Description

Technical Field

[0001] The invention belongs to the technical field of maglev tracks, and in particular relates to a maglev space curved beam forming system and a forming method. Background Art

[0002] Magnetic levitation technology uses magnets to generate lift and thrust, allowing the vehicle to float very close to the "guide rail". Since there is no friction from physical contact, most of the power is used to overcome air resistance. In terms of operating energy consumption, high-speed maglev has obvious advantages over high-speed railways.

[0003] The track beam of the maglev train is the basis for the operation of high-speed maglev trains. The track beam is a high-precision component in the maglev track structure system. In high-speed maglev technology, since the suspension height and guide clearance of high-speed maglev trains are only 8-10mm, the construction quality and installation quality of the track are extremely demanding. In order to ensure accuracy, large-scale five-axis triple-controlled boring and milling machines are required for processing in current bridge prefabrication technologies at home and abroad, resulting in very high costs for the track beam.

[0004] Maglev track beams are divided into straight beams, curved beams and space curved beams according to their line shape. In addition to being an arc with a certain radius of curvature on the horizontal plane, the space curved beam is also curved in the Z direction. Due to its structural characteristics and requirements on processing accuracy, it further brings great difficulties to the processing and assembly of the space curved beam. Summary of the invention

[0062] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0063] The maglev track beam is usually provided with maglev functional parts 40 on both sides of its beam surface to ensure the operation of high-speed maglev trains. On the maglev space curve beam in the present invention, the maglev functional parts are integrally formed onto the beam when the beam is cast to ensure the installation structural strength of the maglev functional parts on the space curve beam, and can well ensure the installation position accuracy of the maglev functional parts on the space curve beam.

[0064] Here, the magnetic levitation functional parts include a plurality of stator sleeves 41 and an L-shaped steel plate 42 welded by a sliding surface steel plate and a guide surface steel plate. The stator sleeves and the L-shaped steel plates in the magnetic levitation functional parts are independent components and have no connection with each other. Therefore, when the magnetic levitation track beam is cast, the positions of the stator sleeves and the L-shaped steel plates need to be accurately positioned to ensure the position accuracy of the magnetic levitation functional parts on the magnetic levitation track beam.

[0065] For the space curved beam, since it has a certain curvature in the horizontal plane and the Z direction, it not only brings difficulties to the forming of the space curved beam, but also brings great difficulties to the positioning and adjustment of the magnetic levitation functional parts during forming.

[0066] The positioning and installation of maglev functional parts in the forming system is a key link in the manufacturing process of maglev track beams. The installation deviation directly affects the deviation of the stator surface, guide surface and sliding surface, and ultimately affects the running comfort of high-speed maglev trains.

[0067] by Figure 1 and 2 Taking the shown maglev space curved beam as an example, the maglev space curved beam 10 includes a beam body 11 and supports 12 located at both ends of the beam body. The beam body 11 and the supports 12 are integrally cast by concrete. The bottom surface of the beam body is suspended and located above the bottom surface of the support. The outer contour line of the toe cross section of the support 12 is set to be an arc shape.

[0068] By arranging supports at both ends of the beam body and setting the outer contour line of the toe cross-section of the support to an arc shape, it is convenient to use a forming system to realize the forming of the magnetic levitation track beam with support bottom surfaces with different inclination angles when the track beam is formed, thereby meeting the forming requirements of spatial curved beams with different transverse slope angles.

[0069] The outer contour line of the toe cross section of the beam body 11 is in an arc shape to facilitate the integrated molding of the magnetic levitation space curved beam and the design of the molding system structure. Figure 2 As shown, the cross section of the beam body 11 is π-shaped.

[0070] The magnetic levitation functional parts 40 are respectively arranged on the beam wings on both sides of the magnetic levitation space curved beam. When the magnetic levitation track beam is cast, the magnetic levitation functional parts 40 are integrally formed on the beam body 11 and the support 12.

