Description

Technical Field

[0001] The present invention belongs to the technical field of transport equipment, and particularly relates to a self-laying track eccentric wheel transport equipment and an operation method thereof. Background Art

[0002] Traditional vehicles use engines and rotary motors as power systems. The power transmission requires various transmission mechanisms to be transmitted to the drive wheels. The drive wheels generate frictional force by directly contacting the ground to achieve vehicle driving. The power transmission loss in this process is relatively large, and the driving speed is also limited. At the same time, the direct contact between the vehicle drive wheels and the chassis and the contact between components during power transmission by the transmission mechanism greatly increase the frictional loss of traditional vehicles. At the same time, in recent years, with the increasingly prominent contradiction between energy demand and environmental resources, electric drive vehicles have gradually become a research hotspot in the field of road transportation due to their own environmental protection and energy-saving advantages. However, during the operation of electric drive vehicles, the drive wheels will directly bear all the weights including the drive wheels themselves, the chassis, the carrier, and passengers to drive, resulting in a great consumption of the vehicle's energy and relatively low energy-saving effect.

[0003] Under this background, many scholars have proposed various schemes for suspended electric drive vehicles. For example, the invention patent with the patent number CN109204008B discloses a semi-suspended electric maglev vehicle. However, the levitation force of this scheme is provided by the magnetic wheels and the maglev lane equipped with conductor plates. If the vehicle travels a long distance, a large number of levitation lanes and conductor plates are required, resulting in an increase in the overall vehicle cost and poor feasibility. Summary of the Invention

[0004] Aiming at the problem that when the electric maglev vehicle in the prior art travels a long distance, a large number of levitation lanes and conductor plates are required, resulting in an increase in the overall vehicle cost and poor feasibility, the present invention provides a self-laying track eccentric wheel transport equipment and an operation method thereof.

[0005] The technical solution adopted by the present invention is as follows:

[0006] An operation method of a self-laying track eccentric wheel transport equipment includes the following steps:

[0007] Step 1: When the long axis of the eccentric wheel of at least one transport unit rotates to contact the ground, this transport unit bears the load; when the short axis of the eccentric wheel of at least one other transport unit rotates towards the ground, this transport unit lays tracks along the moving direction.

[0008] Step 2: When the transport unit and the eccentric wheel in Step 1 move further along the moving direction, the bearing transport unit will be transformed into a track-laying unit, and the track-laying transport unit will be transformed into a bearing unit.

[0009] Steps 1 and 2 are cycled to achieve the self-laying track operation of the transport equipment.

[0010] Preferably, during the rotation of the eccentric wheel of the carrying unit in step 1 from the long axis to the short axis direction, the alternation from the carrying unit to the track-laying unit is completed; during the rotation of the eccentric wheel of the track-laying carrying unit from the short axis to the long axis direction, the alternation from the track-laying unit to the carrying unit is completed.

[0011] Preferably, the movement of the carrying base is driven by the eccentric wheel driving device and / or the carrying base driving device of the track-laying carrying unit to achieve track laying.

[0012] Preferably, the movement of the carrier is driven by the carrier driving device and / or the carrying base driving device of the carrying unit.

[0013] Preferably, when the long axis of the eccentric wheel contacts the ground, the carrying unit bears the load; during the rotation of the long axis of the eccentric wheel of the carrying unit from the long axis to the short axis direction, the supporting force of the carrying unit on the carrier weakens or disappears; during the rotation of the short axis of the eccentric wheel of the track-laying carrying unit to the long axis direction, the carrying unit provides a supporting force to the carrier.

[0014] Preferably, a support assembly is provided between the carrier and the carrying base to reduce the movement resistance between the track-laying carrying unit and the carrier.

[0015] After adopting this technical solution, a support assembly is provided between the carrier and the carrying base, so that the carrying base provides a supporting force to the carrier through the support assembly, which can reduce the running resistance between the carrying base and the carrier during operation, so as to reduce the wear of the carrier and the carrying base and the energy consumption required for driving.

[0016] Preferably, the length of the wheel surface at the long axis of the eccentric wheel assembly is less than the length of the wheel surface at the short axis, so that the track-laying time of the eccentric wheel assembly during operation is longer than the loading time.

[0017] After adopting this technical solution, the length of the wheel surface at the long axis of the eccentric wheel assembly is less than the length of the wheel surface at the short axis, and most of the wheel surface is used for track laying, so that the track-laying time of the eccentric wheel assembly during operation is longer than the loading time, thereby improving the running speed of the carrier.

[0018] The principle of the operation method in the present invention is as follows:

[0019] The definitions of the long axis and the short axis of the eccentric wheel are as follows: The wheel surface of the eccentric wheel is divided into two parts, and the distances from the two parts of the wheel surface to the center of the eccentric wheel are different. The part of the wheel surface with a larger distance to the center of the wheel is the long axis, and the part of the wheel surface with a smaller distance to the center of the wheel is the short axis. The wheel surface with the farthest distance from the center of the wheel in the long axis is the farthest end of the long axis.

