AI Technical Summary
Existing lifting equipment has difficulty simultaneously limiting the position of multiple seamless steel pipes, especially when there are many steel pipes. The U-shaped frame may not be able to fully accommodate all the steel pipes, resulting in unstable lifting.
A lifting device for pickling seamless steel pipes was designed. By setting a flipping mechanism and a driving mechanism on the fixed plate, and using the adjusting component to adjust the spacing of the L-shaped rods, stable lifting and limiting of different numbers of steel pipes can be achieved. The device includes the combined use of components such as the flipping mechanism, the driving mechanism, and the adjusting component.
It enables stable hoisting and positioning of different quantities of steel pipes, improving the stability and efficiency of the hoisting process.
