[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0036] The embodiment of the present application provides a rail-mounted container gantry crane loading and unloading process system configuration method, and the method comprises:

[0037] One of two key parameters of the gantry crane is predetermined; and the other one of the two key parameters of the gantry crane is configured by designing the loading and unloading process system and taking the optimal loading and unloading efficiency as the configuration basis for different loading and unloading conditions.

[0038] The parameters affecting the loading and unloading efficiency of the gantry crane include the gantry crane span S, the gantry crane lifting height H, the trolley running speed V1, the lifting speed V2 of the spreader, the rated lifting capacity G, etc., wherein the gantry crane span S and the gantry crane lifting height H are the most critical, and therefore, in the embodiment, the two key parameters of the gantry crane are the gantry crane span S and the gantry crane lifting height H.

[0039] The loading and unloading conditions include that the arrival or sending of the number of uncoupled trains L is 1-5, that is, the arrival or sending of the number of uncoupled trains L=1, the arrival or sending of the number of uncoupled trains L=2, the arrival or sending of the number of uncoupled trains L=3, the arrival or sending of the number of uncoupled trains L=4, the arrival or sending of the number of uncoupled trains L=5, etc.

[0040] The operation space of the railway loading and unloading yard is generally narrow, and when arranging the operation space of the loading and unloading equipment (such as the reach stacker, the gantry crane, the truck, etc.), the related requirements of the railway building limit (such as the line spacing, etc.) need to be considered, and therefore, in the embodiment, the optimal loading and unloading efficiency is taken as the configuration basis under the premise of meeting the design specifications, so that the loading and unloading process system and the two key parameters of the gantry crane can be better matched with the above-mentioned several loading and unloading conditions.

[0041] The railway vehicle container can be loaded and unloaded to the yard for temporary storage or directly loaded and unloaded to the truck for transportation, but in actual operation, the truck transportation capacity is difficult to match the gantry crane loading and unloading capacity in real time, and therefore, in the embodiment, the yard temporary storage mode is preferred when the yard width is allowed.

[0042] In one of the embodiments, the predetermined key parameter of the portal crane is the lifting height H of the portal crane, and the H = 11 m; and the container yard stacking height C is determined as 1 layer.

[0043] Further, the design of the handling process system and the configuration of the other one of the two key parameters of the portal crane specifically include:

[0044] 1) when L = 1

[0045] ① as Figure 1 , if the S = 24 m portal crane is selected, the handling line needs to be arranged in parallel outside the running rail considering the safety distance according to the design specification, and a maximum of 2 rows of container positions can be arranged in the yard within the span, and 1 row of vehicles can be handled to the yard. The transverse running distance of the portal crane trolley between the handling line and the center line of the yard is: 5 + 3 + 10.5 + 3.75 = 22.25 m;

[0046] ② as Figure 2 , if the S = 30 m portal crane is selected, the handling line can be arranged within the span of the portal crane, a maximum of 3 rows of container positions can be arranged in the yard within the span, and 1 row of vehicles can be handled to the yard. The transverse running distance of the portal crane trolley between the handling line and the center line of the yard is: 3 + 10.5 + 4.25 = 17.75 m.

[0047] Therefore: when L = 1, it is preferred to configure the portal crane span S as 30 m, and the handling process system includes: the handling line is arranged within the span of the portal crane, a maximum of 3 rows of container positions can be arranged in the yard within the span, and 1 row of vehicles is handled to the yard. Based on the configuration of the process system, the portal crane trolley running distance is shorter, and the handling efficiency is higher.

[0048] 2) when L = 2

[0049] If the S = 24 m portal crane is selected, the handling line needs to be arranged in parallel outside the running rail, a maximum of 2 rows of container positions can be arranged in the yard within the span, and 2 rows of vehicles are handled to the yard.

[0050] If the S = 30 m portal crane is selected, the handling line can be arranged within the span of the portal crane, a maximum of 3 rows of container positions can be arranged in the yard within the span, and 2 rows of vehicles are handled to the yard.

