[0040] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0041] Embodiment 1

[0042] like Figure 1 As shown, a high temperature environment conductor tensile testing machine comprises:

[0043] A tensile testing machine 1, the tensile testing machine 1 comprising a stand, a fixing portion 11, a tensile portion 12, and a joining assembly 13 arranged on the tensile portion 12 and the fixing portion 11;

[0044] A bearing mechanism 2, which is arranged on one side of the frame of the tensile testing machine 1 and is used to fix and move the conductor for tensile testing. The bearing mechanism 2 includes a fixed component 21 and a movable component 22;

[0045] A heat preservation mechanism 3, which is arranged on the tensile testing machine 1 and is used to provide a high temperature environment for the conductor tensile test;

[0046] The heat insulating mechanism 4 is arranged in the heat preservation mechanism 3 and is used to reduce the heat loss in the heat preservation mechanism 3.

[0047] In this embodiment, by providing a bearing mechanism 2 and a heat preservation mechanism 3, efficient testing of the conductor in a high temperature environment is achieved. The conductor is fixed by the bearing mechanism 2 to reduce the frequency of manual fixing during multiple tests. The heat preservation mechanism 3 provides a high temperature environment for the conductor test. By cooperating with the bearing mechanism 2, the number of fixing openings and closings can be reduced, thereby avoiding heat loss and time waste caused by repeated fixing of the conductor during multiple tests.

[0048] In detail, one end of the conductor is manually fixed on the moving component 22, the moving component 22 fixes the conductor segments on the fixing component 21, and the fixing component 21 rotates to send the conductor segments into the heat preservation mechanism 3. The conductor is tested by the joint component 13, and the conductor is output after the test is completed. During the movement of the conductor, the temperature is increased and stabilized by the heat preservation mechanism 3 and the heat insulation mechanism 4, providing a stable high temperature environment for the detection of the conductor.

[0049] It should be noted that, for the test of the conductor, the device fixes a longer conductor sample on the supporting mechanism 2, and fixes the conductor in multiple sections, and tests each section of the conductor, thereby realizing multiple tests on the conductor.

[0050] It is worth mentioning that through multi-section testing of the conductor, the temperature in the insulation box 31 can be easily adjusted, avoiding heat loss caused by the need to replace and fix the conductor when testing the conductor in different temperature environments, so that the temperature of the test environment can be increased linearly and maintained stable.

[0051] Further, if Figure 2 , Figure 5As shown, the fixing assembly 21 includes a central frame 211 arranged on a stand, two groups of rotating rings 212 rotatably connected to the central frame 211 and driven by a motor, multiple groups of extension rods 213 symmetrically arranged on the two groups of rotating rings 212, first spring clips 214 arranged at the ends of the extension rods 213, fasteners 215 fixed to the extension rods 213 by the first spring clips 214, and a rotating shaft 216 rotatably connected to both sides of the heat preservation mechanism 3 and rotating synchronously with the rotating rings 212 through a transmission belt.

[0052] In this embodiment, the conductor is fixed by setting a rotating ring 212 and an extension rod 213 in cooperation with a fastener 215. The conductor is fixed to the end of the extension rod 213 by the fastener 215. Each extension rod 213 is used as a node to fix the conductor once, so that the conductor located between the two extension rods 213 becomes an independent detection section for subsequent detection.

[0053] In detail, the longer conductor is fixed to the end of the extension rod 213 by using the fastener 215, and the conductor is moved by rotating the rotating ring 212, so that each section of the conductor is moved to the heat preservation mechanism 3 in turn for testing.

[0054] It should be noted that the conductor length is selected according to the needs so that the conductor can be divided into a required number of sections according to the test requirements, such as three or four sections, so that the conductor can be tested three or four times.

[0055] The rotating ring 212 drives the central shaft 216 to rotate synchronously, and when the rotating ring 212 rotates by the angle between the two extension rods 213 , the central shaft 216 rotates one circle.

[0056] It is worth mentioning that the fastener 215 is fixed by a spring clip. On the one hand, the fastener 215 can be fixed to the end of the extension rod 213, and on the other hand, it is easy to disassemble the fastener 215 and facilitate the subsequent tensile test.

[0057] Further, if Figure 3 , Figure 6 As shown, the fastener 215 includes a clamping rod 2151 for facilitating clamping by a spring clip, a winding rod 2152 arranged in the middle of the clamping rod 2151, a winding ring 2153 rotatably connected to the clamping rod 2151 on the outside of the winding tube and driven by a motor, and a plurality of clamping blocks 2154 fixedly connected to the winding ring 2153 and driven by an electric cylinder.

