Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a lifting device for fire fighting and extinguishing. Background Art

[0002] Firefighting equipment commonly includes fire hoses, the ends of which are connected to fire sprinklers. Firefighters lay fire hoses near the fire and then inject high-pressure water into the fire hoses, which are then ejected through the fire sprinklers to the ignition area, thereby achieving the purpose of extinguishing the fire.

[0003] After the fire sprinkler sprays high-pressure water, a reaction force will be generated. This reaction force will cause the fire sprinkler to produce a relative thrust. This thrust requires firefighters to hold the fire sprinkler tightly to offset it, so as to prevent the fire sprinkler from moving backwards due to the reaction force. This process will greatly consume the physical strength of the firefighters.

[0008] Since the above-mentioned lifting equipment itself needs to have a certain weight in order to offset the reaction force well, and the fire scene is complicated, the position of the water spraying often needs to be changed. In this process, it is inconvenient to carry the lifting equipment, so its use scenario is single and its applicability is poor. Utility Model Content
