Embodiment Construction

[0041] This embodiment is a motion adsorption device for a wall-climbing robot, which includes four driving wheels 1, four timing belts 2, a plurality of suction cup assemblies 3 and two moving cams 4, which are divided into two groups and symmetrically installed on the frame. In this embodiment, a group of mechanisms is taken as an example to describe in detail.

[0042] In each group, there are two driving wheels 1, respectively a driving wheel and a driven wheel; each driving wheel is made up of a pair of web type synchronous pulleys 5 and 6 with the same shape and structure but opposite directions. In order to prevent the synchronous belt 2 from shifting on the tooth 7, one end of the tooth surface of the tooth 7 of the synchronous pulley is higher than the other end, forming a limit tooth step 13 of the synchronous belt 2 . There are weight-reducing holes 9 and weight-reducing grooves 12 on the web of the synchronous pulley; there are flanges 11 at the center of the corre...

Abstract

The invention relates to a motion adsorption unit of a wall-climbing robot; two groups of motion absorption mechanisms are symmetrically arranged on a frame, so that the two driving wheels (1) of each group of motion absorption mechanism are respectively arranged on the outer side of a shaft support (46) on one side of the frame; a moving cam (4) which is formed by the fitting of matched surfaces (36) is arranged on a moving cam support (47) on one side of the frame, so that the active wheel of the driving wheel (1) is on one end of the moving cam which is close to a stop section (38), and the circular arc of the stop section (38) and the active wheel are concentric; and the circular arcs on both ends of the outline of a cam piece and the active wheel and the passive wheel of the driving wheel (1) are concentric respectively. The motion adsorption unit of the wall-climbing robot uses the motion track of the moving cam (4) so that a vacuum sucker is easy and feasible in absorbing and leaving the wall surface, thereby not only realizing the flexible movement of the robot but also ensuring that all sucker components in the movement process can keep enough adsorbability, and is characterized by simple structure, convenient operation, easy control and high reliability.

Description

1. Technical field [0001] The invention belongs to the technical field of robots, in particular to a motion adsorption device for a wall-climbing robot. 2. Background technology [0002] There are many high-rise buildings in modern cities, and many wall maintenance operations are required. At present, this kind of work is still done by cleaning workers using high-altitude hanging baskets to carry out high-altitude operations. In this way, the working environment of workers is harsh and dangerous, and the work efficiency is also very low. Cleaning a building sometimes requires It takes days, so people are eager to use a machine to replace people to do this work. At present, many research institutions at home and abroad are competing to carry out work in this area, and the development of wall-climbing robots is also springing up. For the core of wall-climbing robots-movement and adsorption devices, various design schemes are emerging in an endless stream. [0003] A robot jo...
