Abstract
Description
Technical Field
[0001] The invention relates to the technical field of preparation of a pipe and cable anti-bending device, and in particular to a casting mold, a production device and a production process, and a casting mold for a pipe and cable anti-bending device. Background Art
[0002] Marine cable bend preventers are key equipment for connecting offshore buoys or submarine wellheads, and are known as the "blood vessels" of marine floating production systems. During service, due to the effects of wind, waves, currents, and the movement of the buoy, the connection parts between the riser, dynamic cable, and the buoy will be deformed too much and cause structural failure. Therefore, cable bend preventers are of great significance in preventing risers and dynamic cables from failing due to excessive bending, and improving the structural safety of risers and dynamic cables.
[0003] The anti-bending device has the advantages of easy installation and small space requirements. It is the most widely used anti-bending equipment for risers and dynamic cables. It increases the local stiffness of the riser and dynamic cable so that it will not bend excessively when subjected to bending loads. The advantage of this anti-bending principle is that it can effectively suppress fatigue damage to the riser and dynamic cable. Therefore, the anti-bending device is the most widely used. Almost every riser or dynamic cable in dynamic applications needs to be installed with an anti-bending device on its top to protect it from bending damage under the action of severe wind, waves and currents, and to ensure long-term service.
[0004] At present, the design and manufacturing capabilities of large-scale pipe and cable bend limiters in China are still blank; the bend limiter has a conical shape and is molded in one piece by polyurethane casting, with a metal insert embedded at its tail to improve the overall bending moment strength. Conventionally, the bend limiter casting mold adopts a segmented structure with a ring-to-ring structure, such as the self-heating pipe and cable bend limiter casting mold structure proposed in patent No. 202420525366X; the above mold has at least the following problems during use:
[0005] 1. With the increase of the pouring amount of polyurethane for the anti-bending device, the pouring flow of the pouring machine is no longer sufficient, and because the pouring position is at the annular opening position at the top of the mold, the space is limited and can only be poured by one pouring machine. As a result, the polyurethane cannot be fully poured and filled within the curing time, and the preparation quality is greatly reduced.
[0006] 2. Before using the segmented mold, all the molds need to be assembled and then preheated. After preheating, the upper multi-segment mold needs to be dismantled. After one pouring is completed, it is necessary to wait for the installation of the upper mold. After the installation is completed, it can be poured again, which greatly prolongs the preparation time, reduces efficiency, and reduces quality. Of course, there are also those that are poured without disassembly, but when the size is large, the polyurethane pouring surface is too high, and the falling flow rate of the polyurethane is too fast during pouring, resulting in internal cavities or pores. Summary of the invention

[0017] A production process of a pipe and cable anti-bending device, using the above-mentioned production device, comprises the following steps:
[0018] Step 1, install the casting mold; fix the flip bracket on the track, connect the first end plate to the flip shaft seat, then flip the first end plate to a 90° vertical state, insert the first cylindrical section of the cylindrical inner mold into the first end plate and fix it, and pre-install the tie rod, then flip the first end plate to a horizontal state and fix it through a vertical fixing frame, and then assemble and fix the second cylindrical section of the cylindrical inner mold, the cylindrical outer mold, the conical outer mold and the second end plate in sequence;

[0027] Beneficial effects of the present invention:
[0028] 1. The casting method of the anti-bending device has been changed: the conventional vertical placement and top casting have been changed to horizontal placement casting, which avoids the internal cavity or air hole caused by the polyurethane casting surface being too high and the falling flow rate of polyurethane being too fast during casting; and the casting can be completed in one time without disassembling the mold, saving time and effort.

