Description

Technical Field

[0001] This utility model belongs to the field of power engineering technology, and specifically relates to a testing and experimental device. Background Technology

[0002] In the field of power engineering, the performance testing of safety belts such as high-altitude work safety belts and substation protective belts is crucial. However, traditional tensile testing equipment can only test one belt at a time. Comparing different batches or specifications of belts requires repeated operations, resulting in a long testing cycle. This makes it difficult to meet the high-efficiency requirements of power maintenance. Furthermore, the fixed clamping distance and winding position of the equipment cannot adapt to the flexible requirements of the number and length of belts in power engineering. Testing multiple belts is prone to tangling and uneven tension, making it difficult to meet the needs of power field testing and batch quality inspection in workshops, thus limiting its widespread application. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a testing and experimental device to solve the problems mentioned above.

[0004] To achieve the above objectives, a testing device includes a tray with two symmetrical mounting seats slidably connected to its inner wall. A vertical rod is mounted on each mounting seat, and a sliding plate is slidably connected to one side of each vertical rod. Corresponding clamps are mounted on the sliding plate and the mounting seats. Clamping blocks are engaged with each clamp, and a slot is formed on one side of each clamping block. A horizontal bar is engaged with the inner wall of the slot. Two of the horizontal bars have connecting holes, and the other two connecting holes have mating grooves. A pressure rod A is threadedly connected to the inner wall of each connecting hole. A truss is positioned above the horizontal bar, and a sliding sleeve is slidably connected to the truss. A winding rod is positioned on the outer side of the sliding sleeve.

[0005] Preferably, a slide rod is installed on the inner wall of the tray, and the slide rod passes through the mounting base.

[0006] Preferably, an adjusting rod is rotatably connected to the inner wall of the upright, and a slider that is threadedly connected to the adjusting rod is installed on one side of the sliding plate.

[0007] Preferably, the connecting hole corresponds to the mating groove, and a friction pad is rotatably connected to one end of the crossbar and the pressure rod A.

[0008] Preferably, a mounting bracket is installed on one of the crossbars, and both ends of the truss are connected to one side of the mounting bracket.

[0009] Preferably, a pressure rod B is threaded onto the sliding sleeve, and one end of the pressure rod B is in contact with the top of the truss.

[0010] This utility model has the following beneficial effects: Tightening pressure rod A allows the friction pad to press tightly against the belt into the mating groove, preventing belt displacement during testing. Simultaneously, the sliding sleeve slides along the truss to adjust the position of the winding rod, which, in conjunction with pressure rod B, locks in place. This ensures low length deviation after multiple belts are wound up, with significantly better tension consistency than traditional equipment, reducing test data errors. Furthermore, the horizontal sliding adjustment of the mounting base via the sliding rod, along with the winding structure of the crossbar and winding rod, prevents belt entanglement and interference, making it particularly suitable for batch quality comparison testing scenarios.

[0013] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0014] Example 1: As Figure 1 As shown in Figure 4, this utility model provides the following technical solution: It includes a tray 1, with two symmetrical mounting seats 11 slidably connected to the inner wall of the tray 1. A vertical rod 12 is installed on the mounting seat 11, and a sliding plate 13 is slidably connected to one side of the vertical rod 12. Upper and lower corresponding clamps 2 are installed on the sliding plate 13 and the mounting seat 11. A locking block 21 is engaged with the clamp 2. A locking groove 22 is opened on one side of the locking block 21. A horizontal bar 23 is engaged with the inner wall of the locking groove 22. Two of the horizontal bars 23 have connecting holes 24, and the other two connecting holes 24 have mating grooves 25. A pressure rod A26 is threadedly connected to the inner wall of the connecting hole 24. A truss 31 is provided above the horizontal bar 23. A sliding sleeve 32 is slidably connected to the truss 31, and a winding rod 33 is provided on the outer side of the sliding sleeve 32.

[0015] In this implementation scheme: A pallet 1 serves as the basic load-bearing component of the equipment. Two symmetrical mounting seats 11 are slidably connected to its inner wall, providing installation support for the subsequent belt clamping and inspection structure. A vertical rod 12 is fixedly mounted on the mounting seat 11. A sliding plate 13 is slidably connected to one side of the vertical rod 12, and clamps 2 with corresponding upper and lower positions are mounted on the sliding plate 13 and the mounting seat 11, forming an upper and lower clamping assembly. A locking block 21 engages with the clamp 2. A slot 22 on one side of the locking block 21 engages with and fixes a horizontal bar 23. The lower horizontal bar 23 is used to directly clamp one end of the safety belt or other belt components, while the upper horizontal bar 23... For guiding the belt's direction, two crossbars 23 have connecting holes 24. Two other connecting holes 24 that contact the belt have mating grooves 25. A pressure rod A26 is threaded into the inner wall of the connecting holes 24. Tightening the pressure rod A26 further locks the belt, preventing loosening during testing. When the lower crossbars 23 perform tensile tests on various belts requiring safety testing, one end of each belt being tested can be simultaneously fixed between the lower crossbars 23, ensuring a uniform position for each belt end. A truss 31 is installed above the upper crossbars 23. A sliding sleeve 32 connected to the truss 31 corresponds to each belt initially installed. A winding rod is installed on the outside of the sliding sleeve 32. 33. The belt body passes through the upper crossbar 23, and the end of the belt body supported between the upper and lower crossbars 23 is wound up to the winding rod 33, so that multiple belt bodies to be tested are kept at the same length. The belt body part between the upper crossbars 23 is fixed by the pressure rod A26. The crossbar 23 slides on one side of the upright 12, and the displacement of the upper crossbar 23 is pulled. Finally, the quality inspection of multiple types of belt bodies is completed at the same time, so as to quickly detect and compare the quality differences of each belt body, thereby identifying the safety belt body with better quality. This can effectively ensure the safety of electrical work when working at height. At the same time, the distance between the two can be adjusted by the sliding mounting seat 11, which can be flexibly adapted according to the actual number of belt bodies to be tested.

