Description

Technical Field

[0001] This invention relates to the field of hose forming device technology, and specifically to a marine floating hose forming device. Background Technology

[0002] Marine floating hoses are large-diameter flexible composite hoses that can float on the sea surface for extended periods and are used for transporting crude oil or refined oil products at sea. The core of these hoses is a multi-layered structure consisting of rubber, fiber, steel wire, and a buoyancy layer. They combine high strength, high flexibility, and stable buoyancy, making them a key piece of equipment for FPSO (Floating Production Station) export and offshore oil loading and unloading.

[0003] During production, the marine floating hose uses a steel core as a forming mold and is prepared by a winding production line. The core rotates by being placed on a forming device, while inner rubber, reinforcing fabric and isolation fabric placed on multiple air shafts are wound around the core, thus forming the final shape.

[0004] However, the support frame for placing the mandrel in traditional molding equipment is difficult to adjust according to different mandrel lengths. This is because the mandrel is a rigid shaft with an unchangeable length. The two ends of the mandrel are fixed to the brackets, and the spacing between the brackets is fixed. Therefore, only a single standard length can be produced. If the length is changed, the entire mandrel needs to be replaced, which is quite troublesome. Furthermore, as the mandrel is wrapped, it becomes heavier and heavier, and the overall load continues to increase. Without supporting components below, the mandrel is prone to sinking or deflection, which affects the molding accuracy of the product. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide a marine floating hose forming device, which solves the technical problems in the related art where it is difficult to adjust the distance of the support when processing different tube cores, and the tube cores gradually become heavier during the processing, thus causing them to sink.

[0006] At least one embodiment of the present invention provides a marine floating hose forming device, including a placement frame and a placement plate, and further including a fixed moving frame, a sliding moving frame, an air shaft, a translation drive assembly, and a support anti-sinking assembly. The fixed moving frame is fixedly installed on the placement frame, the sliding moving frame is disposed on the placement frame via a side sliding assembly, the air shaft is disposed on the placement plate via a sliding seat, two translation drive assemblies are provided, and both the placement frame and the placement plate are provided with translation drive assemblies for driving the sliding seat and the sliding moving frame to move horizontally, the support anti-sinking assembly is disposed on the placement frame for supporting the tube core, the sliding seat is slidably mounted on the placement plate via a rotating ring, and the sliding seat is rotatably mounted on the rotating ring, three air shafts are rotatably mounted on the side of the sliding seat, and the sliding seat is located on the side of the placement frame.

[0007] When adjusting the distance between the fixed movable frame and the sliding movable frame, the side sliding assembly further includes side pulleys and a side sliding bracket. Four side pulleys are provided, and all four side pulleys are in contact with the top of the placement frame. The side sliding bracket is fixedly installed on the top of the four side pulleys, and the sliding movable frame is fixedly connected to the side sliding bracket.

[0008] To drive the movement of the sliding frame and the sliding seat, the translation drive assembly further includes a support cover, a reciprocating screw, and a motor. The support cover is fixedly installed on the side of both the placement frame and the placement plate. The reciprocating screw is rotatably installed inside the support cover, and a matching slider is installed on the reciprocating screw. The motor is installed on the side of the support cover, and the output end of the motor is coaxially and fixedly connected to the reciprocating screw. The two sliders on the two reciprocating screws are respectively fixedly connected to the side of the sliding frame and the sliding seat.

