During the process of winding flat steel wire onto a pipe or cable to form flat steel wire armor, the first and second toothed rings are used to adjust the deflection and twist angles of the flat steel wire, respectively, causing the flat steel wire to deform before winding onto the pipe, and adjusting the tangential angle between the flat steel wire and the pipe according to the required angle, so that the flat steel wire naturally forms a spiral shape and winds onto the pipe, ensuring the quality of the flat steel wire winding. This invention improves upon existing flat steel wire winding methods that easily encounter problems such as uneven spacing of flat steel wires, overlapping of some flat steel wires, high stress during winding leading to twisting and unevenness of the flat steel wire, and warping and deflection of the flat steel.

Description

Technical Field

[0001] This invention relates to the field of flat wire winding machine technology, and more specifically to a pre-twisting forming device for a flat wire winding machine. Background Technology

[0002] Steel wire winding machines mainly use metal monofilaments (primarily round steel wire, plastic-coated steel wire, etc.) to armor submarine power cables, power and optical communication composite cables, or umbilical cables, protecting and enhancing the mechanical strength, stability, and safety of the cables or pipes.

[0003] However, when winding flat steel wire onto pipes or cables, uneven spacing and irregularities frequently occur, resulting in poor quality of the wrapped armor. Furthermore, because the output posture of the flat steel wire is fixed and its relative posture to the pipe cannot be adjusted, the winding quality problems are difficult to eliminate. Summary of the Invention

[0004] The technical problem solved by this invention is that uneven spacing and irregularity of flat steel wires often occur during winding, resulting in poor quality of the flat steel wire winding armor. Furthermore, because the output posture of the flat steel wire is fixed and its relative posture to the pipeline cannot be adjusted, the winding quality problem is difficult to eliminate.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A pre-twisting forming device for a flat steel wire winding machine, comprising:

[0007] Cable output winch;

[0008] Several fixed seats are fixedly installed on the outer side of the cable outlet winch, and the several fixed seats are evenly distributed along the circumference of the cable outlet winch. A steel wire channel is opened in the center of each fixed seat.

[0009] A deflector wheel is rotatably mounted on a fixed base. The side of the deflector wheel closest to the center of the cable outlet winch is a transmission part, and the other side is a connecting part.

[0010] A connecting plate, one end of which is fixedly connected to the connecting part, and the other end of which is provided with a deflection guide roller group;

[0011] The first gear ring is rotatably connected to the cable outlet winch, and the first gear ring is coaxially arranged with the cable outlet winch. The outer circumference of the first gear ring is provided with transmission teeth that mesh with the transmission part.

[0012] A first power component is used to drive the first gear ring to rotate.

[0013] As a further embodiment of the present invention: a torsion seat is fixedly provided on the connecting plate between the deflection wheel and the deflection guide roller group; a hollow shaft is rotatably provided inside the torsion seat; a torsion wheel is fixedly sleeved at one end of the hollow shaft near the deflection wheel, and a torsion guide roller group is installed at the other end; a second gear ring is rotatably provided on the cable outlet winch; the outer circle of the second gear ring meshes with the torsion wheel; and a second power component is used to drive the second gear ring to rotate.

[0014] As a further embodiment of the present invention: a plurality of support shafts are fixedly provided on the outer side of the cable outlet winch, the support shafts are evenly distributed along the circumference of the cable outlet winch, a support roller is rotatably sleeved on the support shaft, and a support groove is formed on the outer circumference of the support roller, the size of the support groove being matched with the size of the first gear ring.

[0015] As a further embodiment of the present invention: the deflection guide roller group includes a guide roller frame, a flat guide wheel and a grooved guide wheel. The flat guide wheel and the grooved guide wheel are respectively rotatably mounted on the guide roller frame. The flat guide wheel is tangent to the outer circular surface of the grooved guide wheel, and the grooved guide wheel is located on the side close to the center of the cable outlet winch.

[0016] As a further aspect of the present invention: the first power assembly includes a power source, a drive shaft and a drive wheel. The power source is fixedly mounted on the cable outlet winch and is driven by the drive shaft. The drive wheel is fixedly mounted on the drive shaft and is connected to the first gear ring in a transmission connection.

