Description

Technical Field

[0001] The present invention relates to the technical field of loading and unloading cargo in carriages, and in particular to a counter-point logistics platform system for automatic and rapid loading and unloading of cargo. Background Art

[0002] The current technology of cargo loading and unloading systems for high-speed rail logistics platforms using AGV forklifts is that the AGV forklifts can only calibrate the position of the pallet in the carriage after the carriage door is opened when the train docks. It cannot accurately calibrate in advance before the carriage door opens, resulting in longer transportation time. In addition, the time it takes for the fork arm of the AGV forklift to extend and retract to the pallet cargo in the carriage is relatively long, and the cargo in the carriage needs to be loaded and unloaded one by one by the AGV forklift. It cannot unload or load multiple cargo locations simultaneously, and the overall loading and unloading process takes a long time, making it impossible to achieve rapid alignment and synchronous loading and unloading of cargo.

DETAILED DESCRIPTION

[0032] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings of the specification to make the technical solutions and beneficial effects of the present invention clearer and more specific.

[0033] According to an interview with Qilu Evening News, Xie Yinsuo, a senior engineer of the Transportation Department of China Railway Jinan Bureau Group Co., Ltd., said that the high-speed train takes about 7 minutes to stop at a station, including 3 minutes to slow down to a stop, 2 minutes to stop at the station, and 2 minutes to start. According to the actual data, the actual loading and unloading time at the station is only 2 minutes, that is, the average loading and unloading time is only 60 seconds each.

[0034] See also Figure 1-10The embodiment shown is an automated fast loading and unloading counter-point logistics platform system, which includes: a cargo compartment 1 moving along a high-speed rail track, on which is provided a compartment cargo track 2, a compartment transfer device 3 movable and arranged on the compartment cargo track 2 for transferring cargo, and a compartment sensor 10 for sending compartment stop position information; the compartment transfer device 3 includes: a transfer and conveying assembly 31 installed on the cargo compartment 1 and a roller conveying assembly 32 installed above the transfer and conveying assembly 31 for conveying cargo; a docking platform 4 arranged on both sides of the high-speed rail track stop station, on which is provided a platform cargo track 41 docking with the compartment cargo track 2, a cargo trolley moving along the platform cargo track 41 and docking with the compartment transfer device 3 for conveying cargo, a platform sensor 40 for receiving compartment stop position information, and a platform logistics controller (not shown) for controlling the cargo trolley to convey cargo, the platform logistics controller connecting the compartment sensor 10 and the platform sensor 40. Therefore, it takes 3 minutes for the high-speed train to slow down and stop at the station. When the vehicle enters the station, the "high-speed sensors" installed in the carriages and platforms transmit the vehicle entry information and the estimated parking position of the carriage doors (generally, the front and rear difference between the carriage doors and the center of the platform is ±500 mm). Even if the high-speed train carriages have begun to slow down before entering the station, they still have a certain walking speed (10 to 30 km / h) before entering the station and stopping completely. The performance requirements for sensors to capture high-speed movement are relatively high (generally, sensors capture feedback signals of stationary or low-speed moving objects). Therefore, the corresponding sensors installed in the carriages and platforms must have the ability to capture feedback signals for high-speed moving objects. (The speed of moving objects is 10 to 30 km / h)

[0035] Therefore, the carriage sensor 10 and platform sensor 40 in this embodiment must have the ability to capture signal feedback of moving objects (moving speed 10~30KM / H). Because the train is transported outdoors, the vehicle will inevitably be affected by the surrounding environment when entering the station, so the sensor must also have the performance of resisting the influence of factors such as rain, dense fog, and strong light.

[0036] like Figure 1-2 As shown, in this embodiment, a roller cargo assembly 50 is provided on the cargo trolley 5, and the roller cargo assembly 50 has the same structure as the roller conveying assembly 32 and the two are on the same horizontal plane. A cargo trolley sensor 51 is provided on the cargo trolley 5, and the cargo trolley sensor 51 is connected to the platform logistics controller, and performs signal exchange with the carriage sensor 10 and the platform sensor 40, so as to realize the capture of cargo transportation information of the vehicle entering the station.

[0037] In this embodiment, the freight trolley is set as an RGV mobile trolley, and the parameter requirements of the RGV mobile trolley can be set: walking accuracy: RGV trolley moving and parking accuracy ±3 mm; moving and proofreading speed: after the carriage stops, the precise movement and proofreading actions must be completed within 5 seconds; load requirement: 2 to 3 tons / car; transmission mechanism: chain transmission; walking mechanism: rack and gear (special treatment is required, the load-bearing requirement is 4 to 500KG / gear).

[0038] When the sensor captures the information of the vehicle entering the station, it is fed back to the platform logistics controller for command coordination. The platform logistics controller issues a command to the RGV trolley, and the trolley moves to the expected stop position of the carriage door in advance. The final stop position of the carriage will have a certain deviation from the size of the center of the platform unloading port (deviation range ±500 mm), and the final specific stop position of the carriage will have deviations for each train. After the vehicle stops (before the door opens), the actual stop position of the train carriage is fed back to the platform logistics controller to the RGV trolley through the sensor. The RGV trolley moves accurately to the center of the carriage door and docks with the conveyor line in the carriage. The essential requirement for the trolley to travel and stop is ±3 mm. Because the size of the carriage is relatively compact, in order to save space and improve utilization, the distance between the positions of each pallet is relatively close. Therefore, the RGV trolley is generally set to carry 2 to 3 pallets / car. The trolley load needs to reach 2 to 3 tons / car. In order to prevent slipping after walking in place, chain drive is adopted, and the running wheels are in the form of gears and racks.

