Description

Detachable H frame bearing roller supports and holds in palm ear

Technical Field

The utility model relates to a belt conveyor technical field especially relates to a detachable H frame bearing roller supports and holds in palm ear.

Background

Belt belt conveyor belt H frame bearing roller support and hold in the palm ear wearing and tearing or drop and cause the bearing roller to lose the effect and make the belt off tracking easily at operation in-process belt H frame bearing roller, and the belt off tracking is the most common trouble among the band conveyor operation process, and its harm nature is very big, and the main influence has following several aspects: the belt deviation causes system fault shutdown to influence the production operation efficiency. When the belt off tracking reaches a certain degree, the belt can trigger an emergency stop device for preventing the belt from off tracking, so that the operation system is stopped, and the production process is influenced. Causing abnormal damage to the major components of the equipment. Firstly, the belt deviates to increase the axial force borne by the roller and the carrier roller, so that the roller shaft is broken and the carrier roller bearing is damaged; secondly, the belt deviates to cause the materials to be sprinkled onto the return belt, so that the belt and the roller are abnormally abraded, and the service life of the roller and the belt is shortened; in addition, the off tracking belt generates abnormal friction with the support when in operation, so that the edge of the belt is abraded, and the service life of the belt is influenced. Potential safety hazards are easily formed. The belt is seriously deviated, so that the belt is turned over and materials are coiled, the stress on one side of the belt exceeds the longitudinal tensile force of the belt, and the potential safety hazards of transverse tearing of the belt and the like are caused. The environment is polluted, and the quality of conveyed materials is influenced. Coal dust is often caused in the process of material scattering and cleaning, and the environment is polluted; meanwhile, the quality of conveyed goods is also affected by the scattering of materials. Therefore, in the actual operation process, the belt deviation not only greatly damages the belt conveyor, but also has the problems of potential safety hazard, influence on the production efficiency, the quality of conveyed goods, environmental pollution and the like. Therefore, we propose a detachable H-frame idler support lug.
