Cylinders For Transfer Machines

Cylinder for self-movement is a key part of coal mine machinery and equipment for realising the equipment moving forward by itself, which provides thrust for the equipment through hydraulic transmission principle, so that the equipment can move along the pre-set track or slideway.

Cylinder for self-movement is a key part of coal mine machinery and equipment for realising the equipment moving forward by itself, which provides thrust for the equipment through hydraulic transmission principle, so that the equipment can move along the pre-set track or slideway. The following is a detailed analysis of the cylinder for self-moving:

1. Definition and function

Definition: the cylinder for self-movement is a device that generates thrust through hydraulic transmission, which is installed on the equipment that needs to move forward on its own, such as transfer machine, crusher, etc., and the expansion and contraction of the cylinder is controlled to realise the movement of the equipment.

Function:

1. Thrust generation: through the hydraulic transmission system, the cylinder can generate enough thrust to overcome the resistance and friction encountered by the equipment in the process of pushing.

2. Precise control: through the control valve and other hydraulic components, you can accurately control the cylinder expansion and contraction speed and the size of the thrust, to achieve the smooth movement of the equipment.

3. Strong adaptability: the cylinder for self-movement is suitable for different inclination angles and working surfaces of the trench environment, to meet the needs of different equipment to move.

2. Structure and composition

The structure and composition of the cylinder may vary depending on the manufacturer and the specific model, but generally speaking, it mainly includes the following parts:

- Cylinder block: the main part of the cylinder, usually made of high-strength steel, with sufficient load-bearing capacity and sealing performance.

- Piston: It is located inside the cylinder body and connected to the outside of the cylinder through the piston rod. The movement of the piston will change the pressure and volume of the oil in the cylinder, thus generating thrust.

- Piston rod: the part connecting the piston and the outside of the cylinder, used to transmit thrust. The material and size of the piston rod should be designed according to the specific needs to ensure its carrying capacity and stability.

- Seal: installed between the cylinder and piston, used to prevent oil leakage and impurities into the cylinder. The performance of seals directly affects the efficiency and life of the cylinder.

- Hydraulic transmission system: including hydraulic pump station, control valves, hydraulic piping and other components, used to provide power for the cylinder and control its action.

3. Principle of operation

The working principle of the cylinder is based on the hydraulic transmission principle. When the hydraulic pump station to the cylinder oil supply, oil in the control valve group under the action of a chamber into the cylinder (high pressure chamber), so that the chamber pressure rises and push the piston to move. The movement of the piston is transmitted to the equipment through the piston rod, so that the equipment produces a push action. At the same time, the oil in the other chamber (low-pressure chamber) flows back to the tank through the control valve group, forming a pressure difference and a flow difference, thus driving the equipment to move continuously. Through the switching and adjustment of the control valve group, precise control of the cylinder expansion and contraction speed and thrust size can be achieved.

4. Application and Maintenance

Application:

The cylinder for stepping self-movement is widely used in the high-productivity and high-efficiency working face of coal mines, especially for the self-movement forward mechanism of the transfer machine, crusher and other equipments. It can significantly improve the pushing efficiency and operation safety of the equipment, reduce the manual intervention and downtime, so as to improve the productivity and economic benefits of the whole working face.

Maintenance:

1. regularly check the sealing performance of the cylinder and the working condition of the hydraulic transmission system, and timely replace the damaged seals and repair the faulty hydraulic components.

2. Clean the debris and coal dust on the surface of the cylinder to keep it clean and dry.

3. check whether the fixing bolts and connecting parts of the cylinder are firm and reliable to prevent them from loosening or falling off in the course of operation.

4. lubricate and maintain the cylinder regularly to prolong its service life and keep its performance stable.

5. Caution

- When installing and using the cylinder for stepping self-transfer, it should be operated in strict accordance with the operation regulations to ensure safe production.

- Select the appropriate cylinder type and specification to meet the actual production requirements.

- Enhance the maintenance and repair work of the oil cylinder to detect and deal with potential problems and faults in time.

Please note that the above information is based on an overview of general conditions and common practices. In actual applications, the specific design and maintenance requirements of cylinders for stride self-transfer may vary depending on the equipment model, manufacturer, and the environment in which they are used. Therefore, the technical manuals and maintenance guides of the relevant equipment should be consulted for specific operations.
