Description

Technical Field

[0001] This invention belongs to the field of transformer technology, specifically a suspended transformer. Background Technology

[0002] In power distribution networks, a large number of transformers are used in voltage conversion to meet the power distribution needs of different areas such as cities and rural areas. Among them, transformers installed on utility poles are key equipment at the end of the distribution network, mainly responsible for stepping down high-voltage electricity such as 10kV to low-voltage electricity of 220V / 380V to provide electricity to surrounding residents and small industrial and commercial users.

[0003] Transformer installation requires a specialized platform, which is typically a frame structure welded from angle steel or channel steel. During installation, the platform is first fixed to the pre-set height of the utility pole using clamps, bolts, and other connectors. Then, a crane is used to lift the transformer from the ground and slowly move it to the top of the platform. After the transformer is slowly placed on the platform, its horizontal position and orientation need to be adjusted so that the steel base at the bottom of the transformer is aligned with the bolt holes on the platform. Bolts are then inserted and tightened to complete the final fixing.

[0004] After the transformer is hoisted onto the platform, its position needs to be adjusted by prying and pushing to align with the base and bolt holes. Due to the transformer's large weight and the platform's height, operators find it difficult to control it precisely at close range, often requiring repeated adjustments. This not only prolongs the installation time but also increases the risks of working at height.

[0005] At the same time, when the transformer falls onto the platform, its gravity will suddenly act entirely on the platform, forming an instantaneous impact load. This impact may cause the bolts connecting the platform and the utility pole to loosen, which will reduce the structural stability in the long run and may even cause the platform to break or the transformer to fall, posing a safety hazard. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the aforementioned technical problems, this invention proposes a suspended transformer. By setting up an installation mechanism, the adjustment steps for high-altitude operations can be significantly reduced, avoiding repeated adjustments caused by the large weight of the transformer and limited operating space. The specific structure is as follows.

[0007] A suspended transformer includes a transformer body; the transformer body is mounted on two utility poles via a mounting mechanism.

[0008] The mounting mechanism includes a mounting plate; the mounting plate has two U-shaped steel sections at its top and bottom; the upper U-shaped steel section is fixedly installed at the bottom of the transformer body; the U-shaped steel sections at the top and bottom of the mounting plate are fixedly connected by bolts and nuts.

[0017] The inner wall of the worm gear has a rectangular groove, and the rectangular rods slide in the opposite rectangular grooves respectively.

[0018] In a preferred embodiment of the present invention, the side of the side compartment facing the gear cylinder is an arc surface;

[0019] The side compartment is threaded with a first locking bolt on the side closest to the gear cylinder; a second threaded groove is provided on the bottom plate of the mounting cylinder below the gear cylinder, and the first locking bolt is inserted into the second threaded groove and meshes with the second threaded groove.

[0020] In a preferred embodiment of the present invention, a second fixing plate is provided between the first fixing plate and the mounting plate;

[0021] The second fixing plate has the same structure as the first fixing plate and is mirrored; the second fixing plate is also attached to the arc plate and engages with the thread on the outer ring surface of the arc plate;

[0022] The T-shaped threaded rod passes through the through hole in the second fixed plate before being inserted into the first threaded groove.

[0023] In a preferred embodiment of the present invention, a filler plate is provided between the second fixing plate and the mounting plate;

[0024] The filler plate also has two through holes, and the T-shaped threaded rod passes through the through holes of the filler plate.

[0025] In a preferred embodiment of the present invention, the tops of both the first fixing plate and the second fixing plate are fixed with opposing semi-circular clamps.

[0026] The opposite surfaces of the semicircular clamps are threaded; the opposite semicircular clamps are fixedly connected by bolts.

[0027] As a preferred embodiment of the present invention, four notches are provided on the top end face of the mounting plate;

[0028] The four T-shaped threaded rods pass through the four notches respectively; the bottoms of the two upper U-shaped steels are fixedly connected with positioning blocks;

[0029] The bottom end face of each positioning block is an arc-shaped concave surface, the diameter of which is the same as the diameter of the T-shaped threaded rod.

