[0027] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] like Figure 1 , Figure 4and Figure 5 As shown, a support base for a dry-type transformer in an embodiment of the utility model includes a base body 1, the base body 1 includes an upper panel 11 and a side panel 12, a dry-type transformer 5 is fixedly connected to the upper panel 11, and the base body 1 is installed on a concrete foundation 6. A threaded hole 111 is provided on the upper panel 11 of the base body 1, a lifting column 2 is provided in the threaded hole 111 on the upper panel 11, and a first external thread 22 matching the threaded hole 111 is provided on the lifting column 2, and the upper panel 11 and the lifting column 2 are threadedly connected through the threaded hole 111 and the first external thread 22.

[0029] A handle 21 is welded to the upper end of the lifting column 2, a rotating platform 23 is welded to the end of the lifting column 2 away from the handle 21, and an interface 231 is provided on the end surface of the rotating platform 23 away from the connection with the lifting column 2. The size of the interface 231 matches the docking platform 24, and the docking platform 24 can be inserted into the interface 231. When the rotating platform 24 and the docking platform 24 are in normal working state, the annular side wall and the circular bottom wall around the interface 231 cooperate to wrap the docking platform 24.

[0030] The docking platform 24 is provided with a plurality of grooves 241 , and corresponding rotating balls 242 are rotatably connected in the grooves 241 . The rotating balls 242 rotate in the grooves 241 to realize the rotatable connection between the rotating platform 23 and the docking platform 24 .

[0031] A spring 25 is fixedly connected to one end surface of the docking platform 24 away from the rotating platform 23 , one end of the spring 25 is welded to one end surface of the docking platform 24 , and the other end of the spring 25 is welded to the bearing plate 26 .

[0032] Specifically, when the seat body 1 is installed on the concrete foundation 6, the bearing plate 26 contacts the upper surface of the concrete foundation 6, and the weight of the entire seat body 1 and the dry-type transformer 5 is transferred to the concrete foundation 6 through the bearing plate. At this time, the handle 21 is turned clockwise to rotate the lifting column 2 in the threaded hole 111. Because the bearing plate 26 cannot move on the upper surface of the concrete foundation 6, the upper panel 11 moves upward under the action of the rotation of the lifting column 2. The upper panel 111 will drop when the handle 21 is rotated counterclockwise. In this way, when the upper surface of the concrete foundation 6 is not flat and does not meet the installation requirements, the horizontality of the upper panel 11 of the seat body 1 can be adjusted by rotating the handle 21 to meet the installation requirements.

[0033] Specifically, when lifting the upper panel 11, the handle 21 can be directly twisted, or other tools can be inserted into the handle 21 to rotate the handle 21, which is more labor-saving. In addition to being used to rotate the lifting column 2, the handle 21 can also be used as a fixing ring when the seat body 1 is hoisted.

[0034] Since the spring 25 is between the bearing plate 26 and the docking platform 24, when the dry-type transformer is working, the vibration generated can be buffered and eliminated by the spring 25, which is conducive to the normal operation of the dry-type transformer. At the same time, when the dry-type transformer is hoisted onto the concrete foundation 6 and lowered, the elastic effect of the spring 25 can also avoid hard contact between the dry-type transformer and the concrete foundation 6, and can also protect the dry-type transformer.

[0035] like Figures 1 to 4 As shown, a slide groove 112 is provided on the upper panel 11, and a slider 121 matching the slide groove 112 is welded on the side panel 12, and the slider 121 is slidably connected in the slide groove 112. A rubber pad 123 is bonded to the inner side wall of the side panel 12. At least two waist-shaped holes 122 are provided on the side panel 12, and the waist-shaped holes 122 pass through the side panel 12 and the rubber pad 123, and the distance between a pair of waist-shaped holes 122 is greater than the width of the concrete foundation 6.

[0036] A matching first locking rod 3 is slidably connected in the waist-shaped hole 122 on the slider 121, and a second external thread 31 is provided at both ends of the first locking rod 3, and a first nut 34 is threadedly connected to the second external thread 31. Pads 32 are welded at both ends of the first locking rod 3, and a through hole 33 is provided on the pad 32, which passes through the pad 32 and the first locking rod 3. A second locking rod 4 is slidably connected in the through hole 33 on the pad 32, and a third external thread 41 is provided at both ends of the second locking rod 4, and a second nut 42 is threadedly connected to the third external thread 41.

[0037] Specifically, the side panel 12 slides on the upper panel 11. When the side panel 12 fits the concrete foundation 6, the position of the first locking rod 3 in the waist-shaped hole 122 is adjusted at the same time, so that the first locking rod 3 fits against a side wall of the concrete foundation 6. At this time, the second nut 42 is rotated so that one end face of the second nut 42 fits against a side wall of the pad 32, so that the first locking rod 3 is fixed in the length direction of the second locking rod 4.

[0038] After the second nut 42 is tightened, the first nuts 34 at both ends of the first locking rod 3 are tightened to fix the side plate 12 at the 2 positions on the upper plate 11, so that the side plate 12 can clamp the concrete foundation 6, so that the seat body 1 is firmly installed on the concrete foundation 6. Because the side plate 12 is provided with a rubber pad 123, the elasticity of the rubber pad 123 exerts an outward force on the side plate 12, which can increase the friction between the end surface of the first nut 34 and the side plate 12, making the first nut 34 more stable on the first locking rod 3, and the rubber pad 123 can also play a certain vibration reduction role.

[0039] When in use, the dry-type transformer 5 is installed on the upper panel 11, and then the lifting rope is passed through the handle 21 to lift the base 1 onto the concrete foundation 6. At this time, the level of the upper panel 11 can be adjusted by rotating the handle 21. When the level is adjusted to meet the installation requirements, the position of the first locking rod 3 in the waist-shaped hole 122 is adjusted so that the first locking rod 3 fits the corresponding side wall of the concrete foundation 6, and then the side plate 12 is slid so that the side plate 12 fits the corresponding side wall of the concrete foundation 6, and then the first nut 34 and the second nut 42 are tightened respectively so that the position of the side plate 12 is fixed, and the position of the first locking rod in the waist-shaped hole 122 is fixed, so that the base 1 can be firmly installed on the concrete foundation 6.
