Description

Technical Field

[0001] The utility model relates to the technical field of transportation, in particular to an underground container logistics conveying module. Background Art

[0002] Since many container ports are scattered and most of them lack railway branches directly into the port areas, port container transportation mainly relies on road collection and distribution transportation, that is, the containers at the port need to be transported to the freight station by trucks first and then transported by trains, which not only increases the difficulty of container transportation coordination, but also affects the efficiency of transportation. At the same time, since road transportation is easily affected by road conditions, it affects the efficiency of container transshipment.

[0003] The theory of underground container transportation system originates from the research and application of underground logistics system. Since the 1990s, the development and utilization of underground space and the research of underground logistics system have been highly valued in some Western countries, and it is regarded as the fifth type of transportation and supply system in addition to traditional road, rail, air and water transportation. In the underground container transportation system, the automatic guided vehicle is generally used as the carrier, and the container is the basic transportation unit. The automatic navigation system is highly automated and accurate, and the automatic guided vehicle automatically shuttles the container in the large-diameter underground passage.

[0004] In underground container transportation systems, containers are generally heavy and need to be moved to the AGV by crane. During the loading and unloading process, the sling on the crane needs to be moved according to the position of the AGV to ensure that the container can be accurately placed on the AGV or stably moved from the AGV, which makes the operation requirements of the crane relatively high and will affect the transfer efficiency to a certain extent. At the same time, since containers come in a variety of sizes, a single-size AGV cannot be fully applicable to large-size containers, and there is a problem of insufficient support and transportation strength. Although multiple AGVs can be used together to transport large-size containers, it will greatly increase the difficulty of transportation coordination between AGVs. Utility Model Content

[0005] The utility model aims to provide an underground container logistics conveying module, which improves the efficiency of transshipment, ensures the stable conveyance of containers, and improves the flexibility of use and the scope of application.

[0006] The technical solution adopted by the utility model to solve the above problems is:

[0007] An underground container logistics transportation module, comprising:

[0008] The car body is used for the transfer of containers between ports and freight stations. The car body moves along the track underground through the drive assembly;

[0009] A positioning assembly used for positioning between the car body and the spreader of the container crane;

[0010] A limit assembly, which is used to limit the movement of the container on the vehicle body;

[0011] Wherein, matching connecting heads and connecting grooves are respectively provided at the two ends of the vehicle body in the moving direction, and a locking assembly for preventing the connecting head from being separated therefrom is provided in the connecting groove.

[0012] As a further improvement of the above technical solution, the locking assembly includes two clamping seats, which are symmetrically arranged relative to the connecting groove. The clamping seats are slidably arranged on the vehicle body and slide relative to the vehicle body through a first linear drive device. An annular groove is opened on the connecting head along its circumference to form a recessed portion. First grooves are opened on the opposite sides of the two clamping seats. When the two clamping seats are pressed against each other, the two first grooves are combined to form a clamping groove for accommodating the recessed portion.

[0013] As a further improvement of the above technical solution, the mobile component includes a plurality of drive units, each drive unit is arranged in a straight line and at equal intervals on the vehicle body, the drive unit includes two drive wheels with a brake structure, the drive wheels are rotatably arranged on the vehicle body and are rotated relative to the vehicle body by a motor, and a second groove is provided on the drive wheel for accommodating the underground track.

[0014] As a further improvement of the above technical solution, the positioning component includes four infrared receivers, which are arranged in four directions on the four corners of the top surface of the vehicle body, and the lifting device is provided with an infrared transmitter compatible with the infrared receivers.

[0015] As a further improvement of the above technical solution, the limiting assembly includes a plurality of magnetic units, each of which is symmetrically arranged on the vehicle body. The magnetic unit includes an electromagnet, which is embedded in the top surface of the vehicle body. The vehicle body fixes the container thereon through the electromagnet.

[0016] As a further improvement of the above technical solution, the connecting head is horizontally slidably arranged on the vehicle body and slides relative to the vehicle body through a second linear drive device.

DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0031] See also Figure 1-Figure 8 The present embodiment provides an underground container logistics transportation module, including a car body 1, a positioning component 2 and a limiting component 3. The car body 1 is used for the transfer of containers between ports and freight stations. The car body 1 is moved along the underground track by a driving component 11. Matching connectors 41 and connecting grooves 42 are respectively provided at both ends of the moving direction of the car body 1. A locking component 5 for preventing the connector 41 from detaching therefrom is provided in the connecting groove 42. The positioning component 2 is used for positioning between the car body 1 and the spreader of the container crane. The limiting component 3 is used for limiting the movement of the container on the car body 1.

[0032] When the container is transshipped, the container located at the port is picked up by the spreader of the container crane and moved to the top of the car body 1 on the underground track between the port and the freight station. The positioning component 2 is then used to position the spreader and the car body 1 so that the spreader can lower the container vertically directly onto the car body 1, and fix the container on the car body 1 by the limit component 3. The car body 1 is then moved along the underground track by the drive component 11 to transport the container from the port to the freight station, and the container is removed from the car body 1 by the container crane at the freight station, thereby completing the transshipment of the container between the port and the freight station.

