[0002] The existing mountain transportation systems mainly include mountain wheeled transporters, tracked transporters, rail transporters, and aerial ropeway transportation systems. Their disadvantages are as follows: Mountain wheeled transporters and tracked transporters have certain requirements for the terrain and are not suitable for steep and irregular terrains without roads; Rail transporters require a large amount of capital investment to build special tracks, the tracks occupy space, and they need to be towed by electric cars or gasoline (diesel) vehicles; The driving devices of aerial ropeway transportation systems include hand-cranked and electric-driven types. The hand-cranked type is not conducive to long-distance precise control, and the electric-driven type requires laying cables or installing diesel generators and then driving through a hoisting mechanism, consuming more energy and having poor control performance.

[0003] Therefore, our side plans to develop an intelligent cableway-type mountain transportation device. During the downhill process of the trolley in this transportation device, the motor generates electricity, and when going uphill, the motor is in an electric state, using the electricity generated downhill for driving, saving energy or even not consuming energy. In this way, various problems existing in the existing mountain transportation systems can be well solved.

[0004] However, at present, there is no intelligent trolley with the above functions that can be directly put into use. Therefore, researching and designing an intelligent trolley with the above functions has become a technical problem to be solved urgently. Summary of the Invention

The intelligent trolley can be disassembled and installed on multiple ropeways for repeated use.

[0006] The technical solution of the present invention: A structure of an intelligent trolley includes a bracket. An active wheel system is arranged on the upper part of the side of the bracket, and a tensioning wheel system is arranged below the active wheel system.

[0008] In the aforementioned intelligent trolley structure, the controller and the servo system are electrically connected to the remote controller.

[0009] In the aforementioned intelligent trolley structure, the number of the remote controllers is set to 2.

[0010] In the aforementioned intelligent trolley structure, when the number of the driving wheel system and the tension wheel system is different, the driving wheel system and the tension wheel system are arranged in a staggered manner; when the number of the driving wheel system and the tension wheel system is the same, the driving wheel system and the tension wheel system are arranged symmetrically.

[0011] In the aforementioned intelligent trolley structure, the goods hoisting device is a hook rotatably connected to the bracket.

[0012] In the aforementioned intelligent trolley structure, U-shaped card slots are arranged on both the driving wheel and the tension wheel.

[0013] Advantages of the present invention: Compared with the prior art, the intelligent trolley structure of the present invention is provided with a driving wheel system and a tension wheel system. The driving wheel system is composed of a reducer, a driving wheel, a motor, a controller, and a storage battery. During the downhill process, the controller controls the motor to be in a power generation state. The intelligent trolley rolls through the driving wheel under the action of its own weight and the weight of the transported goods, drives the reducer and the motor to rotate, generates electricity through the motor, and stores the electric energy in the storage battery.

Detailed implementation manners

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but it shall not be used as a basis for limiting the present invention.

[0022] Embodiment of the present invention: A structure of an intelligent vehicle, as Figures 1-5 shown, includes a support 1. A driving wheel system 2 is arranged on the upper part of the side of the support 1, and a tensioning wheel system 3 is arranged below the driving wheel system 2. The driving wheel system 2 includes a driving wheel 202, the driving wheel 202 is sleeved on a wheel axle, the other end of the wheel axle is rotatably connected to a reducer 201, the reducer 201 is fixed on the support 1, the reducer 201 is rotatably connected to a motor 203, the motor 203 is electrically connected to a controller 204 and a storage battery 205, and the controller 204 and the storage battery 205 can be fixed on the support 1 or can be fixed on the motor 203. A cargo hoisting device is arranged at the bottom of the support 1. During use, the structure of the intelligent vehicle is erected on a steel wire rope 6, wherein the driving wheel system 2 is supported on the steel wire rope 6, and the tensioning wheel system 3 is in contact with the steel wire rope 6, and the driving wheel 202 in the driving wheel system 2 is supported on the steel wire rope 6.

[0023] The tensioning wheel system 3 includes a tensioning wheel 301, and the bottom of the steel wire rope 6 is in contact with the surface of the tensioning wheel 301 during use. The tensioning wheel 301 is sleeved on a wheel axle 303, both ends of the wheel axle 303 are movably clamped into vertically arranged chutes 101 on the support 1, a servo system 302 is further installed on the support 1 below the chutes 101, the output end of the servo system 302 is fixedly connected to a U-shaped support frame 304, both ends of the wheel axle 303 are supported on the U-shaped support frame 304, and the servo system 302 is electrically connected to the storage battery 205 and the controller 204.

[0024] The controller 204 and the servo system 302 are electrically connected to the remote controller 4. Instructions are sent from the remote controller 4 to the controller 204 and the servo system 302, thereby controlling the operation of the driving wheel system 2 and the tensioning wheel system 3.

[0025] The number of the remote controllers 4 is set to 2, which are respectively arranged at the two terminal poles 7. The start and stop of the intelligent vehicle can be controlled respectively at the two terminal poles 7.

