Description

TECHNICAL FIELD

[0001] The present application relates to the field of magnetic levitation track technology, and in particular to a connecting assembly and a connecting method of a magnetic levitation track beam and a functional piece. BACKGROUND

[0002] The significant difference between a magnetic levitation train and a conventional wheel-rail train is that the magnetic levitation train realizes non-contact suspension and guidance between the train and the track by electromagnetic force, and then drives the train to run by using a linear motor. The conventional magnetic levitation train is kept in vertical suspension by the interaction between electromagnets on a train suspension frame and long stator coils on a track, and is kept in horizontal clearance by the attraction between side electromagnets on the suspension frame and side guiding surfaces on the track. The suspension gap between the train and the track is small, generally only about 10 mm. The highest speed of the conventional magnetic levitation train can reach 600 km / h in theory.

[0003] The existing magnetic levitation track line is generally of an overhead type, and uses a monolithic or composite track beam. The top of the track beam is connected with a functional piece on which a stator of a linear motor and other electrical components are installed. Since the magnetic levitation train runs at a high speed and the suspension gap is small, high installation precision of the track beam top and the functional piece is required. In order to meet the installation precision requirement, the entire track beam (generally 25-30 meters long) needs to be placed on a precision machine tool under constant temperature conditions for processing. Therefore, a beam manufacturing plant with several large machining workshops equipped with constant temperature devices needs to be built along the magnetic levitation track line. The equipment required to be equipped in these large machining plants is expensive, the processing process is complex and time-consuming, the land occupation is large, and the cost is high. Moreover, since the installation precision of the track beam and the functional piece is very high, the polishing cost of the corresponding connecting surface is also high. SUMMARY

Without more limitations, the element defined by the sentence "including a…" does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0031] In the specific embodiments, the connecting assembly provided by the present application is used in the technical field of maglev track, and the connecting assembly comprises a maglev track beam and a functional part. The functional part is a functional part connected with the maglev track beam on the maglev track, for example, a functional part for installing a stator of a linear motor or other electrical components. The structure and function of the maglev track beam and the functional part are exemplarily described, which does not limit the function of the connecting assembly provided by the embodiments of the present application in any way.

[0032] As shown in FIG. 1, the connecting assembly comprises a maglev track beam 1 and a functional part 3. The maglev track beam 1 is a long strip-shaped structure, and the functional part 3 is connected with the maglev track beam 1. The functional part 3 is a functional part for installing a stator of a linear motor or other electrical components. Figure 1The connecting assembly comprises a maglev track beam 1, a pre-embedded plate 2, a functional part 3 and a connecting plate 4. The pre-embedded plate 2 comprises a pre-embedded part 2a fixed in the interior of the maglev track beam 1 and a connecting part 2b protruding from the end face 12 of the maglev track beam; the connecting plate 4 is fixedly connected with the functional part 3 and protrudes from the end face 13 of the functional part; wherein the connecting part 2b and the connecting plate 4 are adjustably positioned and fixedly connected to position and fixedly connect the maglev track beam 1 and the functional part 3.

[0033] Specifically, Figure 1 The maglev track beam 1 shown in the figure is a part of the maglev track beam, i.e. the upper flange of the maglev track beam, which needs to be connected with the functional part 3 to meet the actual functional requirements. The maglev track beam 1 is provided with the pre-embedded plate 2, a part of which is arranged in the interior of the maglev track beam 1 as the pre-embedded part 2a, and the other part protrudes from the end face 12 of the maglev track beam as the connecting part 2b. The connecting plate 4 is fixedly connected with the functional part 3 and protrudes from the end face 13 of the functional part, and the specific connection mode between the connecting plate 4 and the functional part 3 can be welding, bolt connection or integral forming. The length of the pre-embedded part 2a fixed in the interior of the maglev track beam 1, the length of the connecting part 2b protruding from the end face 12 of the maglev track beam and the length of the connecting plate protruding from the end face 13 of the functional part need to be adjusted according to the actual stress condition through calculation, and the width of the connecting part 2b and the connecting plate 4 needs to be determined according to the actual stress condition. For example, when the volume and mass of the functional part are small, the length and width thereof can be controlled to be relatively small to reduce the connecting space while meeting the stress requirement.

