Description

Technical Field

[0001] This utility model relates to the field of power construction equipment technology, and in particular to a busbar flange fitting tool. Background Technology

[0002] During the assembly of power GIS equipment, two busbar sections need to be connected through flanges at their ends. The common assembly method is as follows: the assembly personnel push the busbar to be installed and manually shake, lift, and swing it to insert the contacts of the busbar to be installed into the contact seats of the fixed busbar section. Finally, the flanges are aligned and bolts are tightened.

[0003] The above-mentioned busbar flange connection method requires manual operation such as shaking and swaying to align the flanges, which consumes a lot of manpower. Furthermore, the shaking and swaying may generate debris between the flanges and cause damage. Therefore, the assembly of busbar flanges is relatively troublesome and inefficient.

[0004] Therefore, this application proposes a busbar flange fitting tool to improve the ease of assembly when assembling busbar flanges. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a busbar flange fitting tool to solve the problem of inconvenient busbar flange connection mentioned in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a busbar flange fitting fixture, including a long strip rigid support body, a traction toothed rack at the top of the rigid support body, fixed clamping blocks symmetrically arranged at both ends of the bottom of the rigid support body, an assembly drive device that can translate along the axial direction of the rigid support body, and a limiting component on the assembly drive device.

[0007] The assembly drive device has a movable clamping block at its bottom, and the bottom of the fixed clamping block is flush with the bottom of the movable clamping block. The assembly drive device is used to drive the movable clamping block to move along the rigid support to change the distance between it and the fixed clamping block.

[0008] Preferably, the assembly drive device includes a horizontal slider, and a sliding guide rail is provided on the side of the horizontal slider, which passes through the horizontal slider. The rigid support body passes through the sliding guide rail and is connected to the horizontal slider.

[0009] The top of the horizontal slider is provided with a through groove, which is connected to the sliding guide rail. A rotatable drive gear is provided in the through groove, and the drive gear meshes with the traction gear row.

[0010] The horizontal slider is equipped with a driving component, which is used to drive the drive gear to rotate.

[0011] The limiting component is installed in the horizontal slider to limit the rotation direction of the drive gear.

[0012] Preferably, the cross-section of the sliding guide rail is adapted to the cross-section of the rigid support.

[0013] Preferably, the driving component includes a gear drive seat, the lower end of which is coaxially connected to the outer surface of the horizontal slider with the drive gear, and the gear drive seat is rotatable. A rotatable drive ratchet is provided between the two inner walls of the gear drive seat, and the end of the drive ratchet abuts against the two adjacent tooth grooves of the drive gear to drive the drive gear to rotate.

[0014] The outer surface of the gear drive housing is provided with an outwardly extending drive arm.

[0015] Preferably, the cross-section of the driving ratchet is comma-shaped, and the end of the driving ratchet can engage unidirectionally with the tooth groove of the driving gear.

[0016] Preferably, the limiting member is an L-shaped limiting tooth, which is rotatably installed in the through groove with the L-shaped corner as the axis, and one end of the bottom of the limiting tooth meshes with the drive gear.

[0017] There is a gap between the side of the limiting tooth away from the through groove and the inner wall of the through groove, and this gap is smaller than the height of the limiting tooth.

[0018] Preferably, the outer surface at the corner of the limiting tooth is provided with an elastic element limiting groove, the elastic element limiting groove is provided with an elastic element mounting shaft, the elastic element mounting shaft is provided with a torsion spring, one end of the torsion spring abuts against the inner wall of the elastic element limiting groove, and the other end of the torsion spring abuts against the inner wall of the through groove.

[0019] Preferably, the opposing surfaces of the fixed clamping block and the movable clamping block are provided with protective pads, and the protective pads are made of nylon.

[0020] As described above, the busbar flange fitting tool of this utility model has the following beneficial effects:

[0021] 1. This utility model features a traction toothed rack at the top of a rigid support body and symmetrically fixed clamping blocks at both ends of the bottom of the rigid support body. An assembly drive device is also installed on the rigid support body, with a movable clamping block adapted to the fixed clamping blocks at the bottom of the assembly drive device. The assembly drive device drives the movable clamping blocks to move horizontally, and in conjunction with the fixed clamping blocks, applies pushing and pulling forces to the busbar flanges. This causes the busbar flanges on both sides to merge together evenly and at a constant speed, achieving a smooth and linear pull-together motion of the flanges. This solves the various drawbacks of manual shaking and achieves a convenient user experience.

[0022] 2. This utility model sets a gear drive seat hinged to a horizontal slider and sets a driving ratchet in the gear drive seat. By rotating the gear drive seat, the driving ratchet drives the driving gear to rotate, thereby converting rotational power into linear power, thus achieving the effect of horizontally pulling in the flanges on both sides. At the same time, when the gear drive seat rotates to the left, the driving ratchet jumps along the outer surface of the driving gear under the action of the arc surface. When the gear drive seat rotates to the right, the end of the driving ratchet is embedded in the tooth groove of the driving gear to drive the driving gear. This achieves the purpose of driving the horizontal slider to move in the same direction by reciprocating the gear drive seat, thus achieving the effect of convenient driving.