[0009] When support is required during the processing of the tube core, the support and anti-sinking assembly further includes a mounting frame, electric push rods, a lifting frame, a left-right adjustment assembly, and a stabilizing assembly. The mounting frame is slidably mounted on the placement frame, and the side of the mounting frame is fixedly connected to the side slide frame via a connecting rod. Two sets of electric push rods are provided, each set containing two electric push rods. Both sets of electric push rods are mounted on the mounting frame, and the lifting frame is fixedly mounted on the output end of each set of electric push rods. The left-right adjustment assembly is mounted on the lifting frame, and the stabilizing assembly is located on the side of the left-right adjustment assembly. The left-right adjustment assembly includes an adjustment cover, sliding blocks, and support rollers. Two adjustment covers are provided, each fixedly mounted on two lifting frames. Two sliding blocks are slidably mounted on the side of each adjustment cover. Two rollers are provided, and the supporting roller is rotatably installed between each pair of opposing sliding blocks. The stabilizing assembly includes a vertical slide rail, a stabilizing rod, a lower insertion rod, and a limiting assembly. Two vertical slide rails are fixedly installed on the side of the adjusting cover. The stabilizing rod is slidably installed on the side of the two vertical slide rails. The lower insertion rod is fixedly installed on the side of the sliding block. The limiting assembly is located on the side of the vertical slide rail and includes a limiting plate and a limiting post. The limiting plate is fixedly installed on the side of the vertical slide rail, and the limiting post is slidably installed through the side of the limiting plate. The stabilizing rod has several slots that are adapted to the bottom end of the lower insertion rod. Slots that are adapted to the side of the limiting post are opened on both sides of the stabilizing rod. When the limiting post and the slot are at the same horizontal position, the bottom end of the lower insertion rod is inserted into the slot of the stabilizing rod.

[0010] The marine floating hose forming device provided in this embodiment of the invention, compared with the prior art, can adjust the distance between the fixed moving frame and the sliding moving frame according to the length of different tube cores by cooperating with the fixed moving frame, the sliding moving frame, the air shaft, the translation drive component and the support anti-sinking component. This allows for adjustment and placement when processing tube cores of different lengths without the need to change equipment, which is more convenient. In the process of winding material around the core, as the diameter and weight of the core increase, the core can be supported by the anti-sinking component to prevent it from sinking. Furthermore, the support roller can be height adjusted according to the thickness of the core, thus preventing subsequent material winding from affecting the core. Attached Figure Description

For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus. It is understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, this invention illustrates a marine floating hose forming device according to an embodiment of the present invention, including a placement frame 1 and a placement plate 2, as well as a fixed moving frame 3, a sliding moving frame 4, an air shaft 5, a translation drive assembly, and a support anti-sinking assembly. The fixed moving frame 3 is fixedly installed on the placement frame 1, the sliding moving frame 4 is set on the placement frame 1 via a side sliding assembly, the air shaft 5 is set on the placement plate 2 via a sliding seat 23, and two translation drive assemblies are provided, one on the placement frame 1 and one on the placement plate 2, for driving the sliding seat 23 and the sliding moving frame 4 to move horizontally. The support anti-sinking assembly is set on the placement frame 1 for supporting the hose core.

[0021] When processing and shaping marine floating hoses, such as Figure 7 and Figure 8 As shown, the tube is first placed between the fixed moving frame 3 and the sliding moving frame 4. It should be noted that both the fixed moving frame 3 and the sliding moving frame 4 are equipped with a clamping tailstock. The two ends of the tube can be supported by the clamping tailstock. In addition, the fixed moving frame 3 and the sliding moving frame 4 are integrated with a motor, a reducer and a drive chuck, which can drive the tube to rotate around its own axis.

[0022] If it is necessary to replace or process a core of a different length or size, such as Figure 2 and Figure 3As shown, the sliding frame 4 can be moved closer to or away from the fixed frame 3 by the side sliding assembly and the translation drive assembly, thereby adjusting it to a position where the tube core can be placed. The side sliding assembly includes side pulleys 6 and side sliding frame 7. There are four side pulleys 6, and all four side pulleys 6 are in contact with the top of the placement frame 1. The side sliding frame 7 is fixedly installed on the top of the four side pulleys 6. The sliding frame 4 is fixedly connected to the side sliding frame 7. The translation drive assembly includes a support cover 8, a reciprocating screw 9 and a motor 11. The support cover 8 is fixedly installed on the side of both the placement frame 1 and the placement plate 2. The reciprocating screw 9 is rotatably installed inside the support cover 8, and a matching slider 10 is installed on the reciprocating screw 9. The motor 11 is installed on the side of the support cover 8, and the output end of the motor 11 is coaxially fixedly connected to the reciprocating screw 9. The two sliders 10 on the two reciprocating screws 9 are fixedly connected to the side of the sliding frame 4 and the sliding seat 23, respectively.

