Standards and requirements for the application of overhead wheel linersin early winterHeavenly WheelAccording to the provisions of the "Safety Regulations for Metal and Non-metallic Mines", the rim of the wheel must be higher than the wire rope, and the size of the higher part should be greater than 15 times. This regulation is to ensure that the wheel can effectively carry the wire rope during use and prevent it from wearing out in contact with the wheel rim. At the same time, when the padded overhead wheel is installed, the liner should be tightly fixed on the overhead wheel to increase its stability and durability.
Install or replace the linersWhen installing or replacing the liners, the relevant standards must be strictly observed. The axial and radial dimensions of the liner should be slightly larger than the size of the mounting groove to create a certain amount of interference to ensure that the liner is tightly seated in the mounting groove. This interference can effectively reduce the vibration and displacement of the liner during operation, and improve the stability of the wheel of the wheel.
The radial thickness of the linerThe radial thickness h of the liner should be equal to the sum of the diameter of the wire rope and the thickness of the liner before replacement. This setting minimizes the variation of the wire rope lifting center, thereby reducing the wear and tear of the tank track and its guide groove during use. This extends the service life of the tank and guide troughs and ensures the safe operation of the mining equipment.
Suitable paddingChoosing the right upholstery material and thickness is key. The right liner material and thickness can keep the position of the rope lift center unchanged or minimal, thus reducing wear on the tank track and guide trough. At the same time, it also extends the service life of the wheel and reduces maintenance and replacement costs.
Groove depth and radiusThe thickness of the liner and the depth and radius of the rope groove are the key technical parameters for optimization. The selection of these parameters directly affects the performance and life of the wheel. Therefore, these parameters must be considered and optimized in detail when designing and selecting the wheel of the sky.
Groove radiusAccording to the experience of Tongxing company, when the depth of the rope groove is about 25% of the diameter of the wire rope, the use requirements can be met. The reasonable radius of the rope groove should make the wire rope and the bottom of the groove closely adhere and maintain the necessary clearance. According to the experimental data, it is a reasonable choice to take the rope groove radius to 55% of the diameter of the wire rope.
The material of the liner linerWhen choosing the material of the wheel liner, you can choose the appropriate material according to the use environment and working conditions. For example, PVC, polyurethane or ultra-high molecular weight polyethylene are commonly used liner materials. These materials have good wear resistance, corrosion resistance and impact resistance, and can adapt to the harsh working environment of mining equipment.
