Problems solved by technology

[0007] However, there is a problem that the structure is too complicated in the anti-snag device disclosed in the above-mentioned patent document for absorbing changes in the distance and angle between the first end and the second end due to earthquakes, etc.
[0008] In addition, due to the structure in which the first end is connected and fixed to the wall of the hoistway, a large-scale construction is required
In addition, since the fixed side of the first end needs to have the strength to withstand the large force acting on the anti-hook device during an earthquake, etc., it is impossible to use a light-weight wall or made of glass in the hoistway wall. When securing sufficient strength, it is necessary to add reinforcing materials, which makes installation difficult

Abstract

The invention provides a strip-shaped member anti-hooking device for an elevator, wherein the device is capable of preventing the vibration of an earthquake by adopting a simple structure and actually preventing a strip-shaped member from being hooked. The strip-shaped member anti-hooking device (14) for the elevator comprises a protection member (14a) and an elastomer (14b). The protection member (14a) can be freely moved along the end portion of a device bracket (7) through a hinge (14c). Meanwhile, the protection member (14a) extends along the wall (1) of a lifting channel. The elastomer (14b) is used for pressing the end portion of the protection member (14a) onto the wall (1) of the lifting channel.

Description

technical field [0001] The invention relates to an anti-hooking device for long strip-shaped components of an elevator. Background technique [0002] In the hoistway of the elevator, a plurality of equipment supports are installed on the guide rails, and equipment such as position detection switches, induction plates, and control cables are installed on the equipment supports. On the other hand, the elevator is provided with elongated components such as the main sling for suspending the elevator car and the counterweight, the cables arranged on the elevator car, and the governor rope arranged on the governor. In the event of an earthquake, etc., the elongated member may be caught on the equipment stand due to shaking, causing damage to the equipment and the elongated member. [0003] Therefore, as a background technology for preventing elongated members from being hooked, Japanese Patent Laid-Open No. 2011-26021 of Patent Document 1 discloses a method of preventing wires fr...
