Description

A magnet module positioning system and method for maglev track beams in confined spaces Technical Field

[0001] This invention relates to the field of magnetic levitation track technology, specifically to a magnetic module positioning system and method for magnetic levitation track beams in confined spaces. Background Technology

[0002] The track beam is a crucial component of the maglev track, consisting of a beam or slab structure that functions as a track surface, bearing the train load and transferring it to the supporting structure. In other words, the maglev track beam performs the functions of both the beam and the track in a traditional railway. Compared to conventional rail train operation, maglev trains require extremely high precision from the track beam.

[0003] In the field of high-speed maglev, the distance between the train's magnets and the magnets on the track beam directly affects the change in maglev force. To ensure the smooth development of lift and drag during takeoff and landing, and to guarantee the ride comfort of the vehicle in the middle section of the line, extremely stringent requirements are placed on the construction precision of the maglev track beam. For the track beam of a maglev track, magnet modules are generally installed internally to provide forward driving force and the lift required for levitation of the vehicle above. The magnet modules are installed to the track beam through threaded connecting sleeves. Specifically, the connecting sleeves are pre-embedded in the side wall of the track beam, and during the later installation of the magnet modules, bolts connected to the magnet modules are screwed into the corresponding connecting sleeves to achieve installation.

[0004] With the deepening research into ultra-high-speed maglev track technology, its application is gradually being considered in some non-railway transportation fields. This necessitates the construction of test tracks for extensive engineering testing and verification. However, the magnet modules of traditional maglev tracks are too large and difficult to manufacture and install, making them unsuitable for use in ultra-high-speed maglev test tracks. Based on this, the applicant has developed a novel maglev track beam structure and filed a patent application on the same day as this application. This maglev track beam structure has a propulsion slot in the middle and suspension slots on both sides. By installing maglev modules in the propulsion slot to provide forward propulsion for the train and maglev modules in the suspension slots to provide levitation lift for the train, the stable operation of high-speed maglev vehicles can be ensured.

[0005] As the research deepened and related experiments were carried out, the applicant found that the lateral width of the middle propulsion trough of this test section maglev track beam structure was relatively large, which made it easier to complete the installation between the magnet module and the pre-embedded sleeve; however, the lateral width of the suspension troughs on both sides was only 40-50cm, and the difficulty of manually squeezing into the trough to assist in the installation was due to the limited space, and there were also significant safety hazards. Summary of the Invention

[0006] This invention provides a magnetic module positioning system and method for a maglev track beam in a narrow space, in order to solve the problem that there are great installation difficulties and safety hazards in installing the corresponding magnetic module in the suspension channel in the prior art. It realizes the purpose of facilitating the installation of magnetic modules in the relatively narrow suspension channel, reducing installation difficulty and reducing operational safety hazards.

[0007] This invention is achieved through the following technical solution:

[0008] A magnetic module positioning system for a maglev track beam in a confined space includes a magnetic module with several mounting holes, and a mounting plate fixedly connected to the top of the magnetic module; it also includes a positioning assembly detachably connected to the mounting plate, the positioning assembly including a top plate and a back plate perpendicular to each other, the top plate being used to abut against the top surface of the mounting plate, and the back plate being used to abut against the side of the magnetic module; it also includes several positioning holes formed on the back plate, the positioning holes corresponding one-to-one with the mounting holes, and a sleeve sensing device being installed in the positioning holes.

[0009] To address the significant installation difficulties and safety hazards associated with installing corresponding magnet modules within a levitation trough in existing technologies, this invention first proposes a magnet module positioning system for a maglev track beam in a confined space. Existing technology involves inserting a pre-embedded threaded sleeve into these mounting holes and screwing in bolts to tighten the magnet module. The positioning system of this application includes positioning components that match the magnet module, wherein a top plate abuts against the top surface of a mounting plate, and a back plate abuts against the side of the magnet module; those skilled in the art should understand that the side of the magnet module refers to the side wall of the magnet module facing away from the direction of the sleeve.

