Description

Technical Field

[0001] This utility model relates to the field of transportation equipment for hilly and mountainous areas, and in particular to a planetary wheel type monorail transport vehicle. Background Technology

[0002] Hilly and mountainous areas account for approximately 43% of China's total land area, and these regions are major cultivation areas for cash crops such as vegetables, fruits, and tea. However, the complex terrain and the loss of rural labor have led to low efficiency and high costs associated with traditional manual transportation, creating an urgent need for mechanized transportation equipment to improve production efficiency. Mountain monorail transport vehicles, capable of adapting to steep slopes, curves, and other complex terrain along guide rails, have become an important tool for transportation in hilly and mountainous areas.

[0003] Traditional mountain monorail transport vehicles generally adopt a transmission structure of "internal combustion engine-clutch-reducer-single drive wheel", which has the following significant drawbacks:

[0004] Complex structure and low degree of automation: Internal combustion engines require mechanical components such as clutches and gearboxes, resulting in high system maintenance costs and high failure rates. They also rely on manual operation for starting and stopping, making it difficult to achieve automated control.

[0005] High operational difficulty and safety risks: The power output of internal combustion engines is non-linear, requiring operators to have professional skills to control start-stop, speed adjustment and braking. Especially in complex working conditions such as steep slopes and slippery conditions, improper operation can easily lead to safety accidents.

[0006] Low energy efficiency and energy waste: Internal combustion engines have low fuel efficiency, and kinetic energy is directly converted into heat energy loss during braking, which cannot be recovered and reused; at the same time, energy loss of mechanical transmission components (such as clutches) further reduces system efficiency.

[0007] Insufficient environmental adaptability: Internal combustion engines are significantly affected by environments such as low temperature and high altitude. In remote mountainous areas, they are prone to problems such as difficulty in starting and power reduction. Moreover, the emissions pollution does not conform to the development trend of green agriculture.

[0008] There is an urgent need for a new type of drive device to replace the traditional internal combustion engine drive structure in order to meet the needs of efficient transportation in complex terrain, and to simplify the structure and promote the upgrading of mechanized mountain agriculture.

[0043] This embodiment provides a planetary wheel monorail transport vehicle. Please refer to [reference needed]. Figures 1-10 The system includes a base plate 1, a battery pack 2, a drive motor, and a planetary gear train 3. A drive wheel 4 is mounted on the base plate 1 and is connected to a guide rail via a transmission connection. Preferably, the drive wheel 4 is meshed with the guide rail.

The base of the planetary gear train 3 is fixed to the base plate 1, and the planet carrier 5 inside the planetary gear train 3 serves as the power output end, transmitting the power of the drive motor to the drive wheel 4 after speed change via the planetary gear train 3. The drive wheel 4 is connected to the guide rail, and through its own rotation, it meshes with the guide rail, converting the power of the planet carrier 5 into linear motion of the base plate 1 along the guide rail, thereby achieving synchronous movement of the transport vehicle. The drive motor of this invention outputs power through the planet carrier 5, and by utilizing the speed change transmission characteristics of the planetary gear train 3, it can achieve high torque output and speed regulation, and can more efficiently transmit the power of the drive motor to the drive wheel 4, adapting to the high load requirements of mountain rail transport. This utility model also uses the electrical energy in battery pack 2 as a power source to provide power to the drive motor, avoiding the complex piping and energy loss of traditional fuel power, and providing stable power supply and good power stability.

The planet gears 9 are arranged around the sun gear 8, and the teeth on the planet gears 9 mesh with the sun gear 8 and also with the internal teeth of the ring gear 10. The output shaft of the first motor 6 is fixedly connected to the sun gear 8, and the second motor 7 is drivenly connected to the ring gear 10.

[0046] In one embodiment, the system further includes a first coupling 11, a second coupling 12, and a transmission gear 13. Both the first coupling 11 and the second coupling 12 are preferably flexible pin couplings. The output shaft of the first motor 6 is coaxially and fixedly connected to the sun gear 8 via the first coupling 11, and the output shaft of the first motor 6 drives the sun gear 8 to rotate via the first coupling 11.

