[0004] During use, it was found that the above patent uses a suction cup to adsorb and clamp the transformer. It is known that in practice the surface of the transformer is covered with fin-shaped heat sinks, and the overall mass of the transformer is relatively high. The suction cup adsorption method is difficult to provide effective adsorption force due to insufficient air pressure difference. There is a risk of falling off during the adsorption and clamping process, and the risk factor is high, and the safety of use is difficult to guarantee. For this reason, we propose a clamp device for transformer detection to solve the above defects. Utility Model Content

[0015] Compared with the related art, the clamp device for transformer detection proposed by the utility model has the following beneficial effects:

[0016] In the utility model, a clamp device for transformer detection is described, through a driving mechanism, a synchronous motor is used to drive a small gear to rotate, and the small gear drives the middle gear to rotate. When the small gear drives the middle gear to rotate, the rotation speed obtained by the middle gear is reduced and the torque is increased. Subsequently, the middle gear drives the large gear to rotate, and the rotation speed of the large gear is reduced again, and the torque is further increased, so that the rotation speed of the threaded rod fixedly connected to the large gear is reduced and the torque is increased. Then, under the drive of the threaded rod, the slide seats on both sides thereof approach or move away from each other at a steady speed to clamp the transformer. The setting of the above-mentioned driving mechanism makes the process of clamping the transformer more stable, thereby improving the practicality and safety.

[0017] In the utility model, a clamp device for transformer detection is provided with an anti-slip mechanism. When the vertical clamping plate clamps the transformer on the inside, the first transformer support plate and the second transformer support plate provided on the lower side of the vertical clamping plate are located at the bottom of the transformer, supporting the transformer. At the same time, the electromagnet is started, and the slider is pushed out of the installation groove by the repulsion of the same magnetic poles, so that the convex teeth on the slider are engaged with the tooth grooves on the side of the second transformer support plate, so that the positions of the first transformer support plate and the second transformer support plate are relatively locked and will not slip, thereby making the supporting system at the bottom of the transformer in a locked state. Even if the clamping force of the vertical clamping plates on both sides on the transformer is insufficient, the transformer will not have the risk of slipping due to the stable supporting system at the bottom. The provision of the above-mentioned anti-slip mechanism further enhances the safety of use of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 A clamp device for transformer detection includes a flat plate 1, a rope 2 is arranged on the upper side of the flat plate 1, a hanging plate 3 is connected to the upper end of the rope 2, a driving mechanism is arranged on the surface of the flat plate 1, a threaded rod 8 is rotatably installed at the bottom of the flat plate 1, a round rod 9 is arranged on the side of the threaded rod 8, two slides 11 are symmetrically threaded on the threaded rod 8, two large gears 10 are symmetrically installed on the threaded rod 8, a vertical clamping plate 12 is fixedly installed at the bottom of the slide 11, a transformer 22 is clamped between the two vertical clamping plates 12, a first transformer support plate 14 is fixedly installed on the inner side of the right vertical clamping plate 12, a second transformer support plate 15 is fixedly installed on the inner side of the left vertical clamping plate 12, an anti-slip mechanism is arranged between the first transformer support plate 14 and the second transformer support plate 15, a hook 4 is fixedly installed on the hanging plate 3, and the internal threads of the slides 11 on both sides are in opposite directions to the threaded connection of the threaded rod 8.

[0025] With the above structure, the internal threads of the two side slides 11 and the threaded rod 8 are arranged in opposite directions, so that when the threaded rod 8 rotates to drive the slide 11, the slides 11 on both sides move in opposite directions, that is, they move away from or close to each other.

[0026] In this embodiment, the driving mechanism includes a synchronous motor 5, a pinion 6 and a center gear 7. The synchronous motor 5 is fixedly mounted on the plate 1. The pinion 6 is connected to the shaft coupling at the output end of the synchronous motor 5 and the pinion 6 is meshed with the center gear 7. The center gear 7 is rotatably mounted on the plate 1 and the center gear 7 is meshed with the large gear 10.

