Description

Technical Field

[0001] The present application relates to the technical field of submarine hose laying, and in particular to a submarine hose laying and retracting device. Background Art

[0002] In the field of offshore oil and gas development, traditional fluid transportation pipelines are mostly made of carbon steel. Although they perform well in terms of strength and rigidity, their corrosion resistance becomes a major shortcoming when facing the complex and changeable marine environment. Corrosive substances such as acids, alkalis and salts in the ocean pose a serious threat to carbon steel pipelines, causing pipelines to corrode easily, performance degraded, and even premature failure. This not only increases maintenance costs, but also seriously threatens the safety of production operations and the protection of the marine environment.

[0003] Against this backdrop, metal hoses, with their exceptional flexibility and corrosion resistance, offer a novel solution to fluid transport problems in offshore oilfields. This has led to an increasing number of offshore oilfields adopting flexible hoses as fluid transport pipelines. However, due to the soft nature of metal hoses, their shape and position are difficult to precisely control, making them inconvenient to retract and deploy when laid directly.

[0004] Therefore, the present application provides a submarine hose laying and retracting device to solve the above problems. Utility Model Content

[0005] The present application provides a submarine hose laying and retracting device, which aims to solve the problems raised in the background art, such as the difficulty in controlling the shape and position of the existing metal hose due to its soft nature, resulting in inconvenience in laying and retracting.

[0006] To achieve the above objectives, the present application provides the following technical solution: a submarine hose laying and retracting device, comprising at least two parallel bases, two rollers disposed on top of the bases for retracting and retracting the hose, a support structure disposed on the bases at a position corresponding to below the edges of the rollers, a roller assembly disposed on the support structure for supporting the edges of the rollers, and a drive mechanism disposed on the support structure for causing the roller assembly to rotate the rollers;

[0007] The support structure includes a mounting seat symmetrically arranged on the base and a detachable bracket assembly arranged on the mounting seat and connected to the roller assembly, and the driving mechanism is arranged on one of the detachable bracket assemblies; the roller assembly is driven by the driving mechanism, and then the roller is driven to rotate, so that the hose can be automatically retracted and extended. This process is simple, fast and convenient, which greatly improves work efficiency and enhances the automation level of the overall operation. At the same time, the design of the detachable bracket assembly allows the roller assembly and the mounting seat to be disassembled and assembled. This design facilitates the maintenance and care of the roller assembly. When the roller assembly is worn or damaged, it can be quickly replaced, thereby improving the utilization rate of the device.

[0008] Preferably, in order to be suitable for rollers of different diameters, the base is provided with bolt holes distributed in a linear array, and the mounting seat is provided with connecting bolts adapted to the bolt holes; such a design can flexibly adjust the spacing between the symmetrical mounting seats set on the base by changing the positions of the connecting bolts in the bolt holes distributed in the linear array, so as to achieve support for rollers of different diameters, thereby improving the versatility and applicability of the device.

[0009] Preferably, in order to facilitate the disassembly and assembly between the roller assembly and the mounting seat, the detachable bracket assembly includes a connecting bracket arranged at the top of the mounting seat, a pin shaft which passes through the mounting seat and the center position of the connecting bracket in turn and is fixedly connected to the connecting bracket, a first fixing groove provided on the outside of one end of the pin shaft, a first pressure plate which is inserted into the first fixing groove and abuts against one side of the mounting seat, and a first fixing bolt provided on the first pressure plate, the first pressure plate is fixedly connected to the mounting seat by the first fixing bolt; the first pressure plate is fixed to the mounting seat by the first fixing bolt, and the connection or separation between the connecting bracket and the mounting seat can be conveniently and quickly achieved by utilizing the plug-in relationship between the first pressure plate and the first fixing groove. This design greatly simplifies the disassembly and assembly process of the detachable bracket assembly and improves work efficiency.

[0010] Preferably, in order to facilitate full contact between the roller assembly and the edge of the drum and support rotation, the connecting frame is tilted toward one end near the center of the base; the design of the tilted connecting frame enables the roller assembly to always maintain a close fit with the edge of the drum when the roller assembly is driven by the driving assembly to drive the drum to rotate, reducing the possibility of sliding or jumping, thereby providing more stable and reliable support.

