Belong to material under the high temperature conditions, it is very universal to occur apparent creep, and creep may cause serious consequence.For example,
The high-temerature creep of the boiler tube of boiler can cause boiler tube diameter to increase, wall thickness reduction, even result in boiler tube explosion.So generally
In the case of, new high-temperature alloy material is before practical application, it should carry out high-temerature creep experiment.High-temerature creep is tested compacted
Become on testing machine and carry out.Existing creep testing machine has electronic type and mechanical two types, wherein electronic type creep testing machine
The power of motor is converted into active force using transmission device to be applied on test specimen, existing deficiency is complicated, valency
Lattice are expensive；Mechanical creep testing machine is acted on after using lever mechanism, the gravity of counterweight is amplified on test specimen, this creep examination
It is simple in structure to test machine, price is relatively low, but there are following deficiencies：After creep elongation occurs for test specimen, counterweight moves down, and lever deviates water
Prosposition is put, and the active force suffered by test specimen deviates the original direction vertical with ground, and result of the test error is caused to increase, if
Increase lever levelling gear, can so that structure is very complicated, in addition, lever mechanism structure is larger so that testing machine occupied space compared with
Greatly.
Utility model content
In order to overcome the above-mentioned deficiency of the prior art, the utility model provides a kind of high temperature alloy creep testing machine, the examination
Gravity of the machine using gear mechanism amplification counterweight is tested, can ensure the direction for the active force that test specimen is subject to during entire experiment
It is constant, significantly improve the precision of creep testing machine result of the test.
Following technical proposal can be used to realize in the above-mentioned purpose of the utility model：A kind of high temperature alloy creep testing machine,
The high temperature furnace of lower collet is fixed with including substrate, head tree, top plate, bottom, the substrate and top plate are fixedly connected on the master
The both ends of column, the high temperature furnace are fixedly connected on the substrate, wherein, further include the tooth being fixedly connected on the top plate
Wheel decelerator, is fixedly connected with output sheave on the output shaft of the gear reduction unit, on the input shaft of the gear reduction unit
It is fixedly connected with input sheave；The output sheave is intertwined and connected and has upper drawstring, and one end of the upper drawstring is connected with polished rod；
The polished rod passes through the guide sleeve being fixed on high temperature furnace and is fixedly connected with upper grip；The input sheave is intertwined and connected and has
Lower drawstring, one end of the lower drawstring are connected with counterweight；Specimen holder is between upper grip and lower collet.
Preferably, point of contact, upper grip and the lower collet of output sheave and the upper drawstring be on the same line.
Preferably, the guide sleeve and the polished rod clearance fit.
The utility model has the advantage that compared with prior art：Since the testing machine is using gear mechanism amplification weight
Code gravity loads test specimen using sheave and upper drawstring is exported, eliminates lever levelling problems, it is ensured that experiment process pilot scale
The Impact direction of part is constant, in the case where manufacture cost does not significantly improve, significantly improves the precision of result of the test；Separately
Outside, due to eliminating lever, the size of testing machine is obviously reduced, and saves experiment floor space.
