Description

Technical Field

[0001] This utility model relates to the field of agricultural transportation equipment technology, and in particular to a hilly and mountainous traction rail transport vehicle suitable for complex terrain. Background Technology

[0002] The geographical distribution of fruit production in my country exhibits a significant concentration in hilly and mountainous areas. This terrain is naturally characterized by steep slopes and fragmented plots. Coupled with the generally lagging development of basic transportation infrastructure such as field roads, this constitutes a real bottleneck restricting the development of the local fruit industry. The emergence of traction transport vehicles has broken through this bottleneck. These vehicles are powered by electric motors and use steel cables as the traction medium. The cargo vehicle is positioned between tracks, enabling forward, backward, and horizontal turning functions, making them more suitable for the steep slopes and sharp curves characteristic of my country's mountainous terrain. Currently, dual-rail transport vehicles are widely used in hilly and mountainous orchards. Existing technologies mainly employ engine-driven traction vehicles and chain-type circulating cableway systems. However, the single-rail design of the transport vehicle results in a higher center of gravity after loading, making it prone to tilting when encountering uneven road surfaces, causing the track system to bear significant torsional loads. Compared to a single-rail structure, a dual-rail structure with dual support points allows for a more balanced distribution of dynamic loads, significantly improving the lateral stability of the transport vehicle and effectively suppressing the risk of instability in complex terrain. Utility Model Content

[0003] The purpose of this invention is to solve the coordination problem between the structure of the rail transport vehicle and the traction transmission device, and the problem that the transport vehicle is prone to deviating from the predetermined trajectory at curves. By combining the stability advantages of the traction transmission device and the complex terrain adaptability of the rail transport vehicle, this invention provides a hilly and mountainous traction rail transport vehicle device that solves the stability and trajectory control of the transport vehicle under complex terrain.

[0004] According to the first technical solution of this utility model, a hilly and mountainous traction rail transport vehicle includes double rails, a transport vehicle, and a traction device. The double rails are "I"-shaped rails supported by rollers to adapt to complex terrain. The bottom of the transport vehicle is equipped with guide wheels and a traction hook. The transport vehicle is connected to the traction device at both ends of a steel wire rope. The traction device is used to provide power to the transport vehicle to make it reciprocate on the double rails. This utility model solves the technical problems of stability and trajectory control of the transport vehicle under complex terrain.

[0005] To further improve the functionality of the hilly and mountainous traction rail transport vehicle, according to the second technical solution of this utility model, the guide wheel includes a single-sided wheel and a guide wheel running on the first surface of the double rail, and an anti-rollover wheel running on the second surface of the double rail. The guide wheel is used to improve the cornering performance of the transport vehicle and ensure that the wire rope is centered in the horizontal direction. The anti-rollover wheel is used to reduce the risk of vehicle rollover.

[0006] To further enhance the functionality of the hilly and mountainous traction rail transport vehicle, according to the fourth technical solution of this utility model, a wire rope guide wheel and a limit switch are arranged on the double rails. The wire rope guide wheel is used to fix the wire rope track; the limit switch is used to control the start and stop of the traction device.

[0007] As a preferred embodiment, according to the fifth technical solution of this utility model, end wire rope guide wheels and wire rope pressure guide wheels are respectively arranged at both ends of the straight rail. The end wire rope guide wheels and wire rope pressure guide wheels are used to improve the stability of the wire rope trajectory and avoid slippage.

[0008] Preferably, according to the sixth technical solution of this utility model, every [number] times on the turning track... A guide wheel for the curved steel wire rope is arranged in an arc. If the arc of the turning track is less than... In this case, no additional wire rope guide rollers will be installed on the curved track. The wire rope guide rollers on the curved track are used to ensure that the wire rope always stays within the predetermined trajectory, reducing the risk of the wire rope swinging or jumping.

[0009] To further provide the functionality of the hilly and mountainous traction rail transport vehicle, according to the seventh technical solution of this utility model, the transport vehicle is used for loading goods, the transport vehicle includes a floor, a cargo railing is installed above the floor, and the cargo railing is provided with baffles.

[0010] To further improve the functionality of the hilly and mountainous traction rail transport vehicle, according to the eighth technical solution of this utility model, the traction device and the traction hook are connected by a wedge-shaped rope sleeve of the wire rope. The design of separating the traction device from the transport vehicle body is used to reduce the weight of the transport vehicle body itself and significantly increase the cargo capacity of the transport vehicle. The traction hook is composed of a hexagonal nut and a wedge-shaped rope sleeve and has strong tensile strength.

[0011] To further provide the functionality of the hilly and mountainous traction rail transport vehicle, according to the ninth technical solution of this utility model, the traction device includes a base plate, and a controller and a winding wheel pair are included above the base plate. The controller is used to receive the limit switch signal and control the forward and reverse rotation of the motor. The motor transmits power to the reduction gearbox through the clutch, and the reduction gearbox further transmits power to the winding wheel pair. The brake is used for braking.

[0012] Preferably, according to the tenth technical solution of this utility model, the bearing seat supports the active winding wheel and the passive winding wheel respectively. The wire rope between the active winding wheel and the passive winding wheel is wound in a figure-eight pattern to avoid slippage of the wire rope and enhance the traction performance of the traction device. The winding wheel pair is connected to the first traction hook by having the wire rope pass through the wire rope lower guide wheel and the curved wire rope guide wheel at one end. The winding wheel pair is connected to the second traction hook by having the wire rope pass through the end wire rope guide wheel at the other end.

[0013] Beneficial effects: This utility model discloses a hilly and mountainous traction rail transport vehicle that transmits power to the transport vehicle purely through a high-strength steel wire rope. The motor and gearbox serve as the engine head, separated from the transport vehicle, with power transmitted from the motor to the transport vehicle via the steel wire rope. This separation design minimizes the vehicle's weight, significantly increasing the maximum load capacity, thus meeting the needs of my country's complex geographical structure and orchard agriculture, and enhancing the adaptability of the traction transport vehicle to complex terrain. Secondly, the steel wire rope between the active and passive reels uses an "8"-shaped winding method, significantly increasing the frictional contact area of ​​the steel wire rope, preventing slippage, and enhancing traction. Finally, the coordinated integrated design of the guide wheels ensures that the steel wire rope always remains within the predetermined trajectory during operation, reducing safety hazards.