[0039] In this embodiment, the platform sensor 40 is installed on the side wall of the docking platform 4 facing the high-speed rail track, the platform cargo track 41 is arranged longitudinally along the platform and close to the high-speed rail track, a hoist 6 is vertically arranged on one side of the platform cargo track 41, and a hoist track 61 docking with the platform cargo track 41 is arranged on the hoist 6, and the freight trolley moves longitudinally along the platform cargo track 41 and can move transversely between the high-speed rail track and the hoist track 61, and is used to carry the goods on the carriage to the hoist track 61. The hoist 6 is provided with a lifting and conveying assembly having the same structure as the roller conveying assembly 32, and the lifting and conveying assembly 60 is movably arranged on the hoist track 61.

[0040] like Figure 8-9As shown, in this embodiment, the transfer and conveying assembly 31 includes: a transfer bracket 311 fixed on the carriage, and transverse guide rails 3110 are provided on both sides of the transfer bracket 311. A support seat 312 for supporting the roller conveying assembly 32 is provided on the inner side of the transfer bracket 311. A transfer motor 313 is installed on the support seat 312. A main sprocket 314 passing through the support seat 312 is provided at one end of the transfer motor 313. A slave sprocket 316 connected to the main sprocket 314 through a transmission chain 315 is provided on one side of the support seat 312. The main sprocket 314 is on the same straight line, and the two ends of the transmission chain 315 are respectively connected to the limit bolts 317, which are fixed on the transfer bracket 311. The two ends of the support seat 312 are provided with passive rollers 318 vertically mounted on both sides of the transfer bracket 311. The two ends of the passive roller 318 are abutted on the cross bars on both sides of the transfer bracket 311, so that the support seat 312 can be driven by the transfer motor 313 along the transverse guide rail 3110 of the transfer bracket 311 to move laterally to approach or away from the platform cargo track 41.

[0041] In this embodiment, limit blocks 319 are provided at both ends of the passive roller 318, and the limit blocks are arranged between the side of the support seat 312 and the vertical rod of the transfer bracket 311. The limit blocks 319 can abut against the vertical rod of the transfer bracket 311 under the drive of the passive roller 318, so as to limit the lateral movement distance of the passive roller 318.

[0042] In this embodiment, a limiting pulley 310 located on the inner side of the transfer bracket 311 is arranged below the passive roller 318. The limiting pulley 310 is horizontally rotatably arranged below the limiting block 319 so that it can abut against the inner side of the cross bar of the transfer bracket 311 when the passive roller 318 drives the support seat 312 to move horizontally, so as to limit the vertical shaking of the support seat 312 and ensure the precise alignment of the roller conveying assembly 32 and the freight cart.

[0043] like Figure 8 , 10 As shown in the present embodiment, the roller conveying assembly 32 includes: a roller bracket 321 fixed above the transfer conveying assembly 31 and a roller motor 322 installed below the roller bracket 321, multiple roller mounting holes 324 for mounting rollers 323 are opened on both sides of the roller bracket 321, and the multiple roller mounting holes 324 are evenly arranged horizontally. One end of the roller 323 passes through the roller mounting hole 324 and is fixed on the roller bracket 321, and the other end of the roller 323 is provided with a roller wheel 325 passing through the roller mounting hole 324. The multiple rollers 323 are connected to the roller motor 322 through their respective roller wheels 325 via the same roller chain 326 for rotation.

[0044] In this embodiment, the installation height of the carriage transfer device 3 does not exceed 400 mm.

[0045] A method for conveying goods in a counter-point logistics platform system for automatic and rapid loading and unloading, comprising the following steps:

[0046] S1, before the carriage stops after entering the station, the carriage sensor 10 feeds back the carriage stop position signal about the carriage entry information and the estimated parking position information of the carriage door to the platform logistics controller on the platform. After receiving the signal, the platform logistics controller feeds back the carriage stop position signal to the freight trolley in advance, and the freight trolley moves forward or backward on the platform freight track 41 in advance to the vicinity of the carriage door stop position for preliminary alignment movement;

[0047] S2, after the carriage stops steadily and before the carriage door opens, the carriage sensor 10 feeds back accurate parking position information to the cargo trolley, and the cargo trolley receives the signal and performs position fine-tuning correction, so that the cargo trolley and the carriage transfer device 3 on the carriage are aligned, and wait for the door to open;

[0048] S3. After the carriage stops steadily and before the carriage door opens, the carriage sensor 10 feeds back the precise parking position information of the carriage to the platform logistics controller and at the same time feeds back a signal to the carriage transfer and conveying device in the carriage. After the carriage door opens, the carriage transfer and conveying device controls the roller conveying assembly 32 to move horizontally to the platform track, shortening the distance between the carriage transfer and conveying device and the platform, and docking the goods on the roller conveying assembly to the freight cart.

[0049] Specific: such as Figure 3-7 As shown, the conveyor line equipment is installed in the train freight car, and there are door opening and unloading positions on both sides of the car. Since the train stops for only 2 minutes or less, a series of actions need to be completed within this time period for loading and unloading goods: the car door opens → the conveyor line moves closer to the platform → the goods are transported to the RGV trolley on the platform → the conveyor line moves in the opposite direction to the cargo platform to receive the goods → the goods are delivered to the conveyor line → the conveyor line is moved to the regular position of the train → the car door is closed. As a result, the present invention shortens the time for loading and unloading goods from the car to the platform, improves the efficiency of loading and unloading, and reduces the operation time required for the high-speed rail / train to stop for loading and unloading goods.

[0050] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
