Description
Technical Field
[0001] This invention relates to the field of rail transport machines, and more particularly to a rail transport machine level monitoring and automatic leveling system. Background Technology
[0002] Agricultural mountain rail transport vehicles are specialized transportation facilities used in agricultural production. They are primarily used for transporting agricultural products, machinery, supplies, and personnel (workers, farmers, etc.) in mountainous farms, orchards, and fields. Their main functions include: 1. Improving agricultural production efficiency. Agricultural mountain rail transport vehicles can quickly and safely transport agricultural products from harvesting points such as fields or orchards to centralized processing or sales locations, avoiding the problems of inconvenient mountain roads and traffic congestion, thus improving agricultural production efficiency. 2. Reducing agricultural product loss rates. During transportation, agricultural products are often susceptible to damage from bumps and impacts, leading to losses. Using agricultural mountain rail transport vehicles can reduce vibration and impact during transportation, ensuring the safety of transported goods and reducing the damage rate. 3. Improving farmers' labor efficiency. Agricultural mountain rail transport vehicles can quickly and conveniently transport farmers, workers, and machinery, greatly reducing the transportation burden on farmers, improving their labor efficiency, and reducing the rate of work-related injuries. 4. Environmental protection and energy conservation. Compared to fuel-powered vehicles, agricultural mountain rail transport vehicles are powered by electricity, which is more environmentally friendly, reduces exhaust pollution and energy consumption, and helps protect the environment.
[0003] Currently, agricultural products and supplies are mainly transported manually, by vehicles, monorail conveyors, and double-rail conveyors. Manual transport is a common method in traditional agricultural production, but it is inefficient, prone to manpower shortages and high labor intensity, and has limitations in terms of the amount and distance of goods that can be transported. It is also highly susceptible to weather conditions. Vehicle transport can quickly and conveniently transport large quantities of agricultural products or supplies, but it faces numerous problems in rugged terrain such as mountainous areas, including narrow roads, steep slopes, slippery surfaces, and a high risk of accidents. Furthermore, vibrations and bumps during transport can easily lead to breakage of goods, and the cost is high. Monorail conveyors are devices that transport agricultural products and supplies via rails. Installed at elevated locations, they are suitable for rugged environments such as mountainous areas. Double-rail conveyors are similar to monorail conveyors, but with two parallel tracks, significantly increasing transport capacity and making them suitable for long-distance transport of large quantities of goods and supplies. However, the stability of current monorail and double-rail transport vehicles is relatively poor. For example, monorail vehicles are prone to overturning when turning or when the load on both sides is uneven. When double-rail vehicles go up or down slopes, the items inside the vehicles are very easy to scatter. Summary of the Invention
[0004] To address the aforementioned problems, the present invention aims to provide a leveling and automatic leveling system for a rail transport vehicle. This system adds auxiliary rails to both sides of the monorail to prevent the transport vehicle from swaying left and right. It adjusts the tilt angle of the transport vehicle by detecting the slope to ensure it remains level, preventing cargo from falling off. A feedback adjustment device keeps the transport vehicle running at a set speed, and an electromagnetic braking system is used to brake the vehicle. This method prevents the transport vehicle from swaying left and right, thus avoiding tipping over, preventing cargo from falling off, maintaining a constant speed, and enabling emergency braking in unexpected situations. It improves the safety, efficiency, and quality of the transport vehicle, has scalability, and is expected to align with the development trend of modern intelligent manufacturing, demonstrating excellent application prospects and market demand.
[0005] To achieve the above objectives, the present invention provides a rail transport machine level monitoring and automatic leveling system as follows:
[0006] A rail transport machine level monitoring and automatic leveling system includes a transport machine, auxiliary rails, a support frame, a support column, and a track. The support frame is fixed on the support column, and the track is installed on the support frame. The support frame is U-shaped, and two auxiliary rails are installed at both ends of the support frame. The transport machine runs on the track, and the auxiliary rails maintain the balance of the left and right ends of the transport machine. During the transport of goods, the transport machine can automatically detect its own tilt angle. When the tilt angle deviates, it can automatically adjust the horizontal position of the transport machine's cargo box to keep the cargo box in a horizontal state, thus achieving the purpose of automatic leveling. The system can also adjust the operating speed of the transport machine by detecting its speed, so that the transport machine runs at a set speed. An electromagnetic braking device is used to brake the transport machine to prevent the goods from falling off and can provide emergency braking in case of emergencies.
