Abstract
The invention relates to a tunnel collapse life saving machine. The tunnel collapse life saving machine comprises a diameter-varying cutting head, a screw conveying shaft, a screw conveying shaft rotation drive device, a life-saving barrel, a propulsion system, a hydraulic pump station, a base plate, a power distribution cabinet and a control cabinet, wherein the screw conveying shaft is sleeved in the life-saving barrel. According to the life saving machine, the diameter-varying cutting head is used for cutting collapsed soil bodies in a manner of breaking rock; the excavation diameter can be timely adjusted in the propulsion process; cut muck is discharged form the rear end of the life-saving barrel through the screw conveying shaft; the life-saving barrel is propelled along with the propulsion of the screw conveying shaft; when the screw conveying shaft is drawn out, the life-saving barrel forms a safe passage, so that personnel trapped by collapse in the tunneling process can be quickly and safely rescued in a human-friendly manner; meanwhile, the screw conveying shaft and the life-saving barrel in the life saving machine consist of a plurality of sections, are lengthened in a manner of changing steps and facilitate long distance excavation; and a steel wire rope is used for tensioning the front end of the screw conveying shaft, so that the downwarping of the screw conveying shaft is reduced, and the normal work is ensured.
Description
technical field [0001] The invention belongs to the field of machinery, in particular to rescue equipment, in particular to a tunnel collapse lifesaving machine. Background technique [0002] During the excavation of tunnels, landslides sometimes occur suddenly due to geological reasons. If the landslide occurs behind the workers on the excavation surface of the tunnel, the passage between the workers and the back of the tunnel may be cut off, and they will be in a state of lack of oxygen, drinking water and food. If there are injured people, they will also be in a dangerous situation because they cannot receive timely medical treatment. The traditional method of carrying out emergency rescue to the trapped people is to adopt engineering machinery such as excavators, loaders, multi-functional drilling rigs, rock drills to carry out rescue or drill holes and shoot. Due to the large earthwork workload, large soil disturbance and the possibility of partial blasting, there are...
