Description

Technical Field

[0001] This invention relates to the field of transformer installation technology, specifically to a DC converter transformer mounting bracket and installation method. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Transformers are one of the core pieces of equipment in power grids. Along urban roadsides, transformers are often mounted on double-pole transformer mounting brackets. These brackets are H-shaped, with the transformer installed between two uprights. The structure of the mounting bracket itself has a significant impact on the secure installation of the transformer and is crucial for its long-term stable operation.

[0003] Traditional support brackets mostly employ a fixed structure, requiring external hoisting equipment for movement. Furthermore, precise angle adjustment is difficult when positioning them near utility poles, resulting in low installation efficiency. While some movable brackets achieve short-distance movement via casters, additional ground anchors or expansion bolts are needed for fixing, making the process complex and potentially damaging to the utility pole surface. Therefore, this invention proposes a DC converter transformer mounting bracket. Summary of the Invention

[0004] The purpose of this invention is to provide a DC converter transformer mounting bracket and installation method to solve the problems mentioned in the background art, which are mostly fixed structures, requiring external hoisting equipment for movement, and are difficult to accurately adjust the angle when positioned near utility poles, resulting in low installation efficiency. Although some movable brackets can move short distances via casters, additional ground anchors or expansion bolts are required for fixing, which is complicated and can easily damage the surface of the utility pole.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A DC converter transformer mounting bracket includes a mounting frame. The mounting frame has symmetrically arranged movable components at both ends for moving the bracket. Fixed components are located inside the movable components on both sides. The fixed components are vertically movable relative to the ends of the mounting frame via the movable components for connection and fixation to a utility pole. Two opposing mounting beams are slidably connected to the top of the mounting frame. A transformer is fixedly connected to the top ends of the two mounting beams by bolts. An adjustment mechanism acting on the mounting beams is also provided in the middle of the mounting frame. The adjustment mechanism includes an adjustment component and an auxiliary component. The adjustment component adjusts the distance between the two opposing mounting beams, and the auxiliary component assists in the linear movement of the two mounting beams.

[0007] Optionally, the movable component includes a support rod, a mounting sleeve, a support column, a first fastening rod, and a movable wheel. The mounting sleeve is disposed on the front and rear sides of the end of the mounting frame. Support rods are provided on both sides of the mounting sleeve. The support column is movably connected to both ends of the support rod. The top of the support column is provided with a first fastening rod for pressing against the support rod. Movable wheels are provided at the bottom of both sides of the support column to facilitate the movement of the bracket.

[0008] Optionally, the fixing component includes a fixing rod disposed between the front and rear support columns. Opposite arc-shaped plates are slidably connected to both sides of the fixing rod. A square hole is opened on the outer side of the arc-shaped plate, and a limiting rod is installed on the square hole. A fixing plate that contacts the utility pole is connected to one end of the limiting rod facing the inner side of the arc-shaped plate. A spring is also inserted through the limiting rod.

[0009] Optionally, the arc-shaped plate slides on one end of the fixed rod and is limited and fixed by the second fastening rod. One end of the second fastening rod is pressed against the fixed rod by a knob, and the other end plates of the arc-shaped plates on both sides are fixedly connected by locking bolts.

[0010] Optionally, the fixing plate is arc-shaped and made of hard rubber.

[0011] Optionally, the adjustment assembly includes an adjustment box installed in the middle of the mounting frame. The adjustment box has an adjustment cavity inside, and a bidirectional lead screw is installed in the adjustment cavity. An adjustment rod is rotatably connected to the top of the adjustment box. The lower end of the adjustment rod passes through the adjustment cavity and is fixedly connected to a main bevel gear. A driven bevel gear is meshed with the lower side of the main bevel gear, and the driven bevel gear is fixedly connected to the middle of the bidirectional lead screw.

[0012] Optionally, the two sides of the bidirectional lead screw are connected to moving parts by opposing threads, the bottom of the moving parts is connected to an L-shaped rod, and the other end of the L-shaped rod extends through to the outside of the adjustment box and is connected to a connecting plate. The connecting plate is set at the bottom of the mounting beam.

[0013] Optionally, the auxiliary component includes a fixing lug correspondingly disposed inside the mounting bracket, a guide rod is installed between the fixing lugs, sliding sleeves are slidably connected to the outer sides of the guide rods, a connecting rod is fixedly connected to the outer side of the sliding sleeves, and the other end of the connecting rod is fixedly connected to the side of the L-shaped rod.