[0007] The support frame of the present invention includes a crossbar and two uprights. The crossbar is mounted on the support column, and two uprights are fixed at both ends of the crossbar. Each upright supports an auxiliary rail. Two self-stabilizers are installed between the transport machine and the two auxiliary rails to prevent the transport vehicle from swaying from side to side.
[0008] The track of the present invention includes a groove and a rack. The track is forged from carbon steel. The middle of the track is set as a groove and the right side is set as a rack. The groove is used to provide guidance for the operation of the transport machine. The rack meshes with the gear of the transport vehicle to provide the transmission basis for the transport machine and also plays a guiding role.
[0009] The transport vehicle of this invention includes a head unit, a fuel tank, a generator, a controller, a motor speed controller, a motor, a speed sensor, a transmission, a gearbox, first casters, a first tilt sensor, hydraulic jacks, an electromagnetic brake device, second casters, a frame, a cargo box, a second tilt sensor, a first displacement sensor, and a second displacement sensor. The head unit and cargo box are mounted on the frame. First and second casters are respectively located below the frame. The fuel tank, generator, controller, motor speed controller, motor, speed sensor, gearbox, and first tilt sensor are all installed in the head unit. The fuel tank provides gasoline to the generator, which converts the gasoline into electrical energy to power the motor. The controller is electrically connected to the motor speed controller, and the motor speed controller is electrically connected to the motor. The controller controls the output of the motor speed controller, thereby controlling the speed of the motor. The motor shaft is connected to the gearbox, and the output end of the gearbox is connected to the transmission. The motor drives the gearbox, and the gearbox drives the transmission, causing the transmission to move the transport vehicle on the track. Two hydraulic jacks are used. Installed between the cargo box and the frame, it is used to adjust the height of the cargo box. The electromagnetic brake device is installed at the bottom of the frame for braking the transport machine. The first displacement sensor and the second displacement sensor are respectively installed at the bottom of both ends of the cargo box to detect the distance between the two ends of the cargo box and the frame, so that the controller can adjust the extension and retraction of the hydraulic top, thereby adjusting the cargo box to the same horizontal plane. The second tilt sensor is installed at the top of the cargo box to detect the tilt angle of the cargo box. The first tilt sensor is used to detect the tilt angle of the machine head. The first tilt sensor and the second tilt sensor transmit the collected information to the controller, which controls the hydraulic top to adjust the front and rear height of the cargo box to keep the cargo box at the same horizontal plane and prevent the goods from falling. The speed sensor is used to detect the running speed of the transport machine and transmits the collected speed information to the controller. The controller then controls the motor speed regulator to adjust the speed of the motor, thereby realizing the feedback regulation of the transport machine speed and keeping the transport machine traveling at the preset speed. The two second iron casters under the cargo box and the first iron caster under the machine head move in the grooves of the track.
[0010] The transmission device of the present invention includes a transmission shaft and gears. After the electric motor drives the transmission shaft to rotate, it drives the gears to rotate. After the gears mesh with the rack, the transport machine can be driven to travel on the track.
[0011] The first and second iron casters of this invention are connected to the vehicle frame by shock absorbers.
[0012] The electromagnetic braking device of this invention includes a spring, a relay, an electromagnet, and an iron block. Two springs connect the iron block to the bottom of the frame, with the iron block positioned above the track. The relay and electromagnet are mounted at the bottom of the frame. The control terminal of the relay is connected to a controller, the normally open terminal of the relay is connected to the power output of the generator, and the common terminal of the relay is connected to the electromagnet. The controller controls the on / off state of the relay, thereby controlling the operation of the electromagnet. When braking is not required, the controller controls the relay to open, energizing the electromagnet and generating a magnetic field, which attracts the iron block, causing it to leave the track. When braking is required, the controller stops the motor, and the gears and rack engage to brake the transport mechanism. At this time, the controller controls the relay to close, disconnecting the power to the electromagnet. Under the action of the springs, the iron block is pushed onto the track, utilizing the friction between the iron block and the track to achieve secondary braking.
[0013] The self-stabilizer of this invention includes hydraulic shock absorbers, a third caster, a slider, and a telescopic motor. Self-stabilizers are installed on the left and right sides of the cargo box. The bottom of the telescopic motor is fixed to the frame, and the telescopic rod of the motor is connected to the slider. The third caster is connected to the slider via hydraulic shock absorbers, which push the third caster into the groove of the auxiliary rail. When the cargo box shifts to the left or right due to uneven force, the hydraulic shock absorbers push the cargo box back to left-right balance. When the transport vehicle is moving, the third caster moves within the groove of the auxiliary rail. When the front or rear end of the cargo box is hydraulically lifted, the controller controls the telescopic motor to pull the slider down, keeping the third caster and the auxiliary rail at the same level, preventing the self-stabilizer from breaking due to the tilt of the cargo box.
