Description

Technical Field

[0001] This application relates to the technical field of cable equipment, and more particularly to a cable laying device and a cable winding and unwinding device. Background Technology

[0002] In offshore oil exploration operations, underwater work equipment is typically used. Underwater operations are highly dangerous and difficult, and relying solely on human operation cannot guarantee safety. Underwater operations usually require the use of cables for securing equipment, and cable deployment and retrieval devices are used to lower and retrieve the equipment, ensuring safety. Because the sea surface and underwater environment are unstable, the ship and equipment remain in motion due to wind, waves, and currents during cable deployment and retrieval.

[0003] In existing technologies, cable reeling and deployment devices are relatively large in size, with a wide span after the cables are stored. The cable laying method typically involves laying the cables along the axis of the cable drum. During cable reeling and deployment, the ship's rolling motion can affect the cable reeling and deployment process. The cable reeling and deployment device cannot adjust the laying angle, leading to cable tangling during the process and severely affecting its usability. Summary of the Invention

[0016] Secondly, this application also provides a cable winding and unwinding device, which includes a cable laying device, the cable laying device being the aforementioned cable laying device.

[0017] Furthermore, the cable winding and unwinding device includes a roller assembly, which includes a roller body, a second power mechanism, a second transmission mechanism, and a mounting bracket.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] like Figures 1 to 8 As shown, in a first aspect, the technical solution of this application provides a cable laying device and a cable winding and unwinding device. The cable laying device includes a sliding component 20 and a cable guiding component 30. The sliding component 20 is electrically connected to a control component and can slide along the length direction of the roller component 10. The cable guiding component 30 includes a first correction mechanism 31 and a second correction mechanism 32. The first correction mechanism 31 is rotatably connected to the sliding component 20, and the second correction mechanism 32 is rotatably connected to the first correction mechanism 31. The first correction mechanism 31 ensures that the cable remains vertically downward during the winding and unwinding process when the hull is pitching forward and backward. The second correction mechanism 32 ensures that the cable remains vertically downward during the winding and unwinding process when the hull is pitching left and right. Maintaining the vertical downward direction during the winding and unwinding process can prevent the cable from becoming tangled due to swinging during the winding and unwinding process, effectively solving the problem that the cable laying device in the prior art cannot adjust the cable laying angle, resulting in tangled cables during the winding and unwinding process.

[0048] It should be noted that the diameter of the cable is usually thick, and the overall size of the cable laying equipment is large, requiring the use of a control system. If the roller assembly 10 and the cable guide assembly 30 are not used to guide the position of the cable, the cable will overlap at a certain position, resulting in uneven force on some roller assemblies 10. Since the roller assembly 10 is usually a hollow wooden or iron material, uneven force can cause crushing, leading to the failure of the roller assembly and even affecting the normal operation of the cable laying equipment. This can cause the other end of the cable to be unable to be retracted or released in time, affecting operational safety.

[0049] like Figure 1 and Figure 3As shown, in this embodiment, the first correction mechanism 31 includes a tubular component 311 and a connecting arm 312. A first slewing bearing 313 is provided between the first end of the tubular component 311 and the sliding assembly 20. The second correction mechanism 32 is partially located inside the tubular component 311 and is rotatably connected to the connecting arm 312. The first slewing bearing 313 enables relative rotation between the tubular component 311 and the sliding assembly 20. Specifically, the outer ring of the first slewing bearing 313 is fixedly connected to the sliding assembly 20, and the inner ring of the first slewing bearing 313 is fixedly connected to the tubular component 311. The center of gravity of the tubular component 311 is low, and under the action of gravity, the end of the tubular component 311 is always kept below the axis of the tubular component 311, ensuring that the tubular component 311 always faces downwards even during bumps. The connecting arm 312 is used to install a rotating bearing, and the second correction mechanism 32 is installed by a fixed shaft passing through the rotating bearing.

