Problems solved by technology

Therefore, if the design of the heavy-duty railway technical operation station is arranged in short rows, the operation time of the train will be long, the capacity will be small, and the turnover of vehicles will be slow, which will seriously affect the transportation efficiency.
Instead, according to the transportation organization characteristics of heavy-haul railways, it is necessary to improve operating efficiency and make the layout of station facilities more convenient and applicable, so the standard station type of ordinary railways cannot be copied.

Embodiment 1

[0051] Example 1: Harness structure design of "2 wire clips and 1 machine travel" in the heavy-duty railway yard

[0052] like figure 1 and figure 2 As shown, the heavy-duty railway technical operation station yard of the present invention has a simple structure of "2 lines clamping 1 machine walking" wiring harness layout, including arrival and departure lines, locomotive running lines and 3 sets of waist forks. figure 1 is the operation situation of four 5000t unit trains, figure 2 It is the operation situation of two 10000t unit trains. After the first 5,000t or 10,000t heavy train is connected to the front of the departure line, the locomotive is off-hook and enters the standby line via the locomotive running line to wait for shift or enter the section for preparation, and the train performs train inspection technical operations; subsequent 3 5000t trains or 1 train The 10000t trains are respectively connected to the departure line at intervals of 11 minutes for the s...

Embodiment 2

[0053] Example 2: Determination of the number of wiring harnesses

[0054] refer to Figure 5 , the line speed and the number of departure lines can be determined according to the following formula according to the locomotive coupling mode of the heavy-haul train in Table 1 and the operation process and operation time of the heavy-haul train in Table 2.

[0055] M=(N 1 *210+N 2 *144) / [(1440-T 窗 )*(1-r 空 )]

[0056] M—the number of hair lines;

[0057] N 1 - Number of 5000t trains;

[0058] N 2 - Number of 10000t trains;

[0059] T 窗 —Skylight time, comprehensive maintenance skylight time should not be less than 90 minutes for a single line, not less than 120 minutes for a double line, and not less than 180 minutes when large-scale road maintenance machinery is used for maintenance.

[0060] r 空 — Empty cost coefficient, take 0.15-0.2.

[0061] According to the current operation experience of heavy-haul railways such as Daqin Line and Shuohuang Line, each combinati...

Embodiment 3

[0062] Example 3: setting of waist fork

[0063] like figure 1 , figure 2 , 5000t trains are combined into 20000t trains to set up three waist forks between the arrival and departure lines, and the effective length of the arrival and departure lines from the throat area to the waist forks and between the waist forks should meet the needs of the receiving and dispatching unit trains. As for the number of waist forks between the arrival and departure lines of a 10000t train combined into a 20000t train, it should be determined in conjunction with the traction coupling mode of the 10000t train. When the locomotives of the 10,000t train are all in front of the train, the 20,000t train assembly is decomposed into the middle of the hairline harness, and one waist fork is installed; when the locomotive is connected in the middle of the 10,000t train, the 20,000t train assembly is decomposed into the middle of the hairline harness, and three waist forks are installed .

Abstract

The invention discloses a wire harness structure design of "2 wire clips and 1 machine travel" in a heavy-duty railway yard. The structure adapts to the transportation organization characteristics of heavy-duty railways, and meets the requirements of 5000t and 10000t trains combined into 20,000-ton long trains, or 20,000-ton trains The large columns are decomposed into short columns of 5000t and 10000t. Including heavy-duty train depot operation process and operation time, wiring harness structure, line speed quantity, waist fork setting and line spacing layout. The structure consists of two 2800m-long arrival and departure lines, one machine-running line and three sets of waist forks. It not only satisfies the conditions for changing locomotives on the side of the arrival and departure line, but also serves as a safe parallel approach for short trains to arrive and pick up cars, forming a wiring harness consisting of 2 arrival and departure lines and 1 locomotive routing, that is, "2 lines Clip 1 machine away" wiring harness simple structure layout pattern. The invention has a simple structure, can meet the two requirements of receiving and dispatching trains and shunting operations at the same time, further enriches and improves the vehicle flow organization of the heavy-duty railway transportation, and improves the transportation capacity and efficiency of the heavy-duty railway.

Description

technical field [0001] The invention relates to the technical field of design and application of heavy-duty railways, in particular to a simple wiring harness layout structure with "2 wire clips and 1 machine walk" in the yard of a heavy-duty railway technical operation station. Background technique [0002] Heavy-haul railway transportation technology is a recognized development direction of railway freight at home and abroad. Its improvement in the transportation capacity of bulk cargo such as coal and ore and its comprehensive economic benefits have been confirmed by actual transportation performance. With the successful construction and operation of heavy-haul railways such as the 400 million-ton Daqin Line, the 350-million-ton Shuohuang Line, and the new construction and operation of heavy-duty railways in the central and southern parts of Shanxi, China has accumulated certain experience in heavy-haul transportation operations. Compared with the advanced level of foreig...
