Embodiment Construction

[0028] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0029] figure 1 It is a figure which shows the schematic structure of the elevator which used the jig fall prevention apparatus which concerns on this embodiment. figure 1 Among them, the structure of the elevator EL is as follows: the car 2, the hoist 3 and the counterweight 4 are connected inside the lifting path 1 through the main rope 5, and the car 2 is lifted and lowered by the rotation of the hoist 3. On the car 2 , the speed governor 6 that detects the dangerous lifting speed is connected to the car 2 via the speed governor rope 7 . For example, the speed governor 6 is sometimes arranged at the top of the lifting path 1, and the maintenance work of the speed governor 6 must be performed above the car 8 .

[0030] figure 2 It is a diagram showing the speed controller, jig and beam arranged on the top of the lifting path. The speed governor 6 is attached to a...

Abstract

The invention provides a jig tool fall prevention device capable of preventing a jig tool to be used from falling under a lift car or into a hoistway even when an apparatus such as a speed governor rope is arranged below an object when working on the lift car. A jig tool fall prevention device includes: a sheet-like fall prevention part (18) for receiving when a jig tool (11) falls; a gap (20) formed at the fall prevention part (18) so as to sandwich a speed governor rope (7); a fastener (19) for closing the gap (20); a handheld part (22) which can be wound around the speed governor rope (7), and which is mounted on the fall prevention part in such a manner that one end is not attachable / detachable and the other end is attachable / detachable, respectively; and a suction part (17) for attachably / detachably mounting the fall prevention part between a beam for mounting a speed governor and a handrail (13) on a lift car (8). Also, it includes an outer side fastener (23) for closing an outer edge of the fall prevention part in an openable manner and making it into a bag shape.

Description

technical field [0001] The present invention relates to a jig drop prevention device, and more specifically, to a jig drop prevention device used in elevator maintenance work. Background technique [0002] As such a device, for example, the technology described in Japanese Patent Laid-Open No. 2002-284469 (Patent Document 1) is known. The technology is characterized by an elevator car device, comprising: a handrail on one side, the lower part of which is pivotally connected to the edge of one side of the upper part of the car, and is usually laid flat on the top surface of the car, Set upright when necessary; the other handrail, the lower part of the other side handrail is pivotally connected to the edge of the other side of the upper part of the car that is opposite to the above-mentioned one side, and is usually laid flat on the above-mentioned top surface. If necessary, it is erected; the detector is arranged on one of the above-mentioned one side armrest and the other s...
