Definitions
- the invention relates to a rail loading train for the transport of
- Anchoring device for anchoring several rails, wherein a separately activatable fixing device is arranged for each rail.
- the invention also relates to a method for operating the rail loading train.
- a rail loader is usually transported from a manufacturing or welding plant or a storage location to a track construction site using a rail loader.
- a rail is held by a conveyor during loading or unloading.
- Clamping process a temporary connection between the rail and the conveyor.
- the rails are fixed on a loading wagon using an anchoring device.
- a rail loading train is known from DE 20 2005 019 061 U1, which comprises an anchoring device for fixing a plurality of rails.
- the device has its own mechanical for each rail
- Each plug-in device can be operated separately, so that during an unloading process there is the option of releasing only the rail gripped by the conveyor from the anchoring. In this way, the other rails remain secured. This is particularly important at unloading points that have an incline.
- Anchoring device for separate anchoring of individual rails is known. There is a remote controllable for each rail
- Insert device for use. It is operated by a protected area, creating unnecessary sources of danger for the
- a rail loading train disclosed in DE 20 2016 003 526 U1 comprises one
- Remote-controlled anchoring device for securely clamping multiple rails.
- an electromagnet is arranged for each rail as a fixing device.
- Each magnet generates a magnetic force that counteracts uncontrolled sliding of the respective rail even when the clamping elements are released. The corresponding magnet is only deactivated when a rail is gripped by the conveyor.
- the invention has for its object a rail loading train
- Another object is to provide a method for operating such an improved rail loading train.
- a transmitter for introducing a signal into a rail to be moved is arranged on the conveyor device and that each fixing device is coupled to a receiver which is set up to detect the signal introduced into the rail in question.
- each fixing device is coupled to a receiver which is set up to detect the signal introduced into the rail in question.
- the transmitter comprises one
- Sound source for introducing a structure-borne sound signal into the rail to be moved
- the receiver comprises a sound sensor for the
- a rail is suitable for that
- the signal is preferably introduced by means of a piezoelectric actuator.
- a device hitting the rail or a vibration motor can also be used as a sound source.
- the receiver preferably comprises a vibration detector on a piezoceramic basis as a signal detector. Signal transmission by means of structure-borne noise works without problems with magnetic fixing devices, because magnetic fields do not affect the signal.
- the transmitter is advantageously set up to generate a modulated signal. This clearly distinguishes it from other signals that occur accidentally at the track construction site.
- the signal is preferably radiated into the rail at a specific frequency with a specific pattern. Frequency modulation can also be useful.
- the signal can be modulated to a specified performance level or another safety-related specification. This may be important for compliance with any standards and regulations.
- the receiver is coupled to a display device for displaying the rail to be moved. In this way, the result of the signal detection can be recognized by an operator.
- the display device for displaying the rail to be moved.
- a further advantageous embodiment provides that the receiver is coupled to a control device in order to automatically solve the fixing device of the rail to be moved. Intervention by an operator is no longer necessary or restricted in this variant focus on the control of work processes. In compliance with the prescribed safety precautions, unloading of rails is possible by operating the conveyor alone.
- these settings can be programmed in advance, so that operating personnel are further relieved.
- Another variant provides that the conveyor as
- Rail manipulator is designed with a gripper arm. This improvement enables the rail loading train to be used more flexibly when loading and unloading rails.
- the rail manipulator is advantageously designed as a gantry crane and runs on rails which are attached to the side of the loading wagons. One conveyor unit is therefore sufficient for handling
- a signal-transmitting component of the encoder is arranged on the gripper arm.
- the signal-transmitting component is an actuator which, when the conveyor device is activated, is automatically pressed against the rail head of the rail to be moved with a defined force.
- the encoder is operated separately
- a simple version of the receiver includes a location sensor in order to locate the rail with the signal introduced. In doing so, everyone
- Rails in the area of the fixing devices are monitored by means of a central detector of the receiver. As soon as a signal is detected, the location sensor assigns it to the corresponding rail.
- the receiver comprises several
- each fixing device being assigned at least one signal detector.
- the monitoring is done separately for each rail, so that no further location is required. It is also possible to simultaneously initiate different signals in several rails and to detect them with the separate detectors. This is done through evaluation and comparison of the individual measurement results, for example with regard to the amplitude or frequency of the respective signal.
- the method according to the invention for operating the rail loading train provides that a signal is introduced into a rail to be moved by means of the transmitter, that the signal is detected by the receiver and an associated signal is output.
- the message signal is available for manual or automatic control of the fixing devices
- the message signal is output to a display device in order to indicate to the operating personnel the fixing device of the rail to be moved. In this way, remote-controlled operation and monitoring of the
- Control device is output and when the fixing device of the rail to be moved is automatically released by means of the control device. This eliminates the need for active intervention by operating personnel, which reduces the susceptibility to errors and the
- the signal is introduced into the rail to be moved by means of the sensor arranged on a gripper arm of a rail manipulator.
