Description

Technical Field

[0001] The present invention belongs to the technical field of single-end yarn unwinding equipment, and particularly relates to a single-end yarn unwinding equipment for submarine optical cables. Background Art

[0002] In the production process of submarine optical cables, fibers such as aramid are sometimes used as raw materials for processing. Such fibers are used in rolls, so during use, the fiber ropes in rolls need to be unwound before use. In traditional production lines, a gantry unwinding rack is used for unwinding (as shown in Figure 10 ). After clamping the reel containing the fiber in the middle of the gantry unwinding rack, after pulling out the fiber rope end, the unwinding speed and unwinding tension are adjusted through a dancer wheel.

[0003] The adaptability of the traditional gantry unwinding rack to fibers such as aramid is relatively poor. First, such fibers have a certain elasticity. During unwinding, the unwinding speed and unwinding tension need to be controlled by changing the height of the dancer wheel. The elasticity of the fiber will cause the dancer wheel to fail to adjust in time, resulting in large fluctuations in speed and tension. Moreover, the tensile strength of the fiber is relatively low, and it is easy to break the fiber due to excessive tension under fluctuating conditions.

[0004] In the existing unwinding method, when changing the fiber, the gantry unwinding rack needs to be opened, and then clamped after replacement to complete the reel change work. The whole process is relatively cumbersome, and the number of reel changes per day is relatively large, reducing the production efficiency.

[0005] The existing unwinding method requires the use of a gantry unwinding rack. First, the price of this equipment is relatively high, and the installation and commissioning period is longer. Second, this equipment occupies a relatively large floor area and requires foundation reinforcement and circuit laying. Summary of the Invention

[0006] The purpose of the present invention is to provide a single-end yarn unwinding equipment for submarine optical cables to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A single-end yarn unwinding equipment for submarine optical cables, comprising:

[0009] A support module, a clamping module, and a damping module. One side of the upper end of the support module is provided with the clamping module for installing a fiber reel to facilitate the unwinding of the fiber rope on the fiber reel. The clamping module is installed with a fiber reel wound with a fiber rope. The other side of the upper end of the support module is provided with the damping module for adjusting the resistance when the fiber rope moves.

[0010] The bracket module includes a support column and a mounting support plate. The support column is connected to the mounting support plate. The clamping module is mounted on one side of the mounting support plate. A wire outlet hole is formed in the mounting support plate for the passing of the end of the fiber rope after passing through the damping module.

[0011] The clamping module includes a clamping cylinder, a tensioning member and a composite top cover. A hole is formed inside the clamping cylinder to facilitate the passing of the fiber rope. A plurality of groups of the tensioning members are further arranged inside the clamping cylinder for pressing the inner wall of the fiber reel sleeved on the clamping cylinder, which is conducive to the installation of the fiber reel. One end of the clamping cylinder is provided with the composite top cover. An arc surface is arranged at the outer end of the composite top cover to facilitate the movement of the fiber rope along the arc surface. For the smooth transition and to maximize the contact area between the fiber rope and the composite top cover, the situation of single-point friction is avoided, and the situation that the fiber rope is easily worn and broken by single-point friction is avoided.

[0012] The damping module includes a connecting rod, a mounting shell and a damping member. The other side of the mounting support plate is connected to the mounting shell through the connecting rod. The damping member is arranged inside the mounting shell, and the arranged damping member can be used to adjust the resistance when the fiber rope moves.

