Description

Technical Field

[0001] This invention relates to the technical field of cable stranding, and more specifically to an overhead insulated conductor production equipment. Background Technology

[0002] As a core component of overhead power distribution lines, the stranding quality of overhead insulated conductors directly affects the safety and stability of transmission lines. Currently, cage stranding machines, as key equipment for producing overhead insulated conductors, are widely used in the stranding of multi-strand cables.

[0003] Existing cage stranding machines typically use a rotating cage to drive multiple wire feeding reels to rotate synchronously, stranding multiple single wires into strands.

[0004] However, in actual production, during the installation phase, operators need to manually thread the cables. They must simultaneously thread multiple strands of cable into the central area of ​​the rotating assembly and pull them to the take-up end, and manually pre-twist the ends of the cables. The pre-twisted cable ends are then fixed to the take-up end. The quality of the pre-twist is difficult to guarantee, and this increases the workload for workers, affecting work efficiency. Summary of the Invention

[0005] The main objective of this invention is to provide an overhead insulated conductor production equipment, which aims to solve the problem in related technologies where, during the installation stage before cable stranding, multiple strands of cable need to be pre-stranded manually and installed to the winding end when the cable is manually pulled for installation. Relying on manual labor makes it difficult to guarantee the initial stranding quality and affects work efficiency.

[0006] To achieve the above objectives, the technical solution provided by this invention is as follows: An overhead insulated conductor production equipment includes a rotating assembly, on which a cable winding reel is mounted, and a limit assembly and a traction assembly are sequentially arranged on one side of the output end of the rotating assembly. The limiting assembly includes a guide ring with a guide hole for the cable to pass through. The traction assembly includes a drive component and several connectors for fixing the cable ends. The connectors slide radially along the rotating assembly. The distance between the cable shaft fixed on the connector and the axis of the rotating assembly is less than the distance between the cable shaft located in the guide hole and the axis of the rotating assembly. The cable passes through the guide ring and the end is installed into the connector. The traction assembly is equipped with a fastening assembly, which is used to fasten the cable inside the connector and limit the radial slippage of the connector; The drive component is used to drive the connector to rotate so as to twist the multi-strand cable between the guide ring and the mounting assembly together; during the twisting process, after the multi-strand cable has completed the predetermined twisting length, the drive fastening assembly releases the restriction on the mounting assembly so as to drive the connector to slide radially to the axis under the action of the cable twisting force.

[0007] Specifically, the connector includes a connecting disc and a connecting plate. The connecting disc is coaxially arranged with the rotating component, and the connecting plate is slidably arranged on the connecting disc. A traction hole for passing a cable is opened at one end of the connecting plate near the axis of the connecting disc.

[0008] Specifically, the fastening assembly includes a trigger, a locking element, and a driving element that moves the trigger. The locking element is slidably mounted on the connecting plate, and a driving shaft is coaxially mounted on the connecting plate. The trigger is slidably mounted on the driving shaft and abuts against the locking element when it approaches the connecting plate, thereby driving the locking element to fasten the cable in the traction hole.

[0009] Specifically, the locking component includes a limiting plate and a pressing rod. Both the limiting plate and the pressing rod are slidably mounted on the connecting plate. The moving direction of the limiting plate is the same as the moving direction of the trigger. The pressing rod slides radially along the connecting plate. When the trigger presses against the limiting plate to drive it to slide, the limiting plate abuts against the pressing rod to drive it to move toward the traction hole, increasing the force on the cable in the traction hole.

[0010] Specifically, the fastening assembly also includes a limiting member, which includes a rack one disposed on the trigger member and a rack two disposed on the connecting plate, so that when the trigger member approaches the connecting plate, rack one and rack two engage to limit the position of the connecting plate in the radial direction of the connecting plate.

[0011] Specifically, the triggering component includes a connecting ring, an extension rod, a positioning plate, and a trigger plate. The connecting ring slides coaxially on the drive shaft, and the extension rod and connecting ring are sequentially arranged on the side of the positioning plate near the connecting plate. The trigger plate is slidably arranged on the positioning plate along the drive shaft axis, and an elastic element is arranged between the positioning plate and the trigger plate to drive the trigger plate to move toward the connecting plate. A rack is arranged on the positioning plate. When the positioning plate moves toward the connecting plate, the trigger plate first abuts against the limiting plate and drives the pressing rod to clamp the cable. Then, rack one meshes with rack two.

