Description

Technical Field

[0001] The present application relates to the field of automated terminals, and in particular to an IGV operation method for a liner berth at an automated terminal. Background Art

[0002] In the horizontally arranged automated container terminal, the lock pin channel is adjacent to the shore lane and arranged perpendicular to the shore. Since there are booths for workers to disassemble and install the lock pins between the lock pin channels, the IGV (intelligent guided vehicle) needs to enter the lock pin channel vertically. For example, in the conventional 6-lane quay crane lane, the 6th and 5th quay crane lanes closest to the lock pin channel are too close to the lock pin channel, and the turning radius of the IGV is not enough to support a direct vertical turn into the lock pin channel, so it is necessary to turn into the 4th lane first and then turn from the 4th lane to enter the lock pin channel. Because the IGV cannot use the working lane to pass, when the 5th lane is used as the working lane, the 6th lane cannot be used as the working lane or the passing lane, and is actually idle. This is a great waste for the precious front area of ​​the terminal. At the same time, since the IGV in the 3rd working lane and the IGV in the 5th working lane need to use the 4th lane to go down, the 4th lane is abnormally crowded, which may cause blockage and affect the overall berth traffic efficiency. Summary of the invention

[0003] The present invention aims to overcome at least one defect of the above-mentioned prior art and provide an IGV operation method for an automated terminal liner berth to solve the problem of idle and unusable quay crane lanes.

[0004] The present invention provides an IGV operation method for an automated terminal liner berth, the method comprising:

[0005] The quay crane lane is divided into an operation lane and a traffic lane. The operation lane is a lane occupied by the quay crane operation position, and the traffic lane is a lane occupied by the IGV leaving after the operation is completed or going to the quay crane operation position;

[0006] A locking pin channel is provided, and the locking pin channel is used for locking pin operation and downshifting;

[0007] The IGV that needs to remove the lock pin turns from the traffic lane and passes vertically through the lock pin channel to shift down;

[0008] The IGV, which does not need to disassemble or assemble the locking pin, turns from the traffic lane and passes through the neutral area to shift down. The neutral area is arranged between the locking pin channel and the quay crane.

[0009] Furthermore, the passing lane and the working lane are spaced apart from each other, and the passing lane that passes through the neutral area to downshift after the passing lane turns is the passing lane with the shortest vertical distance to the locking pin channel.

[0010] Furthermore, the locking pin channel is greater than 29 meters away from the quay crane.

[0011] Furthermore, the state of the lock pin channel includes an open state and a closed state. The lock pin channel in the open state can be applied for passage by the IGV, and the lock pin channel in the closed state is not allowed to be applied for passage by the IGV.

[0012] Furthermore, the locking pin channel is bound to the liner, and only the IGV belonging to the liner mission is allowed to pass through the bound locking pin channel.

[0013] Furthermore, the lock pin channel includes a passage and a safety island, and the passage includes an IGV guide mark, a reflective column and a lock pin frame.

[0014] Furthermore, the IGV guide marks are distributed at both ends of the passage, and the IGV guide marks are diamond-shaped guide marks.

[0015] Furthermore, the safety island is a movable sentry box placed on both sides of the passage.

[0016] Furthermore, the neutral area is provided with a first lower gear channel, and the first lower gear channel is arc-shaped.

[0017] Furthermore, the neutral area is provided with a second down-gear passage, and the second down-gear passage is in a reverse zigzag shape.

[0019] First, the outer lane of the quayside bridge can be used as a traffic lane, which makes reasonable and effective use of shore resources;

[0020] Second, it can reduce the chance of IGVs queuing in the lanes to downshift due to insufficient passageways, thus reducing congestion.

[0021] Third, the number of lock pin channels opened can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The drawings of the present invention are only for illustrative purposes and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0028] The present application embodiment provides an automated terminal liner berth IGV3 operation method for solving the problem of insufficient utilization of quay crane lanes. Figure 1 , an IGV3 operation method for an automated terminal liner berth is proposed, the method comprising:

[0029] S100: The quay crane lane is divided into an operation lane 4 and a traffic lane 5, wherein the operation lane 4 is a lane occupied by the quay crane operation position, and the traffic lane 5 is a lane occupied by the IGV 3 after leaving the quay crane operation position or heading to the quay crane 2 operation position;

[0030] S102: Setting a lock pin channel 6, wherein the lock pin channel 6 is used for lock pin operation and downshifting;

[0031] S104: the IGV 3 whose lock pin needs to be removed or installed turns from the traffic lane 5 and vertically passes through the lock pin channel 6 to shift down;

[0032] S106: The IGV 3 that does not need to disassemble or assemble the locking pin turns from the traffic lane 5 and passes through the neutral area 7 to shift down. The neutral area 7 is arranged between the locking pin channel 6 and the quay crane 2.

[0033] In an automated terminal, the operating area can be divided into the following parts:

[0034] Frontier operation area: Mainly operates quay crane 2, light bridge and barges, among which liner berth operates liner, light bridge berth operates barge, gantry crane berth operates barge.

[0035] Up and down gear channels: IGV3 enters and leaves the front working area through the up and down gear channels.

[0036] Yard area: divided into full container yard area and empty container yard area, used for stacking containers.