[0014] Optionally, the mounting bracket, moving assembly, fixing assembly, and mounting beam are all made of high-strength alloy steel.

[0015] A method for installing a DC converter transformer mounting bracket, comprising:

[0016] S1: First, insert the support rods of the two movable components into the mounting sleeves at the ends of the mounting bracket to fix the relative positions of the support column and the support rod and prevent the support column from sliding. At this time, the movable component only serves as a moving carrier and moves to the target installation position by means of the moving wheels.

[0017] S2: When the bracket is pushed directly under the utility pole, rotate the first fastening rod at the top of the support column to loosen it and release the fixation of the support column. Using the end of the mounting bracket as a fulcrum, lift the support column upwards so that the moving components on both sides rotate 90° vertically around the support column until the support column is perpendicular to the axis of the utility pole, that is, the moving components are lifted off the ground. Then tighten the first fastening rod again to lock the relative position of the support column and the support rod to ensure the stability of the moving components.

[0018] S3: Loosen the second fastening rod at one end of the arc-shaped plate, slide the arc-shaped plates on both sides along the fixing rod until the distance between them is slightly larger than the diameter of the utility pole, push the limiting rod towards the utility pole to compress the spring, and the arc-shaped fixing plate made of hard rubber will initially contact the surface of the utility pole. Continue to slide the arc-shaped plate so that the two fixing plates on both sides are symmetrically attached to the surface of the utility pole. Tighten the second fastening rod, press the fixing rod with the knob to lock the position of the arc-shaped plate, and tighten the other end of the two arc-shaped plates with the locking bolt to form a closed ring structure. The limiting rod is connected to the fixing plate through the spring to form an elastic buffer structure. When the utility pole is subjected to external force, the elastic deformation of the spring can absorb part of the impact force, reduce the rigid collision between the fixing component and the utility pole, and thus reduce the risk of loosening or damage to the connection. Moreover, the elastic characteristics of the spring allow the limiting rod to automatically adjust its position according to the actual diameter of the utility pole. When the diameter of the utility pole changes, the spring moves the limiting rod by extension and retraction, so that the fixing plate always keeps in close contact with the utility pole, thereby simplifying the installation process, eliminating the need to customize fixing components for different specifications of utility poles, and improving versatility and installation efficiency.

[0019] S4: Based on the transformer specifications, the main bevel gear is driven to rotate by rotating the adjusting rod. Due to the meshing transmission between the main bevel gear and the driven bevel gear, the driven bevel gear drives the bidirectional lead screw to rotate, and then the moving parts on both sides of the bidirectional lead screw move in opposite directions. Through the L-shaped rod and the connecting plate, the mounting beam moves synchronously closer. When the mounting beam moves, the sliding sleeve slides linearly along the guide rod. Through the linkage between the connecting rod and the L-shaped rod, it is ensured that the mounting beam moves parallel without deviation. After adjusting the spacing of the mounting beams to match the mounting holes at the bottom of the transformer, the transformer is fixed to the top of the mounting beam with bolts, thereby achieving precise and synchronous adjustment of the mounting beam spacing to meet the installation requirements of various transformer specifications.

[0020] The beneficial effects of this invention are:

[0021] 1. In this invention, in the mobile mode, the mobile component acts as a mobile carrier, and the support can be easily moved to the target installation position via the mobile wheels. After the support is moved to the bottom of the utility pole, the support column is lifted upwards using the end of the mounting bracket as a fulcrum, driving the support rod to rotate within the mounting sleeve until the support column is perpendicular to the axis of the utility pole. At this point, the mobile wheels are lifted off the ground, and the side of the support column is in contact with the surface of the utility pole. Then, the first fastening rod is rotated in the opposite direction so that its end is pressed against the support rod, locking the relative angle between the support column and the support rod. This allows the mobile mode to be quickly switched to the fixed mode, thereby fixing the utility pole to the fixed connection via the fixed component. The vertical rotation switching mode simplifies the installation process, eliminating the need for complex operating steps and additional fixing devices, greatly shortening the installation time, and effectively improving installation efficiency and quality.