[0020] (1) When the eccentric wheel driving device participates in driving the movement of the carrying base:

[0021] Step 1: Drive the eccentric wheel to rotate, and the rotation direction of the eccentric wheel faces the running direction; the long axis of the eccentric wheel of the bearing unit contacts the ground to bear the weight of the carrier; the short axis of the eccentric wheel of the track laying unit faces the ground, that is, it is suspended or contacts the ground.

[0022] If the short axis of the eccentric wheel contacts the ground, the carrier base is driven to move through the eccentric wheel drive device of the track laying unit and / or the carrier base drive device of the carrier to achieve track laying;

[0023] If the short axis of the eccentric wheel is suspended, the carrier base is only driven to move through the carrier base drive device of the carrier to achieve track laying;

[0024] The carrier is driven to run through the carrier drive device and / or the carrier base drive device of the bearing unit; when driven by the carrier base drive device of the bearing unit, a carrier drive device is provided on the carrier.

[0025] Step 2: As the eccentric wheel rotates, the long axis of the eccentric wheel of the bearing unit in Step 1 gradually rotates towards the short axis direction, and the supporting force of the supporting component on the carrier weakens or disappears;

[0026] During the process of the long axis of the eccentric wheel of the bearing unit rotating towards the short axis direction, if the eccentric wheel always contacts the ground during the rotation, the friction force between the eccentric wheel and the ground provides a thrust along the running direction for the carrier base connected to the eccentric wheel, and the carrier base drive device of the bearing unit gradually changes from driving the carrier together with or independently of the carrier drive device to driving the carrier base together with or independently of the thrust, realizing the transformation from the bearing unit to the track laying unit;

[0027] If the eccentric wheel gradually disengages from the ground during the rotation, the carrier base drive device of the bearing unit gradually changes from driving the carrier together with or independently of the carrier drive device to driving the carrier base, realizing the transformation from the bearing unit to the track laying unit;

[0028] During the process of the short axis of the eccentric wheel of the track laying unit in Step 1 rotating towards the long axis direction, the supporting force of the track laying unit on the carrier gradually increases;

[0029] During the process of the short axis of the eccentric wheel of the track laying unit rotating towards the long axis direction, the friction force between the eccentric wheel and the ground provides a thrust along the running direction for the carrier base connected to the eccentric wheel, and the carrier base drive device of the track laying unit gradually changes from driving the carrier base to driving the carrier together with or independently of the carrier drive device, realizing the transformation from the track laying unit to the bearing unit;

[0030] Steps 1 and 2 are repeated cyclically to achieve the alternating track laying and bearing of different carrier units, thereby realizing the movement of the carrier base and the carrier.

[0031] During the process of the eccentric wheel of the track-laying unit rotating from the short axis towards the long axis, the drive of the eccentric wheel is stopped before the long axis touches the ground. The long axis of the eccentric wheel is driven by the inertia of the eccentric wheel to contact the ground. When the outermost end of the long axis of the eccentric wheel touches the ground, the maximum supporting force is provided for the carrier, causing the track-laying unit to gradually transform into a load-bearing unit.

[0032] (2)When the eccentric wheel drive device does not participate in driving the movement of the carrier base and is only used to drive the eccentric wheel to complete the alternation of the long axis and the short axis:

[0033] When the short axis of the eccentric wheel does not contact the ground during the rotation of the eccentric wheel, when the short axis faces the ground, the eccentric wheel drive device drives the short axis of the eccentric wheel to rotate towards the long axis, so that the long axis of the eccentric wheel contacts the ground to achieve load-bearing.

[0034] When the short axis of the eccentric wheel contacts the ground during the rotation of the eccentric wheel, and the frictional force between the short axis and the ground is sufficient to drive the eccentric wheel to rotate from the short axis towards the long axis, the eccentric wheel drive device may not be provided;

[0035] When the short axis of the eccentric wheel contacts the ground during the rotation of the eccentric wheel, and the frictional force between the short axis and the ground is not sufficient to drive the short axis of the eccentric wheel to rotate towards the long axis, the eccentric wheel drive device drives the short axis of the eccentric wheel to rotate towards the long axis, so that the long axis of the eccentric wheel contacts the ground.

[0036] A self-track-laying eccentric wheel carrier equipment, comprising:

[0037] A carrier;

[0038] A carrier base;

[0039] A carrier drive device;

[0040] A carrier base drive device;

[0041] An eccentric wheel assembly;

[0042] The carrier base is provided with an eccentric wheel assembly, the eccentric wheel assembly contains at least one eccentric wheel, and the eccentric wheel includes a long axis and a short axis;

[0043] The carrier base drive device includes a motor primary and a motor secondary that cooperate with each other, and the motor primary and the motor secondary are respectively arranged on the carrier base and / or the carrier; the carrier base drive device and / or the eccentric wheel assembly drive the carrier base to lay tracks; the self-track-laying operation of the carrier equipment is realized through the alternating track-laying and load-bearing of different eccentric wheel assemblies and the movement of the carrier.

[0044] After adopting this technical solution, this technical solution realizes the adjustment of the supporting force by alternately facing the ground with the long axis and the short axis of the eccentric wheel, automatically completes the alternation of load-bearing and track-laying, and realizes the self-track-laying operation.

[0045] Preferably, it further includes an eccentric wheel driving device, which is connected to the eccentric wheel and used to drive the eccentric wheel to rotate. The eccentric wheel driving device and / or the carrier base driving device drive the carrier base to lay tracks.

