Description

Technical Field

[0001] This application relates to the field of heating coil manufacturing technology, and in particular to a tooling for heating coils. Background Technology

[0002] In oil tankers, cargo holds serve to store cargo. To facilitate the transport of various liquid cargoes and prevent chemical reactions between different liquids, adjacent cargo holds are typically separated by tank-shaped bulkheads. Furthermore, to ensure optimal storage and transport conditions for the liquid cargoes, heating coils are installed on these bulkheads to heat the cargo. The height of these bulkheads on ships is usually quite high, making the installation of heating coils challenging.

[0003] The current installation method is as follows: after the trough-shaped bulkhead is welded, scaffolding is erected near the bulkhead, and then the heating coils are welded one by one to the bulkhead and fixed with flat steel brackets. However, the above method has the following main drawbacks: 1. During the splicing process of two adjacent heating coils, the welding accuracy is not easy to control; 2. The heating coils are too long and are prone to bending and collision during hoisting; 3. Erecting scaffolding more than ten meters high to install a few heating coils is costly and inefficient.

[0022] The following is in conjunction with the appendix Figure 1-11 Tooling 100 for heating coils is described in some embodiments of this application.

[0023] like Figure 1 As shown, the tooling 100 for heating coils according to an embodiment of the present invention includes: a first bracket 11, a second bracket 12, a lifting bracket 13, and a pedal 50.

[0024] The second bracket 12 is slidably engaged with the first bracket 11; and both the first bracket 11 and the second bracket 12 are provided with clamping components 20. The hoisting bracket 13 is connected to the first bracket 11 and / or the second bracket 12, and the hoisting bracket 13 is used to engage with the trough-shaped bulkhead 200; wherein the first bracket 11 and / or the second bracket 12 are provided with pedals 50.

[0025] In practical use, such as Figure 2 As shown, the two heating coils 400 can be fixed on the first bracket 11 and the second bracket 12 respectively by the clamping assembly 20. Then, the distance between the first bracket 11 and the second bracket 12 can be adjusted by sliding the second bracket 12 to align the mating ends of the two heating coils 400, thereby ensuring the mating accuracy of the heating coils 400 during splicing. Then, the mating joint of the two heating coils 400 is welded, as shown at the weld joint 900.

[0026] like Figure 3As shown, the trough-shaped bulkhead 200 is installed on the ship deck 300. The lifting bracket 13 can be directly clamped and fixed to the top of the trough-shaped bulkhead 200 by a crane. Due to the fixing of the heating coil 400 by the first bracket 11 and the second bracket 12, the heating coil 400 can be supported and protected during transportation, reducing the risk of bending and collision of the heating coil 400 during hoisting and splicing. Then, the construction personnel can stand on the footboard 50 to complete the welding operation of splicing the heating coil 400 and the trough-shaped bulkhead 200. That is, the tooling 100 for heating coils in this application can be used to assist in the welding of the heating coil 400 and also for the installation of the heating coil 400 and the trough-shaped bulkhead 200, so that no additional scaffolding is needed, which effectively reduces the construction cost and improves the installation efficiency of the heating coil 400.

[0027] According to an embodiment of the present invention, the tooling 100 for heating coils can adjust the distance between the first bracket 11 and the second bracket 12 according to the length of the heating coil 400 through the sliding cooperation of the first bracket 11 and the second bracket 12, adapting to the installation requirements of heating coils 400 of different specifications; the clamping assembly 20 can reliably clamp and fix the heating coil 400; after the hoisting bracket 13 is snapped into the trough-shaped bulkhead 200, it can drive the entire tooling and the clamped and fixed heating coil 400 to move and adjust its position along the trough-shaped bulkhead 200, without the need for additional scaffolding. The operators can also stand on the footplate 50 to cooperate in completing the installation and welding operations, which can effectively reduce the installation cost, improve the installation accuracy and efficiency of the heating coil 400, and at the same time avoid bending and collision of the heating coil 400 during hoisting and installation, thus improving the safety of the installation operation.

