Description

A marine pipeline welding fixture Technical Field

[0001] This utility model relates to the field of ship welding fixture technology, and in particular to a ship pipeline welding fixture. Background Technology

[0002] Ship piping systems play a crucial role in power transmission, fluid transport, and exhaust gas emission, and their performance directly impacts the safety and efficiency of the vessel. Therefore, extremely high welding quality is required, with welds needing high strength, excellent sealing, and fatigue resistance. Welding fixtures play an indispensable role in ship piping welding; they fix the pipes, reduce the difficulty of manual operation, improve welding efficiency, and alleviate the labor intensity of workers.

[0003] However, the existing clamps are fixed structures and cannot be adjusted according to the welding angle between the two pipe sections. Furthermore, the clamping position cannot be adjusted according to the length of the pipe during use, which can result in some longer pipes not being securely fixed.

[0004] Therefore, this utility model proposes a ship pipeline welding fixture to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a ship pipe welding fixture, which solves the problem that the existing fixtures are all fixed structures, cannot be adjusted according to the docking angle between two pipe sections, and are not convenient to dock the two pipe sections during use. Therefore, a ship pipe welding fixture is proposed.

[0006] The purpose of this utility model is achieved as follows:

[0007] A marine pipe welding fixture includes a base plate. Two rotating shafts are symmetrically and fixedly connected to the top of the base plate. A first mounting plate and a second mounting plate are rotatably mounted on the outer sides of the two rotating shafts, respectively. A first screw is threaded onto both the first and second mounting plates. Multiple first adjustment holes that cooperate with the first screws are opened on the top of the base plate. These holes are distributed around the outer sides of the rotating shafts. A first translation mechanism is mounted on the top of the first mounting plate, and a second translation mechanism is mounted on the top of the second mounting plate. Multiple first pipe fixing components are slidably mounted on the first translation mechanism, and multiple second pipe fixing components are slidably mounted on the second translation mechanism.

[0008] Furthermore, the top of the base plate is fixedly connected with multiple evenly distributed support legs, and the bottom of both the first mounting plate and the second mounting plate is equipped with multiple casters.

[0009] Furthermore, both the first translation mechanism and the second translation mechanism include a slide rail, on which a slider is slidably mounted, and a mounting base is fixedly mounted on the top of the slider.

[0010] Furthermore, both the first pipe fixing assembly and the second pipe fixing assembly include a first bracket and a second bracket symmetrically mounted on the top of the mounting base. A first support roller is rotatably mounted on the inner side of the first bracket, and a motor for driving the first support roller to rotate is mounted on the first bracket. A second support roller is rotatably mounted on the inner side of the second bracket.

[0011] Furthermore, the mounting base is provided with a plurality of evenly distributed second adjustment holes, and both the first bracket and the second bracket are threadedly connected with bolts that cooperate with the second adjustment holes.

[0012] Furthermore, a second screw that passes through the slider is threaded onto the mounting base.

[0013] Furthermore, a third bracket is installed on both the first bracket and the second bracket, and a cylinder is fixedly installed on the third bracket, with a pad installed on the moving end of the cylinder.

[0014] Compared with the prior art, this utility model provides a marine pipeline welding fixture, which has the following advantages:

[0015] (1) With the setting of the rotating shaft, the first screw and the first adjustment hole, the first mounting plate and the second mounting plate can be rotated and adjusted according to the docking angle of the pipes at both ends during use. After the angle of the first mounting plate and the second mounting plate is adjusted, the first screw can be screwed into the first adjustment hole at the corresponding position to fix the angle of the first mounting plate and the second mounting plate. It is more flexible and convenient to use and can facilitate the clamping of pipes with different welding angles.

[0016] (2) By setting up a first translation mechanism and a second translation mechanism, the present invention can adjust the position of multiple first pipe fixing components and multiple second pipe fixing components that are slidably installed on the pipe according to the length of the pipe during use, so as to avoid the situation that the long pipe is unstable due to uneven clamping points, and ensure that pipes of various lengths can be firmly fixed, thereby improving the versatility of the clamp.

[0024] To better understand the technical solution of this utility model, a detailed description will be provided below in conjunction with relevant illustrations. It should be understood that the specific embodiments described below are not intended to limit the specific implementation of the technical solution of this utility model, but are merely possible implementations of the technical solution of this utility model. It should be noted that the descriptions of the positional relationships of the components herein, such as component A being located above component B, are based on the relative positions of the components in the illustrations and are not intended to limit the actual positional relationships of the components. Example 1

[0025] Referring to Figures 1-5, Figure 1 shows a structural schematic diagram of a ship pipe welding fixture according to Embodiment 1. As shown in the figure, the ship pipe welding fixture according to Embodiment 1 includes a base plate 1. Two rotating shafts 9 are symmetrically provided on the top of the base plate 1 and fixedly connected thereto. A first mounting plate 2 and a second mounting plate 3 are rotatably mounted on the outer sides of the two rotating shafts 9, respectively. A first screw 10 is threadedly connected to both the first mounting plate 2 and the second mounting plate 3. A plurality of first adjustment holes 12 are provided on the top of the base plate 1 to cooperate with the first screw 10. The plurality of first adjustment holes 12 are distributed around the outer side of the rotating shafts 9.