[0010] This application uses a mounting plate to connect the magnet module and the positioning component. The mounting plate is externally placed on the top of the magnet module, which avoids changing the existing structure of the magnet module in order to connect with the positioning component and can protect the top area of ​​the magnet module that is easily damaged. In addition, the presence of the mounting plate also facilitates the hoisting of the magnet module. The magnet module can be hoisted by hoisting the mounting plate, which makes it easy to insert the magnet module into the corresponding suspension slot in a vertical state.

[0011] This application uses positioning holes and sleeve sensing devices located within the positioning holes to determine whether the magnet module is aligned with the sleeve to be installed. Specifically, during the gradual lowering of the positioning component and the magnet module into the suspension trough, the lateral position of the positioning component and the magnet module can be adjusted using a crane or other lifting machinery until all the preset sleeve sensing devices detect a sleeve directly in front of them. When the mounting hole is aligned with the sleeve, the sleeve sensing device can sense the sleeve in front through the mounting hole; when the mounting hole is not aligned with the sleeve, the sleeve sensing device senses the surface of the precast or cast-in-place track beam. Therefore, the sleeve sensing device in this application only needs to be able to identify whether the area directly in front, after passing through the mounting hole, contains a pre-embedded sleeve or the surface of the track beam to achieve sensing of the pre-embedded sleeve. The specific sensing methods include, but are not limited to, ranging, imaging, or waveform judgment based on existing technologies.

[0012] As can be seen, the positioning system of this application can solve the problems in the prior art where, when installing magnet modules in the suspension trough of a maglev track beam, the narrow width of the suspension trough restricts the movement of workers into the trough for auxiliary positioning and installation, and the limited space for operation and significant safety hazards exist when forcibly squeezing into the trough. The positioning of the magnet module in the suspension trough can be completed on the ground outside the trough, eliminating the need for workers to enter the narrow trough, significantly reducing the difficulty of the operation and improving the convenience and safety of installing magnet modules in the suspension trough.

[0013] Furthermore, the top surface of the mounting plate has several threaded blind holes, and the top plate has several threaded through holes that match the threaded blind holes; the depth of the threaded blind holes is less than the thickness of the mounting plate.

[0014] This solution achieves a temporary connection between the positioning component and the mounting plate by aligning the threaded through holes on the top plate with the threaded blind holes on the top surface of the mounting plate, and then tightening them with matching bolts. Furthermore, this installation method allows for easy removal of the corresponding bolts from above after the magnet module is in place, facilitating the separate removal and transport of the positioning component without affecting the already positioned magnet module. The process of removing the positioning component is also completed on the ground outside the tank, further reducing the safety hazards caused by workers entering the tank.

[0015] Furthermore, a support plate is provided below the back panel, and the support plate is connected to the back panel by a telescopic device; the support plate is perpendicular to the back panel, and the support plate and the top plate extend in the same direction toward the back panel.

[0016] This design utilizes a support plate extending on the same side as the top plate to support the magnet module from the bottom, thereby improving the stability and safety of the magnet module during hoisting and installation, and also enhancing the overall integrity of the magnet module and positioning components during installation. The support plate is perpendicular to the back plate, thus parallel to the top plate.

[0017] Furthermore, considering the varying heights of different magnet modules, this solution uses a telescopic device to connect the support plate and the back plate. This allows users to flexibly adjust the support plate height according to the specific height of the magnet module, ensuring that the support plate always supports the bottom of the magnet module. The telescopic device in this solution can be implemented using any existing telescopic technology.

[0018] Furthermore, the positioning hole penetrates the back plate, facilitating the insertion of the sleeve sensing device from the side of the back plate away from the magnet module. This allows for flexible replacement or maintenance of the sleeve sensing device after the magnet module and positioning assembly have been connected, avoiding the need to completely disconnect the magnet module and positioning assembly due to the failure of one or a few sleeve sensing devices. This improves the ease of use and operational stability of the positioning system of this application.

