Description

Technical Field

[0001] The utility model relates to the field of track monorail transportation, in particular to a magnetic levitation turnout, specifically an adjustable angle bisecting device. Background Art

[0002] Medium and low speed maglev rail transit has the advantages of low noise, low vibration, low radiation, low cost and strong climbing ability, and is a new direction for the development of urban rail transit. Medium and low speed maglev turnouts are important equipment for realizing the reversal of maglev lines. The angle bisector is located between the turnout beams and is a transition connection device for the beams. It has the function of bisecting the beam switching angle to ensure the stability of the vehicle when passing the turnout. The installation of the existing maglev line angle bisector is through the F short rail overlapped on the front and rear beam F rails, but the structure has wear at the F rail overlap after the time switch on the turnout and the vertical cannot be adjusted, which easily causes the vertical deviation of the magnetic levitation surface of the turnout system after the F rail is worn.

[0003] The existing technical solution for the angle bisector device is that the F short rail boss of the angle bisector device is overlapped and installed on the F rail recess on the front and rear beams. After the turnout has been switched for a long time, this mechanism will be worn at the F rail step overlap, causing the F short rail to sink and the magnetic pole surface to be out of tolerance, affecting the stability of the vehicle passing the turnout, and even causing "rail smashing". The turnout system can only be leveled by replacing the F short rail of the angle bisector device and the F rail of the adjacent beam, and the maintenance cost is high. Utility Model Content

[0006] Optionally, a supporting pad is provided between the beam body below the connecting frame and the self-lubricating wear-resistant pad.

[0007] Optionally, an adjustment pad is provided between the self-lubricating wear-resistant pad and the supporting pad.

[0016] By arranging an adjustment pad under the self-lubricating anti-friction pad, the height of the connecting frame can be adjusted, and then the height of the connecting rail can be adjusted, which is convenient for the installation of the connecting rail, so that the magnetic pole surface of the connecting rail can be kept in the same plane as the magnetic pole surface of the main rail, and the magnetic pole surface can be replaced with different thickness adjustment pads to avoid excessive tolerance after wear.

[0017] If the self-lubricating anti-friction pad is severely worn and replacing the adjustment pad cannot eliminate the excess tolerance of the magnetic pole surfaces of the main rail and the connecting rail, a new self-lubricating anti-friction pad can be replaced.

[0026] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] The present application embodiment discloses an adjustable angle bisection device.

[0029] Reference Figure 1An adjustable angle bisector device includes a connecting rail 1 and a main rail 2 arranged at both ends of the connecting rail 1. The two parallel connecting rails 1 are connected by a connecting frame 3, and a pull rod assembly 4 is arranged below the connecting frame 3; a lap protrusion is provided on the main rail 2, and a lap groove matching the lap protrusion is provided at both ends of the connecting rail 1. The main rail 2 is overlapped on the connecting rail 1 through the matching of the lap protrusion and the lap groove, so that the magnetic pole surfaces of the connecting rail 1 and the main rail 2 are flush. A lap protrusion is provided on the end of the main rail 2, and a lap groove matching the lap protrusion is provided at both ends of the connecting rail 1. In this way, the main rail 2 can overlap on the connecting rail 1 through the matching of the protrusion and the groove, ensuring a smooth transition connection between the connecting rail 1 and the main rail 2. When a vehicle passes through the angle bisector device, the structure of the device ensures a stable connection between the connecting rail 1 and the main rail 2. The pull rod assembly 4 of the connecting frame 3 can adjust the height of the connecting rail 1 as needed to ensure that the magnetic pole surfaces of the connecting rail 1 and the main rail 2 remain in the same plane. This design effectively bisects the angle and ensures the stability and accuracy of the connection.

