Example Embodiment

[0017] The technical solution of the present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0018] The heavy-duty container front-loading crane of the present invention includes a boom set based on a frame 1 and a boom lifting mechanism.

[0019] The boom includes a rotating arm 3, an upper lifting arm 7 and a lower lifting arm 8. The lower end of the rotating arm 3 is hinged on the middle and rear part of the frame 1, and a tripod 5 is provided on the upper end of the rotating arm 3. 3 The upper end is hinged on the lower angle frame body of the tripod 5 downward, the upper lifting arm 7 and the lower lifting arm 8 are arranged almost in parallel, and the rear end of the upper lifting arm 7 is hinged to the forward front of the tripod 5 On the angle frame body, the rear end of the lower lifting arm 7 forms a composite hinge with the hinge point of the rotating arm 3 and the tripod 5. The front ends of the upper and lower lift...

Abstract

The invention discloses a heavy-load-type container reach stacker crane. A suspension arm comprises a rotating arm, an upper lift arm and a lower lift arm; the front ends of the upper lift arm and the lower lift arm are provided with clamping devices; a suspension arm lift mechanism comprises front and rear connecting rod assemblies which are symmetrically arranged at two sides of the suspension arm; the front connecting rod assembly is a five-connecting-rod mechanism arranged below the front part of the suspension arm and comprises front rocker rods, front connecting rods, middle connecting rods and middle rocker rods; the rear connecting rod assembly is arranged behind the suspension arm and comprises rear rocker rods and rear connecting rods; drives of the front rocker rods and the rear rocker rods are both conventional high-power motors correspondingly arranged on a carriage; drives of the middle rocker rods are low-power servo motors correspondingly arranged on the carriage. According to the invention, the strategy that the high-power conventional motor and the low-power servo motors are used for hybrid driving is adopted, compared with the mode of pure servo motors or hydraulic driving, the heavy-load-type container reach stacker crane has greater power output, higher reliability and larger working space; meanwhile, the whole crane is low in manufacturing cos, and is low in maintaining cost.

Description

(1) Technical field: [0001] The invention relates to port hoisting machinery, in particular to a heavy-duty 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, short service life, and oi...
