[0001] the Invention relates to relaparotomy to train for the transport of long welded rails with movable on the track truck loader and located on the end relaparoscopy trains device for fastening rails, consisting of several provided for fixing each of them a separate rail, plug-in devices, each of which has first and second clamping block with a contact surface for contact with the neck rail with force closure.
[0002] Relaparotomy train of this kind is already known from patent WO 2007/065500 A1. He has a device for fastening rails, consisting of several plug-in devices. Each plug-in device has two clamping jaws movable, cylindrical clamping means at each. To connect with force closure of the clamping means with the neck rail or breaking connections, both clamping jaws arranged to approach each other or removal from each other.
[0003] the Task of the invention is to provide relaparoscopy trains of the aforementioned type, which allows using the devices of simple design smooth and largely automated to carry out needed to transport the recording Proc. of sportium long rails.
[0004] This task is solved according to the invention relaparotomy train above-mentioned type by means of signs given in the characterizing part of paragraph 1 of the claims.
[0005] Relaparotomy train, equipped with such a device of simple construction for fastening rails preferably allows the process of clamping rails and end clamping connection remotely, without having to actually perform the operation manually by the operator. While fixing the long rails can be performed by simple lowering of the rail ends in the insertion device during loading of rails by the operator gantry cranes, and rails are fixed instantly, automatically and irreversibly, to be accurately calculate the torque. Breaking the connection can also be made automatically or by remote control by the driver of the crane. Thus, elimination of unnecessary hazards allows you to minimize the risk to personnel.
[0006] Further advantages of the invention arise from the dependent claims and the description of the drawing.
[0007] Below the invention will be described in detail by means shown in the drawing of the example implementation. It shows SL is blowing:
[0008] figure 1 is a schematic side view made according to the invention relaparoscopy trains, figure 2 is a side view of a fixture for fixing rails and figure 3 is a partial top view of the device.
[0009] Depicted in figure 1 relaparotomy train 1 consists of several roaming via rail running gears 2 on track 3 trucks loaders 4 and serves for the transport of long welded rails 5. They are installed in a known manner in three rows one above the other 6 on the supporting pillars 7. For loading and unloading rail 5 is provided with a bolt 8 and a cab 9 valve 10, which can move freely along the crane rails 11 along the trucks loaders 4 and move long welded rails 5 in the longitudinal direction of the trucks or trains. At the end of the 12 relaparoscopy train 1 (preferably at both ends) is a device 13 for fastening rails 5 during transport, consisting of several provided for each separate fastening rail 5, plug-in devices 14. As particularly seen in figure 2, each device 13 has several remote from each other in the longitudinal direction of the rails 20, and vertical plug-in devices 14.
[0010] figure 3 shows that each fixture 13 has at least two posted by the s next to each other transversely to the longitudinal direction of the rails 20 plug-in fixture 14. Each plug-in device 14 has first and second clamping nuts 15, 16, respectively, equipped with the contact surface 17, 18 for contact with the neck 19 of the rail 5. (For clarity, figure 3 shows only the neck 19 of the rails 5.) The first clamping block 15 are rigidly connected to the device 13, while the second clamping block 16 is arranged to be adjusted when using roaming in the longitudinal direction of the rails 20 of the clamping wedge 21.
[0011] the Second clamping block 16 is arranged to move relatively parallel to the contact surface 18 of the axle 22 by removing from the opposite contact surface 17 perpendicular to her swing plane 23. The second clamping block 16 has, in addition, remote from the contact surface 18 and forming with the contact surface of the wedge angle α perpendicular to the pivoting plane 23 inclined contact surface 24. The clamping wedge 21 is arranged to move between an inclined contact surface 24 and the guide wedge 25 parallel to the contact surface 17; 18 and has the contact surface of the clamping pads 26, which forms a contact surface 17; 18 wedge angle α.
[0012] Located on the second clamping block 16 a longitudinal groove 27 is for setting posted on lighting the NII 13 of the bolt 28. Between the first and second clamping nuts 15, 16 is propagating transversely to the longitudinal direction of the rails 20 or in the rotary plane 23, the presser spring 29.
[0013] the Clamping wedge 21 has a hole 30 with internal thread 31, which are secured to lead screw 32. Using run as the engine that runs on liquid fuel 33, the actuator 34 of the lead screw 32 can be driven to rotate around the rotation axis, resulting in the clamping wedge 21 is moved in the longitudinal direction of the rails 20. In addition, the pilot screw 32 is liberating device 36 to adjust the second clamping jaw 16 manually.
[0014] the Fixing or releasing of the rail 5 is as follows. Shown at the right in figure 3 plug-in fixture 14 shows the fixed rail 5, as depicted on the left plug-in fixture 14 shows released the rail 5. After entering the rail 5 in the plug-in device 14 is activated, the actuator 34 and the movement of rotation of the lead screw 32 causes the clamping wedge 21 in a linear, oriented in the longitudinal direction of the rails 20 movement. In the result, the second clamp block 16 or the contact surface 18 is pressed against the neck of the rail 19, and the latter in turn to the contact surface 17 of the first clamping jaw 15. The second clamping block 16 because of the very is the location of the bow bolt 28 of the longitudinal groove 27 has a certain freedom of movement, which avoids jamming of the terminal and provides the precise positioning of the contact surface 18 to the neck rail 19. With adjustable actuator 34 may be set to the exact torque, and thus the optimal clamping force. Release rail 5 is similar in reverse order by bringing actuator 34 in the movement of rotation in the opposite direction. In case of failure of the actuator 34 can be using the releasing device 36 to continue the rotation of the lead screw manually and release the rail 5.