[0019] Furthermore, the positioning hole has an internal thread on its wall; it also includes a mounting component with an external thread that matches the internal thread, the mounting component being screwed into the positioning hole from the end of the positioning hole away from the magnet module, and a limiting part being provided at the end of the mounting component away from the magnet module; the sleeve sensing device is located at the end of the mounting component located inside the positioning hole, and the limiting part cannot enter the positioning hole.

[0020] Because the positioning hole is a through hole, this design allows the mounting component to be screwed into the positioning hole from the side of the backplate away from the magnet module, facilitating flexible replacement or maintenance of the sleeve sensing device. As the mounting component is continuously screwed into the positioning hole, the sleeve sensing device can be pushed into the positioning hole; when the limiting part reaches the surface of the backplate, since the limiting part cannot enter the positioning hole, it indicates that the mounting component has been screwed into place and the sleeve sensing device has reached the set position, thus achieving the positioning function of the mounting component.

[0021] The limiting part in this solution can adopt any feasible shape and structure, as long as it cannot enter the positioning hole.

[0022] Furthermore, the top plate and the back plate are integrally formed to ensure the integrity of the positioning components and prevent the back plate from falling off during the hoisting of the top plate; the top of the top plate is provided with a hoisting lug assembly for hoisting, which facilitates the hoisting operation during the specific use of this application and further improves construction efficiency.

[0023] Furthermore, it also includes a bolt positioning assembly, which includes an L-shaped tube body comprising a long tube and a short tube that are perpendicular to each other and connected. A turntable is rotatably connected inside the short tube, and a bolt positioning protrusion is provided on the side surface of the turntable facing the open end of the short tube. It also includes a drive mechanism for driving the turntable to rotate, and the input end of the drive mechanism extends from the open end of the long tube.

[0024] This application enables the pre-set sleeves on the track beam to enter their corresponding mounting holes, thus completing the positioning of the magnet module and the track beam suspension trough wall. However, at this point, the magnet module and the track beam are still not connected. Due to the limitation of the suspension trough width, it is also inconvenient for workers to enter the suspension trough to install the corresponding bolts. Furthermore, since the maximum depth of the suspension trough can be more than one meter, for sleeves located at higher positions in the suspension trough, workers can also extend their arms into the trough from above to install bolts. However, for sleeves located at lower positions in the suspension trough, the difficulty of installing bolts is much greater. This makes on-site operations very difficult, usually requiring relatively slender workers to extend their upper bodies into the trough to complete the operation, which also has the drawbacks of high operational difficulty and high safety hazards.

[0025] To overcome this problem, this solution proposes a dedicated bolt positioning assembly, which consists of an L-shaped tube composed of a long tube and a short tube. The long tube is used to extend from the slot opening to a deeper position inside the suspension tank. The thread to be installed is inserted from the end of the short tube, and the bolt engages with the bolt positioning protrusion on the surface of the turntable, so that the bolt can rotate synchronously with the turntable.

[0026] This solution uses a bolt positioning assembly to insert bolts into a deeper part of the suspension tank from the outside. Then, the input end of the drive mechanism outside the suspension tank drives the turntable to rotate, which in turn drives the bolt to rotate and simultaneously feeds the bolt towards the sleeve. This achieves bolt fixation of the sleeve located at a lower position in the suspension tank. This process does not require workers to put their upper bodies into the tank, which significantly reduces the difficulty of fixing the magnet module and reduces safety hazards during operation.

[0027] It should be noted that the bolts used in this design to screw into the mounting holes and sleeves must have grooves at their ends that match the bolt positioning protrusions. This ensures that the turntable and bolts are relatively fixed and rotate synchronously in the circumferential direction. Furthermore, the input end of the drive mechanism is the end used to control the operation of the drive mechanism. It can be a mechanical component or handle, or an electrically controlled button or switch.