[0014] The automatic leveling scheme for the transport vehicle in this invention is as follows: When the transport vehicle encounters a downhill section, the tilt angle of the leading front end changes. A first tilt angle sensor collects this change information and transmits it to the controller. The controller then controls the output of the motor speed controller, thereby controlling the motor speed to prevent the transport vehicle from overspeeding and tipping over. Immediately afterwards, a second tilt angle sensor transmits its collected information to the controller. Because the front of the cargo box is lower than the rear when the transport vehicle is going downhill, the controller raises the hydraulic jack at the bottom of the front of the cargo box. The second tilt angle sensor continuously collects the tilt angle of the cargo box. Only after the cargo box is level does the controller stop the hydraulic jacks. When the second tilt sensor detects that the front of the cargo box is higher than the rear, the controller retracts the hydraulic jacks at the bottom of the front of the cargo box to lower the front height and bring the front and rear of the cargo box to the same level. As the front of the cargo box rises, the first displacement sensor constantly monitors the distance between the front of the cargo box and the frame. Based on the displacement information from the first displacement sensor, the controller controls the telescopic motors on both sides of the cargo box to retract, pulling the stabilizer down. When the hydraulic jacks at the bottom of the front of the cargo box retract, the controller controls the telescopic motors to extend, pulling the stabilizer down. The stabilizer moves upwards, ensuring it remains level with the auxiliary rail. When the transport vehicle encounters an uphill section, the tilt angle of the leading front end changes. This change is collected by the first tilt sensor and transmitted to the controller. The controller then adjusts the output of the motor speed controller, increasing the motor speed to maintain a consistent speed as the transport vehicle climbs. Next, the second tilt sensor transmits its collected information to the controller. Because the front of the cargo box is higher than the rear when the transport vehicle goes uphill, the controller raises the hydraulic jack at the rear of the cargo box. The second tilt sensor continuously collects data... The tilt angle of the cargo box is adjusted until the cargo box is level. Only then does the controller stop the hydraulic jack. As the front of the cargo box rises, the second displacement sensor constantly monitors the distance between the rear of the cargo box and the frame. Based on the displacement information from the second displacement sensor, the controller controls the telescopic motors on both sides of the cargo box to retract, pulling the stabilizer down. When the hydraulic jack at the bottom of the rear of the cargo box retracts, the controller controls the telescopic motor to extend, moving the stabilizer upward so that the stabilizer always remains at the same level as the auxiliary rail. When the transport vehicle is traveling on a level road, the controller does not need to adjust the hydraulic jack and telescopic motor.
[0015] Because this invention uses a second tilt sensor to detect the tilt angle of the cargo box and then adjusts the height of the cargo box from front to back, the following beneficial effects can be achieved:
[0016] 1. This invention adds auxiliary rails to both sides of the monorail transporter to prevent the transport vehicle from swaying left and right during operation, thus avoiding the risk of goods falling off. Furthermore, by adjusting the tilt angle of the carriage, the transport vehicle can be kept level, improving transport safety.
[0017] 2. This invention employs a dual braking system, which can improve the braking effect of the transport vehicle on steep slopes, reduce braking distance, increase overall safety, ensure the safety of the transport vehicle, and prevent accidents. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the embodiments and the accompanying drawings.
[0031] Please see Figures 1 to 10The figure shows a track transport machine level monitoring and automatic leveling system according to the present invention, including a transport machine 1, an auxiliary rail 2, a support 3, a support column 4, and a track 5.
[0032] like Figure 1 As shown, the support 3 is fixed on the pillar 4, and the track 5 is installed on the support 3. The support 3 is a U-shaped support 3, and two auxiliary rails 2 are installed at both ends of the support 3. The transport machine 1 runs on the track 5. The auxiliary rails 2 are used to maintain the balance of the left and right ends of the transport machine 1. This method can prevent the transport machine 1 from swaying left and right and causing it to tip over. During the transportation of goods, the transport machine 1 can automatically detect its own tilt angle. When the tilt angle deviates, it can automatically adjust the horizontal position of the cargo box 26 of the transport machine 1 so that the cargo box 26 of the transport machine 1 is always in a horizontal state, achieving the purpose of automatic leveling to prevent the transported goods from falling. The speed of the transport machine 1 is detected to adjust its running speed so that the transport machine 1 runs at the set speed. An electromagnetic brake device 23 is used to brake the transport machine 1 to prevent the goods from falling. It can brake in case of emergencies, which improves the safety, efficiency and quality of the transport machine 1. It has scalability and is expected to meet the development trend of modern intelligent manufacturing. It has good application prospects and market demand.
