Embodiment Construction

[0016] The technical solutions of the present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0017] The three-degree-of-freedom servo-driven closed-chain front-handling crane for containers of the present invention includes a boom and a boom lifting mechanism arranged based on a vehicle frame 1 .

[0018] The boom includes a rotating arm 10, an upper lifting arm 12 and a lower lifting arm 13, the lower end of the rotating arm 10 is hinged at the middle front part of the vehicle frame 1, and a tripod 11 is arranged corresponding to the upper end of the rotating arm 10. The lower corner of the tripod 11 is hinged to the upper end of the rotating arm 10, the upper lifting arm 12 and the lower lifting arm 13 are nearly parallel to each other, and the rear end of the upper lifting arm 12 is hinged on the forward front of the tripod 11. On the angle frame body, the rear end of the lower lifting arm 13 forms a compo...

Abstract

The invention discloses a three-degree-of-freedom servo drive loop-type container reach stacker crane. A suspension arm comprises a rotating arm, an upper lift arm and a lower lift arm; front ends of the upper lift arm and the lower lift arm are connected with a clamping device; the suspension arm lift mechanism comprises a front connecting rod assembly and a rear connecting rod assembly which are symmetrically arranged at two sides of the suspension arm; the front connecting rod assembly comprises a front rocker arm and a front connecting rod which are arranged below the front part of the suspension arm; the rear connecting rod assembly comprises a four-connecting-rod mechanism behind the suspension arm and a drive rod as well as a middle rocker arm and a middle connecting rod; the four-connecting-rod mechanism comprises a rear rocker arm, a rear connecting rod and a rear swing rod, wherein drives of the front rocker arm, the middle rocker arm and the rear rock arm are respectively rocker servo motors arranged on a carriage correspondingly. The three-degree-of-freedom servo drive loop-type container reach stacker crane provided by the invention has the advantages of large working space, flexible and variable output tracks, high positioning precision and the like, and moreover, the whole crane is low in manufacturing cost and is low maintaining cost.

Description

(1) Technical field: [0001] The invention relates to port hoisting machinery, in particular to a three-degree-of-freedom servo-driven closed-chain 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 mainte...
