Embodiment Construction

[0020] Embodiments of the elevator equipment according to the present invention will be described below with reference to the drawings.

[0021] Such as figure 1 As shown, the elevator equipment of this embodiment has: an elevator car 2 ascending and descending in the hoistway 1; pulleys 2a1-2a4 supported by the elevator car 2; The cable ends 3 are arranged on the top of the hoistway, extend downward and are respectively wound on the pulleys 2a1-2a4, then extend upward again to suspend the elevator car 2, and cross above the elevator car 2; , which drives the sling 4a wound on the other end side of the sheave 5a; and the anti-sway device 6, which is provided at the crossing position of the slings 4a, 4b.

[0022] Such as image 3 As shown, the anti-sway device 6 is configured to have cylindrical passing bodies 6a, 6b, and the cylindrical passing bodies 6a, 6b are arranged so that the crossed slings 4a, 4b can pass through the interior respectively, and It is possible to kee...

Abstract

The invention, using a simpler structure, prevents deflection in elevator ropes. An elevator having a rope (4) that, after being wound from above around an elevator car (2) to be lifted in an elevator shaft, is installed again above the car, wherein the rope from above (4a) and the rope installed above again (4b) are disposed to intersect above the elevator car (2). Cylindrical pass-through bodies (6a, 6b), provided so that the ropes (4) are inserted and each rope (4) maintains a mutual distance, and a device, in which the cylindrical pass-through bodies (6a, 6b) are mutually rotatable and that follows the intersection angle of the ropes (4) that varies along with the lifting of an elevator car (2), are provided in the location where the ropes (4) intersect.

Description

technical field [0001] The invention relates to an elevator accessory, in particular to an anti-sway device for an elevator sling, which can prevent the swaying of the elevator sling. Background technique [0002] Generally, when an earthquake or strong wind occurs, the hoistway of the elevator and the slings for suspending the elevator car arranged in the hoistway shake as the building shakes. In addition, in the case of outdoor elevators, the longer the hoistway, the greater the possibility of the sling being shaken by the wind. When the sling shakes, the sling may come into contact with various equipment arranged in the hoistway and cause the elevator to fail to operate. Therefore, it is necessary to install a device to prevent the elevator rope from shaking. [0003] In the prior art, as such a device for preventing the sway of the elevator rope, the device disclosed in Patent Document 1 can be cited. The sling sway preventing body is arranged on the upper part of the...