[0030] Reference Figure 2 , a beam body is arranged below the connecting frame 3, a self-lubricating wear-resistant pad 7 is arranged on the beam body, and a wear-resistant plate 10 that slides with the self-lubricating wear-resistant pad 7 is arranged at the bottom of the connecting frame 3. The working principle of this design is based on the need to reduce friction and wear: the self-lubricating wear-resistant pad 7 is made of a material with high wear resistance and low friction coefficient. When the connecting frame 3 experiences various mechanical pressures and dynamic loads during operation, the wear-resistant pad can slide smoothly on the wear-resistant plate 10, thereby reducing direct metal-to-metal friction. This not only protects the structural integrity of the beam body and the connecting frame 3, but also ensures the stability and reliability of the device in long-term use. In addition, this self-lubricating and wear-resistant matching design allows the device to achieve a significant reduction in maintenance costs by simply adjusting or replacing the self-lubricating wear-resistant pad 7 when the original structural components are worn, rather than replacing the entire structural unit.

[0031] Self-lubricating wear-resistant pads 7 are pads made of special materials with self-lubricating and wear-resistant properties. They are usually used to reduce friction and wear between mechanical parts and improve the working efficiency and service life of equipment.

[0032] The end of the main rail 2 is provided with a protrusion, and the protrusion surface is provided with a bolt hole. The pressure plate 11 is fixed on the protrusion surface by bolts, and the lower surface of the pressure plate 11 is flush with the upper surface of the connecting rail 1 to prevent the connecting rail 1 from tilting. The two ends of the connecting rail 1 are designed with step surfaces, and these step surfaces are provided with overlapping grooves for accurately accommodating the overlapping protrusions on the main rail 2. In order to ensure that this overlap is firm and stable, a pressure plate 11 is fixed on the step surface by bolts, and the pressure plate 11 is specifically used to press the overlapping protrusions, thereby ensuring that the contact between the connecting rail 1 and the main rail 2 is tight and seamless. The upper surface of the pressure plate 11 is designed to be flush with the upper surface of the connecting rail 1. This design ensures that after the connecting rail 1 and the main rail 2 are connected, the overall magnetic pole surface is continuous and flat, without ups and downs, which is crucial for the smooth operation of the maglev train. This design working mode ensures the mechanical strength and long-term durability of the joint through mechanical fixation (bolts and pressure plate 11), and also allows for rapid disassembly and replacement when necessary.

[0033] The tie rod assembly 4 includes a first tie rod 41 and two second tie rods 42 respectively hinged at both ends of the first tie rod 41. A first mounting seat 43 is provided on the connecting frame 3, and a second mounting seat 44 is provided on the beam body below the main rail 2. The middle part of the first tie rod 41 is hinged to the first mounting seat 43, and the end of the second tie rod 42 away from the first tie rod 41 is hinged to the second mounting seat 44.

[0034] The tie rod assembly 4 consists of a central first tie rod 41 and two second tie rods 42 respectively hinged at both ends. The middle part of the first tie rod 41 is connected to the first mounting seat 43 on the connecting frame 3 by hinged means, and the end of each second tie rod 42 away from the first tie rod 41 is respectively hinged to the second mounting seat 44 on the beam body below the main rail 2. This design allows the tie rod assembly 4 to provide the necessary support force between the connecting frame 3 and the beam body, while allowing a certain degree of movement and adjustment to achieve the angle bisection function, and is used at the connection of the turnout beam to eliminate the corner impact when the two sections of the turnout beam pass the train, so that the train passes the turnout smoothly.

[0035] Two groups of tie rod assemblies 4 are symmetrically arranged along the central axis of the main rail 2. This symmetrical configuration not only increases the overall rigidity of the structure, but also plays an important role in maintaining the precise alignment between the connecting frame 3 and the beam body, ensuring the reliability and efficiency of the device in long-term operation. In the event of unbalanced loads or abnormal operating conditions that may occur, the symmetrical tie rod assemblies 4 can also provide additional protection and reduce potential damage risks, thereby extending the service life of the equipment and reducing maintenance costs.

