Description

Technical Field

[0001] The utility model belongs to the technical field of port engineering, and relates to a long approach bridge type container terminal transportation system which integrates an aerial rail and a straddle type monorail. Background Art

[0002] In the existing long-bridge container terminal transport system, the front container terminal is connected to the land-based container yard via a long approach bridge. The approach bridge is generally longer than 300 meters, designed with 6 to 10 lanes in both directions and a width of approximately 25 to 40 meters. Horizontal container transport vehicles, such as AGVs (Automated Guided Vehicles) and IGVs (Intelligent Guided Vehicles), travel back and forth between the front terminal and the rear yard over the long approach bridge, transporting containers horizontally.

[0003] The above arrangement utilizes a single horizontal transport system with a wide approach bridge. Container transport vehicles must travel back and forth over the long approach bridge section, occupying a significant portion of their non-loading and unloading time and significantly increasing the number of horizontal transport equipment required. The approach bridge's base must pass through a flood (tidal) dike, necessitating the installation of gates appropriate to the width of the approach bridge. While this method can transport containers from the rear yard to the front dock, it suffers from low efficiency, a large number of lanes, and complex traffic organization, resulting in high construction and operating costs.

[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) dike, thereby improving transportation efficiency and reducing project costs. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes a method of applying the fusion technology of sky rail and straddle monorail to the long approach bridge type container terminal transportation system, mainly using the fusion technology of sky rail + straddle monorail to replace the horizontal container transport vehicle to realize the container transportation between the rear land yard and the front terminal.

[0006] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0009] The lower part of the trestle pier 15 can be supported by multiple trestle lower pile foundations 16; the trestle piers 15 are arranged at equal intervals and overlapped with each other through the trestle bridge deck 19 to form a continuous and complete bridge deck, and the container horizontal transport vehicle 12 can travel on the trestle bridge deck 19.

[0010] The bottom of the trestle column 13 is fixed at the center of the trestle pier 15, and the top of the trestle beam 14 is fixed; the trestle longitudinal beam 18 is overlapped between two adjacent trestle beams 14 to form a complete track beam.

[0011] The upper and lower parts of the trestle longitudinal beam 18 are respectively provided with two parallel tracks, and the upper and lower parts of the trestle cross beam 14 are also provided with two parallel tracks. The track positions on the trestle longitudinal beam 18 and the trestle cross beam 14 are connected with each other and docked to form a complete track. The two parallel tracks are respectively located on both sides of the trestle column 13; among them, the track on the upper surface is used to install the straddle-type monorail trolley 10, and the track on the lower surface is used to install the suspended sky-rail trolley 11, so as to construct a straddle-type monorail and suspended sky-rail integrated trestle 2.

[0012] The container yard 3 is located on land, and the land-based transshipment area 8 realizes the interactive loading and unloading operations between land-based containers and the straddle-type monorail and suspended sky-rail integrated trestle 2; the container loading and unloading bridge 9 is located on the container terminal 1; the straddle-type monorail and suspended sky-rail integrated trestle 2 is arranged between the land-based transshipment area 8 and the container terminal 1, one end of the straddle-type monorail and suspended sky-rail integrated trestle 2 is connected to the land-based transshipment area 8, and the other end of the straddle-type monorail and suspended sky-rail integrated trestle 2 is connected to the container terminal 1, and the straddle-type monorail and suspended sky-rail integrated trestle 2 is arranged under the inner span of the container loading and unloading bridge 9.

[0013] The container 17 is grabbed from the straddle-type monorail trolley 10 by the container loading and unloading bridge 9, or the container 17 is lifted and placed on the straddle-type monorail trolley 10; the container 17 unloaded from the suspended sky-rail trolley 11 is received by the lifting receiving trolley provided on the container terminal 1, or the container 17 is grabbed by the suspended sky-rail trolley 11; the container horizontal transport vehicle 12 and the container loading and unloading bridge 9 can be used for interactive loading and unloading operations; a return line 6 is provided at the terminal end of the straddle-type monorail and suspended sky-rail integrated trestle 2 near the container terminal 1; the straddle-type monorail trolley 10 and the suspended sky-rail trolley 11 complete the track change and travel in reverse via the return line 6, and repeat the above operation process again; the unloaded container 17 is transported to the land transshipment area 8 by three methods of the straddle-type monorail trolley 10, the suspended sky-rail trolley 11 and the container horizontal transport vehicle 12, and enters the container yard 3 after transshipment, completing a ship loading and unloading cycle operation.

[0014] The width of the straddle-type monorail and suspended sky-rail integrated trestle 2 is 9 to 12 meters.

[0015] The number of the pile foundations 16 of each group of trestle lower parts can be set according to geological conditions, etc., and can also be replaced by structures such as gravity piers.

[0016] If multiple docks are arranged in a row, a straddle-type monorail and a suspended sky-rail integrated trestle 2 can be set at each end of the dock to realize a large circulation scheme of entering at one end and exiting at the other end, replacing the arrangement of the return line 6.

DETAILED DESCRIPTION

[0027] The following further illustrates the specific implementation of the transportation system utility model in combination with the accompanying drawings and technical solutions.

[0028] The utility model discloses a long approach bridge type container terminal transportation system integrating an aerial rail and a straddle type monorail, which mainly comprises a container terminal 1, a straddle type monorail and a suspended aerial rail integrated trestle 2 and a container yard 3.

