Description

Fire hose transmission structure for winding fire hose

Technical Field

The invention belongs to the technical field of fire fighting, and particularly relates to a drainage transmission structure for rolling a fire hose.

Background

The fire hose is a hose for conveying high-pressure water, foam and other flame-retardant liquids, the traditional fire hose takes rubber as a lining, the outer surface of the traditional fire hose is wrapped by linen, the advanced fire hose is made of polyurethane and other polymeric materials, metal connectors are arranged at two ends of the fire hose, and the fire hose can be connected with another hose to prolong the distance or connected with a nozzle to increase the liquid injection pressure.

After fire fighting is finished, the fire-fighting water belt needs to be rolled. The traditional mode of accomodating fire hose is that on-the-spot fire fighter adopts manual rolling. Because the fire hose is wet again long, and the fire fighter has just carried out the work of putting out a fire of fighting fire again, the rolling of fire hose consumes the physical power of fire fighter easily, and is difficult to extrude the remaining water in the fire hose, and the fire hose after the rolling becomes heavy, for follow-up transportation fire hose increases burden, influences handling efficiency, delays the time of fire control. It is obvious that, when the fire fighter how realizes rolling up the fire hose of wet again long and accomodate to and the fire hose easily remains more moisture and leads to the not enough and heavy defect of the inseparable degree of rolling.

The invention discloses a fire hose winding device which comprises a bottom plate, wherein a first upright post and a second upright post are fixed on the bottom plate, a rotating circular pipe is connected to a bearing on the second upright post, a first baffle plate is fixed at the end part of the rotating circular pipe, a central cylinder is arranged on the first baffle plate, a strip-shaped opening is formed in the side wall of the central cylinder, and a driving assembly is arranged on the bottom plate; be equipped with first stay axle and second stay axle on the first stand, the cover is equipped with first commentaries on classics cover and second commentaries on classics cover on first stay axle and the second stay axle respectively, and the second props the axle and fixes on the side of first stand, still is equipped with down the subassembly on the first stand. This fire hose coiling mechanism is through changeing the hosepipe and passing between the cover from first commentaries on classics cover and second to stretch into from the bar opening, make in the hosepipe head embedding center section of thick bamboo, through the rotation of motor drive center section of thick bamboo, can the rolling hosepipe, utilize first commentaries on classics cover and second to change the cover extrusion hosepipe, can extrude away remaining water in the hosepipe. However, it can't realize that the fire hose joint of connecting the fire hose passes through, only rolls one section of fire hose, to the rolling of the fire hose of a plurality of fire hose coupling connections, just can't operate, needs manual operation, and one section is collected, can't really liberate the manpower.

Therefore, how thoroughly solve the problem that fire hose and fire hose joint can't roll in succession, fire hose drainage is not thorough, fire hose can't pass through when folding, realize simultaneously that fire hose and fire hose joint roll in succession, fire hose drainage, fire hose are folding also can pass through, is the technical problem that the field technical staff awaits a urgent need to solve.
