Detailed Description
The invention aims to improve the dismounting and mounting efficiency of the hopper and reduce the forced downtime of a production line.
The bucket elevator is the name of a whole set of system, wherein a steel wire rubber belt is conveying equipment, hoppers are fixedly arranged on the steel wire rubber belt through bolts, and the distance between the two hoppers is 150 mm. The fixture is formed by reversely buckling two channel steels together, punching holes in the channel steels, penetrating the two channel steels and the steel wire adhesive tapes by bolts, and fastening and clamping the steel wire adhesive tapes. The bucket elevator is a shell surrounded by four external surfaces, and cutting holes are 1.2 x 1.5m square holes and are positioned on the conveying surface of the steel wire adhesive tape and the shells on two side surfaces.
A speed reducer with a non-return function is selected (MC 3RLHF07, the speed ratio 48.9626 and the maximum reverse torque is 34.2KN.m in the invention), (a motor of the bucket elevator is connected with the speed reducer through a hydraulic coupler to drive a roller, the inner side of a steel wire adhesive tape covers the roller and is driven to operate through friction, the reverse force is 34.2KN.m, the capacity is matched with the design load of the whole set of equipment, the speed reducer cannot be adjusted, and the speed reducer only stops when one side of the speed reducer is prevented from being heavier by the reverse torque), and a clamp is used for clamping the middle steel wire adhesive tape position of a hopper at the cutting hole of a platform at the lower layer of a head wheel to support the hopper on a shell of the bucket elevator from the bottom of the hopper so as to avoid rotating in the reverse direction.
3-5 hoppers are firstly removed from the forward rotating side of a head wheel of the bucket elevator, a speed reducer is kept under a reverse force, and the hoppers are synchronously removed from diagonal cutting holes of a platform on the lower layer of the head wheel and a tail wheel, so that the hoppers are removed in sequence. When the material hopper is reloaded, 3-5 material hoppers are firstly arranged in the reverse direction of the tail wheel, then the diagonal operation is carried out at the cutting holes of the head wheel and the tail wheel, and the material hoppers are arranged in sequence.
