Underground quick supporting equipment set

Abstract

The invention relates to underground coal mine rescue devices, in particular to an underground quick supporting equipment set. The underground quick supporting equipment set has various combined supporting functions, greatly accelerates rescue, reduces workload for rescue teams and improves rescue efficiency; reinforced supporting of roadways in danger of collapse and collapsed objects in arbitrary underground landforms can be carried out; the underground quick supporting equipment set has certain uniformity, a complete set of parts including hydraulic lightweight struts, extension rods, end sockets and the like is universal and compatible and can be combined arbitrarily; uniform quick safety connectors are adopted for connection to meet the requirement on underground quick rescue; all adjustable devices of the equipment set adopt an acceleration valve technique, namely pistons stretch and retract fast before meeting with resistance, and operation efficiency is improved by about 35%; by cooperative use of the supporting equipment set, supporting speed is increased, and safety factor is increased.

Description

technical field [0001] The invention relates to an underground rescue device for coal mines, in particular to an underground fast complete support equipment. Background technique [0002] Disaster accidents such as underground gas (coal dust) explosion and roof fall are often accompanied by the collapse and blockage of the roadway, which seriously hinders the rescue work of the rescue team, and many accident cases show that the secondary collapse of the roadway after the accident The possibility is relatively large, which poses a serious threat to the personal safety of the rescue team, and also puts forward higher requirements for the grasp of the timing of rescue and the speed of rescue. In recent years, the experience and lessons of accident cases have shown that support speed and support quality directly affect the speed of opening rescue channels and rescue efficiency. [0003] In view of the current situation, it is very necessary to develop a device that can quickly ...
