Description

Technical Field

[0001] This utility model relates to the field of dry-type transformer technology, specifically a suspended anti-collision dry-type transformer. Background Technology

[0002] A dry-type transformer is a device that converts electrical energy from one voltage level to another. It does not require oil for cooling; instead, it uses special insulating materials to isolate current and prevent electric arcing. These transformers are widely used in both indoor and outdoor power systems.

[0003] In the prior art, the authorized patent with publication number CN219105861U discloses a suspended anti-collision dry-type transformer, including a suspension device base, a support column installed at the upper end of the suspension device base, a lifting device installed on the support column, a dry-type transformer protection box installed on the lifting device via a fixing plate, a dry-type transformer installed inside the dry-type transformer protection box, a buffer device installed at the lower end of the dry-type transformer and the lower end of the dry-type transformer protection box, and anti-collision devices installed on both walls of the dry-type transformer protection box that contact the dry-type transformer. This utility model, by placing the dry-type transformer inside the dry-type transformer protection box, not only provides anti-collision protection, but also effectively dissipates heat from the dry-type transformer through a cooling fan installed at the top of the dry-type transformer protection box. The suspension is achieved by raising the dry-type transformer protection box and the dry-type transformer using a lifting device, which is safer than traditional steel cable slinging and prevents swaying in strong winds.

[0004] However, the above technical solutions still have the following shortcomings in actual use: When the above devices are in use, the lifting plate lacks an auxiliary support structure, and the weight of the dry-type transformer is entirely applied to the threaded sleeve. After long-term use, the threads of the threaded sleeve and the threaded rod will deform due to gravity, causing the device to be unable to lift and lower, thus affecting its service life. In this regard, we propose a suspended anti-collision dry-type transformer to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a suspended anti-collision dry-type transformer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suspended anti-collision dry-type transformer, comprising:

[0007] The base has two support columns fixedly installed on its top wall. A top plate is welded to the top of each support column. A lifting seat is installed on each support column, and a lifting plate is fixedly installed on the lifting seat. A protective box is fixedly installed on the top wall of the lifting plate, and a dry-type transformer is installed inside the protective box. Two pairs of support legs are provided on the bottom wall of the lifting plate, symmetrically arranged left and right. A connecting rod is fixedly welded between each pair of support legs. A double-headed motor is fixedly installed in the middle of the bottom wall of the lifting plate. Two screws are driven and connected to the double-headed motor. The threads on the two screws are in opposite directions. Each screw has a linkage rod, and the tops of the two linkage rods are respectively fixedly welded to the two connecting rods.

[0008] Preferably, the linkage rod has a sliding groove, and a slider is slidably connected in the sliding groove. The slider is threadedly connected to the screw rod through a threaded hole.

[0009] Preferably, a limiting groove is provided on the linkage rod, a limiting block is fixedly welded on the slider, and the limiting block is slidably connected in the limiting groove.

[0010] Preferably, the top wall of the base is provided with two pairs of guide grooves, and the bottom ends of the two pairs of support legs are slidably connected in the two pairs of guide grooves respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In use, when the lifting plate raises the dry-type transformer, the two pairs of support legs can provide auxiliary support to the lifting plate, preventing the weight of the dry-type transformer from acting entirely on the threaded sleeve. When it is necessary to lower the lifting plate, the dual-head motor can be started to drive the two screws to rotate in the forward direction, causing the two sliders to move outward on the corresponding screws, thereby driving the two pairs of support legs to move outward. When the two pairs of support legs move out of the lifting plate, the dual-head motor stops. At this time, the lifting plate can drive the dual-head motor and the two screws to move downward, making it convenient for the dry-type transformer to be lowered for maintenance or repair.

[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 suspended anti-collision dry-type transformer, comprising:

[0019] The base 1 has two support columns 2 fixedly installed on its top wall. A top plate 3 is fixedly welded to the top of the two support columns 2. A lifting seat 4 is installed on the two support columns 2. A lifting plate 5 is fixedly installed on the lifting seat 4. A protective box 6 is fixedly installed on the top wall of the lifting plate 5. A dry-type transformer is installed inside the protective box 6. Two pairs of support legs 7 are provided on the bottom wall of the lifting plate 5. The two pairs of support legs 7 are arranged symmetrically on the left and right. A connecting rod 8 is fixedly welded between each pair of support legs 7. A double-headed motor 9 is fixedly installed in the middle of the bottom wall of the lifting plate 5. Two screws 10 are connected to the double-headed motor 9. The threads on the two screws 10 are opposite in direction. A linkage rod 11 is provided on each of the two screws 10. The tops of the two linkage rods 11 are fixedly welded to the two connecting rods 8 respectively.

[0020] The linkage rod 11 is provided with a sliding groove 12, and a slider 13 is slidably connected in the sliding groove 12. The slider 13 is threadedly connected to the screw rod 10 through a threaded hole. Through the sliding cooperation between the slider 13 and the sliding groove 12, the screw rod 10 can be raised and lowered on the linkage rod 11.

[0021] A limiting groove 14 is provided on the linkage rod 11, and a limiting block 15 is fixedly welded on the slider 13. The limiting block 15 is slidably connected in the limiting groove 14. Through the sliding cooperation between the limiting block 15 and the limiting groove 14, the linkage rod 11 can be moved when the slider 13 moves left and right.

[0022] Two pairs of guide grooves 16 are provided on the top wall of the base 1. The bottom ends of the two pairs of support legs 7 are slidably connected in the two pairs of guide grooves 16. The guide grooves 16 are used to guide the support legs 7 when they move left and right.

[0023] Working principle: When this utility model is in use, after the lifting plate 5 lifts the dry-type transformer, the two pairs of support legs 7 provide auxiliary support for the lifting plate 5, preventing the weight of the dry-type transformer from acting entirely on the threaded sleeve. When it is necessary to lower the lifting plate 5, the double-headed motor 9 can be started, driving the two screws 10 to rotate in the forward direction, causing the two sliders 13 to move outward on the corresponding screws 10, thereby driving the two pairs of support legs 7 to move outward. When the two pairs of support legs 7 move out of the lifting plate 5, the double-headed motor 9 stops. At this time, the lifting plate 5 can drive the double-headed motor 9 and the two screws 10 to move downward, facilitating the lowering of the dry-type transformer for maintenance or repair. After the lifting plate 5 lifts the dry-type transformer to the required position, the double-headed motor 9 drives the two screws 10 to rotate in the reverse direction, which can reset the two support legs 7 and provide stable support.
