Description

A horizontal monitoring and automatic leveling system for rail conveyor Technical Field

[0001] The present invention relates to the field of rail conveyors, and in particular to a horizontal monitoring and automatic leveling system for rail conveyors. Background Art

[0002] Agricultural mountain rail transporters are specialized transportation facilities used in agricultural production. They are primarily used to transport agricultural products, agricultural machinery, agricultural materials, and workers and farmers to mountain farms, orchards, and farmlands. Their primary functions are as follows: 1. Improving agricultural production efficiency. Agricultural mountain rail transporters can quickly and safely transport agricultural products from harvesting locations, such as farmlands or orchards, to centralized processing or sales locations, avoiding difficult mountain roads and traffic congestion, thereby improving agricultural production efficiency. 2. Reducing agricultural product losses. During transportation, agricultural products are often susceptible to bumps, collisions, and other factors, which can lead to losses. Agricultural mountain rail transporters can reduce vibration and shock during transportation, ensuring the safety of transported goods and reducing the risk of damage. 3. Improving farmers' productivity. Agricultural mountain rail transporters can quickly and conveniently transport farmers, workers, agricultural machinery, and other materials, significantly reducing the transportation burden on farmers, improving their productivity, and reducing the incidence of work-related injuries. 4. They are environmentally friendly and energy-efficient. Compared with fuel vehicles, agricultural mountain rail transporters use electricity as power, which is more environmentally friendly, reduces exhaust pollution and energy consumption, and helps protect the environment.

[0003] In the existing technology, agricultural products and agricultural materials are mainly transported by manual labor, vehicle transportation, monorail conveyors, and double-track conveyors. Among them, manual transportation is a common method in traditional agricultural production, but it is inefficient and prone to problems such as insufficient manpower and high labor intensity. At the same time, the amount of goods and the distance they can be transported are also limited, and they are extremely susceptible to weather effects. Vehicle transportation can quickly and conveniently transport large quantities of agricultural products or agricultural materials, but in areas with complex and rugged terrain such as mountainous areas, there are many problems, such as narrow roads, steep slopes, easy slippage, and the risk of accidents. At the same time, vibrations and bumps during transportation can easily cause the goods to break, and the cost is high. A monorail conveyor is a device that transports agricultural materials and agricultural products via tracks. The device is installed at a high altitude to transport goods and is suitable for environments with relatively rugged terrain, such as mountainous areas. A double-track conveyor is similar to a monorail conveyor, but it is designed with two parallel tracks, which can greatly increase the carrying capacity and is suitable for long-distance transportation of large quantities of goods and materials. However, the current single-track and double-track transport carriages have poor stability. For example, the transport vehicle on the single track is prone to overturning when turning or when the load on both sides is unbalanced. When the double-track transport vehicle goes up and down slopes, the items in the carriage are very easy to scatter. Technical issues

[0004] In order to solve the above problems, the purpose of the present invention is to provide a rail conveyor horizontal monitoring and automatic leveling system, which adds auxiliary rails on both sides of the monorail transport track to prevent the conveyor from shaking left and right, and adjusts the inclination of the conveyor by detecting the slope condition to make it reach a horizontal state to prevent the transported goods from falling. The conveyor is operated at a set speed through a feedback adjustment device, and an electromagnetic brake system is used to brake the conveyor. This method can prevent the conveyor from shaking left and right and causing rollover, prevent goods from falling, maintain a certain speed of operation, and can perform emergency braking in emergency situations, thereby improving the safety, efficiency and quality of the conveyor. It is scalable and is expected to meet the development trend of modern intelligent manufacturing. It has good application prospects and market demand. Technical Solutions

[0005] In order to achieve the above-mentioned purpose, the present invention provides a rail conveyor level monitoring and automatic leveling system which is implemented as follows:

[0006] A rail conveyor level monitoring and automatic leveling system includes a conveyor, auxiliary rails, brackets, pillars, and tracks. The brackets are fixed on the pillars, and the tracks are installed on the brackets. The brackets are U-shaped, and two auxiliary rails are installed at both ends of the brackets. The conveyor runs on the tracks, and the balance of the left and right ends of the conveyor is maintained by the auxiliary rails. During the process of transporting goods, the conveyor can automatically detect its own inclination angle. When the inclination angle shifts, the horizontal position of the conveyor cargo box can be automatically adjusted to keep the conveyor cargo box in a horizontal state, thereby achieving the purpose of automatic leveling. The running speed of the conveyor is adjusted by detecting its speed, so that the conveyor runs at the set speed, and an electromagnetic brake device is used to brake the conveyor to prevent goods from falling, and emergency braking can be performed in emergency situations.