[0026] A first translation mechanism 5 is installed on the top of the first mounting plate 2, and a second translation mechanism 6 is installed on the top of the second mounting plate 3. Multiple first pipe fixing components 7 are slidably installed on the first translation mechanism 5, and multiple second pipe fixing components 8 are slidably installed on the second translation mechanism 6. Through the setting of the rotating shaft 9, the first screw 10, and the first adjusting hole 12, the first mounting plate 2 and the second mounting plate 3 can be rotated and adjusted according to the docking angle of the pipes at both ends during use. After the angle of the first mounting plate 2 and the second mounting plate 3 is adjusted, the first screw 10 is screwed into the first adjusting hole 12 at the corresponding position to fix the angle of the first mounting plate 2 and the second mounting plate 3. It is more flexible and convenient to use, and can easily clamp pipes with different welding angles. By setting the first translation mechanism 5 and the second translation mechanism 6, the position of the multiple first pipe fixing components 7 and the multiple second pipe fixing components 8 slidably installed on them can be adjusted according to the length of the pipe during use, avoiding the situation where long pipes are unstable due to uneven clamping points, ensuring that pipes of various lengths can be firmly fixed and improving the versatility of the clamp.

[0027] As shown in Figures 1 and 2, the top of the base plate 1 is fixedly connected with multiple evenly distributed support legs 4, and the bottom of both the first mounting plate 2 and the second mounting plate 3 is equipped with multiple casters 11. It should be noted that the support legs 4 provide support for the base plate 1, and the casters 11 make the first mounting plate 2 and the second mounting plate 3 rotate and adjust more smoothly.

[0028] As shown in Figures 1, 2, and 5, both the first translation mechanism 5 and the second translation mechanism 6 include a slide rail 501. A slider 502 is slidably mounted on the slide rail 501, and a mounting base 505 is fixedly mounted on the top of the slider 502. A second screw 503, threaded through the slider 502, is threaded onto the mounting base 505. It should be noted that during use, rotating the second screw 503 allows its bottom end to abut against the slide rail 501, thereby fixing the slider 502. It should also be noted that during use, the first pipe fixing component 7 and the second pipe fixing component 8 can slide on the slide rail 501 via the slider 502, thereby adjusting their positions. The mounting base 505 facilitates the installation of the first pipe fixing component 7 and the second pipe fixing component 8.

[0029] As shown in Figures 1, 2, and 5, both the first pipe fixing assembly 7 and the second pipe fixing assembly 8 include a first bracket 701 and a second bracket 702 symmetrically mounted on the top of the mounting base 505. A first support roller 703 is rotatably mounted on the inner side of the first bracket 701, and a motor 705 for driving the first support roller 703 to rotate is mounted on the first bracket 701. A second support roller 704 is rotatably mounted on the inner side of the second bracket 702. It should be noted that during use, the first support roller 703 and the second support roller 704 can lift the pipe, and the motor 705 can drive the first support roller 703 to rotate, thereby rotating the pipe between the first support roller 703 and the second support roller 704, facilitating the connection of the pipe structure by workers.

[0030] As shown in Figures 1, 2, and 5, the mounting base 505 has multiple evenly distributed second adjustment holes 504. Both the first bracket 701 and the second bracket 702 are threadedly connected to bolts 709 that mate with the second adjustment holes 504. It should be noted that the bolts 709 and the second adjustment holes 504 allow for adjustment of the positions of the first bracket 701 and the second bracket 702 on the mounting base 505 during use, facilitating the use with pipes of different diameters.

[0031] As shown in Figures 1, 2, and 5, a third bracket 706 is installed on both the first bracket 701 and the second bracket 702. A cylinder 707 is fixedly installed on the third bracket 706, and a pad 708 is installed on the moving end of the cylinder 707. It should be noted that the third bracket 706 facilitates the installation of the cylinder 707. In use, the two cylinders 707 can respectively drive the pad 708 on their moving ends to clamp and fix the pipe from both sides.

[0032] Working principle:

[0033] This utility model provides a marine pipeline welding fixture. In use: the first mounting plate 2 and the second mounting plate 3 are rotated according to the pipe docking angle. After the angle of the first mounting plate 2 and the second mounting plate 3 is adjusted, the first screw 10 is screwed into the corresponding first adjustment hole 12 to fix the first mounting plate 2 and the second mounting plate 3. Then, the positions of multiple first pipe fixing components 7 and multiple second pipe fixing components 8 are adjusted according to the length of the pipe so that the multiple first pipe fixing components 7 and multiple second pipe fixing components 8 can evenly clamp and fix the pipe. After adjustment, the pipe is hoisted between the first support roller 703 and the second support roller 704. Then, the cylinder 707 drives the pad 708 to clamp the pipe from both sides. At this time, pushing the mounting seat 505 can make the clamped pipe slide on the slide rail 501 through the slider 502, which facilitates the docking of the two pipe sections at the interface. After the pipes are docked together at the interface, the welding operation can be performed.

[0034] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
