Description

Technical Field

[0001] This application relates to the field of rail transit technology, and in particular to a turnout and a rail transit system. Background Technology

[0002] In related technologies, turnouts feature a movable beam positioned between two fixed beams. A drive mechanism moves the movable beam between the two fixed beams to switch between different traffic lanes. However, because the movable beam is a single unit, it is large, heavy, and inflexible in its movement. Summary of the Invention

[0003] This application aims to at least partially address one of the technical problems in the related art.

[0004] Therefore, one objective of this application is to provide a turnout whose movable beam can respond to control commands more quickly and whose frictional energy consumption during movement is reduced.

[0005] This application also proposes a rail transit system with the aforementioned turnouts.

[0006] According to this application, a turnout includes at least one individual turnout, the individual turnout comprising: a fixed beam, the fixed beam comprising: a first side beam and a second side beam disposed opposite to each other; a movable beam, the movable beam being movably disposed between the first side beam and the second side beam to define two switchable traffic lanes; and a drive device connected to the movable beam to drive the movable beam to move relative to the fixed beam, the drive device being configured as a magnetic drive device to drive the movable beam to move between the first side beam and the second side beam by magnetic force.

[0007] According to the turnout of this application, the movable beam is driven to move between the first side beam and the second side beam by a magnetic drive device, thereby responding to control commands more quickly. At the same time, the magnetic drive can greatly reduce the friction force received by the movable beam, which not only reduces power consumption, but also improves the response speed of the movable beam.

[0008] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0021] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0022] The following is for reference. Figure 1-5 This application describes a turnout according to an embodiment of the present application.

[0023] The turnout according to the embodiments of this application includes at least one individual turnout; that is, the turnout may include one or more individual turnouts. When the turnout is composed of multiple individual turnouts, the individual turnouts constituting one turnout have the same structure.

[0024] Specifically, the turnout according to the embodiments of this application can be used in a rail transit system, so that a rail transit system equipped with the turnout can have the same advantages as the turnout.

[0025] According to an embodiment of this application, a single turnout includes a fixed beam, a movable beam, and a drive device. The fixed beam includes a first side beam 111 and a second side beam 112 disposed opposite to each other. The movable beam is movably disposed between the first side beam 111 and the second side beam 112 to define two switchable travel channels. The top surface of the movable beam is constructed as a first running surface for the travel wheels of the rail vehicle to travel on. The first side beam 111 is a straight rail and extends along a straight line, while the second side beam 112 is an arc-shaped rail and extends along an arc. The distance between the second side beam 112 and the first side beam 111 can gradually increase in the direction of travel of the rail vehicle. Both the first side beam 111 and the second side beam 112 are arc-shaped rails, and the first side beam 111 and the second side beam 112 can extend along a set of symmetrical curves respectively so that the single turnout constitutes a split turnout.

[0026] The movable beam can define a first travel channel between itself and the first side beam 111. After the movable beam moves to a new position, it can define a second travel channel between itself and the second side beam 112. It should be noted that the top surfaces of the first side beam 111 and the second side beam 112 are designed as running surfaces for rail vehicles. The two sets of running wheels on the rail vehicle can travel on the top surfaces of the movable beam and the first side beam 111, or on the top surfaces of the movable beam and the second side beam 112, respectively.

[0027] The rail vehicle is equipped with bogies 230, and the bogies 230 are equipped with running wheels 210 and guide wheels 220. Each car is equipped with two bogies 230, and the two bogies 230 are spaced apart in the extension direction of the running lane.

[0028] Specifically, each bogie 230 has two running wheels 210 spaced apart in the width direction of the travel aisle, and four guide wheels 220, two of which are spaced apart in the width direction of the travel aisle, and the other two are spaced apart in the width direction of the travel aisle and spaced apart from the aforementioned two guide wheels 220 in the extension direction of the travel aisle.

[0029] The rotation axis of the traveling wheel 210 can extend horizontally, and the rotation axis of the guide wheel 220 can extend vertically. After defining the first travel channel between the movable beam and the first side beam 111, the two traveling wheels 210 roll on the top surface of the first side beam 111 and the top surface of the movable beam, respectively, and the two sets of guide wheels 220 roll on the sides of the first side beam 111 and the movable beam that are directly opposite each other. After defining the second travel channel between the movable beam and the second side beam 112, the two traveling wheels 210 roll on the top surface of the movable beam and the top surface of the second side beam 112, respectively, and the two sets of guide wheels 220 roll on the sides of the movable beam and the second side beam 112 that are directly opposite each other.

[0030] The first side beam 111 and the second side beam 112 do not intersect or overlap and both extend along the direction of travel of the rail vehicle. Since the rail vehicle can choose different directions of travel at the individual turnout, the first side beam 111 and the second side beam 112 can extend along different directions of travel respectively. The movable beam can move between the first side beam 111 and the second side beam 112, and during the movement of the movable beam, the individual turnout can present two travel lanes, each of which guides the rail vehicle in a different direction. Moreover, at any given time, only one of the two travel lanes can be used by the rail vehicle, thus indicating that the two travel lanes are switchable.

