[0002] In the existing long approach bridge container terminal transportation system layout, the front container terminal is connected to the land container yard through a long approach bridge. The approach bridge is generally longer than 300m, designed with 6 to 10 lanes in both directions, and is about 25 to 40m wide. Container horizontal transport vehicles or AGVs (Automated Guided Vehicles) and IGVs (Intelligent Guided Vehicles) travel back and forth between the front terminal and the rear yard through the long approach bridge to achieve horizontal transportation of containers.

[0003] The above arrangement system adopts a single horizontal transport, the approach bridge is wide, and the horizontal container transport vehicles need to complete the long approach bridge section to travel back and forth, which takes up a lot of their non-loading and unloading operation time, resulting in a significant increase in the number of horizontal transport equipment. The root of the approach bridge needs to cross the flood (tide) dike, and gates corresponding to the width of the approach bridge need to be added. Although this mode of transportation can complete the transportation of containers from the rear yard to the front wharf, the transportation efficiency is low, the number of lanes is large, the traffic organization is difficult, and the project cost and operation cost are high.

[0004] Therefore, it is necessary to develop a new transportation system that can achieve the same function by reducing the width of the approach bridge, reducing the number of horizontal container trucks, and crossing the flood (tide) embankment, thereby improving transportation efficiency and reducing project costs.

DETAILED DESCRIPTION

[0027] The specific implementation of the transportation system invention is further described below in conjunction with the accompanying drawings and technical solutions.

[0028] The long approach bridge type container terminal transportation system integrating sky rail and straddle type monorail of the present invention mainly comprises a container terminal 1, a straddle type monorail and suspended sky rail integrated trestle 2 and a container yard 3.

[0029] like Figure 1 As shown, the general plan layout is as follows: the container yard 3 at the rear is connected to the container terminal 1 in the front through a narrow trestle (width of about 9 to 12 m, a straddle-type monorail and suspended skyrail integrated trestle 2); the length of the straddle-type monorail and suspended skyrail integrated trestle 2 is selected according to the needs of the project; combined with the terminal axis and the angle of the trestle, a smaller turning radius can be set for the trestle in the front terminal area to connect to the terminal axis direction.

[0030] like Figure 2 and Figure 3As shown, the cross-section layout of the trestle is as follows: the lower part adopts the lower pile foundation 16 of the trestle, and the structural type of the trestle column 13 plus the trestle cross beam 14 is set above the trestle pier 15. The net height from the trestle pier 15 to the upper trestle cross beam 14 meets the use requirements, and it is divided into three layers from top to bottom: above the upper longitudinal beam 18 of the trestle is a two-line straddle-type monorail transport trolley 10, and a container 17 is placed above the straddle-type monorail transport trolley 10; suspended sky-rail trolleys 11 are set on both sides below the upper longitudinal beam 18 of the trestle, and containers 17 are locked under the suspended sky-rail trolley 11; the trestle bridge deck 19 between the trestle piers 15 is used as a passage for two-way horizontal container transport vehicles 12 (to meet the transportation of extra-long containers, etc.), and is also used as a patrol fire lane. The details are as follows:

[0031] The straddle-type monorail and suspended sky rail integrated trestle 2 comprises a trestle lower pile foundation 16, a trestle pier 15, a trestle column 13, a trestle cross beam 14, a trestle longitudinal beam 18, a trestle bridge deck 19, a straddle-type monorail trolley 10, a suspended sky rail trolley 11 and a container horizontal transport vehicle 12. There are multiple groups of trestle lower pile foundations 16, the bottom of which is fixed in the sea, and a horizontally arranged trestle pier 15 is installed on the top of each group of trestle lower pile foundations 16; there are multiple trestle piers 15, which are arranged at equal intervals, and the trestle bridge deck 19 is arranged horizontally and set between two adjacent trestle piers 15 to form a continuous and complete bridge deck, and the container horizontal transport vehicle 12 is arranged on the trestle bridge deck 19 to transport on the trestle bridge deck 19. The bottom of the trestle column 13 is fixed at the center of the upper surface of the trestle pier 15, and the top of the trestle column 13 is fixed at the center of the lower surface of the horizontally arranged trestle cross beam 14; the trestle longitudinal beam 18 is arranged horizontally and installed between two connected trestle cross beams 14 to form a complete track. Two parallel tracks are provided above and below the trestle longitudinal beam 18, and two parallel tracks are provided above and below the trestle cross beam 14. The track positions on the trestle longitudinal beam 18 and the trestle cross beam 14 are connected to each other and docked to form two complete tracks. The two parallel tracks are respectively located on both sides of the trestle column 13; wherein, the upper track is used to install the straddle-type monorail trolley 10, and the lower track is used to install the suspended empty rail trolley 11, so as to realize the integrated transportation of the straddle-type monorail and the suspended empty rail.

