Multi-fulcrum crane

Abstract

The invention discloses a multi-fulcrum crane, and relates to the field of cranes, the multi-fulcrum crane comprises a main beam, the two ends of the main beam are connected with a steel structure of a workshop through first hanging pieces, the main beam is formed by connecting a plurality of sub main beams, the sub main beams are connected through connecting pieces, and the connecting pieces are connected with the steel structure of the workshop through second hanging pieces; the length of the first hanging piece is larger than that of the second hanging piece, and the span of the main beam corresponds to the width of a workshop. The hoisting structure is movably arranged on the main beam; the control unit is in control connection with the hoisting structure; the main beam and the workshop steel structure are connected through the multiple hanging pieces, the first hanging pieces with the long length are adopted at the two ends, the second hanging pieces with the short length are adopted in the middle, the complete deformation of the main beam is reduced, meanwhile, the requirement for large-span loads is met, the crane can improve the object transferring efficiency of a workshop in a limited workshop space, the daily output of a conveying line is increased, and the production cost is reduced. And meanwhile, the working efficiency is improved, and obvious economic benefits are obtained.

Description

technical field [0001] The invention belongs to the field of cranes, and more specifically relates to a multi-support crane. Background technique [0002] In manufacturing, KBK rails, tool rails and aluminum alloy rails are generally used, but according to the layout design of automobile manufacturing workshops and the requirements of process routes, large-span cranes are required for automobile production lines, assembly lines, logistics cross-regional sorting lines, etc. However, since none of the above-mentioned tracks can meet the load requirements of large-span cranes, it will reduce the transfer efficiency of workshop items and affect work efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a multi-support crane for the deficiencies in the prior art. The crane connects the main girder with the steel structure of the workshop through multiple hanging parts. The second hoist with a shorter length is used to reduce the comp...

[0003] The purpose of the present invention is to provide a multi-support crane for the deficiencies in the prior art. The crane connects the main girder with the steel structure of the workshop through multiple hanging parts. The second hoist with a shorter length is used to reduce the complete deformation of the main girder and at the same time meet the demand for large-span loads. The crane can improve the transfer efficiency of the workshop in the limited workshop space, increase the daily output of the conveyor line, and play a role The role of high turnover and high capacity efficiency, while improving work efficiency and achieving obvious economic benefits
