Description

TECHNICAL FIELD

[0001] The present application belongs to the field of power facility construction, and relates to an assembled transformer installation tool. BACKGROUND

[0002] In the field of power facility construction and maintenance, as the core equipment for power conversion and distribution, the installation quality of the transformer directly affects the stable operation of the power system. The traditional transformer installation method mainly relies on on-site welding or bolted support, which usually adopts a monolithic structure. A plurality of fixing points are welded on the power pole in advance, and then the transformer is lifted to the installation position by manual carrying. Due to the heavy weight of the transformer (usually more than 2 tons), multiple people are required to operate on site, and the installation process is limited by the distance between the power poles and the terrain conditions. Problems such as deviation of the support level and stress concentration of the fixing points may occur, resulting in low installation efficiency and safety hazards.

[0003] Although adjustable installation supports exist in the prior art, they mostly use simple screw adjustment mechanisms or hydraulic lifting devices. For example, some supports adjust the position by setting multiple bolt holes on the cross beam, but this adjustment method has a limited adjustment range and cannot achieve fine adjustment. Some other schemes use a lifting platform driven by a hydraulic cylinder, which can adjust the height but cannot adjust the level of the transformer. Moreover, the traditional method uses chains or steel wires to directly bind the transformer body, which may cause damage to the surface of the equipment. In addition, it is difficult to maintain the horizontal state during lifting. Some improved schemes use a four-point lifting structure, but the lifting point position is fixed and cannot be dynamically adjusted according to the center of gravity of the equipment. When the transformer is transversely shifted between the power poles, the lifting device needs to be disassembled and re-fixed multiple times, which not only increases the operation time but also may cause the equipment to shake due to the change of the lifting point, threatening the safety of the operators. SUMMARY

DETAILED DESCRIPTION

[0036] The present application will be described in greater detail by way of specific embodiments, and as such, those skilled in the art can easily understand other advantages and purposes of the present application from the contents disclosed in the specification. The present application can also be implemented or applied by other different embodiments, and the details in the specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present application.

[0037] As Figure 1 shown in the assembled transformer mounting tool, two power poles 1 are the support base of the entire mounting tool, and the embedding depth of the power poles 1 is determined according to the geological conditions, generally not less than 2.5 m in soft soil foundation, not less than 1.8 m in hard soil foundation, and the verticality deviation of the pole body is not more than 0.5% of the pole height.

[0038] The transformer 3 is the main load-bearing object of the installation tool. Three second channel steels 10 are arranged at the bottom of the transformer 3. The second channel steel 10 is selected from a 12# hot-rolled channel steel, and the length is 200mm to 300mm longer than the width of the bottom of the transformer 3. Four to six rollers 12 are installed in the second channel steel 10 through bearings. The nylon roller 12 is selected, which has the characteristics of wear resistance and self-lubrication, can reduce the friction between the first channel steel 9, and facilitates the movement of the transformer 3 on the support frame 2. The second channel steel 10 is used to support the transformer 3, and facilitates the assembly of the transformer 3 and the support frame 2.

[0039] As shown in Figure 2 The support frame 2 is the core part of the installation tool, which is composed of two groups of first hoops 5, cross beams 8, first channel steels 9, third channel steels 11 and support rods 13. The first hoop 5 is made of flat steel and is fastened on the power pole 1 by bolts. The bolt is selected from a M20 high-strength bolt to ensure that the first hoop 5 is firmly connected with the power pole 1.

[0040] A plurality of cross beams 8 are movably arranged between the two groups of first hoops 5. The cross beam 8 is made of channel steel, and the length is determined according to the distance between the two power poles 1. The distance between the cross beams 8 is designed according to the size and weight of the transformer 3. For small transformers 3, the distance between the cross beams 8 can be set to 800mm; for large transformers 3, the distance between the cross beams 8 can be appropriately reduced to 600mm to ensure that the support frame 2 has sufficient strength and stability. The top of the plurality of cross beams 8 is fixed with a plurality of first channel steels 9 by welding. The first channel steel 9 is selected from a hot-rolled channel steel, and the opening is arranged upward. The full welding process is adopted during welding, and the weld height is not less than 6mm to ensure that the first channel steel 9 is firmly connected with the cross beam 8.

[0041] The third channel steel 11 is arranged on the first channel steel 9. The third channel steel 11 is also selected from a 10# hot-rolled channel steel, and the length is determined according to the size of the radiator. At least two support rods 13 are welded at the top of the third channel steel 11. The support rod 13 is selected from a steel pipe, and the wall thickness is not less than 5mm. The top of the plurality of support rods 13 is fixed with the same bottom plate 14 for supporting the radiator by welding. The bottom plate 14 is made of a 6mm thick pattern steel plate, which can increase the friction between the radiator and the bottom plate 14 to prevent the radiator from sliding. The third channel steel 11 also has four to six rollers 12 installed in it through bearings. The cooperation of the third channel steel 11, the support rod 13 and the bottom plate 14 is used to support the radiator outside the transformer 3, which facilitates the assembly of the radiator and the support frame 2.

