A track, in which a track lifting and straightening device with a lifting and straightening drive is arranged in front of the tamping device, and which can positively engage both rails of the track via its own set of wheels capable of running on the track. A stabilizing device is arranged on the bogie frame behind the tamping device as viewed in the working direction, a vibrator is provided which vibrates the tool frame of this track stabilizing device in an approximately horizontal direction; A type of cylinder girdling drive unit which applies a substantially vertical loading force to the tool frame of the device, connected to the cabogie frame and comprising a device for controlling the tool and at least one straightening reference system. relating to things.

Japanese Patent Publication No. 57-. According to document 127001, a movable track straightening tamper with a bogie frame supported on mutually spaced running mechanisms is already known.

In this case, a tamping device and a track lifting and straightening device are arranged on the bogie frame between the two traveling mechanisms. Each tamping device has a tamping tool supported on a height-adjustable tool support via a drive, which tamping tools are moved in pairs with respect to each other by means of a moving drive and a vibrating device. They are moved and vibrated facing each other. The track lifting and straightening device, which is placed in front of the tamping device and is separately arranged on the bogie frame and is equipped with a lifting drive device and a straightening drive device, has a device for controlling the tool, a height reference system and a straightening reference system. We are collaborating. Behind the tamping device in the working direction, a track stabilizing device is arranged on the bogie frame, which can reliably engage both rails of the track via its own set of wheels capable of running on the track. The tool frame of the device is loaded with horizontal vibrations via a vibrator and with a substantially vertical loading force via a cylinder piston drive connected to the bogie frame. With this known track straightening tamper, which cooperates with a track stabilizing device downstream of the tamping device, the tamping tools are advantageously arranged one after the other and the tools for stabilizing the track position are arranged horizontally. Vibrated and vertically loaded.

This provides an overlap of the working barrels of these tools, which is necessary for the effectiveness of both working processes.

Furthermore, according to GB 2,077,821A, a track straightening tamper is known which has a tool support formed as a kind of rudder-rod-like frame with a tool for lifting and straightening the track. The tool carrier of the tamping device and the tool carrier with the track lifting tool and the straightening tool are mounted separately from each other.This tool carrier in the form of a rudder rod is connected at one end via a cardan joint. , and at the other end are pivotably hinged to the bogie frame via a lifting drive.In order to guide the tool support end located opposite the cardan joint onto the track, both lifting A pair of flanged wheels arranged on a common axis between the tool pairs is provided, which at the same time serves as a straightening tool and is connected to a straightening drive. is particularly effective for a secure and stable gripping of the track and for an advantageous automatic positioning of track lifting tools and straightening tools, especially for track curvatures.

The object of the present invention is to provide a track straightening tamper of the type mentioned at the beginning Lτ, which has a more advantageous structure and in which all tools are well positioned with respect to the extension of the track in the horizontal and vertical directions. be.

The structure of the present invention that solves this problem is such that a tamping device equipped with a drive device as a working unit and a track lifting straightening device are arranged in one common tool support frame, and one end of this tool support frame is The tool support frame can be supported on a track via a single running mechanism designed as a support guide and serves as a free pivot axis, and the other end of the tool support frame is hinged to a supporting bogie frame; In addition, the orbit stabilizing device is disposed between the working unit and the titanpa traveling mechanism disposed next in the working direction of the titanpa.

According to the present track straightening tamper in combination with a track stabilizing device, not only the working area of the tamping device and the working area of the track stabilizing device overlap advantageously, but also the tamping device formed as a working unit and by placing the track lifting straightening device on its own tool support frame,
These devices or the tools placed thereon can be made to follow the position of the track in the lateral and height directions, particularly the reference position, with great precision.

This automatic positioning of the equipment is effective and trouble-free, since typically between four and sixteen, or even sixty-two, tamping ice axes for each tamping device are placed in relation to the rail at or near the same time. This is a big advantage for driving.

In one advantageous embodiment of the invention, the common tool support frame of the working units is provided with a bogie for intermittent working feed in the longitudinal direction of the titan pavers in continuous non-stop forward movement of the track stabilizer and the titan pavers. It is coupled to a hydraulic longitudinal displacement drive which is hinged to the frame. According to this embodiment, in particular, intermittent tamping and continuous track stabilization operations are possible in continuous non-stop forward movement of the titan tamper.

