Technical Field

The invention relates to an installation method and an installation structure of an elevator traction rope, in particular to a hoisting method and a hoisting mechanism of an elevator synthetic fiber rope.

Background

In the field of elevator construction, the quality of the installation quality of the elevator steel wire rope greatly affects the service life of the elevator steel wire rope. From on-site investigation and analysis, almost 70% of the early failures of steel cords are due to improper installation operations; therefore, reasonable rope releasing plays a vital role in prolonging the service life of the steel wire rope. Especially on a high-rise elevator with a traction ratio of 2: 1, the steel wire rope is very long, so that the steel wire rope has practical significance on ensuring no damage in the whole rope releasing process.

In an elevator with a traction ratio of 2: 1, a common steel wire rope releasing method comprises the following steps: and (3) putting a single rope head of each steel wire rope down to the pit from the machine room, and after the rope head is wound around the counterweight diverting pulley, lifting the rope head to the machine room by using a winch. In the method, the steel wire rope can be seriously distorted due to uncontrollable suspension; the steel wire ropes are placed one by one, and then one steel wire rope is lifted, so that time and labor are wasted, and a large-stroke winch is needed. An improved payout method comprises the following steps: in the machine room, the counterweight-side rope head is manufactured firstly, and then each steel wire rope is downwards placed to the counterweight diversion sheave in a rope ring shape, so that certain distortion can be reduced, but the rope ring is not guided, so that once the lifting height is increased, the stroke of the rope ring is correspondingly increased, the steel wire rope still inevitably generates distortion, and the rope ring is easy to hook other well parts on a running line.

Patent CN201811432818.5 discloses a method for installing an elevator steel wire rope, which is fast and has a prolonged service life, and the steel wire rope reel is lifted to the top layer to release stress in a natural loosening manner, so as to avoid winding. Patent CN201210113580.6 discloses a method and a mechanism for releasing a rope of an elevator steel wire rope, which adopts a rope guide frame structure to install the steel wire rope, and the combination of the rope guide frame, a car, a counterweight and a traction rope wheel is complex to use and not beneficial to the installation of the counterweight frame in the later period.

With the development of elevator technology, in addition to a wire rope hoisting system which is commonly used in a hoisting elevator, in recent years, a steel belt hoisting system and a hoisting system such as a synthetic fiber rope represented by an aramid rope have been developed. Traction steel belts have been used on elevators gradually in recent years, and synthetic fiber ropes, as a highly new material, are being researched and tested by the elevator industry with its remarkable advantages.

However, the structure and method of synthetic fiber ropes during elevator installation has not been studied or disclosed. The existing scheme utilizes the self-weight characteristic of a steel wire rope, and aramid fiber ropes are light in self-weight, so that the aramid fiber ropes cannot adapt to a synthetic fiber rope structure with a large surface area.
