Description

Technical Field

[0001] This invention relates to the field of angle tower technology, specifically to a double-circuit compact transmission line suspension angle tower. Background Technology

[0002] A double-circuit angle tower is a structure in which two independent three-phase transmission lines are compactly arranged on the crossarms, conductor suspension points, and other structures of a single tower. Compared with a single-circuit tower, a double-circuit tower can significantly save the land occupied by the line corridor, reduce the spacing between the two lines and between the phase conductors of the same line, and reduce the overall size of the tower while ensuring electrical safety distance.

[0003] In related technologies, angle towers use suspension clamps to hold cables. For example, a scheme using vertically arranged double-clamp suspension clamps (announcement number CN207801418U) connects the upper and lower suspension clamps to the upper and lower ends of the suspension clamp body, respectively, and fixes them to the connecting sleeve with fixing bolts. This allows for stepless adjustment of the phase spacing between the two clamps, resulting in high installation efficiency and reduced labor intensity.

[0004] The suspension clamp described above is a commonly used type, usually connected to an insulating string. However, when such a suspension clamp is used to suspend a cable, it is difficult to bend the cable because the suspension clamp is restricted by the position of the insulating string, resulting in poor flexibility.

[0005] Some corner towers use star-shaped plates to wrap around several cables to control the cable spacing. The cable ends must pass through the star-shaped plate to complete the installation, which makes it inconvenient to tighten the cables at any point. Summary of the Invention

[0006] The purpose of this invention is to provide a double-circuit compact transmission line suspension angle tower to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A double-circuit compact transmission line suspension angle tower includes a tower body, an insertable cable bundler, an insertable cable bundler, and an angle bracket, adapting to the cable limiting requirements of different laying scenarios. The tower body is equipped with crossarms for suspending cables. Multiple crossarms can suspend more cables, reducing the number of corner towers required and saving land. The insertable cable bundler includes a first limiting plate with a plurality of first cable outlets on its surface. A plurality of anti-detachment components are installed on the first limiting plate to block the first cable outlets. The cable is located between the first cable outlets and the anti-detachment components. The cable can be directly inserted into the insertable cable bundler, which is convenient to operate and can flexibly tighten the cable. The insertable cable bundler includes a second limiting plate with several second cable release ports on its surface. A claw plate is plugged into the second limiting plate, and the claw plate corresponds to the position of the second cable release port. The cable is located between the second cable release port and the claw plate. The insertable cable bundler can be installed at any position of the cable, reducing the difficulty of high-altitude operations. The corner unit is connected to the crossarm via an insulating string. The corner unit includes a ring rail with two suspension brackets slidingly mounted on it. Each suspension bracket has a combination plate, and the two suspension brackets are spliced ​​together via the combination plate. The combination plate is connected to a clamp for holding the cable, which can flexibly adapt to the angle turning requirements of the suspension corner tower. The clamp is rotatably connected to a cable support for supporting the cable, thus protecting the cable from excessive sag and wear due to its own weight or wind force.

[0008] Furthermore, the anti-detachment component includes a limiting claw and an arc-shaped baffle. The arc-shaped baffle unidirectionally locks the limiting claw. The limiting claw is rotatably connected to the first limiting plate through a first fastener. The arc-shaped baffle is fixedly connected to the side of the first limiting plate, realizing unidirectional anti-detachment locking after the cable is put into the first cable release port, preventing the cable from coming out of the first cable release port under the action of external forces such as wind force and its own weight, making cable installation more convenient.

[0009] Furthermore, the two limiting claws are arranged as a group and set on both sides of the first limiting plate. The two limiting claws will not block each other. The limiting claws have limiting parts, which contact the arc-shaped baffle. The rotation angle of the limiting claws can be precisely controlled to ensure the stability of the anti-loosening locking and improve the limiting effect of the insertion cable tie on the cable.

[0010] Furthermore, the second limiting plate has a prismatic hole in the center of its surface, and the claw plate has a prism in the center of its surface that inserts into the prismatic hole. This effectively prevents the claw plate from rotating or shifting during operation. The prism also has a backstop. The claw plate has an integrally formed claw, which has higher structural strength and is not easily deformed or damaged. The claw is fitted over the outside of the cable and works with the second limiting plate to tighten the cable.