- the signal is initiated in the course of a
- a further improvement of the method provides that different signals are initiated in at least two rails by means of respectively assigned transmitters.
- the signals are so different that any crosstalk between the rails does not affect the detection. This increases the efficiency of the process by simultaneously loosening and unloading two or more rails. It makes sense to modulate the signals differently to ensure a robust signal differentiation.
- Fig. 1 rail loading train in a side view
- Fig. 2 detail of a conveyor with encoder
- the exemplary rail loading train 1 in FIG. 1 comprises a plurality of loading wagons 2 which can be moved on a track 4 on rail trolleys 3. Several long-welded rails 5 are mounted on the loading wagons 2.
- a plurality of swivel supports 6 are advantageously arranged, in which the rails 5 lie in a longitudinally displaceable manner. At one end of the
- Rail loading train 1 there is an anchoring device 7 for anchoring the rails 5 during transport.
- Anchoring device 7 can also be in another place of the
- Rail loading train 1 may be arranged.
- Several optional anchoring devices 7 are also possible.
- a rail manipulator with a gripping arm 9 is arranged as the conveying device 8. This is as
- Gantry crane designed that can be moved in the longitudinal direction on the loading wagons 2.
- the anchoring device 7 has a plurality of fixing devices 10, each of which fixes a rail 5 to the rail loading train 1 and can be activated separately.
- each fixing device 10 is equipped with clamping elements which can be brought into a clamping position and released again by means of a hydraulic drive.
- the respective fixing device 10 can have an electromagnet which magnetically fixes the associated rail on the rail loading train 1. This also allows separate fixing and loosening of each individual rail.
- at least one transmitter 11 is arranged for introducing a signal 12 into a rail 5 to be moved.
- This transmitter 11 is shown in FIG. 2 and comprises a signal-transmitting component 13 which is attached, for example, to the gripping arm 9 of the conveyor device 8. In this way, the signal 12 is introduced into the rail 5 as soon as the gripper arm 9 holds the rail 5 in place.
- the signal 12 is detected by means of a receiver shown in FIG. 3
- each fixing device 10 This is coupled to each fixing device 10 via sensors. Either a central signal detector 15 is coupled to a location sensor, or at least one signal detector 15 is assigned to each fixing device 10. With three fixing devices 10, two signal detectors 15 are sufficient if each sensor 15 is assigned to two fixing devices 10. The local assignment of a signal 12 is then carried out by evaluating both detectors
- a direct local assignment is obtained if each fixing device 10 is assigned its own signal detector 15.
- the signal 12 to be initiated is, for example, a
- an acoustic signal 12 is introduced into the rail 5 to be moved.
- 4 shows a frequency-modulated acoustic signal 12 with a constant pulse strength 16 over a time axis 17.
- the rail 5 serves as a medium in which the acoustic signal 12 is transmitted by structure-borne noise from the transmitter 11 to the receiver 14.
- the acoustic signal 12 is initiated, for example, by means of a piezoelectric actuator as the signal-transmitting component 13 of the transmitter 11.
- the actuator is advantageously located on rail tongs 18 which are arranged at the free end of the gripping arm 9.
- a bias by means of a spring ensures that when the rail clamp 18 is placed on the moving rail 5 the actuator is pressed onto the surface of the rail head. In this way, the acoustic signal 12 is introduced into the rail 5 with almost no loss.
- the propagation of structure-borne noise in the rail 5 is also almost damping-free, so that
- the receiver 14 advantageously comprises 15 as signal detectors
- Accelerometer on a piezoceramic basis are fixed and protected in the respective fixation devices 10 or on other rail support surfaces.
- the measurement results are evaluated. This takes place in an evaluation device, which is set up, for example, in the receiver 14 or in a control device 19.
- the receiver 14 is usefully with a display device 20
- This display device 20 can, for example, on the
- Fixing device 10 or be arranged on the conveyor 8.
- Rail loader 1 (e.g. in the rail manipulator) or in a remote control can be useful.
- this device 20 an operating personnel is shown which fixing device 10 fixes the rail 5 to be moved by means of the conveyor device 8.
- an operator solves the corresponding on the basis of this information
- the operator only has to confirm the release process.
- the display device 20 first shows the operator the rails 5 to be released. Then the operator actuates a corresponding control element for the release of a control signal. There is either only one control element for this process or it control element for fixing devices 10 that cannot be released are blocked. In this way, the display device 20 serves as the operator
- Control device before a release of the fixing device 10 is released. Only those already held by the conveyor 8 can be used
- Control device 19 for driving the fixing devices 10 is coupled. As soon as the receiver 14 detects a signal 12 introduced into a rail 5, the control device 19 becomes a characteristic one
- the control device 19 is set up to automatically release the corresponding fixing device 10 on the basis of this signal.
- the rail 5 in question is already held by means of the conveyor 8 before the signal 12 is initiated. In this way, the rail 5 remains secured during an entire unloading process.