[0028] Furthermore, the drive mechanism includes a first drive shaft coaxial with and fixedly connected to the turntable, a first bevel gear fixed on the first drive shaft, a second bevel gear meshing with the first bevel gear, a second drive shaft coaxial with and fixedly connected to the second bevel gear, and a handle fixedly connected to the second drive shaft; the second drive shaft extends out from the open end of the long tube, and the handle is located outside the long tube.

[0029] In practical use, the operator only needs to turn the handle in the specified direction outside the suspension tank to drive the second drive shaft to rotate. Then, the two meshing bevel gears reverse the direction and drive the first drive shaft to rotate, ultimately driving the turntable to rotate.

[0030] This application also proposes a method for positioning the magnet module of a maglev track beam in a narrow space, including the following steps:

[0031] Connect the top plate to the mounting plate in the positioning assembly, so that the back plate in the positioning assembly is against the side of the magnet module facing away from the sleeve.

[0032] The lifting and positioning assembly is used to simultaneously lift and transport the magnet module into the trench where the magnet module is to be installed.

[0033] The positioning components and magnet modules are gradually lowered, and the lateral position of the positioning components and magnet modules is adjusted by the crane boom until each of the preset sleeve sensing devices senses that there is a sleeve in front of it.

[0034] Keeping the height of the positioning component and the magnet module constant, push the positioning component and the magnet module together in the direction of the sleeve so that each sleeve enters the corresponding mounting hole;

[0035] Disconnect the top plate from the mounting plate and lift the positioning component out of the trench;

[0036] Screw bolts that match the sleeve into each mounting hole.

[0037] Furthermore, the step of screwing bolts that match the sleeve into each mounting hole includes:

[0038] Position the bolt with the nut on the turntable inside the bolt positioning assembly;

[0039] The bolt positioning assembly extends downward from the top of the groove, aligning the bolt with a mounting hole;

[0040] The lateral movement of the bolt positioning assembly gradually feeds the bolt into the mounting hole, while the drive mechanism drives the turntable to rotate.

[0041] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0042] 1. The present invention provides a magnetic module positioning system and method for a maglev track beam in a narrow space, which can solve the problems in the prior art where, when installing a magnetic module in the suspension trough of a maglev track beam, the narrow width of the suspension trough restricts the workers from entering the trough to assist in positioning and installation, and when forcibly squeezing into the trough to work, the limited space for operation is inconvenient and there are significant safety hazards.

[0043] 2. The present invention provides a magnetic module positioning system and method for a maglev track beam in a narrow space. The positioning of the magnetic module in the suspension trough can be completed on the ground outside the trough, and the workers do not need to enter the narrow trough to work. This significantly reduces the difficulty of the operation and improves the convenience and safety of installing the magnetic module in the suspension trough.

[0044] 3. The present invention provides a magnetic module positioning system and method for a maglev track beam in a narrow space, which can realize the temporary connection between the positioning component and the mounting plate, and facilitate the individual removal of the positioning component from above without affecting the already positioned magnetic module. Furthermore, the process of removing the positioning component is also completed on the ground outside the channel, which further reduces the safety hazards caused by workers entering the channel to work.

[0045] 4. The present invention provides a magnetic module positioning system and method for a magnetic levitation track beam in a narrow space, which can flexibly adjust the height of the support plate according to the specific height of the magnetic module, thereby ensuring that the support plate always supports the bottom of the magnetic module, and improving the versatility of this application.

[0046] 5. The present invention provides a magnetic module positioning system and method for a maglev track beam in a narrow space. This system facilitates the insertion of a sleeve sensing device into the positioning hole from the side of the back plate away from the magnetic module. Furthermore, after the magnetic module and the positioning assembly have been connected, the sleeve sensing device can be flexibly replaced or maintained. This avoids the defect of having to completely disconnect the connection between the magnetic module and the positioning assembly due to the failure of one or a few sleeve sensing devices, thereby improving the ease of use and operational stability of the positioning system of this application.

