Description

Technical Field

[0001] The utility model relates to the technical field of dry-type transformers, and particularly relates to a resin casting device for transformer production. Background Art

[0002] Due to the characteristics of flame retardancy, safety, reliable operation, convenient maintenance, small volume, etc., epoxy resin cast dry-type transformers have been widely used in high-rise buildings and power stations in cities. The windings of epoxy resin cast dry-type transformers are mostly cast with epoxy resin.

[0003] Since the mold and the base are not connected separately after the dry-type transformer is cast and molded, and for the tightness of the connection between the two during use, threaded rods are mostly used for fixation. Although the threaded rods can achieve an ideal fixation effect, during casting, the cast liquid will inevitably splash out of the mold, causing some liquid to adhere to the surface of the threaded rods and solidify, which affects the use of the threaded rods, and thus the threaded rods need to be frequently replaced. Summary of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems in the related art to a certain extent.

[0005] For this purpose, the purpose of the utility model is to provide a resin casting device for transformer production, which can protect the threaded rods and reduce the replacement frequency of the threaded rods.

Detailed implementation manners

[0020] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model. On the contrary, the embodiments of the present utility model include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0021] The resin casting device for transformer production according to the embodiment of the present utility model will be described below with reference to the drawings.

[0022] As Figures 1-4 shown, the resin casting device for transformer production according to the embodiment of the present utility model includes a base 1, a mold 2, a force application plate 3 and a force application mechanism 4. Among them, the mold 2 is arranged on the base 1. The force application plate 3 is arranged on the mold 2, and the force application plate 3 is in an X shape. The force application mechanism 4 is installed on the base 1. The force application mechanism 4 includes a first fixing rod 41, a threaded rod 42, a threaded cylinder 43, a protective cylinder 44, a cleaning cylinder 45 and a connection assembly 46. Among them, the first fixing rod 41 is rotatably arranged on the base 1.

[0023] It should be noted that in the initial state, the first fixing rod 41 is not in a vertical state, that is, the first fixing rod 41 and the base 1 are in a parallel state, and thus it is impossible to drive the connection assembly 46 to be connected with the force application plate 3.

[0024] The threaded rod 42 is fixed on the first fixing rod 41. The threaded cylinder 43 is sleeved on the surface of the threaded rod 42, and the threaded cylinder 43 is threadedly connected with the threaded rod 42.

[0025] It should be noted that in the initial state, the distance between the two ends of the threaded cylinder 43 and the threaded rod 42 needs to be kept at the farthest state. After the connection assembly 46 and the force application plate 3 are connected, the distance between the two is adjusted by rotating the threaded cylinder 43. And in order to facilitate the rotation of the threaded cylinder 43, an auxiliary rotation structure similar to a nut needs to be provided on the threaded cylinder 43.

[0026] The protective cylinder 44 is fixed on the threaded cylinder 43. The cleaning cylinder 45 is fixedly installed on the protective cylinder 44, and the cleaning cylinder 45 is frustum-shaped.

[0027] It can be understood that since the top of the frustum-shaped cleaning cylinder 45 is larger than the bottom, similar to an umbrella, the frustum-shaped cleaning cylinder 45 can block part of the splashed casting liquid during casting, reducing the amount of casting liquid attached to the surface of the first fixing rod 41.

[0028] The force application mechanism 4 is fixed on the threaded cylinder 43.

[0029] Specifically, during the actual operation, the relevant personnel need to use the force - applying plate 3 to extrude the mold 2, so that the mold 2 can be tightly connected to the base 1 to prevent the pouring liquid from flowing out during pouring.

[0030] Based on this, by setting the force - applying mechanism 4, during use, first place the force - applying plate 3 above the mold 2, then rotate the first fixing rod 41, so that the first fixing rod 41 drives the connecting component 46 to be connected to the force - applying plate 3, and then rotate the threaded cylinder 43, so that the threaded cylinder 43 moves downward under the action of the threaded rod 42, achieving the purpose of pulling the force - applying plate 3, making the force - applying plate 3 extrude the mold 2 and the base 1 to be tightly connected. And during the use of the threaded rod 42, the protective cylinder 44 protects the threaded rod 42. At the same time, when the threaded cylinder 43 moves downward, it will drive the protective cylinder 44 to move downward, and then the downward - moving protective cylinder 44 drives the cleaning cylinder 45 to clean the foreign matters on the surface of the first fixing rod 41, avoiding the foreign matters on the surface of the first fixing rod 41 from affecting the downward movement of the protective cylinder 44.

