the backrest mechanism comprises a backrest frame, the backrest frame consists of a frame type top plate, a frame type bottom plate and support upright posts positioned at four corners between the frame type top plate and the frame type bottom plate, the top end surface and the left end surface of the backrest frame are respectively provided with a backrest baffle, and a bucket of the excavator is tightly attached to the backrest baffle;
the jacking mechanism comprises two door-shaped steel frames distributed left and right, I-shaped steel is arranged at the front end and the rear end of the top end of each door-shaped steel frame, the two ends of each I-shaped steel are located on the outer sides of the two door-shaped steel frames, inclined struts fixed with the front end of each I-shaped steel and the middle part of the door-shaped steel frame vertical rod on the right side are arranged between the front end of each I-shaped steel and the middle part of the door-shaped steel frame vertical rod on the right side, square steel pipes are arranged at the front end and the rear end of the bottom end of each door-shaped steel frame, hydraulic jacks which are horizontally fixed on the left door-shaped steel frame vertical rod and vertically distributed and are in contact with the backrest frame right end supporting upright post, jacking baffles are arranged on the upper end face and the front end face and.
The rescue equipment utilizes a hydraulic pump station to drive a hydraulic jack to extend, a backrest mechanism provides a reaction force, the whole pushing mechanism is pushed to advance, the soil is continuously removed in the pushing process, then the operation space on the left side of the pushing mechanism is supported, the above procedures are continuously repeated, and finally a small pilot tunnel channel is formed to rescue out trapped people.
When the collapse-preventing device works, the collapse body is subjected to back pressure reinforcement before the small guide pit is excavated, then a proper excavation position is selected, the excavator bucket teeth are used for propping against the back backrest, the hydraulic pump station is started, and four jacks are jacked on the backrest frame to reversely push the whole jacking mechanism to advance in a stepping mode and are inserted into the collapse body; in the pushing process, a short shovel, a triangular rake, a rubber dustpan and other small tools are used for continuously discharging soil in the pushing mechanism manually; when the hydraulic jack is completely extended out, the hydraulic jack is stopped and retracted, and a certain space is generated between the left end of the jacking mechanism and the backrest mechanism for supporting to form a small pilot tunnel channel; starting the hydraulic pump station again, enabling the hydraulic jack to extend out to be jacked on the small pilot tunnel, enabling the reverse pushing jacking mechanism to continue to advance and be inserted into the collapse body, and enabling people to continuously come out of the soil in the jacking process; the above procedures are repeated continuously until the jacking mechanism jacks through the collapsed square body to form an escape channel, and the rescued people are rescued. The tunnel construction rescue device solves the problems that the existing tunnel construction rescue device is easy to collapse, low in construction precision, high in safety risk, low in efficiency and serious in waste.
At least one pit guiding wood box frame is arranged between the backrest mechanism and the jacking mechanism, and the pit guiding wood box frame consists of an upper top plate, a lower bottom plate and a vertical square wood upright post positioned between the upper top plate and the lower bottom plate.
In the space that produces between top mechanism left end and the back mechanism, utilize and lead the pit wood box frame and strut fixedly, stability can obtain further promotion.
Inclined struts I are arranged between the front end and the rear end of the I-shaped steel and the door-shaped steel frame ejector rods adjacent to the I-shaped steel.
The structural design further improves the rigidity of the rescue equipment, and the safety performance is further improved.
The utility model has the advantages of reasonable design reliably, can be fast laborsaving insert the body of collapsing, the efficiency of construction is promoted by a wide margin, adopts little pilot hole excavation to reduce the disturbance to the soil body on every side moreover, and stability can be higher, and then has stopped the emergence of potential safety hazard, and it is higher to execute the precision of doing, has simple structure, convenient operation's advantage with low costs.
