Description

Technical Field

[0001] The utility model relates to the technical field of simplified maintenance and repair auxiliary equipment, in particular to an elevator maintenance and repair operation auxiliary device. Background Art

[0002] An elevator is a vertical transportation device used to transport passengers or goods within a building. It is usually powered by an electric motor and runs between at least two vertical rigid rails or rails with an inclination angle of less than 15°. There are many types of elevators, including passenger elevators, freight elevators, medical elevators, utility elevators, sightseeing elevators, vehicle elevators, etc., which are designed according to different building needs and uses. There are also many classifications of elevator speeds, such as low-speed elevators, medium-speed elevators, high-speed elevators, and ultra-high-speed elevators, which help to distinguish elevators of different speeds. In addition, elevators are controlled in different ways, including elevators with drivers and elevators without drivers, as well as different control systems, such as handle switch manipulation, button control, signal control, collective selection control, and group control.

[0003] During the maintenance of the elevator, the staff needs to carry professional tools to work in the elevator shaft. After searching, the Chinese patent application number is: CN202110406485.4. It provides an elevator maintenance auxiliary device, including a mounting plate, and also includes: an oiling mechanism, the oiling mechanism is installed on the mounting plate, the oiling mechanism includes a coating component, an oil supply component, a stirring component and a power component for driving the coating component, the oil supply component and the stirring component to work, and the power component includes a clamping component and a driven component. The clamping component and the driven component cooperate to clamp the traction wire rope, so that the traction wire rope can drive the driven component to rotate when the traction wire rope moves. After the driven component drives the cleaning mechanism to reciprocate to clean the rust and oil on the traction wire rope, the driven component drives the stirring component to mix and stir the lubricating oil by driving the oil supply component to reciprocate to prevent the lubricating oil from stratifying due to long-term static; the driven component drives the oil supply component to evenly add the lubricating oil mixed by the stirring component to the coating component, and the coating component performs oil coating and maintenance on the traction wire rope.
