Handcart type fire hose recovery device

Abstract

The invention relates to a handcart type fire hose recovery device, belonging to the technical field of fire-fighting equipment and comprising a base, a water hose joint fork, a travelling mechanism, a manual traction mechanism and a transmission mechanism, wherein the water hose joint fork is provided with a joint fork shaft, is rotatably arranged on the base by the joint fork shaft and is positioned on one side of the upper end of the base; the travelling mechanism is fixedly connected with the bottom of the base; the manual traction mechanism is equipped on the base; the transmission mechanism consists of a first transmission wheel, a second transmission wheel and a transmission belt and is used for driving the water hose joint fork to rotate; the first transmission wheel is fixed on the joint fork shaft; the second transmission wheel is fixedly arranged on the travelling mechanism; and one end of the transmission belt is sheathed on the first transmission wheel, and the other end of the transmission belt is sheathed on the second transmission wheel. The handcart type fire hose recovery device has the advantages of being capable of reducing the working intensity of fire fighters, avoiding the loosing or spinning phenomenon, and having simple whole structure, labor-saving movement and no condition that the water hose generates resistance to water in the hose reeling process.

Description

technical field [0001] The invention belongs to the technical field of fire fighting equipment, and in particular relates to a handcart type fire hose recovery device. Background technique [0002] The function of the fire hose is self-evident. It is equipped on fire trucks or emergency rescue vehicles. Deliver water. Take firefighting as an example, when it is put into use, it is laid by firefighters, and after the firefighting is over, it is also recycled into rolls by firefighters or neatly folded by means of a fire hose folding device such as the utility model authorization announcement number CN2843536Y. In standby state, but most of them are stored in roll form in standby state. Undoubtedly, the lengthy fire hoses of tens, hundreds or even thousands of meters appear in the form of rolls (also called discs), which have a rolling effect when they are laid, which can increase the speed of laying to win valuable Even if it is the disaster relief time of every minute and...

Problems solved by technology

However, the process of reeling the lengthy fire hose into rolls is usually done manually by firefighters, which is labor-intensive and inefficient

[0003] The fire hose retractor recommended by utility model authorization announcement number CN12684872Y can make up for the lack of high work intensity and low efficiency of firefighters caused by manual retraction of fire hoses

But this patent scheme still has the following defects: one is that there is not enough to fully reduce the work intensity of the firefighters when taking in the tape, because the firefighters need to operate the handle to rotate the winding core of the winding and unwinding mechanism when taking in the tape to make the fire hose Coiled on the winding core; second, the structure is more complicated, and the use is more troublesome. For details, please refer to page 2 of the patent specification

[0004] Compared with CN2684872Y, the portable fire hose reel recommended by the authorized announcement number CN26026610Y has the advantages of simple structure, but it also needs to rely on the manual handle of the firefighters to rotate the reel shaft, so the firefighters still need to consume a lot of physical strength , in particular, the solution is easy to fall during use because it cannot be temporarily fixed with the fire truck body, that is to say, because the stability of the base recommended by the solution is difficult to guarantee, it is difficult to be used by firefighters during the take-up process. The pedaling force of the feet helps to stabilize, but as a result, the uniformity of the two sides of the fire hose disc (roll) that is folded into a roll will be poor, and even a gyro phenomenon will appear.

[0005] The fire hose reel introduced by the authorized announcement number CN2032481U also has the shortcomings of the above two patents, that is, it is not enough to ideally reduce the work intensity of firefighters.

In addition, in this patent solution, there are many transition links where the hose is wound on the hose shaft, which increases the resistance of the hose recovery, makes the operation of the firefighters more laborious, and it is difficult to turn the head of the hose at the beginning of the take-up. Positioning, so that the hose head is located outside the roll shape, there is a risk that the hose core roll will come out of the core
