Positioning and lifting system for large structural member

Abstract

The invention relates to the technical field of assembly, in particular to a positioning and lifting system for a large structural member. The positioning and lifting system for the large structural member comprises lifting devices and a limiting device, wherein the lifting devices comprise lifting plate assemblies, spiral elevators, guide mechanisms, falling prevention mechanisms and bases, the spiral elevators and the guide mechanisms are both arranged on the bases, the lifting plate assemblies are driven to lift through the spiral elevators, the guide mechanisms are provided with guide columns, the lower sides of the lifting plate assemblies and the upper ends of the guide columns are fixedly connected, the lower ends of the guide columns extend into the bases, the falling prevention mechanisms are arranged in the bases, the falling prevention mechanisms correspond to the guide mechanisms one by one, the falling prevention mechanisms comprise limiting sliding blocks and air cylinders, the lower parts of the guide columns are provided with notches, when the lifting plate assemblies are lifted in place, the limiting sliding blocks are driven by the air cylinders to move and be clamped in the notches on the corresponding guide columns, and lifting detection assemblies are arranged on the base. An in-place detection assembly is provided on either lifting device. The positioningand lifting system for the large structural member ensures the safety and improves the automation level and the working efficiency of a production line.

Description

technical field [0001] The invention relates to the technical field of assembly, in particular to a positioning and lifting system for large structural parts. Background technique [0002] At present, the assembly of large structural parts is completed on a fixed platform or tooling. The transportation of structural parts is generally completed by hoisting, but this method not only wastes time and manpower, but also the working process is relatively dangerous, and it is impossible Meet the requirements of intelligent manufacturing. For example, in the assembly process of AGV (Automatic Guided Transport Vehicle) and other devices carrying workpieces, the existing bench or tooling cannot realize the in-place detection of AGV and other transportation carriers, and cannot automatically implement follow-up actions. These At present, human manipulation is required, which poses great difficulties to the beat control and quality control of the entire production line. In addition, du...

[0002] At present, the assembly of large structural parts is completed on a fixed platform or tooling. The transportation of structural parts is generally completed by hoisting, but this method not only wastes time and manpower, but also the working process is relatively dangerous, and it is impossible Meet the requirements of intelligent manufacturing. For example, in the assembly process of AGV (Automatic Guided Transport Vehicle) and other devices carrying workpieces, the existing bench or tooling cannot realize the in-place detection of AGV and other transportation carriers, and cannot automatically implement follow-up actions. These At present, human manipulation is required, which poses great difficulties to the beat control and quality control of the entire production line. In addition, due to the large volume and weight of large structural parts, accidents are prone to occur in actual production, causing the lifting device to fail and cause danger.
