Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a method for mounting and constructing hopper tanks and topside tanks of a large bulk carrier. Background Art

[0002] The loading method of the topside tanks and hopper tanks of large bulk carriers is that the topside tanks and hopper tanks are respectively formed into blocks in the block stage, and then the corresponding blocks are hoisted into the dock for loading, and the positioning of the blocks, welding, grinding, painting and other operations of the loading seams are completed. Figure 6 to Figure 7 As shown, since the ribs installed on the hull outer plate are at a certain distance from the outer plate, the traditional elevated vehicle operation method cannot penetrate into the operation blind area between the two ribs, resulting in the problems of long construction distance and difficult construction. Summary of the invention

[0003] The purpose of the present invention is to address the deficiencies in the prior art and to provide a method for carrying construction on the hopper tanks and topside tanks of a large bulk carrier, in which a construction platform is extended between the ribs of the hopper tanks.

[0004] To achieve the above object, the technical solution adopted by the present invention is: a method for loading and constructing hopper tanks and topside tanks of a large bulk carrier, comprising the following steps:

[0005] S1, block stage: fix the scaffolding ear plate to the rib web plate of the upper shell plate rib of the hopper tank, and fix the outer plate scaffolding support assembly to the hull outer plate of the hopper tank;

[0006] S2. Before the loading stage: assemble the longitudinal scaffolding board, transverse scaffolding board and belly scaffolding support components in advance and keep them ready for use;

[0007] S3, loading stage: bolt the web scaffolding support assembly to the scaffolding ear board, install the transverse scaffolding boards on the web scaffolding support assembly in turn, connect adjacent transverse scaffolding boards by fixing bolts, install the railings in turn after the transverse scaffolding boards are installed, install the longitudinal scaffolding boards on the outer board scaffolding support assembly, and connect one end of the longitudinal scaffolding board to the outer board scaffolding support assembly with steel wire, and overlap the other end of the longitudinal scaffolding board on the transverse scaffolding board, and the transverse scaffolding board and the longitudinal scaffolding board together form a construction platform.

[0008] Preferably, in step S2, the web scaffolding support assembly includes a carrying connecting plate, a scaffolding support plate and a railing sleeve, the head of the carrying connecting plate is provided with a first fixed carrying hole and a plurality of second carrying holes rotated and offset with the first carrying hole as the center and at the same radius, the scaffolding support plate is fixedly connected to the carrying connecting plate, and the side of the railing sleeve is fixedly connected to the scaffolding support plate and the carrying connecting plate at the same time.

[0009] Preferably, the second mounting holes include a second mounting hole a and a second mounting hole b.

[0010] Preferably, the second mounting hole a is located at a position rotated 2° below the center of the first mounting hole.

[0011] Preferably, the second mounting hole b is located at a position centered on the first mounting hole and rotated 30° away from the second mounting hole a.

[0012] Preferably, the scaffolding ear plate is provided with two connecting holes, and the distance between the two connecting holes is the same as the distance between the first mounting hole and the second mounting hole.

[0013] Preferably, the middle and tail portions of the mounting connecting plate are in the form of a rake-like structure, the bottom edge of the scaffolding support plate is fixedly connected to the rake-like structure, and the side of the scaffolding support plate is fixedly connected to the head portion of the mounting connecting plate.

[0015] Preferably, in step S2, two longitudinal scaffolding board single boards are spliced ​​into a whole longitudinal scaffolding board in advance, and two transverse scaffolding board single boards are staggered and spliced ​​into a whole transverse scaffolding board.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The scaffolding ear plate and the web scaffolding support assembly cooperate to form the bottom support for the transverse scaffolding board. The outer plate scaffolding support assembly is used to fix and connect the longitudinal scaffolding board and extend the construction platform to the blind area between the ribs, shortening the construction distance and reducing the construction difficulty;

[0018] 2. All scaffolding ears and outer plate scaffolding support components are installed and retained inside the structure of the hopper tank, and will not have any impact on the ship's operation in the later stage; the scaffolding ears and outer plate scaffolding support components are pre-installed in the block stage and will not affect the loading construction; after the block painting is completed, the web scaffolding support components can be pre-erected, and the loading work of the construction platform can be carried out after the hopper tank section is hoisted into the dock, which enables the process to be migrated and saves the time of on-site erection.

The side of the railing sleeve 133 is welded to the scaffolding support plate 132 and the mounting connecting plate 131 at the same time. The middle and tail of the mounting connecting plate 131 are in the shape of a nail rake. The bottom edge of the scaffolding support plate 132 is welded with a nail rake structure. The side of the scaffolding support plate 132 is welded with the head of the mounting connecting plate 131. It should be noted that the second mounting hole can be set with multiple different rotation angles for adjustment according to the on-site working angle and erection deviation. The mounting connecting plate 131 is set to be in the shape of a nail rake to reduce its own weight.

[0031] S3, loading stage: bolt the web scaffolding support assembly 13 to the scaffolding ear plate 11, install the transverse scaffolding boards 14 on the web scaffolding support assembly 13 in turn, connect adjacent transverse scaffolding boards 14 by fixing bolts 141, after the transverse scaffolding boards 14 are installed, install the handrails 16 in turn, install the longitudinal scaffolding boards 15 on the outer plate scaffolding support assembly 12, and connect one end of the longitudinal scaffolding board 15 to the outer plate scaffolding support assembly 12 with the steel wire 17, and the other end of the longitudinal scaffolding board 15 is overlapped on the transverse scaffolding board 14, and the transverse scaffolding board 14 and the longitudinal scaffolding board 15 together form a construction platform, and the steel wire 17 is used for fixing to facilitate the adjustment of the loading deviation and the subsequent dismantling.

[0032] After completing the welding, grinding, painting and other operations of the mounting seam 40 between the top side tank section 30 and the bottom side tank section 20, untie the steel wires 17 one by one from one end and remove the longitudinal scaffolding boards 15. After all the longitudinal scaffolding boards 15 are removed, untie the fixing bolts 141 one by one from one end, remove the transverse scaffolding boards 14 and release the web scaffolding support assembly 13.
