Description

Overhead rail transport system for cargo transportation

Technical Field

The invention relates to the technical field of cargo transportation, in particular to an overhead rail transportation system for cargo transportation.

Background

With the rapid development of economy, the logistics demands among various areas are continuously increased, and rail transit is always the preferred mode of cargo transportation due to the strong transportation capacity and low transportation cost.

For some areas of complex terrain, it can take a significant amount of time and cost to lay the ground track. In addition, the laying of ground tracks may present problems of excessive occupation and environmental damage. Therefore, air rail cargo transportation systems have been developed for the purpose of reducing costs, compressing construction cycles, reducing floor space, reducing environmental damage, improving the adaptation of the rail to complex terrain, and the like.

The existing empty rail transportation mode adopts a suspension type empty rail transportation system to transport, the container is suspended below the rail, and the mobile equipment enables the container to be transported along the rail. However, with such suspended empty rail transportation systems, sufficient space needs to be reserved under the rail structure in order to suspend the container, which results in that the height of the empty rail cannot be lowered, and the construction height of the entire empty rail is high.

The existing suspension type empty rail transportation mode is not beneficial to hoisting the container, and a specially designed moving platform is required to move the container below the rail structure, and then the container is hoisted and suspended. In addition, there are limitations to the objects that can be transported by the overhead rail transport system, which are generally available only for transporting standard containers, and if the container for loading the cargo is not standard, or if the container is an open-top container, it is not suitable for overhead transport. In addition, due to the strength of the suspension device, the conventional suspended empty rail transportation mode is not suitable for transporting the goods which are too heavy.

On the other hand, in existing cargo distribution centers, various types of switches are arranged to effect transfer of transport vehicles between different tracks, however, switching efficiency is not high in the manner of switching tracks with existing switches, and overall operating efficiency of the distribution center may be affected. In addition, some existing transportation systems utilize large diameter, closed endless tracks to effect transfer of transportation vehicles between different tracks, however, such endless tracks take up excessive floor space.

Therefore, it is desirable to improve the existing overhead transport systems for cargo transportation and to provide a transport system that is efficient in transportation, inexpensive in construction, flexible in construction, wide in applicable transport object range, and more flexible in use.

Detailed Description

The present invention will be further described with reference to specific embodiments and drawings, in which more details are set forth in the following description in order to provide a thorough understanding of the present invention, but it will be apparent that the present invention can be embodied in many other forms than described herein, and that those skilled in the art may make similar generalizations and deductions depending on the actual application without departing from the spirit of the present invention, and therefore should not be construed to limit the scope of the present invention in terms of the content of this specific embodiment.

In this disclosure, unless otherwise indicated, the terms "top/upper" and "bottom/lower" and like directional terms refer to the orientation of the various components in the conventional installed state of an overhead rail transport system. The term "lateral" generally refers to a lateral direction relative to the length or main extension of the elevated track, or a direction transverse thereto, including but not limited to a vertical direction. The azimuth term "vertical direction" as used herein is defined as a direction substantially along the direction of gravity.

In the present disclosure, the term "buffer" refers to an area for storing a transport object such as a container. It should be noted that the "cache" is not directly related to the time of storage, and the transport object may be stored in the "cache" temporarily (for example, within minutes, tens of minutes), or may be stored in the "cache" for a longer period of time (for example, days, weeks, months).

Furthermore, the terms "first" and "second" herein do not denote any order of preference, nor do they denote any order of preference, unless otherwise specified, but rather the terms first and second are used interchangeably without affecting the description of the embodiments.

Fig. 1 shows an example arrangement of an elevated rail system for the transportation of goods according to the invention. The overhead rail transit system mainly includes two terminal areas 1 and a transit area 2 connecting the two terminal areas 1. The overhead rail transport system uses an overhead rail design, the overhead rail is laid overhead away from the ground by a support device, and the truck 200 travels over the overhead rail. In the present overhead rail transport system, the transport zone includes overhead rails laid in pairs.

