Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machinery, in particular to a positioning and force bearing device of a maglev ground module and the maglev ground module. BACKGROUND

[0002] The electric suspension maglev ground module is installed on the side wall track beam of a train, interacts with the superconducting magnet installed on the maglev train, and provides propulsion force, suspension force and guiding force for the maglev train, and is an important part of the maglev track transportation system. How to transmit the force of the ground module to the track beam is the main problem of the installation of the ground module.

[0003] In addition, the track beam on which the ground module is installed is usually cast from concrete, and the bolt sleeve for installing the ground module needs to be pre-buried in the side wall of the track beam. The pre-buried precision of the bolt sleeve will greatly affect the installation precision of the ground module. Therefore, a post-precision adjustable installation device or method is needed to ensure the installation precision of the ground module.

[0004] For the concrete track beam used for experiments, the modules to be installed are usually not only one kind, so it is necessary to prevent the installation components from interfering when different ground modules are installed. SUMMARY

[0005] The present application provides a positioning and force bearing device of a maglev ground module and the maglev ground module, which can solve the technical problems in the prior art.

[0006] The present application provides a positioning and force bearing device of a maglev ground module, wherein the device comprises a first pre-buried part, a second pre-buried part, a detachable anchoring plate, a C-shaped fastener, a wedge key, a detachable connecting unit and an adjusting unit. The first pre-buried part and the second pre-buried part are pre-buried in the track beam. The detachable anchoring plate is detachably connected with the first pre-buried part as a force bearing component of the ground module in the propulsion direction and the suspension direction. The C-shaped fastener cooperates with the ground module and the detachable anchoring plate through the wedge key to transmit the suspension force and the propulsion force on the ground module to the track beam through the detachable anchoring plate, and the wedge key is used to adjust the gap between the C-shaped fastener and the detachable anchoring plate and adjust the gap between the detachable anchoring plate and the ground module. The detachable connecting unit cooperates with the second pre-buried part to detachably connect the ground module with the track beam to transmit the guiding force on the ground module to the track beam. The adjusting unit cooperates with the detachable connecting unit to adjust the position of the ground module in the guiding direction.

[0007] Preferably, the adjustment unit is a set screw, which pushes the ground module against the surface of the track beam through the set screw hole of the ground module, causing the ground module to leave the surface of the track beam, and cooperates with the detachable connection unit to adjust the position of the ground module in the guide direction.

[0008] Preferably, both the first embedded part and the second embedded part are provided with grooves to prevent them from being pulled out and rotated.

[0009] Preferably, the first embedded part has a light hole inside, and the detachable anchor plate is inserted into the light hole and connected to the first embedded part through a connector.

[0010] Preferably, the first embedded part, the second embedded part, and the detachable anchor plate are made of non-magnetic metal material.

[0011] Preferably, the non-magnetic metal material is 304 stainless steel.

[0012] Preferably, the detachable connection unit is a bolt.

[0013] Preferably, the second embedded part has a threaded hole inside, and the bolt is threadedly engaged with the threaded hole to connect with the second embedded part.

[0014] The present invention also provides a magnetic levitation ground module, which includes the above-mentioned positioning and load-bearing device.

[0015] The above technical solution allows the levitation and propulsion forces of the ground module to be transferred to the track beam via C-type fasteners, wedge keys, and detachable anchor plates. The guiding force of the ground module is transferred to the track beam via detachable connecting units. Furthermore, the detachable anchor plates, detachable connecting units, and adjustment units enable fine-tuning of the ground module's position in three directions on the track beam. Since both the anchor plates and connecting units are detachable, different ground modules can be installed on the same section of the track beam. Attached Figure Description

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0030] In this invention, the track beam is used to provide an installation interface for the ground module, and the interaction between the ground module and the superconducting magnet provides the train with propulsion, levitation and guidance forces.

[0031] like Figures 1-5 As shown, this embodiment of the invention provides a positioning and load-bearing device for a magnetic levitation ground module. The device includes a first embedded part 8, a second embedded part 9, a detachable anchor plate 3, a C-shaped fastener 4, a wedge-shaped key 5, a detachable connecting unit 6, and an adjustment unit 7. The first embedded part 8 and the second embedded part 9 are embedded in the track beam 1. The detachable anchor plate 3 is detachably connected to the first embedded part 8 as a load-bearing component of the ground module 2 in the propulsion and levitation directions. The C-shaped fastener 4 cooperates with the ground module 2 and the detachable anchor plate 3 through the wedge-shaped key 5 to position the ground module 2 in the propulsion and levitation directions. The levitation force and propulsion force on the ground module 2 are transmitted to the track beam 1 through the detachable anchor plate 3. The wedge key 5 is used to adjust the gap between the C-type fastener 4 and the detachable anchor plate 3, as well as the gap between the detachable anchor plate 3 and the ground module 2. The detachable connection unit 6 cooperates with the second embedded part 9 to detachably connect the ground module 2 and the track beam 1 to transmit the guiding force on the ground module 2 to the track beam 1. The adjustment unit 7 cooperates with the detachable connection unit 6 to adjust the position of the ground module 1 in the guiding direction.

