Description

Technical Field

[0001] This utility model relates to the field of transformer oil tank technology, specifically to a transformer oil tank that is easy to install. Background Technology

[0002] The transformer oil tank is an important component of a transformer. It is used to hold transformer oil, protect the internal windings and core of the transformer, and provide heat dissipation.

[0003] Existing transformer tanks are generally manufactured by cutting and welding steel plates, without the addition of lifting hooks. This means that during installation, the tank can only be lifted to the designated position by wrapping ropes around its outer shell with a crane. However, the precise control of the rope wrapping position and method on the tank surface is difficult, potentially leading to tilting or imbalance during lifting. Uneven lifting increases the risk of the tank swaying in the air, potentially causing collisions with surrounding objects or even the tank falling. Furthermore, some designs use hooks on the top of the tank, with ropes connecting to the hooks for lifting. This method results in excessive localized stress, easily causing deformation of the upper steel plate during lifting, affecting the tank's normal operation. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a transformer oil tank that is easy to install.

[0005] The technical solution of this utility model is as follows:

[0006] A transformer oil tank that is easy to install includes a tank shell with wheels at the lower end. The tank shell includes an upper cover and a lower cover, which are connected by a side plate with heat sinks. The heat sinks are vertically arranged in the middle of the side plate. The tank shell is symmetrically provided with hoisting units on both sides along its length.

[0007] The hoisting unit has an I-shaped structure. The hoisting unit has a slot on the side near the outer shell of the enclosure. The slot is inserted into the same side of the adjacent upper end cover, lower end cover and heat sink respectively, and the sides of the upper end cover and lower end cover are located in the corresponding slots.

[0008] The hoisting unit is detachably connected to the upper and lower end covers via connectors.

[0009] The lifting unit is equipped with lifting lugs at the top, which are located above the upper cover. The lifting lugs can be connected to ropes, which are then connected to external lifting equipment to achieve lifting.

[0010] By symmetrically arranging lifting units on both sides of the tank shell, the lifting units can support the upper and lower ends of the tank shell on the same side. The lifting units are fixedly connected to the tank shell through connectors. When lifting from both sides, the weight is distributed to multiple lifting points, which reduces the force on a single lifting point of the hook in the prior art and improves the overall stability. Furthermore, by adjusting the position of the lifting points on both sides, the center of gravity of the fuel tank can be placed directly below the lifting points. Compared with lifting and installing the fuel tank by wrapping it with a lifting rope, multi-point lifting can reduce the swaying of the fuel tank and improve the stability of the lifting process.

[0011] The specific structure of the above-mentioned hoisting unit is as follows: the hoisting unit includes an upper support arm, a lower support arm, and a vertical support arm connected in an I-shape. The lifting lug is located at the middle of the upper part of the upper support arm, and the upper part of the lifting lug is inclined upward towards the side closer to the outer shell of the box. Compared with the vertically set lifting lug, it can reduce the phenomenon of excessive bending angle of the hoisting rope at the lifting lug, resulting in severe stress and wear.

[0012] The slots are positioned such that the upper support arm, lower support arm, and vertical support arm all have connected slots along their length. The vertical support arm is plugged into the heat sink, which makes it easy to install the hoisting unit directly on one side of the enclosure. The hoisting unit will not move to the sides during use, and the connectors help prevent it from falling off.

[0013] To avoid affecting the heat dissipation effect of the heat sink, both sides of the slot of the vertical support arm are equipped with a heat dissipation coating, so that the vertical support arm can conduct heat outward and dissipate heat, thereby increasing the heat dissipation area.

[0014] The specific structure of the above-mentioned connector is as follows: the connector includes a first connector and a second connector. The first connector is threaded to both sides of the lower support arm. The first connector can pass through the lower support arm and be threaded to the lower end cover.

[0015] The connection structure between the upper connector of the hoisting unit and the upper end cover is as follows: symmetrical second connectors are provided on both sides of the lifting lug and threadedly connected to the upper support arm. The lower end of the second connector passes through the upper support arm and abuts or is threadedly connected to the upper end cover. The second connector can be threadedly connected to the upper end cover. In order to reduce the need to open a separate threaded hole on the upper end cover, the second connector can also be pressed against the upper end cover, which can also achieve the effect of fixing the upper support arm and the upper end cover.

[0016] The specific structure of the lower support arm is as follows: the lower support arm includes an integrally formed first upper plate, a first connecting plate and a first lower plate. The first connecting plate is perpendicularly connected to the same side of the first upper plate and the first lower plate. The inner surfaces of the first connecting plate, the first upper plate and the first lower plate form a slot. The length of the first lower plate is greater than the length of the first upper plate.

[0017] The beneficial effects of this utility model are as follows:

[0018] The lifting units are symmetrically arranged on opposite sides of the outer shell of the transformer tank. The upper and lower parts of the lifting units are fixedly connected to the outer shell of the transformer tank through connectors. By threading ropes through the two lifting lugs and cooperating with the crane, the transformer tank can be stably lifted and installed to the preset position. The lifting units are connected to the upper and lower parts of the outer shell of the transformer tank, increasing the number of lifting points. The weight of the transformer tank is distributed to multiple lifting points. Compared with lifting the tank by wrapping it with ropes or using a single hook, multi-point lifting can reduce the swaying of the tank, improve the stability of the lifting process, and reduce the situation of large local stress on the outer shell of the transformer tank, thus reducing the deformation of the outer shell of the transformer tank during the lifting process.