[0031] The drive device is connected to the movable beam to drive the movable beam to move relative to the fixed beam. The drive device can serve as a power source to provide power for the movement of the movable beam. In the embodiments of this application, the drive device is constructed as a magnetic drive device, which can drive the movable beam to move between the first side beam 111 and the second side beam 112 by magnetic force.

[0032] Therefore, in the turnout of this application embodiment, the movable beam is driven to move between the first side beam 111 and the second side beam 112 by a magnetic drive device, so that the control command can be responded to more quickly. At the same time, the magnetic drive can greatly reduce the friction force received by the movable beam, which not only reduces power consumption, but also improves the response speed of the movable beam.

[0033] In some embodiments of this application, the magnetic drive device 150 may include a magnetic pole base 151, a conductive wire group 152, and a connecting bracket 153.

[0034] The magnetic pole base 151 can extend roughly along the direction of movement of the movable beam. The magnetic pole base 151 can be constructed as a permanent magnet or an electromagnet, as long as the magnetic pole base 151 has magnetic field lines.

[0035] The conductive wire group 152 is disposed within the magnetic field space 103 of the magnetic pole base 151. When the conductive wire group 152 is energized, a driving force is generated because the conductive wire group 152 is disposed within the magnetic field space 103 of the magnetic pole base 151.

[0036] One end of the connecting bracket 153 is connected to the movable beam, and the other end of the connecting bracket 153 is connected to the conductive wire group 152. After the conductive wire group 152 is energized, the wire group located in the magnetic field line space 103 will generate a driving force. This driving force can drive the connecting bracket 153 and the movable beam connected to the connecting bracket 153 to move between the first side beam 111 and the second side beam 112.

[0037] In addition, the direction of the driving force can be changed by changing the current flow direction in the conductive wire group 152. For example, when the current in the conductive wire group 152 is positive, the driving force generated at this time will drive the movable beam to move towards the first side beam 111; at this time, the current in the conductive wire group 152 can be changed to be negative, and the driving force generated at this time can drive the movable beam to move towards the second side beam 112.

[0038] Furthermore, a guide assembly is provided between the magnetic pole base 151 and the connecting bracket 153, which allows the connecting bracket 153 to move along a preset direction on the magnetic pole base 151. For example, the guide assembly allows the connecting bracket 153 to move along the extension direction of the magnetic pole base 151.

[0039] Specifically, the guide assembly may include a first roller 154a, a second roller 154b, a first guide surface 104, and a second guide surface 105.

[0040] The first roller 154a and the second roller 154b are respectively disposed on opposite sides of the other end of the connecting bracket 153, and the rotation axes of the first roller 154a and the second roller 154b extend in the vertical direction. The first guide surface 104 and the second guide surface 105 are respectively disposed on opposite sides within the magnetic field line space 103. That is, the magnetic pole base 151 is provided with a magnetic field line space 103, and the first guide surface 104 and the second guide surface 105 are disposed on opposite sides within the magnetic pole base 151.

[0041] The first roller 154a is rotatably mounted on the first guide surface 104, and the second roller 154b is rotatably mounted on the second guide surface 105. The first guide surface 104 and the second guide surface 105 extend in the same direction. This allows the movable beam to move under the drive of the connecting bracket 153.

[0042] In the embodiments of this application, the magnetic pole base 151 includes a bottom wall 151a, a top wall 151b, a first side wall 151c, and a second side wall 151d. The bottom wall 151a and the top wall 151b are directly opposite each other and spaced apart in the vertical direction. The first side wall 151c and the second side wall 151d are directly opposite each other and spaced apart in the horizontal direction. The first side wall 151c is connected to one end of the bottom wall 151a and the top wall 151b on the same side, and the second side wall 151d is connected to the other end of the bottom wall 151a and the top wall 151b on the same side. The bottom wall 151a, the top wall 151b, the first side wall 151c, and the second side wall 151d together define a magnetic field line space 103. A first guide surface 104 and a second guide surface 105 are respectively provided on the sides of the first side wall 151c and the second side wall 151d that are directly opposite each other.

[0043] Furthermore, a guide groove 106 is provided on the top wall 151b for the connecting bracket 153 to pass through. The guide groove 106 can extend along the extension direction of the magnetic pole base 151, thereby avoiding the connecting bracket 153 when the driving force generated by the conductive wire group 152 drives the connecting bracket 153 to move.

[0044] In some embodiments of this application, the turnout further includes a first guide rail 131, which is constructed as a linear guide rail. The first guide rail 131 is disposed below the moving beam 122, and the moving beam 122 can move along the first guide rail 131. Since the rotating beam 121 rotates around the rotation center 101, and the first guide rail 131 is a linear guide rail, the minimum distance between the rotating part of the rotating beam 121 and the first guide rail 131 changes during rotation. Simultaneously, the moving beam 122 moves along a preset path K1 on the first guide rail 131.

