Description
Technical Field
[0001] The utility model relates to the technical field of elevator maintenance, in particular to an elevator maintenance anti-fall rod. Background Art
[0002] Elevators are handling equipment used to transport people and goods in high-rise buildings in modern society. The elevators themselves often rely on the traction system to drive the elevators to move up and down horizontally, which can quickly complete the transfer of people and goods between different floors. Now the distance between high-rise buildings in cities is increasing, and the number of supporting elevators is also increasing. People use elevators more and more frequently. After long-term use, elevators will inevitably have certain problems, which need to be repaired in time to ensure the normal use of elevators. When repairing the elevator shaft, in order to ensure the safety of workers, it is necessary to prepare anti-fall rods for tying safety ropes to protect construction workers and reduce safety hazards;
[0003] When the current anti-fall rod is in use, the anti-fall rod is placed on the outside of the elevator door wall and is clamped on the elevator door frame by the pulling force provided by the workers to achieve the anti-fall function. However, in actual use, the length of the anti-fall rod is usually fixed. Due to the different sizes of the elevator door walls, when the elevator door wall is wider, the anti-fall rod cannot match the elevator door wall, and the length of the anti-fall rod cannot be adjusted according to the width of the elevator door wall. There are certain usage restrictions and poor practicality. At the same time, the anti-fall rod cannot be fixed again during use, and the anti-fall rod may be displaced, which makes it impossible to effectively play the role of anti-falling, and there are certain safety hazards. Therefore, we provide an elevator maintenance anti-fall rod. Utility Model Content