[0012] Specifically, an elastic element two is provided between the connecting plate and the connecting disk, and the elastic element two is configured to drive the connecting plate to move toward a position away from the axis of the connecting disk.

[0013] Specifically, the mounting component is slidably arranged along the axis of the rotating component, and the traction component also includes a second driving component, which is used to drive the mounting component to slide.

[0014] Specifically, a winding assembly is provided between the traction assembly and the limiting assembly. The winding assembly is connected to a drive component four that drives the winding assembly to slide horizontally perpendicular to the axis of the rotating assembly, so as to facilitate the disassembly of the winding assembly and make way for the traction assembly.

[0015] Specifically, the winding assembly is also connected to a drive component 5 that drives it to move up and down. The winding assembly includes a connecting shaft and a winding reel, and the winding reel is provided with fastening clips for fixing the cable.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting up a traction component to replace manual traction, the operator's operating procedures are reduced, and the installation efficiency of the cable is improved.

[0017] 2. By driving the clamping plate on which the cable is installed to rotate, the multiple cables between the limit ring and the connecting plate are pre-twisted, reducing the quality deviation caused by manual twisting and improving the twisting quality of the guide.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figures 1 to 10 An overhead insulated conductor production device includes a rotating assembly 1, a limiting assembly 2, and a traction assembly 3. A cable winding reel is mounted on the rotating assembly 1. The limiting assembly 2 and the traction assembly 3 are sequentially arranged on one side of the cable outlet end of the rotating assembly 1.

[0031] The limiting component 2 guides and limits the cable extending from the rotating component 1. The traction component 3 includes a connector 31 and a drive component 32 that drives the connector 31 to rotate. The connector 31 is slidably disposed along the radial direction of the rotating component 1.

[0032] A fastening assembly 4 is provided on the traction assembly 3. The fastening assembly 4 cooperates with the connector 31 to fasten the cable installed on the connector 31. At the same time, the fastening assembly 4 is used to limit the radial sliding of the connector 31. After the drive member 32 drives the connector 31 to rotate until multiple cables have completed a predetermined stranding length, the restriction of the fastening assembly 4 on the connector 31 is released. Then, under the action of the cable stranding force, the drive member 31 moves towards the axis of the rotating assembly 1.

[0033] Reference Figures 1 to 6 The traction assembly 3 includes a guide plate 33, a sliding block 34, and a connecting block 35. The guide plate 33 is located on one side of the outlet end of the rotating assembly 1 and extends axially toward the rotating assembly 1. The guide plate 33 is fixedly mounted on the ground. The sliding block 34 is mounted on the guide plate 33 and is located on the side of the limiting assembly 2 away from the rotating assembly 1. The connecting block 35 is fixedly mounted on the upper end of the sliding block 34.

[0034] Reference Figures 3 to 5 The connecting component 31 includes a connecting disc 311, a connecting plate 312, and a drive shaft 313. A through hole coaxial with the rotating component 1 is formed on the connecting block 35. The drive shaft 313 is coaxially rotatably disposed within the through hole on the connecting block 35. The connecting disc 311 is coaxially disposed on the end of the drive shaft 313 facing the rotating component 1. Multiple connecting rods 314 are evenly spaced along the circumference of the connecting disc 311 to achieve a fixed connection between the connecting disc 311 and the drive shaft 313. A guide groove 315 is formed on the connecting disc 311, distributed radially thereafter, with the side of the guide groove 315 facing away from the rotating component 1 being open. The connecting plate 312 is slidably disposed within the guide groove 315. A traction hole 316 is formed at the end of the connecting plate 312 near the axis of the connecting disc 311. The traction hole 316 penetrates the connecting plate 312 along the axial direction of the connecting disc 311. In this embodiment, the diameter of the traction hole 316 is larger than the diameter of the cable.