[0050] like Figure 1 and Figure 3 As shown, in this embodiment, the second correction mechanism 32 includes a guide wheel 321 with a groove tangent to the axis of the tubular component 311. The first correction mechanism 31 is bolted to the inner ring of the first slewing bearing 313. To reduce interference from other environments, the tubular component 311 should oscillate with factors such as the ship's tilt and cable angle deflection. The tubular component 311 is connected to the sliding assembly 20 via a slewing bearing, allowing the tubular component 311 and the guide wheel 321 to rotate at a certain angle in the vertical plane. A load pin is integrated at the center of the guide wheel 321 and connected to the connecting arm 312. A pressure sensor is installed on the load pin to measure the force received by the guide wheel 321, which is then converted into real-time cable tension. The cable laying equipment can be adjusted based on the transmitted pressure data, and an alarm can be issued and the equipment stopped when the pressure is too high. Monitoring the cable tension allows for the acquisition of cable usage data, enabling timely assessment of the cable's condition and preventing operational safety issues caused by cable damage.

[0051] like Figure 3 and Figure 4 As shown in the technical solution of this embodiment, the cable guide assembly 30 further includes a third correction mechanism 33. The third correction mechanism 33 is disposed inside the tubular component 311 near one end of the sliding assembly 20, and is electrically connected to the control assembly. The cable passes through the third correction mechanism 33 and cooperates with the guide wheel 321. When the cable is being wound up or down, the position of the cable along the length direction of the roller assembly 10 can be judged in a timely manner to ensure that the position of the cable in this direction will not deviate significantly, further avoiding the phenomenon of cable tangling.

[0052] like Figure 4As shown, in the technical solution of this embodiment, the third correction mechanism 33 includes a first correction component 331, a second correction component 332, a first mounting base 333, a first position sensor 334, and a second position sensor 335. The first correction component 331 and the second correction component 332 are slidably connected to the first mounting base 333. The first position sensor 334 and the second position sensor 335 are both fixedly mounted on the first mounting base 333. The first correction component 331 has a first correction position that cooperates with the first position sensor 334, and the second correction component 332 has a second correction position that cooperates with the second position sensor 335. Specifically, the first correction component 331 and the second correction component 332 are both vertically arranged. The third correction mechanism 33 also includes a second mounting base 336, a first elastic element 337, and a second elastic element 338. Both the first mounting base 333 and the second mounting base 336 are provided with sliding grooves. The two ends of the first correction component 331 and the second correction component 332 are located in the sliding grooves and can slide to a certain extent. The ends of the first correction component 331 and the second correction component 332 that pass through the second mounting base 336 are provided with sliders. When the first correction component 331 is in the first correction position, the slider of the first correction component 331 cooperates with the first position sensor 334 to send position information to the control component. The control component adjusts the sliding component 20 according to the position information. The second correction component 332 works on the same principle as the first correction component 331, except that it is opposite to the first correction component 331 in terms of the direction of cable deflection. The first elastic element 337 and the second elastic element 338 are configured to reset the first correction element 331 and the second correction element 332 after adjustment, thus avoiding the problem of continuous information reporting. In a preferred embodiment, multiple first elastic elements 337 and second elastic elements 338 can be configured, respectively connected to both ends or more segments of the second correction element 332 and the first correction element 331 to meet the reset requirement.

[0053] It should be noted that the first correction component 331 and the second correction component 332 can be composed of a correction shaft and a sliding bushing. The correction shaft is installed inside the sliding bushing, and the correction shaft is connected to the upper and lower sliding blocks by a pin. The sliding blocks and the spring mounting plate are connected by a spring. During the winding and unwinding of the cable, the cable is located between the left and right sliding bushings. When the cable deflects to the left or right, the force generated will cause the correction shaft to pull the slider to slide under the position sensor. When the slider touches the position sensors on both sides, it will send a signal to the motor, controlling the motor to rotate forward or backward to control the movement direction of the sliding component 20, thereby realizing the correction function.

