Description

Technical Field

[0001] The utility model relates to the technical field of elevator maintenance, in particular to a safety maintenance device for elevator maintenance. Background Art

[0002] With the continuous development of modern building technology, elevators, as an important tool for vertical transportation, play an increasingly important role in people's lives and work. However, after long-term operation and frequent use, elevators will inevitably have various faults and damages, which require repair and maintenance. Elevator maintenance is a high-risk operation involving electrical, mechanical and other aspects. Once an accident occurs, it may threaten the life safety of maintenance personnel and surrounding personnel. In the process of elevator maintenance, in order to prevent people from getting close to or accidentally touching the elevator and causing injuries, fences will be set up at the elevator entrance to block the elevator entrance. At present, the common fences are movable guardrails or folding fabric fences. When in use, these fences are placed at the elevator entrance to prevent people from getting close to the elevator entrance. Although they can play a certain isolation role at the elevator entrance, this kind of fence is usually placed directly on the ground, with poor stability. When people are not paying attention or children approach and touch it, the fence is easy to fall over, causing the elevator entrance to lose the barrier of the fence, with poor protection performance and certain safety hazards.
