Description

Technical Field

[0001] This application relates to the field of umbilical cable winding technology, specifically to an umbilical cable winding system. Background Technology

[0002] An umbilical cable is a product composed of a power cable or signal cable, an optical cable (single-mode or multi-mode optical cable), and hydraulic or chemical conduits (steel pipes or hoses). The main functions of an umbilical cable include providing power to the subsea production system, providing hydraulic channels for the control of the subsea production system, providing chemical pipelines required for oil and gas field development, and transmitting control signals from the top module and sensor data from the subsea production system. It is mainly used for deep-water oil and gas exploration and development, such as the transmission of power, signals, and data, and the transportation of chemicals and liquids between the seabed and the subsea production system.

[0003] In existing technologies, umbilical cables are wound onto a drum to facilitate their transport. Currently, most umbilical cables are wound manually in conjunction with an electric drum, but this method is inefficient and labor-intensive, leaving room for improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an umbilical cable winding system that can automatically wind umbilical cables during winding, avoiding the need for manual winding with an electric drum, reducing the workload of workers, and improving work efficiency. This system solves the problem in existing technologies where umbilical cables are wound onto drums for easy transport, and currently, most winding is done manually with an electric drum, which results in low winding efficiency and high labor costs.

[0005] To achieve the above objectives, this application provides the following technical solution: an umbilical cable winding system, comprising a base plate, a base fixedly connected to the upper surface of the base plate, a rotating shaft rotatably connected inside the base, a winding drum slidably sleeved on the outer circumferential surface of the rotating shaft, a first positioning ring fixedly sleeved on the outer circumferential surface of the rotating shaft, a second positioning ring threadedly connected to the outer circumferential surface of the rotating shaft, the winding drum located between the first and second positioning rings, two side plates fixedly connected to the upper surface of the base plate, a lead screw rotatably connected inside the two side plates, a threaded tube threadedly connected to the outer circumferential surface of the lead screw, a first fixing plate fixedly connected to the outer circumferential surface of the threaded tube, and a cable laying drum fixedly connected inside the first fixing plate.

[0006] The above solution addresses the issue that, in existing technologies, umbilical cables are wound onto a drum for easy transport. Currently, this is mostly done manually with the help of an electric drum, which is inefficient and labor-intensive. By rotating a lead screw, the threaded tube moves, causing the first fixed plate to move the cable-laying drum back and forth, thus automatically laying the umbilical cable while it is being wound. This eliminates the need for manual winding with the electric drum, reducing the workload for workers and improving efficiency.

[0007] Furthermore, a bracket is fixedly connected to the upper surface of the base plate, a reduction gearbox is provided at the top of the bracket, a rotary motor is provided at the top of the reduction gearbox, the output end of the rotary motor is connected to the input end of the reduction gearbox, and the output end of the reduction gearbox is fixedly connected to one end of the rotating shaft.

[0008] The above scheme uses a rotary motor to provide power, a gearbox to reduce the speed and increase the torque, ensuring that the shaft can rotate smoothly and slowly, thereby controlling the winding speed of the umbilical cable and avoiding uneven winding or damage caused by excessive speed. The bracket serves as a support structure to ensure the stable installation of the gearbox and rotary motor.

[0009] Furthermore, a limiting plate is fixedly connected to the inner wall of the winding drum, and a limiting groove is formed inside the rotating shaft. The limiting plate is slidably connected to the rotating shaft through the limiting groove.

[0010] Through the above scheme, the limiting plate and limiting groove can restrict the winding drum, prevent the winding drum from rotating relative to the rotating shaft, and ensure that the winding drum always rotates and winds with the rotating shaft, thereby improving the stability of the winding operation.

[0011] Furthermore, a crossbar is fixedly connected inside the two side plates, and a collar is slidably sleeved on the outer circumferential surface of the crossbar. A second fixing plate is fixedly connected to the outer circumferential surface of the collar, and the top end of the second fixing plate is fixedly connected to the outer circumferential surface of the cable tray.

[0012] The above scheme restricts the threaded tube, preventing it from rotating with the lead screw, thus ensuring the cable drum always moves laterally. It also supports the cable drum, improving its stability.

[0013] Furthermore, the cable tray has a hollow structure, and both ends of the cable tray have arc-shaped structures.

