Description

Technical Field

[0001] This invention relates to the field of power processing technology, specifically to a cable stranding device and a stranding method for processing flat transposed conductors. Background Technology

[0002] Transposed conductors are made by arranging multiple enameled flat copper (aluminum) wires in two rows and transposing them sequentially and evenly using a double-helix winding transposition method (cross transposition method). This transposition is called the transposition pitch or strand pitch.

[0003] Transposition pitch refers to the distance between two or more wires during the stranding process, that is, the degree of interlacing between the wires. The size of the strand pitch affects the strength, flexibility, and appearance of the wire. By properly designing the transposition pitch, electromagnetic interference in the line can be effectively balanced, and the asymmetry of current distribution can be reduced, thereby improving transmission efficiency and reducing losses.

[0004] When stranding transposed conductors with different transposition pitches, existing stranding machines typically adjust the pitch using a pitch lever on the machine. Generally, rotating the lever to the left decreases the pitch, while rotating it to the right increases it. However, in practice, adjusting the pitch using the pitch lever is not precise enough, and the lever is prone to loosening during the stranding process. This results in different transposition pitches existing on the stranded conductors, ultimately affecting the quality of the transposed conductors. Summary of the Invention

[0049] The winding assembly further comprises a lifting piece 101 fixedly arranged in the cabinet 1, the winding roller 2 is installed on the lifting piece 101, and the rotating shaft of the winding roller 2 is connected with a linkage rod 6 rotatably installed on the lifting piece 101 through a belt, the linkage rod 6 is connected with a driving cylinder 8 rotatably installed in the cabinet 1 through a bevel gear set 7;

[0050] The bevel gear set 7 comprises a first bevel gear and a second bevel gear, the first bevel gear is coaxially fixedly connected with the linkage rod 6, and the second bevel gear is coaxially fixedly connected with the driving cylinder 8;

[0051] In detail, please refer to Figure 2 、 Figure 3 、 Figure 5 , the above-mentioned lifting piece 101 is arranged in the width direction of the cabinet 1, each group of lifting pieces 101 is provided with a rotating rod 102, the winding roller 2 is coaxially fixedly connected with the rotating rod 102, and the rotating rod 102 on one group of lifting pieces 101 is fixedly connected with the output shaft of the motor fixedly arranged on the lifting piece 101;

[0052] Preferably, a longitudinal piece 3 is further fixedly arranged between the winding roller 2 and the rotating disc 5, the longitudinal piece 3 is provided with a guide roller set 301, and the longitudinal piece 3 is provided with a plastic piece 302, the plastic piece 302 is a square structure, in actual wire arrangement, the wires on the two groups of wire rollers 21 are first pulled through the through grooves 502 arranged on the rotating disc 5, then pass through the guide roller set 301 and the plastic piece 302, and are wound on the winding roller 2, then the motor is started, at this time, the output shaft of the motor can drive the winding roller 2 to continuously rotate in the same direction, at the same time, the rotating disc 5 can also rotate, combined with the rotation of the rotating disc 5 and the pulling of the winding roller 2, the two wires between the guide roller set 301 can be arranged and twisted into one, then the twisted wire can pass through the plastic piece 302, when passing through the plastic piece 302, the groove wall of the plastic piece 302 can extrude and plasticize the twisted wire, so that the twisted wire can form a twisted wire (also known as transposed wire) with uniform length, width and height, these regular transposed wires will be finally wound on the winding roller 2, so as to be used for subsequent processing.

[0053] Further, please refer to Figure 2 ,Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 A cable twisting device further comprises a linkage mechanism arranged in the cabinet 1, which comprises a switching assembly and a variable speed assembly. The switching assembly is connected to the variable speed assembly, the rotating disc 5 and the winding roller 2. When the winding roller 2 rotates, the rotating disc 5 rotates, and two groups of wires can be combined into one. The switching assembly switches the connection state of the variable speed assembly, the rotating disc 5 and the winding roller 2, and adjusts the transmission ratio between the rotating disc 5 and the winding roller 2, so that the rotating disc 5 and the winding roller 2 cooperate to weave transposed wires with different transposition pitches.

