Description

Technical Field

[0001] The present application belongs to the field of shipbuilding technology, and specifically relates to a shell ring and shell plate longitudinal seam assembly tool and a use method thereof. Background Art

[0002] During the NY shell ring and shell plate assembly operation, due to the processing deviation of the blanking steel plate and the influence of various factors in the assembly process, there will be a certain assembly gap at the upper (lower) port of the shell plate. When the shell plate longitudinal seam gap exceeds the maximum gap value specified in the process documents, it cannot meet the shell plate assembly and welding process requirements, and the shell plate longitudinal seam needs to be pulled together.

[0003] In the past, during the assembly of the longitudinal seams of the NY shell ring and shell plates, the common method of pulling the longitudinal seams of the shell plates together was to weld a turnbuckle rod at the (lower) end of the NY shell plate, tighten the turnbuckle rod with a crowbar, and pull the longitudinal seams of the upper (lower) end together to meet the shell plate assembly requirements, and then perform shell plate assembly and welding operations. After the welding of the longitudinal seams of the NY shell ring is completed, the turnbuckle rod is removed.

DETAILED DESCRIPTION

[0034] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0035] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0037] The embodiment of the invention discloses a shell ring and shell plate longitudinal seam assembly tool and a use method, which can solve the technical problem that the existing welding method is time-consuming and labor-intensive, thereby realizing the rapid welding of the shell plate longitudinal seam.

[0038] The technical solution of the present application is described in detail below through specific embodiments:

[0039] See also Figure 1 and Figure 2In the first embodiment of the present application, a shell ring and shell plate longitudinal seam assembly tool 1000 is provided, which includes a telescopic assembly 100 and two groups of clamping assemblies 200. The two ends of the telescopic assembly 100 are respectively provided with a first connecting portion 110. The clamping assembly 200 includes a clamp hook 210 for clamping the shell plate 2000 and a second connecting portion 240 for cooperating with the first connecting portion 110, and the second connecting portion 240 is detachably matched with the first connecting portion 110. The two groups of clamping assemblies 200 are respectively connected to the two ends of the telescopic assembly 100 through the second connecting portion 240.

[0040] When the second connection part 240 is separated from the first connection part 110, the telescopic assembly 100 and the clamping assembly 200 are separated from each other, which can be convenient for movement or storage. When the second connection part 240 is connected to the first connection part 110, the distance between the two groups of clamping assemblies 200 can be adjusted through the telescopic assembly 100, thereby adjusting the distance of the shell plate 2000.

[0041] The clamp hook 210 is used to connect with the shell plate 2000. The two clamp hooks 210 are respectively connected to two adjacent shell plates 2000. Then, the telescopic assembly 100 can adjust the distance between the two clamp hooks, thereby adjusting the distance between the two adjacent shell plates 2000. When the width of the longitudinal seam 3000 between the two shell plates 2000 meets the requirements of the process documents, the longitudinal seam 3000 can be welded.

[0042] In one embodiment, the first connection part 110 and the second connection part 240 are rotatably matched, and the rotation axis of the first connection part 110 is perpendicular to the telescopic direction of the telescopic assembly 100. By rotating the relative angle between the second connection part 240 and the first connection part 110, the angle between the two clamp hooks 210 can be changed, so that the clamp hooks 210 can adapt to shell plates 2000 of different angles and different curvatures, reducing the wear of the shell plate 2000 caused by the connection between the clamp hooks 210 and the shell plate 2000.

[0043] See also Figure 1 , Figure 3 and Figure 6 In one embodiment, one of the first connection part 110 and the second connection part 240 includes a connection plate 241, and the connection plate 241 is provided with a first connection hole. The other includes a connection block 111 and a connection bolt 112. The connection block 111 is provided with a connection groove, which extends along the width direction of the connection block 111, and the extension length of the connection groove is greater than the width of the connection plate 241. The connection block 111 is provided with a second connection hole, which is connected to the connection groove, and the connection bolt 112 is passed through the first connection hole and the second connection hole.

[0044] In order to make the adjustment of the first connection part 110 and the second connection part 240 more flexible, the two ends of the connection groove can be extended to the two end surfaces in the width direction of the connection block 111 respectively, so that the connection block 111 is C-shaped.