[0007] The bracket of the present invention includes a crossbar and a vertical pole. The crossbar is installed on a pillar. Two vertical poles are fixed at both ends of the crossbar. Each vertical pole supports an auxiliary rail. Two self-stabilizers are installed between the transporter and the two auxiliary rails to prevent the transporter from shaking left and right.

[0008] The track of the present invention includes a slide groove and a rack. The track is forged from carbon steel. The middle of the track is set as a slide groove, and the right side is set as a rack. The slide groove is used to provide a guide for the operation of the conveyor. The rack is engaged with the gear of the transport vehicle to provide a transmission basis for the conveyor and also plays a guiding role.

[0009] The transporter of the present invention includes a nose, a fuel tank, a generator, a controller, a motor speed regulator, an electric motor, a speed sensor, a transmission, a transmission, a first iron caster, a first inclination sensor, a hydraulic top, an electromagnetic brake device, a second iron caster, a vehicle frame, a cargo box, a second inclination sensor, a first displacement sensor, and a second displacement sensor. The nose and the cargo box are installed on the vehicle frame, and the first iron caster and the second iron caster are respectively provided under the vehicle frame. The fuel tank, the generator, the controller, the motor speed regulator, the electric motor, the speed sensor, the transmission, and the first inclination sensor are all installed in the nose. The fuel tank provides gasoline for the generator, and the gasoline is converted into electrical energy to power the electric motor through the generator. The controller is electrically connected to the motor speed regulator, and the motor speed regulator is electrically connected to the electric motor. The output of the motor speed regulator is controlled by the controller, and then the speed of the electric motor is controlled. The rotating shaft of the electric motor is connected to the transmission, and the output end of the transmission is connected to the transmission. The electric motor drives the transmission, and the transmission drives the transmission, so that the transmission drives the transporter on the track. Two hydraulic tops are used It is installed between the cargo box and the frame to adjust the height of the car body. The electromagnetic brake device is installed at the bottom of the frame and is used for braking the conveyor. 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 contraction of the hydraulic top and then adjust the cargo box to the same horizontal plane. The second inclination sensor is installed at the top of the cargo box to detect the inclination of the cargo box. The first inclination sensor is used to detect the inclination of the nose. The first inclination sensor and the second inclination sensor transmit the collected information to the controller, and the controller controls the hydraulic top to adjust the front and rear height of the cargo box so that the cargo box is in the same horizontal plane to prevent the cargo from falling. The speed sensor is used to detect the running speed of the conveyor 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 feedback adjustment of the conveyor speed so that the conveyor maintains the preset speed. The two second iron casters under the cargo box and the first iron caster under the nose move in the slide groove of the track.

[0010] The transmission device of the present invention includes a transmission shaft and a gear. After the motor is driven by the transmission, it drives the transmission shaft to rotate, and then drives the gear to rotate. After the gear and the rack are engaged, the conveyor can be driven to travel on the track.

[0011] The first iron caster, the second iron caster and the vehicle frame are connected by using a shock absorber.

[0012] The electromagnetic brake device of the present invention includes a spring, a relay, an electromagnet, and an iron block. Two springs are used to connect the iron block to the bottom end of the frame, and the iron block is above the track. The relay and the electromagnet are installed at the bottom end of the frame. The control end of the relay is connected to the controller, the normally open end of the relay is connected to the power output of the generator, and the common end of the relay is connected to the electromagnet. The controller controls the on and off of the relay, and then controls the operation of the electromagnet. When braking is not needed, the controller controls the relay to turn on, so that the electromagnet is energized and generates a magnetic field, which then absorbs the iron block and makes it leave the track. When braking is needed, the controller controls the motor to stop rotating, and the gear and rack engage to brake the conveyor. At this time, the controller controls the relay to turn off, so that the power supply of the electromagnet is disconnected. Under the action of the spring, the iron block is pushed onto the track, and the friction between the iron block and the track is used to achieve secondary braking.