[0028] In some embodiments, such as Figure 4 As shown, the lifting bracket 13 may include a telescopic connector 131, an IMU attitude detection sensor 132, a lifting attitude adjustment motor 133, a lifting lug 134, and a lifting slot 135. One end of the telescopic connector 131 is connected to the first bracket 11, and the other end is connected to the lifting slot 135. The lifting slot 135 is used to engage with the trough-shaped bulkhead 200. The telescopic connector 131 is used to drive the first bracket 11 to move radially along the heating coil 400 relative to the lifting slot 135, so as to install the tooling 100 onto the trough-shaped bulkhead 200. At 00:00, the distance between the first bracket 11 and the trough-shaped bulkhead 200 is adjusted. The lifting lug 134 is installed in the lifting slot 135 and is used to cooperate with the crane. The IMU attitude detection sensor 132 and the lifting attitude adjustment motor 133 are both installed on the lifting slot 135. The IMU attitude detection sensor 132 is used to continuously acquire the attitude information of the tooling 100 during the installation of the tooling 100 to the trough-shaped bulkhead 200, and control the lifting attitude adjustment motor 133 to drive the telescopic connector 131 to move according to the attitude information.

[0029] In this way, during the process of the crane lifting the fixture 100 and the heating coil 400 to the installation position of the trough-shaped bulkhead 200, the IMU attitude detection sensor 132 can monitor the tilt angle and overall attitude of the fixture 200 in real time. When the fixture 100 deviates in attitude due to the shaking during lifting, the lifting attitude adjustment motor 133 can be controlled in time to adjust the extension and retraction of the telescopic connector 131, quickly correct the attitude of the fixture 100, ensure that the heating coil 400 is aligned with the preset installation position, improve the efficiency and accuracy of lifting alignment, and reduce the workload of manual alignment adjustment.

[0030] In some embodiments, the first bracket 11 and / or the second bracket 12 are provided with mounting grooves 14, and the pedal 50 is adapted to engage with the mounting grooves 14. This facilitates reducing the difficulty of connecting the pedal 50 to the first bracket 11 and / or the second bracket 12, and also facilitates the disassembly of the pedal 50 from the first bracket 11 and / or the second bracket 12.

[0031] In some embodiments, such as Figure 5 As shown, the first bracket 11 and / or the second bracket 12 are provided with flat steel brackets 15. One end of the flat steel bracket 15 is used to support the heating coil 400 and the other end is used to abut against the trough-shaped bulkhead 200, so as to enhance the stability of the heating coil 400 during the installation process through the flat steel bracket 15.

[0032] In some embodiments, such as Figure 5 As shown, the tooling 100 also includes: a lifting assembly 60, a hoisting bracket 13 disposed on the first bracket 11, and the lifting assembly 60 disposed on the second bracket 12 at the end away from the hoisting bracket 13.

[0033] In this way, the lifting assembly can provide support from below for the second bracket 12 and the heating coil 400 held by the second bracket 12. With the hoisting and fixing of the hoisting bracket 13, the fixture 100 is more stably fixed on the trough-shaped bulkhead 200, avoiding the fixture 100 from drooping and swaying at the end due to its excessive length. This further improves the structural stability during the installation process, ensures the docking accuracy of the heating coil 400, and enhances the safety of the operation.

[0034] In some embodiments, such as Figure 6 As shown, the tooling 100 also includes a butt welding auxiliary module 80, which is installed on the first bracket 11 and / or the second bracket 12. The butt welding auxiliary module 80 is used to snap the heating coil 400 and to drive the heating coil 400 to rise or fall.

[0035] This makes it easier to adjust the height of the heating coil 400, so that the two heating coils 400 can be connected more precisely, thereby improving the welding accuracy.