[0046] When the eccentric wheel assembly is provided with an eccentric wheel driving device, the carrier driving device can be omitted. The carrier base is driven to lay tracks by the eccentric wheel driving device, and the carrier is driven to move by the carrier base driving device.

[0047] After adopting this technical solution, the eccentric wheel driving device in this technical solution can drive the eccentric wheel to rotate. When the short axis of the eccentric wheel faces the ground, if the short axis does not contact the ground during the rotation of the eccentric wheel, the eccentric wheel driving device drives the short axis of the eccentric wheel to rotate towards the long axis direction, so that the long axis of the eccentric wheel contacts the ground; when the short axis contacts the ground during the rotation of the eccentric wheel and the friction force between the short axis and the ground is not sufficient to drive the eccentric wheel to rotate to the long axis, the eccentric wheel driving device can also drive the eccentric wheel to rotate from the short axis to the long axis direction, so that the long axis of the eccentric wheel contacts the ground to achieve bearing.

[0048] When the short axis of the eccentric wheel can contact the ground, when the carrier unit lays tracks, the friction force between the eccentric wheel and the ground during the rotation of the eccentric wheel will push the carrier base to lay tracks in the running direction. When the thrust is large enough, the carrier base driving device does not need to be started to drive the carrier base to lay tracks. When the thrust is not large enough, the thrust and the carrier base driving device together push the carrier base to lay tracks.

[0049] Preferably, at least one eccentric wheel assembly is provided on one carrier base. At least one eccentric wheel assembly and at least one carrier base form a carrier unit. The carrier unit is divided into a bearing unit and a track-laying unit. At least one bearing unit and at least one track-laying unit form a carrier module;

[0050] When the carrier module only includes one bearing unit and one track-laying unit, the bearing unit and the track-laying unit of the carrier module are arranged horizontally in parallel or vertically in parallel, and the two carrier units alternate between bearing and track-laying; when the carrier module includes multiple bearing units and / or multiple track-laying units, the bearing units and the track-laying units can be arranged in horizontal combination, vertical combination and horizontal-vertical cross combination.

[0051] The cross combination arrangement refers to: the carrier units are arranged in cross combination in the horizontal or vertical direction.

[0052] Preferably, the carrier base includes a support acting part and an eccentric wheel connecting part. A support assembly is provided between the support acting part and the carrier; the support assembly is provided on the carrier and / or the support acting part of the carrier base, and the eccentric wheel connecting part connects the eccentric wheel assembly.

[0053] Preferably, the support assembly is a mechanical support assembly and / or a magnetic levitation support assembly.

[0054] Preferably, the magnetic levitation support assembly includes a vertical levitation support assembly and / or a lateral levitation support assembly;

[0055] The vertical levitation support assembly includes a first vertical levitation magnet and a second vertical levitation magnet that can cooperate to generate a levitation force. The first vertical levitation magnet is vertically arranged on the support acting portion, and the second vertical levitation magnet is vertically arranged on the carrier;

[0056] The lateral levitation support assembly includes a first lateral levitation magnet and a second lateral levitation magnet that can cooperate to generate a levitation force. The first lateral levitation magnet is horizontally arranged on the carrier, and the second lateral levitation magnet is horizontally arranged on the support acting portion.

[0057] Preferably, the mechanical support assembly includes rollers and / or balls, and the rollers and / or balls are arranged on the support acting portion and / or the carrier.

[0058] After adopting this technical solution, by arranging a vertical levitation support assembly on the bottom of the carrier and the support acting portion, the vertical levitation support assembly can be mechanical support or magnetic levitation support, the mechanical support can be ball support or roller support, and the vertical levitation support assembly can preferably be a controllable magnetic levitation assembly, so that the vertical levitation can be adjusted by controlling the presence, absence and magnitude of its magnetic force. Through the mutual cooperation of the vertical levitation support assemblies, the vertical support of the carrier is realized, the stability of the carrier in the vertical direction is maintained, and the rolling resistance of the transportation equipment is reduced, thereby achieving the effect of energy conservation. In addition, due to the adoption of the vertical levitation support assembly, the carrier can move independently in the vertical direction, thus realizing the decoupling of the carrier in the vertical direction.

[0059] The present invention realizes the vertical levitation of the carrier through the first vertical levitation magnet and the second vertical levitation magnet. It should be noted that the first vertical levitation magnet and the second vertical levitation magnet are arranged correspondingly to maximize the overlapping area and enhance the levitation effect in the vertical direction; and both the first vertical levitation magnet and the second vertical levitation magnet are one of a permanent magnet, a superconducting magnet and an electromagnet, and the three magnets can be randomly combined as long as the carrier can be levitated on the transportation base.

