Abstract
Description
Technical Field
[0001] The utility model belongs to the field of rail transportation, and in particular relates to magnetic levitation transportation. Background Art
[0002] Maglev transportation is a form of rail transportation. Maglev vehicle technology is a technology that uses magnetic force to overcome gravity to levitate objects, and is an important achievement of modern science and technology. Compared with traditional rail vehicles, maglev vehicle technology has the advantages of higher speed and stability, less noise and vibration, and lower maintenance costs. Maglev transportation is usually used to connect high-speed rail stations, airports and other urban transportation hubs, and plays an important role.
[0003] Due to the limitations of early planning, in order to save land, the terminal of the maglev line is sometimes a large fixed building, such as a high-speed railway station building or ancillary buildings of the high-speed railway station, or a drop-off platform. In this case, the terminal usually adopts a single-track return, and the end of the track is no longer extended. For example, the Changsha Maglev Express has this structure. Figure 1 As shown in the figure, the terminal station of Changsha Maglev Express is Maglev High-speed Railway Station. The current status of the station is an elevated station with a single-track return. It is adjacent to Changsha South High-speed Railway Station, and the end of the track is Changsha South High-speed Railway Station. With the development of the city, the maglev lines planned in the early stage can no longer meet the needs, and the maglev lines usually need to be extended. Taking Changsha Maglev Express as an example, for this type of maglev terminal station, the end is a large fixed building. If the maglev line adopts a single-track return method, if it needs to be extended, it faces the following difficulties: 1. It needs to be transformed from a single line to a double line, and the maglev terminal station needs to suspend operation for about 1 year, which is a long interruption time; 2. The existing maglev terminal station needs to be transformed, which increases the construction cost; 3. The end of the maglev track is a large fixed building, which conflicts with the extension of the track to add a new line. The large fixed building needs to be demolished, which is difficult to construct and has high construction costs. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies and defects mentioned in the above background technology and provide a track extension structure of a maglev line with short construction time, low construction cost and low construction difficulty.
[0005] In order to solve the above technical problems, the technical solution proposed by the utility model is:
[0006] A track extension structure for a maglev line, wherein a maglev terminal of the maglev line is adjacent to a fixed building, the track structure inside the maglev terminal is a single-track track, the end of the single-track track faces the fixed building (i.e., the extension direction of the single-track track will pass through the fixed building), and the track structure outside the maglev terminal is a double-track track, and a first track of the double-track track is connected to the single-track track, the end of another second track of the double-track track is connected to the single-track track through a transition line, the first track is also provided with a first extension track through a first switch, and the second track is also provided with a second extension track through a second switch.
[0007] In the track extension structure, preferably, the transition line is arranged outside the maglev terminal station. The above arrangement makes the construction of the transition line more convenient and provides a larger construction space.
[0008] In the track extension structure, preferably, the intersection of the first turnout and the first track is located outside the maglev terminal. The above arrangement ensures that the construction position when the first track branches out from the first extension track is located outside the platform, which makes construction more convenient and provides a larger construction space. The first turnout can refer to the existing technology and is a conventional construction structure and construction method.
[0009] In the track extension structure, preferably, the intersection position of the second turnout and the second track is far away from the connection position of the transition line and the second track. The above arrangement ensures that the construction position when the second track branches out from the second extension track is located outside the platform, which makes the construction more convenient and has a larger construction space. At the same time, it can avoid the vehicle from switching tracks multiple times in a short period of time. The above second turnout can also refer to the existing technology and is a conventional construction structure and construction method.
[0010] In the above track extension structure, preferably, the first extension track and the second extension track are far away from the periphery of the fixed building. The track extension structure of the utility model can ensure that the construction of the first extension track and the second extension track does not conflict with the fixed building, the first extension track and the second extension track can be far away from the fixed building, and the first extension track and the second extension track can be arranged in parallel.
[0011] In the track extension structure, preferably, the first track or the second track is branched outside the maglev terminal station to form a vehicle segment connecting line, and the vehicle segment connecting line is connected to a vehicle stop section. The vehicle stop section is used for the parking of vehicles and vehicle maintenance.
[0012] Compared with the prior art, the advantages of the utility model are:
[0013] 1. The track extension structure of the maglev line of the utility model does not need to be constructed by a single-track to double-track construction method. Instead, a mature turnout is used to lead out the extended track. The extended track is branched out from the double-track track. The track connection project is simple, the implementation risk is small, the operation interruption time is only about 2 months, the station operation interruption time is short, and the overall feasibility is high.
[0014] 2. The main construction locations of the track extension structure of the maglev line of the utility model are all located outside the maglev terminal station, and there is no need to improve the maglev station. The construction cost is low and the impact on the overall line operation is small.
[0015] 3. The track extension structure of the maglev line of the utility model does not need to dismantle the fixed buildings near the maglev terminal station, and the construction difficulty is small and the construction cost is low. Especially for large fixed buildings, this advantage is more obvious.
[0016] In general, compared with the common practice of rail transit (extending the main line from the rear of the station), the track extension structure of the maglev line of the utility model can realize the extension function of the common practice of rail transit, reduce the difficulty of the project, reduce the impact on the maglev station and nearby fixed buildings, and has a short construction time, low construction difficulty and low construction cost.