[0011] Furthermore, the anti-reverse component includes a stud and a nut. The stud is integrally formed with the prism and has an anti-reverse hole. A cotter pin is inserted into the anti-reverse hole, which can effectively prevent the nut from loosening due to vibration, wind, or other factors, thereby avoiding the failure of the connection between the claw plate and the second limiting plate and significantly improving the reliability of the plug-in cable tie connection structure.

[0012] Furthermore, four support rods are connected to the upper surface of the ring rail, and suspension plates are fixedly connected to the upper ends of the four support rods. The suspension plates are connected to the insulating strings, which can make the ring rail more evenly stressed and avoid the ring rail tilting or deformation caused by single or two-point suspension, thus ensuring the structural stability of the corner device when bearing the weight of the cable and resisting wind loads.

[0013] Furthermore, the cross-section of the ring rail is H-shaped, and the suspension bracket has a locking jaw to fit the ring rail, enhancing the fit between the suspension bracket and the ring rail. The suspension bracket is screwed with an anti-slip bolt to abut against the ring rail, enabling the suspension bracket to be fixed at any position on the ring rail and adapting to the adjustment requirements of different steering angles. A second fastener is installed on the combination plate to prevent the suspension bracket from falling off the ring rail.

[0014] Furthermore, the cable clamp includes a cable tray plate and a pressure plate, with the cable located between the cable tray plate and the pressure plate. The pressure plate is fitted onto the surface of the second fastener. The cooperation between the cable tray plate and the pressure plate can form a stable wrapping and clamping of the cable, making it more convenient to clamp the cable.

[0015] Furthermore, the cable support includes a bending plate and a cable support plate fixedly connected to the bending plate. The cable support plate and the cable channel plate have hexagonal grooves on their surfaces. The cable support plate and the cable channel plate are connected by the hexagonal grooves and a third fastener. Multiple cable support plates can be combined to provide good support for the cable and also assist in cable bending.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) The suspension frame can be hoisted by using the ring rail, and the suspension frame can slide along the ring rail to adjust the position of the wire clamp. The position of the wire clamp can be adjusted according to the turning angle of the cable to make the wire clamp and the cable direction perfectly match, avoiding the cable from hard bending or stress concentration due to the fixed position of the wire clamp. The wire clamp is flexible in arrangement and the cable bending is more convenient.

[0017] (2) The limiting claw can prevent the cable from falling out of the first cable release port. By rotating and adjusting the position of the limiting claw, the cable can be quickly assembled with the cable tray without the cable end passing through the first cable release port. The cable tray can be freely installed at any position of the cable, simplifying the operation steps of high-altitude operations and making it more convenient to control the cable spacing.

[0018] (3) The second limiting plate and the claw plate can be connected to the cable separately. Then, the second limiting plate and the claw plate are assembled, which reduces the installation difficulty during high-altitude operations. The claws of the claw plate can form an all-round wrapping lock on the cable, effectively preventing the cable from moving or falling off under the action of external forces such as wind and self-weight, ensuring the stability of cable laying. The plug-in cable tie can be flexibly installed and disassembled at any position of the cable without being limited to the cable end or specific node.

[0019] (4) The cable is supported by the cable support plate. The cable support plate can rotate to adapt to the turning angle of the cable. Multiple cable support plates can be combined in sequence by bending plates. The support range can be flexibly expanded according to the turning arc of the cable. Two clamps can also be connected together to make the support effect of the cable more stable. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example: Please see Figure 1-9The present invention provides a technical solution: A double-circuit compact transmission line suspension angle tower includes a tower body 100, an insert-type cable bundler 500, an insert-type cable bundler 600, and an angler 700. The tower body 100 crossarm 200 provides suspension support for the double-circuit cables 400. With the two cable bundler components of different structures, the insert-type cable bundler 500 and the insert-type cable bundler 600, the tower body 100 can flexibly meet the cable bundler requirements of different specifications of cables 400, and the spacing of multiple cables 400 can be controlled more flexibly and conveniently. The tower body 100 and crossarm 200 are mainly composed of angle steel, steel plates, sleeves, bolts, foot nails, washers and other components of different specifications. All components are hot-dip galvanized for corrosion protection and assembled into an angle tower. The connection of the components of the angle tower is mainly by bolt connection, with a few welded connections. When welding steel of different strengths, welding materials that are compatible with low-strength steel are used.

