Description

Technical Field

[0001] This invention relates to the field of carbon fiber rope manufacturing technology, and in particular to a large-diameter carbon fiber rope braiding device and its usage method. Background Technology

[0002] Carbon fiber rope is a lightweight, high-strength rope made by weaving or twisting carbon fiber bundles. It combines the excellent properties of carbon fiber materials with the flexibility of rope, and has the advantages of high strength (more than 5 times that of steel), lightweight (density is 1 / 4 that of steel), corrosion resistance, fatigue resistance, low coefficient of thermal expansion (good dimensional stability in high or low temperature environments), electrical conductivity, and good flexibility. It is widely used in aerospace, marine engineering, sports equipment and other fields.

[0003] Carbon fiber ropes produced using conventional methods have certain drawbacks, such as loose structure and small diameter, making them unsuitable for traction of large and thick soft felts. Their performance cannot be guaranteed, especially in high-temperature environments, indicating that the strength and stability of carbon fiber ropes need further improvement. Furthermore, the current low production efficiency of carbon fiber ropes limits their application range. Summary of the Invention

[0004] This invention provides a large-diameter carbon fiber rope braiding device and its usage method, overcoming the defects of existing carbon fiber ropes being loose in structure and small in diameter. The large-diameter, high-strength carbon fiber rope produced is not only suitable for pulling large and thick soft felts, but its performance is also unaffected when used in high-temperature environments. It effectively solves the problem of the current limited application range of carbon fiber ropes, laying the foundation for the application of carbon fiber ropes in a wider range of fields.

[0005] To achieve the above objectives, the present invention employs the following technical solution: A large-diameter carbon fiber rope braiding device includes a winding assembly, a slide rail, a rope separator, a rope twisting assembly, and a rope take-up assembly. The winding assembly comprises a winding motor, a large gear, small gears, and a winding shaft. The motor shaft of the winding motor is connected to the large gear. Multiple small gears are arranged around the large gear, meshing with it. The winding shaft is coaxial with and rotates with the small gears. The winding shaft is hollow and has a spiral groove on its inner wall. A rope hook is provided at the outer end of the winding shaft. The winding assembly and the rope twisting assembly are connected... The system includes a slide rail along which the rope distributor can move. The rope distributor has rope grooves, the number of which is the same as the number of upper winding shafts. The rope twisting assembly consists of a rope twisting motor and a rope twisting shaft. The rope twisting shaft is the power output shaft of the rope twisting motor, and its axis is aligned with the axis of the large gear. The rope twisting shaft is hollow and has helical grooves on its inner wall, with the direction of rotation of the helical grooves consistent with the direction of rope twisting. The rope take-up assembly consists of a take-up shaft and a take-up motor. The take-up shaft is perpendicular to the rope twisting shaft and is the power output shaft of the take-up motor.

[0006] A large-diameter carbon fiber rope braiding device further includes a tensioning bracket and a rope twisting frame; the tensioning component is disposed on the tensioning bracket, and the rope twisting component and the rope winding component are disposed on the rope twisting frame; two slide rails are arranged in parallel between the tensioning bracket and the rope twisting frame, and the two ends of the slide rails are detachably fixedly connected to the tensioning bracket and the rope twisting frame respectively through supports.

[0007] The upper winding motor in the upper winding assembly is connected to the upper winding bracket via a motor bracket. A mounting plate is provided on the inner side of the large gear, and the mounting plate is connected to the motor bracket. The mounting plate has an opening for the motor shaft of the upper winding motor to pass through. One end of the upper winding shaft is connected to the motor bracket via a bearing seat, and the other end of the upper winding shaft passes through the small gear and is provided with a rope hook at the passing end. The upper winding shaft and the small gear are connected by a key.

[0008] The motor mentioned is a variable frequency motor.

[0009] The rope separator consists of a frustum, connecting rods, and sliding sleeves. The axis of the frustum is on the same straight line as the axis of the large gear. The large end of the frustum is close to the large gear. Multiple rope grooves are evenly opened around the periphery of the frustum. Connecting rods are provided on both sides of the frustum and connected to the corresponding sliding sleeves. The sliding sleeves are slidably connected to the slide rails.

[0010] The slide rail is equipped with proximity switches at one end near the winding assembly and at the other end near the twisting assembly. The proximity switches are interlocked with the twisting motor and the take-up motor through the control system.

[0011] The rope-twisting motor is a hollow shaft type orthogonal shaft geared motor.

[0012] The two ends of the rope take-up shaft are connected to the rope twisting frame through bearing seats, and a rope take-up hook is provided at one end of the rope take-up shaft; the rope take-up motor is a right-angle shaft type geared motor.