[0030] In a preferred embodiment of the present invention, each of the arc-shaped plates is composed of multiple assembled plates;

[0031] The sector-shaped block is fixed to the bottom assembly plate; each assembly plate has a slot at the top; countersunk holes are provided on both sides of the slot at the ends of the assembly plate.

[0032] Except for the bottom of the lowest assembly plate, which is fixedly connected to a locking block, and the locking blocks are provided with a third threaded groove on both sides of the locking block; the locking blocks on the upper assembly plate are all locked in the locking groove.

[0033] The countersunk hole is equipped with countersunk bolts, and all countersunk bolts are engaged in the third thread groove, so that the assembly plates in the vertical direction form a whole.

[0034] In a preferred embodiment of the present invention, each of the assembly plates has a roller rotating on its inner ring surface, and the rollers are in contact with the utility pole.

[0035] In a preferred embodiment of the present invention, fixing blocks are fixedly connected to both end faces of the assembly plate;

[0036] The fixing blocks on the adjacent assembly plates are staggered and fit together vertically; the staggered fixing blocks on the adjacent assembly plates are fixedly connected by the second locking bolt, so that the assembly plates in the circumferential direction form a whole.

[0037] The fixing block did not contact the utility pole or the semi-circular groove.

[0038] The beneficial effects of this invention are as follows:

[0039] 1. The suspended transformer of the present invention first forms an integral structure with the transformer body, mounting plate and first fixing plate, and achieves smooth lifting and lowering through the drive mechanism. It does not require precise alignment at high altitude. The threaded engagement structure of the arc plate and the semi-circular groove can realize automatic guidance and positioning during the lifting process. With the tension adjustment of the T-shaped threaded rod, the mounting plate and the utility pole can be fixed quickly. This can greatly reduce the adjustment steps of high-altitude operation, avoid repeated debugging caused by the large weight of the transformer and the limited operating space, significantly shorten the installation time, and reduce the risk of high-altitude operation for operators.

[0040] 2. The suspended transformer of the present invention first forms an integral structure with the transformer body, the mounting plate, and the first fixed plate, and then achieves smooth lifting and lowering through a drive mechanism. During the entire process, the weight of the transformer is transferred to the ground layer by layer through the arc plate, the toothed cylinder, and the mounting cylinder, and the lifting speed is precisely controlled by a dual-axis motor. This avoids the instantaneous impact caused by the free fall of the transformer body in traditional hoisting, and avoids the safety hazards of loosening the bolts connecting to the utility pole due to impact, which would reduce the structural stability over time and even cause the frame to break or the transformer to fall.

[0041] 3. In the suspended transformer of the present invention, four notches are provided on the mounting plate. When the two upper U-shaped rods are placed on the mounting plate, the positioning blocks at the bottom of the U-shaped steel will be locked in the notches. When the T-shaped threaded rod is locked, and the upper and lower U-shaped steels are gradually locked by bolts, the positioning blocks will abut against the T-shaped threaded rod, thereby fixing the T-shaped threaded rod and preventing it from loosening. At the same time, since the T-shaped threaded rod is inserted into the first threaded groove of the mounting plate, and the transformer body is mounted on the mounting plate, the transformer body will exert downward pressure on the mounting plate, and the pressure borne by the mounting plate will act on the T-shaped threaded rod, thereby squeezing the T-shaped threaded rod and improving the fixing effect of the T-shaped threaded rod, preventing it from loosening. After the T-shaped threaded rod is fixed, the first fixing plate and the second fixing plate are also fixed on the arc plate, thereby preventing the first fixing plate and the second fixing plate from sliding on the arc plate.

Detailed Implementation

[0054] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0055] like Figures 1 to 10 As shown, the suspended transformer of the present invention, as an embodiment of the present invention, includes a transformer body 1; the transformer body 1 is mounted on two utility poles 11 by a mounting mechanism;

[0056] The installation mechanism includes an installation plate 2; the installation plate 2 is provided with two U-shaped steels 12 at the top and bottom; the U-shaped steel 12 located at the top is fixedly installed at the bottom of the transformer body 1; the U-shaped steels 12 located at the top and bottom of the installation plate 2 are fixedly connected by bolts and nuts;

[0057] Each utility pole 11 is equipped with a mounting cylinder 13, which is inverted T-shaped and fits against the ground; the outer ring of the mounting cylinder 13 has a toothed cylinder 14 that rotates; the surface of the toothed cylinder 14 has evenly arranged insertion holes 15, and the insertion holes 15 have threads; a separate driving mechanism is provided between the two toothed cylinders 14.