[0017] As a further aspect of the present invention: a stabilizing seat is fitted around the drive shaft near the drive wheel, the stabilizing seat is fixedly connected to the cable outlet winch, and a bearing is provided between the stabilizing seat and the drive shaft.

[0018] As a further embodiment of the present invention: a steel wire sleeve is fixedly installed inside the cable outlet winch, one end of the steel wire sleeve is connected to the fixed seat, and an inlet sleeve is provided at the other end of the steel wire sleeve.

[0019] A pre-twisting forming device for a flat steel wire winding machine according to the present invention has at least one of the following technical effects:

[0020] During the process of winding flat steel wire onto pipes or cables to form flat steel wire armor, the first and second toothed rings are used to adjust the deflection and twist angles of the flat steel wire, respectively. This causes the flat steel wire to deform before winding onto the pipe and adjusts the tangential angle between the flat steel wire and the pipe according to the required angle, allowing the flat steel wire to naturally form a spiral shape and wind onto the pipe, ensuring the quality of the flat steel wire winding. This improves upon existing flat steel wire winding methods that often result in uneven spacing of the flat steel wires, overlapping of some flat steel wires, high stress during winding leading to twisting and unevenness of the flat steel wires, and warping and deflection of the flat steel.

[0036] Please see Figure 1-9 As shown, the present invention is a pre-twisting forming device for a flat steel wire winding machine, comprising: a cable outlet winch 1, a fixed base 2, a deflecting wheel 3, a connecting plate 4, a deflecting guide roller group 5, a first gear ring 6, and a first power component. The fixed base 2 is fixedly disposed on the outer side of the cable outlet winch 1, and several fixed bases 2 are evenly distributed along the circumference of the cable outlet winch 1. A steel wire channel is formed at the center of the fixed base 2. The deflecting wheel 3 is rotatably sleeved on the fixed base 2. The side of the deflecting wheel 3 closest to the center of the cable outlet winch 1 is a transmission part, and the other side is a connecting part. One end of the connecting plate 4 is fixedly connected to the connecting part, and the other end is provided with the deflecting guide roller group 5. The first gear ring 6 is rotatably connected to the cable outlet winch 1, and the first gear ring 6 is coaxially disposed with the cable outlet winch 1. The outer circular surface of the first gear ring 6 is provided with transmission teeth that mesh with the transmission part. The first power component is used to drive the first gear ring 6 to rotate.

[0037] Please see Figure 1-9 In one embodiment of the present invention, a pipe hole is provided at the center of the cable-out end winch 1 for conveying pipes through the pipe hole; the side of the cable-out end winch 1 corresponding to the pipe output is the outer side, and a plurality of steel wire guide roller groups are arranged around the pipe hole on the outer side of the cable-out end winch 1 for conveying flat steel wires, which are then wound around the pipe to strengthen the pipe. The guide roller group may include a guide roller frame, a flat guide wheel 13 and a grooved guide wheel 14. The flat guide wheel 13 and the grooved guide wheel 14 are respectively rotatably mounted on the guide roller frame. The flat guide wheel 13 and the grooved guide wheel 14 are arranged parallel to each other and their outer circular surfaces are tangent to each other. The grooved guide wheel 14 is located on the side close to the center of the cable-out end winch 1 (i.e., the pipe hole). The grooved guide wheel 14 has a groove on its outer circumference, which matches the groove of the flat steel wire. After the flat guide wheel 13 and the grooved guide wheel 14 are laid out, a gap (groove) corresponding to the flat steel wire is formed between them for the flat steel wire to pass through and for limiting the flat steel wire.

