Description

Technical Field

[0001] This utility model belongs to the field of transformer installation technology, and in particular relates to a transformer that is easy to install. Background Technology

[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change AC voltage. Its main function is to realize voltage transformation in the process of power transmission to meet the needs of different power consumption scenarios. With the rapid development of technology, the demand for transformer installation is increasing accordingly.

[0003] The current installation of transformers requires the cooperation of many workers. When hoisting the transformer, it is pushed and moved to align the mounting holes with the bolt holes. Then, the transformer is slowly placed on the ground at the designated installation location. However, in actual installation, it is difficult for workers to align the mounting holes on the bottom of the transformer with the bolt holes in one go. Usually, the transformer needs to be hoisted up again and fine-tuned continuously until the mounting holes are aligned with the bolt holes. This method lacks an active positioning device, and the fine-tuning by many people over a long period of time requires a lot of manpower and time, resulting in low installation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a transformer that is easy to install. By setting a positioning mechanism, specifically, when the transformer deviates from its installation position, the bottom of one mounting bracket contacts the inclined surface of an adjacent positioning wedge and is pushed away from that wedge. When the mounting bracket moves down to half the height of the positioning wedge, the operator makes minor adjustments forward and backward, moving the positioning holes of the two mounting brackets to approximately the position above the positioning column. The bracket continues to be lowered until the positioning holes contact the top conical surface of the positioning column, and the mounting bracket moves under the guidance of the conical surface until it contacts the ground, completing the transformer positioning. This positioning mechanism first makes minor left and right adjustments when lowering the transformer to reduce the error range, and then uses the positioning column for more precise positioning, significantly improving the overall installation efficiency. It solves the problem of existing transformers lacking positioning devices, which requires multiple operators to assist in continuous fine-tuning, resulting in time-consuming, labor-intensive, and inefficient installation.

[0015] The connecting frame is arranged in a ring shape, and the I-beam block is used to prevent the positioning wedge block from rotating when it moves.

[0016] Furthermore, a movable ring is threadedly connected to the outer surface of the threaded rod, and two hinge ears are fixedly connected to the outer surface of the movable ring. A right-angle groove is opened in each of the two hinge ears, and a pin is fixedly connected in the right-angle groove.

[0017] The two hinged ears are respectively located on the left and right sides of the moving ring, and the right-angle slot is set at ninety degrees.

[0018] Furthermore, a connecting block is hinged to the pin on the inner wall of the right-angle groove, and a hinge seat is fixedly connected to the side of each of the two mounting brackets that are close to each other. The end of the connecting block away from the hinge ear is hinged to the hinge seat.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-6 As shown, this utility model is a transformer that is easy to install, including a transformer 1, two mounting brackets 11 are installed at the bottom of the transformer 1, and the bottom of the mounting brackets 11 has a plurality of mounting holes 111, and also includes:

[0037] Positioning mechanism 2, located below transformer 1, aligns mounting hole 111 with bolt hole. Positioning mechanism 2 includes two positioning wedges 21, each with an I-beam 211 fixedly connected to its front side; and

[0038] Adjustment mechanism 3 is located at the bottom of transformer 1 and inside I-beam block 211; wherein, mounting bracket 11 is U-shaped, mounting hole 111 penetrates the bottom of mounting bracket 11 and extends to the inner side of mounting bracket 11, and the two positioning wedges 21 are provided with inclined surfaces on the side that is close to each other, and I-beam block 211 is I-shaped.

[0039] A fixing block 22 is fixedly connected to one side of the two positioning wedges 21 that are close to each other. A positioning post 221 is fixedly connected to the top of the fixing block 22. A positioning hole 222 is opened at the bottom of the mounting bracket 11. The inner wall of the positioning hole 222 is provided with an opening. The positioning post 221 is slidably limited to the positioning hole 222. The fixing block 22 is slidably limited to the opening of the inner wall of the positioning hole 222. The positioning post 221 is conical.

[0040] Two limiting posts 31 are fixedly connected to the bottom of the transformer 1, and two limiting grooves 311 are opened on the top of the mounting bracket 11. The limiting posts 31 and the limiting grooves 311 are slidably limited. Two mounting blocks 32 are fixedly connected to the bottom of the transformer 1. Threaded rods 321 are rotatably connected inside the two mounting blocks 32. Two anti-detachment rings 322 are fixedly connected to the outer surface of the threaded rods 321. The two anti-detachment rings 322 are distributed on the front and back of the threaded rods 321 and are used to prevent the threaded rods 321 from falling out of the two mounting blocks 32.

[0041] The positioning mechanism 2 includes a connecting frame 23, with an annular groove 231 on the top of the connecting frame 23. The I-beam block 211 slides and limits the connection frame 23. When the transformer 1 deviates from the installation position, the bottom of one mounting frame 11 contacts the inclined surface of the adjacent positioning wedge 21 and is pushed away from the positioning wedge 21. When the mounting frame 11 moves down to half the height of the positioning wedge 21, the operator makes a slight adjustment back and forth so that the positioning holes 222 of the two mounting frames 11 are roughly above the positioning post 221. The mounting frame 11 continues to move down until it contacts the ground, and the transformer 1 is positioned. This positioning mechanism first makes a slight adjustment left and right when the transformer 1 is lowered to reduce the error range, and then positions it more accurately through the positioning post 221, which greatly improves the overall installation efficiency. The connecting frame 23 is annular, and the I-beam block 211 is used to prevent the positioning wedge 21 from rotating when it moves.

[0042] The outer surface of the threaded rod 321 is threaded with a movable ring 323. The outer surface of the movable ring 323 is fixedly connected with two hinge ears 324. Each of the two hinge ears 324 has a right-angle groove 325. A pin is fixedly connected in the right-angle groove 325. The two hinge ears 324 are respectively distributed on the left and right sides of the movable ring 323, and the right-angle groove 325 is set at ninety degrees.