[0036] In some embodiments, the first support 11 and / or the second support 12 are provided with a plurality of clamping assemblies 20, which are arranged radially spaced along the heating coil.

[0037] The first bracket 11 and / or the second bracket 12 may be provided with a grooved support plate 70 (e.g., ...). Figure 7 The grooved support plate 70 shown in the figure, as Figure 8 As shown, the grooved support plate 70 is provided with a rack 78, and a hinge 77 can be installed on the grooved support plate 70 and is used for guiding and engaging with the clamping assembly 20. Two adjacent clamping assemblies 20 are hinged together by a first pitch-changing support rod 71 and a second pitch-changing support rod 72. The first pitch-changing support rod 71 and the second pitch-changing support rod 72 are hinged together. The pitch-changing drive base 74 is installed on the grooved support plate 70, and the pitch-changing drive base 74 is provided with a pitch-changing drive motor 75. The output shaft of the pitch-changing drive motor 75 is provided with a pitch-changing drive tooth 76, which meshes with the rack.

[0038] It is understandable that the output shaft of the variable pitch drive motor 75 drives the variable pitch drive gear 76 to rotate along the rack 78, thereby pushing the hinge 77 to slide relative to the groove support plate 70. At this time, the included angle between the first variable pitch support rod 71 and the second variable pitch support rod 72 increases or decreases, so that the distance between two adjacent clamping components 20 increases or decreases, thereby realizing the adjustment of the distance between two adjacent clamping components 20.

[0039] In some embodiments, such as Figure 8 As shown, the clamping assembly 20 includes: a rotary motor 21, which is mounted on a first bracket 11 and / or a second bracket 12; a deformable element, which is mounted on the output shaft of the rotary motor 21 and is configured to extend or retract radially in the output shaft of the rotary motor 21; and a heating coil 400 adapted to be fitted onto the deformable element.

[0040] Understandably, during use, the end of the heating coil 400 to be assembled is first inserted onto the outside of the deformable component. When the deformable component extends radially outward from the output shaft of the rotary motor 21, it can tighten and fix the heating coil 400 from inside. When it retracts, the fixing of the heating coil 400 is released. The assembly and disassembly operations are convenient, and the structure is simple and reliable. The rotary motor 21 can also drive the heating coil 400 to rotate, adjusting the welding orientation of the heating coil 400, making it convenient for operators to complete the assembly and welding work without repeatedly adjusting the tooling position, further improving work efficiency.

[0041] In some embodiments, such as Figure 1 As shown, the tooling 100 for heating the coil also includes a welding robotic arm, which is movably mounted on the first bracket 11 and / or the second bracket 12.

[0042] Understandably, the welding robotic arm can automatically complete the welding work at the splice of the heating coil 400 after the tooling is adjusted into place, without the need for close-range manual operation, thus reducing the labor intensity of manual welding. At the same time, it can ensure a stable and uniform welding trajectory, effectively improving the welding quality of the splice weld of the heating coil 400. It can also adapt to the welding requirements of different docking positions, further improving the automation level of the installation of the heating coil 400 and increasing the efficiency of the installation operation.

[0043] In some embodiments, the clamping assembly 20 further includes a push cylinder 22, which is mounted on the output shaft of the rotary motor 21 via a push base 23 and connected to the deformable member. The push cylinder 22 is configured to drive at least a portion of the deformable member to move axially along the output shaft so that the deformable member extends or retracts radially along the output shaft.

[0044] Understandably, the cylinder 22 provides a stable driving force, which triggers the radial expansion and contraction of the deformable parts through axial movement. The transmission path is simple, the control precision is high, and it can reliably achieve the clamping and fixing of heating coils 400 with different inner diameters, ensuring clamping stability.

