Problems solved by technology

[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 high, which poses a serious threat to the personal safety of the rescue team, and also puts forward higher requirements for the timing of rescue and the speed of rescue.

Embodiment Construction

[0040] Specific technical parameters of the rapid complete set of support equipment described in the present invention

[0041] ①Hydraulic portable prop

[0042] The hydraulic portable prop is an adjustable part of the complete set of support equipment. It adopts a quick coupling system and can be connected or disassembled with other equipment within 1 second. There is an automatic locking device, which can realize quick support when the support rod needs to be placed in an unsafe area. The hydraulic portable strut also adopts the acceleration valve technology, which increases the speed of piston expansion and contraction before encountering resistance, which can increase the working efficiency by about 35%. Automatic locking device is prior known technology, has multiple structures and can realize.

[0043] Technical parameters of hydraulic portable prop:

[0044] 1000mm hydraulic portable prop: working pressure 720bar, shrinkage length 1035mm, stroke 252mm, weight 11.9kg,...

Abstract

The invention relates to an underground rescue device for coal mines, in particular to an underground fast complete support equipment. The complete set of fast underground support equipment has a variety of combined support functions, which greatly speeds up the rescue speed, reduces the workload of the rescuers, and improves the rescue efficiency; The roadway is reinforced and supported; the complete set of support equipment has a certain degree of unity, and all components such as the complete set of hydraulic portable props, extension rods and ends are universally compatible and can be combined arbitrarily; Rescue requirements; all adjustable devices of the whole set of equipment use the acceleration valve technology, that is, the piston retracts faster before encountering resistance, and the work efficiency is increased by about 35%; the complete set of support equipment is used in conjunction with each other to increase the support speed , increasing the safety factor.

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 ...
