Description

Technical Field

[0001] The utility model relates to the technical field of clamps for transformer oil tank steel plates, in particular to a clamp for transformer oil tank steel plates. Background Art

[0002] The oil tank is the outer shell of the transformer, which is welded from steel plates to hold the transformer body (including the core and winding) and transformer oil. In order to enhance cooling, radiators are generally installed around the oil tank to expand the heat dissipation area of ​​the transformer. When using it, the steel plate needs to be clamped with a clamp, but traditional clamps are mostly manually operated, so the clamping force is either too large or too small, so that the steel plate is not clamped tightly enough, or too tight will damage the steel plate. In view of the above problems, a clamp for transformer oil tank steel plate with controllable clamping force is required. Utility Model Content

[0003] The purpose of the utility model is to provide a clamp for a transformer oil tank steel plate to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A clamp for transformer oil tank steel plate, comprising a base, a control button embedded in a longer side surface of the base, a battery installed on a longer side surface inside the base, a processor installed on the inner side of the base and at an end away from the battery, a first clamping plate installed at a narrow edge of the top of the base, a limiting plate installed on the top of the base and at an end away from the first clamping plate, a multi-layer telescopic rod installed on a longer side surface of the limiting plate, a second clamping plate installed on the outer side of the multi-layer telescopic rod and at an end away from the limiting plate, a pressure sensor installed on the outer side of the second clamping plate and at an end away from the multi-layer telescopic rod, a slider installed at the bottom of the second clamping plate, a cavity opened at the top of the base, a threaded rod installed inside the cavity, and a rotating motor installed at one end of the threaded rod.

[0006] As a preferred solution of the utility model, the second clamping plate is installed on the top of the base, wherein the second clamping plate is slidably connected to the top of the base.

[0007] As a preferred solution of the utility model, the sliding block extends into the cavity and is threadedly connected to the threaded rod.

[0008] As a preferred solution of the utility model, both ends of the threaded rod are rotatably connected to the inside of the cavity.

[0009] As a preferred solution of the utility model, one end of the threaded rod extends to the inside of the base to be connected to the rotating motor.

[0010] As a preferred solution of the utility model, the control button is electrically connected to the battery, the processor, the multi-layer telescopic rod, the pressure sensor, and the rotating motor through wires.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, a clamp for a transformer oil tank steel plate is set up, and a control button, a multi-layer telescopic rod, a second clamping plate, a pressure sensor, a slider, a cavity, a threaded rod, and a rotating motor are used to control the clamping force of the device. The clamping pressure value of the clamp is set by clicking the control button. After the setting is completed, the device is placed on the transformer oil tank steel plate. After the placement is completed, the start button on the control button is clicked to make the rotating motor run, drive the threaded rod to rotate, and make the slider move on the threaded rod, thereby driving the second clamping plate to move on the top of the base. At the same time, the multi-layer telescopic rod extends to push the second clamping plate to move, so that the second clamping plate is close to the steel plate until the pressure sensor contacts and squeezes the steel plate, so that the steel plate is clamped between the first clamping plate and the second clamping plate. The clamping pressure will be sensed by the pressure sensor until the clamping pressure reaches the set pressure value. The pressure sensor senses so that the rotating motor and the multi-layer telescopic rod stop running, thereby avoiding the situation that the clamping force is insufficient, the clamping is not tight, or the pressure is too large, and the steel plate is damaged. The use is more convenient and more scientific. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The second card plate 8 is installed on the top of the base 1, and the second card plate 8 is slidably connected to the top of the base 1, so that the second card plate 8 can move on the top of the base 1, the slider 10 extends to the inside of the cavity 11 and is threadedly connected to the threaded rod 12, so that the slider 10 can move on the threaded rod 12, both ends of the threaded rod 12 are rotatably connected to the inside of the cavity 11, so that the threaded rod 12 can rotate inside the cavity 12, one end of the threaded rod 12 extends to the inside of the base 1 and is connected to the rotating motor 13, so that the rotating motor 13 is installed inside the base 1, and the control button 2 is electrically connected to the battery 3, the processor 4, the multi-layer telescopic rod 7, the pressure sensor 9, and the rotating motor 13 through wires.

[0025] The working process of the utility model is as follows: when using the clamp for the transformer oil tank steel plate, first set the clamping pressure value of the clamp by clicking the control button 2. After the setting is completed, place the device on the transformer oil tank steel plate. After the placement is completed, click the start button on the control button 2 to make the rotating motor 13 run, drive the threaded rod 12 to rotate, so that the slider 10 moves on the threaded rod 12, thereby driving the second clamping plate 8 to move on the top of the base 1.