This results in particular in a precise track position and a highly uniform compaction of the trackbed. Moreover, by continuously tying forward in order to avoid energy-waste starting and braking, the operator can only carry out intermittent working movements of the working units, in short the tamping equipment, the track lifting straightening equipment. All you have to do is concentrate your attention.

In a further embodiment of the invention, the common tool support frame of the working unit is designed as a rudder-shaped frame;
This frame has, in its end region located close to the tamping device, a single running mechanism, preferably designed as a pair of flanged wheels, and in the region between the other end and the tamping device a bogie. It has a beam-shaped longitudinal support for longitudinally movable support on the frame, and the tool support frame is freely hinged to the bogie frame via a hydraulic displacement drive. . According to this configuration, the tamping device and the track lifting straightening device can be arranged in the titanpa main frame in a particularly simple and compact structure, and the movement of the tool support frame is good in the longitudinal and lateral directions of the titanpa. Become.

In a further embodiment of the invention, the beam-shaped longitudinal support is arranged in one bogie frame, one-sided or double-sided, for movably supporting the working unit on a guide formed by rollers or the like. It has a T-shaped cross section. This simple and robust construction is particularly advantageous for continuous operation.

In a further embodiment of the invention, a likewise rudder-shaped tool frame of the track lifting and straightening device guided onto the track by flanged straightening rollers is connected to the working unit via a track lifting and straightening drive. It is connected to the tool support frame and is hinged at its beam-like end to the longitudinal support of the common tool support frame.

This construction of the track lifting and straightening device as a rudder-rod-like frame, which is common in titanpas, is particularly advantageous in the titanpa according to the invention. By the way, by this,
The track lift below the longitudinal support of the tool support frame of the working unit makes full use of the space for installing the straightening device, and no additional lateral structural space is required.

In a further embodiment of the invention, the track stabilization device is arranged behind the working unit and at a distance therefrom, as seen in the working direction, - a continuous titan tamper with the bogie frame and the track stabilization device; The travel distance of the hydraulic displacement drive for simply intermittent forwarding of the working unit from one tamping point to the next in a non-stop forward movement is at least twice the sleeper spacing. This design ensures a particularly good overlap between the operating range of the tamping device and the track stabilizing device during operation. Furthermore, this allows the tamping process to take longer than normal, for example due to a severely fractured track bed.
The tamping process is carried out regularly, for example by inserting the tamping tool twice, and then the tool support frame with the working unit is advanced by means of a displacement drive, for example in rapid traverse, to the next tamping point. In a titan puncher configured in this way, the practical task is to efficiently and easily operate the orbital adjustment titanpa, which is combined with a trajectory stabilizing device for non-stop forward movement, and to use it for a long period of time without failure. It can almost completely meet your needs.

In a further embodiment of the invention, the piston movement of the displacing drive, which is designed as a double-acting hydraulic cylinder T-stone device, is controlled via a valve device or the like in a series of bogie frames with tie pads or track stabilization devices. The forward movement can be controlled synchronously and in opposite directions. In order to hydraulically control the relative movement between the main frame of the titan and the tool support frame of the work unit in this way, various, some of which are known and commonly used in practice, components or means may be used. can do.

In a particularly advantageous further embodiment of the invention, the tamped track stabilization device is arranged within two tamped track stabilizers that are spaced apart from one another.

In the hitherto known movable track straightening tie tamper, the tamping device and the lifting straightening device have been mainly arranged within the range of two mutually separated tie tamper running mechanisms for the past 10 to 15 years. Also when used in conjunction with a stabilizing device, this arrangement is particularly advantageous with respect to the efficiency and accuracy of the titan tamper.

In a further embodiment of the invention, the vibrating device of the tamping device and the vibrating machine of the track stabilizing device are configured for an in-phase vibratory movement of the tamping tool and the tool frame of the track stabilizing device. ing.

Such a configuration, in other words, a configuration in which the operating range of the tamping tool and the operating range of the track stabilizer tool are in phase with each other, will cause vibrations in the trackbed working area, especially in continuous non-stop working configurations. A significant enhancement and uniformity of compaction throughout is obtained.