[0060] There are two reasons for setting the first vertical suspension magnet and the second vertical suspension magnet as a magnetic suspension assembly. On the one hand, it is to cooperate with two sets of carrier units to alternately support the weight of the carrier and lay tracks. Specifically, by rotating the eccentric wheel, the distance between the first vertical suspension magnet and the second vertical suspension magnet is controlled, thereby adjusting the magnitude of the suspension force between the carrier and the supporting portion. The carrier base driving device drives the carrier base that is completely unloaded or has a small load to lay tracks, realizing the alternation from load-bearing to track-laying or from track-laying to load-bearing. On the other hand, when an electromagnet is used, different magnitudes of suspension force can be generated by controlling the electromagnet to adapt to different terrains and the weight of the carrier, improving the stability of the carrier. When a superconducting magnet is used, the transverse displacement of the supporting portion can be restricted through the pinning effect of superconductivity, so that the transverse suspension support assembly does not need to be provided, reducing the weight of the carrier and / or the carrier base.

[0061] Preferably, the support assembly includes a transverse suspension support assembly. The transverse suspension support assembly includes a first transverse suspension magnet and a second transverse suspension magnet that can cooperate to generate a suspension force. The first transverse suspension magnet is horizontally arranged on the carrier, and the second transverse suspension magnet is horizontally arranged on the supporting portion.

[0062] After adopting this technical solution, by arranging a transverse suspension support assembly between the bottom of the carrier and the carrier base, the movement of the carrier in the transverse direction is restricted, ensuring the transverse stability of the carrier, thereby realizing the decoupling of the carrier in the transverse direction. It should be noted that the first transverse suspension magnet and the second transverse suspension magnet are arranged corresponding to each other to maximize the overlapping area and enhance the transverse stability effect; and both the first transverse suspension magnet and the second transverse suspension magnet are one of a permanent magnet, a superconducting magnet, and an electromagnet, and the three magnets can be randomly combined. Preferably, both the first transverse suspension magnet and the second transverse suspension magnet are permanent magnets, which can save energy consumption.

[0063] Preferably, an installation structure is arranged between the carrier and the carrier base. The installation structure includes an installation groove and an installation block. The installation groove is arranged on the carrier or the carrier base, and the matching installation block is arranged on the carrier base or the carrier. The carrier base driving device and the support assembly are arranged in the installation structure.

[0064] After adopting this technical solution, the carrier and the carrier base are connected by setting an installation groove and an installation block. An installation groove can be opened at the bottom of the carrier, and an installation block is arranged on the carrier base; or an installation groove can be opened on the carrier base, and an installation block is arranged on the carrier. The carrier base driving device and the support assembly are both arranged in the installation structure, improving the space utilization efficiency, simplifying the structural design, and facilitating modular matching and production.

[0065] Preferably, the carrier driving device is a jet device arranged on the carrier.

[0066] After adopting this technical solution, in this technical solution, the jet device is used as the power source for driving the movement of the carrier, so as to achieve the purpose of driving the carrier with a smaller power, and to realize the decoupled drive of the carrier and the carrier base.

[0067] Preferably, when there are multiple carrier bases of the carrier unit, the multiple carrier bases are symmetrically arranged along the longitudinal direction of the carrier.

[0068] After adopting this technical solution, the symmetrical arrangement of the multiple carrier bases along the longitudinal direction of the carrier enables the carrier to achieve stable support and track laying during operation without tilting.

[0069] Preferably, a limiting component for preventing the carrier base from detaching from the carrier is provided on the carrier base. The limiting component can be a convex block provided on the carrier base or a slider or a sliding groove respectively provided on the carrier base or the carrier, as long as it can ensure that the carrier base does not detach from the vehicle body during operation; through the limiting component, it is possible to avoid the separation of the carrier base and the carrier in extreme situations such as bumps or failures.

[0070] The present invention has the following advantages and beneficial effects:

[0071] 1. In the present invention, by alternately orienting the long axis and the short axis of the eccentric wheel towards the ground, the adjustment of the supporting force is realized, so as to automatically complete the alternation of bearing and track laying, and realize self-track laying operation, solving the problem that the existing maglev vehicle can only lay the track in advance, with high cost and limited applicability.

[0072] 2. In the present invention, the carrier unit mainly bears the weight of the carrier, so when the track laying unit lays the track, it does not bear weight or bears a small part of the weight, thereby saving the driving force required for the track laying unit to lay the track.

[0073] 3. In the present invention, when the short axis of the eccentric wheel can contact the ground and the carrier unit lays the track, the friction force between the eccentric wheel and the ground during the rotation of the eccentric wheel will push the carrier base in the running direction. When the thrust is large enough, the driving device of the carrier base can be not started to drive the carrier base to lay the track. When the thrust is not large enough, the thrust and the driving device of the carrier base together push the carrier base to lay the track, which can effectively save the driving force required for track laying.

[0074] 4. In the present invention, the driving device of the carrier base of the carrier unit can drive the movement of the carrier, and it is not necessary to separately arrange a driving device for the carrier, which can reduce the production cost of the carrier.

