Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0022] In order to solve the problems of less control wire cores of ordinary elevator cables, larger twisting angles of vertical suspension of cables, and smaller U-shaped bending diameters, the present invention proposes a manufacturing method such as Figure 4 The method shown for ultra-multicore ultra-high-speed elevator cables.

[0023] refer to Figure 4 , a kind of manufacture method of ultra-multicore ultra-high-speed elevator cable, it comprises the steps:

[0024] The first step, refer to figure 1 First, 3, 4, 5, or 6 insulated cable cores 1 are twisted into corresponding 3-core primary composite cable cores 301, 4-core primary composite cable cores 302, 5-core primary composite cable cores 303, Or a 6-core primary composite cable co...

Abstract

The present invention discloses a method for manufacturing a super multi-core cable of a super high-speed elevator, the method comprises the following steps of: performing a first cabling twist on cores according to different numbers of cores; then performing a composite cabling twist on the insulation core set obtained by the first cabling twist, wherein direction of the composite cabling twist is opposite to the direction of the first cabling twist, and a back-twist twist is adopted; and simultaneously disposing a wire rope as a bearing component in the cable. The method in the present invention designed by the scheme solves the current situation of importing the high speed elevator cable and a problem of difficult maintenance of the elevator cable. The method of the present invention has the beneficial effects that number of the control cores is more, a torsion angle for vertical hang of the cable is small, and a U-shaped bending diameter of the cable is large.

Description

Technical field: [0001] The present invention relates to a kind of cable manufacturing method, more specifically, it relates to a kind of manufacturing method of ultra-multi-core ultra-high-speed elevator cable. Background technique: [0002] At present, the elevator cables produced in China are only suitable for elevator speeds of 4m / S and below, and the cables for elevators running faster than 4m / S (ultra-high speed) can only rely on imports. Ultra-high-speed elevator cables are often used in buildings with a height of more than 100M. At the same time, the building has high requirements for the running speed of the elevator. Due to the insufficient number of control wire cores, an elevator is used to assemble multiple ordinary elevator cables. Cables, and ordinary cables have technical defects, which cannot meet the requirements of high-speed operation of elevators. [0003] The requirements of the ultra-high-speed elevator for the elevator cable are: the number of contro...
