Description

Technical Field

[0001] The embodiments of the present invention belong to the field of rail vehicle technology, specifically relating to the technical field of driving and operating a monorail rail vehicle. Background Technology

[0002] Currently, monorail vehicles are commonly used in the transportation industry. Typical monorail vehicles rely on rollers to move along the track surface, with the rollers supporting all the load. If the load is too large, the friction during movement will also increase, placing high demands on the drive motor and easily damaging the motor, circuitry, and other equipment. Furthermore, in daily use, issues such as roller slippage on the track surface, deviation during transport, and unstable vertical and lateral swaying are common, and the limited load-bearing capacity hinders their widespread application. Summary of the Invention

[0003] In view of the above-mentioned defects or improvement needs of the existing technology, the present invention aims to solve the problems that existing monorail vehicle drive operation systems are prone to slippage between the rollers and the track surface, deviation during transportation, unstable vertical and horizontal swaying, limited transport load, and easy damage to the motor and circuit.

[0004] To achieve the above objectives, the present invention provides a monorail vehicle drive system, comprising a support system, a drive system, an I-shaped track, and a vertical clamping system;

[0005] The support system includes a support keel, support wheels, a main drive wheel axle, and a lower wheel axle; the support keel is a truss structure set on both sides of the longitudinal direction of the track; there are two support wheels, which are installed on the upper end surface of the lower flange plate of the I-shaped track on both sides of the lower part of the support keel through the lower wheel axle; the main drive wheel axle and the lower wheel axle are rotatably mounted on the support keel;

[0006] The drive system includes a drive unit (e.g., an electric motor, gasoline engine, diesel engine, or steam turbine), a main drive wheel, a main wheel coaxial gear, a driven wheel coaxial gear, a driven wheel axle, and a driven wheel. The drive unit is fixedly mounted on the inner side of the supporting keel. The power output end of the drive unit is fixedly connected to the main drive wheel axle. The main drive wheel and the main wheel coaxial gear are fixedly mounted on the main drive wheel axle. The drive unit drives the main drive wheel to rotate through the main drive wheel axle. At the same time, the main wheel coaxial gear on the main drive wheel axle also synchronously drives the two reversing gears on its left and right sides to rotate. The two reversing gears drive the two driven wheel coaxial gears, and drive the driven wheel to rotate synchronously through the driven wheel axle.

[0007] The track includes an upper flange, a web, and a lower flange; the track as a whole is I-shaped.

[0008] The supporting keel includes vertical plates arranged on both sides of the track in the longitudinal direction, with two vertical plates on each side, and the two vertical plates are connected by a longitudinal frame.

[0009] It also includes lateral reinforcing plates, which are steel plates or alloy plates. There are two lateral reinforcing plates, which are symmetrically fixed (e.g., connected by bolts) on the outer sides of the two supporting keels.

[0010] Furthermore, the top of the supporting keel is provided with a top bolt hole; the bottom of the supporting keel is provided with a suspension keel and a hanging bolt hole, both of which serve as hoisting devices.

[0011] Furthermore, it also includes a protective structure; the protective structure is a protective plate disposed above the main drive wheel, one or both ends of the protective plate being fixedly connected to the supporting keel.

[0012] Furthermore, it also includes an L-shaped bracket; the bracket is connected to the supporting keel, and the drive device is fixedly mounted on the bracket.

[0013] Furthermore, baffles for limiting the position are fixedly provided on the outer side of the upper surface support wheel of the lower flange plate.

[0014] Furthermore, it also includes a remote control system, which comprises a signal transceiver on the drive motor, a controller handle and its signal transceiver, and different buttons on the controller to transmit different signals. The surfaces of the main drive wheel and the driven wheel are also coated with polyurethane material to form wheel sleeves.

[0015] Furthermore, the vertical clamping system includes longitudinal steel ribs, roller fixing frames, clamping rollers, and locking bolts. The two ends of the longitudinal steel ribs are fixed to the supporting keel by locking bolts. The clamping rollers are installed on the roller fixing frames, and the roller surfaces of the clamping rollers abut against the web of the I-shaped track. The roller fixing frames are connected to the longitudinal steel ribs.

[0016] As another aspect of the present invention, a driving operation method for a monorail vehicle driving operation system is also provided, comprising the following steps:

[0017] 1) Based on 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 them to ensure that each component meets the requirements;

[0018] 2) After installing the track, assemble the pre-processed drive vehicle parts on the track according to the designed track vehicle;

[0019] 3) Assemble the support wheel and support keel. Place the support wheel inside the baffle on the inner side of the lower flange plate of the track, and then install the clamping system.

[0020] 4) Install a steel plate on one side of the installed support keel. Install the main drive wheel, main gear, reversing gear, driven wheel, and driven gear on the side of the plate. The axles of each wheel pass through the holes in the steel plate.

[0021] 5) Install the motor bracket and drive motor on the other side of the steel plate. After aligning them with the holes of each wheel axle, install them on the support keel and complete the back cover panel.