[0024] The tower body 100 is equipped with several crossarms 200 for suspending cables 400. Each crossarm 200 is arranged in layers along the height of the tower body 100 to meet the spatial layout requirements of a double-circuit compact transmission line. Each layer of crossarm 200 corresponds to the support of the three-phase cable of one transmission line. The end of the crossarm 200 is equipped with a hanging point structure that is compatible with the insulation string 300. The number and spacing of the hanging points can be flexibly adjusted according to the cross-sectional specifications and load parameters of the cable 400 to ensure stable suspension support for the double-circuit cable, effectively disperse the force of the cable 400's self-weight and wind load on the tower body 100, and improve the mechanical stability of the overall structure.

[0025] The insertable cable bundler 500 includes a first limiting plate 501. The surface of the first limiting plate 501 has several first cable outlets 505. The first cable outlets 505 are U-shaped. Several anti-detachment components are installed on the first limiting plate 501 to block the first cable outlets 505. The cable 400 is located between the first cable outlets 505 and the anti-detachment components. The anti-detachment components can maintain the state of the cable 400 in the first cable outlets 505 and can tighten multiple cables 400 together. This can control the spacing of the cables 400 and prevent the cables 400 from contacting each other.

[0026] The insertable cable bundler 600 includes a second limiting plate 601. The first limiting plate 501 has the same structure as the second limiting plate 601. The surface of the second limiting plate 601 has several second cable release ports 605. A claw plate 602 is plugged into the second limiting plate 601. The claw plate 602 corresponds to the position of the second cable release ports 605. The cable 400 is located between the second cable release ports 605 and the claw plate 602. The claw plate 602 and the second limiting plate 601 can be separated and connected to the cable 400 separately, which facilitates the installation of the insertable cable bundler 600 at any position of the cable 400. At the same time, the cable 400 can also pass directly through the insertable cable bundler 600, providing different cable 400 tightening methods.

[0027] The corner bracket 700 is connected to the crossarm 200 via an insulating string 300. The corner bracket 700 includes a ring rail 703, on which two suspension brackets 704 slide. Each suspension bracket 704 has a combination plate 712, and the two suspension brackets 704 are spliced ​​together via the combination plate 712, so that the two suspension brackets 704 can be locked inside and outside the ring rail 703, ensuring that the ring rail 703 and the suspension brackets 704 are stably assembled. The combination plate 712 is connected to a clamp that holds the cable 400. The clamp can hold the cable 400 tightly to prevent the cable 400 from slipping. The clamp is rotatably connected to a cable support that supports the cable 400, which can prevent the cable 400 from sagging.

[0028] In this embodiment, as Figure 3 As shown, the anti-detachment component includes a limiting claw 502 and an arc-shaped baffle 503. The arc-shaped baffle 503 unidirectionally clamps the limiting claw 502. When the cable 400 is between the limiting claw 502 and the first cable release port 505, the arc-shaped baffle 503 can prevent the limiting claw 502 from rotating. At this time, the limiting claw 502 cannot rotate counterclockwise. The limiting claw 502 is rotatably connected to the first limiting plate 501 through the first fastener 504, which facilitates the assembly of the limiting claw 502. The arc-shaped baffle 503 is fixedly connected to the side of the first limiting plate 501. One arc-shaped baffle 503 can restrict the rotation of two limiting claws 502. Two limiting claws 502 are set as a group and are arranged on both sides of the first limiting plate 501 to achieve a staggered distribution of a pair of limiting claws 502. The rotation of the two limiting claws 502 does not affect each other. The limiting claws 502 are equipped with limiting parts 506, which contact the arc-shaped baffle 503, increasing the contact area between the limiting claws 502 and the arc-shaped baffle 503, and improving the anti-rotation effect. Figure 3 In the middle, the arc-shaped baffle 503 does not restrict the clockwise rotation of the limiting claw 502, making it easy to adjust the position of the limiting claw 502; when the cable 400 passes through the first cable release port 505, one of the pair of limiting claws 502 can be rotated first to insert the cable 400 obliquely into the first cable release port 505, while bending the cable 400 to avoid the limiting claw 502. Then the limiting claw 502 is reset, at which point the limiting claw 502 is outside the cable 400. Then the other limiting claw 502 is also placed outside the cable 400 in the same way. The cable 400 is locked in the first cable release port 505 by the pair of limiting claws 502.

