The invention relates to a device for in the longitudinal direction of the track progressive lifting of a track section to a predetermined height by means of one on a vehicle, preferably on a track tamping machine, arranged track lifter, in which the attainment of the correct altitude by observation an indicator mark on the track lifter is determined by means of an optical sighting device, which on the one end of the track section is set up so that its line of sight is parallel over the desired track position runs.

In a known device of this type, the operator has observed his position on the sighting device through this the indicator mark on the track lifter and operated via a remote control system from this point from the track lifter. The operator can continue to advance the track lift vehicle or remote control of the track tamping machine and, in the case of the latter, also the actuation of the tamping tools.

It is further known, so-called industrial television systems, in which a television recording device has a suitable for high-frequency image transmission Broadband cable is directly connected to a screen for remote observation Measuring apparatus or the like, in particular to be used for their reading. It is also in the Conveyor technology, e.g. B. in extraction and conveying devices with extensive extraction equipment, or known in tower cranes to use television systems with the help of the excavator or The crane operator can control the work of the extraction device or the picking up or setting down from the control station can observe loads outside his natural field of vision. With tower cranes it is also known if the workplace from the operator's station is insufficient or not at all can be seen to control the crane remotely from the work site.

The invention is based on the object 'in a device of the type specified above Observation through the sighting device from the track jack vehicle or the. Enable track tamping machine and thus to give the operator their place on the vehicle. Such an order offers the advantage that, in addition to observing the track movement, the operator can use the Sighting device also the operation of the track lifter, the ancestor of the device and in particular the Work the tamping tools in place. over- », can watch.

According to the invention, the object is thereby achieved in the longitudinal direction of the track

solves that on the optical sighting device a television recorder is arranged, which is connected to a television screen on the control station of the Track jacking vehicle or the track tamping machine is in connection, so that from the operator's station from the movement of the marker on the track lifter on the screen can be observed.

An exemplary embodiment of the invention is explained below with reference to the drawing.

Fig. 1 of this drawing gives an overall overview of the device in its interaction with the remote optical sighting device,

FIG. 2 illustrates the function of the track lifter in the embodiment variant according to FIGS. 1, and

Fig. 3 is a section along the line IH-III in Fig. 2,

In Fig. 1, 1 is on the wheels 1 'mobile Track tamping machine referred to, which belongs to any of the known genera. The one shown Machine 1 carries a track lifter on its front side which protrudes over the track section to be tamped 2 with an indicator mark in the upper part, onto which the line of sight of a sighting instrument 3 is directed is. The optics of this sighting device 3 is under observation of a television recorder 4, which is with 'eMem' on the screen located on the tamping machine 1 5 or the like via a coaxial cable 6

is. The rails 7 of the track rest as usual on the cross sleepers 8 of the superstructure.

The entire system, including the details of the track lifter 2 not belonging to the invention, is shown schematically on a larger scale in FIG. The sighting device 3 resting on the tripod 3 'consists essentially of the stand 9, on which the optics of the device are pivotably mounted, and of the scale 10, with the aid of which the angular position of the optics is regulated. The recording device 4 is arranged on the sighting device 3.

The track lifter has a gripper 11 in a known manner; the pliers of this gripper 11 is, however additionally equipped with a feeler element 11 "to ensure that the indicator mark 2 'is on the track lifter always has exactly the same distance from the upper edge of the rail. The gripper 11 is known in Way of one of the cylinder 12, the piston 13 with the piston rod 13 'and the return spring 14 existing device is actuated, with a pressure medium via the line 15 to the cylinder 12 can be fed.

The actual lifting of the rail 7 and thus the track 7, 8 takes place by supplying pressure medium to the Cylinder 16, in which the piston 17 slides and is influenced by a return spring 18, which it seeks to press downwards with slight pressure, so that the feeler element 11 "constantly touches the upper edge of the rail touched. At the lower end of the piston rod 17 'of the piston 17, the gripper 11 is provided, whose pincer joint is denoted by 11 '. A feed line 19 supplies the cylinder 16 with pressure medium.

To control the pressure medium supply to the cylinders 12 and 16 of the track lifter is used from the Slider 21 and the housing 20 existing control member, which via the piston rod 21 'from the control lever 22 is actuated, which is pivotable about the joint 23 in three different positions I, II and III. Via a supply line 24, the slide is removed from a storage container 26 by a pressure medium pump 25 supplied with pressure medium. A pressure relief valve 27 leading to the return line 28 ensures the limitation the maximum pressure in the cylinders of the track lifter.

The operation of the device is as follows: The operator of the machine has it to Let it drive up to the next threshold to be stuffed. Before he even got to the actual darning work begins, he sets the track lifter 2 in action by moving the control lever 22 from the rest position I, in which the pump 25 returns the pressure medium via the pressure relief valve 27 to the reservoir 26, adjusted to working position II. The valve 15 'in the line 15 is open so that the cylinder 12 of the gripper 11, the latter being pressed against the rail 7 by the spring 18 in the lifting cylinder 16 is, pressure is received and the gripper 11 closes. The lever 22 is now moved into position III, so that the lifting cylinder 16 of the track lifter also receives pressure and the rail 7 against the pressure of the spring 18 is raised.

The operator looks at the screen of the television system and sees the indicator mark 2 'of the track lifter 2 on the one hand, and the crosshair of the sighting device 3 on the other no longer lifted, but remains in

-5 raised position, because the pressure in cylinder 16 at least in the short term; the threshold above which the tool carrier of the tamping machine is located is currently located, can now be fixed in its height position by tamping. The operator

ίο only needs one of the two rails, as described above, the height of the other rail can then be measured using an on the machine in conventionally existing inclinometer, e.g. B. od a spirit level. Like. Be determined.

In the course of the tamping work as well as after it has been completed, the operator can continuously disconnect from the Convince the correctness of the height of the track by looking at the screen; corrections the altitude can be carried out immediately by further lifting or re-tamping.

After the tamping has taken place, the gripper 11 can quickly be moved into position I by moving the slide 21 be released, the cylinder 12 and the cylinder 16 quickly depressurized via the return line 28 will; the machine can now drive to the next threshold, using the button 11 "on the rail head grinds, which is why friction-reducing agents such as rollers, balls or the like are used at this point, recommend. The gripper 11 be put out of action by the shut-off valve 15 '; the gripper is released in the released state Adjusting the slide 21 raised according to III and can then in the raised position by any mechanical means are fixed.
