Description

Technical Field

[0001] The present application relates to the field of shipbuilding, and in particular to a pipe auxiliary installation device. Background Art

[0002] In shipbuilding, hull pipe fittings are mostly assembled by welding, which places high demands on the positioning time, support strength and positioning accuracy of the pipe fittings.

[0003] In the past, brackets were typically welded onto the segmented shell to initially locate the installation position, then the installation angle was adjusted. After checking for positioning accuracy, brackets were then welded around the pipe fittings to secure them, and finally, the installation process was completed by welding. While this traditional assembly process is simple to operate and ensures positioning strength, welding horse feet directly onto the pipe fittings and segmented shells only secures the pipe fittings and cannot adjust the installation positioning angle. Furthermore, this welding method negatively impacts the material quality of the segments and pipe fittings. Furthermore, the removal and grinding of the horse feet after installation increases the time required. Summary of the Invention

[0029] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are 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.

[0030] See also Figures 1 to 4 The embodiment of the present application provides a pipe auxiliary installation device, which can solve the problem in the related art that the pipe installation positioning angle cannot be adjusted during pipe welding and the operation efficiency is low.

[0031] An embodiment of the present application provides a pipe auxiliary installation device, which includes: a second connecting component 2 and a first connecting component 1, a segmented shell plate fixing part 21 is provided at one end of the second connecting component 2, and a connection point is provided on the second connecting component 2; a pipe fixing part 12 is provided at one end of the first connecting component 1, and the first connecting component 1 is movably connected to the connection point. The first connecting component 1 can move along the length direction of the second connecting component 2, and can also rotate around the connection point to make the pipe fixing part 12 approach or move away from the segmented shell plate fixing part 21.

[0032] The present application is connected to the segmented shell plate 4 through the segmented shell plate fixing member 21, and is connected to the pipe fitting 5 through the pipe fitting fixing member 12, and uses the first connecting component 1 and the second connecting component 2 to support the pipe fitting 5 and the segmented shell plate 4. This not only avoids the situation where a large number of flaws are welded on the segmented shell plate 4 and the pipe fitting 5, but also when the first connecting component 1 moves along the length direction of the second connecting component 2, the height of the pipe fitting 5 relative to the segmented shell plate 4 can be adjusted. When the first connecting component 1 rotates around the connection point, the angle of the pipe fitting 5 relative to the segmented shell plate 4 can be adjusted, thereby improving the assembly quality of the segmented shell plate 4 and the pipe fitting 5.

[0033] It should be noted that the term "can" here means "can" or "capable of." This means that the first connecting component 1 can move along the length of the second connecting component 2 and rotate about the connection point. It also means that the first connecting component 1 can change its position relative to the second connecting component 2. A connection point is provided on the second connecting component 2. This connection point can refer to any location on the second connecting component 2 or a component designated as a "connection point" provided at any location on the second connecting component 2. "Rotate about the connection point" means that the first connecting component 1 can rotate relative to the connection point.

[0034] It should also be noted that the length direction of the second connecting assembly 2 is the same as the axial extension direction of the pipe 5 .

[0035] When assembling the pipe fitting 5, first connect the first connecting component 1 to the pipe fitting 5 through the pipe fitting fixing piece 12, and connect the second connecting component 2 to the segmented shell plate 4 through the segmented shell plate fixing piece 21. Since the second connecting component 2 and the segmented shell plate 4 are fixed, it is necessary to adjust the position of the first connecting component 1 relative to the second connecting component 2 before welding the pipe fitting 5. The installation position and angle of the pipe fitting 5 can be adjusted. After the adjustment is completed, fix the first connecting component 1 so that the pipe fitting 5 remains stationary relative to the segmented shell plate 4, and finally start welding the pipe fitting 5.

[0036] Among them, the first connecting component 1 includes a moving part 10 and an adjusting part 11, and a pipe fixing part 12 is provided at one end of the moving part 10; one end of the adjusting part 11 is connected to the connection point, and the other end is movably connected to the moving part 10 to drive the moving part 10 to move along the length direction of the second connecting component 2.

[0037] In some possible embodiments, the moving part 10 is a first screw, the adjusting part 11 is a first nut, the first nut is rotatably connected to the connection point, the first nut is sleeved on the surface of the first screw, and is threadedly connected to the first screw.

[0038] The connection point in this embodiment refers to any point on the second connection component 2. In this embodiment, the length extension direction of the first screw can be as follows: Figure 1 As shown, the length extension direction is the same as that of the second connecting component 2, or it can be different from the length extension direction of the second connecting component 2. For ease of explanation, here, the length extension direction of the first screw is the same as that of the second connecting component 2. As an example, the first screw is arranged vertically, and since the first nut is rotatably connected to the connection point, in order to ensure that the first screw can move along the length extension direction of the second connecting component 2, the axial extension direction of the first nut also needs to be the same as the length extension direction of the second connecting component 2.

