Problems solved by technology

[0004] In the above-mentioned adsorption methods, most of the adsorption technology devices are single suction cups, and they only have good adaptability to specific wall surfaces, the safety factor is not high, and they cannot make appropriate responses according to different wall surfaces to adapt to the wall surface.
Most of the single suction cups in the multi-sucker adsorption method do not have a parallel mechanism, lack the synergy of each suction cup, and provide power for each suction cup, and the energy consumption is high
At the same time, the multi-sucker adsorption method lacks the perception of the wall environment, and cannot automatically respond to the different environments, forming a local area of ​​each small sucker, which generates adsorption when the conditions are good, and does not produce suction when the conditions are not good. adsorption

Abstract

The invention discloses an adsorbing unit with automatic switching behavior and an adsorbing device. The adsorbing device comprises more than three adsorbing units, an air cavity, an air suction element, a motor and a bottom plate bracket, wherein all the adsorbing units are fixedly arranged on the bottom plate bracket; conduits of all the adsorbing units are communicated in parallel through the air cavity; and the air suction element is connected to an outlet of the air cavity and is driven through the motor to suck air from the air cavity, so that negative pressure is formed in the adsorbing device. According to the adsorbing unit and the adsorbing device, whether the situation of a contacted wall face is good or bad can be sensed under a complex wall face working environment, a response is made instinctively, reliable adsorption of the entire device is realized, and complex working environments can be flexibly and reliably adapted.

Description

technical field [0001] The invention belongs to the self-adaptive adsorption technology, in particular to an adsorption unit and an adsorption device which can form a stable adsorption on the rough and uneven wall surface with automatic switching behavior. Background technique [0002] Adsorption robot, as an automated device that can replace humans in dangerous and difficult work, has a very large range of applications in bridge inspections, cooling towers, and dam inspections. In the above applications, the adsorption robot should be able to absorb horizontally and vertically on the surface of the building, and maintain a certain load capacity. To make the adsorption robot work stably in a complex working environment, a good adsorption device is essential. Adsorption devices with poor performance will seriously affect the adsorption force of the adsorption robot, causing the adsorption robot to fall off due to insufficient adsorption force. Therefore, designing a reliabl...
