Description
The invention describes a device for the assembly and disassembly of a fastening device, more preferably a rail fastening device on a support body, wherein the de¬vice is embodied as screw adapter and the screw adapter is to be placed on the rail fastening device.
Various machines for rail fastening are known wherein the primary concern is the screwing in or out of the bolts or the rail screws or the clamping devices for railway tracks (DE 25 50 819 Al, DE 601 03 475 T2, DE 37 20 381 Al).
Here, the screws used can be turned by means of simple hand-guided rotary tools. No additional tool is generally required since the spring/clamp can be manually moved once the screw has been loosened.
The disadvantage of all screwing devices known to date is that these can no longer be used for new types of springs/clamps with a clip function for establishing turn-ing-in from the preassembly into the operating position.
The invention is therefore based on developing a device for the assembly and disas¬sembly of a rail fastening device which sits on the fastening device with an accurate fit and substantially guarantees automated turning in and out of the fastening device in existing engagement stages.
According to the invention this is achieved in that the screw adapter comprising an engagement pin at its stem possesses a centrally arranged recess to accommodate the head of a fastening device in the contact surface of its main body, wherein the main body on both sides next to this recess comprises two mounting pockets embodied trough-shaped as well as a stop!
The mounting pockets on the main body embodied trough-shaped each comprise a lateral guide.
2

The mounting pockets in the main body embodied trough-shaped each comprise a flattened under-grip.
The device for the assembly and disassembly of rail fastening devices can be em¬ployed with track constructions whose support bodies are embodied as both known track sleepers irrespective of type as well as a concrete structure of the fixed road or as another structure.
Advantages of the invention
The fastening device can be automatically turned from the preassembly posi¬tion in the operating or final assembly position and vice versa The exact starting of the screw adapter on the fastening device in the preas¬sembly position is made possible via positions which are defined in the tool by means of engagement stages and which can be automatically approached It is safeguarded that the final assembly position is achieved without twist¬ing/ distortion of the fastening device
The angular offset between the fastening device located on the inside of the track and the fastening system located on the outside of the track relative to the longitudinal axis of the device is automatically offset through the appro¬priate engagement stages when approaching the next engagement position in alternation track inside / track outside so that no overloads can occur During disassembly of a fastening device the screw adapter can be relocated from the final assembly position to the preassembly position by simply chang¬ing the direction of rotation
By forming an engagement pin at the stem of the screw adapter that can be used for nearly all existing screwing devices it can be connected to all hydrau¬lic screwing devices The screw adapter can be operated by one person without problems

The screw adapter 1 on its stem 2 comprises the engagement pin 3 of square design to accommodate the screwing machine which is not shown (Figure 5).
The contact surface 4 of the main body 5 comprises a centrally arranged recess 6 for accommodating the head of the fastening element 7, which is sunk in the support body embodied as sleeper 8 (Figure 1,2).
Furthermore, the main body 5 on both sides comprises two mounting pockets 9; 10 embodied trough-shaped next to the recess 6 as well as centrally a stop 11 (Figure 3, 4, 6). The trough-shaped mounting pockets 9; 10 each additionally comprise on the

main body 5 the lateral guides 12; 13 and an under-grip 14; 15 of flattened design each for accommodating and fixing the spring loops 14 of the fastening device 16.
Figures 7 to 10 show the interaction of the screw adapter 1 with the fastening device 16 and the fastening device 7.
Here, the screw adapter 1 as tool braces itself on the fastening device 7 centrally in such a manner that the force (torque) introduced into the tool during the assembly or disassembly of the fastening device 15 leads to the turning-in of the fastening device 15 onto the head of the fastening element 7 without the possibility of deformation of said fastening element occurring.
The screw adapter 1 via the special shape of the trough-shaped mounting pockets 9; 10 in conjunction with the two lateral guides 12, 13 and the under-grips 14; 15 de¬signed flattened achieves a fixing on the fastening device 16 by means of geometrical positive connection.
