Description

Technical Field

[0001] The invention belongs to the technical field of urban rail transit lines, and in particular relates to a throat arrangement structure of a compact rail transit vehicle base. Background Art

[0002] The subway vehicle base is a logistics base to ensure the normal operation of the subway and an important part of the subway system project. Among them, the operation depot, maintenance depot, engineering garage and throat are the main components that bear the functions of the vehicle base. The main functions of the operation depot and maintenance depot are to undertake the parking, maintenance, inspection and repair of vehicles; the engineering garage is the place where the shunting engineering vehicles are stored, and the faulty vehicles are towed to the main line or the operation depot through the throat; the throat is a place where driving, washing and shunting operations are busy. One end of the throat is usually connected to the tracks in the depot, and the other end is connected to the main line. It is one of the most important areas of the entire vehicle base. Therefore, the layout of the throat has a great impact on operational safety, operational efficiency, land use, etc.

[0003] At present, urban land resources are becoming increasingly scarce, the land use of vehicle bases is often restricted, and the surrounding environment of vehicle bases is complex. As the design gradually deepens and the surrounding pipeline data is collected, its land use will be further affected, and it is necessary to consider optimizing the existing design.

[0004] Take the common throat layout of vehicle bases as an example, Figure 1 As shown in the figure, the scheme is a throat-shaped car wash, with the entry and exit lines parallel to the tracks in the operation depot. However, in the actual design process, there are often problems such as insufficient length of the entry and exit lines (the U-shaped groove setting affects the existing road), too large an angle between the entry and exit lines and the parking lot, and insufficient throat land.

[0005] Through analysis, the factors that limit the use of throat land are as follows: First, the length of the line of the entry and exit lines within the vehicle base is affected by the connection angle between the entry line 4 and the operation warehouse 1; second, due to the large line spacing between the car wash line 3 and the entry line 4, the distance required for the switch A10 and the switch A9 is farther; third, the car wash pull-out line after the switch A10 and the throat track range in front of the warehouse need to meet the limit safety requirements, and the position of the car wash pull-out line is affected by the connection angle between the entry line 4 and the operation warehouse 1; fourth, the switch A11 leading to the engineering garage needs to keep a certain distance from the curve or switch in the throat range in front of the warehouse, and at the same time, the switch A12 needs to keep a certain straight-line distance from the curve behind the switch, resulting in the need for the switch A1~A12 in the entire car wash range to be away from the operation warehouse 1. Therefore, it is necessary to optimize the layout of the plan to reduce the land use under the premise of meeting the vehicle base function. Summary of the invention

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0028] like Figure 2As shown, the present embodiment provides a throat arrangement structure of a compact rail transit vehicle base, including an operation depot 1, wherein the throat area of ​​the operation depot 1 is provided with an exit line 5 and an entry line 4, the exit line 5 and the entry line 4 are arranged in parallel, and one end of each of the exit line 5 and the entry line 4 is connected to the operation depot 1 at a multiple of a turnout angle. By setting the exit line 5 and the entry line 4 at a multiple of a turnout angle, the connection angle between the traditional exit and entry lines and the operation depot 1 is changed, and the length of the exit and entry lines is increased. At the same time, since the exit and entry lines are in a multiple angle relationship with the operation depot 1, a set of curves and a set of turnouts can be saved, and more optional schemes can be provided for the design of the exit and entry lines. A first crossover 13 is provided between the exit line 5 and the entry line 4, and the vehicle is realized by the first crossover 13. The vehicle switches between the exit line 5 and the entry line 4; a car wash line 3 is arranged outside the entry line 4, a car wash garage 2 is arranged on the car wash line 3, a first car wash pull-out line 8 and a second car wash pull-out line 11 are arranged at both ends of the car wash line 3, the end of the first car wash pull-out line 8 is connected to the entry line 4 through a first single crossover 9, and the second car wash pull-out line 11 is connected to the entry line 4 through a second single crossover 12, so as to realize the route conversion of the vehicle between the car wash line 3 and the entry line 4; an engineering vehicle pull-out line 6 is arranged outside the exit line 5, the end of the engineering vehicle pull-out line 6 is connected to the engineering garage 7, and the engineering vehicle pull-out line 6 is connected to the exit line 5 through a second crossover 14, so as to realize the route conversion of the vehicle between the engineering vehicle pull-out line 6 and the exit line 5. In this embodiment, the entrance and exit lines are connected to the operation library 1 with multiples of the turnout angle, which not only increases the length of the entrance and exit lines, reduces the cutting of the land, is conducive to the development of large areas, and is suitable for the current development direction of rail transit. At the same time, the change of the entrance and exit line angles provides more optional schemes for the design of the entrance and exit lines; and the multiples of the turnout angle are set to replace the curve function, reduce the use of curves, reduce the maintenance workload, and save turnouts and reduce engineering investment.

