[0002] During the daily equipment maintenance and commissioning of substations, it is often necessary to work at heights. In order to ensure safety, the use of safety belts can prevent maintenance personnel from falling and causing personal injury. Due to the structure of the equipment and the requirements of relevant regulations, safety belts cannot be hung low and used high, and cannot be hung on unstable objects. Safety belts must be installed by installing a maintenance frame.

[0003] The existing publication number CN220142470U discloses a high-altitude operation anti-fall maintenance frame, which has a built-in anti-fall device and realizes secondary protection through the anti-fall device, thereby improving the safety effect.

[0004] Based on the above, the inventors found that the following problems exist: However, the safety of the anti-fall device is poor, and it relies solely on the friction between the metal pressure block, the movable arm and the channel steel for limiting. When the maintenance personnel slip, the safety belt will be pulled. The uncertain sliding direction causes the safety belt to be pulled, and the direction of the pulling force on the anti-fall device is also not fixed. When a large lateral force occurs, the metal pressure block, the movable arm and the channel steel will separate, causing the safety belt to fall with the maintenance personnel, which is extremely dangerous.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-altitude operation anti-fall maintenance frame is provided, in order to achieve a more practical purpose. Utility Model Content