[0033] like Figure 2 As shown, the support frame 3 includes a crossbar 6 and two uprights 7. The crossbar 6 is mounted on the support column 4, and two uprights 7 are fixed to both ends of the crossbar 6. Each upright 7 supports an auxiliary rail 2. Two self-stabilizers 8 are installed between the transport vehicle 1 and the two auxiliary rails 2 to prevent the transport vehicle from swaying left and right. By installing uprights 7 and auxiliary rails 2 at both ends of the crossbar 6, the stability of the entire support frame 3 can be effectively increased. The support column 4 provides support and transfers the weight of the transport vehicle 1 to the ground, making the transport vehicle 1 run more smoothly. At the same time, the use of self-stabilizers 8 can further improve the stability of the transport vehicle and prevent swaying left and right.
[0034] like Figure 3 , Figure 5 As shown, the track 5 includes a groove 9 and a rack 10. The track 5 is forged from carbon steel. The groove 9 is set in the middle of the track 5, and the rack 10 is set on the right side. The groove 9 is used to provide guidance for the operation of the transport vehicle 1. The rack 10 meshes with the gear 31 of the transport vehicle, providing the transmission basis for the transport vehicle 1, and also playing a guiding role to ensure that the transport vehicle travels along the predetermined direction of the track 5 and prevents lateral deviation or deviation. Moreover, the rotation of the gear 31 can drive the transport vehicle to push or brake. The rack 10 transmission enables the vehicle to run on the track 5, control speed and acceleration / deceleration, and meet specific transportation needs.
[0035] like Figure 4As shown, the transport machine 1 includes a head unit 11, a fuel tank 12, a generator 13, a controller 14, a motor speed regulator 15, a motor 16, a speed sensor 17, a transmission 18, a gearbox 19, first casters 20, a first tilt sensor 21, a hydraulic jack 22, an electromagnetic brake device 23, second casters 24, a frame 25, a cargo box 26, a second tilt sensor 27, a first displacement sensor 28, and a second displacement sensor 29. The head unit 11 and the cargo box 26 are mounted on the frame 25. The first caster 20 and the second caster 24 are respectively located under the frame 25. The fuel tank 12, generator 13, controller 14, and motor speed regulator 15 are also included. The motor 16, speed sensor 17, gearbox 19, and first tilt sensor 21 are all installed in the engine head 11. The fuel tank 12 supplies gasoline to the generator 13, which converts the gasoline into electrical energy to power the motor 16. The controller 14 is electrically connected to the motor speed controller 15, which in turn is electrically connected to the motor 16. The controller 14 controls the output of the motor speed controller 15, thereby controlling the speed of the motor 16. The shaft of the motor 16 is connected to the gearbox 19, and the output of the gearbox 19 is connected to the transmission 18. The motor 16 drives the gearbox 19, which in turn drives the transmission 18, causing the transmission 18 to... The conveyor 1 is driven to move on track 5. Two hydraulic jacks 22 are installed between the cargo box 26 and the frame 25 to adjust the height of the cargo box. An electromagnetic brake device 23 is installed at the bottom of the frame 25 for braking the conveyor 1. A first displacement sensor 28 and a second displacement sensor 29 are respectively installed at the bottom of both ends of the cargo box 26 to detect the distance between the two ends of the cargo box 26 and the frame 25, so that the controller 14 can adjust the extension and retraction of the hydraulic jacks 22 to adjust the cargo box 26 to the same horizontal plane. A second tilt sensor 27 is installed at the top of the cargo box 26 to detect the tilt angle of the cargo box 26. A first tilt sensor 21 is used to detect the tilt angle of the machine head 11. A tilt sensor 21 and a second tilt sensor 27 transmit the collected information to a controller 14. The controller 14 then controls a hydraulic jack 22 to adjust the front and rear height of the cargo box 26, ensuring that the cargo box 26 is on the same horizontal plane and preventing goods from falling. A speed sensor 17 detects the operating speed of the transport machine 1 and transmits the collected speed information to the controller 14. The controller 14 then controls a motor speed regulator 15 to adjust the speed of the motor 16, thereby achieving feedback adjustment of the transport machine 1's speed and maintaining the preset speed. The two second casters 24 under the cargo box 26 and the first caster 20 under the machine head 11 move in the grooves 9 of the track 5. By collecting the speed and tilt information of the transport machine 1 and adjusting the motor 16 and hydraulic jack 22 through the controller 14, the stability of the transport machine 1 during operation is maintained. With the feedback signal from the speed sensor 17, the transport machine 1 can respond and adjust in a timely manner to ensure that the cargo box 26 is on the same horizontal plane and to prevent goods from falling.
