Description

Technical Field

[0001] The present invention relates to the field of transportation technology, in particular to a magnetic levitation rapid freight system, which is mainly used in places such as ports, airports, docks and warehouses with large cargo transportation volumes. Background Art

[0002] With the rapid development of the economy, international trade is becoming more and more frequent, and the import and export volumes of goods are increasing day by day, which directly leads to a huge demand for cargo transportation vehicles. Traditional cargo transportation vehicles are mainly freight trucks and electric trucks.

[0003] Traditional freight trucks are powered by fuel engines and manually driven, which can cause serious environmental pollution and labor-intensive work, which can easily lead to traffic accidents and personal injury. Traditional freight trucks have relatively low transportation efficiency and high maintenance and transportation costs. There is a huge demand for a large number of freight trucks, and the corresponding demand for personnel and supporting facilities is huge. This mode of freight transportation is not conducive to long-term trade development.

[0004] The new energy electric trucks currently in use are powered by battery modules to transport goods and are manually driven. However, when transporting large containers, the battery power is used up too quickly, the charging frequency is high, the battery replacement cycle is very short, and discarded batteries seriously pollute the environment. Manual transportation takes a long time, the work intensity is high, and it is easy to cause personal injury. This mode of freight transportation is not conducive to long-term trade development. Summary of the Invention

[0005] The purpose of the present invention is to provide a magnetic levitation rapid freight system to solve the problems of many drawbacks of the existing freight system.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] A magnetic levitation rapid freight system comprises a track beam, wherein a power supply rail and an induction rail are respectively provided on the lower side and the upper side of the track beam, a running device is provided between the power supply rail and the induction rail, and a bearing device is provided on the running device.

[0008] Furthermore, the running device includes a suspension frame, on which a linear motor is mounted, facing the induction rail, and a skid mounted below the suspension frame, facing the power rail. The linear motor mounted on the suspension frame interacts with the induction rail to provide traction and braking force for the entire running device.

[0009] Furthermore, the suspension frame is equipped with a secondary spring system that supports the load-bearing device, and a shock absorber is installed between the suspension frame and the load-bearing device. The secondary spring system and shock absorber mainly function to attenuate vibration and impact during operation to prevent damage to the transported goods.

[0010] Furthermore, the suspension frame is connected to the carrying device via an articulated system, which mainly transmits the traction and braking force of the running device to the carrying device.

[0011] Furthermore, the suspension frame is equipped with transverse tie rods and shear brackets. The transverse tie rods prevent lateral swinging between the suspension frames and maintain linear motion consistency between the suspension frames. The shear brackets are connected to the running gear via mounting brackets mounted on the side of the running gear, primarily preventing the suspension frames from shaking.

[0012] Furthermore, the bearing device includes a bearing plate, a support rod assembly is provided below the bearing plate, and the running device is supported below the support rod assembly. The support rod assembly mainly functions to transmit bearing force and attenuate vibration and impact.

[0013] Furthermore, the bearing plate is provided with an end coupler, which is used to remove obstacles that appear in the track during operation.

[0014] Furthermore, the load-bearing plate is provided with an end connector assembly, the main function of which is to provide installation space for the articulated device when the load-bearing device is in coupled and reconnected operation.

[0015] Furthermore, the load plate is equipped with an electromagnetic fixing block that slides horizontally and vertically. Its main function is to adjust containers or cargo of different specifications and sizes horizontally and vertically. When energized, the electromagnetic block can firmly fix the displacement of the loaded cargo or container to prevent it from moving. The electromagnetic plate inside the electromagnetic block can monitor the status of the loaded cargo or container in real time through the operation control center to ensure the safety of the loaded cargo or container.

[0016] Furthermore, the supporting device is equipped with an auxiliary filter box, a high-voltage electrical box, a suspension controller, a traction auxiliary box, a traction suspension unit cooling water pump assembly, a linear motor cooling unit assembly, a traction box, a battery charging assembly, and a filter box. The auxiliary filter box primarily functions to limit the short-circuit current on the busbar in the event of an inverter short-circuit, allowing time for the rapid circuit breaker to operate. The high-voltage electrical box primarily controls the on / off function and overcurrent protection of the main circuit. The suspension controller primarily controls the levitation and guidance of the maglev vehicle. The traction auxiliary box primarily converts DC power into variable-voltage, variable-frequency AC power to power the motor. The traction suspension unit cooling water pump assembly primarily provides a cooling source for the traction and suspension systems. The linear motor cooling unit assembly primarily provides a cooling source for the linear motor. The traction box primarily converts DC power into variable-voltage, variable-frequency AC power to power the motor. The battery charging assembly primarily provides emergency low-voltage power to the vehicle. The charging box can power the vehicle's normal low-voltage DC loads and can also be used to charge the battery. The main function of the filter box is to effectively filter out the specific frequency point in the power supply or frequencies other than the frequency point to obtain a power supply with a specific frequency.