[0045] In some embodiments, such as Figure 8 As shown, the output shaft of the rotary motor 21 is fixedly provided with a limiting member 25. The deformable member includes a first push rod 241 and a second push rod 242. The first push rod 241 is hinged to the piston 221 of the push cylinder, the second push rod 242 is hinged to the first push rod 241, and the second push rod 242 is hinged to the limiting member 25.

[0046] It is understandable that when the cylinder 22 drives the first push rod 241 to move axially, it will cause the hinge position of the first push rod 241 and the second push rod 242 to move, thereby changing the overall radial dimension of the first push rod 241 and the second push rod 242, realizing the extension and tightening and retraction and loosening. The structure is simple, the transmission is stable, and the processing and manufacturing cost is low.

[0047] In some embodiments, such as Figure 8 As shown, a tensioning wheel 27 is provided at the hinge of the first push rod 241 and the second push rod 242. The tensioning wheel 27 is located on the side of the hinge of the first push rod 241 and the second push rod 242 away from the output shaft.

[0048] In some implementations, such as Figure 8 As shown, a friction airbag 28 is provided at the free end of the piston 221 of the cylinder. The friction airbag 28 is adapted to be inflated to abut against the inner wall of the heating coil 400, thereby increasing the friction between the clamping assembly 20 and the heating coil 400 when the heating coil 400 rotates, and ensuring the rotational stability of the heating coil 400.

[0049] Understandably, when the deformable component expands, the tensioning wheel 27 directly abuts against the inner wall of the heating coil 400, increasing the contact area between the deformable component and the inner wall of the heating coil 400, improving clamping friction, and further ensuring the reliability of clamping and fixing, while preventing the hard rod end from directly scratching the inner wall of the heating coil 400. Simultaneously, the tensioning wheel 27 makes rolling contact with the inner wall of the heating coil 400. When the rotary motor 21 drives the heating coil 400 to rotate and adjust its position, the tensioning wheel 27 can assist in the rotation, preventing jamming and further improving the smoothness of the rotation and adjustment of the heating coil 400.

[0050] In some embodiments, such as Figure 1 As shown, the tooling 100 also includes a height adjustment component 40. One end of the height adjustment component 40 is connected to the side of the first support 11 and / or the second support 12 away from the pedal 50. The height adjustment component 40 is used to abut against the trough-shaped bulkhead 200. It can be understood that the height adjustment component 40 can support the entire tooling in close contact with the surface of the trough-shaped bulkhead 200, improve the stability of the tooling after installation, prevent the hoisting support 13 from shaking due to excessive force, and improve the safety of the tooling and the operators during operation.

[0051] In some embodiments, such as Figure 11 As shown, the height adjustment assembly 40 includes an adjustment motor 401 and a support member. The adjustment motor 401 is mounted on the first bracket 11 and / or the second bracket 12, and the support member is mounted on the output shaft 402 of the adjustment motor. It can be understood that the adjustment motor 401 can drive the support member to rotate, adjusting the angle of the support member's extension to adapt to the contact requirements of different positions and shapes of the trough-shaped bulkhead 200, ensuring that the support member always reliably contacts the surface of the trough-shaped bulkhead 200, improving support stability, and adapting to different installation conditions.

[0052] In some embodiments, such as Figure 11 As shown, the height adjustment assembly 40 also includes an opening and closing motor 403, which is mounted on the output shaft of the adjustment motor 401. Two support members are provided, which are spaced apart along the axial direction of the output shaft of the adjustment motor 401. The output shaft of the opening and closing motor 403 is provided with a drive gear 404, and both support members are provided with arc-shaped racks 405. The two arc-shaped racks 405 are symmetrically arranged on both sides of the drive gear 404 and mesh with the drive gear 404.

