Description

Technical Field

[0001] The invention relates to the technical field of empty rails, and in particular to a bogie structure and an empty rail system suitable for harsh environments. Background Art

[0002] Aerial rail transportation systems (such as monorails, suspended rail systems, etc.) face a series of challenges when operating under severe weather conditions such as strong winds, sand, rain and snow: 1. Wind and sand erosion and wear: In strong winds and sand weather, wind and sand particles will cause serious erosion and wear on the tracks of the aerial rail transportation system, shortening the service life of the equipment. Wind and sand may also block key components such as the vehicle's air filter and radiator, affecting the normal operation of the vehicle. In addition, strong winds can cause the vehicle to tilt and affect the stability of the vehicle. 2. Reduced visibility: Strong winds and sand weather causes a significant reduction in visibility, which greatly hinders the driver's vision and increases the safety risk of operation. The driver may find it difficult to accurately judge the track ahead and the surrounding environment, which can easily cause collisions or derailment accidents. 3. Slippery and icy tracks: Rainy and snowy weather makes the track slippery, increasing the braking distance and derailment risk of the train. Therefore, it is necessary to design a bogie structure and aerial rail system that can adapt to harsh environments. Summary of the invention

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] like Figure 1 As shown, the present invention provides a bogie structure suitable for harsh environments, including a bogie, the lower end of the bogie is used to be hinged with a car body 5, a side rolling stopper is arranged on the bogie, and the side rolling stopper is used to limit and buffer the side rolling angle of the car body 5, and a motor frame 3 is arranged above the bogie, and the motor frame 3 is vertically movably connected to the bogie, such as Figure 3 As shown, an elastic vertical stopper 4 is arranged between the bogie and the motor frame 3, and the force of the vehicle body 5 on the side rolling stopper is transmitted to the motor frame 3 through the vertical stopper 4. Positioning wheels 31 are arranged at both ends of the motor frame 3, and the positioning wheels 31 are used to abut against the track beam 6. The positioning wheels 31 are used to transmit the force on the motor frame 3 to the track beam 6. Among them, a plurality of ear plates are arranged at the edge of the motor frame 3, and a connecting rod is fixedly arranged at the upper end of the bogie. The upper end of the connecting rod passes through the ear plate and is fixedly arranged with bolts. The bolts can be welded and fixed to the connecting rod, and the motor frame 3 can move along the axial direction of the connecting rod. The vertical stopper 4 adopts a spring, and the positioning wheel 31 on the motor frame 3 abuts against the top of the track beam 6 under the action of the vertical stopper 4.

[0041] It is understandable that when the car body 5 rolls, the car body 5 will collide with the roll stopper, and the roll stopper will transfer the roll force to the bogie, and the bogie is connected to the motor frame 3 through the vertical stopper 4, and the roll force will be transferred to the motor frame 3 through the vertical stopper 4, and the motor frame 3 will eventually transfer the roll force to the track beam 6 through the positioning wheel 31. The car body 5 of the present invention is hinged to the bogie, which releases the roll movement of the car body 5, balances the side wind torque through the vehicle gravity torque, reduces the bogie wheel weight reduction rate, and at the same time, the roll stopper is set to attenuate the roll movement of the car body 5 and prevent the vehicle from exceeding the limit, thereby ensuring the stability of vehicle operation. In addition, the force generated by the roll of the car body 5 is transferred to the track beam 6 through the vertical stopper 4 and the positioning wheel 31, which can prevent the bogie from overturning and ensure the reliability of the structure.

[0042] Furthermore, if Figure 2 As shown, the bogie includes a frame 1 and a suspension device 2. The suspension device 2 is hinged at the lower end of the frame 1.
