Device and method for testing static tension of safety rope for aloft work

Abstract

The invention provides a device for testing the static tension of a safety rope for aloft work. The device comprises a support body which is a square frame structure. One end in the support body is connected with a telescopic device, and another end of the telescopic device is fixedly connected with a first holder fixer. The first holder fixer is fixedly connected with the first holder through a sensor, and another end in the support body is fixedly connected with a second holder fixer. The second holder fixer is fixedly connected with a second holder through a connecting rod, the positions ofthe first holder and the second holder correspond to each other, and an upper end and a lower end of the first holder fixer are in sliding connection with a holder sliding guide rail arranged on an inner side of the support body. The detection process is simple, the automation degree is high, the safety characteristic of a load holding time of the safety rope under the action of certain static tension in the aloft work is simulated for testing, a computer control mode is adopted, and the automation degree is high.

Description

technical field [0001] The invention relates to a static tension testing device and a testing method for a safety rope for high-altitude operations, and belongs to the field of performance parameter testing of safety ropes for high-altitude operations. Background technique [0002] For the usual fiber rope products, people pay attention to the mechanical performance indicators such as breaking strength and elongation at break, but often ignore the working load and static tension of the fiber rope. The rope is usually stretched during use, especially under the condition of a certain force, and it will often work under a certain force for a long time. At this time, it is called the static tension. 3min static tension ≥ 15KN, type B rope requires at least 3min static tension ≥ 12KN. More obviously, especially in high-altitude operations, safety ropes are related to the life safety of operators. Safety protection technology and equipment for working at heights originated in Eu...

AI Technical Summary

Problems solved by technology

[0003] At present, domestically and internationally, the concept of static tension of safety ropes for high-altitude operations has been proposed, but the static tension test instrument system for basic performance has not been established, there is no test method for static tension of safety ropes, and there is no corresponding testing equipment. However, due to the insufficient refinement of domestic safety rope processing, there is not enough awareness of the static tension performance of safety ropes
