Detailed description

By rail, the term "bus" is used in this specification to refer to all traffic routes which are guided by rails. Examples of such routes are railways, tramways, light railways and subways.

Fig. 1 schematically shows an arrangement according to the invention, mounted on a rail and viewed parallel to the rail, and Fig. 2 shows the same arrangement in a side and partially sectional view.

The arrangement 1 comprises a collection surface 3 made of a non-magnetic material. Such material may be, for example, plastic, elastomer, plastic or elastomer composite, or non-magnetic metal such as non-magnetic stainless steel. Most preferably, the material is selected so that iron-based dust does not magnetically adhere to it, and more preferably, the material is slippery and smooth.

The arrangement 1 further comprises a frame structure 4 to which said collecting surface 3 is fixed. The frame structure 4 comprises at least approximately a rail-shaped profile of the foot 11 and fastening means 8 for attaching the arrangement1 to the rail 9 or to the sleeper. In the embodiment shown in Fig. 1, the fastening means 8 comprise a fastening hook 13 and a fastening flange 14. The fastening hook 13 is fitted through a hole in the fastening flange 14 and the like on the other side of the rail where the hook hook 13 is mainly fitted around the edge of the rail. The assembly 1 can be secured in place by inserting a nut or the like in the threaded portion 15 which is suitably tightened against the mounting flange 14.

The frame structure 4 further comprises a magnet support structure 10, which fits the magnet 2 to the upper surface of the leg 11 of the rail so that the upper surface of the magnet 2 is projected substantially upwards.

The body structure 4 may further comprise a magnet housing 12 within which the magnet 2 is disposed. The magnet housing 12 makes it possible to use not only the massive magnetic body in the arrangement 1 but also, for example, magnetic material in powder form.

It should be noted, however, that the fastening means 8 and the frame structure 4 can of course also be implemented in other ways.

The housing 12 may be made of, for example, metal or plastic. Preferably, the wrapping surface 3 is disposed on the magnet 2 so as to at least cover the upward facing surfaces 5 of the magnet 2. In the embodiment shown in Figure 1, the collecting surface 3 extends past said surfaces so as to cover the substantially sideways facing surfaces of the magnet 2.

According to one idea, the collecting surface 3 extends to the foot 9 or the like of the rail 9 so that at least a substantially dust-tight contact is formed between the Senja rail.

According to one idea, the collection surface covers all or at least substantially the surfaces of the arrangement 1 which are affected by the magnet 2 to collect the metal dust.

The magnet length L can be freely selected. According to one idea, the magnet is of the order of the distance between sleepers.

The thickness and material of the collecting surface 3 are selected such that the magnetic attraction of the magnet 2 acts to collect the metal dust on the collecting surface 3. In other words, the metal dust is trapped on the collecting surface 3 by the magnetic field created by the magnet.

The collecting surface 3 may be a simple planar surface. According to another idea, the collecting surface 3 is shaped to facilitate the removal of metal dust from the track. In the embodiment shown in Figure 1, the collecting surface 3 comprises a trough 6 at its lower edge.

The collecting surface 3 is rigidly and irreversibly attached to the frame structure 4. The metal dust accumulated on the collecting surface 3 is periodically removed, for example, with a textile cloth or brush in a bucket or the like, using pressure medium blowing such as pressurized water or air. thus improving the removal of metal dust from the track.

Figure 3a schematically shows another arrangement according to the invention in an end-to-end configuration and a collecting surface in its collection position, and Figure 3b shows the same arrangement in a collection position in its emptying position.

In this arrangement 1, the collecting surface 3 is pivotally secured by hinge means 7 to the frame structure 4. When the collecting surface 3 is to be puhdis¬taa the accumulated dust from the metal, it is turned in Figure 3a esittämästäasennosta the direction of arrow D as shown in Figure 3b, to the position. Thus, the metal dust can be "dumped" into a collection container such as a bucket, etc. After emptying, the collection surface 3 is turned back to its collection position.

The hinge means 7 may be implemented with hinges known per se, so that they are not discussed further herein. It should be noted, however, that the hinge means 7 may be implemented, for example, with a hinge pin fitted with an inlet hinge or with a membrane hinge made of plastic material.

The arrangement 1 may further comprise locking means for locking the collecting surface 3 in the operating position shown in Fig. 3a.

The collecting surface 3 comprises edges 16 at their edges parallel to the rail, which in turn contribute to the collection of metal dust. The collecting surface 3, whether fixed or pivotally disposed with respect to the frame structure or detachable therefrom, may also comprise edges at all its edges, or may be completely incomplete.

Fig. 4 schematically shows a third end view of a third arrangement according to the invention. This collection surface to form a concave muo¬don 3, in other words, the collecting surface of the rising edges of the central portions korkeammalle.Lisäksi collecting surface 3 is removably attached to the frame structure 4, such that it can be removed for emptying the frame structure 4 in the direction of arrow R edusta¬malla. It should be noted in this connection that the collecting surface 3 may be fixedly arranged with respect to the frame structure 4.

The collecting surface 3 is held in place with respect to the frame structure 4 by means of fixing projections 17. The fastening projections 17 are suitably adapted to the shapes of the frame structure 4. The fastening projections 17 can be made of, for example, prefabricated material, whereby, by suitable dimensioning, they are pressed against the shapes of the frame structure 4. Of course, the operation of the securing projections 17 may be based solely on shape locking. According to one idea, the mounting projections rotate the magnet housing 12 in a frame-like manner.

According to another idea, the collecting surface 3 is fastened to the frame structure 4 by means of fastening and fastening fasteners, such as blind pins or the like.

Fig. 5 schematically shows a fourth end view of an arrangement according to the invention. Here, arrangement 1 is adapted, for example, to a magnetic solution as disclosed in patent specification NL 1018155.

The frame structure 4 comprises fastening means by which the collecting surface 3 is fixed directly to the magnet 2. the fastening means may comprise, for example, fastening projections or other fastening solutions already described above. According to one idea, the collecting surface 3 is fixed to the magnet mounting bracket size 18. The collecting surface 3 can be fixed to the magnet 2 or its mounting bracket size 18 for rotating! or removable. The collecting surface 3 may have the shape and material shown in the above figures.

The collecting surface 3 extends on the rail 9, on its ridge, thereby allowing the accumulation of metal dust on the collecting surface to be enhanced. Obviously, the collecting surface 3 may be different in the ways already described in connection with the above figures.

In some cases, the features set forth in this application may be used as such, despite other features. On the other hand, the features disclosed in this application may be combined, if necessary, to form different combinations.

In summary, the arrangement according to the invention is characterized in that it comprises a collecting surface made of a non-magnetic material body structure, to which said collecting surface is fixed, which body structure can be fitted with that the magnetic attraction of the magnet acts on the collecting surface to collect the metal dust.

The drawings and the description related thereto are only intended to illustrate the idea of the invention. It will be apparent to one skilled in the art that the invention is not limited to the embodiments described above, in which the invention is described by way of some examples, but many modifications and various embodiments of the invention are possible within the inventive concept defined in the claims below.
