Turning guide device for upper beam of stacker

Abstract

A turning guide device for the upper beam of a stacker, including a guide wheel bracket, a rotating frame, and three guide wheels, the guide wheel bracket is fixed at both ends of the upper beam, and the rotating frame is fixed on the guide wheel bracket through a rotating shaft Above, the rotating frame is a regular triangle rotating frame with rounded corners, the guide wheels are respectively fixed on the three corners of the rotating frame, the guide wheels are fixed on both sides of the track of the stacker, and the outside of the track There are two guide wheels and one guide wheel on the inner side. The turning guide device of the present invention for the upper beam of the stacker adopts the structure of three guide wheels. When this guide wheel structure runs on a straight track, the gap between the guide wheel and the track is 0mm. When the guide wheel runs on a curved track, The inner guide wheel is tangent to the track, and the gap between the outer guide wheel and the track is increased to 2mm, which significantly reduces the gap between the guide wheel and the track, and ensures the center of the track line of the upper beam guide wheel and the track Lines have a high degree of coincidence.

Description

technical field [0001] The invention relates to the field of stackers, in particular to a turning guide device for the upper beam of the stacker. Background technique [0002] The development of stacker technology has broken through some technical bottlenecks such as height and load. In some ultra-high stackers up to 30-40m, in order to make the stacker have a reasonable guide wheel clearance during the turning process, then in The straight track will adjust the clearance of the guide wheel. At present, the upper guide wheel and the lower guide wheel of the turning stacker on the market, generally each traveling wheel is equipped with 4 horizontal guide wheels, and two guide wheels are respectively set on both sides of the track. In order to prevent the guide wheels from getting stuck on the curved track, this This kind of guide wheel structure generally adjusts the gap in advance on the curved track. When the stacker walks on the straight track, the gap will increase a lot...

AI Technical Summary

Problems solved by technology

The comprehensive error of the upper beam guide wheel and the lower beam guide wheel in the traditional turning section reaches 15-20mm, so that the coincidence degree between the walking track line of the upper beam guide wheel and the center line of the track is not high enough, and the wear of the track and the guide wheel is uneven, resulting in The stacker produces high noise due to excessive shaking during high-speed movement