[0054] like Figure 1 and Figure 2As shown in the technical solution of this embodiment, the cable guide assembly 30 further includes a metering mechanism 34. The metering mechanism 34 includes a mounting frame 341 and a metering element 342. The mounting frame 341 is fixedly connected to the tubular component 311, and the metering element 342 is connected to the wheel groove by a cable. The mounting frame 341 is fixed to the upper part of the tubular component 311 by bolts. Under the force of the mounting frame 341, the metering element 342 presses down on the cable. The sliding of the cable during winding and unwinding drives the metering element 342 to rotate, thereby realizing the calculation of the cable. Specifically, the measuring component 342 also includes an encoder 3421, a measuring wheel 3422, a third elastic element 3423, a driven wheel 3424, and a pressure rod 3425. The third elastic element 3423 applies pressure to the pressure rod 3425, pressing the rotating shaft of the measuring wheel 3422 in the direction of the cable, increasing the friction between the cable and the measuring wheel 3422. Under the action of friction, when the cable is wound up and released, the cable will drive the measuring wheel 3422 to rotate. The measuring wheel 3422 drives the driven wheel 3424 to rotate through the chain. The driven wheel 3424 drives the encoder 3421 to rotate, thereby recording and transmitting data to the control component.

[0055] It should be noted that a large sprocket is mounted on the shaft of the measuring wheel 3422, and a small sprocket is mounted on the driven wheel 3424. Counting is performed via chain drive, which is more accurate. Furthermore, a coupling is installed between the output end of the encoder 3421 and the driven wheel 3424 to protect the encoder from damage due to excessive instantaneous stress. During cable winding and unwinding, the tension spring presses the measuring wheel 3422 against the outer wall of the cable. As the cable winds up and down, the measuring wheel 3422 rotates. The drive shaft of the measuring wheel 3422 is connected to the small sprocket, and the rotation of the measuring wheel 3422 drives the small sprocket. The encoder is fixed to the mounting bracket 341. The output shaft of the encoder 3421 is connected to the drive shaft and the large sprocket via a coupling. The small sprocket drives the large sprocket to rotate via a chain, which in turn drives the drive shaft and the output shaft of the encoder 3421 to rotate. The number of rotations is then converted into the cable winding and unwinding length.

[0056] like Figure 5 and Figure 9 As shown, in the technical solution of this embodiment, the sliding component 20 includes a first power mechanism 21, a first transmission mechanism 22 and a sliding mechanism 23. The output end of the first power mechanism 21 is connected to the input end of the first transmission mechanism 22, and the sliding mechanism 23 is fixedly connected to the first transmission mechanism 22.

[0057] like Figure 5 and Figure 6As shown, in this embodiment, the first power mechanism 21 is an electric motor, the first transmission mechanism 22 includes a first sprocket 221 and a chain 222, and the sliding mechanism 23 includes a traction seat 231, with both ends of the traction seat 231 connected to the chain 222. The first sprocket 221 is connected to the first power mechanism 21. The electric motor can provide stable output power and its rotation speed can be controlled by controlling the voltage or current. The arrangement of the first sprocket 221 and the chain 222 can precisely control the sliding distance of the sliding component 20.

[0058] like Figure 6 As shown, in this embodiment, a third position sensor 2211 is provided on the first sprocket 221. The third position sensor 2211 is electrically connected to the control component and is used to record and report the position of the first sprocket 221. The third position sensor 2211 is an absolute position sensor used to transmit data on the rotation angle of the first sprocket 221.

[0059] like Figure 7 and Figure 8 As shown, in the technical solution of this embodiment, the first transmission mechanism 22 further includes a second sprocket 223, a first tensioning member 224 and a second tensioning member 225. The first tensioning member 224 is disposed below the chain 222, and the second tensioning member 225 is fixedly connected to the second sprocket 223. The second tensioning member 225 is used to adjust the distance between the first sprocket 221 and the second sprocket 223.