[0075] 5. In the present invention, it is directly driven by a linear motor to drive the carrier base to achieve the driving form of "self-track laying". Using the linear motor as one of the power sources, the driving system and the suspension system are highly separated, reducing the structural complexity. Description of the Drawings

[0087] As Figures 1-8 shown, a self-laying track eccentric wheel carrier equipment includes:

[0088] A carrier 1;

[0089] A carrier base 4;

[0090] A carrier driving device;

[0091] A carrier base driving device;

[0092] As Figure 1 , 2 shown, there are four carrier bases 4 in total. The four carrier bases 4 are arranged longitudinally and parallelly. The four carrier bases 4 are grouped in pairs to form two carrier units. The two carrier units can be the first and the third as a group, and the second and the fourth as a group; or the first and the fourth as a group, and the second and the third as a group; since the carrier 1 is more balanced and uniform in force when the first and the fourth are in a group, and the second and the third are in a group, the stability of suspension and operation is higher. Therefore, in this embodiment, the first and the fourth are selected as a group to form a carrier unit, and the second and the third are selected as a group to form a carrier unit; the two carrier units alternate between supporting the weight of the carrier 1 and laying the running track of the carrier 1 to form a track-laying unit and a bearing unit;

[0093] In this embodiment, the four carrier bases 4 of each group of carrier units are symmetrically arranged along the longitudinal direction of the carrier 1.

[0094] In this embodiment, the carrier base 4 includes a supporting portion 5 and an eccentric wheel connecting portion 6 which are connected to each other. The supporting portion 5 and the eccentric wheel connecting portion 6 together make the carrier base 4 present a T-shaped structure;

[0095] The eccentric wheel connecting portion 6 is connected with an eccentric wheel assembly. In this embodiment, there are four eccentric wheels 2 in each eccentric wheel assembly, and two are arranged on each side;

[0096] In this embodiment, the eccentric wheel 2 is a cam. AsFigure 7 As shown, for the eccentric wheel 2, the distance from a part of the wheel surface to the wheel center is greater than that from the other part of the wheel surface to the wheel center (R1 > R2). Then, the side with a larger distance from the wheel surface to the wheel center is the major axis 201, and the side with a smaller distance from the wheel surface to the wheel center is the minor axis 202. The farthest point from the wheel center on the major axis 201 is the outermost end 203 of the major axis. In other embodiments, the shape of the eccentric wheel can be other shapes. In this embodiment, during the rotation of the eccentric wheel 2, the minor axis 202 can also contact the ground, and the frictional force between the minor axis 202 and the ground is sufficient to push the eccentric wheel 2 to rotate from the minor axis 202 facing the ground to the major axis 201 facing the ground. Therefore, in this embodiment, the eccentric wheel 2 is not provided with an eccentric wheel driving device.

[0097] The bottom of the carrier 1 is provided with mounting grooves corresponding to the number of the carrier bases 4. The mounting grooves are of a T-shaped structure. In this embodiment, since there are four carrier bases 4, there are also four mounting grooves. Each mounting groove penetrates through from front to back, and the supporting portions 5 of the four carrier bases 4 are respectively arranged in the respective mounting grooves. In this embodiment, the supporting portion 5 is used as a mounting block to form a mounting structure.

[0098] An opening is provided at the bottom of each mounting groove, and the eccentric wheel connecting portion 6 is connected to the supporting portion 5 from the opening at the bottom of the mounting groove. The size of the opening is smaller than the sizes of the supporting portion 5 and the mounting groove to longitudinally limit the supporting portion 5 in the mounting groove. Moreover, a supporting assembly and a carrier base driving device can be arranged between the upper wall of the supporting portion 5 and the upper wall of the mounting groove, so that the integration degree of the carrier structure is high, effectively saving the space of the whole vehicle.

[0099] In this embodiment, the length of the carrier base 4 is greater than the length of the mounting groove, that is, both ends of the carrier base 4 can be located outside the mounting groove at the same time. In other embodiments, bumpers for limiting can be arranged at both ends of the carrier base 4 to form a limiting assembly to prevent the carrier base 4 from detaching from the carrier 1 during operation.

[0100] In this embodiment, the carrier base driving device is a single-secondary single-primary iron-core permanent magnet linear motor, and in other embodiments, it can also be other linear driving motors.

[0101] Such as Figure 5As shown in the figure, the single-secondary and single-primary iron-core permanent magnet linear motor includes a motor secondary 8 composed of several secondary plates arranged in a row along the length direction of the supporting portion 5 on the upper surface of the supporting portion 5. At the position corresponding to the motor secondary 8 on the upper top wall of the installation groove, there is a motor primary 10 composed of several linear motor primary coils arranged in a row along the length direction of the installation groove (in other embodiments, the motor primary 10 can be arranged on the supporting portion 5, and the motor secondary 8 can also be arranged on the groove wall of the installation groove). The linear motor primary coil is composed of an armature winding. The armature winding is composed of a certain number of armature coils connected according to a certain rule. It is the circuit part of the DC motor and is also the part that generates induced electromotive force and electromagnetic torque for electromechanical energy conversion. It is a double-layer fractional-slot concentrated winding, and the double-layer winding is beneficial to improving the thrust density of the motor.

[0102] The linear motor drives the carrier base to move for track laying, and the jet device arranged on the carrier drives the carrier to move.

[0103] In this embodiment, the carrier driving device is a jet device 3; the jet devices 3 arranged at the tail and head of the carrier 1 are selected to eject airflows to push the carrier 1 forward or backward; in other embodiments, the jet device 3 may not be provided, but the carrier 1 can be driven to move solely by the linear motor of the loaded carrier unit; in other embodiments, the carrier 1 can also be driven to move by the jet device 3 and the linear motor of the loaded carrier unit together.

