What is a pneumatic winch, pneumatic winch manufacturer

Rudong Hongxin pneumatic winch is a kind of piston air motor as the power, manual operation or remote operation of the winch. It has the characteristics of high efficiency, easy operation, easy handling, safety and reliability. It can be used for lifting or consigning heavy loads in places such as land drilling, offshore drilling platforms, mine drilling, ships and flammable gases.

The pneumatic winch is powered by a vane air motor and transmits power to the drum to lift heavy objects through the planetary gear reducer. The motor and the reducer are respectively connected to the two sides of the drum, so that the winch is small in size, light in weight, compact in structure, simple in operation, convenient in maintenance, and can achieve stepless speed regulation within a certain range, and the braking of the winch is realized by the motor braking, and the braking is reliable. Manual operation is possible without compressed air.

Precautions when using pneumatic winch.

1. First the pneumatic motor, and then the transmission gear starts to run. Before starting, the brake belt on the drum should be braked first, and the brake lever on the big gear should be released, so that the drum does not rotate, and only the large internal gear rotates.

2. If you want to start the reel, first completely loosen the brake band on the drum, and then brake the brake band on the large internal gear. At this time, the drum rotates and winds the wire rope for work.

3. In the working process of the pneumatic winch, if the pneumatic winch is to be suspended, the brake belt of the large internal gear can be loosened, and then the brake belt on the drum can be braked.

4. When starting an electric vehicle, the two brakes cannot be braked at the same time, otherwise it is easy to cause the motor to burn.

5. The temperature of the reel brake belt and bearing of the pneumatic winch should not exceed 70, if the temperature rises sharply, stop the car immediately for inspection.

6. In order to prevent dust intrusion and lubricating oil overflow, the sealing device of the pneumatic winch is intact.

7. In order to ensure the operation, check whether the rope end of the winch is reliable before driving, whether the internal structure of the transmission is damaged or bitten, and whether the internal parts are overworn. Make sure that everything is correct before driving. In order to ensure operation, check whether the rope end of the winch is reliable before driving, whether the internal structure of the transmission is damaged or bitten, and whether the internal parts are overworn.

Winch, light and small lifting equipment that uses a drum to wind a wire rope or chain to lift or pull heavy objects, also known as a winch.

The winch can lift vertically, horizontally or tilt to pull heavy loads. There are two types of winches: manual winches and electric winches. Now it is dominated by electric winches.

It can be used alone, or it can be used as a component of machinery such as lifting, road construction and mine hoisting, and is widely used because of its simple operation, large amount of rope winding and convenient relocation. It is mainly used in construction, rock old water conservancy projects, forestry, mines, docks, etc.

Is a winch a winch

The main function of the winch and winch is to lift or drag the moving workpiece, and the name is different for different occasions; The pneumatic winch is mainly characterized by small power and small lifting load.

Now it is dominated by electric winches. It can be used alone, or it can be used as a component of machinery such as lifting, road construction and mine hoisting, and is widely used because of its simple operation, large amount of rope winding and convenient relocation. It is mainly used in construction, water conservancy engineering, forestry, mining, docks, etc.

1. Manual winch.

Manual winch, also known as hand-cranked winch, refers to a winch that uses manpower as the power to coarse and conceal the lift, and carries the resistance of the drum to rotate through the driving device.

2. Slow winch.

Slow speed winch is also called winch. Working principle: a device that drives the drum and winds the rope by human or mechanical power to complete the traction work. Simple lifting machinery for vertical lifting, horizontal or inclined traction of heavy loads. There are two types: manual and electric, mainly electric.

3. Small winch.

The small hoist, also known as the small hoist, is an electric crane dedicated to construction projects. The small winch model is DS type DT type. It has the characteristics of small size, light weight, heavy lifting, flexible operation, safety and reliability, and durability.

Pneumatic winch is a tool commonly used to lift or drag goods, which is easy to use and efficient, but it also needs to pay attention to the following points when using:

1.The operator needs to operate in strict accordance with the instruction manual and safety operation procedures, and cannot exceed the maximum load and maximum stroke range.

2.Before using the pneumatic winch, it is necessary to check whether the safety valve, brake and safety mechanism are in good working condition to ensure that the equipment is in a safe and complete state.

3.The pneumatic winch needs to use a clean air source and operate in accordance with the working pressure specified in the product manual to ensure the working efficiency and stability of the winch.

4.When starting, operating and stopping the winch, it should be smooth and slow, and should not start or stop suddenly, so as not to cause harm to the use environment and equipment.

5.When using pneumatic winches, it is necessary to select the appropriate winch lifting point, and ensure that the lifting devices and rigging used meet the standards and specifications to ensure the stability and safety of the suspended objects.

6.Regularly inspect and maintain the pneumatic winch, clean and lubricate the moving parts of the equipment, and ensure the normal operation and service life of the equipment.

7.After the work is completed, the pneumatic winch needs to be stopped and the lifting equipment needs to be dismantled, the equipment should be kept and cleaned and maintained in time.