[0014] The above-mentioned design allows the umbilical cable to pass through the inside of the cable tray, thereby guiding the cable routing. The arc-shaped design at both ends helps to guide the umbilical cable to enter and leave the cable tray smoothly, reducing friction and wear, and improving winding efficiency and quality.

[0015] Furthermore, a U-shaped positioning component is slidably inserted into the inside of the winding drum, and two nuts are threadedly connected to the outer circumference of the U-shaped positioning component.

[0016] The above method allows for tightening the nut to fix one end of the umbilical cable inside the U-shaped positioning component, positioning the umbilical cable at the initial stage of the winding operation. This ensures that one end of the umbilical cable can be fixed on the winding drum, facilitating subsequent winding operations and improving winding efficiency.

[0017] Furthermore, a servo motor is fixedly connected to the outer surface of one of the side plates, and the output end of the servo motor is fixedly connected to one end of the lead screw.

[0018] Through the above scheme, the servo motor can provide power to the lead screw, drive the lead screw to rotate, and thus make the cable laying drum move back and forth to perform cable laying operations.

[0019] Furthermore, two limiting rings are fixedly sleeved on the outer circumferential surface of the rotating shaft, and the side of the limiting rings near the base contacts the outer surface of the base respectively.

[0020] The above method restricts the rotation shaft, preventing it from sliding and shifting, and improving the stability of its movement.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This umbilical cable winding system uses a screw to rotate, which moves a threaded tube and causes a first fixed plate to move a cable-laying drum back and forth. This automatically lays the umbilical cable during winding, eliminating the need for manual operation with an electric drum, reducing the workload for workers, and improving efficiency. The system also features a first positioning ring fixed to the shaft and a second positioning ring threaded to the shaft, facilitating the installation and removal of the winding drum and providing convenience for operators, further improving the efficiency of umbilical cable winding.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 4 An umbilical cable winding system in this embodiment includes a base plate 1. A base 22 is fixedly connected to the upper surface of the base plate 1. A rotating shaft 2 is rotatably connected inside the base 22. A winding drum 3 is slidably sleeved on the outer circumferential surface of the rotating shaft 2. A first positioning ring 4 is fixedly sleeved on the outer circumferential surface of the rotating shaft 2. A second positioning ring 5 is threadedly connected to the outer circumferential surface of the rotating shaft 2. The winding drum 3 is located between the first positioning ring 4 and the second positioning ring 5. Two side plates 6 are fixedly connected to the upper surface of the base plate 1. A lead screw 7 is rotatably connected inside the two side plates 6. A threaded tube 8 is threadedly connected to the outer circumferential surface of the lead screw 7. A first fixing plate 9 is fixedly connected to the outer circumferential surface of the threaded tube 8. A cable laying drum 23 is fixedly connected inside the first fixing plate 9.

[0032] Please see Figure 1 , Figure 2 and Figure 3 A bracket 10 is fixedly connected to the upper surface of the base plate 1. A reduction gearbox 11 is provided at the top of the bracket 10. A rotary motor 12 is provided at the top of the reduction gearbox 11. The output end of the rotary motor 12 is connected to the input end of the reduction gearbox 11. The output end of the reduction gearbox 11 is fixedly connected to one end of the rotating shaft 2. The rotary motor 12 provides power, and the speed is reduced and the torque is increased through the reduction gearbox 11 to ensure that the rotating shaft 2 can rotate smoothly and slowly, thereby controlling the winding speed of the umbilical cable and avoiding uneven winding or damage caused by excessive speed. The bracket 10 serves as a support structure to ensure the stable installation of the reduction gearbox 11 and the rotary motor 12.

[0033] Please see Figure 1 and Figure 4A limiting plate 13 is fixedly connected to the inner wall of the winding drum 3, and a limiting groove 14 is opened inside the rotating shaft 2. The limiting plate 13 is slidably connected to the rotating shaft 2 through the limiting groove 14. The limiting plate 13 and the limiting groove 14 can restrict the winding drum 3, prevent the winding drum 3 from rotating relative to the rotating shaft 2, and make the winding drum 3 always follow the rotating shaft 2 to rotate and wind, thereby improving the stability of the winding operation.

