Underground quick supporting equipment set

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
