[0002] With the development of high-end equipment manufacturing industry, especially the popularization of large-scale CNC equipment and automation equipment, equipment maintenance has become an indispensable part. In actual equipment failure maintenance, the damaged control or electrical hardware module in the electrical cabinet must be replaced. At this time, manpower is often required to lift the module to a specific position and maintain a certain height, and then move and adjust the posture to the installation hole or slot to complete the installation. However, the interference of narrow space and various installed large components is difficult to avoid. When the weight of the module increases, it is located at a higher disassembly position or it is necessary to connect cables of limited size at a specific non-installation position height, it will cause installation difficulties, time-consuming and labor-intensive, and it is difficult for one person to complete or even multiple people cannot collaborate to implement. Therefore, it is urgent to design a power-assisted support and delivery combination device, which has the characteristics of simple on-site assembly and fixation, and can adapt to the complex space in the electrical cabinet. It can assist in lifting and pushing when implementing module installation or disassembly operations, so as to achieve the purpose of convenient and labor-saving module disassembly and assembly, especially for the installation of heavier modules that need to be fine-tuned to the corresponding installation position.