[0045] In the schematic diagram of this embodiment, the first connecting part 110 includes a connecting block 111 and a connecting bolt 112, and the second connecting part 240 includes a connecting plate 241. In other embodiments, it is also possible that the first connecting part 110 includes a connecting plate 241, and the second connecting part 240 includes a connecting block 111 and a connecting bolt 112.

[0046] Of course, the above embodiment only discloses a connection method between the first connection part 110 and the second connection part 240. In other embodiments, the first connection part 110 and the second connection part 240 can be two movable blocks connected by a hinge or two connecting shafts that can rotate relative to each other.

[0047] In one embodiment, the telescopic assembly 100 includes a rotating body 120 and two telescopic adjustment rods 130. The two telescopic adjustment rods 130 are slidably matched with the rotating body 120, and the telescopic adjustment rods 130 can move along the axis direction of the rotating body 120. Each telescopic adjustment rod 130 is connected to a first connecting portion 110. By adjusting the relative position of the telescopic adjustment rod 130 and the rotating body 120, the distance between the two first connecting portions 110 can be changed, thereby changing the distance between the two clamping assemblies 200.

[0048] See also Figure 3 and Figure 4 In one embodiment, the rotating body 120 and the telescopic adjustment rod 130 are threadedly matched. By rotating the telescopic adjustment rod 130 and the rotating body 120, the relative position of the telescopic adjustment rod 130 can be changed, so that the distance between the two first connecting parts 110 is changed. The threaded match has the characteristics of high adjustment accuracy and convenient adjustment. The length of the shell ring and shell plate longitudinal seam assembly tool 1000 is adjusted by thread with higher accuracy and operability. Of course, the threaded match between the telescopic adjustment rod 130 and the rotating body 120 is only one embodiment of the present embodiment. In other embodiments, it is also possible to set the telescopic adjustment rod 130 and the rotating body 120 as a sliding match. It is only necessary to fix the position of the telescopic adjustment rod 130 by the positioning block 140 after the telescopic adjustment rod 130 moves to the preset position.

[0049] In one embodiment, an adjustment through hole is provided along the axis direction of the rotating body 120, and both ends of the adjustment through hole are provided with internal threads, and the telescopic adjustment rod 130 is provided with external threads for matching with the internal threads. In order to facilitate the movement of the telescopic adjustment rod 130, the adjustment through hole is usually set longer. Considering that the torque is large when too many threads are matched, only one section of internal threads can be provided at the end of the adjustment through hole. In another embodiment, the adjustment through hole is provided on the telescopic adjustment rod 130, and the external threads are provided on the rotating body 120.

[0050] In one embodiment, the telescopic assembly 100 further includes two positioning blocks 140, which are sleeved on the telescopic adjustment rod 130, and the positioning blocks 140 are threadedly matched with the telescopic adjustment rod 130. When the telescopic adjustment rod 130 moves to the preset position, the positioning blocks 140 are screwed to form abutment with the rotating body 120, and the positioning blocks 140 can limit the position of the telescopic adjustment rod 130. The position of the telescopic adjustment rod 130 is restricted to this position and cannot continue to move inward. At this time, the longitudinal seam 3000 can be welded. In another embodiment, the positioning blocks 140 can be screwed to the preset position first, and then the telescopic adjustment rod 130 is rotated, and the rotating body 120 reaches the preset position after abutting against the positioning blocks 140.

[0051] The threaded fit between the positioning block 140 and the telescopic adjustment rod 130 is only one implementation in this embodiment. In other implementations, the positioning block 140 and the telescopic adjustment rod 130 may also be fitted by a snap fit or a plug fit.

[0052] See also Figure 5 , Figure 6 and Figure 7 In one embodiment, the clamp hook 210 includes a first clamping plate 211, a second clamping plate 212 and a third clamping plate 213, and the first clamping plate 211, the second clamping plate 212 and the third clamping plate 213 are located in the same plane. The first clamping plate 211 and the third clamping plate 213 are respectively located at both ends of the second clamping plate 212, forming a clamping effect on the shell plate 2000. A fixing bolt 220 is provided on the first clamping plate 211, and the assembly direction of the fixing bolt 220 is set along the direction from the first clamping plate 211 to the third clamping plate 213. By rotating the fixing bolt 220, the clamping force of the clamp hook 210 on the shell plate 2000 can be adjusted.

[0053] The second connection portion 240 is connected to the third clamping plate 213 and is used to cooperate with the first connection portion 110 of the telescopic assembly 100 .

