A warning device for coal mining
ActiveCN224281087UIncrease the percussion areafix fixityTraffic signalsRoad signsMining engineeringStructural engineering
This utility model provides a warning device for coal mining, relating to the technical field of auxiliary equipment for coal mines. It includes a base with a warning cylinder fixedly connected to its top. The top of the warning cylinder has a piercing hole that penetrates the bottom of the base. This utility model allows a positioning cone rod, penetrating the piercing hole, to move vertically up and down along the warning cylinder, piercing into the soil or coal seam for positioning. Simultaneously, a pressure block fixedly connected to the top of the positioning cone rod increases the striking area, facilitating downward displacement of the positioning cone rod by striking the pressure block with a tool, further penetrating the soil or coal seam. A prying groove at the bottom of the pressure block allows a pry bar to be inserted, expanding the distance between the pressure block and the top of the warning cylinder, thus detaching the positioning cone rod from the soil or coal seam. This solves the problems of inconvenient fixing and difficult disassembly of existing warning devices.
