Description

Technical Field

[0001] The invention relates to a layout structure of a rail transit system, and in particular to a plane layout structure of a rail transit field section suitable for a narrow and long plot of land. Background Art

[0002] Urban rail transit depot is a place where urban rail transit system vehicles are parked, maintained, regularly inspected and maintained.

[0003] The depot operation depot includes the biweekly / three-monthly inspection depot and the parking train inspection depot. The comprehensive maintenance depot includes the scheduled maintenance depot, temporary maintenance depot, wheel turning depot, purge depot, and static adjustment depot. Due to the limitations of terrain conditions and land use scope, the depot layout plan in the narrow and long plot is mostly arranged in the form of inverted maintenance depot. Figure 2 The pull-out line L6 and the running line L5 are arranged side by side on one side of the operation warehouse.

[0004] The normal vehicle maintenance route first comes out of the operation warehouse, enters the lead-out line L10, reverses to the lead-out line L6, and then changes direction to enter the maintenance warehouse line L4 before entering the maintenance warehouse. The whole process requires zigzag movement, changing direction twice, and stopping twice. The travel distance is long and the operation efficiency is low.

[0005] In the layout of the inverted vehicle depot, the pull-out line L6 and the running line L5 need to be arranged side by side on one side of the operation depot. The entire layout has certain requirements on the lateral distance of the narrow and long plot.

[0006] Based on the above analysis, the current layout of the inverted vehicle depot is not adaptable to narrow and long plots. The entire maintenance operation requires a long walking distance, and the zigzag walking operation efficiency is low.

[0007] Figure 1 This is the structural diagram of the inverted layout of the traditional rail transit vehicle depot; Figure 2 This is a schematic diagram of the movement of vehicles from the operation warehouse to the maintenance warehouse in the traditional rail transit vehicle depot inversion layout structure diagram. Figure 1 and Figure 2 As shown in the figure, the traditional inverted layout vehicle depot requires the following path for vehicles to move from the operation depot F1 to the maintenance depot F2: 1. First, the vehicle drives out of the operation depot F1 and enters the pull-out line L10 after passing the crossover line L9 and the single crossover line L7; 2. The vehicle passes through the turnout C13 and the turnout C8 to enter the ladder line L8, and passes through the turnout C9 and the turnout C10 to enter the pull-out line L6; 3. The shunting locomotive pushes the vehicle through the turnout C10 and the turnout C9, and enters the maintenance depot F2 through the maintenance entry line L4, and vice versa for leaving the depot. To complete the movement instruction between the two large depots, the vehicle needs to pass through the pull-out line twice, and needs to change direction twice on the pull-out line. The movement distance is long and the operation efficiency is low. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a plane layout structure of a rail transit section suitable for narrow and long plots of land, which has a reasonable layout structure, saves resources, improves production efficiency, and increases land utilization.

[0009] The technical solution adopted by the present invention is a planar layout structure of a rail transit yard suitable for a narrow and long plot of land, including an operation warehouse F1, a maintenance warehouse F2, a car wash F3 built in the narrow and long plot for use by rail transit vehicles, and intra-segment lines and switches connected to the operation warehouse F1, the maintenance warehouse F2, and the car wash F3; the operation warehouse F1 is arranged in a forward direction, the maintenance warehouse F2 is arranged in an inverted opposite direction through a maintenance entry line L4, and the locomotive running line L5 is arranged on the outside of the maintenance entry line L4; the car wash F3 is arranged in a through-type manner on the outside of the entry line L1, and both ends of the car wash line L3 are connected to the entry line L1 through a single-opening switch; the operation warehouse F1 and the maintenance warehouse F2 are respectively connected to the intra-segment lines and switches.

[0010] The entry line L1 and the exit line L2 are connected to the operation warehouse F1 in the forward direction through the crossover line L9; the pull-out line L6 is connected to the exit line L2 and the maintenance entry line L4 through the ladder line L8.

[0011] The effective length of the track from turnout C12 to turnout C11 in the maintenance storage line L4 is ≥ the sum of the length of a train, the length of the shunting locomotive and the safety distance; the effective length of the track from turnout C12 to turnout C9 in the locomotive running line L5 is ≥ the sum of the length of a train, the length of the shunting locomotive and the safety distance; the effective length of the track of the pull-out line L6 is ≥ the sum of the total length of the train passing through the pull-out line, the length of the shunting locomotive and the safety distance at the terminal of the pull-out line.

[0012] The maintenance entry line L4 is connected to the exit line L2 at a small mileage side via a single crossover line L7, and the maintenance entry line L4 is connected to the exit line L2 at a large mileage side via a ladder line L8 and then extends to the vehicle gear CD1.

[0013] The beneficial effects of the present invention are:

[0014] 1. The distance that vehicles travel to enter the maintenance depot is short, and the vehicles do not need to turn in a zigzag pattern, which greatly improves the efficiency of maintenance operations and the efficiency of operations and management.

[0015] 2. All tracks and shunting operations are optimally arranged between the operation depot and the maintenance depot. There are no tracks on the outside of the two depots, which makes them more adaptable to narrow and long plots and improves the utilization rate of the site.

[0016] 3. Compared with the traditional inverted layout, the track laying and turnout laying in the yard section are reduced, and the corresponding engineering quantities of roadbed, water supply and drainage, contact network (track), communication, electricity and other related specialties caused by track laying and turnout laying are reduced. The process is smooth, the operation efficiency is high, the cost is reduced, and the land utilization rate is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0026] The terms involved in this application are explained as follows:

[0027] Track - refers to the track for locomotives and vehicles to run;

[0028] Outbound line – the line for trains to be transported from the vehicle base to the connection station;

[0029] Entry line - the line for trains to be transported from the connection station to the vehicle base; the specification stipulates that both the exit line and the entry line can be used in both directions, and the exit line and the entry line are collectively referred to as the entry and exit lines;

[0030] Car wash line – a line that enables trains to enter a car wash garage for washing;

[0031] Turnout - a device that allows a railway to be divided into two or more lines;

[0032] Train stop - a device at the end of a line to prevent a train or vehicle from moving;

[0033] Single crossover - the track used for transfer when a train switches from one track to another.

