Description

Port pool automated container terminal loading and unloading operation system and operational method
Technical field
The present invention relates to automated container terminal loading and unloading operation, in particular to a kind of port pool automated container terminal loading and unloading operation system and operational method.
Background technology
All adopt along bank formula layout at the automated container terminal of operation in the world at present, quayside configuration shore container crane carries out boats and ships loading and unloading operation, horizontal transport adopts AGV to carry out the transport between quayside and stockyard, stockyard adopts rail-mounted gantry crane, forms whole loading and unloading operation system; Current container ship container capacity has broken through 1.8 ten thousand TEU, and how the container ship reached port carries out efficiently loading and unloading the important means that casing working becomes the especially each hub port in each terminal of containers, its competitive power and radial force improve in shipping centre. For improving boats and ships loading and unloading operation efficiency, current harbour adopt improve shore container crane hoisting capacity, the simultaneously measure such as operation number of units that increases shore container crane, but produce little effect, and shore container crane drop into number of units many time, the wagon flow amount causing horizontal transport had increase, reasonable direction and distribution to AGV produce very big pressure, and appearance is transported " bottleneck "; For improving automated container terminal loading and unloading operation efficiency, strengthen competitive power and the radial force of harbour, adopt port pool automated container terminal loading and unloading operation system will be very effective.
Summary of the invention
The object of the present invention, being to develop a kind of port pool automated container terminal loading and unloading operation system, to improve container ship loading and unloading operation efficiency, optimal degree transports wagon flow organizing, reduce container ship in the port time in port, thus strengthen competitive power and the radial force of harbour.
A kind of technical scheme of the present invention is as follows:
Port pool automated container terminal loading and unloading operation system is made up of pond, port rail-mounted gantry crane, straddle truck and stockyard track crane. Pond, port is arranged in " recessed " font, container ship is parked in pond, port, and a track is respectively laid in Gang Chi both sides, and two door leg support structure of pond, port rail-mounted gantry crane are on the track of Gang Chi both sides, walk above pond, port, it is responsible for carrying out the handling casing working of container ship. First cantilever at the two ends of pond, port rail-mounted gantry crane and the 2nd cantilever arranged beneath container stacking district, the 2nd cantilever arranged beneath hatchway cover of the other end stacks district. Rules for the Certification of Freight Containers is arranged in Gang Chi both sides, becomes to be arranged vertically with pond, port, and Rules for the Certification of Freight Containers is furnished with stockyard track crane, is responsible for carrying out the loading and unloading operation of storage yard container. Freight container handing-over district is arranged in Rules for the Certification of Freight Containers end. Container stacking district and the freight container of Rules for the Certification of Freight Containers end below pond, port rail-mounted gantry crane first cantilever and the 2nd cantilever join between district, are furnished with the operation passage of straddle truck, carry out the transport of the container level between pond, port and stockyard.
Pond, port rail-mounted gantry crane is made up of beam structure, the first cantilever, the 2nd cantilever, door leg structure, running gear for trolley, sling lifting mechanism and cart walking mechanism etc. Beam structure and the first cantilever and the 2nd cantilever keep same level, and beam structure is supported on inside two side door leg structures, and the first cantilever and the 2nd cantilever are supported on the outside of two side door leg structures respectively.
