Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing, and in particular to a large-scale shaft sleeve part conveying and turning device. Background Art

[0002] Many large sleeve parts in mining equipment are long in size and heavy in weight. In order to meet the needs of different workstations during the assembly process, high requirements are placed on their positioning, clamping and rotating devices.

[0003] In the process of assembling the above-mentioned large-scale shaft sleeve parts into mining equipment, it is usually necessary to use a single-beam crane to lift the large-scale shaft sleeve parts. In the process of lifting the large-scale shaft sleeve parts using the single-beam crane, it is first necessary to tie the slings to the large-scale shaft sleeve parts according to the length and center of gravity of the large-scale shaft sleeve parts, and then use the single-beam crane to slightly lift the large-scale shaft sleeve parts. Through preliminary lifting, it is observed whether the lifting posture of the large-scale shaft sleeve parts meets the installation requirements. If the lifting posture does not meet the installation requirements, it is necessary to readjust the position of the binding to the large-scale shaft sleeve parts and adjust the lengths of the two slings. The above-mentioned fixing method depends entirely on the operating experience of the on-site operator, and often requires multiple adjustments to barely meet the installation requirements. Due to the long size and heavy weight of the large-scale shaft sleeve parts, there is a certain degree of difficulty in aligning them after lifting them with the single-beam crane, resulting in a long alignment process. In addition, during the lifting process, the large-scale shaft sleeve parts sometimes slip from the slings. This sliding phenomenon will cause the large-scale shaft sleeve parts to rotate, posing a major safety hazard. At the same time, the installation time is long and the assembly efficiency is low.