[0039] The first nut is installed at the connection point. To enable the first connection component 1 to rotate about the connection point, the first nut is provided at the connection point for rotational connection with the second connection component 2. Specifically, a rotation protrusion is provided on one side of the first nut, which is provided at the connection point and is rotationally connected to the second connection component 2. The first screw is passed through the first nut. When the first screw or the first nut rotates, the first screw moves along the length extension direction of the second connection component 2, thereby adjusting the height of the pipe 5 relative to the segmented shell 4.

[0040] Specifically, when the first screw rotates, the first nut cannot rotate on its own. Therefore, rotating the first screw can cause the first screw itself to move along the length of the second connecting assembly 2. To prevent the pipe 5 from rotating due to the rotation of the first screw, the first screw is rotatably connected to the pipe fixture 12. In this case, when the first screw rotates, the height of the pipe 5 relative to the segmented shell 4 can be adjusted, and when the first nut rotates, the angle of the pipe 5 relative to the segmented shell 4 can be adjusted.

[0041] When the first screw can only move along the length of the second connecting assembly 2 and cannot rotate, the first nut can also rotate on its own while rotating on the second connecting assembly 2. A sliding groove can be provided on the outer circumferential surface of the first nut so that a rotating protrusion slides within the sliding groove. When the rotating protrusion slides one circle within the sliding groove, the first nut rotates one circle. It should be noted that the direction of rotation of the first nut on the second connecting assembly 2 is different from the direction of its own rotation. When the first nut rotates on its own, the height of the pipe fitting 5 relative to the segmented shell plate 4 can be adjusted. When the first nut rotates on the second connecting assembly 2, the angle of the pipe fitting 5 relative to the segmented shell plate 4 can be adjusted.

[0042] In other possible embodiments, a rotating rod 7 is provided on the connection point, and the rotating rod 7 serves as a rotating joint. The rotating rod 7 is rotatably connected to the second connecting component 2. The movable part 10 is a first screw. The first screw has a first through groove 100 along the axial direction of the first screw. The rotating rod 7 is provided with the first through groove 100. Two adjusting parts 11 are provided, and the adjusting parts 11 are first nuts. The first nut is threadedly connected to the outer peripheral surface of the first screw. The rotating rod 7 is configured as follows: when the rotating rod 7 is provided in the first through groove 100, the rotating rod 7 is located between the two first nuts.

[0043] In this embodiment, the connection point refers to any point on the second connecting assembly 2. To adjust the height of the pipe 5 relative to the segmented shell 4, the rotating rod 7 is slid within the first through slot 100. After confirming the height of the pipe 5 relative to the segmented shell 4, the two first nuts are engaged with the rotating rod 7, clamping the rotating rod 7 to secure the first screw to the second connecting assembly 2. Rotating the rotating rod 7 adjusts the angle of the pipe 5 relative to the segmented shell 4.

[0044] In this embodiment, a set of first connecting components 1 can be provided for use in conjunction with a set of second connecting components 2. Alternatively, the first connecting components 1 and the second connecting components 2 can be provided on both sides of the pipe 5. On this basis, the pipe auxiliary installation device further includes a connecting member 3 connected to the rotating rod 7, with the connecting member 3 extending in a direction perpendicular to the direction of extension of the second connecting component 2. Two sets of first connecting components 1 are provided, and the two sets of first connecting components 1 are movably connected to both sides of the connecting member 3, so that the relative distance between the two sets of first connecting components 1 is adjustable.

[0045] Specifically, the movable members 10 in the two groups of first connecting assemblies 1 are connected by the connecting member 3. The two movable members 10 can be symmetrically arranged on both sides of the pipe 5 and the connecting member 3 with the central axis of the pipe 5 as the center line. They are connected to the pipe 5 through the pipe fixing member 12 provided on each group of first connecting assemblies 1, so that the first connecting assembly 1 is more stable when driving the pipe 5 to adjust. A connecting groove 30 can be provided on the connecting member 3, and the length extension direction of the connecting groove 30 is perpendicular to the axial extension direction of the pipe 5. The two movable members 10 slide in the connecting groove 30 and can be connected to pipes 5 of different diameters. On this basis, a rotating rod 7 can be provided to connect to the connecting member 3, that is, a rotating rod 7 is fixedly connected to each end of the connecting member 3. When the moving part 10 is a first screw, the first screw is passed through a connecting groove 30. When adjusting the height of the pipe 5 relative to the segmented shell plate 4, the first screw is made to slide in the connecting groove 30. The sliding direction there is the same as the extension direction of the central axis of the pipe 5. The two first nuts are respectively arranged at the top and bottom of the connecting part 3. After confirming the height of the pipe 5 relative to the segmented shell plate 4, the two first nuts are made to fit with the connecting part 3 and clamp the connecting part 3. At this time, the first screw is fixed to the second connecting component 2 through the connecting part 3 and the rotating rod 7.