[0042] The second and third channel steels 10, 11 are each secured to the first channel steel 9 via first bolts 15. These are M16 high-strength bolts, with a bolt spacing of 150 to 200 mm. To connect, first place the second channel steel 10 on the first channel steel 9, allowing the roller 12 to fit inside the first channel steel 9. Then, place the third channel steel 11 on the first channel steel 9. Once the positions are adjusted, secure the three components together with the first bolts 15.

[0043] like Figure 3 The illustrated fixing assembly is positioned below the first clamp 5 and is used to support and secure the adjusted support frame 2. The fixing assembly includes two sets of second clamps 16, each secured to the power pole 1 by bolts using the same bolt structure and material as the bolts of the first clamp 5. A second turret 17 is pivotally mounted outside the two second clamps 16 on the same side. The structure of the second turret 17 is similar to that of the first turret 6.

[0044] like Figure 5 The first turret 6 and the second turret 17 shown are both composed of two second connecting beams 28 and a first connecting beam 25. The first connecting beam 25 is made of No. 10 channel steel. Two second fixing plates 27, made of flat steel, are welded to one side of the first connecting beam 25. A sliding beam 26, made of rectangular tube, is inserted between the second fixing plates 27 and the first connecting beam 25. The sliding beam 26 is movable within the second fixing plates 27 and is secured and adjusted by a clamp. The two second connecting beams 28 are welded to one side of the sliding beam 26 and the first connecting beam 25, respectively, using fillet welds with a weld height of no less than 5 mm.

[0045] Two rotating bases 18 are fixedly connected to the adjacent sides of the first and second rotating frames 6, 17. A connecting rod 19 is pivotally mounted between the two corresponding rotating bases 18. Connecting rod 19 is made of flat steel, and its length is determined by the distance between the first and second rotating frames 6, 17, allowing the second rotating frame 17 to be adjusted along with the first rotating frame 6. A support arm 20, made of flat steel, is pivotally mounted on one side of the longitudinal beam 7 via a rotating shaft. During installation, holes are drilled on-site according to the support angle and secured with bolts.

[0046] The first rotating frame 6 is rotatably set on the outer side of the two first clamps 5 on the same side. The longitudinal beam 7 is rotatably set on one side of the first rotating frame 6 through the connecting shaft 21. The connecting shaft 21 is made of round steel and its two ends are connected to the first rotating frame 6 and the longitudinal beam 7 through shaft sleeves. One end of multiple cross beams 8 is welded to one of the longitudinal beams 7, and double-sided welding is used during welding. The first fixing plate 22 is welded to the bottom of the cross beam 8. The first fixing plate 22 is made of flat steel. Figure 4 An extension beam 23 is inserted between the first fixing plate 22 and the crossbeam 8. The extension beam 23 is made of a rectangular tube and can move inside the crossbeam 8. After being adjusted into place, it is fixed by bolts on the crossbeam 8.

[0047] like Figure 6 The illustrated sling 4 is mounted on the support frame 2 and is used in conjunction with a crane to lift the support frame 2. The sling 4 includes a base 29 welded from two 25 mm thick steel plates. First steel wire ropes 30, selected for their high flexibility and tensile strength, are connected to the four corners of the top of the base 29. The top ends of the four first steel wire ropes 30 are connected to lifting rings 31, which are attached to the hooks 37. These lifting rings 31 are made of bent 50 mm diameter round steel to avoid stress concentration.

[0048] like Figure 7 The base 29 shown is provided with an adjustable extension arm 33, constructed from a steel square tube. Four guide cylinders 38, constructed from seamless steel tubes, are fixedly mounted within the base 29. Rotating arms 32 are rotatably mounted on the outer walls of the guide cylinders 38 via deep-groove ball bearings. The extension arm 33 is inserted into the rotating arm 32 to a depth of at least 200 mm.

[0049] like Figure 8 The guide cylinder 38 shown is equipped with a spline pin 40, which mates with the extension arm 33 and has spline teeth on its surface. A spring 39, made of spring steel, is housed within the guide cylinder 38. The spline pin 40 slides within the guide cylinder 38, with the ends of the spring 39 abutting the bottom of the spline pin 40 and the bottom wall of the guide cylinder 38, respectively, via spring seats. The spring 39 is secured by welding. Spline holes 43, which mate with the spline pin 40, are defined at the tops of both the pivot arm 32 and the extension arm 33.

[0050] A rectangular hole is formed on one side of each of the two guide cylinders 38 on the same side. A connecting bar 41 is slidably mounted within the two rectangular holes. The connecting bar 41 is made of steel plate and welded to the spline pins 40 at both ends using a full-weld process. A sliding rod 42 corresponding to the first steel wire rope 30 is slidably mounted through the top of the base 29. The sliding rod 42 is made of round steel and is fixedly connected to the corresponding connecting bar 41 by welding at the bottom. The top of the sliding rod 42 is fixedly connected to the first steel wire rope 30 using a wire rope chuck, with no fewer than three chucks.

