Problems solved by technology

The Chinese patent application number 01138618.5 discloses a method for realizing a crawler-type multi-suction cup wall-climbing robot. The robot is large in size and complex in structure; CN97121896 discloses a "wall-climbing robot". Driven by the power, the fan generates a thrust pointing to the wall, so that the robot sticks to the wall; the efficiency of this wall climbing method is low, so the application is greatly limited
[0005] In short, the existing wall-climbing robots are large in size, complex in structure, high in energy consumption, low in wall-climbing efficiency, and difficult to realize self-service posture conversion function

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] combine figure 1 and figure 2 , a kind of negative pressure adsorption type wall-climbing robot of the present invention with self-service attitude conversion function adopts modular design method, and it comprises four parts, are respectively: negative pressure generating device 41; Driving device 43; Supporting and sealing device 40 And control device 42. Wherein the negative pressure generating device 41, the control device 42, and the battery are arranged on the rear portion of the robot support base plate 24, so that the horizontal distance b from the center of mass T01 to the rear wheel rotation center is about 1 / 3 of the front and rear wheel span L, so that the robot It has the function of attitude conversion from the ground walking state to the wall climbing state by itself. The range of the ratio b / L between the distance b between the cent...

Abstract

The invention discloses a negative pressure adsorption wall-climbing robot, which comprises a negative pressure generating device, a control device, a supporting and sealing device and a moving device, wherein the range of the ratio of the distance between a human mass center of the robot and a rear wheel to the span between a front walking wheel and a rear walking wheel is less than or equal to 1/3. Two character-shaped maze type clearance seals are adopted between an impeller and a pump body in the negative pressure generating device of the robot. A sealing strip on an edge of a base plate of the robot is fixedly connected to the base plate, and the interior of the sealing strip is filled with sponge. The sealing strip is fixed on the base plate or adhered to the base plate through a mounting press batten, has a seamless integral structure and is made from rainproof silks, and the base plate of the robot is provided with a plurality of ventilation holes. The negative pressure adsorption wall-climbing robot has a simple structure, is small-sized and effective, and has a function of self-realization of switching a ground walking state to a wall-climbing state.

Description

technical field [0001] The invention belongs to the field of robot technology and automation, in particular to a negative pressure adsorption wall-climbing robot capable of realizing wall surface conversion by itself. Background technique [0002] With the development of science and technology, anti-terrorist investigation, high-rise building inspection, wall cleaning and other fields often need robots that can realize the function of climbing walls. This robot can carry a variety of sensors to complete the task. [0003] Most of the existing wall-climbing robots are large in size and use more magnetic adsorption. This kind of robot can only crawl on the magnetically conductive surface, which is relatively heavy and consumes more energy. The efficiency of wall-climbing is low, and it is generally difficult to do. to go cableless. [0004] The Chinese patent application No. 200610151073.6 discloses a small wall-climbing robot based on the principle of negative pressure adso...
