Example 2

[0031] Based on Example 1, this example introduces a dock bottom lifting tool, such as Figure 3-Figure 6 As shown, electric cylinders 4 are fixedly installed on both sides of the inner wall of the stand 1, an adjusting plate 41 is fixedly connected to the inner wall of the adjusting groove 12, a tooth plate 42 is integrally formed in the middle of the adjusting plate 41, a ball screw 5 is rotatably connected inside the support column 2, a first bevel gear 51 is fixedly sleeved outside the ball screw 5, a transmission shaft 6 is rotatably connected inside the connecting plate 21 on one side of the support column 2, and a second bevel gear 61 and a transmission gear 62 are fixedly installed at both ends of the transmission shaft 6;

[0032] When the connecting plate 21 slides along the slide groove 14 in the adjustment groove 12, the tooth plate 42 on the top of the adjustment plate 41 can mesh with the transmission gear 62 for synchronous transmission, so that the second bevel gear 61 at the other end of the transmission shaft 6 transmits the first bevel gear 51, and then the ball screw 5 can rotate synchronously inside the support column 2. In this way, when the two sets of positioning clamps 3 clamp and position the air pipe at the bottom of the lifting tooling, the air pipe can be lifted and lowered synchronously along the support column 2, so that the air pipe is moved to the specified position at the bottom of the ship for welding, realizing the synchronous operation process of positioning, clamping and lifting of the air pipe, and improving the overall efficiency of welding multiple air pipes.

[0038] Finally, when clamping the remaining air pipes, the telescopic end of the electric cylinder 4 drives the support column 2 to reset, and the compression spring 23 at the telescopic end of the electric cylinder 4 can drive the telescopic end to reset quickly, so that the two sets of positioning clamps 3 can be quickly reset to the initial spacing, thereby facilitating the placement, clamping and positioning of the next set of air pipes. In this way, multiple sets of air pipes can be lifted and welded flat along the bottom of the dock, thereby flatly welding into stainless steel shell air pipes with a length of 26 meters.
