Description

A hydraulic expander for fire emergency

technical field

The invention relates to the technical field of fire emergency tools, in particular to a hydraulic expander for fire emergency.

Background technique

Fire protection is to eliminate hidden dangers, and disaster prevention is to prevent and solve man-made, natural and accidental disasters that people encounter in the process of life, work and study. There are many types of fire-fighting tools, and a fire emergency hydraulic expander is one of them. The hydraulic expander is an emergency rescue tool with expansion, tearing and pulling functions. It is made of high-strength light alloy steel and can be used for high-load rescue operations. However, there are many defects in the use of hydraulic expanders. When the expander is in use, it needs to be lifted by firefighters. Once the operation time is too long, the physical strength of the firefighters will be particularly serious, which will directly affect the progress of the work. When the door railing is expanded, the railing will break under the action of external force. At the same time, due to the smooth surface of the railing, the expansion arm and the railing cannot be fixed, resulting in problems such as slipping and flying off the railing, which is difficult for the staff to operate and personal. Safety affects, so we propose a hydraulic expander for fire emergency.
