Abstract

The invention relates to a novel container yard loading and unloading process which comprises a first RMG (10), a second RMG (20), a container, a lane and a container trailer, the first RMG (10) and the second RMG (20) are both of a machine type with outer cantilevers, the outer cantilever of the first RMG (10) is higher than the outer cantilever of the second RMG (20), and the height difference of the outer cantilever of the first RMG (10) and the outer cantilever of the second RMG (20) is achieved by heightening a door leg (70), so that the minimum safe distance is achieved. An outer cantilever of the first RMG (10) is higher than an outer cantilever of the second RMG (20) and meets the requirement for the safe distance when the first RMG (10) and the second RMG (20) oppositely run and pass through, so that corresponding operation lanes are arranged below the outer cantilever of the first RMG (10) and the outer cantilever of the second RMG (20) respectively, and an overtaking lane is arranged between the two operation lanes. According to the novel container yard loading and unloading process, the distance between the two outer cantilevers RMGs is reduced to the maximum extent, so that land resources are saved, and the engineering construction cost of the container yard is reduced.

Description

Technical Field

[0001] The invention relates to the technical field of ship loaders, and in particular to a novel container yard loading and unloading process. Background Art

[0002] In the prior art, container yard loading and unloading processes mainly include RMG loading and unloading operations, tire-type container gantry crane (RTG for short) loading and unloading operations, and reach truck or forklift loading and unloading operations, and RMG is divided into RMG without external cantilever, RMG with single external cantilever and RMG with double external cantilever. For the single external cantilever RMG and double external cantilever RMG loading and unloading processes, the outreach of the RMG with a single working lane under the external cantilever is generally about 4.5m, and the length of the entire external cantilever is about 9m. However, the external cantilevers of the RMGs in the current yard loading and unloading processes with external cantilever RMGs are basically all of the same height, resulting in multiple other lanes being arranged under the external cantilever in addition to the working lane, resulting in low effective utilization of the yard, and the land resources cannot be maximized. At the same time, the cost of building this area is also high.

[0003] For example, the Chinese invention patent with the authorization announcement number CN 108298329 B discloses a new type of river-sea transport automated container terminal loading and unloading system, which includes an automated quay crane, a single-cantilever ARMG, an unmanned container truck, an in-port and out-port container truck interaction system, etc. The in-port and out-port container truck interaction system is arranged behind the yard and is used for land-based collection and distribution of containers for in-port and out-port exchange, including an interactive box temporary storage operation area and an interactive box direct loading and unloading operation area, and the two areas are operated by double-cantilever ARMG and fixed gantry cranes respectively. The invention introduces unmanned container trucks, which greatly reduces the equipment cost and supporting civil construction facility cost of automated horizontal transportation operations on the basis of realizing the fully automated operation of the loading and unloading system in the port area, and effectively solves the problems of high energy consumption, high equipment cost, and low vehicle turnover efficiency of horizontal transportation operations in conventional automated container loading and unloading systems. However, the loading and unloading system uses a double-cantilever ARMG, and the outer cantilevers of which are basically all of the same height, resulting in multiple other lanes under the outer cantilever in addition to the operating lanes. The effective utilization rate of the yard is not high, and land resources cannot be maximized. Summary of the invention

[0004] In order to solve the above technical defects existing in the prior art, the purpose of the present invention is to provide a new container yard loading and unloading process, which can minimize the distance between two external cantilever RMGs to save land resources and reduce the construction cost of container yard projects.

[0005] In order to solve the above technical problems, the solution adopted by the present invention is as follows:

[0006] The present invention provides a novel container yard loading and unloading process, which includes RMG No. 1, RMG No. 2, containers, lanes and container trailers. RMG No. 1 and RMG No. 2 are both models with external cantilevers. The external cantilever of RMG No. 1 is higher than the external cantilever of RMG No. 2, and the height difference is achieved by raising the door legs, thereby achieving a minimum safety distance. The external cantilever of RMG No. 1 is higher than the external cantilever of RMG No. 2, and meets the safety distance requirements when RMG No. 1 and RMG No. 2 pass each other in opposite directions, so there are corresponding working lanes under the external cantilever of RMG No. 1 and RMG No. 2, and a passing lane is provided between the two working lanes. The loading and unloading process of the present invention can effectively reduce the layout spacing of RMGs, improve the effective utilization rate of the yard, save land resources, and reduce the construction cost of container yards.

[0007] Preferably, the No. 1 RMG corresponds to the No. 1 container area. When operating in the No. 1 container area, the No. 1 RMG and the No. 1 container trailer arrive at the designated bay number simultaneously or successively. When taking containers, the No. 1 RMG takes out the designated container, and places the container on the No. 1 container trailer by lifting and moving the trolley. When stacking containers, the No. 1 RMG takes out the container on the No. 1 container trailer, and places the container at the designated position of the No. 1 stacking yard by lifting and moving the trolley.

[0008] In any of the above schemes, it is preferred that the No. 2 RMG corresponds to the No. 2 container area. When operating in the No. 2 container area, the No. 2 RMG and the No. 2 container trailer arrive at the designated bay number simultaneously or successively; when taking containers, the No. 2 RMG extracts the designated container, and places the container on the No. 2 container trailer by lifting and moving the trolley; when stacking containers, the No. 2 RMG extracts the container on the No. 2 container trailer, and places the container at the designated position of the No. 2 yard by lifting and moving the trolley.

[0009] In summary, the new container yard loading and unloading process of the present invention has the following advantages: the outer cantilever of RMG No. 1 is higher than the outer cantilever of RMG No. 2, and meets the safety distance requirement when RMG No. 1 and RMG No. 2 pass each other in opposite directions; it can effectively reduce the layout spacing of RMGs, improve the effective utilization rate of the yard, save land resources, and reduce the construction cost of container yard.

The loading and unloading process of the present invention can effectively reduce the layout spacing of RMG, improve the effective utilization rate of the yard, save land resources, and reduce the construction cost of the container yard.

[0015] In this embodiment, the No. 1 RMG10 corresponds to the No. 1 container area 30. When the No. 1 container area 30 is operating, the No. 1 RMG10 and the No. 1 container trailer 50 arrive at the designated bay number simultaneously or successively; when taking containers, the No. 1 RMG10 extracts the designated container, and places the container on the No. 1 container trailer 50 by lifting and moving the trolley; when stacking containers, the No. 1 RMG10 extracts the container on the No. 1 container trailer 50, and places the container at the designated position of the No. 1 stacking yard by lifting and moving the trolley.

[0016] In this embodiment, the No. 2 RMG20 corresponds to the No. 2 container area 40.
