Description

Direct taking, loading and unloading operation system and method for molten iron combined transport vehicle and ship at front edge of container terminal
Technical Field
The invention relates to the technical field of cargo transportation, in particular to a direct taking, loading and unloading operation system and method for a molten iron combined transport vehicle and ship at the front edge of a container terminal.
Background
The combined transportation of the containers and the molten iron refers to the transportation process that the containers are reloaded to ships through trains or reloaded to the trains through the ships, so that the space displacement and the time displacement of goods are realized, the whole process only needs 'reporting once, checking once and releasing once', the combined transportation method is an advanced comprehensive transportation mode in the world at present, and has the comprehensive advantages of realizing seamless connection of goods transportation, saving logistics cost, reducing energy consumption, reducing pollutant emission and the like.
At present, the hot metal combined transportation modes of the container mainly comprise the following modes:
1. the first mode is as follows: the railway loading and unloading line is positioned in a storage yard behind the port. In the mode, a certain distance exists between a railway container loading and unloading line and a wharf shore bridge, and a certain number of internal collection trucks are required to be equipped for container reloading transportation to carry out short barge through in-site road transportation.
2. And a second mode: the railway loading and unloading line extends to the front edge of a wharf, the reloading operation between the waterway transportation and the railway transportation does not pass through the yard operation, and the containers can be directly taken by vehicles and ships through a shore bridge. Therefore, the containers can be directly reloaded without being stocked in a storage yard, the transportation links of collection trucks, the stockpiling operation links in the storage yard and the number of loading and unloading machines are reduced, the area of the storage yard is greatly saved, the operation time is shortened, and the social and economic benefits are higher.
The limitation analysis of the existing mode of the container molten iron combined transportation is as follows:
the operation flow of the mode one is as follows:
vessel ← → shore container crane (shore bridge) ← → inside dump truck ← → rear yard and yard gantry crane ← → railway loading and unloading line gantry crane ← → railway vehicle.
The operation flow of the second mode is as follows:
vessel ← → shore container crane ← → quay front railway loading and unloading line vehicle.
The problem with mode one is:
1) the internal container truck transportation link and the loading and unloading transportation equipment are added, and the transportation cost and the time cost are correspondingly increased.
2) The railway loading and unloading area needs to be provided with loading and unloading equipment and a storage yard, so that the engineering investment is large and the operation cost is increased.
The problem with mode two is:
1) the railway vehicle is unpowered to stay on a loading and unloading line at the front edge of the wharf, and the ship is fixedly anchored in a berth state during loading and unloading at the port; the container between the ship and the railway vehicle needs to be loaded and unloaded by the longitudinal movement of the quay crane at the front of the wharf. As the longitudinal moving speed of the shore bridge (the big vehicle) is lower by 45m/min, the reciprocating moving distance of each hook is 100-600 m (the average moving distance is 350m), and only 6-10 standard containers can be loaded and unloaded in each hour in the moving process. The shore bridge needs to move back and forth between the vehicle and the ship along the track for operation, the efficiency is low, and the adjacent shore bridge blocks the walking of the operation shore bridge. The main time is wasted in the running of the shore bridge equipment. And the front edge of the wharf can not realize the synchronous operation of a plurality of shore bridges. Therefore, a railway loading and unloading line is not arranged below the front shore bridge of the wharf, and the railway loading and unloading line is basically stopped.
2) The operation method of the railway loading and unloading line under the shore bridge is that the shore bridge does not move during the loading and unloading of the container, and the railway loading and unloading vehicle moves longitudinally under the traction of the tractor to align with the shore bridge and is matched with the loading and unloading operation of the shore bridge. The available length of the railway loading and unloading line laid at the front edge of the wharf by the operation method is only half of the total length of the loading and unloading line, namely the loading and unloading line of 400m can only be used for loading and unloading operation of vehicles of 200m length, loading and unloading blind areas are arranged at two ends of the front edge of the wharf, and each track needs to be provided with a special traction locomotive. And a rack is laid in the middle of a port railway loading and unloading line track. The rack-and-pinion vehicle is driven by a motor, is supplied with power through a cable drum, and is transmitted to a driving gearwheel through a gear reduction box and a chain in a speed reduction manner, and the driving gearwheel is meshed with a rack fixed in the middle of a track, so that the marshalling vehicle moves forward. The train stops at a designated position after going to a wharf, the train is loaded and unloaded by the existing equipment of the wharf after the train head is picked up and hooked, and after each group of containers is operated, the rack rail vehicle pushes the train to advance to a container operation position, so that the movement of the container loading and unloading equipment cart is greatly reduced, and the loading and unloading efficiency is improved. After the whole train is operated, the train is pulled by the train head to leave the wharf. One loading and unloading line can only be matched with one shore bridge for loading and unloading operation, although the efficiency of directly taking the railway vehicle and ship by the shore bridge can reach 45-60 boxes/hour, the efficiency of directly taking the loading and unloading operation by the shore bridge is greatly increased compared with that of directly taking the railway vehicle and ship by the shore bridge, the capacity utilization rate of the wharf railway loading and unloading line is only 50%, the shore bridge in synchronous operation is limited, and the capacity utilization of a water public transport channel is limited to a certain extent.
