Mooring rope for elevator

Abstract

The invention provides a mooring rope. Maintenance is convenient, the service life can be prolonged, the intensity can be raised, the diameter of the mooring rope is shortened, and therefore the mooring rope is suitable for miniaturization of an elevator system. The mooring rope comprises a core part (1), a plurality of side wires (12) arranged along the periphery of the core part (1), and auxiliary wires (13) arranged at the valley sections between adjacent side wires (12) at the outer side of the side wires (12). The side wires (12) are formed by a plurality of wires through twisting. The wires are formed by normal round wires. The auxiliary wires (13) are formed by a plurality of wires through twisting. The outer wires (32) are formed by special-shaped wires. The wires except the outer wires (32) are formed by normal round wires. The circumcircle (A) of each side wire (12) and the circumcircle (B) of each auxiliary wire (13) are internally tangent with the same circle approximately.

Description

technical field [0001] The present invention relates to an improved construction of cables for running ropes used in elevators. Background technique [0002] Ropes can be broadly classified into standing ropes and moving ropes according to their usage. The stationary cable is at rest with a load applied to it, while the active cable passes over a sheave or is wound on a drum with a load applied to it. [0003] A typical movable cable is an elevator sling, and the cable 101 used as the elevator sling is, for example, as Figure 5 As shown, an elevator car 104 and a counterweight 105 are connected by a sheave 102 linked with a driving motor to change the direction of the cable 101 and a pulley 103 for changing the direction of the cable 101 . The elevator car 104 ascends and descends by the rotation of the sheave 102 and the traction force of the rope 101 . At this time, since a bending stress is applied to the cable 101 in a state where a load is applied to the cable 101 , ...

AI Technical Summary

Problems solved by technology

[0016] In this case, maintenance is required by the electromagnetic flaw detection method. Although this electromagnetic flaw detection method can detect whether a wire breakage has occurred, it cannot determine the exact location where the wire breakage occurred.

Also, it is impossible to disassemble the moving cable even if it is known that the part invisible to the naked eye has broken

Therefore, in the prior art, it takes a lot of labor, time and cost to maintain and inspect the cables

[0017] The cable disclosed by the above-mentioned Patent Document 2 is not only complicated in structure, labor-intensive and time-consuming in manufacture, and high in cost, but also has the problem that it is difficult to reduce the diameter.
