Problems solved by technology

[0004] In the case of replacing the main rope, it is necessary to connect the new rope to one end side of the old rope removed from the rope fixing part in the state where the car and the balance weight are fixed in the hoistway, and then, The old and new ropes are replaced by pulling the other end of the old rope. However, for an elevator that does not have a machine room at the top of the hoistway, this work must be performed in a limited space such as the hoistway and the elevator hall.

Embodiment Construction

[0027] Embodiments of the present invention will be described with reference to the drawings. figure 1 It is a schematic configuration diagram showing main parts of an elevator to which the main rope replacement device according to the embodiment of the present invention is applied.

[0028] figure 1 The illustrated machine-room-less elevator 1 is an elevator in which a car 4 and a counterweight 5 connected via main ropes 3 are moved up and down by the driving force of a hoist 6 in a hoistway 2 installed in a building. A top beam 7 is arranged on the top in the hoistway 2, and two top pulleys 8 are installed on the top beam 7. The hoist 6 is provided at a lower position in the hoistway 2, and has a hoist sheave 9 that rotates with a motor (not shown) as a drive source. The balance weight 5 is vertically guided along two guide rails (not shown), and a buffer 10 is provided at the inner bottom of the hoistway 2 to face the lower surface of the balance weight 5 .

Abstract

The invention provides elavator main rope replacement device and method, by that main rope replacement work can be easily completed regardless of the way travel of the elavator. The main rope replacement device (14) includes: a pedestal (17) disposed in a passenger car (15); a releasing roller (19) and a reeling roller (21) which are configured to the pedestal in a stacked multilayer structure andcan freely rotate around vertical direction; and a rope directing member (23) arranged on the pedestal. When a main rope needs to replace, a driving apparatus (12) is arranged on the top of the well(2), and relay rollers (13a, 13b) are installed on the passenger car; then, the unloaded used rope (3) is guided by the relay rollers and the driving apparatus, and the driving apparatus (12) is driven in the status that the used rope and a new rope (3A) are connected, thereby simultaneously performing a releasing action of releasing the new rope by the releasing roller (19) and a reeling action of reeling the used rope by the reeling roller (21).

Description

technical field [0001] The present invention relates to a main rope replacement device and a main rope replacement method for replacing a main rope of an elevator. Background technique [0002] In recent years, in order to save space in the installation place, elevators called machine room-less elevators, which do not have a machine room at the top of the hoistway, have become mainstream. This type of machine-room-less elevator is constructed in such a way that the two ends of the main rope are connected to the rope fixing part on the top of the hoistway, and the middle part of the main rope is wound around the weight pulley installed on the balance weight and the weight pulley installed on the lower part of the car. The lower pulley of the car and the hoisting sheave of the hoist arranged at the lower part of the hoistway drive the hoist to hoist the main rope, so that the car and the balance weight are hoisted in the hoistway in a bucket-like manner. [0003] In elevators...
