Oil sludge removing device and elevator with same

Abstract

The invention discloses an oil sludge removing device used for removing oil sludge in pulley grooves. The oil sludge removing device comprises fixing arms and scraping blades; each fixing arm comprises a flat portion used for being attached to and fixed to a frame of a keeping pulley; and each scraping blade comprises one or more scraping shovels of which the shapes and the positions adapt to those of the pulley grooves and extending portions which vertically extend on the planes of the scraping shovels, the scraping blades are connected with the fixing arms, and the fixing arms and the scraping blades are configured in the mode that when the fixing arms are attached to and fixed to the frame of the keeping pulley, one or more scraping shovel surfaces of the scraping blades face and abut against the surfaces of the pulley grooves. The invention further discloses an elevator comprising one or more oil sludge removing devices. The oil sludge removing device is installed on the elevator,the elevator runs in a detection state of the elevator, oil sludge accumulated in rope grooves of elevator pulleys can be automatically removed, heavy work of maintenance personnel is avoided, the working efficiency is improved, and the oil sludge removing device which is simple in structure, flexible to install and high in oil sludge removing efficiency is achieved.

Description

technical field [0001] The present invention relates to sludge cleaning devices, and more particularly, to sludge cleaning devices for pulleys. Background technique [0002] Pulleys are usually used to guide ropes. The ropes usually contain lubricants, corresponding to lifting devices such as elevators with a travel height greater than or equal to 75m. After one or two years of operation, the rope lubricant will come out of the rope core and reach the rope surface, so it will mix with dust , when the temperature drops sharply below 5 degrees Celsius, the mixture of lubricant and dust will form oil scale or sludge, which will harden and accumulate on the groove of the pulley. Accumulated oil or sludge interferes with the guidance of the rope by the pulley, creating a risk of the rope jumping out of the groove of the pulley. [0003] When the temperature drops sharply, a large amount of grease quickly accumulates on the pulley grooves, sometimes even in a day, so that the rop...

Problems solved by technology

Accumulated oil or sludge interferes with the guidance of the rope by the pulley, leading to the risk of the rope jumping out of the groove of the pulley

[0003] When the temperature drops sharply, a large amount of grease quickly accumulates on the pulley grooves, sometimes even in a day, so that the guidance of the rope by the pulleys of the hoisting device suddenly becomes poor, because the grease on the pulley grooves affects the pulleys. diameter

[0004] When grease appears on the pulley grooves, it will be difficult and time-consuming for maintenance personnel to remove the grease

Worse, when grease builds up on the deflectors at the bottom of the sling, it is difficult for staff to clean