[0029] Optimally, the second car wash pull-out line 11 is connected to the car wash line 3 through a curved section 10, and the curve radius of the curved section 10 is not less than 150m. The angle of the second car wash pull-out line 11 can be adjusted through the curved section 10 so that it will not be too close to the throat area of ​​the operation warehouse 2, and the curved section 10 makes the second car wash pull-out line 11 and the car wash line 3 smoothly connected, so that the train can pass through the car wash line 3 more smoothly when entering the car wash garage 2 for operation.

[0030] A detailed implementation method, the first crossover 13 includes a fifth turnout A5, a sixth turnout A6, a seventh turnout A7, an eighth turnout A8 and a diamond crossover, the fifth turnout A5 and the eighth turnout A8 are located on the entry line 4, and the eighth turnout A8 is a left-opening turnout, the direction of the straight line after the turnout is consistent with the direction of the first crossover 13, the sixth turnout A6 and the seventh turnout A7 are located on the exit line 5, and the eighth turnout A8 on the entry line 4 changes the direction of the track entering the operation warehouse 1, and then the direction of the second single crossover 12 connected to the second car wash pull-out line 11 can be adjusted, so that the car wash line 3 deviates from the throat track direction, shortening the land used for the car wash line 3.

[0031] The second crossover 14 is located on the side of the first crossover 13 away from the operation warehouse 1, and the two single crossovers between the traditional exit line 5 and the engineering vehicle pull-out line 6 are changed into a group of crossovers, which reserves space for the turnouts on the exit and entry lines to retract toward the operation warehouse 1, so that the turnouts on the exit and entry lines can approach the operation warehouse 1 at the same time, compressing the throat length and saving the land of the vehicle base. Specifically, the second crossover 14 includes the third turnout A3, the fourth turnout A4, the eleventh turnout A11, the twelfth turnout A12 and a diamond crossover, the third turnout A3 and the eleventh turnout A11 are located on the exit line 5, and the fourth turnout A4 and the twelfth turnout A12 are located on the engineering vehicle pull-out line 6.

[0032] The first single crossover 9 includes a first turnout A1, a second turnout A2 and a crossover. The first turnout A1 is located on the entry line 4, and is a left-opening turnout, located on the side of the first cross crossover 13 away from the operation warehouse 1.

The tenth turnout A10 is located on one end of the second car wash pull-out line 11 close to the wash garage 2, and is a left-opening turnout. The curved section at the end of the car wash line is connected to the second car wash pull-out line 11 through the tenth turnout A10.

[0034] The main technical standards of this embodiment are:

[0035] 1. The yard line uses 50kg / m rails, and the access line uses 60kg / m rails;

[0036] 2. The yard line adopts 50kg / m, No. 7 single-opening turnout, the turnout a value is 11.194m, the turnout b value is 12.433m, and the frog angle is 8°7′48.37″; the minimum distance between the two ends of the turnout and the ends of the horizontal and vertical curves shall not be less than 5m; a straight rail connection shall be set between the two sets of turnouts, and the rail length shall not be less than 4.5m;

[0037] 3. The minimum curve radius of the parking lot line should not be less than R-150m. The minimum curve radius of the exit line, entry line and connecting line for type A vehicles should not be less than R-250m, and that for type B vehicles should not be less than R-200m;

[0038] 4. The car wash line should be a straight line within the length of one car before and after the car wash garage, and the effective length of the pull-out line should not be less than the sum of the total length of the train, the length of the shunting locomotive, and the 10m safety distance.

[0039] The vehicle entry and washing operation path in this example is as follows: Figure 3 As shown, the vehicle enters from the entry line 4, first passes through the eighth turnout A8, the ninth turnout A9, and the tenth turnout A10 in sequence, and enters the second car wash pull-out line 11. After the vehicle changes its driving direction at the second car wash pull-out line 11, it passes through the tenth turnout A10 and enters the car wash line 3. After entering the car wash garage 2 to complete the car washing operation, it enters the first car wash pull-out line 8. After the vehicle changes its driving direction at the first car wash pull-out line 8, it passes through the second turnout A2 and the first turnout A1 in sequence and enters the entry line 4, and then enters the operation warehouse 1 for storage.

[0040] In this example, the rescue path of the engineering vehicle entering the main line is as follows: Figure 4 As shown, the engineering vehicle drives out from the engineering garage 7, passes the twelfth turnout A12 and the eleventh turnout A11 in sequence, and then drives into the exit line 5 to the location of the faulty vehicle for rescue.

[0041] The throat layout structure of the compact rail transit vehicle base of this embodiment can not only meet all the functions and efficiencies of the conventional throat eight-shaped car wash, but also changes the connection angle between the entrance and exit lines and the operation warehouse compared with the traditional throat layout, and increases the length of the entrance and exit lines by about 60m; in addition, this implementation case is drawn according to the 6-car formation of Type B cars, with a total train length of about 120m, which shortens the throat length by about 39.9m and saves about 13,833.6㎡ of land area on one side.

[0042] The above examples are merely illustrative of the present invention and do not constitute a limitation on the protection scope of the present invention. All designs that are the same or similar to the present invention fall within the protection scope of the present invention.
