Cam-type negative pressure adsorption wall-climbing robot

Abstract

The invention discloses a cam-type negative pressure adhering wall-climbing robot. By means of an inverse cam mechanism and a passive vacuum absorption mechanism, the negative pressure absorption function of a sucker is achieved and the limitation brought by a vacuum source device is eliminated. The adsorbing and detaching process of the vacuum sucker is easy through a mechanical structure. The structure is simple and the absorption force of the sucker is strong due to the negative pressure. By means of an adsorbing steering mechanism, the limitation of the minimum turning radius of a tracked robot is avoided and the pivot steering function is achieved. Adsorbing moving mechanisms are positioned on the two sides of a main baseboard of the robot; a steering power mechanism is fixed on the main baseboard; steering wheel components are connected with the steering power mechanism through flexible threaded rods; and by adjusting the position of a cam track groove, a steering auxiliary mechanism mounted on the main baseboard enables the adsorbing steering mechanism to work. The linear moving portion is connected with the linear steering portion through a screw transmission manner, the moving process of the robot is achieved through reasonable step arrangements, so that the cam-type negative pressure adsorption wall-climbing robot is easy to control and applicable to wide working range.

Description

technical field [0001] The invention relates to the field of wall-climbing robots, in particular to a wall-climbing robot with cam-type negative pressure adsorption. Background technique [0002] With the increasing number of high-rise buildings in cities, the demand for maintenance of high-rise building walls is also increasing. At present, this kind of work is mainly done by cleaning workers on high-altitude hanging baskets. This kind of extreme operation is not only dangerous, but also has low work efficiency. Therefore, there is an urgent need for an efficient and fast robot to replace manual operations to complete this work. Many research institutions at home and abroad are competing to carry out research in this area; according to the way the robot is adsorbed on the working wall, wall-climbing robots are generally divided into three categories: vacuum adsorption type, magnetic force adsorption type, and thrust type. At present, vacuum adsorption is the most widely us...