[0053] Understandably, after the opening and closing motor 403 drives the drive gear 404 to rotate, it can synchronously drive the two support members to move in opposite directions through gear and rack meshing transmission, adjust the opening distance between the two support members, and thus adjust the extension length of the support members in the radial direction of the output shaft of the adjusting motor 401. This satisfies the different distances from the first bracket 11 and / or the second bracket 12 to the trough-shaped bulkhead. In this way, the support position and support range can be flexibly adjusted to adapt to the concave and convex structures of different trough-shaped bulkheads 200, ensuring that both support members can reliably abut against the surface of the trough-shaped bulkhead 200, and further improving the adaptability of the height adjustment component 40 to different working conditions.

[0054] In some embodiments, such as Figure 11 As shown, the support includes a support rod 406 and a mating wheel 407. The support rod 406 is connected to the output shaft of the adjusting motor 401, and the mating wheel 407 is rotatably mounted on the support rod 406. It is understood that when the fixture moves along the trough-shaped bulkhead 200 to adjust the installation position of the heating coil 400, the mating wheel 407 can roll along the surface of the trough-shaped bulkhead 200, reducing the resistance to the movement of the fixture, preventing the support from jamming or scraping against the trough-shaped bulkhead 200, and ensuring the smoothness of the fixture's position adjustment.

[0055] In some embodiments, such as Figure 11 As shown, the outer peripheral wall of the mating wheel 407 is provided with a groove, and a magnetic adsorption component 408 is provided in the groove. It can be understood that the magnetic adsorption component 408 can be adsorbed onto the surface of the steel trough-shaped bulkhead 200, further improving the stability of the tooling. The groove can be adapted to the protruding ribs of the trough-shaped bulkhead 200, improving the mating positioning accuracy, preventing the mating wheel 407 from slipping, and further improving the reliability of support positioning.

[0056] In some embodiments, such as Figure 10 As shown, the butt welding auxiliary module 80 includes a welding support base 81, a welding support wheel 82, a sliding support arm 83, a folding drive motor 84, and a welding height adjustment bracket 85.

[0057] Welding support base 81 is hinged to the first bracket 11 and / or the second bracket 12. Multiple welding support bases 81 are provided, and multiple welding support bases 81 correspond one-to-one with multiple clamping components 20 in the axial direction of the heating coil 400. Welding support wheels 82 are provided on the welding support base 81 for rolling engagement with the outer peripheral wall of the heating coil 400. Welding height adjustment bracket 85 is installed on the grooved support plate 70. One of two adjacent welding support bases 81 is hinged to the first pitch support rod 71, and the other is hinged to the second pitch support rod 72. The first pitch support rod 71 and the second pitch support rod 72 are hinged. Sliding support arm 83 is slidably installed on the welding height adjustment bracket 85 along the distribution direction of the welding support bases 81. Folding drive motor 84 is installed on the welding height adjustment bracket 85 and is used to drive the sliding support arm 83 to slide along the distribution direction of the welding support bases 81.

[0058] In this way, the sliding support arm 83 can be driven by the folding drive motor 84 to slide along the distribution direction of the welded support base 81, so that the included angle between the first variable pitch support rod 71 and the second variable pitch support rod 72 increases or decreases, so that the distance between two adjacent welded support bases 81 increases or decreases, thereby realizing the adjustment of the distance between two adjacent welded support bases 81.

[0059] The following is in conjunction with the appendix Figure 1-11 A specific embodiment of the tooling 100 for heating coils according to this application is described: First, the two heating coils 400 are butt-welded in the production workshop to meet the height requirements of the trough-shaped bulkhead 200. A crucial step in the butt welding process is ensuring precise alignment of the two heating coils 400. Before butt welding, the butt welding auxiliary module 80 is moved to the appropriate position, one end of the heating coil 400 is inserted into the clamping assembly 20, and the other end is placed on the welding support wheel 82. At this time, the electric cylinder 22 is activated, pushing the tensioning wheel 27 to clamp the inner wall of the heating coil 400, and the friction airbag 28 is activated to ensure that the heating coil 400 does not shift. Simultaneously, under the action of the welding height adjustment bracket 85, it can adapt to pipes of different diameters. By adjusting the height of one end of the heating coil 400, the horizontal position of the heating coil 400 is ensured. Under the action of the variable pitch drive motor 75, the spacing between the four adjacent heating coils 400 can be adjusted. After the spacing is adjusted, the variable pitch locking mechanism 73 works to ensure that the spacing does not change. Then, the distance between the first bracket 11 and the second bracket 12 is adjusted to fix the front and rear heating coils 400. During the welding process, the rotary motor 21 is started to drive the heating coils 400 to rotate, which facilitates continuous welding. After welding is completed, a butt weld is formed. At this time, the welding height adjustment bracket 85 is started to adjust the height to the lowest level. The folding drive motor 84 is started to retract the butt weld auxiliary module 80. After retraction, it is fixed on both sides of the second bracket 12 to avoid interference with the heating coils 400 during installation.

