DE1111227B - Track lifter for aligning tracks in a plane perpendicular to the track axis - Google Patents

Description

The invention relates to a track lifter for aligning tracks in a direction perpendicular to the track axis standing plane. When aligning and defining track sections, it is generally known that the procedure is as follows: that initially one of the two rails in relation to the longitudinal profile of the track in is brought to its correct height. The altitude of the second track is then relative to the The first already corrected rail track was improved by anxo is lifted until the desired cross slope of the track is reached.

Spirit levels or pendulums are usually used to monitor the transverse slope of the track Display devices used whose measured values must be read and the operator of the track lifter serve as a guide for aligning the track. Based on the readings is arbitrarily carried out by the operator control of the activity of the track lifter however, time-consuming and exhausting and is therefore often not carried out with the desired care.

The invention is now based on the object of the operator from the part of his job to deliver, which is aimed at reaching the predetermined transverse slope of the track, and to provide an automatic control of the necessary work processes accordingly.

According to the invention this object is achieved in that the track lifter with a pendulum-like Switching element is provided, which is preferably mobile on the resting on both rail lines The track lifter frame is pivotably mounted in a plane perpendicular to the track axis and when a set transverse slope of the track is reached, the one acting on the second track The lifting device of the track lifter switches off.

It is already known in the case of a mobile grading or scraper device that the previously set Cross slope of the scraper blade regardless of the cross slope of the vehicle frame by means of a Switching member and a device controlled by this for pivoting the scraper blade on the once set value to hold. The switching element consists either of a U-shaped, with a electrically conductive liquid-filled tube, which is in each of the two upstanding U-legs has a contact and the liquid is connected to a power source, and works after Kind of a spirit level, or the switching element is designed like a pendulum and has a pendulum Track jack for aligning tracks

Contact members which cooperate with contact members arranged on both sides of the deflection of the pendulum. In the known device, however, the pendulum-like switching element is used - apart from its use in a device of a different type than the invention - another Purpose, namely to maintain a given bank slope of a scraper, and not to control a lifting process so that when it is completed, the object lifted a has a predetermined bank.

According to a further feature of the invention, the switching element can consist of a contact member provided pendulum exist and the contact member arranged on the pendulum on one or both Deflection sides on the track jack frame according to different deflection widths of the Pendulum be assigned a lockable contact member. It is useful to move on both sides of the Pendulum contact elements to be provided, because the pendulum depends on which of the two rail tracks is to be raised, must be able to swing in different directions.

In order to be able to easily adjust the pendulum-like switching element to different transverse inclinations, are contact element lockable on the track lifter frame

carrier adjustable in an arcuate guide corresponding to the pivoting movement of the pendulum arranged and preferably together with the switching element also in the same joint, pivoting .. stored in cash. In order to give the pendulum an opportunity to swing out, the contact member carrier that is not required is swiveled out must be determined, in which case it does not prevent the movement of the pendulum.

Advantageously, the invention is particularly applicable to track lifters whose lifting device is by means of a pressure medium, e.g. hydraulically, can be actuated. In this case, the lifting of the second one can be done later to be straightened rail track required pressure medium supply from an electrically, z. B. electromagnetic, actuatable valve are locked as soon as the actuating device of this valve is over the contact members of the pendulum-like switching element receives current.

An embodiment of the invention is shown schematically in the drawing.

Here, the frame of the track lifter is denoted by 1. The frame is equipped with wheels 2, with the help of which it can be moved on the two rails 3 'and 3 "of the track. How The rails 3 'and 3 "usually rest on cross sleepers 4, which in turn find their bearings on the bedding 5. In the apex of the roof-shaped frame 1 there is a joint 6 in which a pendulum 7 is pivotable camps; furthermore, two also pivotable, but in any position, are stored in the same joint 6 lockable contact link carriers 8 and 9.

The pendulum 7 carries a contact member 10, each of which has a contact member 11 or 12 on the contact member carriers 8 and 9 is assigned. The two contact member carriers 8 and 9 have arcuate slots 14, which are penetrated by the shafts of the wing screws 13; by tightening the wing screws 13 the contact member carriers 8 and 9 can be set in any pivot position. The degree of Pivoting can be read on the scale 15.

Of the lifting device of the track lifter, for the sake of simplicity, only the lifting cylinder 16 with the The reciprocating piston 17, the reciprocating piston rod 18 and the lifting ram 19 are shown. The reciprocating piston 17 is on the one hand by a return spring 20, on the other hand by a pressure medium flowing in via the line 21 influenced. The inflow of the pressure medium conveyed by a pump via line 22 can through the slide 23 - as shown - are locked. The slide 23 is on the one hand by a return spring 24, which seeks to keep it in the open position, and on the other hand it can be electromagnetic be closed when the electromagnet 25 is energized. The stream will supplied to the electromagnet 25 via the lines 26 and 27 from a battery 28, provided the contact member 10 of the pendulum switch 7 one of the contact members 11 and 12 touches.

The device works as follows:

Assume that the track lifter is on a straight stretch where the predetermined bank slope of the track should be zero, i.e. horizontal. The rail line "was already in the course of the Alignment has been raised to its correct height and fixed at this altitude. With the help of a Only the lifting device acting on the rail line is now the line 3 'on the correct one Height, namely to be raised to the height of strand 3 ". The mechanical device required for this (Lifting device) usually consists of a rail clamp or the like and which is on the bedding supporting lifting ram 19 with lifting cylinder 16; constitutes this common mechanical device does not form the subject of the present invention and is therefore not in all of its for the sake of clarity Details shown.

As long as the track has not yet reached the the correct height of the strand 3 "is raised, it was naturally lower than the latter; the pendulum 7 could therefore swing out to the left (in the drawing) without one of the contacts 11 or 12 to touch, especially since the contact member carrier 8, which is not needed in the present situation, so far swung out was found that his contact member 11 in no way with the contact member 10 of the pendulum 7 can come into contact.

The lifting device of the track lifter is now arbitrary by the operator by means of conventional control elements Kind of put into action and sets this activity by supplying pressure medium to the lifting cylinder 16 until the track is in a horizontal position, i.e. both rails' and 3 "locally cherish in the same amount. Since the pendulum 7 - as shown in the drawing - is perpendicular, step but now the contact members 10 and 12 in contact, so that the winding of the electromagnet 25 current receives and the valve 23 closes immediately. This means that the lifting device will start working immediately finished, and the track lifter holds the track ' at its correct altitude until the latter, e.g. by tamping tools, is in this position is fixed. After the correction of the height of the track 3 'has ended, the lifting ram 18, 19 pulled up and the track lift brought to the next correction point. Those means and control organs, which are necessary to raise the lifting ram and to reset the valve 23 can be any be of the usual type and also form no part of the invention; the control of these organs can be done both arbitrarily and automatically.

In track curves, the degree of superelevation, i.e. H. the local bank slope of the track Adjusting one of the contact member carriers 8 or 9 taken into account, the predetermined transverse inclination can be read on the scale 15. Naturally, only that contact member carrier comes into effect, the able to limit the movement of the pendulum caused when the second rail track is raised; the other contact member carrier remains in the swiveled-out position so as not to interfere with the control process hinder.