[0027] Through the above structure, the synchronous motor 5 drives the small gear 6 to rotate, and the small gear 6 drives the middle gear 7 to rotate, then the speed obtained by the middle gear 7 is reduced, and the torque is increased, and then the middle gear 7 drives the large gear 10 to rotate, then the speed of the large gear 10 is reduced again, and the torque is further increased, so that the speed of the threaded rod 8 fixedly connected to the large gear 10 is reduced.

[0028] In this embodiment, the anti-slip mechanism includes a mounting groove 16, a slider 18 and a tooth groove 21. An electromagnet 17 is fixedly installed on the inner side of the mounting groove 16. The slider 18 is in sliding contact with the inner wall of the mounting groove 16. A telescopic rod 19 is fixedly connected between the electromagnet 17 and the slider 18. A convex tooth 20 is provided on the side of the slider 18. The tooth groove 21 is opened on the inner side of the second transformer support plate 15.

[0029] Through the above structure, the electromagnet 17 is energized, and the slider 18 is pushed out of the installation groove 16 by the repulsion of the same magnetic poles, so that the protruding teeth 20 on the slider 18 are engaged in the tooth grooves 21 on the side of the second transformer support plate 15, so that the positions of the first transformer support plate 14 and the second transformer support plate 15 are relatively locked and will not slip, thereby making the supporting system at the bottom of the transformer 22 in a locked state.

[0030] In this embodiment, the rope 2 is a steel strand.

[0031] Through the above structure, the steel strand has good tensile properties, so that the rope 2 has good load-bearing capacity.

[0032] In this embodiment, the round rod 9 is fixedly installed at the bottom of the flat plate 1 and the round rod 9 slides through the sliding seat 11 .

[0033] Through the above structure, the arrangement of the round rod 9 enables the slide seat 11 to maintain a sliding connection with the round rod 9 when it slides under the drive of the threaded rod 8, and the round rod 9 provides a stable guiding effect during its sliding process.

[0034] In this embodiment, the first transformer support plate 14 and the second transformer support plate 15 are in a staggered distribution relationship with each other.

[0035] In this embodiment, a plurality of ribs 13 are disposed on the back side of the vertical clamping plate 12 .

[0036] Through the above structure, the provision of the ribs 13 strengthens the lateral pressure bearing capacity of the vertical clamping plate 12, so that the vertical clamping plate 12 can provide a more stable clamping force.

[0037] In this embodiment, the protruding teeth 20 are matched with the tooth grooves 21, and the slider 18 is made of permanent magnet material.

[0038] Through the above structure, the permanent magnet has two magnetic poles, which cooperate well with the electromagnet 17. The magnetic poles in the same direction repel each other, and the magnetic poles in opposite directions attract each other. By passing different current directions into the electromagnet 17 to change the direction of the magnetic pole of the electromagnet 17, the interaction force between the electromagnet 17 and the slider 18 can be changed, thereby realizing the operation of pushing the outer side of the slider 18 out of the installation groove 16 and retracting the slider 18 into the installation groove 16.

[0039] When the lifting tool 22 is in use, the hook 4 is hung on the lifting tool, the synchronous motor 5 is started to drive the threaded rod 8 to rotate, and the threaded rod 8 drives the symmetrical slides 11 on both sides to approach each other, so that the vertical clamping plates 12 on the lower side of the slide 11 approach each other to clamp the transformer 22. When the vertical clamping plates 12 on both sides form a clamping force on the transformer 22, the first transformer support plate 14 and the second transformer support plate 15 at the bottom are located at the bottom of the transformer 22 and are in a cross-engaged state. Subsequently, the electromagnet 17 is started, and the outer edge of the slider 18 is pushed out of the mounting groove 16 by the repulsion of the same magnetic poles, so that the convex teeth 20 on the slider 18 are engaged with the tooth grooves 21 on the side of the second transformer support plate 15, so that the positions of the first transformer support plate 14 and the second transformer support plate 15 are relatively locked, and no slippage occurs, thereby making the supporting system at the bottom of the transformer 22 in a locked state. After locking, the lifting tool can be started to lift and detect.

[0040] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.

Any figure mark in the claims should not be regarded as limiting the claims involved.
