Wall climbing robot airflow adsorption technology and walk operation platform

Abstract

The invention discloses an adsorption technology using air flow negative pressure and a wall climbing robot operation platform which realizes adsorption and walking on a wall surface by using the adsorption technology. In the platform, high-speed air flow is generated by using gaps between an adsorption disk and the wall surface by a fan, so negative pressure is generated due to flow rate difference of two sides of the adsorption disk and the adsorption and walking on the wall surface is finished under the friction action of walling wheels and the wall surface. The adsorption between the robot and the wall surface in a gap way is realized by fully using air flow negative pressure, so that the adsorption efficiency is high; self weight is light, and relatively large redundant load is achieved so as to meet the wide climbing operation requirements; the wall climbing robot operation platform is suitable for wall surfaces made of various materials, such as glass, metal, ceramic tiles, coating, cement and the like; the wall climbing robot operation platform can be applied to an arc wall surface with a small curved surface; and the wall climbing robot operation platform has a simple structure, and low manufacturing cost and is favorable for industrial production and popularization.

Background technique: [0002] Wall-climbing robots can be used in curtain wall cleaning, wall coating operations, high-rise building fire protection, public security investigation and other fields. The wall-climbing robot should have the basic functions of wall adsorption and walking, and must also provide effective operating loads in addition to overcoming its own gravity.

AI Technical Summary

Problems solved by technology

The negative pressure adsorption method is divided into vacuum suction cup type and dynamic negative pressure adsorption type. The vacuum suction cup type is only suitable for smooth surfaces such as glass and metal and has a complicated moving mechanism. The method is to generate negative pressure in the cavity through fan suction and adsorb on the wall surface. Although this method is not limited by the wall material, since the adsorption force is mainly realized by the negative pressure in the cavity, the gap with the adsorption surface is small and the adsorption Limited force, difficult to provide payload

In addition, the fan thrust attachment or fan thrust auxiliary attachment also has the problems of high fan power requirements and poor energy efficiency.

[0004] CN101412415A has announced a kind of " wall-climbing robot " of anti-thrust and negative pressure compound adsorption method, and its existing problems are as follows: first, propeller thrust is limited as a main adhesion force, and efficiency is low and energy consumption is big; The realization of airflow negative pressure will inevitably produce turbulent flow, and the adhesion force generated by the difference in flow velocity cannot be effectively used

[0005] To sum up, none of the negative pressure wall-climbing robot adsorption technologies and work platforms announced so far can realize the adsorption and walking of different material walls and provide payload, so it is difficult to apply to a wide range of wall-climbing operations.