[0104] Embodiment 2

[0105] This embodiment is basically the same as Embodiment 1, except that: the eccentric wheel 2 is connected with an eccentric wheel driving device; in this embodiment, the eccentric wheel driving device is a rotating motor connected to the wheel center, and the rotating motor can drive the eccentric wheel 2 to rotate, so that the eccentric wheel 2 can rotate from the long axis 201 to the short axis 202 direction or from the short axis 202 to the long axis 201 direction.

[0106] In other embodiments, when the eccentric wheel driving device is provided and the short axis 202 of the eccentric wheel 2 faces the ground, the short axis 202 may not contact the ground either. For example, when the eccentric wheel is Figure 3 and 4 shown in the semi-circular structure, if its short axis 202 faces the ground and does not contact the ground, the rotation of the eccentric wheel 2 can be driven by the eccentric wheel driving device to realize the rotation of the short axis 202 from the short axis 202 to the long axis 201 direction.

[0107] In another embodiment, when the eccentric wheel assembly is provided with an eccentric wheel driving device, the carrier driving device can be omitted, and the carrier base can be driven to lay tracks by the eccentric wheel driving device, and the carrier 1 can be driven to move by the carrier base driving device.

[0108] Embodiment 3

[0109] This embodiment is basically the same as Embodiment 1, except that: the carrier base 4 includes a supporting portion 5, and the supporting assembly is arranged between the supporting portion 5 and the carrier 1;

[0110] The supporting assembly is arranged on the carrier 1 and the supporting portion 5 of the carrier base 4, and the supporting assembly is used to support the carrier 1 and ensure that relative movement can occur between the carrier 1 and the carrier base 4;

[0111] As Figure 6 shown, the supporting assembly includes second vertical suspension magnets 9 arranged on the upper walls of each mounting groove of the carrier 1. At the position corresponding to the second vertical suspension magnets 9 on the upper surface of the supporting portion 5, first vertical suspension magnets 7 are arranged. In this embodiment, the second vertical suspension magnets 9 on each mounting groove include superconducting magnets arranged along the length direction of the mounting groove. The superconducting magnets are arranged in Dewars, and the superconducting magnets can reach the required working temperature by introducing cooling media such as liquid nitrogen into the Dewars; in order to maintain the balance of the suspension force, two rows of superconducting magnets are arranged in this embodiment; the first vertical suspension magnets 7 are permanent magnet tracks composed of permanent magnets, and two rows of such permanent magnets are also arranged, just like the superconducting magnets. Of course, in other embodiments, the first vertical suspension magnets 7 can also be superconducting magnets, and the second vertical suspension magnets 9 can be permanent magnets.

[0112] In this embodiment, the superconducting magnets and the permanent magnet tracks form the suspension system of the carrier 1. By adding cooling media such as liquid nitrogen to the Dewars, the superconducting magnets in the Dewars enter the superconducting state. Under the action of the external magnetic field generated by the permanent magnet tracks, superconducting currents induced by the change of the external magnetic field will be generated inside the superconducting magnets. The currents interact with the external magnetic field to generate a suspension force that balances the weight of the carrier 1 itself and a guiding force required for stability. In the suspended state, the dynamic performance of the carrier 1 is significantly improved, and the running stability is enhanced. In this embodiment, through the pinning effect of superconductivity, the lateral displacement of the supporting portion 5 can also be restricted, achieving the effect of ensuring lateral stability without additionally arranging a lateral suspension assembly.

[0113] In this embodiment, two rows of first vertical suspension magnets 7 are respectively arranged on both sides of the motor secondary 8, and the motor secondary 8 is arranged in the middle of the carrier base 4. The perpendicular distances from the two rows of first vertical suspension magnets 7 to the motor secondary 8 are equal.

[0114] Embodiment 4

[0115] This embodiment is basically the same as Embodiment 3, except that: the first vertical suspension magnet 7 is an electromagnet, and the suspension of the carrier 1 is achieved by the cooperation of the electromagnet and the permanent magnet (the positions of the electromagnet and the permanent magnet can also be exchanged); in other embodiments, it can also be that both the first vertical suspension magnet 7 and the second vertical suspension magnet 9 are electromagnets, and the suspension of the carrier 1 is achieved by the cooperation of two oppositely arranged electromagnets; it can also be that both the first vertical suspension magnet 7 and the second vertical suspension magnet 9 are permanent magnets, and the suspension of the carrier 1 is achieved by the cooperation of two oppositely arranged permanent magnets;

[0116] In other embodiments, when the first vertical suspension magnet 7 and the second vertical suspension magnet 9 are electromagnets or permanent magnets, a lateral suspension assembly can also be provided, such as Figure 6 shown, the lateral suspension support assembly includes a first lateral suspension magnet 12 and a second lateral suspension magnet 13 that can cooperate to generate a suspension force. The first lateral suspension magnet 12 is horizontally arranged on the carrier 1, and the second lateral suspension magnet 13 is horizontally arranged on the support portion 5. The first lateral suspension magnet 12 and the second lateral suspension magnet 13 are one of an electromagnet, a permanent magnet, and a superconducting magnet. Preferably, both the first lateral suspension magnet 12 and the second lateral suspension magnet 13 are permanent magnets to save energy consumption.

