Abstract

The invention provides a device for detecting multiple steel wire ropes and application thereof. The device comprises a bracket main body, wherein a plurality of detection bases are installed inside the bracket main body, each steel wire rope to be detected correspondingly penetrates through the middle of one detection base, a pair of lifting mechanisms is installed on the bracket main body, and can ascend and descend along the steel wire rope to be detected, so that the movement detection of the whole device on the multiple steel wire ropes can be realized. The device is used for detecting the steel wire ropes through a metal magnetic memory detection method. The adjustable device can guarantee the same lifting heights, the multiple steel wire ropes can be detected at a time simultaneously, the reference performance between the detection results is strong, the abrasion of a sensor can be avoided, and meanwhile, the detection precision can be guaranteed. A three-dimensional magnetic memory detection sensor is installed on the bracket, and the multiple steel wire ropes are detected according to the metal magnetic memory detection principle, so that the detection of stress concentration in the early stage and the prediction of the service lives of the steel wire ropes can be realized.

Description

technical field

[0001] The invention belongs to the field of construction engineering, and mainly relates to steel wire rope detection, in particular to a device and application for detecting multiple steel wire ropes. Background technique

[0002] Due to the advantages of high strength, good elasticity, strong impact resistance, light weight, and stable operation, steel wire ropes have been widely used in various fields such as elevators, passenger ropeways, cranes, construction hoists, and cable-stayed bridges. With the continuous improvement of building heights, elevators have become a necessary means of vertical transportation. Among them, the steel wire rope has the greatest impact on the safety of the elevator. During the operation of the elevator, in addition to bearing the design load, the steel wire rope will also be affected by other uncertain loads and special environments, resulting in broken wires, wear, corrosion and other damages, resulting in a decrease in i...

Examples

Embodiment 1

[0056] Comply with the above technical solutions, such as Figure 1 to Figure 9 As shown, this embodiment provides a device for detecting multiple steel wire ropes, including a bracket main body 1, a plurality of detection bases 2 are installed inside the bracket main body 1, and each steel wire rope 4 to be tested corresponds to a detection base 2 from the middle The wire walking chamber 2-2 passes through, and a pair of lifting mechanisms 3 are installed on the support main body 1, and the lifting mechanism 3 moves up and down along the steel wire rope 4 to be tested, so as to realize the motion detection of the whole device on multiple steel wire ropes.

[0057] The position of the detection base 2 in the bracket body 1 can be adjusted; the bracket body 1 includes a front support frame 1-1 and a rear support frame 1-2, and the front support frame 1-1 and the rear support frame 1- 2. Connect together through the connecting plate 1-3, so that a detection base movement cavity ...