[0013] Preferably, a plurality of groups of the tensioning members are arranged, which can be at least three groups. The tensioning member includes a pressing hole, a pressing ball and a pressing spring. A pressing hole is formed at the outer end of the clamping cylinder. A pressing groove is further arranged inside the clamping cylinder. The pressing groove is connected to the pressing hole. The pressing ball is connected to the pressing spring inside the pressing groove. The pressing ball is arranged in a spherical structure to facilitate the rotation of the pressing ball. One end of the pressing ball extends to the outside of the pressing hole. The diameter of the pressing ball is larger than the inner diameter of the pressing hole to ensure that the pressing ball can be constrained in the pressing hole to prevent detachment. The pressing holes are arranged in three groups and the angle between two adjacent ones is 120 degrees, which is conducive to at least three support points of the tensioning members in the same plane contacting the inner wall of the clamping cylinder, and can better support the clamping cylinder. When the fiber reel with the fiber rope is sleeved on the clamping cylinder, the pressing ball can rotate to enable the fiber reel to be smoothly sleeved into the clamping module. At the same time, the pressing ball will receive the pressure brought by the fiber reel and press the pressing spring downward. After the pressing spring generates a force in the opposite direction, the pressing ball presses the inner wall of the fiber reel, and the pressing ball and the inner wall of the fiber reel support each other, so as to achieve the purpose of installing and fixing the fiber reel.

[0014] Preferably, the composite top cover is provided with a stainless steel fiber-PEEK gradient composite structure, which is a stainless steel fiber conductive layer vacuum-coated on the surface of a polyether ether ketone material to eliminate dead corners of static electricity accumulation. Specifically, PEEK has high temperature resistance. The glass transition temperature of PEEK is 143 °C, the melting point is 334 °C, and it can be used for a long time at 260 °C, with an instantaneous temperature resistance of up to 300 °C. The heat deflection temperature under load of its 30% glass fiber or carbon fiber reinforced model can reach 316 °C, which is suitable for high temperature environments; at the same time, it has high fatigue resistance and wear resistance and can replace metals for high-strength components; the conductive layer uses a 0.1 mm thick stainless steel fiber grid with surface composite. PEEK provides a rigid substrate and chemical corrosion resistance. The stainless steel fibers simultaneously undertake the triple functions of heat conduction, electricity conduction, and reinforcement, and achieve the "outer hard and inner tough" characteristic through fiber gradient distribution to meet the impact resistance requirements of the arc-shaped tooling; the PEEK particles mixed with fibers are molded into a flat plate at 320 °C and 50 MPa, the area to be formed into an arc is laser-heated to the glass transition temperature of PEEK, and a mechanical force is applied synchronously to bend it to the target curvature, and a stainless steel fiber conductive layer is vacuum-coated on the curved surface to eliminate dead corners of static electricity accumulation.

[0015] Preferably, the damping member includes a damping knob, a connecting shaft, a connecting rod, a resistance ring, and a resistance post. One side of the inner wall of the installation housing is rotatably connected with the connecting shaft, the damping knob is arranged on the outer side of the installation housing, the damping knob is connected with the connecting shaft, one side of the connecting shaft is connected with the connecting rod, the lower end of the connecting rod is connected with the resistance ring, a circular hole is opened inside the lower end of the resistance ring to facilitate the passing of the fiber cord. One side of the inner wall of the installation housing is also connected with the resistance post. The resistance post and the resistance ring are both provided in several groups and are alternately arranged with each other. Further, the resistance post and the resistance ring are alternately arranged at least three times. Specifically, there are at least three groups of resistance rings and at least four groups of resistance posts. When in use, the fiber cord is inserted from the through hole at one end, passes under the resistance post and then through the resistance ring, and finally passes out from the through hole at the other end of the damper. The connecting shaft is connected with the damping knob. When adjusting the damping knob, the connecting shaft rotates and drives the connecting rod at the same time, raising the resistance ring. The resistance ring drives the fiber cord passing through it to rise. At this time, the fiber cord is subjected to the force of the lower part of the resistance post and the lower end of the inner ring of the resistance ring, thereby increasing the friction between the fiber cord and the resistance post and the resistance ring. When the resistance knob is adjusted, as the angle of the connecting rod increases, the resistance received by the fiber cord also increases. By setting gears on the resistance knob, precise adjustment of different resistance requirements can be achieved. Further, the two through holes of the damper and the resistance post and the resistance ring are all made of the same material as the composite top cover.

