Description

Technical Field

[0001] The utility model belongs to the technical field of oblique racks for power transformers, in particular to an oblique rack for power transformers. Background Art

[0002] A transformer is a stationary electrical device used to convert AC voltage and current to transmit AC power. It achieves this transfer based on the principle of electromagnetic induction. Transformers can be categorized by their application as power transformers, test transformers, instrument transformers, and special-purpose transformers. Power transformers are essential for power transmission and distribution, as well as for user distribution. Test transformers perform withstand voltage tests on electrical equipment, while instrument transformers are used for electrical measurement and relay protection in distribution systems. Special-purpose transformers include smelting furnace transformers, welding transformers, electrolysis rectifier transformers, and small voltage-regulating transformers.

[0003] Problems with existing technologies:

[0004] Most existing transformers are fastened to utility poles through fixed frames, and then connected to the utility poles through diagonal support assemblies to provide additional support and balance. However, the diagonal support assemblies may shake due to wind or other reasons, which can easily cause the screws to loosen, thereby rendering the fastening ineffective, losing the diagonal support effect, and causing it to slide. Utility Model Content

At the same time, the first fixed shaft drives the pushing plate to push the top tightening plate to apply a tightening pressure to the electric pole, and at the same time, the top tightening plate relies on the support of the first inclined supporting plate to push the second inclined supporting plate away from the electric pole, so that the fastening ring can be provided with a push-pull force after tightening, thereby improving the fixing effect.

[0011] Preferably, the oblique support mechanism is provided in two pieces and each piece includes two second oblique support plates and a fastening ring. The fastening ring is provided in two symmetrical semicircular ring shapes and is both sleeved with the movable shaft. The lower side of the second oblique support plate is sleeved with the movable shaft. The fastening ring is sleeved on the electric pole through a fastening bolt.

[0015] Preferably, the fixing frame includes two fixed square steels, and a plurality of fixed angle irons are welded to the bottom surfaces of the two fixed square steels. Two movable angle irons are provided on the bottom surfaces of the two fixed square steels. The movable angle irons are connected to the fixed angle irons on the sides through fastening rods, and two inner sleeve shafts are fixed between the two fixed square steels.

[0016] Preferably, the fixed angle iron on one side is connected to the two second diagonal support plates by bolts.

[0017] The beneficial effects are:

[0018] The utility model is characterized in that the movable mechanism is pressed down by the transformer, and the supporting mechanism is pressed down by the weight of the transformer itself, so that the oblique supporting mechanism and the electric pole are pushed away from each other by the oblique supporting plate and the push plate, so that the supporting force of the oblique supporting mechanism and the electric pole is increased, and the pulling force of the fastening bolt is increased, thereby improving the fastening effect of the oblique supporting mechanism and the electric pole after being connected, always maintaining the support and improving the fixing effect.

[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0027] like Figure 1-5 As shown, a diagonal rack for a power transformer includes a tightening mechanism 1 and a fixing frame 4. The fixing frame 4 is provided with a movable mechanism 3 for pressing down the tightening mechanism 1. The fixing frame 4 is provided with an oblique support mechanism 2 for supporting the fixing frame 4. Both are connected to a power pole 6. The oblique support mechanism 2 and the power pole 6 are connected to the tightening mechanism 1 for tightening.

[0028] The tightening mechanism 1 is provided with two and each includes a lower pressing plate 102 and two first fixed shafts 103. The lower side of the lower pressing plate 102 is sleeved with a second fixed shaft 104. The opposite sides of the two first fixed shafts 103 are respectively fixed with a sleeve frame 101. The second fixed shaft 104 is fixed to the opposite sides of the two sleeve frames 101.

[0029] A tightening plate 107 is provided below the lower pressure plate 102, and the tightening plate 107 is clamped with the electric pole 6 through the provided clamping rod groove. A pushing plate 105 is provided on the side of the tightening plate 107. The upper side of the pushing plate 105 is sleeved with the first fixed shaft 103, and the lower side of the pushing plate 105 is sleeved with the third fixed shaft 106. The third fixed shaft 106 is fixed on the side of the tightening plate 107. The tightening plate 107 is correspondingly provided with a first diagonal support plate 109. The upper side of the first diagonal support plate 109 is sleeved with the fourth fixed shaft 108, and the fourth fixed shaft 108 is fixed on the tightening plate 107.

