Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to an assembly structure and a lifting method for integrated lifting of a boarding ladder and a lift. Background Art

[0002] As an important resource in the shipyard, cranes are very busy. In order to make up for the shortage of cranes, some cabin outfitting parts are transported by a combination of elevators and boarding ladders. The elevators transport the outfitting parts and the boarding ladders are for people to walk on. However, after actual use, because the ship is built in blocks, the blocks are shifted as a whole, and the blocks can be shifted quickly, while the boarding ladder and elevator combination does not consider overall lifting. It is necessary to first dismantle the elevator car, motor, modular columns and other parts, transfer them to the assembly platform, and then hoist the boarding ladder to the assembly platform for positioning. Then, use the truck crane to assemble the various parts of the elevator based on the boarding ladder, and it can be put into use after power-on debugging. The dismantling, shifting and reassembly cycle requires the cooperation of the truck crane, which requires at least 15 days of operation cycle. Therefore, after the block is shifted, there are many problems such as boarding and outfitting parts on board.

[0003] The traditional method of relocating the elevator and the boarding ladder requires disassembling the elevator and the boarding ladder, moving them to the required place and reassembling them, which consumes a lot of manpower and time costs for disassembly and assembly. In addition, when the elevator was initially transporting outfitting parts, a forklift was used to place the goods directly in the elevator car. Because the goods were heavy, when the forklift was placed directly in the elevator car, there was a certain impact force on the car, which easily caused the weight limit overload phenomenon in the car, and it needed to be stopped for 2-3 minutes. The elevator could not be started until the weight limit switch was restored, which also reduced the operating efficiency of the equipment. Summary of the invention

[0049] Embodiment 1

[0050] like Figures 1 to 3 As shown, this embodiment provides an assembly structure for integrated lifting of a boarding ladder and a lift, the assembly structure comprising:

[0051] The common base 301 includes a plurality of support bars staggered horizontally and vertically in a plane, and the plurality of support bars form a plurality of rectangular frames inside the common base 301; the common base 301 is placed on the ground, and temporary gaskets 305 are provided at the corners of the lower surface of the rectangular frames in contact with the ground, and the temporary gaskets 305 are used to adjust the levelness of the common base 301 and the ground. The temporary gaskets 305 are checked for levelness with a total station, and the height difference is controlled within ±2mm. If the gaskets are of different thicknesses for easy adjustment, the temporary gaskets 305 are not welded to the common base 301.

[0052] The boarding ladder base 302 and the elevator base 304 are fixed side by side on the common base 301. Welding gaskets 303 are provided between the boarding ladder base and the common base 301 and between the elevator base and the common base 301 to adjust the horizontality. The upper and lower sides of the welding gaskets 303 are fixed by welding.

[0055] The boarding ladder and the lift have a common first central axis, the boarding ladder has a second central axis perpendicular to the first central axis, the first and second main load-bearing hoisting horses are symmetrically arranged about the first central axis, the third and fourth main load-bearing hoisting horses are symmetrically arranged about the first central axis, the first and second main load-bearing hoisting horses are located on a side of the second central axis away from the lift. The first and third main load-bearing hoisting horses are located on the same outer wall surface, and the second and fourth main load-bearing hoisting horses are located on the same outer wall surface.

[0056] Furthermore, the vertical thick steel plate 005 is fixed with vertically arranged reinforcing ribs 006 and horizontally arranged structural steel 101 on the inner side away from the main load-bearing hoisting horse 007. The vertical thick steel plate 005, the reinforcing ribs 006 and the structural steel 101 intersect and are welded at the intersection. Since the single vertical thick steel plate 005 has limited load-bearing capacity, it is easy to deform or even break due to excessive force when the boarding ladder and the elevator are hoisted by the hoisting horse, so it needs to be structurally reinforced; and the corners themselves have been reinforced, so there is no need to add additional structural parts.

[0057] Furthermore, a horizontally arranged U-shaped reinforcement 008 is welded to the lower half of the main load-bearing hoist 007, and the U-shaped reinforcement 008 extends along the circumference of the boarding ladder, i.e., covers the outer wall surface of the boarding ladder, and the opening of the U-shaped reinforcement faces the outside of the boarding ladder.

[0058] Furthermore, the segment of the vertical thick steel plate 005 located below the U-shaped reinforcement 008 is welded to the upper end of the herringbone reinforcement (including the first diagonal member 009 and the second diagonal member 010), and the lower end of the herringbone reinforcement is welded to the structural steel of the boarding ladder.

[0059] At the same time, a herringbone reinforcement (including the third diagonal member 013 and the fourth diagonal member 014) is also welded on the vertical structural column at the bottom of the boarding ladder, and the upper end of the herringbone reinforcement is welded to the vertical structural column at the bottom of the boarding ladder, and the lower end is welded to the common base 301 below the boarding ladder.

The small clamp 402 is used to clamp on the vertical support column 200 of the elevator, and the large clamp 406 is used to clamp on the vertical support column 207 of the boarding ladder, so as to adjust the distance between the elevator and the boarding ladder to ensure the verticality of the elevator. The horizontal tie rod is arranged horizontally, and the inclined tie rod is arranged obliquely. A plurality of horizontal tie rods and inclined tie rods are arranged alternately in the vertical direction, and the horizontal tie rod is located at the bottom.

[0061] A car 502 is installed on the side wall of the elevator away from the boarding ladder. The car 502 is driven up and down by a motor to transport goods.

[0062] Furthermore, if Fig. 9 , Fig.10 As shown, a leveling hoist 002 is provided on the seventh layer where the boarding ladder is located at the top. The leveling hoist 002 is welded on the extension tube of the main steel pipe structure of the boarding ladder to arrange the auxiliary hook 511 of the crane. The leveling hoist 002 is used together with the main load-bearing hoist during lifting.

[0063] The extension tube includes two horizontal extension tubes 001 and an oblique extension tube 003 located below the horizontal extension tubes. The two horizontal extension tubes 001 are symmetrically arranged about the first central axis. The first end of the horizontal extension tube 001 is fixed to the corner of the boarding ladder close to the elevator, and the second end intersects with the end of the oblique extension tube 003. The end of the oblique extension tube 003 away from the horizontal extension tube 001 is also welded to the corner of the boarding ladder close to the elevator. The second ends of the two horizontal extension tubes 001 are also connected by a horizontal connecting tube 004, and the leveling hoist 002 is located in the middle of the horizontal connecting tube 004.

[0064] Furthermore, the assembly structure also includes a temporary cargo platform 310, which is located on the side of the elevator away from the boarding ladder, and the upper surface of the temporary cargo platform 310 is flush with the bottom surface of the car. Before the elevator carries the cargo, the cargo is first placed on the temporary cargo platform 310, and then transferred to the elevator car with a trolley. The cargo is then transported to the locked height, and the car moves to the bottom after unloading the cargo, completing the cargo transportation cycle.
