Description

Technical Field

[0001] This utility model belongs to the technical field of steel structure processing equipment, specifically relating to a special lifting equipment for hoisting steel structure components. Background Technology

[0002] In the current steel structure processing field, traditional handling methods are still widely used for loading and unloading small workpieces such as manhole rings and connecting plates during bending and drilling processes. Traditional handling methods are mainly divided into two categories: manual handling, where operators directly handle the picking, placing, and transferring of workpieces, with the advantage of requiring no additional equipment investment; and overhead crane handling, which uses large lifting equipment to transfer materials, possessing basic mechanization characteristics. From the perspective of overall industry development, most small and medium-sized steel structure processing enterprises still rely on traditional operating models, while only a few leading companies have begun to try introducing automated handling equipment. While specialized lifting tools are already in use within the existing technological system, they still need to be coordinated with overhead crane systems to complete vertical handling tasks, and a complete automated solution has not yet been formed. The existing technology system faces three core challenges: First, insufficient equipment adaptability. Traditional overhead crane systems have large rated loads that do not match the actual weight of small workpieces, leading to wasted equipment resources. Second, significant space constraints. Fixed overhead cranes rely on pre-set tracks, making flexible layout difficult in production environments with dispersed processes and limited space. Finally, limited energy supply. Traditional industrial equipment has high power requirements, making power supply a major challenge in temporary operations or field construction scenarios. Furthermore, existing solutions perform poorly in terms of human-machine collaboration, requiring operators to participate in auxiliary operations throughout the process, which hinders the improvement of overall transfer efficiency.

[0003] Therefore, providing a device that is easy to operate, has high transfer efficiency, and is suitable for various operating scenarios has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
