Description

Technical Field

[0001] This invention relates to the field of electric heat tracing technology, and in particular to a device for testing the bending performance of electric heat tracing. Background Technology

[0002] Electric heating tape is an electric heating element used to provide heat. It is widely used to maintain the temperature of pipes, containers, or equipment, prevent freezing, or ensure the temperature stability of fluids. Its operation involves generating heat by passing an electric current through a strip of resistive material, thereby providing warmth to the object requiring insulation. Electric heating tape bending performance testing devices are mainly used to test the performance and durability of electric heating tapes under bending conditions, ensuring that they can maintain normal operation during actual use and avoiding damage or performance degradation. This device allows for a comprehensive evaluation of the bending performance of electric heating tapes, ensuring that they can adapt to various complex pipe shapes and installation environments in practical applications.

[0003] However, it still has some shortcomings. Most electric heating cable bending performance testing devices can only test electric heating cables of the same specification. Moreover, if the bending degree of the electric heating cable needs to be changed during the test, the position of the electric heating cable must be manually adjusted after the test, which makes the testing efficiency low. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a device for testing the bending performance of electric heating cables, so as to solve the problem that existing electric heating cable testing devices have fixed specifications for testing electric heating cables and are inconvenient to adjust the angle during testing.

[0005] To achieve the above objectives, the present invention provides a device for testing the bending performance of electric heating cables, comprising a worktable with two slide rails, and further comprising: two bending tables symmetrically arranged on the slide rails, a fixing member disposed within each bending table, a limiting post slidably connected to each bending table, a bending groove formed on each bending table, the limiting post slidably connected within the groove, a second sliding plate fixedly connected to the outer wall of the fixing member, the limiting post slidably connected to the second sliding plate, a first sliding plate fixedly connected to the outer wall of the limiting post, the fixing member slidably connected to the first sliding plate, and the first sliding plate and the second sliding plate being in contact; and further comprising:

[0006] The two drive mechanisms are respectively located at the positions of the corresponding fixed parts under the bending table, and are used to drive the fixed parts to rotate;

[0007] A moving mechanism is disposed between two slide rails, and two driving mechanisms are symmetrically disposed on the moving mechanism to drive the two bending tables to move away from or closer to each other.

[0008] The fixing component includes baffles, and two baffles are symmetrically arranged at the top of the fixing component to assist in fixing the electric heating cable.

[0009] Furthermore, the driving mechanism includes a movable block, which is threadedly connected to a slide rail. A drive motor is installed inside the movable block, and a drive gear is fixedly connected to the output end of the drive motor. A transmission gear is meshed with the inner wall of the drive gear, and a rotating shaft is fixedly connected to the lower surface of the transmission gear. The rotating shaft is rotatably connected to the inner wall of the movable block, and the upper surface of the transmission gear is fixedly connected to the bottom end of the fixing member.

[0010] Furthermore, the moving mechanism includes a fixed plate, two fixed plates are fixedly connected to the upper surface of the worktable, a servo motor is fixedly connected to one side of one of the fixed plates, a bidirectional lead screw is fixedly connected to the output end of the servo motor, the two ends of the bidirectional lead screw are respectively rotatably connected to the inner wall of the fixed plate, and the two driving mechanisms are threadedly connected to the bidirectional lead screw.

[0011] Furthermore, the fixing component also includes a sleeve, the bottom of which is fixedly connected to the upper surface of the transmission gear. A first tension spring is provided at the bottom of the sleeve, and a top-opening sleeve is slidably connected to the inner wall of the sleeve. A hollow circular plate is fixedly connected to the top of the sleeve, and a second tension spring is provided inside the hollow circular plate, penetrating both sides of the hollow circular plate. The other end of the first tension spring is located at the center of the second tension spring.

[0012] Furthermore, two baffles are symmetrically arranged on the outer wall of the hollow circular plate. The two baffles are respectively fixedly connected to the two ends of the second tension spring. A groove is provided on the hollow circular plate corresponding to the position of the baffle for the baffle to flip.

