Description
Technical Field
[0001] This utility model relates to the field of air rail technology, specifically to a bogie structure and air rail system suitable for harsh environments. Background Technology
[0002] Aerial rail transport systems (such as monorails and suspended track systems) face a series of challenges when operating in severe weather conditions such as sandstorms, rain, and snow: 1. Sandstorm erosion and wear: In sandstorms, sand particles cause severe erosion and wear on the tracks and other components of the aerial rail transport system, shortening the service life of the equipment. Sandstorms can also clog critical components such as air filters and radiators, affecting normal vehicle operation. In addition, strong winds can cause vehicles to tilt, affecting their stability. 2. Reduced visibility: Sandstorms significantly reduce visibility, greatly hindering the driver's vision and increasing operational safety risks. Drivers may have difficulty accurately judging the track ahead and the surrounding environment, easily leading to collisions or derailments. 3. Slippery and icy tracks: Rain and snow make the tracks slippery, increasing the braking distance of the train and the risk of derailment. Therefore, it is necessary to design a bogie structure and aerial rail system that can adapt to harsh environments. Utility Model Content

[0039] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0040] like Figure 1 As shown, this utility model provides a bogie structure suitable for harsh environments, including a bogie, the lower end of which is hinged to the car body 5. A roll stop is provided on the bogie to limit and buffer the roll angle of the car body 5. A motor frame 3 is provided above the bogie, and the motor frame 3 is vertically movably connected to the bogie. Figure 3 As shown, an elastic vertical stop 4 is provided between the bogie and the motor frame 3. The force exerted by the car body 5 on the roll stop is transmitted to the motor frame 3 through the vertical stop 4. Positioning wheels 31 are provided at both ends of the motor frame 3. The positioning wheels 31 are used to abut against the track beam 6 and transmit the force on the motor frame 3 to the track beam 6. Multiple lugs are provided on the edge of the motor frame 3. A connecting rod is fixedly installed at the upper end of the bogie. The upper end of the connecting rod passes through the lugs and is fixed with bolts. The bolts can be welded to the connecting rod. The motor frame 3 can move axially along the connecting rod. The vertical stop 4 is a spring. Under the action of the vertical stop 4, the positioning wheels 31 on the motor frame 3 abut against the top of the track beam 6.
[0041] Understandably, when the car body 5 rolls, it will collide with the roll stop, which will transfer the rolling force to the bogie. The bogie and motor frame 3 are connected by a vertical stop 4, and the rolling force will be transferred to the motor frame 3 through the vertical stop 4. The motor frame 3 will then transfer the rolling force to the track beam 6 through the positioning wheel 31. In this invention, the car body 5 is hinged to the bogie, releasing the rolling motion of the car body 5. The crosswind moment is balanced by the vehicle's gravity moment, reducing the bogie wheel load reduction rate. At the same time, the roll stop attenuates the rolling motion of the car body 5 and prevents the vehicle from exceeding the clearance, ensuring the stability of the vehicle operation. In addition, the vertical stop 4 and the positioning wheel 31 transfer the force generated by the rolling of the car body 5 to the track beam 6, preventing the bogie from overturning and ensuring the reliability of the structure.
[0042] Furthermore, such as Figure 2 As shown, the bogie includes a frame 1 and a suspension device 2. The suspension device 2 is hinged to the lower end of the frame 1 and is used to connect the car body 5, as shown. Figure 4 , 5 As shown, the roll stop includes a first roll stop 14, which is arranged between the frame 1 and the suspension device 2. The first roll stop 14 is used to directly act on the suspension device 2 to limit the rotation angle of the suspension device 2.
[0043] This utility model, by setting a first side roll stop 14, can limit the rotation angle of the suspension device 2, thereby limiting the rotation angle of the vehicle body 5.
[0044] Furthermore, such as Figure 4 , 5 As shown, the roll stop includes a second roll stop 15, which is arranged at the bottom of the frame 1. The second roll stop 15 is used to directly act on the vehicle body 5 to limit the rotation angle of the vehicle body 5.
[0045] This utility model provides a second roll stop 15, which, together with the first roll stop 14, restricts the vehicle body 5 and the suspension device 2 respectively. The second roll stop 15 and the first roll stop 14 can share the force generated by the roll, ensuring the stopping effect and preventing the second roll stop 15 and the first roll stop 14 from being subjected to excessive force.
[0046] Furthermore, such as Figure 4 , 5As shown, the suspension device 2 includes a center pin 21 and a bolster 22. A groove 11 and a rotating hole are opened at the bottom of the frame 1. The rotating hole is arranged above the groove 11. The bolster 22 is arranged at the top inside the vehicle body 5 to support the vehicle body 5. A round pin 13 is set in the rotating hole. The top of the center pin 21 is rotatably connected to the round pin 13. Two first side roll stops 14 are provided. The first side roll stops 14 are arranged on the groove wall of the groove 11. The two first side roll stops 14 are symmetrically arranged in the groove 11. The second side roll stops 15 are arranged outside the groove 11, close to the edge of the frame 1. A total of four second side roll stops 15 are provided, arranged symmetrically in pairs.
