At present, the scheme adopted for the transportation and management of production auxiliary materials in coal tunnels is that the production auxiliary materials transported from the ground by material trucks are manually transported to the designated positions on the working face. After the excavation operation is completed, the remaining production auxiliary materials need to be manually transported as the operation progresses. This operation has high labor intensity and complex on-site material management, which greatly reduces the operation efficiency and creates safety hazards on site. Summary of the invention

[0003] The purpose of the present invention is to provide a portable lifting device riding on an H-type belt frame for coal lanes, so as to reduce the difficulty of managing production auxiliary materials in coal lanes at the excavation working face of underground coal mines, reduce the work content of personnel carrying production auxiliary materials, improve the excavation efficiency, and eliminate the safety hazards of random stacking of production auxiliary materials. The present invention can use a lifting machine under limited conditions in coal lanes, and the lifting machine and the cargo placement vehicle it carries can move with the extension of the H-type belt frame.

[0004] The present invention adopts the following technical solution: A portable lifting device for a coal tunnel riding on an H-shaped belt frame, comprising a cargo placing vehicle riding on the H-shaped belt frame and a crane, with the H-shaped belt frame facing the excavation working face as the positive direction, and the cargo placing vehicle being located behind the crane; The cargo placement vehicle includes a cargo platform, four supporting cylinders are installed at the bottom of the cargo platform, and rollers are provided at the bottom of the supporting cylinders; the crane includes a crane platform, four bottom plate supporting cylinders are installed at the bottom of the crane platform, and rollers are provided at the bottom of the bottom plate supporting cylinders. Two top plate supporting cylinders are installed on the side of the top of the crane platform close to the coal wall, a column is provided at the center of the top of the crane platform, a rotator is provided at the top of the column, a cantilever is provided at one end of the rotator, and a motor that can move along the cantilever is provided at the bottom of the cantilever.

[0005] Furthermore, the end of the cantilever is located above the center of the cargo platform.

[0006] Furthermore, the maximum extension length of the supporting oil cylinder and the bottom plate supporting oil cylinder is higher than that of the H-type belt rack.

[0007] Furthermore, the maximum extension length of the supporting oil cylinder and the bottom plate supporting oil cylinder is 100 mm.

[0008] Furthermore, the distance between the supporting oil cylinder and the bottom plate supporting oil cylinder and the two sides of the H-shaped belt frame is 20-50 mm.

[0009] Furthermore, a motor 1 is provided in the rotator, and an output end of the motor 1 is connected to an input end of the reducer.

[0010] Furthermore, the side wall of the column is provided with a plurality of oblique reinforcing ribs, and one end of the reinforcing ribs is connected to the crane platform.

[0011] Furthermore, the motor is provided with a suspension rope for bundling materials.

[0012] The beneficial effects of the present invention are as follows: 1. The present invention changes the traditional fixed crane into a movable crane by using an oil cylinder with rollers, so that a crane can be used in coal lanes where space is limited and the position needs to be changed.

[0013] 2. The present invention designs a cargo platform riding on an H-type belt rack for coal tunnels, which effectively utilizes the space above the H-type belt rack. When used in conjunction with a hoist riding on the H-type belt rack, it can achieve unified and centralized management of production auxiliary materials.

[0014] 3. The crane control system proposed in the present invention is entirely hydraulically controlled and can directly use the hydraulic power source of the H-type belt frame head, which reduces product production costs on the one hand and meets coal mine production safety standards on the other.
