Description

Technical Field

[0001] This utility model relates to the field of transformer processing technology, and in particular to a special lifting tool for transformer processing. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core.

[0003] A special lifting tool for transformer installation, disclosed in CN212712463U, includes a base, with support plates movably connected to the four corners of the base via bolts. Universal wheels are fixedly connected to the inner sides of each of the four support plates. A support rod is fixedly connected to the upper right side of the base, and a support frame is fixedly connected to the upper end of the support rod. This utility model is equipped with lifting components and fixing clamps. When a diesel generator drives an electric winch to lower the wire rope through a pulley system, the fixing clamps on both sides are placed on the bottom of the transformer. Then, the electric winch retracts the wire rope, causing the fixing clamps to tighten under the influence of gravity through the lifting components and the rotating shaft, thus firmly fixing the transformer between them and lifting it to the utility pole for installation. This method is cost-effective and highly practical.

[0004] However, a thorough reading of the aforementioned patent documents reveals the following drawbacks: due to the lack of a protective mechanism on the lifting device, the transformer is prone to movement during use, especially in windy weather, which could lead to the transformer tipping over, posing safety hazards and inconvenience, and thus requires improvement.

[0005] Therefore, this application proposes a special lifting tool for transformer processing to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a special lifting tool for transformer processing, which has the effect of protecting the transformer and also facilitates the lifting of transformers of different specifications.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a special lifting tool for transformer processing, comprising a lifting component, a transformer, and a fixing mechanism;

[0008] The bottom of the lifting component is fixedly connected to three lifting ropes, and one end of each of the three lifting ropes is fixedly connected to a lifting plate. The lifting component is provided with a fixing mechanism, and the fixing mechanism and the three lifting plates are connected to the same transformer.

[0009] The fixing mechanism includes a second lifting rope, a second lifting plate, a winding shaft, a protective steel wire, a motor, a limit block, and a slot. The bottom of the lifting component is fixedly connected to the second lifting rope, and one end of the second lifting rope is fixedly connected to the second lifting plate. The second lifting plate abuts against the transformer. Through the coordinated design of the three components—the first lifting plate, the first lifting rope, and the fixing mechanism—not only can the transformer be protected, but it also facilitates the lifting of transformers of different specifications.

[0010] A further feature of this invention is that a groove is provided on the second hanging plate, and a winding shaft is rotatably connected in the groove for winding up the protective steel wire.

[0011] A further feature of this invention is that a protective steel wire is fixedly connected to one side of the second hanging plate, and one end of the protective steel wire passes through the three first hanging plates and is engaged with the winding shaft.

[0012] A further feature of this invention is that a groove is provided on the second hanging plate, and a motor is fixedly installed in the groove. The output end of the motor is fixedly connected to one end of the winding shaft to drive the winding shaft.

[0013] A further feature of this invention is that a slot is provided on the winding shaft, the slot being adapted to the protective steel wire, so as to facilitate the winding shaft in winding the protective steel wire.

[0014] A further feature of this invention is that one end of the protective steel wire is fixedly connected to a limiting block, the limiting block being larger than the slot, to prevent the protective steel wire from detaching from the slot.

[0015] A further feature of this invention is that each of the three hanging plates has a through hole that is compatible with the protective steel wire, so that the protective steel wire can tighten and fix the three hanging plates.

[0016] A further feature of this invention is that each of the three hanging plates has an installation groove, which corresponds to the through hole. A pulley is rotatably connected in the installation groove, and the pulley is adapted to the protective steel wire to reduce the wear of the protective steel wire.

[0017] A further feature of this invention is that: bearings are fixedly connected to both ends of the winding shaft, and the outer walls of the two bearings are fixedly connected to the hanging plate, which facilitates the rotation of the winding shaft.

[0018] A further feature of this invention is that a protective plate is fixedly connected to one end of each of the three hanging plates and the second hanging plate, and the multiple protective plates abut against the transformer, thereby further enhancing the protective effect through the action of the multiple protective plates.

[0019] The beneficial effects of this utility model are: through the coordinated design of the three hanging plates, the hanging rope and the fixing mechanism, not only can the transformer be protected, but it is also convenient to lift transformers of different specifications, which greatly improves safety and practicality.