[0058] In this embodiment, the conductor is fixed to the fastener 215 by providing the winding rod 2152 and the pressing block 2154, so as to prevent the conductor from slipping or falling off during the subsequent test process, thereby affecting the test.

[0059] In detail, when the conductor is placed on one side of the winding rod 2152, one group of clamping blocks 2154 moves, so that the conductor can fit on the winding rod 2152 without affecting the relative sliding between the clamping blocks 2154 and the conductor, that is, the clamping blocks 2154 form a certain constraint on the conductor, and the conductor is placed off the winding rod 2152. Then the winding ring 2153 drives all the clamping blocks 2154 to rotate. While the clamping blocks 2154 rotate, the conductor is wound around the winding rod 2152 in a circle, and then all the clamping blocks 2154 are tightened to fix the conductor on the winding rod 2152.

[0060] It should be noted that, by setting the winding rod 2152, the conductor can be pressed against the winding rod 2152 after being wound once, thereby increasing the stability of the conductor fixation and preventing the conductor from slipping or falling off in subsequent tensile tests.

[0061] Further, if Figure 4 , Figure 5 As shown, the moving assembly 22 includes a traction rod 221 connected to the center frame 211 through a motor rotation, a first clamping jaw 222 arranged on the upper side of the end of the traction rod 221 and controlled by an electric cylinder to move a short distance, a slide groove 223 arranged on the lower side of the traction rod 221, and a second clamping jaw 224 slidably connected to the slide groove 223 and driven by a linear motor;

[0062] It also includes a collecting tank 225 which is arranged on the central frame 211 in a vertical sliding connection and is connected to the rotating shaft of the traction rod 221 through a gear rack transmission method.

[0063] In this embodiment, the conductor is pulled by providing the pulling rod 221 , the first clamping jaw 222 and the second clamping jaw 224 , thereby fixing the conductor in cooperation with the fastener 215 .

[0064] In detail, the conductor is manually passed through the first clamp 222 and the second clamp 224, and the end of the conductor is fixed by the first clamp 222 and the second clamp 224. The two clamps are set at a certain distance to facilitate the winding rod 2152 and the clamping block 2154 to clamp and fix. Then the second clamp 224 is released. After the fastener 215 is wound and clamped, the inner circle of the conductor is clamped by the clamping block 2154, and the outer circle wraps around the fastener 215 and returns to the vicinity of the second clamp 224. The second clamp 224 grabs the twisted conductor and moves along the slide groove 223 to pull the excess section of the conductor through the fastener 215. Then the first clamp 222 and the second clamp 224 release the conductor, the traction rod 221 rotates, and the first clamp 222 retracts to avoid the fastener 215 under the control of the electric cylinder, and then the conductor is clamped again. The traction rod 221 moves to the position of the next fastener 215 and is fixed again.

[0065] At the same time, as the traction rod 221 rotates, the collecting tank 225 is driven to rise. The collecting tank 225 is used to collect the conductor fragments after the test is completed.

[0066] It should be noted that the gap between the first jaw 222 and the second jaw 224 should be slightly larger than the diameter of the conductor, so that when the two jaws clamp the conductor, the conductor can be prevented from falling off completely freely. When the traction rod 221 rotates and the second jaw 224 slides, the conductor can slide smoothly in the jaws.

[0067] It is worth mentioning that a gear is provided on the rotating shaft of the traction rod 221, and the collecting tank 225 is vertically slidably connected to the central frame 211 and a rack is provided below. The collecting tank 225 is raised by the meshing of the gear and the rack.

[0068] Further, if Figure 7 As shown, the heat preservation mechanism 3 includes a heat preservation box 31 which is arranged on a stand and accommodates the fixing part 11, the stretching part 12 and the coupling assembly 13 and is provided with an opening on the side facing the supporting mechanism 2, a heat source 32 arranged at the bottom of the heat preservation box 31, an air outlet 33 rotatably connected above the heat source, an arc-shaped heat collecting plate 34 arranged in the middle of the heat preservation box 31, a slide bar 35 horizontally slidably connected to the side wall of the heat preservation box 31 and used to fix the arc-shaped heat collecting plate 34, a control shaft 36 which drives the air outlet 33 to rotate through a gear and is connected to the slide bar 35 through a gear rack transmission method, and the transfer shaft 216 drives the control shaft 36 through a gear rack transmission method.

