Description

Technical Field

[0001] The utility model relates to the field of lifting tools, and more specifically, to an adjustable lifting tool for European box-type transformers. Background Art

[0002] A transformer is an electrical device that changes AC voltage. It is a voltage conversion and transmission equipment that converts high-voltage AC voltage into low-voltage AC voltage suitable for industrial production and people's lives. It is widely used in industrial production and people's lives. With the development of industrial production and the improvement of people's living standards, transformers have spawned many types of fully functional and multifunctional transformers, including transformer boxes. The transformer box is a comprehensive transformer that combines the transformer body and the distribution room into one. Its interior includes a transformer room, a high-voltage distribution room, a low-voltage distribution room, a capacitor compensation room, etc., collectively referred to as a European box transformer, or simply a transformer box.

[0003] Since the transformer box is a combination of the transformer room, high-voltage distribution room, low-voltage distribution room, capacitor compensation room, etc., the volume of the transformer box will be very large. Some transformer boxes are even designed to accommodate two transformers at the same time, and their length can reach about 6 meters. Due to the increase in the volume of the transformer box, the difficulty and risk factor of lifting the transformer box are increased. In order to ensure the safe lifting of the transformer box before and after transportation, it is necessary to design a rectangular transformer box lifting tooling that is adjustable in length and width according to the length and width of the transformer box to adapt to the lifting of transformer boxes of different lengths and widths, thereby meeting the safety lifting of the transformer box before and after transportation.

[0004] Application publication number CN117361292A discloses a beam hoisting device for lifting a converter transformer body, comprising: two beam assemblies connected by transverse screws, the beam assemblies comprising a beam body, a plurality of beam screws, a support seat, and a suspension seat assembly; the beam bodies in the two beam assemblies are arranged parallel and fixed; the bottom of the beam screws is fixed to the clamp of the transformer, and the top is fixed to the top of the beam body; the bottom of the support seat rests on the clamp of the transformer, and the top is fixed to the beam body; the suspension seat assembly is fixed to the top of the beam body; the steel wire rope on the crane passes through the suspension seat assembly to lift the beam device and the transformer body together. The present invention solves the problem of transformer body hoisting without a lifting structure. The beam is an adjustable assembly structure suitable for transformers of different sizes. The width direction of the beam assembly can be adjusted by adjusting the transverse screws for positioning. All the fixing components can slide along the long axis direction of the beam assembly and then be fixed to the appropriate position.

[0005] In the above-mentioned disclosed structure, a structure connected by hanging beams is used for combined lifting. There is a lack of separate crossbeams to install the hanging plates and combination rods, which is not conducive to separate combined installation for assembly. It is also easy to cause extrusion on the surface of the transformer, resulting in poor safety and stability and insufficient adaptability, and needs to be improved. Utility Model Content

[0006] In response to the problems existing in the prior art, the purpose of the utility model is to provide an adjustable lifting tool for European box-type transformers. The crossbeam is installed by a hanging plate, and the combination rod is installed in combination with the combination plate on the side. The tool can be installed separately to form an overall frame, which is convenient for assembly and use. The lifting ropes on both sides are aligned to the bottom, and the connection width can be increased to avoid squeezing the surface, thereby ensuring the lifting and loading of the transformer box before transportation and the unloading and lifting of the transformer box after arriving at the destination, ensuring that the transformer box as a whole is not affected by the lifting clamping force during the lifting process of the transformer box, thereby ensuring that the transformer box shell is not damaged during the lifting process of the transformer box, and ensuring the overall quality of the transformer box before and after transportation.

[0007] In order to solve the above problems, the present invention adopts the following technical solutions.

[0008] The tie-down bolt is fixed on the top of the tie-down bolt and is fixed on the trolley block, and the tie-down bolt has a plurality of end caps, and the end caps are fixed on the trolley block.

[0009] Furthermore, there are four suspension ropes, which are symmetrically distributed on both sides of the transformer box.

[0010] Furthermore, there are two crossbeams, which are respectively located on both sides of the transformer box.

[0011] Furthermore, there are two rows of connection holes, which are evenly distributed on the surfaces of both ends of the hanging plate. By symmetrically distributing the hanging ropes and beams, they can be combined and aligned on both sides, which is conducive to balanced lifting, safety and stability.

[0012] Further, a sleeve hole is provided inside the reinforcing sleeve, and the sleeve hole is fixedly sleeved on one end of the annular fixing head.

[0013] Further, a locking groove is provided on one side inside the sleeve hole, and the locking groove is connected to one side of the annular fixing head.

[0014] Further, a locking screw is threadedly installed on one side of the reinforcing sleeve. A conical pressing head is provided at the end of the locking screw, and the conical pressing head is located on one side of the locking groove. By providing the locking groove inside the reinforcing sleeve and combining the locking screw with the conical pressing head, it can be locked and fixed after being pressed, ensuring the stability of the sling connection and improving the safety of hoisting.

[0015] Compared with the prior art, the advantages of the present utility model are as follows:

[0016] (1) In this solution, the cross beam is installed through the hanging plate, and the combined rod is installed through the combined plate on the side, and the integral frame can be formed by split installation, which is conducive to assembly and use. And the sling connections on both sides are aligned to the bottom, which can increase the connection width for avoidance, thus avoiding extrusion on the surface, ensuring the hoisting and loading of the transformer box before transportation and the unloading and hoisting after the transformer box reaches the destination. During the hoisting of the transformer box, the whole transformer box is not affected by the hoisting clamping force, so that the outer shell of the transformer box is not damaged during the hoisting process of the transformer box, ensuring the overall quality of the transformer box before and after transportation.

[0017] (2) By symmetrically distributing the slings and the cross beam, they can be combined and aligned to the two side positions, which is conducive to balanced hoisting, safe and stable.

[0018] (3) By providing the locking groove inside the reinforcing sleeve and combining the locking screw with the conical pressing head, it can be locked and fixed after being pressed, ensuring the stability of the sling connection and improving the safety of hoisting.
