Problems solved by technology

At this time, since it is impossible to distinguish whether the electrical conduction is caused by the contact between the strand bundles to be inspected or the contact in the sling holding device, it is difficult to conduct a high-level inspection of the damage of the sling. The problem of accuracy detection

Abstract

The present invention provides a suspension rope type elevator, capable of preventing the suspension rope from flattening and performing high-precision conduction inspection to the suspension rope. A holding device for fixing the suspension rope (1) on a building is composed of a holding wedge-like component (2) for holding the suspension rope (1), a coiling wedge-like component (3) for coiling the suspension rope (1) to hold the suspension rope (1), a clamping fixture (4) and a sleeve (5) for accepting said components, such that it is possible to prevent the suspension rope (1) coated with resin from flattening, prevent compound yarn bundles constituting the suspension rope from contacting mutually, and improve the conduction detection precision of the suspension rope.

Description

technical field [0001] The present invention relates to a sling elevator, in particular to a device capable of solving new problems arising from the improvement of slings and realizing highly reliable detection of the slings. Background technique [0002] The cable elevator that is suspended by wire ropes is the mainstream elevator among all kinds of elevators. In the cable elevator, the sling is wound on the sheave installed on the hoist. An elevator car is suspended, and a counterweight for balancing with the elevator car is suspended on the opposite side. The wire rope is fixed on the wall of the elevator car and the counterweight or the hoistway through the wedge-shaped sleeve. Wherein, the wedge-shaped sleeve is made by filling a steel sleeve with babbitt alloy or arranging a steel wedge-shaped member in the steel sleeve. [0003] However, in recent years, in order to reduce the size of the hoisting machine and the diameter of the sheave, etc., resin-coated straps, sl...