[0013] Furthermore, the limiting post includes a connecting post, which is slidably connected in a groove on the bending table. A limiting plate is fixedly connected to the lower surface of the connecting post, and the limiting plate is attached to the lower surface of the bending table. A cylinder is fixedly connected to the upper surface of the connecting post.

[0014] Furthermore, each of the slide rails is provided with at least four sets of sliders, and every two sets of sliders are fixedly connected to a support plate on one side of the bending table.

[0015] Furthermore, the first sliding plate and the second sliding plate are identical in shape, and each of the first sliding plate and the second sliding plate is provided with a fixing hole and a sliding groove. The fixing hole on the second sliding plate matches the sleeve, and the fixing hole on the first sliding plate matches the connecting column.

[0016] Furthermore, the inner surface of the baffle and the outer wall of the sleeve are both covered with anti-slip material.

[0017] The beneficial effects of this invention are as follows: As can be seen from the above description, the electric heating cable bending performance testing device provided by this invention, by pulling the hollow circular plate, causes the first tension spring to stretch and drive the two ends of the second tension spring to move inward. After the electric heating cable is placed, the hollow circular plate is lowered to move the sleeve downward, achieving the effect of adapting to electric heating cables of different sizes. At the same time, when the second tension spring retracts, the baffle can return to its initial position, thereby further fixing the electric heating cable from the side and preventing the heating cable from falling off during bending. Then, the driving mechanism drives the fixing component to rotate, which in turn drives the electric heating cable between the limiting columns to bend, thereby automatically adjusting the bending degree of the electric heating cable, improving accuracy. The performance of the electric heating cable can be observed by repeatedly bending the electric heating cable by rotating the driving mechanism. At the same time, the servo motor can be started to drive the bidirectional lead screw to rotate, causing the bending table to move away from or closer to each other, further changing the bending angle and bending radius of the electric heating cable. At this time, power is applied again to observe the performance of the electric heating cable under different bending degrees. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, an electric heating cable bending performance testing device includes a worktable 1 with two slide rails 2. It also includes two bending tables 3 symmetrically arranged on the slide rails 2, each bending table 3 containing a fixing member 6. A limiting post 7 is slidably connected to each bending table 3. A bending groove is formed on each bending table 3, and the limiting post 7 is slidably connected within the groove. A second sliding plate 9 is fixedly connected to the outer wall of the fixing member 6, and the limiting post 7 is slidably connected to the second sliding plate 9. A first sliding plate 8 is fixedly connected to the outer wall of the limiting post 7, and the fixing member 6 is slidably connected to the first sliding plate 8. The first sliding plate 8 and the second sliding plate 9 are in contact. The device further includes:

[0033] Two drive mechanisms 5 are respectively set at the positions of the corresponding fixed parts 6 under the bending table 3, and are used to drive the fixed parts 6 to rotate.

[0034] The moving mechanism 4 is located between the two slide rails 2, and two drive mechanisms 5 are symmetrically arranged on the moving mechanism 4 to drive the two bending tables 3 to move away from or closer to each other.

[0035] The fixing component 6 includes baffles 606, with two baffles 606 symmetrically arranged at the top of the fixing component 6 to assist in fixing the electric heating cable.

[0036] In this embodiment, when testing the bendability of the electric heating cable, the hollow circular plate 604 is first manually pulled upwards by the operator. Pulling the hollow circular plate 604 upwards stretches the first tension spring 602, which in turn applies a downward force to the second tension spring 605. This causes the two ends of the second tension spring 605 to move inwards, causing the baffles 606 at both ends to flip upwards, thus separating the baffles 606 from the outer wall of the hollow circular plate 604. At this point, the electric heating cable to be tested is passed through the fixing member 6 and the limiting post 7. The sleeve 603 is wrapped around the outer wall of the sleeve 601. Then the hollow circular plate 604 is released, causing the first tension spring 602 to retract and drive the sleeve 603 to move downward. When the lower end of the hollow circular plate 604 contacts the side wall of the electric heating cable, the force of the first tension spring 602 fixes the electric heating cable between the second sliding plate 9 and the hollow circular plate 604. At the same time as the sleeve 603 retracts, the force applied to the second tension spring 605 also decreases, so that the baffle 606 can return to the initial position to further fix the electric heating cable from the side, preventing the heating cable from falling off when bending.

