Abstract
Description
Technical Field
[0001] The present invention relates to the field of magnetic levitation transportation, and in particular to a segmental magnetic levitation turnout. Background Art
[0002] Currently, conventional high-speed maglev systems primarily utilize integrally elastic lateral bending turnouts, including continuous steel beams. During switching, the elastic deformation of the beam itself is utilized to achieve line switching. This method utilizes the beam itself to bend to form the desired siding line shape. However, this operating method presents the following technical issues: First, excessive structural stress: During the elastic bending of the beam, significant stress is generated within the beam. For example, in one existing design, with a turnout length of approximately 78.432 meters and a siding curve radius of 658 meters, the theoretical stress generated within the beam due to bending reaches approximately 150 MPa. This high stress condition can easily lead to structural fatigue damage in long-term service. Second, the turning radius is excessively large. To maintain technically feasible and economically reasonable control over deformation stress, existing turnout designs must employ a relatively large turning radius. This results in a long turnout length, excessive installation space, and low space utilization efficiency.

Any modification of the structure, change in the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.
[0078] like Figure 5 As shown, the present application provides a segmented maglev turnout 1, comprising a plurality of first segment turnout beam sections 10 connected in sequence and a plurality of second segment turnout beam sections 20 connected in sequence, wherein Figure 5 The four sections on the left are the first section turnout beam section 10, and the four sections on the right are the second section turnout beam section 20. Figure 1 As shown, the first section turnout beam section 10 includes a first beam section body 110, a first load-bearing end 113 and a first mounting end 114. The first load-bearing end 113 is used to carry a maglev train. The first mounting end 114 and the first load-bearing end 113 are respectively located at the two ends of the height direction of the first beam section body 110. The first load-bearing end 113 is defined as a side of the first section turnout beam section 10 used to carry a maglev train, which is the upper end of the first section turnout beam section 10 in this application. The first mounting end 114 is the lower end of the first section turnout beam section 10, which is used to install other equipment.
[0079] like Figure 8 As shown, the second-segment turnout beam segment 20 includes a second beam segment body 210, a second load-bearing end 250, and a second mounting end 260. The second load-bearing end 250 is used to support the maglev train, and the second mounting end 260 and the second load-bearing end 250 are respectively located at the two ends in the height direction of the second beam segment body 210. In this application, the second mounting end 260 is the upper end of the second-segment turnout beam segment 20, and the second mounting end 260 is the lower end of the second-segment turnout beam segment 20, which is used to mount other equipment.
[0080] like Figure 13As shown, the first driving mechanism connected to the first segment switch beam section 10 includes a first driving motor 140, a transmission screw 141 and an output screw sleeve 142. The transmission screw 141 is movably connected to the output end of the first driving motor 140, and the output screw sleeve 142 is connected to the transmission screw 141 through a threaded pair. The output screw sleeve 142 is connected to the mounting end 114 of the beam section body 110. When it is necessary to drive the segmented maglev switch 1 to switch, the transmission screw 141 is driven to rotate by the first driving motor 140. While rotating, the conventional screw drives the output screw sleeve 142 to move along the axial direction of the transmission screw 141, and at the same time drives the segment switch beam section 10 connected to the output screw sleeve 142 to move, thereby achieving switching.
[0081] like Figure 14 and Figure 15 As shown, the second driving mechanism connected to the second section turnout beam segment 20 includes a second driving motor 270 , a transmission rod 271 , a transmission wheel 272 and a movable slide rail 273 .
[0082] The two ends of the transmission rod 271 are respectively connected to the output end of the second drive motor 270 and the transmission wheel 272. The second drive motor 270 drives the transmission wheel 272 to rotate in a plane parallel to the surface of the mounting base plate 30 via the transmission rod 271. The movable rail 273 is fixedly mounted to the mounting end 114 of the beam body 110. The movable rail 273 comprises two parallel rails, the spacing between which matches the outer diameter of the transmission wheel 272. The transmission wheel 272 is embedded in the movable rail 273. When the segmental maglev turnout 1 needs to switch, upon receiving the switch command, the second drive motor 270 begins operation, driving the transmission wheel 272 to rotate in a plane parallel to the surface of the mounting base plate 30 via the transmission rod 271. Through the cooperative relationship between the transmission wheel 272 and the movable rail 273, the movable rail 273 is fixedly connected to the segmental turnout beam segment 10, converting the in-plane movement of the transmission wheel 272 into the in-plane movement of each segmental turnout beam segment 10, thereby achieving the switch.
