Embodiment Construction

[0035] Hereinafter, an embodiment of the end cap rotation preventing device for a main rope according to the present invention will be described based on the drawings.

[0036] figure 1 It is a diagram showing a schematic configuration of an elevator to which the rope end loop preventing device for main ropes according to the present invention is applied. figure 2 yes means figure 1 Front view of the rope end provided with the elevator shown.

[0037] figure 1 Indicates an elevator with a general 2:1 roping ratio. as it should figure 1 As shown, the elevator includes a car 1 , a counterweight 2 , and main ropes 3 for suspending the car 1 and the counterweight 2 . One end 3a and the other end 3b of the main rope 3 are held by, for example, a hoisting machine load beam 4 provided in an equipment room disposed above the lifting path. The main rope 3 is wound around a car-side pulley 5 provided in the car 1 , a traction pulley 6 and a guide pulley 7 provided in the equipmen...

Abstract

The present invention provides a rope socket rolling stopper of a main rope. The rope socket rolling stopper of the present invention is applied to an elevator having a first rope socket (9A), a second rope socket (9B), and a third rope socket (9C) which are respectively installed to main ropes (3A, 3B, 3C), and comprises: a first plate (11) which is connected with a pin (15) inserted into a through hole (9Aa) of the first rope socket in a rotatable way; a second plate (12) which is connected with the first plate (11) in a relative rotation way and is connected with a pin (16) inserted into a through hole (9Ba) of the second rope socket in a rotatable way; a first plate (13) which is connected with the pin (16) in a rotatable way; and a second plate (14) which is connected with the first plate (13) in a relative rotation way and is connected with a pin (17) inserted into a through hole (9Ca) of the third rope socket in a rotatable way.

Description

technical field [0001] The present invention relates to a rope end cover of a main rope that restricts mutual rotation of the rope end sleeves respectively attached to the plurality of main ropes during tension adjustment work of a plurality of main ropes suspending a car and a counterweight of an elevator Stop device. Background technique [0002] Generally, an elevator includes a car, a counterweight, a plurality of main ropes for suspending the car and the counterweight, and a plurality of end caps attached to both ends of the main rope. The above-mentioned tensions of the respective main ropes vary year by year, and this variation leads to problems such as accelerated wear and deterioration of the main ropes. Therefore, it is necessary to periodically adjust the tension of each main rope to be constant. During the tension adjustment work of such main ropes, when each main rope rotates about its axis, the tension of the rotating main rope changes. Therefore, it is nece...