[0034] The connecting part 2b and the connecting plate 4 are adjustably positioned. Specifically, the connecting plate 3 can be moved along the direction parallel to the end face or the direction perpendicular to the end face, or can be rotated around the connecting part 2b. In addition, the adjustment of the relative position comprises first large-amplitude adjustment and then small-amplitude fine adjustment, and the small-amplitude fine adjustment can realize accurate adjustment of the position to facilitate and expedite the installation precision requirement. The connecting plate 2b is connected with the maglev track beam, the connecting plate 4 is connected with the functional part, and the adjustment of the relative position of the connecting plate 2b and the connecting plate 4 drives the adjustment and positioning of the maglev track beam 1 and the functional part 3, thereby realizing the installation precision of the connection between the maglev track beam 1 and the functional part 3.

[0035] Specifically, the positioning of the maglev track beam 1 and the functional part 3 refers to determining the relative positional relationship therebetween.

[0036] The connecting part 2b and the connecting plate 4 are fixedly connected after the adjustment of the relative position. Specifically, the fixed connection mode can be riveting, welding, pouring or a combination thereof. The fixed connection of the connecting part 2b and the connecting plate 4 realizes the fixed connection of the maglev track beam and the functional part connected therewith.

[0037] Optionally, the embedded plate 2 and the connecting plate 4 are metal products; optionally, the embedded plate 2 is a steel embedded plate, and the connecting plate 4 is a connecting steel plate.

[0038] Through the above arrangement, the connecting part 2b and the connecting plate 4 can adjust the relative position, drive the positioning adjustment of the maglev track beam 1 and the functional part 3, and the connection assembly is quick and convenient in adjustment and positioning, accurate and reliable in connection, meets the installation precision of the maglev track beam and the functional part, does not need to use a large machine tool, is convenient for construction, occupies small space, and thus reduces the connection cost.

[0039] In some embodiments, as shown in Figure 1 and Figure 2 , at least one first opening 5 is arranged on the connecting part 2b, and at least one second opening 6 corresponding to the first opening 5 is arranged on the connecting plate 4, the first opening 5 and the second opening 6 are communicated for the connecting piece 7 to pass through, so as to adjust the position of the connecting part and the connecting plate and temporarily fix.

[0040] Specifically, the correspondence of the first opening 5 and the second opening 6 means that the positions of the two can be matched, and the connecting piece 7 can pass through the first opening 5 and the second opening 6 at the same time. The number of the first opening 5 and the number of the second opening 6 are the same, which can be set as one or more, the shape of the first opening 5 and the second opening 6 can be circular or square, etc. The connecting piece 7 temporarily fixes the connecting part 1 and the connecting plate 3 by passing through the first opening 5 and the second opening 6 at the same time, and the size and shape of the connecting piece 7 match the size and shape of the hole. The size of the first opening and the corresponding second opening and the connecting piece passing through the two can allow the connecting part 2b and the connecting plate 4 to adjust the position before being fixed by the connecting piece, for example, the size of the first opening 5 is greater than the size of the second opening 6, the size of the second opening 6 is greater than the size of the connecting piece 7, or the size of the second opening 6 is greater than the size of the first opening 5, the size of the first opening 5 is greater than the size of the connecting piece 7, etc. In addition, the specific positions of the first opening 5 and the corresponding second opening 6 on the connecting part 1 and the connecting plate 3 respectively determine the overlapping area of the connecting part 1 and the connecting plate 3. In order to make the connection more firm, the positions of the first opening 5 and the second opening 6 should be arranged so that the overlapping area of the connecting part and the connecting plate after the two are communicated is as large as possible.

[0041] Optionally, the connecting piece 7 is a high-strength bolt, and the corresponding first opening 5 and the second opening 6 are bolt holes.

