Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, specifically to an experimental support for a high-temperature aging chamber. Background Technology

[0002] The testing of wires and cables includes a heat shrinkage test, which utilizes the rapid heating of equipment to test the cables and determine their performance stability. This requires wrapping the ends of the sample with wire and then suspending it in a suitable position on a wire mesh frame to ensure uniform heating. Currently, high-temperature aging chambers are not equipped with corresponding experimental supports for heat shrinkage testing. Operators must wear thick gloves and operate the equipment directly. They must withstand the temperature while suspending the wire on the wire mesh frame before conducting the test. Furthermore, during and after the heating and aging process, operators need to remove the sample from the wire for measurement. Overall, the operation is high-risk and cumbersome.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figure 1This utility model provides an experimental support for a high-temperature aging chamber, including a base 1. First grooves 2 are respectively formed on both sides of the upper surface of the base 1 near the edge. A first slider 3 is slidably disposed in each first groove 2, and a support plate 4 is fixedly connected to the top of the first slider 3. Several measuring devices 5 are disposed between two support plates 4. Each measuring device 5 includes a measuring ruler 6 and two support frames 7. Each support frame 7 is sleeved on the outside of the support plate 4, and limit plates 8 are fixedly connected to both sides of each support frame 7. First limit bolts 9 pass through the limit plates 8 and abut against both sides of the support plate 4. The first limit bolts 9 are used to restrict the mutual movement of the support frame 7 and the support plate 4. The test involves two support frames 7 positioned on the same plane, with a measuring ruler 6 fixedly connected between them. Each support frame 7 has a fixed hanging ring 10, with the two hanging rings 10 positioned opposite each other and between the two support frames 7. The line connecting the two hanging rings 10 is parallel to the measuring ruler 6. The support frames 7 are positioned on both sides of the support plate 4 and are parallel to each other. During the test, the insulation of both ends of the sample is stripped, and the internal metal cable is wound around the two hanging rings 10 on the support frame 7. This ensures that the cable sheath on the sample between the two hanging rings is not connected to the hanging rings and that the sample is fully supported and will not slip. After reaching the standard temperature and time, the change in the cable sheath between the two hanging rings is read using the measuring ruler 6. The horizontal cross-section of the support frame 7 is a rectangular ring with one open end, the open end of which is away from the hanging ring 10. The horizontal cross-section of the support plate 4 is rectangular. The support frame 7 is positioned on both sides of the limiting plate 8 and abuts against both sides of the support plate 4 to prevent the support frame 7 from shaking. The added experimental support can hold multiple sets of samples for testing; the measuring scale on the support allows for real-time observation of sample dimensions as temperature changes; the support has a base, preventing tipping and facilitating placement during testing. The combination of the base 1, the first sliding groove 2, the first slider 3, and the support plate 4 allows for easy adjustment of the distance between the two support plates 4, accommodating samples of different lengths. The inclusion of several measuring devices 5 means that multiple samples can be tested simultaneously, significantly improving testing efficiency.

[0021] See Figure 2In this embodiment of the invention, a lead screw 11 is fixedly connected to the connection between the support frame 7 and the hanging ring 10. The lead screw 11, the hanging ring 10, and the support frame 7 form a cross structure, with the two lead screws 11 facing away from each other. The support plate 4 has a second sliding groove 12, which is vertically formed. The top of the second sliding groove 12 communicates with the outside. Each lead screw 11 passes through the second sliding groove 12 and is slidably disposed within it. Two nuts 13 are threaded onto each lead screw 11, and the two nuts 13 are disposed on both sides of the support plate 4 and are used to clamp the support plate 4. The support frame 7 and the support plate 4 are fixedly connected by the two nuts 13 and the lead screw 11 to prevent the support frame 7 from falling off during the experiment. The lead screw 11 is fixedly connected to the connection between the support frame 7 and the hanging ring 10. The lead screw 11 passes through the second sliding groove 12 on the support plate 4 and is clamped by the nuts 13. This connection method between the lead screw 11 and the nut 13 provides stronger fastening force compared to simple contact or fixation, effectively avoiding the risk of the support frame 7 loosening or falling off under high temperature or vibration environments. The cross structure formed by the lead screw 11, the hanging ring 10, and the support frame 7, as well as the back-to-back arrangement of the two lead screws 11, helps to distribute stress and enhances the structural strength and stability of the hanging ring 10. The lead screw 11 slides within the second groove 12, and in conjunction with the nut 13, allows for fine-tuning of the vertical position of the support frame 7 to accommodate samples of different thicknesses or shapes. The lead screw 11 is preferably made of a nickel-based high-temperature alloy, and the nut 13 is preferably made of graphite-impregnated nickel alloy or silicon carbide ceramic.