[0071] In view of the above-mentioned problems and the structure of the maglev space curved beam, the present invention sets a functional part positioning assembly in the maglev space curved beam forming system, and designs the structure of the functional part positioning assembly so that it can arbitrarily adjust the spatial position of the maglev functional part according to the shape of the space curved beam, and position and install the maglev functional part on the forming system, which can well solve the problems existing in the overall forming of the maglev space curved beam.

[0072] In some embodiments, reference Figure 3 , Figure 4 and Figure 5 The maglev space curved beam forming system can generally include a bottom mold assembly, a side mold assembly, an end mold assembly and an inner mold assembly.

[0073] The side mold assembly generally includes two side mold plates 241 disposed opposite to each other on both sides of the bottom mold assembly.

[0074] The molding system is also provided with a functional component positioning assembly for positioning the magnetic levitation functional component on the molding system. Corresponding to the magnetic levitation functional components arranged on both sides of the magnetic levitation space curved beam, a group of functional component positioning assemblies are respectively arranged on the two side templates.

[0075] Reference Figure 5 and Figure 6 The functional component positioning assembly includes a plurality of functional component templates 31 for positioning the stator sleeve of the magnetic levitation functional component. The stator sleeve 41 can be fixedly installed on the functional component template 31 by bolts. At this time, the setting position of the stator sleeve on the magnetic levitation track beam can be adjusted by adjusting the spatial position of the functional component template.

[0076] Reference Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 , the functional component template 31, a positioning portion 310 for positioning and installing the stator sleeve of the magnetic levitation functional component is provided on the functional component template, and the stator sleeve 41 can be fixedly installed on the positioning portion 310 of the functional component template by bolts. The stator sleeve includes a stator sleeve 411 with a dovetail groove and a stator sleeve 412 without a dovetail groove, so different positioning structures are set in the positioning portion of the functional component template according to different stator sleeve shapes. Threaded holes for positioning and assembly are respectively provided on the stator sleeve. After the stator sleeve is positioned and installed on the positioning portion, the stator sleeve is fixed to the functional component template by bolts cooperating with the threaded holes set in the stator sleeve.

[0077] An adjustment mechanism capable of adjusting the spatial position of the functional component template is provided between the side template 241 and the functional component template 31 .

[0078] In some embodiments, the adjustment mechanism includes at least two groups of vertical adjustment components and at least two groups of lateral adjustment components. Here, the adjustment mechanism is described by taking the arrangement of two groups of vertical adjustment components and two groups of lateral adjustment components as an example.

[0079] The two groups of vertical adjustment components and the two groups of transverse adjustment components are both arranged along the longitudinal direction of the functional component template. For example, the two groups of vertical adjustment components are respectively arranged at positions close to both ends of the functional component template, and the two groups of transverse adjustment components are also respectively arranged at positions close to both ends of the functional component template. The vertical adjustment components are used to adjust the position of the functional component template at the corresponding position in the vertical direction, so that the position of the functional component template in the vertical direction and its inclination angle along the longitudinal direction can be adjusted; the transverse adjustment components are used to adjust the position of the functional component template at the corresponding position in the transverse direction, so that the position of the functional component template in the transverse direction of the molding system and its inclination angle along the transverse direction can be adjusted. At this time, the spatial position of the functional component template on the molding system can be adjusted through the adjustment mechanism, so that the position of the stator sleeve on the maglev track beam can be arbitrarily adjusted.

[0080] In some embodiments, the vertical adjustment assembly includes at least two vertical adjustment members arranged below the functional part template. Taking the setting of two vertical adjustment members as an example, the two vertical adjustment members are arranged along the lateral direction of the functional part template, and the four vertical adjustment members in the two groups of vertical adjustment assemblies are respectively arranged at positions close to the four corners of the functional part template to adjust the spatial position of the functional part template.

[0081] The vertical adjustment member includes a vertical drive member 32 and a first connector 34. The first connector 34 is connected to the functional member template 31 by rotation and sliding, so that the first connector can rotate around the connection point with the functional member template in a vertical plane along the transverse direction of the functional member template, and can move horizontally along the transverse direction of the functional member template. The vertical drive member is connected to the first connector by a ball joint. The vertical drive member is used to drive the first connector to move in the vertical direction. The vertical drive member is arranged on the side mold assembly.