[0036] like Figure 5 As shown, the transmission device 18 includes a transmission shaft 30 and a gear 31. After the electric motor 16 drives the transmission 19, it drives the transmission shaft 30 to rotate, which in turn drives the gear 31 to rotate. After the gear 31 meshes with the rack 10, it can drive the transport machine 1 to travel on the track 5.
[0037] like Figure 6 As shown, the first caster wheel 20, the second caster wheel 24, and the frame 25 are connected by shock absorbers 32. The shock absorbers 32 can absorb and reduce the vibration and impact of the transport vehicle 1 during operation, thereby reducing the collision of agricultural products during transportation. The connection between the caster wheel and the frame 25 is buffered and the transmission of vibration is reduced through the shock absorbers 32, effectively reducing the vibration level of the transport vehicle 1.
[0038] like Figure 7 As shown, the electromagnetic braking device 23 includes a spring 33, a relay 34, an electromagnet 35, and an iron block 36. Two springs 33 connect the iron block 36 to the bottom of the frame 25, with the iron block 36 positioned above the track 5. The relay 34 and electromagnet 35 are mounted at the bottom of the frame 25. The control terminal of the relay 34 is connected to the controller 14, the normally open terminal of the relay 34 is connected to the power output of the generator 13, and the common terminal of the relay 34 is connected to the electromagnet 35. The controller 14 controls the on / off state of the relay 34, thereby controlling the operation of the electromagnet 35. When braking is not required, the controller 14 controls the relay 34 to open, causing the electromagnet 35 to operate. The charged iron block 35 generates a magnetic field, which attracts the iron block 36, causing it to leave the track 5. When braking is needed, the controller 14 stops the motor, and the gear 31 engages with the rack 10 to brake the transport machine 1. At this time, the controller 14 controls the relay 34 to turn off, disconnecting the power supply to the electromagnet 35. Under the action of the spring 33, the iron block 36 is pushed onto the track 5, using the friction between the iron block 36 and the track 5 to achieve secondary braking. When braking is not needed, the charged electromagnet 35 generates a magnetic field to attract the iron block 36, causing it to leave the track 5, thus reducing energy loss caused by friction. Only when braking is needed will the power supply to the electromagnet 35 be disconnected, initiating secondary braking to provide appropriate braking force. By using two braking methods, the braking effect of the transport machine 1 on steep slopes can be improved, the braking distance reduced, and the overall safety increased.
[0039] like Figure 8As shown, the self-stabilizer 8 includes a hydraulic shock absorber 37, a third caster 38, a slider 39, and a telescopic motor 40. Self-stabilizers 8 are installed on the left and right sides of the cargo box 26. The bottom of the telescopic motor 40 is fixed to the frame 25. The telescopic rod of the telescopic motor 40 is connected to the slider 39. The third caster 38 is connected to the slider 39 through the hydraulic shock absorber 37. The hydraulic shock absorber 37 pushes the third caster 38 into the groove of the auxiliary rail 2. When the cargo box shifts to the left or right due to uneven force, the hydraulic shock absorber 37 pushes the cargo box back to left and right balance. When the transport vehicle is moving, the third caster 38 moves in the groove of the auxiliary rail 2. When the front or rear end of the cargo box 26 is lifted by the hydraulic jack 22, the controller 14 will control the telescopic motor 40 to pull the slider 39 down, so that the third caster 38 and the auxiliary rail 2 are on the same horizontal plane, preventing the self-stabilizer 8 from being broken due to the tilt of the cargo box 26. The combination of hydraulic shock absorber 37, third caster 38, slider 39, and telescopic motor 40 achieves automatic balancing and stabilization of cargo box 26. When cargo box 26 is subjected to uneven forces, the self-stabilizer 8 can adjust in time to bring cargo box 26 back to a balanced state, thus maintaining stable transportation.
