Problems solved by technology

Since the current RMG trolley integrates the two mechanisms of the lifting mechanism and the trolley drive mechanism, the active load of the trolley is relatively large, resulting in a large inertia when the trolley st

Embodiment

[0032] like Figure 1 to Figure 4 As shown, this embodiment provides a differential rail container crane, which includes: a mast structure 1 , a trolley 3 and a driving mechanism for driving the trolley to travel on the top of the mast mechanism 1 .

[0033] Wherein, the portal frame structure 1 includes a load-bearing main beam 2 and two support frames 5 for supporting the load-bearing main beam 2 . The load-bearing main girder is a triangular tube structure single main girder and its node form is a contained node. The parameters of the single main girder of the triangular tube structure are as follows: the main chord is φ400×12, the web is φ159×10, the span is 31m, the height is 3 meters, and the section moment of inertia is 0.9×1011mm 4 , the weight per unit length including the track is 0.7 tons, and it can withstand a lifting load of 50 tons. It is the lightest product of the same type in the world. The nodes carrying the main girder adopt inclusive nodes, which greatly...

Abstract

The invention provides a differential type track container crane. The differential type track container crane comprises a portal structure, a trolley used for moving a container, and a drive mechanism driving the trolley to walk. The drive mechanism is arranged on the portal structure and not arranged on the trolley. The drive mechanism comprises eight differential reduction boxes with two freedom degrees. Container ascending and trolley walking are achieved through the same set of steel wire ropes, in other words, the eight differential reduction boxes can be connected with corresponding steel wire rope drums respectively, the first freedom degree that eight steel wire ropes are driven to achieve adjustment on ascending or descending or transportation of the container is adopted, the second freedom degree that eight steel wire ropes drag the trolley to walk in a combined movement manner at the same time is adopted, and therefore trolley walking and container ascending are integrally driven, the weight of the trolley is reduced, the movable load and the ascending or braking inertia of the trolley are reduced, and the dead load and the bearing condition of the portal structure are improved. Slipping, rail gnawing and other faults of the trolley can be avoided through dragging walking.

Description

technical field [0001] The invention belongs to the technical field of cranes and relates to a differential rail container crane. Background technique [0002] The rail-mounted container crane (RMG) is characterized by the use of a cart mechanism to walk on the track, and it is a derivative of the tire-mounted container crane (RTG). Although its application time in port terminals is relatively late, it has been widely used in automated terminals. Among the more than 4,000 field bridges (RTG and RMG are collectively referred to as field bridges in the port) produced by Shanghai Zhenhua Heavy Industry Company, about 1,000 are RMGs. [0003] Compared with rubber-tyred container cranes, rail-mounted container cranes have the following advantages: [0004] First, the running resistance of rail-mounted container cranes is smaller than that of tire-type container cranes. Since rail-mounted container cranes run on rails rather than on the ground, their running resistance is much ...
