Estimating the term…
The invention relates to a device (1) which is used to lift and displace the tongue blade (2) of a rail (6), comprising at least two rollers (12, 14) whereby the axes thereof are arranged in an essentially parallel manner in relation to a running rail (4), in order to displace the tongue blade (2) in a transversal manner in relation to the running rail (4), at least two support carrier pins (22, 24) which respectively support a roller (12, 14), and a base body (8) which supports the carrier pins (22, 24). The rollers (12, 14) have a projection which projects in at least one first direction in relation to the base body (8). The inventive device is characterised in that a covering (10) is arranged between at least two adjacent rollers and is oriented towards the first direction and at least partially covers a passage between the at least two adjacent rollers (12, 14).
A device (1) for lifting and displacing the tongue blade (2) of a switch (6), with at least two rollers (12, 14), the axes of which are disposed substantially parallel to a running rail (4) in order to displace the tongue blade (2) transversely to the running rail (4), at least two support carrier pins (22, 24), each of which supports a roller (12, 14), and a base body (8), which supports the support carrier pins (22, 24), whereby the rollers (12, 14) have a projection in at least one first direction in relation to the base body (8),
The device (1) according to one of the preceding claims, characterised in that the top section (8B) and the bottom section (8A) are preferably capable of being fixed to each other in any displacement position.
The device according to one of the preceding claims, characterised in that the covering (10) is at a distance of no more than 5.0 mm, preferably no more than 3.0 mm, from the outer circumference of the at least two adjacent rollers (12, 14).
The device according to one of the preceding claims, characterised in that the at least one roller (14) has a projection in the first direction in relation to a reference point of the base body(8) which is larger than that of the remaining rollers (12).
The device according to one of the preceding claims, characterised in that a first and a second roller (12, 14) are provided, whereby the first roller (12) has a projection of 2.0 to 3.0 mm and the second roller (14) has a projection of 3.0 to 4.0 mm in the first direction in relation to the base body (8).
The device according to one of the preceding claims, characterised in that the base body (8) is provided with an identification mark which indicates the projection of the rollers (12, 14) in each case.
The device according to one of the preceding claims, characterised in that the support carrier pins (22, 24) each have at least one limit stop element (26, 28), especially a collar, which limits an insertion depth of the support carrier pins (22, 24) into the base body (8).
The device according to one of the preceding claims, characterised in that the rollers (12, 14) are supported on the support carrier pins (22, 24) by friction bearings, which are preferably formed by a synthetic polymer layer provided between an inner circumferential surface of the rollers (12, 14) and an outer circumferential surface of carrier support pins (22, 24), said layer especially preferably having self-lubricating properties.
The device according to one of the preceding claims, characterised in that the base body (8) has a symmetrical axis which extends parallel to the rollers (12, 14).
The device according to one of the preceding claims, characterised in that the at least two support carrier pins (22, 24) are provided so as to be incapable of displacement on the base body (8).
