Description

The invention relates to a Schienenfußhalterung for a track protection fence for all required Absperrbreiten. It is a further development based on DE 20 2005 008 225 U1 ,

Barriers at construction sites of railroad track units must ensure as constantly passively acting devices the accident protection of employees in the field of construction site, where they usually for a certain time on site form-fitting and screwed to the rail of a track against which the protection is to be effected , are mounted. Another requirement is that the distance to the danger zone of a track still traveling by rail can be set variably, thereby avoiding the effects of rolling train traffic on the workers in the construction site area (suction, pressure, vibrations) and the local conditions for setting up the Track Fence can be better taken into account.

According to the state of the art, the fastening of a track barrier to a rail foot is carried out by means of a rail foot clamp, one of the paired clamps often being brought in via an internal or external thread on the rail foot and fixed in a form-fitting manner. However, there are also known solutions that circumvent such complex constructions. In the following, a few concrete examples of the state of the art will be briefly discussed.

To DE 9417106 U1 a kit for shutting off track systems is known, the rail foot forms a sleeve with a thread, in which a threaded bolt with an other-side rail foot clamp is movable. On the sleeve, a piece of pipe or a bolt is mounted in about 45 °, whereupon a boom of the barrier is placed.

In DE 295 04 415 U1 a barrier for track construction sites is described, wherein the boom, its horizontal extension with a Schienenfußklemme and provided with a Schienenfußklemme and slidable sleeve consist of rectangular hollow sections. The individual elements displaceable on the horizontal foot part of the arm are fixed to one another with pin and rail connections.

With DE 295 15 884 U1 a track safety device is known in which similar to the above-described solution, a rail base clamp can be moved over an external thread to the rail foot or away. The otherworldly rail foot clamp is firmly attached to the rail foot mount, wherein a boom of the barrier is plugged onto the end of the rail foot mount leading away from the rail foot. This is attached to it by means of a Verplintung.

To DE 296 05 440 U1 a shut-off device for tracks is presented whose Schienenfußhalterung of a tube with firmly attached Schienenfußklemme, a threaded bolt which is fixed in this tube and points in the direction of a second hereafter Schienenfußklemme so that these Schienenfußklemme pushed it to the rail and by means of a screw on it is strained. The boom of the shut-off device is inserted into the obliquely upwards and away from the track opening of the tube of the rail foot clamp and variably fixed in its display.

According to the known state of the art, solutions are known which consist of too many individual parts and can often be firmly fixed to a rail foot only by means of screw connections, so that the accuracy of fit in the event of damage or contamination can thereby be quickly lost.

The invention is therefore based on the object to provide an improved, adjustable for all required Absperrbreiten, stable and natural oscillations automatically reducing track safety fence, consisting of a few pluggable elements and only one on a horizontal, short section, which otherwise inclined upwards from the horizontal Rail foot mount, together with a sleeve sliding rail clamp fixing manually operated pivot connection, the rail mount with a mounted on its horizontal first section rail clamp easily under a rail through, with low ballast removal, always passed outside a busy track quickly and safely and placed in position can be. With such a maximum simplification of the construction of a track protection fence should also be achieved that a cost-effective and suitable for mass production of all individual elements is possible.

According to the invention the object is achieved as follows, reference being made to the protection claim 1 with regard to the fundamental inventive idea. The further embodiment of the invention results from the protection claims 2 to 4.

The invention relates to a Schienenfußhalterung for a track safety fence with a horizontal first and a second of the Horizontal upwardly inclined portion, wherein the second portion is formed for mounting a multi-bent tube or profile of a cantilever and the first portion with a movable sleeve, which carries an inner rail foot clamp communicates and the end of the first portion with an outer rail base clamp is completed.

The present in this training Schienenfußhalterung for a track safety fence has the advantage that the latter even faster, but in no case less safe and still, without having to enter the track bed, can be attached to a rail of a railway track. Contributes in particular to the inclined rising from the horizontal upward shaping of Schienenfußhalterung and reduced to a required minimum surface of the end face of an inner Schienenfußklemme. It is thus possible, the Schienenfußhalterung with little exposure of the gravel bed, without much effort, outside the track standing, to put under a rail and insert it on this form-fitting manner. Furthermore, all other parts of the track protection fence are in principle without special tools to assemble and they are largely maintenance-free.

The track protection fence advantageously also shows strong vibration damping properties up to its largest shut-off width when the cantilevers are briefly subjected to vertical loading via the transverse struts and the specific characteristic values of the metallic material used for the load-bearing elements are maintained.

In a refinement of the invention advantageously further development is provided that the second portion connects to the first portion of the Schienenfußhalterung and is inclined to this at an angle from the horizontal in the range of 5 ° to 15 °. As a result, the rail foot holder does not have to be handled horizontally in its entire length and inserted under a rail foot, which reduces the friction on the ballast bed of a track and reduces the physical strain on the track construction personnel.

Furthermore, it proves to be advantageous if the inner rail base clamp consists of a front plate and a leg connected to the front plate, wherein the front plate has an opening which corresponds to the inner diameter of the first portion of the Schienenfußhalterung.

The opening in the face plate of the rail foot clamp causes gravel rock to move partially into the interior of the rail foot mount, thus further reducing the resistance when placing the inner rail foot clamp.

Finally, it is essential for the construction of the track protection fence that a Aufsteckbereich of the boom is adapted to the inclination of the second portion of the Schienenfußhalterung and the positive connection between the Schienenfußhalterung in its second portion with the inclined end of the boom via mutually corresponding holes, in conjunction with a Insert bolt, which is secured with a Federsplint done.

Thus, a tube or a profile of an analog, multi-curved cantilever over the end facing him the second portion of the Schienenfußhalterung pushed as a clearance fit and a desired Absperrbreite the track protection fence are made variable.

The completion of the track protection fence by hanging several crossbars between the vertical sections of the boom must withstand dynamic and static loads. Therefore, it is envisaged to hook the cross members in recordings on the vertical section of a boom and secure it by means of double-acting Federsplinten.

The invention will be explained in more detail with reference to an embodiment. This is on the 1 to 7 directed. Show it:
