The invention relates to the technical field of
pickling lines, in particular to a feeding travelling crane for a closed automatic
pickling line, which comprises a track, a travelling mechanism and a cross beam, each lifting mechanism comprises two hydraulic cylinders and an X-shaped lifting frame, the two hydraulic cylinders are horizontally installed on the cross beam, the fixed ends of the two hydraulic cylinders are oppositely arranged, the outer ends of
piston rods of the two hydraulic cylinders are in transmission connection with the upper end of the X-shaped lifting frame, the lower end of the X-shaped lifting frame is connected with the lower frame, and the upper end of the X-shaped lifting frame is connected with the lower frame.
Piston rods of the two hydraulic cylinders extend outwards to push the upper end of the X-shaped lifting frame to be opened, so that the X-shaped lifting frame is vertically contracted, the
piston rods of the two hydraulic cylinders contract inwards to pull the upper end of the X-shaped lifting frame to be close, so that the X-shaped lifting frame extends, and the walking mechanism, the cross beam, the hydraulic cylinders, the X-shaped lifting frame, the lower frame and the hanging rod are all subjected to anti-
corrosion wrapping; all structural components and movable components are rigid components and can be wrapped in an anti-
corrosion mode, and the safety and stability of equipment are improved.
