Breaking and dismantling device for rescue

Abstract

A breaking and dismantling device for rescue comprises a barrier breaking puncher pin. The barrier breaking puncher pin is mounted at one end tip of an impacting rod 2, and the other end of the impacting rod penetrates through a guide bush and is connected with an eccentric steel ball. The guide bush is fixed at one end of a sleeve, and the eccentric steel ball is connected with a check ring through an impacting needle and a return spring which is arranged on the impacting needle in a sleeved mode. The check ring is mounted on one side of an impacting block, and the other side of the impacting block is connected with the bottom of a spring route adjusting rear cover through a force application spring. The spring route adjusting rear cover is connected with one end of the sleeve. The eccentric steel ball, the return spring, the impacting needle, the check ring, the impacting block and the force application spring are located in the sleeve. The spring route adjusting rear cover is mounted on a handle which is connected with a gun stock. When the breaking and dismantling device for the rescue is used, the handle on the spring route adjusting rear cover is held, the barrier breaking puncher pin abuts against a masonry barrier to be broken and is pushed forward to compress the springs, and after being compressed to certain distances, the springs are released abruptly to generate large enough impact force which can break through the masonry barrier. The breaking and dismantling device for the rescue has the advantages of being capable of being operated manually, convenient to carry and use, high in efficiency and capable of being used in all directions.

Description

technical field [0001] The invention relates to the technical field of rescue devices, in particular to a rescue and demolition device. Background technique [0002] Traditional rescue and demolition tools include crowbars, rescue axes, shovels, and iron picks. It is laborious and inefficient to use, and can no longer meet the needs of search and rescue of collapsed urban structures. In recent years, several portable manual small-scale rescue equipment have been developed, each with its own advantages and disadvantages. Among them, manual hydraulic rescue and demolition tools are the main ones. There are several manual hydraulic rescue and rescue tools such as shears, combined hydraulic tools, jacks, etc., which are driven by manual cylinders, easy to carry and use, and high in efficiency. However, the sealing problem of hydraulic oil has not been solved. Therefore, Work reliability is poor. There are also several manual hydraulic rescue tools such as hydraulic pliers, e...

AI Technical Summary

Problems solved by technology

There are several manual hydraulic rescue and rescue tools such as shears, combined hydraulic tools, jacks, etc., which are driven by manual cylinders, easy to carry and use, and high in efficiency. However, the sealing problem of hydraulic oil has not been solved. Therefore, Work reliability is poor

There are also several manual hydraulic rescue tools such as hydraulic pliers, expanders, shears, hydraulic diamond chain saws, hydraulic breaking picks, etc., which are powerful and efficient, but need to be connected to a hydraulic pump station driven by an internal combustion engine, which is bulky , relatively bulky, inconvenient to carry

To sum up, the existing portable manual small-scale rescue equipment has many disadvantages and cannot meet the needs of on-site rescue
