[0001] The present application belongs to the technical field of ship liquid tank correction, and specifically relates to a ship liquid tank segment structure deformation correction tool and a correction method. Background Art

[0002] The tank section composed of the keel and the side is an important part of the ship, which is responsible for water storage and drainage. Its construction quality is directly related to the product safety factor. Therefore, there are very high process standards and technical requirements in the actual construction.

[0003] The keel section and side section of the tank are usually built on a specially made cradle, using the positive construction method, first laying the outer shell plate, then hoisting the ribs, longitudinal support bones, transverse bulkhead plates and other structures, and lowering the cradle after the internal structure is welded. Due to the complex and dense structure, the welding workload is large, and the stress generated by welding is concentrated, which will cause the rib plate structure to have a large "dumping" deformation phenomenon.

[0004] In order to ensure the manufacturing accuracy of the tank segments and ensure that the verticality and spacing of the ribs meet the process quality requirements, the segments need to be stress-relieved and a large amount of deformation correction work is required after welding. The traditional welding deformation correction method uses a basket screw to hook and pull the ribs to reset. This correction method has at least the following defects:

[0005] 1. The labor intensity is high, the correction efficiency is low, and the strength requirements for the basket screws are very high; 2. The basket screws do not have sufficient stress-bearing points and need to be welded to the shell plate or other structures with the help of horse plates, which affects the quality and appearance of the product itself, and there are major safety hazards during the hooking process.

DETAILED DESCRIPTION

[0036] 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.

[0037] 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.

[0038] 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.

[0039] The embodiment of the present invention discloses a ship tank segment structure deformation correction tool and correction method, which can solve the technical problems of low correction efficiency and potential safety hazards, thereby improving the efficiency of segment correction and reducing the impact on the construction appearance.

[0040] The technical solution of the present application is described in detail below through specific embodiments:

[0041] See also Figure 1 In the first aspect of the present application, a ship tank segment structure deformation correction tool 1000 is provided, which includes a main body 1100 and two adjustment structures 1200. The two adjustment structures 1200 are respectively installed at both ends of the main body 1100, and the adjustment structure 1200 includes an adjustment sleeve 1210, a support block 1220 for cooperating with the bulkhead 3000 or the rib plate, and a positioning block 1230 for fixing the adjustment sleeve 1210. The adjustment sleeve 1210 is slidably matched with the main body 1100, and the adjustment sleeve 1210 can move along the axial direction of the main body 1100, and the sliding directions of the two adjustment sleeves 1210 are parallel. The positioning block 1230 is used to limit the position of the adjustment sleeve 1210. When the adjustment sleeve 1210 moves to a preset position, the position of the adjustment sleeve 1210 can be fixed by the positioning block 1230. The support block 1220 is disposed at one end of the adjustment sleeve 1210 away from the main body 1100 , and the two support blocks 1220 are located at two ends of the correction tool 1000 .

[0042] See also Figure 1 , Figure 2 and Figure 3 In one embodiment, the adjusting sleeve 1210 and the main body 1100 are connected by threaded fitting. By rotating the adjusting sleeve 1210 and the main body 1100 relative to each other, the relative position of the adjusting sleeve 1210 can be changed, thereby changing the distance between the two support blocks 1220. Threaded fitting has the characteristics of high adjustment accuracy and convenient adjustment. The length of the correction tool 1000 can be adjusted by threading with higher accuracy and operability. Of course, the threaded fitting connection between the adjusting sleeve 1210 and the main body 1100 is only one implementation in the present embodiment. In other implementations, it is also possible to set the adjusting sleeve 1210 and the main body 1100 to be sliding fitting. It is only necessary to fix the position of the adjusting sleeve 1210 by the positioning block 1230 after the adjusting sleeve 1210 moves to the preset position.

[0043] In one embodiment, a mounting hole 1211 is provided on the adjustment sleeve 1210, and an internal thread is provided on the inner wall of the mounting hole 1211. External threads for matching with the internal threads on the mounting hole 1211 are provided at both ends of the main body 1100, respectively. The external threads may be arranged on the entire main body 1100, or may be arranged only at both ends of the main body 1100. In order to facilitate the movement of the main body 1100, the mounting hole 1211 is usually arranged longer. Considering that the torque is large when too many threads are matched, only a section of internal thread may be arranged at the opening of the mounting hole 1211. In another embodiment, the mounting hole 1211 is arranged on the main body 1100, and the external thread is arranged on the adjustment sleeve 1210.