[0011] Preferably, in order to further improve the utilization rate of the device, the roller assembly includes rollers symmetrically arranged at both ends of the connecting frame and transversely passing through the connecting frame, a second fixing groove opened on the outside of one end of the roller, a second pressure plate inserted in the second fixing groove and abutting the side of the connecting frame, a second fixing bolt arranged on the second pressure plate, and a support wheel fixedly arranged on the roller and in contact with the edge of the roller, and the second pressure plate is fixedly connected to the connecting frame by the second fixing bolt; with this design, when a separate support wheel on the connecting frame is damaged, there is no need to disassemble the entire roller assembly or the connecting frame, and the second pressure plate and the roller can be easily removed by loosening the second fixing bolt, and then the damaged support wheel can be replaced, which greatly improves maintenance efficiency.

[0012] Preferably, in order to facilitate the rotation of the roller, the driving mechanism includes a gear box fixedly arranged on one side of the connecting frame, a small gear rotatably arranged in the gear box, a large gear fixedly sleeved on one of the rollers of the connecting frame and meshing with the small gear, and a motor fixedly arranged on the side of the gear box away from the connecting frame for driving the small gear to rotate; the meshing design of the small gear and the large gear can directly and effectively transmit the rotational power of the motor to the roller, so that the roller assembly drives the rotation of the roller, which is simple and convenient.

[0013] The submarine hose laying and retracting device drives the roller assembly through a driving mechanism, which in turn drives the drum to rotate, thereby realizing automatic retraction and deployment of the hose. This process is simple, fast and convenient, greatly improving work efficiency and enhancing the overall automation level of the operation.

[0014] The submarine hose laying and retracting device is provided with a detachable bracket assembly, which allows the roller assembly and the mounting seat to be disassembled and assembled. This design facilitates the maintenance and upkeep of the roller assembly.

[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] Example 1

[0028] This embodiment provides a submarine hose laying and retracting device, such as Figure 1 - Figure 4 As shown, the retracting and releasing device includes at least two parallel bases 1, rollers 2 arranged at the top of the two bases 1 for retracting and releasing the hose, a support structure 3 arranged on the base 1 at a position below the edge of the corresponding roller 2, a roller assembly 4 arranged on the support structure 3 for supporting the edge of the roller 2, and a driving mechanism 5 arranged on the support structure 3 for causing the roller assembly 4 to drive the roller 2 to rotate; the support structure 3 includes a mounting seat 31 symmetrically arranged on the base 1 and a detachable bracket assembly 32 arranged on the mounting seat 31 and connected to the roller assembly 4, and the driving mechanism 5 is arranged on one of the detachable bracket assemblies 32.

[0029] During use, when the hose needs to be retracted or unfolded, the driving mechanisms 5 on the two bases 1 are first started to drive the roller assemblies 4 on the corresponding detachable bracket assemblies 32 connected to the base 1 to rotate. Since the roller assemblies 4 on the two detachable bracket assemblies 32 provided on the base 1 are in contact with the edges of the drum 2, when the driving mechanism 5 drives the roller assemblies 4 on one of the detachable bracket assemblies 32 connected to the base 1 to rotate, the drum 2 will start to rotate. At the same time, the roller assembly 4 on the other detachable bracket assembly 32 will also rotate synchronously with the drum 2, and then the drum 2 can stably rotate between the two detachable bracket assemblies 32 provided on the base 1. Then, as the drum 2 rotates, the hose will be gradually wrapped around or unfolded on the drum 2. During use, the detachable bracket assembly 32 and the mounting seat 31 can be disassembled and assembled according to the usage of the roller assembly 4 to achieve replacement or maintenance of the roller assembly 4.

[0030] Specifically, the detachable bracket assembly 32 includes a connecting frame 321 provided at the top of the mounting base 31, a pin 322 that passes through the center of the mounting base 31 and the connecting frame 321 in sequence and is fixedly connected to the connecting frame 321, a first fixing groove 323 provided on the outer side of one end of the pin 322, a first pressing plate 324 inserted into the first fixing groove 323 and abutting against one side of the mounting base 31, and a first fixing bolt 325 provided on the first pressing plate 324. The first pressing plate 324 is fixedly connected to the mounting base 31 via the first fixing bolt 325.

[0031] When the roller assembly 4 as a whole is worn out after being used for a period of time, the first fixing bolt 325 can be loosened and the first pressure plate 324 can be pulled out from the corresponding first fixing groove 323. At this time, the fixation between the first pressure plate 324 and the mounting seat 31 can be released. Thereafter, the pin shaft 322 can be pulled out from the through-hole of the mounting seat 31, and the connecting frame 321 and the roller assembly 4 set thereon can be easily removed from the mounting seat 31. After replacement or maintenance, the pin shaft 322 can be inserted into the through-hole of the mounting seat 31, and the first pressure plate 324 can be inserted into the first fixing groove 323. Finally, the first fixing bolt 325 can be tightened, and the entire roller assembly 4 can be easily replaced or maintained.