[0022] 6) Connect the external power supply to the motor, turn on the power switch of the controller, press the operation mode button, and the railcar will run normally.

[0023] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:

[0024] (1) The monorail vehicle driving system of the present invention, by setting up a main drive wheel, a driven wheel and a support wheel and other multiple support wheel sets, ensures the self-bearing capacity and stability of the driving system, effectively shares the load borne by the main drive wheel, solves the problem of drive wheel axle breakage, and can ensure the smoothness and safety of the power-driven railcar during operation.

[0025] (2) The monorail vehicle drive system of the present invention, by setting two sets of driven wheels, can not only share part of the load of the main drive wheel, but also provide greater driving force, solving the problem of insufficient power of the main drive wheel and poor operation of the track vehicle; by adopting a three-wheel transmission system, a reversing gear is added between the driven wheel and the main drive wheel to realize that the driven wheel and the main drive wheel run in the same direction, and the track vehicle runs more powerfully and stably.

[0026] (3) The monorail vehicle drive system of the present invention effectively solves the problem of vertical left and right swaying of the track vehicle by setting up two rows of clamping rollers, thus ensuring the smooth operation of the track vehicle.

[0027] (4) The monorail vehicle drive system of the present invention solves the problem of easy deviation of the support wheel during installation and operation by setting baffles at both ends of the lower flange plate of the track, which facilitates convenient positioning and installation, and provides auxiliary protection for the track vehicle to run along the track.

[0028] (5) The monorail vehicle drive system of the present invention adds a suspension keel and suspension bolt holes under the keel, which facilitates suspension transportation when transported in the air according to actual use needs.

[0029] (6) The monorail vehicle drive system of the present invention increases the friction coefficient between the wheel surface and the track surface by coating the main drive wheel and the driven wheel with a polyurethane material layer, which effectively solves the problem of drive wheel slippage.

[0030] (7) The monorail vehicle driving system of the present invention controls the track vehicle through a wireless controller handle. The power switch of the remote control handle is changed from the conventional button type to an arrow rotation type to prevent accidental presses during operation, avoid safety problems, and is convenient to operate, easy to use, and highly applicable.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0038] To address the limitations of monorail vehicles in terms of load capacity, roller slippage, and unstable vertical and lateral swaying during use, and to expand their application scenarios, this embodiment presents a monorail vehicle drive system. This system effectively enhances the monorail vehicle's load-bearing capacity, ensuring smooth and safe operation. The dimensions of the monorail vehicle can be adjusted and assembled according to the width and height of the track. It can be used not only on construction sites but also for aerial transport needs, making it easy to promote and apply.

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

[0040] Please refer to Figures 1-2 The power drive system includes bolts 3, brackets 5, drive motors 4, main drive wheel 18, main wheel coaxial gear 20, driven wheel 16, driven wheel coaxial gear 6, and a wheel sleeve formed by a polyurethane material coating. The motor can be selected to meet the power requirements according to the load to be borne. The motor 4 is installed and fixed on the support keel 9 by bolts 3 and brackets 5. The motor 4 drives the main drive wheel 18 to rotate and move. At the same time, the main wheel coaxial gear 20 also rotates synchronously, driving the reversing gear 27 to rotate in the opposite direction. The reversing gear 27 drives the driven wheel coaxial gear 6 to change direction, realizing the synchronous rotation of the driven wheel 16 and effectively distributing the load borne by the main drive wheel 18. The surfaces of the main drive wheel 18 and the driven wheel 16 are coated with polyurethane material or polyoxymethylene material to increase the friction between them and the track surface and prevent them from slipping.

[0041] The running track includes an upper flange plate 25, a web plate 26, and a lower flange plate 12. The upper flange plate 25 directly contacts the drive wheel, providing a rolling interface and load-bearing support surface for the drive wheel. The web plate 26 supports the upper flange plate 25 and transfers the load to the lower flange plate 12. The rollers 8 of the vertical clamping system act on the web plate 26. The lower flange plate 12 bears the weight of the support wheel 13, thereby reducing the load on the main drive wheel 18 and preventing excessive main drive load, which could lead to shaft breakage, slippage, and electrical circuit burnout. Baffles 10 are welded to both ends of the lower flange plate 12 to prevent the support wheel 13 from slipping out.

[0042] The support system includes a support keel 9, support wheels 13, wheel axles 24, bolt holes 11, a panel 19, and side steel plates 2. The support wheels 13 are installed on the lower inner side of the support keel 9 via wheel axles 24 and bear part of the upper load. During operation, the support wheels 13 roll on the interface of the lower flange plate 12. The end baffles 10 on both sides of the lower flange plate 12 can help prevent deviation. The bolt holes 11 are for easy suspension and handling during the installation of the drive system. The panel 19 is installed on the upper part of the drive power unit and has a safety protection function. Fastening components for load objects can be placed, installed, or welded on it as needed. It can also effectively prevent debris and pollution from entering and affecting the drive wheels. The side steel plates 2 are fixed to the support keel 9 by bolts 3. The main drive wheel 18, the reversing gear 27, and the coaxial gear 6 of the driven wheel are fixed to the side steel plates 2 at both ends.