[0044] In one embodiment, the mounting hole 1211 may penetrate the adjusting sleeve 1210 along the axial direction of the adjusting sleeve 1210 to make the adjusting sleeve 1210 cylindrical.

[0045] In one embodiment, the positioning block 1230 can be sleeved on the main body 1100, and the positioning block 1230 and the main body 1100 are also connected by threaded fitting, and the positioning block 1230 is located on the inner side of the adjustment sleeve 1210. When the adjustment sleeve 1210 moves to the preset position, the positioning block 1230 is screwed to form abutment with the adjustment sleeve 1210. At this time, the positioning block 1230 can limit the position of the adjustment sleeve 1210, and the position of the adjustment sleeve 1210 is limited to this position and cannot continue to move inward. When correcting, the rib plate will only apply pressure to the adjustment sleeve 1210 from the outside, so that the adjustment sleeve 1210 cannot move outward. In another embodiment, the positioning block 1230 can be screwed to the preset position first, and then the adjustment sleeve 1210 is rotated, and the adjustment sleeve 1210 reaches the preset position after abutting with the positioning block 1230.

[0046] The threaded fit between the positioning block 1230 and the main body 1100 is only one implementation in this embodiment. In other implementations, the positioning block 1230 and the main body 1100 may also be fitted by snap-fitting or plug-fitting.

[0047] See also Figure 2In one embodiment, the main body 1100 is provided with an adjustment hole 1130, which is perpendicular to the axis of the main body 1100 and penetrates the main body 1100 in the radial direction of the main body 1100. When adjusting the distance between the two adjustment sleeves 1210, in addition to adjusting by rotating each adjustment sleeve 1210, the positions of the two adjustment sleeves 1210 can also be adjusted simultaneously by rotating the main body 1100. The adjustment efficiency can be significantly improved by rotating the main body 1100. By inserting an auxiliary part such as a handle or a latch into the adjustment hole 1130, the main body 1100 can be easily driven to rotate by the handle or the latch.

[0048] See also Figure 2 In one embodiment, the main body 1100 includes an end 1110 and two adjustment rods 1120, and the diameter of the end 1110 is larger than the diameter of the adjustment rods 1120. The two adjustment rods 1120 are respectively located on opposite sides of the end 1110 so that the two adjustment rods 1120 are coaxially arranged, the external thread is arranged on the adjustment rod 1120, and the adjustment hole 1130 is arranged on the end 1110. If the position adjustment of the adjustment sleeve 1210 is achieved by rotating the main body 1100, the torque on the main body 1100 at the position of the adjustment hole 1130 is relatively large, and the main body 1100 may be deformed at this location. After the end 1110 is arranged, the diameter of the main body 1100 at the position of the adjustment hole 1130 can be increased, thereby improving its ability to resist deformation.

[0049] See also Figure 4 In one embodiment, the support block 1220 includes a positioning portion 1221 and a supporting portion 1222. The positioning portion 1221 is plate-shaped, connected to the end of the adjustment sleeve 1210 away from the main body 1100, and the positioning portion 1221 is perpendicular to the axis of the adjustment sleeve 1210. One end surface of the positioning portion 1221 is connected to the connecting sleeve, and the flat end surface is more convenient for assembly and has a higher verticality; the other end surface of the positioning portion 1221 is used to cooperate with the rib plate or the bulkhead 3000, so that the main body 1100 and the connecting sleeve can be just perpendicular to the rib plate and the bulkhead 3000.

