Abstract

The invention discloses a pulling tool of a high-pressure fire-fighting hose. The pulling tool comprises a first transverse connecting rod, a second transverse connecting rod and grips, wherein each grip comprises a supporting connecting rod, a pulling connecting rod and a pulling claw; two ends of the supporting connecting rods are movably connected with one end of the first transverse connecting rod and one end of the pulling connecting rods respectively; the other ends of the pulling connecting rods are connected with the pulling claws; two ends of the second transverse connecting rod are movably connected with the pulling connecting rods at two sides respectively; a guide rod is arranged at the bottom of the first transverse connecting rod; the guide rod is arranged in a guide hole in the second transverse connecting rod in a penetrating manner and can slide in the guide hole along the length direction of the the guide rod; a longitudinal handle and a transverse handle are arranged on the first transverse connecting rod and the second transverse connecting rod respectively. The pulling tool of the high-pressure fire-fighting hose, disclosed by the invention, is light and compact in structure and safe and reliable in working, and can be used for rapidly and effectively clamping and putting down the fire-fighting hose, so that the working intensity of fire-fighters is greatly alleviated and the fire-fighting working efficiency is improved.

Description

technical field [0001] The invention relates to the field of auxiliary equipment for fire-fighting operations, in particular to a traction tool for a high-pressure fire-fighting hose. Background technique [0002] At present, fire fighters mainly rely on firefighters to clamp the high-pressure fire hose under their armpits in actual fire drills and firefighting scenes. Run while tugging on the hose to straighten it. This is a method of completely relying on manpower to complete firefighting operations, which consumes a lot of physical energy for fire fighters, and the method of relying on hand grasping and armpit clamping is not reliable. Traditional high-pressure fire hoses generally use Type 94 high-pressure fire hoses. According to calculations, the weight of a high-pressure fire hose with an outer diameter of 94 mm and a length of 20 meters is 5 kg, and the weight of the hose filled with water is about 128 kg. , The total weight of the high-pressure fire hose reaches a...
