Rail vehicle controllable permanent magnetic slide-proof device
Technical field
The present invention relates to deceleration, braking, the anti-skid device of guideway vehicles such as railway, city underground.
Background technology
At present, the halting point of guideway vehicle, field at home, using pneumatic, surge and the deceleration anti-skid device of various type of drive such as electronic.No matter all there are defectives such as energy resource consumption is big, environmental pollution serious, the braking frictional noise is ear-piercing, brake component serious wear to some extent in the deceleration anti-skid device of which kind of type of drive.Particularly bigger than normal, the complicated integral structure of the volume of retarder, manufacturing and maintenance cost are higher, are the ubiquitous problems of present domestic guideway vehicle deceleration anti-skid device.
Summary of the invention
The purpose of this invention is to provide a kind of rail vehicle controllable permanent magnetic slide-proof device, big, the defectives such as environmental pollution serious, the braking frictional noise is ear-piercing, brake component serious wear of energy resource consumption when overcoming existing vehicle anti-skid device work, and problems such as volume is bigger than normal, complicated integral structure, manufacturing and maintenance cost height.It comprises track fixing device 1, bent plate 2, end iron 3, magnetic guiding loop 4, permanent magnet 5, pull bar 6, leading screw 7, motor 8, feed screw nut 9, bonnet 10, bed plate 11 and overcoat 12, the lateral surface of the riser 2-1 of bent plate 2 is fixed on the track fixing device 1, overcoat 12 is connected on the upper surface of bent plate 2, end iron 3 is fixed on overcoat 12 front end endoporus places, magnetic guiding loop 4 on end iron 3 and its cylindrical of ring set seals the front end of overcoat 12, bonnet 10 is fixed on the rear end of overcoat 12 and with its sealing, be fixed on that bed plate 11 on the bonnet 10 accompanies permanent magnet 5 with end between the iron 3 and the two contacts with the magnetic pole of permanent magnet 5 respectively, the motor shaft of motor 8 penetrates bonnet 10 and fixes with an end of leading screw 7, leading screw 7 screws mutually with feed screw nut 9, and feed screw nut 9 fixes by pull bar 6 and magnetic guiding loop 4.
During work, the identical corresponding inboard that is separately positioned on two rails of two apparatus of the present invention, as shown in Figure 2.When the wheel 26 approachings permanent magnetic slide-proof device of the present invention of guideway vehicle, make motor 8 work, pulling by leading screw 7, feed screw nut 9 and pull bar 6, magnetic guiding loop 3 is moved in overcoat 12 fast, the magnetic loop that is made of end iron 3, magnetic guiding loop 3, overcoat 12 and bed plate 11 is disconnected, above-mentioned parts are disengaged the magnetic screening action that permanent magnet 5 is constituted, and the magnetic force of permanent magnet 5 all discharges through end iron 4.Basic theories according to electromagnetic field, when vehicle passes through in permanent magnetic field with certain speed, (conductor is very big for the conductor that constitutes with the vehicle train, electrical resistivity is lower) be equivalent to be in the time-varying magnetic field, in conductor, have induced current this moment---the eddy current generation, induced current in the conductor can produce the magnetic field of inducting again, between this magnetic field and the former permanent magnetic field application force is arranged, and the direction of application force eternal opposite with the conductor sense of motion (distracted time law).A source of Here it is apparatus of the present invention lock torque.Simultaneously, because permanent magnet is to the suction (suction of the permanent magnet that magnetic energy product is high is sizable) of motion wheel, form the friction force that coupling brought of magnetic material to the vehicle train, friction force can be to the train work done, and this is the source of another lock torque of apparatus of the present invention.End iron 4 pairs of wheels 26 produce powerful magnetic force and eddy effect, thereby operating wheel 26 is produced great resistance, make that vehicle is out of service and keep the halted state of wheel.When guideway vehicle was prepared to sail out of, motor 8 backwards rotation were all masked magnetic guiding loop 3 returns, the magnetic force of permanent magnet 5 by leading screw 7, connecting rod 6 etc., and vehicle can leave.
The present invention is arranged on track parking station, a place, adopts rare earth permanent-magnetic material, and the utilization mechanical drive principle is implemented at a distance the skating vehicle wheel to be controlled by electrical control.Because the present invention does not exist brake component to contact with any of wheel on the vehicle, thereby does not pollute the environment, and can not produce ear-piercing braking frictional noise, also can not cause the wearing and tearing of brake component, volume of the present invention is little, and integral structure is simple, and manufacturing and maintenance cost are low.Have advantages such as energy savings, easy and simple to handle, safe in utilization, dependable performance, high-efficiency environment friendly, can be widely used in that the deceleration of all kinds of guideway vehicles such as railway classification yard train and field, city underground station is anti-slips operation.

Fig. 1 is a structural representation of the present invention, and Fig. 2 is that the present invention is applied to the scheme drawing on the rail, and Fig. 3 is that the A of Fig. 1 is to scheme drawing.
The specific embodiment
The specific embodiment one: specify present embodiment below in conjunction with Fig. 1.Present embodiment is by track fixing device 1, bent plate 2, end iron 3, magnetic guiding loop 4, permanent magnet 5, pull bar 6, leading screw 7, motor 8, feed screw nut 9, bonnet 10, bed plate 11 and overcoat 12 are formed, the lateral surface of the riser 2-1 of bent plate 2 is fixed on the track fixing device 1, overcoat 12 is fixed on the upper surface of bent plate 2, end iron 3 is fixed on overcoat 12 front end endoporus places, magnetic guiding loop 4 on end iron 3 and its cylindrical of ring set seals the front end of overcoat 12, bonnet 10 is fixed on the rear end of overcoat 12 and with its sealing, being fixed on bed plate 11 on the bonnet 10 accompanies permanent magnet 5 between the iron 3 with end and contacts with its magnetic pole respectively, the motor shaft of motor 8 penetrates bonnet 10 and fixes with an end of leading screw 7, leading screw 7 screws mutually with feed screw nut 9, and feed screw nut 9 fixes by pull bar 6 and magnetic guiding loop 4.
Track fixing device 1 is made up of bolt 1-1, chuck 1-2 and holder 1-3, have webge slot 1-2-1 on the right side of chuck 1-2, have webge slot 1-3-1 on the left side of holder 1-3, bolt 1-1 is fixed as one the lower end of the lower end of chuck 1-2 and holder 1-3, and the lateral surface of the riser 2-1 of the right flank of holder 1-3 and bent plate 2 fits and is fixed as one by screw 14.Chuck 1-2 is fastened on the lower-left end of rail 13 by webge slot 1-2-1, and holder 1-3 has guaranteed that by the bottom righthand side that webge slot 1-3-1 is fastened on rail 13 device of the present invention stably is fixed on the rail 13.
