Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of coal mine sleeper track removal, in particular to a coal mine sleeper track hydraulic track remover. Background Art
[0002] Mine rail transportation can fully adapt to changes in transportation distance and the curvature of the tunnel. It can be used in both horizontal and inclined tunnels, and the inclination angle is almost unlimited. In addition, small and medium-sized mines are limited by the height and width of the tunnels and cannot use modern rubber-wheeled vehicles for transportation. Therefore, rail transportation still occupies an important position in mine transportation and is still a major mode of transportation in mines. Even in mines where the raw coal transportation system uses continuous transportation machinery, the transportation of materials, equipment, gangue and personnel still needs to be carried out by rail transportation.
[0003] The mine track consists of two parts, namely the substructure and superstructure of the track. The substructure of the track is the foundation of the superstructure, including the roadbed and ancillary facilities. The superstructure of the track mainly includes the ballast, sleepers, tracks, connecting parts and switches. The tracks in the mine often need to be dismantled. During the dismantling, the spikes or pressure rings that fix the track are removed manually with a horn stick, and then the track, sleepers and other materials are removed. On average, a section of track is 5 meters long and is fixed with 7 railroad timbers or iron sleepers. Each railroad timber uses 4 spikes or pressure rings to fix the track. The traditional method of dismantling a section of track requires manual use of a horn stick to remove 28 spikes or pressure rings. The construction process of this link is quite physically demanding and inefficient. Utility Model Content
[0004] The utility model aims to provide a safer, more labor-saving and more efficient coal mine sleeper track hydraulic track remover to solve the problem that the existing sleeper track manual removal consumes physical effort and has low work efficiency.
[0005] The utility model is realized through the following technical scheme: a coal mine sleeper type track hydraulic track remover, comprising a horizontal hydraulic jack and a lifting frame, the horizontal hydraulic jack comprising a tray, a handle and a running wheel, the lifting frame comprising a crossbeam, the middle part of the crossbeam is arranged above the tray, and the two ends of the crossbeam are provided with a track fixing mechanism for clamping and fixing the tracks on both sides.
[0006] Furthermore, a limiting ring is provided below the middle portion of the crossbeam, and the limiting ring is limited and fixed in the pallet.
[0007] Furthermore, the track fixing mechanism includes a steel wire rope fixedly connected to the crossbeam, the steel wire rope is connected to a clamp, and the clamp includes two hinged clamp handles, one end of the two clamp handles is fixedly connected to the steel wire rope, and the other end is provided with an inward-retracted clamp hook for clamping the track.
[0008] Furthermore, the ends of the two clamp handles are provided with rings for connecting the wire rope.
[0009] The utility model has the following beneficial effects: low cost, simple structure, easy to promote or use, high operational safety performance, can reduce the labor intensity of workers and improve work efficiency. After removing the lifting frame, it can also be used for underground vehicles to go off the road and onto the road. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a coal mine sleeper type track hydraulic track remover of the utility model in conjunction with the accompanying drawings.
[0013] like Figure 1 As shown, a coal mine sleeper type track hydraulic track remover includes a horizontal hydraulic jack 1 and a lifting frame 2. The horizontal hydraulic jack 1 includes a tray 11, a handle 12 and a running wheel 13. The lifting frame 2 includes a crossbeam 21. The middle part of the crossbeam 21 is arranged above the tray 11. Both ends of the crossbeam 21 are provided with a track fixing mechanism 3 for clamping and fixing the tracks on both sides.
[0014] In this embodiment, the dimensions of the horizontal hydraulic jack 1 are 670×325×170mm (length, width and height), the lifting capacity is 3 tons, the stroke is 70mm-500mm, and the weight is 30kg. When used on site, a road block can be placed under the horizontal hydraulic jack 1 to increase the stroke.
[0015] The size of the crossbeam 21 is 1100×100×50mm (length, width and height). It is made by welding a 6mm thick steel plate to a U-shaped channel steel to form a closed channel steel. Lifting rings are welded to both ends of the channel steel using chain links, with a center distance of 0.95m. A circular iron ring is welded in the middle of the channel steel as a limit ring 22, which can be stuck in the middle of the tray 11 of the horizontal hydraulic jack 1.
[0016] The track fixing mechanism 3 includes a steel wire rope 31 fixedly connected to the cross beam 21, the steel wire rope 31 is connected to the clamp 32, and the clamp 32 includes two hinged clamp handles, one end of the two clamp handles is fixedly connected to the steel wire rope 31, and the other end is provided with an inward clamp hook for clamping the track. The clamp 32 is made of a 12mm thick steel plate according to the shape characteristics of the track. The end of the clamp 32 is provided with a ring and fixed to the lifting ring of the cross beam 21 using a 4-point steel wire rope. When lifting, the clamp 32 automatically clamps the track under the action of tension.
[0017] When in use, the hydraulic track demolition device is placed between two tracks, and the clamps 32 at both ends are fixed on the track at the track head to be demolished. The operating handle 12 raises the tray 11 of the horizontal hydraulic jack 1, and the tray 11 drives the lifting frame 2 to rise and demolish the track, and the track is demolished section by section starting from the track head and moving inward.