[0046] The above embodiments are merely multiple possible implementations of the embodiments of the present application, and the embodiments of the present application are not limited thereto.

[0047] Based on the above embodiment, in this embodiment, the pipe fixing member 12 includes: a fixing stud 121 and a pad 120, the fixing stud 121 is used to be detachably connected to the pipe 5; one end of the pad 120 is connected to the fixing stud 121, and the other end is connected to the first connecting component 1.

[0048] In this embodiment, there is no restriction on the shape of the pad 120. For example, the pad 120 can be a square plate structure or a circular plate structure. Two holes are provided on the pad 120. The fixing stud 121 fixes the pad 120 to the pipe 5 through the inner hole, and the moving part 10 is connected to the pad 120 through the outer hole.

[0049] On the basis of the above embodiment, in this embodiment, the second connecting component 2 includes a positioning member 20. Along the length direction of the second connecting component 2, a second through slot 200 is opened on the positioning member 20, and the rotating rod 7 is slidably connected inside the second through slot 200.

[0050] In this embodiment, when the height of the pipe 5 relative to the segmented shell 4 is adjusted, the rotating rod 7 can slide within the second through-slot 200. In this case, the connection point can be anywhere on the positioning member 20. For example, if the positioning member 20 is a second screw, when the rotating rod 7 is restrained by two second nuts, the position of the rotating rod 7 is the connection point. The restraint here means that the rotating rod 7 is restricted from sliding along the length direction of the second connecting assembly 2 within the second through-slot 200, but can rotate within the second through-slot 200.

[0051] Since the segmented shell plate 4 is made of an iron alloy, a switch magnet 210 is provided as the segmented shell plate fixing member 21 to facilitate connection thereto. One end of the switch magnet 210 is fixed to the second connecting assembly 2, and the other end is used to connect to the segmented shell plate 4. When the second connecting assembly 2 is to be fixed to the segmented shell plate 4, the switch magnet 210 is energized to attach to the segmented shell plate 4. When the second connecting assembly 2 is to be separated from the segmented shell plate 4, the switch magnet 210 is powered off.

[0052] In order to make the first connecting component 1 drive the pipe 5 to rotate more stably, based on the above embodiment, in this embodiment, an adjustment plate 6 is connected between the first connecting component 1 and the second connecting component 2, and the first connecting component 1 is slidingly connected to the adjustment plate 6, and the sliding trajectory of the first connecting component 1 on the adjustment plate 6 is an arc.

[0053] In some embodiments, one side of the adjustment plate 6 can be fixed to the positioning member 20, and an arc groove 60 is provided on the other side of the adjustment plate 6. A fastener is provided on the first connecting component 1, and one end of the fastener is penetrated by the arc groove 60 and is used to slide in the arc groove 60. Since the moving member 10 can move along the length direction of the positioning member 20, the fastener is slidably connected to the moving member 10. When the first through groove 100 is provided on the moving member 10, the fastener can penetrate the first through groove 100 and slide in the first through groove 100. A threaded groove is provided on the end of the fastener away from the positioning member 20. After the angle of the pipe 5 is adjusted, the fastener is fixed to the moving member 10 by a fixing nut. At this time, the fastener is pressed against the arc groove 60 to limit the moving member 10.

[0054] In other embodiments, the adjustment plate 6 is disposed between the positioning member 20 and the moving member 10. The adjustment plate 6 can also be slidably connected to both the positioning member 20 and the moving member 10, so that the adjustment plate 6 can adjust the spacing between the segmented shell plate 4. In this embodiment, arc grooves 60 are provided on both sides of the adjustment plate 6, and the arc grooves 60 on both sides can be connected. Fasteners are provided on the first connecting component 1 and the second connecting component 2, that is, fasteners are provided on both the moving member 10 and the positioning member 20. One end of the fastener is penetrated by the arc groove 60 and is used to slide in the arc groove 60. Figure 2 As shown, when the two fasteners overlap in the direction perpendicular to the central axis of the pipe 5, the segmented shell 4 and the pipe 5 are arranged vertically; when the angle of the pipe 5 relative to the segmented shell 4 is adjusted, as shown in FIG. Figure 4 As shown, the two fastening members do not overlap in the direction perpendicular to the central axis of the pipe 5 .
