Description

Technical Field

[0001] The invention relates to the technical field of magnetic levitation launching sled vehicles, and in particular to a launching sled vehicle adopting electromagnetic levitation and propulsion. Background Art

[0002] High-speed electromagnetic propulsion device is a device that uses electromagnetic force to do work and convert electrical energy into kinetic energy. It uses electrical energy as energy, which is much cheaper than rocket propellant, and has strong controllability, can be used frequently and repeatedly, has high acceleration and high limit speed. High-speed electromagnetic propulsion device can be used in many fields such as transportation, logistics, aerospace, and military.

[0003] When the electric maglev (EDS) sled is running, the magnetic field of the on-board magnet cuts through the ground coil to generate induced current and induced magnetic field. The magnetic field of the on-board magnet interacts with the induced magnetic field of the ground coil to generate electromagnetic suspension force and guiding force, thereby realizing the suspension and guidance of the sled. This system has the characteristics of strong carrying capacity, large suspension height, and low track accuracy requirements.

[0004] The existing magnetic levitation sled vehicles and rocket sleds in the prior art usually use steel rails and sliding shoes to achieve support and guidance. On the one hand, the sliding friction between the sliding shoes and the steel rails hinders the movement of the rocket sled in the longitudinal direction, affecting the propulsion efficiency of the rocket sled to a certain extent; on the other hand, the unevenness of the steel rails and the collision between the sliding shoes and the steel rails due to the change of the rocket sled's posture will aggravate the vibration of the rocket sled, and this effect is more significant at high speeds. Summary of the invention

[0005] The present invention provides a launching sled vehicle adopting electromagnetic suspension and propulsion, which can solve the technical problems in the prior art.

[0006] The present invention provides a launch sled vehicle adopting electromagnetic suspension and propulsion, wherein the launch sled vehicle comprises a main beam, a side beam, a cross beam, an aerodynamic profile, a traction beam, a suspension beam, a slide shoe mounting beam, a slide shoe, a propulsion magnet and a suspension magnet, wherein:

[0007] The main beam is connected to the traction beam, the cross beam and the aerodynamic profile to bear the traction braking force. The traction beam is located at the lower side of the main beam, and the cross beam and the aerodynamic profile are located on both sides of the main beam.

[0008] The side beam connects the suspension beam, the cross beam and the aerodynamic profile to bear the suspension force. The suspension beam is located at the lower side of the side beam, and the cross beam and the aerodynamic profile are located at the inner side of the side beam.

[0009] The traction beam connects the propulsion magnet and the main beam, and is used to transmit the traction braking force and the guiding force generated by the propulsion magnet to the skid body and the load. The propulsion magnet is located at the lower side of the traction beam;

[0010] The suspension beam connects the suspension magnet and the side beam, and is used to transmit the suspension force and the guiding force generated by the suspension magnet to the skid body and the load, and the suspension magnet is located at the lower side of the suspension beam;

[0011] The slipper mounting beam connects the slipper and the side beam, and is used to transmit the support and guiding force generated by the interaction between the slipper and the guide rail under emergency conditions. The slipper mounting beam is located outside the side beam, and the slipper is located on the slipper mounting beam.

[0012] Preferably, there are multiple propulsion magnets, and the multiple propulsion magnets are longitudinally arranged on the lower side of the traction beam.

[0013] Preferably, the propulsion magnet is fixedly connected to the traction beam by bolts.

[0014] Preferably, there are multiple suspension magnets, and the suspension magnets are arranged at the lower sides of both ends of the suspension beam.

[0015] Preferably, the suspension magnet is fixedly connected to the suspension beam by bolts.

[0016] Preferably, the levitation magnet and the propulsion magnet comprise an outer dewar, a superconducting coil, an inner dewar, a support and a coolant device.

[0017] Through the above technical solution, the direct contact between the sled body and the ground can be isolated, and unnecessary vibrations caused by the unevenness of the ground and the rails and the friction resistance in the direction of travel can be reduced; at the same time, compared with traditional rocket sleds, this solution uses a linear motor to drive the sled, which can save steps such as rocket fuel filling, making it easier for the sled to launch repeatedly and multiple times.

The suspension beam 8 is located at the lower side of the side beam 1, and the cross beam 2 and the aerodynamic profile 4 are located at the inner side of the side beam 1;

[0027] The traction beam 10 connects the propulsion magnet 7 and the main beam 3, and is used to transmit the traction braking force and the guiding force generated by the propulsion magnet to the skid body and the load. The propulsion magnet 7 is located at the lower side of the traction beam 10;

[0030] Through the above technical solution, the direct contact between the sled body and the ground can be isolated, and unnecessary vibrations caused by the unevenness of the ground and the rails and the friction resistance in the direction of travel can be reduced; at the same time, compared with traditional rocket sleds, this solution uses a linear motor to drive the sled, which can save steps such as rocket fuel filling, making it easier for the sled to launch repeatedly and multiple times.

