[0050] Working principle: When the workpiece needs to be hoisted and transported, first the trolley group 2 drives the electric hoist 4 to move to the hoisting area along the track of the guide rail 1, and then the electric hoist 4 releases the hoisting rope 5, so that the hoisting rope 5 drives the guide mechanism 6 to move downward as a whole, and the cross bar 603 in the descending state drives the slide bar 601 to move downward, and the cross bar 603 in the descending state stretches the spring 602, so that the cross bar 603 drives the splint assembly to a position suitable for clamping the workpiece, at this time, the cylinder 604 is powered on and operated, so that the output end of the operating cylinder 604 drives the connecting frame 605 to move downward, and the connecting frame 605 in the descending state drives the two adjusting frames 609 to move downward synchronously, then the descending state The adjusting frame 609 drives the two first connecting rods 6010 and the second connecting rod 6011 to move inward, so that the two first connecting rods 6010 and the second connecting rod 6011 in the inward moving state drive the two clamping plates 6012 to move close to each other. Since one adjusting frame 609 can drive one group of clamping plates 6012 to move close to each other, the two adjusting frames 609 can simultaneously drive two groups of clamping plates 6012 to move close to each other, and then the two groups of clamping plates 6012 in the close state clamp and limit the two ends of the workpiece, and the lifting rope 5 also lifts the workpiece, so that the hoisted workpiece is positioned and guided by the above structure, effectively avoiding the situation where the workpiece is prone to swinging in the air during the lifting process, and improving the passability of the lifted workpiece;
