Ultra-multicore ultra-high-speed flat elevator cable testing apparatus

Abstract

The invention discloses an ultra-multicore ultra-high-speed flat elevator cable testing apparatus which comprises a cable testing apparatus, connecting posts, a wheel disc, a rocker bar, a drive rod,a receiving hopper, a display screen, a box door, a control panel and anti-slide bottom studs, wherein totally four connecting posts are arranged at the upper ends of the anti-slide bottom studs. Thecable testing apparatus disclosed by the invention is composed of a starting device, an extrusion device, a tensile testing apparatus, a limiting device, an insulation testing apparatus, a feeding mechanism and an alarm device. The apparatus is capable of testing the tensile strength of cables during straightening and bending, so that the tensile strength data of the cables in different states areexact, and the condition that a cable breakage accident easily occurs due to a large data error during use can be avoided. Meanwhile, the apparatus is capable of detecting whether the insulating layer of the cable contains defects, and the phenomenon that electric leakage and electric shock easily occur in the cable operating process can be avoided.

Description

technical field [0001] The invention relates to an ultra-multi-core ultra-high-speed flat elevator cable test device, which belongs to the field of elevator cables. Background technique [0002] Super-high-rise super-high-speed elevators with a lifting height of more than 150 meters and an elevator running speed of more than six meters per second usually use large cars. Therefore, U-shaped bending of the accompanying ultra-multi-core flat elevator cables is required The diameter must reach 650 mm or more, the running height is high, and the speed is fast. The manufacture and test of this flat elevator cable are completely different from ordinary flat elevator cables. It is a single straight-running tensile strength test. Since the cable frequently bends and moves up and down with the elevator car during laying, the tensile strength of the cable when it is bent is quite different from the tensile strength when it is straight. The tensile strength test data of the cable is no...

Problems solved by technology

[0003] Aiming at the deficiencies existing in the prior art, the object of the present invention is to provide a super multi-core ultra-high-speed flat elevator cable test device to solve the problem that the elevator cable test device adopts a single straight-running tensile strength test for the cable. During the laying process, the elevator car frequently bends and moves up and down. However, the tensile strength of the cable when it is bent is quite different from the tensile strength data when it is straight, which leads to the inaccurate detection data of the tensile strength of the cable, resulting in Accidents of cable breakage are prone to occur during use, and at the same time, it is difficult for the device to detect the insulation degree of the cable, which leads to problems of leakage and electric shock during operation