[0032] Among them, in order to facilitate the roller assembly 4 to fully contact with the edge of the drum 2 and support the rotation, the connecting frame 321 is tilted toward one end near the center position of the base 1; the design of the inclined connecting frame 321 enables the roller assembly 4 to always maintain a close fit with the edge of the drum 2 when the driving mechanism 5 drives the roller assembly 4 to rotate, reducing the possibility of sliding or jumping, thereby providing more stable and reliable support.

[0033] Furthermore, the roller assembly 4 includes rollers 41 symmetrically arranged at both ends of the connecting frame 321 and transversely passing through the connecting frame 321, a second fixing groove 42 provided on the outer side of one end of the roller 41, a second pressure plate 43 inserted into the second fixing groove 42 and abutting against the side of the connecting frame 321, a second fixing bolt 44 provided on the second pressure plate 43, and a support wheel 45 fixedly provided on the roller 41 and in contact with the edge of the drum 2. The second pressure plate 43 is fixedly connected to the connecting frame 321 by the second fixing bolt 44.

[0034] When the separate support wheel 45 on the roller assembly 4 is worn, the second fixing bolt 44 can be loosened and the second pressure plate 43 can be pulled out from the corresponding second fixing groove 42. At this time, the fixation of the second pressure plate 43 to the connecting frame 321 can be released. Thereafter, the roller 41 can be pulled out from the through-hole of the connecting frame 321, and the connecting frame 321 and the support wheel 45 on the roller 41 set thereon can be easily removed from the connecting frame 321. After replacement or maintenance, the roller 41 can be inserted into the through-hole of the connecting frame 321, and then the second pressure plate 43 is inserted into the second fixing groove 42. Finally, the second fixing bolt 44 is tightened, and the separate support wheel 45 on the roller assembly 4 can be easily replaced or maintained.

[0035] Furthermore, the driving mechanism 5 includes a gear box 51 fixedly mounted on one side of the connecting frame 321, a small gear 52 rotatably mounted in the gear box 51, a large gear 53 fixedly mounted on one of the rollers 41 of the connecting frame 321 and meshing with the small gear 52, and a motor 54 fixedly mounted on a side of the gear box 51 away from the connecting frame 321 for driving the small gear 52 to rotate.

[0036] When it is necessary to start the driving mechanism 5 to drive the roller assembly 4 to rotate so that the drum 2 can retract and release the hose, the motor 54 provided on the corresponding detachable bracket assembly 32 on the base 1 can be started. At this time, the motor 54 will drive the small gear 52 connected to it to rotate. Since the small gear 52 is engaged with the large gear 53 on one of the rollers 41 on the detachable bracket assembly 32, as the small gear 52 rotates, the corresponding roller 41 on the detachable bracket assembly 32 will also rotate synchronously, so that the roller 41 can synchronously drive the support wheel 45 connected thereto to rotate. Since the motor 54 contacts the edge of the drum 2, when one of the support wheels 45 provided on the detachable bracket assembly 32 rotates, the drum 2 will rotate synchronously. At the same time, the other support wheel 45 provided on the detachable bracket assembly 32 will also synchronously assist the rotation of the drum 2 to ensure stable rotation of the drum 2.

[0037] It should be noted that the large gear 53 is fixedly connected to the roller 41 on the higher inclined end of the connecting frame 321. Since the support wheel 45 provided on the roller 41 is away from the center point of the drum 2, when the motor 54 drives the large gear 53 to rotate through the small gear 52, the connection point between the large gear 53 and the roller 41 will generate a larger torque, which can more effectively drive the drum 2 to rotate.

[0038] Example 2

[0039] Different from Example 1, in order to improve the versatility and applicability of the device, the base 1 is provided with bolt holes 11 distributed in a linear array, and the mounting seat 31 is provided with connecting bolts 311 that are compatible with the bolt holes 11; with this design, by changing the position of the connecting bolts 311 in the bolt holes 11 distributed in a linear array, the spacing between the symmetrical mounting seats 31 set on the base 1 can be flexibly adjusted to achieve support for rollers 2 of different diameters.

[0040] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
