Embodiment Construction

[0030] attached figure 1 It is a schematic diagram of an elevator wire rope maintenance method in the prior art. In the figure, 1 is a fixed pulley, 2 is a connecting card, 3 is a movable pulley, 4 is a wire rope, and 5 is a fixed end. As can be seen from the figure, in the prior art, the elevator wire rope maintenance method includes the following steps:

[0031] (1) Start the elevator so that the car reaches the top floor, hang the hoist on the top of the car, and prepare to lift the car;

[0032] (2) Place the special tool at the lower end of the elevator counterweight, and stop the elevator after the elevator car is lifted and the counterweight falls to the pre-placed wooden pile position; the special tool is a section of 200×200×2000 stake;

[0033] (3) According to the elongation of the steel wire rope, use a hoist to lift the car to a certain position. The position is such that the wire rope can exceed its elongation by 200 mm. The hoist is a commonly used electric li...

Abstract

The invention provides an elevator steel wire rope overhauling device and an overhauling method of the elevator steel wire rope overhauling device, which aim at overcoming the problems of more working hours, a great amount of labour consumption, low safety factor and accordingly-caused industrial injuries or fatal accidents in the elevator steel wire rope overhauling device and the overhaul method of the elevator steel wire rope overhauling device in the prior art. According to the elevator steel wire rope overhauling device and the overhauling method of the elevator steel wire rope overhauling device in the invention, all overhauling operations can be realized by only one person within two hours, the safety factor is high, multiple active safety protection measures are provided, and the anthropic safety risk is reduced.

Description

technical field [0001] The invention relates to an elevator maintenance device and its maintenance method, in particular to an elevator wire rope maintenance device and its maintenance method. Background technique [0002] As a kind of special equipment, the installation and maintenance process of the elevator belongs to the high-altitude operation, and the requirements for safety are very high. Among them, the traction elevator drives the car through the elevator main wire rope, fixed pulley and movable pulley. Usually, the elevator steel wire rope is a group of multiple wire ropes. In the actual use process, the degree of elongation due to different toughness is also different. In this way, the discreteness of the performance of the steel wire ropes and the tension test error during the initial installation and debugging, After working for a period of time, the elongation of the steel wire rope is different, which intensifies the wear of the steel wire rope and the fixed ...
