Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a linear outer plate segment assembly device and assembly method. Background Technology

[0002] In shipbuilding, the hull form sections are an important component of the ship's structure, and their assembly precision directly affects the overall quality and performance of the ship. Hull form sections typically consist of components such as outer plates, ribs, and elbows. The installation angles of the ribs and elbows have a decisive impact on the structural strength and dimensional accuracy of the section.

[0003] Traditional methods for assembling linear outer panels in segments rely heavily on manual measurement and experience-based adjustments. First, the outer panel is fixed to a jig. Then, using measuring tools such as splines, levels, and angle gauges, the installation position and angle of the ribs are determined point by point, followed by temporary fixing, and finally, the elbow plate is installed. This method has the following problems: First, the measurement process is cumbersome and time-consuming, typically requiring 2-3 experienced workers to spend 2-4 hours positioning a single rib. Second, accuracy is difficult to guarantee, especially in areas with significant changes in the segmented linear shape; accumulated measurement errors can lead to deviations in the rib installation angle, thus affecting the installation accuracy of the elbow plate. Third, repeated adjustments are necessary; when the rib angle is inaccurate, the elbow plate cannot fit properly, requiring readjustment of the rib position, further extending assembly time. Fourth, it is highly dependent on worker skill levels; new employees struggle to quickly master assembly techniques, resulting in inconsistent assembly quality.

[0004] With the trend towards larger and more complex ships, and the increasing demands for production efficiency and quality from shipyards, traditional assembly methods can no longer meet the needs of modern shipbuilding. Therefore, developing an assembly tooling and method that can quickly and accurately position ribs and elbows is of paramount importance. Summary of the Invention

[0005] In view of this, the present invention provides a linear outer panel segmented assembly device and assembly method. The present invention can solve the problems of difficult positioning of ribs and elbows, low accuracy and long time consumption in traditional linear outer panel segmented assembly, and significantly improve assembly accuracy and efficiency.

[0006] A linear outer panel segment assembly device includes a fixing part and an upright limiting part disposed on the top of the fixing part. The bottom of the fixing part forms a slot for locking the entire device onto the T-row panel. Fastening components are provided on both sides of the fixing part for locking the entire device onto the T-row. A first limiting groove and a second limiting groove are respectively opened at the center of the front and rear ends of the fixing part. Both the first limiting groove and the second limiting groove are connected to the slot. The upright limiting part is a hollow frame that matches the shape of the elbow plate. A third limiting groove is provided at the top center of the upright limiting part. The third limiting groove, the first limiting groove, and the second limiting groove are located on the same vertical plane to jointly hold the elbow plate so that the elbow plate remains upright.

[0007] Preferably, the fixing part includes a horizontal plate frame and side plates extending vertically downward from both sides of the horizontal plate frame. The horizontal plate frame has a slot in the center of its plate surface. A first limiting slot and a second limiting slot are provided on the front and rear sides of the horizontal plate frame and communicate with the slot. The horizontal plate frame and the side plates on both sides form a U-shaped slot. Fixing holes for installing fastening components are provided on the side plates.

[0008] Preferably, the width of the card slot matches the width of the T-row panel.

[0009] Preferably, the fastening assembly includes a fastening bolt and a nut.

[0010] Preferably, the upright limiting part is a triangular prism-shaped hollow frame, and multiple reinforcing crossbeams are evenly spaced on the inclined frame facing the rib plate.

[0011] Preferably, the linear outer panel segment assembly device is manufactured as a single piece.

[0012] A method for assembling segmented linear outer panels specifically includes the following steps: S1, after the T-row is assembled onto the linear outer plate, the linear outer plate segment assembly device is fixed on the T-row located on both sides of the outer plate according to the theoretical installation position of the rib plate. S2, insert the two elbow plates into the first limiting groove, the second limiting groove and the third limiting groove of the corresponding linear outer plate segment assembly device along the T-row panels on both sides of the outer plate, so that the elbow plates are kept upright and perpendicular to the T-row panels. S3, using hoisting equipment to hoist the rib plate to the designated position on the linear outer plate and make the rib plate fit tightly against the elbow plate; S4, perform positioning and constraint welding on the joints between the rib and the linear outer plate, the joint between the elbow plate and the linear outer plate, and the joint between the rib and the elbow plate. S5. After the positioning and constraint welding is completed, remove the linear outer plate segment assembly device, install the elbow plates in other positions and perform positioning and constraint welding with the rib plates.

[0013] Preferably, in step S1, the specific steps for fixing the linear outer panel segment assembly device onto the T-rows located on both sides of the outer panel are as follows: Based on the theoretical installation position of the ribs in the segmented structure diagram, mark the toe position line of the elbow plate on the panel of the T-row located on both sides of the outer plate. Install one set of the aforementioned linear outer panel segment assembly device on the panel of the T-row located on both sides of the outer panel; Adjust the positions of the two sets of linear outer plate segment assembly devices so that the front edge of the first limiting groove is aligned with the toe end position line of the elbow plate. Then, tighten all the fastening components to lock the positions of the two sets of linear outer panel segment assembly devices.

[0014] Preferably, in step S3, the specific steps for using hoisting equipment to hoist the rib plate to the designated position on the linear outer plate and to ensure that the rib plate and the elbow plate are tightly fitted are as follows: Using hoisting equipment, the rib plate is transferred to the top of the linear outer plate. The operator assists in adjusting the posture of the rib plate so that the bottom of the rib plate is aligned with the rib plate installation line drawn in advance on the linear outer plate. Then, slowly lower the rib plate so that it initially fits against the elbow plate; Then, the position of the rib is finely adjusted so that its bottom is completely aligned with the rib mounting line and the rib fits tightly against the elbow plate.

[0015] The beneficial effects of this invention are: 1. This invention is fixed to the T-shaped plate. By aligning the front edge of the first limiting groove on its fixing part with the toe end position line of the elbow plate, when the elbow plate is inserted into the first limiting groove, the second limiting groove, and the third limiting groove, it can not only restrict the elbow plate to a vertical state to facilitate the accurate positioning and installation of the subsequent rib plate, but also position the elbow plate to the installation position in one go. This not only improves the installation positioning accuracy of the elbow plate and the rib plate, but also improves the installation positioning efficiency of the elbow plate and the rib plate, greatly shortens the assembly time of the linear outer plate segment, and improves the assembly accuracy of the linear outer plate segment.

[0016] 2. The present invention has a simple structure and is easy and convenient to operate. It can quickly install the elbow plate and rib plate in one go, which greatly reduces the construction cost of the ship. Moreover, the device can be reused and will not damage the structure of the linear outer plate segment during use. Attached Figure Description
