Anti-falling device for aerial working robot
The application belongs to the field of safety devices for aloft work, and particularly relates to a falling prevention device for an aloft work robot.
With the popularization of urban cities, high-rise buildings are gradually increased, and most high-rise buildings adopt glass curtain walls as a part of building construction. The outer surfaces of the glass curtain walls and the walls of the high-rise buildings are attached with dust, soil and the like along with the use time, or the outer walls need to be subjected to re-spraying operation so as to ensure the overall attractive appearance of the buildings.
The high-altitude outer wall operation robot is an auxiliary tool for replacing manual high-altitude operation, which is raised in recent years, and the personal safety threat possibly brought by manual operation is greatly reduced. However, the high-altitude outer wall operation robot may cause falling accidents due to self faults or insufficient climbing power, not only causes property loss, but also threatens the safety of people who walk down the building.

Example 2: an aerial working robot anti-falling device, wherein a water tank and/or a paint tank 13 is/are also arranged on the travelling trolley 1; the travelling trolley 1 is also provided with a pressure pump 7. The pulley 5 is arranged on the telescopic rod 4, and the bottom of the telescopic rod 4 is fixed on the travelling trolley 1. The sensor 10 is a radar range sensor or an infrared range sensor or a laser range sensor. The steel wire rope sling can adopt a water pipe with high tensile resistance. The travelling wheel 3 is driven by a motor or a gas engine, and the motor or the gas engine is positioned on the travelling trolley 1. The remaining unrecited structure is the same as that described in example 1.
In view of the above embodiments, the working process of the present application when in use is as follows:
the application is connected with the aerial working robot 12 through the elastic mechanism 11, the sensor 10 is positioned at the other end of the elastic mechanism 11, and in the initial state, the sensor 10 can sense the distance relative to the aerial working robot 12 and transmit the distance signal to the controller 2. The sensor 10 is one of a radar range sensor or an infrared range sensor or a laser range sensor that are commercially available.
After receiving the signal transmitted back by the sensor 10, the controller 2 feeds back the processed signal to the driving motor 6 in the winch, and adjusts the rotation speed of the driving motor 6. The rotation speed is adjusted as follows: (1) if the distance signal sensed by the sensor 10 and the distance signal in the initial state are kept within the range allowed by the set error, the driving motor 6 in the winch keeps the original rotating speed; (2) if the sensor 10 senses that the distance signal between the sensor 10 and the aerial working robot 12 is smaller than the signal in the initial state within the set error allowable range, the driving motor 6 in the winch increases the rotating speed, and the plate body where the sensor 10 is positioned is driven to ascend through the wire rope sling, so that the wire rope sling is ensured to be in the effective pulling force acting range for the aerial working robot 12; (3) if the sensor 10 senses that the distance signal between the sensor and the aerial working robot 12 suddenly increases and is larger than the signal in the initial state within the set error allowable range, the driving motor 6 in the winch reduces the rotating speed or stops working, and the state indicates that the aerial working robot may be in a fault state; (4) if the sensor 10 senses that the distance between the sensor 10 and the aerial working robot 12 is slowly increased within a set short time and the increased distance is larger than the set error allowable range, the controller 2 controls the driving motor 6 in the winch to put down the steel wire rope hoist at a constant speed, so that the sensor 10 and the aerial working robot 12 are in a relative initial state position.
A fence or a rail is often arranged at the top end of the building, so that the telescopic rod 4 is also arranged in the application, the top end of the telescopic rod 4 is provided with a pulley 5, and the wire rope sling bypasses the fence or the rail through the pulley 5 and the telescopic rod 4 to realize the connection of the aerial working robot 12.