[0054] In one embodiment, the direction in which the first connecting plate 241 and the second connecting plate 241 rotate relative to each other is parallel to the assembly direction of the fixing bolt 220. Thus, before assembly, the two clamping assemblies 200 can be rotated to the same side of the telescopic assembly 100. During assembly, by rotating the clamping assembly 200, the clamp hook 210 can be rotated toward the shell plate 2000. When the shell plate 2000 is located between the first clamping plate 211 and the second clamping plate 212, the shell plate 2000 can be clamped by screwing the fixing bolt 220.

[0055] In one embodiment, a horse plate 230 is further provided on the clamp hook 210, and the horse plate 230 is connected to the third clamping plate 213. The horse plate 230 and the third clamping plate 213 are vertically arranged, and the assembly direction of the horse plate 230 and the fixing bolt 220 are parallel, and the second connecting portion 240 is connected to the horse plate 230. The horse plate 230 can increase the connection strength between the first connecting portion 110 and the third clamping plate 213, and can also ensure that the weld is flat, making the construction more convenient.

[0056] In one embodiment, the clamping assembly 200 of the shell ring and shell plate longitudinal seam assembly tool 1000 includes a clamp hook 210, a connecting plate 241 and a locking bolt. The clamp hook 210 is used to clamp on the shell plate 2000, and its shape and size are designed according to the shape and size of the shell plate 2000 to ensure that the shell plate 2000 can be firmly clamped. The connecting plate 241 is welded to one end of the clamp hook 210. The telescopic assembly 100 includes a rotating body 120 provided with an internal thread, a telescopic adjustment rod 130 provided with an external thread, a positioning block 140 and a connecting block 111. The telescopic adjustment rod 130 is threadedly matched with the rotating body 120, the positioning block 140 is threadedly connected with the telescopic adjustment rod 130, the connecting block 111 is installed at the end of the telescopic adjustment rod 130, and the connecting block 111 forms a rotational match with the connecting plate 241 through the connecting bolt 112. When adjusting the width of the longitudinal seam 3000 , the distance between the two clamping assemblies 200 can be conveniently adjusted by rotating the nut or handle on the main body 120 .

[0057] Through the above embodiments, the present application has the following beneficial effects or advantages: when the width of the longitudinal seam 3000 during the shell ring assembly operation exceeds the maximum value specified in the process documents, the tool is installed on the upper (lower) mouth of the shell ring and locked with the shell plate 2000, and the shell plates 2000 on both sides are forced to converge toward the center of the longitudinal seam 3000 by adjusting the tool telescopic pull rod to tighten inward, thereby reducing the width of the longitudinal seam 3000 until the requirements of the process documents are met. The tool is kept in a tightened state to weld the longitudinal seam 3000 of the shell plate 2000, and after welding is completed, the telescopic pull rod is rotated to remove the assembly tool. The shell ring and shell plate longitudinal seam assembly tool 1000 disclosed in the present application has the advantages of simple structure, easy operation, and high adjustment accuracy. By using this tool, the width of the longitudinal seam 3000 in the shell ring assembly operation can be quickly adjusted and reduced, thereby improving assembly efficiency and quality. At the same time, the complexity and cost problems caused by the traditional method of fixing the horse plate 230 are avoided, and there is no need to weld auxiliary structures on the shell plate 2000, which reduces the assembly cost and time, and also avoids multiple damages to the shell plate 2000 itself. It not only reduces the labor intensity of pulling the longitudinal seam 3000 during the operation, but also saves operation time and improves labor efficiency.

[0058] Based on the same inventive concept, see Figure 8 The second embodiment of the present application discloses a method for using the shell ring and shell plate longitudinal seam assembly tool 1000 of any embodiment of the first embodiment, comprising the following steps:

[0060] Step 2: Connect two sets of clamping assemblies 200 to two adjacent shell plates 2000 respectively;

[0061] Step 3: Adjust the telescopic assembly 100 to contract so that the two shell plates 2000 are close to each other until the width of the longitudinal seam 3000 between the two shell plates 2000 meets the requirements of the process document;

[0062] Step 4: Keep the assembly tooling in a state and weld the longitudinal seam 3000. During the welding process, the positions of the telescopic assembly 100 and the clamping assembly 200 can be fine-tuned as needed to ensure the welding quality. Keep the tooling in a taut state to weld the longitudinal seam 3000 of the shell plate 2000. After welding, rotate the telescopic rod and remove the assembly tooling.