[0013] A method for using a large-diameter carbon fiber rope braiding device includes the following steps: 1) 4 to 8 strands of fine carbon fiber rope are drawn out from the corresponding winding shaft, pass through the corresponding upper winding shaft, go around the corresponding hanging rope hook, pass through the corresponding rope groove on the rope separator, and then pass out from the twisting shaft and are fixed on the rope take-up hook of the take-up shaft. 2) Start the tensioning motor, twisting motor, and take-up motor; the tensioning motor drives the large gear to rotate, which in turn drives the small gears to rotate; the tensioning shaft rotates synchronously with the small gears, and the spiral groove of the tensioning shaft tensions the strands of fine carbon fiber rope; after tensioning, the multiple strands of fine carbon fiber rope are automatically twisted together by the rope separator to form a thick carbon fiber rope; at the same time, the twisting motor drives the twisting shaft to rotate, and the take-up motor drives the take-up shaft to rotate; the thick carbon fiber rope moves forward under the guidance of the spiral groove on the twisting shaft and is wound on the take-up shaft; 3) The force generated during the twisting process of the fine carbon fiber rope causes the rope separator to slowly move along the slide rail towards the twisting assembly. When the rope separator moves to the limit position near the winding assembly, the corresponding proximity switch is triggered. The control system controls the twisting motor to increase its speed, causing the rope separator to move in the opposite direction. When the rope separator moves to the limit position near the twisting assembly, the corresponding proximity switch is triggered. The control system controls the winding motor to increase its speed. Through the two proximity switches, the twisting and winding actions are balanced, thereby ensuring the tightness and uniformity of the coarse carbon fiber rope. 4) After the coarse carbon fiber rope is woven, tie a knot at the end of each strand of fine carbon fiber rope to prevent the coarse carbon fiber rope from loosening. Remove the woven coarse carbon fiber rope from the take-up shaft to complete the production of the large-diameter coarse carbon fiber rope.

[0014] Each fine carbon fiber rope consists of at least 3 carbon fiber bundles, and each carbon fiber bundle is made of 1,000 to 3,000 carbon fiber filaments twisted together; the diameter of the carbon fiber filaments is 5 to 10 μm, the tensile strength is 3.5 to 7 GPa, and the elastic modulus of the carbon fiber filaments is 200 to 600 GPa; the coarse carbon fiber rope formed after twisting has a diameter of 10 to 60 mm and a tensile strength of 3 to 6 GPa.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1) By twisting 4 to 8 strands of carbon fiber rope together to form a large-diameter, high-strength carbon fiber rope, the defects of the existing carbon fiber rope structure being loose and having a small diameter are overcome. The large-diameter, high-strength carbon fiber rope produced is not only suitable for pulling large and thick soft felt, but its performance will not be affected when used in high-temperature environments. 2) The large-diameter carbon fiber rope braiding device described in this invention can effectively improve the strength and stability of carbon fiber ropes, meeting the application requirements of different application scenarios. 3) The large-diameter carbon fiber rope braiding device of the present invention adopts a process of twisting and tightening first, and then twisting the rope, and can realize automated control, which improves the production efficiency and quality stability of carbon fiber rope and reduces production costs. 4) It enables the large-scale production of large-diameter, high-strength carbon fiber ropes, which is conducive to expanding the application range of carbon fiber ropes and laying the foundation for the application of carbon fiber ropes in a wider range of fields.

[0022] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings: like Figures 1-5 As shown, the large-diameter carbon fiber rope braiding device of the present invention includes a winding assembly, a slide rail 8, a rope separator 7, a rope twisting assembly, and a rope take-up assembly. The winding assembly consists of a winding motor 2, a large gear 3, a small gear 4, and a winding shaft 5. The motor shaft of the winding motor 2 is connected to the large gear 3 for transmission. Multiple small gears 4 are arranged around the large gear 3, and the small gears 4 mesh with the large gear 3 for transmission. The winding shaft 5 is coaxially arranged with the small gears 4 and rotates with the small gears 4. The winding shaft 5 is a hollow shaft with a spiral groove on its inner wall, and a rope hook is provided at the outer end of the winding shaft 5. A slide rail is provided between the winding assembly and the rope twisting assembly. 8. The rope separator 7 can move along the slide rail 8. The rope separator 7 is provided with rope grooves, and the number of rope grooves is the same as the number of upper winding shafts 5. The rope twisting assembly consists of a rope twisting motor 12 and a rope twisting shaft 13. The rope twisting shaft 13 is the power output shaft of the rope twisting motor 12. The axis of the rope twisting shaft 13 is on the same straight line as the axis of the large gear 3. The rope twisting shaft 13 is a hollow shaft and has a spiral groove on its inner wall. The spiral groove rotates in the same direction as the rope twisting direction. The rope taking-up assembly consists of a rope taking-up shaft 14 and a rope taking-up motor 15. The rope taking-up shaft 14 is set perpendicular to the rope twisting shaft 13 and is the power output shaft of the rope taking-up motor 15.

