Description

Technical Field

[0001] This utility model relates to insulating boards in the field of electrical equipment, and in particular to a combined insulating board adhesion testing device. Background Technology

[0002] Insulating boards are important insulating materials in power systems, and their adhesion to the substrate is a key indicator of construction quality and operational reliability. The insulation board adhesion test is used to determine the bond strength between the insulating material and the metallic conductor. By applying a tensile force to the sample at a controlled speed, the maximum tensile force at which the sample separates is recorded as the material's adhesion force.

[0003] Currently, two traditional methods are commonly used for adhesion testing of insulating boards: one is to place or suspend a single-weight counterweight directly at the test point, and the other is to use adhesive to fix the test fixture to the surface of the insulating board.

[0004] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems: First, the weight of a single counterweight is not adjustable, making it difficult to flexibly adapt to the different adhesion test values ​​required by insulation boards of different thicknesses and processes. If the weight needs to be changed, the entire counterweight needs to be replaced, which is cumbersome and requires the preparation of counterweights of various specifications, making it inconvenient to carry.

[0005] Secondly, adhesive fixing methods are prone to leaving adhesive residue on the surface of the insulation board after testing. In some cases, the excessive adhesive force may even damage the coating or structure of the insulation board itself, causing damage to the surface of the specimen and requiring rework and repair, which increases construction costs and time.

[0006] Therefore, there is an urgent need for an adhesion testing device that can be freely combined and fixed without damage. Summary of the Invention

[0007] To overcome the shortcomings of existing technologies and address the problems of inflexible adjustment of counterweights and damage to the surface of insulation board specimens in traditional insulation board adhesion tests, this application provides a combined insulation board adhesion testing device. This device uses a vacuum adsorption unit to adhere the counterweight to the surface of the insulation board, and a snap-fit ​​threaded connection enables rapid assembly of the counterweight modules, thus solving the technical problems in insulation board adhesion testing.

[0008] The solution adopted by the embodiments of this application to solve the technical problem is: A combined insulating board adhesion testing device includes a vacuum adsorption unit, a connecting mechanism, and a counterweight module; The vacuum adsorption unit is used to fix the entire device to the surface of the insulating board, and it includes a suction cup, a vacuum pump and connecting pipes. The vacuum pump is connected to the suction cup via a connecting pipe. By drawing a vacuum, a negative pressure is formed in the contact area between the suction cup and the insulating plate. The vacuum adsorption unit is then adsorbed onto the surface of the insulating plate by utilizing the difference between atmospheric pressure and negative pressure.

[0009] The connecting mechanism is located between the vacuum adsorption unit and the counterweight module, serving as a crucial link between the two. This connecting mechanism employs a hollow aluminum alloy structure design, effectively reducing the weight of the device. Its upper part is fixedly connected to the connecting pipe of the vacuum adsorption unit via a locking block, while its lower part features a ring for connecting the counterweight module.

[0010] The counterweight module adopts a split design to provide an adjustable test load; it includes a shackle and a counterweight unit; the upper end of the shackle is connected to the ring at the lower part of the connecting mechanism. The counterweight unit is an independent unit, including a basic counterweight unit with a weight of 0.25kg. Different total counterweight weights are formed by combining different numbers of counterweight units. Multiple counterweight units are connected and combined sequentially by snap-fit ​​threaded connection to achieve various weight specifications such as 0.25kg (single basic unit), 0.5kg (two-unit combination), and 1kg (four-unit combination). Anti-slip silicone pads are also provided on the contact surfaces between each counterweight unit to increase friction and prevent the assembly from sliding or loosening.

[0011] Positive effects: 1. Non-destructive fixing: Vacuum adsorption is used for fixing, which completely avoids the pollution and damage to the surface of the insulation board caused by adhesive bonding. There is no residue after testing, protecting the surface of the installed insulation board and avoiding rework and repair.

[0012] 2. Flexible and adjustable counterweight: The counterweight module adopts a modular split design, which can be quickly and flexibly combined into various weight specifications through snap-fit ​​threaded connection. It can accurately match the adhesion test requirements of insulation boards of different thicknesses and has strong versatility.

[0013] 3. Lightweight and easy to use: The device is made of lightweight materials and has a compact design. It is lightweight and small in size, making it easy for operators to carry to various on-site work locations and reducing the labor load of construction workers.

[0014] 4. Reliable connection: Anti-slip silicone pads are installed between the counterweight units, and they are connected by snap-fit ​​threads to ensure the stability and safety of the counterweight assembly and prevent accidental detachment during testing.

[0015] In summary, it is suitable for use as a combined insulation board adhesion testing device. Attached Figure Description

[0024] The counterweight module 3 adopts a split and modular design, including a shackle 9 and a counterweight unit 10; the upper end of the shackle 9 is connected to the ring 8 at the lower part of the connecting mechanism 2.

[0025] The counterweight unit 10 is an independent unit, including a basic counterweight unit with a weight of 0.25 kg.

Anti-slip silicone pads 11 are also provided on the contact surfaces between each counterweight unit 10 to increase friction and prevent the assembly from sliding or loosening.

[0026] The working process of this embodiment: In this embodiment, the following steps are followed when conducting the adhesion test on the insulating board: Step 1, Preparation: The device assembly was transported to the test site. First, the suction cup 4 of the vacuum adsorption unit 1 was placed and pressed onto the area to be tested on the insulating board, ensuring a flat and seamless contact surface. Then, the connecting pipe 5 was connected to the suction cup 4, and the vacuum pump 6 was connected to the connecting pipe 5.

[0027] Step 2, vacuum adsorption: After verifying that all pipe connections are correct, start the vacuum pump 6 to evacuate the suction cup 4. This creates a negative pressure between the suction cup 4 and the surface of the insulating board. Under atmospheric pressure, the vacuum adsorption unit 1 is firmly adsorbed onto the surface of the insulating board. Once the adsorption is confirmed to be secure, use the locking block 7 to lock and seal the connecting pipe 5. Then disconnect and remove the vacuum pump 6.

[0028] Step 3, Install the connecting mechanism: The upper end of the connecting mechanism 2 is connected and locked to the fixed connecting pipe 5 via its own locking block 7.

[0029] Step 4: Assemble and install the counterweight: Calculate and select the required counterweight weight based on the adhesion value required for the test. First, connect the upper end of the shackle 9 to the lower ring 8 of the connecting mechanism 2. Then, select the appropriate number of counterweight units 10 (such as combinations of 0.25kg, 0.5kg, or 1kg) and assemble them one by one using a snap-fit ​​threaded connection. Place anti-slip silicone pads 11 on the contact surfaces between each counterweight unit 10 to prevent slippage and detachment. Finally, connect the assembled counterweight module 3 to the uppermost counterweight unit 10 via the lower end of the shackle 9.

[0030] Step 5, Testing and Disassembly: After the counterweight module 3 is installed, start the timer and conduct an adhesion test for the specified time. After the test, disassemble the components in the reverse order of installation.
