Curtain wall glass cleaning robot

Abstract

The invention discloses a curtain wall glass cleaning robot. Four mechanical legs are arranged below a robot body, soft sucking discs are arranged below the four mechanical legs, a cleaning brush anda collecting mechanism are arranged in the robot body, a winding tube is arranged on the upper portion of the robot body, linear executors are arranged on the shafts of the mechanical legs, tripods which sleeve the shafts of the mechanical legs are arranged on the tops of the soft sucking discs, connecting beads are connected with other ends of the tripods, and bases fitting with the soft suckingdiscs are arranged on the side faces of the soft sucking discs; corrugated pipes which expand when heated are arranged in inner cavities of the soft sucking discs, heating bars are installed on the tops of the corrugated pipes, the corrugated pipes contain mercury, two ends of the corrugated pipes are provided with vertical grooves and positive and negative electrodes which are communicated with the mercury respectively, and the on and off of the linear executors and the heating bars are controlled by the positive and negative electrodes through a control system. According to the robot, the soft sucking discs have higher vacuum degree through the characteristics of expansion caused by heat and contraction caused by cold of the corrugated pipes and the mercury, and therefore the robot can fix on the curtain wall glass.

Description

technical field [0001] The invention relates to the field of curtain wall cleaning technical equipment, in particular to a curtain wall glass cleaning robot. Background technique [0002] The curtain wall cleaning robot is a mobile robot for the purpose of cleaning high-rise buildings. It can replace human beings in high-altitude professional work, thereby reducing human labor and avoiding the danger of people falling from high-altitude operations. Among the existing curtain wall cleaning robots, such as the application number: 201610477982.2, titled: A high-altitude glass curtain wall cleaning robot. The robot announced in this invention moves through the bionic mechanism of the legs. When it needs to be fixed on the curtain wall, the armature on the chamber is attracted by the electromagnet, and the The larger the space, the greater the vacuum degree, and form a certain pressure difference with the outside of the chamber to fix the robot. However, the change of the space i...

[0002] The curtain wall cleaning robot is a mobile robot for the purpose of cleaning high-rise buildings. It can replace human beings in high-altitude professional work, thereby reducing human labor and avoiding the danger of people falling from high-altitude operations. Among the existing curtain wall cleaning robots, such as the application number: 201610477982.2, titled: A high-altitude glass curtain wall cleaning robot. The robot announced in this invention moves through the bionic mechanism of the legs. When it needs to be fixed on the curtain wall, the armature on the chamber is attracted by the electromagnet, and the The larger the space, the greater the vacuum degree, and form a certain pressure difference with the outside of the chamber to fix the robot. However, the change of the space in the elastic chamber is actually affected by the space between the suction cup claw and the elastic chamber. Pursue the space in the elastic chamber to become larger, the place where the elastic chamber connects with the suction cup claw will be stressed, and the edge of the suction cup claw will be folded, so that the vacuum degree will be destroyed, and the purpose of not fixing the robot on the curtain wall will not be achieved, so During the use of this invention, it will fall due to insufficient suction after being fixed in one place for a long time. If there are no protective measures, the robot will cause the danger of ground personnel being smashed
