[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components include a primary coil, a secondary coil, and an iron core (magnetic core). Its primary functions include voltage conversion, current conversion, impedance conversion, isolation, and voltage regulation (magnetic saturation transformer). Transformers are essential equipment for power transmission and distribution and are widely used in industry, agriculture, transportation, urban communities, and other fields.

[0003] Small transformers are usually installed at high altitudes. Two columns need to be installed on the ground first, and then the small transformer is installed between the two columns.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] In the present invention, the first hydraulic rod is started to drive the sliding jacking plate to move downward, the sliding jacking plate is forced to drive the lifting platform, and the lifting platform is forced to drive the supporting slider, which moves downward to drive the transformer body, causing the first installation channel steel to fall onto the second installation channel steel, and then the second hydraulic rod is started to drive the supporting push plate to move, and the movement of the supporting push plate drives the supporting slider to reset, and the transformer body is placed.

[0035] In the present invention, when the supporting feet are in effective contact with the ground, the adjusting screw stops rotating, and the four supporting feet support the load-bearing base plate. By adding adjustable supporting feet to the stable support mechanism of the transformer installation lifting platform, during the installation of the transformer body, the adjusting screw is adjusted in conjunction with the supporting feet to form a stable support for the load-bearing base plate, and each individually adjustable supporting foot can be individually leveled according to the environment, thereby effectively improving the applicability of the device.

[0036] In the present invention, the fixed plate moves upward to drive the hinged connecting rod, and the hinged connecting rod is forced to drive the connecting slider, and the connecting slider is forced to slide in the fourth slide groove, and the hinged connecting rod slides and expands, causing the ladder connecting plates to slide and expand. By adding an automatically adjustable ladder connecting plate to the stable support mechanism of the transformer installation lifting platform, during the installation of the transformer body, when the transformer body is jacked up, the expanded ladder connecting plate forms a ladder, which is convenient for workers to climb up to fix the first installation channel steel and the second installation channel steel, thereby effectively improving the practicality of the device.

[0037] In the present invention, the transformer body is placed on the supporting slider, and then the transformer body is installed, and the two clamping rings are respectively clamped on one side of the column. By designing a stable support mechanism of the lifting platform for transformer installation and adding an adjustable clamping ring, during the installation of the transformer body, the driving motor is started to cooperate with the adjusting threaded rod to adjust the two bearing sliding blocks, so that transformer bodies of different sizes can be placed easily, and the bearing sliding block moves to adjust the spacing between the two clamping rings, so that the clamping ring can adapt to columns with different spacings, thereby ensuring that the transformer body can be placed in the middle position of the two columns, effectively improving the accuracy of installation.

[0038] In the present invention, the telescopic rod of the second hydraulic rod pushes the support push plate, and the support push plate moves under the force, driving the support slider to move, and the movement of the support slider drives the second rotating roller to roll. By designing a stable support mechanism of the lifting platform for transformer installation and adding the first rotating roller and the second rotating roller, during the installation of the transformer body, the first rotating roller assists the bearing sliding block to move, and the second rotating roller assists the support slider to move, thereby reducing friction and wear. In addition, due to their rolling characteristics, the first rotating roller and the second rotating roller can withstand higher loads, thereby effectively improving the practicality of the device.

[0055] Working principle:

[0056] In the first step, when the transformer is installed using the lifting platform stable support mechanism, push the bearing base plate 1 to the side of the column 18, and the bearing base plate 1 is forced to drive the self-locking universal wheel 11 to roll. When the two clamping rings 45 are clamped on the side of the column 18, the self-locking universal wheel 11 is self-locked and fixed. Then, the adjusting screw 14 is rotated to drive the supporting foot 15 to support the bearing base plate 1, and the first hydraulic rod 23 is started. The telescopic rod of the first hydraulic rod 23 drives the sliding jacking plate 22 to move upward, and the sliding jacking plate 22 is forced to move in the first slide groove 2. 1, the sliding jacking plate 22 moves upward to drive the lifting platform 3, the lifting platform 3 is forced to drive the bearing sliding block 34, the bearing sliding block 34 is forced to drive the supporting slider 37 to move upward, when the supporting slider 37 is lifted to the side beyond the second installation channel 19, then the second hydraulic rod 24 is started, the telescopic rod of the second hydraulic rod 24 drives the supporting push plate 38 to move, the supporting push plate 38 is forced to drive the supporting slider 37, the supporting slider 37 is forced to roll on the second rotating roller 36, and the movement of the supporting slider 37 drives the transformer The transformer body 16 moves, and when the support slider 37 drives the transformer body 16 to be on the second installation channel steel 19, the first hydraulic rod 23 is started to drive the sliding jacking plate 22 to move downward, and the sliding jacking plate 22 is driven by force to drive the lifting platform 3, and the lifting platform 3 is driven by force to drive the supporting slider 37. The supporting slider 37 moves downward to drive the transformer body 16, causing the first installation channel steel 17 to fall onto the second installation channel steel 19, and then the second hydraulic rod 24 is started to drive the supporting push plate 38 to move, and the supporting push plate 38 moves to drive the supporting slider 37 to reset, and the transformer body 16 is placed. By adding the lifting platform 3 and the supporting slider 37 to the stable support mechanism for the transformer installation lifting platform, during the installation of the transformer body 16, the first hydraulic rod 23 cooperates with the sliding jacking plate 22 to drive the lifting platform 3 to lift the transformer body 16, and the second hydraulic rod 24 cooperates with the supporting push plate 38 to drive the supporting slider 37 to push the transformer body 16, so that the installation of the transformer body 16 can be stably completed, effectively improving the safety of the installation.