[0013] The stabilizer of the present invention includes hydraulic shock absorbers, a third iron caster, a slider, and a telescopic motor. The stabilizers are respectively installed on the left and right sides of the cargo box. The bottom of the telescopic motor is fixed on the frame, the telescopic rod of the telescopic motor is connected to the slider, and the third iron caster is connected to the slider through hydraulic shock absorbers. The third iron caster is pushed into the slide groove of the auxiliary rail by the hydraulic shock absorber. When the car body deviates to the left or right due to uneven force, the car body is pushed to balance on the left and right due to the action of the hydraulic shock absorber. When the transport vehicle is moving, the third iron caster moves in the slide groove of the auxiliary rail. When the front or rear end of the cargo box is lifted up by the hydraulic pressure, the controller will control the telescopic motor to pull down the slider, so that the third iron caster and the auxiliary rail remain at the same horizontal plane, thereby preventing the risk of the stabilizer being broken due to the tilt of the cargo box.

[0014] The present invention realizes the automatic leveling scheme of the conveyor as follows: when the conveyor encounters a downhill section, the inclination angle of the nose of the conveyor in front will change. The first inclination sensor collects this change information and transmits it to the controller. The controller starts to control the output of the motor speed regulator, and then controls the speed of the motor to prevent the conveyor from overspeeding and causing rollover. Then the second inclination sensor transmits the collected information to the controller. Since the front end of the cargo box is lower and the rear end is higher when the conveyor goes downhill, the controller controls the hydraulic roof at the bottom of the front end of the cargo box to rise. The second inclination sensor continuously collects the inclination angle of the cargo box. The controller will not stop the hydraulic top until the cargo box is in a horizontal plane. When the second inclination sensor detects that the front end of the cargo box is higher than the rear end, the controller controls the hydraulic top at the bottom of the front end of the cargo box to retract to lower the height of the front end of the cargo box so that the front and rear ends of the cargo box are in the same horizontal plane. As the front end of the cargo box rises, the first displacement sensor constantly detects the distance between the front end of the cargo box and the vehicle frame. The controller controls the telescopic motors on both sides of the cargo box to retract according to the displacement information transmitted by the first displacement sensor, and pulls the stabilizer down. When the hydraulic top at the bottom of the front end of the cargo box retracts, the controller controls the telescopic motors to extend to pull the stabilizer down. The stabilizer moves upward, so that the stabilizer always maintains the same horizontal plane with the auxiliary rail. When the transport plane encounters an uphill section, the inclination angle of the nose of the front will change. The first inclination sensor collects this change information and transmits it to the controller. The controller starts to control the output of the motor speed regulator, thereby increasing the speed of the motor, so that the transport vehicle keeps climbing at the same speed. Then the second inclination sensor transmits the collected information to the controller. Since the front end of the cargo box is higher than the rear end when the transport plane goes uphill, the controller controls the hydraulic top at the bottom of the rear end of the cargo box to rise, and the second inclination sensor continuously collects information. The controller controls the hydraulic top to stop working until the cargo box is in the horizontal plane. As the front end of the cargo box rises, the second displacement sensor constantly detects the distance between the rear end of the cargo box and the frame. The controller controls the telescopic motors on both sides of the cargo box to contract according to the displacement information from the second displacement sensor, and pulls the stabilizer down. When the hydraulic top at the bottom of the rear end of the cargo box contracts, the controller controls the telescopic motor to extend and move the stabilizer upward, so that the stabilizer always maintains the same horizontal plane with the auxiliary rail. When the transport aircraft is traveling on a horizontal road, the controller does not need to adjust the hydraulic top and telescopic motor. Beneficial effects

[0015] Since the present invention uses a second inclination sensor to detect the inclination of the cargo box and then adjusts the height of the front and rear of the cargo box, the following beneficial effects can be achieved:

[0016] 1. This invention adds auxiliary rails on both sides of the monorail to prevent the transport vehicle from swaying during operation, thus reducing the risk of cargo falling. Furthermore, by adjusting the inclination of the carriage, the transport vehicle can be kept level, improving transportation safety.

