Description
Technical Field
[0001] The utility model relates to the technical field of transformer oil tank installation, in particular to a transformer oil tank which is easy to lift. Background Art
[0002] The transformer oil tank (also called "corrugated oil tank") is a box container for transformer oil. However, the oil in the transformer oil pillow cannot be too full. The oil tank is connected to the oil pillow through a pipeline. When the oil tank is short of oil, the oil in the oil pillow will flow down the pipeline and be added to the oil tank to keep it full of oil. At the same time, when the transformer load increases, the oil temperature rises, the transformer oil expands, and the oil tank cannot hold it, it will also flow up the pipeline and flow back to the oil pillow. The transformer oil tank is the outer shell of the transformer, which contains the iron core and coil and is filled with transformer oil, so that the iron core and coil are immersed in the oil. Transformer oil plays an insulating and heat dissipating role. Large transformers generally have two oil tanks, one is the main body oil tank; the other is the on-load voltage regulating oil tank, which is equipped with a switching switch.
[0003] The existing transformer oil tank has a certain weight. When installing the transformer oil tank, firstly, a binding rope and a fixed lock are generally used to tie the entire transformer oil tank tightly, and then a crane is operated to lift the tied transformer oil tank. In addition, since the transformer oil tank itself does not have a hook lock component, the lifting lock of the crane needs to be hooked on the binding rope that ties the transformer oil tank tightly. However, the supporting force of the binding rope is weak, and it is easy to shake when the crane is operated to lift the transformer oil tank body, which affects the stability of the transformer oil tank when lifting.
[0004] Therefore, it is urgent to propose a transformer oil tank that is easy to lift. Utility Model Content
[0005] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a transformer oil tank which is easy to lift.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0025] Embodiment: A transformer oil tank that is easy to lift, such as Figure 1-Figure 3 As shown, it includes a transformer oil tank 1, a fixing plate Ⅰ101, a suspension rod Ⅰ102, a heat dissipation pipe 2, a terminal 3, an oil pillow 4 and a bracket 5. A fixing plate Ⅰ101 is welded at the middle position of the top of the transformer oil tank 1, and a suspension rod Ⅰ102 is fixed at the middle position of the top of the fixing plate Ⅰ101. The suspension rod Ⅰ102 is a semicircular ring with a transverse protrusion, which is convenient for being locked by a hook. The left and right end surfaces and the front end surface of the transformer oil tank 1 are both equipped with heat dissipation pipes 2, which are basic components for accelerating the heat transfer of cooling oil. The front and rear sides of the top of the transformer oil tank 1 are symmetrically equipped with terminal 3 through fixing parts. The terminal 3 on the front and rear sides are at different heights, with the front bottom and the rear high. An oil pillow 4 is fixedly arranged on the right side of the top of the transformer oil tank 1 through a mounting frame. The oil pillow 4 is an oil storage device of the transformer oil tank 1. The left and right sides of the bottom of the transformer oil tank 1 are symmetrically equipped with brackets 5, which are the basic connecting seat of the transformer oil tank 1.
[0026] like Figure 1-Figure 3 As shown, a fixing frame 6 is also included. A fixing frame 6 is detachably mounted on the middle position of the outer side of the transformer oil tank 1. The fixing frame 6 performs basic fixation on the transformer oil tank 1 and further provides installation space for the hook lock component.
[0027] like Figure 3As shown, it also includes a fixing plate II 7. The fixing plates II 7 are symmetrically arranged on both sides of the bottom of the fixing frame 6, and the tops of the fixing plates II 7 on both sides are connected to the bottom of the transformer oil tank 1. The fixing plates II 7 further fix the fixing frame 6 on the transformer oil tank 1 to provide a tightening effect.
[0028] like Figure 1 and Figure 3 As shown, a universal wheel 8 is also included. The bottom of the fixing plate II 7 is symmetrically provided with the universal wheel 8 by screws. The universal wheel 8 is used to move the position of the transformer oil tank 1, and the universal wheel 8 itself has a stop mechanism.
[0029] like Figure 1 and Figure 3 As shown, a hanger 9 is also included. The hangers 9 are symmetrically arranged on the front and rear sides of the top of the fixing frame 6 by screws. The hanger 9 is a hook lock component that further assists the transformer oil tank 1 in lifting on the basis of the hanger rod Ⅰ102.
[0030] like Figure 1-Figure 2 As shown, it also includes a fixing plate III 10, and the fixing plates are symmetrically arranged on both sides of the top of the fixing frame 6 by screws.
[0031] Ⅲ10, and the bottoms of the fixing plates Ⅱ7 on both sides are connected to the top of the transformer oil tank 1, which are connecting parts for further fastening the fixing frame 6 and the transformer oil tank 1.
[0032] like Figure 1-Figure 2 As shown, it also includes a suspension rod II 11, which is a vertically protruding semicircular ring. The suspension rods II 11 are symmetrically arranged on both sides of the top of the fixed plate III 10. The suspension rod II 11 is used to increase the number of hook locks of the hook on the basis of the suspension rod I 102 to better maintain the stability when lifting the transformer oil tank 1.
[0033] like Figure 1-Figure 2 As shown, a protective frame 12 is also included. The protective frame 12 is symmetrically arranged on the outside of the heat pipe 2. The protective frame 12 covers the heat pipe 2. The protective frame 12 is a hollow shielding frame. Heat dissipation ports are symmetrically opened on both sides of the heat pipe 2 to maintain the heat dissipation effect on the outside of the heat pipe 2.
[0034] like Figure 1 As shown, a protective plate 13 is also included. The protective plates 13 are symmetrically arranged on both sides of the top of the transformer oil tank 1, and the protective plates 13 on both sides are located on the front and rear sides of the fixed plate Ⅰ101 and are adjacent to the terminal 3. The protective plates 13 block the terminal 3 to prevent it from being hit during lifting.
[0035] When it is necessary to lift the equipment, first hold the lifting rod Ⅱ11 on one side to push the transformer oil tank 1 to move the transformer oil tank 1. Under the action of the protective frame 12, the heat dissipation pipe 2 of the transformer oil tank 1 will not be bumped by the equipment in the factory during the movement. When the transformer oil tank 1 moves to the designated lifting position, control the crane hook to descend, and use the hook to hook the lifting rod Ⅰ102 on the fixed plate Ⅰ101 on the top of the transformer oil tank 1, and at the same time use the hook to hook the hanger 9 on the fixed frame 6. After all the lifting rods Ⅰ102, lifting rods Ⅱ11, and hangers 9 in all directions are hooked and locked by the hook of the crane, the crane can be controlled to lift the transformer oil tank 1. Under the action of the protective plate 13, the chain of the crane will not contact the terminal 3 on both sides when lifting the transformer body, so that the terminal 3 is shielded to prevent the terminal 3 from being collided. When the crane completes the lifting of the transformer oil tank 1, the crane is controlled to lower the transformer oil tank 1 to the designated installation position, and then the lifting lock is removed and unlocked to complete the operation.
[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