[0032] The above technical solution allows the levitation and propulsion forces of the ground module to be transferred to the track beam via C-type fasteners, wedge keys, and detachable anchor plates. The guiding force of the ground module is transferred to the track beam via detachable connecting units. Furthermore, the detachable anchor plates, detachable connecting units, and adjustment units enable fine-tuning of the ground module's position in three directions on the track beam. Since both the anchor plates and connecting units are detachable, different ground modules can be installed on the same section of the track beam, ensuring no interference occurs when installing other types of ground modules.

[0033] According to one embodiment of the present invention, there are two C-type fasteners 4 and three wedge keys 5. The two C-type fasteners 4 are set on the left and right sides (i.e., in the pushing direction) of the detachable anchor plate 3 by snap-fit. A wedge key 5 is set between the left C-type fastener 4 and the left side of the detachable anchor plate 3, and a wedge key 5 is set between the right C-type fastener 4 and the right side of the detachable anchor plate 3. A wedge key 5 is set between the ends of the two C-type fasteners that contact the ground module (i.e., a wedge key is set between the ground module and the detachable anchor plate), as shown in Figure 3.

[0034] The ground module 2 may have a pre-set mounting groove, which is adapted to a detachable anchor plate 3 equipped with C-type fasteners 4 and wedge keys 5 to enable the installation and adjustment of the ground module 2. For example, the mounting groove can be rectangular, and the C-type fasteners can fit against the two short sides of the rectangular mounting groove, with the wedge keys on both sides acting between the C-type fasteners and the sides of the anchor plate.

[0035] For example, by adjusting the positions of the three wedge keys 5, the position of the ground module in the levitation (y) and propulsion (x) directions can be adjusted through the interaction between the C-type fasteners and the wedge keys and the ground module (i.e., fine adjustment of the installation position in the levitation and propulsion directions), and the levitation force and propulsion force of the ground module are transferred to the track beam (i.e., the levitation force and propulsion force of the ground module are transferred to the anchor plate, and the anchor plate transfers the levitation force and propulsion force to the track beam).

[0036] Specifically, by adjusting the gap between the C-type fastener 4 and the detachable anchor plate 3 using the wedge keys 5 on the left and right sides, the position of the ground module's advancing direction can be adjusted; by adjusting the gap between the detachable anchor plate 3 and the ground module 2 using the wedge keys 5 on one side of the ground module 2, the position of the ground module's levitation direction can be adjusted.

[0037] According to one embodiment of the present invention, the adjustment unit 7 is a set screw. The set screw pushes against the surface of the track beam 1 through the set screw hole of the ground module 2, causing the ground module 2 to leave the surface of the track beam 1, and cooperates with the detachable connection unit 6 to adjust the position of the ground module 1 in the guide direction.

[0038] For example, the set screw can first be screwed into the set screw hole reserved in the ground module, and then pushed against the surface of the track beam to make the ground module leave the surface of the track beam. The position adjustment of the guiding direction of the ground module can be achieved through the cooperation of the set screw and the detachable connection unit.

[0039] By adjusting the set screws, the position of the ground module in the guide (z) direction can be adjusted (i.e., fine-tuning of the guide direction installation position can be achieved), and the guide force can be transmitted to the track beam through the detachable connection unit. This ensures high accuracy of the ground module in the guide position.

[0040] According to one embodiment of the present invention, both the first embedded part 8 and the second embedded part 9 are provided with grooves to prevent pull-out and rotation.

[0041] This ensures the stability of the connection.

[0042] According to one embodiment of the present invention, the first embedded part 8 has a light hole inside, and the detachable anchor plate 3 is inserted into the light hole and connected to the first embedded part 8 through the connector 10.

[0043] The connecting component can be a bolt.

[0044] The detachable anchor plate and the first embedded part can be removed by unscrewing the bolts.

[0045] According to one embodiment of the present invention, the first embedded part 8, the second embedded part 9 and the detachable anchor plate 3 are made of non-magnetic metal material.

[0046] Using non-magnetic metal materials can give the anchor plate and the embedded parts high rigidity as a whole, which can be used as a reference point for adjusting the position of the ground module.

[0047] According to one embodiment of the present invention, the non-magnetic metal material is 304 stainless steel.

[0048] Those skilled in the art should understand that the above description of materials is merely exemplary and not intended to limit the present invention. Other non-magnetic metallic materials with high strength can also be applied to the present invention.

[0049] According to one embodiment of the present invention, the detachable connection unit 6 is a bolt.

[0050] That is, the ground module is connected to the track beam by bolts and the second embedded part, and the guiding force of the ground module is transmitted to the track beam by bolts.

[0051] According to one embodiment of the present invention, the second embedded part 2 has a threaded hole inside, and the bolt is threadedly engaged with the threaded hole to connect with the second embedded part 2.

[0052] That is, the second embedded part is connected to the bolt by a thread.

[0053] This invention also provides a magnetic levitation ground module, which includes the positioning and load-bearing device described in the above embodiments.

[0054] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0055] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0056] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