[0017] 2. The present invention adopts a dual brake system, which can improve the braking effect of the transport aircraft on steep slopes, reduce the braking distance, increase overall safety, ensure the safety of the transport vehicle, and prevent accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings.

[0032] Please refer to Figures 1 to 10, which show a horizontal monitoring and automatic leveling system for a rail conveyor in the present invention, including a conveyor 1, an auxiliary rail 2, a bracket 3, a support 4, and a track 5.

[0033] As shown in Figure 1, the bracket 3 is fixed on the pillar 4, and the track 5 is installed on the bracket 3. The bracket 3 is a U-shaped bracket 3, and two auxiliary rails 2 are installed at both ends of the bracket 3. The conveyor 1 runs on the track 5, and the auxiliary rails 2 are used to maintain the balance of the left and right ends of the conveyor 1. This method can prevent the conveyor 1 from shaking left and right and causing rollover. In the process of transporting goods, the conveyor 1 can automatically detect its own inclination. When the inclination is offset, it can automatically adjust the horizontal position of the cargo box 26 of the conveyor 1 so that the cargo box 26 of the conveyor 1 is always in a horizontal state, achieving the purpose of automatic leveling to prevent the transported goods from falling. By detecting the speed of the conveyor 1, its operating speed is adjusted so that the conveyor 1 runs at the set speed, and an electromagnetic brake device 23 is used to realize the braking of the conveyor 1 to prevent the goods from falling. Emergency braking can be performed in emergency situations, thereby improving the safety, efficiency and quality of the conveyor 1. It is scalable and is expected to meet the development trend of modern intelligent manufacturing. It has good application prospects and market demand.

[0034] As shown in Figure 2, the bracket 3 includes a crossbar 6 and a vertical bar 7. The crossbar 6 is mounted on a support 4. Two vertical bars 7 are fixed at both ends of the crossbar 6. Each vertical bar 7 supports an auxiliary rail 2. Two self-stabilizers 8 are installed between the transporter 1 and the two auxiliary rails 2 to prevent the transport vehicle from shaking left and right. By installing the vertical bars 7 and the auxiliary rails 2 at both ends of the crossbar 6, the stability of the entire bracket 3 can be effectively increased. The support 4 plays a supporting role and transfers the gravity of the transporter 1 to the ground, making the transporter 1 run more smoothly. At the same time, the use of the self-stabilizers 8 can further improve the stability of the transport vehicle and prevent it from shaking left and right.

[0035] As shown in Figures 3 and 5, the track 5 includes a chute 9 and a rack 10. The track 5 is forged from carbon steel. The middle of the track 5 is set as the chute 9, and the right side is set as the rack 10. The chute 9 is used to provide a guide for the operation of the conveyor 1. The rack 10 is engaged with the gear 31 of the transport vehicle, providing a transmission basis for the conveyor 1. It also plays a guiding role, ensuring that the transport vehicle travels along the predetermined direction of the track 5 to prevent lateral deviation or deviation. And through the rotation drive of the gear 31, the transport vehicle can be pushed or braked. The rack 10 transmission enables the vehicle to run on the track 5, control the speed and acceleration and deceleration, and meet specific transportation needs.

