[0002] The hoisting roller device of the coking plant coke intercepting car is installed on the upper part of the coke guide grid. It plays the role of supporting the weight of the coke guide grid and realizing the forward and backward movement of the coke guide grid. It is a key part of the coke guide grid.

[0003] The existing hanging roller device generally includes a roller shaft, a wheel body, an end cover and a bearing installed between the roller shaft and the wheel body. A cover is provided at one end of the outer side of the wheel body to protect the bearing. During use, the hanging roller bears a weight of about 30 tons when the coke grid is full of coke. During operation, the hanging roller is in long-term contact with the guide rail, and the surface of the wheel body will be worn. When the wear value of the outer surface of the wheel body drops to a certain extent, the cover on the outer side of the hanging roller will directly contact the rail surface, which may easily cause the cover to fall off. After the cover falls off, coke powder will easily enter the bearing, causing damage to the bearing, and the coke intercepting car cannot operate normally, which will affect production.