[0060] Next, install the flat steel bracket 15 and the pedal 50. After installation, the device is transported to the shipyard manufacturing area via the height adjustment assembly 40. The opening and closing motor 403 drives the arc rack 405 to move through gear meshing, thereby controlling the angle between two adjacent mating wheels 407 and adjusting the height above the ground. The smaller the included angle, the higher the height above the ground.

[0061] Then, upon arrival at the shipyard manufacturing area, the hoisting bracket 13 is installed, and the equipment is hoisted using a truck crane. The truck crane lifts the tooling 100 using the lifting lugs 134. During the hoisting process, the telescopic connector 131 can adjust the distance between the tooling 100 and the trough-shaped bulkhead 200. During the hoisting process, strong winds may cause the equipment to rotate and swing in the air. At this time, the IMU attitude detection sensor 132 can monitor the status of the equipment in real time, and then the hoisting attitude adjustment motor 133 is activated to control the attitude of the tooling 100 in the air, thereby ensuring that the tooling 100 is parallel to the trough-shaped bulkhead 200. During the hoisting process, the hoisting slot 135 is installed on the trough-shaped bulkhead 200.

[0062] Then, by adjusting the opening and closing motor 403, the tooling 100 and the trough-shaped bulkhead 200 are kept at a suitable distance, ensuring that the flat steel bracket 15 and the trough-shaped bulkhead 200 are tightly fitted, which is convenient for subsequent welding; the magnetic adsorption component 408 is activated to ensure that the trough-shaped bulkhead 200 is tightly adsorbed.

[0063] At this time, the flat steel bracket 15 can be welded and fixed by automatic welding or manual welding; the automatic welding method is carried out by welding robotic arm 30; the manual welding method is carried out by climbing board 50, and the board 50 can fix the safety belt during the welding process.

[0064] Finally, tooling 100 is removed, magnetic adsorption component 408 stops working, and friction airbag 28 stops working; the distance between the first support 11 and the second support 12 is adjusted; the truck crane is connected to the lifting lug 134 to start lifting, the opening and closing motor 403 is started, and the distance between the truck crane and the trough-shaped bulkhead 200 is increased; at this point, the four heating coils 400 and the two flat steel supports 15 are fixed to the trough-shaped bulkhead 200.

[0065] The tooling 100 for heating coils in this application has at least the following advantages compared to the prior art: 1. The tooling 100 for heating coils of the present invention has high flexibility and can be adapted to the auxiliary welding and installation of heating coils 400 with different diameters, lengths and spacings.

[0066] 2. This invention solves the problems of high difficulty in butt welding of heating coil 400, excessive length of heating coil 400 after butt welding, which makes it inconvenient to transport from the production workshop to the slipway; and the time-consuming and labor-intensive problem of installing heating coil 400 on the trough-shaped bulkhead 200.

[0067] 3. This invention innovates the installation method of the trough-shaped bulkhead 200 and the heating coil 400, improves the installation efficiency of the heating coil 400, shortens the shipyard construction cycle, and accelerates the production speed of oil tankers.
