What are the advantages of the crown wheel pad?
The crown wheel pad is used to prevent direct contact between the crown block and the steel wire rope, playing an important role in protecting the steel wire rope. The steel wire rope of a mine hoist rotates during operation. If the friction coefficient is too high, it will hinder the rotation of the steel wire rope and damage it. In this case, the wire rope must be guided into the shaft with minimal resistance to reduce torque and rotational stress. So what are the advantages of the crown wheel pad?
What are the advantages of the crown wheel pad?
1. The friction coefficient of the lining block is small and the wear resistance is good.
(1) When the wire rope runs, it will rotate. If the friction coefficient is too high, it will hinder the rotation of the steel wire rope and damage it. In this case, the wire rope must be introduced into the shaft with minimal resistance to reduce torque and rotational stress.
(2) The molecular orientation and crystal orientation of the lining material result in a smaller friction coefficient and lower wear resistance of the lining. When the steel wire rope rotates on the lining block, the frictional resistance is very small, and the torque generated by the rotation of the steel wire rope can be effectively released, thereby achieving the function of protecting the steel wire rope. The wheel lining block has special properties that allow the torsion and balance of the steel wire rope, good wear resistance, long service life, and saves costs for users, improving economic benefits.
2. The pads are self-lubricating and do not require oil, making them less prone to scaling.
It has good self-lubricating performance and is superior to other materials lubricated with oil, especially in harsh environments, dusty, and muddy areas. The dry lubrication performance of the product can be fully utilized. The pad not only allows for free operation, but also prevents adhesion and wear with the wire rope, thereby protecting the wire rope from wear or pulling.
What are the precautions after installing the crown wheel pad?
1. After a week of gasket repair, the gap should not exceed 0.2 millimeters according to the actual situation
2. When manually rotating the winch, leave a pair of installation positions for the sizing blocks and block them with half a pair to prevent the sizing blocks to be installed from falling off from the sizing block groove.
3. All construction personnel must operate with caution and obey the unified command of on-site leaders.
4. All construction personnel must wear safety helmets, fasten safety belts, and other labor protection equipment as required.
5. During the construction process, the safety belts of construction personnel must be securely fastened.
6. Special personnel should be responsible for the ground and separated by red warning lines. Non construction personnel are not allowed to pass under the mast.
7. Old mats should be packaged in snake skin bags to facilitate shipment. It is prohibited to throw old protective pads at will.
8. When manually turning, other personnel must stay away from the pulley to avoid accidents.
9. The communication signal between the pulley platform and the winch room must be kept clear.
10. During the construction process, all tools and instruments must be pulled and throwing is strictly prohibited.
11. If there are any unexpected situations during the construction process, the construction leader will provide unified command and solve them.
1. The transition block is suitable for single rope mine hoists, and is used when the steel wire rope is wound in more than one layer but less than four layers. If it is greater than four layers (including four layers), it is not applicable.MORE +
Since 2012, affected by factors such as declining market demand, lagging transformation and upgrading of the coal industry, and heavy tax burden and historical burden, the coal industry has experienced structural overcapacity, falling prices, corporate losses and other problems, which have made it more difficult to operate. In order to promote the smooth operation and sustainable and healthy development of the coal industry, with the consent of the State Council, the following opinions are hereby proposed:MORE +
