[0002] The "effective insulation length" of an insulating rod refers to the net length of the insulating material after removing the metal parts from the working part of the insulating rod. When testing an insulating rod, a clamping device is needed to limit the insulating rod sample. Chinese Patent No. CN207164097U discloses an insulating rod test bracket, comprising a fixed test bracket, a left-moving test bracket, and a right-moving test bracket. The fixed test bracket has a fixed test electrode frame at the top and a fixed base at the bottom. The left-moving test bracket has a left-moving test electrode frame at the top and a left-moving base at the bottom.

The left and right moving bases are connected to the fixed base via screw drives. A screw drive motor is installed inside the fixed base. The insulating rod is fixed to the electrode frame. Based on existing solutions and actual production and processing applications, the existing high-voltage insulation distance control clamping device is inconvenient for fixing insulation rod samples of different diameters in the clamping structure. Therefore, we propose a high-voltage insulation distance control clamping device to solve the problems mentioned above. Utility Model Content

A U-shaped frame is fixed to the outer end of the base plate, a hydraulic rod is fixed to the upper surface of the base plate, a top plate is fixed to the output end of the hydraulic rod, and a position adjustment structure is fixed inside the top plate; A first soft cotton block is installed below the position adjustment structure, and a second soft cotton block is installed in the top slot of the base plate.

[0005] Using the above technical solution, multiple groups of samples with the same diameter can be fixed simultaneously, and samples with different diameters can also be fixed, making it convenient to replace the soft cotton block.

[0006] Preferably, the U-shaped frame is symmetrically arranged about the center line of the base plate, and the top plate is located inside the U-shaped frame.

[0007] Preferably, the position adjustment structure includes a screw, a mounting plate, a limiting rod, and a flat plate.

A hydraulic rod is fixed to the upper surface of the base plate, and a top plate is fixed to the output end of the hydraulic rod. When the size of the multiple sets of insulating rod samples to be fixed is consistent, the first soft cotton blocks set at equal angles are at the same height. When the hydraulic rod is started, the hydraulic rod drives the top plate to rise and fall, which can synchronously drive the multiple sets of first soft cotton blocks to rise and fall, and quickly fix samples of the same diameter. 2. The top plate is internally fixed with a position adjustment structure, which includes a screw, a mounting plate, a limiting rod and a flat plate. The position adjustment structure can adjust the distance between the first and second soft cotton blocks in each group, thereby fixing samples of different diameters. 3.

A brake wheel 2 is fixed to the bottom of the base 1, and the base 1 moves with the help of the brake wheel 2. Support rods 3 are fixed to both the front and rear ends of the upper surface of the base 1. A base plate 4 is fixed to the top of the support rods 3. A U-shaped frame 5 is fixed to the outer end of the base plate 4. A hydraulic rod 6 is fixed to the upper surface of the base plate 4. A top plate 7 is fixed to the output end of the hydraulic rod 6. The U-shaped frame 5 is symmetrically arranged about the center line of the base plate 4, and the top plate 7 is located inside the U-shaped frame 5. A position adjustment structure is fixed inside the top plate 7. A first soft cotton block 12 is installed below the position adjustment structure, and a second soft cotton block 13 is installed in the top slot of the base plate 4; The first soft cotton block 12 and the second soft cotton block 13 are set in a one-to-one correspondence. The sample to be tested is placed between the first soft cotton block 12 and the second soft cotton block 13. Since the first soft cotton block 12 and the second soft cotton block 13 are set at equal angles, multiple sets of samples can be placed between the bottom plate 4 and the top plate 7. When the diameter of each set of insulating rods that need to be pressed is the same, the hydraulic rod 6 is activated by the controller. The hydraulic rod 6 drives the top plate 7 to move downward, so that the second soft cotton blocks 13 set at equal angles move downward together to fix the sample. The position adjustment structure includes a screw 8, a mounting plate 9, a limiting rod 10, and a flat plate 11. The screw 8 is threadedly connected to the inside of the top plate 7.

The limiting rod 10 passes through the inside of the top plate 7, and the screw 8 is installed on the top plate 7 at equal intervals. When the required sample diameters are inconsistent, after placing the sample on the second soft cotton block 13, the staff manually rotates each set of screws 8 clockwise, causing the mounting plate 9 and the limiting rod 10 to move downwards, thereby causing the flat plate 11 and the first soft cotton block 12 to move downwards, and using the first soft cotton block 12 and the second soft cotton block 13 to press the sample. The top of the first soft cotton block 12 is installed at the bottom of the flat plate 11 through a slot. The second soft cotton block 13 is connected to the bottom plate 4 by a slot connection. By pulling the first soft cotton block 12 and the second soft cotton block 13 outward, the first soft cotton block 12 and the second soft cotton block 13 can be removed and replaced.