When the second motor 7 drives the transmission gear 13 to rotate via the second coupling 12, the transmission gear 13 acts as the driving gear, and the gear ring 10 acts as the driven gear; it can synchronously drive the gear ring 10 to rotate.

The second motor 7 is coaxially and fixedly connected to the transmission gear 13 via the second coupling 12, driving the transmission gear 13 to rotate. The transmission gear 13 meshes with the gear ring 10, acting as the driving gear. Its outer outer teeth mesh with the outer teeth of the gear ring 10, forming a gear pair. The second motor 7 drives the gear ring 10 to rotate as the driven gear through the transmission gear 13, forming the second power input. Planet gears 9 are rotatably mounted on the planet carrier 5 via bearings. Their inner teeth mesh with the outer teeth of the sun gear 8, and their outer teeth mesh with the inner teeth of the gear ring 10. The sun gear 8 and the gear ring 10 serve as the dual input ends of the planetary gear system 3, driven to rotate by the first motor 6 and the second motor 7, respectively. Under the meshing action of the sun gear 8 and the gear ring 10, the planet gears 9 simultaneously rotate on their own axis and revolve around the sun gear 8, thereby driving the planet carrier 5 to rotate. The planetary carrier 5, as the sole output end of the planetary gear train 3, converges the dual power from the sun gear 8 and the ring gear 10 through revolution and outputs it to the drive wheel 4. The drive wheel 4 is connected to the guide rail and rotates through the rotational power transmitted by the planetary carrier 5. After meshing with the guide rail, it is converted into linear motion of the base plate 1 along the guide rail, completing the cargo transportation. In this utility model, the first motor 6 drives the sun gear 8, and the second motor 7 drives the ring gear 10 to form a dual power input end. Utilizing the differential characteristics of the planetary gear train 3, torque superposition or speed adjustment can be achieved to adapt to the complex load requirements in mountain transportation.

[0048] In one embodiment, the base plate 1 is an L-shaped plate, comprising a main body 14 and a bent portion 15. Preferably, the main body 14 is horizontally positioned, and the bent portion 15 is perpendicular to the main body 14. The main body 14 and the bent portion 15 are integrally formed from high-strength steel. The top surface of the main body 14 forms an equipment mounting surface, on which the battery pack 2, drive motor, and planetary gear train 3 are all mounted. A load-bearing wheel mounting seat 16 is provided at the bottom of the main body 14, located on the side opposite to the equipment mounting surface. A load-bearing wheel is mounted on the load-bearing wheel mounting seat 16, which rolls against the top of the guide rail to support the gravity load of the base plate 1. Preferably, the load-bearing wheel is mounted on the load-bearing wheel mounting seat 16 via a rotary bearing. The drive wheel 4 is mounted on the bent portion 15 and located on the side of the bent portion 15 facing the guide rail. The drive wheel 4 is connected to the bottom of the guide rail via a transmission connection. Preferably, a rack is fixedly provided at the bottom of the guide rail, and the drive wheel 4 is provided with gear teeth 17 that mesh with the rack. The gear teeth 17 mesh with the rack. Through the continuous meshing of the gear teeth 17 and the rack, the rotational motion of the drive wheel 4 is converted into the linear motion of the base plate 1 along the guide rail.

[0049] In this embodiment, the load-bearing wheel mounting base 16 is a long strip structure, and the length direction of the long strip structure extends along the preset travel direction of the base plate 1; at least two load-bearing wheels are provided on the load-bearing wheel mounting base 16, and each load-bearing wheel is evenly arranged along the length direction of the load-bearing wheel mounting base 16. The multiple load-bearing wheels can provide stable support for the base plate 1.

[0050] In one embodiment, a reducer 18 is further included. The input shaft of the reducer 18 is coaxially and fixedly connected to the output shaft of the planetary carrier 5. Preferably, the planetary carrier 5 is fixedly connected to the input shaft of the reducer 18 via a third coupling 24. The third coupling 24 is preferably a flexible sleeve pin coupling. The output shaft of the reducer 18 is coaxially and fixedly connected to the drive wheel 4. Preferably, the reducer 18 is a parallel shaft reducer, with its input and output shafts parallel and located on the same vertical line. The housing of the reducer 18 has a rectangular structure, and the housing of the reducer 18 is fixedly connected to the base plate 1 by bolts. The reducer 18 reduces and increases the torque of the rotational power output from the planetary carrier 5 to meet the high torque requirements of the drive wheel 4 when it travels on the guide rail.

