Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a quick disassembly device for transformer maintenance. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. When repairing a transformer, its main body needs to be disassembled for repair.

[0003] At present, the coils of fully automatic transformers need to be manually disassembled during maintenance. Maintenance personnel manually pull the tape and aluminum wire to separate them. However, since the coils of fully automatic transformers are generally large in size, the time required to disassemble the tape and aluminum wire is relatively long, resulting in low overall maintenance efficiency.

[0004] For example, a quick disassembly device for transformer maintenance disclosed in Chinese patent CN219226052U comprises: a main frame, a motor is arranged on the top of the main frame, a rotating rod is connected to the output end of the motor, a rotating block is fixedly connected to the top of the main frame, and the rotating block is rotatably connected to the first threaded rod. The fully automatic quick disassembly device for transformer maintenance forms a coil disassembly structure by arranging a motor, a rotating rod, a first threaded rod, a fixed disk, an adjusting disk and a rotating block. The coil is inserted into the first threaded rod, and then the tape and aluminum wire of the coil are pulled by the rotating rod to disassemble. The operation process is simple, which is convenient for the staff to quickly disassemble and repair the transformer and improve the overall maintenance efficiency. By arranging an outer frame, a second threaded rod, a sliding block, a universal wheel and a push handle, the second threaded rod can be rotated so that the universal wheel supports the device, which is convenient for the staff to carry the device to move in different scenes.

[0005] However, the rapid splitting device for transformer maintenance may generate vibration when splitting the transformer, and the generated vibration may affect the operation process and the splitting effect.

[0006] Therefore, we proposed a quick disassembly device for transformer maintenance to solve the above problems. Utility Model Content

[0025] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0026] Embodiment 1: A quick disassembly device for transformer maintenance, comprising an operating table 1 and a square slot 2, wherein the square slot 2 runs through the upper surface of the operating table 1, a buffer mechanism is provided on the bottom surface of the operating table 1, and an adjustment mechanism is provided on the upper surface of the operating table 1;

[0027] The buffer mechanism includes a connecting unit and a sliding unit. The connecting unit includes a damping rod 3, a fixed base 301, a fixed block 303, a rotating shaft groove 304 and a rotating shaft 305.

By arranging a buffer mechanism on the bottom surface of the operating table 1, when vibration is generated during the splitting process, the fixed block 303 fixedly installed on the bottom surface of the operating table 1 can transmit the vibration downward so that the rotating shaft 305 rotates to drive the oblique connecting plate 306 to rotate, squeeze the slider 308 to squeeze the compression spring 309 to buffer the vibration, and cooperate with the damping rod 3 to minimize the impact of the vibration.

[0029] When the transformer is disassembled and vibration is generated, the vibration is transmitted downward, causing the rotating shaft 305 installed on the inner wall of the rotating shaft groove 304 to rotate to both sides, driving the oblique connecting plate 306 to rotate, squeezing the slider 308, causing the slider 308 to slide on the inner wall of the slide groove 307, squeezing the compression spring 309, thanks to the elasticity of the compression spring 309 itself, the restoring elastic force is generated to buffer the squeezing force caused by the vibration, and the damping rod 3 connected to the bottom surface of the operating table 1 is used together to effectively buffer the vibration, so that the disassembly process can be carried out stably.

[0031] The rotating unit includes a first fixed plate 4, a first drive motor 401, a transmission shaft 402, a fixed circular plate 403, a positioning rod 404, a second fixed plate 405, a first cylinder 406, a telescopic column 407 and a connecting bearing 408.

[0032] The transformer is placed on the bottom surface of the placement groove 418, and the second drive motor 411 drives the threaded column in the transmission member 412 to rotate. Through the threaded engagement, the moving block installed on the outer surface of the threaded column drives the support plate 413 to rise on the outer surface of the threaded column and drives the transformer to rise. The transformer rises to the positioning height aligned with the positioning rod 404 and stops rising.

When the rotation split is performed, the placement table 417 descends to cancel the lifting. The first drive motor 401 works to drive the transmission shaft 402 to rotate, thereby driving the transformer to rotate through the positioning rod 404. When the positioning rod 404 on the other side rotates, it rotates around the connecting bearing 408 and the staff splits the coil of the transformer.
