DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention 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 invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] In order to solve the problems of limited load, roller slippage, and unstable vertical left and right swaying of monorail vehicles, and expand its application scenarios, a system for driving and operating a monorail vehicle is implemented, which effectively enhances the monorail vehicle's own carrying capacity and ensures the smoothness and safety of the monorail vehicle's operation process; the size of the monorail vehicle can also be adjusted and assembled according to the width and height of the driving track. It can not only be used on the construction ground, but also for aerial transfer and transportation needs, and is easy to promote and apply.

[0039] The present embodiment relates to a method for driving and operating a monorail vehicle, including a power drive system, a travel track, a support system, a vertical clamping system, and a remote control system.

[0040] Please refer to Figure 1-Figure 2 The power drive system includes bolts 3, brackets 5, drive motors 4, main drive wheels 18, main wheel coaxial gears 20, slave wheels 16, slave wheel coaxial gears 6 and wheel sleeves formed by polyurethane coating. A motor that meets the power requirements can be selected according to the load to be borne. The motor 4 is fixed on the supporting keel 9 through bolts 3 and brackets 5. The motor 4 drives the main drive wheel 18 to rotate and walk; at the same time, the main wheel coaxial gear 20 also rotates synchronously to drive the changing gear 27 to rotate in opposite directions, and the changing gear 27 rotates in opposite directions to drive the slave wheel coaxial gear 6 to change direction, so as to realize the synchronous rotation of the slave wheel 16 and effectively disperse the load borne by the main drive wheel 18; the surfaces of the main drive wheel 18 and the slave wheel 16 are coated with polyurethane material or polyurethane material or polyoxymethylene to increase the friction between them and the track surface and prevent them from slipping.

[0041] The walking track includes an upper track flange plate 25, a web plate 26 and a lower track flange plate 12. The upper track flange plate 25 is in direct contact with the driving wheel, providing a rolling interface and a load-bearing support surface for the driving wheel; the web plate 26 supports the upper track flange plate 25 and transfers the load gravity to the lower track flange plate 12 at the same time, and the roller 8 of the vertical clamping system acts on the web plate 26; the lower track flange plate 12 bears the weight of the support wheel 13, thereby reducing the load on the main driving wheel 18 and avoiding excessive load on the main driving wheel, resulting in broken axle, slipping and burning of electrical circuits; baffles 10 are welded to the ends of both sides of the lower flange plate 12 to prevent the support wheel 13 from slipping out.

[0042] The support system includes a support keel 9, a support wheel 13, an axle 24, a bolt hole 11, a panel 19 and a side steel plate 2. The support wheel 13 is installed on the lower inner side of the support keel 9 through the axle 24, and it bears part of the upper load. When working, the support wheel 13 rolls on the interface of the lower flange plate 12, and the end baffles 10 on both sides of the lower flange plate 12 can assist in preventing deviation; the bolt hole 11 is used for hanging and carrying during the installation of the drive system; the panel 19 is installed on the upper part of the driving power device, which has a safety protection function. The fastening components of the load objects can be placed or installed and welded thereon as needed, and it can also effectively prevent debris and pollution from entering and affecting the driving wheel; the side steel plate 2 is fixed to the support keel 9 by bolts 3, and the main driving wheel 18, the changing gear 27, and the two ends of the axle of the coaxial gear 6 of the slave wheel are fixed on the side steel plate 2.

[0043] Please refer to Figure 3The vertical clamping system includes a longitudinal steel rib 7, a roller fixing frame 23, a clamping roller 8 and a locking hole 28. The two ends of the longitudinal steel rib 7 are fixed to the supporting keel 9 through the locking hole 28. The clamping roller 8 is installed on the roller fixing frame 23. When working, the clamping roller 8 rolls close to the web 26, which effectively prevents the drive system from running off the track and prevents the drive system from swinging vertically left and right. The roller fixing frame 23 is welded on the longitudinal steel rib 7 to provide fixed support for the clamping roller 8.

[0044] Please refer to Figure 4 The remote control system is composed of a signal transceiver 21 on a driving motor 4, a controller handle and a signal transceiver 33 thereon; a forward button 29, a stop button 30, a reverse button 31, and a power-on rotary switch 32 are arranged on the controller handle. By operating the buttons on the controller handle, the rail vehicle can be controlled.

[0045] In some preferred embodiments, in order to enhance the safety of the system, a fault detection device for a monorail vehicle is also included, which includes multiple sensors and a fault detection control unit. The sensors include but are not limited to temperature sensors, vibration sensors, position sensors and current sensors, which are respectively installed on key components such as the drive device 4, the support wheel 13 and the electrical circuit. These sensors monitor the operating status of their respective components in real time and transmit the data to the fault detection control unit. The fault detection control unit evaluates the operating status of the rail vehicle in real time by analyzing the sensor data. Once abnormal data such as overheating, abnormal vibration, position deviation or abnormal current is detected, the control unit will trigger an early warning signal and take corresponding safety measures such as deceleration, parking or emergency braking according to the type of fault. In addition, the fault detection control unit can also record fault data to provide a reference for subsequent maintenance and repair. This fault detection mechanism improves the operating safety and reliability of the rail vehicle. In some preferred embodiments, an emergency stop device is also included. The emergency stop device includes an emergency stop switch and a control unit electrically connected to the switch. The emergency stop switch is set at a position that is easy for the operator to reach, such as an operating panel or a remote control device. When the operator activates the emergency stop switch, the control unit immediately cuts off the power supply to the drive motor, so that the rail vehicle stops running quickly and safely. In addition, the control unit is also equipped with an emergency braking mechanism, such as a mechanical brake or an electromagnetic brake, which is arranged on the main drive wheel 18 and can brake the main drive wheel 18 or the support wheel 13 to ensure that the rail car can achieve emergency braking after the power is cut off. The emergency stop device improves the safety performance of the rail car in emergency situations.

[0046] In some preferred embodiments, in order to improve the energy utilization rate of the system, the above mechanical brake can be provided with a regenerative braking energy recovery device. The regenerative braking energy recovery device includes at least one energy recovery motor 34 and an energy storage unit 35 electrically connected to the motor. When the rail car decelerates or brakes, the energy recovery motor 34 operates as a generator to convert the kinetic energy of the rail car into electrical energy and store it in the energy storage unit 35. The energy storage unit 35 can be but is not limited to a battery pack, a supercapacitor or a flywheel energy storage system. The regenerative braking energy recovery device also includes a control unit for controlling the operating state of the energy recovery motor and managing the storage and use of energy. The control unit can automatically adjust the working mode of the energy recovery motor according to the operating state and energy demand of the rail car to optimize the energy recovery efficiency and the braking performance of the rail car. The specific operation method includes the following steps:

[0047] 1. According to the transport load, design and calculate the required load-bearing components, process the required components in the workshop, and pre-assemble some components while processing to ensure that all parts meet the requirements. Different sizes of track power drive vehicles and travel tracks can be designed according to the load size and transportation needs.

[0048] 2. After the track is installed, the processed driving vehicle parts are assembled on the track according to the designed track vehicle. The track is composed of the track upper flange plate 25, the web plate 26, and the track lower flange plate 12. The track upper flange plate 25 is in direct contact with the driving wheel, providing a rolling interface and a load-bearing support surface for the driving wheel; the web plate 26 supports the track upper flange plate and transfers the load gravity to the track lower flange plate 12. Baffles 10 are welded at both ends of the track lower flange plate 12 to solve the problem of easy deviation of the support wheel during installation and operation, facilitate positioning and installation, and provide auxiliary guarantee for the track vehicle to run along the track.

[0049] 3. The support wheel 13 is assembled with the support keel 9. The support wheel 13 is placed in the inner baffle of the lower flange plate 12 of the track. When working, the support wheel 13 rolls on the interface of the lower flange plate 12, and then the clamping system is installed. The clamping system consists of the longitudinal steel rib plate 7, the roller fixing frame 23, the clamping roller 8, and the locking bolt. The two ends of the longitudinal steel rib plate 7 are fixed to the support keel 9 by locking bolts. The clamping roller 8 is installed on the roller fixing frame 23. When working, the clamping roller rolls closely on the web 26, which effectively prevents the drive system from running off, and can also prevent the drive system from swinging vertically left and right. The roller fixing frame 23 is welded on the longitudinal steel rib plate 7 to provide fixed support for the clamping roller.

[0050] 4. Install one side steel plate 2 on the upper part of the installed supporting keel, install the main driving wheel 18, the main wheel gear 20, the changing gear 27, the slave wheel 16, and the slave wheel gear 6 on the plate side 2, and each wheel axle passes through the hole on the steel plate.

[0051] 5. The motor bracket 5 and the drive motor 4 are installed on the steel plate on the other side. After being aligned with the hollow positions of each wheel axle, they are formally installed on the supporting keel 9 and the rear cover panel 19 is completed.

[0052] 6. Connect the external power cord of the motor, turn on the rotary switch of the controller, and operate the mode button, and the rail car will run normally.

[0053] This rail-driven power vehicle system can not only be installed on the track on the construction ground, but also be used for aerial transfer, transportation and other needs; in addition to the construction industry, it can also be promoted and applied in other industries; it is easy to maintain during use and has strong practicality.

[0054] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