[0047] 6. The present invention provides a magnetic module positioning system and method for a maglev track beam in a narrow space. Through a dedicated bolt positioning assembly, bolts can be driven into a deeper position in the suspension trough from the outside. Then, the turntable is driven to rotate from the outside of the suspension trough through the input end of the drive mechanism, thereby driving the bolt to rotate and simultaneously sending the bolt into the sleeve direction. This achieves bolt fixing of the sleeve located at a lower position in the suspension trough. This process does not require the operator to put their upper body into the trough, which significantly reduces the difficulty of fixing the magnetic module and reduces safety hazards during operation.

The bolt positioning assembly includes an L-shaped tube body, which includes a long tube 201 and a short tube 202 that are perpendicular to each other and connected. A turntable 203 is rotatably connected inside the short tube 202. A bolt positioning protrusion 204 is provided on the surface of the turntable 203 facing the open end of the short tube 202. The system also includes a drive mechanism for driving the turntable 203 to rotate, and the input end of the drive mechanism extends from the open end of the long tube 201.

[0078] Example 3:

[0079] A method for locating the magnet module of a maglev track beam in a confined space, based on the positioning system in Embodiment 1 or 2, includes the following steps:

[0080] S1. Connect the top plate 103 to the mounting plate 102 in the positioning assembly, so that the back plate 104 in the positioning assembly abuts against the side of the magnet module 101 away from the direction of the sleeve.

[0081] S2. Lifting and positioning assembly: synchronously lifts the magnet module 101 into the groove where the magnet module 101 is to be installed;

[0082] S3. Gradually lower the positioning component and the magnet module 101, and adjust the lateral position of the positioning component and the magnet module 101 by the crane swing arm until each of the preset sleeve sensing devices 106 senses that there is a sleeve in front of it.

[0083] S4. Keeping the height of the positioning component and the magnet module 101 unchanged, push the positioning component and the magnet module 101 as a whole towards the direction of the sleeve, so that each sleeve enters the corresponding mounting hole 100.

[0084] S5. Disconnect the top plate 103 from the mounting plate 102 and lift the positioning component out of the trench;

[0085] S6. Screw bolts that match the sleeve into each mounting hole 100; specifically, this may include:

[0087] S602. Insert the bolt positioning assembly downward from the top of the groove so that the bolt is aligned with a mounting hole 100;

[0088] S603, the lateral movement bolt positioning assembly gradually feeds the bolt into the mounting hole 100, while simultaneously rotating the handle 209 to drive the turntable 203 to rotate in the direction of the bolt being fastened.

[0089] More preferably, it also includes:

[0090] S604. When the handle 209 cannot be turned, it indicates that the bolt has been tightened in place. At this time, the bolt positioning assembly is pulled back laterally as a whole, so that the bolt positioning protrusion 204 is disengaged from the bolt. After the short tube 202 is completely disengaged from the area where the bolt is located, the bolt positioning assembly is lifted.

[0091] S605. Return to step S601 and install the next bolt; continue until all mounting holes 100 are screwed into bolts.

[0092] Example 4:

[0093] A magnetic module positioning system for a maglev track beam in a confined space, based on any of the above embodiments, shows the track beam with the magnetic module 101 positioned and installed as shown in Figures 4 and 5, including a lower foundation 29 and a beam-rail assembly located on the lower foundation 29. Those skilled in the art should understand that the dashed lines in Figures 4 and 5 are schematic lines used to separate the lower foundation 29 from the beam-rail assembly and do not represent any entity or meaning.

[0094] The beam-rail assembly in this embodiment includes a propulsion groove 30 and a suspension groove 31 located on both sides of the propulsion groove 30. The suspension groove 31 is parallel to the axis of the propulsion groove 30. The propulsion groove 30 is used to install the propulsion magnet module, and the suspension groove 31 is used to install the suspension magnet module.