[0023] Specifically, during adjustment, the motor 11 is started, and the output end of the motor 11 drives the reciprocating screw 9 to rotate within the support cover 8. This causes the slider 10 on the reciprocating screw 9 to move the sliding frame 4. The bottom end of the sliding frame 4 can move via the side slide 7 and the side pulley 6, thus moving it closer to or away from the fixed frame 3. It should be noted that the shape design of the slider 10 matches the helical groove of the reciprocating screw 9. When the reciprocating screw 9 rotates, the side wall of the helical groove will generate an axial thrust on the slider 10 embedded therein. The slider 10 can move along the axial trajectory of the reciprocating screw 9, thus moving left and right. When the slider 10 reaches the end of the reciprocating screw 9, the output end of the motor 11 is started in the opposite direction, and the slider 10 will smoothly transition to the reverse helical groove, thus realizing reciprocating movement. This is a well-known technology and will not be elaborated further. In addition, a telescopic protective cover is installed inside the support cover 8, and the reciprocating screw 9 is located inside the telescopic protective cover, thus protecting the reciprocating screw 9.

[0024] After adjustment, the core tube is placed between the fixed moving frame 3 and the sliding moving frame 4. Since the sliding seat 23 is slidably mounted on the placement plate 2 through the rotating ring and is rotatably mounted on the rotating ring, and three air shafts 5 are rotatably mounted on the side of the sliding seat 23, and the sliding seat 23 is located on the side of the placement frame 1, different materials can be fitted onto the air shafts 5. Then, compressed air is injected into the air nozzle at the shaft end, and the rubber air bladder inside the shaft expands evenly, squeezing outward the aluminum key strip embedded in the keyway of the shaft body, so that the key strip extends outward radially until the top of the key strip is tightly attached to the material roll.

[0025] The material is then drawn out from the air shaft 5, passes through the guide roller, tension roller, and guide roller, and is introduced into the pressure roller component of the tube core. It is then wound onto the tube core in the process sequence, and the tube core is driven to rotate. The material is continuously pulled out as the tube core rotates and is tightly adhered to the surface of the tube core under the pressure of the pressure roller. The material is wrapped around the tube core layer by layer in a spiral stacking manner. It should also be noted that a storage rack for storing spiral steel wire is installed on the side of the placement frame 1. When the spiral steel wire needs to be wound, it is conveyed outward through the guide structure of the storage rack, and the storage rack can adjust the angle and position of the spiral steel wire according to the winding situation.

[0026] Furthermore, during the wrapping process, the motor 11 can be restarted, thereby moving the sliding seat 23 on the placement plate 2, which can evenly wrap the material around the core. During the wrapping of the core, the core can be supported by the anti-sinking support components, such as... Figure 4 , Figure 5 and Figure 6 As shown, the anti-sinking support assembly includes a mounting frame 12, electric push rods 13, a lifting frame 14, a left-right adjustment assembly, and a stabilizing assembly. The mounting frame 12 is fixedly mounted on the placement frame 1. Two sets of electric push rods 13 are provided, with two push rods in each set. Both sets of electric push rods 13 are mounted on the mounting frame 12. A lifting frame 14 is fixedly mounted on the output end of each set of electric push rods 13. The left-right adjustment assembly is mounted on the lifting frame 14. The stabilizing assembly is located on the side of the left-right adjustment assembly. The left-right adjustment assembly includes an adjustment cover 15, a sliding block 16, and a support roller 17. Two adjustment covers 15 are provided, each fixedly mounted on one of the two lifting frames 14. Two sliding blocks 16 are slidably installed on each side of the cover 15. Two support rollers 17 are provided, and a support roller 17 is rotatably installed between each pair of opposing sliding blocks 16. The stabilizing component includes a vertical slide rail 18, a stabilizing rod 19, a lower insertion rod 20, and a limiting component. Two vertical slide rails 18 are fixedly installed on the side of the adjusting cover 15. The stabilizing rod 19 is slidably installed on the side of the two vertical slide rails 18. The lower insertion rod 20 is fixedly installed on the side of the sliding block 16. The limiting component is provided on the side of the vertical slide rail 18. The limiting component includes a limiting plate 21 and a limiting post 22. The limiting plate 21 is fixedly installed on the side of the vertical slide rail 18, and the limiting post 22 is slidably installed through the side of the limiting plate 21.