[0033] Among them, the freight station, as a container transshipment station, can have both railway transportation lines and road transportation lines to connect different modes of transportation, so that the containers located at the freight station can be transported over long distances by container freight trains or transported over short distances by container trucks, thereby improving the efficiency of road-rail combined transportation in port container transportation.

[0034] In this embodiment, the vehicle body 1 is provided with a GPS locator or a Beidou locator, which achieves the effect of locating the position of the vehicle body 1 in the underground passage, so that when a sudden failure occurs during the process of the vehicle body 1 transporting the container, the position of the vehicle body 1 can be determined in time and accurately for maintenance, thereby reducing the impact of the failure of the vehicle body 1 on the transportation efficiency.

[0035] See also Figure 2 , Figure 3 The locking assembly 5 includes two clamping seats 51, which are symmetrically arranged relative to the connecting groove 42. The clamping seats 51 are slidably arranged on the vehicle body 1 and slide relative to the vehicle body 1 through a first linear drive device 52. The moving directions of the two clamping seats 51 are opposite. An annular groove 43 is opened on the connecting head 41 along its circumference to form a recessed portion 44. First grooves 53 are opened on the opposite sides of the two clamping seats 51. When the two clamping seats 51 are against each other, the two first grooves 53 are combined to form a clamping groove 54 for accommodating the recessed portion 44.

[0036] When the connecting head 41 is inserted into the connecting groove 42, the driving effect of the first linear drive device 52 on the clamping seat 51 causes the two clamping seats 51 to move synchronously in opposite directions until the two clamping seats 51 are against each other. At this time, the first grooves 53 on the two clamping seats 51 are spliced ​​to form a clamping groove 54 and the recessed portion 44 is located in the clamping groove 54, so that the connecting head 41 cannot be separated from the connecting groove 42 under the restriction of the two clamping seats 51, thereby realizing the connection between two adjacent car bodies 1, and ensuring that when the length of the container exceeds the length of the car body 1, multiple car bodies 1 can be used in combination in sequence to support and transport the container.

[0037] In this embodiment, the connecting head 41 is horizontally slidably arranged on the vehicle body 1 and slides relative to the vehicle body 1 through a second linear drive device 45, so that the connecting head 41 can be stored in the vehicle body 1, which can reduce the impact on the visual aesthetics of the vehicle body 1 while also playing a certain protective role, reducing the risk of the connecting head 41 being damaged by bumps.

[0038] See also Figure 4 , Figure 5 The mobile assembly includes a plurality of drive units 12, each of which is arranged on the vehicle body 1 in a straight line with equal spacing. The drive unit 12 includes two drive wheels 13 with a brake structure. The drive wheel 13 is rotatably arranged on the vehicle body 1 and rotates relative to the vehicle body 1 through a motor 14. The drive wheel 13 is provided with a second groove 15 for accommodating the underground track, which reduces the risk of the drive wheel 13 detaching from the underground track. By setting a plurality of drive units 12 on the vehicle body 1, the support effect of the vehicle body 1 when loaded is improved, and the mobile transportation effect of the vehicle body 1 is also guaranteed, thereby ensuring the transportation efficiency of the container.

[0039] See also Figure 6 , Figure 7 The positioning assembly 2 includes four infrared receivers 21, which are arranged in four directions on the four corners of the top surface of the vehicle body 1, and an infrared transmitter 22 adapted to the infrared receivers 21 is provided on the sling.

[0040] When the spreader moves to the top of the moving track of the vehicle body 1, the vehicle body 1 moves so that the four infrared receivers 21 all receive the infrared rays emitted by the infrared transmitter 22 on the spreader. At this time, the spreader is located above the vehicle body 1, and the spreader moves vertically to place the container on it on the vehicle body 1 or remove the container on the vehicle body 1, which greatly reduces the difficulty of accurately controlling the movement of the spreader during container loading and unloading, improves the convenience of the container crane in loading and unloading containers on the vehicle body 1, and also ensures the efficiency of transportation.

[0041] See also Figure 8 The limiting assembly 3 includes a plurality of magnetic units 31, each of which is symmetrically arranged on the vehicle body 1. The magnetic unit 31 includes an electromagnet 32, which is embedded on the top surface of the vehicle body 1. The vehicle body 1 fixes the container thereon through the electromagnet 32.

[0042] When the container is placed on the vehicle body 1, the container is fixed on the vehicle body 1 under the action of the electromagnet 32, thereby ensuring the stability of the container on the vehicle body 1 and the transportation effect during the process of the vehicle body 1 transporting the container, and when the container needs to be removed from the vehicle body 1, the electromagnet 32 ​​releases the suction effect on the container, so that the container and the vehicle body 1 are released from the fixed state.

[0043] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