As shown in fig. 2, the object 600 being transported by the transport system is a container, such as a 20-or 40-gauge container, but it should be understood that the object 600 may be a cargo directly loaded on the truck 200, a cargo-loaded or unloaded pallet, or other containment device suitable for the truck-supported transport. The transportation object includes, but is not limited to, a box shape (e.g., a container), and any transportation object may be used as long as it is shaped, sized, and shaped to be transported by a truck. In addition, the container shown in fig. 2 is closed, but it should be understood that the receiving means as the object of transportation may also be open-topped.

The terminal areas 1 are typically arranged in various distribution centers or distribution network hubs, such as coastal ports, inland ports, airports, logistics parks, etc., while the transport area 2 connects at least two different terminal areas 1 to achieve efficient and quick transport of goods between distribution centers or distribution network hubs.

Each termination area 1 comprises an empty working area 11 and a translational track transfer area 12. The overhead rail work area 11 is arranged to perform an inter-working between the overhead rail and the ground of the transport object 600, where "inter-working" generally refers to operations of transferring the transport object from the overhead rail to the ground buffer or the ground work area, and transferring from the ground buffer or the ground work area to the overhead rail for carrying, lifting, shifting, etc. The translational track-change area is arranged to effect transfer of the truck 200 between two overhead tracks, i.e. transfer of the truck from one track to the other and from the other track to the one track.

Specifically, as shown in fig. 1, the transportation area in the overhead rail transportation system according to the preferred embodiment includes overhead rails laid in pairs, that is, the overhead rails include a first overhead transportation rail 201 and a second overhead transportation rail 202, and while one row of the trucks travels from the terminal area a to the terminal area B along the first overhead transportation rail, another row of the trucks can travel from the terminal area B to the terminal area a along the second overhead transportation rail.

As shown in fig. 1, two overhead transport rails 201, 202 are supported by a plurality of supporting means 203, and the two overhead transport rails 201, 202 are laid generally in parallel, so that one supporting means 203 supports both overhead transport rails 201, 202 at the same time. Preferably, the overhead transport rails 201, 202 comprise a plurality of rail steel modules 100 as shown in fig. 5 and steel structural support means 203, the support means 203 being supported at opposite ends of adjacent two sections of rail steel modules 100, one support means 203 supporting four of the two opposite ends of four sections of rail steel modules 100 for an overhead transport rail arranged in pairs in parallel.

Preferably, the support device 203 is a steel structure comprising a round steel pipe 203b and a steel structural support platform 203a, the ends of the rail steel modules 100 being placed on the support surface of the support platform 203 a. The use of round steel tube 203b for support 203 advantageously reduces wind drag and thus reduces the negative impact of wind on structural stability.

Fig. 5 shows a perspective view of a single rail steel module 100 according to a preferred embodiment of the present invention. Preferably, the individual rail steel modules 100 are generally trapezoidal in shape with a wide top and a narrow bottom when viewed from the side, each rail steel module 100 having a pair of top rail beams 101, a pair of bottom support beams 102, and a plurality of stiffening beams 103. The rails 105 carrying the wheels of the truck 200 are laid on the top rail beam 101. Each of the pair of bottom support beams 102 is located below a corresponding section of the top rail beam 101, and supports the top rail beam 101. Each section of bottom support beam 102 includes a bottom horizontal beam 102a with end beams 102b extending obliquely upward and outward on either side. In one rail steel module 100, the length of the bottom horizontal beam 102a is less than the length of the top rail beam 101. In addition, a plurality of reinforcement beams 103 extend between the top rail beam 101 and between the top rail beam 101 and the bottom support beam 102, respectively.