[0034] Please see Figure 1 , Figure 2 and Figure 5 A crossbar 15 is fixedly connected inside the two side plates 6. A collar 16 is slidably sleeved on the outer circumference of the crossbar 15. A second fixing plate 17 is fixedly connected to the outer circumference of the collar 16. The top of the second fixing plate 17 is fixedly connected to the outer circumference of the cable drum 23, which restricts the threaded tube 8 and prevents the threaded tube 8 from rotating with the screw 7, so that the cable drum 23 always moves laterally. At the same time, it also supports the cable drum 23 and improves the stability of the movement of the cable drum 23.

[0035] Please see Figure 1 and Figure 5 The cable tray 23 has a hollow structure with arc-shaped ends. The hollow structure of the cable tray 23 allows the umbilical cable to pass through the inside of the cable tray 23, thereby guiding the cable. The arc-shaped design at both ends helps to guide the umbilical cable to enter and leave the cable tray 23 smoothly, reducing friction and wear, and improving winding efficiency and quality.

[0036] Please see Figure 2 and Figure 4 The inside of the winding drum 3 is slidably inserted with a U-shaped positioning component 18. The outer circumferential surface of the U-shaped positioning component 18 is threaded with two nuts 19. The nuts 19 can be tightened to fix one end of the umbilical cable inside the U-shaped positioning component 18. The umbilical cable is positioned at the beginning of the winding operation, so that one end of the umbilical cable can be fixed on the winding drum 3, which facilitates the subsequent winding operation and improves the efficiency of the winding operation.

[0037] Please see Figure 1 , Figure 2 and Figure 3 One of the side plates 6 has a servo motor 20 fixedly connected to its outer surface. The output end of the servo motor 20 is fixedly connected to one end of the lead screw 7. The servo motor 20 can provide power to the lead screw 7, drive the lead screw 7 to rotate, and thus make the cable drum 23 reciprocate to perform cable laying operation.

[0038] Please see Figure 2 and Figure 3Two limiting rings 21 are fixedly sleeved on the outer circumferential surface of the rotating shaft 2. The side of the limiting ring 21 closest to the base 22 contacts the outer surface of the base 22 to restrict the rotating shaft 2, prevent the rotating shaft 2 from sliding and deviating, and improve the stability of the rotating shaft 2's movement.

[0039] In this embodiment, an umbilical cable winding system uses a screw 7 to rotate, which drives the threaded tube 8 to move. This causes the first fixed plate 9 to move the cable winding drum 23 back and forth, thereby automatically winding the umbilical cable. This avoids the need for manual operation with an electric drum, reducing the workload of workers and improving work efficiency. By setting a first positioning ring 4 fixedly connected to the rotating shaft 2 and a second positioning ring 5 threadedly connected to the rotating shaft 2, the installation and disassembly of the winding drum 3 are facilitated, providing convenience for operators and further improving the efficiency of umbilical cable winding.

[0040] It should be noted that the outer circumferential surface of the second positioning ring 5 is provided with equidistant anti-slip protrusions, which can increase the friction with the hand and facilitate the rotation operation of the second positioning ring 5.

[0041] The working principle of the above embodiments is as follows:

[0042] During the umbilical cable winding operation, the umbilical cable is passed through the cable laying drum 23 and wound onto the winding drum 3. One end of the umbilical cable is inserted into the U-shaped positioning piece 18. Then, the nut 19 is rotated to move the U-shaped positioning piece 18, which clamps and positions the umbilical cable. Then, the rotary motor 12 is started to drive the rotating shaft 2 to rotate through the reduction gearbox 11. The rotating shaft 2 drives the winding drum 3 to rotate and wind the cable. During the winding operation, the servo motor 20 drives the lead screw 7 to rotate. The lead screw 7 drives the first fixing plate 9 to move through the threaded tube 8. The first fixing plate 9 drives the cable laying drum 23 to move back and forth, thereby laying the umbilical cable in the cable laying drum 23 during the winding process, so that the umbilical cable is evenly wound onto the winding drum 3. After the umbilical cable is wound, the second positioning ring 5 can be rotated off the rotating shaft 2. Then, the positioning restriction of the second positioning ring 5 on the winding drum 3 is released, and the winding drum 3 can be removed from the rotating shaft 2.
