[0024] In order to make the purpose, technical scheme and advantages of the implementation of the utility model clearer, the utility model will now be further described in detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the utility model. The specific implementation scheme of the utility model is as follows:

[0025] A mining crawler cable haulage vehicle structure comprises: a crawler vehicle 1, the upper end surface of the crawler vehicle 1 is provided with two parallel columns 2 in a fixed structure manner, the corresponding columns 2 are internally sleeved with a gantry bracket 3 composed of a crossbeam and two legs, and the lower end surface of the legs is provided with a push plate 4 in a fixed structure manner; the crawler vehicle 1 is provided with a worm gear screw lift 5 in a fixed structure manner, and the columns 2 and the legs are internally sleeved with a screw 6 of the worm gear screw lift 5 in a rotatable manner, and the screw 6 is connected to the push plate 4 in a threaded engagement manner; a connecting rod 7 is provided between the two worm gear screw lifts 5, and the two ends of the connecting rod 7 are respectively connected to the input shafts of the two worm gear screw lifts 5; the crawler vehicle 1 is provided with a reduction motor 8 in a fixed structure manner for driving the connecting rod 7 to rotate.

[0026] The connecting rod 7 is driven by the reduction motor 8, which in turn drives the screw 6 of the worm gear screw lift 5 to rotate. The push plate 4 connected to the screw 6 by threaded engagement supports the support leg to move upward or downward, thereby automatically adjusting the height of the cable consignment, freeing up labor and improving work efficiency.

[0027] It should be noted that a limit ring 9 is provided on the upper end surface of the column 2 in a fixed structure manner, the inner edge of the limit ring 9 protrudes from the inner wall of the column 2, and the side wall of the push plate 4 contacts the inner side surface of the column 2 in a sliding structure manner; this structure prevents the support leg from being pushed out of the column 2 by the push plate 4, thereby ensuring the stability and safety of the overall structure.

[0028] It should be noted that a sealing ring 10 is arranged on the inner wall of the limit ring 9 in a fixed structure manner; this can prevent external coal slime, oil stains and debris from entering the interior through the gap between the column 2 and the leg, avoid the screw rod 5 being contaminated by debris and causing wear, increase the service life, reduce the frequency of repair or replacement of the screw rod 5, and save costs.

[0029] It needs to be explained that a box is arranged outside the worm gear screw lift 5, the connecting rod 7 and the reduction motor 8, and the box is connected to the crawler vehicle 1 in a fixed structure. This arrangement protects the above-mentioned structures from the influence of the external environment and increases the service life of the equipment; a coupling 11 is arranged at the input end of the worm gear screw lift 5, and the coupling 11 is connected to one end of the connecting rod 7 to compensate for the installation error between the worm gear screw lift 5 and the connecting rod 7, reduce interference and improve work efficiency.

[0030] The working principle and working process of the utility model are as follows: during the process of transporting cables, when the height of the transported cables needs to be adjusted, start the reduction motor 8, and drive the connecting rod 7 to drive the screw 6 of the worm gear screw lift 5 to rotate. The screw 6 is connected to the push plate 4 by threaded engagement. The rotation of the screw 6 will drive the push plate 4 to move up and down. The push plate 4 is fixedly connected to the lower end surface of the support leg, so that the support leg is supported by the push plate 4 to move up and down, thereby realizing automatic adjustment of the cable transport height.
