Description

Technical Field

[0001] The utility model relates to the technical field of transformer detection, in particular to a fixing fixture for transformer detection. Background Art

[0002] Transformer testing is a process involving multiple aspects and steps. Its main purpose is to ensure the safe and stable operation of the transformer and meet the relevant performance requirements. During the transformer testing process, each part of the transformer needs to be accurately measured and inspected. The fixture can firmly fix the transformer's coils, cores and other components to prevent movement or vibration during the test, thereby ensuring the accuracy and reliability of the measurement results. Therefore, the fixture plays a role in fixing, stabilizing, improving safety and efficiency in transformer testing, and is an indispensable tool in the transformer testing process.

[0003] In the prior art, suction cup clamps are generally used as fixing tools during transformer inspection, which is mainly due to the stable and reliable fixing performance of the suction cup clamps. By effectively using the suction cup clamps, the transformer can be ensured to be stable and motionless during the inspection process, thereby greatly improving the accuracy and reliability of the inspection results. In addition, this fixing method also helps to protect the safety of the inspection equipment and operators and reduce the risks that may be caused by equipment movement or vibration. However, although the suction cup clamp plays an important role in transformer inspection, it also has some obvious defects in practical applications. In particular, when the suction cup is used to fix the transformer on a vertical plane, the influence of gravity cannot be ignored. In a vertical state, the adsorption effect of the suction cup may be greatly affected, resulting in a significant reduction in its fixing ability. In particular, when the inspection equipment has a large amplitude during the inspection process, it may not be possible to ensure the stable fixation of the transformer by relying solely on the suction cup. At this time, it is often necessary to use additional auxiliary handrails or other fixing measures to enhance the stability of the fixation and prevent the transformer from accidentally falling off. Therefore, there are certain disadvantages. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Combination Figure 1-Figure 2 As shown, a fixing fixture for transformer detection of the utility model comprises a support 1 interconnected with a detection device,

[0040] The plate body 2 is fixedly mounted on a surface of the support 1 which is away from the detection device, and is perpendicular to the support 1;

[0041] The fixing clamping plate 3 is fixedly mounted on the side of the plate body 2, and is perpendicular to the plate body 2, and one side surface of the fixing clamping plate 3 is in contact with the surface of the transformer;

[0042] A movable clamp 4 is disposed on the other side of the plate body 2 and is used to fix the transformer to the surface of the fixing clamp plate 3;

[0043] The suction cup 5 is arranged on a side surface of the plate body 2 away from the support 1, and is in contact with the bottom of the transformer;

[0044] The gas communication component 6 is disposed on the plate body 2 and is mutually connected with the suction cup 5;

[0045] The abutment component 7 is disposed on one side surface of the fixing clamp plate 3 and is used to push the transformer to the surface of the suction cup 5 so as to draw air through the gas connection component 6 to fix the transformer.

[0046] Through the rotational displacement of the movable clamp 4, the transformer can be effectively pressed against the surface of the fixed clamp 3 to achieve preliminary fixation. On this basis, with the use of the suction cup 5 and the gas connecting component 6, the air in the suction cup 5 can be extracted, and the transformer can be firmly adsorbed on the surface of the suction cup 5 using the principle of atmospheric pressure. Finally, through the use of the resistance component 7, the transformer is further squeezed downward to ensure that it is firmly placed on the surface of the suction cup. This comprehensive fixing method effectively solves the problem faced when using a suction cup to fix the transformer on a vertical plane. The fixing fixture is suitable for partial outer casings and certain metal parts of the transformer, and the surface is often flat. The transformers described in the embodiments are all general terms for the transformer parts to be tested.

[0047] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 2 As shown; the movable clip 4 includes:

[0048] The driving motor 41 is fixedly mounted on a surface of the plate body 2 on one side close to the support 1;

[0049] An arc-shaped arm 42, one end of which is fixedly mounted on the output end of the driving motor 41, and can be rotated and displaced under the driving of the driving motor 41; and

[0050] The movable clamping plate 43 is fixedly installed on the other end of the arc arm 42, and can be displaced synchronously with the movement of the arc arm 42 to fix the transformer to the surface of the fixed clamping plate 3, wherein the driving motor 41 can drive the arc arm 42 to rotate, and the arc arm 42 will not conflict with the position of the plate body 2 during the rotation process, wherein the arc arm 42 can jointly drive the movable clamping plate 43 to rotate during the rotation process, so as to achieve the limitation and fixation of the left and right sides of the transformer.

[0051] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 2 As shown; eight connection seats 8 are fixedly installed on the surface of the side of the plate body 2 away from the pillar 1, wherein the number and distribution position of the suction cups 5 are mutually adapted to the connection seats 8, and the suction cups 5 are set through the connection seats 8. This array of connection seats with equal distance distribution can ensure that the suction cups 5 have uniform and stable support during installation. Each connection seat 8 serves as a fixing point for the suction cup 5, effectively dispersing the stress that may be generated by the suction cup 5 during the adsorption process, thereby improving the overall stability and safety, wherein a through hole is processed on the surface of the connection seat, and the suction cup 5 is inserted into the inner side of the through hole, and two nuts are threadedly connected on the surface of the suction cup 5, and the two nuts are respectively located on the upper and lower sides of the connection seat 8, so as to fix the position of the suction cup 5.