[0029] Reference Figures 1-5 A special lifting tool for transformer processing includes a lifting component 1, a transformer 4, and a fixing mechanism 5;

[0030] The bottom of the lifting component 1 is fixedly connected to three lifting ropes 2, and one end of each of the three lifting ropes 2 is fixedly connected to a lifting plate 3. The lifting component 1 is equipped with a fixing mechanism 5, and the same transformer 4 is provided between the fixing mechanism 5 and the three lifting plates 3. The fixing mechanism 5 is connected to the three lifting plates 3.

[0031] The fixing mechanism 5 includes a second lifting rope 51, a second lifting plate 52, a winding shaft 53, a protective steel wire 54, a motor 55, a limit block 56, and a slot 57. The bottom of the lifting component 1 is fixedly connected to the second lifting rope 51, and one end of the second lifting rope 51 is fixedly connected to the second lifting plate 52. The second lifting plate 52 abuts against the transformer 4. Through the coordinated design of the three first lifting plates 3, the first lifting rope 2, and the fixing mechanism 5, not only can the transformer 4 be protected, but it is also convenient to lift transformers 4 of different specifications.

[0032] In this method, a groove is provided on the second hanging plate 52, and a winding shaft 53 is rotatably connected in the groove for winding the protective steel wire 54. Both ends of the winding shaft 53 are fixedly connected to bearings, and the outer walls of the two bearings are fixedly connected to the second hanging plate 52 to facilitate the rotation of the winding shaft 53.

[0033] In this method, a protective steel wire 54 is fixedly connected to one side of the second hanging plate 52. The protective steel wire 54 and the second hanging plate 52 are detachably connected, which facilitates the replacement of the protective steel wire 54. One end of the protective steel wire 54 passes through the three first hanging plates 3 and is engaged with the winding shaft 53. Through the interaction between the protective steel wire 54, the second hanging plate 52 and the three first hanging plates 3, the effect of protecting the transformer 4 from all sides can be achieved. Protective steel wires 54 of different lengths are prepared in advance, and the appropriate length of protective steel wire 54 is selected according to the size of the transformer 4. At the same time, an appropriate number of protective steel wires 54 are installed on the second hanging plate 52 according to the actual situation.

[0034] In this method, a groove 2 is provided on the second hanging plate 52, and a motor 55 is fixedly installed in the groove 2. The output end of the motor 55 is fixedly connected to one end of the winding shaft 53 to drive the winding shaft 53.

[0035] In this method, a slot 57 is provided on the winding shaft 53, which is adapted to the protective steel wire 54, so that the winding shaft 53 can easily wind up the protective steel wire 54.

[0036] In this method, one end of the protective steel wire 54 is fixedly connected to a limiting block 56, which is larger than the slot 57 to prevent the protective steel wire 54 from disengaging from the slot 57.

[0037] In this method, each of the three hanging plates 3 has through holes that are compatible with the protective steel wire 54, so that the protective steel wire 54 can tighten and fix the three hanging plates 3.

[0038] In this method, each of the three hanging plates 3 has an installation groove 1, which corresponds to the through hole. A pulley 7 is rotatably connected in the installation groove 1. The pulley 7 is adapted to the protective steel wire 54 to reduce the wear of the protective steel wire 54.

[0039] In this method, one end of each of the three hanging plates 3 and 52 is fixedly connected to a protective plate 6, and the multiple protective plates 6 are in contact with the transformer 4. The protective effect is further enhanced through the action of the multiple protective plates 6.

[0040] Working principle: In use, first fix one end of the protective steel wire 54 to the second hanging plate 52 and pass the other end through the through holes on the three first hanging plates 3 in sequence. Then, place the second hanging plate 52 and the three first hanging plates 3 around the transformer 4, and hook one end of them to the bottom of the transformer 4. Then, insert one end of the protective steel wire 54 into the slot 57 on the winding shaft 53. Then, start the motor 55. At this time, the winding shaft 53 is driven by the motor 55 to rotate on the second hanging plate 52. Through the interaction between the slot 57 and the limiting block 56, the protective steel wire 54 is wound up. At the same time, the protective steel wire 54 interacts with the second hanging plate 52 and the three first hanging plates 3 and binds and tightens them, thereby achieving the effect of protecting the transformer 4.

[0041] The technological advancements of this invention compared to existing technologies are as follows: the cooperation of various components can achieve the protection of transformer 4 and facilitate the lifting of transformers 4 of different specifications, thereby improving safety and applicability. Moreover, the structure is simple and the practicality is higher.