[0029] In this embodiment, as Figure 5 and Figure 6As shown, the second limiting plate 601 has a prismatic hole 607 in the middle of its surface, and the claw plate 602 has a prism 606 in the middle of its surface that is inserted into the prismatic hole 607. The prismatic hole 607 and the prism 606 restrict the rotation of the claw plate 602, which can ensure that the claw plate 602 locks the cable 400. The prism 606 has a backstop, which can prevent the claw plate 602 and the second limiting plate 601 from separating accidentally. The claw plate 602 has an integrally formed claw 609, which is not easy to break or deform. The claw 609 is sleeved on the outside of the cable 400 and, together with the second cable release port 605, can tighten the cable 400. The anti-reverse component includes a stud 603 and a nut 608. The stud 603 and the prism 606 are integrally formed. The stud 603 is provided with an anti-reverse hole, in which a cotter pin 604 is inserted. When assembling the cable tie 600 with the cable 400, first remove the cotter pin 604, then unscrew the nut 608, separate the second limiting plate 601 and the claw plate 602, put the cable 400 into the second cable release port 605, and the claw 609 covers the cable 400. Then, the prism 606 is inserted into the prism hole 607, and the second limiting plate 601 and the claw plate 602 are fixed by the nut 608. The cotter pin 604 is installed on the stud 603. The cotter pin 604 prevents the nut 608 from falling off. Other fasteners are also equipped with cotter pins 604 to ensure the stability of the screw connection.

[0030] In this embodiment, as Figure 7 As shown, four support rods 701 are connected to the upper surface of the ring rail 703. Suspension plates 702 are fixedly connected to the upper ends of the four support rods 701. The suspension plates 702 are connected to the insulating string 300, and are installed and fixed with screws and nuts. Finally, the ring rail 703 is connected to the crossarm 200. The insulating string 300 is non-conductive, and the power on the cable 400 will not be conducted to the crossarm 200 and the tower body 100, ensuring power transmission safety. The suspension plate 702 is triangular to ensure the stability of the ring rail 703 suspension. In this embodiment, as Figure 7 and Figure 8 As shown, the cross-section of the ring rail 703 is H-shaped, and the suspension bracket 704 has a clamping mouth 713 that fits onto the ring rail 703. The size of the clamping mouth 713 is slightly larger than that of the ring rail 703, allowing it to slide along the ring rail 703. The suspension bracket 704 is screwed with an anti-slip bolt 705 that abuts against the ring rail 703. Tightening the anti-slip bolt 705 can restrict the sliding of the suspension bracket 704, thereby achieving the positioning of the cable clamp. The combination plate 712 is equipped with a second fastener 714. The two second fasteners 714 are used to connect a pair of suspension brackets 704, ensuring that the suspension bracket 704 is stably connected to the ring rail 703.

[0031] In this embodiment, as Figure 8 and Figure 9As shown, the cable clamp includes a cable tray plate 707 and a pressure plate 706. The cable tray plate 707 is approximately U-shaped, and the pressure plate 706 is arc-shaped. The cable is located between the cable tray plate 707 and the pressure plate 706. The pressure plate 706 is provided with hanging holes. The pressure plate 706 is fitted onto the surface of the second fastener 714 using the hanging holes. Both the cable tray plate 707 and the pressure plate 706 are provided with three holes. The cable tray plate 707 and the pressure plate 706 can be assembled using screws and nuts. Tightening the nuts can control the clamping of the cable 400 by the cable tray plate 707 and the pressure plate 706. The screws have a certain length and can clamp cables 400 of different thicknesses.

[0032] In this embodiment, as Figure 8 and Figure 9 As shown, the cable support includes a bending plate 709 and a cable support plate 708 fixedly connected to the bending plate 709. One end of the bending plate 709 is bent downwards to ensure that the two cable support plates 708 are at the same height after combination. The cable support plate 708 and the cable tray plate 707 have hexagonal grooves 710 on their surfaces. The cable support plate 708 and the cable tray plate 707 are connected to a third fastener 711 through the hexagonal grooves 710. The hexagonal head of the screw of the third fastener 711 is placed in the hexagonal groove 710, which can prevent the cable 400 from contacting the hexagonal head of the screw and thus prevent wear on the cable 400. The cable support plate 708 can rotate to adapt to the bend of the cable 400. By using multiple bending plates 709, adjacent cable tray plates 707 can also be connected together, thereby improving the stability of the cable support plate 708 in supporting the cable 400.