[0042] In some embodiments, as shown in Figure 1 and Figure 2 , the diameter of the first opening 5 is greater than the diameter of the second opening 6.

[0043] Specifically, when the relative position of the connecting part 2 and the connecting plate 4, the second opening can be moved within the range of the first opening, or can be moved within the range of the edge of the first opening and allowing the connecting piece to pass, or can be rotated around the first opening within the range of the first opening or the range of the edge of the first opening and allowing the connecting piece to pass. Through the above setting, the relative position of the first opening 5 and the second opening 6 can be adjusted, which leads to the adjustment of the relative position of the connecting part 2 and the connecting plate 4, and at the same time leads to the adjustment and positioning of the relative position of the magnetic levitation track beam 1 and the functional part 3. The adjustment direction can be parallel to the end face, or can be perpendicular to the end face, or can be the rotation of the functional part around the magnetic levitation track beam. Through the above setting, the functional part 3 and the magnetic levitation track beam 1 can be conveniently and quickly adjusted and positioned, and the adjustment accuracy is high.

[0044] The diameter of the first opening 5 is 5-20mm larger than the diameter of the connecting piece 7, and the diameter of the second opening 6 is 2-3mm larger than the diameter of the connecting piece 7. Through such setting, the adjustment and positioning of the magnetic levitation track beam and the functional part is convenient and quick, and the installation accuracy is high.

[0045] In some embodiments, as shown in Figure 2 The wet joint concrete 8 is poured between the magnetic levitation track beam 1 and the functional part 3 to permanently fix the connection.

[0046] Specifically, the wet joint concrete is poured between the magnetic levitation track beam 1 and the functional part 3, not only wrapping and fixing the connecting part between the magnetic levitation track beam 1 and the functional part 3 into an integral, but also permanently fixing the connection between the magnetic levitation track beam 1 and the functional part 3.

[0047] The functional part 3 can be installed with a thin steel plate or other materials as a bottom mold and a side mold, which plays a role of free formwork when pouring the wet joint concrete.

[0048] The side surface of the track beam can extend ordinary steel bars or pre-buried shear nails, which plays a role of enhancing the shear capacity.

[0049] The end surface 12 of the magnetic levitation track beam and the end surface 13 of the functional part can be roughened or treated in other special ways, which plays a role of enhancing the connection with the wet joint concrete.

[0050] Optionally, the wet joint concrete 8 uses a concrete material with good fluidity, fast strength development and excellent mechanical properties; optionally, the wet joint concrete is early strength ultra-high performance concrete or epoxy mortar and the like.

[0051] It should be noted that the wet joint concrete 8 can reach sufficient strength 12-24 hours after pouring, and the connecting precision requirement of the maglev track beam 1 and the functional part 3 can be met after adjusting the position of the connecting part 2b and the connecting plate 4 and temporarily fixing, and the wet joint concrete 8 plays a role of permanently fixing the maglev track beam 1 and the functional part 3 under the condition of reaching sufficient installation precision.

[0052] In some embodiments, as shown in Figure 3 and Figure 4 , the connecting assembly further comprises a pre-embedded reinforcing bar 9, the pre-embedded reinforcing bar 9 comprises an insertion part and an extension part, the insertion part is fixed inside the maglev track beam 1, and the extension part protrudes from the end surface 12 of the maglev track beam; wherein the extension part can pass through the end surface 13 of the functional part 3 to connect the functional part 3.

[0053] Specifically, the number of the pre-embedded reinforcing bar 9 can be one or more, the position of the pre-embedded reinforcing bar 9 can be on one side or both sides of the pre-embedded plate 2, or be parallel to the pre-embedded plate 2. The pre-embedded reinforcing bar 9 can enhance the connection between the maglev track beam 1 and the functional part 3. Preferably, the pre-embedded reinforcing bar 9 is a pre-embedded steel bar.

[0054] It should be noted that the pre-embedded reinforcing bar 9 will not affect the adjustment of the relative position of the connecting part 2 and the connecting plate 4, nor will it affect the adjustment and positioning of the maglev track beam 1 and the functional part 3. This can be achieved by setting an opening larger than the diameter of the pre-embedded reinforcing bar or any other conceivable way in the corresponding position of the functional part 3 where the pre-embedded reinforcing bar 9 is inserted.

