Technical Field

[0002] Transmission tower aerial work robots are auxiliary tools that have emerged in recent years to replace manual aerial work, greatly reducing the personal safety threats that may be caused by manual work. However, transmission tower aerial work robots may cause falling accidents due to their own failures or insufficient climbing power, which not only causes property losses, but also poses a threat to the safety of people passing under the building.

[0003] Existing anti-fall devices, such as the anti-fall device for aerial work robots disclosed in the utility model patent with application number 201621416188.9, have a main structure including a wire rope sling, a walking trolley, a winch, a controller, a walking wheel, a sensor, and an elastic mechanism, wherein the winch, the controller, and the walking wheel are all located on the walking trolley, the winch includes a drive motor, a reducer, and a drum, the drive motor is connected to the drum through the reducer, the drum is connected to the sensor through a pulley and a wire rope sling, an elastic mechanism is provided under the sensor, and the controller is connected to the drive motor and the sensor respectively; when in use, when the sensor senses that the distance signal between it and the aerial work robot suddenly increases and is greater than the signal in the initial state within the set error allowable range, the drive motor in the winch reduces the speed or stops working, and this state indicates that the aerial work robot may be in a fault state.

[0004] However, the working environment of aerial work robots on transmission towers is relatively complex, and existing anti-fall devices are relatively simple and difficult to apply to complex outdoor environments.