[0038] Please see Figure 1-9 In one embodiment of the present invention, the fixing seat 2 is fixedly disposed on the outer side of the cable outlet winch 1, and a plurality of fixing seats 2 are evenly distributed along the circumference of the cable outlet winch 1. A wire channel is provided in the center of the fixing seat 2 for the flat steel wire to pass through. Specifically, the cable outlet winch 1 may have a mounting hole, the outer diameter of the fixing seat 2 matches the mounting hole, and a mounting part is fixedly disposed on the outer side of the fixing seat 2. In use, one end of the fixing seat 2 is inserted into the mounting hole, and then the mounting part and the cable outlet winch 1 are fixedly connected by a bolt structure. Thus, the mounting hole plays a positioning role to ensure the installation accuracy of the fixing seat 2, and the multi-sided contact ensures the stability of the fixing seat 2. Furthermore, a steel wire sleeve 19 is fixedly installed inside the cable outlet winch 1. One end of the steel wire sleeve 19 can be fixedly connected to the cable outlet winch 1 by a bolt structure, and the other end can be provided with a sleeve part. The end of the fixing seat 2 can be provided with a docking end. The outer diameter of the docking end matches the inner diameter of the sleeve part, so that one end of the steel wire sleeve 19 is docked with the fixing seat 2 through the sleeve part and the docking end, thereby ensuring the stability of the steel wire sleeve 19 and the fixing seat 2. An inlet sleeve can be provided at the entry end of the steel wire sleeve 19 to separate the flat steel wire and reduce the wear between the flat steel wire and the steel wire sleeve 19.

[0039] Please see Figure 1-9In one embodiment of the present invention, the deflecting wheel 3 is rotatably mounted on the fixed base 2, and a bearing can be provided between the deflecting wheel 3 and the fixed base 2 to reduce relative motion resistance; the side of the deflecting wheel 3 near the center of the cable-out end winch 1 is a transmission part, which can be provided with a transmission gear structure; the other side is a connecting part, which can be configured as a planar structure for connection with the connecting plate 4. One end of the connecting plate 4 can be fixedly connected to the connecting part by a bolt structure, and the other end is provided with a deflecting guide roller group 5; the structure of the deflecting guide roller group 5 can be the same as the structure of the guide roller group described above, and its groove is aligned with the wire channel in the fixed base 2 for the passage of flat steel wire. The guide roller frame of the deflecting guide roller group 5 can be fixedly connected to the connecting plate 4 by a bolt structure.

[0040] Please see Figure 1-9 In one embodiment of the present invention, the first gear ring 6 is rotatably connected to the cable outlet winch 1, and the first gear ring 6 and the cable outlet winch 1 are coaxially arranged. The outer circumferential surface of the first gear ring 6 is provided with transmission teeth that mesh with the transmission part. The method of rotatably connecting the first gear ring 6 to the cable outlet winch 1 is not limited. An arc-shaped sliding groove can be formed on the cable outlet winch 1 / first gear ring 6, and a slider can be fixedly provided on the first gear ring 6 / cable outlet winch 1, forming a movable connection through the cooperation of the slider and the sliding groove. Alternatively, support rods can be fixedly provided on the cable outlet winch 1, and the inner ring of the first gear ring 6 can be sleeved on the outside of multiple support rods. Specifically, as an example, multiple support shafts are fixedly installed on the outer side of the cable-out end winch 1. The support shafts are evenly distributed along the circumference of the cable-out end winch 1. A support roller 12 is rotatably sleeved on the support shaft. A support groove is opened on the outer circumference of the support roller 12. The size of the support groove matches the thickness (axial direction) of the first gear ring 6. The multiple support rollers 12 are used to rotatably support the first gear ring 6. When the first gear ring 6 rotates, it drives the connecting plate 4 and the deflection guide roller group 5 to rotate around the axis of the fixed seat 2 by a corresponding angle after being driven by the deflection wheel 3. This changes the deflection angle of the flat steel wire when it is output through the deflection guide roller group 5. The cutting angle between the flat steel wire and the pipe can be adjusted as needed to ensure the flatness of the flat steel wire pipe surface winding.

[0041] Please see Figure 1-9In one embodiment of the present invention, the first power assembly is used to drive the first gear ring 6 to rotate. The first power assembly may include a power source 15, a drive shaft 16, and a drive wheel 17. The power source 15 may be fixedly disposed inside the cable outlet winch 1, and the power source 15 is driven by the drive shaft 16, which passes through the cable outlet winch 1. The drive wheel 17 is fixedly disposed on the drive shaft 16 and is drively connected to the first gear ring 6. Anti-slip textures may be provided on the inner wall of the first gear ring 6, and the outer circular surface of the drive wheel 17 contacts the inner circular surface of the first gear ring 6, thereby driving the first gear ring 6 to rotate. Preferably, transmission teeth may be provided on the inner wall of the first gear ring 6 between the two support rollers 12, and the drive wheel 17 contacts the inner wall of the first gear ring 6, so that the two mesh and transmit power. A stabilizing seat 18 is fitted around the drive shaft 16 near the drive wheel 17. The stabilizing seat 18 is fixedly connected to the cable outlet winch 1, and a bearing is provided between the stabilizing seat 18 and the drive shaft 16. The stabilizing seat 18 can effectively improve the stability of the drive shaft 16 and the drive wheel 17, thereby ensuring the accuracy when adjusting the deflection angle of the first gear ring 6.

