Description

Technical Field

[0001] This invention relates to the field of transformer rectifier assembly technology, and in particular to a transformer rectifier output rod. Background Technology

[0002] Nowadays, transformer rectifiers are commonly used in power engineering. They are mainly used in large and medium-sized aircraft that use AC power. A typical transformer rectifier is a combination of a transformer and a rectifier. To facilitate the power output of the transformer rectifier, the power lines are usually supported.

[0003] Chinese patent document CN114293836A discloses a quick-installation transformer rectifier output rod. This quick-installation transformer rectifier output rod includes a main body; a fixing block is fixedly installed on the outer side of the main body; a belt is fixedly installed on the outer side of the fixing block; a slot is formed on the inner side of the fixing block; a locking component is provided on the outer side of the fixing block; and a fixing seat is fixedly installed on the outer side of the main body. The quick-installation transformer rectifier output rod only requires inserting the belt along the slot, fixing the belt's position using the locking component, and then adjusting the angle of the equipment by rotating the support rod along the fixing seat using an adjustment component. However, in actual use, since transformer rectifier output rods often do not require frequent replacement and are used continuously for several years or even longer, the belt material will age and deform over time, causing the installation structure to become loose and unstable, posing a safety hazard.

[0004] Therefore, in view of the above problems, there is a need to provide a transformer rectifier output rod that is suitable for long-term use and has a robust structure. Summary of the Invention

[0005] The main objective of this invention is to provide a transformer rectifier output rod that can effectively solve the problem of structural instability of transformer rectifier output rods in the prior art during long-term use.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

A limiting groove is opened at the upper end of each of the two rectangular rods, and a locking mechanism is provided inside each limiting groove.

[0009] Preferably, the limiting plate is V-shaped, and a fixing threaded hole is provided in the middle of the limiting plate. Multiple left-right symmetrical limiting steel balls are provided on the two sides inside the included angle of the limiting plate. A positioning device is fixedly connected to the side of the lower end of the rectangular rod away from the positioning threaded hole.

[0010] Preferably, the limiting groove includes a straight groove with an inverted T-shaped outline. A rectangular groove is formed at the end of the straight groove away from the positioning threaded hole. A retaining groove is formed at the end of the rectangular groove away from the straight groove. A spring positioning groove is formed at the end of the retaining groove away from the rectangular groove. Multiple symmetrical L-shaped grooves are formed on the left and right sides of the straight groove. A passage groove is formed at the lower end of the multiple L-shaped grooves on both sides. A side slot is formed on the side of the passage groove away from the limiting plate.

[0011] Preferably, a limiting piece is provided in each of the slots on both sides, and a thrust spring is provided in each of the spring positioning slots on both sides.

[0012] Preferably, the positioning device includes a sliding positioning block, the sliding positioning block is inverted T-shaped, and the outline of the sliding positioning block corresponds to the outline of the straight groove. The front-to-back length of the sliding positioning block is less than the front-to-back length of the rectangular groove. Multiple mutually symmetrical triangular grooves are opened on both the left and right sides of the sliding positioning block.

[0013] In the two adjacent limiting mechanisms, the positioning device on the upper side is located in the limiting groove on the lower side.

[0014] Preferably, the locking mechanism includes two sets of symmetrical limiting blocks on the left and right sides. Each set of limiting blocks includes multiple limiting blocks in a linear array. Each limiting block consists of two parts: the upper part of the limiting block is trapezoidal and located inside the corresponding L-shaped groove; the lower part of the limiting block is rectangular and located inside the passage groove. A rotating connecting plate is fixedly connected to the lower end of each of the multiple limiting blocks, and the rotating connecting plates on the left and right sides are symmetrical. A control shaft is provided at the end of each of the two rotating connecting plates that are close to each other. The front and rear ends of the control shaft are rotatably connected to the interior of the passage groove. A set of gear teeth is provided on the side of the two control shafts that are close to each other, and the two sets of gear teeth mesh.

[0015] Preferably, a limiting spring is fixedly connected to the side of each of the limiting blocks that are far apart from each other, and the end of the limiting spring that is far away from the limiting block is fixedly connected to the inner wall of the corresponding L-shaped groove.

[0016] Preferably, the lower end of the limiting block on the same side as the side slot is provided with a release handle, and the end of the release handle near the limiting block is also fixedly connected to the rotating connecting plate, and the end of the release handle away from the limiting block passes through the side slot.