[0060] Specifically, the first tensioning element 224 includes a tensioning wheel 2241, a sliding seat 2242, a lifting block 2243, a lifting seat 2244, a fixed support seat 2245, and a lead screw 2246. The tensioning wheel 2241 is slidably connected to the sliding seat 2242 via a shaft and bearing. The lifting block 2243 is slidably connected to the sliding seat 2242. The fixed support seat 2245 is fixedly positioned. The lifting seat 2244 and the lead screw 2246 are connected by a thread. The rotation of the lead screw 2246 causes the lifting seat 2244 to move vertically, thereby causing the lifting block 2243 to slide. The lifting block 2243 can lift the tensioning wheel 2241 to slide vertically, thus realizing the sliding of the tensioning wheel 2241. The vertical displacement of the tensioning wheel 2241 can compress the tension of the chain. The second tensioning component 225 includes a sliding block 2251, a lead screw 2252, and a nut 2253. In use, after unscrewing the nut 2253, the second sprocket 223 is adjusted via the sliding block 2251. After adjustment, the nut 2253 is tightened to fix the second sprocket 223. It should be noted that in a preferred embodiment, there can be two sliding blocks 2251, lead screw 2252, and nuts 2253. When two are used, the position of the second sprocket 223 can be adjusted by adjusting the fit between the two nuts 2253 and the lead screw 2246, thereby adjusting the chain tension and facilitating disassembly.

[0061] like Figures 9 to 11 As shown, in the technical solution of this embodiment, the cable laying device also includes a support assembly 40, a roller assembly 10 is disposed in the support assembly 40, the support assembly 40 includes a sliding rail 41, the sliding mechanism 23 also includes a sliding seat 232, the sliding seat 232 is slidably connected to the sliding rail 41, and the sliding seat 232 is fixedly connected to the traction seat 231. Specifically, the support assembly 40 includes a sliding rail 41, a sprocket box 42, a water receiving tank 43, a bottom base 44, a drain outlet 45, a detachable top plate, and a mounting beam. The mounting beam is used to install the sprocket box 42 and the first tensioning member 224 in the sliding assembly 20. Multiple first tensioning members 224 are installed, and multiple members work together to adjust the working state of the chain 222. The bottom of the support assembly 40 is provided with a four-directional guide device for guidance and limitation. The roller assembly 10 can be inserted from the top of the support assembly 40. During the insertion process, it is guided and limited by the four-directional guide device. After the bottom base 44 is inserted, it is fixed by welding and then positioned. The bottom base 44 serves as the installation interface for the roller assembly 10 and needs to ensure the horizontality of the roller assembly 10 after installation. The mounting beam and the sliding rail 41 need to be welded to the support assembly 40. After welding, they are then processed to ensure the straightness of the mounting beam and the sliding rail 41.

[0062] It should be noted that limit switches are also provided at both ends of the sliding track 41. The limit switches are used to control the left and right sliding limits of the cable laying equipment during cable winding and unwinding, ensuring that the cable winding and unwinding can be reversed. The second sprocket 223 is also equipped with a lead screw 2252, nut 2253, mounting shaft, bearing, etc. on one side. The front and rear mounting plates of the sprocket box 42 have sliding grooves. The sliding block 2251 on the mounting shaft can control the second sprocket 223 to slide along the lead screw 2252, thereby controlling the tension of the sprocket. The nut 2253 on the outside of the sprocket box 42 is used for positioning and locking. Both the first sprocket 221 and the second sprocket 223 are sprocket sets, which can be shifted through a mechanism such as a paddle to control different speed requirements, reducing the requirements on the first power mechanism 21 and also reducing the complexity of the design of the first transmission mechanism 22.

[0063] like Figure 9 As shown, in a second aspect, this application also provides a cable winding and unwinding device, which includes a cable laying device, specifically the aforementioned cable laying device. Using the aforementioned cable laying device, the cable always remains vertically downward during winding and unwinding. Maintaining a vertically downward orientation during winding and unwinding prevents the cable from becoming tangled due to swinging, effectively solving the problem of cable tangling during winding and unwinding caused by the inability of existing cable laying devices to adjust the laying angle. Furthermore, it can be adjusted through its own mechanisms.

