    Switch with switch heating with metal heating profile, mounted by clamping brackets, and method for installing a switch heating.
    The invention relates to switch heating for train, tram or metro, for passenger and freight transport, preferably with an overhead line above the rail track for the electrical supply of the train locomotive.
    WO2010 / 142720 discloses a prior art switch heating.
    The inventor has invented that the mounting of a heating profile (for electric or liquid heating) on the rail can be improved by using horizontally oriented clamping brackets and / or by using existing mounting means for an existing spare part.
    For example NL1022069C1 (Movares / Icesolution) discloses the mounting of a heating profile directly into the body (also called: the soul) of the rail; the bolt holes in the heating profile are close-fitting. WO2013 / 037635 (TripleS) discloses a clamping bracket mounted on the rail foot that holds the heating profile pressed against the body of the rail, so that the rail remains intact.
    Preferably, one or more of the following applies to the invention: the profile comprises a thin-walled, closed tubular profile of metal, such as steel or stainless steel (for example Titanium reinforced; the profile contains a large hole that preferably holds the base of the clamping bracket). accommodates wide play and allows this base to support directly against the rail, preferably its body, the clamping bracket has a base for preferably directly supporting against the rail, a wing connects on one or both opposite sides of a rail ; the base includes a bolt hole or hole for an alternative mounting means; a wing extends obliquely away from the base and, at a distance from the base, extends in opposite directions; a wing has two or three corners enclosing one another (which at connect directly to each other) and / or the wing encloses a corner with the base, the clamp is made of spring steel, the clamp is mounted with a fastening means, such as bolt, which was already present for mounting a changing part, such as a sliding chair or tongue support; the clamping bracket is mounted by disassembling an attachment means, such as bolt, which is located on the switch, then placing the clamping bracket and then replacing the original attachment means or a similar or replacement attachment means, for example the original attachment means with modification; the base of the clamping bracket rests on a part of a, preferably detachable, exchange part, such as tongue support, which exchange part protrudes, for example, through the hole in the profile and rests directly against the rail soul; the one or more tubes extend behind the change part, possibly included in a recess made in the change part; the replacement part is disassembled, then the profile is placed, then the replacement part is replaced, then or before the clamping bracket is placed, then the replacement part and clamping bracket are fixed, possibly together with the fastener of the replacement part.
    The advantage of the invention includes one or more of the following: for the profile there is freedom of settlement for the inevitable expansion and shrinking due to temperature fluctuations (when the heating is switched on, the profile can reach 200 degrees Celsius or higher, when the heating is switched off minus 15 degrees Celsius or colder ); the profile is pressed over a large length by the clamping bracket because the clamping bracket extends the length of the profile; the clamping brackets are inexpensive; the assembly is reliable; there is little heat loss via the mounting bolt because the heat flow must go from the profile via the clamping bracket to the mounting bolt and the clamping bracket is thin and has few contact points with the profile; the clamping bracket is small in size, so low use of materials; fastening means already present on the switch for an existing switch component are used.
    Further explanation of the invention with reference to the drawing, without restricting the invention thereto.
    FIG. 1: railroad-resistant changeover heated;
    FIG. 2: 1-wing clamp bracket of the invention;
    FIG. 3 + 4: top and side view of fig. 2;
    FIG. 5: 2-wing clamp bracket of the invention;
    FIG. 6 + 7: top and side view of fig. 5;
    FIG. 8 a rail with the invention;
    FIG. 9 is the section along line A-A in FIG. 8;
    FIG. 10: a piece change from above;
    FIG. 11: a photo of a mounted clamp bracket;
    FIG. 12: a photo of a disassembled tongue support.
    The dimensions given in the drawing are in millimeters.
    FIG. 8 shows the mounting with a 2-wing clamp according to the invention of an aluminum heating profile. The base of the clamping bracket rests directly against the body of the rail, for which purpose a hole (preferably rectangular or equal to the shape of the base) is made in which the clamping base fits with ample clearance so that the aluminum profile can shrink unimpeded and expanding without the hole edge sliding against the fixed clamping base.
    An alternative aluminum profile comprises three tubes one above the other, the lower and upper of which contain a ribbon and the side wall of the middle tube contains openings for placing and securing the clamping brackets. This profile can be used for two types of rail by adapted design from one side and the other.
    FIG. 10 shows a part change with tongue supports at the location of sleepers.
    FIG. 11 shows how the base of the clamping bracket rests on the mounting lip of the tongue support. In the alu profile, a large rectangular hole is made between the two sleeves. The base of the tongue support protrudes through this hole and rests directly against the rail soul, as usual. The sleeves run behind the tongue support, for which purpose the base of the tongue support may have received two recesses to provide space for the sleeves. The alu profile is placed by disassembling the tongue support, then placing the alu profile, then replacing the tongue support, then placing the clamping bracket and finally inserting the bolt through the clamping bracket and the tongue support and the rail soul and screw it tight with the nut . The base of the clamping bracket is therefore at a distance from the aluminum profile and rests against the rail soul via the base of the tongue support.
    FIG. 12 shows a disassembled tongue support viewed against the base supporting the rail soul with a recess arranged above and below into which the sleeves of the aluminum profile 10 fit precisely.
    The features disclosed herein can be taken together individually in any other conceivable combination and permutation to provide an alternative to the invention.