[0069] In this embodiment, the air outlet 33 and the arc-shaped heat collecting plate 34 are provided to create a high-temperature environment for the conductor, so that the conductor is in a relatively constant high-temperature environment during the test process.

[0070] In detail, when the rotating ring 212 rotates to move the conductor into the insulation box 31, the air outlet 33 faces the test position of the insulation box 31, that is, it is facing the conductor. As the conductor rotates and moves upward, the air outlet 33 rotates and the arc-shaped heat collecting plates 34 approach each other. After the conductor moves to the test position, the air outlet 33 faces the middle of the arc-shaped heat collecting plate 34, and the arc-shaped heat collecting plate 34 forms a heat collecting air duct, so that the conductor can heat up quickly and keep the temperature stable. After the test is completed, the arc-shaped heat collecting plate 34 moves away to avoid interfering with the removal of the conductor.

[0071] It should be noted that the outer end of the control shaft 36 is fixedly connected to two sets of racks arranged opposite to each other, and incomplete gears are meshed inside the racks. The transfer shaft 216 drives the incomplete gears through bevel gears, thereby driving the household heat collecting plate to move.

[0072] It is worth mentioning that the arc-shaped heat collecting plate 34 can make the temperature around the conductor rise rapidly and remain stable during the tensile test. The arc-shaped heat collecting plate 34 moves closer and farther away to make the hot air flow, so that the temperature of the insulation box 31 can converge as soon as possible, avoiding excessive temperature difference in the insulation box 31.

[0073] Further, if Figure 8 As shown, the coupling assembly 13 includes a fixing member 131 arranged on the fixing portion 11 and a stretching member 132 arranged on the stretching portion 12, the fixing member 131 includes a lever 1311 arranged at the bottom and rotatably connected to the fixing portion 11, a torsion spring arranged on the rotating shaft of the lever 1311, a fixing hook 1312 arranged at the bottom and rotatably connected to the fixing portion 11, and the fixing hook 1312 is meshed with the rotating shaft of the lever 1311 through gears.

[0074] In this embodiment, the fastener 215 is fixed by providing the lever 1311 and the stretching portion 12, so that one end of the conductor to be tested is fixed, and the other end is stretched to complete the test.

[0075] In detail, when the conductor is subjected to a tensile test, the lower end of the conductor is fixed and the upper end is stretched. When the conductor is rotated, the fastener 215 contacts the lever 1311, and the lever 1311 is moved. The lever 1311 rotates and drives the fixing hook 1312 to rotate at the same time. As the fastener 215 and the fixing hook 1312 rotate, the fixing hook 1312 hooks the fastener 215 to fix the fastener 215.

[0076] It should be noted that when the fastener 215 is hooked by the fixing hook 1312, the upper end of the lever 1311 contacts the fastener 215. When the fastener 215 needs to continue to move, the fixing hook 1312 can follow the fastener 215 to rotate at a certain angle. At this time, the lever 1311 disengages from the fastener 215 and resets under the action of the torsion spring. The fixing hook 1312 then disengages from the fastener 215, and the fastener 215 can continue to move upward.

[0077] Further, if Fig. 9 As shown, the stretching member 132 includes an inclined rail 1321 arranged on the stretching part 12, a slider 1322 slidably connected to the inclined rail 1321 and driven by a telescopic cylinder, a second spring clip 1323 arranged on the inner side of the slider 1322, a receiving rod 1324 rotatably connected to the middle of the inclined rail 1321, and a force groove 1325 arranged on the receiving rod 1324.

[0078] In this embodiment, the fastener 215 is transferred and fixed by providing a slider 1322 and a force groove 1325 .

[0079] In detail, as the fastener 215 rotates upward, the fastener 215 moves into the second spring clip 1323, the clamping rod 2151 is clamped by the second spring clip 1323, the slider 1322 moves to make the fastener 215 disengage from the first spring clip 214 and move upward, the slider 1322 moves upward to fix the fastener 215 on the stress groove 1325, and perform subsequent tensile testing.

[0080] It should be noted that after the fixing member 131 and the stretching member 132 fix the two ends of the conductor, the stretching part 12 of the tensile testing machine 1 moves up to perform a tensile test. The tensile test of the conductor is used to test the maximum tensile strength of the conductor. After the test is completed, the conductor is in a broken state. At this time, the fastener 215 is detached from the extension rod 213 and will not affect the movement of the conductor. During the test, the force groove 1325 shares part of the pressure of the fastener 215 to prevent the slider 1322 from sliding.