[0083] In this embodiment, a second drive motor 270 is used to drive a drive wheel 272 for in-plane rotation. The second drive motor 270 is positioned midway between the switching displacements of the segmental turnout beam segment 10. The length of the drive rod 271 only needs to be half the displacement of the segmental turnout beam segment 10 during switching. For segmental turnout beam segments 10 requiring large switching displacements, the drive mechanism of this embodiment can shorten the length of the drive rod 271, reducing the overall size of the drive mechanism.
[0084] The electrical control system is electrically connected to the first drive mechanism and the second drive mechanism, and the electrical control system drives the first drive mechanism and the second drive mechanism. Figure 6 The first section turnout beam section 10 and the second section turnout beam section 20 of each straight section are switched to form a switch as shown in FIG. Figure 7 The curved track shown.
[0085] The mounting base 30 is directly or indirectly connected to the first section turnout beam segment 10 or the second section turnout beam segment 20 for supporting the first section turnout beam segment 10 or the second section turnout beam segment 20. The mounting base 30 can be the deck of an elevated bridge or the ground, which is not limited here.
[0086] like Figure 1 As shown, the first section turnout beam segment 10 includes a first beam segment body 110, a first connecting structure 111 and a second connecting structure 112. Figure 1 It shows a situation where two first-segment turnout beam segments 10 are connected to each other via a first connecting structure 111 and a second connecting structure 112 .
[0087] The first beam segment body 110 includes a first load-bearing end 113 and a first mounting end 114, wherein the first load-bearing end 113 is used to carry a maglev train (not shown in the figure). When the first section turnout beam segment 10 is mounted on the mounting base plate 30, as shown in FIG. Figure 2 As shown in the cross-sectional view, the first mounting end 114 and the first bearing end 113 are respectively arranged at both ends of the height direction of the first beam segment body 110, wherein the first bearing end 113 is installed upward for bearing the maglev train, as shown in FIG. Figure 12 As shown, the first mounting end 114 is mounted downward to connect to the bottom mounting substrate 30 .
[0088] The first connection structure 111 and the second connection structure 112 of each first-segment turnout beam segment 10 can be interconnected. The first connection structure 111 and the second connection structure 112 are respectively arranged at both ends of the length direction of the first beam segment body 110. The first-segment turnout beam segments 10 can be arranged sequentially along the length direction in the same direction. The second connection structure 112 of the preceding first-segment turnout beam segment 10 is connected to the first connection structure 111 of the subsequent first-segment turnout beam segment 10, thereby achieving interconnection between the segment turnout beam segments 10.
[0089] Figure 3 Schematic diagram of the structure of the first connecting structure 111 at one end of the first section turnout beam 10. In this embodiment, the first connecting structure 111 includes a chute provided along the length direction of the first beam body 110, and the axis of the chute extends along the axis direction of the first section turnout beam 10. Figure 4 This is a structural schematic diagram of the second connecting structure 112 at the other end of the first segment turnout beam section 10. The second connecting structure 112 is a first connecting pin 115 protruding from the first beam section body 110 along the axial direction of the segment turnout beam section 10, and the axis of the first connecting pin 115 is along the vertical direction. The first connecting pin 115 of the second connecting structure 112 matches the width of the slide groove of the first connecting structure 111.
[0090] When two adjacent first-segment turnout beam segments 10 are connected to each other, the first connecting pin 115 of the second connecting structure 112 on the first first-segment turnout beam segment 10 is inserted into the chute of the first connecting structure 111 on the second first-segment turnout beam segment 10. The first connecting pin 115 can rotate relative to the chute while also moving along the axial direction of the chute. This arrangement allows the two adjacent first-segment turnout beam segments 10 to have the freedom to rotate relative to each other around a vertical axis and the freedom to move along the axial direction. When multiple first-segment turnout beam segments 10 are connected to each other, they can move together to achieve turnout switching.
