Stair rail cleaning robot

Abstract

The invention relates to a stair armrest robot cleaner which is formed by a climbing structure and a cleaning system; the climbing structure is formed by a reciprocated pushing structure and a clamping rotation structure, the reciprocated pushing structure is formed by a driving motor, a deviation cam, a connecting rod, a front sliding block, a back sliding block, a guide rail polished shaft, a front pushing block, a back pushing block and a pushing block, the clamping rotation structure comprises a front clamping hand and a back clamping hand, each clamping hand is formed by a convex rotary connecting piece, a clamping claw, an ejection rod, a first compression spring and a jump ring, the front clamping hand and the back clamping hand are installed on the front sliding block and the back sliding block in a rotatable mode respectively, and the ejection rods in the clamping hands are abutted against the front pushing block and the back pushing block under the effect of the first compression springs. The cleaning system of the stair armrest robot cleaner is formed by a trigger type cleanout fluid jetting device and a cleaning brush. The stair armrest robot cleaner for achieving single power source driving through the design that a cam centre mechanism is ingeniously combined with a connecting rod mechanism is provided.

Description

technical field [0001] The invention belongs to the field of automatic robots and relates to a robot for automatic cleaning of stair handrails. Background technique [0002] With the development of human society, the population continues to increase. According to statistics, as of October 31, 2011, the world's population has exceeded 7 billion. One of the problems with the increase in population is that land per capita has decreased. In order to solve this problem, the general practice of various countries is to build buildings as high as possible to improve the utilization rate of land. Especially in my country, high-rise buildings have become a typical feature of modern cities in our country. Buildings are built high, which brings great inconvenience to people's travel, so elevators came into being. However, elevators cannot completely replace traditional stairs. One is that for people with low floors, taking the stairs can exercise your body without spending a long t...
