Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] as attached Figure 1-9 As mentioned above, the present invention provides a step cleaning device, which includes two stair climbing mechanisms 1 and a cleaning mechanism 2, and the two stair climbing mechanisms 1 are arranged symmetrically at intervals; the cleaning mechanism 2 is vertically arranged between the two stair climbing mechanisms 1 , for cleaning steps or ground.

[0038] The stair climbing mechanism 1 includes two walking wheel sets 11 and a telescopic adjustment mechanism 12 arranged front and back. The distance between the front and back of the wheel set 11 is to meet the cleaning requirements of steps of different heights or widths. Each walking wheel group 11 comprises two stair-climbing telescopic rods 111, wheel support frames 112, wheels 113, wheel travel motors 114, wheel steering motors 115 and transver...

Abstract

The invention discloses a stair cleaning device. The stair cleaning device comprises two stair climbing mechanism symmetrically arranged at intervals, wherein cleaning mechanisms are vertically arranged between the two stair climbing mechanisms, and each stair climbing mechanism comprises two movably connected travel wheel groups respectively arranged in front and rear parts; each travel wheel group comprises two stair climbing expansion links that are vertically arranged in parallel, and a transverse connection rod is horizontally arranged between the two stair climbing expansion links; a wheel support is arranged at the lower end of each stair climbing expansion link; wheels are rotationally connected to the wheel supports; and a wheel travel motor is fixedly installed on each wheel support, and the output end of the wheel travel motor is fixedly connected to the corresponding wheel. According to the stair cleaning device, the two stair climbing mechanisms are arranged in front and rear parts, and the stair climbing expansion links are arranged in the stair climbing mechanisms, so that when the cleaning device travels to the lower side of a stair, the stair climbing expansion links are extended and retracted to drive the wheels to lift up along a stair surface, and thus automatic lifting of the cleaning devices is achieved; and the cleaning mechanisms are arranged between thestair climbing mechanism, so that cleaning of the floor and corridor stairs is achieved.

Description

technical field [0001] The invention belongs to the technical field of cleaning devices, in particular to a step cleaning device. Background technique [0002] With the development of society and the improvement of science and technology, people's requirements for quality of life are getting higher and higher, and the number of high-rise buildings in our country is increasing day by day. Although most buildings choose to install elevators, in order to prevent power outages or other emergencies Corridors must exist; the current cleaning of corridors is manual cleaning, but the cleaning of high-rise building corridors is not only a heavy workload, but also inefficient, which is greatly difficult to meet the current fast-paced modern life; existing indoor cleaning machines It is only suitable for flat cleaning, and cannot adapt to the corridor environment of complex spaces. Contents of the invention [0003] Aiming at the technical problems in the prior art, the present inve...