[0037] In this embodiment, Figure 2, when a large liner is in operation, after the ship 1 docks at the front coast, there are usually 4-5 shore cranes 2 operating at the same time. At this time, the traffic flow of IGV3 is large. There are 6 lanes from WQ101 to WQ106 from the sea side to the road side shore crane lanes at the front. Among them, WQ101 (lane 1), WQ103 (lane 3), and WQ105 (lane 5) are working lanes 4, and WQ102 (lane 2) and WQ104 (lane 4) are passing lanes 5. After IGV3 shifts up through the upshift lane, it turns into lane 2 or lane 4, and then turns into lanes 1, 3, and 5 for operation. After the operation is completed, it turns into lanes 2 and 4 to leave. Therefore, the traffic flow in lanes 2 and 4 is very dense, which is easy to cause queues and congestion. After shifting up and before downshifting, IGV3 needs to switch between working lane 4 and passing lane 5. In order to improve the efficiency of upshifting and downshifting, the passing lane 5 and the working lane 4 are separated from each other, so that crossing multiple lanes can be avoided when switching.

[0038] After the IGV3 operation is completed, it will be downshifted. During the downshifting process, some IGV3s need to disassemble and install the lock pins, so they need to enter the downshift channel vertically and park to perform the lock pin operation. Combined with the turning radius of IGV3, the interval between the upshift channel and the downshift channel and the quay crane 2 must be greater than 29 meters. This leaves a gap area 7 between the downshift channel of the quay crane 2 and the quay crane 2. At the same time, if there is a large gap between the quay cranes 2 in liner operation, there will also be a gap area 7 between the quay cranes 2 at this time. If the IGV3 operating in the 5th lane is allowed to pass through the 6th lane and directly leave the quay crane 2 from this area, the traffic pressure on the 4th lane of the quay crane 2 will be reduced, and the number of downshift channels that need to be opened can also be reduced.

[0039] Some IGV3 do not need to remove or install the lock pin during the downshift process, such as empty vehicles and heavy vehicles that do not need lock pin operation. This type of IGV3 can pass through the neutral area 7. Because there is no need to arrange manual removal of the lock pin, when the IGV3 passes through this channel, it does not need to enter vertically, but turns into the neutral area in a certain arc trajectory and then enters the yard.

[0040] The up and down channels of the wharf are also called the locking channel 6 and the non-locking channel. IGV3 goes from the yard to the front area and leaves from the front area through this channel, and determines whether it needs to stay in the channel for locking operations according to its own task situation.

[0041] In some embodiments, the state of the lock pin channel 6 can be divided into an open state and a closed state, such as Figure 3 The lock pin channel 6 in the closed state will not be applied by IGV3, and the lock pin channel 6 in the open state can be applied by IGV3. The lock pin channel 6 of the liner is exclusive, that is, the lock pin channel 6 is bound to the liner, and only the IGV3 belonging to this liner task is allowed to pass through the lock pin channel 6 bound to this liner.

[0042] The lock pin channel 6 is composed of the IGV3 passage and the safety island arranged at intervals. The passage adopts a diamond shape as the IGV3 guide mark to guide the passage of IGV3, and a lock pin operation safety booth is placed on the safety island. There are lock pin operation workers in the safety island. When the IGV3 needs to be locked, the IGV3 will stay in the passage. The lock pin operation workers on the safety islands on both sides of the passage will disassemble and assemble the lock pins of the IGV3. After completing the operation, they will press the completion button, and the IGV3 will start to leave the passage. If the IGV3 does not need a lock pin operation, the IGV3 will pass through the passage without stopping to shift up and down. The lock pin operation safety booth can be moved, and it is required to be placed when the passage is opened.

[0043] Because there are safety islands and workers who disassemble and install the lock pins on both sides of the opened lock pin channel 6, when IGV3 enters the lock pin channel 6, the body and path must enter the channel vertically and cannot invade the safety islands on both sides of the lock pin channel 6 to prevent harm to the workers.

[0044] Specifically, when IGV3 is operating at the liner berth, the operation tasks include disassembly and installation of locking pins and no need to disassemble and install locking pins. Taking the conventional 6-lane quay crane 2 as an example, when the idle area 7 meets the requirements for downshifting without disassembly and installation of locking pins, the IGV3 that has completed the operation in lane 5 will make a judgment and choose whether to continue working at the front or leave the channel and downshift. If it continues to work at other quay cranes 2 at the front, it will receive the new task planning path according to the original logic and go to other quay cranes 2. If it chooses to downshift, it will further determine whether the locking pin operation is required. If necessary, it will downshift from the 4th lane. If the locking pin operation is not required, it can leave from the channel of the idle area 7.

[0045] In some embodiments, it is proposed that a first down-shift passage 8 and a second down-shift passage 9 are provided in the neutral region 7. Figure 4, when the IGV3 operation is completed, if the locking operation is not required and the gear is downshifted from the neutral area 7, there are two situations at this time. When the direction of IGV3 after downshifting is opposite to the direction of the working lane 4, it enters from the entrance of the first downshift channel 8 and passes through the arc-shaped first downshift channel 8 to downshift. Because the length of IGV3 is long and the space of the neutral area 7 is limited, the arc shape is used when turning to reduce the space occupied by IGV3 when passing. When the direction of IGV3 after downshifting is the same as the direction of the working lane 4, the second downshift channel 9 is set in the neutral area 7. The second downshift channel 9 is in the opposite zigzag shape, that is, the clockwise direction of entering the second downshift channel 9 and exiting the second downshift channel 9 is opposite. At the same time, in order to avoid route conflicts of IGV3 in different directions after downshifting, the first downshift channel 8 is set at the nearest position of IGV3 downshifting. In this embodiment, when the direction of the working lane 4 of IGV3 is to the left, the first downshift channel 8 is set close to the working lane 4, and the second downshift channel 9 is set on the left side of the first downshift channel 8. Similarly, when the direction of the IGV 3 operating lane 4 is to the right, the shape diagram of the first downshift channel 8 and the second downshift channel 9 is a mirror image diagram when the direction of the IGV 3 operating lane 4 is to the left.
