Tool for demolishing by using energy of blank cartridge

Abstract

The invention discloses a tool for demolishing by using the energy of a blank cartridge, comprising a launcher and a punching and shearing assembly which are connected with each other, wherein the launcher is of a rifle bolt type firing structure and comprises a grip, a non-in-place insurance, a firing mechanism, a cartridge receiver, a rifle bolt assembly, a magazine, a launch tube, a pressure adjusting assembly and a non-in-place insurance spring. The non-in-place insurance serving as an L-shaped assembly is located above the firing mechanism; the long edge of the L-shaped assembly is located in a guide rail of the cartridge receiver and moves backwards under the driving of the rifle bolt assembly to relieve insurance; the short edge of the L-shaped assembly is connected with the cartridge receiver through the non-in-place insurance spring and resets under the action of the non-in-place insurance spring to open the insurance; and the pressure adjusting assembly is located above the launching tube fixedly connected with the cartridge receiver. The problem of demolishing steel bars, steel slings, blots, door locks and the like by utilizing the tool for demolishing by using the energy of a blank cartridge is solved, and the tool has powerful energy and is capable of effectively shearing a screw-thread steel bar with the diameter of 16mm and a steel wire rope with the diameter of 11mm.

Description

technical field [0001] The invention belongs to the technical field of demolition tools, in particular to a bullet-energy demolition tool for powerfully cutting or demolishing obstacles. Background technique [0002] Existing rescue tools and equipment (rescue equipment) can be divided into manual rescue tools, electric rescue tools, motorized rescue tools, hydraulic rescue tools, pneumatic rescue tools, bullet energy rescue tools, Other demolition tools. Other rescue tools: gas cutting, non-sparking tools, etc., suitable for special rescue places. The bullet energy demolition tool uses the high-pressure gas generated by the explosion of the ammunition as the power source, and has the advantages of small equipment size and high efficiency. [0003] The currently used bullet-energy demolition tools mainly include: lock-breaking guns, dual-power door rams, bullet pliers, etc., which are widely used in public security, fire-fighting, and armed police departments. However, th...

Problems solved by technology

However, there is no in-place safety, that is, the ammunition must be locked in place before firing, otherwise it cannot be fired reliably. The in-place safety is a device that ensures that the ammunition is released when the lock is in place through the mechanical structure, so as to ensure reliable firing.

There is no in-place insurance so that the operator does not know the locking status of the ammunition, and there will be abnormal situations such as invalid firing, misfire, and jamming.