[0042] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0043] Reference Figures 1 to 7 As shown, an embodiment of the casting mold for the pipe and cable anti-bending device of the present invention includes a flip bracket 1 and a mold body 2, the flip bracket is provided with a flip shaft seat 3, a horizontal adjustment bracket 4 and a vertical fixing frame 5, the mold body is rotatably connected with the flip shaft seat, the flip shaft seat and the horizontal adjustment bracket cooperate to support the mold body in the horizontal direction, the flip shaft seat and the vertical fixing frame cooperate to fix the mold body in the vertical direction, the mold body includes a first end plate 6, a cylindrical outer mold 7, a conical outer mold 8 and a second end plate 9 connected in sequence, the conical outer mold has a C-shaped cross-section and the C-shaped opening is a pouring port 10, a cylindrical inner mold 11 is provided in the conical outer mold, and both ends of the cylindrical inner mold are respectively connected to the first end plate and the second end plate.
[0044] When in use, the mold body is flipped with the flip shaft seat as the flip fulcrum. When it needs to be assembled, the flip shaft seat and the vertical fixing frame are matched to achieve vertical fixation, so that the cylindrical outer mold, the second end plate of the conical outer mold and the cylindrical inner mold can be conveniently hoisted and fixed in sequence in the vertical direction (there are problems such as low docking accuracy and inconvenient screw locking in the horizontal direction). After the assembly is completed, the mold body is flipped to a horizontal position and supported by a horizontal adjustment bracket. At this time, the pouring port is facing upward and is located at the highest point. After preheating and other processes, polyurethane is poured, and the polyurethane flows into the mold body at the highest point. Because it is placed horizontally, the polyurethane falls at a small height, and the polyurethane can fill the internal space of the mold in a short time, which can solve the problems of cavity and pores. After heating and preliminary curing, the conical outer mold can be disassembled, and the pouring port is used as a breakthrough point to open it, so that the conical outer mold is deformed to be able to better separate from the cured polyurethane, and the conical outer mold can be quickly removed. After removal, most of the cured polyurethane is exposed to the outside, and then it can be pulled out from the cylindrical outer mold. Finally, vulcanization and surface finishing are performed to obtain the finished product.
[0045] Among them, the first end plate, the cylindrical outer mold, the conical outer mold and the second end plate cooperate to form an outer mold structure, and the cylindrical inner mold is set in the outer mold through the length to form a cavity with an annular cross-section, and the anti-bending device is prepared by pouring polyurethane. The mold body is assembled with multiple sections. During assembly, it can be connected and fixed in a vertical installation manner, which is convenient for lifting and assembly, and the difficulty of docking is explained.
[0046] When pouring is required, the mold body can be turned over and supported horizontally by the horizontal adjustment bracket. At this time, the pouring port of the conical outer mold faces upward. Figure 2 As shown, the horizontal adjustment bracket can be adjusted to arrange the pouring port horizontally, and is also at the highest position after the horizontal arrangement. The pouring port can provide a longer pouring interval, and can be poured at multiple points simultaneously without affecting each other. Specifically, the horizontal adjustment bracket includes a sliding groove 16, and two wedge-shaped sliders 17 are symmetrically arranged in the sliding groove. An adjustment bolt 18 is arranged between the wedge-shaped slider and the side wall of the sliding direction of the sliding groove. The two wedge-shaped sliders cooperate to form a V-shaped support structure. By adjusting the top setting of the bolt, the support height of the V-shaped support structure can be changed. The rotation angle of the mold body can be adjusted in conjunction with the flip shaft seat to ensure the horizontal position of the pouring port.
[0047] Reference Figure 1 and Figure 4 As shown, the above-mentioned flip shaft seat includes two rotation limit seats 14, in which a rotation shaft 15 is arranged, and the rotation shaft is fixedly connected to the outer surface of the first end plate. The two rotation limit seats limit the axial position of the mold body along the rotation axis, and also limit the radial position, so that the mold body can only be flipped, that is, the rotation axis can only rotate.
[0048] When the mold body needs to be assembled, a vertical fixing frame is used to fix the corresponding position to prevent the rotation of the rotation limit seat. Specifically, the vertical fixing frame includes a vertically arranged fixing bolt 19, on which a lower limit nut 20 and an upper limit nut 21 are arranged. The lower limit nut and the upper limit nut cooperate to fix the U-shaped plug plate 22. The U-shaped plug plate is installed on the outer surface of the first end plate. The flipping position of the U-shaped plug plate is limited, so as to fix the position of the mold body. The lower limit nut and the upper limit nut cooperate to limit the U-shaped plug plate at both ends in the rotation direction, so that the vertical layout angle of the mold body is adjustable, and the operation is convenient and reliable.