[0026] Example:
[0027] like Figure 1 As shown in the figure, it is a schematic diagram of the layout of the Changsha Maglev Express Maglev High-speed Railway Station and Changsha High-speed Railway South Station. For this type of maglev express line, if the line is to be extended, the following methods are adopted Figure 2 As shown in the figure, it is a schematic diagram of the traditional track extension structure of Changsha Maglev Express at the Maglev High-speed Railway Station. It can only be done by demolishing the fixed building 2 and then changing the single line into a double line. The new line is as follows Figure 2 Shown by dotted line.
[0028] like Figure 3 As shown, the track extension structure of the maglev line of this embodiment, the maglev terminal station 1 of the maglev line is adjacent to the fixed building 2, the station track structure of the maglev terminal station 1 is a single-line track 3, the end of the single-line track 3 faces the fixed building 2, the station track structure of the maglev terminal station 1 is a double-line track, and a first track 4 in the double-line track is connected to the single-line track 3, the end of the other second track 5 in the double-line track is connected to the single-line track 3 through a transition line 6, the first track 4 is also led out through a first switch and provided with a first extension track 7, and the second track 5 is also led out through a second switch and provided with a second extension track 8.
[0029] In this embodiment, the transition line 6 is arranged outside the maglev terminal station 1 .
[0030] In this embodiment, the intersection position of the first switch and the first track 4 is located outside the maglev terminal station 1 .
[0031] In this embodiment, the intersection position of the second turnout and the second track 5 is far away from the connection position of the transition line 6 and the second track 5 .

[0034] This embodiment takes Changsha Maglev Express as an example to further illustrate the advantages of the track extension structure of the maglev line of this embodiment. Figure 2 The traditional construction method of extending the main line from the rear of the station requires the removal of the drop-off platform of Changsha South High-speed Railway Station and the reconstruction of the maglev high-speed railway station, which takes a long time and has high construction costs. Figure 3 The track extension structure of the maglev line of the present embodiment shown in only needs to be outside the maglev high-speed railway station, on the basis of the double-track track, and a set of single-opening turnouts are respectively used to lead out the first extension track 7 and the second extension track 8.

It has little impact on the Changsha Maglev Express, and the track connection project is simple. It only needs to insert the turnout in the section in front of the station, and the interruption time is short, and the feasibility is strong. Compared with the general practice of rail transit (main line behind the station), this extension method can realize the function of extending the general practice of rail transit, and can reduce the difficulty of the project and reduce the impact on the Changsha Maglev Express, with obvious advantages.
[0035] After the Changsha Maglev Express extension line is constructed using the track extension structure of the present embodiment, Figure 3 As shown by the arrow in the middle, the existing line ( Figure 3 The maglev vehicle heading to the maglev high-speed railway station (center right) passes through the first track 4 and enters the single-track 3 of the maglev high-speed railway station to stop. The maglev vehicle can turn back through the single-track 3 of the maglev high-speed railway station and then continue to move in the direction of the extended line through the transition line 6, the second track 5, the second turnout and the second extended track 8; similarly, the extended line ( Figure 3 After the maglev vehicle traveling toward the maglev high-speed railway station in the direction of the first extension track 7, the first switch, and the first track 4 enters the single-track 3 of the maglev high-speed railway station and stops, the maglev vehicle can turn back through the single-track 3 of the maglev high-speed railway station and then continue to travel in the direction of the existing line through the transition line 6 and the second track 5. The above track setting method can realize the extension of the line while ensuring that any track is only used by maglev vehicles in the same driving direction.