[0040] like Figure 9As shown, the automatic leveling scheme of the conveyor 1 in this invention is as follows: When the conveyor 1 encounters a downhill section, the tilt angle of the leading head 11 changes. The first tilt angle sensor 21 collects this change information and transmits it to the controller 14. The controller 14 then controls the output of the motor speed controller 15, thereby controlling the speed of the motor 16 to prevent the conveyor 1 from overturning due to excessive speed. Next, the second tilt angle sensor 27 transmits the collected information to the controller 14. Because the front of the cargo box 26 is lower than the rear when the conveyor 1 goes downhill, the controller 14 controls the hydraulic jack 22 at the bottom of the front of the cargo box 26 to rise. The second tilt angle sensor 27 continuously collects the tilt angle of the cargo box 26 until the tilt angle is adjusted. After the cargo box 26 is level, the controller 14 stops the hydraulic top 22 from working. When the second tilt sensor 27 detects that the front end of the cargo box 26 is higher than the rear end, the controller 14 controls the hydraulic top 22 at the bottom of the front end of the cargo box 26 to retract, thereby lowering the height of the front end of the cargo box 26 and bringing the front and rear ends of the cargo box 26 to the same level. As the front end of the cargo box 26 rises, the first displacement sensor 28 constantly detects the distance between the front end of the cargo box 26 and the frame 25. Based on the displacement information transmitted by the first displacement sensor 28, the controller 14 controls the telescopic motors 40 on both sides of the cargo box 26 to retract, pulling down the stabilizer 8. When the hydraulic top 22 at the bottom of the front end of the cargo box 26 retracts, the controller 14 controls the telescopic motors 40 to extend. The stabilizer 8 is moved upwards to keep it level with the auxiliary rail 2. When the transport vehicle 1 encounters an uphill section, the tilt angle of the leading head 11 changes. The first tilt sensor 21 collects this information and transmits it to the controller 14. The controller 14 then controls the output of the motor speed controller 15, thereby increasing the speed of the motor 16 to keep the transport vehicle climbing at the same speed. Next, the second tilt sensor 27 transmits its collected information to the controller 14. Because the front of the cargo box 26 is higher than the rear when the transport vehicle 1 goes uphill, the controller 14 controls the hydraulic jack 22 at the rear bottom of the cargo box 26 to rise. The second tilt sensor 27 continuously collects the information from the cargo box 26. The tilt angle is set to 6. Once the cargo box 26 is level, the controller 14 stops the hydraulic jack 22. As the front of the cargo box 26 rises, the second displacement sensor 29 constantly monitors the distance between the rear of the cargo box 26 and the frame 25. Based on the displacement information from the second displacement sensor 29, the controller 14 controls the telescopic motors 40 on both sides of the cargo box 26 to retract, pulling the stabilizer 8 downwards. When the hydraulic jack 22 at the bottom of the rear of the cargo box 26 retracts, the controller 14 controls the telescopic motors 40 to extend, moving the stabilizer 8 upwards, ensuring that the stabilizer 8 remains level with the auxiliary rail 2. When the transport vehicle 1 is traveling on a level road, the controller 14 does not need to adjust the hydraulic jack 22 and the telescopic motors 40. The transport vehicle speed and the levelness of the cargo box 26 are adjusted by using the tilt angle information detected by the first tilt angle sensor 21 and the second tilt angle sensor 27 to maintain the cargo box 26 in a balanced state.This helps prevent transport vehicle 1 from overturning or becoming unbalanced on downhill or uphill sections. The automatic leveling system allows the transport vehicle to maintain a constant speed when climbing uphill, avoiding excessively slow speeds or stagnation, thus improving transport efficiency. Simultaneously, automatic leveling reduces reliance on operators, increasing the automation level of transport vehicle 1.