[0082] The vertical driving member 32 can adopt an electric push rod arranged along the vertical direction. Based on the connection structure between the first connecting head and the functional part template, the functional part template is adjusted through four vertical adjusting members. The four vertical driving members drive the first connecting head to move in the vertical direction to adjust the functional part template to the set spatial position.

[0083] In some embodiments, the vertical drive member 32 is fixedly disposed on a frame cross beam 246 located outside the end of the side formwork.

[0084] The first connector 34 includes a rotating portion 341 and a connecting portion 342 . The rotating portion 341 and the connecting portion 342 form a T-shaped structure. For example, the rotating portion and the connecting portion may be a T-shaped structural member composed of two sections of round tubes.

[0085] The functional component template 31 is provided with two frame plates 311 arranged side by side, and the frame plates 311 are respectively provided with sliding holes 312. The sliding holes can be set as square hole structures, for example. The two ends of the rotating part 341 are respectively arranged in the sliding holes of the two frame plates, so that the rotating part can rotate along the axis of the rotating part in the sliding hole, and can slide in the lateral direction of the functional component template in the sliding hole. The connecting part 342 is arranged between the two frame plates and is in clearance with the two frame plates. For example, the width of the sliding hole can be set to match the diameter of the rotating part, so that the rotating part can rotate along its axis and slide along the length direction of the sliding hole. In addition, the limiting structures can be respectively arranged on the outer sides of the two frame plates on the rotating part, and the limiting structures are used to limit the rotating part from deflecting around the axis of the connecting part when sliding along the length direction of the sliding hole, so as to ensure the stability of the connection between the first connector and the functional component template.

[0086] In this way, by setting the structure of the first connector, the vertical adjustment member can send the functional member template to the set position, and avoid interference between the vertical adjustment members during the adjustment process. The first connector is set to be slidably connected with the functional member template, providing a certain space for adjusting the functional member template in the horizontal direction.

[0087] In some embodiments, the lateral adjustment assembly includes a lateral adjustment member disposed outside the functional member template.

[0088] The transverse adjustment member includes a transverse driving member 33 and a second connecting head 35. The second connecting head 35 is slidably connected to the outer side plate of the functional part template 31, so that the second connecting head can move in the vertical direction on the functional part. The transverse driving member and the second connecting head are connected by a ball joint, which is used to drive the second connecting head to move horizontally in the transverse direction of the functional part template, thereby adjusting the position of the functional part template in the transverse direction of the molding system.

[0089] The transverse driving member 33 can adopt a horizontally arranged transverse electric push rod, which is fixedly arranged on the side mold back 247 located on the outside of the side mold. The side mold back 247 can move with the side mold. The driving end of the transverse electric push rod is connected to the second connecting head by a ball joint. Due to the sliding fitting connection between the second connecting head and the functional part template, it can adjust the functional part template in the transverse direction while providing a certain space for the vertical adjustment component to adjust the functional part template in the vertical direction, and can fix the position of the functional part template in the transverse direction after the adjustment is completed.

[0090] A vertical movable space is provided between the lateral adjustment member and the functional member template at the connection position, so that the functional member template can move in the vertical direction relative to the lateral adjustment member. Fig.10 As shown, a vertical movable groove 313 can be provided on the side of the functional component template, and one end of the second connector 35 extends into the movable groove 315 and forms a sliding fit connection with the movable groove.

[0091] The movable groove is set to provide an adjustment space in the vertical direction for the connection between the lateral adjustment member and the functional member template, so that the lateral adjustment member will not interfere with the adjustment of the functional member template in the vertical direction. At the same time, it can provide a certain movement space for the demoulding of the functional member template when the mold is opened. During the mold opening operation, the vertical adjustment member can be controlled to drive the functional member template to move downward to realize the demoulding of the functional member template, and then the side mold assembly can be demoulded. In this way, the interference between the functional member template and the maglev track beam can be avoided when the side mold assembly is demoulded. Fig.13 As shown, during demoulding, the functional component template is separated from the magnetic levitation functional component cast on the curved beam.