[0058] Three arc-shaped plates 3 are provided above the gear cylinder 14; each arc-shaped plate 3 has a fan-shaped block 31 fixedly connected to its bottom, and the fan-shaped block 31 is fixed to the top of the gear cylinder 14 by bolts.

[0059] The arc-shaped plate 3 extends upward around the utility pole 11; threads are provided on the outer surface of the arc-shaped plate 3.

[0060] The mounting plate 2 has a first threaded groove 21 on both ends, and the first threaded groove 21 penetrates the mounting plate 2; the two utility poles 11 have a first fixing plate 22 on opposite sides, and the first fixing plate 22 has a semi-circular groove 23 on the side facing the arc plate 3, and the semi-circular groove 23 has a thread.

[0061] The first fixing plate 22 has two through holes 24, and a T-shaped threaded rod 25 is inserted into the through holes 24, and the T-shaped threaded rod 25 is engaged in the first threaded groove 21; the semi-circular groove 23 is in contact with the arc plate 3, and the thread in the semi-circular groove 23 is engaged with the thread on the outer ring surface of the arc plate 3.

[0062] In this embodiment, the driving mechanism includes a central compartment 4; side compartments 41 are provided on both sides of the central compartment 4, and the side compartments 41 slide within the central compartment 4;

[0063] A dual-shaft motor 42 is installed inside the intermediate compartment 4; rectangular rods 43 are installed on the output shafts on both sides of the dual-shaft motor 42 via couplings;

[0064] Turbines 44 are rotatably mounted in the two side compartments 41 and mesh with the gear cylinder 14; each of the two turbines 44 is provided with a worm 45 on one side and the worm 45 rotates in the mounting seat and meshes with the turbine 44.

[0065] The inner wall of the worm gear 45 is provided with a rectangular groove, and the rectangular rods 43 slide in the opposite rectangular grooves respectively;

[0066] In this embodiment, the side of the side compartment 41 facing the gear cylinder 14 is an arc surface;

[0067] The side compartment 41 is threaded with a first locking bolt 46 on the side near the gear cylinder 14; a second threaded groove 47 is provided on the bottom plate of the mounting cylinder 13 below the gear cylinder 14, and the first locking bolt 46 is inserted into the second threaded groove 47 and meshes with the second threaded groove 47.

[0068] During implementation, when installing the transformer body 1, the distance between the two utility poles 11 is calculated based on the length of the transformer body 1. Then, the utility poles 11 are buried in the soil according to the calculated distance. During the process of burying the utility poles 11, the installation cylinder 13 is first fitted onto the utility poles 11. After the utility poles 11 are fixed, the installation cylinder 13 is in contact with the ground, and the toothed cylinder 14 rotates on the installation cylinder 13. Then, the fan-shaped blocks 31 at the bottom of the multiple arc plates 3 are placed on the toothed cylinder 14 and fixed to the toothed cylinder 14 with bolts. Then the transformer body 1 can be installed.

[0069] When installing the transformer body 1, first place the drive mechanism between the two poles 11 and pull the side chambers 41 on both sides so that the side chambers 41 gradually slide out of the middle chamber 4. When the side chambers 41 move, they will drive the turbine 44 and the worm gear 45 to move. Since the rectangular rod 43 slides in the rectangular groove inside the worm gear 45, the worm gear 45 will move along the rectangular rod 43. When the side chambers 41 move to the position of the gear cylinder 14 and the turbine 44 meshes with the gear cylinder 14, adjust the position of the first locking bolt 46 on the side chambers 41 so that the first locking bolt 46 coincides with the second thread groove 47. Then rotate the first locking bolt 46, and the first locking bolt 46 gradually rotates into the second thread groove 47, thereby fixing the side chambers 41 and locking the mounting cylinder 13 at the same time.

