Description
Technical Field
The utility model relates to a track traffic technical field, concretely relates to well low-speed magnetism floats periodic tooth's socket structure and presses down switch roof beam that shakes.
Background
There are two commercial operation' S medium and low speed magnetic levitation circuit in China, beijing S1 line and Changsha fast line, and the switch beam structure of these two lines all has the technical problem that has not solved at present: when the system and the magnetic levitation vehicle form a system and complete the coupling movement between the system and the magnetic levitation vehicle, the speed measurement interference occurs at the Beijing S1 turnout, the emergency brake phenomenon occurs on the turnout beam of the magnetic levitation vehicle, and the problem that a cover plate with the thickness of 5mm is added is alleviated to some extent but not completely solved; the turnout coupling resonance occurs when the long-sand magnetic-levitation express-line magnetic-levitation vehicle passes through the turnout, and the vehicle can not pass through the turnout beam without adding a damper; therefore, the two problems are researched in 2018 by the Feibao bridge, the problems are solved, and the test is effective on vehicles manufactured by the Beijing S1 line Tang-Dynasty. In 2020, tanzhou vehicle factories (vehicles matched with the long sand magnetic suspension system) propose that no metal can be arranged in turnout beam grooves, and sensors are sensitive to metal signals and influence detection precision, so that the speed measurement structure of the turnout beam needs to be redesigned, and the resonance problem caused by long sand still needs to be solved. The specific problems are as follows:
(1) When the Beijing S1 magnetic levitation vehicle passes through a turnout, the distance and the number of F rail mounting base plates are collected and measured to realize the speed measurement purpose; because the F rail mounting base plate is made of a steel plate with the height of 50mm, the height size is relatively small, when the vehicle sensor 8 passes through a turnout beam, signal acquisition is difficult, the accuracy of sensor speed measurement is influenced, and an emergency braking phenomenon occurs, but because a box-shaped beam structure (as shown in figure 10, the box-shaped beam structure comprises a bottom plate 101, a web plate 102, a partition plate 103, an upper cover plate 104 and an F rail mounting base plate 105, a man-passing hole 1031 is formed in the center of the partition plate 103, and a stiffening plate 106 is fixedly arranged between the web plate 102 and the upper cover plate 104 and the F rail mounting base plate 105), the turnout coupling resonance condition does not occur.
(2) The turnout beam used on the long-sand-line magnetic-levitation express line is of a double-web structure (as shown in figure 11, the turnout beam comprises a lower flange connecting plate 201, a lower flange plate 202, a lower rib plate 203, a partition plate 204, a pair of box beam web plates 205, an upper rib plate 206, an upper flange plate 207 and an upper flange connecting plate 208, a man-passing hole 2041 is formed in the center of the partition plate 204), the partition plate 204 is used for connecting the pair of box beam web plates 205, the widths of the upper flange connecting plate 208 and the lower flange connecting plate 201 are both 200mm, the upper flange connecting plate 207 and the lower flange plate 202 are respectively connected to form a frame structure, an upper cover plate and a lower cover plate are omitted, the structure can meet the requirement that the height of a vehicle sensor 8 is larger than 300mm, however, the self-vibration frequency of the double-box beam web plates 205 is coincident with the frequency of a magnetic-levitation vehicle vibration exciter, the speed measurement is not good in addition, when a vehicle passes through a turnout, the beam body shakes severely, and the turnout resonance of the turnout is serious.
Meanwhile, a switch beam structure adapted to speed measurement of a magnetic suspension running vehicle is disclosed in chinese patent CN201820661660.8, which is a special research aiming at the above two problems (1) and (2), as shown in fig. 12, the switch beam structure includes a bottom plate 301, a short web 302, a high web 303, side cover plates 304, a middle cover plate 305, a partition plate 306 and a sleeper 307; a through hole 3061 is formed in the center of the partition 306; by adopting a box-type beam structure with four webs, namely, an inner web and an outer web, the height difference is formed between the speed measuring plate 3071 of the sleeper 307 and the side cover plate 304, so that the vehicle sensor 8 installed at the bottom of the vehicle frame can sequentially detect different signals on the speed measuring plate 3071 and the side cover plate 304, and the speed measuring problem of Beijing S1 line vehicles is solved by the research at present. However, since there can not be other metal structures in the detection range of the vehicle sensor 8, the accuracy of the detection signal is not high, and the driving safety problem is easy to occur, so that the box beam structure adopting four high and short webs can not be applied to the speed measuring detector for vehicles in a factory.
In summary, it is necessary to redesign the switch beam structure.