[0051] Therefore:

[0052] When L = 2, similarly to when L = 1, when L = 2, the portal crane span S is configured as 30 m, and the handling process system includes: the handling line is arranged within the span of the portal crane, a maximum of 3 rows of container positions can be arranged in the yard within the span, and 2 rows of vehicles are handled to the yard. Based on the configuration of the process system, the portal crane trolley running distance is shorter, and the handling efficiency is higher.

[0053] 3) when L = 3

[0054] If S = 24m gantry crane is selected, 2 rows of container positions can be arranged in the cross, 2 rows of vehicles can be loaded and unloaded to the yard, and 1 row of vehicles needs to be directly loaded and unloaded to the truck (1 box / vehicle) for transportation. At this time, the total time consumption of loading and unloading operation also needs to consider the interval time of truck to and from (additional time consumption t1 = 30 * (5-3) min = 60 min = 1h needs to be added).

[0055] If S = 30m gantry crane is selected, 3 rows of container positions can be arranged in the cross, and 3 rows of vehicles can be loaded and unloaded to the yard.

[0056] Therefore:

[0057] When L = 3, the gantry crane span S is configured to be 30m, and the loading and unloading process system comprises: the loading and unloading line is arranged in the gantry crane cross, 3 rows of container positions can be arranged in the cross, and 3 rows of vehicles can be loaded and unloaded to the yard. In this way, about 1h of truck interval time can be saved, and the total arrangement width is 30m, which is only slightly larger than the total arrangement width 29m of the loading and unloading process system with S = 24m.

[0058] 4) When L = 4

[0059] If S = 24m gantry crane is selected, the truck needs to simultaneously satisfy the loading and unloading of at least 2 rows of vehicles.

[0060] If S = 30m gantry crane is selected, 3 rows of vehicles can be loaded and unloaded to the yard, and 1 row of vehicles needs to be directly loaded and unloaded to the truck (1 box / vehicle) for transportation.

[0061] As Figure 3 , if S = 35.5m gantry crane is selected, 5 rows of container positions can be arranged in the cross, and 4 rows of vehicles can be loaded and unloaded to the yard.

[0062] Therefore, when L = 4, if the site construction condition is limited and there is a demand for direct loading and unloading truck transportation, the gantry crane span S is configured to be 30m, and the loading and unloading process system comprises: the loading and unloading line is arranged in the gantry crane cross, 3 rows of vehicles can be loaded and unloaded to the yard, and 1 row of vehicles is directly loaded and unloaded to the truck for transportation; if the site construction condition is not limited and there is no demand for direct loading and unloading truck transportation, the gantry crane span S is configured to be 35.5m, and the loading and unloading process system comprises: the loading and unloading line is arranged in the gantry crane cross, 5 rows of container positions can be arranged in the cross, and 4 rows of vehicles can be loaded and unloaded to the yard. Based on the above process system configuration, a higher loading and unloading efficiency can be obtained.

[0063] 5) When L = 5

[0064] If S = 24m or S = 30m gantry crane is selected, the truck needs to simultaneously satisfy the loading and unloading of at least 3 rows of vehicles or 2 rows of vehicles.

[0065] If S = 35.5 gantry crane is selected, 5 trains are loaded and unloaded to the yard.

[0066] Therefore:

[0067] When L = 5, the gantry crane span S is configured to be 35.5m, and the loading and unloading process system comprises: a loading and unloading line arranged in the gantry span, and the yard in the span can be arranged with a maximum of 5 rows of box positions, and 5 trains are loaded and unloaded to the yard. Based on the configuration of the above process system, higher loading and unloading efficiency can be obtained.

[0068] In one of the embodiments, the predetermined key parameter of the gantry crane is the gantry crane span S, and the S = 30m; and the container yard stacking column number N is determined to be 1 column.

[0069] Further, the design of the loading and unloading process system and the configuration of the other one of the two key parameters of the gantry crane specifically include:

[0070] 1) When L = 1

[0071] As Figure 4 , when L = 1, the gantry crane lifting height H is configured to be 11m, and the loading and unloading process system comprises: the box height is 2.591m, and 1 train is loaded and unloaded to the yard;

[0072] 2) When L = 2

[0073] Scheme : As Figure 5 , 1 column is loaded and unloaded in the yard.