[0023] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0031] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0032] Please see Figures 1 to 5It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0033] like Figure 1 and Figure 5 As shown, this utility model provides a busbar flange fitting fixture, including a long strip rigid support body 1, a traction toothed rack 11 on the top of the rigid support body 1, fixed clamping blocks 12 symmetrically arranged at both ends of the bottom of the rigid support body 1, an assembly drive device 2 that can translate along the axial direction of the rigid support body 1 on the rigid support body 1, and a limiting component on the assembly drive device 2.

[0034] The bottom of the assembly drive device 2 is provided with a movable clamping block 3. The bottom of the fixed clamping block 12 is flush with the bottom of the movable clamping block 3. The assembly drive device 2 is used to drive the movable clamping block 3 to move along the rigid support body 1 to change the distance between it and the fixed clamping block 12.

[0035] In use, the two busbar flanges are placed between the two sets of busbar flange fitting fixtures and abut against the inner walls of the fixed clamping block 12 and the movable clamping block 3 respectively. The two sets of busbar flange fitting fixtures are symmetrically arranged. At the same time, the assembly drive device 2 is driven to move the movable clamping block 3 toward the fixed clamping block 12 to apply a pushing force to the busbar flanges, thereby bringing the busbar flanges on both sides closer to the middle to complete the fitting.

[0036] This device replaces manual shaking with a smooth mechanical push, completely eliminating the impact and friction on the silver-plated conductive surface during the docking process, thus fundamentally preventing damage to the silver plating layer. Simultaneously, the smooth insertion process generates no metal debris, ensuring the cleanliness of the GIS chamber and significantly reducing the risk of insulation discharge caused by impurities. Furthermore, this device can be operated by one to two people, greatly reducing labor intensity and skill requirements, and significantly improving assembly efficiency.

[0037] like Figure 1 and Figure 2As shown, in some embodiments, the assembly drive device 2 of this utility model includes a horizontal slider 21. The side of the horizontal slider 21 is provided with a sliding guide rail 22 that passes through the horizontal slider 21. The rigid support body 1 passes through the sliding guide rail 22 and is connected to the horizontal slider 21, so that the horizontal slider 21 can move horizontally along the axial direction of the rigid support body 1, thereby stably driving the movable clamping block 3 to move to change the distance between it and the fixed clamping block 12 to apply pressure to the busbar flange.

[0038] The top of the horizontal slider 21 is provided with a through groove 23, which is connected to the sliding guide rail 22. A rotatable drive gear 24 is provided in the through groove 23. The drive gear 24 meshes with the traction gear row 11. When the drive gear 24 is driven by power and rotates, the drive gear 24 can drive the horizontal slider 21 to move horizontally along the track of the traction gear row 11 due to its meshing relationship with the traction gear row 11.

[0039] The horizontal slider 21 is equipped with a driving component, which is used to drive the drive gear 24 to rotate;

[0040] The limiting component is installed in the horizontal slider 21 to limit the rotation direction of the drive gear 24, so as to prevent the horizontal slider 21 from retracting under the pressure of the bus flange due to the reverse rotation of the drive gear 24, and to improve the convenience of driving the drive gear 24 to rotate.

[0041] like Figure 1 As shown, in some embodiments, the cross section of the sliding guide rail 22 of this utility model is adapted to the cross section of the rigid support body 1, so that the interior of the sliding guide rail 22 is completely in contact with the outer surface of the rigid support body 1, avoiding swaying during the movement of the horizontal slider 21, thereby improving the stability of the drive bus flange closing.

[0042] like Figure 1 and Figure 2 As shown, in some embodiments, the driving component of this utility model includes a gear drive seat 25. The gear drive seat 25 has an inverted U-shaped connecting groove inside and straddles the through groove 23. The lower end of the gear drive seat 25 is coaxially connected to the outer surface of the horizontal slider 21 with the drive gear 24, and the gear drive seat 25 is rotatable. A rotatable drive ratchet 26 is provided between the two inner walls of the gear drive seat 25. The end of the drive ratchet 26 abuts against the two adjacent tooth grooves of the drive gear 24 to drive the drive gear 24 to rotate. An outwardly extending drive arm 27 is provided on the outer surface of the gear drive seat 25.

[0043] In use, the driving arm 27 drives the gear drive seat 25 to rotate via the lever principle. When the gear drive seat 25 rotates toward the fixed clamping block 12, the driving ratchet 26 slides along the outer surface of the driving gear 24. When the gear drive seat 25 rotates away from the fixed clamping block 12, the end of the driving ratchet 26 inserts into the tooth groove of the driving gear 24 and drives the driving gear 24 to rotate under the pressure of the driving arm 27. The rotating driving gear 24, in the relationship of meshing with the traction gear row 11, drives the horizontal slider 21 to move along the track of the traction gear row 11 toward the fixed clamping block 12. Thus, pressure is applied to the busbar flanges on both sides through the fixed clamping block 12 and the movable clamping block 3 to complete the closing of the busbar flanges.