[0117] Embodiment 5

[0118] This embodiment is basically the same as Embodiment 4, except that: several rotatable rollers 11 are provided on the bottom wall of the installation groove. The several rollers 11 are arranged in two columns, and the two columns of rollers 11 are respectively arranged on the bottom walls on both sides of the bottom opening of the installation groove. When the eccentric wheel 2 rotates to be out of contact with the ground, the support portion moves downward under its own gravity to contact the rollers 11. Since the support assembly is arranged between the top wall of the installation groove and the top wall of the support portion, under the support of the support assembly, the magnetic suspension force between the carrier 1 and the carrier base 4 is sufficient to overcome the gravity of the carrier base 4, and there is no contact between the carrier base 4 and the rollers 11, and the carrier base 4 floats. At this time, the carrier base 4 is driven by the carrier base driving device to move, and the carrier base 4 has no contact with the ground, and only needs to overcome the gravity of the carrier base 4 itself to achieve track laying.

[0119] Embodiment 6

[0120] This embodiment is basically the same as Embodiment 3, except that: the support component that realizes suspension support through magnetic levitation is replaced by a mechanical support component. Specifically, it can be: two liftable bases are arranged on the bottom wall of the installation groove (the telescoping of the bases can be realized by existing electric telescoping structures), and a row (at least one row) of rotatable anti-collision balls or anti-collision rollers are arranged on the bases. When suspension support is required, the bases are lifted, so as to lift the support acting part 5 and make it suspended in the installation groove. At this time, there is no friction between the support acting part 5 and the installation groove, and only the friction between the anti-collision balls or anti-collision rollers and the support acting part 5, which can also achieve the technical effect of reducing the running resistance.

[0121] Embodiment 7

[0122] This embodiment is basically the same as Embodiment 1, except that: in this embodiment, the four carrier bases 4 are arranged horizontally and in parallel. The two carrier bases 4 arranged in parallel in the first and third positions form a carrier unit, and the two carrier bases 4 arranged in parallel in the second and fourth positions form a carrier unit;

[0123] In other embodiments: it can also be eight carrier bases 4. Every four carrier bases 4 form a carrier module, and a total of two carrier modules are arranged longitudinally and front to back; the first carrier base, the fourth carrier base in the first carrier module, the second carrier base in the second carrier module, and the third carrier base form a carrier unit; the second carrier base and the third carrier base in the first carrier module, the first carrier base and the fourth carrier base in the second carrier module form another carrier unit, and the two carrier units alternate between supporting the weight of the carrier 1 and laying the running track of the carrier 1.

[0124] In other embodiments: it can also be a horizontal combination or an intersection combination of longitudinal carrier modules and horizontal carrier modules.

[0125] Embodiment 8

[0126] This embodiment is basically the same as Embodiment 1, except that: there are 3 carrier bases 4 (in other embodiments, the number of carrier bases 4 can be set to odd numbers such as 3, 5, 7, etc. according to factors such as the size of the carrier 1). The three carrier bases 4 are arranged horizontally and in parallel. The carrier base 4 in the middle is used as a single carrier unit alone, and the carrier bases 4 on both sides are used as a carrier unit. The driving force and suspension force of the carrier base 4 in the middle are equal to the sum of the driving forces and suspension forces of the two carrier bases 4 on both sides (if there are other odd numbers, as long as the driving forces and suspension forces of the two carrier units are roughly the same).

[0127] In other embodiments, the three carrier bases 4 are arranged in two rows, where two carrier bases 4 arranged in parallel form one carrier unit, and the other carrier base 4 serves as a separate carrier unit. The carrier unit composed of the two carrier bases 4 can be located at the front side or the rear side.

[0128] Embodiment 9

[0129] This embodiment is basically the same as Embodiment 1, except that: as Figure 8 shown, an installation groove with openings at the top and both ends is provided on the supporting portion 5, and an installation block matching the installation groove is provided on the carrier 1. The installation block is arranged in the installation groove. Two rows of rollers 11 are provided on the upper surface of the installation block, and the support assembly and the carrier base driving device are arranged at the bottom of the installation block and the installation groove.

[0130] Embodiment 10

[0131] This embodiment is basically the same as Embodiment 1, except that: the motor primary 10 is arranged at the bottom of the supporting portion 5, and the motor secondary 8 is arranged at the bottom of the installation groove.

[0132] Embodiment 11

[0133] This embodiment is basically the same as Embodiment 1, except that: the motor primary 10 is arranged on the side of the supporting portion 5, and the motor secondary 8 is arranged on the side of the installation groove.

[0134] Embodiment 12

[0135] As Figures 1-8 shown, a method for operating the self-laying track eccentric wheel carrier equipment includes the following steps:

[0136] (1) When the eccentric wheel driving device participates in driving the carrier base to move:

[0137] Step 1: Drive the eccentric wheel 2 to rotate, and the rotation direction of the eccentric wheel 2 is towards the running direction; the long axis 201 of the eccentric wheel 2 of the load-bearing unit contacts the ground, and the support assembly of the load-bearing unit supports the weight of the carrier 1; the short axis of the eccentric wheel 2 of the track-laying unit faces the ground and is suspended or in contact with the ground. The support assembly can preferably be a magnetic levitation support assembly.

