Abstract

The invention relates to the technical field of strength testing, and provides a jig for testing the dynamic impact strength of a chain and a rope. The jig comprises a machine frame, a fixing position, a bearing assembly and a lifting mechanism, wherein the fixing position is arranged on the top of the machine frame and is connected with one end of the chain to be tested and one end of the rope to be tested, the bearing assembly is located below the fixing position and is connected with the other end of the chain to be tested and the other end of the rope to be tested, the weight of the bearing assembly can be increased and reduced, the lifting mechanism is arranged on the machine frame and can drive the bearing assembly to move up and down and make the bearing assembly fall in a moment, and the lifting mechanism can produce impact pulling force on the chain to be tested and the rope to be tested. Due to the fact that one end of the chain to be tested and one end of the rope to be tested are fixed on the fixing position, the other end of the chain to be tested and the other end of the rope to be tested are connected with the bearing assembly, the bearing assembly is driven by the lifting mechanism to move up and fall in a moment, and the falling bearing assembly produces the impact pulling force on the chain to be tested and the rope to be tested, the dynamic impact strength of the chain and the rope can be tested. The weight of the bearing assembly can be increased and reduced according to different chains and ropes. The testing jig is easy and reliable to operate, working intensity is reduced, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of strength testing, in particular to a fixture capable of testing the dynamic impact strength of chains and ropes. Background technique [0002] Today, with the development of science and technology, the preservation and safety of products have not only become the main indicators in product development and design, but also become an important standard to measure the quality of products. Especially for fixed products used in various occasions, such as protective chains and ropes that are more commonly used in the lighting industry. These protective chains and ropes are generally installed on the shell or outer cover of the lamp. When the product is repaired or parts are replaced, the protective chain and rope serve as a secondary protection, even if the installation part of the lamp fails and breaks, the lamp falls. Sometimes there will be a protective chain or rope to pull it, and it will not cause serious...
