Barrier-breaching jack for emergency rescue and disaster relief

Abstract

The invention discloses a barrier-breaching jack for emergency rescue and disaster relief, which relates to equipment special for escape and rescue. The barrier-breaching jack comprises support frames, connecting rods, a piston rod, a hydraulic cylinder, a one-way valve, a high-pressure hydraulic hose, a hydraulic pump and a pressure lever, and is characterized in that: the pressure lever and the piston type hydraulic pump form a hinge four-lever mechanism; the hydraulic pump is connected with the hydraulic cylinder by the high-pressure hose; the high-pressure hydraulic hose is provided with the one-way valve; the four support frames are connected together by rivets, and are inserted with the two connecting rods; and the hydraulic cylinder amplifying workload is connected with one end of each support frame by the piston rod and the connecting rods. As the support frames are driven by manpower to move by hydraulic transmission, the barrier-breaching jack is applied to the emergency rescue in natural disasters and when people are buried by large-area collapse caused by various accidents, can ensure the safety of rescuers and realize the expansion of a barrier-breaching area, is the equipment ensuring high rescue efficiency, and provides guarantee for the rescue under the adverse condition of downed power supply caused by catastrophes due to the manpower as power.

Description

technical field [0001] The invention relates to a special equipment for escape and rescue, in particular to a barrier-breaking facility that pushes manpower through hydraulic transmission to move a support frame, which is suitable for emergency rescue when natural disasters and various accidents cause large-scale landslides to bury people. Background technique [0002] At present, natural disasters and traffic accidents occur frequently, causing landslides of buildings and ground facilities and deformation of vehicles, causing trapped people to be buried or trapped in vehicles, which brings great inconvenience to rescue work. At present, the jacks used by rescuers have a small area of ​​obstacle removal and low rescue efficiency, and it is difficult for large-scale rescue facilities to reach the rescue site in time. It is difficult for many trapped people to be rescued in time, and death cases occur from time to time. In order to solve the above problems, it is imperative to...