[0016] Preferably, through holes are opened at both ends of the installation housing to facilitate the passing of the fiber cord.

[0017] Preferably, an installation through-hole matching with the clamping cylinder body is formed inside the installation support plate, which is beneficial to the installation of the clamping cylinder body. A bolt is installed at the bottom end of the installation support plate. One end of the bolt penetrates through the installation through-hole and fits with the clamping cylinder body. After installing the clamping cylinder body inside the installation through-hole of the installation support plate, by screwing the bolt, the end of the bolt abuts against the outer end of the clamping cylinder body, realizing its installation and fixation. Furthermore, the clamping cylinder body can be disassembled.

[0018] Preferably, the other end of the clamping cylinder body is provided with a cylinder bottom plate, and a hole is also formed inside the cylinder bottom plate, which is beneficial to the passage of the fiber rope.

[0019] Preferably, the support module further includes a support bottom rod and a stabilizing reinforcing rib. The lower end of the support column is connected to the support bottom rod, and the stabilizing reinforcing rib is connected between the support bottom rod and the support column, which improves the stability of the support and prevents it from deforming easily when the support module pays off the wire.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. Safety: The single-end yarn pay-off rack of this equipment is designed for passive wire pay-off, and the tension is provided by the damping module with a constant resistance, which is regarded as a basically constant-tension mode during the wire pay-off process;

[0022] 2. Convenience: This equipment is easy to operate during the process of replacing the bobbin. Just replace the new fiber rope bobbin before the end of the wire on the fiber rope bobbin passes through the wire pay-off hole, and then connect the end of the new fiber rope to the end of the old fiber rope to complete the material replacement. The operation is simple and risk-free;

[0023] 3. Cost performance: The structure of this pay-off rack is much simpler than that of the traditional gantry pay-off rack, with a low manufacturing cost. The floor area is smaller than that of the traditional gantry pay-off rack. There is no need to reinforce the foundation and lay circuits, and almost no debugging and installation are required, which is more convenient;

[0024] 4. Innovation: The composite top cover uses a new composite material. The stainless steel fibers form a three-dimensional conduction path in the PEEK matrix, and the surface resistivity is stable at the standard value, which can achieve static elimination; the fibers are arranged in the arc normal direction, with a high thermal conductivity. The arc structure optimizes the heat dissipation direction, further improving the thermal conductivity. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment:

[0040] Please refer to Figures 1-9 as shown, a single-head yarn wire-releasing device for submarine optical cables includes:

[0041] Bracket module 1, clamping module 2 and damping module 3. On one side of the upper end of the bracket module 1, a clamping module 2 is installed for installing the fiber reel 210, which facilitates the unwinding of the fiber rope 2101 on the fiber reel 210. A fiber reel 210 wound with the fiber rope 2101 is installed on the clamping module 2. On the other side of the upper end of the bracket module 1, a damping module 3 is installed for adjusting the resistance when the fiber rope 2101 moves;

[0042] The bracket module 1 includes a support column 11 and an installation support plate 12. The support column 11 is connected to the installation support plate 12. The clamping module 2 is installed on one side of the installation support plate 12. An outlet hole 13 is provided on the installation support plate 12 for the thread end of the fiber rope 2101 after passing through the damping module 3 to pass through;

[0043] The clamping module 2 includes a clamping cylinder 21, a tensioning member and a composite top cover 23. A hole is provided inside the clamping cylinder 21 to facilitate the passage of the fiber rope 2101. A plurality of groups of tensioning members are also provided inside the clamping cylinder 21 for pressing the inner wall of the fiber reel 210 sleeved on the clamping cylinder 21, which is beneficial to the installation of the fiber reel 210. One end of the clamping cylinder 21 is provided with a composite top cover 23, and the outer end of the composite top cover 23 is provided with an arc surface to facilitate the movement of the fiber rope 2101 along the arc surface. For the smooth transition and to maximize the contact area between the fiber rope 2101 and the composite top cover 23, to avoid the situation of single-point friction, and to avoid the situation that the fiber rope is easily worn and broken by single-point friction;

[0044] The damping module 3 includes a connecting rod 31, an installation housing 32 and a damping member. The other side of the installation support plate 12 is connected to the installation housing 32 through the connecting rod 31, and a damping member is provided inside the installation housing 32. The provided damping member can be used to adjust the resistance when the fiber rope 2101 moves.