[0051] A jack 34, a manual hydraulic jack, is fixed to one side of the rotating arm 32. A guide pulley 35, rotatably mounted on one side of the extension arm 33, is mounted via a deep-groove ball bearing. One end of a second wire rope 36 is fixedly connected to the output end of the jack 34 using a wire rope chuck, with at least three chucks. The middle section of the second wire rope 36 rests on the guide pulley 35, which guides it, ensuring smooth movement during the lifting process. Hook slots 24, compatible with hooks 37, are located at the bottom of each side beam 8.

[0052] The assembled transformer mounting tool is used, first, two second hoops 16 and two first hoops 5 are clamped on two power poles 1, and the sliding beam 26 is inserted into the first connecting beam 25. The insertion depth of the sliding beam 26 is adjusted, and the first rotating frame 6 and the second rotating frame 17 are adapted to the spacing of the power poles 1.

[0053] The transformer 3 is lifted by the crane to above the support frame 2, and the roller 12 below the second channel steel 10 is slowly lowered into the first channel steel 9. During the lowering process, it is ensured that the transformer 3 is stable, and the roller 12 is prevented from being stuck or damaged. When the roller 12 is completely lowered into the first channel steel 9, the position of the transformer 3 is checked whether it is centered, and if there is deviation, the position of the crane can be adjusted to correct it.

[0054] The radiator to be installed outside the transformer 3 is lifted by the crane to above the support frame 2, and the roller 12 below the third channel steel 11 is also lowered into the first channel steel 9. Similarly, during the lowering process, the radiator is ensured to be stable, and the support frame 2 is prevented from being collided. The radiator is pushed, and the third channel steel 11 is aligned with the second channel steel 10, at this time, the distance between the radiator and the transformer 3 is controlled at 80mm to 100mm. The third channel steel 11, the second channel steel 10 and the first channel steel 9 are fixed by using the M16 first bolt 15, and when the bolt is tightened, it is tightened in the diagonal order to ensure firm connection.

[0055] The rotating arm 32 is turned on the guide cylinder 38, and during the turning process, it is slowly and stably turned to prevent the rotating arm 32 from being stuck. At the same time, the extension arm 33 is pulled to move outward in the rotating arm 32, and the moving distance is determined according to the lifting position. When the spline holes 43 on the rotating arm 32 and the extension arm 33 are aligned with the spline holes 43 on the guide cylinder 38, the lifting ring 31 is hung on the hook of the crane.

[0056] When the crane is lifted, the first steel wire rope 30 is stressed to drive the sliding rod 42 to move upward, the sliding rod 42 drives the spline pin 40 to move upward through the connecting strip 41, the spline pin 40 is inserted into the spline holes 43 of the rotating arm 32 and the extension arm 33, and the fixing of the rotating arm 32 and the extension arm 33 is realized.

[0057] The support frame 2 is moved to above the installation position of the transformer 3 by the crane, and the hook 37 at the bottom end of the second steel wire rope 36 is hung in the hook groove 24 at the bottom of the cross beam 8, and after hanging, a reverse cone is formed to avoid contact between the steel wire rope and the transformer 3. The crane is used again to lift to the installation height, and during the lifting process, the balance of the support frame 2 is closely observed, and if there is inclination, the lifting speed of the crane is adjusted in time.

[0058] The levelness of the transformer 3 is observed using a level meter, and the level meter is selected to have a precision of 0.02 mm / m. When the transformer 3 is inclined left and right, the left or right jack 34 is started, and the length of the extension of the jack 34 is adjusted according to the inclination angle, and the maximum extension is 180 mm. The extension of the jack 34 drives the movement of the end of the second steel wire rope 36, and the length of the sag of the second steel wire rope 36 is adjusted so that the left and right horizontal deviation of the transformer 3 does not exceed 2 mm. At the same time, the extension beam 23 slides in the cross beam 8, and after the adjustment is completed, the extension beam 23 and the cross beam 8 are fixed using M12 bolts.

[0059] When the transformer 3 is inclined front and back, the front or back jack 34 is started, and the adjustment method is the same as the left and right adjustment, so that the front and back horizontal deviation of the transformer 3 does not exceed 2 mm.

[0060] The two first hoops 5 are fixed on the power pole 1 by bolts, and in the fixing process, the first rotating frame 6 can rotate on one side of the longitudinal beam 7, and the first rotating frame 6 rotates outside the two first hoops 5 to adapt to the slight deformation of the support frame 2. The two second hoops 16 are fixed on the power pole 1 by bolts, and in the fixing process, the second rotating frame 17 rotates on the two second hoops 16, so that the first rotating frame 6 and the second rotating frame 17 rotate with the adjusted support frame 2.

[0061] The bottom end of the support arm 20 is moved to one side of the lower first connecting beam 25, and holes are drilled in the support arm 20 and the first connecting beam 25 using an electric drill. The drilling position needs to be accurate, and the deviation should not exceed 1 mm. After the drilling is completed, the support arm 20 and the first connecting beam 25 are fixed using M12 bolts, and the assembly of the entire installation tooling is completed. At the same time, the lifting appliance 4 can be used again.
