Description

Technical Field

[0001] The present invention relates to the technical field of adhesion detection devices, and in particular to a coating adhesion detection device for power transmission and transformation equipment. Background Art

[0002] The transmission of electric current often results in losses due to heat generation in the wiring. Therefore, during transmission, the voltage is increased through transformers, reducing the current and minimizing heat loss. High voltage electricity is highly dangerous, and the target electrical equipment does not require such high voltage, so transformers are needed to reduce the voltage. Because current transmission requires multiple transformers, the process of current transmission is called transmission and transformation.

[0003] However, the existing coating adhesion detection device for power transmission and transformation equipment is relatively cumbersome in the bending process of the detection sample, the bending operation of the detection sample is poor, and the detection sample cannot be folded inward and outward, which reduces the accuracy of the coating adhesion detection of the power transmission and transformation equipment and has poor practicality.

The support plate and the rotating plate are both provided with a slide groove, and each of the slide grooves is provided with a fixed structure, and the fixing structure includes a fixing plate, and a limiting structure is provided on the support frame. The limiting structure includes a limiting frame, and a limiting rod is fixedly installed in the support frame, and the inner wall surfaces of both sides of the pusher are provided with an arc groove 1, and the two limiting rods respectively movably pass through the two arc grooves 1, and the two end portions of the pusher are fixedly mounted with a reinforcing plate for supporting the rack, and pulleys are rotatably mounted on both sides of the bottom end of the pusher.

[0006] As a preferred technical solution of the present invention, the surfaces of the two pulleys are in contact with the bottom surface of the inner wall of the support frame, and the two side ends of the rotating plate are fixedly installed with limit blocks. There are two limit frames, and the two limit frames are fixedly installed on the support frame.

[0007] As a preferred technical solution of the present invention, the two limit frames are respectively located on both sides of the rotating plate, the surfaces of the two limit frames are provided with arc groove 2, and the two limit blocks are respectively movable through the arc groove 2.

[0008] As a preferred technical solution of the present invention, arc rods are fixedly installed in the two arc grooves 2, the two arc rods are both arc-shaped, and two springs 2 are movably sleeved on the two arc rods.

[0009] As a preferred technical solution of the present invention, the two arc-shaped rods are movable through the two limit blocks respectively, and the two limit blocks are fixedly connected to the inner wall surfaces on both sides of the arc-shaped groove second through two springs second.

[0010] A movable baffle is movably mounted on the support plate, a fixed baffle is fixedly mounted on the rotating plate, a round block is fixedly mounted on the movable baffle, and a fixed rod is movably inserted into the round block.

[0011] The fixing rod is L-shaped and is fixedly mounted on the support frame. A circular plate is fixedly mounted on the fixing rod. A spring 1 is movably sleeved on the fixing rod. The circular plate is fixedly connected to the round block through the spring 1.

[0012] A threaded rod 2 is rotatably installed in each of the slide grooves, and a handwheel is fixedly installed at the end of each of the threaded rods 2. There are two groups of fixed plates, and each group of fixed plates is movably inserted in the slide grooves. There are two fixed plates in each group, and each fixed plate is L-shaped. Opposite threaded holes are opened on the surface of each two fixed plates, and each of the threaded rods 2 passes through two threaded holes.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, the rotation of the threaded rod will drive the pusher to move in the support frame, and the movement of the pusher will drive the two racks to move, and the movement of the two racks will drive the gears to rotate, and the rotation of the gears will drive the rotating plate to rotate with the rotating rod as the rotating axis. Since the position of the support plate is fixed, the rotation of the rotating plate will drive the test sample to rotate, and the test sample is bent. After the bending is completed, the adhesion of the coating on the power transmission and transformation equipment can be detected by observing whether the coating on the surface of the sample is peeled off. The reasonable structural design facilitates the adhesion detection of the coating on the power transmission and transformation equipment, and the operation is more convenient.

[0015] Secondly, by providing a fixed structure, the fixed plate is L-shaped, and by rotating the threaded rod 2, the two fixed plates are moved closer to or away from each other, which is convenient for fixing and disassembling the test sample, thereby facilitating the bending of the test sample. The fixed baffle is fixedly installed on the rotating plate, and the movable baffle is movably installed on the support plate. The movable baffle is moved to compress the spring 1, so that the gap between the movable baffle and the fixed baffle is adjustable, which makes it more convenient to fix and disassemble the test sample and more convenient to use.

[0016] Thirdly, the rotation of the rotating plate will drive the two limit blocks to slide in the arc groove 2 respectively. An arc rod is fixedly installed in the arc groove 2, and the arc rod movably passes through the limit block. The limit block is fixedly connected to the inner wall surfaces on both sides of the arc groove 2 through two springs 2, which plays a limiting and supporting role on the limit block, making the rotation of the rotating plate more stable, making the bending operation of the test sample more stable, and ensuring the stable operation of the detection device.

[0017] Fourthly, two limit rods are movable through the arc groove 1 respectively, which limit the pushing member, making the movement of the pushing member more stable, thereby making the movement of the two reinforcement plates more stable, ensuring the stable engagement of the reinforcement plates and the gears, and ensuring the stable operation of the drive structure. The surfaces of the two pulleys are in contact with the bottom surface of the inner wall of the support frame, which supports the pushing member, and the pulleys and the support frame have rolling friction, which reduces the friction between the pushing member and the support frame, making the movement of the pushing member smoother, and making the bending operation of the test sample smoother.

[0018] Fifth, the rotation of the threaded rod drives the pushing member to move, which can cause the gear to rotate clockwise or counterclockwise, thereby causing the rotating plate to rotate clockwise or counterclockwise, and can fold the test sample inward and outward. The pushing member is moved by the control of the threaded rod, and the rotation of the rotating plate is controlled by the movement of the pushing member, which can lock the angle of the sample after bending, thereby making the coating adhesion detection of the power transmission and transformation equipment more accurate, and improving the practicality of the coating adhesion detection device for power transmission and transformation equipment.