[0026] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a transformer oil tank that is easy to install includes a tank shell 1. The lower end of the tank shell 1 is provided with a traveling wheel. The tank shell 1 includes an upper end cover 11 and a lower end cover 12. The upper end cover 11 and the lower end cover 12 are connected by a side plate 13 with heat sink 14. The heat sink 14 is vertically arranged in the middle of the side plate 13. The tank shell 1 is symmetrically provided with hoisting units 2 on both sides along its length direction.

[0027] The hoisting unit 2 has an I-shaped structure. A slot 25 is provided on the side of the hoisting unit 2 closest to the outer casing 1. The slot 25 is inserted into the same side of the adjacent upper end cover 11, lower end cover 12, and heat sink 14, with the sides of the upper end cover 11 and lower end cover 12 located within their respective slots 25. The hoisting unit 2 is detachably connected to the upper end cover 11 and lower end cover 12 via connectors.

[0028] See Figure 2 and Figure 3 As shown, the hoisting unit 2 includes an upper support arm 21, a lower support arm 22, and a vertical support arm 23 connected in an I-shape. The slots 25 are positioned such that the upper support arm 21, the lower support arm 22, and the vertical support arm 23 are all provided with communicating slots 25 along their length. The upper support arm 21 is inserted into one side of the upper end cover 11, the lower support arm 22 is inserted into one side of the lower end cover 12, and the vertical support arm 23 is inserted into the heat sink 14 in the middle of the side plate 13. This facilitates the direct installation of the hoisting unit 2 on one side of the outer shell 1, and the hoisting unit 2 will not move to the sides during use. The connecting parts also provide an anti-falling effect.

[0029] The upper end of the hoisting unit 2 is provided with a lifting lug 24, which is located above the upper end cover 11. The lifting lug 24 is located in the middle of the upper support arm 21, and the upper part of the lifting lug 24 is inclined upward towards the side closer to the outer shell 1. Compared with the vertically arranged lifting lug 24, it can reduce the phenomenon of excessive bending angle of the hoisting rope at the lifting lug 24, resulting in severe stress and wear.

[0030] In the above structure, by symmetrically arranging lifting units 2 on both sides of the outer shell 1, the lifting units 2 can support the upper and lower ends of the outer shell 1 on the same side. The lifting units 2 are fixedly connected to the outer shell 1 through connectors. When lifting from both sides, the weight is distributed to multiple lifting points, which reduces the force on a single lifting point of the hook in the prior art and improves the overall stability. Furthermore, by adjusting the position of the lifting points on both sides, the center of gravity of the oil tank can be placed directly below the lifting points. Compared with lifting and installing the oil tank by wrapping it with a rope, multi-point lifting can reduce the shaking of the oil tank and improve the stability of the lifting process.

[0031] To avoid affecting the heat dissipation effect of the heat sink 14, both sides of the slot 25 of the vertical support arm 23 are provided with heat dissipation coating, so that the vertical support arm 23 can conduct heat outward and dissipate heat, thereby increasing the heat dissipation area.

[0032] The specific structure of the connector is as follows: the connector includes a first connector 3 and a second connector 4. The first connector 3 is threadedly connected to both sides of the lower support arm 22. The first connector 3 can pass through the lower support arm 22 and be threadedly connected to the lower end cover 12.

[0033] The connection structure between the upper connector of the hoisting unit 2 and the upper end cover 11 is as follows: the hoisting lug 24 is symmetrically provided with second connectors 4 that are threaded to the upper support arm 21. The lower end of the second connector 4 passes through the upper support arm 21 and is pressed against or threaded to the upper end cover 11. The second connector 4 can be threaded to the upper end cover 11. In order to reduce the need to open a separate threaded hole in the upper end cover 11, the second connector 4 can also be pressed against the upper end cover 11, which can also achieve the effect of fixing the upper support arm 21 and the upper end cover 11.

[0034] The specific structure of the lower support arm 22 is as follows: the lower support arm 22 includes an integrally formed first upper plate 221, a first connecting plate 222 and a first lower plate 223. The first connecting plate 222 is vertically connected to the same side of the first upper plate 221 and the first lower plate 223. The inner surfaces of the first connecting plate 222, the first upper plate 221 and the first lower plate 223 form a slot 25. The length of the first lower plate 223 is greater than the length of the first upper plate 221, thereby increasing the contact area between the first lower plate 223 and the lower end cover 12. The upper support arm 21 includes an integrally formed second upper plate 211, a second connecting plate 212, and a second lower plate 213. The second connecting plate 212 is vertically connected to the same side of the second upper plate 211 and the second lower plate 213. The inner sides of the second connecting plate 212, the second upper plate 211, and the second lower plate 213 form a slot 25. The length of the second lower plate 213 is greater than the length of the second upper plate 211. The vertical distance between the upper surface of the first lower plate 223 and the upper surface of the second lower plate 213 is the same as the vertical distance between the lower surface of the upper cover plate and the lower surface of the lower cover plate. This facilitates the contact between the upper surface of the first upper plate 221 and the lower surface of the lower cover plate, and also facilitates the contact between the upper surface of the second upper plate 211 and the lower surface of the upper cover plate. This allows the lifting unit 2 to achieve a better lifting effect on the outer shell 1 of the housing.