[0054] The variable speed assembly comprises a transmission structure and a linkage member. The transmission structure comprises a gear set rotatably installed in the cabinet 1. The gear set is equidistantly arranged along the length direction of the cabinet 1. Each gear set comprises a set of mutually meshing main gears 14 and slave gears 15. The radii of the main gears 14 in the multiple groups are the same, and the radii of the slave gears 15 in the multiple groups increase sequentially.

[0055] For example, refer to Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 The gear set is equidistantly arranged along the length direction of the cabinet 1. The main gears 14 are coaxially fixedly arranged with a plug-in sleeve 1401. From the direction from the winding roller 2 to the rotating disc 5, the radii of the slave gears 15 increase sequentially. Therefore, the transmission ratio between the main gears 14 and the slave gears 15 in the three groups of gear sets decreases sequentially.

[0056] In particular, the proportional relationship between the main gears 14 and the slave gears 15 is set according to the transposition pitch value of the twisted wire. Under the cooperation of the main gears 14 and the slave gears 15 with the specified proportion, the transposition pitch of the finally prepared transposed wire is more accurate.

[0057] The linkage member comprises a linkage sleeve 13 rotatably installed in the cabinet 1. The linkage sleeve 13 is equidistantly arranged along the length direction of the cabinet 1. Each linkage sleeve 13 is connected to the corresponding slave gear 15 through a belt. The radii of the three linkage sleeves 13 are equal, and the transmission ratio between the linkage sleeves 13 and the slave gears 15 is one to one. In particular, the spacing between the linkage sleeves 13 is the same as the spacing between the main gears 14.

[0058] In combination with the above, by using the switching assembly, gear sets with different transmission ratios can be selected to connect the rotating disc 5 and the winding roller 2, thereby changing the rotating speed of the rotating disc 5 while keeping the rotating speed of the winding roller 2 unchanged, so that the cooperation between the rotating disc 5 and the winding roller 2 can produce transposed wires with different transposition pitches.

[0059] Further, referring to Figure 2 、 Figure 3 、 Figure 8 、 Figure 10 、 Figure 11 , the switching assembly comprises a driving rod 17 and a driven rod 16 rotatably installed in the cabinet 1, one end of the driving rod 17 is inserted into the driving cylinder 8 rotatably installed on the cabinet 1, and the other end is in sliding connection with the main gear 14, one end of the driven rod 16 is inserted into the driven cylinder 12, and the other end is in sliding connection with the linkage cylinder 13, and the driving rod 17 and the driven rod 16 are fixedly connected by a connecting rod 9, specifically, both ends of the connecting rod 9 are fixedly provided with a sleeve ring, and two sets of sleeve rings are sleeved on the driven rod 16 and the driving rod 17, respectively, and the connecting rod 9 is in sliding connection with a guide 10 fixedly arranged in the cabinet 1, and under the limitation of the guide 10, the connecting rod 9 can only slide along the length direction of the cabinet 1;

[0060] In particular, referring to Figure 8 、 Figure 10 、 Figure 11 , the front and rear ends of the driven rod 16 are equally spaced around the circumferential direction and are provided with two sets of second protruding columns 1601, specifically, the second protruding column 1601 at one end of the driven rod 16 towards the driven cylinder 12 is slidingly arranged in the second groove 1201 formed on the inner wall of the driven cylinder 12, and the second protruding column 1601 at the other end of the driven rod 16 is adapted to the matching hole 1301 coaxially formed on the linkage cylinder 13, and under the cooperation of the second protruding column 1601 and the second groove 1201 and the matching hole 1301, the linkage cylinder 13, the driven rod 16 and the driven cylinder 12 can rotate synchronously;