For a length of rail steel modules 100, the beams form a reliable structural connection, such as by welding, and the specifications and materials of the individual beams and the number of reinforcing beams can be freely selected according to the design requirements of the overhead rail transport system. The formed length of track steel module 100 should support at least a complete length of truck 200, preferably the length of track steel module 100 is greater than the sum of the lengths of at least two sections of truck 200 to accommodate multiple ganged trucks.

Each rail steel module 100 may be prefabricated in a factory and then transported to the installation site of the rail transportation system where modular assembly of the overhead rail is performed.

When the end of the rail steel module 100 is mounted on the supporting means 203, most of the body of the rail steel module 100 is located below the supporting surface of the supporting means 203 in the vertical direction, that is, the bottom supporting beam 102 serving as supporting reinforcement is arranged to extend downward, and the height of the bottom horizontal beam 102a is lower than the height of the supporting surface at the supporting means 203. More preferably, as shown in fig. 3, the horizontal height of the bottom horizontal beam 102a is positioned below the support platform 203a of the support device 203, thereby forming a submerged elevated rail support structure that significantly reduces the overhead height of the elevated rail.

The design of the overhead transport track according to the system of the invention facilitates the construction of transport lines on complex terrain. On the other hand, the system of the present invention advantageously reduces the overhead height of overhead rails compared to existing overhead rail transport systems. For the same design requirements, the overhead height of the upper supported overhead rail according to the invention can be about 5 meters lower than the overhead height of the middle rail of the existing suspended overhead rail transport system. Furthermore, it should be understood that if the terrain is limited to the construction area, a portion of the two overhead transport tracks may also be laid non-parallel in the transport area.

Fig. 2 shows a schematic diagram of a termination area 1 according to a preferred embodiment of the invention. Preferably, the terminal area 1 is provided with a maintenance area 15 for performing maintenance work on the truck, in addition to the empty working area 11 and the translational track transfer area 12. Typically, each terminal area 1 is provided with a service area 15, but in some specific use cases it is also possible to provide only one terminal area 1 with a service area 16.

As shown in fig. 1, one end of the transport section 2 is connected to one terminal section 1. For the transport zone 2 having the paired overhead transport rails 201, 202, the overhead working zone 11 of the terminal zone 1 has two overhead working rails, respectively: a first overhead working rail 111 and a second overhead working rail 112, the two overhead working rails 111, 112 being arranged in parallel. In a preferred embodiment of the present invention, the aerial rail working area 11 of the terminal area 1 is connected to the transport area 2, i.e. the aerial rail working rails 111, 112 of the aerial rail working area 11 of the terminal area 1 are directly connected to the aerial transport rails of the transport area 2 and the aerial rail working area 11 is connected to the translatory rail change area 12, i.e. the other end of at least one aerial rail working rail 111 or 112 of the aerial rail working area 11 is directly connected to at least one aerial movable rail 121 or 122 of the translatory rail change area 12. The maintenance area 15 is then arranged at a position of the terminal area 1 furthest away from the transport area 1, i.e. the maintenance area 15 is arranged at a position of the furthest end of the entire transport system. In this way, the truck 200 coming from the transport zone 2 first enters the empty working zone 11, then enters the translational derailment zone 12, and finally enters the maintenance zone 15.

The specific arrangement of the termination region 1 is not limited to the above-described embodiment. In other alternative embodiments, the positions of the blank track service zone 11 and the translatory track change zone 12 may be replaced, that is to say, in the direction from the transport zone 2 to the terminal zone 1, one end of the transport zone 2 is first connected to the translatory track change zone 12, the blank track service zone 11 being arranged downstream of the translatory track change zone 12, while the maintenance zone 15 is still arranged in the most distal position of the entire transport system.

In the terminal area 1, the length of the overhead working rail in the overhead working area 11 can be set according to the requirements of the installation place to improve the working efficiency of the terminal area 1.

In other alternative embodiments, the terminal area 1 may further comprise a plurality of translational track-change areas 12, for example, two translational track-change areas 12, one being arranged upstream of the aerial track work area 11 and the other being arranged downstream of the aerial track work area 11, to accommodate different workflow requirements.