[0017] Preferably, the fixing mechanism includes a positioning bolt, the fixing threaded hole on the same side is threadedly connected to the corresponding positioning bolt, and the outer wall of the positioning bolt is also provided with a plurality of positioning nuts, the positioning nuts being located between the upper and lower fixing threaded holes on the same side.

[0018] Preferably, the cable outlet mechanism includes a mounting plate with multiple symmetrical mounting holes on both sides. Each mounting hole is fixedly connected to a corresponding positioning threaded hole by bolts.

Adjustable bolts are provided at the rotation axis of the limiting blocks and the rotating plate. Multiple cable protectors are provided at the upper end of the rotating plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. During installation, the rectifier output rod of this transformer is pushed open by the sliding positioning block, which pushes open the limit blocks and limit springs on both sides. The limit springs will push back the limit blocks into the triangular grooves corresponding to the contour, restricting the position of the sliding positioning block so that it cannot be pushed back. At this time, it can only be pushed towards the installation rod until it reaches the limit position. The limit steel balls on both sides lock the installation rod, which makes the output rod easy to install and improves the efficiency of the workers. At the same time, the fixing mechanism is installed between multiple limit mechanisms, which improves the structural stability of the output rod, makes it easy to use for a long time without aging, improves the service life of the output rod, and also improves the safety of the equipment and eliminates some safety hazards.

[0021] 2. The rectifier output rod of this transformer can be disassembled by manually opening the release handle, which pushes the rotating connecting plate on one side, causing the two meshing control shafts to rotate in the corresponding directions. The two sets of limit blocks on the upper side will open to both sides, allowing the positioning device to be removed and the corresponding limit mechanism to be disassembled. This makes the output rod easier to disassemble and improves the efficiency of the disassembly process.

[0022] 3. During installation, the output rod of this transformer rectifier is simultaneously locked by two V-shaped limiting plates, making it suitable for installation on rods of different diameters. At the same time, the angle difference between the rotating plate and the mounting plate can be adjusted by loosening the adjustable bolts to adapt to different installation requirements, thus increasing the adaptability and practicality of this output rod.

[0035] 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.

[0036] Example 1

[0037] like Figure 1-2 As shown, this embodiment discloses a transformer rectifier output pole, including a mounting pole 1, which is the pole at the installation location of this device. The outer wall of the mounting pole 1 is provided with multiple limiting mechanisms 4. The multiple limiting mechanisms 4 are combined together to fix its position with the mounting pole 1. The upper and lower adjacent limiting mechanisms 4 are staggered. The middle of the limiting mechanisms 4 on the same side is provided with a vertically penetrating fixing mechanism 3, which is used to lock the multiple adjacent limiting mechanisms 4 after installation. The rear ends of the multiple limiting mechanisms 4 on the rear side are fixedly connected to an output mechanism 2. The cable protector 26 at the upper end of the output mechanism 2 is used to connect the wire and support it.

[0038] Specifically, such as Figure 3-5As shown, the limiting mechanism 4 includes a limiting plate 42. The overall outline of the limiting plate 42 is V-shaped. The structure of two V-shaped angles combined together can hold a cylinder of any diameter. A fixing threaded hole 421 is opened in the middle of the limiting plate 42 for installation with the positioning bolt 31. Multiple symmetrical limiting steel balls 43 are provided on the two sides inside the included angle of the limiting plate 42. When the limiting plate 42 is attached to the outer wall of the mounting rod 1 and not yet locked, the position of the limiting mechanism 4 can be easily adjusted up and down. When locked, it will reduce the force-bearing area of ​​the contact surface, increase the pressure, and further improve the degree of locking. A rectangular rod 41 is fixedly installed on both the left and right sides of the limiting plate 42, and multiple rods are connected to the cable outlet machine. A positioning threaded hole 411 is provided at one end of the rectangular rod 41 connected to the cable outlet mechanism 2, which corresponds to the position of the mounting plate 21 and is used to cooperate with the mounting plate 21 for installation. A positioning device 45 is fixedly connected to the lower end of the rectangular rod 41 away from the positioning threaded hole 411. A limiting groove 44 is provided at the upper end of both rectangular rods 41. The outline of the limiting groove 44 corresponds to the positioning device 45. In the two adjacent limiting mechanisms 4, the upper positioning device 45 is located in the lower limiting groove 44. A locking mechanism 46 is provided inside each limiting groove 44. The locking mechanism 46 can lock the positioning device 45 located in the limiting groove 44 on the same side.