[0037] After the electric heating cable is fixed to the outer wall of the two sleeves 601, the drive motor 502 is started to drive the drive gear 503 to rotate. When the drive gear 503 rotates, it can drive the transmission gear 504 to rotate, which in turn drives the fixing member 6 to rotate. When both fixing members 6 rotate, the fixing member 6 can drive the limiting post 7 to move along the slide groove opened on the bending table 3 through the first sliding plate 8 and the second sliding plate 9. When the limiting post 7 moves, the electric heating cable between the fixing member 6 and the limiting post 7 can be bent. Thus, the numerical performance of the electric heating cable can be observed through the tester. The bending angle of the electric heating cable can be adjusted by driving the fixing member 6 to rotate through the drive mechanism 5. The electric heating cable can be repeatedly bent to observe its performance.

[0038] Then, the servo motor 402 can be started to drive the bidirectional lead screw 403 to rotate. When the bidirectional lead screw 403 rotates, it can drive the two drive mechanisms 5 to move away from or closer to each other. Then, the bending table 3 can be moved by the fixing part 6 to change the distance between the two sets of bending tables 3. When the distance between the two bending tables 3 is different, the degree of bending of the electric heat tracing cable will also change. At this time, power is applied to observe the performance of the electric heat tracing cable under different degrees of bending.

[0039] When the electric heating cable passes between the fixing member 6 and the limiting post 7 and then bends, the outer wall of the cylinder 702 can always fit against the outer side of the electric heating cable to prevent the electric heating cable from falling off during the bending process.

[0040] Preferably, the drive mechanism 5 includes a movable block 501, which is threadedly connected to the slide rail 2. A drive motor 502 is installed inside the movable block 501. A drive gear 503 is fixedly connected to the output end of the drive motor 502. A transmission gear 504 is meshed with the inner wall of the drive gear 503. A rotating shaft is fixedly connected to the lower surface of the transmission gear 504. The rotating shaft is rotatably connected to the inner wall of the movable block 501. The upper surface of the transmission gear 504 is fixedly connected to the bottom end of the fixing member 6.

[0041] In use, after the electric heating cable is set up, the drive motor 502 drives the drive gear 503 to rotate. When the drive gear 503 rotates, it drives the transmission gear 504 that meshes with it to rotate. The rotation of the transmission gear 504 drives the fixing part 6 with the electric heating cable to rotate. When the fixing part 6 rotates, it drives the second sliding plate 9 to rotate as well. When the second sliding plate 9 rotates, it drives the limit post 7 to move along the slide groove on the bending table 3, thereby causing the electric heating cable to bend. By rotating the drive motor 502 in both directions, the fixing part 6 can be driven to perform a reciprocating rotation action, thereby pulling the electric heating cable to perform regular reciprocating bending. At the same time, by precisely controlling the rotation angle of the drive gear 503 adjuster, the rotation amplitude of the fixing part 6 can be finely adjusted, thereby achieving flexible adjustment of different bending degrees of the electric heating cable.

[0042] Preferably, the moving mechanism 4 includes a fixed plate 401, two fixed plates 401 are fixedly connected to the upper surface of the worktable 1, a servo motor 402 is fixedly connected to one side of one of the fixed plates 401, a bidirectional lead screw 403 is fixedly connected to the output end of the servo motor 402, the two ends of the bidirectional lead screw 403 are respectively rotatably connected to the inner wall of the fixed plate 401, and two driving mechanisms 5 are threadedly connected to the bidirectional lead screw 403.