[0047] The first side roll stop 14 of this utility model is arranged on the groove wall of the groove 11, and the second side roll stop 15 is arranged outside the groove 11, that is, at the bottom end of the frame 1. The positions of the first side roll stop 14 and the second side roll stop 15 can reduce the influence of the outside world to a certain extent, which is beneficial to improving the service life.
[0048] Furthermore, such as Figure 8 , 9 As shown, the first side roll stop 14 includes a first stop seat 141 and a first buffer body 142. The first stop seat 141 is fixedly disposed on the groove wall of the groove 11. Two limiting plates 143 are disposed on the first stop seat 141. The first buffer body 142 is fixedly disposed between the two limiting plates 143 of the first stop seat 141. The height of the first buffer body 142 is always greater than the height of the limiting plates 143 during the compression process.
[0049] The first side roll stop 14 of this utility model is provided with a limiting plate 143. The limiting plate 143 can restrict the side of the first buffer body 142, reduce the axial compression of the first buffer body 142, and prevent the first buffer body 142 from being damaged under a large impact.
[0050] Furthermore, such as Figure 6 , 7 As shown, the second side roll stop 15 includes a second stop seat 151 and a second buffer body 152. The second stop seat 151 is fixedly disposed on the lower end face of the frame 1. A limiting ring 153 is disposed on the second stop seat 151. The second buffer body 152 is fixedly disposed inside the limiting ring 153 of the second stop seat 151. The height of the second buffer body 152 is always greater than the height of the limiting ring 153 during the compression process.
[0051] The second side roll stop 15 of this utility model is provided with a limiting ring 153. The limiting ring 153 can restrict the outer peripheral surface of the second buffer body 152, reduce the axial compression of the second buffer body 152, and prevent the second buffer body 152 from being damaged under a large impact.
[0052] The first stop seat 141, the second stop seat 151, the limit plate 143, and the limit ring 153 are all made of metal, while the first buffer body 142 and the second buffer body 152 are made of elastic rubber.
[0053] Furthermore, such as Figure 4 As shown, the bottom of the center pin 21 is hinged to the bolster 22. Four elastic elements 24 are provided on the top of the bolster 22. The top of each elastic element 24 engages with the top of the vehicle body 5. Lateral stops 23 are provided on both sides of the bolster 22. These lateral stops engage with the side walls of the vehicle body 5 and directly act on the vehicle body 5 to limit its rotation angle. The structure of the lateral stops 23 is the same as that of the second roll stop 15.
[0054] This utility model provides a lateral stop 23, which, together with the roll stop, can limit and buffer the roll of the vehicle body 5.
[0055] In some embodiments, as Figure 4 As shown, a shock absorber 17 is installed at the bottom of the frame 1. One end of the shock absorber 17 is rotatably connected to the frame 1, and the other end of the shock absorber 17 is used to connect to the vehicle body 5. The shock absorber 17 is a hydraulic shock absorber 17.
[0056] By incorporating a shock absorber, this invention enables the frame 1 to be buffered by the action of the shock absorber 17 when the vehicle body 5 interacts with the roll stop, thus preventing the frame 1 from overturning and being damaged under a large roll force.
[0057] In some embodiments, as Figure 3 As shown, anti-derailment limiting mechanisms 12 are provided at the four corners near the top of the frame 1. The anti-derailment limiting mechanism 12 includes an anti-derailment limiting seat and a limiting wheel. The limiting wheel is rotatably connected to the anti-derailment limiting seat, and a gap is provided between the limiting wheel and the inner wall of the track beam 6.
[0058] By setting an anti-derailment limiting mechanism 12, this utility model can prevent the wheels 16 on the bogie from derailing from the track in the track beam 6.
[0059] Based on the above bogie structure, such as Figure 1 As shown, this utility model also provides an air track system, including a track beam 6 and a car body 5. The track beam 6 is a closed box-shaped structure. The bogie frame 1 is set inside the track beam 6. A linear motor is set on the top of the motor frame 3. A secondary induction track is set on the top inside the track beam 6. The linear motor and the secondary induction track cooperate to drive the car body 5. Two tracks are set at the bottom inside the track beam 6. Wheels 16 are set on both sides of the frame 1. The wheels 16 are arranged on the tracks. The lower end of the frame 1 extends out of the track beam 6 and is connected to a suspension device 2. The car body 5 is connected to the suspension device 2.
[0060] The track beam 6 of this monorail system adopts a closed box-type structure to meet the protection requirements of extreme weather conditions such as rain and snow, effectively protecting the facilities and equipment inside the beam, isolating them from the external environment, and reducing the impact of rain and snow. This monorail system enhances the stability and safety of the monorail vehicles under high wind conditions through refined vehicle system design. Based on the structural characteristics of suspended monorail vehicles, it releases the lateral roll motion of the car body 5, balances the crosswind moment through the vehicle's gravity moment, reduces the bogie wheel load reduction rate, and simultaneously employs vibration damping measures to attenuate the lateral roll motion of the car body 5, ensuring vehicle operational stability. Side roll stops prevent the vehicle from exceeding the clearance limits, while vertical stops prevent the bogie from overturning.