[0022] 2. In this invention, the adjustment mechanism, through mechanical synchronous transmission, ensures the precision and consistency of the movement of the two mounting beams, enabling rapid and accurate adjustment of the beam spacing to match the mounting holes at the bottom of the transformer. Simultaneously, the guide rod in the auxiliary assembly provides linear guidance for the sliding sleeve. The sliding sleeve is fixedly connected to the side of the L-shaped rod via a connecting rod. When the L-shaped rod moves, the sliding sleeve slides synchronously along the guide rod, eliminating any tendency for the mounting beams to shift or twist, further ensuring the parallelism of the two mounting beams. Through this precise and synchronous adjustment method, the mounting bracket can adapt to the installation requirements of transformers of various specifications, improving its versatility and applicability.

[0039] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0040] Example 1:

[0041] As attached Figure 1 To be continued Figure 9 As shown, the present invention provides a DC converter transformer mounting bracket, including a mounting frame 1. The mounting frame 1 has symmetrically arranged moving components 2 at both ends for moving the bracket. Fixed components 3 are arranged inside the moving components 2 on both sides. The fixed components 3 are vertically movable about the ends of the mounting frame 1 via the moving components 2 for connection and fixation to a utility pole. Two opposing mounting beams 4 are slidably connected to the top of the mounting frame 1. A transformer 6 is fixedly connected to the top of the two mounting beams 4 by bolts. An adjustment mechanism 5 acting on the mounting beams 4 is also provided in the middle of the mounting frame 1. The adjustment mechanism 5 includes an adjustment component and an auxiliary component. The adjustment component is used to adjust the distance between the two opposing mounting beams 4, and the auxiliary component is used to assist the linear movement of the two mounting beams 4.

[0042] Mounting bracket 1, moving component 2, fixed component 3, and mounting beam 4 are all made of high-strength alloy steel.

[0043] Example 2:

[0044] As attached Figure 4 To be continued Figure 6 As shown, this embodiment is basically the same as the previous embodiment, except that the movable component 2 includes a support rod 201, a mounting sleeve 202, a support column 203, a first fastening rod 204, and a movable wheel 205. The mounting sleeve 202 is disposed on the front and rear sides of the end of the mounting frame 1. The support rod 201 is provided on both sides of the mounting sleeve 202. The support column 203 is movably connected to both ends of the support rod 201. The top of the support column 203 is provided with a first fastening rod 204 for pressing against the support rod 201. The bottom of both sides of the support column 203 is provided with a movable wheel 205 to facilitate the movement of the bracket.

[0045] The fixing component 3 includes a fixing rod 301 disposed between the front and rear support columns 203. The two sides of the fixing rod 301 are slidably connected to opposing arc plates 302. The outer side of the arc plate 302 is provided with a square hole 303, and a limiting rod 304 is installed on the square hole 303. The end of the limiting rod 304 facing the inner side of the arc plate 302 is connected to a fixing plate 306 that contacts the utility pole. A spring 305 is also provided through the limiting rod 304.

[0046] The arc plate 302 slides on one end of the fixed rod 301 and is limited and fixed by the second fastening rod 307. One end of the second fastening rod 307 is pressed against the fixed rod 301 by a knob, and the other end plates of the arc plates 302 on both sides are fixedly connected by locking bolts 308.

[0047] The fixing plate 306 is curved and made of hard rubber.

[0048] As can be seen from the above, when the bracket is moved to the bottom of the utility pole via the moving component 2 in the moving mode, the support column 203 is lifted upwards using the end of the mounting bracket 1 as the fulcrum, driving the support rod 201 to rotate within the mounting sleeve 202 until the support column 203 is perpendicular to the axis of the utility pole. At this time, the moving wheel 205 is lifted off the ground, the side of the support column 203 is in contact with the surface of the utility pole, and the first fastening rod 204 is rotated in the opposite direction so that its end is pressed against the support rod 201, locking the relative angle between the support column 203 and the support rod 201, ensuring the structural rigidity in the fixed mode. Then, the arc-shaped plates 302 on both sides of the fixed rod 301 can slide along the fixed rod 301, and the spacing is initially adjusted by the second fastening rod 307 to adapt to the diameter of the utility pole. Pushing the limiting rod 304 causes the hard rubber fixing plate 306 to contact the utility pole. The spring 305 is compressed and undergoes elastic deformation to form a buffer layer. Then, the second fastening rod 307 is tightened to lock the position of the arc plate 302, and the other end of the arc plates 302 on both sides is fastened with the locking bolt 308 to form a closed ring structure. By switching modes through vertical rotation, the installation process is simplified and the versatility and installation efficiency are improved.

