Hoister lifting method of elevator for super high-rise building

Abstract

Disclosed is a hoister lifting method of an elevator for a super high-rise building. An elevator hoister as a heavy goods can be hoisted to the top of a building, which is located at a super high position, by utilizing a universal lift winch. A lift winch (13) is disposed at the uppermost elevator hall (4), a deceleration rope (19) pulled out and winded by the lift winch (13) is winded between a fixed pulley (16) and a movable pulley (17) to form a deceleration winded rope, overhanging ropes (20, 21) capable of being segmented are used to connect the movable pulley (17) and an elevator hoister (23) and drives the lift winch (13) so that the elevator hoister (23) is hoisted to middle layers (2, 3), the elevator hoister (23) is temporarily placed on support mechanism parts (24) and (12) of the middle layers (2) and (3), the overhanging rope (20) at the lowermost part is removed and the overhanging rope (21) at the upper part is connected with the elevator hoister (23) when the elevator hoister (23) is at a temporarily placed state, the lift winch (13) is driven again, and then the elevator hoister (23) is hoisted to a mechanical room (9).

Description

technical field [0001] The present invention relates to a method of hoisting a heavy object such as an elevator hoist to an extremely high position using an inexpensive, general-purpose crane with a small lifting capacity in a super high-rise building. Background technique [0002] In recent years, along with the super-high-rise buildings, the super-high-rise and large-scale elevators are increasingly progressing. In direct proportion, the hoist used to drive the elevator also shows a tendency to be super-large and super-weight. Especially outside of Japan, the number of construction plans for buildings with 100 floors or more is enormous, and this tendency is considerably conspicuous. [0003] The elevator hoist installed in this type of super high-rise building must be arranged in the uppermost machine room. Therefore, how to hoist the hoist as a super-heavy cargo to the uppermost machine room has become a big issue. [0004] Of course, if a construction tower crane with ...

AI Technical Summary

Problems solved by technology

[0014] Thereby, when using above-mentioned general-purpose winch, can carry out hoisting to 10~20 layers of middle and high-rise elevator winches with the hoisting method of above-mentioned patent document 1, but for 50-100 floors or higher super high-rise elevator Hoist, its winch capacity (lift and traction) is insufficient and cannot be applied

[0015] Furthermore, for the lifting method of the 2-to-1 roping method disclosed in the above-mentioned patent document 2, there is also the problem that the general-purpose winch cannot match the lifting height (lift)