[0049] For the connection of the multi-section structure on the mold body, the first end plate and the cylindrical outer mold, the cylindrical outer mold and the conical outer mold, and the conical outer mold and the second end plate are connected by flanges 23, and are all provided with sealing rings. A C-type intermediate flange 24 is provided on the outer surface of the conical outer mold. The flange connection can ensure that the multi-section structure arranged along the axial direction can be quickly connected and the structural strength is stable. The C-type intermediate flange can play a reinforcing role on the conical outer mold with a longer size. At the same time, the flange between the conical outer mold and the second end plate and the C-type intermediate flange are both provided with horizontal adjustment brackets on the corresponding flip brackets. By increasing the support nodes, the mold body deformation caused by the increase in weight after pouring is avoided. The flange also has high strength and the support does not deform. At the same time, since the conical outer mold is an open structure, it can be formed by the process of rolling the steel plate into a cone, which greatly reduces the mold processing cost. During the demoulding process, the pouring port can be slightly opened by hydraulic equipment, so that the inner circle of the conical outer mold is enlarged, which is convenient for demoulding. The point where the hydraulic equipment applies the force is located at the flange to avoid squeezing injuries to the conical body of the conical outer mold.
[0050] Reference Figures 5 to 7 As shown, the cylindrical inner mold includes a tie rod 25 and a first cylindrical section 26 and a second cylindrical section 27 which are plugged in. The first cylindrical section passes through the first end plate and is fixedly connected to the outer surface of the first end plate. A force-bearing sealing plate 28 is also provided at the end of the first cylindrical section. A through hole is provided in the middle of the force-bearing sealing plate. A tension plate 29 and a hanging plate 30 are respectively provided at both ends of the second cylindrical section. The hanging plate is located on one side of the second end plate. A hanging buckle 31 is installed on the hanging plate. The tie rod passes through the through hole and is threadedly connected to the tension plate.
[0051] In one embodiment, since heating is required during the pouring process, a heating pipe may be wound around the outer surface of the mold body or a heating blanket may be wrapped around the outer surface of the mold body to perform heating and curing heating, and the structure is simple.
[0052] In one embodiment, referring to Figure 8 and Fig. 9As shown, the present invention also provides a production device for a pipe and cable anti-bending device, in order to improve the automated production capacity and ensure the temperature uniformity in the casting mold after heating, a hot oven 32 is designed, a track 33 is arranged in the hot oven, one end of the track extends to the outside, the above-mentioned casting mold 111 is arranged on the track, and both sides of the track extending to the outside are provided with casting machines 34, providing multiple casting machines to simultaneously cast polyurethane at the pouring port, greatly improving the casting efficiency. When in use, if the casting mold needs to be heated, it can be pushed into the hot oven through the track, and after the heating is completed, the casting mold is pulled out to perform casting and other processes.
[0053] A track wheel 35 is provided at the bottom of the flip bracket of the above-mentioned casting mold, which is more convenient when pushing and pulling the casting mold. However, due to the coordinated movement of the wheels, the position of the casting mold cannot be effectively fixed. Therefore, a sliding limit column 36 is provided on the end of the track extending to the outside, and a fixer 37 is also provided on the track. The casting mold abuts against the sliding limit column to determine its moving position, and then the casting mold is fixed to the track by the fixer to ensure that the position of the pouring port is within the pouring range of the pouring machine during pouring. The fixer can be an inverted L-shaped plate, which is fixed on the track, and its top is set above the flip bracket and is provided with a tightening screw. The tightening screw is extended to press the flip bracket toward the track, thereby limiting its movement and achieving the purpose of fixation.