[0050] The support part 1222 is connected to the positioning part 1221, and the support part 1222 is vertically arranged with the positioning part 1221. The support part 1222 cooperates with the positioning part 1221 to be connected with the rib plate or the bulkhead 3000. When the positioning part 1221 abuts against the rib plate or the bulkhead 3000, the support part 1222 is positioned and limited from the top or side wall of the rib plate or the bulkhead 3000 to ensure the stability of the connection between the support block 1220 and the rib plate or the bulkhead 3000. For example, when the distance between the first rib plate 4000 and the bulkhead 3000 is greater than the rib spacing required on the process drawing, since the distance between the end faces of the two top parts is equal to the rib spacing required on the process drawing, at this time, the support part 1222 is overlapped on the top of the first rib plate 4000 to prevent the correction tool 1000 from falling directly, thereby ensuring the stability and effectiveness of the correction tool 1000.

[0051] Through the above embodiments, it can be known that the ship tank segment structure deformation correction tool 1000 disclosed in the present application can be corrected quickly, which improves the ship tank segment correction efficiency, and no modification is required on the existing construction, so it will not cause direct damage to the existing construction, saves the production cycle, improves the construction efficiency, and also improves the appearance quality of the construction, and can effectively avoid the safety hazards caused by welding. In addition, the ship tank segment structure deformation correction tool 1000 disclosed in the present application has a simple structure, convenient and flexible operation, large adjustable margin, wide application range, and sufficient strength to meet the common ship tank segment structure deformation correction needs, and can be promoted and used as a special correction tool 1000.

[0052] Based on the same inventive concept, Figure 5 , Figure 6 , Figure 7 and Figure 8 The second embodiment of the present application discloses a correction method of a ship tank segment structure deformation correction tool 1000 based on any embodiment of the first aspect, which comprises the following steps:

[0053] Step 1: Adjust the distance between the two adjustment structures 1200 of the correction tool 1000, and adjust the distance between the two support blocks 1220 to the rib spacing required on the process drawing;

[0054] Step 2: Check the state of the rib after welding. If the state of the rib is inconsistent with the state required on the process drawing, use the correction tool 1000 and the supporting device 2000 to adjust the state of the rib;

[0055] Step 3: Repeat step 2 until the status of each rib is consistent with the status required on the process drawing.

[0056] The correction method disclosed in the present application can quickly perform correction without modifying the existing construction, thereby improving the correction efficiency and effectively avoiding the safety hazards caused by welding.

[0057] In one embodiment, it is necessary to determine the inclination direction of the rib plate, and the supporting device 2000 is set in front of the inclination direction of the rib plate, and the correction tool 1000 is installed on the other side of the rib plate. If the rib plate is inclined toward the front, the supporting device 2000 is installed in front of the rib plate, and the correction tool 1000 is installed behind the rib plate. By pushing the supporting device 2000, the rib plate can be deflected toward the rear, so that the verticality of the rib plate can meet the requirements. If the rib plate is inclined toward the rear, the supporting device 2000 is installed behind the rib plate, and the correction tool 1000 is installed in front of the rib plate.

[0058] In this embodiment, the direction from the rib toward the bulkhead 3000 is the front, and the direction opposite to the front is the rear.

[0059] In one embodiment, the correction method specifically corrects the first rib 4000 as follows:

[0060] Step 1: Adjust the distance between the two adjustment structures 1200 of the correction tool 1000, and adjust the distance between the two support blocks 1220 to the rib spacing required on the process drawing. Ensure that the correction tool 1000 can adapt to the actual size of the tank segment structure and prepare for subsequent correction work.

[0061] Step 2: Check the verticality of the No. 1 rib 4000 or the distance between the No. 1 rib 4000 and the bulkhead 3000 to determine the inclination direction of the No. 1 rib 4000.

[0062] ①See Figure 5 If the No. 1 rib 4000 is tilted backward, that is, the No. 1 rib 4000 is tilted toward the No. 2 rib 5000 or the distance between the No. 1 rib 4000 and the bulkhead 3000 is greater than the rib spacing required on the process drawing, the first end of the correction tool 1000 is firstly abutted against the bulkhead 3000, and the second end of the correction tool 1000 is set toward the No. 1 rib 4000. Then the supporting device 2000 is installed behind the No. 1 rib 4000, and the supporting device 2000 is used to push the No. 1 rib 4000 to deflect forward until the No. 1 rib 4000 abuts against the second end of the correction tool 1000.

