The invention relates to the technical field of lifting tools, and discloses a dock bottom lifting tool which comprises a rack, supporting columns and positioning clamping plates. The electric cylinders on the two sides of the rack stretch out and draw back to control the connecting plates on the two sides of the supporting columns to slide in the adjusting grooves along the sliding grooves, so that the two sets of positioning clamping plates can draw close to adjust the distance, and then the air pipe is clamped and positioned in the arc-shaped grooves; when a connecting plate slides along a sliding groove in an adjusting groove, a toothed plate at the top of an adjusting plate can be engaged with a transmission gear for synchronous transmission, so that a second bevel gear at the other end of a transmission shaft drives a first bevel gear, and a ball screw can synchronously rotate in a supporting column; in this way, when the two sets of positioning clamping plates clamp and position the air pipe at the bottom of the lifting tool, the air pipe can synchronously ascend and descend along the supporting columns, so that the air pipe is moved to the designated position of the bottom of a ship to be welded, synchronous operation of positioning, clamping and lifting of the air pipe is achieved, and the overall welding efficiency of the multiple air pipes is improved.

    本发明涉及抬升工装技术领域,公开了一种坞底抬升工装,包括台架、支撑柱、定位夹板;本发明通过台架两侧的电动缸伸缩控制支撑柱两侧连接板在调节槽中沿着滑槽进行滑动,从而使得两组定位夹板能够靠拢调整间距,进而将空气管夹持定位在弧形槽中;通过连接板沿着调节槽中滑槽滑动时,调节板顶部的齿板能够与传动齿轮啮合同步传动,使得传动轴另一端第二锥形齿轮传动第一锥形齿轮,使得滚珠丝杆能够在支撑柱内部同步转动,这样两组定位夹板在对抬升工装底部空气管夹持定位时,空气管能够沿着支撑柱同步升降,从而对空气管移动到船舶底部指定位置处进行焊接,实现了空气管定位夹持与抬升同步操作,提高了对多根空气管焊接整体的效率。
