DETAILED DESCRIPTION

(6) FIG. 1 shows a system, including an installation device 1 and a drive device 10 connected thereto. The system is set down on a rail 3 and is supported by a cross-connector 11, which is connected to the drive device 10, on the rail running in parallel (not shown), and is guided in the longitudinal direction of the rail 3. The installation device 1 includes two gripping mechanisms 5 opposite each other, each of which leads tension clamps 2 between two gripping arms 7a, 7b into their installation positions. In the installation position, the tension clamps 2 are arranged in such a manner that they are arranged both on the rail foot 3a and on an angled guide plate that is set down on a railway tie. Two screw devices 6a, 6b securely screw the tension clamp 2 in their depicted installation position.

(7) FIG. 2a shows a gripping mechanism 5 of the installation device 1 in a loose state, in which two gripping arms 7a, 7b opposite each other, which are tensioned towards each other by a tension spring 14 or a two-way cylinder (not shown), are moved away from each other by a hydraulic cylinder 9 in order to release the tension clamps 2.

(8) FIG. 2b shows the gripping mechanism from FIG. 2a in its clamping position, in which the rubberized supports 8a, 8b on the active surfaces of the gripping arms 7a, 7b of the gripping mechanism 5 clamp the tension clamps 2 in a manner that is force-fitting and at least partially positive-locking. The hydraulic cylinder 9 is in an unswitched position, such that the gripping arms 7a, 7b of the gripping mechanism 5 are moved towards each other by the tension spring effect or the hydraulic force effect in such a manner that the tension spring 14 is kept securely between the gripping arms 7a, 7b.

(9) FIG. 3 shows a top view of a part of the installation device 1 with two gripping mechanisms 5a, 5b arranged opposite each other. The respective gripping mechanisms 5a, 5b are arranged rotatably around respective pivot bearings 15, 16 and are pre-stressed by respective tension springs 17, 18 or hydraulics in such a manner that, without the actuation of the disengaging cylinder arranged between the gripping mechanisms 5a, 5b opposite each other, a pivoting of the tension clamp 2 arranged between the respective gripping arms of the gripping mechanisms 5a, 5b is effected in a pivoting movement along the arrows 20, 21 (shown). A synchronization of the movement of the respective gripping mechanisms 5a, 5b can be effected by the coupling rod 22 arranged between the two gripping mechanisms 5a, 5b.

(10) FIG. 4a shows part of an installation device 1 with two gripping mechanisms 5a, 5b arranged opposite each other in a gripping position, with which the tension clamp screws 23 are screwed out of the angled guide plates 24 to a specified extent by the device 6 for screwing in and screwing out the tension clamp screws 23, in order to enable the tension clamps 2 to be pushed into their installation position by the gripping mechanisms 5a, 5b.

(11) FIG. 4b shows parts of the installation device 1 according to FIG. 4a in an insertion position, with which, after the loosening of the disengaging cylinder 19, the gripping mechanisms 5a, 5b were swiveled into their installation position by the action of the tension springs 2 on the rail 3. The respective tension clamps 2 are now arranged both above the rail foot 3a and above the angled guide plate 24 in such a manner that the installation of the tension clamps 2 can be easily effected automatically by screwing in the tension clamp screws 23 by the device 6 for screwing in and screwing out the tension clamp screws 23.

(12) FIGS. 5a and 5b show a top view of parts of an installation device 1 with gripping mechanisms 5a, 5b, swiveled into the installation position, for the tension clamps 2.
