In the following description, specific details such as specific configurations and components are provided only to help the embodiments of the present application be fully understood. Accordingly, it will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.
In addition, the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
With reference to fig. 1 to 6, the present application proposes a rail carrying system comprising: a track 100 and a wheeled vehicle 200 capable of running on the track 100.
The track 100 is composed of two rails, a first rail 110 and a second rail 120; the track 100 comprises a first track segment 100a and a second track segment 100 b; wherein the second track segment 100b is a curved track curved to one side.
The wheeled vehicle 200 includes: a frame 230, a wheel axle 240, a first side wheel 210 adapted to the first rail 110, a second side wheel 220 adapted to the second rail 120; the first side wheels 210 and the second side wheels 220 are mounted in pairs on the wheel shafts 240 and rotate in synchronization with the corresponding wheel shafts 240. The wheeled vehicle 200 is provided with at least two wheel pairs and two wheel axles 240. Specifically, the wheeled vehicle 200 shown in fig. 3 has a two-wheel axle 240 and two pairs of wheels consisting of a first side wheel 210 and a second side wheel 220.
In the prior art, after a carrying vehicle enters a curve, relative sliding occurs between wheels and a guide rail due to different lengths of an inner rail and an outer rail, so that the wear of the guide rail and the wheels is increased, and the required driving power is larger.
In the present embodiment, referring to fig. 3, the first side wheel 210 is provided with at least a first wheel portion 211 and a second wheel portion 212 at different positions along the wheel axis 240 in the axial direction, and both have different wheel diameters; the first guide rail 110 of the first track segment 100a and the first guide rail 110 of the second track segment 100b are arranged in a transversely staggered manner; the first rail 110 of the first rail segment 100a corresponds to a lateral position of the first wheel section 211, and the first rail 110 of the second rail segment 100b corresponds to a lateral position of the second wheel section 212, such that the first wheel section 211 is in contact engagement with the first rail 110 at the first rail segment 100a, and the second wheel section 212 is in contact engagement with the first rail 110 at the second rail segment 100 b.
When the wheeled vehicle 200 enters the second track segment 100b from the first track segment 100a, the first side wheels 210 are switched from the first wheel section 211 to the second wheel section 212 on the first rail 110 side, thereby achieving the switching of the wheel diameters. In the present embodiment, the first guide rail 110 is located outside or inside the second track segment 100 b.
In some embodiments, referring to fig. 2, the first rail 110 is located outside the second rail segment 100b, such that when moving on the second rail segment 100b, the second wheel portion 212 of the first side wheel 210 is in contact with the first rail 110 and the wheel diameter of the second wheel portion 212 is larger than the wheel diameter of the second side wheel 220 coaxial therewith. As wheeled vehicle 200 moves on second track segment 100b, the speed of first side wheels 210 on the outboard rail is greater than the speed of second side wheels 220 on the inboard rail, thereby reducing relative slippage between the wheels and the rail.
In some embodiments, referring to fig. 4, the first rail 110 is located inside the second rail segment 100b, such that when moving on the second rail segment 100b, the second wheel portion 212 of the first side wheel 210 is in contact with the first rail 110 and the wheel diameter of the second wheel portion 212 is smaller than the wheel diameter of the second side wheel 220 coaxial therewith; as wheeled vehicle 200 moves on second track segment 100b, first side wheels 210 travel at a slower rate on the inboard side rail than second side wheels 220 travel on the outboard side rail, thereby reducing relative slippage between the wheels and the rail.
The diameter of the wheel is the diameter of the contact fit position of the wheel and the guide rail, and when the contact position on the wheel changes, the diameter of the wheel may change. In the embodiment of the present application, the second side wheel 220 is in contact fit with the second rail 120, and the second side wheel 220 may also be provided with a plurality of wheel portions with different wheel diameters, and different wheel portions are adopted for contact fit in different track sections, so as to change the wheel diameter of the second side wheel 220. The solution of the embodiment of the present application does not limit the second side wheel 220 to have the same wheel diameter in the first track segment 100a and the second track segment 100 b. In some embodiments, the wheel diameter remains the same as the second side wheel 220 is advanced on the second rail 120.
When the wheeled vehicle 200 enters the second track segment 100b from the first track segment 100a, the first side wheel 210 is switched from the first wheel portion 211 to the second wheel portion 212 to be in contact with the first rail 110, so that the wheel diameter is switched, so that the relative sliding between the wheel and the rail is reduced in the curved second track segment 100b, and the wear of the rail and the wheel and the required driving power are reduced.
In some embodiments, referring to fig. 1, the first track segment 100a is a linear track; the first wheel portion 211 has a wheel diameter equal to a wheel diameter of the second side wheel 220 coaxial therewith when moving on the first track segment 100 a. Therefore, when running on the first track segment 100a, the advancing speed of the wheels on both sides is the same, reducing the relative slip between the wheels and the guide rail.
In some embodiments, the first track segment 100a is a curved track that curves to one side, and in the opposite direction of the curve of the second track segment 100 b; at this time, the first track segment 100a and the second track segment 100b together form an S-turn; in some embodiments, the first track 110 is located outside the second track segment 100b, such that the wheel diameter of the first wheel portion 211 is smaller than the wheel diameter of the second side wheel 220 coaxial therewith when moving on the first track segment 100 a; in some embodiments, referring to fig. 5, the first track 110 is located inside the second track segment 100b, such that the first wheel portion 211 has a wheel diameter larger than the wheel diameter of the second side wheel 220 coaxial therewith when moving on the first track segment 100 a. As first rail segment 100a advances, first wheel portion 211 engages first rail 110 in contact with first side wheel 210, and first side wheel 210 advances on the inboard side rail at a slower speed than second side wheel 220, thereby reducing relative slip between the wheels and the rail.
In some embodiments, referring to fig. 6, the first track segment 100a is a curved track that curves to one side; the first track segment 100a and the second track segment 100b have the same bending direction, and the bending radius of the first track segment 100a is different from the bending radius of the second track segment 100 b.
The track 100 according to the present embodiment includes at least a first track segment 100a and a second track segment 100b, and the first guide rail 110 is laterally offset between the two track segments; the first guide rail 110 of the first rail section 100a corresponds to the lateral position of the first wheel portion 211, the first guide rail 110 of the second rail section 100b corresponds to the lateral position of the second wheel portion 212, so that the first wheel portion 211 is in contact fit with the first guide rail 110 in the first rail section 100a, and the second wheel portion 212 is in contact fit with the first guide rail 110 in the second rail section 100b, thereby changing the wheel diameters of the first side wheel 210 in the two rail sections to adapt to the two rails respectively.
In the embodiment of the application, for the curved track, the wheel diameter of the wheels on the outer side guide rail is larger than that of the wheels on the inner side track, and the wheel diameters of the wheels on two sides of the linear track are the same. The bending directions and/or the bending radii of different track sections are different, and the technical scheme provided in the embodiment of the application changes the wheel diameters of the wheels by switching the wheel parts, matched with the guide rails, on the first side wheels 210, so that the track section is suitable for different track sections.
In some embodiments, the ratio D1/D2 of the wheel diameter D1 of the second wheel portion 212 to the wheel diameter D2 of the coaxial second side wheel 220 is equal to the ratio D1/D2 of the bending radius D1 of the first rail 110 of the second rail segment 100b to the bending radius D2 of the second rail 120 of the second rail segment 100b when moving on the second rail segment 100 b.
In some embodiments, the ratio D3/D4 of the wheel diameter D3 of the first wheel portion 211 to the wheel diameter D4 of the coaxial second side wheel 220 is equal to the ratio D3/D4 of the bending radius D3 of the first rail 110 of the first rail segment 100a to the bending radius D4 of the second rail 120 of the first rail segment 100a when moving on the first rail segment 100 a.
On the curved track, the ratio of the wheel diameter of the outer wheels to the wheel diameter of the inner wheels is equal to the ratio of the bending radius of the outer guide rail to the bending radius of the inner guide rail, so that the linear speeds of the inner wheels and the outer wheels are approximately the same as the length of the guide rail, and the relative sliding between the wheels and the guide rail is effectively reduced.
In some embodiments, the frame 230 of the wheeled vehicle 200 is provided with a tank, box, or plate.
