Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0034] This utility model provides a medium-low speed maglev turnout adapted to slopes, with reference to... Figures 1-7, comprising:

[0035] a turnout base 1 as a supporting base of the whole turnout structure;

[0036] a fixed stack beam 2 and a movable stack beam 3, both of which include a base fitting surface 21 close to the turnout base 1 and an F-rail fitting surface 22 on the side away from the base fitting surface 21, and an angle a is processed between the F-rail fitting surface 22 and the base fitting surface 21;

[0037] a second driven beam 4, a first driven beam 5 and a driving beam 6, all of which are supported by a trolley 7 and have an angle a between them and the trolley 7;

[0038] a hinge shaft connecting rod 8, one end of which is installed on the turnout base 1 and the other end of which is fixedly installed on the trolley 7;

[0039] a locking device 9, which is arranged between the driving beam 6 and the turnout base 1 and is used for locking the turnout structure; and

[0040] a driving device 10, which is arranged between the driving beam 6 and the turnout base 1 and is used for driving the conversion of the turnout structure.

[0041] In this embodiment, the turnout foundation 1 serves as the core support part of the entire turnout structure, ensuring stability and load-bearing capacity in a slope environment; the fixed stack beam 2 and the movable stack beam 3 respectively bear the role of supporting the track and guiding the track conversion, and their foundation abutting surfaces 21 are adjacent to the turnout foundation 1, while the F rail mounting surfaces 22 away from the foundation are inclinedly arranged, forming a specific included angle a, wherein the included angle a is consistent with the included angle a between the turnout induction plate surface 11 and the horizontal position of the foundation surface, so as to adapt to the natural trend of the slope and ensure the safe and stable running of the maglev train on the slope. The second driven beam 4, the first driven beam 5 and the driving beam 6 are supported by the trolley 7, and the three constitute the main frame of the turnout, and through precise adjustment of the angle a, smooth and efficient track conversion can be realized even in a slope environment. The hinge shaft connecting rod 8 is connected to the turnout foundation 1 and the trolley 7 at both ends, and through its unique rotating mechanism, it ensures that the turnout structure remains balanced during the conversion process and adapts to the geometric changes of the slope. The locking device 9 and the driving device 10 are arranged between the driving beam 6 and the turnout foundation 1, and jointly participate in the dynamic conversion and locking process of the turnout structure. The locking device 9 ensures the safe fixation of the turnout after conversion, and the driving device 10 is the power source for realizing the motorization of the turnout. The design of the turnout structure of the present application fully considers the magnetic interaction between the maglev train and the track, as well as the influence of the slope terrain on the static and dynamic characteristics of the turnout, striving to maximize the operating efficiency while ensuring safety. It greatly broadens the application range of the maglev transportation system in urban construction, especially in areas with complex geographical conditions and variable terrain. Compared with the traditional turnout, the advantages of the present application are: seamless integration of the maglev turnout on the slope terrain is realized, the flexibility and accessibility of the maglev transportation network are enhanced; the friction loss in the turnout conversion process is reduced, the maintenance cost is reduced, and the economy of the system is increased; the accuracy and safety of the turnout conversion are improved, ensuring that the maglev train can also have the same or even higher running quality on the slope as the horizontal turnout.

[0042] Referring to Figures 1-4 , the included angle a of the F rail mounting surface 22 and the foundation abutting surface 21 on the fixed stack beam 2 and the movable stack beam 3 is directly machined by a machine tool. Among them, the use of a precision machine tool can ensure the consistency and accuracy of the angle, and thus ensure the stability and safety of the maglev train running on the slope. This process requires strict quality inspection standards to ensure that each part meets the design specifications and avoids potential safety hazards caused by manufacturing deviations.

