Description

Technical Field

[0001] This utility model relates to the field of maglev train technology, and in particular to a reader mounting structure for an absolute positioning device of a maglev train. Background Technology

[0002] Maglev trains are a new type of transportation that uses electromagnetic force to levitate, guide, and traction vehicles. During operation, the maglev train levitates above the track without contacting it. It features high speed, strong climbing ability, small turning radius, low noise, and no wear. Due to the high speed, lack of contact with the track, and short distance between the train undercarriage and the track, traditional speed measurement and positioning methods for wheel-rail trains are not suitable for high-speed maglev trains. To address the inapplicability of traditional speed measurement and positioning methods, an absolute positioning device for high-speed maglev trains based on RFID is proposed.

[0003] Traditional maglev train absolute positioning device reader installation structures often require complex mechanical structures on the track or train to fix the reader and precisely align it with positioning marks or sensors. These mechanical structures not only increase installation complexity but can also lead to a decrease in positioning accuracy, as even minor installation errors can affect the final positioning result. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of not being able to install the reader. To this end, we propose a reader installation structure for the absolute positioning device of a maglev train.

[0005] To achieve the above objectives, this application adopts the following technical solution: a reader mounting structure for an absolute positioning device of a maglev train, comprising a base plate, a mounting column fixedly connected to the top of the base plate, a rotating column rotatably connected inside the mounting column, a reader body disposed inside the rotating column, adjustment grooves provided at both ends of the rotating column, a push block slidably connected inside the adjustment groove, a through hole provided on the side of the adjustment groove away from the push block, an insertion rod fixedly connected on the side of the push block near the reader body, insertion holes provided at both ends of the reader body, and arc-shaped blocks fixedly connected at both ends of the inner wall of the base plate.

[0006] Preferably, the size of the insertion rod is adapted to the size of the insertion hole, and the surface of the insertion rod is slidably connected to the interior of the insertion hole.

[0007] Preferably, sliding grooves are provided on both sides of the adjustment groove, and sliders are fixedly connected to both sides of the push block, with the surface of the sliders slidably connected to the inside of the sliding groove.

[0008] Preferably, a storage spring is fixedly connected to the side of the push block near the inside of the adjustment groove, and the side of the storage spring away from the push block is fixedly connected to the inside of the adjustment groove.

[0009] Preferably, a rubber pad is provided at the bottom of the interior of the mounting column.

[0010] Preferably, annular grooves are provided at both ends of the rotating column surface, and annular blocks are fixedly connected to both ends of the inner wall of the base plate.

[0011] Preferably, both ends of the mounting column are provided with threaded rods, and both ends of the rotating column are provided with threaded grooves.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operator inserts the reader body into the rotating column, aligns the insertion rod with the insertion hole, and rotates the rotating column to move the push block and the insertion rod. When the push block contacts the thicker end of the arc-shaped block, the arc-shaped block squeezes the push block to move, and drives the insertion rod to be inserted into the insertion hole for fixation, thereby achieving the installation function.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1- Figure 5 As shown, this utility model provides a technical solution: a reader installation structure for an absolute positioning device of a maglev train, including a base plate 1, a mounting column 2 fixedly connected to the top of the base plate 1, a rotating column 3 rotatably connected inside the mounting column 2, a reader body 4 disposed inside the rotating column 3, adjustment grooves 5 opened at both ends of the rotating column 3, a push block 6 slidably connected inside the adjustment groove 5, a through hole 14 opened on the side of the adjustment groove 5 away from the push block 6, an insertion rod 7 fixedly connected to the side of the push block 6 near the reader body 4, insertion holes 8 opened at both ends of the reader body 4, and arc-shaped blocks 9 fixedly connected to both ends of the inner wall of the base plate 1. The operator inserts the reader body 4 into the interior of the rotating column 3, aligns the insertion rod 7 with the insertion hole 8, and rotates the rotating column 3 to move the push block 6 and the insertion rod 7. When the push block 6 contacts the thicker end of the arc-shaped block 9, the arc-shaped block 9 squeezes the push block 6 to move, and drives the insertion rod 7 to insert into the insertion hole 8 for fixation, thereby achieving the installation function.

[0022] Reference Figure 1 - Figure 5 As shown in this embodiment: the size of the insertion rod 7 is adapted to the size of the insertion hole 8, and the surface of the insertion rod 7 is slidably connected to the inside of the insertion hole 8. By adapting the size of the insertion rod 7 to the size of the insertion hole 8, the smooth movement of the insertion rod 7 inside the insertion hole 8 can be ensured, thereby improving the operating efficiency of the entire device. In addition, the high fitting precision between the insertion rod 7 and the insertion hole 8 can effectively reduce mechanical wear and extend the service life of the equipment.

[0023] Reference Figure 3 As shown in this embodiment: sliding grooves 10 are provided on both sides of the inner side of the adjusting groove 5, and sliders 11 are fixedly connected to both sides of the push block 6. The surface of the slider 11 is slidably connected to the inside of the sliding groove 10. When the operator moves the push block 6, the push block 6 drives the slider 11 to slide inside the sliding groove 10. Through the above settings, precise positioning and control can be achieved. This design not only improves the accuracy of operation, but also reduces the additional friction caused by the imprecise fit between mechanical parts, thereby reducing energy consumption. In addition, the through hole 14 provides an additional support point for the push block 6, which helps to disperse the stress concentration that may be generated during the movement of the push block 6, further enhancing the stability and durability of the device.