[0064] like Figures 12 to 17 As shown, in this embodiment, the cable winding and unwinding device includes a roller assembly 10. The roller assembly 10 includes a roller body 11, a second power mechanism 12, a second transmission mechanism 13, and a mounting bracket 14. Reinforcing rings 111 are provided at both ends of the roller body 11. The second transmission mechanism 13 includes a second slewing bearing 131 and a transmission gear 132. The reinforcing rings 111 are fixedly connected to the outer ring of the second slewing bearing 131, and the mounting bracket 14 is fixedly connected to the inner ring of the second slewing bearing 131. The transmission gear 132 meshes with the outer ring of the second slewing bearing 131. Specifically, the roller body 11 includes a flange for installation. The flange may even have weight-reducing holes 112 to reduce the weight of the cable winding and unwinding device. The roller body 11 is welded from high-strength steel plates and has axial and radial reinforcing ribs 113 welded inside. The reinforcing ribs 113 ensure that the roller body 11 does not deform axially or radially during operation. Furthermore, the reinforcing rib 113 has a chamfer at the bottom where it connects with the roller body 11 to connect the part inside the roller body 11 divided by the reinforcing rib 113, so as to prevent water from accumulating inside and allow water to flow out from inside the roller.

[0065] It should be noted that the second power mechanism 12 consists of two units located on both sides of the drum body 11, which provide power to the drum assembly 10 through connection with the second transmission mechanism 13. Specifically, the drum body is driven by a motor and a reducer 134 at each end. The motors are variable frequency motors with independent forced cooling fans, anti-condensation heating elements, and temperature sensors. If the variable frequency drive device or motor fails, the drum body 11 can be driven by one motor, in which case the drum speed will decrease. The output shaft of the motor and the input shaft of the reducer 134 are connected by a safety coupling 133. The safety coupling 133 protects the cable and drum body 11 from overload. When the driving torque exceeds the safety torque set by the safety coupling 133, the safety coupling 133 slips to protect the drum body and cable. The safety coupling 133 is equipped with a brake wheel. Braking device: The drum body 11 has an automatic fault-tolerant mechanical brake to realize the parking brake and emergency brake of the drum body 11. The mechanical brake is operated by a push rod controlled by a small motor.

[0066] like Figure 14 As shown, the second transmission mechanism 13 also includes a second slewing bearing 131 and a transmission gear 132. The output shaft of the reducer 134 is connected to the transmission gear 132. By reducing speed and increasing torque, it drives the external gear ring on the outer ring 1312 of the second slewing bearing 131 to rotate. The outer ring 1312 is fixedly connected to the mounting reinforcing ring 111 on the flange by bolts. The outer ring 1312 is provided with a radially extending stop, which mates with the mounting reinforcing ring 111. The inner ring 1311 of the second slewing bearing 131 is bolted to the mounting bracket reinforcing ring 141 on the mounting bracket 14. The inner ring 1311 is provided with a radially extending stop, which mates with the mounting bracket reinforcing ring 141. It should be noted that both the mounting reinforcing ring 111 and the mounting bracket reinforcing ring 141 are fixedly connected to the drum body 11 and the mounting bracket 14 by welding.

[0067] like Figures 18 to 19 As shown, in the technical solution of this embodiment, the roller assembly 10 further includes a locking mechanism 15. The locking mechanism 15 includes a locking shaft 151, a retaining ring 152, a retaining ring groove 153, and a detector 154. The locking shaft 151 is fixedly connected to the retaining ring 152. The shaft of the locking shaft 151 can be inserted into the detector 154. The retaining ring groove 153 is fixedly connected to the first side of the detector 154. The second side of the detector 154 is fixedly connected to the mounting bracket 14. When the locking shaft 151 is inserted into the detector 154, the rotation of the locking shaft 151 can cause the retaining ring 152 to be located in the retaining ring groove 153. The detector 154 is electrically connected to the control component.