[0061] and the front and rear ends of the driving rod 17 are equally spaced around the circumferential direction and are provided with two sets of first protruding columns 1701, specifically, the first protruding column 1701 at one end of the driving rod 17 towards the driving cylinder 8 is slidingly arranged in the first groove 801 formed on the inner wall of the driving cylinder 8, and the first protruding column 1701 at the other end is adapted to the plug-in cylinder 1401 fixedly arranged on the main gear 14, and under the cooperation of the first protruding column 1701 and the first groove 801 and the plug-in cylinder 1401, the main gear 14, the driving rod 17 and the driving cylinder 8 can rotate synchronously;

[0062] In the initial state, the driven rod 16 links the linkage cylinder 13 near the winding roller 2 with the driven cylinder 12, and the driving rod 17 connects the main gear 14 near the winding roller 2 with the drive cylinder 8, as shown above. Figure 8 As shown, in this state, the driven rod 16 travels the shortest distance into the driven cylinder 12, while the driving rod 17 travels the longest distance into the drive cylinder 8. (See diagram below.) Figure 7 At this time, the transmission ratio between turntable 5 and winding roller 2 remains at its maximum.

[0063] When the transposed wire is being braided (the wire on the wire roller 21 has been wound onto the winding roller 2), the motor is started. The output shaft of the motor can drive the winding roller 2 and the rotating rod 102 to rotate continuously in the same direction. At the same time, the continuously rotating rotating rod 102 can drive the drive cylinder 8 to rotate continuously in the same direction with the cooperation of the belt, the linkage rod 6 and the bevel gear set 7. Then, the driving rod 17 can drive the main gear 14 to rotate synchronously with the drive cylinder 8, thereby forcing the driven gear 15 to rotate in the opposite direction to the main gear 14. Then, the linkage cylinder 13, which is linked with the driven gear 15, can drive the turntable 5 to rotate with the connection of the driven rod 16. At this time, through the cooperation between the winding traction of the winding roller 2 and the rotation and twisting of the turntable 5, the two sets of wires can be twisted into one strand. Finally, when it is wound onto the winding roller 2, a twisted wire is obtained.

[0064] According to actual usage requirements, when the connecting rod 9 is slid a certain distance along the length of the housing 1 toward the turntable 5, it can drive the driving rod 17 and the driven rod 16 to move simultaneously. During the movement, due to the cooperation of the elastic locking structure on the connecting rod 9, the driving rod 17 and the driven rod 16 can simultaneously engage with the next set of gears and maintain a stable state. At this time, the transmission ratio between the turntable 5 and the winding roller 2 becomes smaller. When the winding roller 2 works, the transposition pitch of the stranded wire produced in cooperation with the turntable 5 will increase, thereby producing a transposition wire with a larger transposition pitch.

[0065] For details, please refer to Figure 7 , Figure 8 , Figure 10 , Figure 11 The elastic locking structure includes a fixed sleeve 11 disposed on the connecting rod 9, a spring 20 slidably disposed inside the fixed sleeve 11, one end of the spring 20 abutting against the fixed sleeve 11, and the other end abutting against the insertion rod 19 slidably disposed inside the fixed sleeve 11. A pulley is rotatably mounted on the end of the insertion rod 19 away from the spring 20. The pulley cooperates with a locking member fixedly disposed inside the housing 1 to fix the position of the connecting rod 9.

[0066] In detail, the spring 20 is always in compression, and the spring 20 in compression pushes the insertion rod 19 to have a tendency to move towards the locking member, at this time, the insertion rod 19 can lock the position of the connecting rod 9 under the cooperation of the locking member and the spring 20 storing elastic potential energy, that is, maintain the connection state of the driving rod 17 and the driven rod 16 with the main gear 14 and the driven gear 15, so that when the rotating rod 102 rotates, the rotating disc 5 can be driven to rotate simultaneously, thereby completing the twisting operation of the two wires.

