Supporting device for coal mining and using method thereof

Abstract

The invention discloses an supporting device for coal mining. The device comprises a base, a trapezoidal frame is assembled at the top end of the base, a buffering reminding mechanism is connected tothe top end of the trapezoidal frame through screws, a storage battery is assembled at the top end of the base, and a hydraulic oil cylinder is connected to the center of the bottom end of the trapezoidal frame through screws. The bottom end of the hydraulic oil cylinder extends into an inner cavity of the base to be connected with a first rectangular plate through screws, the four corners of thebottom end of the inner cavity of the base are each provided with one end of a guide rod, and the other ends of the guide rods extend out of the upper surface of the first rectangular plate to be welded to the top end of the inner cavity of the base. According to the supporting device, workers can conveniently conduct transportation and rotation, the labor intensity of the workers is relieved, useis facilitated, a pressure in the supporting process can be buffered through the buffer reminding mechanism, and when pressing is too large or collapsing occurs, a T-shaped column is promoted to makecontact with a touch sensor. Therefore, an alarm gives an alarm to remind the workers, and the safety in use is improved.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to a support device for coal mining and a method for using the same. Background technique [0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig underground tunnels to mine coal. This is an underground coal mine, and coal is the most The main solid fuel is a kind of combustible organic rock. It is a lush plant that grows in a certain geological age. In a suitable geological environment, it gradually accumulates into a thick layer and is buried in the bottom of the water or in the sediment. Formed by the natural coalification of the 1990s, the mining of coal mines is inseparable from the support of support; [0003] The existing support structure adopts a bracket-type fixed structure...

AI Technical Summary

Problems solved by technology

[0003] The existing support structure adopts a bracket-type fixed structure. Due to its heavy weight, it is not easy to move in the roadway, and it is not convenient for the staff to transport and rotate it, which is not conducive to use. At the same time, during use, when it collapses or the pressure is too high When it is too large, the alarm cannot be reported in time, which reduces the safety during use