[0081] It is worth mentioning that when the rotating ring 212 stops rotating, the conductor is in a tilted state in the heat preservation box 31. After the fastener 215 is moved into place by the slider 1322, the conductor is in a vertical state and can be tested.

[0082] Further, if Fig.10 As shown, the insulation mechanism 4 includes a partition 41 fixedly connected to the center rod, an isolation component 42 arranged at the upper and lower ends of the partition 41, and a filling component 43 arranged at the left and right sides of the partition 41, the isolation component 42 includes an insulation plate 421 respectively arranged at the upper and lower ends of the partition 41 and vertically slidably connected to the inner wall of the insulation box 31, a screw rod 422 rotatably connected to the side wall of the insulation box 31 and threadedly connected to the insulation plate 421, a driving shaft 423 rotatably connected to both sides of the insulation box 31 and driving the screw rod 422 through a worm gear transmission method, and a driving member 424 arranged on the outside of the insulation box 31 for driving the driving shaft 423 to rotate.

[0083] In this embodiment, by providing a partition 41 and an isolation assembly 42, thermal insulation is achieved at the upper and lower ends of the opening of the thermal insulation box 31, preventing heat loss while avoiding affecting the movement of the fastener 215 in and out.

[0084] In detail, the drive shaft 423 rotates to drive the screw rod 422 to rotate, and the screw rod 422 causes the insulation board 421 to slide up and down. When the fastener 215 moves out of the insulation box 31, the upper insulation board 421 moves up first, and then the insulation board 421 moves down and back to its original position after the fastener 215 is moved out. Similarly, when the fastener 215 enters the insulation box 31 from below, the insulation board 421 at the bottom moves down first and then moves up and back to its original position.

[0085] It should be noted that the heat insulation board 421 is tightly attached to the inner wall of the heat preservation box 31 to insulate the heat.

[0086] Further, if Fig.11 As shown, the driving member 424 includes a driving gear 4241 arranged at the outer end of the driving shaft 423, a driving gear ring 4242 connected to the rotating shaft 216 through a transmission belt and used to drive the driving gear 4241 to rotate, and the driving gear 4241 is provided with internal teeth and external teeth for driving the driving gear 4241 to perform periodic forward and reverse rotation.

[0087] In this embodiment, the driving gear ring 4242 is provided to realize the mutual correlation between the movement of the heat insulation plate 421 and the movement of the fastener 215, so as to realize the matching between the moving position of the fastener 215 and the opening and closing of the heat insulation plate 421.

[0088] In detail, the transfer shaft 216 drives the driving gear ring 4242 through the transmission belt, and the driving gear ring 4242 drives the driving gear 4241 and the driving shaft 423 to rotate. The internal teeth and external teeth set on the driving gear ring 4242 can make the driving shaft 423 rotate forward and reverse. When the fastener 215 approaches, it is opened by forward rotation, and when the fastener 215 moves away, it is closed by reverse rotation.

[0089] Further, if Fig.12 As shown, the filling component 43 is provided with two groups respectively located on both sides of the partition 41, and each group of filling components 43 includes two groups of annular belts 431 arranged on the edges of the partition 41 and the insulation box 31 and driven by a motor, insulation cotton 432 wrapped on the outside of the annular belt 431 and contact grooves 433 arranged on the insulation cotton 432.

[0090] In this embodiment, the gaps on both sides of the partition 41 are blocked by providing an annular belt 431 and a heat insulating cotton 432 to prevent a large amount of heat from overflowing from both sides of the partition 41 .

[0091] In detail, the annular belt 431 rotates synchronously with the rotating ring 212. When the extension rod 213 is extended into the heat preservation box 31, the back surfaces on both sides are fitted together and then put together. At this time, the extension rod 213 is located in the contact groove 433, and the extension rod 213 is wrapped. The heat insulation cotton 432 on both sides fits tightly to isolate the heat from dissipating and moves upward with the extension rod 213.

[0092] It should be noted that the heat insulation cotton 432 adopts glass fiber heat insulation material, which has good heat insulation performance and certain flexibility, and can be squeezed against each other to avoid the formation of pores.

[0093] It is worth mentioning that the extension rod 213 can be wrapped by the heat insulation cotton 432, which does not affect the movement of the extension rod 213 and forms a good heat insulation effect.