[0042] Please see Figure 1-9In one embodiment of the present invention, a torsion seat 7 is fixedly disposed on the connecting plate 4 between the deflecting wheel 3 and the deflecting guide roller group 5. The torsion seat 7 can be fixedly connected to the connecting plate 4 by bolts. A hollow shaft 8 is rotatably disposed inside the torsion seat 7. The axis of the hollow shaft 8 matches the axis of the fixed seat 2 to form a connected wire channel for the flat steel wire to pass through. A torsion wheel 9 is fixedly sleeved at one end of the hollow shaft 8 near the deflecting wheel 3, and a torsion guide roller group 10 is installed at the other end of the hollow shaft 8. The structure of the torsion guide roller group 10 can be consistent with the structure of the guide roller group described above. The guide roller frame of the torsion guide roller group 10 is fixedly disposed on the hollow shaft 8. A second gear ring 11 is rotatably disposed on the cable outlet winch 1. The outer circle of the second gear ring 11 meshes with the torsion wheel 9. A second power component is used to drive the second gear ring 11 to rotate. The second gear ring 11 can adopt the same structure as the first gear ring 6 and be rotatably connected to the cable outlet winch 1 / first gear ring 6. The second gear ring 11 is supported by multiple support shafts and rollers 12. The structure of the second power assembly can be the same as that of the first power assembly to drive the second gear ring 11 to rotate. When the second gear ring 11 rotates, the hollow shaft 8 and the torsion guide roller group 10 are driven to rotate by the torsion wheel 9 meshing with the second gear ring 11. The torsion guide roller group 10 and the deflection guide roller group 5 work together to achieve pre-torsion deformation of the flat steel wire, change the angle of the flat steel wire, and thus allow the flat steel wire to naturally form a spiral and wind around the pipe, ensuring the quality of the flat steel wire winding.

[0043] Working principle of the invention:

[0044] The pipe or cable to be armored is located in the pipe hole of the cable outlet winch 1. Flat steel wire is input through the wire sleeve 19, then passes through the wire channel in the fixed seat 2, the hollow shaft 8, the torsion guide roller group 10, and the deflection guide roller group 5, and then extends towards the pipe or cable at the center of the cable outlet winch 1 via the grooved guide wheel 14 of the deflection guide roller group 5. It then spirally winds around the pipe or cable to form flat steel wire armor. During this process, the first toothed ring 6 and the second toothed ring 11 can be used to adjust the deflection and torsion angles of the flat steel wire, causing deformation before winding onto the pipe, and adjusting the angle of entry between the flat steel wire and the pipe according to the required angle. This ensures the flat steel wire naturally forms a spiral shape and winds around the pipe, guaranteeing the quality of the flat steel wire winding. This improves upon existing flat steel wire winding methods that easily result in uneven spacing of the flat steel wires, overlapping of some flat steel wires, high stress during winding leading to twisting and unevenness of the flat steel wires, and edge warping and deflection.

[0045] Specifically, when the first gear ring 6 rotates, it drives the connecting plate 4 and the deflection guide roller group 5 to rotate around the axis of the fixed seat 2 by a corresponding angle after being driven by the deflection wheel 3. This changes the deflection angle of the flat steel wire when it is output through the deflection guide roller group 5, and the cutting angle between the flat steel wire and the pipe can be adjusted as needed to ensure the flatness of the flat steel wire winding on the pipe surface. When the second gear ring 11 rotates, it drives the hollow shaft 8 and the deflection guide roller group 10 to rotate through the torsion wheel 9 meshing with the second gear ring 11. The torsion guide roller group 10 and the deflection guide roller group 5 work together to achieve pre-twisting deformation of the flat steel wire, change the angle of the flat steel wire, and thus allow the flat steel wire to naturally form a spiral shape and wind around the pipe, ensuring the quality of the flat steel wire winding.

[0046] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the scope of the claims.
