Description
Technical field
The present invention is mainly concerned with the design field of magnetic-levitation train, refers in particular to a kind of electromagnet protecting device that is applicable to often lead attraction type magnetic-levitation train.
Background technology
The electromagnet of magnetic suspension train is the visual plant of train.Referring to Fig. 3, electromagnet 1 is installed on the bogie truck 2 of often leading attraction type magnetic-levitation train and cooperates 2 bottoms of being fixed in car body 3 of bogie truck with track 4 formation.Referring to Fig. 4 and Fig. 5, traditional electromagnet 1 is by comprising that 13(unshakable in one's determination is yoke), pole plate 11 and magnet coil 12.This magnet coil 12 can produce magnetic field after the energising in electromagnet 1, and magnetic field is closed in the loop that iron core 13, air gap and track 4 form, and forms electromagnetic attraction.When attractive force makes electromagnet 1 be adsorbed onto on the track 4 unusually, electromagnetic force will sharply increase, and further make electromagnet 1 adsorb tightly track 4, and this will damage electromagnet 1 and vehicle.When preventing electromagnet 1 absorption track 4 to the damage of electromagnet 1; reduce the deceleration/decel of vehicle this moment; there is the practitioner to propose; can install the protection boots 10 of making of diamagnetic material at the pole surface of electromagnet 1; electromagnet 1 pole surface can be attached on the orbital plane 4, and the gap certain with track 4 maintenances.
Existing protection boots 10 generally have two kinds of mounting meanss, and the first is as shown in Figure 6, directly will protect boots 10 to be fixed on the pole plate 11 of electromagnet 1 with screw 104; The second is as shown in Figure 7 and Figure 8, makes respectively dovetail and the dovetail furrow that cooperatively interacts on 11 on the pole plate of protection boots 10 and electromagnet 1, and protection boots 10 are loaded in the dovetail furrow of pole plate 11, and both sides add screw 104 with clamping plate 103 and fix.In the first kind of way, when electromagnet 1 unusual absorption track 4, protection boots 10 can damage the head of screw 104 with track 4 rapid frictions, and make screw 104 and protect boots 10 fusibles together, and it is very difficult that protection boots 10 are changed.The second way is actually a kind of the improving one's methods that proposes for the former problem, but the deficiency that it exists just is: open the magnetic flow that dovetail furrow will affect electromagnet 1 on 11 on pole plate, reduce exerting oneself of electromagnet 1; The making of dovetail and dovetail furrow, clamping plate 103 installation grooves will make the structure complicated of fender guard in addition, and cost raises, and the different differences that cause thermal expansion coefficient of dovetail and dovetail furrow material will cause protecting boots 10 dismounting difficulties.
Summary of the invention
The technical problem to be solved in the present invention just is: for the technical matters that prior art exists, the invention provides the electromagnet protecting device that is used for often leading attraction type magnetic-levitation train of a kind of simple and compact for structure, with low cost, easy accessibility, good reliability, long service life.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of electromagnet protecting device for often leading attraction type magnetic-levitation train; comprise the protection boots that are installed on the electromagnet; it is characterized in that: described protection boots are L-shaped, and the one side of described L shaped protection boots is arranged on the upper surface of pole plate, and the another side of described L shaped protection boots is arranged on the pole plate side.
As a further improvement on the present invention:
Be connected by screw fastening between described L shaped protection boots and the pole plate side.
The one side that described L shaped protection boots link to each other with the pole plate upper surface equates with the pole-face width of pole plate.
Two ends of one side that described L shaped protection boots link to each other with the pole plate upper surface are equipped with crashproof chamfering.
Described protection boots are made by diamagnetic material.
Compared with prior art, the invention has the advantages that: the electromagnet protecting device for often leading attraction type magnetic-levitation train of the present invention, simple and compact for structure, with low cost, easy accessibility, good reliability, long service life, occur farthest to protect polar electromagnet and vehicle when unusual at electromagnetic force; The present invention can not destroy the electromagnet original structure when implementing, make Electromagnetic Design can be absorbed in the relevant electrical design of electromagnetic effects, needn't consider the impact of structure; And, lowered fender guard manufacturing cost and difficulty, greatly simplified the installation and maintenance of device.

The specific embodiment
Below with reference to Figure of description and specific embodiment the present invention is described in further details.
As depicted in figs. 1 and 2; the present invention is used for often leading the electromagnet protecting device of attraction type magnetic-levitation train; comprise the protection boots 10 that the diamagnetic alloy material that is installed on the electromagnet 1 is made; protection boots 10 are L-shaped; the one side of L shaped protection boots 10 is arranged on the upper surface of pole plate 11, and the another side of L shaped protection boots 10 is arranged on pole plate 11 sides.Be fastenedly connected by screw 104 between L shaped protection boots 10 and pole plate 11 sides.When electromagnet 1 attractive force occurs when unusual, electromagnet 1 pole-face will be adsorbed onto on track 4 pole surfaces.Protect this moment boots 10 to contact first the pole surface of track 4, make the pole-face of electromagnet 1 keep not contacting with the pole surface of track 4.Make because protection boots 10 are diamagnetic materials, electromagnet 1 maintains certain interval with track 4, and the electromagnetic force of this moment can not be tending towards a great value; Because the choosing of protection boots 10 materials, its friction coefficient with track 4 is less, and is just less along the friction force of vehicle operating direction in addition.This has just played the effect of protection electromagnet 1; Reduce simultaneously the deceleration/decel of vehicle, protected vehicle.
In the present embodiment, the one side that links to each other with pole plate 11 upper surfaces of L shaped protection boots 10 equates with the pole-face width of pole plate 11.Two ends of one side that L shaped protection boots 10 link to each other with pole plate 11 upper surfaces are equipped with crashproof chamfering.
In concrete application process, can be according to thinking of the present invention, on 11 on two pole plates of an electromagnet 1, fourth officer protection boots 10 are installed respectively.
Below only be preferred implementation of the present invention, protection scope of the present invention also not only is confined to above-described embodiment, and all technical schemes that belongs under the thinking of the present invention all belong to protection scope of the present invention.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the principle of the invention prerequisite should be considered as protection scope of the present invention.
