Description

Technical Field

[0001] This utility model belongs to the field of dry-type transformer technology, and specifically relates to a base support mechanism for a dry-type transformer. Background Technology

[0002] A dry-type transformer is a power transformer that does not use liquids (such as insulating oil) as a cooling and insulating medium. Its core and windings are directly exposed to the air or encapsulated in solid insulating materials. Dry-type transformers require a base support mechanism for support.

[0003] The existing base structure of dry-type transformers is usually a steel frame welded from channel steel. In the production and use of this steel frame, a protective frame made of welded channel steel is often needed to be installed on the steel frame to protect the dry-type transformer. However, in actual use, different models and specifications of dry-type transformers result in different sizes of transformers. This means that channel steel of different lengths needs to be welded to form steel frames and protective frames of different specifications. The process of selecting channel steel of different lengths and welding them together adds a certain workload to the installers and is not conducive to their use. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a base support mechanism for a dry-type transformer. By adjusting the horizontal position of the first and second protective frames and then adjusting the length of their extensions, the first and second protective frames can be adapted to the model and specifications of the dry-type transformer for efficient limiting protection.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a base support mechanism for a dry-type transformer, including a base, a plurality of guide grooves are provided on the base, a slide rod is slidably arranged inside each guide groove, a guide rail is provided between two slide rods on the same side, a symmetrically distributed slide table is slidably arranged inside each guide rail, a fixed seat is provided on the upper surface of each slide table, a plurality of slide cylinders I are provided on each fixed seat, a protective frame I is slidably arranged between slide cylinders I, a plurality of slide cylinders II are provided on each fixed seat, and a protective frame II is slidably arranged between slide cylinders II; a plurality of fixed plates are provided on the outer side of the base, and a fixed hole is provided on each fixed plate.

[0006] As a further improvement of this utility model, a driving mechanism is provided on the base, which is used to adjust the spacing between the guide rails. The driving mechanism includes a support 1 symmetrically arranged inside the base, each support 1 having a bidirectional screw rotatably mounted on it. A sliding rod is threadedly connected to the adjacent bidirectional screw. A bevel gear 1 is fixedly sleeved in the middle of each bidirectional screw. A rotating rod is rotatably mounted on the upper side inside the base. A bevel gear 2 symmetrically distributed is fixedly sleeved on the outer arc surface of the rotating rod. Each bevel gear 2 is meshed with the adjacent bevel gear 1. A worm gear is fixedly sleeved in the middle of the outer arc surface of the rotating rod. A support 2 is provided inside the base, and a worm is rotatably mounted in the middle of the inner part of the support 2. The worm is meshed with the worm gear. A handwheel is provided on the outer side of the base, and the handwheel is fixed to the worm through a coupling via a linkage rod.

[0007] As a further improvement of this utility model, each guide rail is provided with multiple positioning holes, and the slide table and the adjacent guide rail are connected and fixed by positioning bolts inserted in the positioning holes.

[0008] As a further improvement of this utility model, each protective frame 1 is provided with multiple limiting holes 1, and the upper and lower sliding cylinders 1 are connected and fixed to the protective frame 1 by limiting bolts 1 inserted in the limiting holes 1. Each protective frame 2 is provided with multiple limiting holes 2, and the upper and lower sliding cylinders 2 are connected and fixed to the protective frame 2 by limiting bolts 2 inserted in the limiting holes 2.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, rotating the handwheel causes the worm gear connected to it to rotate via the linkage rod, adjusting the distance between the front and rear protective frames, so that the front and rear protective frames are close to the dry-type transformer for limit protection.

[0011] Secondly, sliding the fixed seats on the left and right sides causes the fixed seats to slide against the guide rail, which in turn causes the guide rail to move the protective frames on the left and right sides closer to the dry-type transformer for limit protection.

[0012] Third, after inserting the limiting bolt one into the limiting hole one between the slide cylinder one and the protective frame one, the nut is tightened by an external tool to fix the slide cylinder one and the protective frame one. After inserting the limiting bolt two into the limiting hole two between the slide cylinder two and the protective frame two, the nut is tightened by an external tool to fix the protective frame two and the slide cylinder two. The length of the extended protective frame one and the protective frame two is adjusted.

[0013] Fourth, by adjusting the horizontal position of the first and second protective frames and then adjusting the length of the extended protective frames, the first and second protective frames can be adapted to the model and specifications of the dry-type transformer to provide efficient limiting protection.