[0043] When further adjustment of the bending angle and bending length of the electric heating cable is required during use, the servo motor 402 can be started to drive the bidirectional lead screw 403 to rotate. The bidirectional lead screw 403 is provided with threads in opposite directions at both ends, and each of the two threads corresponds to a drive mechanism 5. When the bidirectional lead screw 403 rotates, it can drive the two drive mechanisms 5 to move closer or further apart, thereby moving the two bending tables 3. After moving the bending tables 3 to the appropriate position according to the required adjustment angle, the drive mechanism 5 is started to drive the fixing part 6 and the limit post 7 to rotate, thereby adjusting the bending angle of the electric heating cable.

[0044] Preferably, the fixing member 6 further includes a sleeve 601, the bottom of which is fixedly connected to the upper surface of the transmission gear 504. A first tension spring 602 is provided at the bottom of the sleeve 601. A top-opening sleeve 603 is slidably connected to the inner wall of the sleeve 601. A hollow circular plate 604 is fixedly connected to the top of the sleeve 603. A second tension spring 605 is provided inside the hollow circular plate 604, penetrating both sides of the hollow circular plate 604. The other end of the first tension spring 602 is located at the center of the second tension spring 605. Two baffles 606 are symmetrically provided on the outer wall of the hollow circular plate 604. The two baffles 606 are respectively fixedly connected to the two ends of the second tension spring 605. A groove is provided on the hollow circular plate 604 corresponding to the position of the baffle 606 for the baffle 606 to flip.

[0045] In use, the electric heating cable needs to be fixed in place. The hollow circular plate 604 is manually pulled upwards. Pulling the hollow circular plate 604 stretches the first tension spring 602, which in turn exerts a downward force on the second tension spring 605. This causes the two ends of the second tension spring 605 to move inwards. During this movement, the baffles 606 at both ends flip upwards, causing them to separate from the outer wall of the hollow circular plate 604. At this point, the electric heating cable to be tested is passed between the fixing member 6 and the limiting post 7. The sleeve 603 is wound around the outer wall of the sleeve 601, and then the hollow circular plate 604 is released, causing the first tension spring 602 to retract and drive the sleeve 603 to move downward. When the lower end of the hollow circular plate 604 contacts the side wall of the electric heating cable, the electric heating cable is fixed between the second sliding plate 9 and the hollow circular plate 604 by the force of the first tension spring 602. At the same time as the sleeve 603 retracts, the force applied to the second tension spring 605 also decreases, so that the baffle 606 can return to the initial position to further fix the electric heating cable from the side.

[0046] When the second tension spring 605 drives the baffles 606 on both sides to flip, the position of the baffles 606 will change. A groove is provided on the hollow circular plate 604 at the position corresponding to the baffles 606, so that the baffles 606 will not be stuck when rotating, giving the baffles 606 enough rotation space.

[0047] Preferably, the limiting post 7 includes a connecting post 701, which is slidably connected in a groove on the bending table 3. A limiting plate 703 is fixedly connected to the lower surface of the connecting post 701, and the limiting plate 703 is attached to the lower surface of the bending table 3. A cylinder 702 is fixedly connected to the upper surface of the connecting post 701.

[0048] In use, when the fixing member 6 rotates, the limiting post 7 can be driven to slide in the groove of the bending table 3 via the second sliding plate 9. When the limiting post 7 slides, the first sliding plate 8 is fixed to the outer wall of the connecting post 701. The distance between the first sliding plate 8 and the limiting plate 703 is the same as the thickness of the bending table 3, and the diameter of the limiting plate 703 is greater than the width of the groove, so that the limiting post 7 will not fall off the bending table 3 when sliding. A cylinder 702 is fixed on the upper surface of the connecting post 701. When the fixing member 6 drives the electric heating cable to rotate, the cylinder 702 can always be in contact with the electric heating cable on the fixing member 6 to prevent the electric heating cable from slipping off when bending.

