Description

Technical Field

[0001] This utility model relates to the technical field of transformers, and in particular to a large-capacity dry-type transformer with a track-type trolley structure. Background Technology

[0002] As a core component of power transmission and distribution systems, transformers face increasingly stringent requirements regarding their application conditions and operating environment due to the continuous development of the industry and the growing demand. In the confined space of a transformer room, on-site personnel cannot move the transformer into position using hoisting methods. While installing rollers at the bottom of the transformer facilitates movement, the presence of these rollers can cause displacement due to vibrations generated during operation, hindering transformer stability. Furthermore, the conditions for removing the rollers within the transformer room are not readily available. Utility Model Content

[0003] In order to overcome the above-mentioned technical defects, the present invention provides a large-capacity dry-type transformer with a track-type trolley structure, which aims to solve at least one of the problems in the background art.

[0008] A locking assembly, which is mounted on the track-type trolley assembly and acts on the track, is used to fix the position of the transformer body relative to the track.

[0009] Compared with the prior art, the track-type trolley assembly of this utility model allows the transformer body to slide smoothly on a preset track in the transformer room, achieving precise position adjustment without the need for external lifting equipment. It is especially suitable for scenarios that require frequent relocation. In addition, a locking component is set to fix the position of the transformer relative to the track, effectively resisting the risk of displacement caused by vibration and ensuring operational stability.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] To better illustrate this utility model, a further detailed description of this utility model is provided below with reference to the accompanying drawings.

[0024] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0025] Combination Figures 1 to 3 As shown, this utility model discloses a large-capacity dry-type transformer with a track-type trolley structure, comprising:

[0026] Transformer body 1;

[0027] A track-type trolley assembly includes track wheels 21 and a track 22. The track wheels 21 are rotatably mounted on the bottom of the transformer body 1, and the track wheels 21 are slidably connected to the track 22. The track 22 is mounted on the floor of the transformer room.

[0028] The locking component 3 is installed on the track-type trolley assembly and acts on the track 22 to fix the position of the transformer body 1 relative to the track 22.

[0029] Compared with the prior art, the track-type trolley assembly of this utility model allows the transformer body 1 to slide smoothly on the preset track 22 in the transformer room, achieving precise position adjustment without the need for external lifting equipment. It is especially suitable for scenarios that require frequent relocation. In addition, a locking component 3 is set to fix the position of the transformer relative to the track 22, effectively resisting the risk of displacement caused by vibration and ensuring operational stability.

[0030] In one embodiment, the track-type trolley assembly has multiple parallel and spaced-apart moving groups 2, each moving group 2 including the track 22 and multiple track wheels 21. The spaced-apart moving groups 2 form multiple support structures, distributing the weight of the transformer body 1 and the dynamic loads generated during operation (such as electromagnetic vibration and short-circuit impact) to each moving group 2, avoiding deformation or wear of a single track 22 or wheel group due to local overload, which is especially suitable for large-volume, large-capacity transformers.

[0031] In one embodiment, the movable assembly 2 further includes a support frame 23, the upper part of which is fixedly connected to the transformer body 1, and the track wheel 21 is rotatably mounted on the bottom of the support frame 23. The support frame 23 acts as a rigid bridge between the transformer body 1 and the track wheel 21, decomposing concentrated loads into uniformly distributed stresses along the length of the support frame 23, thus avoiding metal fatigue or plastic deformation caused by localized stress concentration.

[0032] In one embodiment, the track wheel 21 has a sliding portion 211 and a limiting protrusion 212. The sliding portion 211 is slidably connected to the track 22, and the limiting protrusion 212 is connected to the sliding portion 211 and located on one lateral side of the track 22, abutting against the side of the track 22. The limiting protrusion 212 always maintains contact with the side of the track 22, forming a mechanical limit on the sliding portion 211, so that the sliding portion 211 always remains on the track 22 during movement, reducing the risk of the track wheel 21 detaching from the track 22 due to vibration, impact, or misoperation.

[0033] In one embodiment, the locking assembly 3 is disposed on the two outermost movable groups 2 located laterally. Dual-sided synchronous locking eliminates torque accumulation caused by unilateral force, prevents the transformer from tilting to one side on the track 22, maintains equipment levelness and uniform contact pressure, and extends the service life of the track wheels 21 and the track 22.

[0034] In one embodiment, the locking assembly 3 includes two extension plates 31 and two locking rods 32. The two extension plates 31 are respectively disposed on both axial sides of the track wheel 21, and the two locking rods 32 are threadedly connected to the two extension plates 31 respectively, so that the locking rods 32 have a locked position and a released position. When the locking rods 32 are in the locked position, the ends of the locking rods 32 act on the lateral side of the track 22. When the locking rods 32 are in the released position, the ends of the locking rods 32 do not act on the lateral side of the track 22. The position of the locking rods 32 is controlled by manually rotating them, thereby achieving the tightening and loosening of the locking rods 32. When the locking rods 32 are in the locked position, the friction between the ends of the locking rods 32 and the track 22 is used to lock the transformer body 1, preventing the transformer body 1 from shifting during operation and ensuring the safe and stable operation of the transformer.

[0035] In one embodiment, the track wheel 21 is rotatably connected to the two extension plates 31 via a pivot. Thus, the extension plates 31 can serve not only as a rotational support structure for the locking rod 32, but also as a rotational support structure for the pivot, achieving two goals at once and simplifying the structure.

[0036] It should be noted that, in addition to the manual structure described above for locking and unlocking, the locking assembly 3 can also adopt an automated structure. For example, based on the manual structure of the locking assembly 3 described above, a motor can be added to the locking rod 32 to control the position of the locking rod 32.

[0037] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