[0035] Reference Figure 3 The limiting component 2 includes a limiting ring 21 coaxially fixed on the rotating component 1. The limiting ring 21 has several guide holes 22. These guide holes 22 are evenly distributed along the circumference of the limiting ring 21. In this embodiment, four guide holes 22 are provided. When the connecting plate 312 is in its initial state, the distance between the axis of the traction hole 316 and the axis of the connecting disk 311 is less than the distance between the axis of the guide hole 22 and the axis of the limiting ring 21.

[0036] The initial position of the traction hole 316 is closer to the rotation axis than that of the guide hole 22. This means that the cable leading from the guide hole 22 converges obliquely from the outside to the inside when it reaches the traction hole 316. This converging path forces each cable to be in a "pre-twisted" state before entering the traction hole 316, meaning that there is an angle between the cable axis and the equipment's rotation axis. Furthermore, this twisting state is the same as the convergence state of each cable during the actual twisting after pre-twisting, thus improving the twisting quality.

[0037] Reference Figures 3 to 6 The fastening assembly 4 includes a trigger 41, a locking member 42, and a drive member 43. The drive member 43 is mounted on the drive shaft 313 and connected to the trigger 41, driving the trigger 41 to move axially along the drive shaft 313. The locking member 42 is slidably mounted on the connecting plate 312. After the cable is passed through the limiting assembly 2 and the cable end is inserted into the traction hole 316, the drive member 43 drives the trigger 41 to move towards the connecting plate 311, causing the trigger 41 to abut against the locking member 42. This, in turn, drives the locking member 42 to fasten the cable within the traction hole 316.

[0038] Reference Figure 4 and Figure 5 The connecting plate 312 has a first groove 317 and a second groove 318. The first groove 317 extends axially along the connecting plate 311 and passes through the connecting plate 312. The second groove 318 extends radially along the connecting plate 311 and communicates with the first groove 317 and the traction hole 316, respectively. The locking member 42 includes a limiting plate 421 and a pressing rod 422. The limiting plate 421 and the pressing rod 422 are slidably disposed in the first groove 317 and the second groove 318, respectively. The side of the limiting plate 421 near the pressing rod 422 is set as an inclined surface. When the limiting plate 421 moves away from the trigger member 41, it abuts against the pressing rod 422 through the inclined surface, driving the pressing rod 422 to move toward the axis of the connecting plate 311, thereby increasing the clamping force of the pressing rod 422 on the cable in the traction hole 316.

[0039] The end of the pressure rod 422 near the traction hole 316 has an inclined surface, facing the direction in which the cable enters the traction hole 316. An elastic element 3 44 is provided between the limiting plate 421 and the connecting plate 312, configured to drive the limiting plate 421 towards the trigger element 41. In this embodiment, the elastic element 3 44 is a spring. In this embodiment, four cables are led out from the rotating assembly 1. Four guide grooves 315 and four connecting plates 312 are correspondingly provided on the connecting plate 311. The four guide grooves 315 and four connecting plates 312 are evenly arranged along the circumference of the connecting plate 311. A set of locking elements 42 is provided on each connecting plate 312. The trigger element 41 simultaneously abuts against multiple limiting plates 421.

[0040] The operator passes the cable through the limiting member 45 and then inserts the cable end into the traction hole 316. The cable end abuts against the inclined surface of the pressure rod 422, causing the pressure rod 422 to move away from the traction hole 316. This allows the cable to move into the area corresponding to the pressure rod 422 within the traction hole 316. After all four cables are inserted into the traction holes 316, the driving member 43 drives the trigger member 41 to move towards the connecting plate 311, causing the trigger member 41 to simultaneously abut against multiple limiting plates 421. The limiting plates 421 then abut against the pressure rod 422, driving the pressure rod 422 towards the traction hole 316. This increases the clamping force on the cable within the traction hole 316, preventing the cable from slipping out of the traction hole 316 during twisting and affecting normal operation.

[0041] Reference Figure 6 and Figure 7 The fastening assembly 4 also includes limiting members 45. The limiting members 45 include rack one 451 and rack two 452. Rack one 451 and rack two 452 are respectively connected to the trigger member 41 and the connecting plate 312. In this embodiment, four sets of limiting members 45 are provided, and the four sets of limiting members 45 correspond one-to-one with the four connecting plates 312. When the trigger member 41 approaches the connecting plate 312, rack one 451 and rack two 452 engage, limiting the radial position of the connecting plate 312 on the connecting disc 311.