[0036] As shown in Figure 4, the transport aircraft 1 includes a head 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 transmission 19, a first iron caster 20, a first inclination sensor 21, a hydraulic top 22, an electromagnetic brake device 23, a second iron caster 24, a frame 25, a cargo box 26, a second inclination sensor 27, a first displacement sensor 28, and a second displacement sensor 29. The head 11 and the cargo box 26 are installed on the frame 25, and the first iron caster 20 and the second iron caster 24 are respectively provided under the frame 25. The fuel tank 12, the generator 13, the controller 14, the motor speed regulator 15, the motor 16, the speed sensor 17, the transmission 19, and the first inclination sensor 21 are all installed in the nose 11. The fuel tank 12 provides gasoline for the generator 13, and the generator 13 converts the gasoline into electrical energy to power the motor 16. The controller 14 is electrically connected to the motor speed regulator 15, and the motor speed regulator 15 is electrically connected to the motor 16. The controller 14 controls the output of the motor speed regulator 15, thereby controlling the speed of the motor 16. The rotating shaft of the motor 16 is connected to the transmission 19, and the output end of the transmission 19 is connected to the transmission 18. The motor 16 drives the transmission 19, and the transmission 19 drives the transmission 18, so that the transmission 18 The conveyor 1 is driven to move on the track 5. Two hydraulic jacks 22 are installed between the cargo box 26 and the frame 25 to adjust the height of the carriage. The electromagnetic brake device 23 is installed at the bottom of the frame 25 to brake the conveyor 1. The first displacement sensor 28 and the second displacement sensor 29 are respectively installed at the bottom of the two 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 contraction of the hydraulic jack 22 and adjust the cargo box 26 to the same horizontal plane. The second inclination sensor 27 is installed at the top of the cargo box 26 to detect the inclination of the cargo box 26. The first inclination sensor 21 is used to detect the inclination of the head 11. The first and second tilt sensors 21 and 27 transmit the collected information to the controller 14, which then controls the hydraulic jack 22 to adjust the front and rear height of the cargo box 26, keeping it level and preventing cargo from falling. The speed sensor 17 detects the operating speed of the conveyor 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 implementing feedback control of the conveyor 1's speed, ensuring that the conveyor 1 maintains a preset speed. The two second iron casters 24 below the cargo box 26 and the first iron caster 20 below the nose 11 move within the chute 9 of the track 5. By collecting the speed and tilt information of the conveyor 1 and adjusting the motor 16 and hydraulic jack 22 through the controller 14, the stability of the conveyor 1 is maintained during travel. The feedback signal from the speed sensor 17 allows the conveyor 1 to respond and adjust promptly, ensuring that the cargo box 26 remains level and preventing cargo from falling.

[0037] As shown in Figure 5, the transmission 18 includes a transmission shaft 30 and a gear 31. After the motor 16 is driven by the transmission 19, it drives the transmission shaft 30 to rotate, and then drives the gear 31 to rotate. After the gear 31 engages with the rack 10, it can drive the conveyor 1 to travel on the track 5.

[0038] As shown in Figure 6 , the first and second iron casters 20, 24, and the frame 25 are connected by shock absorbers 32. These absorbers 32 absorb and reduce vibration and impact during the transport of the conveyor 1, thereby minimizing collisions with agricultural products during transportation. The connection between the iron casters and the frame 25 is achieved through the shock absorbers 32, which cushion and reduce the transmission of vibration, effectively reducing the vibration level of the conveyor 1.

[0039] As shown in Figure 7, the electromagnetic brake device 23 includes a spring 33, a relay 34, an electromagnet 35, and an iron block 36. Two springs 33 are used to connect the iron block 36 to the bottom of the frame 25, and the iron block 36 is above the track 5. The relay 34 and the electromagnet 35 are installed at the bottom of the frame 25. The control end of the relay 34 is connected to the controller 14, the normally open end of the relay 34 is connected to the power output of the generator 13, and the common end of the relay 34 is connected to the electromagnet 35. The controller 14 controls the on and off of the relay 34, and then controls the operation of the electromagnet 35. When braking is not required, the controller 14 controls the relay 34 to be turned on. The electromagnet 35 is charged and generates a magnetic field, which then attracts the iron block 36 and makes it leave the track 5. When braking is needed, the controller 14 controls the motor to stop rotating, and the gear 31 engages with the rack 10 to brake the conveyor 1. At this time, the controller 14 controls the relay 34 to turn off, so that the power supply of the electromagnet 35 is disconnected. Under the action of the spring 33, the iron block 36 is pushed onto the track 5, and the friction between the iron block 36 and the track 5 is used to achieve secondary braking. When braking is not needed, the electromagnet 35 is charged and generates a magnetic field to attract the iron block 36 and make it leave the track 5, thereby reducing the energy loss caused by friction. Only when braking is needed will the power supply of the electromagnet 35 be disconnected, and the secondary braking is started to provide appropriate braking force. The two braking methods can improve the braking effect of the conveyor 1 on steep slopes, reduce the braking distance, and increase overall safety.