[0057] The second step is to use the lifting platform stabilizing support mechanism for transformer installation, push the bearing base plate 1 to one side of the column 18, and the bearing base plate 1 is forced to drive the self-locking universal wheel 11 to roll. When the two clamping rings 45 are clamped on one side of the column 18, the self-locking universal wheel 11 is self-locked and fixed, and the adjusting screw 14 is turned. The adjusting screw 14 is forced to rotate in the support block 13, and the adjusting screw 14 is forced to rotate on the support foot 15. The adjusting screw 14 thread adjusts the position of the support foot 15. When the support foot 15 is effectively in contact with the ground, the rotation of the adjusting screw 14 is stopped. The four support feet 15 support the bearing base plate 1. By adding adjustable support feet 15 to the stable support mechanism for the lifting platform for transformer installation, the adjusting screw 14 is adjusted in conjunction with the support feet 15 during the installation of the transformer body 16, thereby forming a stable support for the bearing base plate 1, and each individually adjustable support foot 15 can be individually leveled according to the environment, thereby effectively improving the applicability of the device.

[0058] In the third step, when the transformer is installed using a lifting platform stabilizing support mechanism, push the bearing base plate 1 to one side of the column 18, the two clamping rings 45 are clamped on one side of the column 18, and then the self-locking universal wheel 11 is self-locked and fixed, and the support feet 15 are adjusted to support the bearing base plate 1. In the process of the first hydraulic rod 23 starting to drive the sliding jacking plate 22 to jack up, the sliding jacking plate 22 is forced to drive the lifting platform 3 to move, and the movement of the lifting platform 3 drives the bearing sliding block 34 to move, and the bearing sliding block 34 is forced to drive the second fixing rod 43 to move, and the second fixing rod 43 is forced to move and drive the fixing plate 44, and the fixing plate 44 is forced to move The ladder connecting plates 5 are moved upward, and the fixed plate 44 moves upward to drive the hinged link 53, and the hinged link 53 is forced to drive the connecting slider 52, and the connecting slider 52 is forced to slide in the fourth slide groove 51, and the hinged link 53 slides and unfolds, causing the ladder connecting plates 5 to slide and unfold. By adding an automatically adjustable ladder connecting plate 5 to the stable support mechanism of the transformer installation lifting platform, during the installation of the transformer body 16, when the transformer body 16 is jacked up, the unfolded ladder connecting plate 5 forms a ladder, which is convenient for the staff to climb up to fix the first installation channel steel 17 and the second installation channel steel 19, thereby effectively improving the practicability of the device.

[0059] The fourth step is to use the lifting platform stable support mechanism for transformer installation, adjust the clamping ring 45 according to the distance between the two columns 18, start the driving motor 33, and the output shaft of the driving motor 33 drives the adjusting threaded rod 32 to rotate, and the adjusting threaded rod 32 rotates to adjust the distance between the two bearing sliding blocks 34. Because the thread directions of the two bearing sliding blocks 34 are opposite, the two bearing sliding blocks 34 move relative to each other, and the bearing sliding blocks 34 are forced to move and drive the second fixing rod 43 to move, and the second fixing rod 43 is forced to move and drive the fixing plate 44, and the fixing plate 44 is forced to move and drive the clamping ring 45. When the two clamping rings 45 correspond to the positions of the columns 18, turn off the driving motor 33, and then the transformer itself is moved. The body 16 is placed on the supporting slider 37, and then the transformer body 16 is installed, and the two clamping rings 45 are respectively clamped on one side of the column 18. By designing a stable support mechanism for the transformer installation lifting platform and adding an adjustable clamping ring 45, during the installation of the transformer body 16, the driving motor 33 is started and the adjusting threaded rod 32 is coordinated to adjust the two bearing sliding blocks 34, so that transformer bodies 16 of different sizes can be placed easily, and the bearing sliding block 34 moves to adjust the spacing between the two clamping rings 45, so that the clamping ring 45 can adapt to columns 18 with different spacings, thereby ensuring that the transformer body 16 can be placed in the middle position of the two columns 18, effectively improving the accuracy of installation.

[0060] In the fifth step, when the transformer is installed using the lifting platform stable support mechanism, when the drive motor 33 is started, the output shaft of the drive motor 33 drives the adjusting threaded rod 32 to rotate, and the adjusting threaded rod 32 rotates to adjust the distance between the two bearing sliding blocks 34. Because the thread directions of the two bearing sliding blocks 34 are opposite, the two bearing sliding blocks 34 move relative to each other, and the movement of the bearing sliding blocks 34 drives the first rotating roller 35 to roll. The first rotating roller 35 is forced to roll in the second slide groove 31. When the second hydraulic rod 24 is started, the telescopic rod of the second hydraulic rod 24 pushes the support push plate 38, and the support The push plate 38 is moved by the force, driving the support slider 37 to move, and the movement of the support slider 37 drives the second rotating roller 36 to roll. By designing a stable support mechanism of the lifting platform for transformer installation and adding the first rotating roller 35 and the second rotating roller 36, during the installation of the transformer body 16, the first rotating roller 35 assists the bearing sliding block 34 to move, and the second rotating roller 36 assists the support slider 37 to move, thereby reducing friction and wear.
