Definitions
- the invention relates to the fastening of rails on their superstructure, usually sleepers, by means of tension clamps.
- tension clamps are used to provide a non-positive connection between a rail foot and a sleeper, usually using an angle guide plate and other suitable devices.
- At least two tension clamps per rail are regularly used on each sleeper, which are assigned to each rail foot of a rail opposite one another, i.e. four tension clamps per sleeper.
- tension clamps When manufacturing and / or repairing a track system, a large number of tension clamps must be mounted and / or dismantled in order to ensure that a rail and an entire track system are securely held on their substructure. These tension clamps are usually installed by hand, but at least they are brought into their installation position. Furthermore, from WO 2018/050917 an assembly device is known which, when placed on a rail and aligned, automatically carries out the screwing of two tension clamps.
- a rail-mounted assembly device for tension clamps for fastening a rail, in particular a rail foot, on a rail sleeper or another rail superstructure.
- the mounting device has a means for releasable connection to the rail, preferably a track comprising two parallel rails, and a drive for moving the mounting device along the rail or the track as well as a means for independently moving to a mounting position and / or for independent track adjustment of the track .

- the invention provides a rail-mounted assembly device which, after simply being placed on the track, can preferably independently carry out the track adjustment and the subsequent screwing over a longer track section at a speed of preferably about 400 m / h.
- the invention provides an assembly device which is able to safely transfer tension clamps from their pre-assembly position into an assembly position resting on the rail foot of a rail. This is preferably done over a wide range of clamping geometries without the assembly device having to be specially converted or re-equipped for this purpose.
- manual work is thus limited to the necessary minimum and the rail fastening process can be carried out essentially and preferably in a fully automated manner.
- the assembly device comprises a gripping mechanism for synchronously gripping one tensioning clamp on each side of the rail foot and for applying a clamping force to the at least two tensioning clamps in order to be able to hold the tensioning clamps securely and to be able to move them into or out of their assembly position.
- the gripping mechanism preferably has two opposing gripping arms which, in a particularly advantageous embodiment of the invention, are pretensioned so as to be movable towards one another by means of a tension spring or by means of a hydraulic two-way cylinder.
- the opposing active surfaces of the two gripping arms have an elastic support, preferably an elastomer support. On the one hand, this increases the coefficient of friction of the active surface, and on the other hand, the elasticity of the support makes gripping more different Allows tension clamps and also provides an increased tolerance in the machine positioning.
- gripper clips or snap locks can be arranged on the gripping arms, which grip the arms of the tensioning clamps resting on the gripping arms of the gripping mechanism and at least partially enclose them.
- the gripping mechanism preferably also comprises a device which is able to counteract the tensioning force caused by the tensioning spring or a hydraulic two-way cylinder.

- the means for track fixing are running wheels on the side of the rail head, which are adjustable in space, preferably adjustable in their angular position relative to one another, are arranged on the assembly device, in particular the base frame. This ensures, with particularly simple and manageable means, that the rail-mounted assembly device can be adjusted to a large number of rail profiles on the one hand and on the other hand ensures compliance with the required track tolerances for every conceivable rail profile and, in particular, keeps the screw and positioning units adjustable to the respective rail profile.
- the assembly device has two opposing gripping mechanisms, which are preferably arranged in mirror image to one another and can be moved. This brings about the preferably simultaneous fastening of two tension clamps, one on each side of the rail foot.
- the movement of both gripping mechanisms can take place synchronously, but optionally a device in which the respective gripping mechanisms can be controlled and moved independently of one another is also possible.
- the suspension and movement of the gripping mechanism is designed in the form of an eccentric swivel, in which the tension clamps are moved from the pre-assembly position to the assembly position in such a way that the tension clamp is defined in advance Dimension of at least 15 mm, preferably at least 20 mm, particularly preferably at least 30 mm, is brought above the angled guide plate into the area above the rail foot, in order to then be lowered onto the rail foot and the angled guide plate.
