Hydraulic winch is used in all kinds of lifting equipment. The type of industrial hydraulic winch is divided into: internal type hydraulic hoist, exposed hydraulic winch, high speed hydraulic hoist, low speed hydraulic hoist, etc. Hydraulic winch usually consists of hydraulic motor, control valve group, gearbox, drum, bracket, (clutch), pressure rope or rope, mounting bracket and so on. Some hydraulic winches are not equipped with supports, which are composed of hydraulic motors, control valves, drums, and end support shafts, which can be selected according to the needs of customers.
The use of industrial hydraulic winch
Industrial hydraulic winch is widely used for conveying equipment, engineering machinery hoisting machinery, such as mobile crane, crawler crane, overhead working truck, crane, forestry and the port of ship class such as port crane, floating crane ship, dredger, lifting capacity, davit, and can be used in large hoisting equipment such as oil rigs, offshore oil drilling platform, pile driving machinery rotating drill, drill rig, core drilling machine, hydro-static pressure pile machine and so on.
The type of industrial hydraulic winch
Based on capacity, industrial hydraulic winch can be divided into small winch and large winch.
small hydraulic winch
The small hoist is a special electric crane for construction projects. The model of small winch is DS type \DT. It has the characteristics of small size, light weight, big operation, flexible operation, safe and reliable and durable. They are mainly used for lifting heavy, pull, push, drag, applicable to buildings, bridges, metallurgy, mining companies such as site, materials used for lifting large projects and dragging a variety of materials and equipment.
large hydraulic winch
The large hydraulic winch can be used alone, and it can also be used for lifting, building roads and lifting of mines. They are widely used because of its simple operation, large amount of rope and convenient displacement. It is mainly used in building, hydraulic engineering, forestry, mining, wharf, etc. Speaking of a large hydraulic winch, it refers to a device normally made of metal, applied to lift and pull something with larger quantity. There are different tonnages of winch machines to meet different requirement and conditions. Therefore, the suitable and reliable one should be selected to guarantee efficient, reliable and safe lifting and pulling operations.
Winch rope of industrial hydraulic winch
The type of winch rope is divided into four categories. Because the winch rope has these following characteristics: portable-carrying, convenient maintenance and good chemical resistance, and light weight, high strength, not easy to damage the lifting surfaces and so on. It is more and more popular with the use of personnel and gradually takes the place of steel wire rope in many ways. They are increasingly used in the modern, technological, international hoisting construction site. And they are widely used in steel mills, oil fields, ports, and transportation industries.
Therefore, the maintenance method of the winch rope of industrial hydraulic winch is very important.
1. Don’t drag and drop the winch rope when lifting or pulling something;
2. The winch rope shall not be connected with any device that may cause damage or wear to it;
3. When carrying, it should not be twisted;
4. The winch rope with no sheath shall not be used to carry the goods with sharp corners and edges;
5. Should avoid winch rope opening angle exceeds 20 °;
6. Since the winch rope should be kept under the condition of avoiding light and ultraviolet radiation, industrial hydraulic winch should also be kept in the required place;
7. The winch rope should not be taken near fire or other heat sources;
8. When not using the winch rope, place the sling in the place where the light is good, etc.
The noise control of industrial hydraulic winch
National transportation infrastructure, the scale of urban construction is more and more big, the hoist used in the construction scale, the power is more and more big, then drawing is becoming more and more fast, accordingly, the key to hoist reel open gear transmission devices vice structure size bigger. In the case of high power and high speed, the noise of the hoist is higher and higher. Yet this is not allowed by national standards.
The national standard of the building hoist national standard GB1955-2002 stipulates that the noise limit of the qualified hoist shall not be greater than 85DB(A) and the operator’s ear must not be greater than 88DB(A). When the traction of the hoist is smaller and the speed is lower, the noise is far lower than the standard limit, and it is easy to control. However, when the traction speed is high and the traction force is large, it is necessary to ensure that the noise is not excessive, and effective measures should be taken from the design, process, materials, quality inspection and other links.
Using oil as the working medium, the movement is transmitted through the change of the sealing volume, and the power is transmitted through the internal pressure of the oil.
The working principle of industrial hydraulic winch
1. Power part – the mechanical energy of the original motive can be converted into hydraulic pressure energy (hydraulic energy), for example: hydraulic pump.
2. The execution part – the hydraulic pressure of the hydraulic pump can be converted into the mechanical energy of the working mechanism.
For example: hydraulic cylinder, hydraulic motor.
3. Control part – to control and adjust the pressure, flow and flow direction of the oil, such as pressure control valve, flow control valve and directional control valve.
4. Auxiliary parts – connect the first three parts together to form a system, which can be used for oil storage, filtration, measurement and sealing.
For example: pipes and joints, fuel tanks, filters, accumulators, seals and control instruments, etc.
Any point on a certain volume of liquid pressure, to equal in all directions. This means that when using more than one hydraulic cylinder, the speed of each hydraulic cylinder will be effected according to the pull or push, the movement depends on the speed load the required pressure.
