Description

Technical Field

[0001] This application relates to the field of transformer technology, specifically a transformer tank flipping device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer). Transformers can be classified according to their application as follows: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformer test transformers, angle transformers, high-current transformers, and excitation transformers.

[0003] Transformers typically consist of an outer casing and internal transformer components. During the production and processing of transformers, quality control of the transformer casing is crucial to ensure the safety and stability of subsequent equipment use. However, during the inspection of the transformer casing, it is often necessary to flip the casing to monitor various parts. However, existing flipping methods mostly rely on manual flipping, which is time-consuming, labor-intensive, and difficult to control the flipping angle, thus having certain shortcomings.

[0004] Therefore, this application provides a transformer tank flipping device to solve the above problems. Utility Model Content

[0005] This application provides a transformer tank flipping device, which aims to solve the problems of existing flipping methods mentioned in the background art, which mostly rely on manual flipping, are time-consuming and labor-intensive, and have certain shortcomings due to the difficulty in controlling the flipping angle.

[0006] To achieve the above objectives, this application provides the following technical solution: a transformer housing tilting device, comprising a multi-angle rotation mechanism fixedly mounted on a base:

[0007] The multi-angle rotation mechanism includes an annular support frame fixedly mounted on a base. An inner annular support is rotatably mounted within the annular support frame. A drive motor is located on one side of the base, and a gear is fixedly mounted on the output end of the drive motor. A gear ring meshing with the gear is fixedly mounted on the inner annular support, and a servo motor is fixedly mounted on the inner annular support. A mounting bracket is fixedly mounted on the output end of the servo motor. Thus, when inspecting the transformer housing, the transformer housing base is mounted on the mounting bracket. Starting the servo motor drives the mounting bracket to rotate circumferentially in the horizontal plane, thereby achieving circumferential inspection of the transformer housing. Starting the drive motor drives the gear to rotate, which in turn drives the gear ring on the inner annular support to rotate, causing the inner annular support to flip within the annular support frame, achieving inspection of the top and bottom of the transformer housing. The entire flipping process requires no manual labor, saving time and effort, and allows for omnidirectional rotation of the transformer housing. The flipping angle is easily adjustable, and it is less likely to miss any areas.

[0008] Preferably, for mounting the transformer housing, the mounting bracket has several evenly spaced mounting holes for fixing the transformer housing base. This allows for convenient and quick assembly and disassembly.

[0009] Preferably, to enhance support, a cylinder is fixedly installed on the annular inner support at a position symmetrical to the servo motor, and a support plate is rotatably mounted on the output end of the cylinder. This ensures support strength and improves detection safety.

[0010] Preferably, to reduce wear, a plurality of circumferentially evenly distributed support rollers are rotatably mounted on the outer wall of the annular inner support, and the support rollers are in rolling contact with the inner wall of the annular support frame. This avoids the problem of high friction and excessive wear caused by direct contact between the annular support frame and the annular inner support.

[0011] Preferably, to protect the gear, a through-hole adapted to the gear is provided at the connection between the base and the annular support frame, and the gear is rotatably mounted in the cavity. This serves to protect the gear and reduce the impact of external factors on it.

[0012] Preferably, to adjust the installation spacing, the flipping device further includes a spacing adjustment mechanism. The adjustment mechanism includes a mounting slot plate fixedly mounted on the output end of the servo motor. The mounting slot plate has a sliding groove opposite to the support plate. A bidirectional lead screw is rotatably mounted within the sliding groove. One end of the bidirectional lead screw passes through the mounting slot plate and a knob is fixedly mounted at its end. Two symmetrically arranged sliders adapted to the sliding groove are screwed onto the bidirectional lead screw. The sliders are fixedly connected to a fixing frame. This allows for adjustment based on the required transformer housing model and size, achieving compatibility with different transformer housings and broad applicability.

[0013] This flipping device mounts the transformer housing base onto a fixed frame. Activating the servo motor causes the fixed frame to rotate circumferentially on a horizontal plane, thus enabling the detection of the transformer housing's outer perimeter. Activating the drive motor then rotates a gear, which in turn rotates a gear ring on the inner ring support, causing the inner ring support to flip within the ring support frame. This allows for the detection of the top and bottom of the transformer housing. The entire flipping process requires no manual labor, saving time and effort. It also allows for omnidirectional rotation of the transformer housing, with easily adjustable flipping angles, ensuring no areas are missed.

