Description

Technical Field

[0001] This utility model relates to the field of insulating tie rod clamping technology, specifically an insulating tie rod testing device. Background Technology

[0002] Electrical safety tools and equipment are indispensable protective equipment for power workers engaged in power installation, maintenance, emergency repair, upkeep, and inspection. Widely used in power systems, they are referred to in the industry as the "last line of defense" for the power grid. Therefore, ensuring the qualified quality of electrical safety tools and equipment and conducting regular preventative testing plays a crucial role in guaranteeing the safe operation of the power grid and the safety of personnel.

[0003] Insulated pull rods are insulating tools specifically designed for power systems, primarily used for live-line working, live-line inspection, and live-line maintenance. They consist of three parts: a working head, an insulating rod, and a handle. They can be used for closing or opening high-voltage disconnect switches, installing or removing portable grounding wires, and performing measurements and tests. The applications of insulated pull rods are wide-ranging, including but not limited to the opening and closing of high-voltage disconnect switches and drop-out fuses, the installation and removal of temporary grounding wires, discharge operations, and handling foreign objects on live conductors. Furthermore, they are used for high-voltage measurements, tests, and various operations involving direct contact with live conductors.

[0004] Insulating tie rods are designed with electrical operation safety in mind. Their materials and structure can withstand high-voltage environments while providing sufficient insulation protection to prevent current leakage or short circuits. These tools typically adhere to the DL 408-91 standard, ensuring their reliability and safety in various electrical operations. Regular inspection and maintenance of the insulating tie rods are also crucial to ensuring their performance; annual testing is generally required to ensure their insulation performance and mechanical strength meet standards.

[0005] In conclusion, insulating tie rods are not only important tools for performing various live operations in power systems, but also indispensable equipment for ensuring the safe operation of power systems.

[0006] However, existing insulating tie rod test fixtures cannot be adjusted according to the size of the insulating tie rod, making it inconvenient to perform clamping tests on insulating tie rods of different sizes, which is quite troublesome. Therefore, we propose an insulating tie rod test device to solve the above-mentioned problems. Utility Model Content

[0027] In one embodiment, such as Figures 1-3 As shown, an insulating tension rod testing device includes:

[0028] First clamping plate 1;

[0029] The second clamping plate 2 is located below the first clamping plate 1;

[0030] The connecting hole 3 is provided in two sets, respectively located on one side of the first clamping plate 1 and the second clamping plate 2;

[0031] The mounting holes 4 are provided in two sets, respectively located on the other side of the first clamping plate 1 and the second clamping plate 2;

[0032] A distance adjustment component is used to adjust the distance between the first clamping plate 1 and the second clamping plate 2, and is disposed on the first clamping plate 1 and the second clamping plate 2. The distance adjustment component is a screw-driven adjustment structure.

[0033] The distance adjustment assembly includes two sets of adjustment blocks 5, which are respectively disposed on one side wall of the first clamping plate 1 and the second clamping plate 2. Each set of adjustment blocks 5 is threaded with an adjustment screw 6. A rotating block 7 is disposed between the two sets of adjustment screws 6. A support plate 8 is disposed on the other end wall of the two sets of adjustment screws 6. A sliding frame 9 is disposed on one side inner wall of the support plate 8. Two sets of sliders 10 are slidably disposed on the inner wall of the sliding frame 9. The other ends of the two sets of sliders 10 are respectively disposed on the side wall of the two sets of adjustment blocks 5. Limiting slide rods 11 are slidably disposed on the two sets of sliders 10. The upper and lower ends of the limiting slide rods 11 are respectively disposed on the upper and lower inner walls of the sliding frame 9.

[0034] In this embodiment, when testing the insulating tie rod, the distance between the first clamping plate 1 and the second clamping plate 2 is adjusted according to the length of the insulating tie rod. During adjustment, the rotating block 7 is rotated, which drives the two sets of adjusting screws 6 to rotate. With the cooperation of the sliding frame 9, the slider 10, and the limiting slide rod 11, the two sets of adjusting screws 6 drive the two sets of adjusting blocks 5 to move, thereby moving the first clamping plate 1 and the second clamping plate 2, thus allowing the distance between the first clamping plate 1 and the second clamping plate 2 to be adjusted. By setting the distance adjustment component, it is convenient to adjust the distance between the first clamping plate 1 and the second clamping plate 2 according to the size of the insulating tie rod being tested. This allows the test distance to be adjusted arbitrarily according to the size of the insulating tie rod, which can accommodate different models of insulating tie rod test fixtures, improves the working efficiency of insulating tie rod testing, and is more practical and convenient.

[0035] like Figures 1-3 As shown, each of the two sets of mounting holes 4 has two sets of fixing members 12 inside. Each set of fixing members 12 has a set of pull rods 13 on its side wall. The other end of each set of pull rods 13 slides through the first clamping plate 1 and the second clamping plate 2, extending to the outside of the first clamping plate 1 and the second clamping plate 2. Each set of pull rods 13 has a set of circular blocks 14 on its outer wall. Each set of circular blocks 14 has a set of fastening springs 15 on one side wall. Each set of fastening springs 15 is sleeved on the outside of the pull rods 13. The other end of each set of fastening springs 15 has a set of fixing brackets 16. The set of fixing brackets 16 slides through the tie rods 13 and is respectively set on the side walls of the first clamping plate 1 and the second clamping plate 2; each of the other ends of the multiple sets of tie rods 13 is provided with a set of pulling blocks 17; after the distance between the first clamping plate 1 and the second clamping plate 2 is adjusted to a suitable position, the insulating tie rod is inserted into the two sets of mounting holes 4, so that the multiple sets of fixing parts 12 are fixedly clamped on the outside of the insulating tie rod under the tight pressure of the fastening spring 15, so that the insulating tie rod is fixed on the first clamping plate 1 and the second clamping plate 2, which can play a fixing role for the insulating tie rod and improve the working quality of the insulating tie rod test.

[0036] The above embodiment discloses an insulating tie rod testing device. When testing the insulating tie rod, the distance between the first clamping plate 1 and the second clamping plate 2 is adjusted according to the length of the insulating tie rod. During adjustment, the rotating block 7 is rotated, causing two sets of adjusting screws 6 to rotate. With the cooperation of the sliding frame 9, the slider 10, and the limiting slide rod 11, the two sets of adjusting screws 6 drive two sets of adjusting blocks 5 to move, causing the first clamping plate 1 and the second clamping plate 2 to move, thereby adjusting the distance between the first clamping plate 1 and the second clamping plate 2. After adjusting the distance between plate 1 and the second clamping plate 2 to a suitable position, the insulating tie rod is inserted into the two sets of mounting holes 4, so that multiple sets of fixing parts 12 are fixedly clamped on the outside of the insulating tie rod under the tight pressure of the fastening spring 15, so that the insulating tie rod is fixed on the first clamping plate 1 and the second clamping plate 2. Then, it is connected to the horizontal tensile testing machine through the two sets of connecting holes 3 to test the insulating tie rod. Thus, the test distance can be adjusted at will according to the size of the insulating tie rod, which can meet the test fixtures of different models of insulating tie rods and improve the working efficiency of insulating tie rod testing.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