[0039] Furthermore, such as Figure 6-7The limiting groove 44 includes a straight groove 441, the outline of which is inverted T-shaped. The outline of the straight groove 441 is consistent with the outline of the sliding positioning block 451. When installing this cable outlet rod, the positioning device 45 in the upper limiting mechanism 4 is located in the lower straight groove 441. A rectangular groove 442 is provided at the end of the straight groove 441 away from the positioning threaded hole 411. The front-to-back length of the sliding positioning block 451 is less than the front-to-back length of the rectangular groove 442. When installing this cable outlet rod, the sliding positioning block 451 is inserted into the straight groove 441 from the rectangular groove 442, and then pushed towards the direction of the installation rod 1 to adjust its position. A retaining groove 443 is provided at the end of the rectangular groove 442 away from the straight groove 441. A limiting piece 47 is inserted into the retaining groove 443 to constrain the thrust spring 48. The retaining groove 443 is located at the end of the rectangular groove 442 away from the straight groove 441. A spring positioning groove 444 is provided at one end, and a thrust spring 48 is fixedly installed in the spring positioning groove 444. Before installation, the thrust spring 48 is in a compressed state. When the sliding positioning block 451 is inserted into the straight groove 441 from the rectangular groove 442, the limiting piece 47 needs to be pulled out, so that the thrust spring 48 can lose its constraint and release its elastic force, pushing the positioning device 45 towards the mounting rod 1. Multiple symmetrical L-shaped grooves 445 are provided on the left and right sides of the straight groove 441. The L-shaped grooves 445 are used to position the limiting block 461. The lower ends of the multiple L-shaped grooves 445 on both sides are provided with a passage groove 446, which corresponds to the position of the rotating connecting plate 463 and the control shaft 464. A side groove 447 is provided on the side of the passage groove 446 away from the limiting plate 42, so that the release handle 465 can pass through.

[0040] In order to stably install the positioning device 45 in the limiting groove 44, such as Figure 8-10As shown, the sliding positioning block 451 has multiple symmetrical triangular grooves 452 on both its left and right sides. The locking mechanism 46 includes two sets of symmetrical limiting blocks 461 on the left and right sides. Each set of limiting blocks 461 includes multiple linear arrays of limiting blocks 461. Each limiting block 461 consists of two parts, upper and lower. The upper part of the limiting block 461 is trapezoidal, corresponding to the contour of the triangular groove 452. A limiting spring 462 is fixedly connected to the side of each limiting block 461 that is far away from the limiting block 461. The end of the limiting spring 462 that is far away from the limiting block 461 is fixedly connected to the inner wall of the corresponding L-shaped groove 445. The upper part of the limiting block 461 is located in the corresponding L-shaped groove 445. Inside 5, the lower part of the limiting block 461 is rectangular and located inside the passage groove 446. When the sliding positioning block 451 pushes through the straight groove 441, the sliding positioning block 451 will push away the limiting blocks 461 and the limiting spring 462 on both sides. When the limiting block 461 that has just been pushed corresponds to the position of the triangular groove 452, the limiting spring 462 will push the limiting block 461 back, so that it is pushed into the triangular groove 452 corresponding to the contour, restricting the position of the sliding positioning block 451 so that it cannot be pushed back towards the rectangular groove 442. At this time, it can only be pushed towards the mounting rod 1 until it reaches the limit position and the limiting steel balls 43 on both sides lock the mounting rod 1.

[0041] Furthermore, such as Figure 10 As shown, a rotating connecting plate 463 is fixedly connected to the lower end of each of the multiple limiting blocks 461, and the rotating connecting plates 463 on the left and right sides are symmetrical to each other. A control shaft 464 is provided at the end of each side of the two rotating connecting plates 463 that are close to each other. Both ends of the control shaft 464 are rotatably connected to the interior of the passage groove 446. In the initial state, the control shafts 464 and the rotating connecting plates 463 on both sides are constrained by the limiting springs 462, and their positional relationship is relatively stable. Figure 10 As shown, a set of gear teeth is provided on the side of the two control shafts 464 that are close to each other, and the two sets of gear teeth mesh. When the rotating connecting plate 463 on one side is pushed, the two meshing control shafts 464 will rotate in the corresponding direction, causing the two sets of limit blocks 461 on the upper side to open to both sides for easy disassembly. Therefore, the lower end of the limit block 461 on the same side as the side slot 447 is provided with a release handle 465. The end of the release handle 465 near the limit block 461 is also fixedly connected to the rotating connecting plate 463. The end of the release handle 465 away from 461 passes through the side slot 447. The release handle 465 is manually turned to push the rotating connecting plate 463 on one side, causing the two meshing control shafts 464 to rotate in the corresponding direction, and the two sets of limit blocks 461 on the upper side to open to both sides, so that the positioning device 45 can be taken out and the corresponding limit mechanism 4 can be disassembled.