[0031] By setting the threaded cylinder 43 above the threaded rod 42 and sleeving the protective cylinder 44 on the surface of the threaded rod 42, the purpose of protecting the threaded rod 42 is achieved. It can avoid the pouring liquid from splashing onto the surface of the threaded rod 42 when pouring the transformer, reduce the influence on the threaded rod 42, and reduce the replacement frequency of the threaded rod 42.

[0032] In an embodiment of the present utility model, as Figure 4 shown, the inner diameter of the protective cylinder 44 is the same as the outer diameter of the first fixing rod 41, and the protective cylinder 44 is slidably arranged on the surface of the first fixing rod 41.

[0033] In an embodiment of the present utility model, as Figure 4 shown, the outer diameter of the top of the cleaning cylinder 45 is larger than the outer diameter of the protective cylinder 44.

[0034] In an embodiment of the present utility model, as Figure 3 and Figure 4 shown, the connecting component 46 of the force - applying machine includes an installation cylinder 461, a pulling spring 462, a pulling rod 463, a connecting block 464, two rotating rods 465 and an installation groove 466. Among them, the installation cylinder 461 is installed on the first fixing rod 41. The pulling spring 462 is arranged inside the installation cylinder 461, and the pulling rod 463 is fixed to one end of the pulling spring 462.

[0035] In an embodiment of the present utility model, in order to facilitate observing the length of the pulling rod 463 extending out of the installation cylinder 461, scales can be engraved on the surface of the pulling rod 463, and thus the length of the pulling rod 463 extending out of the installation cylinder 461 can be judged more intuitively.

[0036] The connecting block 464 is fixed on the pulling rod 463, and the two rotating rods 465 are distributed relatively on the connecting block 464.

[0037] It can be understood that the two rotating rods 465 are rotatably arranged on both sides of the connecting block 464. The purpose of the rotatable arrangement is to reduce the friction between the rotating rod 465 and the force-applying plate 3, which is convenient for subsequently removing the rotating rod 465 from the surface of the force-applying plate 3.

[0038] The installation groove 466 is opened on the force-applying plate 3.

[0039] In an embodiment of the present utility model, as Figure 3 shown, the width of the installation groove 466 is the same as the length of the connecting block 464.

[0040] Specifically, during the actual operation process, the rotation of the first fixed rod 41 drives the threaded rod 42, the threaded barrel 43, and the installation barrel 461 to rotate. When the installation barrel 461 drives the connecting block 464 and the rotating rod 465 to rotate to one side of the installation groove 466, by pulling the rotating rod 465 upward, a part of the pulling rod 463 is moved out of the interior of the installation barrel 461. Then, the first fixed rod 41 can be rotated again to drive the rotating rod 465 above the force-applying plate 3, completing the connection between the connection assembly 46 and the force-applying plate 3.

[0041] After the connection, the threaded barrel 43 is rotated. The downward movement of the threaded barrel 43 will drive the installation barrel 461 to move downward. Furthermore, the pulling spring 462 can be pulled by the installation barrel 461, so that the pulling spring 462 is in a stretched state. Then, the force-applying plate 3 is pulled by the pulling force of the pulling spring 462. Therefore, the downward movement distance of the threaded barrel 43 is the same as the downward movement distance of the installation barrel 461, the downward movement distance of the installation barrel 461 is the same as the distance that the pulling rod 463 moves out of the installation barrel 461, and the distance that the pulling rod 463 moves out is related to the stretching length of the pulling spring 462. Thus, the force applied to the force-applying plate 3 can be judged by the length that the pulling rod 463 extends out of the interior of the installation barrel 461, solving the problem that the existing pouring device cannot observe the extrusion force on the mold 2.

[0042] In summary, for the transformer production resin pouring device in the embodiment of the present utility model, by arranging the threaded barrel above the threaded rod and sleeving a protective barrel on the surface of the threaded rod, the purpose of protecting the threaded rod is achieved. It can avoid the pouring liquid splashing onto the surface of the threaded rod when pouring the transformer, reducing the influence on the threaded rod and lowering the replacement frequency of the threaded rod.
