Belt redirection roller online repair device and method

Abstract

The invention provides a belt redirection roller online repair device and method. The belt redirection roller online repair device comprises a turning mechanism and a base. The turning mechanism comprises a rack, a transmission screw and a turning tool. A tool rest is composed of a nut, a pressing plate and fixing bolts. The turning tool is fixed into a nut tool slot through the pressing plate and the fixing bolts. The two end walls of the box-shaped rack are provided with screw holes, the outer sides of the screw holes are each connected with a fixing plate with a bearing, and the two sides of the transmission screw are installed in the bearings. The nut located in the rack is arranged on the transmission screw in an engaged manner, and one end of the transmission screw is provided with a rocking handle. The inner side in the operation direction of a redirection roller belt is provided with the base and the rack, the turning tool is fixed through the pressing plate and the fixing bolts after being adjusted, a belt machine is started, after a redirection roller is driven to rotate steadily, the rocking handle is shaken, and the turning tool is fed through a spiral pair to perform turning on a protruding cast rubber layer on one side of the redirection roller. By means of the belt redirection roller online repair device and method, online repair of the redirection roller can be achieved, the phenomenon of belt deviation is prevented, the service life of the redirection roller is prolonged by more than two times, machine halt and halt production time is saved, the repair time is shortened, and the number of maintenance persons is reduced.

Description

technical field [0001] The invention belongs to the field of machining, and in particular relates to an online repair device and a repair method for a belt deflection roller of a belt conveyor. Background technique [0002] The belt conveyor is the basic equipment for the continuous conveying of materials in large-scale enterprises. Belt deviation is a common fault in the actual use of the belt conveyor. If the belt deviation is not corrected in time, it will affect the normal operation of the belt or scratch the belt, causing greater losses. There are many reasons for the deviation of the belt, among which the belt deviation caused by the wear of the cylindrical working surface of the redirecting roller at the tail of the belt machine is one of the main reasons, and this deviation phenomenon is difficult to adjust. So far, there is no effective , Practical and simple repair method. Meet this kind of situation and can only be forced to shut down in advance or stop producti...

If the belt deviation is not corrected in time, it will affect the normal operation of the belt or scratch the belt, resulting in greater losses

There are many reasons for the deviation of the belt, among which the belt deviation caused by the wear of the cylindrical working surface of the redirecting roller at the tail of the belt machine is one of the main reasons, and this deviation phenomenon is difficult to adjust. So far, there is no effective , practical and simple repair method

In case of such a situation, we can only be forced to stop in advance or stop production to replace the redirecting roller, which greatly reduces the service life of the redirecting roller, causes great waste, and increases the consumption of spare parts and expenses

[0003] At present, the redirecting roller of the belt conveyor generally adopts the surface cast rubber structure, and the thickness of the cast rubber layer is generally 12-15mm. After long-term use, it is found that the wear of the cast rubber layer of the redirecting roller is from the middle of the redirecting roller. The working part with the most contact friction with the belt begins. When the thickness of the middle cast rubber layer is worn off by 5-6mm, the belt will start to deviate. Deviation intensified
