Problems solved by technology

[0002] In the process of coal mining, it is necessary to extend the mine tunnel and reinforce it to prevent subsidence. Although the commonly used reinforcement devices can prevent the mine tunnel from collapsing during use, they cannot detect whether the mine roof has subsided, resulting in Hidden dangers cannot be discovered in time, which may cause harm to the lives of miners, so it is necessary to improve it

Abstract

The invention discloses a coal mining construction roadway temporary reinforcing device and a construction method thereof, and belongs to the field of mine supporting equipment. Comprising two hydraulic cylinders, two telescopic rods, a top plate I, a top plate II, four transmission devices I, four supporting devices, two connecting rods, a plurality of ropes and a transmission device II. The top plate I is fixedly connected to the upper ends of the two hydraulic cylinders; the transmission device I and the supporting device are arranged at the upper end of the top plate I, and the top plate II is arranged at the upper end of the transmission device I; the transmission device II is fixedly connected to the lower end of the top plate II, a plurality of ropes are arranged between the two supporting devices located in the middle, and the lower end of the transmission device II penetrates through the top plate I and is located at the upper ends of the ropes. Whether the top wall of a mine hole sinks or not can be detected through the transmission device I and the supporting device, so that timely maintenance or remediation is facilitated, and whether passing workers sink or not can be prompted through cooperation of the transmission device II and the rope.

Description

technical field [0001] The invention relates to a temporary reinforcement device for coal mining construction tunnels and a construction method thereof, belonging to the field of mine support equipment. Background technique [0002] In the process of coal mining, it is necessary to extend the mine tunnel and reinforce it to prevent collapse. Although the commonly used reinforcement device can prevent the mine tunnel from collapsing during use, it cannot detect whether the top wall of the mine cave is sinking, resulting in Hidden dangers cannot be discovered in time and may cause harm to the lives of miners, so it is necessary to improve them. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the background technology, and to provide a temporary reinforcement device for coal mining construction tunnels and a construction method thereof. [0004] The present invention achieves the above object, and th...
