Description

Technical Field

[0001] This utility model relates to the field of transformer core maintenance technology, specifically a support and positioning device for transformer core maintenance in power plants. Background Technology

[0002] The transformer core is the core component that forms the magnetic circuit in a transformer. It is mainly made of high-permeability materials (such as silicon steel sheets or amorphous alloys) and its function is to efficiently transmit magnetic flux and realize voltage conversion.

[0003] During transformer maintenance, the transformer cores are typically stacked, then tightened, fixed, and fitted with yokes and coils. Because the cores are positioned visually during stacking, tilting or unevenness can occur. After stacking, a positioning device is needed to correct the alignment, resulting in low installation efficiency. After positioning, clamping blocks are installed to tighten the cores, but manual operation is time-consuming and labor-intensive, failing to meet requirements. Therefore, we propose a support and positioning device for power plant transformer core maintenance to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a support and positioning device for the maintenance of transformer cores in power plants, so as to solve the problem mentioned in the background art that when transformer cores are stacked, relying on human eyes for positioning is prone to tilting or unevenness, resulting in low efficiency of transformer core installation and maintenance. After positioning, clamping blocks are installed on the transformer core to clamp the transformer core, but manual operation is time-consuming and labor-intensive and cannot meet the requirements of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support and positioning device for overhauling the core of a power plant transformer, comprising a transformer, wherein a support and positioning assembly is provided on the outside of the transformer, and the support and positioning assembly includes a connecting frame, a bidirectional screw, and an adjusting ring; The connecting frame is located on the outside of the transformer, the bidirectional screw is located inside the connecting frame, an adjusting ring is provided on the outside of the bidirectional screw, and positioning frames are provided at both ends of the bidirectional screw.

[0006] Preferably, the positioning frame includes a positioning ring and a support rod. The two ends of the bidirectional screw are threaded with positioning rings. The positioning rings are I-shaped and have support rods on both sides. Fixed shafts are installed inside the positioning rings and support rods. The two sets of support rods are L-shaped and have positioning plates fixedly connected to their outer ends.

[0007] Preferably, the connecting frame is internally rotatably connected to a bidirectional screw, the adjusting ring is fixedly installed at the center position of the bidirectional screw, and the two sets of positioning frames are threadedly connected to the bidirectional screw.

[0008] Preferably, the bottom of the fixed shaft is fixedly connected to the inner wall of the positioning ring, and an adjustment knob is threadedly connected to the outer side of the fixed shaft.

[0009] Preferably, a handle is fixedly connected to the outer side of the connecting frame, and a groove is formed on the inner wall of the handle.

[0010] Preferably, the surface of the bidirectional screw is provided with scale lines, and limit blocks are fixedly connected to both ends of the bidirectional screw.

[0011] Preferably, a protective pad is fixedly connected to the inner wall of the positioning plate. The protective pad is made of rubber, and the surface of the rubber is provided with a wavy anti-slip texture with a depth of two millimeters.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model uses a support and positioning component to position the transformer core during maintenance and installation. The positioning frame is placed on the surface of the core, and the bidirectional screw is rotated to drive the adjusting ring to rotate within the connecting frame, causing the positioning frames at both ends to move relative to each other. This adjusts the locking force of the transformer core, achieving the purpose of support and positioning without the need for manual tightening. This not only saves manpower and resources but also improves the installation efficiency of the transformer core, making it highly practical.

[0013] This utility model, through the setting of the positioning frame, allows for adjustment of the tightness of the adjustable knob according to the shape characteristics of the transformer, thereby adjusting the angle of the support rod and fitting it to the transformer surface to match the transformer. Then, the angle of the support rod is fixed and locked, improving the applicability of the device and preventing the transformer core from tilting or becoming uneven. Attached Figure Description

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides an embodiment of a support and positioning device for the maintenance of transformer cores in power plants, including a transformer 1. The transformer 1 has an iron core on its outer side. A corresponding number of support and positioning components 2 are installed on the outer side of the transformer 1 according to its size. The support and positioning components 2 include a connecting frame 201, a bidirectional screw 202, and an adjusting ring 203. The connecting frame 201 is located on the outer side of the transformer 1, the bidirectional screw 202 is located inside the connecting frame 201, the adjusting ring 203 is located on the outer side of the bidirectional screw 202, and positioning frames 3 are located at both ends of the bidirectional screw 202. This device, through the setting of the support positioning component 2 and the positioning frame 3, solves the problem that when transformer cores are stacked, relying on human eyes for positioning can easily lead to tilting or unevenness, resulting in low efficiency in the installation and maintenance of transformer cores. After positioning, clamping blocks are installed on the transformer cores to clamp them. Manual operation is time-consuming and laborious, and cannot meet the requirements of use.

