Description
Technical Field
The utility model relates to a belt conveyor especially relates to a lower belt prevents off tracking device, belongs to colliery transport equipment technical field.
Background
Generally, due to the influence of the unevenness of an underground bottom plate, a belt of an underground belt conveyor deviates in the running process, particularly the lower belt deviates, the belt and an H frame are abraded mutually, so that the belt and the H frame are seriously abraded, the belt is narrowed after being abraded, and the conveying capacity is reduced; the H frame is broken after serious abrasion and needs to be stopped for replacement; the mutual friction and abrasion between the belt and the H frame seriously affect the underground production efficiency and increase the input of material cost of a transportation system; meanwhile, potential safety hazards of belt twisting exist in the process of overhauling and replacing the belt or the H frame, and casualties are caused.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: the lower belt deviation preventing device is characterized in that supporting plates are symmetrically mounted on an H-shaped frame, carrier rollers are arranged on the supporting plates in a shape like a Chinese character 'pin', the supporting rollers are respectively a compression roller and two carrier rollers, circular baffle discs are fixedly connected to two end faces of each carrier roller, a lower belt penetrates between the compression roller and the carrier rollers, the carrier rollers rotate along with the belt in the running process, the belt cannot be abraded, if deviation occurs, the lower belt can be blocked by the circular baffle discs at two ends of each carrier roller, the H-shaped frame cannot be abraded, meanwhile, the circular baffle discs and the carrier rollers are fixed together, the lower belt can rotate along with the rotating direction of the belt, and the belt cannot be abraded; the problems existing in the prior art are effectively solved.
The technical scheme of the utility model is that: the utility model provides a lower belt prevents off tracking device, it includes compression roller and bearing roller, has worn compression roller axle and bearing roller axle respectively on compression roller and bearing roller, the bearing roller is two left and right symmetric arrangements, and the compression roller is located the positive top of bearing roller and is article font structure, and fixedly connected with circle fender dish on the both ends face of bearing roller, the both ends of compression roller axle and bearing roller axle are equipped with the backup pad, have the clearance that holds the belt and pass between compression roller and bearing roller, and the circle keeps off the both ends that the dish is located the clearance.
One end of the supporting plate is provided with two lower grooves which are bilaterally symmetrical, the roller carrier shaft is positioned in the lower grooves, an upper groove is arranged above the middle of the lower grooves, the roller pressing shaft is positioned in the upper groove, and the other end of the supporting plate is provided with a bolt hole and is connected to the belt frame through a bolt.
The utility model has the advantages that: compared with the prior art, the technical scheme of the utility model is adopted, through the symmetrical installation backup pad on the H frame, the bearing roller is arranged in the shape of article' on the backup pad, be a compression roller and two bearing rollers respectively, fixedly connected with circle fender dish on the both ends face of bearing roller, the lower belt passes between compression roller and bearing roller, the bearing roller follows to rotate together in the belt operation process, can not cause wearing and tearing to the belt, if the off tracking appears, can be blocked by the circle fender dish at both ends on the bearing roller, can not grind the H frame, simultaneously circle fender dish is fixed together with the bearing roller, can follow the direction that the belt rotates and rotate together, can not cause wearing and tearing to the belt; the use effect is good.