[0044] like Figure 3 As shown, in some embodiments, the cross-section of the driving ratchet 26 of this invention is comma-shaped, and the end of the driving ratchet 26 can engage unidirectionally with the tooth groove of the driving gear 24. When the gear drive seat 25 drives the driving ratchet 26 to rotate, the driving ratchet 26 rotates towards the driving gear 24, and then the driving ratchet 26 slides along the surface of the driving gear 24. When the driving ratchet 26 rotates in the opposite direction, the bent end of the driving ratchet 26 will be inserted into the tooth groove of the driving gear 24 and be limited, so that the driving ratchet 26 cannot rotate. At this time, if pressure is continued to be applied to the driving ratchet 26, the driving gear 24 can be driven to rotate through the driving ratchet 26, thereby achieving the effect of driving with less effort and more convenience. Its specific working principle can be referred to the ratchet assembly.

[0045] like Figure 4 As shown, in some embodiments, the limiting member of this utility model is an L-shaped limiting tooth 28. The limiting tooth 28 is rotatably installed in the through groove 23 with the L-shaped corner as the axis, and one end of the bottom of the limiting tooth 28 meshes with the drive gear 24.

[0046] There is a gap between the side of the limiting tooth 28 away from the through groove 23 and the inner wall of the through groove 23, and this gap is smaller than the height of the limiting tooth 28.

[0047] When the drive gear 24 rotates counterclockwise, its teeth press down on the bottom of the limiting tooth 28, causing the limiting tooth 28 to swing. When the drive gear 24 rotates clockwise, it drives the limiting tooth 28 to rotate from its bottom. At this time, the left side of the limiting tooth 28 abuts against the inside of the through groove 23 and gets stuck, thus limiting the rotation direction of the drive gear 24 to prevent the horizontal slider 21 from retracting under pressure. If necessary, the limiting tooth 28 can be manually rotated by rotating its top to release its bottom from the drive gear 24, allowing the horizontal slider 21 to be moved manually. This facilitates large-scale movement of the horizontal slider 21 and quick disassembly of the device after the busbar flange is closed.

[0048] like Figure 4 As shown, in some embodiments, the outer surface of the corner of the limiting tooth 28 of this utility model is provided with an elastic element limiting groove 281, and an elastic element mounting shaft 282 is provided in the elastic element limiting groove 281. A torsion spring is provided on the elastic element mounting shaft 282. One end of the torsion spring abuts against the inner wall of the elastic element limiting groove 281, and the other end of the torsion spring abuts against the inner wall of the through groove 23. Thus, the torsion spring always applies pressure to the limiting tooth 28, so that the limiting tooth 28 can immediately return to its initial state after being driven to rotate by the drive gear 24, so as to avoid the limiting tooth 28 from failing to return to its position and losing the effect of limiting the drive gear 24.

[0049] like Figure 1 As shown, in some embodiments, the opposing surfaces of the fixed clamping block 12 and the movable clamping block 3 of this utility model are provided with protective pads 4, which are made of nylon. When the busbar flange is pressurized by the fixed clamping block 12 and the movable clamping block 3, the movable clamping block 3 is used to protect the busbar flange to avoid damage to the busbar flange caused by the hard fixed clamping block 12 and the movable clamping block 3.

[0050] In summary, the busbar flange closing fixture of this utility model has a traction toothed rack 11 on the top of the rigid support body 1, and fixed clamping blocks 12 are symmetrically arranged at both ends of the bottom of the rigid support body 1. At the same time, an assembly drive device 2 is set on the rigid support body 1, and a movable clamping block 3 adapted to the fixed clamping block 12 is set at the bottom of the assembly drive device 2. The assembly drive device 2 drives the movable clamping block 3 to move horizontally, and in conjunction with the fixed clamping block 12, applies pushing and pulling forces to the busbar flange, so that the busbar flanges on both sides are evenly and uniformly closed together, realizing the smooth and straight closing of the flange, solving the various drawbacks caused by manual shaking, and achieving the effect of convenient use.

[0051] This invention features a gear drive seat 25 hinged to a horizontal slider 21, with a driving ratchet 26 within the gear drive seat 25. Rotating the gear drive seat 25 causes the driving ratchet 26 to drive the driving gear 24, converting rotational power into linear power, thus achieving the effect of horizontally pulling in the flanges on both sides. Simultaneously, when the gear drive seat 25 rotates to the left, the driving ratchet 26 bounces along the outer surface of the driving gear 24 under the action of the arc-shaped surface. When the gear drive seat 25 rotates to the right, the end of the driving ratchet 26 engages in the tooth groove of the driving gear 24, driving the driving gear 24. This allows the reciprocating motion of the gear drive seat 25 to drive the horizontal slider 21 to move in the same direction, achieving convenient driving.

[0052] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0053] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
