Description

Technical Field

[0001] The utility model relates to the technical field of magnetic levitation tracks, in particular to a positioning device in a magnetic module suspension slot. Background Art

[0002] The track beam is an important part of the maglev track. It is a beam or plate structure with a track functional surface, bearing the train load and transferring it to the supporting structure. In other words, the maglev track beam has the functions of both the beam and the track of a traditional railway. Compared with the operation of traditional rail trains, maglev trains have extremely high requirements for the accuracy of the track beam.

[0003] In the field of high-speed maglev, the distance between the train magnets and the magnets on the track beam directly affects the change in magnetic buoyancy. In order to ensure the smooth development of lift and resistance when the vehicle is floating and landing, and to ensure the driving comfort of the vehicle in the middle section of the line, very strict requirements are placed on the construction accuracy of the maglev track beam. For the track beam of the maglev track, it is generally equipped with a magnet module inside to provide forward driving force and lift required for suspension for the vehicle above. The magnet module and the track beam are installed through a connecting sleeve with an internal thread. Specifically, the connecting sleeve is embedded in the side wall of the track beam in advance. When the magnet module is installed later, the bolts connected to the magnet module are screwed into the corresponding connecting sleeve to achieve installation.

[0004] With the continuous in-depth research on ultra-high-speed maglev track technology, the application of ultra-high-speed maglev technology has gradually begun to be considered in some non-railway transportation fields, which requires the construction of test track sections for a large number of engineering tests and verifications. However, the magnet module of the traditional maglev track is too large and difficult to manufacture and install, which is not suitable for the use of ultra-high-speed maglev test track sections. Based on this, the applicant in this case has developed a new type of maglev track beam structure, which has a propulsion slot in the middle and suspension slots on both sides. By installing a maglev module in the propulsion slot to provide forward power for the train and a maglev module in the suspension slot to provide suspension lift for the train, the stable operation of high-speed maglev vehicles can be achieved.

[0005] With the continuous deepening of research and the implementation of relevant experiments, the applicant found that the lateral width of the middle propulsion slot of the test section's maglev track beam structure is relatively large, which can more conveniently complete the installation between the magnet module and the embedded sleeve; however, for the suspension slots on both sides, the lateral width is only 40 to 50 cm. Manually forcing the auxiliary installation into the slot has the problems of limited space and greater difficulty in operation, and there are also major safety hazards. Utility Model Content

[0006] The utility model provides a positioning device for a magnet module in a suspension slot, so as to solve the problem of great installation difficulty and potential safety hazards in the prior art when installing a corresponding magnet module in a suspension slot, and achieve the purpose of facilitating the installation of the magnet module in a relatively narrow suspension slot, reducing the installation difficulty and reducing the potential safety hazards in the operation.

[0007] The utility model is realized by the following technical solutions:

[0008] A positioning device in a magnet module suspension slot comprises a mounting plate for mounting on the top of the magnet module, a top plate detachably connected to the top of the mounting plate, and a back plate perpendicular to the top plate; the back plate is fixedly connected to the top plate and extends below the top plate; and also comprises a plurality of positioning holes provided on the back plate, wherein sleeve sensing devices are arranged in the positioning holes.

[0009] In view of the problem of great installation difficulty and safety hazards in installing the corresponding magnet module in the suspension groove in the prior art, the utility model proposes a positioning device for the magnet module in the suspension groove, wherein the top plate is used to be connected to the top surface of the mounting plate, and the back plate is used to be close to the side of the magnet module.

[0010] The mounting plate can be connected to the top of the magnet module to be installed by any existing mounting method, such as a common detachable connection method or a fixed connection method. The existence of the mounting plate can avoid 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 existence of the mounting plate is also convenient for lifting, and the magnet module can be lifted by lifting the mounting plate, so that the magnet module can be inserted into the corresponding suspension slot in a vertical state.

[0011] The present application uses a positioning hole and a sleeve sensing device located in the positioning hole to determine whether the sleeve required for installation is aligned. Specifically, in the process of gradually lowering into the suspension tank, the lateral position can be adjusted by a crane or other lifting machinery until each preset sleeve sensing device senses that there is a sleeve directly in front of it; when the mounting hole is directly opposite to 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 that what is in front is the surface of a prefabricated or cast-in-place rail beam. Therefore, the sleeve sensing device in the present application only needs to be able to identify whether the area directly in front and after passing through the mounting hole is a pre-buried sleeve or a rail beam surface, and can sense the pre-buried sleeve. The specific sensing method includes but is not limited to ranging, imaging or waveform judgment that can be achieved based on the existing technology.