[0030] The track beam 1 is a horizontal C-shape with an opening at the top. The interior forms a space for accommodating the power supply rail 2, the running device 3 and the induction rail 4. The two parallel power supply rails 2 are installed and integrated on the lower side of the track beam 1, and the two parallel induction rails 4 are installed and integrated on the upper side of the track beam 1.

[0031] A running gear 3 is installed between the power rail 2 and the induction rail 4, and a carrying device 5 is installed on the running gear 3. The running gear 3 includes a suspension frame 31, a secondary spring system 32, a shock absorber 33, an articulation system 34, a transverse tie rod 35, a shear support 36, and a skid 37. The carrying device 5 includes an end coupler 51, a support rod assembly 52, an end connector assembly 53, a carrying plate 54, and an electromagnetic fixing block 55. The end coupler 51, support rod assembly 52, end connector assembly 53, and electromagnetic fixing block 55 are all mounted on the carrying plate 54.

[0032] The suspension frame 31 is equipped with a linear motor positioned opposite the induction rail 4. This linear motor and the induction rail 4 work together to provide traction and braking for the entire traveling mechanism. The suspension frame 31 is equipped with a secondary spring system 32, which supports the load-bearing device 5. A shock absorber 33 is installed between the suspension frame 31 and the load-bearing device 5. The secondary spring system and shock absorber primarily dampen vibration and impact during operation, preventing damage to transported goods.

[0033] The secondary spring system 32 is fixedly connected to the conical spring integrated in the suspension frame 31, and the conical spring is fixedly connected to the mounting seat and fasteners in the suspension frame 31. The secondary spring system 32 is provided with a circular tube with limiting and fixing functions. The secondary spring system 32 is provided with rubber parts and buffer devices. Its main function during the entire operation process is to support the load-bearing device 5 and the cargo, transmit the force of the load-bearing device 5 and the cargo to the suspension frame 31, filter the vibration and impact generated during the use process, and ensure the stability and smoothness of the operation.

[0034] The shock absorber 33 in the running gear 3 is composed of multiple lateral and vertical single shock absorbers. One end of the shock absorber is fixed to the inner side of the suspension frame 31 through a mounting bracket and fasteners, and the other end is fixed to the lower surface of the load-bearing plate 54 through a mounting bracket and fasteners to attenuate vibration and lateral impact during operation.

[0035] The suspension frame 31 is connected to the load-bearing device 5 via an articulated system 34. The main function of the articulated system 34 is to transmit the traction and braking forces of the running device 3 to the load-bearing device 5. One end of the articulated system 34 is fixedly connected to the inside of the suspension frame 31 via a mounting bracket and a fixed pin. The other end is fixedly connected to the lower surface of the load-bearing plate 54 via a mounting bracket and a fixed pin. The articulated system 34 is equipped with a rubber joint. During operation, it mainly transmits the braking and traction forces of the running device 3 to the load-bearing device 5. The rubber joint is mainly used to cushion the impact of traction and braking forces during operation.

[0036] The suspension frame 31 is equipped with a transverse tie rod 35 and a shear bracket 36. The ends of the transverse tie rod 35 and the shear bracket 36 are fixed to the inner side of each suspension frame through mounting brackets and fixing pins. During operation, the main purpose is to prevent the suspension frame 31 from swinging left and right and shaking its head, which would affect the stability of operation.

[0037] The lower part of the suspension frame 31 is provided with a slide 37 opposite to the power supply rail 2. When the power is cut off and the suspension frame 31 falls, the suspension frame 31 falls directly onto the power supply rail 2 through the slide 37. The slide 37 is used for transition support.

[0038] The end coupler 51 is fixed to the lower surface of the end of the supporting plate 54 by rivets. Sensors are integrated inside. During operation, the operation control center can adjust the system speed, suspension height, etc. through various sensor parameters. The end coupler 51 is cast through a special casting process and has the characteristics of high strength, corrosion resistance, and light weight. During operation, obstacles in the track beam can be removed to ensure the safety of system operation.

