The main function of the connecting head of the hydraulic support is to connect the scraper conveyor and the hydraulic support organically to realize the effect of force transmission between them.
When working, the connecting head has to move the bracket and push the conveyor to carry out the operation, and the organic operation of these two links should be completed. Therefore, in addition to the alternating stress of tension, compression and torsion, and the poor working environment in the mine, and the heavy humidity in the air, there may be many unexpected factors, leading to the deterioration of the stress of the joint head. Once the connection is damaged, the scraper conveyor and hydraulic support may not work normally, and may be shut down and stop production, causing huge losses. Therefore, the hydraulic support connection head also plays an important role in coal mine production.

The hydraulic support connector is also quite common in the daily procurement of hydraulic support parts. Its main function is to connect scraper conveyor and hydraulic support organically to realize the role of force transmission between them. When working, the connecting head has to move the bracket and push the conveyor to carry out the operation, completing the organic operation of these two links. When the hydraulic support connector works under the alternating stress of tension, compression and torsion, if the working environment in the mine is poor and the air is humid, there may be many unexpected factors, leading to the deterioration of the stress of the connector. Once the connection is damaged, the scraper conveyor and hydraulic support may not work normally, which may be shut down and stop production, causing huge losses. Therefore, it is necessary to check the first vulnerable parts of the hydraulic support connection from time to time, so as to avoid production problems.

The hydraulic support connector is a vulnerable part. After the casting was used, the forging process was changed because the strength could not meet the requirements. Today, I have a preliminary understanding of the processing technology of the hydraulic support connector. At first, the free forging process was adopted, and later it was changed to gas cutting forming. Due to the limited forging tonnage, the blank margin produced by forging has a large rough edge, and the forming ability of semicircle ball is poor. Later, after improvement, it can save materials and man-hour, simple operation, high production efficiency, flexible process operation, and local forming. As the main connecting part of hydraulic support, the connecting head is easy to wear out, so it has high requirements on material technology. On the one hand, it can improve the service life and then reduce the maintenance and replacement cost. If you need hydraulic support connector, please contact us
The hydraulic prop is the main component to support and carry the hydraulic support, it directly affects the performance of the hydraulic support. Therefore, in addition to reasonable working resistance and reliable working characteristics, hydraulic prop must also have enough compressive and bending strength, good sealing performance, simple structure and suitable for the work of hydraulic support needs. Hydraulic prop is generally composed of piston, piston rod, cylinder block three parts. Because the support work, the column bearing capacity is large, and the drop column force is small, so the piston rod diameter is larger, often use hollow structure, in order to ensure sufficient stiffness of the piston is generally y sealing ring, copper ring guide, cylinder bottom welding. The cylinder block and the cylinder head are connected by steel wire, thread or clasp. In order to prevent the external coal seam and other stolen goods into the cylinder block, the guide sleeve should be equipped with a dustproof ring. For the single telescopic column, in order to expand the support height of the hydraulic support, can use mechanical extension rod, the head structure of the column is spherical, and the connection between the top beam or the base with pin shaft or block fixed, in order to make the column in the work by a certain adaptability. The liquid supply method of hydraulic prop consists of two ways: internal liquid supply and external liquid supply. In addition to the double telescopic column with internal liquid supply mode, the single telescopic column is mostly external liquid supply mode, which is simple in structure, convenient in processing and maintenance.

Fixed protection, such as wooden brackets, shall be applied in the delivery and transportation of y303-30 hydraulic support columns. In case of large quantities, such as hydraulic jacks, which are delivered in batches, shall be bundled firmly to avoid falling off, extrusion, rolling collision and other damages. If it is in winter, the product should be injected with antifreeze according to the low temperature of the applicable area and the transportation distance. In other seasons, the emulsion in the column of Y303-30 hydraulic support should be emptied. However, the transportation and storage process of the column after the drainage should be guaranteed, and no corrosion phenomenon should occur inside. If the hydraulic support column of Y303-30 has been stored for more than three months, the emulsion in the hydraulic support column should be checked for deterioration. If so, the emulsion should be replaced. When the drainage method is adopted, the rust should be checked. The hydraulic support column of Y303-30 should be paid attention to and ensure that the joint seat is not damaged during the use, and the transportation package should be strong and reliable. The column should be loaded and unloaded lightly in the process of transportation. Special attention should be paid to the joint seat so as not to damage the interface and affect the connection use of the hydraulic support column. In fact, the above methods are not only for y303-30 hydraulic support column, but also for all kinds of hydraulic support jack cylinders. In transportation, storage and use, some problems can be avoided for the hydraulic support column or hydraulic support jack. Henan Shuangzhi Machinery as hydraulic support accessories manufacturers, can produce and process hydraulic support column, hydraulic support jack, bed beam, bed, bottom adjustment beam and other accessories, welcome new and old customers to consult understanding, looking forward to working with you!
