Description

Technical Field

[0001] This utility model relates to the field of magnetic levitation train technology, specifically a combined pole plate suspension device for magnetic levitation trains. Background Technology

[0002] Maglev trains are a modern high-tech rail transit system that uses electromagnetic force to achieve contactless levitation and guidance between the train and the track, and then uses electromagnetic force generated by a linear motor to pull the train.

[0003] The invention patent with publication number CN205573667U discloses a combined pole plate levitation device for maglev trains, which includes a combined pole plate, a levitation electromagnet, and permanent magnets. The levitation electromagnet is disposed on the combined pole plate, and the permanent magnets are disposed on the combined pole plate and distributed on both sides of the levitation electromagnet. In the combined pole plate levitation device provided by this invention, the permanent magnets distributed on both sides of the levitation electromagnet on the combined pole plate enhance the magnetic field on both sides of the levitation electromagnet, making the field strength and levitation force uniform throughout the magnetic field provided by the levitation device, which is beneficial for levitation stability control. This addresses the problem in the prior art where the levitation device used in maglev trains includes a levitation electromagnet, and the load-bearing capacity of the levitation device is determined by the current in the winding of the levitation electromagnet. However, in the above-mentioned levitation device, the strength of the magnetic field generated after the levitation electromagnet is loaded with current varies at different locations, with a higher strength at the position corresponding to the middle of the levitation electromagnet and a lower strength at the positions corresponding to the sides of the levitation electromagnet. This causes the levitation force provided by the levitation device to be concentrated at the position corresponding to the middle of the levitation electromagnet, which is not conducive to levitation stability control.

[0004] Maglev tracks need to be kept clean during use to ensure the safe and efficient operation of maglev trains. Maglev electromagnets are prone to attracting charged dust from the air, which may weaken their magnetism and affect their levitation performance. At the same time, oil and dust on the surface may cause flashover and short circuits, endangering the safety of train operation and negatively impacting the performance of the track. To solve the above problems, this application proposes a combined pole plate levitation device for maglev trains. Utility Model Content

[0005] (a) Purpose of the utility model

[0006] To address the technical problems existing in the background art, this utility model proposes a combined pole plate suspension device for maglev trains. By spraying water onto the maglev electromagnet through a connected nozzle, the surface of the maglev electromagnet can be washed. At the same time, a drive motor drives a drive turntable, which in turn drives a drive crossbar through a push rod. The drive crossbar then drives the connected nozzle to perform a reciprocating pitching motion through a rotating connecting seat, which can wash the surface of the maglev electromagnet from all directions, thereby improving the washing effect of the maglev electromagnet and solving the problems mentioned in the background art.

The magnetic levitation electromagnets are distributed in an equidistant manner. A distribution pipe is installed on both sides of the inner wall of the mounting frame, and a nozzle connecting seat is provided below the distribution pipe. The nozzle connecting seats are distributed in an equidistant manner, and a connecting nozzle is movably connected to the bottom of each nozzle connecting seat.

A push rod is movably connected to the drive turntable. A drive crossbar is movably inserted into the bottom of the push rod. The surfaces of the connecting nozzles are all slidably connected to a rotating connecting seat through a sliding groove. The drive crossbar is movably connected to the rotating connecting seat.

[0010] Preferably, the distribution pipe has a segmented structure, and the connecting nozzle faces the magnetic levitation electromagnet.

[0011] Preferably, fixing frames are welded to both sides of the mounting frame, and the fixing frames are distributed at equal intervals.

[0012] Preferably, water supply pipes are installed on both sides of the mounting bracket via a fixing bracket.

[0015] Preferably, both ends of the water supply pipe are provided with connecting joints, and two adjacent sets of water supply pipes are connected by connecting joints.

[0016] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0017] This invention allows water to enter a distribution pipe by controlling the on / off state of an electromagnetic control valve. The water is then sprayed onto the magnetic levitation electromagnet via a connected nozzle, thus rinsing the surface of the electromagnet and ensuring its cleanliness.

The drive crossbar then drives a connecting nozzle to perform a reciprocating pitching motion via a rotating connecting seat, which can perform all-round rinsing of the surface of the magnetic levitation electromagnet, thereby improving the rinsing effect on the magnetic levitation electromagnet.