[0052] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 2 As shown; the gas communication component 6 includes:

[0053] The air chamber 61 is fixedly mounted on a side surface of the plate body 2 close to the support 1, and its interior is hollow;

[0054] There are two exhaust pipes 62, which are fixedly mounted on the front and rear sides of the plate body 2 and are interconnected with the suction cup 5, wherein one end of the exhaust pipe 62 is interconnected with the air chamber 61; and

[0055] The connecting pipe 63 is arranged on the air chamber 61, and one end of the connecting pipe 63 passes through and extends into the air chamber 61, wherein the other end of the connecting pipe 63 is interconnected with the exhaust end of the external exhaust device. The connecting pipe 63 can exhaust the air in the air chamber 61 during the exhaust process. Since the exhaust pipe 62 is interconnected with the air chamber 61, the air in the suction cup 5 can be exhausted, and the transformer can be firmly adsorbed on the surface of the suction cup 5 by using the principle of atmospheric pressure.

[0056] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 2 As shown; the conflict component 7 includes:

[0057] The first hinge seat 71 is fixedly mounted on one side surface of the fixed clamping plate 3;

[0058] The push cylinder 72 is hinged on the first hinge seat 71 and can be rotated and displaced according to the first hinge seat 71 as a circle;

[0059] An abutment member 73 rotatably connected to the end of the fixed clamping plate 3; and

[0060] The second articulated seat 74 is fixedly mounted on one side surface of the resistance member 73, wherein the output end of the pushing cylinder 72 is connected to the inner side of the second articulated seat 74. When the output end of the pushing cylinder 72 is extended or shortened, it can rotate through the first articulated seat 71 and the second articulated seat 74, and at the same time, it can also drive the resistance member 73 to rotate and move, so as to push the top of the transformer downward and firmly fix the transformer to the surface of the suction cup 5.

[0061] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 2As shown; the resistance member 73 is arranged in an L shape as a whole, wherein a hinge is arranged on the vertical end of the resistance member 73, and the resistance member 73 is connected to the end of the fixed splint 3 through the hinge, and the second hinge seat 74 is fixedly connected to the vertical end of the resistance member 73. The overall design of the resistance member 73 is L-shaped, and this shape gives it unique movement characteristics and functionality. A hinge is arranged on its vertical end, so that the resistance member 73 can rotate around the hinge point as the axis. Through this hinged manner, the resistance member 73 is connected to the end of the fixed splint 3, thereby forming a linkage with the fixed splint 3. When the transformer needs to be fixed, the fixed splint 3 and the movable clamp 4 work together to initially clamp the transformer in a fixed position. At this time, the lateral end of the resistance member 73 will abut against the surface of the transformer to form further fixation and limitation, wherein the hinge is preferably a hinge.

[0062] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 2 As shown; a mounting seat 9 is fixedly installed on the surface of the side of the plate body 2 away from the pillar 1, wherein a mounting groove is processed on the surface of the side of the plate body 2 away from the plate body 2, and a pressure sensor 10 is embedded in the mounting groove, which means that the pressure sensor 10 is tightly fitted with the mounting seat 9 and can accurately sense the pressure changes acting on the mounting seat 9. When the transformer is fixed on the plate body 2, its weight and fixing force will be transmitted to the mounting seat 9 through the plate body, and then act on the pressure sensor 10. In this way, the combination of the mounting seat 9 and the pressure sensor 10 not only provides a stable installation platform, but also can monitor the fixing state of the transformer in real time. This is of great significance for ensuring the safe fixing of the transformer and preventing accidental falling off. At the same time, by reading the output signal of the pressure sensor, the operator can also understand the fixing condition of the transformer so as to make timely adjustments or take corresponding measures.

[0063] The specific working principle of the utility model of a fixing fixture for transformer detection is as follows:

[0064] The transformer component to be tested is placed on the surface of the suction cup 5, and then the driving motor 41 can be started. The driving motor 41 drives the arc arm 42 to rotate. The arc arm 42 can drive the movable clamping plate 43 to move accordingly during the rotation. When the side surface of the transformer component is completely in contact with the fixed clamping plate 3 and the movable clamping plate 43, the driving motor 41 can be stopped, so that the transformer component is preliminarily fixed by the fixed clamping plate 3 and the movable clamping plate 43;

[0065] The external exhaust device extracts the gas in the air chamber 61 through the connecting pipe 63. Since the exhaust pipe 62 is connected to the air chamber 61, the air in the suction cup 5 can be extracted, and the transformer is firmly adsorbed on the surface of the suction cup 5 by using the atmospheric pressure principle, thereby achieving further fixation.

[0066] Start the pushing cylinder 72, which drives the resistance piece 73 to move, so that the lateral end of the resistance piece 73 will be against the surface of the transformer, further squeezing the transformer downward to ensure that it is firmly placed on the surface of the suction cup 5. At the same time, with the use of the pressure sensor 10, the pressure change acting on the mounting seat 9 can be accurately sensed. When the transformer is fixed on the plate body 2, its weight and fixing force will be transmitted to the mounting seat 9 through the plate body, and then act on the pressure sensor 10. By reading the output signal of the pressure sensor 10, the operator can also understand the fixing condition of the transformer so as to make timely adjustments or take corresponding measures. The use of multiple fixing means not only enhances the adsorption effect of the suction cup in a vertical state, but also greatly improves its fixing ability. Even if the transformer has a large amplitude during the detection process, it can ensure the stable fixation of the transformer without the need for additional auxiliary handrails or other fixing measures. This not only improves the fixing efficiency, but also reduces the complexity of operation.