[0095] The beam-rail assembly also includes two first concrete components 33 and two second concrete components 34 located between the two first concrete components 33; the two second concrete components 34 form a propulsion groove 30, and the first concrete components 33 and the second concrete components 34 located on the same side of the propulsion groove 30 form a suspension groove 31.

[0096] The two first concrete components 33 and the two second concrete components 34 are symmetrically distributed with respect to the axis of the propulsion groove 30; the transverse outer wall of the first concrete component 33 is coplanar with the transverse outer wall of the lower foundation 29; the transverse inner wall of the second concrete component 34 is coplanar with the groove wall of the propulsion groove 30.

[0097] The top of the second concrete member 34 is set in a stepped shape that gradually decreases in the lateral outward direction.

[0098] The bottom of the suspension tank 31 is a widening area 35, the top of the widening area 35 is connected to the bottom of the suspension tank 31, and the widening area 35 includes a widening part whose lateral width gradually increases from top to bottom.

[0099] A deep groove 32 is formed on the top surface of the lower foundation 29. The long axis of the deep groove 32 is parallel to the axis of the propulsion groove 30, and the top of the deep groove 32 is connected to the bottom of the propulsion groove 30. The two transverse side walls of the deep groove 32 are coplanar with the inner side walls of the two second concrete components 34, respectively.

[0100] The bottom of the deepening groove 32 is provided with several first through holes 36 distributed along the axial direction, and the bottom of the suspension groove 31 is provided with several second through holes 37 distributed along the axial direction.

[0101] Several sleeves 28 can also be pre-embedded on the inner side wall of the first concrete component 33 and the inner and outer side walls of the second concrete component 34 for subsequent installation and use of the magnet module.

[0102] The track beam structure in this embodiment is fabricated using a cast-in-place process, including the following steps:

[0103] Excavate the track beam foundation pit, position and install two side formwork pieces inside the pit, leaving space in the foundation pit at both ends of the side formwork axially;

[0104] Install a lower module that matches the lower foundation 29 between the two side molds;

[0105] Grout is injected into the lower module. After the concrete has initially set, the lower module is demolded to obtain the lower foundation 29.

[0106] Between the two side formworks and above the lower foundation 29, an upper module matching the beam-rail assembly is installed;

[0107] Grout the upper module and demold the upper module after the concrete has initially set.

[0108] Backfilling of the foundation pit.

[0109] The cast-in-place molding method in this embodiment first pours the internal space of the lower module, which can first form the overall structure of the bottom foundation of the maglev track beam. After ensuring the stability of the load-bearing capacity, the upper module is then installed and poured. This allows the load-bearing area and the track area of ​​the maglev track beam to be formed independently but are mutually fixed and dependent. This can reduce the risks of mutual interference, concrete delamination or layering that may occur when the load-bearing area and the track area of ​​the maglev track beam are poured in place at the same time, while also satisfying the integrity of the maglev track beam. Furthermore, it allows the high-height maglev track beam to be poured in stages on the work site, overcoming the defects such as the difficulty of cast-in-place operation and severe formwork deformation caused by the large overall height of the maglev track beam.

[0110] Preferably, the lower module is shown in Figures 6 to 9:

[0111] It includes a lower end mold 2 that is detachably connected to both ends of the two side molds 1, two base partition molds 3 located between the two side molds 1, and a first L-shaped mold 4 fixed to the top of the base partition mold 3. The base partition mold 3 has several channels 27 with open bottoms, and the base partition mold 3 is parallel to the side molds 1. The first L-shaped mold 4 extends to the lateral outer direction of the corresponding base partition mold 3.

[0112] The lower module also includes a first occupant cylinder 7 fixedly connected between two base partition molds 3. Several first occupant cylinders 7 are evenly distributed along the axial direction between the two base partition molds 3. The first occupant cylinders 7 are at the same height as the base partition molds 3, and the top height of the first occupant cylinders 7 is lower than the top height of the first L-shaped mold 4.