[0014] This flipping device, when the knob is turned, drives the bidirectional lead screw to rotate. The bidirectional lead screw causes two sliders to move in opposite directions within the slide groove, thereby adjusting the distance between the fixed brackets on the two sliders. This allows for adjustment based on the size and model of the transformer enclosure to be inspected, achieving the effect of adapting to different transformer enclosures, and has a wide range of applications.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides a transformer tank tilting device, such as... Figure 1-4 As shown, the flipping device includes a multi-angle rotation mechanism 2 fixedly mounted on the base 1:

[0024] The multi-angle rotation mechanism 2 includes an annular support frame 21 fixedly mounted on the base 1, an annular inner support 22 rotatably mounted inside the annular support frame 21, a drive motor 23 is provided on one side of the base 1, a gear 24 is fixedly mounted on the output end of the drive motor 23, a gear ring 25 meshing with the gear 24 is fixedly mounted on the annular inner support 22, a servo motor 26 is fixedly mounted on the annular inner support 22, and a fixing bracket 27 is fixedly mounted on the output end of the servo motor 26.

[0025] In use, the transformer housing base is installed on the fixed frame 27, and the servo motor 26 is started to drive the fixed frame 27 to rotate circumferentially on the horizontal plane, thereby realizing the detection of the outer periphery of the transformer housing. The drive motor 23 is started to drive the gear 24 to rotate, and the gear 24 drives the gear ring 25 on the annular inner support 22 to rotate, thereby making the annular inner support 22 flip within the annular support frame 21, realizing the detection of the top and bottom of the transformer housing. The entire flipping process does not require manual labor, saving time and effort, and can achieve 360-degree omnidirectional rotation of the transformer housing. The flipping angle is easy to adjust and is not easy to miss.

[0026] Specifically, the mounting bracket 27 has several evenly spaced mounting holes 210 for fixing the transformer housing base. In use, the multiple distributed mounting holes 210 facilitate the fixing of different transformer housings to the mounting bracket 27 with bolts, making assembly and disassembly convenient and quick.

[0027] More specifically, a cylinder 28 is fixedly installed on the inner ring support 22 at a position symmetrical to the servo motor 26, and a support plate 29 is rotatably mounted on the output end of the cylinder 28. In use, after the transformer housing is installed on the fixed frame 27, the cylinder 28 is activated. The cylinder 28 pushes the support plate 29 onto the side of the transformer housing opposite to the mounting surface of the fixed frame 27 through its output end. This allows the support plate 29 to support the transformer housing from the bottom while rotating with the transformer housing, ensuring support strength and improving testing safety.

[0028] Furthermore, several circumferentially evenly distributed support rollers 211 are rotatably mounted on the outer wall of the annular inner support 22, and the support rollers 211 are in rolling connection with the inner wall of the annular support frame 21. In use, when the annular inner support 22 rotates within the annular support frame 21, it is supported by the support rollers 211 on the annular support frame 21, achieving rotation through rolling. This avoids the problem of high friction and wear caused by direct contact between the annular support frame 21 and the annular inner support 22.

[0029] Furthermore, a through-hole cavity 212 adapted to the gear 24 is provided at the connection between the base 1 and the annular support frame 21. The gear 24 is rotatably installed in the cavity 212. In use, the output end of the drive motor 23 is inserted into the cavity 212, and the gear 24 is placed in the cavity 212, which protects the gear 24 and reduces the impact of external factors on the gear 24.

[0030] Example 2

[0031] Unlike Embodiment 1, when fixing the transformer housing with the fixing frame 27, the spacing between the mounting points of the transformer housing bases of different models and sizes is often different and needs to be adjusted. Therefore, the flipping device also includes a spacing adjustment mechanism 3. The spacing adjustment mechanism 3 includes a mounting slot plate 31 fixedly mounted on the output end of the servo motor 26. The mounting slot plate 31 has a sliding groove 32 that is opposite to the support plate 29. A bidirectional lead screw 33 is rotatably mounted in the sliding groove 32. One end of the bidirectional lead screw 33 passes through the mounting slot plate 31 and a knob 34 is fixedly mounted at the end. Two symmetrically arranged sliders 35 that are adapted to the sliding groove 32 are screwed onto the bidirectional lead screw 33. The sliders 35 are fixedly connected to the fixing frame 27.

[0032] In use, turn the knob 34, which drives the bidirectional lead screw 33 to rotate. The bidirectional lead screw 33 drives the two sliders 35 to move in opposite directions within the slide groove 32, thereby adjusting the distance of the fixing bracket 27 on the two sliders 35. This allows for adjustment based on the size of the transformer box to be inspected, achieving the effect of adapting to different transformer boxes and making it widely applicable.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
