 7 which is vertical to the polish rod, the polish rod 6 is sleeved with a spring 8, one end of the spring 8 is fixed on the disc 7, the other end is fixed at the end of the stand pipe, a used tire 9 is detachably mounted on the upper end face of each disc 7, a horizontal guide rod 10 is arranged on one side, away from the crawler belt, below the chain 2, a horizontal spiral rod 11 is fixed at each of the two ends of the guide rod 10, the spiral rod 11 bypasses the outer side of the corresponding chain wheel 1 and shrinks towards the inner side of the chain wheel 1 on one side, close to the crawler belt, of the chain 2, the spiral rod 11 is smoothly connected with the guide rod 10, when the crawler belt moves leftwards, the L-shaped pipe 5 is guided and supported by the spiral rod 11 on the right side and enables the lower end of the L-shaped pipe to be lifted upwards when moving along with the chain 2, the discs 7 are kept to be separated from the ground under the support of the guide rod 10, and then are separated from the spiral rod 11 on the left side.
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 realize the installation of the guide rod 10 and the screw rod 11, a support rod 13 is fixed at the lower end of the chain wheel 1, the chain wheel 1 is rotatably connected with the support rod 13, and the guide rod 10 and the screw rod 11 are fixed on the support rod 13 through a plurality of support rods.
In order to fix the tire on the disc 7, a plurality of claws 14 are uniformly distributed on the circumference of the upper end of the disc 7, the claws 14 are C-shaped and have outward openings, and the inner edge of the used tire 9 is clamped and fixed through the claws 14.
The specific working process of the invention is as follows: when the device is used, the engineering vehicle is firstly driven to the used tire 9 on one side, and the device is fixed on the roller support frame of the crawler through the connecting frame 12, the crawler on two sides is respectively provided with the device, the engineering vehicle moves leftwards when the engineering vehicle walks, the crawler presses the used tire 9 arranged below the engineering vehicle at the moment, the chain 2 cannot slide relative to the ground, but the engineering vehicle continuously moves, so the engineering vehicle drives the chain 2 to rotate when moving, the chain wheel 1 provides support for the chain 2 to rotate, the chain 2 drives the L-shaped pipes 5 hinged on the chain 2 to move in the rotating process, the length of the chain 2 is more than that of the crawler, the used tire 9 arranged below the crawler is pressed by the crawler and cannot move relative to the ground, the spring 8 on the polished rod 6 provides a vertical telescopic allowance for the disc 7, and the supporting plate 3 and the disc 7 can be stably connected, with the continuous left movement of the engineering truck, tires arranged below the crawler are gradually arranged on the right side of the crawler, the L-shaped pipe 5 is gradually contacted with the screw rod 11 on the right side and slides along the outer side of the screw rod 11, the L-shaped rod drives one end of the disc 7 to be lifted upwards in the process, the expansion and contraction of the spring 8 enable one end of the L-shaped rod with the disc 7 to be lifted so that the used tires 9 are gradually separated from the ground, the lifted used tires 9 are shifted from the screw rod 11 on the right side to the guide rod 10 and slide leftwards relative to the engineering truck along the guide rod 10 in the process, the L-shaped pipe 5 at the position is changed from the original side close to the crawler to the side far from the crawler to the original side relative to the engineering truck from the right side to the left side relative to the engineering truck, the L-shaped pipe 5 is then rotated from the guide rod 10 to the left screw rod 11 and is placed close to the crawler belt around the outer side of the left chain wheel 1, at the moment, the L-shaped pipe 5 is changed from moving leftwards relative to the engineering truck to moving rightwards relative to the engineering truck, at the moment, the L-shaped pipe 5 is disengaged from the left screw rod 11 and is placed at the left end part of the crawler belt under the self weight, and as the engineering truck continuously moves leftwards, the used tire 9 on the L-shaped pipe 5 is crushed by the engineering truck again and forms protection for the crawler belt and the ground of the engineering truck.
The invention has the advantages that:
1. this device utilizes the drive power of machineshop car itself, and one side is pushed down used tire 9 with the track and is made the chain 2 of this moment can not remove ground relatively, and the relative machineshop car of removal drive chain 2 of machineshop car rotates simultaneously, realizes filling below the track with 9 reciprocating cycle of used tire for this device uses limited several used tire 9 can realize the protection to track and road surface under no external force intervenes, makes the machineshop car move the operation in the short distance simple and convenient more.
2. The old tire 9 which does not participate in supporting the crawler belt is lifted to the ground through the wire guide rod and the two spiral rods 11, the friction force between the disc 7 and the ground is reduced in the process, the noise problem caused by friction can be effectively reduced, meanwhile, the loss of kinetic energy and the abrasion of the device can be effectively reduced, and the whole device is safer and more reliable in the using process.
3. This device acts as the filler through used tire 9, not only can effectually practice thrift the cost, can also realize waste utilization, and the tire is bigger and thick and very durable for the lath simultaneously for the protection effect of this device is better and environmental protection more.