[0023] The large-diameter carbon fiber rope braiding device of the present invention further includes a winding support 1 and a rope twisting frame 11; the winding assembly is disposed on the winding support 1, and the rope twisting assembly and the rope winding assembly are disposed on the rope twisting frame 11; two slide rails 8 are arranged in parallel between the winding support 1 and the rope twisting frame 11, and the two ends of the slide rails 8 are detachably fixedly connected to the winding support 1 and the rope twisting frame 11 through supports respectively.

[0024] like Figure 2As shown, the upper winding motor 2 in the upper winding assembly is connected to the upper winding bracket 1 through the motor bracket. The inner side of the large gear 3 is provided with a mounting plate, which is connected to the motor bracket. The mounting plate has an opening for the motor shaft of the upper winding motor 2 to pass through. One end of the upper winding shaft 5 is connected to the motor bracket through a bearing seat. The other end of the upper winding shaft 5 passes through the small gear 4 and is provided with a rope hook at the passing end. The upper winding shaft 5 and the small gear 4 are connected by a key.

[0025] The upper motor 2 is a variable frequency motor.

[0026] like Figure 4 As shown, the rope separator 7 consists of a frustum, connecting rods, and sliding sleeves. The axis of the frustum is on the same straight line as the axis of the large gear 3. The large end of the frustum is close to the large gear 3. Multiple rope grooves are evenly opened around the periphery of the frustum. Connecting rods are provided on both sides of the frustum and connected to the corresponding sliding sleeves. The sliding sleeves are slidably connected to the slide rail 8.

[0027] The slide rail 8 is equipped with proximity switches 9 at one end near the tensioning assembly and at the other end near the twisting assembly. The proximity switches 9 are interlocked with the tensioning motor 2, the twisting motor 12 and the take-up motor 15 through the control system.

[0028] The rope twisting motor 12 is a hollow shaft type orthogonal shaft geared motor.

[0029] The two ends of the rope take-up shaft 14 are connected to the rope twisting frame 11 through bearing seats, and a rope take-up hook is provided at one end of the rope take-up shaft 14; the rope take-up motor 15 is a right-angle shaft type geared motor.

[0030] The method of using the large-diameter carbon fiber rope braiding device of the present invention includes the following steps: 1) 4 to 8 strands of fine carbon fiber rope 6 are drawn out from the corresponding winding shaft, pass through the corresponding upper winding shaft 5, go around the corresponding hanging rope hook, pass through the corresponding rope groove on the rope separator 7, and then pass out from the twisting rope shaft 13 and are fixed on the rope take-up hook of the take-up shaft 14. 2) Start the tensioning motor 2, the twisting motor 12, and the take-up motor 15; the tensioning motor 2 drives the large gear 3 to rotate, which in turn drives each small gear 4 to rotate; the tensioning shaft 5 rotates synchronously with the small gears 4, and the spiral groove of the tensioning shaft 5 is used to tension each strand of fine carbon fiber rope 6; after tensioning, the multiple strands of fine carbon fiber rope 6 are automatically twisted together after passing through the rope separator 7 to form a thick carbon fiber rope 10; at the same time, the twisting motor 12 drives the twisting shaft 13 to rotate, and the take-up motor 15 drives the take-up shaft 14 to rotate; the thick carbon fiber rope 10 moves forward under the guidance of the spiral groove on the twisting shaft 13 and is wound around the take-up shaft 14; 3) The force generated during the twisting process of the fine carbon fiber rope 6 causes the rope separator 7 to slowly move along the slide rail 8 towards the twisting assembly. When the rope separator 7 moves to the limit position near the twisting assembly, the corresponding proximity switch 9 is triggered. The control system controls the twisting motor 12 to increase its speed, causing the rope separator 7 to move in the opposite direction. When the rope separator 7 moves to the limit position near the twisting assembly, the corresponding proximity switch 9 is triggered. The control system controls the winding motor 15 to increase its speed. Through the two proximity switches 9, the twisting and winding actions are balanced, thereby ensuring the tightness and uniformity of the coarse carbon fiber rope 10. 4) After the coarse carbon fiber rope 10 is woven, tie a knot at the end of the twisted end of each strand of fine carbon fiber rope 6 to prevent the coarse carbon fiber rope 10 from loosening. Remove the woven coarse carbon fiber rope 10 from the rope take-up shaft 14 to complete the production of the large diameter coarse carbon fiber rope.