[0034] Crossover - a track device in which two single crossovers overlap and intersect to facilitate train transfers between two adjacent lines.

[0035] Ladder line - connecting several parallel lines to a common line is called a ladder line.

[0036] Pull-out line - the pull-out track used for vehicle marshaling or dismantling and shunting operations.

[0037] Effective length of line refers to the portion of the line where locomotives and vehicles can be parked without obstructing traffic on adjacent lines.

[0038] like Figure 3 As shown, the present invention is a planar layout structure of a rail transit yard suitable for a narrow and long plot, including an operation warehouse F1, a maintenance warehouse F2, a car wash F3 built in the narrow and long plot for rail transit vehicles, and the lines and switches connected to the major warehouses. The car wash F3 is arranged in a through-type manner outside the entry line L1, and the two ends of the car wash line L3 are connected to the entry line through single-opening switches C1 and C2. The operation warehouse F1 is arranged in a forward direction, and the entry and exit lines are connected to the operation warehouse F1 in a forward direction through the crossover L9. The maintenance depot is arranged in an inverted opposite manner through the maintenance entry line L4, and the locomotive running line L5 is arranged on the outside of the maintenance entry line L4, and is connected to the maintenance entry line L4 through turnouts C9 and C12; the maintenance entry line L4 is connected to the small mileage side of the exit line L2 through a single crossing line L7, and the maintenance entry line L4 is connected to the large mileage side of the exit line L2 through a ladder line L8 and then extends to the vehicle stop CD1; the pull-out line L6 is connected to the exit line L2 and the maintenance entry line L4 through the ladder line L8.

[0039] The crossover L9 includes: turnout C3, turnout C4, turnout C5, turnout C6 and diamond crossover; the single crossover L7 includes: turnout C10, turnout C11 and single crossover; the ladder line L8 includes: turnout C7, turnout C8 and ladder line.

[0040] There is no overhead contact network or contact rail in the regular maintenance depot, large driving maintenance depot and temporary maintenance depot in the comprehensive maintenance depot. When vehicles enter the above maintenance depots from the operation depot, they need a shunting locomotive to provide power. The following descriptions are all based on the example of vehicles entering a non-electrified maintenance depot.

[0041] like Figure 4As shown, the vehicle needs to follow the following path from the operation depot F1 to the maintenance depot F2: 1. First, the vehicle exits the operation depot F1 and enters the entry line L1, passes through the turnouts C5 and C6 in the crossover line L9 and enters the exit line L2 (or the vehicle exits the operation depot F1 and directly enters the exit line L2); 2. The vehicle passes through the turnouts C10 and C11 in the single crossover line L7 and enters the maintenance entry line L4, waiting for the shunting locomotive; 3. After the shunting locomotive passes through the turnout C12 and enters the locomotive running line L5, it passes through the turnout C9 and enters the maintenance entry line L4. The shunting locomotive changes direction and pushes the vehicle into the maintenance depot through the turnouts C9, C11, and C12. (The vehicle only needs to go through the above steps 1 and 2 to enter the electrified maintenance depot directly.)

[0042] The vehicle needs to follow the following path when entering the operation depot F1 from the maintenance depot F2: 1. The shunting locomotive enters the maintenance depot and pulls the vehicle to the maintenance depot entry line L4. After the locomotive and vehicle pass through the switch C12, the shunting locomotive passes through the switches C11 and C9 to exit the maintenance depot entry line L4; 2. The vehicle passes through the switches C11 and C10 in the single crossover L7 to enter the exit line L2; 3. The vehicle passes through the switches C6, C4, and C7 to enter the operation depot F1; or the vehicle passes through the switches C6 and C5 in the crossover L9 to enter the entry line L1 and enter the operation depot F1. (The vehicle needs to go through the above steps 1, 2, and 3 to exit the electrified maintenance depot and directly enter the operation depot without the need for shunting locomotive traction.)

[0043] The effective length of the car washing line L3 of the present invention before and after the car washing garage F3 meets the effective length requirement of car washing, and the effective length of car washing includes the length of a train and the additional length for setting up the signal equipment; the effective length of the track from turnout C12 to turnout C11 in the maintenance storage line L4 meets the requirement of not less than the sum of the length of a train, the length of the shunting locomotive and the safety distance; the effective length of the track from turnout C12 to turnout C9 in the locomotive running line L5 meets the requirement of not less than the sum of the length of a train, the length of the shunting locomotive and the safety distance; the effective length of the track of the lead-out line L6 is not less than the sum of the total length of the train passing through the lead-out line, the length of the shunting locomotive and the safety distance at the lead-out line terminal.

[0044] In the embodiments of the present invention, different urban rail transit forms have different requirements for effective length, safety distance, curve radius and turnout. The present invention focuses on providing a layout structure that can be adopted by rail transit sections of various types.

[0045] The curves and turnouts shown in the figure of the present invention meet the requirements of the corresponding rail transit specifications. (For example, the curve radius of the section applicable to subway A and B type vehicles is not less than 150m, and the turnout adopts 50-track No. 7 turnout.)

[0046] It is worth pointing out that the protection scope of the present invention is not limited to the above-mentioned specific examples. According to the basic technical concept of the present invention, the purpose of the present invention can also be achieved with basically the same structure. As long as ordinary technicians in this field can think of any implementation method without creative work, it belongs to the protection scope of the present invention.