[0045] Reference Figures 1-9As shown in the figure, the tensioning members are arranged in several groups, which can be at least three groups. The tensioning members include a pressing hole 211, a pressing ball 212, and a pressing spring 213. The outer end of the clamping cylinder 21 is provided with a pressing hole 211. A pressing groove is also provided inside the clamping cylinder 21. The pressing groove is connected to the pressing hole 211. A pressing ball 212 is connected to the inside of the pressing groove through a pressing spring 213. The pressing ball 212 is set as a spherical structure, which is beneficial to the rotation of the pressing ball 212. One end of the pressing ball 212 extends to the outside of the pressing hole 211. The diameter of the pressing ball 212 is larger than the inner diameter of the pressing hole 211 to ensure that the pressing ball 212 can be constrained in the pressing hole 211 to prevent it from detaching. The pressing holes 211 are set in three groups and the angle between two adjacent ones is 120 degrees, which is beneficial to at least three support points of the tensioning members contacting the inner wall of the clamping cylinder 21 in the same plane, and can better support the clamping cylinder 21. When the fiber reel 210 with the fiber rope 2101 is sleeved on the clamping cylinder 21, the pressing ball 212 can rotate, so that the fiber reel 210 can be smoothly sleeved into the clamping module 2. At the same time, the pressing ball 212 will receive the pressure brought by the fiber reel 210 and press the pressing spring 213 downward. After the pressing spring 213 generates a force in the opposite direction, the pressing ball 212 presses the inner wall of the fiber reel 210. The pressing ball 212 and the inner wall of the fiber reel 210 support each other, so as to achieve the purpose of installing and fixing the fiber reel 210.

[0046] Since friction will occur between the fiber rope and the clamping module during the continuous wire release process, a composite top cover is designed at the end of the clamping module. The edge of the composite top cover is arc-shaped. In order to achieve smooth transition and maximize the contact area between the fiber rope and the top cover, to avoid the situation of single-point friction, single-point friction is very likely to wear out the fiber rope. At the same time, the composite top cover needs to have good antistatic performance, because fiber ropes such as aramid are twisted by aramid fibers. Friction in the production route may cause static electricity to be generated. Static electricity will cause the aramid fiber rope to "explode strands", that is, the fibers repel each other after being charged, resulting in abnormal outer diameter, and even the separation of the fiber rope twisting structure, seriously affecting the product performance. And static electricity may cause production equipment failures. Friction will also generate more heat. Therefore, it must meet the requirements of antistatic, high temperature resistance, good heat conduction, wear resistance, and high surface finish.