[0070] Specifically, the mounting plate 2 is then placed on the intermediate compartment 4, the semi-circular groove 23 on the first fixing plate 22 is aligned with the arc plate 3, and the through hole 24 on the first fixing plate 22 is aligned with the first threaded groove 21. Then, the T-shaped threaded rod 25 is inserted into the through hole 24. After passing through the through hole 24, the T-shaped threaded rod 25 will be inserted into the first threaded groove 21. Then, the T-shaped threaded rod 25 is rotated, and the T-shaped threaded rod 25 will gradually rotate into the first threaded groove 21. During the process of the T-shaped threaded rod 25 gradually rotating into the first threaded groove 21, it will gradually push the first fixing plate 22 closer to the arc plate 3, and gradually make the thread in the semi-circular groove 23 mesh with the thread on the surface of the arc plate 3. Continue to rotate the T-shaped threaded rod 25, and the T-shaped threaded rod 25 will pull the first fixing plate 22, so that the semi-circular groove 23 on the first fixing plate 22 is completely meshed with the arc plate 3.

[0071] More specifically, after the first fixing plates 22 on both sides are installed, the mounting plate 2 is confined between the two utility poles 11. Then, four U-shaped steel bars 12 are placed on the upper and lower sides of the mounting plate 2 respectively. The two U-shaped steel bars 12 at the bottom are placed on the side compartment 41. Then, the U-shaped steel bars 12 facing each other are locked and fixed with bolts and nuts. Then, the transformer body 1 is placed on the upper U-shaped steel bars 12 and locked and fixed. After the transformer body 1 is fixed, the dual-shaft motor 42 is controlled to rotate. The dual-shaft motor 42 will drive the two rectangular rods 43 to rotate at the same time. The rotating rectangular rods 43 will drive the worm gear 45 to rotate. At the same time, the worm gear 45 will drive the turbine 44 to rotate. Since the turbine 44 meshes with the teeth on the gear cylinder 14 and the side compartment 41 is fixed by the first locking bolt 46, Therefore, the turbine 44 will drive the gear cylinder 14 to rotate. Since the arc plate 3 is fixed to the gear cylinder 14 by bolts, it will drive the arc plate 3 to rotate along the utility pole 11. Since the thread in the semi-circular groove 23 meshes with the thread on the surface of the arc plate 3, it will push the first fixing plate 22 to move upward gradually. Since the gear cylinders 14 on the two utility poles 11 are driven at the same time, they will drive the two first fixing plates 22 to move upward at the same time. Since the mounting plate 2 is connected to the first fixing plate 22 through the T-shaped threaded rod 25, it will drive the mounting plate 2 and the transformer body 1 above the mounting plate 2 to move upward. When the transformer body 1 moves upward to the preset height, the dual-axis motor 42 is controlled to stop rotating. Then the bolt is inserted into the insertion hole 15 and the bolt is rotated so that the bolt abuts against the mounting cylinder 13, thereby fixing the gear cylinder 14.

[0072] Furthermore, once the transformer body 1 reaches the appropriate position, the first locking bolt 46 is turned out of the second threaded groove 47, and the drive mechanism is retracted; then, a rain cloth is wrapped around the arc plate 3 and the gear cylinder 14 to protect the gear cylinder 14 and the arc plate 3.

[0073] In general, by first forming an integral structure with the transformer body 1, mounting plate 2, and first fixing plate 22, the transformer body 1 can be smoothly lifted and lowered through the drive mechanism. Precise alignment at high altitudes is not required. The threaded engagement structure of the arc plate 3 and the semi-circular groove 23 can achieve automatic guidance and positioning during the lifting process. With the tension adjustment of the T-shaped threaded rod, the mounting plate 2 and the utility pole 11 can be fixed quickly. This can significantly reduce the adjustment steps in high-altitude operations, avoid repeated debugging caused by the large weight of the transformer and the limited operating space, significantly shorten the installation time, and reduce the risk of high-altitude operations for operators.