[0039] The support rod assembly 52 is made by welding, and the upper part is fixed to the lower surface of the load-bearing plate 54 through a slide groove and fasteners, and the lower part is inserted into the limiting tube of the secondary spring system 32 through a positioning tube. The support rod assembly 52 is provided with an X-shaped pull rod. During operation, the main function of the support rod assembly 52 is to connect the load-bearing plate 54 and the suspension frame 31, and it also has an anti-rolling function.

[0040] The end connector assembly 53 is fixed to the end of the load-bearing plate 54 by rivets. The end connector assembly 53 is provided with a variety of adjustment holes, and can be installed with articulated connection system devices of different models and specifications, so as to realize the connection and reconnection of multiple load-bearing devices, greatly improving the transportation efficiency.

[0041] The electromagnetic fixing block 55 is fixed to the carrier plate 54 by electromagnetic force. An electromagnetic plate is integrated within the electromagnetic fixing block 55, which allows the transportation control center to monitor the status of the loaded cargo in real time. The electromagnetic fixing block 55 can move horizontally and vertically on the surface of the carrier plate 54 to accommodate the transport of cargo of different sizes and specifications, increasing the variety of transported cargo and maximizing transportation capacity and efficiency. The carrier plate 54 can accommodate multiple electromagnetic fixing blocks 55. These blocks do not require manual fixation; simply move them to the appropriate position. Once powered on, the electromagnetic fixing blocks 55 securely secure the cargo being transported.

[0042] The auxiliary filter box 6 and the filter box 14 are fixed to the middle position of the lower surface of the carrier plate 54 through slide grooves and fasteners. During the entire operation process, the supplied current and voltage can effectively filter out the frequency point of a specific frequency or frequencies other than the frequency point, thereby obtaining a power supply of a specific frequency to ensure the safety and stability of operation.

[0043] The high-voltage electrical box 7 is fixed to the middle position of the lower surface of the bearing plate 54 through sliding grooves and fasteners. It can control the on and off of the main circuit during the entire operation process, thereby playing a role in overcurrent protection of the power supply current.

[0044] The suspension controller 8 is fixed to the middle position of the lower surface of the bearing plate 54 through a slide groove and fasteners. It mainly controls the suspension gap and guidance of the entire system during the entire operation process to ensure safety during the operation.

[0045] The traction auxiliary box 9 and the traction box 12 are fixed to the middle position of the lower surface of the bearing plate 54 through slide grooves and fasteners. During the entire operation process, they mainly convert DC power into AC power with variable voltage and variable frequency to provide power for the motor.

[0046] The traction suspension unit cooling water pump assembly 10 and the linear motor cooling unit assembly 11 are fixed to the middle position of the lower surface of the supporting plate 54 through slide grooves and fasteners. Each cooling unit is provided with a cooling water pipe, which is respectively installed around the linear motor of the suspension frame 31 and the lower surface of the supporting plate 54. During the entire operation process, it mainly provides a continuous cooling source for the traction suspension and linear motor to ensure safe operation of the system.

[0047] The battery charging assembly 13 is fixed to the middle position of the lower surface of the supporting plate 54 through slide grooves and fasteners. It specifically includes a battery and a charging box. During the entire operation process, the battery provides emergency low-voltage power for the system, and the charging box can provide power for the system's normal low-voltage DC load and can also be used to charge the battery.

[0048] When the magnetic levitation rapid freight system is not in operation or arrives at a designated station, the skid 37 falls directly onto the power supply rail 2, which transmits the force of the entire system to the track beam 1, and the entire system is in a power-off and static state.

[0049] During operation, the maglev rapid freight system receives a work order from the operations control center. The system immediately wakes up and enters operational mode, performing a self-check to verify that all electrical system parameters are normal. Once these parameters are confirmed, power is applied to the entire system. First, the coils of the levitation frame 31 and the levitation controller 8 are energized, and the entire system, acting on the induction rail 4, generates levitation force, causing the entire system to levitate upward a certain distance. Then, power is applied to the levitation controller 8 and the linear motors on the levitation frame 31, providing traction, braking, and guiding forces for the entire system. The entire running gear 3 then begins operating in response to the commands and signals from the operations control center.

In the scheme of the present invention, each alternative can be arbitrarily combined with any other basic examples and alternatives.
