They are large in size, complex to install and operate, high in cost, limited in scope of application, difficult to maintain, and have a short service life and reliability. They are not suitable for special environments and may not work properly or withstand long-term use in high temperature, low temperature, or corrosive environments. At present, there are very few push rope devices suitable for mine rail transportation and they are not applicable. Since the radius of curvature of the auxiliary shaft rail transportation vehicle entering the yard is too large, the vehicle is prone to derailment when transporting large equipment. It is proposed to solve the problem of wire rope eccentricity by replacing the manual fixed guide wheel with a hydraulic push rope device. Summary of the invention

[0003] In view of the above problems, the utility model proposes a hydraulic rope pushing device for auxiliary shaft rail transportation, which aims to solve the eccentricity problem of the traction wire rope of the auxiliary shaft rail transportation.

[0005] Furthermore, the sliding bracket includes two supporting beams arranged parallel to the slide, an inverted L-shaped column vertically fixedly arranged in the middle of the supporting beam, at least four supporting legs arranged on both sides of the supporting beam, the supporting legs are slidably connected to the slide, the large roller shaft is fixedly arranged vertically for rotation on the right side of the inverted L-shaped column, and the small roller shaft is horizontally rotatably arranged in the supporting beam grooves at the right ends of the supporting beams on both sides of the bottom of the large roller shaft.

[0006] Furthermore, the push rope part and the control part are separated from each other and are at least 2 meters apart.

[0007] Furthermore, the control part includes a hydraulic pump station and a control device. The hydraulic pump station is connected to the hydraulic cylinder of the push rope part through a hydraulic oil pipe. The control valve remotely controls the piston rod to push the push rod to drive the sliding bracket to move horizontally.

[0019] Embodiment 2:

[0020] This embodiment is a refinement of the sliding bracket 03 of embodiment 1. Figure 1 To Attachment Figure 5 As shown, the sliding bracket 03 includes two supporting beams 032 arranged parallel to the slideway 02, an inverted L-shaped column 034 vertically fixedly arranged in the middle of the supporting beam 032, at least four legs 033 arranged on both sides of the supporting beam, and the legs 033 are slidably connected to the slideway 02.