[0031] Each fine carbon fiber rope 6 consists of at least 3 carbon fiber bundles, and each carbon fiber bundle is made of 1,000 to 3,000 carbon fiber filaments twisted together; the diameter of the carbon fiber filaments is 5 to 10 μm, the tensile strength is 3.5 to 7 GPa, and the elastic modulus of the carbon fiber filaments is 200 to 600 GPa; the coarse carbon fiber rope 10 formed after twisting has a diameter of 10 to 60 mm and a tensile strength of 3 to 6 GPa.

[0032] The large-diameter carbon fiber rope braiding device described in this invention is a complete set of devices designed to achieve automatic braiding of carbon fiber ropes, such as... Figure 1 As shown, the main components include a rope twisting frame 11, a rope twisting motor 12, a rope twisting shaft 13, a rope separator 7, a slide rail 8, a winding shaft 5, a large gear 3, a small gear 4, a winding motor 2, a winding support 1, a take-up shaft 14, a take-up motor 15, a proximity switch 9, and a control system. Its working principle is as follows: 4-8 strands of fine carbon fiber rope 6 are selected, each strand being made of multiple carbon fiber filaments twisted together; the pre-treated strands of fine carbon fiber rope 6 are arranged in a petal-like pattern, and the strands are twisted using a rotary twisting method to form a wound fine carbon fiber rope; the wound strands of fine carbon fiber rope 6 are then twisted using a twisting mechanism to finally form a large-diameter carbon fiber rope (referred to as a coarse carbon fiber rope). The woven large-diameter carbon fiber rope is then tensioned and coiled to become the finished product.

[0033] The tensioning assembly described in this invention is used to tension 4 to 8 strands of fine carbon fiber rope 6. When the fine carbon fiber rope 6 passes through the rotating tensioning shaft 5, it is continuously tensioned under the action of the spiral groove. Then, the multiple strands of fine carbon fiber rope 6 are twisted together after the rope separator 7, and move forward under the guidance and driving action of the spiral groove in the rotating rope twisting shaft 13, and finally wrapped around the rope take-up shaft 14.

[0034] The length of the slide rail 8 described in this invention is preferably 1 to 3 meters, and two slide rails 8 are preferably provided. Proximity switches 9 are respectively installed at both ends of one slide rail 8. The signal output terminals of the proximity switches 9 are connected to the control system, which is also connected to the control terminals of the twisting motor 12 and the take-up motor 15. Triggering one of the proximity switches 9 adjusts the speed of the corresponding motor, causing the rope separator 7 to continuously slide back and forth between the winding assembly and the twisting assembly during the rope braiding process.

[0035] Compared with conventional carbon fiber rope braiding equipment, the advantages of this invention are as follows: 1) The special design of the winding structure, with the winding motor driving the large gear to rotate, and the large gear driving multiple (preferably 4 to 8) small gears to rotate synchronously, thereby achieving uniform winding of the fine carbon fiber rope and ensuring the uniformity of the large-diameter carbon fiber rope structure; 2) The rope separator adopts a frustum structure, with multiple concave rope grooves (preferably 4 to 8) on the outer surface of the frustum. The fine carbon fiber rope is placed in the rope grooves, which can effectively prevent the fine carbon fiber rope from tangling together before stranding during the winding process, thereby further ensuring the uniformity of the large-diameter carbon fiber rope structure and the smooth stranding process; 3) The twisting process adopts automatic control. During the winding and twisting process of the fine carbon fiber rope, the rope separator slides along the slide rail through the interlocking control of the proximity switch and each motor, ensuring uniform winding and preventing the coarse carbon fiber rope from becoming loose or too tight in some areas.

[0036] The large-diameter carbon fiber rope braiding device described in this invention can produce large-diameter carbon fiber ropes with a large diameter and a compact and uniform structure, solving the problems of loose structure and small diameter that are common in existing carbon fiber ropes. The large-diameter carbon fiber rope produced by this invention has high strength and good stability, and is not easy to break after long-term use. At the same time, it improves the production efficiency of carbon fiber ropes and the degree of automation of the equipment.

[0037] Currently available carbon fiber ropes are not suitable for pulling large and thick soft felts, especially when used in high-temperature environments where their performance deteriorates and oxidation or breakage may occur. However, the carbon fiber rope produced using the large-diameter carbon fiber rope braiding device described in this invention has high strength, can pull large and thick soft felts, and can be used in continuous carbonization furnaces and graphitization furnaces without oxidation or breakage even after prolonged use (more than one month).

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