[0036] The connecting rail 1 includes an inner leg, an outer leg, a web and a wing plate, wherein the web is located between the inner leg and the outer leg, and the wing plate is located on the inner side of the inner leg. Such a structural design effectively improves the structural strength and rigidity of the connecting rail 1. The inner leg and the outer leg form the main frame of the connecting rail 1, providing basic support and shape. The web plate, as the connecting part between the two legs, increases the lateral stability and torsional rigidity of the connecting rail 1, and helps to withstand and disperse the lateral and vertical pressures caused by the operation of the train. The arrangement of the wing plate on the inner side further enhances the lateral support of the structure, especially when the track is subjected to lateral forces (such as wind pressure or the dynamic effects of a train passing quickly), the wing plate can provide additional bending resistance and stability.

[0037] Reference Figure 3 , a support platform 5 is provided on the connecting frame 3, and the connecting rail is overlapped on the support platform 5 and fixed by bolts. The support platform 5 provides a solid support point for the wing plate, which not only increases the lateral and vertical load-bearing capacity of the entire connecting rail 1, but also ensures the stability and alignment accuracy of the connecting rail 1 when the train passes. Through the close overlap of the wing plate and the support platform 5 and the use of bolts to fix, this structural design effectively distributes the load and pressure evenly to the entire connecting frame 3, thereby reducing the pressure concentration at a single point and increasing the overall durability and fatigue resistance.

[0038] The support platform 5 includes a vertically connected support transverse plate and a support vertical plate, the support transverse plate is used to support the wing plate, and the bottom of the support vertical plate is used to install the wear-resistant plate 10. The support transverse plate is located at the top and is directly used to support the wing plate. Such a configuration not only increases the lateral stability of the entire device, but also ensures the uniform distribution of the wing plate when it bears lateral and vertical loads, thereby reducing the stress concentration caused by uneven loads.

[0039] Reference Figure 3 A rib plate 6 is provided between the supporting transverse plate and the supporting vertical plate. The rib plate 6 is a structural reinforcement element, connecting the transverse plate and the vertical plate, providing additional lateral and vertical support, and helping to resist and disperse the vibration and load caused by the operation of the train and other external forces. Such a structural layout effectively reduces possible bending and twisting, ensuring the overall strength and durability of the support platform 5.

[0040] Reference Figure 4A support pad 9 is provided between the beam body and the self-lubricating wear-resistant pad 7 below the connecting frame. As a structural intermediate layer, the support pad 9 helps to evenly distribute the pressure transmitted from the connecting frame 3, thereby avoiding excessive stress concentration at specific points, which helps to extend the service life of the self-lubricating wear-resistant pad 7 and the beam body below. In addition, the support pad 9 also provides an adjustable interface. By replacing pads of different thicknesses, the distance from the beam body to the bottom of the connecting frame 3 can be finely adjusted to further optimize the alignment of the pole faces and the stability of the overall structure. Regarding the fixing method of the support pad 9, the optional methods include bolting, welding, or fixing with a specific clamping device. Bolting is a common and reliable method that allows the pad to be easily removed and replaced when necessary, while welding provides a more solid fixation, but is not convenient for later replacement of the pad.

[0041] An adjustment pad 8 is provided between the self-lubricating wear-resistant pad 7 and the support pad 9. In the design in which the support pad 9 is provided between the beam body below the connecting frame and the self-lubricating wear-resistant pad 7, an adjustment pad 8 is further configured between the self-lubricating wear-resistant pad 7 and the support pad 9. The function of this design is to provide additional adjustment capabilities to ensure the precise alignment of the height of the connecting frame 3 and the corresponding magnetic pole surface. The adjustment pad 8 enables the system to restore the original height and alignment state of the equipment by replacing or adjusting the thickness of the adjustment pad 8 during long-term use, even if the structural components are worn or the size changes due to external environmental factors. This not only improves the maintainability and adaptability of the overall device, but also ensures the stability and efficiency of the equipment operation.