3) The loading and unloading mode at the front of the wharf must keep information intercommunication between the ship and the railway train, and the arrival and departure time of the railway train, the arrival and development time of the wharf ship, the loading and unloading operation plan of the loading and unloading mechanical vehicle and the like are well coordinated, otherwise, a great amount of waiting idle time is increased for the railway train and the ship.
The following conclusions were obtained from the above analysis:
the railway loading and unloading line in the first mode has more links in the horizontal transportation of the container molten iron in the rear yard mode, has higher transportation and time cost, is suitable for container terminals with large transportation capacity, and can reduce the cost by spreading the transportation capacity.
And the railway loading and unloading line of the second mode extends to the wharf front edge vehicle and ship direct taking mode, the control information intercommunication between the ship and the train is required, the operation process is matched, the loading and unloading efficiency of the moving operation of the shore bridge is lower, the operation of other shore bridges is influenced, and the tractor mode has dead angle dead zone of operation.
Along with the development of information technology, the mutual communication of the molten iron combined transport information can be realized, and a shore bridge moving loading and unloading mode which influences the operation efficiency of a container vehicle and ship direct taking mode at the front edge of a wharf is adopted. Changing the direct-taking operation system and the operation process (method) of the vehicle and the ship is a way to improve the efficiency of the combined transportation of molten iron, so that a new direct-taking loading and unloading operation system and a new direct-taking loading and unloading operation method of the combined transportation of molten iron at the front edge of the wharf are urgently needed to solve the technical problems.

The following are several embodiments of the three-dimensional continuous loading and unloading method for the container vehicle and ship according to the present invention.
Example one
Referring to fig. 1 and fig. 3, the present embodiment takes 1 strand of railway loading and unloading line as an example, and explains a direct taking operation flow of a ship, an unloading railway, a loading railway and a loading railway, and the steps are as follows:
(1) the quay crane 300 unloads the multi-type intermodal yard water and public intermodal containers onto the collection truck 400 of the lane 200 according to the operation plan, and the collection truck exits from the front edge of the wharf along the road; after the molten iron intermodal container is grabbed and lifted from the ship and transported to the shore bridge, the cantilever 302 is unloaded to the cross-over box position of the cross-over yard 500.
(2) When the arrival times of the ship and the train can be matched, the gantry crane 600 moves to the transfer box location, lifts the container, and directly transfers the container to the railway vehicle 710 through longitudinal traveling and transverse displacement. This is repeated until the rail vehicle is full and the rail locomotive pulls the train 710 out of the rail loading line 700.
The working areas of the plurality of gantry cranes 600 running on the same track 604 need to be divided to prevent work conflicts. The gantry cranes 600 can be operated separately or synchronously, and the operation areas are partially overlapped to realize container transfer. If the left area of the shore bridge rear cantilever 302a is loaded by the gantry crane 600a, the right area is loaded by the gantry crane 600b, and the two gantry cranes have overlapped operation areas in the shore bridge rear cantilever 302 area.
Because the railway train is a long and large train group (the length of a train can reach kilometers), when the running range of the containers for unloading and loading exceeds the range of the set operation area of one portal crane, a plurality of portal cranes can carry the containers in a relay manner. For example, the container unloaded from the quayside crane rear boom 302a at the transfer yard 500 is transferred to the right-side rail vehicle 710 along the rail loading line 700 by the force of the gantry crane 600b, the container 100 is dropped at the transfer yard 500 transfer point in the overlapping area of the operations of the gantry cranes 600b and 600c, and the gantry crane 600c lifts the container 100 at the transfer point and continues to transfer the container to the predetermined rail vehicle 710 position right along the rail loading line.
