A sawtooth eliminating device for a trolley

Abstract

The invention relates to a trolley saw tooth eliminator which comprises a push tooth plate, a balancing weight and a rocker arm, wherein a first fixed hole is formed in one end of the rocker arm; a second fixed hole is formed in the other end of the rocker arm; the first fixed hole is fixedly connected with one end of a wire rope; the other end of the wire rope passes through a fixed pulley and is connected with the balancing weight; and the rocker arm is hinged with the push tooth plate through the second fixed hole. The trolley saw tooth eliminator is simple in structural design, and the trolley saw tooth phenomenon can be effectively eliminated.

Description

technical field [0001] The invention relates to the technical field of mechanical tensioning of sintering furnaces, in particular to a sawtooth eliminating device for a trolley, which can conveniently and quickly eliminate sawtooth of a trolley of a sintering machine. Background technique [0002] The sintering machine is one of the most important equipment for sintering production. At present, no matter the size of the tail swinging sintering machine used in China, when the trolley comes out from the rear return lane through the sprocket plate along the bend at the tail, due to the There is friction with the trolley workshop, resulting in different degrees of trolley sawtooth phenomenon, that is, the rear wheel of the trolley is lifted up, and cannot contact the lower track of the return lane. The sawtooth height generally ranges from 10 to 60mm. Hazards of trolley sawtooth phenomenon: (1) When the sawtooth trolley on the return lane runs to the head, due to the effect of ...

AI Technical Summary

Problems solved by technology

Hazards of trolley sawtooth phenomenon: (1) When the sawtooth trolley on the return lane runs to the head, due to the effect of its own weight or the drive of the head sprocket, the trolley gradually slides down, or falls instantly to produce an impact, causing the trolley Uneven wear at the end will reduce the service life of the trolley; it will cause damage to the bearing of the trolley and increase the consumption of spare parts; it will increase the air leakage rate of the sintering machine; at the same time, the impact force will have a greater impact on the steel structure of the sintering machine

(2) The trolley forms sawtooth in the tail curved rail, which produces uneven expansion force on the upper and lower rails of the tail exit curved rail, which accelerates the wear of the curved rail and reduces the service life of the curved rail; the uneven expansion force also causes the connecting curved rail Deformation and fracture of the steel structure, etc., become a frequent point of failure

(3) The trolley forms sawtooth in the curved rail at the tail, the trolley crawls, and the power consumption increases, which increases the load of the sintering machine and easily causes the tripping of the sintering machine

(4) The trolley forms sawtooth on the return lane, which causes the combination length of the upper sintering section trolley to be different from that of the lower return lane trolley, which causes the entire tail steel structure to be subjected to a large expansion force, and the entire mobile frame is swollen up and down Uneven force, in a tilted state, easy to cause the trolley to fall off the road, etc.

[0003] In the prior art, there is no special tool and method to eliminate the sawtooth phenomenon of the tail swing type sintering machine trolley