To sum up, the correct and safe use of pneumatic winch requires choosing the appropriate pneumatic winch model, operating in strict accordance with the guidelines, paying attention to the safety and maintenance of the equipment, and also training employees in the skills and safe operation skills of the equipment.

1. The lifting force of the winch is insufficient, and the goods cannot be lifted.

The main reasons for the insufficient lifting force of the winch are: (1) the wear gap of the piston ring of the air motor is too large, resulting in accelerated gas leakage; (2)

The inlet pressure does not meet the specified requirements of the winch lifting; (3) The diameter of the gas supply pipe is not installed according to the specified requirements, the pipe diameter is too small, the air supply is insufficient and the pressure loss is too large. The general solution is to replace the piston ring and replace it with a suitable piston ring to adjust the wear room.

gap, increase the inlet pressure of the winch, through the calculation and the investigation of the site environment, according to the provisions of the correct air supply pipe diameter.

2. The winch is difficult to start and operate, and there is abnormal sound during operation.

When the winch is overhauled and installed, the piston connecting rod and housing are not cleanly assembled, and there are foreign bodies and impurities; The clutch did not follow the rules.

If there is a problem with the start of the winch, the air motor should be removed in time, cleaned again, and checked that there are no foreign objects.

Assemble; The wear gap between the small head and the big head of the connecting rod is too large, and the wear gap of the rolling bearing of the main journal of the crankshaft is too large.

If there is an abnormal sound in operation, replace the piston pin, crankshaft copper sleeve and ring, and replace the rolling bearing on the crankshaft main journal.

3 Lack of the right amount of lubricating oil in the body.

When the winch is in operation, various actuators and control elements require proper lubrication and run-in. If run.

The following faults will occur due to poor slippage: (1) the increase of friction resistance will lead to overheating of the air motor and the overload operation of the winch; (2) Sealing.

Material damage, resulting in grease leakage: (3) Insufficient grease or deterioration causes component damage, abnormal heating and operation failure. Lubrication.

The method generally adopts regularly adding lubricating oil to the air motor, and frequently unscrewing the oil drain plug to check whether the lubricating oil has deteriorated, such as.

If the oil is found to have deteriorated or mixed with water, it should be replaced immediately; Check the lubricating oil in the lubricator and find that it is not should be replaced immediately.

Spray lubrication for the lubricator is generally installed after the filter and pressure reducing valve, which is the guarantee of the operation of the body. Also ask regularly.

Add lubricating oil to the gear transmission part and each oil nozzle to ensure the normal operation of the gear.

4. Poor sealing of pneumatic system.

Air leakage in the pneumatic system not only increases the loss of energy, but also leads to a decrease in the supply pressure, and even causes pneumatic elements.

The work fails, which eventually leads to the failure of the winch operation; The system should be inspected regularly with the instrument.

5. The working pressure and movement speed of the pneumatic device are improper.

When adjusting the working pressure, the pressure gauge should read accurately. After the regulator and throttle valve are adjusted, the regulator cover or lock needs to be tightened.

Tighten the nut to prevent loosening, air leakage, and affect the running speed.

Winches can be divided into four types: manual winch, electric winch, pneumatic winch, and hydraulic winch according to their different usage methods.

A winch is a light and small lifting equipment (see hoisting machinery) that uses a drum to wind a wire rope or chain to lift or pull heavy objects, also known as a winch. The winch can be used alone, or it can be used as a component of machinery such as lifting, road construction and mine hoisting, and is widely used because of its simple operation, large amount of rope winding, and convenient relocation. The winch is also known as the winch.

The product has high versatility, compact structure, small size, light weight, heavy lifting, easy use and transfer, and is widely used in construction, water conservancy engineering, forestry, mining, wharf, etc.

The hydraulic winch is mainly a winch with a large rated load, and the winch from more than 10t to 5000t is generally designed as a hydraulic winch.

The working principle of hydraulic transmission uses oil as the working medium, transmits movement through the change of sealing volume, and transmits power through the pressure inside the oil.

1. The power part converts the mechanical energy of the prime mover into the pressure energy (hydraulic energy) of the oil. For example: hydraulic pumps.

2. The execution part converts the oil pressure energy input from the hydraulic pump into the mechanical energy of the driving mechanism. For example: hydraulic cylinders, hydraulic motors.

3. The control part is used to control and adjust the pressure, flow and flow direction of the oil. Examples: pressure control valves, flow control valves, and directional control valves

4. The auxiliary part connects the first three parts together to form a system, which plays the role of oil storage, filtration, measurement and sealing. For example: pipes and fittings, fuel tanks, filters, accumulators, seals and control instruments.

The pressure exerted at any point on a certain volume of liquid can be transmitted in all directions in equal magnitude. This means that when multiple cylinders are used, each cylinder will pull or push at its own speed, and these speeds depend on the pressure required to move the load.

In the case of the same range of hydraulic cylinder carrying capacity, the hydraulic cylinder carrying the smallest load will move first, and the hydraulic cylinder carrying the largest load will move last.

In order for the cylinders to move synchronously so that the load is jacked at the same speed at any point, it is important to use a control valve or a synchronous jacking system element in the system.