[0051] In one embodiment, a motor support base 19 is provided on the base plate 1, and the motor support base 19 has a stepped structure. Preferably, the motor support base 19 is provided on the base plate 1 and is fixedly connected to the base plate 1 by bolts. The motor support base 19 includes two layers of support platforms spaced apart vertically, namely a first support platform and a second support platform. The top surfaces of the two support platforms are horizontally arranged, and the top surfaces of the first support platform and the second support platform are parallel to the top surface of the base plate 1. The first motor 6 is provided on the first support platform, and the second motor 7 is provided on the second support platform. By supporting the first motor 6 and the second motor 7 respectively by the first support platform and the second support platform, the output shaft of the first motor 6 and the output shaft of the second motor 7 are horizontally aligned, that is, the axis of the output shaft of the first motor 6 and the axis of the output shaft of the second motor 7 are horizontally coplanar. The first motor 6 is coaxially fixedly connected to the sun gear 8 through a first coupling 11, and the second motor 7 is coaxially fixedly connected to the transmission gear 13 through a second coupling 12. This invention utilizes the height difference between two support platforms to precisely adjust the motor installation height, ensuring that the output shaft axes of the first motor 6 and the second motor 7 are strictly located in the same horizontal plane. The axes of the transmission gear 13, the sun gear 8, and the gear ring 10 are all located in the same horizontal plane, enabling the transmission gear 13 and the gear ring 10 to mesh at full tooth width. This avoids meshing imbalance caused by the height difference of the axes, improving the smoothness and lifespan of the gear transmission.

[0052] In this embodiment, the first motor 6 is a low-power motor with a brake device, and the second motor 7 is a high-power motor with a brake device. Specifically, brake devices are installed at the output ends of both the first motor 6 and the second motor 7. Each brake device includes a brake seat fixed to the motor housing and radially movable brake pads. The brake pads are controlled by a controller to abut or disengage from the outer circumferential surface of the output shaft. The braking method can be mechanical or electromagnetic. The brake devices on the first motor 6 or the second motor 7 achieve braking and fixation by pressing the brake pads against the corresponding outer circumferential surface of the output shaft.

[0053] Control logic for single / dual motor operating modes:

[0054] Dual-motor operating mode:

[0055] The second motor 7 is coaxially driven with the ring gear 10 of the planetary gear train 3 through the second coupling 12. The first motor 6 is coaxially driven with the sun gear 8 through the first coupling 11. The planet carrier 5 of the planetary gear train 3 is coaxially and fixedly connected to the input shaft of the reducer 18 through the third coupling 24. The output shaft of the reducer 18 is coaxially connected to the drive wheel 4, thereby transmitting the power of the second motor 7 and the first motor 6 to the drive wheel 4 through a two-stage reduction. In the two-stage reduction, the planetary gear train 3 acts as the first stage of reduction, and the reducer 18 forms the second stage of reduction, obtaining the maximum torque output of the dual motors superimposed, which is suitable for heavy-load climbing conditions.

[0056] Single motor operating mode:

[0057] When the second motor 7 is working, the controller controls the brake device of the first motor 6 to be energized, preferably so that the brake pads are pressed against its output shaft to fix it; the output shaft of the first motor 6 is fixed, so that only the second motor 7 is working; the sun gear 8 is stationary, and only the ring gear 10 drives the planetary gear train 3.

[0058] When the first motor 6 is working, the brake device of the second motor 7 is energized, which fixes the output shaft of the second motor 7, thereby enabling the first motor 6 to work alone. The sun gear 8 drives the planetary gear system 3, thus enabling two-speed power conversion to adapt to more road conditions.

