Abstract

The invention discloses a three-freedom-degree servo-driven front lifting crane for containers. The three-freedom-degree servo-driven front lifting crane comprises a rotating arm, an upper hoisting arm and a lower hoisting arm which are arranged on the basis of a frame, wherein a lifting arm comprises the rotating arm, the upper hoisting arm and the lower hoisting arm; clamping devices are arranged at the front ends of the upper hoisting arm and the lower hoisting arm; the lifting-arm hoisting mechanism comprises a front connecting rod component, a middle connecting rod component and a rear connecting rod component which are symmetrically arranged at the two sides of the lifting arm; the front connecting rod component comprises a four-bar linkage mechanism and a transmission rod; the middle connecting rod component comprises a middle rocking rod and a middle connecting rod; the rear connecting rod component comprises a rear rocking rod and a rear connecting rod; the front rocking rod, the middle rocking rod and the rear rocking rod of the four-bar linkage mechanism are respectively driven by rocking-rod servo motors. The three-freedom-degree servo-driven front lifting crane disclosed by the invention has the advantage that the technical problems of high processing and assembling requirement, short service life, oil leakage, inflexible action and the like in a conventional two-freedom-degree hydraulic type front lifting crane for the containers are relatively well solved.

Description

(1) Technical field: [0001] The invention relates to port hoisting machinery, in particular to a three-degree-of-freedom servo-driven container front-handling crane. (2) Background technology: [0002] The container reach stacker crane (also known as the container reach stacker) is an important port machinery, which has the advantages of convenient operation and high stacking layers, and plays an important role in various port container handling, stacking and transportation operations. . For example, the disclosed container reach cranes of CN103332220A, CN101723256A, CN202322093U, CN2773035, and CN201890746U all complete work tasks through the joint drive of telescopic oil cylinder and pitching oil cylinder. [0003] However, the above-mentioned type of container reach cranes are all purely hydraulically driven, and their hydraulic systems have disadvantages such as high requirements for parts processing and assembly, high manufacturing, maintenance, and maintenance costs, ...