[0063] ②See Figure 6If the No. 1 rib 4000 is tilted forward, that is, the No. 1 rib 4000 is tilted toward the bulkhead 3000 or the distance between the No. 1 rib 4000 and the bulkhead 3000 is less than the rib spacing required on the process drawing, the first end of the correction tool 1000 is firstly abutted against the No. 2 rib 5000, and the second end of the correction tool 1000 is set toward the No. 1 rib 4000. Then the supporting device 2000 is installed in front of the No. 1 rib 4000, and the supporting device 2000 is used to push the No. 1 rib 4000 to deflect backward until the No. 1 rib 4000 abuts against the second end of the correction tool 1000.

[0064] Then check the verticality of rib No. 1 4000 or the distance between rib No. 1 4000 and bulkhead 3000. If rib No. 1 4000 tilts forward, repeat the above operation ①; if rib No. 1 4000 tilts backward, repeat the above operation ② until the distance between rib No. 1 4000 and bulkhead 3000 is equal to the rib spacing required on the process drawing, and the correction of rib No. 1 4000 is completed.

[0065] In one embodiment, the correction method specifically corrects the second rib 5000 and subsequent ribs as follows:

[0066] Step 1: Adjust the distance between the two adjustment structures 1200 of the correction tool 1000, and adjust the distance between the two support blocks 1220 to the rib spacing required on the process drawing. Ensure that the correction tool 1000 can adapt to the actual size of the tank segment structure and prepare for subsequent correction work.

[0067] Step 2: Check the verticality of the No. 2 rib 5000 or the distance between the No. 1 rib 4000 and the bulkhead 3000 to determine the inclination direction of the No. 2 rib 5000.

[0068] ①See Figure 7 If the second rib 5000 is tilted backward, that is, the second rib 5000 is tilted toward the third rib 6000 or the distance between the second rib 5000 and the first rib 4000 is greater than the rib spacing required on the process drawing, the first end of the correction tool 1000 is firstly abutted against the first rib 4000, and the second end of the correction tool 1000 is set toward the second rib 5000. Then the supporting device 2000 is installed behind the second rib 5000, and the supporting device 2000 is used to push the second rib 5000 to deflect forward until the second rib 5000 abuts against the second end of the correction tool 1000.

[0069] ②See Figure 8If the second rib 5000 is tilted forward, that is, the second rib 5000 is tilted toward the first rib 4000 or the distance between the second rib 5000 and the first rib 4000 is less than the rib spacing required on the process drawing, the first end of the correction tool 1000 is firstly abutted against the third rib 6000, and the second end of the correction tool 1000 is set toward the second rib 5000. Then the supporting device 2000 is installed in front of the second rib 5000, and the supporting device 2000 is used to push the second rib 5000 to deflect backward until the second rib 5000 abuts against the second end of the correction tool 1000.

[0070] Then check the verticality of rib No. 5000 or the distance between rib No. 5000 and rib No. 1 4000. If rib No. 5000 tilts forward, repeat the above operation ①. If rib No. 5000 tilts backward, repeat the above operation ② until the distance between rib No. 5000 and rib No. 1 4000 is equal to the rib spacing required on the process drawing, and the correction of rib No. 5000 is completed.

[0071] Step 3: Repeat step 2 until the status of each rib is consistent with the status required on the process drawing.

[0072] When the ribs are corrected, the supporting device 2000 needs to apply thrust to the corresponding ribs, so the supporting device 2000 will be subjected to an equal reaction force. Since the position where the thrust is applied to the ribs is generally close to the top of the ribs, the position where the reaction force acts on the supporting device 2000 is also relatively high. Based on this, in this embodiment, the supporting device 2000 has two installation methods, one is to directly install the supporting device 2000 on the ribs or bulkheads 3000 adjacent to the ribs to be corrected, and the other is to set a higher support structure so that the supporting device 2000 does not contact other ribs except the ribs to be corrected.

[0073] It should be noted that if the rib correction is performed by directly installing the supporting device 2000 on the rib or bulkhead 3000, if the second rib 5000 and the subsequent ribs are tilted forward, a correction tool 1000 should be placed in front of all the ribs before the rib before correction, such as Figure 8 shown.
