Description

Technical Field

[0001] The utility model relates to the field of transformers, in particular to a transformer with a positioning and installation function. Background Art

[0002] The transformer is like a magician, using the principle of electromagnetic induction to change the AC voltage. Simply put, when we energize one coil (primary coil) of the transformer, it will generate an alternating magnetic field on the iron core inside the transformer, and this magnetic field will cause another coil (secondary coil) to generate an induced electromotive force, thereby achieving voltage conversion. The transformer is mainly composed of the primary coil, secondary coil and iron core (magnetic core).

[0003] According to different uses, transformers can be divided into many types, such as distribution transformers, power transformers, dry-type transformers, oil-immersed transformers, etc. Each type of transformer has its specific application scenarios and functions. At the same time, since the loss of transformers in power transmission accounts for a considerable proportion, how to improve the energy efficiency of transformers and reduce power losses has always been the direction of engineers' efforts.

[0004] In general, the transformer is an indispensable part of the power system. It uses the principle of electromagnetic induction to achieve flexible voltage conversion, which provides convenience for our life and work. The transformer is usually installed and fixed with bolts and the base. During the installation process, the connection holes between the transformer and the base are more troublesome to align, and the operation is not convenient enough, which greatly affects the work efficiency. Application number: CN202022996309.4, discloses a combined transformer with positioning and installation function. By rotating the threaded column in the forward and reverse directions, the threaded column mobilizes the movable plate to move left and right through the threaded cylinder, which is used to adjust the installation hole position of the two sets of positioning frames, and then is suitable for various spacing hole trusses, with strong versatility. However, when the device is used, it is necessary to measure the spacing of the mounting holes on the mounting base in advance, and then adjust the mounting hole position of the device. In this process, first of all, the left and right movement distances of the two threaded columns to the movable plate may be inconsistent, which will cause uneven force on the base, and if the movement is found to have errors during the installation process after the movement is completed, it is necessary to lift and move the movable plate again, which is time-consuming and laborious.

[0005] Therefore, it is necessary to provide a transformer with a positioning and installation function to solve the above technical problems. Utility Model Content

[0009] The auxiliary component includes a rotating screw that is longitudinally rotatable and arranged on the inner side of the base. A push plate is provided on the circumferential side of the rotating screw that can slide back and forth along its length direction. The push plate is slidably connected to the inner side of the base, and the top of the back side of the push plate is located on the front side of the transformer body.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 ,in Figure 1 A schematic structural diagram of a preferred embodiment of a transformer with a positioning and installation function provided by the utility model; Figure 2 for Figure 1 A schematic structural diagram of a cross-sectional view of the base shown; Figure 3 for Figure 1 The schematic diagram of the structure of the cross-sectional view of the placement block shown, a transformer with positioning and installation function, comprising: a base 1, a positioning component 2 is arranged on the inner side of the base 1, and an auxiliary component 3 is arranged on the top of the base 1;

[0023] The positioning assembly 2 includes a fixed block 21 disposed inside the base 1, a slide rail 22 is disposed inside the fixed block 21 and can slide up and down, an opening for the slide rail 22 to move up and down is opened at the top of the base 1, a roller 23 is disposed at the top of the slide rail 22 and can slide forward and backward along its length direction, and a transformer body 24 is disposed outside the roller 23;

[0024] By placing the roller 23 on the transformer body 24 on the slide rail 22, after the transformer body 24 is moved to a suitable position, the mounting holes on the body match the mounting holes on the base 1, and the installation can be fixed by screwing in bolts.

[0025] The auxiliary component 3 includes a rotating screw 31 which is longitudinally rotatable and arranged on the inner side of the base 1. A push plate 32 is arranged on the peripheral side of the rotating screw 31 so as to slide back and forth along its length direction. The push plate 32 is slidably connected to the inner side of the base 1, and the top of the back side of the push plate 32 is located on the front side of the transformer body 24.

