Description

water pulley

The invention relates to a water pulley, in particular to a device for assisting in the maneuvering of at least one fire hose or pressurized hose, which can maintain safety and can be easily maneuvered on any type of ground, and can be used when necessary A device for carrying multiple hoses.

When a fire occurs, the fixed point for firefighters to go is usually defined and given by the command post; when the fire truck is positioned, the firefighters unfold the hoses from their respective brackets and connect the nozzles to the hoses so that the firefighters can It can be used to dispense water with or without additives in the form of a spray, depending on the nozzle type.

The required length of the hose is deployed by the responsible fire fighters based on on-site conditions. A rough estimate is that the diameter of the hose hose generally ranges from 45mm to 110mm. These hoses are made of soft materials, so they can be rolled flat when stored. They allow them to be maneuvered around objects along the terrain; at the same time, these hoses are also made of complex fabrics, so they have a certain degree of strength and can withstand high pressure, heat resistance and fire resistance.

The other end of the hose is designed to be connected to a pressurized water supply produced by a pump or known means and driven by a fire engine engine or auxiliary device, or to a fire hydrant connected to a high pressure system.

When a hose is ready for use, once pressure is applied, the hose takes on a circular profile due to the radial pressure exerted on the inside of the hose; this pressure is maintained due to the counter-pressure exerted at the outlet end of the hose, The diameter of the outlet end of the hose will be smaller than the diameter of the hose.

Because high pressure will make the hose stronger and more difficult to operate, especially when the length of the hose is extended, it will be more difficult to operate. The difficulty in operation is related to the stiffness of the hose under pressure on the one hand, and to the water on the other hand. It is related to the weight of the hose; the weight of the hose will have two consequences, one is to give important inherent weight, making it difficult to lift the hose, and the other is to exert important support on the ground due to the weight of the hose itself, which will cause High friction.

It can be seen that when there are many natural obstacles such as bushes, gravels, branches, etc. on the ground, or in the woods or rubble in urban areas, firefighters need to exert considerable effort, and sometimes even have to exceed one or more of them. the physical strength of the firefighter; in either case this is unsatisfactory because, in the first case, the firefighter's strength is exhausted to the detriment of the physical strength required for the rest of the operation, or, in the second case, the person is Being redeployed to the detriment of other personnel's functions.

It should be noted that in some operating situations, such as in the petroleum or chemical industries, equipment may be away for long periods of time; therefore, assistance in pulling such hoses is necessary, and this is confirmed as the diameter of the hose increases , far exceeding the diameter used in traditional urban operations.

It is well known that hose control assist/moving devices severely limit the maneuverability of the hose; such devices consist of a bracket capable of receiving half of the force of the hose in its mid-section and is provided with Clamping devices help maintain and clamp the hose in the carriage, which is equipped with rolling devices that help move the device; however, these devices have clamping devices that are complex and slow to implement.

The purpose of this creation is to improve the above-mentioned shortcomings in order to provide a device that can maintain safety and can be easily maneuvered on any type of ground, and can carry multiple hoses when necessary.

In order to achieve the above purpose, the water pulley of this invention includes a frame, which is provided with at least one bracket, and the frame is also provided with a shifting device; the bracket has a circular groove, and its opening is directed upward. Preferably, the circular groove is an arc extending over 180 degrees; The circular groove of the bracket has a lower semicircle. The bracket extends to both sides along the lower semicircle to form extension parts. The ends of the two extension parts form free ends respectively; and the distance between the two free ends is smaller than the water belt. diameter; in order to fix the hose in place in the bracket; The two free ends are formed to face each other, and the two free ends are slightly protruding from a plane tangent to the level of the diameter end point of the lower semicircle; Through the above structure, a device that can maintain safety and can be easily maneuvered on any type of ground is provided, and can carry multiple hoses when necessary.