[0043] Referring to Figure 5, the installation process of the hinge shaft connecting rod 8 involves a hard connection method that requires considering the possible angle between the hinge shaft connecting rod 8 and the installation surface on the trolley 7 during installation. Due to the possibility of incomplete fitting of the installation surface, special attention needs to be paid in actual operation. In order to ensure the smooth installation and flexibility of the hinge shaft connecting rod 8, a joint ball bearing 82 is usually installed through the rotating shaft 81. The purpose of this design is to add an additional degree of freedom to the hinge shaft connecting rod 8, making it more flexible in the vertical direction for adjustment and movement. In this way, even in the face of incomplete fitting of the installation surface, the hinge shaft connecting rod 8 can maintain good working condition, ensuring the stability and reliability of the entire system. In this way, the hinge shaft connecting rod 8 can move more flexibly in the vertical plane, thereby improving the flexibility and adaptability of the overall structure. The presence of the joint ball bearing 82 makes the hinge shaft connecting rod 8 move more smoothly in the vertical direction, reducing friction and resistance, and ensuring efficient operation of the mechanical system.

[0044] With reference to Figures 6-7 , the trolley 7 is placed with an angle a adjustment pad 61 between the second driven beam 4, the first driven beam 5 and the driving beam 6, which is a small component used to fine-tune the relative position of each component during actual assembly. These pads can compensate for the cumulative tolerance of different parts during manufacturing and assembly, ensuring that each track can be accurately laid according to the expected path, eliminating the gap caused by incomplete manufacturing precision.

[0045] With reference to Figures 1-2 , specifically, the driving mechanism includes a motor arranged in the up-down direction, optimizing the power transmission path, making energy conversion more efficient, and also facilitating maintenance and repair.

[0046] Specifically, with reference to Figure 2 , the locking device 9 includes a fixed shaft, a plurality of vertically movable locking shafts, and a locking slot opened at the lower end of the locking shaft, and the locking slot is adapted to the fixed shaft. The design of the locking device 9 ensures that when the maglev train passes through the turnout, the locking shaft can be accurately inserted into the locking slot, thereby achieving precise control of the train running direction. The fixed shaft as the main body of the locking device 9 is crucial to the performance of the entire device. The plurality of vertically movable locking shafts provide flexible adjustment capability to adapt to different trains and different operating conditions. The adaptability design of the locking slot and the fixed shaft not only ensures the reliability of the locking device 9, but also simplifies the maintenance and replacement process.

[0047] With reference to Figure 2The locking shaft in the locking device 9 can be vertically lifted by the electromagnetic drive device 10 to realize the functions of quick locking and releasing. Combined with the electromagnetic drive locking device 9, quick response can be realized to ensure that the turnout structure is quickly locked after the conversion is completed, thereby improving the overall automation degree and safety. The precise fitting of the vertically moving locking shaft and the fixed shaft forms a stable mechanical interlocking, thereby enhancing the stability of the turnout after conversion.

[0048] The fixed beam 2 and the movable beam 3 are made of high-strength lightweight alloy materials, which not only reduces the overall weight but also improves the structural strength, thereby reducing the load pressure of the turnout foundation 1 and helping to prolong the overall service life. In addition, the addition of the damping and buffering layer further improves the anti-seismic performance of the turnout structure, effectively resisting vibration and impact during the conversion process, protecting the internal components of the turnout from damage, and improving the smoothness of the overall operation.

[0049] The bottom of the trolley 7 is specially designed with a damping and buffering layer, which mainly functions to absorb and alleviate the vibration and impact force generated by the turnout structure during the conversion process. In this way, the damping and buffering layer effectively protects the turnout components from damage caused by vibration and impact, thereby ensuring the stability and reliability of the turnout system.

[0050] The turnout foundation 1 is usually made of high-strength concrete or metal alloy, which are two high-quality materials. High-strength concrete is one of the ideal choices for the turnout foundation 1 due to its excellent compression resistance and durability. This concrete is specially formulated and processed to ensure its stability and durability under heavy loads and harsh environments. Metal alloy materials are also suitable for the manufacture of the turnout foundation 1 due to their high strength and good toughness. Scientific smelting and processing of metal alloys can provide sufficient strength and corrosion resistance to ensure the stability and safety of the turnout foundation 1 during long-term use. Whether high-strength concrete or metal alloy materials are chosen, the goal is to ensure the reliability and durability of the turnout foundation 1 in actual application, thereby ensuring the safety and efficiency of railway transportation.

[0051] The above is only the preferred embodiment of the present application, and does not limit the implementation and protection scope of the present application. For those skilled in the art, it should be realized that any equivalent replacement and obvious changes made according to the content of the present application should be included in the protection scope of the present application.
