Description

Technical Field

[0001] The present invention relates to the field of container terminal transshipment, and in particular to a container terminal collection and distribution system. Background Art

[0002] In order to enable multimodal transport of cargo at container terminals by rail, road, and water, a complete and effective collection and distribution system is required. Currently, at rail-water intermodal terminals, when container ships dock, they are loaded and unloaded using loading and unloading equipment such as container gantry cranes, and container transport operations are carried out from the railway cargo yard to the terminal loading and unloading area using trucks or insulated vehicles (IGVs).

[0003] In industrial production, belt conveyors, roller conveyors and other equipment are often used for horizontal transportation of goods. Belt conveyors are generally used for the transportation of bulk materials, while roller conveyors are generally used for the transportation of packaged goods.

[0004] In urban transportation, among horizontal passenger transport systems, the SkyRail system is a suspended monorail system. As an emerging means of transportation, the SkyRail is characterized by having tracks above the vehicles, supported by steel or concrete columns. The vehicle's bogie running parts and the connection parts between the track and the vehicle are enclosed in steel track beams, and the vehicle is suspended from the bottom of the track during operation. The SkyRail system allows for flexible grouping, and its bogies use pneumatic rubber tires, which shorten the braking distance and ensure smooth vehicle operation. The construction and operating costs of the SkyRail system are lower than those of subway or light rail systems. The SkyRail system occupies a small area, which to some extent alleviates traffic congestion in ground transportation. Summary of the Invention

[0034] The present invention provides a container 6 terminal collection and distribution system composed of a container loading and unloading quay crane system 1, an automatic roller transmission system 2, an air rail system 3 and a container yard system 4. The container loading and unloading quay crane system 1 is arranged at the front of the container 6 terminal to carry out ship loading and unloading operations; the automatic roller transmission system 2 is an elevated form, arranged between the front of the terminal and the air rail system 3, and performs short-distance handover operations; the air rail system 3 is an elevated form, arranged between the terminal and the rear yard, and performs long-distance transportation operations; the container gantry crane of the container yard system 4 is arranged in the rear yard to perform container 6 stacking operations, thereby realizing intelligent unmanned operation in automatic loading and unloading, short-distance and long-distance transportation. While ensuring high transportation efficiency, the impact on ground traffic in the terminal area can be minimized, thereby maximizing the use of space.

[0035] As another embodiment of the present invention, there may be multiple container loading and unloading quay crane systems 1, each of which is arranged at a terminal, corresponding to multiple cargo yards docked at the terminal. Each of the container loading and unloading quay crane systems 1 includes a first running rail 11, a first crane installed on the first running rail 11, and a first automatic control system for controlling the first crane. One end of the first running rail 11 is located above the cargo ship 5 arriving at the port, and the other end is located above one side of the automatic roller conveyor system 2.

[0036] The first automatic control system is used to control the first crane to move along the first running rail 11 to above the cargo ship 5 after the cargo ship 5 arrives at the port, then control the first crane to lift the container 6 on the cargo ship 5, and after lifting the container 6, control the first crane to move along the first running rail 11 to the side of the automatic roller conveyor system 2, that is, above the automatic roller conveyor system 2, and finally control the first crane to lower the container 6 onto the automatic roller conveyor system 2.

[0038] The second automatic control system is used to start the roller conveyor after the first crane lowers the container 6 onto the roller conveyor of the automatic roller conveyor system 2, so that the container 6 moves on the roller conveyor, and when the container 6 moves along the roller conveyor to the first preset position, the roller conveyor is paused to wait for the empty rail system 3 to grab the container 6 from the first preset position.

[0039] Alternatively, see Figure 1 The roller is a circular roller that is connected end to end, and the first preset position is a position on the roller that overlaps with the empty rail in the alignment direction.

[0040] Optionally, a lateral fixer is also provided on the roller conveyor, and the second automatic control system is also used to control the lateral fixer. When the first crane lowers the container 6 onto the automatic roller conveyor system 2, the container 6 on the roller conveyor is fixed by the lateral fixer.

[0041] The empty rail system 3 includes an empty rail, a trolley 31 running on the empty rail, a sling arranged on the trolley 31, and a third automatic control system for controlling the sling and the trolley 31. The height of the empty rail is higher than that of the roller conveyor.

[0042] The third automatic control system is used to control the trolley 31 to run along the empty rail to above the corresponding first preset position when the container 6 moves to the first preset position on the roller conveyor, and then control the spreader on the trolley 31 to grab the container 6 on the first preset position, and then control the trolley 31 to run along the empty rail to the second preset position. After reaching the second preset position, the spreader is controlled to lower the container 6 to the container yard system 4 below the second preset position.

[0043] Optionally, the empty rail is a circular empty rail connected end to end, and most of the empty rails have multiple branches on one side of the container yard system 4 according to the container yard system 4.

[0044] The container yard system 4 includes a yard, a second running rail 42 arranged above the yard, a second crane 41 installed on the second running rail, and a fourth automatic control system for controlling the second crane 41;

[0045] The fourth automatic control system is used to control the second crane 41 to move along the second running rail 42 to above the container 6 based on the position information of the container 6 lowered to the container yard system 4 after the container 6 is lowered to the container yard system 4, and control the second crane 41 to lift the container 6 below, and after lifting the container 6, control the second crane 41 to move to a designated position along the second running rail 42, and then lower the container 6 to the yard to complete the stacking of the container 6.

[0046] There are multiple second cranes 41 and multiple second running rails 42, corresponding to multiple branches of the empty rails set above the container yard system 4. The first crane and the second crane 41 can be container gantry cranes.

[0048] The process flow of a container terminal collection and distribution system provided by an embodiment of the present invention is as follows:

[0049] (1) After the container ship arrives at the port, the docking information is transmitted to the port automation inter-control system, and the port automation inter-control system sends instructions to the first automatic control system of the container loading and unloading quay crane system 1. The first crane of the container loading and unloading quay crane system 1 moves to the designated position, grabs the container 6 on the ship through the lifting device, and places it on the automatic roller conveyor system 2.

[0050] (2) After the container 6 is placed on the automatic roller conveyor system 2, the side fixer on the automatic roller conveyor system 2 fixes the container 6, and the automatic roller conveyor system 2 is started to transfer the container 6 from the container loading and unloading quay crane system 1 to the air rail system 3 through the roller.

[0051] (3) After the lifting device of the aerial rail system 3 grabs the container 6, it lifts the container 6 and moves the container 6 to the rear yard through the trolley 31, and then lowers the container 6 and places it on the ground of the yard.

[0052] (4) After receiving the location information of container 6, the container gantry crane at the rear container 6 yard moves to the corresponding position. After lifting container 6, the container gantry crane trolley moves along the second running rail 42 to the position where container 6 needs to be stacked, and stacks container 6 in the yard.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
