Technical Field

[0001] The utility model relates to the field of elevator maintenance, and in particular to an elevator maintenance anti-falling support device. Background Art

[0002] Elevators are complex mechatronic systems. Just as cars require regular maintenance to ensure normal use and safety, elevators also require regular maintenance by professionals to promptly detect and eliminate potential safety hazards and avoid elevators running with problems.

[0003] During the maintenance process of the elevator, if a malfunction occurs, it is easy to cause the elevator car to fall suddenly, posing a serious threat to the life safety of the elevator maintenance personnel. The existing elevator maintenance support device is generally large in size, which makes it inconvenient to carry during maintenance work. In addition, when the existing elevator maintenance support device is in use, its drive unit cannot be disassembled, so that multiple drive units need to be set in the device for driving. Moreover, the device cannot operate when any motor is damaged, and needs to be disassembled and repaired, which is time-consuming and labor-intensive.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content
