Outage test sample protection device of creep deformation machine

Abstract

The invention provides an outage test sample protection device of a creep deformation machine and relates to a testing machine protection device. The outage test sample protection device is formed by a lever mechanism, a guide mechanism, a screw rod mechanism, a buffering mechanism and an electromagnet mechanism, and comprises a loading weight tray, a guide rod, a hoisting screw rod, a lever, a counter weight, an electromagnet and an buffering air barrel, wherein the two ends of the lever mechanism are respectively provided with a loading weight and the counter weight; the guide mechanism is used for fixing the tray at the end of the loading weight and the buffering mechanism is provided with the counter weight; the loading weight tray is connected onto the guide rod; the middle part of the lever is hinged onto the hoisting screw rod; one end of the lever is connected with a hinge joint and the other end of the lever is hinged onto a vertical rod of the counter weight; and one end of the vertical rod of the counter weight is connected into the buffering air barrel. The device utilizes the weight of the counter weight to enable the tray at the other end of the lever to move upwards so that the loading weight is supported and a test sample is protected; and therefore, the weight of the creep deformation machine is supported in accidental power failure, so that an alloy test sample can be freely condensed under a non-load condition, and the abnormal cracking of the alloy test sample can be effectively avoided.

Description

technical field [0001] The invention relates to a testing machine protection device, in particular to a creep machine power-off sample protection device. Background technique [0002] For superalloys, the high temperature and stress conditions selected in the experiment generally enable the alloy to have a creep life of 200-500 hours, and sometimes the duration of the creep experiment can even be as long as tens of thousands of hours according to the needs. Therefore, it is necessary to The variable testing machine works continuously for a long time. Once the power is cut off, the sample will break due to the rapid drop of the ambient temperature, which will make the creep experiment fall short and bring huge economic and scientific losses. Contents of the invention [0003] The purpose of the present invention is to provide a creep machine power-off sample protection device, which uses the weight of the breeding weight to move the tray at the other end of the lever upwar...