[0055] In some embodiments, as shown in Figure 3 and Figure 4 , the extension part of the pre-embedded reinforcing bar 9 is provided with a fastener 10 to fix the extension part and the functional part 3.

[0056] Specifically, the extension part of the pre-embedded reinforcing bar 9 passes through the end surface 13 of the functional part 3, and on one side of the extension end surface, the fastener 10 fixes and connects the functional part 3 and the extension part. Through the above setting, the functional part 3 is fixedly connected with the pre-embedded reinforcing bar 9, and the fixed connection between the functional part 3 and the track beam 1 is enhanced. Optionally, a spherical pad 11 is provided on the extension part of the pre-embedded reinforcing bar between the fastener 10 and the end surface 13 of the functional part 13 and close to the fastener 10, and the spherical pad 11 can adapt to the connection of the functional part 3 and the pre-embedded reinforcing bar 9 at different angles after the functional part 3 is accurately positioned.

[0057] As shown in Figure 5 , the embodiment of the present application further provides a connecting method of a maglev track beam and a functional part. The connecting method is applied to the connecting assembly as shown in Figure 1 , which comprises a maglev track beam, a pre-embedded plate, a functional part and a connecting plate. The connecting method of the maglev track beam and the functional part comprises the following steps:

[0058] Step S101, a pre-embedded plate is arranged on the maglev track beam, the pre-embedded plate comprises a pre-embedded part fixed in the interior of the maglev track beam and a connecting part protruding from the end face of the maglev track beam.

[0059] Specifically, according to the actual stress condition, the pre-embedded plate with a certain width is pre-set in the maglev track beam, the pre-embedded part is a component pre-positioned when the maglev track beam is poured, which is beneficial to the installation and fixation of external engineering components and the maglev track beam. The length of the pre-embedded part fixed in the interior of the maglev track beam and the length of the connecting part protruding from the end face of the maglev track beam, and the width of the pre-embedded part along the end face can be adjusted according to the actual stress condition through calculation.

[0060] Step S102, a connecting plate is arranged on the functional part, the connecting plate is fixedly connected with the functional part and protrudes from the end face of the functional part.

[0061] Specifically, the connecting plate is arranged on the functional part by riveting, welding or one-piece forming, etc. The connecting plate is fixedly connected with the functional part and protrudes from the end face of the side to be connected of the functional part. The connecting plate can extend into the interior of the functional part without affecting the normal use function of the functional part, or can be fixed with the end face of the functional part without deepening into the interior under the condition of firm connection. It should be noted that the length of the connecting plate extending out of the functional part can be adjusted according to the actual stress condition, the width of the connecting plate along the end face direction is equal to or approximately equal to the width of the connecting part along the end face direction, and the position of the connecting plate on the functional part needs to be set according to the position of the connecting part on the maglev track beam and the installation position of the functional part relative to the maglev track beam, which is beneficial to the adjustment of the relative position of the connecting part and the connecting plate.

[0062] Step S103, the relative position of the connecting part and the connecting plate is adjusted.

[0063] Specifically, when adjusting the relative position of the connecting part and the connecting plate, the adjusting can be performed by moving along the direction parallel to the end face, moving in the direction perpendicular to the end face, i.e. making the maglev track beam and the functional part close to or away from each other, or rotating the connecting plate around the connecting part, etc. This adjusting method is convenient and fast, has high positioning accuracy, and is relatively easy to meet the installation accuracy requirement of the maglev track beam.

[0064] Step S104, the connecting part and the connecting plate are fixedly connected, so as to position and fixedly connect the maglev track beam and the functional part.

[0065] Specifically, the connecting part and the connecting plate achieve the adjustment and positioning of the maglev track beam and the functional part by adjusting the relative position thereof to reach sufficient installation precision, and the maglev track beam is fixedly connected after the sufficient installation precision is reached. The fixed connection mode can be riveting, welding, casting or a combination thereof. The connection method of the maglev track beam and the functional part has high installation precision, does not need to use a large machine tool, occupies small space, and thus effectively reduces the connection cost.