[0049] Example 3:

[0050] As attached Figure 7 To be continued Figure 9 As shown, this embodiment is basically the same as the previous embodiment, except that the adjustment assembly includes an adjustment box 501 installed in the middle of the mounting frame 1. An adjustment cavity 502 is opened inside the adjustment box 501. A bidirectional lead screw 505 is installed in the adjustment cavity 502. An adjustment rod 503 is rotatably connected to the top of the adjustment box 501. The lower end of the adjustment rod 503 passes through the adjustment cavity 502 and is fixedly connected to a main bevel gear 504. A driven bevel gear 506 is meshed on the lower side of the main bevel gear 504. The driven bevel gear 506 is fixedly connected to the middle of the bidirectional lead screw 505.

[0051] The two-way lead screw 505 has opposing threaded connections to moving parts 507 on both sides. The bottom of the moving parts 507 is connected to an L-shaped rod 508. The other end of the L-shaped rod 508 extends through to the outside of the adjusting box 501 and is connected to a connecting plate 509. The connecting plate 509 is located at the bottom of the mounting beam 4.

[0052] Specifically, by rotating the adjusting rod 503 at the top of the adjusting box 501, the main bevel gear 504 at its lower end rotates accordingly. The main bevel gear 504 meshes with the driven bevel gear 506, converting the vertical rotation into horizontal rotation, driving the bidirectional lead screw 505 to rotate around its own axis. The threads on both sides of the bidirectional lead screw 505 are opposite, ensuring that the moving parts 507 on both sides move in opposite directions. The moving parts 507 transmit power to the bottom of the mounting beam 4 through the L-shaped rod 508 and the connecting plate 509, driving the two mounting beams 4 to move closer synchronously. Thus, the precise opposite movement of the two mounting beams 4 is achieved through mechanical synchronous transmission, adapting to the installation requirements of transformers 6 of different specifications.

[0053] The auxiliary components include fixed ear seats 510 correspondingly disposed inside the mounting bracket 1, guide rods 511 are installed between the fixed ear seats 510, sliding sleeves 512 are slidably connected to the outer sides of the guide rods 511, and connecting rods 513 are fixedly connected to the outer side of the sliding sleeves 512, and the other end of the connecting rods 513 is fixedly connected to the side of the L-shaped rod 508.

[0054] Specifically, the guide rod 511 between the fixed lugs 510 provides a linear guide for the sliding sleeve 512, ensuring that the sliding sleeve 512 moves only along the axial direction. The sliding sleeve 512 is fixedly connected to the side of the L-shaped rod 508 through the connecting rod 513. When the L-shaped rod 508 moves, the sliding sleeve 512 slides synchronously along the guide rod 511, eliminating the offset or torsional tendency of the mounting beam 4 and ensuring the parallelism of the mounting beams 4 on both sides.

[0055] A method for installing a DC converter transformer mounting bracket:

[0056] S1: First, insert the support rods 201 of the two movable components 2 into the mounting sleeves 202 at the end of the mounting frame 1 to fix the relative position of the support column 203 and the support rods 201, and prevent the support column 203 from sliding. At this time, the movable component 2 only serves as a moving carrier and moves to the target installation position through the moving wheels 205.

[0057] S2: When the bracket is pushed directly under the utility pole, rotate the first fastening rod 204 at the top of the support column 203 to loosen it, release the fixation on the support rod 201, and lift the support column 203 upward with the end of the mounting bracket 1 as the fulcrum, so that the two moving components 2 rotate vertically around the support rod 201 by 90° until the support column 203 is perpendicular to the axis of the utility pole, that is, the moving components 2 are lifted off the ground. Then tighten the first fastening rod 204 again to lock the relative position of the support column 203 and the support rod 201, and ensure that the shape of the moving components 2 is stable.

