Description

Technical Field

[0001] This utility model belongs to the technical field of maglev rail transit, specifically, it relates to a sliding support and guiding device for a turnout in an embedded maglev transportation system. Background Technology

[0002] Compared to conventional rail transit systems, maglev transportation systems offer advantages such as smaller turning radius, lower operating noise, stronger climbing ability, lower operation and maintenance costs, and greater safety and reliability. Furthermore, maglev systems are unaffected by adverse weather conditions, enabling 24 / 7 operation. Maglev systems utilize magnetic forces to achieve contactless levitation, guidance, and traction between the train and the track. Therefore, maglev transportation systems have gradually become an important form of modern urban rail transit.

[0003] Due to its inherent characteristics, the medium- and low-speed maglev transportation system will play an important role in the future development of urban rail transit. In particular, it may become an important option for cities where geological conditions make it difficult to build subways. It will inevitably become a widely used rail public transportation tool for urban, suburban, short-distance intercity, and tourist area transportation connections, and has extremely broad market prospects.

[0004] The turnouts of the embedded maglev transportation system are also different from those of other wheel-rail transportation systems. They use multiple short straight units to fit turnout curves with various radii of curvature. At the same time, in order to meet the requirements of standardized design of the embedded maglev transportation system, the length of the turnout is the same as or twice the length of the track beam.

[0005] In embedded medium-low speed maglev transportation systems, the sliding support and guiding device of the turnout serves as the main structure for supporting, sliding, and controlling the accuracy of the turnout's trajectory, playing a crucial role in the turnout's operation. Due to the limited space between the turnout beam and the turnout plate, the structural design must simultaneously meet the requirements of installation within a limited space and convenient maintenance in the future.

[0040] Example 1

[0041] In this embodiment, a sliding support and guiding device for an embedded maglev transportation system turnout is specifically provided. The sliding support and guiding device is arranged between the turnout beam 4 and the turnout plate 6. Generally, multiple sliding supports and guiding devices are arranged. As the main structure that provides support, sliding and controls the motion trajectory accuracy of the turnout beam 4, the sliding support and guiding device plays an important role in the operation of the turnout.

[0042] In this embodiment, the sliding support and guiding device mainly includes: a connecting bracket 7, a sliding support unit 1, and a guiding unit 2, as specifically designed as follows:

[0043] ① A connecting bracket 7 is installed on the turnout beam 4. The connecting bracket 7 serves as a bearing base for the sliding support and guide device. The connecting bracket 7 and the turnout beam 4 are connected and locked together by connecting bolts 3. During actual installation, to improve the positioning accuracy of the connecting bracket 7, a locking tenon 7.1 is provided on the connecting bracket 7. The locking tenon 7.1 is installed in the positioning groove of the turnout beam 4 to pre-position the connecting bracket 7. Preferably, the locking tenon 7.1 and the connecting bracket 7 can be fixed by screws or by snap-fit ​​assembly; no limitation is made here.

[0044] ② A sliding support unit 1 and a guide unit 2 are installed on the same connecting bracket 7. The sliding support unit 1 and the guide unit 2 work together on the guide rail 5 of the turnout plate 6. The sliding support unit 1 provides sliding support for the movement of the track beam, and the guide unit 2 provides guidance for the movement of the track beam.

[0045] In practical applications, the specific design is as follows:

[0046] The sliding support unit 1 includes a spherical support 1.1 and a sliding support plate 1.3. The spherical support 1.1 is mounted on the connecting bracket 7, and the sliding support plate 1.3 is mounted on the spherical support 1.1. The sliding support plate 1.3 slides in contact with the rail surface of the guide rail 5. The sliding support plate 1.3 is made of a self-lubricating and wear-resistant material to ensure that it can slide on the guide rail 5 while providing sufficient support for the turnout beam 4. During operation, because the spherical support 1.1 has a certain degree of flexibility, when encountering unevenness on the rail surface of the guide rail 5, the support surface of the sliding support plate 1.3 can still maintain close contact with the rail surface of the guide rail 5, effectively controlling stress concentration and structural stability. The spherical support 1.1 acts as a movable joint. In this embodiment, the spherical support 1.1 has the following structure: a spherical support head and a spherical support seat. One end of the spherical support head is mounted on the connecting bracket 7, and the other end is assembled and connected to the spherical support seat through a spherical fit. The other end of the spherical support seat is equipped with a sliding support plate 1.3, so that when the sliding support plate 1.3 slides in contact with the rail surface, it has mobility under the action of the spherical support 1.1, so as to better contact the rail surface of the guide rail 5.

[0047] The end connection between the sliding support plate 1.3 and the spherical support 1.1 is as follows: a groove is provided at the end of the spherical support 1.1, and the sliding support plate 1.3 is clamped in the groove. In order to ensure that the sliding support plate 1.3 can effectively contact the guide rail 5 at different heights, an adjustment shim 1.2 is provided between the ends of the sliding support plate 1.3 and the spherical support 1.1. The installation position of the end of the sliding support plate 1.3 relative to the spherical support 1.1 is adjusted by the adjustment shim 1.2 to ensure that the sliding support plate 1.3 can slide in contact with the guide rail 5.

[0048] The guide unit 2 includes a guide wheel shaft 2.1 and a guide wheel 2.2. The guide wheel shaft 2.1 is mounted on the connecting bracket 7 and the guide wheel 2.2 is rotatably mounted on the guide wheel shaft 2.1. The guide wheel 2.2 rolls in contact with the side of the guide rail 5 so as to guide the operation of the turnout beam 4 through the rolling motion of the guide wheel 2.2 on the side of the guide rail 5.

[0049] To facilitate future maintenance, the sliding support and guide device further includes a side block 7.2, which is mounted on the connecting bracket 7 and locked to the connecting bracket 7 by connecting bolts 3. The side block 7.2 and the guide unit 2 are respectively arranged on both sides of the guide rail 5. The vertical extension surface of the side block 7.2 on the surface of the connecting bracket 7 can at least cover the sliding support plate 1.3, so as to provide good protection for the sliding support plate 1.3.

[0050] The sliding support and guide device provided in this embodiment are installed on the same connecting bracket 7, which can effectively reduce the space used and make the structure more compact. Compared with the prior art, which designs the sliding support unit and the guide unit separately, the technical solution adopted in the above embodiment installs the sliding support unit and the guide unit on the same connecting bracket 7. At the same time, the installation arrangement of the sliding support unit and the guide unit is reasonably designed, which can make the overall structure more compact to a large extent, thus effectively reducing the space used. Moreover, since it is installed on the turnout beam by the connecting bracket, the sliding support unit and the guide unit can be installed simultaneously in one go, making the whole installation process simpler and more convenient.

[0051] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