[0032] Loading and unloading process setting: The upper, middle and lower layers all adopt a one-way clockwise (or counterclockwise) circular transportation mode. The trolley operation interval can be comprehensively determined based on traffic simulation, and the dispatching system performs intelligent algorithm control based on the real-time positioning monitoring of the trolley and the predetermined operation plan. The container loading and unloading bridge 9 grabs the container 17 from the trolley to complete the loading operation. The empty trolley reverses along the set return line 6 and can load the unloading container again in the front operating area of ​​the terminal and transport it to the rear container yard 3, which is repeated over and over again to achieve a cycle operation.

[0033] like Figure 4 As shown, the specific operation process of the system of the present invention is as follows:

[0034] In the land transshipment area, containers 17 are loaded and transported along the straddle monorail and suspended skyrail integrated trestle 2 by means of a straddle monorail trolley 10, a suspended skyrail trolley 11 and a container horizontal transport vehicle 12. The straddle monorail trolley 10 is arranged above the upper longitudinal beam 18 of the trestle, and the skyrail trolley 11 is suspended below the upper longitudinal beam 18 of the trestle. The upper part of the trestle column 13 is connected to the trestle cross beam 14, and the lower part is connected to the trestle pier 15. The lower part of the trestle pier 15 adopts a trestle pile foundation 16 as the lower foundation of the trestle pier 15. The container 17 is transported to the front container terminal 1 by the straddle-type monorail and suspended sky-rail integrated trestle 2, and stops at the corresponding container loading and unloading bridge 9. The straddle-type monorail trolley 10 can directly lift the container 17 onto the container ship 5 by the container loading and unloading bridge 9, and the container 17 locked by the suspended sky-rail trolley 11 is carried by the lifting and receiving trolley, and then the loading and unloading bridge 9 performs the grabbing operation. The straddle-type monorail trolley 10 and the suspended sky-rail trolley 11 drive empty to the end of the terminal, realize the reverse lane change operation through the reversing line 6, and stop at the corresponding container loading and unloading bridge 9 again. The container loading and unloading bridge 9 lifts the container 17 from the container ship 5 and places it on the straddle-type monorail trolley 10, and the suspended sky-rail trolley 11 is lifted and locked by the lifting and receiving trolley, and returns to the land transfer area 8 along the straddle-type monorail and suspended sky-rail integrated trestle 2, forming a complete cycle.

[0035] Among them, all containers 17 on the container ship 5 are loaded and unloaded through the container loading and unloading bridge 9. When loading, the container loading and unloading bridge 9 directly grabs the container 17 on the straddle-type monorail trolley 10 below; or through the lifting and receiving trolley transition, the suspended empty rail trolley 11 realizes the locking operation of the container 17, or after being transported to the container terminal 1 by the container horizontal transport vehicle 12, the container loading and unloading bridge 9 grabs the container 17 on the container horizontal transport vehicle 12. When unloading, the container loading and unloading bridge 9 grabs all containers 17 from the container ship 5, and then places them on the straddle-type monorail trolley 10, the container horizontal transport vehicle 12 and the lifting platform. The straddle-type monorail trolley 10 and the container horizontal transport vehicle 12 are directly transported, and the container 17 on the lifting platform is grabbed by the manipulator to the suspended empty rail trolley 11 for transportation.

[0036] In addition, the number of straddle-type monorail and suspended sky-rail integrated trestle 2 can be increased according to the number of corresponding container terminals 1. For example, when the container terminals 1 are arranged in a plurality of continuous arrangements, straddle-type monorail and suspended sky-rail integrated trestle 2 can be respectively arranged at both ends of the terminal to connect with the land, and the straddle-type monorail trolley 10 and suspended sky-rail trolley 11 enter from one end of the container terminal 1 through the straddle-type monorail and suspended sky-rail integrated trestle 2 and exit from the other end of the container terminal 1, forming a large-circulation dispatching method.

[0037] In addition, as an example, the structural type of the pier is not limited to the pier pile foundation 16, for example, a pier type solution such as a gravity caisson can be used as an alternative. At the same time, the example is a single berth. If multiple piers are arranged in a row, a straddle-type monorail and a suspended sky rail integrated pier can be set at both ends of the pier to realize a large circulation solution of one end in and one end out, replacing the layout of the return line.

[0038] The long-approach bridge container terminal transportation system that integrates an aerial rail and a straddle-type monorail of the present invention is an improvement on the conventional horizontal transportation system of container terminals. It uses a three-dimensional low-altitude method to realize multi-line container rail transportation, thereby improving its transportation efficiency; it can directly cross the flood (tide) dike without affecting the flow of flood water; it can realize the direct interactive operation of the straddle-type monorail trolley and the suspended aerial rail trolley with the container quay crane, reduce the vertical lowering and lifting distance of the container loading and unloading bridge hoist, and improve its loading and unloading efficiency. The system of the present invention is suitable for the separate arrangement of the rear yard and the front container terminal, which are connected in the middle by a trestle that integrates the straddle-type monorail and the suspended aerial rail technology. The containers use the transport trolleys of the straddle-type monorail and the suspended aerial rail to realize reciprocating shuttle transportation between the front and rear areas.