[0091] like Figure 8 The second segment turnout beam section 20 is connected by the third connecting structure 220 and the fourth connecting structure 230. Figure 9 As shown, the third connecting structure 220 includes a first connecting lug with a first pin hole 221 defined therein. The first pin hole 221 is spaced apart from one end surface of the second segment turnout beam section 20. To further ensure that the second connecting pin 240 can be securely mounted on the first connecting lug, the third connecting structure 220 includes two first connecting lugs, each of which is provided with two first pin holes 221.
[0092] like Figure 10 As shown, in this embodiment, the fourth connecting structure 230 includes a second connecting lug and a second connecting pin 240. The second connecting lug is provided with a second pin hole 231. The second pin hole 231 is spaced apart from the other end surface of the second segment turnout beam 20. To further ensure that the second connecting pin 240 can be securely mounted on the second connecting lug, the second connecting structure 112 includes two second connecting lugs, each of which is provided with two second pin holes 231. The first pin hole 221 and the second pin hole 231 respectively mate with the second connecting pin 240.
[0093] Figure 11 This is a schematic diagram of the structure of the first pin hole 221 on the first connecting lug and the second pin hole 231 on the second connecting lug in this embodiment, connected by a second connecting pin 240. The second connecting pin 240 passes through the first pin hole 221 and the second pin hole 231, respectively, from top to bottom. The interconnection of the first pin hole 221, the second pin hole 231, and the second connecting pin 240 on the first and second connecting lugs not only achieves axial connection between adjacent second-segment turnout beam segments 20, but also preserves the freedom of rotation between the two. When the segmented maglev turnout 1 switches, the drive mechanism drives each segmented turnout beam segment 10 to move, achieving linear changes in the segmented maglev turnout 1.
[0094] like Figure 5 As shown, the segmental maglev turnout 1 is composed of a plurality of first segment turnout beam segments 10 and second segment turnout beam segments 20, wherein Figure 5 The four turnouts on the left are first-segment turnout beam sections 10, and the four on the right are second-segment turnout beam sections 20. The multiple first-segment turnout beam sections 10 are connected to each other through the first connecting structure 111 and the second connecting structure 112. The second-segment turnout beam sections 20 are connected to each other through the third connecting structure 220 and the fourth connecting structure 230. Figure 6 As shown in FIG, the segmental maglev switch 1 is in a straight line state. Figure 7 The figure shows a segmented maglev turnout 1 in a curved state after switching. Because the first-segment turnout beam segments 10 of the segmented maglev turnout 1 are connected by first and second connecting structures 111 and 112, and the second-segment turnout beam segments 20 are connected by third and fourth connecting structures 220 and 230, they have a certain degree of freedom of movement. When switching is required, the first and second turnout beam segments 10, 20 are driven to move. Since each first-segment switch beam segment 10 and the second-segment switch beam segment 20 are movably connected, the position changes before and after the switch, and the first-segment switch beam segment 10 and the second-segment switch beam segment 20 themselves will not be deformed. There is no bending stress on each first-segment switch beam segment 10 and the second-segment switch beam segment 20 due to the switch, which avoids the first-segment switch beam segment 10 and the second-segment switch beam segment 20 being in a high stress state due to the switch action, thereby extending the service life of the segmented maglev switch 1.
[0095] like Figure 6 and Figure 7 As shown, the segmental maglev turnout 1 in this application is composed of 8 turnout beams. Figure 6 The segmental maglev turnout 1 is in a straight line state. Figure 7 The first segment of the maglev turnout 1, which is in a curved state after switching, uses a first drive mechanism consisting of a first drive motor 140, a drive screw 141, and an output screw sleeve 142. This simplifies the structure of the drive mechanism and improves drive reliability. The second segment of the turnout 20, which is in a curved state after switching, uses a second drive mechanism consisting of a second drive motor 270, a drive rod 271, a drive wheel 272, and a movable slide rail 273. The drive rod 271 is the shortest possible, requiring only half the displacement during switching to achieve drive. Using a shorter drive rod 271 allows for long-distance displacement, reducing the space occupied by the drive mechanism.