[0030] Refer to the attached Figure 3 The oblique support mechanism 2 is provided with two and each includes two second oblique support plates 21 and a fastening ring 23. The fastening ring 23 is provided in the shape of two symmetrical semicircular rings and is both sleeved with the movable shaft 22. The lower side of the second oblique support plate 21 is sleeved with the movable shaft 22. The fastening ring 23 is sleeved on the electric pole 6 through the fastening bolt 24. With such a configuration, the fastening ring 23 can be fastened to the electric pole 6 by the fastening bolt, thereby relying on the fastening ring 23 to support the second oblique support plate 21.

[0031] Furthermore, the two second diagonal support plates 21 are respectively connected to the two sleeve frames 101, and the two second diagonal support plates 21 are fixedly connected to the fifth fixed shaft 110. The fifth fixed shaft 110 is sleeved on the lower side of the first diagonal support plate 109. In this way, the first diagonal support plate 109 can be relied upon to provide a supporting effect for the tightening plate 107, thereby ensuring that when the tightening plate 107 is subjected to a downward thrust, the first diagonal support plate 109 is relied upon to push the tightening plate 107 against the electric pole 6 for tightening.

[0032] Refer to the attached Figure 4The movable mechanism 3 includes two support plates 31, which are arranged between two fixed square steels 41. Movable holes 34 are opened on both sides of the two support plates 31. The four movable holes 34 are divided into two groups and are respectively connected to two inner sleeve shafts 43. The internal height of the movable holes 34 is set to three times the diameter of the inner sleeve shaft 43, so that when the movable mechanism 3 is pressed down by the transformer 5, it provides downward displacement space.

[0033] Furthermore, two sixth fixed shafts 33 are provided below the two support plates 31, and the sixth fixed shaft 33 is fixed between the two fixed plates 32. The two fixed plates 32 are respectively fixed on one side of the bottom surface of the two support plates 31. The two fixed plates 32 are arranged between two adjacent fixed angle irons 42. The two support plates 31 are installed with transformers 5, so that the support plates 31 are pressed down by relying on their own weight of the transformer 5, and at the same time, the sixth fixed shaft 33 on the fixed plate 32 is driven to press down the tightening mechanism 1, thereby providing downward pressing power to the tightening mechanism 1.

Two movable angle irons 45 are provided on the bottom surfaces of the two fixed square steels 41. The movable angle irons 45 are connected to the fixed angle irons 42 on the sides through fastening rods 44. Two inner sleeve shafts 43 are fixed between the two fixed square steels 41. The electric pole 6 is located between the two fastening rods 44 and between the fixed angle irons 42 and the movable angle irons 45, so as to facilitate the fixing of the fixing frame 4 on the two electric poles 6.

[0035] Furthermore, the fixed angle iron 42 on one side is connected to the two second diagonal support plates 21 by bolts, so that the fixing frame 4 can rely on the second diagonal support plates 21 for additional support and balance.

[0036] With the above structure, the fixing frame 4 is first installed on the two electric poles 6, and then the fastening ring 23 on the oblique support mechanism 2 is fastened to the electric pole 6, and the top tightening plate 107 on the tightening mechanism 1 is adjusted to rest on the electric pole 6. At the same time, the tightening mechanism 1 also drives the support plate 31 on the movable mechanism 3 to move upward, so that the movable hole 34 on the support plate 31 moves upward and slides along the inner sleeve shaft 43. In this way, the transformer 5 can be installed on the support plate 31, so that the transformer 5 can rely on its own weight to support the support plate 31. Press down, and at the same time drive the lower pressure plate 102 to press down the first fixed shaft 103 and the sleeve frame 101, so that the sleeve frame 101 slides down along the second diagonal support plate 21, and at the same time the first fixed shaft 103 drives the push plate 105 to push the tightening plate 107 to apply tightening pressure to the electric pole 6, and at the same time the tightening plate 107 relies on the support of the first diagonal support plate 109 to push the second diagonal support plate 21 away from the electric pole 6, so that the push-pull force after tightening can be provided to the fastening ring 23, thereby improving the fixing effect.