Fig. 3 shows a schematic perspective view of a translational track pad 12 according to a preferred embodiment of the invention. In a preferred embodiment, the translational track section 12 includes first and second overhead movable rails 121, 122 arranged in parallel, and translational support devices 123 arranged at both ends of the overhead movable rails. The two overhead movable rails 121, 122 are each formed by two sections of rail steel modules 100, the two sections of rail steel modules 100 being translatable on the bearing surfaces of the translation bearing 123. Typically, the translation of both ends of the two rail steel modules 100 is performed simultaneously. The track steel module in the translational track change 12 may employ the track steel module 100 shown in fig. 5.

The translational support 123 of the translational track section 12 is wider in a direction perpendicular to the extension of the overhead track than the support 203 of the transport section 2, as shown in fig. 3, thereby providing lateral translational space for the two overhead movable tracks 121, 122.

To achieve lateral translation of the overhead movable rails 121, 122, the translating track section 12 includes a translating guide rail, a translating carriage, and a drive for driving the translating carriage to reciprocate relative to the translating guide rail. The driving means is for example a motor. The translatory guide rail is arranged on the support surface of the translatory support 123 with its laying direction substantially perpendicular to the extension direction of the two overhead movable rails 121, 122. In order to achieve a reliable translational movement of the overhead movable rails 121, 122 with the carrier 200 mounted thereon, the driving means provided at both ends of the overhead movable rails 121, 122 should be capable of synchronously moving the translational carriages along the translational guide rails, i.e. the translational carriages at both ends are capable of moving in the same direction and speed.

As shown in fig. 3, overhead movable rail 122 is proximal to the illustration and overhead movable rail 121 is distal to the illustration. In the initial state, the two parallel overhead movable rails 121, 122 in the translational track change region 12 are respectively abutted with the two overhead working rails 111, 112 of the adjacent empty track working region 11, and as the driving device drives the translational carriage to translate laterally along the translational guide rail in the proximal direction, the overhead movable rails 121, 122 enter a translational state as shown in fig. 3, wherein the overhead movable rails 121, 122 move in the proximal direction, such that the distal overhead movable rail 121 is abutted with the proximal overhead working rail 112, and the proximal overhead movable rail 122 and the distal working rail 111 are in a disconnected state. The overhead movable rails 121, 122 are capable of being shifted between an initial state and a translated state according to an instruction of the control apparatus, so that the truck 200 can be transferred onto the corresponding overhead working rail and thus into the corresponding overhead transport rail.

As shown in fig. 3, the support platform of the translation support 123 of the translation track 12 extends laterally only in the proximal direction, widening providing lateral translation space for the overhead movable rails 121, 122. It should be appreciated that in other alternative embodiments, the support platform of the translation support 123 of the translation track 12 may extend in both lateral directions, allowing both the distal and proximal side of the two overhead movable rails 121, 122 to translate laterally, thereby enabling a more flexible and efficient track change operation with respect to the different work rails 111, 112, respectively.

In other alternative embodiments, the translating derailment region 12 may include only a single segment of overhead movable track (i.e., the single segment track steel module 100) upon which the truck 200 stops, with lateral movement of the overhead movable track effecting transfer of the truck 200 between the pair of overhead working tracks 111, 112 for entry of the truck into the respective overhead transport tracks 201, 202.

Fig. 4 shows a schematic plan view of an overhead working area 11 for implementing an inter-working of an overhead working track with a ground area in the termination area 1 according to the present invention.

As shown in fig. 3 and 4, the overhead working area 11 is provided with a portal crane 500, one, preferably a plurality, for carrying and lifting a transport object 600 such as a container, so as to implement an interactive operation between an overhead track and the ground. The gate-type lifting device 500 is arranged laterally across the first and second overhead working rails 111, 112 of the overhead working area 11 and is movable in the extension direction of the overhead working rails 111, 112. It should be understood that other lifting devices for handling, lifting and moving the transport object may be provided in the overhead working area 11, and that commonly used lifting devices also include cranes, bridge cranes, tower cranes, etc.