[0096] like Figure 12As shown, the segmented maglev turnout 1 further includes a first locking mechanism 120 and a second locking mechanism 130 for locking with an external fixing mechanism. The first locking mechanism 120 and the second locking mechanism 130 are respectively disposed on both sides of the mounting end 114 along the width direction of the first beam segment body 110. Here, the first locking mechanism 120 and the second locking mechanism 130 on both sides of the first beam segment body 110 are used as an example for illustration. In practice, the first locking mechanism 120 and the second locking mechanism 130 are also respectively disposed on both sides of the second beam segment body 210. Among them, multiple first locking mechanisms 120 are installed on the mounting base plate 30 along one side of the segmented maglev turnout 1, and the number of the first locking mechanisms 120 matches the number of the first segment turnout beam section 10 and the second segment turnout beam section 20, that is, the first locking mechanisms 120 correspond one-to-one with the first segment turnout beam section 10 and the second segment turnout beam section 20 to achieve reliable locking of the first segment turnout beam section 10 and the second segment turnout beam section 20. Even if one of the first locking mechanisms 120 fails, it will not affect the locking effect of the entire segmented maglev turnout 1. When the segmented maglev turnout 1 is in a state such as Figure 6 In the straight type shown, each first locking mechanism 120 is locked with the corresponding first segment switch beam section 10 or second segment switch beam section 20, ensuring that there will be no accidental movement when the train passes through the segmented maglev switch 1, ensuring the safe passage of the train.
[0097] Continue as Figure 6 and Figure 7 As shown, the second locking mechanism 130 is installed on the mounting base plate 30 and opposite to the first locking mechanism 120 on both sides of the segmented maglev switch 1. The number of the second locking mechanisms 130 matches the number of the first segment switch beam sections 10 and the second segment switch beam sections 20, that is, the second locking mechanisms 130 correspond to the first segment switch beam sections 10 and the second segment switch beam sections 20 one by one, so as to achieve reliable locking of the segmented maglev switch 1. Even if one of the second locking mechanisms 130 fails, it will not affect the locking effect of the entire segmented maglev switch 1. When the segmented maglev switch 1 is in a state as shown in FIG. Figure 7 In the curved shape shown, each second locking mechanism 130 is locked with the corresponding first segment switch beam section 10 or second segment switch beam section 20, ensuring that there will be no accidental movement when the train passes through the segmented maglev switch 1, ensuring the safe passage of the train.
[0098] In this embodiment, the first locking mechanism 120 and the second locking mechanism 130 both use electromagnetic locking devices. The first locking mechanism 120 and the second locking mechanism 130 have the same structure, both including an electro-permanent magnetic chuck, a locking bracket and a travel switch, wherein the electro-permanent magnetic chuck and the travel switch are fixedly mounted on the locking bracket. Figure 12As shown, the second locking mechanism 130 locks and positions the segment switch beam section 10 by sucking the crossbeam 118 at the bottom of the first beam section body 110 with an electric permanent magnetic suction cup. When the crossbeam 118 and the electric permanent magnetic suction cup of the second locking mechanism 130 are sucked tightly, the position of the crossbeam 118 body 110 is locked and will not move along the Figure 12 Movement occurs in the left and right directions shown.
[0099] In this embodiment, the electro-permanent magnetic locking device is installed on the side of the crossbeam 118. In other embodiments, the electro-permanent magnetic locking device can also be installed below the crossbeam 118 or in front of the crossbeam 118 along the axial direction of the first beam segment body 110 (here, only the crossbeam 118 at the bottom of the first beam segment body 110 is used as an example; the same crossbeam 118 is also located at the bottom of the second beam segment body 210). Using an electromagnetic locking device, the electro-permanent magnetic suction cup locks the first section switch beam segment 10 and the second section switch beam segment 20 through the crossbeam 118. No mechanical wear is generated during the locking process, and the locking is reliable, thereby extending the service life of the first locking mechanism 120 and the second locking mechanism 130.
