Elevator cable horizontal accelerated bending service life test equipment and test method

Abstract

The invention discloses elevator cable horizontal accelerated bending service life test equipment and a test method. The equipment comprises a horizontal high-speed reciprocating movement mechanism, afixed clamp mechanism and a conduction and voltage-resistant test device, wherein the horizontal high-speed reciprocating movement mechanism is arranged on a base; the fixed clamp mechanism is assembled on the base and can movably regulate the space; the conduction and voltage-resistant test device is connected with a plurality of conducting wire loops in an elevator cable. By using the test equipment and the test method provided by the invention, the elevator and cable service life test period can be obviously shortened. Compared with a vertical simulation operation service life test device,the equipment has the advantages that the period is shortened from 180 days to 75 days; the equipment investment, the fault rate and the test noise are exponentially reduced; the online conduction and voltage-resistant test device is favorable for improving the detection accuracy. The test equipment and test method provided by the invention have the advantages that great convenience is provided for the development and technology improvement of new products of elevator cables; powerful support is also provided for elevator manufacturers to fast evaluate the service life of the elevator cables;the equipment and the method can also be used for studying the elevator cable service life technology with the condition more strict than the practical operation conditions.

Description

technical field [0001] The invention relates to a cable testing device, in particular to a horizontal accelerated bending life test device and a test method of an elevator cable. Background technique [0002] Flat elevator cables are widely used in low-speed, medium-speed and high-speed (including ultra-high-speed) elevators. They are the mainstream types of elevator cables at present. They are responsible for elevator control and information signal transmission functions. They are important accessories for elevators. Their operating life is directly related to to elevator reliability and operating costs. The research on the life of elevator cables is an important topic in elevator technology and cable manufacturing industry. At present, there are the following four technologies for the life test of elevator cables. [0003] The European technology is to carry out the bending test on the cable. The diameter of the test wheel is 25 to 30 times the maximum thickness of the c...