[0074] When H = 11m, the clearance height is 11-2.591*2 = 5.818 > 2.591m, which meets the "stacking 2 over 3" spreader passing height requirement, and H = 11m can meet the lifting height requirement.

[0075] Scheme : As Figure 6 , 1 column is loaded and unloaded in the yard, and 1 column is directly loaded and unloaded in the truck transport. H = 11m can meet the lifting height requirement, but there is about 1h interval time of the truck for 1 column of 30 groups.

[0076] Therefore, when L = 2, the gantry crane lifting height H is configured to be 11m, and the loading and unloading process system comprises: 1 column 2 layer loading and unloading scheme in the yard, and 2 trains are loaded and unloaded to the yard; based on the configuration of the above process system, higher loading and unloading efficiency can be obtained.

[0077] 3) When L = 3

[0078] Scheme : As Figure 7 , 1 column is loaded and unloaded in the yard.

[0079] When H=11m, the clearance height is 11-2.591*3=3.227>2.591m, which meets the passing height requirement of the "stack 3 over 4" spreader, and H=11m can meet the lifting height requirement.

[0080] Scheme 2: as shown in Figure 8 , 1 layer and 2 columns are loaded and unloaded in the yard, and 1 column is directly loaded and unloaded in the truck transportation. H=11m can meet the lifting height requirement, but there is about 1h of truck interval time for 1 column of 30 groups.

[0081] Therefore, when L=3, the gantry crane lifting height H is configured to be 11m, and the loading and unloading process system comprises: 1 column and 3 layers of loading and unloading in the yard, and 3 columns of vehicles are loaded and unloaded to the yard; based on the above process system configuration, a higher loading and unloading efficiency can be obtained.

[0082] 4) when L=4

[0083] Scheme : 1 column and 4 layers of loading and unloading are carried out in the yard.

[0084] When H=11m, the clearance height is 11-2.591*4=0.636<2.591m;

[0085] When H=12.2m, the clearance height is 12.2-2.591*4=1.8.36<2.591m;

[0086] Therefore, neither H=11m nor H=12.2m meets the passing height requirement of the "stack 4 over 5" spreader.

[0087] As shown in Figure 9 , when H=13.5m, the clearance height is 13.5-2.591*4=3.136>2.591m, which meets the passing height requirement of the "stack 4 over 5" spreader, and H=13.5m can meet the lifting height requirement.

[0088] Scheme 2: as shown in Figure 10 , 1 layer and 3 columns are loaded and unloaded in the yard, and 1 column is directly loaded and unloaded in the truck transportation. H=11m can meet the lifting height requirement, but there is about 1h of truck interval time for 1 column of 30 groups.

[0089] Therefore, when L=4, the gantry crane lifting height H is configured to be 13.5m, and the loading and unloading process system comprises: 1 column and 4 layers of loading and unloading in the yard, and 4 columns of vehicles are loaded and unloaded to the yard; based on the above process system configuration, a higher loading and unloading efficiency can be obtained.

[0090] 4) when L=5

[0091] Scheme 1: 1 column and 5 layers of loading and unloading are carried out in the yard.

[0092] When H=15m, the clearance height is 15-2.591*5=2.045<2.591m, which does not meet the height requirement of the lifting appliance passing through;

[0093] As Figure 11 When H=16.2m, 16.2-2.591*5=3.245>2.591m, which meets the height requirement of the lifting appliance passing through "5 over 6", and H=16.2m can meet the lifting height requirement.

[0094] Scheme 2: As Figure 12 1 layer and 4 columns of loading and unloading are arranged in the yard, and 1 column is directly loaded and unloaded on the truck. H=13.5m can meet the lifting height requirement, but there is about 1h interval time of the truck for 1 column and 30 groups.

[0095] Therefore, when L=5, the lifting height H of the portal crane is configured as 16.2m, and the loading and unloading process system comprises: 1 column and 5 layers of loading and unloading in the yard, and 5 columns of trains are loaded and unloaded to the yard; based on the above process system configuration, a higher loading and unloading efficiency can be obtained.

[0096] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