[0059] Regenerative braking:

[0060] When the vehicle is downhill, the controller energizes the brake device of the second motor 7, fixing the brake system of the second motor 7 and thus fixing the gear ring 10. The drive wheel 4 drives the planetary carrier 5 to rotate via the reducer 18, which in turn drives the sun gear 8 to rotate in reverse, driving the first motor 6 to rotate in reverse, making the first motor 6 operate as a generator, thereby realizing the recovery of braking energy. The current output by the first motor 6 is converted by the rectifier circuit in the control box 21 and stored in the battery pack 2 through cables, realizing the recovery and utilization of kinetic energy into electrical energy.

[0061] In this invention, both the first motor 6 and the second motor 7 can be controlled independently for motion control. That is, the first motor 6 and the second motor 7 can be independently controlled for start-stop, speed and brake status through the controller. Combined with the two-stage reduction system, the transport vehicle has the adaptive capability of dual-motor high torque output and single-motor energy-saving operation, which can realize the recovery and utilization of kinetic energy and significantly improve the load capacity and range performance under complex working conditions.

[0062] In one embodiment, a guide wheel 20 is also provided on the base plate 1, and the guide wheel 20 is located beside the drive wheel 4; preferably, the guide wheel 20 is located in front of the drive wheel 4 in the direction of travel, and guides the travel direction of the base plate 1 through the guide wheel 20. The rotation axis of the guide wheel 20 can be located on the same horizontal plane as the rotation axis of the drive wheel 4. The guide wheel 20 is rotatably mounted on the base plate 1 through bearings, and is specifically located on the bent portion 15 of the base plate 1, with the guide wheel 20 horizontally aligned with the drive wheel 4. The outer peripheral surface of the guide wheel 20 is used for rolling contact with the guide rail, and the guide wheel 20 can rotate on the guide rail. Specifically, the guide wheel 20 includes a circumferential surface. The guide wheel 20 abuts against the guide rail through the circumferential surface, which is located on the outer periphery of the guide wheel 20. Both the guide wheel 20 and the guide rail can adopt structures in the prior art.

[0063] In one embodiment, a control box 21 is provided on the base plate 1, and a controller is provided in the control box 21. The controller is electrically connected to the drive motor. Preferably, the control box 21 is fixedly connected to the base plate 1 by bolts. The controller is also electrically connected to the first motor 6 and the second motor 7. The controller can control the operating status of the first motor 6 and the second motor 7. The controller is preferably a PLC or a microcontroller control device. The control box 21 is set on the equipment mounting surface, and the battery pack 2, the first motor 6, the second motor 7 and the control box 21 are arranged side by side along the length of the base plate 1.

[0064] In one embodiment, a brake mounting plate is mounted on the bent portion 15 of the base plate 1. The drive wheel 4 is made of 45# steel, the guide wheel 20 is made of 45# steel, and the brake mounting plate is also made of 45# steel. The brake mounting plate is fixedly connected to the base plate 1 by bolts, and a brake device 22 is provided on the brake mounting plate. The brake device 22 includes two brake calipers 23 symmetrically distributed on both sides of the drive wheel 4. The brake calipers 23 are slidably mounted on the brake mounting plate via guide rails, and the extension direction of the guide rails is perpendicular to the axis of the drive wheel 4, ensuring that the brake calipers 23 move in opposite directions along a straight line. The braking device 22 is an electromagnet braking structure. The electromagnet can be fixed to the brake mounting plate. Two brake calipers 23 are connected to the armature of the electromagnet via a linkage rod. When the electromagnet coil is energized, it generates electromagnetic force, attracting the armature and driving the linkage rod to move. This causes the two brake calipers 23 to synchronously approach and abut against the two end faces of the drive wheel 4 along the slide rail, achieving braking through friction. The braking device 22 includes a return spring. When the electromagnet is de-energized, the return spring, located between the brake caliper 23 and the brake mounting plate, releases its elastic potential energy, pushing the brake caliper 23 to move in the opposite direction along the slide rail, away from the end face of the drive wheel 4, thus releasing the brake. The base plate 1 can be connected to a cargo trailer. The cargo trailer is equipped with a rotating device, which rotatably connects the cargo trailer to the guide rail. The base plate 1 enables the cargo trailer to move on the guide rail, and the cargo trailer is equipped with a cargo box for loading.
