Tail wheel regulating device of novel bucket elevator

Abstract

The invention discloses a tail wheel regulating device of a novel bucket elevator, and belongs to the mechanical technical filed of bucket elevators. The tail wheel regulating device comprises a base,a pressure plate and standing plates, wherein a slide block is arranged between the adjacent standing plates, a bearing base is arranged at the inner side of the slide block, the upper end of the bearing base is fixedly equipped with a connecting pin roll, the upper end of the connecting pin roll is connected with a regulating lead screw, the outer ring of the regulating lead screw is further assembled with regulating nuts and spring pads in a spaced mode; a spring is arranged between adjacent spring pads; the inner side of the bearing base is separately equipped with a bearing and a tightening shaft; and the middle part of the tightening shaft is equipped with a tightening wheel. According to the tail wheel regulating device disclosed by the invention, the tightening shaft is lengthened,so that the bearing base is separated from a box body, the bearing base has a relatively great operation space for enabling the bearing base to move up and down, and the two sides of the bearing basecan perpendicularly move under action of the slide block, and therefore, the purposes of buffering and regulating are achieved; and the tightening wheel is liable to dismount, and is convenient to replace, so that in practical operation, a fault rate is low, and maintenance is easy.

Description

technical field [0001] The invention relates to the technical field of bucket elevators, and more specifically, relates to a novel tail wheel adjustment device for bucket elevators. Background technique [0002] The main function of the bucket elevator is to lift and transport the semi-finished pellets concentrated in the ash hopper to the feed trough of the rotary kiln. The temperature of the transported lump ore and particles is ≥700°, and the high temperature can easily cause the chain links of the bucket elevator to expand, elongate and twist when heated, and the chain bucket is deformed, so that the running chain will run off the track and the deformed chain bucket will scrape the box , In severe cases, the chain bucket will fall off, the tail wheel will tilt, the bearing and the bearing seat will be damaged, and the tightening screw will bend, causing the bucket elevator to overload and stop, and it will not operate normally. The original design of the bucket elevator ...

AI Technical Summary

Problems solved by technology

The temperature of the transported lump ore and particles is ≥700°, and the high temperature can easily cause the chain links of the bucket elevator to expand, elongate and twist when heated, and the chain bucket is deformed, so that the running chain will run off the track and the deformed chain bucket will scrape the box , In severe cases, the chain bucket will fall off, the tail wheel will tilt, the bearing and the bearing seat will be damaged, and the tightening screw will bend, causing the bucket elevator to overload and stop, and it will not operate normally. The original design of the bucket elevator tail wheel assembly is through the bearing The lifting lug on the sealing plate of the seat is rigidly connected with the box body by a screw rod, which can only play the role of positioning and tensioning in the initial stage

The elongation of the chain belt during operation cannot be adjusted in time, resulting in the failure of the chain belt to run along the centerline of the head and tail wheels

During the daily inspection, it was found that the elongation of the chain belt can only be adjusted manually through the tightness of the bolts. The operation is cumbersome, the reliability is not strong, and it is too dependent on human factors.

The assembly form of the tail wheel and the shaft is an interference fit, and it is difficult to replace the tail wheel after it is worn out. Only the whole assembly of the tail wheel can be off-line and outsourced for repair, which increases the maintenance cost