[0027] Specifically, during winding, the electric push rod 13 is activated. The output end of the electric push rod 13 drives the two lifting frames 14 to move upward. The lifting frames 14 then drive the adjusting cover 15 to move upward. The adjusting cover 15 simultaneously drives the sliding block 16 to move upward, thereby causing the two support rollers 17 to move upward and fit against the tube core for support. Since the two support rollers 17 are rotatably mounted on the sliding block 16, they can also rotate with the rotation of the tube core during support, thus ensuring that the rotation of the tube core is not affected during support.

[0028] Furthermore, if the diameter of the core blank is relatively long, the sliding block 16 on the side of the adjusting cover 15 can slide on the side of the adjusting cover 15, thereby moving the two supporting rollers 17 in opposite or relative directions. During movement, because the stabilizing rod 19 has several slots that match the bottom end of the lower insertion rod 20, and both sides of the stabilizing rod 19 have slots that match the side of the limiting post 22, when the limiting post 22 and the slot are at the same horizontal position, the bottom end of the lower insertion rod 20 is inserted into the slot of the stabilizing rod 19, which can slide the limiting post 22 to the side, causing it to disengage from the side of the stabilizing rod 19. The lower insertion rod 20 is inserted into the slot on the surface, and then slides downward in the vertical slide rail 18 via the stabilizing rod 19, so that the bottom end of the lower insertion rod 20 disengages from the top slot of the stabilizing rod 19. At this time, the sliding block 16 will not be blocked when it is moved. After the adjustment is completed, the stabilizing rod 19 is moved upward, and the bottom end of the lower insertion rod 20 is inserted into the corresponding top slot of the stabilizing rod 19. At this time, the side of the limiting post 22 can be slid sideways, and the side of the limiting post 22 is inserted into the side slot of the limiting plate 21 and the stabilizing rod 19, thereby fixing the stabilizing rod 19. At this time, the sliding block 16 is limited, and the adjusted support roller 17 is also fixed.

[0029] Working principle: When processing the hose, first adjust the distance between the fixed moving frame 3 and the sliding moving frame 4 according to the core to be processed. Start the motor 11. The output end of the motor 11 drives the reciprocating screw 9 to rotate inside the support cover 8, thereby causing the slider 10 on the reciprocating screw 9 to move the sliding moving frame 4. The bottom end of the sliding moving frame 4 can move through the side slide 7 and the side pulley 6, thereby moving closer to or away from the fixed moving frame 3.

[0030] After adjustment, the material rolls on multiple air expansion shafts 5 are wound around the tube core. Then, the electric push rod 13 is started. The output end of the electric push rod 13 drives the two lifting frames 14 to move upward. The lifting frames 14 drive the adjusting cover 15 to move upward. The adjusting cover 15 simultaneously drives the sliding block 16 to move upward, thereby causing the two supporting rollers 17 to move upward and fit against the tube core for support. After completion, the tube core is driven to rotate, so that the material rolls on multiple air expansion shafts 5 successively wrap around the tube core, finally forming a floating hose.

[0031] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
