Description

Technical Field

[0001] The utility model belongs to the technical field of mine support, and in particular relates to a single hydraulic prop moving device used in underground coal mines. Background Art

[0002] With the development of the times and the progress of society, single hydraulic props are now widely used in coal mine tunnel excavation. However, since the rail car has not yet been used in coal mine tunnel excavation and comprehensive mining working faces, the single hydraulic prop can only be moved manually to the advanced support position of the working face. The weight of a single hydraulic prop is mostly higher than 50 kilograms. If it is simply carried by workers on their shoulders, the labor intensity is relatively high. In addition, the hydraulic prop may injure the workers and damage the hydraulic support due to force problems during the transportation process, which will have a certain impact on the company's safe production and social and economic benefits. The existing single hydraulic prop transportation device uses wheeled mobile devices at the bottom. In the harsh working environment of coal mines, the wheeled mobile devices are very limited and have high requirements for the flatness of the bottom plate of the coal mine tunnel. In addition, for a distance of only 20 meters, the hydraulic support needs to be laid down, loaded, fixed, moved to the appropriate position, and then the process is reversed. Therefore, there are many inconveniences in use and maintenance. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0018] A single hydraulic prop moving device for underground coal mines, comprising a clamping device and a moving device, wherein: the clamping device comprises two semicircular clamps 101, and the moving device comprises a push rod 201 and a leg 301, wherein: one end of the two semicircular clamps 101 is rotatably connected through a rotating shaft 102, and the other end is detachably connected through a lock buckle 103, and the lock buckle 103 is fixed on the side of the other end of one of the semicircular clamps 101 relative to the rotating shaft 102; the semicircular clamp 101 is vertically fixedly connected to one end of the push rod 201 near the middle position, and a clamping tooth 203 is provided at the other end of the push rod 201, A pushing handle 202 is set in the middle position of the pushing rod 201, and the supporting leg 301 is a hollow sleeve. The upper end of the supporting leg 301 is inserted into one end of the pushing rod 201 with a locking tooth 203, and a through hole 304 is set at the corresponding position of the locking tooth 203 on the supporting leg 301. An adjusting handle 302 is set on the supporting leg 301, and a regulating valve 303 is set in the adjusting handle 302. The regulating valve 303 is an L-shaped metal rod with certain elasticity. One end of the regulating valve 303 is fixed to the adjusting handle 302, and the other end passes through the through hole 304 and is stuck in the middle of the locking tooth 203 of the pushing rod 201. A supporting foot 305 is set at the lower end of the supporting leg 301.
