Description

Technical Field

[0001] The utility model relates to the field of maglev tracks, in particular to a track-bearing component used for observing the settlement of a test section of a maglev track. Background Art

[0002] The track beam is an important component 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. In the field of high-speed maglev, the distance between the train magnet and the magnet on the track beam directly affects the change of the magnetic buoyancy force. In order to ensure the smooth development of lift and resistance when the vehicle floats and lands, 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 traditional maglev track beams.

[0003] In the prior art, for the track beam of the maglev track, a group of large magnet modules are generally assembled inside, which are used to provide the forward driving force and the lift required for suspension for the vehicle above at the same time; this kind of maglev method has the disadvantages that the magnet module is too large and is very difficult to manufacture and install; in addition, 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 section tracks for a large number of engineering tests and verifications; however, the existing maglev track beam cannot be installed with the magnet module of ultra-high-speed maglev technology, and is therefore not suitable for the use of ultra-high-speed maglev test section tracks. In order to overcome the above problems, the applicant proposed a track beam structure for the test section of the ultra-high-speed maglev track, but the structure cannot simulate the sedimentation process of the maglev track, and it is difficult to conduct effective tests and analysis on the situation when the track sedimentation occurs during the ultra-high-speed maglev transportation process. Utility Model Content

[0004] The utility model provides a rail support component for observing the settlement of a maglev track test section, so as to solve the problem that the settlement working condition of the maglev track cannot be simulated, and realize the purpose of effectively testing the working condition when the track settles during ultra-high-speed maglev transportation.

[0005] The utility model is realized by the following technical solutions:

[0006] A rail support assembly for observing the sedimentation of a test section of a maglev track comprises a lifting rail support platform, the lifting rail support platform comprises a base, a gasket located in the base and a rail support block, the rail support block is placed on the gasket, the gasket is assembled in the base along a transverse sliding motion, and the rail support block is assembled in the base along a longitudinal sliding motion.

[0007] In view of the problem that the existing technology cannot simulate the working condition of the maglev track settlement, the utility model proposes a rail support assembly for observing the settlement of the test section of the maglev track, wherein the lifting rail support platform is used to be installed on the top of the track beam of the maglev track. The specific fixed installation method is not specifically limited here, and the common bolt fixing, riveting, lock connection, concrete bonding and other methods are all applicable. The lifting rail support platform specifically includes a base, and the base is equipped with a gasket that can slide laterally and a rail support block that can slide longitudinally, so the rail support block is located on the gasket under normal conditions. When the present application is used, the lifting rail support platform carries the upper rail sleeper and the track, etc. When simulating the normal working condition without settlement, the gasket is always kept under the rail support block; when it is necessary to simulate the working condition of the track settlement, the gasket is pushed out of the base from the side to make the rail support block settle downward. The present application can be used to simulate the partial or overall settlement of the maglev track, and the simulation process does not require the use of electrical or hydraulic equipment, with high stability, and can avoid being disturbed by the strong magnetic field environment of the magnet module, ensuring the stable operation of the system.

[0008] Furthermore, the base is in a U-shaped structure with the opening facing upward, which facilitates the assembly of the gasket and the rail block inside the U-shaped structure, so that the gasket and the rail block can be fully accommodated in the U-shaped structure under normal conditions.

[0009] Furthermore, both inner side walls of the base are provided with transversely extending transverse grooves, and the opposite side walls of the gasket are provided with first sliding blocks matching the transverse grooves. The cooperation between the transverse grooves and the first sliding blocks guides and restricts the sliding of the gasket, thereby preventing the gasket from shaking longitudinally and ensuring that the gasket can be pushed laterally.

[0010] Furthermore, the transverse groove is a through groove with both ends passing through the base, which facilitates applying a thrust to the gasket from one side of the base so that the gasket can be pushed out from the other side of the base.

[0011] Furthermore, both inner side walls of the base are provided with vertical grooves extending longitudinally, and the opposite side walls of the rail block are provided with second sliding blocks matching the vertical grooves. The cooperation between the vertical grooves and the second sliding blocks guides and restricts the sliding of the rail block, thereby preventing the rail block from shaking laterally, and allowing the rail block to fall naturally under the action of gravity after the gasket is pushed out.

[0012] Furthermore, the vertical groove is opened from the top surface of the base, and the vertical groove is located above the horizontal groove, which is convenient for disassembly and replacement of the rail support block.

[0013] Furthermore, it also includes auxiliary rail support members corresponding one to one with the lifting rail support platform, and the auxiliary rail support members include a lifting component and an elastic member for lifting the lifting component; in a natural state, the top height of the lifting component is equal to or higher than the top surface height of the base.

[0014] Auxiliary rail supports are also used to be installed on the top of the track beam, and can play an auxiliary bearing role for the upper sleepers and tracks. Considering that this application needs to simulate track settlement, conventional rigid support members are not suitable for use as auxiliary rail supports. Therefore, this solution designs a special auxiliary rail support. In a natural state, the lifting component is lifted to a height equal to or higher than the top surface of the base by an elastic member; after the upper sleepers, tracks and other equipment are installed, the elastic member is compressed under the action of gravity, so that the auxiliary rail support moves down as a whole to the same height as the top surface of the base; after the pad is pushed out of the base, the auxiliary rail support continues to be pressed down, and will not interfere with the normal progress of the settlement simulation test of this application.

[0015] Each lifting rail support platform is equipped with an auxiliary rail support member, which can be installed on the top of the track beam when in use.

[0016] Furthermore, the auxiliary rail support member also includes a bottom plate and a plurality of sleeves fixed to the edge of the bottom plate, the lifting member is movably inserted in the sleeve, and the elastic member is located inside the sleeve and contacts the bottom end of the lifting member. The sleeve limits and guides the lifting member and provides an installation position for the elastic member.

[0017] Furthermore, it also includes a flexible net surrounding all the sleeves on the bottom plate, the flexible net is fixedly connected to the top of each lifting component; and the flexible net is filled with crushed stone particles.

[0018] This solution uses several sleeves to open the flexible net, which rises and falls synchronously with the top of the sleeve. The flexible net is filled with crushed stone particles to simulate the ballast environment. When simulating the settlement, the gravity of the upper sleepers and the like squeezes downward, and the sinking of the sleepers and tracks can be achieved by squeezing the crushed stone particles outward. In addition, due to the presence of crushed stone particles, after all the gaskets are removed, the upper sleepers and other components can gradually sink to avoid sudden falls.

[0019] Furthermore, the flexible net is a nylon net or a metal net.

[0020] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0021] 1. The utility model is a track-supporting assembly for observing the settlement of a maglev track test section, which solves the problem that the prior art cannot simulate the settlement of a maglev track, and achieves the purpose of effectively testing the situation when the track settles during ultra-high-speed maglev transportation.

[0022] 2. The rail-supporting assembly of the utility model for observing the settlement of the test section of the maglev track can be used to simulate the partial or overall settlement of the maglev track, and the simulation process does not require the use of electrical or hydraulic equipment, has high stability, and can avoid being disturbed by the strong magnetic field environment of the magnet module, thereby ensuring the stable operation of the system.
