For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The following is combined with Figure 1-5 The utility model is further described.

[0027] In order to solve the problems existing in the background technology, the present application proposes the following technical scheme: it includes a test table 1, on which two groups of movable plates 2 are slidably installed, and connecting columns 13 are fixedly installed on opposite sides of the two groups of movable plates 2. A clamping plate 3 is rotatably installed on the end of the connecting column 13 away from the movable plate 2. The two groups of clamping plates 3 are used to clamp and fix the transformer to be detected for fault. A gear 8 is fixedly installed on one side of the clamping plate 3, and the gear 8 is slidably sleeved on the outside of the connecting column 13. A slide groove 6 is opened on the movable plate 2, and a slider 7 is slidably installed in the slide groove 6. A tooth plate 12 is fixedly installed on one side of the slider 7, and the tooth plate 12 is meshed with the gear 8.

[0028] The two groups of clamps 3 are brought close to each other to clamp and fix the transformer, pushing the slider 7 to move, the slider 7 drives the tooth plate 12 to move, the tooth plate 12 causes the gear 8 to rotate, and the gear 8 drives the clamp 3 to rotate, so that the transformer clamped and fixed on the clamp 3 is flipped. The transformer can be flipped by moving the slider 7, and there is no need to remove the transformer from between the two groups of clamps 3 and re-fix it, which improves the efficiency of transformer fault detection and reduces the labor intensity of fault detection personnel.

[0029] It is further explained that a mounting plate 4 is fixedly connected to a surface of the movable plate 2 away from the tooth plate 12 , an electric push rod 5 is fixedly mounted on the mounting plate 4 , and an end of the electric push rod 5 away from the mounting plate 4 is fixedly connected to one side of the slider 7 .

[0030] The mounting plate 4 provides installation conditions for the electric push rod 5, and the electric push rod 5 can push the slider 7 to move left and right in the slide groove 6. The slider 7 cooperates with the tooth plate 12 and the gear 8 to realize the forward and reverse rotation of the clamping plate 3, which is convenient for adjusting the angle of the transformer. The setting of the electric push rod 5 improves the convenience of using the device. The slide groove 6 guides and limits the slider 7, improves the stability of the tooth plate 12 when moving, and thus improves the stability when flipping the transformer.

[0031] It is further explained that a limit groove 15 is provided on the detection platform 1, and a motor 17 is fixedly installed inside the detection platform 1. A threaded rod 16 is coaxially fixedly connected to the driving shaft of the motor 17. The threaded rod 16 is rotatably installed in the limit groove 15. The external thread of the threaded rod 16 is connected to the limit plate 10, and the upper end of the limit plate 10 is fixedly connected to the bottom end of the movable plate 2.

[0032] The motor 17 drives the threaded rod 16 to rotate, and the threaded rod 16 pushes the two groups of limit plates 10 to be relatively close or relatively far away. When the two groups of limit plates 10 drive the two groups of movable plates 2 to be relatively close, the movable plates 2 drive the clamping plates 3 to be close to each other. The two groups of clamping plates 3 clamp and fix the transformer to ensure that the transformer will not shift during fault detection, thereby ensuring the accuracy of the detection result. The limit groove 15 guides and limits the limit plate 10 to prevent the limit plate 10 from rotating itself when the threaded rod 16 rotates, thereby improving the stability of the limit plate 10 when moving in the limit groove 15.

[0033] It is further explained that a limiting hole 14 is provided on the movable plate 2, a locking rod 22 is slidably installed in the limiting hole 14, and a plurality of groups of locking holes 9 are provided on the gear 8. In the present application, 7 groups of locking holes 9 are provided, and the number of locking holes 9 can be increased or decreased according to actual needs, and the locking holes 9 are adapted to the locking rod 22.

[0034] After the clamp plate 3 is flipped to a certain angle, the locking rod 22 moves in the limiting hole 14, and one end of the locking rod 22 is inserted into the locking hole 9. The locking rod 22 cooperates with the limiting hole 14 and the locking hole 9 to limit the gear 8 so that the gear 8 no longer rotates, thereby locking the transformer after flipping, avoiding the transformer from shifting during the fault detection process and ensuring the accuracy of the detection result.

[0035] It is further explained that a locking cylinder 11 is fixedly installed on the side of the movable plate 2 away from the tooth plate 12, a movable groove 18 is opened on the outer surface of the locking cylinder 11, a push rod 20 is slidably installed in the movable groove 18, the push rod 20 is fixedly connected to the outer surface of the locking rod 22, a return spring 21 is arranged in the locking cylinder 11, one end of the return spring 21 is fixedly connected to one end of the locking rod 22, and the other end of the return spring 21 is fixedly connected to the bottom of the locking cylinder 11.

[0036] When the transformer needs to be flipped, the push rod 20 is pushed, and the push rod 20 drives the locking rod 22 to move. The movement of the locking rod 22 compresses the reset spring 21, so that the locking rod 22 moves out of the locking hole 9 on the gear 8, and the restriction of the locking rod 22 on the gear 8 is released. At this time, the electric push rod 5 can flip the transformer and adjust the transformer angle for fault detection. After the transformer is flipped, the push rod 20 is released, and the compressed reset spring 21 drives the locking rod 22 to move to restore the initial state. The locking rod 22 is inserted into the locking hole 9 to restrict the gear 8. The setting of the reset spring 21 enables the locking rod 22 to automatically reset, thereby improving the convenience of the device when used.

[0037] It is further explained that a limiting groove 19 is also provided on the outer surface of the locking cylinder 11 , and the limiting groove 19 is connected to the moving groove 18 .

[0038] When releasing the transformer flip lock, after pushing the push rod 20 to one side of the movable groove 18, the push rod 20 is rotated to move the push rod 20 into the limiting groove 19, and the compressed return spring 21 makes the push rod 20 stably in the limiting groove 19, so that when flipping the transformer, there is no need to push the push rod 20 by hand all the time, which is convenient for fault detection personnel to use and improves the convenience of using the device. After the transformer is flipped, the push rod 20 is pushed out of the limiting groove 19 and then rotated to the movable groove 18, and the return spring 21 can push the locking rod 22 into the locking hole 9 to complete the locking.

[0039] Specific reference is made to the following operations: the motor 17 drives the threaded rod 16 to rotate, the threaded rod 16 pushes the two groups of limit plates 10 to move relatively close, the two groups of limit plates 10 drive the two groups of movable plates 2 and the clamping plate 3 to move relatively close, and the transformer placed between the two groups of clamping plates 3 is clamped and fixed; the push rod 20 is pushed into the limit groove 19, the electric push rod 5 pushes the slider 7 to move in the slide groove 6, the slider 7 drives the tooth plate 12 to move, the tooth plate 12 makes the gear 8 rotate, the gear 8 drives the clamping plate 3 to rotate, so that the transformer clamped and fixed on the clamping plate 3 is flipped, and after the flipping is completed, the push rod 20 is pushed back into the movable groove 18, and the compressed return spring 21 drives the locking rod 22 to move to restore the initial state, and the locking rod 22 is inserted into the locking hole 9 to limit the gear 8, thereby locking the transformer after flipping.