[0068] like Figure 15 , Figure 18 and Figure 19 As shown, the flange of the roller body 11 has a large weight-reducing hole 112 and a locking mounting hole 155. Two locking mechanisms 15 are provided on one side of the mounting bracket 14 to prevent the roller body 11 from rotating during transportation and storage. A detector 154 is mounted on the locking mounting hole 155.

[0069] The position of the locking shaft 151 will be indicated. If the locking shaft 151 is not pulled out, the detector 154 will send a signal to the motor, and the control system will lock the drive signal of the roller assembly 10, preventing the roller assembly 10 from moving. When the handle of the locking shaft 151 is turned, the retaining ring 152 fixedly connected to the locking shaft 151 will disengage from the retaining ring groove 153, thus facilitating the insertion and removal of the locking shaft 151. A top bar is provided between the left and right roller support frames to connect and increase the overall rigidity and deformation. A ladder is installed on the roller support frame for easy maintenance and operation by operators.

[0070] like Figure 20 As shown in the technical solution of this embodiment, the cable winding and unwinding device further includes a spray assembly 50, which includes a centrifugal pump 51 and a spray frame 52. The spray frame 52 is disposed on the top of the roller assembly 10, and the centrifugal pump 51 is used to provide liquid pressure. The spray assembly 50 also includes a filter, hose, quick connector, rigid pipe, and pipe clamp, etc. Its main function is to spray water liquid onto the roller cable through the circulation action of the centrifugal pump 51, thereby cleaning and cooling the cable. The sprayed liquid is collected in the water receiving tank 43 of the support assembly 40. The spray frame 52 is constructed of rigid pipes and is fixed above the support assembly 40 via pipe supports or other means. The rigid pipes are connected to each other as a single, internally interconnected unit using right-angle elbows and tees. Several small water outlets are located at the bottom of each rigid pipe. The outlet of the centrifugal pump 51 is connected to the main rigid pipe via a flexible hose, and the hose is connected to the rigid pipe via a quick-connect coupling, facilitating quick installation, disassembly, and maintenance of the spray assembly's piping. The inlet of the centrifugal pump 51 is connected to a flexible hose, and the water outlet is located at the lowest point of the water collection tank 43 on the support assembly 40 via a quick-connect coupling. The support assembly 40 has several drain outlets 45 in various directions to prevent excessive water accumulation in the water collection tank 43 or to prevent the lowest liquid level from being off-center.

[0071] It should be noted that in this embodiment, the cable winding device is also equipped with a portable control console for controlling the winding and unwinding of the cable on the drum. During the cable winding process, automatic cable routing can be achieved through PLC control. When the cable needs to be moved to the next layer, the cable routing device automatically reverses its rotation through program control. If the cable deviates from its position during the winding process, the cable routing device can be manually controlled to force cable routing and adjust the cable to the appropriate position.

[0072] The cable laying function of this application can realize both automatic and manual forced laying modes. It has multiple correction mechanisms, metering mechanisms, and multiple cooperating sensors. It can simultaneously convert the cable offset, cable length and speed, and cable position during the cable laying process into electrical signals and feed them back to the control component, thereby enabling automatic cable correction, automatic reading of cable length and speed information, and automatic reading of cable position information. The sliding component 20 is chain-driven, and together with the horizontal slide rail and slider, it can realize long-distance cable laying operations and has better structural strength than the screw drive. At the same time, the design of the manually adjustable chain tensioning mechanism increases the stability of the cable laying process. The guide wheel 321 in the second correction mechanism 32 has a tension monitoring function, which feeds back the force acting on the guide wheel 321 to the control system and converts it into cable tension. The cable winding and unwinding device has a self-circulating spray system: the convenient pipeline connection method can realize the quick disassembly and assembly of the system; the connection between the water tank and the spray pump can realize the recycling of spray liquid.