[0092] Here, when adjusting the functional part template, follow-up control can be adopted between the vertical adjustment component and the horizontal adjustment component. For example, through program control, the movement amount of each vertical driving component and the horizontal driving component is calculated through the adjustment position of the functional part template to realize the adjustment of the position of the functional part template.

[0093] In some embodiments, when the forming system forms a section of beam, the spatial curved beam is decomposed into four sections in the longitudinal direction. In this way, according to the spatial position characteristics of the spatial curved beam, the spatial positions of the four sections of functional component templates can be adjusted respectively, and the structural configuration of the spatial curved beam is formed by fitting the four sections of functional component templates. In this way, the forming accuracy of the spatial curved beam can be well guaranteed, and the casting and forming of spatial curved beams with different spatial curve parameters can be better met.

[0094] In some embodiments, the functional component templates 31 are arranged side by side in sequence along the longitudinal direction of the side template, and locking components for fixing the functional component templates are arranged between adjacent functional component templates. In this way, after each functional component template is adjusted into place, the position of the functional component template on the side template is fixed by the locking component to prevent the position of the functional component template from changing during the beam casting process.

[0095] Specifically, the locking assembly includes a plurality of longitudinal driving members 39 arranged at one end of the functional member template. For example, a longitudinal driving member 39 can be arranged at both sides of one end of the functional member template. The longitudinal driving member can adopt a longitudinal electric push rod, so that the driving end of the longitudinal driving member can be pressed against the end face of the adjacent functional member template. When the two adjacent functional member templates are pressed against each other in the longitudinal direction by the longitudinal electric push rod, at this time, based on the action of the vertical adjustment assembly, the lateral adjustment assembly and the locking assembly on the functional member template, the functional member template can be stably fixed in space.

[0096] At this time, the gaps formed between adjacent functional component templates can be filled and sealed with adhesive strips or other structures.

[0097] In order to achieve better conformal setting of the maglev functional components on the maglev track beam and to better position and adjust the position of the maglev functional components along the linear shape of the maglev track beam, the maglev functional components are arranged to be composed of multiple sections on a beam. Taking the maglev track beam with a standard span of 12.384m as an example, the maglev functional components are divided into 4 sections. In this way, by adjusting the positions of the 4 sections of maglev functional components separately, the setting positions of the maglev functional components on the maglev track beam can be adjusted more flexibly, which can better ensure the position accuracy of the maglev functional components.

[0098] Based on the setting of the above-mentioned maglev functional parts, the functional part positioning assembly in the molding system is set to be composed of 4 functional part templates, each functional part template corresponds to a group of maglev functional parts, and is used to independently position a group of maglev functional parts. At this time, the positioning and adjustment of the maglev functional parts on the maglev track beam can be achieved by adjusting the 4 functional part templates.

[0099] By adjusting the position of the functional component template, the position of the stator sleeve set on the functional component template can be adjusted and positioned to control the accuracy of the stator surface. Based on the realization of the above functions, the functional component positioning assembly also includes a steel plate positioning mechanism for positioning the L-shaped steel plate of the magnetic levitation functional component. The steel plate positioning mechanism uses the functional component template as a positioning reference to fix the L-shaped steel plate on the functional component template, and is used to adjust and fix the position of the L-shaped steel plate in the magnetic levitation functional component to ensure the position accuracy of the sliding surface and the guide surface.

[0100] In some embodiments, reference Figure 6 The steel plate positioning mechanism includes at least two groups of steel plate positioning components arranged on the outside of the functional part template. The steel plate positioning components are distributed along the longitudinal direction of the functional part template. The steel plate positioning components include steel plate fixing members 36 that can press and fix the L-shaped steel plate on the functional part template at the corresponding position and steel plate adjusting members 37 that can adjust and support the L-shaped steel plate in the transverse direction at the corresponding position. The steel plate fixing members 36 and the steel plate adjusting members 37 are arranged on the side mold assembly, and an auxiliary support member 38 for providing support for the L-shaped steel plate is arranged on the side of the functional part template corresponding to the steel plate positioning member.

