Problems solved by technology

When this "secondary protection" method is used, the bending radius of the cable at the metal mesh is not less than 300mm. Due to the limitation of the installation size, when the middle part of the cable cannot be kept in the plumb state, the cable will be damaged during the operation of the car. There is a relatively large shaking
At the same time, there is no corresponding "secondary protection" measure for flat cables

Abstract

The invention discloses a suspension device of an elevator trailing cable or compensating cable utilizing steel wire ropes as bearing parts. The device is composed of threaded rope ends (1), nuts (2), locking pieces (3) and supports (4). The end portions of every bearing steel rope of a cable (13) are connected with the rope ends (1) in a pressing mode, the nuts (2) and the locking pieces (3) fix the rope ends onto the supports (4), and the nuts (2) are adjusted to enable the lengths of the bearing portions of the steel wires with the rope ends to be the same. The supports (4) at both ends are fixedly onto the bottom of a car (0) and the bottom of a counterweight (00) or the wall of a shaft (000). When secondary protection is needed, a suspension support (7), a clamping piece (8) and corresponding connection bolts are additionally arranged at the bottom of the car, and a section of freely overhung cable is arranged between the suspension support (7) and one of the supports (4). Further, the suspension (7) is provided with safety contacts (12), and when the cable snaps the clamping piece (8) or slides aside, the safety contacts can be cut off to enable an elevator to stop or to be unstartable.

Description

technical field [0001] The invention relates to a suspension device for elevator accompanying cables or compensating cables, which is suitable for elevators and uses steel wire ropes as load-bearing parts. Background technique [0002] At present, when using wedges, cylindrical winding, clamping, etc. to suspend elevator accompanying cables or compensation cables with steel wire ropes as load-bearing parts, very long cables are required for suspension. For example, when the diameter of the steel wire rope is 3mm, its length is about 300~ 500mm, or even longer, so hanging with wedges, cylindrical winding, clamping, etc. increases the length of the cable. [0003] In the production process of the suspension, the load-bearing steel wire rope of the above length should be stripped from the cable; in order to ensure that the stress of each steel wire rope in the same cable is close to the same, it is necessary to make the length of the load-bearing part of the steel wire rope clo...
