Abstract

The invention relates to an overspeed brake, a braking device, a braking system and a window cleaning machine. The overspeed brake comprises a brake disc, a gear, a roll ball, an ejector pin, a friction plate and a gear shaft, wherein the brake disc comprises a gear installation space and is provided with a mounting hole which is through with the gear installation space; the gear is installed in the gear installation space of the brake disc in a pivoted mode; the roll ball is located at the position of a tooth groove of the gear and movably arranged in the brake disc; the ejector pin is movably installed in the mounting hole, and the roll ball drives the ejector pin to move in the direction far away from the gear installation space in the mounting hole; the friction plate is installed on the side of the gear; and the gear performs braking on the gear shaft through the friction plate. The overspeed brake has the advantages of being simple in structure and good in safety and is particularly suitable for the window cleaning machine.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an overspeed brake, a brake device, a brake system and a window cleaning machine. Background technique [0002] With the continuous advancement of urban modernization, in order to meet the needs of urban construction, various high-rise buildings have sprung up, and the cleaning and maintenance of the exterior walls of these high-rise buildings has gradually become a problem. In order to be able to To safely clean and maintain the walls, window cleaning machines emerged as the times require, and have become indispensable equipment for the cleaning of these high-rise buildings. In order to meet the needs of different shapes of buildings, it is necessary to produce various types of window cleaning machines, and the tilting telescopic arm type window cleaning machine is one of them. The telescopic arm type window cleaning machine is usually driven by a motor gear rack and a chain. In the pitc...