[0031] In other words, the present invention adopts non-contact electromagnetic propulsion and suspension, optimizes the external excitation input form of the sled, and reduces the propulsion resistance and external vibration excitation of the sled while meeting the large thrust and large load characteristics, thereby improving the running stability and stability of the sled and improving the propulsion performance of the sled. At the same time, compared with the method of using rocket propulsion as the power source, the single launch cost of the sled using electromagnetic propulsion will also be greatly reduced.

[0032] The launch sled vehicle adopting electromagnetic suspension and propulsion described in the present invention can be used as a space launch sled vehicle.

[0033] According to an embodiment of the present invention, there are multiple propulsion magnets 7 , and the multiple propulsion magnets 7 are longitudinally arranged on the lower side of the traction beam 10 .

[0034] That is, a plurality of propulsion magnets are disposed on the lower side of the traction beam in a longitudinally arranged manner.

[0035] According to an embodiment of the present invention, the propulsion magnet 7 is fixedly connected to the traction beam 10 by bolts.

[0036] According to an embodiment of the present invention, there are multiple suspension magnets 6 , and the suspension magnets 6 are arranged at the lower sides of both ends of the suspension beam 8 .

[0037] According to an embodiment of the present invention, the suspension magnet 6 is fixedly connected to the suspension beam 8 by bolts.

[0038] According to one embodiment of the present invention, the levitation magnet and the propulsion magnet include an outer dewar, a superconducting coil, an inner dewar, a support and a coolant device.

[0039] The launch sled vehicle using electromagnetic suspension and propulsion according to the present invention is described below with reference to examples. The launch sled vehicle includes:

[0040] 1 main beam 3, 2 side beams 1, multiple cross beams 2, multiple aerodynamic profiles 4, 1 traction beam 10, 2 suspension beams 8, 4 skid mounting beams 5, 4 skids 9, 3 propulsion magnets 7 and 4 suspension magnets 6. The main beam 3 connects the traction beam 10, the cross beam 2 and the aerodynamic profile 4 to bear the traction braking force; the side beam 1 connects the suspension beam 8, the cross beam 2 and the aerodynamic profile 4 to bear the suspension force; the traction beam 10 connects the propulsion magnet 7 and the main beam 3 to transmit the traction braking force and the guiding force generated by the propulsion magnet to the skid structure body and the load; the suspension beam 8 connects the suspension magnet 6 and the side beam 1 to transmit the suspension force and the guiding force generated by the suspension magnet 6 to the skid structure body and the load; the skid mounting beam 5 connects the skid 9 and the side beam 1 to transmit the support and guiding force generated by the interaction between the skid and the guide rail under emergency conditions.

[0041] Among them, each set of propulsion magnets includes 1 outer dewar, 2 sets of superconducting coils, 2 sets of inner dewars, 8 sets of supports, and multiple sets of refrigerant devices. The propulsion magnets provide a strong magnetic field to achieve traction and braking under the action of the ground linear motor; each set of suspension magnets includes 1 outer dewar, 1 set of superconducting coils, 1 inner dewar, 4 sets of supports, and several sets of refrigerant devices. The suspension magnets provide a strong magnetic field, and the magnetic field cuts the ground suspension guide coil to generate suspension force and guide force. The three sets of propulsion magnets can be arranged longitudinally and fixedly connected to the traction beam in sequence by bolts. The four sets of suspension magnets are arranged at the four corners of the skid and fixedly connected to the suspension beam by bolts. The electromagnetic load generated by the magnets is transmitted along the path of superconducting coil-inner dewar-support-outer dewar-traction beam / suspension beam, and the remaining equipment is installed on the top equipment platform.

[0042] It can be seen from the above embodiments that the present invention adopts a launch sled in the form of electromagnetic suspension and propulsion, and superconducting magnets provide support, guidance and propulsion braking force. Superconducting magnets avoid direct contact between the sled body and the rails while achieving ultra-high propulsion acceleration. The above characteristics can not only reduce the friction resistance in the forward direction of the sled, but also isolate the vibration caused by the unevenness of the rails and roadbed, and can effectively improve the running stability and stability of the sled.

[0043] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0044] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0045] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
