Variable form wall cleaning robot, its cleaning method and its obstacle surmounting method

Abstract

The invention provides a variable-form wall surface cleaning robot, a cleaning method, and an obstacle-surmounting method. The invention includes a tractor and a cleaning robot. The deformed frame of the cleaning robot includes a frame, at least one back-push fan is installed on the back of the frame, an upper pressure nozzle assembly and a lower pressure nozzle assembly are arranged on the front of the frame, and a water tank and a water tank are arranged on the tractor. The upper pressure nozzle assembly and the lower pressure nozzle assembly are connected through the water supply pipe. The deformation frame on the front of the frame includes four outriggers. The first end of the outriggers is hinged with the frame. / The two lower outriggers are fixedly connected by fixed rods, the upper outrigger and the lower outrigger are hingedly connected by a moving rod, a positioning rod is fixed between the two moving rods, and the outrigger and the frame are still movable A telescopic pusher is connected, an upper wiper and a lower wiper are fixedly installed on the two moving rods, at least one cleaning mechanism is arranged between the upper wiper and the lower wiper, and the cleaning mechanism is fixed on the positioning rod.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a high-rise cleaning tool, in particular to a variable-form wall cleaning robot, a cleaning method, and an obstacle-surmounting method. Background technique [0002] The traditional cleaning technology of high-rise buildings mostly adopts manual suspension or hanging basket cleaning. Both cleaning methods rely on manual labor, which is inefficient and dangerous. In high-altitude operations, the cross wind speed is fast and the wind pressure is high. The two cleaning methods rely on the natural suspension of the rope. Under the influence of the cross wind, it is easy to swing, which not only affects the personal safety of the workers, but also easily damages the walls and Clean equipment. [0003] Existing wall cleaning robot platforms are too heavy. The hoist used to lift the machine needs to be fixed on the top of the building, and the hoist needs to be moved and fixed after e...

AI Technical Summary

Problems solved by technology

The hoist used to lift the machine needs to be fixed on the top of the building. After each cleaning task, the hoist needs to be moved and fixed again. The erection process is time-consuming and laborious, and it is very inconvenient to use

[0004] Existing wall cleaning robots are mostly used for cleaning glass curtain walls. The vacuum suction cups equipped with the walking mechanism have high requirements on the smoothness of the wall surface, and can only walk on the glass surface, so the usage scenarios are relatively single.

The moving speed of the traveling mechanism is slow and the working efficiency is low

[0005] The cleaning mechanism equipped with the existing wall cleaning robot can only complete the wall cleaning work in the direction from top to bottom. There is an empty return when the robot descends to the bottom of the cleaning surface and then lifts to the top of the cleaning surface, which affects the operation. efficiency

[0006] Existing wall cleaning robots are equipped with a complex structure and heavy weight, and cannot climb over obstacles with a height of about 30-50 cm such as window sills, water supply and drainage pipes, or open glass curtain walls. higher flatness requirements
