Abstract
In a sleeper having an actuator for switch tongues (3 a and 3 b), designed as a hollow box sleeper (1) open at the top, for installation in a railway line, in particular in the vicinity of switches, the linkages for the movable switch tongues (3 a and 3 b) and other functional elements such as drive and locking means, monitoring devices, or the like being housed in the hollow box sleeper (1), the hollow box sleeper (1) is provided with a floor trough (8; 8 a; 8 b) for housing the functional elements or parts thereof.
Description
- The invention relates to a sleeper having an actuator for switch tongues, designed as a hollow box sleeper open at the top, for installation in a railway line, in particular in the vicinity of a switch, the linkages for the movable switch tongues and other functional elements such as drive and locking means, monitoring devices, or the like being housed in the hollow box sleeper.
- Such a transverse or hollow box sleeper is known from DE 4,315,200. To allow a cross-sectional width and cross-sectional height that is matched to, for example, a standard concrete or wooden sleeper despite housing of the necessary equipment, the pawls, cam rods, and cam-rod guides are positioned at the upper open side of the sleeper while the lower part of the sleeper holds the tongue-actuating rod and the monitoring rod. For support of the tracks, this hollow box sleeper made of steel has laterally projecting support flanges on its top side. The drive for the locking elements or their linkages is located laterally adjacent the hollow box sleeper, projecting longitudinally from it. Such drives that are flanged or provided on the side or end of a sleeper are also known from DE 42 229 014 and CH 621 168.
- Since they conform in shape to a concrete or wooden sleeper, the known sleepers, i.e. hollow box sleepers, designed as locking sleepers ensure uniform tamping capability of both hollow box sleepers and the adjacent concrete or wooden sleepers. However, despite the compact housing of functional elements and parts known from DE 4 315 200, the installation space is very limited if a drive or parts thereof, a hydraulic lock, for example, are to be additionally integrated therein. As a result of this spatial limitation, the drive or the drive parts or linkage parts of the lock project beyond the upper side of the hollow box sleeper. Such projection is particularly critical due to the minimum clearance, i.e. the ground clearance from the track sleepers, prescribed for railway vehicles. Thus, if the projecting parts come up to the minimum clearance, undesired collisions with downwardly hanging vehicle parts are frequently unavoidable.
- The object of the invention, therefore, is to provide a sleeper of this type that allows integration of a drive means, or at least parts thereof, without the stated disadvantages.
- This object is achieved according to the invention by providing the hollow box sleeper with a floor trough for housing the functional elements or parts thereof. Several advantages may thus be realized at the same time. On the one hand, it is recognized that the floor trough has little or no adverse effect on automatic or manual tamping of the hollow box sleeper. On the other hand, the recessing of the floor trough produces a lower installation space such that preferably the drive or parts thereof may be housed without impairment by any other installed parts situated thereabove in the hollow box sleeper. The floor trough is provided in such a deeply recessed location that in any case, no component projects into the minimum clearance of the railway car. In addition, the floor trough increases the weight of the hollow box sleeper that stabilizes its position.
- The floor trough, which for hollow box sleepers manufactured from steel may be provided either by casting and cold/hot working, may advantageously have a rectangular or trapezoidal cross section. As the result of its angled and upwardly flaring end walls, a trapezoidal floor trough facilitates tamping of the hollow box sleeper.
- According to proposals of the invention, the floor trough may be provided centrally or off-center on the hollow box sleeper. In either case, the hollow box sleeper thus acquires additional positional stability with respect to its longitudinal and/or transverse displaceability.
- It lies within the scope of the invention to make use of the considerable advantages of a floor trough, such that for a hollow box sleeper the drive is provided or installed on the end so that the usual length of a switch sleeper is exceeded. For this purpose, the floor trough is displaced off-center to one side only until it is beneath the drive, and even for such a long hollow box sleeper then provides improved positional stability, i.e. support from beneath and from the sides in the ballast.
- Further features and particulars of the invention result from the claims and the following description of shown embodiments of the subject matter of the invention shown in the drawings. Therein:
-
FIG. 1 is a perspective view of a hollow box sleeper together with running rails and the associated movable switch tongues in reduced scale; -
FIG. 2 is a top view of the hollow box sleeper according toFIG. 1 in larger scale; -
FIG. 3 shows the hollow box sleeper ofFIG. 2 in a section along line III-III; -
FIG. 4 is a cross section of the hollow box sleeper according toFIG. 2 .; -
FIGS. 5 through 8 are views likeFIGS. 1 through 4 , but with another design of the underside of the hollow box sleeper; and -
FIGS. 9 through 12 are views likeFIGS. 1 through 4 , but with a further design variant of the underside of the hollow box sleeper. - A hollow
box sleeper profile 1 shown inFIGS. 1 through 12 , referred to below as a hollow box sleeper, is known per se. In the construction of railroad track systems, the hollow box sleeper is is used for producing the railway track from sleepers and rails, in the vicinity of switches, and is positioned in the ballast bed. Runningrails movable switch tongues slide chair plates - The interior of the
hollow box sleeper 1 accommodates the functional and movable elements for adjusting theswitch tongues lock linkages respective switch tongues switch tongues - A special feature of all the embodiments of the
hollow box sleeper 1 is that on the lower wall 7 thereof afloor trough drive 6 and/or other functional parts to be recessed down into the depression in thefloor trough hollow box sleeper 1 without the required functional and movable elements projecting unnecessarily beyond the upper edge orside 9 of thehollow box sleeper 1. The recessed installation space in thefloor trough upper side 9, and in every case ensures that sufficient distance is maintained from a prescribed minimum clearance 10 (indicated by a dashed-dotted line in the longitudinal sections of the hollow box sleeper 1) of a railway car traveling on the runningrails - For the
hollow box sleepers 1 according toFIGS. 1 through 4 and 5 through 8, thefloor trough hollow box sleeper 1, relative to the longitudinal extension thereof. Whereas thefloor trough 8 has a rectangular shape, the floor trough inFIGS. 5 through 8 has a trapezoidal shape. The laterally flaring,angled end walls 11 of thetrapezoidal floor trough 8 a form an enlarged installation space. - In the installed operating position, the
floor troughs hollow box sleeper 1 according toFIGS. 9 through 12 , in which thefloor trough 8 b is shifted sufficiently off-center and outward so that it houses thedrive 6 and linkage means in an end extension of thehollow box sleeper 1, and thus project therefrom.