[0047] Reference Figures 1-9As shown, for this reason, the composite top cover 23 is set as a stainless steel fiber-PEEK (polyether ether ketone) gradient composite structure. The stainless steel fiber-PEEK gradient composite structure is to electroplate a stainless steel fiber conductive layer on the surface of the polyether ether ketone material through magnetic field vacuum plating to eliminate the dead corners of static electricity accumulation. Specifically, PEEK has high temperature resistance. The glass transition temperature of PEEK is 143 °C, the melting point is 334 °C, it can be used for a long time at 260 °C, and the instantaneous temperature resistance reaches 300 °C. The heat deflection temperature under load of its 30% glass fiber or carbon fiber reinforced model can reach 316 °C, which is suitable for high temperature environments; at the same time, it has high fatigue resistance and wear resistance, and can replace metals for high-strength components; the conductive layer uses a surface composite stainless steel fiber grid with a thickness of 0.1 mm, and the resistivity ≤ 1×10 4 Ω·cm. PEEK provides a rigid substrate and chemical corrosion resistance. The stainless steel fibers simultaneously undertake the triple functions of heat conduction, electricity conduction, and reinforcement. The "hard outside and tough inside" characteristic is achieved through the fiber gradient distribution with a dense surface layer and a sparse core to meet the impact resistance requirements of the arc-shaped tooling; the PEEK particles mixed with fibers are molded into a flat plate at 320 °C and 50 MPa, and the area to be formed into an arc is laser heated to the glass transition temperature of PEEK, 143 °C, and a mechanical force is applied synchronously to bend it to the target curvature R≥50 mm. A stainless steel fiber conductive layer is electroplated on the bending surface to eliminate the dead corners of static electricity accumulation.

[0048] Furthermore, through magnetic field assistance, the stainless steel fibers can be arranged along the arc normal direction (the magnetic field strength can be limited to ≥0.5 Tesla (T)). The molding temperature affects the crystallinity of PEEK, and the magnetic field strength determines the fiber orientation.

[0049] · Matrix material: Modified PEEK resin (the glass fiber reinforcement ratio is limited, 30% glass fiber reinforced PEEK);

[0050] · Conductive layer structure: Surface composite stainless steel fiber grid with a thickness of 0.1 mm (resistivity ≤ 1×10 4 Ω·cm);

[0051] · Gradient distribution characteristics: The stainless steel fibers are arranged in the arc normal direction, and the surface density > core density (25% volume ratio on the surface, 15% volume ratio in the core);

[0052] · Functional parameters: Surface resistivity 10 6 -10 8 Ω (ASTM D257 standard), and the normal thermal conductivity coefficient ≥ 12 W / m·K.

[0053] The composite top cover 23 uses a new material composite. The stainless steel fibers form a three-dimensional conduction path in the PEEK matrix, and the surface resistivity is stabilized at 10 6 -10 8Ω (ASTM D257 standard), can achieve static elimination; the fibers are oriented along the arc normal direction, with a thermal conductivity of 12 - 15 W / m·K (8 times higher than that of pure PEEK), and the arc structure optimizes the heat dissipation direction (heat radiates outward along the curved surface), further enhancing the thermal conductivity.

[0054] Cost performance: This pay-off rack structure is much simpler than the traditional gantry pay-off rack, with low manufacturing costs. Even the raw material cost of the composite top cover structure is only about 600 yuan / kg, and the processing cost is about 300 yuan. The floor area is much lower than that of the traditional gantry pay-off rack, without the need for foundation reinforcement and circuit laying, and almost no commissioning and installation are required.

[0055] Innovation: The composite top cover uses a new material composite, where stainless steel fibers form a three-dimensional conduction path in the PEEK matrix, and the surface resistivity is stable at 10 6 -10 8 Ω (ASTM D257 standard), can achieve static elimination; the fibers are oriented along the arc normal direction, with a thermal conductivity of 12 - 15 W / m·K (8 times higher than that of pure PEEK), and the arc structure optimizes the heat dissipation direction (heat radiates outward along the curved surface), further enhancing the thermal conductivity.