[0040] As shown in Figure 8, the self-stabilizer 8 includes a hydraulic shock absorber 37, a third iron caster 38, a slider 39, and a telescopic motor 40. The self-stabilizer 8 is installed on the left and right sides of the cargo box 26 respectively. The bottom of the telescopic motor 40 is fixed on the frame 25, and the telescopic rod of the telescopic motor 40 is connected to the slider 39. The third iron caster 38 and the slider 39 are connected through a hydraulic shock absorber 37. The hydraulic shock absorber 37 pushes the third iron caster 38 into the slide groove 9 of the auxiliary rail 2. When the car body deviates to the left or right due to uneven force, the hydraulic shock absorber 37 pushes the car body to balance on the left and right. When the transport vehicle is moving, the third iron caster 38 moves in the slide groove 9 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 down the slider 39 so that the third iron caster 38 and the auxiliary rail 2 remain at the same level, thereby 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 iron caster 38, slider 39 and telescopic motor 40 realizes automatic balancing and stabilization of cargo box 26. When cargo box 26 is subjected to uneven force, self-stabilizer 8 can adjust in time to make cargo box 26 return to equilibrium state to maintain stable transportation.

[0041] As shown in FIG9 , the scheme for realizing automatic leveling of the conveyor 1 of the present invention is as follows: when the conveyor 1 encounters a downhill section, the inclination angle of the nose 11 in front will change, and the first inclination sensor 21 collects this change information and transmits it to the controller 14. The controller 14 starts to control the output of the motor speed regulator 15, and then controls the speed of the motor 16 to prevent the conveyor 1 from overspeeding and causing rollover. Then the second inclination sensor 27 transmits the collected information to the controller 14. Since the front end of the cargo box 26 is lower than the rear end when the conveyor 1 goes downhill, the controller 14 controls the hydraulic top 22 at the bottom front end of the cargo box 26 to rise, and the second inclination sensor 27 continuously collects the inclination angle of the cargo box 26 until the conveyor 1 is overspeeding. After the cargo box 26 is in the horizontal plane, the controller 14 controls the hydraulic top 22 to stop working. When the second inclination 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, so as to lower the height of the front end of the cargo box 26 so that the front and rear ends of the cargo box 26 are in 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. The controller 14 controls the telescopic motors 40 on both sides of the cargo box 26 to retract according to the displacement information transmitted by the first displacement sensor 28, and pulls the stabilizer 8 downward. 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 Stretch, move the stabilizer 8 upward, so that the stabilizer 8 always maintains the same horizontal plane with the auxiliary rail 2. When the transporter 1 encounters an uphill section, the inclination angle of the nose 11 in front will change. The first inclination sensor 21 collects this change information and transmits it to the controller 14. The controller 14 starts to control the output of the motor speed regulator 15, thereby increasing the speed of the motor 16, so that the transport vehicle maintains the same speed to climb up. Then the second inclination sensor 27 transmits the collected information to the controller 14. Since the front end of the cargo box 26 is higher than the rear end when the transporter 1 goes uphill, the controller 14 controls the hydraulic top 22 at the bottom of the rear end of the cargo box 26 to rise, and the second inclination sensor 27 continuously collects the cargo box The controller 14 controls the hydraulic jack 22 to stop working until the cargo box 26 is horizontal. As the front end of the cargo box 26 rises, the second displacement sensor 29 constantly detects the distance between the rear end of the cargo box 26 and the vehicle frame 25. The controller 14 controls the telescopic motors 40 on both sides of the cargo box 26 to retract based on the displacement information transmitted by the second displacement sensor 29, pulling the stabilizer 8 downward. When the hydraulic jack 22 at the bottom of the rear end of the cargo box 26 retracts, the controller 14 controls the telescopic motors 40 to extend, moving the stabilizer 8 upward, so that the stabilizer 8 always remains at the same level as the auxiliary rail 2. When the transporter 1 is traveling on a horizontal section, the controller 14 does not need to adjust the hydraulic jack 22 and the telescopic motor 40. The inclination information detected by the first inclination sensor 21 and the second inclination sensor 27 is used to adjust the transport vehicle speed and the horizontality of the cargo box 26 to keep the cargo box 26 in a balanced state.This helps prevent the transporter 1 from tipping over or becoming unbalanced when traveling downhill or uphill. The automatic leveling solution allows the transporter to maintain a constant speed while climbing uphill, preventing slowdowns or stalls and improving transport efficiency. Furthermore, automatic leveling reduces operator dependency and increases the transporter's level of automation.

