Description

Technical Field

[0001] The invention relates to the field of shipyard plane assembly lines, in particular to a plane segmented assembly line. Background Art

[0002] The flat section assembly line is an important production facility that is indispensable for ship production in modern shipyards. Its main operating object is the parallel midship section in the ship section, that is, other sections after excluding the bow, stern, engine room area and superstructure.

[0003] The flat section assembly line is generally composed of multiple workstations. The general flat section assembly line includes the following workstations: panel positioning welding station, FCB single-sided welding station, longitudinal bone assembly station, longitudinal bone welding station, buffer and transverse shifting station, longitudinal truss and rib assembly station, longitudinal truss and rib welding station, pre-outfitting station and jacking and transporting station.

[0004] The technical parameters of a flat segmented assembly line and the producible segment characteristics are usually determined during the planning and design stage. Generally speaking, a flat segmented assembly line will determine the maximum segment size and maximum segment weight, but there is little research on the minimum segment size that can be put on line.

[0005] Generally speaking, the smallest segment that can be put on line is mainly determined by the center distance of the hydraulic jacking device of the plane segment assembly line. For segments smaller than the center distance of the hydraulic jacking device, the jacking device cannot be used, and the cranes usually equipped in the plane segment assembly line workshop are mainly used to lift components with a small rated load, so the segments cannot be lifted. Therefore, at present, many domestic shipyards are equipped with plane segment assembly lines during the construction and planning period. Due to the large center distance of the hydraulic jacking device, many small and medium-sized ships are limited by the characteristics of the hull structure and have small segment divisions, so they cannot be put on line for production. According to statistics from some domestic shipyards, the proportion of plane segments that cannot be lifted and shipped due to their small segment size is between 10% and 20% of all current plane segments.

[0006] Taking a certain flat section assembly line as an example, the center distance of the section transport trolley is 8.6m, the center distance of the hydraulic transport trolley is 11m, and there is a section scale space of about 2.4m in the middle. Since the section transport trolley can only be lifted to 0.5m at most, it cannot meet the transportation height requirement of the section transport flatbed truck. Therefore, sections between 8.6m-11.0m are usually not produced on the assembly line. According to statistics, among ships with a deadweight tonnage of less than 100,000 tons, the proportion of flat sections between 8.6m-11.0m is about 15%. Since such sections cannot be produced on the assembly line, they are currently mainly manufactured manually, which increases the cost and time of section manufacturing, and also indirectly causes the waste of production capacity of the flat section assembly line.

[0007] However, if a dedicated assembly line is arranged for such small plane segments, the cost will be too high, and when operating a large plane segment assembly line, problems such as offset will occur due to the large area. Therefore, a plane segment assembly line that can be applied to various plane segments is urgently needed in this industry. Summary of the invention

[0054] This embodiment is a planar segmented production line, comprising a segmented lifting beam and a lifting device;

[0055] like Figure 1 As shown, the lifting devices are arranged in pairs on both sides of the working area of ​​the assembly line (the spacing between the lifting devices in the horizontal direction is smaller than the distance in the vertical direction, so that large, medium and small segmented planes can all be lifted on this assembly line);

[0056] The segmented lifting beams are used in pairs during operation;

[0057] The segmented lifting beam is generally lifted and carried to the position of the assembly line work area by a lifting device during operation, so that it is arranged in the assembly line work area in a spanning manner, and its two ends are both mounted on the top of a pair of jacking devices arranged opposite to each other;

[0058] Thereby, a working area enclosed by the segmented lifting beam and the jacking device is realized as shown in the figure, and the working area is slightly narrow in the horizontal direction and slightly wide in the vertical direction.

[0059] When the segmented lifting beam is erected on the jacking device, its initial state is as follows: Figure 2 As shown in the figure, the lifting function part is located below the plane segment. When the lifting device is started to move upward, the lifting beam can move upward under the drive of the lifting device. Therefore, the segmented plane erected on it is also driven upward, and finally lifted into place to achieve the following Figure 3 After the location shown, it is transported out using other equipment.

[0060] As for the lifting beam, it can be any structure with a certain length and erection function.

[0061] In this embodiment, a segmented lifting beam capable of realizing this function is provided, and its specific structure is as follows: Figure 4-7 shown.

[0062] like Figure 4-5 As shown, the lifting beam provided in this embodiment is composed of a lifting beam body and other functional components;

[0063] The main body of the lifting beam is strip-shaped, including a main beam upper panel 1, a main beam side panel 2 and a main beam middle horizontal panel 3;

[0064] The main beam side plate 2 is a pair of side plates arranged opposite to each other;

[0065] The main beam upper panel 1 is arranged opposite to the middle horizontal panel 3 of the main beam, and forms a rectangular lifting beam main structure with the two main beam side panels 2 through welding, integrated molding, etc.

