Problems solved by technology

[0005] However, when the number of supports is large, it takes a lot of time and labor to draw the thread between the supports.
[0006] In addition, in order to prevent the hooking of ropes, etc., it has also been considered to pull the wire that connects the inner wall of the hoistway and the bracket. When the shaft is shifted, the silk thread may become loose or broken

Abstract

The present invention provides a device for preventing hooking cable of an elevator, the device may easily arranged in hoistway and may reliably prevent the cable from hooking components in the hoistway. The device (9) for preventing hooking cable is arranged in the hoistway to prevent a speed limiter cable being hooked by components in the hoistway. The device for preventing hooking cable comprises a penal shaped limiter member (21) for limiting swing of the limiter cable; a slide body (22) arranged on the limiter member 921) in manner of sliding, the slide body sliding respect to the limiter member (21), and the limiter body (22) may contact and move away respect to inner wall of the hoistway; and a force apply spring (23) applying force towards direction of contacting with the inner wall of the hoistway. The slide body (22) slides respect to the limiter member (210 in case that the inner wall of the hoistway shifts respect to the limiter member (21) because of such as earthquake, and in case that the slide body (22) contacts with the inner wall of the hoistway.

Description

technical field [0001] The present invention relates to an anti-cable hooking device of an elevator, which can suppress the swing of the cable so as to prevent the cable from being hooked by parts in the hoistway. There are cables in the hoistway, such as moving wiring connecting the control panel and the car. Background technique [0002] In a general elevator, a plurality of brackets are arranged at intervals in the vertical direction in the hoistway in order to support the rails. Therefore, when, for example, an earthquake occurs, the ropes or moving wires in the hoistway often swing and are caught by the brackets. [0003] Therefore, in order to prevent ropes and the like from being caught by the brackets due to vibrations such as earthquakes, an elevator in which wires are stretched between the brackets has been proposed. Thereby, even if a rope etc. swings, it can suppress that a rope etc. enters between each bracket (for example, refer patent document 1). [0004] ...
