Problems solved by technology
[0002] Firefighting is to eliminate hidden dangers, and disaster prevention is the general term for preventing and solving the man-made, natural and accidental disasters that people encounter in their life, work and study. There are many kinds of firefighting tools, and a hydraulic expander for firefighting emergency is one of them. One, hydraulic expander, is an emergency rescue tool with the functions of expansion, tearing and pulling. It is made of high-strength light alloy steel and can perform high-load rescue operations. The expander needs to be lifted by firefighters when it is in use. Once the operation time is too long, the physical exertion 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 sliding down the railing and flying, which is difficult for the staff to operate and personally Safety is affected, so we propose a hydraulic expander for fire emergency

The invention discloses a hydraulic expander for fire emergency, relates to the technical field of fire emergency tools, in particular to a hydraulic expander for fire emergency, comprising a hydraulic mechanism body and an auxiliary electric hydraulic rod. The fire emergency hydraulic expander is used in conjunction with the auxiliary sleeve plate, the limit plate, the cylinder limit groove and the cutting blade. The cylinder limit groove on the surface of the cover board fixes railing objects, which not only prevents the expansion arm from sliding on the railing, but also prevents the railing from breaking and flying after being stressed, which improves the hydraulic expansion of the fire emergency. At the same time, by installing a cutting blade on the inner side of the expansion arm, when operating a relatively dense railing, the cutting blade can be used to cut the railing, thereby expanding the passage, and improving the function of the fire emergency hydraulic expander sex.