[0113] The lower module also includes a second spacer cylinder 8 located between the base spacer 3 and the side mold 1 on the same side, and the second spacer cylinder 8 is at the same height as the first L-shaped mold 4.

[0114] The top of the second locating cylinder 8 is provided with a first positioning protrusion 9, and the top of the first L-shaped mold 4 is provided with a second positioning protrusion 10 that corresponds one-to-one with the first positioning protrusion 9; the first positioning protrusion 9 and the second positioning protrusion 10 are provided with matching first threaded through holes, and the first positioning protrusion 9 and the second positioning protrusion 10 are connected by bolts 11.

[0115] The lower module also includes an internal top mold 12 for placement at the top of the base partition mold 3 and between the two first L-shaped molds 4, and a lower top mold 13 for placement at the top of the first L-shaped mold 4 and / or the second occupier 8; the lower top mold 13 has several first through slots 14 for the first positioning protrusion 9 to pass through and second through slots 15 for the second positioning protrusion 10 to pass through; the width of the first through slot 14 is equal to the width of the first positioning protrusion 9, the width of the second through slot 15 is equal to the width of the second positioning protrusion 10, and the major axes of the first through slot 14 and the second through slot 15 are perpendicular to the axial direction of the side mold 1; the lower top mold 13 also has at least two diagonally distributed grouting holes 16.

[0116] The internal top mold 12 can be temporarily installed on the first L-shaped mold 4 through any detachable connection method such as snap-fit ​​or tenon joint.

[0117] In a more preferred embodiment, a bottom mold can also be set between the two side molds 1 according to actual operational needs.

[0118] This embodiment can limit the second occupant cylinder by using the base partition mold and the first L-shaped mold, thereby ensuring the rapid positioning and installation of the second occupant cylinder, while avoiding the shaking or displacement of the second occupant cylinders during the pouring process; it can also flexibly adjust the lateral relative position of the second occupant cylinder and the base partition mold before pouring, thus further expanding the versatility of this application.

[0119] The relative position of the second occupant tube and the foundation partition mold can be determined by the positions of the first and second positioning protrusions. This allows for a final check of the position of each second occupant tube before casting, effective adjustment of the relative position of the second occupant tube and the foundation partition mold, and installation of corresponding bolts on the top mold. The presence of bolts will not affect the shape of the lower structure of the maglev track beam after casting.

[0120] In this embodiment, the method for installing a lower module that matches the lower foundation 29 between the two side molds includes:

[0121] Several first occupier cylinders 7 are connected to a base partition mold 3, and another base partition mold 3 is connected;

[0122] The two basic partition molds 3, together with several first occupant cylinders 7 in between, are hoisted to the space between the two side molds 1, so that the two basic partition molds 3 are in the designed position.

[0123] Place each of the second occupier cylinders 8 in the designed position, so that the first positioning protrusion 9 on each of the second occupier cylinders 8 is directly aligned with the second positioning protrusion 10 on the corresponding first L-shaped mold 4;

[0124] Install the inner top mold 12 between the two first L-shaped molds 4, so that the two lateral ends of the inner top mold 12 are respectively located on the stepped surfaces of the two first L-shaped molds 4;

[0125] Install the lower ejector mold 13, place the lower ejector mold 13 on the top of the first L-shaped mold 4 and the second occupier cylinder 8, and make the first positioning protrusion 9 pass through the corresponding first through groove 14 and the second positioning protrusion 10 pass through the corresponding second through groove 15.

[0126] By checking the positions of the first positioning protrusion 9 and the second positioning protrusion 10 on the lower die 13, the relative positions of each second occupier 8 and the first L-shaped die 4 are verified. If the lateral error of a certain second occupier 8 is found to exceed the threshold, force is applied to the first positioning protrusion 9 to drive the corresponding second occupier 8 to adjust its lateral position.

