Problems solved by technology
[0004] The object of the present invention is to provide a boom slewing device of a port crane, aiming at solving the problem that the boom still remains in the state after the slewing drive device stops driving due to the inertia of the hoisting object in the prior art during the hoisting process. It will drive the slewing device to rotate in the axial direction, which will cause the technical problem of wear and tear on the slewing drive device

The invention relates to the field of intelligent manufacturing equipment, in particular to a device for directly acting a lifting force on a load surface. The rotary drive assembly drives the rotary support column to rotate axially on the mounting seat, and the rotary support column is received by the rotary rolling member during the rotation process. The support of the slewing support then drives the lifting arm to rotate axially to realize the hoisting of cargo on the wharf. The slewing support column drives the connecting crankshaft to rotate axially during the rotation process. Since the connecting rod of the crankshaft is installed eccentrically on the connecting crankshaft, the The axial rotation drives the crankshaft and connecting rod to expand and contract in the horizontal direction, thereby realizing the axial expansion and contraction of the crankshaft and connecting rod in the damper. The damper buffers the expansion and contraction of the crankshaft and connecting rod, thereby slowing down the rotation of the connecting crankshaft and the slewing support column Therefore, after the slewing driving device stops driving, the slewing support column can stop rotating quickly, thereby reducing the wear of the device.
Description
technical field [0001] The invention relates to the field of intelligent manufacturing equipment, in particular to a boom slewing device of a harbor crane. Background technique [0002] At present, the jib slewing device of the port crane is installed on the base through the slewing support device, thereby supporting the jib. [0003] Because the slewing support device is subjected to the reverse force of the boom, the boom will still drive the slewing device to rotate in the axial direction after the slewing drive device stops driving due to the inertia of the hoisting object during the hoisting process of the boom. This in turn causes wear on the rotary drive. Contents of the invention [0004] The object of the present invention is to provide a boom slewing device of a port crane, aiming at solving the problem that the boom still remains in the state after the slewing drive device stops driving due to the inertia of the hoisting object in the prior art during the hoist...