[0042] Reference Figures 3 to 7 The trigger element 41 includes a connecting ring 411, an extension rod 412, a positioning plate 413, and a transmission plate 414. The connecting ring 411 is coaxially sleeved on the drive shaft 313 and slides along the axial direction of the drive shaft 313. The extension rod 412 is fixedly disposed at one end of the connecting ring 411 near the connecting plate 312. The positioning plate 413 is fixedly disposed at one end of the extension rod 412 away from the connecting ring 411. A cavity is formed inside the drive shaft 313, and a through groove communicating with the cavity is formed on the drive shaft 313. The drive element 43 is fixedly disposed inside the cavity of the drive shaft 313. The transmission plate 414 is connected to the output end of the drive element 43, that is, the transmission plate 414 slides along the axial direction of the drive shaft 313 inside the cavity of the drive shaft 313. The transmission plate 414 is fixedly connected to the connecting ring 411 through the through groove on the drive shaft 313. In this embodiment, the drive component 343 is configured as a cylinder.

[0043] In this embodiment, four extension rods 412 are provided, and the four extension rods 412 are evenly distributed along the circumference of the connecting ring 411. This improves the stability and firmness of the connection between the positioning plate 413 and the connecting ring 411. The positioning plate 413 is cross-shaped. That is, in this embodiment, the positioning plate 413 is composed of four extension plates 415 that are adapted to four guide grooves 315. A clearance groove 319 is provided on the side of the drive shaft 313 near the connecting plate 311. The clearance groove 319 is adapted to the shape of the positioning plate 413. That is, the positioning plate 413 is slidably disposed in the clearance groove 319.

[0044] Reference Figure 7 Each of the multiple extension plates 415 on the positioning plate 413 has a receiving groove 416. The receiving grooves 416 extend radially along the connecting ring 411. The trigger member 41 also includes a trigger plate 46, which is slidably disposed within the receiving groove 416 along the axial direction of the connecting ring 411. A limiting hole penetrating the positioning plate 413 is provided within the receiving groove 416. A guide rod 461 adapted to the limiting hole is fixedly disposed on the side of the trigger plate 46 opposite to the connecting plate 312. The guide rod 461 extends through the limiting hole to the side of the positioning plate 413 opposite to the connecting plate 312. A baffle 462 is provided at the end of the guide rod 461 away from the trigger plate 46. The baffle 462 extends radially toward the connecting ring 411. An elastic element 463 is disposed between the baffle 462 and the positioning plate 413, and the elastic element 463 is configured to drive the baffle 462 to move toward the positioning plate 413. That is, the trigger plate 46 is driven to move closer to the connecting plate 312. In this embodiment, four trigger plates 46 are provided. And the four trigger plates 46 are correspondingly arranged in the receiving grooves 416 on the four extension plates 415 on the positioning plate 413.

[0045] Reference Figures 4 to 7 Rack 1 451 is disposed on both sides of the receiving groove 416 on the extension plate 415. Rack 2 452 is disposed on the connecting plate 312 at the position corresponding to rack 1 451. Both rack 1 451 and rack 2 452 extend radially along the connecting plate 311. In this embodiment, two racks 1 451 and rack 2 452 are disposed on one extension plate 415 and one connecting plate 312 respectively.

[0046] By configuring the elastic element 463, when the driving element 43 drives the positioning plate 413 towards the connecting plate 312, the trigger plate 46 first abuts against the limiting plate 421, and then the limiting plate 421 abuts against the pressing rod 422 to secure the cable in the traction hole 316. As the positioning plate 413 continues to move, it overcomes the elastic force of the elastic element 463, causing rack 451 to mesh with rack 452, restricting the position of the connecting plate 312. This allows the driving element 43 to control rack 451 to move away from rack 452 in subsequent operations. After releasing the restriction on the connecting plate 312, the trigger plate 46 remains abutting against the limiting plate 421, keeping the cable in the traction hole 316 secure.

