Connect.
Operation console below the sleeve slide is equipped with scale, and the scale is between the fixture and guide wheel
It is and parallel with the line of guide wheel with fixture.
The temperature range control of the sleeve is 20-200 DEG C.
Compared with prior art, the beneficial effects of the utility model are：
The utility model controls the tension force suffered by cord fabric thread by the counterweight of different quality, and cord is replaced with the gravity of counterweight
The tension force of clamping simultaneously keeps tension stability suffered by cord fabric thread in test process, is heated using heating unit to sleeve, carries out cord
Croop property is tested, and can be used to test croop property of the cord fabric thread under different stress, different temperatures；The utility model utilizes weight
Code is used as loading device, and when the creep and stress rupture test time is longer, its power saving advantages is especially pronounced, therefore the present apparatus is in long creep
There is more wide application prospect in the croop property experiment in service life；Not only equipment cost is relatively low for the utility model, stress model
Enclose extensively, and multigroup parallel test can be carried out every time, multiple samples can be tested at the same time, greatly improve testing efficiency, save
Test the time it takes.

Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings：
A kind of creep testing machine, including rack 1, the rack 1 are fixedly arranged above operation console 2, and the top of operation console 2 is set
There is sleeve slide 11, the sleeve slide 11 is fixedly arranged above sleeve 4, and heater 10 is equipped with the sleeve 4, and the sleeve is slided
The both sides of rail 11 are respectively equipped with some fixtures 3 and guide wheel 5, and the fixture 3 is identical with the number of guide wheel 5 and both straight lines for being linked to be
It is mutually perpendicular to sleeve slide 11, the guide wheel 5 is arranged right below counterweight 6, and the lower section of the counterweight 6 is equipped with lifting platform 7, institute
The side that lifting platform 7 is fixed on the rack 1 is stated, controller 8, the heater 10, lifting platform are further fixed in the rack 1
7 and sleeve slide 11 couple with 8 electric control of controller.
Operation console 2 positioned at the lower section of sleeve slide 11 is equipped with scale 9, and the scale 9 is located at the fixture 3 with leading