[0022] In an embodiment of this utility model, a third sliding groove 22 is respectively provided on one side of each of the two supporting plates 4 facing each other, and the third sliding groove 22 communicates with the second sliding groove 12; a plurality of second sliders 14 are slidably disposed in the third sliding groove 22, and each lead screw 11 passes through the second slider 14, the second slider 14 being disposed between the nut 13 and the supporting plate 4; a washer 15 is provided on the side of the supporting plate 4 away from the slider, the washer 15 passing through the lead screw 11, the washer 15 being disposed between the nut 13 and the supporting plate 4. The friction between the slider and the washer 15 is increased, thereby improving the clamping capacity of the nut 13.

[0023] A third groove 22 is formed on the support plate 4, and the lead screw 11 passes through the second slider 14 within the third groove 22. This further enhances the horizontal stability of the support frame 7, preventing torsion or lateral displacement. The second slider 14 and the washer 15 are positioned between the two nuts 13 and the support plate 4, increasing the contact area and thus improving friction. This makes the nuts 13 more secure and less prone to loosening due to vibration or thermal expansion and contraction, ensuring reliability during long-term testing. The washer 15 can be made of flexible graphite or high-temperature alloy.

[0024] See Figure 3 As an optional embodiment, each of the first slide grooves 2 has a fourth slide groove 16 at its bottom, and a third slide groove 17 is fixedly connected to the bottom of the first slider 3; the third slide groove 17 is slidably disposed in the fourth slide groove 16; the third slide groove 17 matches the fourth slide groove 16; a fifth slide groove 18 is respectively provided on the side wall of each of the first slide grooves 2 near the other first slide groove 2, and a fourth slide groove 19 is fixed on one side of each of the first sliders 3, each fourth slide groove 19 is slidably disposed in the fifth slide groove 18, and each fourth slide groove 19 matches the fifth slide groove 18.

[0025] As an implementable example, both the third slider 17 and the fourth slide groove 16 are T-shaped sliders, and the fourth slide groove and the fifth slide groove 18 are T-shaped slide grooves. The T-shaped sliders on the bottom and sides prevent the support plate 4 from tilting. The two T-shaped third sliders 17 and 19 can securely hold the first slider 3 within the first slide groove 2, preventing the support plate 4 from tipping over due to its high center of gravity. To prevent the support plate 4 from tilting (bottom constraint): a fourth slide groove 16 is opened at the bottom of the first slide groove 2, and the bottom of the first slider 3 is fixedly connected to the third slider 17, which slides within the fourth slide groove 16. If a matching T-shaped slider and T-shaped slide groove are used, the vertical tilting or flipping of the first slider 3 can be effectively limited, thereby preventing the support plate 4 from tilting due to uneven force or a shift in the center of gravity.

[0026] A fifth groove 18 is formed on one side of the first groove 2, and a fourth slider 19 is fixed to one side of the first slider 3. The fourth slider 19 slides within the fifth groove 18. Similarly, the T-shaped structure can limit the lateral swaying of the first slider 3. The T-shaped sliders on the bottom and sides cooperate with the grooves to more firmly lock the first slider 3 into the first groove 2, significantly improving the overall stability of the support plate 4. Especially when the support plate 4 itself has a high center of gravity or carries a large number of samples, it can effectively prevent tipping.

[0027] In one possible implementation in practical use, each of the first sliders 3 is fixedly connected to the support at its top with a triangular support frame 20. The lower surface of the triangular support frame 20 abuts against the upper surface of the base. The two triangular support frames 20 are arranged opposite to each other between the two support plates 4. The triangular support frame 20, the third slider 17 and the fourth slider 19 cooperate to prevent the support plate 4 from failing to support due to thermal expansion and contraction.

[0028] In one possible implementation for practical use, each of the triangular support frames 20 has a vertically threaded hole, and a second limiting bolt 21 is installed in the threaded hole. The bottom of the second limiting bolt 21 is used to abut against the upper surface of the base 1. The triangular support frame 20 is fixedly connected to the top of each first slider 3 at the connection with the support plate 4, and its lower surface abuts against the upper surface of the base 1. Triangles have stability, and this design uses the triangular support frame 20 to provide additional support points, directly transferring part of the load of the support plate 4 to the base 1. This can effectively distribute the pressure of the first slider 3, especially in high-temperature environments where thermal expansion and contraction of materials may lead to changes in the fit clearance or stress concentration. The triangular support frame 20 can better maintain the stability of the support plate 4, preventing it from failing to support due to deformation or loose connection. The triangular support frame 20 has a threaded hole and is equipped with a second limiting bolt 21, the bottom of which abuts against the upper surface of the base 1. This is equivalent to locking the triangular support frame 20 and indirectly the support plate 4 to the base 1 with bolts, further restricting their relative movement, improving the support capacity of the triangular support frame 20 for the support plate 4 and the rigidity of the overall structure, and preventing displacement caused by accidental collisions or vibrations.

[0029] The slider is made of high-temperature alloy, silicon carbide, or silicon nitride; the groove is preferably made of a metal substrate with a ceramic coating.