[0043] A connecting block 326 is hinged to the pin on the inner wall of the right-angle groove 325. A hinge seat 327 is fixedly connected to the side of the two mounting brackets 11 that are close to each other. The end of the connecting block 326 away from the hinge ear 324 is hinged to the hinge seat 327. The hinge seat 327 is located at the center of the mounting bracket 11 and can transmit the power of the connecting block 326 to the mounting bracket 11.

[0044] The I-beam 211 has a threaded connection to a rotating shaft 33. A round block 331 is fixedly connected to the bottom of the rotating shaft 33, and a locking ring 332 is fixedly connected to the outer surface of the rotating shaft 33. A circular groove 333 is opened inside the I-beam 211, and the round block 331 is rotatably connected to the circular groove 333. Rotating the threaded rod 321 clockwise moves the two mounting brackets 11 closer together, while rotating it counterclockwise moves them apart. After adjustment, the connecting bracket 23 and the two positioning wedges 21 are placed in the reserved installation position. Reversing the right rotating shaft 33 moves the locking ring 332 upward and disengages it from the connecting bracket 23, allowing the positioning wedge 21 to move. After adjustment, rotating the rotating shaft 33 clockwise moves the locking ring 332 downward and the circular groove 332 moves the locking ring 331 away from the connecting bracket 23. When block 331 touches the bottom of the circular groove 333, it presses tightly against the connecting bracket 23, fixing the right positioning wedge block 21. The same applies to the left side, so that the distance between the two positioning wedge blocks 21 matches the distance between the two mounting brackets 11. This structure can adapt to different bolt hole spacings, improving the applicability of installation. The circular groove 333 extends to the outside of the I-beam block 211. The outer surface of the rotating shaft 33 is provided with threads, and the upper half of the inner wall of the circular groove 333 is provided with a threaded groove. The rotating shaft 33 is threadedly connected to the threaded groove of the upper half of the inner wall of the circular groove 333 through the threads on its outer surface. The bottom of the locking ring 332 contacts the top of the connecting bracket 23.

[0045] A specific application of this embodiment is as follows: In use, the spacing of the mounting holes 111 at the bottom of the two mounting brackets 11 is adjusted according to the spacing of the bolt holes at the reserved installation position. Specifically, rotating the threaded rod 321 clockwise causes the moving ring 323 to move backward. Since the hinge ears 324 on both sides of the moving ring 323 are hinged to the two connecting blocks 326 through pins, and the ends of the two connecting blocks 326 that are far apart from each other are respectively hinged to the hinge seats 327 on the two mounting brackets 11, when the moving ring 323 moves backward, the two mounting brackets 11 will slide on the outer surface of the two limiting posts 31 through the two limiting grooves 311 at their top. At this time, the two mounting brackets 11 move closer to each other. Rotating the threaded rod 321 counterclockwise causes the moving ring 323 to move forward and push the two mounting brackets 11 through the two connecting blocks 326. After the mounting brackets 11 are moved away from each other and the adjustment is completed, place the connecting bracket 23 and the two positioning wedges 21 together in the reserved installation position. Then, make the distance between the two positioning wedges 21 on the side closer to each other the same as the distance between the two mounting brackets 11 on the side farther from each other. Specifically, rotate the right-side rotating shaft 33 counterclockwise, and the rotating shaft 33 and the locking ring 332 will move upward. At this time, the bottom of the locking ring 332 will no longer be in close contact with the top of the connecting bracket 23, and the positioning wedges 21 can be moved to the left or right. After adjusting to the appropriate position, rotate the rotating shaft 33 clockwise. At this time, the locking ring 332 will move downward. When the round block 331 contacts the bottom of the round groove 333, the bottom of the locking ring 332 is in close contact with the top of the connecting bracket 23. At this time, the right-side positioning wedge 21 is fixed. The left-side positioning wedge 21 is adjusted in the same way.

[0046] At this point, a crane can be used to lift the transformer 1 above the installation position using the four lifting rings on the top of the transformer 1. Then, it is slowly lowered. During the lowering process, workers support the outer wall of the transformer 1 for auxiliary installation. When the transformer 1 deviates from the intended installation position, the bottom of one of its mounting brackets 11 will contact the inclined surface of the adjacent positioning wedge 21. The inclined surface of the positioning wedge 21 in contact with the mounting bracket 11 will push the transformer 1 away from itself. When the bottom of the mounting bracket 11 has moved to half the height of the positioning wedge 21, the workers observe from directly in front of the transformer 1 and make minor adjustments forward or backward to move the two positioning holes 222 at the bottom of the two mounting brackets 11 above the two positioning posts 221. The approximate position is sufficient. At this point, continue lowering the transformer 1. The positioning hole 222 will contact the conical surface at the top of the positioning post 221. The mounting bracket 11 continues to move downward. Since the position of the positioning post 221 is relatively fixed, it will guide the mounting bracket 11 to move through the conical surface until the mounting bracket 11 contacts the ground at the reserved installation position. The transformer 1 has been positioned and placed. Then, release the fixation of the two positioning wedges 21 and move the two positioning wedges 21 in the opposite direction. Since the fixing block 22 is slidably connected to the opening of the inner wall of the positioning hole 222, the fixing block 22 can smoothly leave the positioning hole 222. Then, remove the two positioning wedges 21 and the connecting bracket 23, and use bolts to connect the mounting hole 111 with the bolt hole.

[0047] Finally, it should be noted that the above embodiments are merely illustrative examples for clearly illustrating the present invention, and are not intended to limit its implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, any obvious variations or modifications derived therefrom are still within the protection scope of this invention.