[0029] like Figure 1 As shown, the general layout is as follows: the container yard 3 at the rear is connected to the container terminal 1 in front through a narrow trestle (width of about 9 to 12 meters, with 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 project needs. 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.

[0030] like Figure 2 and Figure 3As shown, the cross-section of the trestle is arranged 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 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 above the straddle-type monorail transport trolley 10 are placed containers 17; on both sides below the upper longitudinal beam 18 of the trestle are suspended sky rail trolleys 11, and below the suspended sky rail trolley 11 are locked containers 17; the trestle bridge deck 19 between the trestle piers 15 serves 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 integrated monorail and suspended skyrail trestle 2 includes a trestle lower pile foundation 16, trestle piers 15, trestle columns 13, trestle crossbeams 14, trestle longitudinal beams 18, a trestle deck 19, a monorail trolley 10, a suspended skyrail trolley 11, and a container horizontal transport vehicle 12. The trestle lower pile foundations 16 are multiple groups, their bottoms fixed in the sea. A horizontally arranged trestle pier 15 is mounted on top of each group of trestle lower pile foundations 16. There are multiple trestle piers 15 arranged at equal intervals. The trestle deck 19 is horizontally arranged and disposed between two adjacent trestle piers 15 to form a continuous and complete deck. The container horizontal transport vehicle 12 is arranged on the trestle deck 19 and transports containers on it. The bottom of the trestle column 13 is fixed at the center position of the upper surface of the trestle pier 15, and the top of the trestle column 13 is fixed at the center position of the lower surface of the horizontally arranged trestle crossbeam 14; the trestle longitudinal beam 18 is arranged horizontally and installed between two connected trestle crossbeams 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 crossbeam 14. The track positions on the trestle longitudinal beam 18 and the trestle crossbeam 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; among them, the upper track is used to install the straddle-type monorail trolley 10, and the lower track is used to install the suspended sky rail trolley 11, realizing the integrated transportation of the straddle-type monorail and the suspended sky rail.

[0032] The loading and unloading process is designed to operate in a one-way clockwise (or counterclockwise) loop across all three levels. Trolley operation intervals are determined based on traffic simulations. The dispatching system implements intelligent algorithm control based on real-time positioning monitoring of the trolleys and predetermined operational schedules. The container loading and unloading bridge 9 grabs the container 17 from the trolley to complete the loading operation. The empty trolley then reverses along the designated reversal line 6, reloading the unloaded container at the terminal's front operating area and transporting it to the rear container yard 3, repeating the cycle.

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

[0034] In the land transshipment area, loaded containers 17 are transported along the straddle monorail and suspended sky rail integrated trestle 2 by means of a straddle monorail trolley 10, a suspended sky rail 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 sky rail 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 lifted from the container ship 5 and placed on the straddle monorail trolley 10 by the container loading and unloading bridge 9, and the suspended empty rail trolley 11 is lifted and locked by the lifting trolley and returned to the land transfer area 8 along the straddle monorail and suspended empty rail integrated trestle 2, forming a complete cycle.

[0035] All containers 17 on the container ship 5 are loaded and unloaded via the container bridge 9. During loading, the container bridge 9 directly grabs the containers 17 on the straddle-type monorail trolley 10 below; or it uses a lifting transfer trolley to lock and hook the containers 17 to the suspended overhead rail trolley 11. Alternatively, after being transported to the container terminal 1 by a container horizontal transporter 12, the container bridge 9 grabs the containers 17 on the container horizontal transporter 12. During unloading, the container bridge 9 grabs all containers 17 from the container ship 5 and places them on the straddle-type monorail trolley 10, container horizontal transporter 12, and lifting platform. The straddle-type monorail trolley 10 and container horizontal transporter 12 are directly transported, while the containers 17 on the lifting platform are grabbed by a manipulator and transferred to the suspended overhead rail trolley 11 for transportation.

[0036] In addition, the number of straddle-type monorail and suspended skyrail integrated trestle 2 can be increased according to the number of corresponding container terminals 1. For example, if there are multiple container terminals 1 arranged in a continuous manner, straddle-type monorail and suspended skyrail integrated trestle 2 can be installed at both ends of the terminal to connect with the land. The straddle-type monorail trolley 10 and suspended skyrail trolley 11 enter from one end of the container terminal 1 via the straddle-type monorail and suspended skyrail integrated trestle 2 and exit from the other end of the container terminal 1, forming a large-circuit scheduling method.

[0037] Furthermore, as an example, the pier structure is not limited to the pier pile foundation 16. For example, a gravity caisson or other pier-type solution may be used instead. While the example is for a single berth, if multiple berths are arranged in a continuous area, a straddle-type monorail and a suspended skyrail integrated pier may be installed at each end of the berth to achieve a large-scale loop with one end entering and the other exiting, replacing the switchback arrangement.

[0038] The utility model is a long-approach bridge container terminal transportation system that integrates an aerial rail and a straddle-type monorail. It is an improvement on the conventional horizontal transportation system of container terminals. It adopts 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 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, reducing the vertical lowering and lifting distance of the container loading and unloading bridge hoist, thereby improving its loading and unloading efficiency. The system of the utility model is suitable for the separate arrangement of the rear yard and the front container terminal, which are connected in the middle by a trestle integrating 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 the reciprocating shuttle transportation between the front and rear areas.
