Description

Technical Field

[0001] This invention relates to the field of adjustment devices, and more particularly to a welding-free deck flatness adjustment device for marine engineering. Background Technology

[0002] In the construction of ships and offshore platforms in marine engineering, the deck is a critical load-bearing component and working surface. The flatness of the deck affects the installation accuracy of the superstructure and the stability of equipment operation. During construction, due to changes in ambient temperature and improper welding processes, the deck is prone to localized dents and deformations.

[0003] Currently, temporary support blocks are welded next to the dent in the deck, and jacks are placed on these blocks to lift the dent. During the lifting process, a gas welding torch is used to heat the area around the dent to release internal stress in the steel plate and prevent the deck from springing back after the jacks are released. After the deck is leveled, the welded support blocks are cut off, the cut edges are ground, and finally, the area is painted. Summary of the Invention

[0004] The main objective of this invention is to provide a non-welding deck flatness adjustment device for marine engineering, in order to solve the problem in related technologies that the process of adjusting the flatness of deck pieces is complicated and difficult to adapt to the flatness adjustment of different positions of the deck.

Detailed Implementation

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] This embodiment provides a marine engineering weld-free deck flatness adjustment device, including a frame 1, such as... Figure 1 , Figure 2 As shown, the frame 1 has an H-shaped structure. Several lifting lugs 111 are fixedly installed at the edge of the upper surface of the frame 1. These lugs 111 are used to cooperate with lifting equipment to move the entire device to different positions. To facilitate movement of the device on the deck, two sets of support rods are symmetrically fixedly installed on both sides of the lower surface of the frame 1. One support rod has a fixed wheel 13 rotatably mounted at its lower end, and the other support rod has a caster wheel 131 rotatably mounted at its lower end. Operators push or pull the entire device to the vicinity of the deck deformation area. Two cross braces 12 are fixedly installed on one side of the frame 1. The cross braces 12 are L-shaped steel, and a manual hydraulic component 121 is fixedly installed on the upper surface of the cross brace 12. A hydraulic rod 122 is rotatably mounted on the upper part of the manual hydraulic component 121. The manual hydraulic component 121 provides power to the jack 32 through a hydraulic pipe. An adjustment groove 11 is formed through the center of the upper surface of the frame 1.

[0020] It also includes: adjustment unit 2, such as Figure 2 , Figure 3As shown, the adjusting part 2 is slidably disposed in the adjusting groove 11, and the adjusting part 2 includes an annular locking plate 21. The lower surface of the locking plate 21 is in contact with the upper surface of the frame 1 and slides along the adjusting groove 11, thereby driving the adjusting part 2 to adjust its lateral position. In order to fix the position of the adjusting part 2 after adjustment, a fixing screw hole 211 is provided through the edge of the upper surface of the locking plate 21. A fixing bolt is installed in the fixing screw hole 211. Tightening the fixing bolt in the fixing screw hole 211 tightens it against the upper surface of the frame 1 to fix the position of the adjusting part 2. A screw 23 is installed at the center of the locking plate 21. A crank handle 22 is threadedly installed near the upper end of the screw 23. The crank handle 22 is rotatably mounted above the locking plate 21, and the operator adjusts the position of the screw 23 by rotating the crank handle 22. The lower end of the screw 23 extends to the bottom of the frame 1 and is connected to the permanent magnet lifter 24 through the connecting frame 231. The connecting frame 231 has an inverted U-shaped structure. Its lower end is rotatably connected to the permanent magnet lifter 24, allowing the permanent magnet lifter 24 to adapt to the tilt of the deck surface. A handle 241 for controlling the magnetic circuit is located on one side of the permanent magnet lifter 24. To adjust the vertical height of the permanent magnet lifter 24, the crank handle 22 is rotated. The crank handle 22 is threaded onto the screw 23, driving the screw 23 to move up and down, thereby adjusting the height of the permanent magnet lifter 24.

[0021] Also includes: Sleeve 3, such as Figure 2 , Figure 4 As shown, two sleeves 3 are symmetrically fixedly installed on the lower surface of the frame 1, and mounting holes 31 are provided inside the sleeves 3. Several mounting screw holes 311 are provided on the upper edge of the sleeves 3, and the sleeves 3 are connected to the lower surface of the frame 1 by mounting bolts. A slot 312 is provided on the side wall of the sleeve 3, and the slot 312 communicates with the interior of the mounting holes 31. The cylinder part of the jack 32 is slidably inserted into the mounting hole 31 of the sleeve 3. The piston rod of the jack 32 extends downward. At the bottom of the jack 32, a heat insulation plate 321 is fixedly installed. The heat insulation plate 321 is made of high temperature resistant material. When heating the area around the deck depression to release stress, the heat insulation plate 321 blocks the flame or high temperature from being directly transmitted to the jack 32, preventing the jack 32 from failing due to overheating. The hydraulic pipe of the jack 32 passes through the slot 312 and connects to the manual hydraulic component 121 on the cross brace 12.

[0022] The operator moves the device to the vicinity of the deck deformation area by pushing the entire unit or using the lifting lug 111. The entire adjusting section 2 is slid along the adjusting groove 11 to align the permanent magnet lifter 24 with the center of the deck depression, and the fixing bolts are tightened to secure the lateral position of the permanent magnet lifter 24. The crank handle 22 is rotated to adjust the permanent magnet lifter 24 at the lower end of the screw 23 downwards until the bottom surface of the permanent magnet lifter 24 is in contact with the deck depression. The handle 241 on the permanent magnet lifter 24 is pulled, closing the internal magnetic circuit of the permanent magnet lifter 24 and generating a strong magnetic attraction force, attracting the permanent magnet lifter 24 to the deck position to be corrected. The operator repeatedly presses the hydraulic rod 122 on the manual hydraulic component 121. The manual hydraulic component 121 drives the piston rod of the jack 32 to extend and contact the lower deck plane. The jack 32 lifts the entire frame 1 together with the permanent magnet lifter 24 upwards. The permanent magnet lifter 24 slowly restores the dented area of ​​the deck to a horizontal position. The hot work is carried out around the dented area to prevent the adjusted deck from deforming and rebounding.