[0049] Preferably, each slide rail 2 is provided with at least four sets of sliders 201, and every two sets of sliders 201 are fixedly connected to a support plate on one side of the bending table 3.

[0050] In use, each bending table 3 has four sliders 201 fixed below it. When the bidirectional lead screw 403 rotates and drives the two bending tables 3 to move closer or further apart through the drive mechanism 5, the bending tables 3 can slide on the slide rail 2 through the sliders 201, making the sliding of the bending tables 3 smoother.

[0051] Preferably, the first sliding plate 8 and the second sliding plate 9 are identical in shape. Both the first sliding plate 8 and the second sliding plate 9 are provided with a fixing hole and a sliding groove. The fixing hole on the second sliding plate 9 matches the sleeve 601, and the fixing hole on the first sliding plate 8 matches the connecting post 701.

[0052] In use, the fixing holes and grooves on the first sliding plate 8 and the second sliding plate 9 are in the same position and size. The first sliding plate 8 and the second sliding plate 9 overlap vertically. The first sliding plate 8 is positioned below the second sliding plate 9 after the second sliding plate 9 has been rotated 180 degrees. The second sliding plate 9 is fixed to the fixing member 6, and the first sliding plate 8 is fixed to the limiting post 7. When the fixing member 6 rotates and drives the limiting post 7 to move, the limiting post 7 slides in the groove provided on the second sliding plate 9. At the same time, the limiting post 7 drives the first sliding plate 8 to move, so that the fixing member 6 slides in the groove of the first sliding plate 8. This not only allows the limiting post 7 to rotate synchronously when the fixing member 6 rotates, but also prevents the fixing member 6 and the limiting post 7 from slipping off during rotation. In addition, the groove also provides a moving distance for the limiting post 7 to move along the cauliflower on the bending table 3.

[0053] Preferably, the inner surface of the baffle 606 and the outer wall of the sleeve 601 are both covered with anti-slip material.

[0054] During use, the inner side of the baffle 606 and the outer wall of the sleeve 601 are the places that come into contact with the electric heating cable. Covering these two positions with anti-slip material can increase the friction between the baffle 606 and the sleeve 601 and the electric heating cable, further preventing the electric heating cable from falling off during bending tests.

[0055] This invention provides a device for testing the bending performance of electric heating cables. The electric heating cable to be tested is wrapped around the outer wall of a fixing member 6. Pulling the hollow circular plate 604 upwards stretches the first tension spring 602. When the first tension spring 602 is pulled, it causes the two ends of the second tension spring 605 to move inwards, thereby causing the baffles 606 at both ends to flip upwards. At this point, the electric heating cable to be tested can be passed between the fixing member 6 and the limiting post 7 and wrapped around the outer wall of the sleeve 601. Simultaneously, the second tension spring 605 retracts, allowing the baffles 606 to return to their initial position, further securing the electric heating cable from the side and preventing it from falling off during bending. Then, the drive motor 502 drives the drive gear 503 to rotate, which in turn drives the transmission gear 504 to rotate, thereby moving the fixing member... When both fixing parts 6 rotate, the limiting post 7 can move along the groove opened on the bending table 3. When the limiting post 7 moves, the electric heating cable between the fixing part 6 and the limiting post 7 can be bent, so that the numerical performance of the electric heating cable can be observed by the tester. The bending angle of the electric heating cable can be adjusted by driving the fixing part 6 to rotate through the drive mechanism 5, and the electric heating cable can be repeatedly bent to observe the performance of the electric heating cable. At the same time, the servo motor 402 can be started to drive the bidirectional lead screw 403 to rotate, and then the two bending tables 3 can be moved away from or closer to each other through the drive mechanism 5, changing the distance between the two sets of bending tables 3. When the distance between the two bending tables 3 is different, the bending degree of the electric heating cable will also change accordingly. At this time, power is applied to observe the performance of the electric heating cable under different bending degrees.
