The invention discloses a lifting mechanism of quay cranes and a method for lifting quay crane components by adopting the lifting mechanism. The lifting mechanism comprises a door frame, end beams, lifting hydraulic cylinders, a micro control unit, a drive unit and a detecting unit, wherein the end beams are rigidly connected with each other through a beam; the lifting hydraulic cylinders are arranged at the top ends of uprights and comprise punched core hydraulic cylinders and anchor tool hydraulic cylinders; the anchor tool hydraulic cylinders move with the expansion and contraction of piston rods of the punched core hydraulic cylinders; flexible steel strands penetrate the lifting hydraulic cylinders and are locked through the anchor tool hydraulic cylinders; one ends of the flexible steel strands are fixed on the outer side of the door frame through prestress anchoring devices and the other ends of the flexible steel strands are connected with support beams on the lower side of the beam through anchoring structures; the drive unit comprises an electromagnetic valve; the detecting unit generates a lifting hydraulic cylinder detecting signal and sends the signal to the micro control unit; the micro control unit receives the hydraulic lifting cylinder detecting signal and generates a control signal to drive the electromagnetic valve to work through the drive unit. According to the lifting mechanism of quay cranes, the integral and synchronous hoisting of extra-large type components at extra high altitude can be realized and the hoisting height is not limited.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a lifting mechanism of a quay crane and a method for lifting components of a quay bridge using the lifting mechanism. Background technique [0002] The large-scale container transport ships, especially the development of post-Panamax ships, have put forward higher requirements for shore-to-shore container cranes. At present, the operating speed, outreach and lifting height of the crane and the lifting rated weight of the spreader have all been significantly increased. Therefore, the loading and unloading capacity and speed of the quay crane directly determine the productivity of the terminal operation, and it is the main equipment for port container loading and unloading. [0003] The new container quay cranes newly installed in major domestic ports usually need to be able to handle various types of container ships. Taking the quay crane equipped in Qingdao Port as an examp...
