Abstract

The invention provides a test object connection device of a mechanical fatigue testing machine. The device comprises a rotating mechanism, a pushing rod and a sensor, wherein the rotating mechanism isarranged between the pushing rod and the sensor, and the rotating mechanism is used for driving the sensor to rotate up and down around the pushing rod. Compared with the prior art, a sensor supportand a connecting rod are hinged through a hinge pin; and when the fatigue testing machine is used to perform a fatigue performance test on a test object, a pushing head is perpendicular to the test object all the time due to hinged connection, the force measured by the sensor is force actually acting on the test object, therefore, a measurement error is avoided, and the accuracy of test data is greatly improved.

Description

technical field [0001] The invention relates to the technical field of connecting devices, in particular to a connecting device for a test product of a mechanical fatigue testing machine. Background technique [0002] Surge arrester is a kind of power primary equipment used to protect power transmission and transformation equipment in the power system from lightning overvoltage and operating overvoltage damage. The lightning arresters in the power station are mostly installed on the brackets, and must bear the bending moment force caused by the top load and wind pressure. Therefore, the bending load must be assessed during the type test, which is also the most important item in the type test project. It is mainly used to confirm the bending load capacity and bending failure strength of the arrester under the test conditions. [0003] At present, there are very few equipments for mechanical fatigue testing of arresters at home and abroad, and even the equipment produced by a...