[0012] It can be seen that the positioning system of the present application can solve the problem in the prior art that when installing the magnet module in the suspension slot of the maglev track beam, the staff is restricted by the narrow width of the suspension slot, which makes it difficult for the staff to enter the slot to assist in positioning and installation, and when forcibly squeezing into the slot to work, the space is limited and the operation is inconvenient, and there are great safety hazards; the positioning of the magnet module in the suspension slot of the present application can be completed on the ground outside the slot, and the staff does not need to enter the narrow slot to work, which significantly reduces the difficulty of the operation and improves the convenience and safety of installing the magnet module in the suspension slot.

[0013] Furthermore, a plurality of threaded blind holes are provided on the top surface of the mounting plate, and a plurality of threaded through holes matching the threaded blind holes are provided on the top plate. The depth of the threaded blind holes is less than the thickness of the mounting plate.

[0014] By aligning the threaded through holes on the top plate with the threaded blind holes on the top surface of the mounting plate one by one, and then screwing the matching bolts into them for tightening, a temporary connection between the positioning component and the mounting plate can be achieved; and after this installation method is in place, it is easy to remove and take out the corresponding bolts from the top, so that the positioning component can be removed and transported out separately without affecting the magnet module that has been in place, and the process of removing the positioning component is also completed on the ground outside the tank, which further reduces the safety hazards caused by workers entering the tank to work.

[0015] Furthermore, a support plate is arranged below the back plate, and the support plate is connected to the back plate via a telescopic device.

[0016] Furthermore, the support plate is perpendicular to the back plate, and the support plate and the top plate extend in the same side direction of the back plate.

[0017] The support plate extending on the same side as the top plate is used to support the magnet module from the bottom, thereby further improving the stability and safety of the magnet module during the lifting and installation of the magnet module, and further improving the integrity of the magnet module and the positioning assembly during the installation process. The support plate is perpendicular to the back plate, so the support plate and the top plate are parallel to each other.

[0018] In addition, considering that the heights of different magnet modules may be different, this solution connects the support plate and the back plate through a telescopic device, so that the user can flexibly adjust the height of the support plate according to the specific height of the magnet module, thereby ensuring that the support plate always supports the bottom end of the magnet module. The telescopic device in this solution can be implemented using any existing telescopic technology.

[0019] Furthermore, the telescopic device is a plurality of electric push rods, hydraulic cylinders or air cylinders.

[0020] Furthermore, the positioning hole passes through the back plate, so that the sleeve sensing device can be easily installed into the positioning hole from the side of the back plate away from the magnet module. After the magnet module and the positioning assembly have been connected, the sleeve sensing device can be flexibly replaced or maintained, avoiding the defect of having to completely remove the connection between the magnet module and the positioning assembly due to the failure of one or a few sleeve sensing devices, thereby improving the ease of use and working stability of the positioning system of the present application.

[0021] Furthermore, the hole wall of the positioning hole is provided with an internal thread; and also includes a mounting piece with an external thread matching the internal thread, and the sleeve sensing device is located on the mounting piece.

[0022] Since the positioning hole is a through hole, the present invention can screw the mounting piece into the positioning hole from the side of the back plate away from the magnet module, thereby facilitating flexible replacement or maintenance of the sleeve sensing device.

[0023] Furthermore, the mounting piece is screwed into the positioning hole from one end of the positioning hole away from the magnet module, and a limiting portion that cannot enter the positioning hole is provided at one end of the mounting piece away from the magnet module.

[0024] As the mounting piece is continuously screwed into the positioning hole, the sleeve sensing device can be sent into the positioning hole; when the limiting portion reaches the surface of the back plate, since the limiting portion cannot enter the positioning hole, it indicates that the mounting piece has been screwed into place and the sleeve sensing device has reached the set position, which can play a role in positioning the mounting piece.

[0025] The limiting portion in the present solution can adopt any achievable shape and structure, as long as it cannot enter the positioning hole.

[0026] Furthermore, the sleeve sensing device is arranged at one end of the mounting piece located inside the positioning hole.

[0027] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0028] 1. The utility model provides a positioning device for a magnet module in a suspension slot, which can solve the problem in the prior art that when installing a magnet module in a suspension slot of a maglev track beam, the narrow width of the suspension slot restricts workers from entering the slot for auxiliary positioning and installation, and when forcibly squeezing into the slot for operation, the space is limited and the operation is inconvenient, and there are great safety hazards.

[0029] 2. The utility model provides a device for positioning a magnet module in a suspension tank. The positioning of the magnet module in the suspension tank can be completed on the ground outside the tank. Workers do not need to enter the narrow tank to operate, which significantly reduces the difficulty of the operation and improves the convenience and safety of installing the magnet module in the suspension tank.

[0030] 3. The utility model provides a positioning device for a magnet module suspension tank, which is convenient for removing the device separately from the top without affecting the magnet module already in place. BRIEF DESCRIPTION OF THE DRAWINGS