[0043] Please refer to Figure 3The vertical clamping system includes longitudinal steel ribs 7, roller fixing frames 23, clamping rollers 8, and locking holes 28. The two ends of the longitudinal steel ribs 7 are fixed to the supporting keel 9 through the locking holes 28. The clamping rollers 8 are installed on the roller fixing frames 23. During operation, the clamping rollers 8 roll close to the web plate 26, effectively preventing the drive system from deviating and preventing the drive system from swinging vertically left and right. The roller fixing frames 23 are welded to the longitudinal steel ribs 7 to provide fixed support for the clamping rollers 8.

[0044] Please refer to Figure 4 The remote control system consists of a signal transmitter 21 on the drive motor 4, a controller handle and a signal transmitter 33 on it; the controller handle is equipped with a forward button 29, a stop button 30, a reverse button 31 and a power-on rotary switch 32. By operating the buttons on the controller handle, the railcar can be operated.

[0045] In some preferred embodiments, to enhance system safety, a fault detection device for the monorail vehicle is also included. This device comprises 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 unit 4, support wheels 13, and electrical wiring. 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 analyzes the sensor data to assess the operating status of the monorail vehicle in real time. Once abnormal data is detected, such as overheating, abnormal vibration, position deviation, or abnormal current, the control unit will trigger a warning signal and take corresponding safety measures according to the fault type, such as deceleration, stopping, or emergency braking. Furthermore, 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 operational safety and reliability of the monorail 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 located in a position easily accessible to the operator, such as on an operating panel or remote control device. When the operator activates the emergency stop switch, the control unit immediately cuts off the power supply to the drive motor, causing the monorail vehicle to stop quickly and safely. In addition, the control unit is equipped with an emergency braking mechanism, such as a mechanical brake or an electromagnetic brake. The mechanical or electromagnetic brake is mounted on the main drive wheel 18 and can brake either the main drive wheel 18 or the support wheel 13 to ensure that the railcar can achieve emergency braking after power is cut off. This emergency stop device improves the safety performance of the railcar in emergency situations.

[0046] In some preferred embodiments, to improve the system's energy utilization rate, the mechanical brake can be equipped 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 railcar decelerates or brakes, the energy recovery motor 34 operates as a generator, converting the railcar's kinetic energy into electrical energy and storing 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 energy storage and use. The control unit can automatically adjust the operating mode of the energy recovery motor according to the railcar's operating state and energy demand to optimize energy recovery efficiency and the railcar's braking performance. The specific operation method includes the following steps:

[0047] 1. Based on the transport load, design and calculate the required load-bearing components, and process each component in the workshop. Some components are pre-assembled while being processed to ensure that all parts meet the requirements. Different sizes of track-driven vehicles and tracks can be designed according to the load size and transportation needs.

[0048] 2. After installing the track, assemble the pre-fabricated drive vehicle components onto the track according to the designed track vehicle. The track consists of an upper flange plate 25, a web plate 26, and a lower flange plate 12. The upper flange plate 25 directly contacts the drive wheels, providing a rolling interface and load-bearing support surface for the drive wheels. The web plate 26 supports the upper flange plate and transfers the load to the lower flange plate 12. Baffles 10 are welded to both ends of the lower flange plate 12 to solve the problem of the support wheels easily running off-center during installation and operation, facilitate positioning and installation, and provide auxiliary protection 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 inside the baffle of the lower flange plate 12 of the track. During operation, the support wheel 13 rolls on the interface of the lower flange plate 12. Then, the clamping system is installed. The clamping system consists of longitudinal steel ribs 7, roller fixing frame 23, clamping rollers 8, and locking bolts. The two ends of the longitudinal steel ribs 7 are fixed to the support keel 9 by locking bolts. The clamping rollers 8 are installed on the roller fixing frame 23. During operation, the clamping rollers roll close to the web plate 26, effectively preventing the drive system from deviating and preventing the drive system from swinging vertically left and right. The roller fixing frame 23 is welded to the longitudinal steel ribs 7 to provide fixed support for the clamping rollers.

[0050] 4. Install a steel plate 2 on the upper part of the installed support keel. Install the main drive wheel 18, main wheel gear 20, reversing gear 27, driven wheel 16, and driven wheel gear 6 on the side of the plate 2. The axles of each wheel pass through the holes in the steel plate.

[0051] 5. Install the motor bracket 5 and drive motor 4 on the other side steel plate. After aligning them with the positions of the holes in each wheel axle, install them on the support keel 9. The upper panel 19 of the rear cover is then completed.

[0052] 6. Connect the external power supply to the motor, turn on the controller, turn on the rotary switch, press the operation mode button, and the railcar will run normally.

[0053] This rail-driven vehicle system can be used not only on construction sites with rails installed, but also for aerial transfer and transportation. In addition to the construction industry, it can also be promoted and applied in other industries. It is easy to maintain and highly practical.

[0054] Those skilled in the art will readily understand that the above description is merely 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 within the scope of protection of the present invention.
