Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically to a special lifting fixture for thin-plate hulls of ships. Background Technology

[0002] When ships are constructed in sections, multiple thin plates need to be spliced ​​together and welded. Then, a large thin plate or assembly crane is used to lift it to the next process site. Since the crane usually only has four lifting points, it is easy to cause significant deformation when lifting large thin plates. This will greatly affect the assembly accuracy in subsequent splicing and assembly. In order to compensate for the impact of the deformation of the thin plate, it is necessary to rework the thin plate, which seriously affects the construction progress and reduces the construction quality.

[0003] Therefore, it is necessary to provide a special lifting fixture for thin-plate ship bodies to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a special lifting fixture for thin sheet metal in ships, which avoids deformation of large thin sheets during lifting.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A special lifting fixture for thin-plate hulls of ships includes a frame-type lifting frame composed of three crossbeams and multiple longitudinal beams. The crossbeams and longitudinal beams are arranged perpendicularly to each other. The upper surface of the lifting frame has multiple upper lifting lugs, and the lower surface of the crossbeams has multiple lower lifting lugs. The lower lifting lugs are connected to slings. The two crossbeams on both sides are connected to lifting brackets through the lower lifting lugs and slings. The crossbeam in the middle is connected to a magnetic chuck through the lower lifting lugs and slings. The lifting bracket includes a first bracket plate with an inverted T-shaped cross section. A second bracket plate is fixed to the outer side of the vertical section of the first bracket plate. The second bracket plate is connected to the first bracket plate. The vertical and horizontal sections are both vertically arranged. The inner side of the vertical section of the first code plate is fixed to the closed end of the first U-shaped code plate, and the lower surface of the horizontal section of the first code plate is fixed to the closed end of the second U-shaped code plate. Both the first and second U-shaped code plates are provided with U-shaped grooves. Threaded holes are opened on one side of both the first and second U-shaped code plates. Adjusting bolts are set on the first and second U-shaped code plates through the threaded holes to clamp the thin plate being hoisted in the U-shaped groove. A pad is provided between the adjusting bolt and the thin plate being hoisted.

[0007] Preferably, the weld joint between the crossbeam and the longitudinal beam is provided with an elbow plate.

[0008] Preferably, the lower lifting lug has three lifting holes evenly distributed along its length.

[0009] Preferably, the upper part of the vertical section of the first code plate has a through hole for threading a sling.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] 1. This fixture increases the number of lifting points to increase the stress points, evenly distribute the load across the entire thin plate, and prevent the thin plate from deforming during lifting.

[0012] 2. This fixture uses a lifting clamp to hold the edge of the thin plate, which improves the reliability of the clamping. It is also fixed to the middle of the thin plate by a magnetic chuck, which facilitates disassembly.

[0013] 3. The lifting clamp of this tooling is equipped with a first U-shaped clamp plate for horizontal clamping and a second U-shaped clamp plate for vertical clamping. When the edge of the thin plate is easy to clamp, the first U-shaped clamp plate is used to clamp and fix the thin plate. When the edge of the thin plate is welded with longitudinal girder or rib plate, the second U-shaped clamp plate is used to clamp and fix the longitudinal girder or rib plate. The choice can be made freely according to the situation. Attached Figure Description
