Abstract

The invention discloses a handheld cutting gun used for cold cutting firefighting. The handheld cutting gun can serve as a vehicle-mounted movable cutting tool and is especially important for a rescue vehicle needed on an affected field. The handheld cutting gun is connected with an ultrahigh-pressure water source arranged on the rescue vehicle through an ultrahigh-pressure hose. The handheld cutting gun used for cold cutting firefighting can be moved to the position near a cut object. Supplied ultrahigh-pressure water is sprayed out through a spraying opening of a gun head assembly. Under the strong negative-pressure effect of the ultrahigh-pressure water, abrasives are sprayed out together with the ultrahigh-pressure water through an abrasive connecting opening, and the cut object is cut. A button sends a signal to a radio receiving device on the vehicle through a radio transmission device, and an ultrahigh-pressure water source provides or cuts off the ultrahigh-pressure water. An arranged scram button is used for cutting off the ultrahigh-pressure water under emergencies so as to ensure safe operation. A cover arranged at the front end of the button is used for preventing the phenomenon that the cutting work is started due to careless pressing of the button. Due to the arrangement of an ultrahigh-pressure hose, the moving range of the cutting gun is enlarged.

Description

Technical field [0001] The invention belongs to the technical field of water jets, and particularly relates to a hand-held cutting gun for cold cutting and fire fighting. Background technique [0002] The application range of water jets is very wide, from metal materials to non-metal materials, from natural materials to artificial materials, from food to daily necessities, basically can cut, and has the reputation of "universal cutting machine". The main application areas are: ceramics, stone and other building materials processing; glass product processing, such as glass parts cutting in home appliances, architectural decoration, and craft glass; metal sheet cutting in the machinery industry; cutting of signs and artistic patterns in the advertising industry. The advantages of waterjet cutting are highly versatile, and almost all materials can be cut; the waterjet is cold cutting, which does not produce thermal effects, deformation, slag, or ablation during cutting, and will not...