[0127] After all the positions of the second locating cylinders 8 have been verified, the bolts 11 are screwed into the corresponding first threaded through holes and locked with nuts on the outer side of the first positioning protrusion 9 and the second positioning protrusion 10.

[0128] The upper module in this embodiment is shown in Figures 10 and 11:

[0129] It includes an upper end mold that is detachably connected to both ends of the two side molds 1 along the axial direction, two propulsion groove molds 5 located between the two side molds 1, a first suspension groove mold 6 located between the propulsion groove mold 5 and the side mold 1 on the same side, and a second suspension groove mold 17; the propulsion groove mold 5, the first suspension groove mold 6 and the second suspension groove mold 17 are all parallel to the side molds 1.

[0130] The bottom of the first suspension trough mold 6 and the second suspension trough mold 17 are both connected to the inclined mold 18. The bottom of the inclined mold 18 is connected to the bearing mold 19. The inclined mold 18 is inclined from top to bottom in the lateral outward direction. The bearing mold 19 is parallel to the corresponding first suspension trough mold 6 or second suspension trough mold 17.

[0131] The first suspension trough mold 6 and the second suspension trough mold 17 each have several axially distributed insertion holes 25 at their bottom sides. The top of the inclined mold 18 is provided with several positioning blocks 20 that correspond one-to-one with the insertion holes 25. The first suspension trough mold 6 and the second suspension trough mold 17 have second threaded through holes 21 on their two axially oriented end faces, and the second threaded through holes 21 communicate with the nearest insertion hole 25. The positioning blocks 20 at both ends along the axial direction have threaded blind holes 22 that match the second threaded through holes 21. The mold also includes a gripping part 23 provided on the inner sidewall of the first suspension trough mold 6 and the second suspension trough mold 17, and several sleeve mounting holes 24 provided on the surface of the first suspension trough mold 6 and the second suspension trough mold 17.

[0132] The second suspension channel mold 17 is located between the corresponding first suspension channel mold 6 and propulsion channel mold 5. The top of the second suspension channel mold 17 is fixedly connected to the second L-shaped mold 26. The second L-shaped mold 26 extends toward the direction of the propulsion channel mold 5, and the top height of the second L-shaped mold 26 is higher than the top height of the side mold 1 and the first suspension channel mold 6, but lower than the top height of the propulsion channel mold 5.

[0133] In this embodiment, all templates can be heightened and lengthened, facilitating external connection and stabilization through common support or tie-down methods.

[0134] In a more preferred embodiment, all templates in the upper module, as well as the side mold 1 and the lower top mold 13, are made of steel templates; all templates in the lower module, except for the lower top mold 13, are made of wood templates.

[0135] In a more preferred embodiment, each sleeve mounting hole 24 is fitted with a sleeve 28, which is left inside the molded component during demolding.

[0136] In this embodiment, the method for demolding the upper module includes:

[0137] After the concrete inside the upper module has initially set, the workers enter the remaining foundation pit space at both ends of the axis and unscrew the bolts connecting the second threaded through hole 21 and the threaded blind hole 22.

[0138] By pulling the first suspension tank mold 6 and the second suspension tank mold 17 towards the inside of the already formed suspension tank through the gripping part 23, the first suspension tank mold 6 and the second suspension tank mold 17 are demolded.

[0139] The first suspension tank mold 6 and the second suspension tank mold 17 are respectively lifted out from the already formed suspension tank;

[0140] The entire assembly consisting of each inclined mold 18 and the bearing mold 19 is demolded and lifted out of the formed suspension trough.

[0141] This embodiment eliminates the need for excavating an extra foundation pit of equal length to the side plate, enabling rapid demolding of irregularly shaped upper modules. This effectively solves the problems of difficult demolding and difficulty in removing inclined molds, while also effectively reducing the risk of damage to the sleeve caused by bumps or squeezing.
