    The invention relates to a method for controlling the lifting-straightening device of a rail-mounted point tamping machine with a tamping unit, with a roller tongs and with at least one lifting hook, wherein the lifting-straightening device is guided longitudinally displaceable in the machine direction. In addition, a device for compacting the ballast bed of a track, in particular in the area of a switch, with a point tamping machine proposed, which is equipped with a tamping unit, comprising at least one roller tongs and at least one lifting hook lifting straightening device for straightening the track.
    Point tamping machines are machines for correcting the track position of points. To determine the track position measuring systems are used, which measure the track height actual position, the track direction actual position and the superelevation actual position of the track during work and align with predetermined setpoints. With the aid of a track lifting / leveling unit, the track grid is lifted and aligned laterally until the difference between the specified position and the actual position is zero. In this position, the switch is determined by compacting the ballast under the sleepers using a Weichenstopfaggregates. The lifting and straightening of the track grate takes place via hydraulic lifting and straightening cylinders with proportional or servo control. Points have a special feature as a continuous track and a branching track. Trains are routed via so-called tongues in the branch or held on the continuous main strand. At the intersection of the continuous track and the branching strand lies the so-called heart. In the area of the centerpiece, the railway wheel must be guided from the rail of the continuous strand to the rail of the branching strand. Thus, the un-guided wheel in the interruption area safely rolls into the branch or in the continuous main strand guide rails are provided. To ensure that the working tools of the points tamping machine can support the points sleepers at all points, the tamping units are displaced laterally and because of the oblique long sleepers, the tamping units are rotatable. The tamping punches can additionally be made at least partially pivotable.
    In the case of pure line tamping machines, the rail is grasped at the head with roll tongs and lifted into the geometric setpoint position. In points, an application of the roller tongs is often not possible because of the intersecting rails and in the heart. In order for these places to be machinable (adjustable), additional extendable and height-adjustable adjustable lifting hooks are provided.
    In addition to pure point tamping machines and line tamping machines, there are also universal machines that can be used both for the track area and for the points area. In the universal machines often two work cabins are running. The Weichenstopfkabine is opposite to the working direction with respect to their viewing direction. From the Weichenstopfkabine from the machine operator controls the position of Stopfaggregates, the pimples, he selects depending on the circumstances and Gutdünken the roller tongs or the lifting hook or the position of the lifting hook and the point thereof at the rail head or rail. The lifting device can also be moved in the longitudinal direction of the track. This is necessary when the lifting hook engages the rail foot - this is only possible in the area of the intermediate compartment - or if, for example, by an insulating joint, e.g. the roller tongs or the lifting hook can not close on the rail head. The Weichenstopfkabine is chosen mainly because of the better view of the lifting straightening device of the points tamping machine. The line tamping machine lies from the viewing direction in the working direction. When stoppers are stuffed only with the roller tongs because no obstacles as switches occur. When stoppers, which is usually carried out at higher speeds, especially the view of the tamping units is important so that they dive exactly in the intermediate compartment and not damage the thresholds with the stuffing tools (so-called tamping). There is a poor view of the lifting equipment from the stowage cabin because the tamping units restrict the visibility. The disadvantage of the design of two work cabins is the considerable extra work involved in the design, two cabins, two control devices, additional weight and increased space requirements. So far, in the execution of a universal tamping machine with only one working cabin (usually those for the distance plug) the view of the lifting device via video cameras accomplished. However, video cameras can not sufficiently replace a spatial view. The manual adjustment of the lifting device, the choice roller tongs or lifting hooks, the positioning of the lifting hook and the force application point, as well as the displacement of the lifting device in the longitudinal direction of the track requires time. Distance measuring devices are also known via odometer or other methods. Since the track set geometry is defined with respect to the arc length of the track, the current position of the machine with respect to the track's mileage must be recorded.
    The invention is therefore an object of the invention to provide a method for automatically controlling the roller tongs and the lifting hook for lifting points by point tamping machines, with which the working speed increases and the error rate can be minimized. In addition, the Auslangen be found with only one work cabin, so that the points tamping machine can build if necessary shorter.
    The invention solves the problem set by the fact that the position of switch components, such as turnout drive boxes, rails and heart, during the right of way the Weichenstopfmaschine using a lifting straightening device upstream in the direction of turnout component measurement system in track transverse direction is measured location-dependent and cached that the location of Thresholds and the intermediate compartments are detected and buffered in the working direction, that the recorded values for the working position of the roll tongs and the lifting hook are queried that on the basis of these values a check is made as to whether the roll tongs are replaceable to this working position and, if the rolling tongs is not applicable, a check on the basis of these values is done to the effect whether the lifting hook on the rail head can attack and if this in turn is not possible that, if necessary, a displacement of the lifting hook in the machine longitudinal direction so erf olg that the lifting hook on the rail foot comes to an intermediate compartment and that the lifting is carried out after gripping the rail with the lifting straightening device.