[0074] Meanwhile, by first forming an integral structure with the transformer body 1, mounting plate 2, and first fixing plate 22, the transformer body 1 is lifted and lowered smoothly through the drive mechanism. During the entire process, the weight of the transformer is transferred to the ground layer by layer through the arc plate 3, toothed cylinder 14, and mounting cylinder 13. The lifting speed is precisely controlled by the dual-axis motor 42, which avoids the instantaneous impact caused by the free fall of the transformer body 1 in traditional hoisting. This avoids the loosening of the connecting bolts with the utility pole 11 due to the impact, which would reduce the structural stability over time and even cause the safety hazard of the platform breaking and the transformer falling.

[0075] As an embodiment of the present invention; a second fixing plate 26 is provided between the first fixing plate 22 and the mounting plate 2;

[0076] The second fixing plate 26 has the same structure as the first fixing plate 22 and is mirrored; the second fixing plate 26 is also attached to the arc plate 3 and engages with the thread on the outer ring surface of the arc plate 3;

[0077] The T-shaped threaded rod 25 passes through the through hole 24 in the second fixing plate 26 before being inserted into the first threaded groove 21;

[0078] In this embodiment, a filler plate 27 is provided between the second fixing plate 26 and the mounting plate 2;

[0079] The filling plate 27 also has two through holes 24, and the T-shaped threaded rod 25 passes through the through holes 24 of the filling plate 27.

[0080] During implementation, since the second fixing plate 26 has the same structure as the first fixing plate 22 and is mirrored, when installing the first fixing plate 22, the first fixing plate 22 and the second fixing plate 26 are respectively attached to the arc plate 3, and the first fixing plate 22 and the second fixing plate 26 are attached to each other, and the arc plate 3 is located inside the first fixing plate 22 and the second fixing plate 26. Then, according to the distance between the second fixing plate 26 and the mounting plate 2, a filler plate 27 of corresponding width is added, and the T-shaped threaded rod 25 passes through the through hole 24 in the first fixing plate 22, the second fixing plate 26 and the filler plate 27 in sequence, so that the T-shaped threaded rod 25 is engaged in the first threaded groove 21.

[0081] As the T-shaped threaded rod 25 gradually rotates into the first threaded groove 21, the filler block gradually contacts the mounting plate 2, and then contacts the second fixing plate 26. After the T-shaped threaded rod 25 is locked, the mounting plate 2, the filler plate 27, and the second fixing plate 26 abut against each other, thereby bringing the second fixing plate 26 into contact with the first fixing plate 22. The threads in the semi-circular groove 23 on the second fixing plate 26 engage with the threads on the surface of the arc plate 3, thereby increasing the thread contact area with the arc plate 3 and improving the fixing effect between the first fixing plate 22, the second fixing plate 26, and the arc plate 3. This prevents the first fixing plate 22 and the second fixing plate 26 from sliding downward. At the same time, since both utility poles 11 are engaged with the arc plate 3 through the first fixing plate 22 and the second fixing plate 26, the mounting plate 2, the first fixing plate 22, and the second fixing plate 26 form an integral frame, thereby further improving the support effect on the mounting plate 2.

[0082] As an embodiment of the present invention, the tops of the first fixing plate 22 and the second fixing plate 26 are both fixed with opposing semi-circular clamps 28;

[0083] The opposite surface of the semi-circular clamp 28 is threaded; the opposite semi-circular clamps 28 are fixedly connected by bolts;

[0084] In this embodiment, four notches 29 are provided on the top end face of the mounting plate 2;

[0085] The four T-shaped threaded rods 25 pass through the four notches 29 respectively; the bottoms of the two upper U-shaped steels 12 are fixedly connected with positioning blocks 16;

[0086] The bottom end face of each positioning block 16 is an arc-shaped concave surface, the diameter of which is the same as the diameter of the T-shaped threaded rod 25;

[0087] During implementation, since semi-circular clamps 28 are fixedly connected to the top of both the first fixing plate 22 and the second fixing plate 26, after the first fixing plate 22 and the second fixing plate 26 are moved to the appropriate position, the two opposing semi-circular clamps 28 are locked and fixed with bolts. Since the opposing semi-circular clamps 28 can be locked onto the arc plate 3, and since the opposing side of the semi-circular clamps 28 is threaded, when the semi-circular clamps 28 are locked, the meshing area with the threads on the surface of the arc plate 3 can be further increased, thereby further improving the fixing effect on the first fixing plate 22, the second fixing plate 26 and the mounting plate 2.

