Description

Technical Field

[0001] The present application relates to the field of property technology, and specifically to a property elevator maintenance guardrail. Background Art

[0002] Property refers to all types of houses that have been built and put into use, as well as their supporting equipment, facilities and venues. The main responsibilities of the property company include maintaining the public greenery and public order of the community, managing and maintaining public facilities and equipment, and other scopes agreed upon in the property service contract. When the property company repairs the elevator, it usually uses guardrails to warn passers-by.

[0003] For example, the Chinese utility model patent with the announcement number "CN 214145008 U" discloses an elevator maintenance guardrail for property management. The utility model moves the device to the elevator door through universal wheels. After adjusting the position, the electric telescopic rod is retracted so that the telescopic support rod contacts the ground to fix the device, and the telescopic clamping rod is extended so that the two ends of the telescopic clamping rod are attached to the two sides of the inner side of the elevator door, further preventing the device from moving, and the safety rope can be tied to the repairman.

[0004] In the above patent, the device can be supported when it is in use, but the length of the device is difficult to adjust. When the elevator is being repaired, the elevator door is sometimes open. If the length of the device is shorter than the elevator shaft, it is easy for the device to be pulled into the elevator shaft by the maintenance personnel through the safety rope, causing damage to the device and making it difficult to ensure the safety of the maintenance personnel.