[0056] Reference Figures 1-9As shown in the figure, the damping member includes a damping knob 33, a connecting shaft 34, a connecting rod 35, a resistance ring 36 and a resistance column 37. One side of the inner wall of the mounting housing 32 is rotatably connected to the connecting shaft 34. A damping knob 33 is provided on the outside of the mounting housing 32. The damping knob 33 is connected to the connecting shaft 34. One side of the connecting shaft 34 is connected to a connecting rod 35. The lower end of the connecting rod 35 is connected to a resistance ring 36. A circular hole is provided inside the lower end of the resistance ring 36 to facilitate the passage of the fiber rope 2101. One side of the inner wall of the mounting housing 32 is also connected to a resistance column 37. Both the resistance column 37 and the resistance ring 36 are provided in several groups and are alternately arranged with each other. Further, the resistance column 37 and the resistance ring 36 are alternately arranged at least three times. Specifically, there are at least three groups of resistance rings 36 and at least four groups of resistance columns 37. When in use, after the fiber rope 2101 is inserted from the through-hole at one end, it passes under the resistance column 37 and then through the resistance ring 36, and finally passes out from the through-hole at the other end of the damper. The connecting shaft 34 is connected to the damping knob 33. When adjusting the damping knob 33, the connecting shaft 34 rotates and drives the connecting rod 35 at the same time, raising the resistance ring 36. The resistance ring 36 drives the fiber rope 2101 passing through it to rise. At this time, the fiber rope 2101 is subjected to the force of the lower part of the resistance column 37 and the lower end of the inner ring of the resistance ring 36, thereby increasing the friction between the fiber rope 2101 and the resistance column 37 and the resistance ring 36. When the resistance knob is adjusted, as the angle of the connecting rod 35 increases, the resistance received by the fiber rope 2101 also increases. By setting gears on the resistance knob, precise adjustment of different resistance requirements can be achieved. Further, the two through-holes of the damper and the resistance column 37 and the resistance ring 36 are all made of the same material as the composite top cover 23.

[0057] Further, gears can be set on the outside of the damping knob, that is, the linear correspondence between the damping knob gears and the angles of the connecting rods (it can be 5 degrees of rotation per gear, and the resistance increases by 20%).

[0058] Reference Figures 1-9 As shown in the figure, through-holes are provided at both ends of the mounting housing 32 to facilitate the passage of the fiber rope 2101.

[0059] Reference Figures 1-9 As shown in the figure, an installation through-hole matching the clamping cylinder 21 is provided inside the installation support plate 12, which is beneficial to the installation of the clamping cylinder 21. Bolts are installed at the bottom end of the installation support plate 12. One end of the bolt passes through the installation through-hole and fits against the clamping cylinder 21. After the clamping cylinder 21 is installed inside the installation through-hole of the installation support plate 12, by turning the bolt, the end of the bolt abuts against the outer end of the clamping cylinder 21 to achieve its installation and fixation. Furthermore, the clamping cylinder 21 can be disassembled. For fiber ropes with larger or smaller diameters, other corresponding-sized clamping cylinders 21 can be selected for use.

[0060] ReferenceFigure 3 As shown, a cylinder base plate 22 is provided at the other end of the clamping cylinder body 21, and a duct is also provided inside the cylinder base plate 22, which is beneficial for the fiber rope 2101 to pass through.

[0061] Reference Figures 1-2 As shown, the support module 1 further includes a support bottom rod and a stabilizing reinforcing rib 14. The lower end of the support column 11 is connected to the support bottom rod, and a stabilizing reinforcing rib 14 is connected between the support bottom rod and the support column 11 to improve the stability of the support and prevent it from deforming easily when the support module 1 is under the force of wire release.

[0062] During use, by selecting the clamping module 2 that matches the size of the currently used fiber reel 210, after installing the clamping module 2 onto the support module 1, the fiber reel 210 is sleeved onto the clamping cylinder body 21. At this time, the outermost rope end of the fiber rope 2101 is released, and the wire is released along the Figure 9 path. First, it passes through the composite top cover 23, then through the central duct of the clamping cylinder body 21. After exiting the duct, it enters the duct of the damping module 3. After alternately passing under the resistance column 37 and inside the resistance ring 36 of the damping module 3, it exits the damping module 3, and then the rope end exits through the wire outlet hole 13 of the support module 1 and is released along the production line direction. At this time, the required resistance is set by adjusting the gear of the resistance knob 33 of the damping module 3.