[0045] The movable beam 122 can maintain the same motion trajectory as the other end of the rotating beam 121 to form an arc-shaped preset path, and the movable beam 122 can move along the preset path K1.

[0046] Simultaneously, the movable beam 122 can move on the first guide rail 131. The trajectory of the end of the movable beam 122 connected to the rotating beam 121 is arc-shaped. To ensure that the movable beam 122 does not interfere with the first guide rail 131, for example, the movable beam 122 can move in a direction parallel to the extension direction of the first guide rail 131, and also in a direction orthogonal to the extension direction of the first guide rail 131. The trajectory of the movable beam 122 is obtained by combining the trajectory of the movable beam 122 in the extension direction of the first guide rail 131 and the trajectory of the movable beam 122 in the direction orthogonal to the extension direction of the first guide rail 131. Thus, as... Figure 1 As shown, the movement trajectory of the moving beam 122 is also arc-shaped, that is, the preset path K1 for the movement of the moving beam 122 is an arc-shaped path.

[0047] In some embodiments of this application, the turnout further includes a first movable component disposed between the first guide rail 131 and the movable beam 122. The first movable component is disposed between the first guide rail 131 and the movable beam 122, and the first movable component can move along the first guide rail 131 in a first direction, while the movable beam 122 is movably disposed on the first movable component and moves relative to the first movable component in a second direction, the first direction and the second direction having an included angle.

[0048] It is understandable that the first direction is the same as the extension direction of the first guide rail 131, the second direction is orthogonal to the first direction, and the angle between the first direction and the second direction is 90°.

[0049] Furthermore, the first moving component is provided with a first sliding member 141 extending along the second direction, and the moving beam 122 is provided with a second sliding member, with the first sliding member 141 and the second sliding member slidingly engaged.

[0050] Specifically, the first slider 141 is constructed as a slide rail or slide groove and extends along the second direction, while the second slider is constructed as a slider and is disposed on the moving beam. Thus, during the movement of the moving beam 122, the slider can move together with the first slider 141 in the first direction, and simultaneously move along the slide rail or slide groove in the second direction.

[0051] A first rotating wheel 161 is provided below the first sliding member 141. The first rotating wheel 161 can roll on the top surface of the first guide rail 131. There can be multiple first rotating wheels 161, and multiple first rotating wheels 161 can be arranged sequentially along the length of the first guide rail 131.

[0052] In some embodiments of this application, the turnout further includes a second guide rail 132, which is constructed as a linear guide rail. The second guide rail 132 is disposed below the moving beam 122, and the moving beam 122 can move along the second guide rail 132. The second guide rail 132 not only guides the moving beam 122 but also supports it, thereby improving the moving stability of the moving beam 122.

[0053] Furthermore, the turnout also includes a second moving component, which is disposed between the second guide rail 132 and the moving beam 122. The second moving component can move along the second guide rail 132 in a third direction, and the moving beam 122 is movably disposed on the second moving component and moves relative to the second moving component in a fourth direction, with the third direction and the fourth direction having an included angle.

[0054] It is understandable that the third direction extends in the same direction as the second guide rail 132, and the fourth direction can be orthogonal to the third direction, with an angle of 90° between them.

[0055] In the embodiments of this application, the first guide rail 131 and the second guide rail 132 are arranged in parallel, so the first guide rail 131 and the second guide rail 132 extend in the same direction. The first direction and the third direction are the same, while the second direction is orthogonal to the first direction and the fourth direction is orthogonal to the third direction. Therefore, the second direction and the fourth direction are the same.

[0056] Furthermore, the second moving component is provided with a third sliding member 142 extending in the fourth direction, and the moving beam 122 is provided with a fourth sliding member, with the third sliding member 142 and the fourth sliding member slidingly engaged.

[0057] Specifically, the third slider 142 is constructed as a slide rail or slide groove and extends in the fourth direction. The third slider 142 is disposed on the second moving assembly, and the fourth slider is constructed as a slider and disposed on the moving beam 122. Thus, during the movement of the moving beam 122, the slider can move upward in the third direction while simultaneously moving in the fourth direction along the slide rail or slide groove.

[0058] A second rotating wheel 162 is provided below the third sliding member 142. The second rotating wheel 162 can roll on the top surface of the second guide rail 132. There can be multiple second rotating wheels 162, which can be arranged sequentially along the length of the second guide rail 132.

[0059] In some embodiments of this application, a mounting plate 160 may be provided between the first sliding member 141 and the third sliding member 142, and the mounting plate 160 may be connected to one end of the connecting bracket 153.

[0060] The rail transit system according to this application also includes a rail vehicle 200, which can move on the track. The rail vehicle 200 is provided with running wheels 210 and guide wheels 220. The running wheels 210 can be in two sets and roll on the top surfaces of the first side beam 111 and the movable beam respectively, or on the top surfaces of the movable beam and the second side beam 112 respectively. The guide wheels 220 are also in two sets and are adapted to roll on the sides of the first side beam 111 and the movable beam that are directly opposite each other, or on the sides of the movable beam and the second side beam 112 that are directly opposite each other.