[0041] The working principle and process of this invention are as follows:
[0042] like Figure 10As shown, the speed sensor 17 detects the operating speed of the transport machine 1 and transmits the collected speed information to the controller 14. The controller 14 then controls the motor speed regulator 15 to adjust the speed of the motor 16, thereby realizing the feedback regulation of the transport machine 1's speed and keeping the transport machine 1 traveling at a preset speed. The controller 14 controls the on / off state of the relay 34, which in turn controls the operation of the electromagnet 35. When braking is not required, the controller 14 controls the relay 34 to open, so that the electromagnet 35 is energized and generates a magnetic field, which attracts the iron block 36 and makes the iron block 36 leave the track 5. When braking is required, the controller 14 controls the motor to stop rotating, and the gear 31 engages with the rack 10 to brake the transport machine 1. At this time, the controller 14 controls the relay 34 to close, so that the electromagnet... When the power supply to 35 is disconnected, the iron block 36, under the action of spring 33, pushes itself onto track 5, using the friction between the iron block 36 and track 5 to achieve secondary braking. When the transport machine 1 encounters a downhill section, the tilt angle of the leading head 11 changes. The first tilt angle sensor 21 collects this change information and transmits it to the controller 14. The controller 14 then controls the output of the motor speed controller 15, thereby controlling the speed of the motor 16 to prevent the transport machine 1 from overspeeding and tipping over. Next, the second tilt angle sensor 27 transmits the collected information to the controller 14. Because the front of the cargo box 26 is lower than the rear when the transport machine 1 goes downhill, the controller 14 controls the hydraulic jack 22 at the bottom of the front of the cargo box 26 to rise. The second tilt angle sensor... The second tilt sensor 27 continuously collects the tilt angle of the cargo box 26 until the cargo box 26 is on a horizontal plane. Only then does the controller 14 control the hydraulic top 22 to stop working. When the second tilt sensor 27 detects that the front end of the cargo box 26 is higher than the rear end, the controller 14 controls the hydraulic top 22 at the bottom of the front end of the cargo box 26 to retract, thereby reducing the height of the front end of the cargo box 26 and bringing the front and rear ends of the cargo box 26 to the same horizontal plane. As the front end of the cargo box 26 rises, the first displacement sensor 28 constantly detects the distance between the front end of the cargo box 26 and the frame 25. Based on the displacement information transmitted by the first displacement sensor 28, the controller 14 controls the telescopic motors 40 on both sides of the cargo box 26 to retract, pulling down the self-stabilizer 8. When the hydraulic top 22 at the bottom of the front end of the cargo box 26 retracts, the controller 14 controls the telescopic motors 40 to extend. Zhang moves the self-stabilizer 8 upwards, ensuring it remains level with the auxiliary rail 2. When the transport vehicle 1 encounters an uphill section, the tilt angle of the leading head 11 changes. This change is collected by the first tilt sensor 21 and transmitted to the controller 14. The controller 14 then controls the output of the motor speed controller 15, increasing the speed of the motor 16 to maintain a constant speed as the transport vehicle climbs. Next, the second tilt sensor 27 transmits its collected information to the controller 14. As the transport vehicle 1 climbs the slope, the front of the cargo box 26 becomes higher than its rear. The controller 14 then raises the hydraulic jack 22 at the rear bottom of the cargo box 26. The second tilt sensor 27 continuously collects the tilt angle of the cargo box 26 until it is level.Controller 14 stops the hydraulic top 22 from working. As the front of the cargo box 26 rises, the second displacement sensor 29 constantly monitors the distance between the rear of the cargo box 26 and the frame 25. Based on the displacement information from the second displacement sensor 29, controller 14 controls the telescopic motors 40 on both sides of the cargo box 26 to retract, pulling the stabilizer 8 downwards. When the hydraulic top 22 at the bottom of the rear of the cargo box 26 retracts, controller 14 controls the telescopic motors 40 to extend, moving the stabilizer 8 upwards, ensuring that the stabilizer 8 remains at the same horizontal plane as the auxiliary rail 2. When the transport vehicle 1 is traveling on a level road, controller 14 does not need to adjust the hydraulic top 22 and the telescopic motors 40.
Claims
1. A leveling and automatic leveling system for a rail transport vehicle, characterized in that: The system includes a transport aircraft, auxiliary rails, a support frame, a support column, and a track. The support frame is fixed to the support column, and the track is installed on the support frame. The support frame is U-shaped, and two auxiliary rails are installed at both ends of the support frame. The transport aircraft runs on the track, and the auxiliary rails maintain the balance of the left and right ends of the transport aircraft. During the transport of goods, the transport aircraft can automatically detect its own tilt angle. When the tilt angle deviates, it can automatically adjust the horizontal position of the transport aircraft's cargo box to keep the cargo box in a horizontal state, achieving the purpose of automatic leveling. The operating speed of the transport aircraft is adjusted by detecting the speed of the transport aircraft to make it run at the set speed. An electromagnetic braking device is used to brake the transport aircraft to prevent the goods from falling and to enable emergency braking in case of emergencies. The support includes a crossbar and uprights. The track includes a groove and a rack. The crossbar is installed on the support column and is fixed at both ends by two uprights. Each upright supports an auxiliary rail. Two self-stabilizers are installed between the transport machine and the two auxiliary rails to prevent the transport vehicle from swaying from side to side. The middle of the track is set as a groove and the right side is set as a rack. The groove is used to provide guidance for the operation of the transport machine. The rack meshes with the gear of the transport vehicle to provide the transmission basis for the transport machine and also plays a guiding role. The self-stabilizing device includes hydraulic shock absorbers, a third caster, a slider, and a telescopic motor. Self-stabilizing devices are installed on both the left and right sides of the cargo box. The bottom of the telescopic motor is fixed to the frame, and its extension rod is connected to the slider. The third caster is connected to the slider via hydraulic shock absorbers, which push the third caster into the groove of the auxiliary rail. When the cargo box shifts to the left or right due to uneven force, the hydraulic shock absorbers push the cargo box back to a balanced position. As the transport vehicle moves, the third caster moves within the groove of the auxiliary rail. When the front or rear of the cargo box is hydraulically lifted, the controller controls the telescopic motor to pull the slider down, keeping the third caster and the auxiliary rail at the same level, preventing the self-stabilizing device from breaking due to the tilt of the cargo box.

