Definitions

• the invention relates to an actuating device for a track section to be adjusted, in particular a switch actuating device, with a connecting element emanating from the actuating device, for example for B. a slide rod, the actuating device comprising a guideway defining a travel path, a slide and a slidable along the guideway, lockable in predetermined positions by this rocker,
• actuating devices can be arranged along the track section, directly or indirectly from which slide rods originate, which interact, for example, with clamp closures, via which turnout tongues are locked or unlocked.
• the actuating device specifies the travel path of the slide rod, the end positions of the track section possibly being checked by a monitoring device provided in the actuating device.
• An actuating device of the type mentioned at the outset can be found in DE 31 06 708 C1.
• the present invention is based on the problem of developing an adjusting device of the type described above in such a way that an adjustment should be possible in a structurally simple manner with a compact structure, but at the same time it must be ensured that an uncontrolled adjustment is excluded if one of the end positions ⁇ nen is present.
• the problem is essentially solved according to the invention in that the slide, from which the connecting element originates, interacts with the rocker in such a way that when a force acts on the rocker in one of its locked positions from the slide, the rocker cannot be displaced with the slide and with one alone force acting on the rocker can be moved together with the slide.
• the rocker preferably has at its ends locking elements engaging in recesses in the guideway, between which a driver acting on it runs, via which the rocker can be displaced along the guideway.
• the driver can preferably be driven via a spindle running parallel to the guideway.
• the rocker itself preferably comprises two parallel and spaced-apart arms, between which, on the one hand, the rollers are supported on the guideway and, on the other hand, they engage in the recesses of these rollers as the locking elements, which are in turn mounted on axles penetrating the arms of the rocker on the outside have additional roles on the arms, on which the driver acts to move the rocker.
• the driver itself is preferably fork-shaped with legs running along the outer sides of the arms of the rocker. Above the seesaw, the legs can be connected via an upper cross leg. The side legs can then extend with an extension above each of the locking elements or the further rollers if these are located in one of the cutouts. This provides additional protection against uncontrolled movement of the rocker.
• each leg itself can run parallel to one another and widen in the direction of the carriage, each leg preferably having a constriction between the rollers and the area remote from the carriage, that is to say has a geometry which consists of two merging into one another and at their tips lapping triangles.
• the driver and the rocker form an adjustment carriage which can be moved along the guideway and which is preferably surrounded at least at the end and head sides by the carriage, side sections running parallel to the guideway interacting with end regions of the arms of the seesaw or the outer rollers, so that when the slide acts on the rocker force of the carriage can be taken from the seesaw or on the slide acting on the rocker force acting as locking elements rollers are pressed into or fall into the associated recesses of the guideway, so that a displacement of the Carriage and thus the slide rod which is directly or indirectly emanating from this is excluded.
• This is done on a structurally simple Way a mechanical lock that ensures the functionality of the actuator.
• the connecting element leading to the slide rod itself starts from the upper side of the slide, so that there is a simple fastening with an accompanying compactness.
• the guideway is preferably a flat iron which runs vertically with its flat side, in the upper edge of which the recesses are provided, the spacing of which from one another in the actual sense predetermine the adjustment path.
• the guideway can be exchangeable, so that with one and the same slide and one and the same adjusting carriage actuating devices can be made available which can be designed for different actuating paths. For this it is only necessary that guideways corresponding to the travel path are used.
• the actuating device can comprise a housing, which consists of a base plate and side walls, in the longitudinal direction of which web-like projections extend which engage in the longitudinal grooves of the slide.
• a housing which consists of a base plate and side walls, in the longitudinal direction of which web-like projections extend which engage in the longitudinal grooves of the slide.
• longitudinal slides extend from the slide and engage in correspondingly adapted grooves in the side walls. In this way, secure guidance of the carriage is ensured
• the spindle which passes through a base section of the fork-shaped driver, which together with the rocker, as mentioned, forms the adjusting carriage acting on the slide preferably runs above the base plate.
• the spindle can also be arranged elsewhere.