[0047] Reference Figure 5 A connecting shaft 423 is fixedly mounted on the side of the limiting plate 421 near the trigger plate 46. The axial direction of the connecting shaft 423 is perpendicular to the sliding direction of the limiting plate 421. A rolling column 424 is coaxially rotatably mounted on the connecting shaft 423. When the trigger plate 46 approaches the limiting plate 421, the trigger plate 46 abuts against the rolling column 424. When the connecting plate 312 moves radially along the connecting disc 311, the rolling column 424 reduces friction between it and the trigger plate 46.

[0048] Reference Figure 4 and Figure 6 An elastic element 36 is provided between the connecting plate 312 and the connecting disk 311. The elastic element 36 is configured to drive the connecting plate 312 away from the axis of the connecting disk 311. In this embodiment, the elastic element 36 is a spring. After the pre-twisting is completed and the cable is removed from the traction hole 316, the connecting plate 312 is reset by the action of the elastic element 36.

[0049] Reference Figure 1 and Figure 2 A guide groove 331 extending axially along the rotating assembly 1 is provided on the guide plate 33. A sliding block 34 is slidably disposed within the guide groove 331. A lead screw 37 is rotatably disposed within the guide groove 331. The axial direction of the lead screw 37 is parallel to the extending direction of the guide groove 331. A drive member 332 is fixedly disposed on the side of the guide plate 33 away from the rotating assembly 1. The output end of the drive member 332 is connected to the lead screw 37 to drive the lead screw 37 to rotate. A through hole adapted to the lead screw 37 is provided on the sliding block 34. The lead screw 37 passes through the through hole of the sliding block 34. The lead screw 37 and the sliding block 34 are in a helical sliding fit. That is, the rotation of the lead screw 37 causes the sliding block 34 to move axially along the lead screw 37.

[0050] When the cable is inserted into the traction hole 316, the connecting piece 31 can be moved closer to the limiting component 2 by the drive component 332. This facilitates the operator in installing the cable into the traction hole 316 and reduces the distance between the connecting piece 31 and the limiting component 2. This prevents the cable between the connecting piece 31 and the limiting component 2 from drooping under its own weight, which would make it difficult for the operator to install the cable into the traction hole 316. Furthermore, if all four cables are not fully installed into the traction hole 316, the cables already installed in the traction hole 316 are prone to detaching from the traction hole 316 under their own weight.

[0051] Reference Figure 2 and Figure 9 A winding assembly 5 is slidably mounted on the guide plate 33. The winding assembly 5 is positioned between the traction assembly 3 and the limiting assembly 2. A drive plate 61, perpendicular to the extending direction of the guide plate 33, is fixedly mounted on the guide plate 33. A cavity is formed inside the drive plate 61, and a lead screw 62 is rotatably mounted within the cavity. The axial direction of the lead screw 62 is perpendicular to the extending direction of the guide plate 33. A drive component 63 is fixedly mounted on the side of the drive plate 61. The output end of the drive component 63 is connected to the lead screw 62 to drive the lead screw 62 to rotate.

[0052] The winding assembly 5 includes a limiting block 51, a positioning block 52, a rotating shaft 53, and a winding reel 54. The limiting block 51 is slidably disposed in a cavity on the drive plate 61. The limiting block 51 and the lead screw 62 are helically slidably connected. That is, rotating the lead screw 62 allows the limiting block 51 to move axially along the lead screw 62. A cavity is formed in the limiting block 51, and the positioning block 52 slides up and down within this cavity. A driving component 55 is disposed within the cavity of the limiting block 51. The output end of the driving component 55 is fixedly connected to the bottom of the positioning block 52, driving the positioning block 52 to move up and down relative to the limiting block 51. The rotating shaft 53 is rotatably disposed on the positioning block 52. The winding reel 54 is coaxially disposed on the rotating shaft 53. The positioning reel rotates synchronously with the rotating shaft 53. A driving component 56 is disposed on the positioning block 52 to drive the rotating shaft 53 to rotate.

[0053] Reference Figure 9 A connecting block 57 is fixedly mounted on the guide plate 33. The connecting block 57 corresponds to the limiting block 51, meaning they are positioned on opposite sides of the lead screw 37. A cavity is formed within the connecting block 57. A load-bearing block 58 is slidably mounted within this cavity. The load-bearing block 58 has a through hole adapted to the rotating shaft 53. Fastening bolts 59 are mounted on the connecting block 57 to fix its position.

