[0002] Electromechanical safety fence is a facility used to protect the safety of electromechanical equipment and working areas. It is usually made of solid materials, such as steel, and has a certain height and strength. Its main function is to prevent people from accidentally entering dangerous areas and to prevent electromechanical equipment from being disturbed and damaged by the outside world. It can also serve as a warning and isolation. It is widely used in industrial production, mechanical processing and other fields, providing an important guarantee for safe production.

[0003] When performing maintenance on electromechanical equipment, it is necessary to open the guardrail for operation. The guardrail is usually fixed with bolts. This method has a low cost, but the bolts need to be removed to open the guardrail, which is inconvenient to operate. Adding an automatic lifting device to the guardrail facilitates the operation of workers, but the commonly used automatic lifting device requires structural steel columns to be set up around the equipment for support. After the guardrail is raised to the top, the structural steel columns occupy a large space, which hinders the maintenance of the equipment. Therefore, we need to consider how to reduce the problem of excessive space occupied by the lifting device. Utility Model Content