In addition, the terminal area 11 further includes a ground working area 13 and a ground buffering area 14. The transport object 600 is carried from the overhead working track to the ground working area 13 or the ground buffer area 14 or vice versa according to an instruction of a control device in the system, thereby performing an interactive operation rapidly. In addition, the system may also include a ground handling apparatus, such as a head lift 400, for transferring the transport object 600 between the ground buffer 14 and the ground transport cart 300.

The overhead working rails 111, 112 constituting the overhead working zone 11 may employ the rail steel module 100 shown in fig. 5.

In the system according to the invention, a vehicle aisle can be laid under the elevated track, thus realizing a three-dimensional track freight system.

According to another aspect of the invention, a ground track system can be laid under the overhead track, and the overhead track can also automatically run along the track in the ground track system, and the overhead track and the truck on the ground track are automatically controlled by the control device, thereby realizing an automatic three-dimensional track freight system.

As shown in fig. 1 and 2, a maintenance zone 15 is provided at the most distal end of the system. The service area 15 also has first and second overhead service area rails 151, 152 and is provided with access facilities such as ramps and operating platforms for access by service personnel.

As shown in fig. 2, the translational derailment region 12 is disposed adjacent to the maintenance region 15 and the aerial rail operation region 11, respectively, such that the translational derailment region 12 is disposed between the maintenance region 15 and the aerial rail operation region 11. In this way, at least one of the first and second overhead movable rails 121, 122 of the translating derailment zone 12 can interface with either of the two parallel overhead service zone rails 151, 152 of the service zone 15, and at the same time, lateral translation of the first and second overhead movable rails 121, 122 in the translating derailment zone 12 also enables transfer of the truck 200 between the different rails 151, 152 of the service zone.

In addition, the maintenance area 15 may also be provided with more overhead maintenance area tracks in parallel, for example, three, and any of the two overhead movable tracks in the translational track transfer area 12 can be laterally translational abutted to any of the three maintenance area tracks, so as to accommodate more vehicles for flexible scheduling.

The rails 151, 152 in the maintenance zone 15 may be constructed using one or more rail steel modules 100 of the same shape and configuration as the transport zone 2.

The arrangement of the maintenance area 15 in the system does not occupy the round-trip operation area of the carrier 200, the carrier does not need to be transferred to the ground, the maintenance can be directly carried out on the overhead track, and meanwhile, the interactive operation of the transported object 600 is not influenced.

The truck 200 used in the system is electrically driven, for which purpose the power supply lines for supplying power to the truck are laid along the overhead track. For a system of a pair of overhead rails arranged in parallel, the power supply line may be laid in the middle of two overhead rails, or may be laid along the top rail beam in one overhead rail. And an overhead power supply facility is not needed, and the construction is convenient.

Furthermore, the system according to the invention may be suitable for transportation across two-place cargo distribution centers at the border. To enable cross-border transportation, the transportation zone in the overhead rail transportation system according to the present invention may further comprise one or more of the following cross-border functional zones: a power conversion area, a spraying and killing area, a nuclear radiation inspection area, an information comparison area and the like.

The carrier advances along the track of transportation district, because the use standard of electric wire netting between the different countries is different, can realize power standard conversion through trading the electric district to match the electric wire netting standard of current country or region that locates. In addition, according to the requirements of cross-border transportation, the carrier moves along the track of the transportation area to pass through the functional areas such as the spraying disinfection area, the nuclear radiation inspection area and/or the information comparison area, so that operations such as cargo disinfection, nuclear radiation inspection and information inspection are realized. The whole process can be automatically operated under the remote control of the control equipment of the system, so that the requirement of high-efficiency cross-border transportation is met.
