Test device of disc spring shock absorber

Abstract

The invention discloses a test device of a disc spring shock absorber. The test device comprises an installation base, a fixing part, a supporting part, a lifting part and a measuring part, wherein the disc spring damper is fixed on the installation base through the fixing part; the supporting part is erected on the installation base; the lifting part is arranged on the supporting part and comprises a rotating shaft, an operating handle and a steel wire rope, wherein the rotating shaft is arranged on the supporting part through a support, the operating handle and a non-return mechanism are arranged on the rotating shaft, the steel wire rope with adjustable winding length is wound on the rotating shaft, and the lower end of the steel wire rope is connected with a pull rod of the disc springdamper; and the measuring part comprises a force measuring device and a length measuring device, the force measuring device is in signal connection with a signal detection device in the disc spring damper, and the length measuring device is arranged on the pull rod of the disc spring damper. According the the test device of a disc spring shock absorber, the special test requirement of the disc spring bumper shock absorber can be satisfied, and the test device has a simple and efficient structure, does not need driving equipment such as electricity or hydraulic pressure and the like, and solves the limitation of a specific environment required by the test.

Description

technical field [0001] The invention relates to an equipment test device, in particular to a test device for a disc spring shock absorber. Background technique [0002] When the inner rod of the high temperature gas-cooled reactor control rod drive mechanism drives the chain down, the disc spring shock absorber provides buffering, shock absorption and suspension for the inner rod and the chain. The bottom of the disc spring shock absorber is equipped with a trigger sensor. When the internal disc spring compression exceeds the set value, the sensor triggers and feeds back the signal. Due to the influence of disc spring size tolerance and performance difference, when the disc spring shock absorber is pulled, the The tensile force corresponding to the compression amount of the stacked disc springs is inconsistent, and the disc spring shock absorber, sensor and compression amount need to be adjusted experimentally. [0003] At present, the tensile test of equipment is mainly ca...

AI Technical Summary

Problems solved by technology

[0003] At present, the tensile test of equipment is mainly carried out by special tensile testing machine. Not only the initial investment cost is high, but also the test range for products with specific structures is limited. Therefore, it needs to be designed in combination with the special structure of the disc spring shock absorber. A new test device
