Description

Labor-saving type quick winding fire hose car capable of continuously and automatically draining water in subareas

Technical Field

The invention belongs to auxiliary equipment for fire control, and particularly relates to a labor-saving rapid winding fire hose car with continuous and automatic drainage subareas.

Background

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

Currently, fire-fighting forces are commonly equipped with 25m long in long-distance and high-rise water supplyOr->The water hose is mainly folded and bundled and folded and coiled; the folding binding type water hose winding and unwinding mode is that the water hose is placed on a fire engine after being wound, the water hose is easy to scatter along with jolt of the fire engine, the single-disc water hose is high in quality, carrying and laying of the water hose are not facilitated on a fire scene, unnecessary waste in time is caused, and the best opportunity for fire disaster suppression is wrong; the folding coiled water hose winding and unwinding mode has the advantages that after a disc of 25m water hose is wound, the space of an occupied equipment box is large, equipment is placed in disorder, 2 persons are needed to assist in long-distance carrying, the water hose is not easy to lay and easy to knot in throwing and laying, firefighters have low efficiency and slow unwinding during use, and the water hose is difficult to wind after use.

After the fire-fighting is completed, the fire fighter has great physical consumption, and the fire-fighting waterproof belt is rolled up quickly and in a labor-saving way, which is particularly important. The traditional mode of accomodating fire hose is that scene fire fighter adopts manual rolling. Because the fire hose is wet and long, and the fire fighter just performs fire fighting work, the winding of the fire hose is easy to consume the physical power of the fire fighter, and residual water in the fire hose is difficult to extrude, the wound fire hose becomes heavy, the burden is increased for subsequent transportation of the fire hose, the transportation efficiency is affected, and the fire fighting time is delayed. Therefore, when fire fighters roll up and store wet and long fire fighting water belts, and the fire fighting water belts are prone to have defects of insufficient rolling tightness caused by large residual moisture.

Chinese patent No. CN111632325 discloses a fire hose winding device, comprising a base plate, a first upright post and a second upright post are fixed on the base plate, a rotary round tube is connected with a bearing on the second upright post, a first baffle is fixed at the end of the rotary round tube, a central cylinder is arranged on the first baffle, a strip-shaped opening is arranged on the side wall of the central cylinder, and a driving component is arranged on the base plate; the first stand column is provided with a first supporting shaft and a second supporting shaft, the first supporting shaft and the second supporting shaft are respectively sleeved with a first rotating sleeve and a second rotating sleeve, the second supporting shaft is fixed on the side face of the first stand column, and the first stand column is also provided with a pressing component. This fire hose coiling mechanism passes through the hosepipe between first change cover and the second change cover to stretch into from the bar opening, make in the hosepipe head imbeds central section of thick bamboo, drive central section of thick bamboo through the motor and rotate, can the rolling hosepipe, utilize first change cover and second change cover extrusion hosepipe, can extrude the remaining water in the hosepipe. However, when the fire hose is wound, the wet-weight fire hose needs to be wound at the position of the winding device, so that the physical consumption of firefighters is increased, the time consumed by winding the fire hose is prolonged, the fire hose connector connected with the fire hose cannot pass through, only one fire hose is wound, the winding of the fire hose connected with a plurality of fire hose connectors cannot be operated, manual operation is needed, one fire hose connector cannot be wound, and manpower cannot be really liberated.

In addition, when the winding, the fire hose only remains a small amount of water, be platykurtic, the fire hose interface is the metal material, the fire hose interface protrusion, fire hose and fire hose interface are when the winding is on same book, very easily appear partial fire hose interface winding on the fire hose, but roll off the fire hose joint and roll up on another book when next fire hose is rolled up, take up with fire hose structure the winding that has appears, some slippage loosens, the high slip of fire hose and fire hose junction appears to low connection inclined plane, the condition such as fire hose rolling unevenness, indiscriminate book appear, the fire hose is blocked and is changeed not easily, or the state of being in a stack together in disorder influences fire hose rolling capacity, influence follow-up pull out fire hose use.

Therefore, how to thoroughly solve the problems that fire hose and fire hose joints cannot be continuously wound, fire hose drainage is incomplete, and fire hose cannot pass when being folded, synchronously realize that fire hose and fire hose joints are continuously wound, fire hose drainage and fire hose folding can also pass, and when automatically winding fire hose, labor-saving and rapid fire hose and interface partition winding are realized, so that the winding quantity and winding uniformity and regularity are improved, and the technical problem to be solved by the technicians in the field is solved urgently.