[0033] Specifically, during use, a concrete tower base is poured on the ground and anchoring components are pre-embedded to stably support the tower body 100, and an insulating string 300 is hoisted to the end of the crossarm 200 of the tower body 100. In the cable 400 sorting operation, a cable bundler 500 is used to gather and bundle multiple cables 400. The specific operation steps are as follows: rotate the limiting claw 502 to avoid the first cable release port 505, put the cable 400 into the first cable release port 505, and then reset the limiting claw 502. After the above operation, the pair of limiting claws 502, together with the first cable release port 505, can put the cable bundler 500 on the cable 400. Through the above operation, the cable bundler 500 can be flexibly placed at any position on the cable 400, and the fitting structure of the limiting claw 502 and the arc baffle 503 can effectively prevent the cable 400 from slipping and separating from the cable bundler 500. At the same time, multiple cables 400 are placed in different first cable release ports 505 of the cable bundler 500, which can accurately control the spacing between adjacent cables 400, avoid the cables 400 from tangling and rubbing against each other, and improve the regularity and safety of the cable arrangement. Multiple cables 400 are gathered and bundled using a pass-through cable bundler 600. The specific operating steps are as follows: First, remove the cotter pin 604 on the stud 603, loosen and remove the nut 608 at the end of the stud 603, so that the claw plate 602 of the pass-through cable bundler 600 separates axially from the second limiting plate 601, completely opening the second cable release port 605 channel on the second limiting plate 601. At this time, the cable 400 is placed into the second cable release port 605 of the second limiting plate 601. The claw plate 602 uses the claws 609 to hold the cable 400. The prisms 606 on the surface of the claw plate 602 are aligned with the prism holes 607 on the second limiting plate 601 and inserted to achieve circumferential positioning of the claw plate 602 and the second limiting plate 601, preventing relative rotation between the two. Then, the nut 608 and the cotter pin 604 are installed in sequence. The axial preload of the nut 608 makes the claw plate 602 and the second limiting plate 601 fit tightly, completing the assembly and locking of the entire through-type cable tie. The end of the cable 400 can pass through the insertion type cable tie 500 and the insertion type cable tie 600. The insertion type cable tie 500 relies on the locking structure of the limiting claw 502 and the arc-shaped baffle 503 to constrain the cable 400. There is no need to disassemble the insertion type cable tie 500, which is easy to operate and is suitable for cables 400 with a smaller diameter and good toughness. The insertion type cable tie 600 is suitable for cables 400 with a larger diameter and higher rigidity. The insertion type cable tie 600 adopts a split assembly structure of claw plate 602 and limiting plate. Through the circumferential positioning of prism 606 and prism hole 607 and the axial locking of nut 608 and cotter pin 604, it can provide stronger clamping and fixing force and is suitable for cables 400 with a larger diameter and higher rigidity. The suspension plate 702 is connected to the crossarm 200 by the insulating string 300. When the cable 400 turns, the anti-slip bolt 705 is loosened to release the locking constraint between the suspension bracket 704 and the ring rail 703. At this time, the suspension bracket 704 can drive the pressure plate 706, the cable tray plate 707, the cable support plate 708 and other components to slide freely along the arc trajectory of the ring rail 703, thereby adapting to the cable 400 laying path with different turning radii. The cable 400 at the bend is placed into the cable tray 707, and the pressure plate 706 is fastened to the cable tray 707 using screws and nuts. The clamping force between the pressure plate 706 and the cable tray 707 securely fixes the cable 400, preventing slippage during operation. A cable support plate 708 is installed below the bend of the cable 400. The tilt angle of the cable support plate 708 can be flexibly adjusted by a rotatable bending plate 709, so that the cable support plate 708 and the curvature of the cable 400 are completely fitted, forming uniform support for the cable 400 at the bend and avoiding stress concentration in the cable 400 due to local suspension. By using multiple sets of pressure plates 706, cable trays 707, and cable support plates 708, the cable 400 at the bend can be fixed. The position of the suspension plate 702 can be flexibly adjusted according to the turning angle of the cable 400 to adapt to the bending and laying requirements of cables 400 of different specifications. At the same time, the stability of the cable 400 in the turning section is improved through multiple fixing structures.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