[0066] In some embodiments, a pre-embedded reinforcing bar protruding from the end face of the maglev track beam is arranged, and the pre-embedded reinforcing bar is inserted into the functional part before the relative position of the connecting part and the connecting plate is adjusted and fixedly connected. As shown in Figure 6 Figure 5 Steps S201 and S202 are added after steps S101 and S102, and the steps S103 and S104 are continued. Figure 5 Steps S101, S102, S103 and S104 have been described in detail and will not be repeated here.

[0067] Step S201, a pre-embedded reinforcing bar 9 protruding from the end face of the maglev track beam 1 is arranged.

[0068] Step S202, the pre-embedded reinforcing bar is inserted into the functional part.

[0069] Specifically, the pre-embedded reinforcing bar is the same as the pre-embedded plate, and is a component pre-positioned when the maglev track beam is cast. The length of the insertion part of the pre-embedded reinforcing bar fixed in the maglev track beam can be adjusted and set according to the actual stress condition. The length of the protruding part of the pre-embedded reinforcing bar protruding from the end face of the maglev track beam is at least greater than the length of the pre-embedded part or the connecting plate. The length needs to ensure that the pre-embedded reinforcing bar can be inserted into the functional part, and also needs to avoid affecting the normal structure and use function of the functional part. The pre-embedded reinforcing bar plays a role in enhancing the connection between the maglev track beam and the functional part, and ensuring that the functional part will not move in the direction parallel to the end face.

[0070] In some embodiments, after step S104 as shown in Figure 6 , a step of arranging a fastener on the protruding part of the pre-embedded reinforcing bar to fix the protruding part and the functional part is added. After the connecting part and the connecting plate are fixedly connected, the functional part is fixed with the pre-embedded reinforcing bar through the fastener, which enhances the connection between the functional part and the maglev track beam, and ensures that the functional part will not move in the direction of the pre-embedded reinforcing bar. In some embodiments, the connection method further comprises arranging a spherical pad between the end face of the functional part and the fastener and close to the fastener on the protruding part of the pre-embedded reinforcing bar before arranging the fastener on the protruding part of the pre-embedded reinforcing bar. The spherical pad can adapt to the connection of the functional part and the pre-embedded reinforcing bar at different angles after the functional part is accurately positioned.

[0071] ​In some embodiments, after the maglev track beam is positioned and fixedly connected with the functional member, wet joint concrete is cast between the maglev track beam and the functional member. As shown in Figure 7 or 6, step S301 is added after step S104. Figure 5

[0072] Step 301, wet joint concrete is cast between the maglev track beam and the functional member.

[0073] Specifically, after the maglev track beam is fixedly connected with the functional member, concrete is cast on site, and the strength can reach a sufficient level after 12-24 hours, so that the permanent fixation of the maglev track beam and the functional member is realized after the connection part and the connecting plate are adjusted and positioned, that is, after the maglev track beam and the functional member meet the connection precision and are temporarily fixed. Optionally, the functional member can be pre-installed with a thin steel plate or other material as a bottom mold and a side mold, so as to play a role of avoiding formwork when the wet joint concrete is cast. Optionally, the side surface of the track beam can be provided with ordinary steel bars or pre-buried shear nails, so as to play a role of enhancing the shear capacity.

[0074] In some embodiments, the connecting method further comprises: roughening the end surface of the maglev track beam and the end surface of the functional member before casting the wet joint concrete.

[0075] Roughening the end surface of the maglev track beam can improve the adhesion between the maglev track beam and the wet joint concrete, and roughening the end surface of the functional member can strengthen the connection between the functional member and the wet joint concrete, so that the connection and the permanent fixation of the maglev track beam and the functional member are further enhanced.

[0076] The above only describes preferred embodiments of the present application and is not used to limit the protection scope of the present application.
