Description

Technical Field

[0002] The hoisting and assembly of hull sections is a core step in the shipbuilding assembly process, directly determining the overall construction precision, weld quality, and overall structural stability of the ship. It is a crucial process for precision control in shipbuilding. Currently, hull sections are mostly large, thin-walled, irregularly shaped steel structures, characterized by their large volume, high weight, and complex linear structure. During dock assembly and hoisting, precise adjustments to the levelness, tilt angle, and joint gaps of the sections are required to ensure accurate matching of the end faces and weld bevels of adjacent sections, meeting the requirements of subsequent welding and forming processes. Currently, the industry commonly uses traditional construction methods for hull section hoisting and assembly, employing gantry cranes with manual assistance. The assembly fixtures used are mostly fixed support frames, simple stacking plates, and pad structures. After fixing the hull sections, assembly and welding are performed on each section in this fixed state. However, the following shortcomings still exist: The assembly tooling only has basic load-bearing, limiting and fixing functions.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] Example 1, by Figure 1 The present invention relates to a hull section hoisting and alignment assembly fixture, including a base 1, and a moving drive assembly 2 is provided at the top of the base 1. The mobile drive assembly 2 includes three mobile seats 21 arranged in a straight line. Four mobile wheels 22 are installed at the bottom of the mobile seats 21. Three slide rails 23 are installed at the top of the base 1. A sliding connecting frame 24 is installed on one side of each mobile seat 21. The three sliding connecting frames 24 are slidably connected to the three slide rails 23 respectively. A linear movement module 25 is installed between the slide rails 23 and the sliding connecting frames 24. A hoisting assembly assembly 3 is provided above the mobile seats 21.

[0018] Depend on Figure 2The hoisting assembly assembly 3 includes a loading seat 31 disposed above a movable seat 21. A rotation drive is installed inside the movable seat 21 to drive the loading seat 31 to rotate horizontally. When the three loading seats 31 rotate to a parallel state, it facilitates the loading of the bow, midship, and stern sections. When the three loading seats 31 rotate to a coaxial state and move, it enables the final connection and assembly of the bow, midship, and stern sections. A top frame 32 is disposed above the loading seat 31, and the top frame 32 is connected to the loading seat 31. Multiple support frames 33 are installed. Two hoisting drive components 36 are symmetrically installed at both ends of the top of the top frame 32. Each hoisting drive component 36 is equipped with a hoisting actuator 37. The hoisting actuator 37 is used to cover the end of the hull section, and the hoisting drive component 36 is used to hoist the end of the hull section. Two side clamping components 38 are symmetrically arranged on the bottom wall of the top frame 32. Moving rollers 34 are equidistantly installed at the top of the loading seat 31 along its length direction. Two receiving bottom grooves 35 are symmetrically opened on the loading seat 31.

[0019] Depend on Figures 4-5 The hoisting actuator 37 includes a lifting plate 371 located above the top frame 32. Hoisting ropes 372 are symmetrically installed at both ends of the lifting plate 371. A support rope 373 is installed between the bottom ends of the two lifting ropes 372, positioned below the hull. The two lifting ropes 372 are respectively positioned on both sides of the hull. The two lifting ropes 372 and the support rope 373 connected to their bottoms form a hoisting component. After the hull is loaded, the end of the hull can enter the area between the two lifting ropes 372 and the support rope 373. The hoisting actuators 37 at both ends can lift the hull, and the different lifting heights of the two hoisting actuators 37 at both ends adjust the assembly tilt angle of the hull.

After the hull is loaded, the end face of the rubber suction cups 374 can be tightly attached to the bottom of the hull for negative pressure adsorption and fixation. This improves the assembly stability and prevents the hull from slipping when tilting. The two support ropes 373 are respectively set inside the two receiving bottom grooves 35, which facilitates the movement of the hull to the inside of the two lifting ropes 372 and the support rope 373.