[0067] Specifically, please refer to Figure 11 The locking member includes a trigger block 18 fixedly arranged in the cabinet 1, a plurality of sets of locking grooves 1801 are equidistantly arranged on the trigger block 18, a first inclined surface 1802 and a second inclined surface 1803 are arranged between adjacent two sets of the locking grooves 1801, and the first inclined surface 1802 and the second inclined surface 1803 are symmetrically arranged.

[0068] In particular, the plurality of sets of locking grooves 1801 and the first inclined surface 1802 and the second inclined surface 1803 form a shape structure similar to a wave, in the initial state, the pulley at the end of the insertion rod 19 is combined with the locking groove 1801 close to the winding roller 2, when it is necessary to reduce the transmission ratio between the rotating disc 5 and the rotating rod 102, the connecting rod 9 is pulled to move away from the winding roller 2, in the moving process, the pulley slides along the first inclined surface 1802, when sliding, the first inclined surface 1802 produces contact and extrusion to the pulley, which can force the insertion rod 19 to rise, thereby further extruding the spring 20, so that the elastic potential energy stored in the spring 20 is increased, until the pulley passes through the symmetry axis of the first inclined surface 1802 and the second inclined surface 1803, the spring 20 releases the elastic potential energy, which can drive the insertion rod 19 and the connecting rod 9 to automatically and quickly continue to move away from the winding roller 2, at this time, the pulley slides along the second inclined surface 1803, until the pulley is combined with the next set of locking grooves 1801, the position of the connecting rod 9 is fixed.

[0069] By adjusting the position of the connecting rod 9, the driving rod 17 and the driven rod 16 can be driven to combine with the next set of main gear 14 and the linkage cylinder 13, thereby changing the transmission ratio between the rotating disc 5 and the winding roller 2, and then different length of the transposed structure of the stranded conductor can be prepared according to the actual demand. After the transmission ratio is adjusted, the cooperation between the pulley and the locking groove 1801 can lock the connection between the rotating disc 5 and the winding roller 2 and the transmission assembly, so that the rotating disc 5 and the winding roller 2 always cooperate with the specified transmission ratio (especially when adjusting the transmission ratio, it needs to be adjusted in the stopped state, so when moving the connecting rod 9, if the driving rod 17 and the driven rod 16 cannot directly combine with the main gear 14 and the linkage cylinder 13, slightly rotating the main gear 14 or the linkage cylinder 13 can complete the combination of the driving rod 17 and the driven rod 16 with the main gear 14 and the linkage cylinder 13). Compared with the traditional stranding equipment, the mutual cooperation between the transmission assembly and the switching assembly can more simply and quickly adjust the transmission ratio between the rotating disc 5 and the winding roller 2, and then the stranded conductor with different transposed pitch can be prepared. Under the cooperation of the transmission assembly and the switching assembly, the adjustment of the ratio during the adjustment process is more accurate, and then the stranded conductor obtained finally is more regular, thereby improving the quality of the transposed conductor. By accurately controlling the transposed pitch of the transposed conductor, the electric field distribution of the power system can be more uniform, the failure rate of the power system can be reduced, and the reliability of the power system can be improved.

[0070] A flat transposed conductor processing stranding method is also proposed, which uses the cable stranding equipment as described above, and includes the following steps: step one: first, install two sets of wire rollers 21 on the storage rack 22, and then pass the wires on the wire rollers 21 through the rotating disc 5 and the longitudinal piece 3, so that the ends of the wires are wound and connected with the winding roller 2;

[0071] Step two: according to the actual demand, drive the connecting rod 9 to slide relative to the cabinet 1. During the sliding process, the connecting rod 9 can drive the driven rod 16 and the driving rod 17 to slide synchronously, and can change the connection state of the transmission assembly and the rotating disc 5 and the winding roller 2, thereby changing the transmission ratio between the rotating disc 5 and the winding roller 2;

[0072] Step three: start the motor, and the winding roller 2 rotates.