[0016] A slide rod 111 is installed on the inner wall of the tray 1, and the slide rod 111 passes through the mounting seat 11. When the number of safety belts to be tested changes, the mounting seat 11 can be pushed to slide horizontally along the slide rod 111 to adjust the distance between the two mounting seats 11. After the distance is adjusted, it can be ensured that each belt can correspond to a set of upper and lower crossbars 23 and winding rods 33, avoiding the belts from tangling or uneven tension, and adapting to the synchronous testing requirements of different numbers of belts.

[0017] An adjusting rod 121 is rotatably connected to the inner wall of the upright 12, and a slider threadedly connected to the adjusting rod 121 is installed on one side of the slide plate 13; the adjusting rod 121 is rotatably connected to the inner wall of the upright 12 through a bearing, and a slider threadedly matched with the adjusting rod 121 is welded to one side of the slide plate 13. The slider is embedded in the slide groove of the inner wall of the upright 12 and can only slide up and down. When the adjusting rod 121 is rotated, the threaded transmission drives the slider to move up and down along the slide groove of the upright 12, thereby driving the slide plate 13 and the clamp 2 and crossbar 23 installed above it to rise and fall synchronously.

[0018] The connecting hole 24 corresponds to the mating groove 25. One end of the crossbar 23 and the pressure bar A26 is rotatably connected to a friction pad 27. The connecting hole 24 and the mating groove 25 are on the same vertical line. One end of the crossbar 23 and the pressure bar A26 are rotatably connected by a rotating shaft. The end of the pressure bar A26 is rotatably connected to a rubber friction pad 27. When clamping the belt, the pressure bar A26 is rotated to make the friction pad 27 press tightly against the surface of the belt into the mating groove 25. Then, the pressure bar A26 is continued to be turned to make it engage with the thread of the connecting hole 24 and lock it in place. The friction pad 27 can increase the friction with the belt, prevent the belt from shifting during winding and traction, ensure that the tension on each belt is consistent, and improve the accuracy of the test data.

[0019] One of the crossbars 23 is equipped with a mounting bracket 3, and the two ends of the truss 31 are connected to one side of the mounting bracket 3. The upper crossbar 23 near the middle of the equipment is selected, and the mounting bracket 3 is welded to its outer side. The two ends of the truss 31 are fixedly connected to one side of the mounting bracket 3 by bolts. The truss 31 is directly connected to the mounting bracket 3 corresponding to the crossbar 23. When the crossbar 23 rises and falls with the slide plate 13, the truss 31 can move synchronously, always maintaining a suitable winding height with the belt. At the same time, the truss 31 provides a sliding track for the sliding sleeve 32, ensuring that the winding rod 33 can only move along the belt arrangement direction, avoiding the belt from tilting during winding, and ensuring that multiple belts are wound and stressed synchronously.

[0020] A pressure rod B34 is threaded onto the sliding sleeve 32, with one end of the pressure rod B34 fitting against the top of the truss 31. The sliding sleeve 32 is fitted onto the outside of the truss 31, and a threaded hole is opened at the top of the sliding sleeve 32. The pressure rod B34 is threaded into the threaded hole, and the lower end of the pressure rod B34 can fit tightly against the top of the truss 31. According to the length of the belt to be tested, the sliding sleeve 32 moves along the truss 31, so that the winding rod 33 is in a position that matches the end of the belt. After the position is determined, the pressure rod B34 is tightened clockwise, and its lower end presses tightly against the top of the truss 31. The sliding sleeve 32 is locked by friction to prevent the winding rod 33 from shifting during the winding process, which would cause the belt length to be unequal, thus ensuring uniform tension conditions when multiple types of belts are tested simultaneously.

[0021] The working principle of this technical solution is as follows: Next, according to the number of belts, push the mounting seat 11 along the slide bar 111 to adjust the spacing, then rotate the adjusting rod 121 to adjust the height of the slide plate 13 to match the tension length of the belt, and slide the sliding sleeve 32 to position the winding rod 33 at the winding position. Then, insert one end of each belt into the slot 22 of the lower crossbar 23, and wrap the other end around the upper crossbar 23 and onto the winding rod 33 to complete the clamping of all belts. Then, turn the pressure rod A26 one by one to press the belt to the docking groove 25 through the friction pad 27. After fine-tuning the winding rod 33 to make the belt slightly tensioned, use the pressure rod B34 to lock the sliding sleeve 32 to achieve full fixation of the belt. Then, start the equipment to apply tension, record the belt breaking tension, elongation and other data for testing, and finally loosen all fixing parts pressure rod A26 and pressure rod B34 to take out the belt.