[0058] S3: Loosen the second fastening rod 307 at one end of the arc-shaped plate 302, slide the arc-shaped plates 302 on both sides along the fixing rod 301 so that the distance between them is slightly larger than the diameter of the utility pole, push the limiting rod 304 toward the utility pole to compress the spring 305, and the arc-shaped fixing plate 306 made of hard rubber initially contacts the surface of the utility pole. Continue to slide the arc-shaped plate 302 so that the fixing plates 306 on both sides symmetrically fit the surface of the utility pole. Tighten the second fastening rod 307, and use the knob to press against the fixing rod 301 to lock the position of the arc-shaped plate 302. Tighten the other end of the arc-shaped plates 302 on both sides with the locking bolt 308 to form a closed loop structure, wherein the limiting rod 304 is connected by the spring. 305 is connected to the fixing plate 306 to form an elastic buffer structure. When the utility pole is subjected to external force, the elastic deformation of the spring 305 can absorb part of the impact force, reduce the rigid collision between the fixing component 3 and the utility pole, thereby reducing the risk of loosening or damage to the connection. In addition, the elastic characteristics of the spring 305 enable the limiting rod 304 to automatically adjust its position according to the actual diameter of the utility pole. When the diameter of the utility pole changes, the spring 305 drives the limiting rod 304 to move through extension and retraction, so that the fixing plate 306 always keeps in close contact with the utility pole, thereby simplifying the installation process. There is no need to customize the fixing component 3 for different specifications of utility poles, which improves versatility and installation efficiency.

[0059] S4: According to the specifications of transformer 6, the main bevel gear 504 is driven to rotate by rotating the adjusting rod 503. Due to the meshing transmission between the main bevel gear 504 and the driven bevel gear 506, the driven bevel gear 506 drives the bidirectional lead screw 505 to rotate. Then, the moving parts 507 on both sides of the bidirectional lead screw 505 move in opposite directions. Through the L-shaped rod 508 and the connecting plate 509, the mounting beam 4 moves synchronously closer. When the mounting beam 4 moves, the sliding sleeve 512 slides linearly along the guide rod 511. Through the linkage between the connecting rod 513 and the L-shaped rod 508, it is ensured that the mounting beam 4 moves parallel without deviation. After adjusting the spacing of the mounting beam 4 to match the mounting hole at the bottom of the transformer 6, the transformer 6 is fixed to the top of the mounting beam 4 with bolts. This achieves precise and synchronous adjustment of the spacing of the mounting beam 4, adapting to the installation requirements of various specifications of transformer 6.

S3: Loosen the second fastening rod (307) at one end of the arc plate (302), slide the arc plates (302) on both sides along the fixing rod (301) so that the distance between them is slightly larger than the diameter of the utility pole, push the limiting rod (304) toward the utility pole so that the spring (305) is compressed, and the arc fixing plate (306) of hard rubber material initially contacts the surface of the utility pole. Continue to slide the arc plate (302) so that the fixing plates (306) on both sides are symmetrically attached to the surface of the utility pole. Tighten the second fastening rod (307), press the fixing rod (301) with the knob to lock the position of the arc plate (302), and use the locking bolt (308) to tighten the other end of the arc plates (302) on both sides to form a closed ring structure, in which the limiting rod (304) is... 04) The spring (305) is connected to the fixing plate (306) to form an elastic buffer structure. When the pole is subjected to external force, the elastic deformation of the spring (305) can absorb part of the impact force, reduce the rigid collision between the fixing component (3) and the pole, thereby reducing the risk of loose connection or damage. The elastic characteristics of the spring (305) enable the limiting rod (304) to automatically adjust its position according to the actual diameter of the pole. When the diameter of the pole changes, the spring (305) drives the limiting rod (304) to move by extension and retraction, so that the fixing plate (306) always keeps in close contact with the pole, thereby simplifying the installation process. There is no need to customize fixing components for poles of different specifications, which improves versatility and installation efficiency. S4: According to the specifications of the transformer (6), the main bevel gear (504) is driven to rotate by rotating the adjusting rod (503). Due to the meshing transmission between the main bevel gear (504) and the driven bevel gear (506), the driven bevel gear (506) drives the double-acting screw (505) to rotate. Then, the moving parts (507) on both sides of the double-acting screw (505) move in opposite directions. The L-shaped rod (508) and the connecting plate (509) drive the mounting beam (4) to move closer synchronously. When the mounting beam (4) moves, the sliding sleeve (512) slides linearly along the guide rod (511). The connecting rod (513) is linked with the L-shaped rod (508) to ensure that the mounting beam (4) moves parallel without deviation. After adjusting the spacing of the mounting beam (4) to match the mounting hole at the bottom of the transformer (6), the transformer (6) is fixed to the top of the mounting beam (4) with bolts. This achieves precise and synchronous adjustment of the spacing of the mounting beam (4) to meet the installation requirements of various specifications of transformer (6).
