Crane horizontal wheel mechanism capable of adjusting clearance

Abstract

The invention provides a crane horizontal wheel mechanism capable of adjusting a clearance. The crane horizontal wheel mechanism comprises a horizontal wheel body, a bearing, bearing end covers, a shaft sleeve, woodruff keys and an eccentric shaft, wherein one end of the horizontal wheel body is connected with the eccentric shaft, the bearing is arranged between the horizontal wheel body and the eccentric shaft, the shaft sleeve is arranged between the bearing and the horizontal wheel body, the bearing end covers are respectively arranged on both ends of the bearing, the two bearing end covers are fixedly connected with the horizontal wheel body, and the inner circular surfaces of the two bearing end covers are connected with a bearing pressing cover in an extrusion way. According to the crane horizontal wheel mechanism capable of adjusting the clearance, the clearance between a horizontal wheel and a rail can be compensated without replacing the horizontal wheel, so as to satisfy the normal guide requirement of the rail.

Description

technical field [0001] The invention relates to a horizontal wheel mechanism of a crane with adjustable clearance, which belongs to the technical field of machinery. Background technique [0002] The position of the horizontal wheel of the existing crane is fixed, and the gap between it and the track is a fixed value. After the water has been used for a period of time, due to the friction between the horizontal wheel and the track, the gap between the horizontal wheel and the track will increase, which cannot meet the guiding requirements. Only by replacing the new horizontal wheel can the guiding purpose be met. At the same time, when the horizontal wheel is subjected to an abnormally large horizontal force, it does not have a buffering effect, which will cause deformation and damage to the horizontal wheel shaft. Contents of the invention [0003] The invention provides a crane horizontal wheel mechanism with adjustable gap, which can compensate the gap between the hori...

AI Technical Summary

Problems solved by technology

After using the water for a period of time, due to the friction between the horizontal wheel and the track, the gap between the horizontal wheel and the track will increase, which cannot meet the guiding requirements. Only by replacing the new horizontal wheel can the guiding purpose be met.

At the same time, when the horizontal wheel is subjected to an abnormally large horizontal force, it does not have a buffering effect, which will cause deformation and damage to the horizontal wheel shaft.