(3) When the empty wagon vehicle 710 does not reach the loading and unloading line in the waiting process of the empty wagon traction and empty wagon propulsion empty wagon exchange, or the arrival time of the railway vehicle 710 is not matched with the short-time capacity of the container ship 10, and the unloading can not be stopped, the shore bridge 300 continues unloading, the shore bridge 300 unloads the containers from the ship 10 to the cross-over yard 500, the portal crane 600 lifts the containers 100 of the cross-over yard 500 under the cantilever of the shore bridge, the containers to be loaded are transferred to planned boxes of longitudinal boxes (500a, 500b and 500c) of the cross-over yard 500 according to longitudinal partitions for temporary storage, and the containers temporarily stored in the cross-over yard 500 are sequentially lifted from the temporary boxes to be transferred to the railway vehicle 710 after the railway vehicle 710 arrives.
(4) After the loading of the whole train container is finished, the traction locomotive pulls the train to the adjacent station marshalling and then sends out or directly sends out on a loading and unloading line.
(5) The highway collection truck and the railway train can complete the delivery of goods tickets and real objects without stopping the train through electronic information acquisition at a port inspection gateway.
(6) The container ships 10a, 10b can simultaneously carry out loading and unloading operations at the berths 21a, 21b at the wharf front, and the shore bridges 300a, 300b can simultaneously carry out loading and unloading operations on different ships respectively, or can simultaneously carry out loading and unloading operations on one of the ships. The gantry cranes 600a, 600b, 600c, 600d flexibly divide the working area as required, and can all load containers for one shore bridge or respectively load containers for a plurality of shore bridges. The ship 10, the shore bridge 300, and the gantry crane 600 can flexibly arrange and combine the rail vehicle 710 for unloading the ship according to the operation plan.

the contents of ship, railway information planning and scheduling in the front and ship, shore bridge and gantry crane combination arrangement and matching in the back of the embodiment are the same as those in the first embodiment, and are not described again.
(1) The empty train of the railway container is to send the railway vehicle 711 to the railway loading and unloading line 701 spanned by the gantry crane 600 through the railway locomotive at the station according to the instruction given by the railway container transportation management system.
(2) The quay crane 300 unloads the multi-type intermodal yard water and public intermodal containers onto the collection truck 400 of the lane 200 according to the operation plan, and the collection truck exits from the front edge of the wharf along the road;
the shore bridge 300 picks up and lifts the molten iron intermodal container from the ship to the shore bridge, and then the cantilever 302 is unloaded to the transfer box position of the transfer yard 500.
(3) The gantry crane 600 moves to the cross-over area 500, lifts the container, and transfers it directly to the railway vehicle 711 on the railway loading/unloading line 701 by traveling in the longitudinal direction and by lateral displacement. This is repeated until the rail vehicle is full and the rail locomotive traction vehicle train 711 exits the rail loading/unloading line 701.
(4) During loading of the railway vehicle 711 on the railway loading line 701, the railway locomotive sends a train of empty railway vehicles 712 to the railway loading line 702. The gantry crane 600 moves to the cross-over area 500, lifts the container and transfers it directly to the rail vehicle 712 on the rail loading line 702 by traveling in the longitudinal direction and by lateral displacement. This is repeated until the rail vehicle is full and the train 712 of rail locomotives pulled out of the rail loading and unloading line 702 again.

Because the train is a long and large train set (the length of a train can reach kilometers), when the running range of the unloaded and loaded container exceeds the range of the set operation area of one portal crane, a plurality of portal cranes can carry the container in a relay manner. For example, the gantry crane 600c lifts a container in the rail vehicle 710 on the right side of the middle of the railway loading and unloading line 700 and transfers the container to the rear cantilever 302a of the left side shore bridge, and places the container 100 at the transfer location in the transfer yard 500B area where the operations of the gantry cranes 600B and 600c overlap, the gantry crane 600B lifts the container 100 at the transfer point and continues to transfer the container to the left of the railway loading and unloading line 700 and to the predetermined transfer yard 500 transfer location under the rear cantilever 302a of the shore bridge, and the shore bridge trolley moves laterally to the container ship 10 at the transfer location and unloads the container, and the unloading and loading are completed.
