Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic breaking and demolition devices, in particular to a pneumatic breaking and demolition device for port fire fighting. Background Art

[0002] Pneumatic cutting knives are mainly used by firefighters, traffic police, and armed police forces in the event of fire, earthquake, car accident, or assault rescue. They can quickly demolish and remove obstacles such as anti-theft window railings, collapsed building steel bars, and window bars. In port firefighting, in order to ensure the fire safety of the port, a commonly used pneumatic demolition device is a pneumatic cutting knife. Pneumatic cutting knives are used in traffic rescue, emergency departments, firefighters, traffic police, and armed police forces in the event of fire, earthquake, car accident, or assault rescue. They can quickly demolish anti-theft doors and cars involved in accidents, and are especially suitable for special occasions such as no power supply.

[0003] However, in actual use, when the existing pneumatic cutters are used for port firefighting and demolition, firefighters sometimes need to climb to a higher position to use the pneumatic cutters to demolish obstacles such as building steel bars and window bars. When demolishing obstacles such as building steel bars and window bars, it is sometimes necessary to use multiple tools to cooperate with each other to achieve the demolition purpose. When switching tools, the firefighters are in a higher position and cannot temporarily place the pneumatic cutters on the ground. Therefore, most of them need to hold the pneumatic cutters, which is not convenient for switching between multiple tools and affects the demolition progress of firefighters. Therefore, it is necessary to design and modify the pneumatic demolition device for port firefighting to solve the problem that it is difficult to place at high places. Utility Model Content