[0021] Depend on Figures 6-7 The side clamping component 38 includes clamping boxes 381 symmetrically installed at both ends of the bottom of the top frame 32. Two central grooves 382 are formed in the middle of the clamping boxes 381, and two lifting ropes 372 are disposed inside the central grooves 382. Two movable grooves 383 are formed inside the clamping boxes 381. A connecting groove 384 is formed at one end of the movable groove 383 near the central groove 382. A movable plate 386 is movably installed inside the movable groove 383. A clamping plate 387 is fixedly installed on the side of the movable plate 386 near the connecting groove 384. Springs 388 are symmetrically installed on the side of the movable plate 386 away from the clamping plate 387. One end of each spring 388 is fixedly connected to the inner wall of the end of the movable groove 383. A magnet 389 is installed on the movable plate 386. An electromagnet 3810 is installed on the inner wall of the end of the movable groove 383 away from the connecting groove 384. The two clamping boxes 381 are positioned opposite each other on opposite sides. The device is equipped with a side plate 3812. Two guide rods 3814 are symmetrically installed on one side of the clamping box 381. The side plate 3812 is slidably connected to the guide rods 3814. A side groove 385 is opened on one side of the movable groove 383. A side block 3811 is fixedly installed on one side of the movable plate 386. The side block 3811 is slidably connected to the side groove 385. Two connecting rods 3813 are symmetrically hinged at both ends of the side plate 3812. The ends of the two connecting rods 3813 are respectively hinged to the two side blocks 3811. Two lifting ropes 372 are located inside the middle groove 382. When the two clamping plates 387 are driven to approach each other, they can initially press the two lifting ropes 372, improving the tightness between the end faces of each rubber suction cup 374 and the hull. Later, on the one hand, it improves the tightness of the lifting ropes 372 covering the hull, improving the assembly stability, and on the other hand, it improves the centering effect of the hull, improving the assembly accuracy.

[0022] Working principle: In use, the three loading seats 31 are first rotated 90 degrees by the rotating drive between the moving seat 21 and the loading seat 31, so that the three loading seats 31 are parallel. Then, the bow section, midsection and stern section of the ship are lifted onto the three loading seats 31 in sequence to realize the loading. The moving roller 34 set on the upper surface of the loading seat 31 facilitates the movement of the ship. After the hull is loaded, the two lifting actuators 37 are located at both ends of the hull section, with the support rope 373 located at the bottom of the hull and the two lifting ropes 372 located on both sides of the hull section. Then, the double rope traction machines 362 at both ends of the top of the top frame 32 are activated to wind the traction rope 363, thereby pulling the lifting plate 371 upward until the end faces of the multiple rubber suction cups 374 on the inner side of the support rope 373 are in close contact with the bottom wall of the hull. At the same time, the electromagnet 3810 is energized, so that the electromagnet 3810 generates a repulsive force on the magnetic block 389, thereby pushing the two clamping plates 387 to move synchronously towards the inner side of the central groove 382. This causes the two clamping plates 387 to exert pressure on the two lifting ropes 372 to move away from each other, improving the covering effect of the support rope 373 on the bottom of the hull and ensuring the tightness of the end faces of each rubber suction cup 374 with the bottom of the hull. Then, the negative pressure pump 376 is turned on, and the rubber suction cups 374 are fixed to the bottom of the boat by negative pressure through the connecting hoses 377. Then, the electromagnet 3810 is de-energized, and the loading seat 31 is driven to rotate by rotating the drive component. Restarting the double-rope traction machine 362 pulls the hanging plate 371 upward, which in turn pulls the support rope 373 upward, thereby lifting the hull upward. The tilt angle of the hull is adjusted by lifting the two support ropes 373 at different heights. Because the rubber suction cup 374 is fixed to the bottom of the hull by negative pressure, the tilted hull is prevented from slipping. Then, the electromagnet 3810 is energized again, generating a repulsive force on the magnetic block 389, causing the two clamping plates 387 to move synchronously toward the interior of the central groove 382. This causes the two clamping plates 387 to press the two lifting ropes 372 away from each other, thereby improving the tightness of the lifting ropes 372 in covering the hull and improving assembly stability. On the other hand, it can also improve the centering effect of the hull and improve the assembly accuracy. Then, the linear motion module 25 drives the sliding connecting frame 24 to move along the slide rail 23, so that the three hoisting assembly components 3 are close to each other, so that the end faces of the bow section, midsection and stern section of the hull are tightly assembled, and then the contact surfaces of the three are welded together.
