Abstract
Description
Technical Field
[0001] This utility model relates to the field of power supply experimental equipment technology, specifically to an insulating rod withstand voltage test platform that is easy to position. Background Technology
[0002] The main function of the insulating rod withstand voltage test platform is to test the insulation performance of the insulating rod under high voltage, ensuring that it will not break down or leak electricity in actual use. This test effectively identifies defects, aging, or damage to the insulation material, thereby improving the safety of the insulating rod. The insulating rod withstand voltage test platform creates a voltage multiplication effect by applying test voltages of opposite polarity, resulting in a voltage to ground voltage of only 50% of the rated test voltage, significantly reducing the voltage to ground and thus reducing the height requirement of the test platform.
[0003] However, traditional insulating rod withstand voltage test platforms have the following drawbacks:
[0004] Traditional insulating rod withstand voltage test platforms use clamps to hold and fix the insulating rod from both sides to complete the withstand voltage test. Traditional clamps can only hold the insulating rod from both sides in one direction. Under the impact of external force, the insulating rod may shift from the other side, requiring the insulating rod to be re-fixed, which reduces the testing efficiency of the insulating rod. Utility Model Content
[0005] The purpose of this invention is to provide an easy-to-position insulating rod withstand voltage test platform to solve the problem mentioned in the background art that the traditional insulating rod withstand voltage test platform completes the withstand voltage test by clamping and fixing the insulating rod from both sides with clamps. The traditional clamps can only clamp the insulating rod from both sides in one direction. Under the impact of external force, the insulating rod may shift from the other side, requiring the insulating rod to be re-fixed, which reduces the testing efficiency of the insulating rod.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an insulating rod withstand voltage test platform for easy positioning, comprising a fixed base, height plates fixedly installed on both sides of the top of the fixed base, a top plate provided at the top of the fixed base, a lead screw rotatably connected between the tops of the two top plates, a movable block slidably connected to the middle of the lead screw, a test component fixedly installed at the bottom of the movable block, and a fixing mechanism installed at the middle of the top of the fixed base, the fixing mechanism comprising a fixed housing and two length shells, a fixing groove provided at the top of the fixed housing, the interior of the fixing groove being rotatable. The test assembly includes a connecting rod with two displacement blocks that are slidably connected to a fixed groove on its surface. One side of the top of each displacement block is fixedly connected to the bottom of two length shells. The top of each length shell is slidably connected to a fixed frame, and the bottom of each fixed frame is provided with a pressure plate. The test assembly includes a first lifting platform and a voltage test head. A first lifting cylinder is fixedly installed at the bottom of the first lifting platform, and a second lifting platform is fixedly installed at the fixed end of the first lifting cylinder. A voltage test head is fixedly installed at the bottom of the second lifting platform, and a wire connector is fixedly installed at one end of the voltage test head.
[0007] Preferably, each of the two fixing frames is threaded with a length rod at its middle. The bottom ends of the two length rods are rotatably connected to the top ends of the two pressure plates, and silicone plates are fixedly installed at the bottom ends of the two pressure plates. Positioning platforms are fixedly installed on opposite sides of the two fixing frames. Assembly rods are rotatably connected to the middle of the two positioning platforms, and the bottom ends of the two assembly rods are threadedly connected to the top ends of the two displacement blocks. When the user rotates the length rod, the threads on the surface of the length rod match the threads on the inner wall of the fixing frame. The length rod pushes the pressure plate from the top to adjust the height of the pressure plate. The pressure plate and the fixing housing cooperate to clamp and fix the insulating rod. Then, the user rotates the assembly rod, and the threads on the surface of the assembly rod match the threads on the inner wall of the displacement block. The assembly rod rotates and rises relative to the displacement block, causing the fixing frame to slide relative to the length shell through the positioning platform, thus making a secondary adjustment to the position of the pressure plate.
[0008] Preferably, a servo motor for driving the connecting rod to rotate is fixedly installed on the surface of the fixed housing. After the servo motor is powered on, it starts and drives the connecting rod to rotate. The connecting rod has two threads in opposite directions with its own center line as the dividing line. The threads on the inner walls of the two displacement blocks match the threads on the surface of the connecting rod. The two displacement blocks are limited by the fixed grooves that match their shape and size. Therefore, the two displacement blocks slide relative to each other along the connecting rod to adjust the position of the two length shells.
[0009] Preferably, the bottom end of the fixed housing is fixedly connected to the fixed base, and the fixing mechanism is installed on the fixed base through the fixed housing.
[0010] Preferably, movable rods that are slidably connected to the first lifting platform are fixedly installed on both sides of the top of the second lifting platform. A second lifting cylinder is fixedly installed on the top of the first lifting platform. The fixed end of the second lifting cylinder is fixedly connected to the side of the movable block facing it. The first lifting cylinder performs a telescopic movement, pushing the second lifting platform from the top. The second lifting platform causes the movable rods to slide relative to the first lifting platform, adjusting the height of the voltage test head. The second lifting cylinder performs a telescopic movement, pushing the first lifting platform from one side to adjust the height of the voltage test head. The wire connection connector connects the voltage test head to the power supply for assembly.
[0011] Preferably, a lead screw for driving a stepper motor is fixedly installed on the surface of one of the height plates. The top ends of the two height plates are respectively fixedly connected to the two sides of the bottom end of the top plate. After the stepper motor is powered on, it starts and drives the lead screw to rotate. The thread on the surface of the lead screw matches the thread on the inner wall of the movable block. The movable block is limited by the top plate, which matches its shape and size. Therefore, the movable block slides along the lead screw to adjust the position of the test component.
[0012] Preferably, a support frame is fixedly installed at the bottom of the fixed base, and the support frame provides support from the bottom of the fixed base.
[0013] Compared with the prior art, the beneficial effects of this utility model are: by setting a fixing mechanism, the displacement block slides relative to the connecting rod, and the displacement block drives the length shell to move synchronously during the sliding process. The two length shells cooperate to clamp and fix the insulating rod from both sides. The pressure plate and the fixing housing clamp and fix the insulating rod from another direction, avoiding the phenomenon of position displacement of the insulating rod under the condition of external force collision, and improving the testing efficiency of the insulating rod.

The length rod 308 pushes the pressure plate 309 from the top to adjust the height of the pressure plate 309. The pressure plate 309 and the fixing housing 301 cooperate to clamp and fix the insulating rod. Then the user rotates the assembly rod 311. The threads on the surface of the assembly rod 311 are matched with the threads on the inner wall of the displacement block 303. The assembly rod 311 rotates and rises relative to the displacement block 303, so that the fixing frame 307 slides relative to the length housing 306 through the positioning table 312, and the position of the pressure plate 309 is adjusted a second time.
[0023] A servo motor 305 that drives the connecting rod 304 to rotate is fixedly mounted on the surface of the fixed housing 301. After the servo motor 305 is powered on, it starts and drives the connecting rod 304 to rotate.

The threads on the inner walls of the two displacement blocks 303 match the threads on the surface of the connecting rod 304. The two displacement blocks 303 are limited by the fixing grooves 302 that match their shape and size. Therefore, the two displacement blocks 303 slide relative to each other along the connecting rod 304, adjusting the position of the two length shells 306.

The threads on the inner walls of the two displacement blocks 303 match the threads on the surface of the connecting rod 304. The two displacement blocks 303 are limited by the fixing grooves 302 that match their shape and size, so the two displacement blocks 303 slide relative to each other along the connecting rod 304, adjusting the position of the two length shells 306. The user rotates the length rod 308, and the threads on the surface of the length rod 308 match the threads on the inner wall of the fixing frame 307.