    According to the invention, the position of the switch components with the lift-straightener in the working direction upstream switch component measuring system is detected and stored path-dependent. Thus, an arbitrary number of practically one-dimensional snapshots of the track cross-section are made in plan view and stored in a database. The stored data can be used to create a digital image of the track, in particular of the turnout components. Based on this, the lifting straightening device is optionally automatically displaced accordingly in the track longitudinal direction along a guide on the machine frame in order to approach a suitable point of application for the lifting straightening tool. In addition, the suitable lifting straightening tool is selected as a function of the measured values of the soft component measuring system, ie between the roll tong and the lifting hook and the extended position of the lifting hook and the point of action of the lifting hook on the rail foot or rail head are automatically selected by a control system. As a result of these measures, one of the two work cabins can be omitted. The automatic control of roller tongs and lifting hooks compensates for the deteriorated view of roller tongs and lifting hooks from the staging cabin and increases the working speed. In addition, a video system can be used to monitor roller tongs and lifting hooks.
    According to the invention, the position of the track components, in particular the switch components (position of the rails, the frog, the siding, the drive boxes for the switch blades, etc.) with respect to the He-be straightening device in the direction of travel path-leading detected. The detection of these components made of steel can e.g. by means of a series of inductive or capacitive proximity sensors, ultrasonic sensors or a laser scanner (for example, scanning every 5 cm equidistantly). The position of the switch components is stored as a function of the distance and transposed by a computer to the position of the roller pliers or of the lifting hook. The path progress of the machine is measured via a displacement measuring device, such as an odometer. The previous measurements are evaluated for the respective position of the lifting and straightening unit. If no sufficient space for manipulation with the rolling pliers found then automatically switched to the lifting hook. Depending on the preceding measurement and the cached data for the current location of the lifting and straightening unit, the extended position of the lifting hook and the rail head is selected as the first point. By measuring the extension position and the closing path of the lifting hook can be concluded whether the head was securely gripped by the hook o-not. If the closing path does not suffice, the hook is automatically opened again. If the lifting hook is not located above the intermediate compartment, then the lifting / straightening unit is displaced in the longitudinal direction of the track until the lifting hook is above the intermediate compartment. At this new position, the attempt to close the rail head again recently, this is not successful (because, for example, an insulating shock is present), then the rail foot is selected as a force application point. If the roller tongs do not grip the rail head successfully, this can be determined by measuring the distance of the hydraulic lock cylinder, then the lifting / straightening unit is moved to a position in the longitudinal direction of the track at which it can be closed. If no such position arise, then the lifting hook is automatically controlled with a point on the rail foot. The measuring device detects on the side of the lifting devices (always on the outside of the rail), the position of the switch components in the transverse direction, as a reference is that rail track on which the points tamping machine and the lifting-straightening device runs. From the position of the switch components detected with the switch component measuring system, a gripping position for the lifting and straightening system is determined, and this gripping position before closing the roller pliers or before gripping the rail with the lifting hook, in particular by transverse displacement, longitudinal movement.
    Displacement and depth adjustment of the lifting straightening system, automatically started.
    The switch component measuring system preferably detects the position of the switch components with a sensor strip comprising a plurality of individual sensors, which sensor strip is arranged upstream of the lift-straightening device in the working direction and with a series of inductive sensors and / or capacitive sensors and / or laser distance sensors and / or Ultrafast distance sensors is equipped. Likewise, the switch component measuring system can detect the position of the switch components with at least one laser scanner.
    An inventive device for compacting the ballast bed of a track, in particular in the area of a switch, with a Weichenstopfmaschine which is equipped with a tamping unit, comprising at least one roller tongs and at least one lifting hook lifting straightening device for straightening the track position and longitudinally displaceable in the machine longitudinal direction Machine frame is guided, characterized in that one of the lifting-straightening device is provided in the working direction upstream switch component measuring system for location-dependent measurement of the position of switch components. In order to ensure that individual positions have been safely approached or the rail has been securely gripped, a lifting hook depth setting cylinder with displacement sensor can be assigned to the lifting hook of the lifting and straightening device, the roll clamp of the lifting and straightening device can be assigned a roll clamp cylinder with closing travel sensor and the lifting Straightening device to be assigned a transverse displacement cylinder with displacement sensor.
    A particularly simple and robust switch component measuring system results if it comprises one, preferably a plurality of individual sensors comprising, sensor bar, which is provided transversely to the machine longitudinal direction aligned on the point tamping machine. For this purpose, the sensor bar a variety of longitudinal strip in the row, ie in a row, arranged Einzelelsenso ren comprise. According to an advantageous embodiment of the invention, it is recommended that the longitudinal direction in the longitudinal direction arranged one behind the other sensors are arranged in two or more juxtaposed rows, the individual sensors adjacent sensor rows are preferably offset to a gap. The switch component measuring system may comprise inductive sensors, capacitive sensors, laser distance sensors and / or ultrasonic distance sensors or optionally at least one laser scanner.
