Description

Technical Field

[0001] The present invention belongs to the field of shipbuilding, and particularly relates to a hull plate deformation correction tooling and method. Background Art

[0002] As Figure 1 shown, factors such as sectional hoisting, welding of outfitting structural members, and extrusion force generated by gravity between sections can all cause deformation of the hull plates. Mechanical correction is a common deformation correction method. Mechanical correction refers to applying an external correction force with the aid of correction machinery such as jacks and double-headed threaded clamps to force the deformed plates to return to a nearly flat state. In the past, the correction machinery needed to be welded and fixed near the deformation position with the aid of other tooling, and the correction range was limited. When performing large-range correction, the tooling needed to be disassembled and assembled repeatedly, resulting in high labor intensity and easy damage to the plates, and the tooling was not flexible enough to use. Therefore, there is an urgent need for a hull thin plate deformation correction tooling to solve the problems of inconvenient disassembly and assembly and limited correction range of the original tooling. The existing solutions are marine light bulkhead correction tooling and thin plate deformation correction tooling. The structural forms of such tooling often have deficiencies such as inconvenient disassembly and assembly and limited application range, and the flexibility and application range can be further improved.

Detailed implementation manners

[0033] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings, rather than all the structures.

[0034] As Figure 2 shown, in the technical solution of the present invention, a hull plate deformation correction tooling is provided, which is characterized in that the deformation correction tooling includes:

[0035] The hull plate connection mechanism 1, including two symmetrically arranged connection mechanisms on the left and right, respectively connecting the two ends of the plate to be corrected of the hull;

[0036] The conduit 2, arranged above the plate to be corrected of the hull, connecting the two hull plate connection mechanisms 1, and a through hole is provided at the center of the conduit 2;

[0037] The correction mechanism, including a press head, the correction mechanism vertically passes through the central through hole of the conduit 2 and can move up and down in the vertical direction and press tightly.

[0038] In an embodiment of the present invention, a magnet device is provided at the bottom of the hull plate connection mechanism 1, and it is adsorbed on both ends of the plate to be corrected 15 through magnets.

[0039] As Figures 3 to 4 shown, in an embodiment of the present invention, a specific structure of the hull plate connection mechanism 1 is provided, including:

[0040] The clamping feet 14 include a first cross-round tube 7 arranged horizontally, which is internally connected to the conduit 2, and a second cross-round tube 8 arranged longitudinally, connecting the clamping plate 9 and the first cross-round tube 7; the clamping plate 9 is U-shaped, formed by bending a whole plate or welding 3 part plates, and through holes are opened on both sides of the clamping plate 9; the clamping nuts 10 are coaxially welded on the through holes on both sides of the clamping plate 9; the clamping plate 9 and the clamping nuts 10 are connected to the bulb flat bar 11 at both ends of the hull plate to be corrected through the clamping bolts 6 to fix the hull plate connection mechanism 1. In this embodiment, the clamping feet 14 are welded to each other with the first cross-round tube 7, the second cross-round tube 8, the clamping plate 9 and the clamping nuts 10. The first cross-round tube 7 and the second cross-round tube 8 are made of Φ45×3mm steel pipes. The first cross-round tube 7 allows the conduit 2 to pass through to realize the adjustment of the clamping position of the clamping feet 14. The thickness of the clamping plate 9 is 5mm. Through holes with a diameter of Φ15 are opened on both sides of the clamping plate 9 and M10 clamping nuts 10 are coaxially welded, and in cooperation with M10×50mm (full thread) clamping bolts 6, the clamping feet 14 are fixed on the bulb flat bar 11.

[0041] As Figures 5 to 6 shown, in an embodiment of the present invention, the correction mechanism uses a stud press head 4, and a wrench rod 5 is provided at its top for rotating the stud press head 4 to move it in the vertical direction. In this embodiment, the stud press head 4 is welded by an M20 stud (length L = 230mm) and a Φ40 cylinder (length L = 20mm). A Φ10 through hole is opened at the top of the stud for installing the wrench rod 5 (Φ8 round bar). After applying a couple of forces to the wrench rod 5, the stud press head can be screwed to play a labor-saving role.

[0042] As Figures 7 to 8As shown, in an embodiment of the present invention, the hull plate deformation correction tooling further includes a nut sleeve mechanism 3. The nut sleeve mechanism 3 includes a sleeve 12 and a nut 13. The nut sleeve mechanism 3 is sleeved on the conduit 2 through the sleeve 12 and can move left and right along the conduit 2. When the nut sleeve mechanism 3 is provided, the correction mechanism vertically passes through the nut 13 of the nut sleeve mechanism 3 and can move up and down. In this embodiment, the conduit 2 is a Φ38×3mm steel pipe, which is used to connect the clamping feet 14 and the nut sleeve mechanism 3, and provides a force support for the pushing movement of the stud press head 4. The nut sleeve mechanism 3 is formed by welding a section of Φ45×3mm steel pipe and an M20 hexagonal thick nut. The sleeve 12 can move left and right on the conduit 2 to adjust the position of the plate correction. The screw pair composed of the stud and the hexagonal thick nut can realize the screw pushing movement of the stud press head 4 to apply a correction external force to the deformed plate. Both the first cross-shaped pipe 7 and the sleeve 12 can move in the length direction of the conduit 2 to adjust the clamping position and the correction position, adapt to the continuous position deformation correction of different frame spacings, make the tooling more flexible to use and have a wider application range. The correction tooling structure configured with the nut sleeve mechanism 3 is as Figure 9 shown.

[0043] In an embodiment of the present invention, between the two hull plate connection mechanisms 1, a plurality of nut sleeve mechanisms 3 and a plurality of corresponding correction mechanisms are provided to realize the deformation correction of multiple positions. When the conduit 2 is relatively long, between the two ends of the hull plate to be corrected, a plurality of hull plate connection mechanisms 1 can be provided to prevent the conduit from flexural bending. Each component of the correction tooling can be assembled and used as required, with higher flexibility and a wider application range.

[0044] In the technical solution of the present invention, in addition to providing a hull plate deformation correction tooling, a method for correcting the deformation of the hull plate using the above tooling is further provided. When using the tooling as Figure 9 shown for hull plate correction, the specific method is as follows:

[0045] Step 1: Fix the hull plate connection mechanism 11 at both ends of the plate to be corrected. By adjusting the position of the first cross-shaped pipe 7 in the length direction of the conduit 2, it adapts to the deformation correction within different frame spacings. The clamping plate 9, the clamping nut 10, and the clamping bolt 6 cooperate with each other, and the clamping feet 14 are fixed by tightening the bolts, which is more convenient for installation and disassembly; further adjust the position of the nut sleeve mechanism 3 in the length direction of the conduit 2 to realize the continuous adjustment of the correction position;

[0046] Step 2: After the correction position is adjusted, press the stud press head 4 vertically downward until the stud press head 4 contacts the deformed area, and apply pressure to the correction mechanism for deformation correction.

[0047] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