[0138] If the short axis 202 of the eccentric wheel 2 can contact the ground, the carrier base 4 is driven to move through the eccentric wheel driving device of the track-laying unit and / or the carrier base driving device to achieve track laying;

[0139] If the short axis of the eccentric wheel is suspended, the carrier base is only driven by the carrier base driving device to move to achieve track laying;

[0140] The carrier 1 is driven to operate by the carrier driving device and / or the driving device of the carrying base 4 of the carrying unit; when driven by the driving device of the carrying base of the carrying unit, a carrier driving device is provided on the carrier 1.

[0141] Step 2: As the eccentric wheel 2 rotates, the major axis 201 of the eccentric wheel 2 of the carrying unit in Step 1 rotates towards the minor axis direction, weakening or disappearing the supporting force of the carrying unit on the carrier 1;

[0142] During the process of the major axis 201 of the eccentric wheel 2 of the carrying unit rotating towards the minor axis 202, if the eccentric wheel always contacts the ground during the rotation process, the frictional force between the eccentric wheel 2 and the ground provides a thrust along the running direction for the carrying base 4 connected to the eccentric wheel 2, and the driving device of the carrying base of the carrying unit gradually changes from driving the carrier together with or alone with the carrier driving device to driving the carrying base 4 together with or alone with the thrust, realizing the transformation from the carrying unit to the track-laying unit;

[0143] If the eccentric wheel 2 gradually disengages from the ground during the rotation process, the driving device of the carrying base of the carrying unit gradually changes from driving the carrier together with or alone with the carrier driving device to driving the carrying base 4, realizing the transformation from the carrying unit to the track-laying unit;

[0144] During the process of the minor axis 202 of the eccentric wheel 2 of the track-laying unit in Step 1 rotating towards the major axis 201, the supporting force of the track-laying unit on the carrier 1 gradually increases;

[0145] During the process of the minor axis 202 of the eccentric wheel of the track-laying unit rotating towards the major axis 201, the frictional force between the eccentric wheel 2 and the ground provides a thrust along the running direction for the carrying base 4 connected to the eccentric wheel 2, and the driving device of the carrying base of the track-laying unit gradually changes from driving the carrying base to driving the carrier 1 together with or alone with the carrier driving device, realizing the transformation from the track-laying unit to the carrying unit;

[0146] Steps 1 and 2 are repeated cyclically to achieve the alternating track-laying and carrying of different carrying units, thereby realizing the movement of the carrying base 4 and the carrier 1.

[0147] During the process of the minor axis 202 of the eccentric wheel 2 of the track-laying unit rotating towards the major axis 201, stop driving the eccentric wheel 2 before the major axis 201 contacts the ground, and drive the major axis 201 of the eccentric wheel 2 to contact the ground by the inertia of the eccentric wheel 2. When the outermost end 203 of the major axis of the eccentric wheel 2 contacts the ground, the supporting force provided for the carrier 1 is the largest, and the track-laying unit is gradually transformed into the carrying unit.

[0148] (2) When the eccentric wheel driving device does not participate in driving the carrying base and is only used to drive the eccentric wheel to complete the alternation of the major axis and the minor axis:

[0149] When the short shaft 202 of the eccentric wheel 2 does not contact the ground during the rotation of the eccentric wheel 2, when the short shaft 202 faces the ground, the eccentric wheel driving device drives the short shaft 202 of the eccentric wheel 2 to rotate towards the long shaft 201, so that the eccentric wheel 2 contacts the ground to achieve bearing.

[0150] When the short shaft 202 of the eccentric wheel 2 contacts the ground during the rotation of the eccentric wheel 2, and the friction force between the short shaft 202 and the ground is sufficient to drive the eccentric wheel 2 to rotate from the short shaft 202 towards the long shaft 201, the eccentric wheel driving device may not be provided;

[0151] When the short shaft 202 of the eccentric wheel 2 contacts the ground during the rotation of the eccentric wheel 2, and the friction force between the short shaft 202 and the ground is not sufficient to drive the short shaft 201 of the eccentric wheel 2 to rotate towards the long shaft 201, the eccentric wheel driving device drives the short shaft 202 of the eccentric wheel 2 to rotate laterally towards the long shaft 201, so that the eccentric wheel 2 contacts the ground.

[0152] Embodiment 13

[0153] This embodiment is basically the same as Embodiment 12, the difference being that: the length of the wheel surface at the long shaft 201 of the eccentric wheel 2 is less than the length of the wheel surface at the short shaft 202, so that the duration of track laying during the rotation of the eccentric wheel 2 is greater than the duration of bearing. The length of the wheel surface at the long shaft of the eccentric wheel is less than the length of the wheel surface at the short shaft, and most of the wheel surface is used for track laying, so that the duration of track laying during the rotation of the eccentric wheel is greater than the duration of bearing, thereby improving the running speed of the carrier. The length difference between the long shaft 201 and the short shaft 202 of the eccentric wheel 2 can be set as needed, and the gradual transition between the long shaft 201 and the short shaft 202 is preferably ensured to improve the running smoothness.

[0154] The above-described embodiments only represent the specific implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the technical solution of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
