A wall-climbing robot

Abstract

The invention discloses a wall-climbing robot. Currently, wall-climbing robots are urgently needed for replacing manual operation. The wall-climbing robot comprises an equipment carrier platform, foottype obstacle crossing mechanisms, tracked crawling mechanisms and air distribution systems. Each air distribution system comprises hinge type flat-bottom skirted suckers, an air distribution plate and sucker connectors, wherein the air distribution plate synchronously rotates along with the corresponding tracked crawling mechanism; the n sucker connectors are fixed to tracks; the sucker connectors are spherically hinged to tail ends of the hinge type flat-bottom skirted suckers; the sucker connectors are hollow internally, one end of each sucker connector is internally communicated with thecorresponding hinge type flat-bottom skirted sucker, and the other end of each sucker connector is communicated with an air distribution hole of the air distribution plate through an air guide pipe. Alternate air suction of every two hinge type flat-bottom skirted suckers in the same group is changed through a two-position four-way reversing valve, and an air suction port of each two-position four-way reversing valve is communicate with a vacuum generator through an air delivery pipe. By adoption of the foot type obstacle crossing mechanisms, great obstacle crossing performance is achieved; owing to a difference between pressure intensity in each sucker cavity and pressure intensity of the external barometric pressure, the wall-climbing robot is attached on a concrete wall surface.

Description

technical field

[0001] The invention belongs to the technical field of robots, and in particular relates to a wall-climbing robot. Background technique

[0002] Concrete construction is the most common type of construction in the world today. Due to the influence of the external environment and human factors, many concrete buildings have potential safety hazards, such as cracks, spalling, surface honeycombing and other disease characteristics, which have adverse effects on project quality, use effect and safety. In the treatment of apparent diseases, sometimes it is necessary to add concrete slurry to the diseased part for reinforcement and treatment.

[0003] Currently, there are two detection and treatment methods for concrete walls. The first method is that the worker descends slowly by means of the sling, and then performs the operation. The second method is to put up the scaffolding for climbing first, and the workers rely on the scaffolding to carry out their operat...