[0066] The main structure has a plurality of main beam upper ribs 7 in the cross-section for reinforcement.

[0067] The two ends of the main structure of the lifting beam are the jacking device fixing parts 1-1. During its use, after the lifting equipment lifts the entire lifting beam, the jacking device fixing parts 1-1 at its ends are aligned with the jacking equipment and then lowered to achieve positioning.

[0068] Taking into account the stability of the lifting beam after it is in place, the width of the fixing portion 1-1 of the lifting device is greater than the width of the main structure of the lifting beam.

[0069] like Figure 6As shown, the fixing part 1-1 of the jacking device also includes a lifting plate 4 at the end of the main beam and a toggle plate 8 at the end of the main beam;

[0070] The lifting plate 4 at the end of the main beam is an extension section of the middle horizontal plate 3 of the main beam, and its width is greater than the width of the middle horizontal plate 3 of the main beam.

[0071] The brackets 8 at the ends of the main beam are triangular plates, which are fixed in pairs on both sides of the main beam side plates 2, thereby achieving a triangular support effect.

[0072] like Figure 1 As shown, the top of the fixing part 1-1 of the jacking device is provided with a lifting eye 10; the component lifting eye 10 is mainly used for lifting the segmented lifting beam into place and lifting out the segmented lifting beam after segmented lifting.

[0073] The lifting eye ring 10 is composed of an eye plate 10-1 and a reinforcing bracket 10-2.

[0074] The reinforcing bracket 10-2 is fixedly mounted on the main beam upper panel 1 by welding or other methods;

[0075] The eye plate 10-1 is located on the reinforcing bracket 10-2.

[0076] In addition, if Figure 4 and 5 As shown, it also includes a lifting functional component 1-2;

[0077] The lifting functional component 1-2 is a downward extension of the middle section of the lifting beam body;

[0078] like Figure 5 and 7 As shown, the two main beam side plates 2 at the middle section pass through the middle horizontal plate 3 of the main beam and extend downward to the position of the main beam bottom plate 5, and are closed;

[0079] Similarly, in order to achieve structural reinforcement of the extended portion, a main beam lower rib 9 is also arranged in the downward extension section of the portion.

[0080] In addition, the width of the lifting functional component 1-2 is greater than the width of the main body of the lifting beam, and its extended parts on both sides form protruding wing-like structures on both sides of the middle section of the lifting beam body.

[0081] The wing-shaped structure has a plurality of lifting supports 6;

[0082] The lifting supports 6 are evenly arranged on the wing-shaped structure.

[0083] The lifting support is composed of a support web 6-1, a support panel 6-2 and a support bracket 6-3. The support web 6-1 and the support bracket 6-3 form a cross-like shape to support the support panel 6-2.

[0084] The lifting support 6 is mainly used to contact the bottom of the plane segment. When the hydraulic jacking device of the plane segment assembly line is lifted upward, the entire lifting beam will be subjected to an upward lifting force, and the force will be applied to the segment through the component 6 lifting support. When the upward lifting force is greater than the weight of the segment, the lifting support can slowly lift the segment.

[0085] In this embodiment, except for components 6 and 10, the remaining components constitute the main beam of the segmented lifting beam. The main beam is mainly used to bear the segmented weight load, provide strength to the segmented lifting beam, and ensure the stability and safety of the lifting process.

[0086] The above-mentioned components 1 to 10 are usually welded to form a whole, and the components 1 to 10 together form a segmented lifting beam. The two segmented lifting beams work together to serve as a lifting device of the hydraulic lifting device of the planar segmented assembly line, which is used for lifting and transporting smaller segments of the planar assembly line. According to different segmented structural forms and weights, the support panel (6-2) of the component 6 lifting support can be connected as a whole to increase its structural strength and stability.

[0087] As a variation of the above structure, in order to improve the stability, the lifting beam is erected behind the jacking device, such as Figure 8 As shown, the surface of the lifting device in contact with the lifting beam has a groove structure 101;

[0088] The end of the lifting beam has a protruding structure 201 at the position where it contacts the lifting device;

[0089] The groove structure 101 matches the protrusion structure 201 . When the lifting beam is lifted into place, the relative positioning between the two can be achieved by aligning the protrusion structure 201 with the groove structure 101 .