[0026] The rotating screw 31 is detachably mounted on the base 1 and can be removed and retrieved after use; the rotating screw 31 is driven by the rotation of the output end of the driving motor 33, and then the push plate 32 is driven to move backward in cooperation with the limit of the base 1, pushing the transformer body 24 to move backward.

[0027] Mounting plates 25 are provided on both sides of the transformer body 24 . Mounting holes are provided on the tops of the two mounting plates 25 . Placement blocks 26 are provided on the tops of the two mounting plates 25 . Limiting grooves 27 are provided on the inner sides of the two placement blocks 26 .

[0028] Positioning rods 28 are provided on the inner sides of the two limiting slide grooves 27 so as to be able to slide up and down along the height direction thereof, and springs 29 are provided at the tops of the two limiting slide grooves 27 and at the tops of the two positioning rods 28 respectively.

[0029] After the transformer body 24 is placed, the positioning rod 28 will retract into the placement block 26. When the auxiliary component 3 drives the transformer body 24 to move backward, once the positioning rod 28 matches the positioning hole 4, the spring 29 extends out to drive the positioning rod 28 to be stuck into the positioning hole 4, so that the entire transformer body 24 stops moving, thereby solving possible errors during alignment and making it ready for installation in one go.

[0030] The circumferential side surfaces of the two positioning rods 28 are slidably connected to the inner side of the mounting plate 25 . The two positioning rods 28 are not in the same horizontal line as the mounting holes. A positioning hole 4 for cooperating with the two positioning rods 28 is provided on the top of the base 1 .

[0031] By setting different horizontal lines, the positioning rod 28 can be placed into the mounting hole on the base 1.

[0032] The positioning assembly 2 also includes an inclined block 5 which is slidable forward and backward and is arranged inside the fixed block 21. The top of the inclined block 5 is slidably connected to the bottom of the slide rail 22. A hydraulic cylinder 6 is arranged inside the base 1 for pushing the inclined block 5 to move.

[0033] The extension of the output end of the hydraulic cylinder 6 drives the inclined block 5 to move forward and backward, and then drives the top slide rail 22 to move up and down. After the positioning rod 28 is engaged, the retracted hydraulic cylinder 6 drives the slide rail 22 downward. At this time, the bottom of the transformer body 24 abuts against the top of the base 1, which is convenient for workers to install.

[0034] A driving motor 33 for driving the rotating screw rod 31 to rotate is disposed on the inner side of the base 1 , and an output end of the driving motor 33 is fixedly connected to the rear end of the rotating screw rod 31 .

[0035] The working principle of a transformer with positioning and installation function provided by the utility model is as follows:

[0036] Step 1: When in use, by placing the roller 23 on the transformer body 24 on the slide rail 22, the rotation of the output end of the driving motor 33 drives the rotation of the rotating screw 31, and then cooperates with the limit of the base 1 to drive the push plate 32 to move backward, pushing the transformer body 24 to move backward, once the positioning rod 28 is consistent with the positioning hole 4, the spring 29 extends to drive the positioning rod 28 to be stuck in the positioning hole 4, so that the entire transformer body 24 stops moving, which solves the possible errors during alignment and makes it ready for installation at one time;

[0037] Step 2: After the positioning rod 28 is engaged, the hydraulic cylinder 6 is retracted to drive the slide rail 22 downward. At this time, the bottom of the transformer body 24 abuts against the top of the base 1 and can be fixed by screwing in the bolts.

[0038] Compared with the related art, the transformer with positioning and installation function provided by the utility model has the following beneficial effects:

[0039] By placing the roller 23 on the transformer body 24 on the slide rail 22, the rotation of the output end of the driving motor 33 drives the rotation of the rotating screw 31, and then cooperates with the base 1 to limit it and drives the push plate 32 to move backward, pushing the transformer body 24 to move backward. Once the positioning rod 28 is consistent with the positioning hole 4, the spring 29 extends out and drives the positioning rod 28 to be stuck in the positioning hole 4, so that the entire transformer body 24 stops moving. The structure is simple and practical, which solves the possible errors during alignment and avoids the trouble of lifting and installing again.