[0101] The steel plate fixing part 36 and the steel plate adjusting part 37 can be an adjusting screw or an electric support rod arranged on the side mold back 247. Taking the adjusting screw as an example, the adjusting screw is threadedly connected to the side mold back, and the adjusting screw is arranged horizontally with one end extending toward the L-shaped steel plate. Among them, the steel plate fixing part 36 is arranged at a position corresponding to the side edge of the functional part template, and the steel plate adjusting part 37 is arranged at a position above the steel plate fixing part.

[0102] Reference Figure 7 and Fig.10 The auxiliary support member 38 can be formed by two ear plates arranged on the side plate of one side of the functional component template, and the two ear plates provide support for the L-shaped steel plate.

[0103] During installation, the L-shaped steel plate is hoisted to the installation position, supported by auxiliary support parts, and the steel plate fixing parts are adjusted to fix the L-shaped steel plate to the side of the functional part template, and then the installation position of the L-shaped steel plate is detected. According to the detection results, the position of the L-shaped steel plate is adjusted by the steel plate adjusting parts until the L-shaped steel plate is adjusted to the set position. At this time, the steel plate adjusting parts can also play a role in supporting the L-shaped steel plate. The steel plate fixing parts and the steel plate adjusting parts can be used to position and adjust the L-shaped steel plate, and can prevent the L-shaped steel plate from moving during the concrete pouring and vibration process, thereby affecting the quality of the maglev track beam.

[0104] In some embodiments, the functional component positioning assembly includes a plurality of functional component templates 31 , and the functional component templates 31 are arranged in sequence along the longitudinal direction of the side templates, and each functional component template is used to position a group of magnetic levitation functional components.

[0105] In some embodiments, the molding system can also be applied to the casting molding of magnetic levitation space curved beams with different transverse slope angles.

[0106] In the forming system, the bottom mold assembly is arranged on the base 21, including a beam body bottom mold 221 and a support bottom mold 222 located at both ends of the beam body bottom mold. The support bottom mold 222 is configured to be able to rotate around the central axis of the upper end surface of the base, so that it can adapt to the forming requirements of the maglev track beam with different transverse slope angles by adjusting the inclination angle of the support bottom mold.

[0107] The side mold assembly includes two side mold plates 241 arranged opposite to each other, and the cross section of the side mold plates at the toe 13 position corresponding to the magnetic levitation track beam is an arc shape; the position corresponding to the toe position of the magnetic levitation track beam on the side mold plates is set to an arc shape, so that the support bottom mold can be rotated and adjusted to any desired inclination angle, such as Figure 4 and Fig.14 As shown; it is easy to think that the center of the arc part on the side template 241 coincides with the rotation center of the support bottom template, so that the support bottom template can always form a good fit with the side templates on both sides to ensure the molding quality of the maglev track beam.

[0108] The end mold assembly includes two end mold plates 251 arranged at both ends of the side mold assembly and two support end mold plates 26 located at both ends of the beam body bottom mold for molding the inner end surface of the support. The two end mold plates 251 are respectively arranged at both ends of the side mold plate 241. When closing the mold, the end-side closing mold method is adopted. A rubber strip and a gasket can be set at the joint position of the end mold plate and the side mold plate. By adjusting the thickness of the gasket, the angle between the end mold plate and the side mold plate can be adjusted.

[0109] The support end template 26 and the end template 251 are arranged opposite to each other, and are arranged between the beam body bottom template and the support bottom template. The support end template cooperates with the end template and the support bottom template to form the support part of the maglev track beam.

[0110] The forming system is configured to have a beam body bottom mold for forming the beam body and a support bottom mold for forming the support, and the support bottom mold is configured to be a rotatable structure so that it can be flexibly adjusted according to the forming requirements of the support bottom surface with different inclination angles, thereby forming a maglev track beam with different transverse slope angles; at the same time, in conjunction with the arc-shaped side mold plate, the forming of the maglev track beam with different transverse slope angles can be achieved through a set of forming system.

[0111] In some embodiments, an inner mold assembly 27 is further included, and the inner mold assembly 27 is arranged on the beam body bottom mold 221. The inner mold assembly is arranged according to the π-shaped structure of the beam body, and is used to form a beam body with a π-shaped structure during casting.

