A dry-type transformer that is easy to install

Abstract

This utility model discloses a dry-type transformer that is easy to install, including a transformer body. Multiple crossbeams are horizontally fixed to the bottom of the transformer body. This utility model relates to the field of dry-type transformer technology. This easy-to-install dry-type transformer utilizes multiple sliding structures. Each sliding structure includes a threaded tube with a threaded column vertically threaded inside. The bottom end of the threaded column has movable balls. After the device is hoisted into the equipment box, the multiple movable balls contact the lower surface of the equipment box, maintaining a relative sliding state between the device and the equipment box. This allows workers to more easily adjust the position of the device. After adjustment, the threaded column can be rotated to retract the movable balls into the threaded tube. At this point, the extension plates at the bottom of the multiple crossbeams contact the lower surface of the equipment box, allowing bolts to be used to fix the transformer body, thus improving the efficiency of the installation operation.

Description

Technical Field

[0001] This utility model relates to the field of dry-type transformer technology, specifically a dry-type transformer that is easy to install. Background Technology

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, a dry-type transformer is a transformer whose core and windings are not immersed in insulating oil.

[0003] When dry-type transformers are actually installed, they are usually protected by an equipment box. Because dry-type transformers are heavy, they need to be hoisted into the equipment box by hoisting equipment. However, the hoisting equipment can only hoist and place the dry-type transformer in a general position inside the equipment box. Afterwards, its position needs to be precisely adjusted before the final fixing work can be carried out. However, due to the weight of the dry-type transformer, it is difficult to adjust its position manually, which is quite inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dry-type transformer that is easy to install, solving the problem that the heavy weight of dry-type transformers makes it difficult to adjust their position manually, which is quite inconvenient.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a dry-type transformer that is easy to install, comprising a transformer body, wherein multiple cross frames are horizontally fixedly connected to the bottom end of the transformer body, and extension plates are fixedly connected to both sides of the bottom end of the multiple cross frames, and sliding structures are provided on the multiple extension plates.

[0006] All of the sliding structures have the same structure. One of the sliding structures includes a through hole that is vertically opened on the upper surface of the extension plate. A threaded tube with the same inner diameter as the through hole is fixedly connected to the upper surface of the extension plate. A threaded column is vertically threaded inside the threaded tube. A ball hole is opened at the bottom end of the threaded column. A movable ball is provided inside the ball hole.

[0007] Furthermore, each of the threaded posts is fixedly connected to a hexagonal nut at its top.

[0008] Furthermore, multiple reinforcing ribs are fixedly connected between the outer surfaces of the multiple threaded tubes and the upper surface of the extension plate.

[0009] Furthermore, multiple reinforcing plates are fixedly connected between the outer surfaces of the multiple crossbeams and the upper surfaces of the extension plates thereon.

[0010] Furthermore, mounting holes are vertically drilled through the upper surfaces of both ends of the multiple crossbeams.

[0011] Furthermore, both ends of the two crossbeams on the upper part of the transformer body are provided with holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-install dry-type transformer, by setting multiple sliding structures, includes a threaded tube with a threaded column connected vertically inside. The bottom end of the threaded column is provided with a movable ball. After the device is hoisted into the equipment box, the multiple movable balls contact the lower surface of the equipment box, so that the device and the equipment box maintain a relative sliding state. The operator can more easily adjust the position of the device. After the position is adjusted, the multiple threaded columns can be rotated to make the movable balls retract into the threaded tube. At this time, the extension plates at the bottom of the multiple crossbeams contact the lower surface of the equipment box, and the transformer body can be fixed with bolts, which improves the efficiency of the installation operation.

[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 a technical solution: a dry-type transformer that is easy to install, including a transformer body 1, a plurality of cross frames 2 are horizontally fixedly connected to the bottom end of the transformer body 1, and extension plates 3 are fixedly connected to both sides of the bottom end of the plurality of cross frames 2, and a sliding structure is provided on the plurality of extension plates 3.

[0019] The structures of multiple sliding structures are identical. One of the sliding structures includes a through hole that is vertically opened on the upper surface of the extension plate 3. A threaded tube 4 with the same inner diameter as the through hole is fixedly connected to the upper surface of the extension plate 3. A threaded column 5 is vertically threaded inside the threaded tube 4. A ball hole 7 is opened at the bottom end of the threaded column 5. A movable ball 8 is installed inside the ball hole 7.

[0020] The sliding structure in this device includes a threaded tube 4, with a threaded post 5 vertically threaded inside. The bottom end of the threaded post 5 is equipped with movable balls 8. After the device is hoisted into the equipment box, the multiple movable balls 8 contact the lower surface of the equipment box, allowing the device to slide relative to the equipment box. This makes it easier for workers to adjust the position of the device. After the position is adjusted, the multiple threaded posts 5 can be rotated to retract the movable balls 8 into the threaded tube 4. At this time, the extension plates 3 at the bottom of the multiple crossbeams 2 contact the lower surface of the equipment box, and the transformer body can be fixed with bolts, improving the efficiency of the installation work.

[0021] The top of each of the multiple threaded posts 5 is fixedly connected with a hexagonal nut 6.

[0022] When it is necessary to rotate the threaded column 5, a wrench can be used to clamp the hexagonal nut 6 and then rotate the threaded column 5. During the rotation of the threaded column 5, it will move along the height direction of the threaded tube 4 under the action of the thread inside the threaded tube 4, thereby driving the movable ball 8 to move upward and be taken into the interior of the threaded tube 4.

[0023] Multiple reinforcing ribs 9 are fixedly connected between the outer surface of the multiple threaded pipes 4 and the upper surface of the extension plate 3.

[0024] The reinforcing rib 9 can improve the structural strength of the connection between the threaded tube 4 and the extension plate 3.

[0025] Multiple reinforcing plates are fixedly connected between the outer surfaces of the multiple crossbars 2 and the upper surfaces of the extension plates 3 thereon.

[0026] The reinforcing plate can improve the structural strength between the extension plate 3 and the cross frame 2, thereby improving the overall stability of the device.

[0027] Multiple crossbars 2 have vertically penetrating mounting holes 10 on their upper surfaces at both ends.

[0028] Mounting hole 10 is used to fix the entire device. When fixing the device, bolts are passed through mounting hole 10 and tightened to fix the device inside the equipment box.

[0029] Both ends of the two crossbeams on the upper part of the transformer body 1 are provided with holes 11.

[0030] The hole 11 facilitates the installation of the device onto the hoisting rope and also limits the rope to prevent its movement from affecting the stability during hoisting.

[0031] During operation, the sliding structure of the device includes a threaded tube 4, with a threaded column 5 vertically threaded inside. The bottom end of the threaded column 5 is equipped with movable balls 8. After the device is hoisted into the equipment box, the multiple movable balls 8 contact the lower surface of the equipment box, allowing the device to slide relative to the equipment box. This makes it easier for the operator to adjust the position of the device. After the position is adjusted, the multiple threaded columns 5 can be rotated to retract the movable balls 8 into the threaded tube 4. At this time, the extension plates 3 at the bottom of the multiple crossbeams 2 contact the lower surface of the equipment box, and the transformer body can be fixed with bolts, improving the efficiency of the installation work.
