Abstract

In contact line systems with a box-shaped protective housing (1) in which current rails (2, 2', 2'') are arranged overhead, and with a current collector carriage (6) which can be moved in said rails (2, 2', 2'') with exits through a longitudinal slot (132) in the floor (131, 131') of the protective housing (1) there is the need to be able to insert or to remove the current collector carriage (6) at any desired point on the protective housing (1). This is allowed for in that the current collector carriage (6) can be reduced in width and the longitudinal slot (132) in the floor (131, 131') of the protective housing (1) is matched to the width of the reduced width of the current collector carriage (6). <IMAGE>

Designation: conductor rail system

description

The invention relates to a conductor rail system according to the preamble of claim 1.

Such a conductor rail system is for example described in OE-PS 203 544. With the conductor rail system according to OE-PS 203 544 as well as with Refinements based thereon, the current collector trolley from one end face of the protective housing are introduced into the protective housing. The removal of the pantograph trolley, e.g. for repair purposes, takes place accordingly. In the case of installed conductor rail systems, the current collector trolley can be attached to the protective housing can therefore only be assigned or removed from the ends of the conductor rail, unless a part the protective housing is removed from the conductor rail system.

Based on this prior art, the invention is based on the object of conductor line systems of the type in question to be designed so that the current collector trolley can easily be connected to any Place the conductor rail system in the loading

33012

part of the Schleit'leitungsanlage forming protective housing inserted and then again from it can be taken. .

The object is achieved in conductor rail systems of the type outlined above in that a 'reducibility of the width of the current collector trolley is provided and the width of the longitudinal slot '' in the bottom of the protective housing is designed essentially to the width to which the current collector trolley can be reduced.

To insert the current collector trolley into the protective housing as well as to remove the current collector trolley from the protective housing, the current collector trolley is reduced in width so that the current collector trolley enters the protective housing through the passage in the protective housing designed to a corresponding width; ύ can be introduced or removed from it '. After inserting the "current collector trolley" into the protective housing, the current collector trolley, which is reduced in width, is brought back to its actual width, in which the running wheels forming part of the current collector trolley are supported on the tracks of the protective housing.

The reduction in the width of the pantograph agent is expediently done against spring pressure, so that the pantograph trolley without the external force reducing its width further resumes its original width.

Does the protective housing provide sufficient space and if no additional contact-protected busbars are provided, the current collector trolley Tilt out of the protective housing with only a limited reduction in width and in paste into it accordingly. Especially if in addition with one about them. jump down the busbars provided with protection against accidental contact are provided, the removal and insertion of the Pantograph trolley perpendicular to the busbars and thus then also to the protective housing, for this must then of course the width of the pantograph trolley to the width of the in the bottom of the Protective housing provided longitudinal slot be reducible.

To reduce the width of the current collector trolley, the width of the base body can be reduced

The conductor rail system consists of the protective housing or the conductor rail duct 1 and the current collector trolley 6.

In the box-shaped conductor line duct 1, contact-protected (21) busbars 2, 2 ′, 2 ″ are arranged overhead (11) at a distance from one another. On the bottom side, the conductor rail duct 1 is provided with a longitudinal slot 132 which is delimited by downwardly angled edge parts 131, 131 'of the slotted bottom 13, 13'. The bottom parts 13, 13 'that remain standing from the side parts 12, 12' form the running surface for the current collector trolley 6, that is to say for the running wheels 7, 7 ', 7'', ... of the trolley 6.

The current collector trolley 6 consists essentially of a base frame 61 on which the current collectors 8, 8 ', 8''corresponding ^{to the busbars 2, 2', 2 1 'via their sliding pieces, for example 81, are arranged.} In addition, the Lciufräder 7,7 ', ... are mounted on the base frame 61 in a special manner described in more detail below with reference to the wheelset 7/7'; see in particular Figure 4.

- 44.

The axle 71/71 ', which carries the running wheels 7, 7' and telescopes under the pressure of the spring 72 (double arrow A), is mounted in web plates 611, 611 ', which in turn are mounted displaceably in the base frame 61 in the direction of ^{the double arrows A 1} , A ^1. In the brought about by the spring 72 and upright

^ obtained normal position, i.e. with telescoped

Axis 71/71 ', the running wheels 7, 7' are supported on the track 13, 13 'of the conductor rail duct 1 (especially Figure 2).

On the web plates 611,611 'or on each of the web plates on one longitudinal side of the current collector trolley 6, e.g. the web plates 611.611 '', connecting longitudinal webs 612.612 '(Figures 1 and 4) engage the jaws 91, 91 'of actuating pliers 9 (in particular FIGS. 2 and 3). By closing these pliers (arrows B in FIG. 2) are the web plates 611, 611 'against the pressure of the spring 72 shifted inwards and thus the impellers 7.7 ' against the base frame 61, so that the current collector trolley 6 through the width to the width of the Base body or base frame 61 of the current collector trolley 6 designed slot 132 in the bottom of the conductor rail duct 1 in the conductor rail duct 1

-I-

can be guided or taken from it (Fig. 3).

If the closing pressure on the actuating pliers 3 is released, the action of the spring 72, which forms part of the Laufrdddsatzes 7,7 ', results in the opposite movement of the pliers jaws 91,91' (arrows B ', B ¹ in Fig. 3} and the web plates 611,611' and thus then also the telescoping of the axle 71, 71 '(double arrow A) carrying the running wheels 7, 7 *, with which the running wheels 7, 7' resume their running position, ie on the running surfaces 13, 13 'of the Schleifleitunqskanals 1 support.

This opens up the possibility of using the pantograph trolley 6 to be inserted at any point in the conductor rail duct 1 in the conductor rail duct or to be taken from it. This possibility is particularly evident when it is part of assembly lines forming test tracks as advantageous, on which test devices carried by the examiner are used will.

At 82 there is one of the pantographs 8, 8 ', 8' 'outgoing, for example a test device but also a processing tool or the like acting connection cable designated.
