Four-prop shield bracket is a device that uses a hydraulic cylinder to adjust the support height and provide support for coal mining industries such as coal mines. The following is a detailed introduction to the four-column shield support and its related jacks and columns:
1. Four-column shield support
Compared with the traditional two-column structure, the four-column structure shielded hydraulic support is simple to maintain and has higher stability, which can significantly improve coal mining efficiency and safety.
2. Push Jack
A push jack is a common mechanical tool used to lift and move heavy objects. In a four-post shield support, the push jack may be used to push the support itself or other components on the support. The selection of push jacks needs to consider factors such as load, stroke, and working environment.
3. Bottom lifting jack
The bottom lifting jack is a double-acting hydraulic cylinder. In the coal mining face, the bottom plate is relatively soft and has been blistered for a long time, which can easily cause the support base to sink or the support to hit the bottom when moving the frame, so that the support cannot move forward. At this time, the role of the bottom lifting jack is to lift the front end of the base before moving the frame, so that the support can be moved easily.
4. Telescopic beam jack
The telescopic beam jack is used to adjust the length and position of the telescopic beam to adapt to different coal mining faces and support requirements. The telescopic beam jack has a variety of specifications and models, which can be selected according to actual needs.
5. Protection jack
The protection jack is a common type of jack. Compared with ordinary jacks, it has a wider range of applications and higher safety. Guard jacks are suitable for many fields, including vehicle maintenance, construction engineering, shipbuilding, etc. In the four-column shield support, the guard jack may be used to support and protect the coal wall or the side of the tunnel.
6. Hydraulic prop
The columns are the main working mechanism of the hydraulic support, which is used to make the hydraulic support bear the top plate load and adjust the support height. The columns are the pressure-bearing components of the support and are under high pressure for a long time. In addition to having reasonable working resistance and reliable working characteristics, they must also have sufficient compressive and bending strength and good sealing performance.
In the four-column shield support, the number and specifications of the columns have an important influence on the bearing capacity and stability of the support. Therefore, when selecting and using the columns, it is necessary to consider the actual work needs and safety requirements.
In summary, the four-column shield support and its related jacks and columns play an important role in coal mining industries such as coal mines. When selecting and using these equipment, it is necessary to fully consider the actual work needs and safety requirements to ensure the reliability and stability of the equipment.