[0112] In some embodiments, reference Fig.14 The molding system further includes a bottom mold driving member 223. The support bottom mold 222 is connected to the base 21 via a rotating shaft. The bottom mold driving member 223 is used to drive the support bottom mold to rotate around the rotating shaft. The bottom mold driving member 223 includes two electric push rods respectively arranged on both sides of the rotating shaft. By controlling the two electric push rods, the tilt angle of the support bottom mold can be adjusted, and the two rotating electric push rods can be used to achieve stable support for the support bottom mold. The bottom mold driving member can realize the rotation adjustment of the support bottom mold within the range of ±12°.

[0113] In some embodiments, the molding system also includes two sets of side mold bases 242 arranged relatively to each other, and the side mold plates 241 are respectively arranged on the side mold bases 242 and are slidably connected with the side mold bases. A side mold driving component 243 is arranged between the side mold bases 242 and the side mold plates 241. The side mold driving component 243 is used to drive the side mold plate to move along the lateral direction of the maglev track beam to realize the closing and opening operations of the side mold plate.

[0114] In some embodiments, a slide rail 244 is provided on the side mold base 242, and the guide surface of the slide rail 244 is gradually inclined downward toward the outside in the transverse direction of the track beam. A slider 245 that cooperates with the slide rail is provided on the side mold plate 241, and the slider 245 is provided on the slide rail 244, so that when the slider moves on the slide rail in a direction away from the track beam, the side mold plate can move downward at the same time. The guide surface of the slide rail is set to an inclined structure, and when the side mold plate is demoulded, the side mold plate moves outward and downward at the same time, which can effectively prevent the interference between the functional component template 27 set on the side mold plate and the cast magnetic levitation track beam.

[0115] In some embodiments, reference Figure 3 and Fig.15 An end mold base 252 is respectively arranged at the position of the end mold plate 251. One end of the end mold plate 251 is arranged on the end mold base 252 and is connected with the end mold base 252 through a pivot sliding fit, so that the end mold plate can rotate around the pivot on the end mold base and slide in the horizontal direction on the end mold base.

[0116] The molding system further comprises an end mold driving assembly, which comprises a first end mold driving member 253 and a second end mold driving member 254, for driving the end mold plate to slide and rotate on the end mold base.

[0117] By setting the end template to be connected to the end template base through a pivot rotation and also able to slide on the end template base, during the demoulding operation, the end template can first move outward and separate from the end surface of the maglev track beam, and then flip the end template to achieve demoulding of the end template. Fig.15 This can solve the problem that the end template is easily interfered with the magnetic levitation track beam when opening the mold because the end template is provided with a hole template for forming the end face beam hole on the end face of the track beam.

[0118] In some embodiments, the first end mold driving member 253 is connected to the end mold plate 251 at a position close to the end mold base 252, and the second end mold driving member 254 is connected to the end mold plate 251 at a position away from the end mold plate base 252. In this way, when the end mold plate is demoulded, the first end mold driving member first drives the end mold plate to move horizontally outward to separate the end mold plate from the maglev track beam, and then the second end mold driving member flips the end mold plate.

[0119] End mold support bases 255 are respectively arranged on the outer sides of the end mold plates 251 for supporting the demoulding end mold plates.

[0120] Entrance channels 211 for convenient access are respectively arranged on both sides of the base 21 , so that operators can enter the forming system conveniently, thereby facilitating operations during the forming process of the track beam.

[0121] On the other hand, based on the maglev track beam forming system in the above embodiment, the present invention also provides a maglev space curved beam forming method, comprising the following steps:

[0122] Adjust the support bottom mold to the same angle as the bottom surface of the formed maglev track beam support;

[0126] Install the support end template, and then close the end templates at both ends;

[0127] After pouring is completed, the end templates at both ends are demoulded to both ends, the connection between the functional part template and the maglev functional part is removed, and the functional part template is demoulded, and then the side templates on both sides are slid to both sides to demould, and the formed maglev space curved beam is lifted out of the forming system.