The controller controls the output of the motor speed controller, thereby controlling the motor speed. The motor shaft is connected to the gearbox, and the output of the gearbox is connected to the transmission.

The electromagnetic brake device is installed at the bottom of the frame for braking the transport machine. The first displacement sensor and the second displacement sensor are respectively installed at the bottom of both ends of the cargo box to detect the distance between the two ends of the cargo box and the frame, so that the controller can adjust the extension and retraction of the hydraulic top, thereby adjusting the cargo box to the same horizontal plane.

3. The rail transport machine level monitoring and automatic leveling system according to claim 2, characterized in that: The electromagnetic braking device includes springs, relays, electromagnets, and an iron block. Two springs connect the iron block to the bottom of the frame, with the iron block positioned above the track. The relay and electromagnet are mounted at the bottom of the frame.

The controller controls the on / off state of the relay, thereby controlling the operation of the electromagnet. When braking is not needed, the controller controls the relay to open, energizing the electromagnet and generating a magnetic field, which attracts the iron block, causing it to leave the track. When braking is needed, the controller stops the motor, and the gears and rack engage to brake the transport mechanism. At this time, the controller controls the relay to close, disconnecting the power to the electromagnet. Under the action of the springs, the iron block is pushed onto the track, utilizing the friction between the iron block and the track to achieve secondary braking.
4. The rail transport machine level monitoring and automatic leveling system according to claim 2, characterized in that: The automatic leveling scheme for the transport aircraft is as follows: When the transport aircraft encounters a downhill section, the tilt angle of the leading nose changes. A first tilt angle sensor collects this change information and transmits it to the controller. The controller then controls the output of the motor speed controller, thereby controlling the motor speed to prevent the transport aircraft from overspeeding and tipping over. Next, a second tilt angle sensor transmits its collected information to the controller. Because the front of the cargo box is lower than the rear when the transport aircraft is going downhill, the controller raises the hydraulic jack at the bottom of the front of the cargo box. The second tilt angle sensor continuously collects the tilt angle of the cargo box until... Once the cargo box is level, the controller stops the hydraulic jacks. When the second tilt sensor detects that the front of the cargo box is higher than the rear, the controller retracts the hydraulic jacks at the bottom of the front of the cargo box to lower its height, bringing the front and rear of the cargo box to the same level. As the front of the cargo box rises, the first displacement sensor constantly monitors the distance between the front of the cargo box and the vehicle frame. Based on the displacement information from the first displacement sensor, the controller retracts the telescopic motors on both sides of the cargo box, pulling the stabilizer down. When the hydraulic jacks at the bottom of the front of the cargo box retract, the controller extends the telescopic motors, pulling the stabilizer down. The device moves upwards, ensuring the stabilizer remains level with the auxiliary rail. When the transport vehicle encounters an uphill section, the tilt angle of the leading head changes. This change is collected by the first tilt sensor and transmitted to the controller. The controller then adjusts the output of the motor speed controller, increasing the motor speed to maintain a constant speed as the transport vehicle climbs. Next, the second tilt sensor transmits its collected information to the controller. Because the front of the cargo box is higher than the rear when the transport vehicle goes uphill, the controller raises the hydraulic jack at the rear of the cargo box. The second tilt sensor continuously collects data... The tilt angle of the cargo box is adjusted until the cargo box is level. Only then does the controller stop the hydraulic jack. As the front of the cargo box rises, the second displacement sensor constantly monitors the distance between the rear of the cargo box and the frame. Based on the displacement information from the second displacement sensor, the controller controls the telescopic motors on both sides of the cargo box to retract, pulling the stabilizer down. When the hydraulic jack at the bottom of the rear of the cargo box retracts, the controller controls the telescopic motor to extend, moving the stabilizer upward so that the stabilizer always remains at the same level as the auxiliary rail. When the transport vehicle is traveling on a level road, the controller does not need to adjust the hydraulic jack and telescopic motor.