[0024] Reference Figure 3As shown in this embodiment: a storage spring 12 is fixedly connected to the side of the push block 6 near the inside of the adjustment groove 5, and the side of the storage spring 12 away from the push block 6 is fixedly connected to the inside of the adjustment groove 5. When the operator moves the push block 6 into the inside of the adjustment groove 5, the push block 6 compresses the storage spring 12 to store force, and the insertion rod 7 is inserted into the insertion hole 8 to fix the reader body 4. When the operator releases the contact between the push block 6 and the arc block 9, the push block 6 drives the insertion rod 7 to release the limit between it and the insertion hole 8 under the action of the rebound force of the storage spring 12.

[0025] Reference Figure 3 As shown in this embodiment, a rubber pad 13 is provided at the bottom of the mounting column 2. By providing a rubber pad 13 at the bottom of the mounting column 2, the vibration generated during the operation of the equipment can be effectively absorbed, reducing the impact on the surrounding environment. In addition, the use of the rubber pad 13 can also protect the bottom of the equipment from scratches or impacts by hard objects, extending the service life of the equipment.

[0026] Reference Figure 3 and Figure 4 As shown in this embodiment: both ends of the rotating column 3 are provided with annular grooves 15, and both ends of the inner wall of the bottom plate 1 are fixedly connected with annular blocks 16. When the operator rotates the rotating column 3, the rotating column 3 rotates along the trajectory of the annular blocks 16. Through the above settings, the stability of the rotating column 3 during the rotation process can be ensured, and equipment damage caused by uneven rotation can be avoided. In addition, the setting of the annular grooves 15 allows the rotating column 3 to fit tightly with the annular blocks 16 during rotation, reducing the gap during the rotation process, thereby improving the operating efficiency of the equipment.

[0027] Reference Figure 2 and Figure 4 As shown in this embodiment: threaded rods 17 are provided at both ends of the mounting post 2, and threaded grooves 18 are provided at both ends of the rotating post 3. In order to avoid unstable contact between the push block 6 and the arc block 9 after the operator installs the reader body 4, the operator rotates the threaded rod 17 into the threaded groove 18 to fix the positions of the mounting post 2 and the rotating post 3 to each other, so as to avoid unstable positioning of the insertion rod 7 and the insertion hole 8.

[0028] Working principle: The operator inserts the reader body 4 into the rotating column 3, aligning the insertion rod 7 with the insertion hole 8. Rotating the rotating column 3 moves the push block 6 and the insertion rod 7. When the push block 6 contacts the thicker end of the arc-shaped block 9, the arc-shaped block 9 presses against the push block 6, causing it to move and insert the insertion rod 7 into the insertion hole 8 for fixation, thus achieving the installation function. The matching size of the insertion rod 7 with the insertion hole 8 ensures smooth movement of the insertion rod 7 within the insertion hole 8, thereby improving the overall operating efficiency of the device. Furthermore, the high precision of the fit between the insertion rod 7 and the insertion hole 8 effectively reduces mechanical wear and extends the lifespan of the device. To extend the equipment's lifespan, when the operator moves the push block 6, the push block 6 drives the slider 11 to slide inside the slide groove 10. This design enables precise positioning and control, improving operational accuracy and reducing additional friction caused by imprecise fit between mechanical parts, thus lowering energy consumption. Furthermore, the through hole 14 provides an additional support point for the push block 6, helping to disperse stress concentration that may occur during movement, further enhancing the device's stability and durability. When the operator moves the push block 6 into the adjusting groove 5, the push block 6... The compression spring 12 is compressed to store energy, causing the insertion rod 7 to be inserted into the socket 8 to fix the reader body 4. When the operator releases the contact between the push block 6 and the arc block 9, the rebound force of the compression spring 12 causes the push block 6 to move the insertion rod 7 out of the limiting position between it and the socket 8. The rubber pad 13 at the bottom of the mounting column 2 can effectively absorb the vibration generated during the operation of the equipment, reducing the impact on the surrounding environment. In addition, the use of the rubber pad 13 can also protect the bottom of the equipment from scratches or impacts by hard objects, extending the service life of the equipment. When the operator rotates the rotating column 3, the rotating column 3 moves along... The annular block 16 rotates along its trajectory. This design ensures the stability of the rotating column 3 during rotation, preventing equipment damage caused by uneven rotation. Furthermore, the annular groove 15 allows the rotating column 3 to fit tightly with the annular block 16 during rotation, reducing gaps and improving equipment operating efficiency. To prevent unstable contact between the push block 6 and the arc-shaped block 9 after the reader body 4 is installed, the threaded rod 17 is inserted into the threaded groove 18 to fix the positions of the mounting column 2 and the rotating column 3, preventing unstable positioning of the insertion rod 7 and the insertion hole 8.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
