Belt material of high temperature superconduct need be worked in liquid nitrogen, and when the radius-of-curvature of its bending during less than a certain numerical value, its performance will be degenerated.Belt material of high temperature superconduct bending property detection machine is used in and detects the radius-of-curvature of belt material of high temperature superconduct bending and the relation of its performance in the liquid nitrogen.Detection in the past is at ambient temperature, the pattern of choosing different radii detects belt material of high temperature superconduct to needs and carries out bending, and then put into liquid nitrogen and detect its characteristic, whenever choose a radius, sample will carry out a thermal cycle between room temperature and liquid nitrogen temperature.Such working method makes that test is very time-consuming, and is easy to cause the physical damage of sample when operation.At home and abroad yet there are no at present can once cool off after, the device of the feature measurement when in liquid nitrogen, belt material of high temperature superconduct being carried out different curvature radius.
Summary of the invention
For overcoming the shortcoming of prior art, the present invention proposes a kind of new belt material of high temperature superconduct bending property detection device, and it comprises parts such as structural framing, guiding mechanism, curvature cone pulley, back up pad.
Structural framing is rectangular shaped as frame structure, and it is worked at ambient temperature, is used for unit construction of the present invention together.The inboard on structural framing two long limits has groove.Guide runner is housed on the guiding mechanism, and the both sides of guide runner have tongue, and the groove of inboard, the long limit of structural framing two cooperates assembling with the both sides tongue of the guide runner of guiding mechanism, and guiding mechanism is packed in the structural framing.Guiding mechanism the guiding of guide runner under can in structural framing, move along its long limit.The minor face of structural framing is installed the curvature cone pulley with two downward back up pads of bolt in its lower end.
The guide runner of structural framing and guiding mechanism is operated at ambient temperature.By two back up pads of extending downwards the curvature cone pulley is fixed in the liquid nitrogen, use the tension adjustment bolt of guiding mechanism tested belt material of high temperature superconduct can be placed liquid nitrogen, by the adjustment bolt on the adjustment structural framing and the tension adjustment bolt of guiding mechanism, can be with the position of tested belt material of high temperature superconduct accurate in locating in required measurement curvature.Use the curvature cone pulley that different bending radius can be set, can measure the performance of belt material of high temperature superconduct when different bending radius.
The present invention is after one-step installation, and the characteristic when once cooling promptly can be easily carried out different curvature radius to belt material of high temperature superconduct in liquid nitrogen is measured.
Description of drawings
Fig. 1 is an embodiment of the invention structure front elevation;
Fig. 2 is an embodiment of the invention structure side view.
Among the figure: 1 is structural framing, and 2 is guiding mechanism, and 3 is the curvature cone pulley, and 4 is back up pad, and 5 is horizontal adjusting bolt, and 6 is guide runner, and 7 are the guiding clamping plate, and 8 for circle lacks the shape orienting lug, and 9 is the tension adjustment bolt, and 10 is liquid nitrogen surface.
Embodiment:
Further specify the present invention below in conjunction with the drawings and specific embodiments.
Back up pad 4 is two same parts, and its upper end is installed in respectively on two minor face inboards of structural framing 1, extends downwards, and curvature cone pulley 3 is equipped with in its lower end.
The course of work of the present invention is as follows:
During measurement, tested belt material of high temperature superconduct is installed at first at room temperature, is adjusted earlier a pair of horizontal adjusting bolt 5 on the structural framing 1, with the center fixation of guiding mechanism 2 above the face of cylinder of the maximum of curvature cone pulley 3.Again an end of tested belt material of high temperature superconduct is welded to the lower end of a tension adjustment bolt 9 of guiding mechanism 2, allow it extend downwards along the arc guide groove that a circle lacks shape orienting lug 8, walk around the face of cylinder of the maximum of curvature cone pulley 3, the arc guide groove that lacks shape orienting lug 8 along another circle extends upward the lower end that is connected to another tension adjustment bolt 9.Adjust the tension adjustment bolt 9 of guiding mechanism 2 then, guide tested belt material of high temperature superconduct and vertically move up, and add certain force of strain, fitted in the face of cylinder of the maximum of itself and curvature cone pulley 3.The Lower Half of the belt material of high temperature superconduct bending property detection machine of the present invention of the tested belt material of high temperature superconduct that installs is immersed in the liquid nitrogen, and its first half is in the room temperature.Can measure the characteristic of belt material of high temperature superconduct when the radius-of-curvature of the greatest circle cylinder of corresponding curvature cone pulley 3 this moment.
After this parameter measurement finishes, adjust the tension adjustment bolt 9 of guiding mechanism 2, guide tested belt material of high temperature superconduct and vertically move down, the face of cylinder when making tested belt material of high temperature superconduct utilize the elasticity of self to break away from measurement.Adjust a pair of horizontal adjusting bolt 5 then at ambient temperature, the center fixation of guiding mechanism 2 is carried out curvature cone pulley 3 required next parameter measurement curvature the corresponding face of cylinder above.Adjust the tension adjustment bolt 9 of guiding mechanism 2, guiding tested belt material of high temperature superconduct vertically moves up, and add certain force of strain, fitted in the required corresponding face of cylinder of curvature institute of carrying out next parameter measurement of itself and curvature cone pulley 3, can measure the characterisitic parameter of belt material of high temperature superconduct this moment when corresponding radius-of-curvature.Repeat this process, finish until measuring.Belt material of high temperature superconduct bending property detection machine of the present invention is taken out from liquid nitrogen, finish measurement.
In sum, the present invention is used in and detects the radius-of-curvature of belt material of high temperature superconduct bending and the relation of its performance in the liquid nitrogen.
The rectangular shaped as frame structure of structural framing 1 and the slide block of guiding mechanism 2 are operated at ambient temperature.By two back up pads 4 of extending downwards the curvature cone pulley is fixed in the liquid nitrogen, use the tension adjustment bolt 9 of guiding mechanism 2 tested belt material of high temperature superconduct can be placed liquid nitrogen, by the adjustment bolt 5 on the adjustment structural framing 1 and the tension adjustment bolt 9 of guiding mechanism, can be with the position of tested belt material of high temperature superconduct accurate in locating in required measurement curvature.Use curvature cone pulley 3 that different bending radius can be set, and measure the performance of belt material of high temperature superconduct when different bending radius.