[0100] The segment turnout beam section 10 further includes a running mechanism and a driving mechanism. The running mechanism is arranged at the first mounting end 114 or the second mounting end 260. The first driving mechanism is connected to the first mounting end 114, and the second driving mechanism is connected to the second mounting end 260. Figure 12 As shown, the running mechanism includes a roller 150 installed at the bottom of the beam 118. When the first drive mechanism and the second drive mechanism drive the segmented magnetic levitation switch 1 to switch, the roller 150 moves on the surface of the mounting base plate 30, thereby reducing the friction resistance during relative movement between the segmented switch beam section 10 and the mounting base plate 30.
[0101] Continue as Figure 1 As shown, the segmented maglev turnout 1 also includes a displacement limiting mechanism. This mechanism includes a connecting rod 160, which includes a first connecting end 161 and a second connecting end 162. The first connecting end 161 is movably connected to the first mounting end 114 of the first beam segment body 110, and the second connecting end 162 is used to securely connect to an external portion (e.g., the surface of the mounting base 30) to limit the first connecting end 161 from rotating about the second connecting end. The connecting rod 160 at the bottom of the first beam segment body 110 is used as an example here; a similar connecting rod 160 is also present at the bottom of the second beam segment body 210.
[0102] Specifically, in this embodiment, the second connection end 162 of the connecting rod 160 is fixedly connected to the surface of the mounting base 30. When the first driving mechanism drives the first segment turnout beam segment 10 to move, the displacement limiting mechanism can limit the movement range of the first segment turnout beam segment 10. The end of the first segment turnout beam segment 10 connected to the first connection end 161 can only move around the second connection end 162 with the connecting rod 160 as the radius, thereby limiting the displacement of the segment turnout beam segment 10, preventing the first segment turnout beam segment 10 from moving beyond the expected position, and ensuring the movement safety of the segment turnout beam segment 10 during the switching process. Each displacement limiting mechanism is respectively provided in a one-to-one correspondence with the first segment turnout beam segment 10 or the second segment turnout beam segment 20, so as to have a good limiting effect on each first segment turnout beam segment 10 or the second segment turnout beam segment 20.
[0103] like Figure 12 As shown, the first load-bearing end 113 includes a T-shaped cross-section beam, and the maglev train rides on the T-shaped cross-section beam during operation. Figure 16 As shown, the first load-bearing end 113 can also be a U-shaped cross-section beam. During operation, the maglev train's suspension module runs within the groove of the U-shaped cross-section beam. In this application, the load-bearing end of the segmental maglev turnout 1, whether a T-shaped cross-section beam or a U-shaped cross-section beam, can be driven by a drive mechanism to achieve displacement and switching. The shape of the load-bearing end does not limit the use of the various structures of the segmental turnout beam segment 10 of this application.
[0104] The segmented maglev turnout 1 of this application utilizes multiple sequentially connected first-segment turnout beams 10 and multiple sequentially connected second-segment turnout beams 20. The turnout sidings utilize circular curves, shortening the turnout length by over 10 meters compared to existing turnouts. The turnout sidings are linearly fitted with straight line segments. The first-segment turnout beams 10 and the second-segment turnout beams 20 are connected by an articulated joint. These first-segment turnout beams 10 and 20 can be constructed of steel beams, more economical concrete, or other materials suitable for superconducting maglev transportation. The drive mechanism employed in this application is simple in structure, reducing the overall height of the segmented turnout beams 10 and improving turnout stability. The present application adopts a driving mechanism including a push rod mechanism or a rocker mechanism to shorten the working time of the switch and improve work efficiency; the locking mechanism adopts an electromagnetic mechanism, which is wear-free when locked. An installation base plate 30 is set under the segment switch beam section 10 to facilitate inspection and maintenance. In an emergency, passengers on the maglev train can also be evacuated through the installation base plate 30.