[0019] Furthermore, the positioning frame 3 includes a positioning ring 301 and support rods 303. The two ends of the bidirectional screw 202 are threadedly connected to the positioning ring 301. The positioning ring 301 is I-shaped, and support rods 303 are provided on both sides. A fixed shaft 302 is installed inside the positioning ring 301 and the support rods 303. The two sets of support rods 303 are L-shaped, and positioning plates 304 are fixedly connected to their outer ends. Figure 3 As shown, this structure is used to fit the positioning plate 304 at the support rod 303 with the iron core on the outside of the transformer 1, so as to facilitate the support and positioning of the iron core.

[0020] Furthermore, a bidirectional screw 202 is rotatably connected inside the connecting frame 201, and an adjusting ring 203 is fixedly installed at the center position of the bidirectional screw 202. Two sets of positioning frames 3 are threadedly connected to the bidirectional screw 202. Figure 2 As shown, this structure is used to rotate the adjusting ring 203 to drive the bidirectional screw 202 to rotate within the connecting frame 201, so that the positioning frames 3 at both ends move relative to each other through the threads, thereby locking and positioning the core of the transformer 1.

[0021] Furthermore, the bottom of the fixed shaft 302 is fixedly connected to one inner wall of the positioning ring 301, and the other end passes through the surface of the positioning ring 301. An adjusting knob 305 is threaded onto the outer side of the fixed shaft 302, and a support rod 303 is sleeved on the outer side of the fixed shaft 302 and rotatably connected to the positioning ring 301. Figure 3 As shown, this structure is used to adjust the tightness of the support rod 303 by rotating the adjustment knob 305, so that the support rod 303 can rotate. According to the shape characteristics of the transformer 1, the angle of the support rod 303 is adjusted by rotating it, so that the support rod 303 fits against the surface of the transformer 1 core, thereby increasing the contact area between the positioning plate 304 and the transformer 1 core and improving the fixing effect.

[0022] Furthermore, a handle 4 is fixedly connected to the outer side of the connecting bracket 201, and a groove is formed on the inner wall of the handle 4. For example... Figure 2 As shown, this structure is designed to make it easy for users to pick up the item through the handle 4, while the design of the inner wall groove prevents it from slipping out of the hand when picking it up.

[0023] Furthermore, the surface of the bidirectional screw 202 is provided with scale lines 5, and limit blocks 6 are fixedly connected to both ends of the bidirectional screw 202 to facilitate the positioning frame 3 moving outward and disengaging from the surface of the bidirectional screw 202. Figure 2 As shown, this structure is used to facilitate observation of the distance moved when the positioning frame 3 moves relative to the loosening of the scale line 5, thereby enabling accurate positioning.

[0024] Furthermore, a protective pad 306 is fixedly connected to the inner wall of the positioning plate 304. The protective pad 306 is made of rubber, and the surface of the rubber is provided with a wavy anti-slip texture with a depth of two millimeters to avoid wear on the transformer 1 core during tightening. Figure 3 As shown, the structure utilizes the cushioning and anti-slip properties of the rubber at the protective pad 306. Its anti-slip texture enhances its anti-slip effect, and the two-millimeter depth ensures that the anti-slip texture still provides an anti-slip effect even after a certain degree of wear.

[0025] Working principle: When using, such as Figure 1 and Figure 2As shown, when the core of transformer 1 needs to be inspected and installed, hold handle 4 and place the support positioning component 2 in the corresponding position, as shown. Figure 2 and Figure 3 As shown, the protective pad 306 at the positioning plate 304 is brought into contact with the iron core on the outside of the transformer 1 to facilitate the support and positioning of the iron core. Then, the adjusting ring 203 is rotated, which drives the bidirectional screw 202 to rotate within the connecting frame 201. This causes the positioning rings 301 at both ends to move relative to each other through the threads at the bidirectional screw 202, locking and positioning the iron core of the transformer 1. When using transformers of different shapes, the tension of the support rod 303 is adjusted by rotating the adjusting knob 305, allowing the support rod 303 to rotate. According to the shape characteristics of the transformer 1, the angle of the support rod 303 is adjusted by rotating it, and then the adjusting knob 305 is rotated in the opposite direction to lock it, so that the support rod 303 is in contact with the surface of the iron core of the transformer 1, increasing the contact area between the positioning plate 304 and the iron core of the transformer 1. The adjusting ring 203 is then rotated, and the above operation is repeated. The above is the complete working principle of this utility model.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