In a further embodiment of the invention, the cylinder stone drive for the vertical load and/or the vibrator of the track stabilization device are controlled via a control device and in particular on the basis of a height reference frame. This elevation reference system is also assigned to the working units, in particular to the track lifting and straightening equipment. In this configuration, when the amount of track subsidence due to the track stabilization process is controlled according to the height deviation of the track with respect to the reference height, which is determined in the tamping range based on the height reference system, the work unit and track The height curve of the track completed by the stabilizing device therefore matches the predetermined target height curve more precisely. By using a common height reference system for the track lifting tool and the track stabilization tool, the determination or presetting of the required track lift on the basis of the control or regulating device belonging to the reference system is particularly simple.

Next, the present invention will be specifically explained with reference to the illustrated embodiments.

The track straightening tamper 1 shown in FIGS. 1 and 2 includes a bogie frame 6 that can run on a track consisting of rails 4 and sleepers 5 via two traveling mechanisms 2 and 3.

Furthermore, a vibration device 23 rotatable around an axis extending in the longitudinal direction of the rail.
The tamping tool 22 is also vibrated in a direction perpendicular to the longitudinal direction of the rail.

Approximately in the longitudinal center of the tamping device 13, an inductive generator 24 is arranged on the tool support frame 16, which cooperates with a rail fastening element, for example a rail fastening screw.

The track lifting and straightening device 14 comprises a tool frame 27 which is guided on the track by flanged straightening rollers 25 and is equipped with a lifting roller 26 which can be pivoted into engagement below the rail head. The beam-shaped front end 28 of this tool frame is connected to the tool support frame 1.
It is hinged to a longitudinal support 18 of 6.

Furthermore, the tool frame 27 is hinged to the tool support frame 16 via a track lifting drive 29 and a straightening drive 30 of the track straightening device 14, respectively.

A tamping device 13 is arranged on the tool support frame 16 for each rail 4, which can be raised and lowered via a height adjustment drive 31. In order not to interfere with the height adjustment drive 31, the bogie frames 6 with upwardly convexly bent beams 32 each have a notch 33 extending in the longitudinal direction, as indicated by the dashed line. Between the tamping device 13 and the track lifting and straightening device 14 there is provided a detection mechanism 34 guided without play on the track, through which each rail is configured as a rotary potentiometer. A measuring element 35 is connected, which cooperates with the tension wire 11 of the reference system 10 in order to detect the height deviation between the actual value and the reference value of the trajectory.

The orbit adjustment tamper 1 is equipped with various auxiliary devices.
This results in a continuous non-stop forward movement of the tie tamper with the bogie frame 6 as well as the tamping device 13.
This allows automatic control of various movement functions during intermittent forward movement of the tool support frame 16 from one tamping point to the next. This auxiliary device comprises a control device 9 and a valve device 42, by means of which the hydraulic longitudinal displacement drive 21 can be selectively loaded in both fast motion directions (forward and rearward).

Valve device 42 is connected to three different auxiliary devices for control purposes. One of these is a distance measuring device 43 integrated into the detector 12, which provides one control pulse to the valve arrangement per distance unit of advance distance advanced by the track alignment tamper. This valve device 42 controls the flow of pressure medium into the right-hand cylinder chamber of the longitudinal displacement drive 21 synchronously with and in the opposite direction of the advance distance of the track alignment damper, so that the tool support frame 16 is compacted. Together with the device 13, it is held in a central position relative to the sleeper to be tamped until the end of the tamping process. At the moment of lifting of the tamping device 13, the valve device 42 is switched;

6 is fixed to the beam 32 of the bogie frame 6. In this case, the control of the piston movement of the longitudinal displacement drive 21 is carried out proportionally to the displacement movement of a rod connected to the tool support frame 16 and the rope potentiometer 44 or by an analog signal of the rope potentiometer. This is done by output voltage as .

For controlling the valve arrangement 42, an inductive generator 24 is additionally provided which cooperates with the rail coupling means. This inductive generator 24 remains neutral while in a centered position relative to the intended rail fixing screw. When a deviation from this central position occurs, the inductive generator 24 causes the valve arrangement 42 to change the pressure medium flow to the longitudinal displacement drive 21:
1ifj f wholesale signal is given. As a result, the tamping device 13 is held in a central position relative to the intended sleeper until the end of the tamping process. The track straightening tamper 1, which consists of a track stabilizing device 36 and a working unit 15 consisting of a tamping device 13 and a track lifting straightening device 14 assigned to each rail, therefore selectively The tamping device and the track lifting straightening device are movable relative to each other and are operated with continuous non-stop advance or with right feed, including intermittent feed adapted to the sleeper spacing.
