Metallic foreign body cleaning plant for rail traffic
Technical field
The present invention relates to a kind of Transit Equipments more particularly to a kind of metallic foreign body for rail traffic to clear up dress
It sets.
Background technology
Rail traffic vehicles at runtime, are powered by wireless power supply system, and operation principle is:Near rail
For industrial-frequency alternating current by rectifier rectification at direct current, direct current is downconverted into the alternating current of high frequency in high-frequency inverter effect,
The alternating current of high frequency excites high frequency magnetic field near rail, and the electricity that can be travelled for vehicle is transformed by electrical energy changer
Energy.
The accumulation that can inevitably have metallic foreign body in vehicle operation region will result in high frequency magnetic field and generates whirlpool in this way
Stream, causes the unstable of electric system, although there is being cleared up metallic foreign body by electromagnet, but due to vehicle
In motion, some excretas etc. are direct emissions on rail, and these excretas can be covered on metallic foreign body, in this way
When metallic foreign body is adsorbed by electromagnet, the dirty substance such as excreta is also followed by metallic foreign body and is attracted to electromagnet together
On, electromagnet is polluted, the absorption property of electromagnet is influenced.

The strut being connect with the cylinder frame body, the one end open of the cylinder frame body, other end closing, the inner wall of the cylinder frame body
Multiple grooves are provided with, the convex block is caught in the groove, and the strut is connected with the output shaft of the first motor.
In a preferred embodiment of the present invention, the metallic foreign body cleaning plant for rail traffic further comprises the electricity
Magnet ontology is integrally formed with multiple convex blocks to be arranged.
In a preferred embodiment of the present invention, the metallic foreign body cleaning plant for rail traffic further comprises described thin
Film is point off formula film.
In a preferred embodiment of the present invention, the metallic foreign body cleaning plant for rail traffic further comprises the electricity
Magnet ontology is cylinder or rectangle.
In a preferred embodiment of the present invention, the metallic foreign body cleaning plant for rail traffic further comprises described
Two motors are servo motor.
The invention solves the defect existing in the background technology, the configuration of the present invention is simple, easy to use, is inhaled by electromagnet
Attached metallic foreign body, in addition, under the cooperation of first motor, electrostatic generator, the second motor and roller, film can be wrapped in electricity
On magnet, since film protects electromagnet, the pollution to electromagnet is avoided.

Specific implementation mode
Presently in connection with drawings and examples, the present invention is described in further detail, these attached drawings are simplified signal
Figure, the basic structure of the invention will be illustrated schematically only, therefore it only shows the composition relevant to the invention.
As shown in Figure 1-Figure 3, a kind of metallic foreign body cleaning plant for rail traffic, including car body 10 and electromagnet
12, first motor 14 is installed, the output shaft 16 of first motor 14 is connected with holder 18, and electromagnet 12 is mounted on branch on car body 10
On frame 18, electrostatic generator 20 is provided on electromagnet 12, the top of electromagnet 12 is provided with roller 22, is wound on roller 22
Film 24, roller 22 are driven by the second motor 26.
The preferred electromagnet 12 of the present invention includes electromagnet ontology 28, the multiple convex blocks being arranged on 28 circumferential surface of electromagnet ontology
30, the strut 34 that holder 18 includes cylinder frame body 32, connect with cylinder frame body 32, the one end open of cylinder frame body 32, the other end
Closing, the inner wall of cylinder frame body 32 are provided with multiple grooves 36, and convex block 30 is caught in groove 36, in this way, cylinder frame body 32 and electricity
Magnet ontology 28 is connected as one, and strut 34 is connected with the output shaft 16 of first motor 14, when first motor 14 starts, is led to
The rotation of electromagnet ontology 28 can be driven by crossing the rotation of cylinder frame body 32.
The preferred electromagnet ontology 28 of the present invention is integrally formed with multiple convex blocks 30 to be arranged, and the intensity of electromagnet 12 is improved.
Preferred film 24 of the present invention is point off formula film, convenient for film 24 and the film that is wrapped on electromagnet ontology 28
Separation, it is convenient and efficient, improve working efficiency.
The preferred electromagnet ontology 28 of the present invention is cylinder, convenient for adsorbing more metallic foreign bodies, but is not limited to justify
Shape, or rectangle.
The present invention preferably the second motor 26 is servo motor, convenient for driving 22 forward or reverse of roller.
In the use of the present invention, the second motor 26 rotates forward, roller 22 is driven to rotate forward, film 24 moves down, and electrostatic occurs
Device 20 starts, and film 24 is adsorbed on electromagnet 12, and first motor 14 starts, and electromagnet ontology is driven by cylinder frame body 32
28 rotations, film 24 is wrapped on electromagnet 12, the reversion of the second motor 26, generates two opposite strength on film 24, i.e.,
Film 24 on roller 22 can be detached with the film 24 on electromagnet 12,12 adsorbing metal foreign matter of electromagnet, due to film 24
