摘 要:我国港口集疏运存在瓶颈,运输效率较低。为实现港区集装箱的高效快速转运,文章提出一种基于地下物流的技术方案。该方案在港区内设置地下站点,通过地下主运输隧道连接至内陆货运站,实现海陆间的无缝连接。采用自动导向运输车,设置精密的车体连接结构、定位系统、运输控制系统,解决装载运输的关键技术难题。同时设计了高精度的装卸对位系统,保证地面吊机与地下车辆的精确对位。该技术方案可实现全天候的集装箱快速转运。该研究为我国港口提供了一种新的集疏运技术途径,具有重要的工程应用前景。

Abstract: China's ports have bottlenecks in container handling and transportation, resulting in low efficiency. To achieve efficient and fast container transfer between ports, this study proposes an underground logistics-based technical solution. The solution sets up underground stations in the port area and connects them to inland freight stations through underground main transportation tunnels, realizing seamless sea-land connections. It adopts automated guided vehicles and sets up precise body connection structures, positioning systems, and transportation control systems to solve key technical challenges in loading and transportation. Meanwhile, a high-precision berthing system is designed to ensure accurate positioning between ground cranes and underground vehicles. This technical solution enables all-weather fast container transfer. This research provides a new technical approach for container handling and transportation in China's ports, and has important prospects for engineering applications.

随着全球贸易方式的改变,集装箱作为现代化货物运输的主要载体,其运输量近十年来快速增长。我国沿海主要港口的集装箱吞吐量也日益增加,据统计,全国港口在2022年全年完成集装箱吞吐量3.0亿标准集装箱(Twenty-foot Equivalent Unit,TEU) [1]。但目前港口集疏运系统中存在瓶颈,许多港区分散且直接进出的铁路不便,主要依靠公路运输将集装箱从港口输送到内陆集货中心或铁路货运站[2-3]。这不仅增加了运输环节,也使得运输效率较低,甚至公路运输还易受道路条件、交通状况等外界因素影响。因此,开发新型的集装箱转运方式以实现快速有效的港区物流运输,是当前的重要研究课题。
地下物流系统作为一种新兴的城市货运方式,自20世纪90年代在欧美等国家兴起[4]。……