[0088] Because the mounting plate 2 has four notches 29, when the two upper U-shaped rods are placed on the mounting plate 2, the positioning block 16 at the bottom of the U-shaped steel 12 will be locked in the notch 29. When the T-shaped threaded rod 25 is locked, and the upper and lower U-shaped steel 12s are gradually locked by bolts, the positioning block 16 will abut against the T-shaped threaded rod 25, thereby fixing the T-shaped threaded rod 25 and preventing it from becoming loose. At the same time, because the T-shaped threaded rod 25 is inserted into the first threaded groove 21 of the mounting plate 2, and the transformer body... 1. The transformer body 1 is installed on the mounting plate 2. Therefore, the transformer body 1 will apply downward pressure to the mounting plate 2, and the pressure on the mounting plate 2 will act on the T-shaped threaded rod 25, thereby squeezing the T-shaped threaded rod 25, improving the fixing effect of the T-shaped threaded rod 25, and preventing the T-shaped threaded rod 25 from becoming loose. After the T-shaped threaded rod 25 is fixed, the first fixing plate 22 and the second fixing plate 26 are also fixed on the arc plate 3, thereby preventing the first fixing plate 22 and the second fixing plate 26 from sliding on the arc plate 3.

[0089] As one embodiment of the present invention; each of the arc-shaped plates 3 is composed of a plurality of assembled plates 32;

[0090] The sector-shaped block 31 is fixed on the bottom assembly plate 32; each assembly plate 32 has a slot 33 on its top; countersunk holes are provided on both sides of the slot 33 at the ends of both sides of the assembly plate 32.

[0091] Except for the bottom of the lowest assembly plate 32, which is fixedly connected to the bottom of each of the plates, and the ends of the two sides of the plate 34 are provided with third threaded grooves 35; the plates 34 on the upper assembly plate 32 are all locked in the grooves 33.

[0092] The countersunk hole is provided with countersunk bolts 36, and all countersunk bolts 36 are engaged in the third thread groove 35, so that the assembly plate 32 in the vertical direction forms a whole.

[0093] In this embodiment, each of the assembly plates 32 has a roller rotating on its inner ring surface, and the rollers are all in contact with the utility pole 11;

[0094] In this embodiment, fixing blocks 37 are fixedly connected to both end faces of the assembly plate 32;

[0095] The fixing blocks 37 on the two adjacent assembly plates 32 are staggered and fit together vertically; the fixing blocks 37 on the two adjacent assembly plates 32 are fixedly connected by the second locking bolts 38, so that the assembly plates 32 in the circumferential direction form a whole.

[0096] The fixing block 37 did not contact the utility pole 11 and the semi-circular groove 23;

[0097] In practice, since the arc plate 3 is composed of multiple assembly plates 32, and the locking block 34 at the bottom of the upper assembly plate 32 is inserted into the locking groove 33 at the top of the lower assembly plate 32, and the upper and lower adjacent assembly plates 32 are fixed by countersunk bolts 36, and the countersunk bolts 36 are located in the countersunk holes, arc plates 3 of different lengths can be assembled according to the installation height of the transformer body 1, thereby avoiding the fact that the length of the arc plate 3 is fixed and cannot be adjusted according to the installation height of the transformer body 1. At the same time, the fixed length arc plate 3 is also extremely inconvenient to transport.

[0098] Specifically, since there are staggered fixing blocks 37 fixed between adjacent assembly plates 32, after the assembly plate 32 is installed above the toothed cylinder 14 and the fixing blocks 37 are staggered, the adjacent fixing blocks 37 are then locked and fixed by the second locking bolt 38, so that the adjacent assembly plates 32 can form a whole. Then the upper assembly plates 32 are assembled in sequence and fixed by countersunk bolts 36, so that multiple arc plates 3 can form a whole.

[0099] Because the inner ring of the assembly plate 32 has rollers, the friction between the arc plate 3 and the utility pole 11 can be reduced when the arc plate 3 rotates along the utility pole 11.