[0054] In one embodiment, the present invention also discloses a production process of a pipe and cable anti-bending device, which adopts the above-mentioned production device. Specifically, the casting mold is first installed; the flip bracket is placed and fixed on the track to prevent it from sliding, and then the first end plate is connected to the flip shaft seat shaft, and then the first end plate is flipped to a 90° vertical state, the first cylindrical section of the cylindrical inner mold is inserted into the first end plate and fixed, and the pull rod is pre-installed, and then the first end plate is flipped to a horizontal state and fixed to the vertical fixing frame through the U-shaped plug plate on the first end plate. At this time, the first end plate is fixed and cannot be flipped, and then the second cylindrical section of the cylindrical inner mold is plugged into the first cylindrical section, and the plugging process is carried out by gently tapping with a hammer, and the two are locked together by the pull rod, and then the cylindrical outer mold, the conical outer mold and the second end plate can be successively sleeved on the outer periphery of the cylindrical inner mold for assembly and fixation; during the installation process, a sealing ring needs to be provided to ensure that the connecting parts do not leak.
[0055] Among them, in some designs of anti-bending devices, it is necessary to embed a metal insert 112. The metal insert is placed from top to bottom on the first end plate before installing the second cylindrical section. The screw portion of the metal insert passes through the first end plate and is locked and fixed.
[0056] After the assembly is completed, the mold body needs to be flipped over to meet the casting needs. The lifting buckle on the cylindrical inner mold is pulled by the lifting equipment. The lifting buckle is located at the end of the cylindrical inner mold on the side of the second end plate. After lifting, it forms a two-point support structure with the flip shaft seat. Before the flipping action, the mold body is fixed by the vertical fixing frame. The mold body is slowly lifted by the lifting equipment until it contacts the horizontal adjustment bracket. The level ruler is placed on the pouring port of the conical outer mold, and the horizontal state of the mold body is checked and adjusted by the horizontal adjustment bracket until the pouring port of the mold body is placed horizontally.
[0057] After the preparation work is completed, preheating is performed first, the flip bracket is fixed to the track, and the flip bracket and the mold body are pushed into the hot oven for heating;
[0058] After heating is completed, it is pushed out of the hot oven and moved to the pouring station by multiple pouring machines. At the same time, pouring is carried out through the pouring gate until the polyurethane pouring surface reaches the pouring gate. Multiple pouring machines pour at the same time, which greatly shortens the pouring time; the pouring gate provides the possibility of multiple pouring machines pouring at the same time.
[0059] After pouring, slowly push the flip bracket and the mold body into the hot oven to avoid excessive shaking that may cause the polyurethane to spill out, and heat it again in the hot oven to initially cure the polyurethane;
[0060] After the initial curing is completed, the hot oven is pushed out and the flip bracket is fixed on the track; the mold body is slowly lifted to a vertical state by the lifting equipment. The horizontal direction is not conducive to demolding, and the mold body is disassembled in the reverse order of the mold installation sequence, wherein the first cylindrical section and the first end plate are not disassembled; when a metal insert is provided, the connection between the metal insert and the first end plate needs to be released; the initially cured anti-bending device is clamped with a clamp, and slowly lifted until the anti-bending device is separated from the first end plate and the cylindrical outer mold, and then the vulcanization operation is performed until the design strength is reached;
[0061] After the lifting is completed, the dismantled parts can be assembled on the undisassembled first cylindrical section and the first end plate to prepare the next anti-bending device, which greatly improves the production efficiency.
[0062] Finally, the post-vulcanized anti-bending device is placed in the air to slowly cool to room temperature, and the raised portion of the casting surface of the anti-bending device is polished with a tool to obtain a finished anti-bending device.
[0063] The present invention utilizes the structural form of the anti-bending device and uses the conical outer mold as a breakthrough point. The pouring port at the small end of the conical outer mold is changed to a through-type long strip pouring port extending along the conical surface, which can effectively ensure that multiple pouring machines pour polyurethane at the same time, thereby improving efficiency. The posture of the mold body can be changed during the mold assembly and pouring process to meet the different needs of assembly and pouring, with high adaptability, greatly improving production efficiency and quality.
[0064] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or change made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