[0042] Therefore, the specific implementation method of this embodiment is as follows: During installation, the limiting mechanisms 4 located on the upper and lower sides are first placed in a staggered manner. When the sliding positioning block 451 located on the upper side is placed into the straight groove 441 from the rectangular groove 442 with the same outline on the lower side, the limiting piece 47 needs to be pulled out, which can cause the thrust spring 48 to lose its constraint and release its elastic force. The sliding positioning block 451 will push the limiting mechanism 4 located on the upper side towards the mounting rod 1. During this process, the sliding positioning block 451 will push open the limiting blocks 461 and the limiting spring 462 on both sides. When the limiting block 461 that has just been pushed corresponds to the position of the triangular groove 452, the limiting spring 462 will... The limit block 461 will be pushed back into the triangular groove 452 corresponding to the contour, restricting the position of the sliding positioning block 451 so that it cannot be pushed back. At this time, it can only be pushed towards the mounting rod 1 until it reaches the limit position, so that the limit steel balls 43 on both sides lock the mounting rod 1, thus completing the installation of the limit mechanism 4. If it is necessary to loosen and disassemble the limit mechanism 4, simply manually turn the release handle 465 to push the rotating connecting plate 463 on one side, so that the two meshing control shafts 464 will rotate in the corresponding direction, and the two sets of limit blocks 461 on the upper side will open to both sides. At this time, the upper positioning device 45 can be removed to complete the disassembly of the corresponding limit mechanism 4.

[0043] Example 2

[0044] This embodiment further improves the fixing mechanism 3 based on the first embodiment, so as to lock the position of the limiting mechanism 4 and improve the structural stability of the cable outlet rod.

[0045] Specifically, such as Figure 2 As shown, the fixing mechanism 3 includes a positioning bolt 31. The fixing threaded hole 421 on the same side is threadedly connected to the corresponding positioning bolt 31. The outer wall of the positioning bolt 31 is also provided with multiple positioning nuts 32. The positioning nuts 32 are located between the upper and lower fixing threaded holes 421 on the same side. During installation, the positioning nuts 32 need to be placed between the upper and lower fixing threaded holes 421. Apply screw glue downward from the uppermost fixing threaded hole 421 and start tightening the positioning bolt 31. The positioning bolt 31 passes through the fixing threaded hole 421 and the positioning nut 32 in sequence with staggered spacing. Tightening the positioning bolt 31 completes the installation. This prevents the limiting mechanism 4 of the cable outlet rod from loosening and falling off during long-term use, thus improving safety.

[0046] Furthermore, such as Figure 11As shown, the cable outlet mechanism 2 includes a mounting plate 21. Multiple mounting holes 22, corresponding to and symmetrically arranged with the positioning threaded holes 411, are provided on both sides of the mounting plate 21 for installation with the corresponding positioning threaded holes 411. Each mounting hole 22 is fixedly connected to the corresponding positioning threaded hole 411 by bolts. Two limiting blocks 24 are fixedly installed on the side of the mounting plate 21 away from the limiting mechanism 4. A rotating plate 25 is rotatably connected between the two limiting blocks 24. Adjustable bolts 23 are provided at the rotation axis of the limiting blocks 24 and the rotating plate 25. Loosening the adjustable bolts 23 allows for arbitrary adjustment of the angle between the rotating plate 25 and the mounting plate 21 to accommodate different positions of the equipment. Multiple cable protectors 26 are provided at the upper end of the rotating plate 25, which are used to connect and support the wires.

[0047] Therefore, the specific implementation method of this embodiment is as follows: During installation, first place the positioning nut 32 between the upper and lower fixing threaded holes 421, apply screw glue downward from the uppermost fixing threaded hole 421 and start tightening the positioning bolt 31. The positioning bolt 31 passes through the fixing threaded hole 421 and the positioning nut 32 in sequence and is tightened. Then, screw multiple bolts into the corresponding mounting holes 22 and fixing threaded holes 421 and apply screw glue to lock them. Finally, loosen the adjustable bolt 23 and adjust the rotating plate 25 to the appropriate position and tighten it.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
