An automatic cleaning machine for stair handrails

Abstract

The invention discloses an automatic cleaning machine for a stair armrest. The automatic cleaning machine comprises a walking arc-shaped supporting plate, three first telescopic electric cylinder bottom plates, three first telescopic electric cylinders, three first connecting discs, nine first shock absorbers and three second connecting discs, wherein the three first telescopic electric cylinder bottom plates are symmetrically fixed at the inner side of the walking arc-shaped supporting plate respectively, and the bottoms of the three first telescopic electric cylinders are fixed on the threefirst telescopic electric cylinder bottom plates respectively. The automatic cleaning machine for the stair armrest has the advantages that firstly the movement of the automatic cleaning machine on the armrest is achieved through three walking wheel mechanisms fixed on the walking arc-shaped supporting plate, the three first telescopic electric cylinders can be adjusted according to different diameters, the nine first shock absorbers can adapt to the situation that the automatic cleaning machine can be in contact with the armrest at the corner of the armreast all the time, and three small sucking discs are arranged to increase the walking adhesive force; three flexible connections are adopted between the walking arc-shaped supporting plate and a first arc-shaped cleaning supporting plate,so that steering motion of the automatic cleaning machine can be achieved better.

Description

technical field [0001] The invention relates to the technical field of sanitation and cleaning, in particular to an automatic cleaning machine for stair handrails. Background technique [0002] Stairs are an indispensable way of public traffic, and the handrails of the stairwells are quite unhygienic. People always hold the handrails when they go up and down the stairs. Bacteria, leading to the infection of the disease, the staff is also quite strenuous when cleaning up. Due to the complex structure of modern railings, it is cumbersome to use the traditional wiping method, which is a thankless job, and for taller high-rise buildings Cleaning up the dust on the stair railings also quite tests the physical strength of the sanitation workers, therefore, there is an urgent need for a device that can automatically clean the stairwell railings and handrails. Contents of the invention [0003] In view of the above problems, the present invention provides an automatic cleaning ma...