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 2 , 4 As shown, the system includes a base 101, on which multiple guide grooves 103 are provided. Each guide groove 103 has a sliding rod 104 slidably disposed inside. A guide rail 105 is provided between two sliding rods 104 on the same side. Each guide rail 105 has symmetrically distributed sliding tables 106 slidably disposed inside. Each sliding table 106 has a fixed seat 107 on its upper surface. Each fixed seat 107 has multiple first sliding cylinders 108 slidably disposed between the first sliding cylinders 108. Each fixed seat 107 has multiple second sliding cylinders 111 slidably disposed between the second sliding cylinders 111. A second protective frame 112 is slidably disposed between the second sliding cylinders 111. A driving mechanism is provided on the base 101 to adjust the spacing between the guide rails 105.

[0022] like Figure 2 ,3 As shown, the drive mechanism includes supports 201 symmetrically arranged inside the base 101. Each support 201 is rotatably provided with a bidirectional screw 202. The slide rod 104 is threadedly connected to the adjacent bidirectional screw 202. A bevel gear 203 is fixedly sleeved in the middle of each bidirectional screw 202. A rotating rod 204 is rotatably arranged on the upper side inside the base 101. A bevel gear 204 is fixedly sleeved on the outer arc surface of the rotating rod 204. Each bevel gear 204 is meshed with the adjacent bevel gear 203.

[0023] like Figure 3 , 4 As shown, a worm gear 205 is fixedly sleeved in the middle of the outer arc surface of the rotating rod 204. A support 206 is provided inside the base 101. A worm 207 is rotatably installed in the middle of the support 206. The worm 207 is meshed with the worm gear 205. A handwheel 208 is provided on the outside of the base 101. The handwheel 208 is fixed to the worm 207 through a coupling via a linkage rod.

[0024] like Figure 1 , 2 As shown, each guide rail 105 has multiple positioning holes 114, and the slide table 106 is connected and fixed to the adjacent guide rail 105 by positioning bolts inserted in the positioning holes 114; each protective frame 109 has multiple limiting holes 110, and the upper and lower sliding cylinders 108 are connected and fixed to the protective frame 109 by limiting bolts inserted in the limiting holes 110; each protective frame 2 112 has multiple limiting holes 2 113, and the upper and lower sliding cylinders 2 111 are connected and fixed to the protective frame 2 112 by limiting bolts inserted in the limiting holes 2 113.

[0025] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a plurality of fixing plates 102 are provided on the outer side of the base 101, and each fixing plate 102 has a fixing hole.

[0026] When in use, place the dry-type transformer to be installed in the middle of the upper surface of the base 101, and use external tools to tighten the bolts to connect and fix the dry-type transformer to the base 101.

[0027] Then, by rotating the handwheel 208, the handwheel 208 drives the worm gear 207 connected to it to rotate via the linkage rod. The meshing relationship between the worm gear 207 and the worm wheel 205 drives the rotating rod 204 where the worm wheel 205 is located to rotate, which in turn drives the bevel gears 202 set at both ends of the rotating rod 204 to rotate. The meshing relationship between the bevel gear 202 and the adjacent bevel gear 103 drives the bidirectional screw 202 where the bevel gear 103 is located to rotate. During the rotation of the bidirectional screw 202, the threaded relationship between the bidirectional screw 202 and the slide rod 104 drives the slide rods 104 on both sides to move towards each other or away from each other, which drives the guide rails 105 on both sides to move towards each other or away from each other, adjusting the distance between the protective frames 109 on both sides, so that the protective frames 109 on both sides are close to the dry-type transformer for limit protection.

[0028] Then, the personnel slide the fixed seats 107 on the left and right sides to make the fixed seats 107 slide with the guide rail 105, thereby causing the guide rail 105 to drive the protective frames 112 on the left and right sides to approach the dry-type transformer for limit protection; then, the personnel insert the positioning bolts into the positioning holes 114 between the slide table 106 and the guide rail 105, and then use external tools to tighten the nuts to fix the slide table 106 and the guide rail 105.

[0029] Personnel slide the left and right protective frames 109 to make them slide against the slide cylinder 108, extending the protective frame 109 to the appropriate length to protect the dry-type transformer. Then, personnel insert the limiting bolt 1 into the limiting hole 110 between the slide cylinder 108 and the protective frame 109, and then use an external tool to tighten the nut to fix the slide cylinder 108 and the protective frame 109. Slide the front and rear protective frames 112 to make them slide against the slide cylinder 111, extending the protective frame 112 to the appropriate length to protect the dry-type transformer. Then, personnel insert the limiting bolt 2 into the limiting hole 113 between the slide cylinder 111 and the protective frame 112, and then use an external tool to tighten the nut to fix the protective frame 112 and the slide cylinder 111.

[0030] By adjusting the horizontal position of the first protective frame 109 and the second protective frame 112, and then adjusting the extension length of the first protective frame 109 and the second protective frame 112, the first protective frame 109 and the second protective frame 112 can be adapted to the model and specifications of the dry-type transformer to provide efficient limiting protection.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