[0042] The working principle and working process of the present invention are as follows:

[0043] As shown in Figure 10, the speed sensor 17 is used to detect the running speed of the conveyor 1, and the collected speed information is transmitted to the controller 14. The controller 14 then controls the motor speed regulator 15 to adjust the speed of the motor 16, thereby realizing feedback adjustment of the speed of the conveyor 1, so that the conveyor 1 maintains the preset speed. The controller 14 controls the on and off of the relay 34, and then controls the operation of the electromagnet 35. When braking is not required, the controller 14 controls the relay 34 to turn on, so that the electromagnet 35 is energized and generates a magnetic field, thereby adsorbing the iron block 36 and causing the iron block 36 to 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 conveyor 1. At this time, the controller 14 controls the relay 34 to turn off, so that The power supply of the electromagnet 35 is disconnected, and the iron block 36 is pushed onto the track 5 by the action of the spring 33, and the friction between the iron block 36 and the track 5 is used to achieve secondary braking. When the conveyor 1 encounters a downhill section, the inclination angle of the nose 11 in front will change. The first inclination sensor 21 collects this change information and transmits it to the controller 14. The controller 14 starts to control the output of the motor speed regulator 15, and then controls the speed of the motor 16 to prevent the conveyor 1 from overspeeding and causing rollover. Then the second inclination sensor 27 transmits the collected information to the controller 14. Since the front end of the cargo box 26 is low and the rear end is high when the conveyor 1 goes downhill, the controller 14 controls the hydraulic top 22 at the bottom front end of the cargo box 26 to rise, and the second inclination sensor The sensor 27 continuously collects the inclination angle of the cargo box 26 until the cargo box 26 is in the horizontal plane. The controller 14 controls the hydraulic top 22 to stop working. When the second inclination 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 to lower the height of the front end of the cargo box 26 so that the front and rear ends of the cargo box 26 are in 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. The controller 14 controls the telescopic motors 40 on both sides of the cargo box 26 to retract according to the displacement information transmitted by the first displacement sensor 28, and pulls the stabilizer 8 downward. 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 Stretch, move the stabilizer 8 upward, so that the stabilizer 8 always maintains the same horizontal plane with the auxiliary rail 2. When the transporter 1 encounters an uphill section, the inclination angle of the nose 11 in front will change. The first inclination sensor 21 collects this change information and transmits it to the controller 14. The controller 14 starts to control the output of the motor speed regulator 15, thereby increasing the speed of the motor 16, so that the transport vehicle maintains the same speed and climbs up. Then the second inclination sensor 27 transmits the collected information to the controller 14. Since the front end of the cargo box 26 is higher and the rear end is lower when the transporter 1 goes uphill, the controller 14 controls the hydraulic top 22 at the bottom of the rear end of the cargo box 26 to rise. The second inclination sensor 27 continuously collects the inclination angle of the cargo box 26 until the cargo box 26 is in a horizontal plane.The controller 14 then stops the hydraulic jack 22. As the front end of the cargo box 26 rises, the second displacement sensor 29 constantly monitors the distance between the rear end of the cargo box 26 and the vehicle 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 downward. When the hydraulic jack 22 at the bottom rear end of the cargo box 26 retracts, the controller 14 controls the telescopic motors 40 to extend, moving the stabilizer 8 upward, ensuring that the stabilizer 8 always remains level with the auxiliary rail 2. When the transporter 1 is traveling on a level surface, the controller 14 does not need to adjust the hydraulic jack 22 or telescopic motors 40.