[0054] When the sliding block 34 is moved, i.e., when the cable needs to be installed on the connector 31, the limit block 51 is controlled by the drive component 63 to move the winding assembly 5 out of the moving path of the sliding block 34. After the cable installation is completed, when the cable needs to be pre-stretched, the rotating shaft 53 is controlled by the drive component 63 to insert into the through hole on the load-bearing block 58. Then, the positioning block 52 is controlled by the drive component 55 to move the winding reel 54 towards the pre-stretched cable.

[0055] Reference Figure 9 A winding groove 541 is provided on the winding reel 54, and a fastening clip 542 is provided on the winding groove 541. A through hole adapted to the fastening clip 542 is provided on the winding reel 54. When the winding reel 54 is moved to the pre-stretched cable, the cable is positioned within the winding groove 541. The operator secures the cable to the winding reel 54 using the fastening clip 542. Then, the trigger plate 46 is moved away from the limit plate 421 by the drive component 3 43, allowing the cable to be removed from the traction hole 316. This completes the transfer of the cable from the connector 31 to the winding reel 54.

[0056] Reference Figure 1 and Figure 9 A guide assembly 7 is provided between the winding assembly 5 and the limiting assembly 2. The guide assembly 7 includes guide blocks 71 and a third lead screw 72 slidably disposed on both sides of the first lead screw 37. A second drive plate 81 perpendicular to the extending direction of the guide plate 33 is fixedly disposed on the guide plate 33. A cavity is formed on the second drive plate 81. The third lead screw 72 is rotatably disposed in the cavity of the second drive plate 81. The third lead screw 72 is slidably helically connected to the two guide blocks 71 respectively. In this embodiment, the third lead screw 72 is provided with helical grooves with opposite helical directions. The guide blocks 71 are helically slidably connected to the two helical grooves respectively. So that when the third lead screw 72 rotates, the two guide blocks 71 synchronously move closer to or further away from the cable. A semi-circular groove is formed at the upper end of each of the two guide blocks 71. So that when the two guide blocks 71 abut against each other, the semi-circular grooves on the two guide blocks 71 form a circular hole coaxial with the rotating assembly 1. The twisted cable is passed between the grooves of the two guide blocks 71. In this embodiment, the lead screw is driven to rotate by the operator manually rotating the lead screw.

[0057] Specific work process: In the initial stage, the first lead screw 37 is rotated by the second drive component 332, causing the sliding block 34 to move towards the limiting component 2. This moves the connecting plate 312 closer to the limiting component 2. The operator manually passes one side of the cable through the limiting component 2 and inserts it into the corresponding traction hole 316. The third drive component 43 drives the positioning plate 413 to move towards the connecting plate 312, so that the trigger plate 46 presses against the rolling column 424, and the limiting plate 421 presses against the pressing rod 422 to clamp the cable in the traction hole 316. At the same time, the meshing of the first rack 451 with the corresponding second rack 452 restricts the movement of the connecting plate 312. The first lead screw 37 is rotated in the opposite direction, moving the sliding block 34 to the initial position. The first drive component 32 drives the drive shaft 313 to rotate, causing multiple connecting plates 312 to rotate simultaneously, pre-twisting the cable between the connecting plate 312 and the limiting component 2. During the stranding process, after the multi-strand cable completes the predetermined stranding length, the control positioning plate 413 moves away from the connecting plate 312 until rack one 451 and rack two 452 disengage. Under the action of the cable stranding force, the connecting plate 312 is driven to move axially toward the connecting reel 311. After the cable pre-stretching is completed, the drive unit five 55 and drive unit six 56 move the take-up reel 54 to the pre-stretched cable, and the cable is fixed to the take-up reel 54 by the fastening buckle 542. Then, the control trigger plate 46 disengages from the rolling column 424 and contacts the pressure rod 422 to fix the cable in the traction hole 316, so that the cable can be removed from the traction hole 316. Finally, the control two guide blocks 71 move closer to the pre-stretched cable, and the cable is limited by the circular through hole formed by the two semi-circular grooves on the guide block 71. Then, the rotating assembly 1 is activated to twist the cable, while the drive shaft 313 drives the winding reel 54 to rotate, so as to wind the twisted cable onto the winding reel 54.