[0026] When the numbers of the driving wheel system 2 and the tensioning wheel system 3 are different, the driving wheel system 2 and the tensioning wheel system 3 are arranged in a staggered manner. There are 2 sets or more of the driving wheel system 2 and 1 set or more of the tensioning wheel system 3. This structure is mainly applicable to the round-trip transportation between high and low places in the mountain. The advantage of the staggered arrangement is that the tensioning force adjustment range of the tensioning wheel system 3 on the steel wire rope 6 is relatively large, avoiding the excessive speed of the intelligent vehicle during the downhill process. Moreover, multiple sets of the driving wheel system 2 can make the intelligent vehicle more stable and avoid derailment.

[0027] In addition to being used for mountain transportation, the structure of the intelligent vehicle of the present invention can also be used for flat ground transportation. During flat ground transportation, there is only 1 set of both the driving wheel system 2 and the tensioning wheel system 3. The driving wheel 202 and the tensioning wheel 301 are engaged together above and below the steel wire rope 6, and the motor 203 only has the electric function, as Figure 4 shown.

[0028] The cargo hoisting device is a hook 5 rotatably connected to the bracket 1, and the cargo to be transported is hung by the hook 5.

[0029] Both the driving wheel 202 and the tensioning wheel 301 are provided with U-shaped card slots. During operation, the steel wire rope 6 is stuck in the U-shaped card slots of the driving wheel 202 and the tensioning wheel 301, preventing the driving wheel 202 and the tensioning wheel 301 from detaching from the steel wire rope.

[0030] The structure of the intelligent vehicle of the present invention can be applied to an intelligent zip-line mountain transportation device to transport the cargo at the top or middle of the mountain to the foot of the mountain. In addition to including the structure of the intelligent vehicle, the intelligent zip-line mountain transportation device further includes a steel wire rope 6 and terminal poles 7. The two terminal poles 7 are respectively arranged at the top and the foot of the mountain, and are connected by the steel wire rope 6 between the two terminal poles 7. The intelligent vehicle structure is mounted on the steel wire rope 6.

[0031] During use, hang the object to be transported on the hook 5 at the mountaintop or mountainside, press the down button of the remote controller 4, the controller 204 controls the motor 203 to be in the power generation state, the output end of the servo system 302 retracts, resulting in a reduced pressing force of the U-shaped support frame 304 on the wheel axle 303, such that the tension pulley 301 and the steel wire rope 6 are in a natural fitting state or maintain an appropriate pressure. Under the gravity of the intelligent trolley and the goods, the driving wheel 202 rolls downward on the steel wire rope 6, driving the intelligent trolley to slide downward along the steel wire rope 6 with acceleration. When the driving wheel 202 rolls, it drives the reducer 201 to act through its fixed shaft, and drives the motor 203 to rotate for power generation to charge the storage battery 205. When the rotation speed of the motor 203 reaches the preset value, the controller 204 controls the rotation speed of the motor 203 not to increase anymore, and keeps the driving wheel 202 rolling at a constant speed through the reducer 201, and the intelligent trolley structure descends at a preset speed at a constant speed; meanwhile, the servo system 302 extends outwards, pushes the wheel axle 303 upward through the U-shaped support frame 304, such that the wheel axle 303 moves upward along the sliding groove 101, making the tension pulley 301 press the steel wire rope 6 tightly, preventing the driving wheel 202 from slipping on the steel wire rope 6. When the tension force of the tension pulley 301 pressing on the steel wire rope 6 is too large, the intelligent trolley structure decelerates, the rotation speed of the motor 203 decreases, the controller 204 transmits a signal to the servo system 302, the servo system 302 retracts inwards, reducing the thrust on the wheel axle 303, and the intelligent trolley structure accelerates, and so on, making the intelligent trolley structure descend at a preset speed at a constant speed. When the storage battery 205 is fully charged, the motor 203 stops generating electricity. The servo system 302 is powered by the storage battery 205, and the storage battery 205 can be removed for charging.

[0032] When the intelligent trolley structure reaches the foot of the mountain (or the mountaintop or the location of the object to be transported at the mountainside), press the stop button of another remote controller 4 at the foot of the mountain (or the mountaintop or the location of the object to be transported at the mountainside), the controller 204 controls the motor 203 to decelerate, and drives the driving wheel 202 to decelerate until it stops rolling through the reducer 201; meanwhile, the servo system 302 pushes the wheel axle 303, such that the tension pulley 301 presses the steel wire rope 6 tightly until the intelligent trolley structure stops. In addition, when the intelligent trolley structure fails to stop in time, the damping mechanism on the steel wire rope 6 can also decelerate and stop the intelligent trolley structure.

[0033] After removing the object to be transported from the hook 5 at the foot of the mountain, press the up button of another remote controller 4 at the foot of the mountain. Powered by the storage battery 205, the controller 204 controls the motor 203 to be in the electric state, the servo system 302 unloads the pressing force on the wheel axle 303, and the tension pulley 301 and the steel wire rope 6 are in a natural fitting state or maintain an appropriate pressure. The motor 203 drives the driving wheel 202 to roll through the reducer 201 until the intelligent trolley structure ascends at a preset speed at a constant speed.
