Description

Track construction machine for renewing tracks. The invention relates to a foundry machine for the renewal of tracks, consisting of a machine frame supported on rail bogies with a device for processing a ballast bed, for lifting Ait sleepers and for laying new sleepers, the work group, with devices for transporting the old and the New sleepers, as well as for lifting, guiding and spreading out old rails as well as with a sliding device that can be rolled on the old sleepers to support a rail carriage that is directly upstream of the working group in the working direction.

Such a track construction machine is already known from EP 0 168 103 A2. This machine consists of a first machine frame, supported on two rail carriages, to which a second machine frame is articulated. This is supported at its rear end in the working direction via a rail undercarriage on the track. A height-adjustable chain undercarriage is provided in the immediate vicinity, which is supported on the newly laid sleepers when the rail undercarriage is raised during work. The rear rail carriage of the first machine frame, which is located in the region of the joint, is placed on a sliding device during use. is in turn movable on the old sleepers.

From DE 29 09 575 B a mobile device for laying rails and / or sleepers of a track is known which has two machine frames which are connected to one another by an articulated arrangement and each rest on a carriage at the other end , and in which the working group for picking up the old sleepers and laying the new sleepers as well as the devices for spreading out the old rails and for inserting the new rails are arranged between the two named undercarriages. In addition, in the area of the joint arrangement of the two machine frames, a middle running gear is provided, which is provided with a sliding device during the working phase, which is directly displaceable laterally on the sleepers of the track.

Another type of known track construction machine for renewing tracks is described in DE 28 18 514 B. There is a mobile device for the continuous replacement or renewal of a rail and sleepers existing track shown, which consists of a vehicle association, the main conversion part is designed as a support frame, which is supported with both ends on rail bogies, on which the work organs for replacing or renewing the rails and / or sleepers are attached between the bogies . The supporting frame of this machine is formed from two frame parts which are connected to one another in an articulated manner and which have a height-adjustable third rail undercarriage in the region below the frame joint. In a variant of this invention, in the area of the frame joint, an additional, height-adjustable, metallic drive that can be moved on the new rails upstream of the sleepers is provided for temporary support of the support frame during the work journey.

The aforementioned known machines of the generic type all have two articulated machines or frame parts to which the working members are attached. The consequence of this arrangement is that the machines require a large overall length, a heavy weight and correspondingly high costs.

The present invention has for its object to provide a track construction machine for the renewal of tracks, which avoids the aforementioned disadvantages of the known machine types and which ensures a qualitatively improved and easier operation with a constructionally simple and economically inexpensive construction.

This object is achieved according to the invention with a track construction machine of the generic type in that the working group for excavating the old and relocating the new sleepers is fastened on a boom extending the machine frame outside a section bounded by the rail chassis connected to the machine frame, and in that A height adjustment device is provided between the boom and the work group. The measures according to the invention enable a track construction machine for renewing tracks, which is simple and compact, in particular with a reduced construction length distinguished. The suspension of the work group on a cantilever projecting beyond the rear rail undercarriage allows a swift and simple method of operation which can be clearly controlled by the operating personnel. The quality of work is ensured by precisely placing the new sleepers on the ballast bed prepared by suitable devices, without having to touch the installed new sleepers again before inserting the new rails. This largely eliminates the risk of unwanted shifts in the new sleepers, with the result of a subsequent qualitatively objectionable track position. The short design of the machine allows easy maneuvering and driving in narrow bends and in places with limited space.

An advantageous development of the invention is that a support frame of the work group connected to the height adjustment devices is connected at its rear end in the working direction to a height-adjustable additional rail running gear. This design variant creates improved driving conditions for transport journeys, because the non-negligible mass of the working group is supported by an additional rail running gear on the track and thus the load on the rear rail running gear of the machine or main frame is relieved. At the same time, this improves the maneuverability of the track-laying machine and the possibility of equipping traction and impact devices in the rear area without impairing the quality of work and without a considerable lengthening of the overall length.

In the embodiment according to claim 5, an even further advantage is created in that a transport vehicle is provided which is supported on rail bogies and has a loading platform for supporting the working group during machine transport, which can be detachably connected to the rear end of the machine frame in the working direction by a coupling device is. This advantageous embodiment results in the exemption from aggravating provisions in accordance with the railway transport regulations for transport and maneuvering journeys, since the tractive and impact forces occurring during transport in the train set are directly in the machine by the additional transport vehicle. or the main frame can be introduced without these tensile and impact forces having to pass through the work group and the jib projecting to the rear. This eliminates the need for complex constructions in this area of the machine to absorb the considerable impact and tensile forces in transportation. The machine can thus be transported from one construction site to another in a simpler manner.

A further advantageous embodiment according to claim 6 provides that the working group in its rear end region in the working direction is equipped with devices for inserting rails onto the sleepers. This design makes it possible to equip the machine for the complete renewal of the track with simple and inexpensive means and, in addition to changing sleepers, also being able to replace rails. This design allows the new rails to be placed on the new sleepers, so that behind the machine there is a completely renewed track on which only the rail screw connections have to be attached. Here it is possible to either reintroduce the old rails, which were spread out to replace the sleepers, and place them on the new sleepers (only sleepers change using the old rails again) or new rails, which were previously preferably on the track the sleeper heads were placed on the new sleepers.

A further variant provides a track construction machine according to claim 7, in which the additional transport vehicle, which primarily serves to place the work group in the transport position, is equipped with devices for inserting rails onto the sleepers. In order to be able to lower the working group into the working position during the working phase, the additional rail vehicle is carried behind the machine by means of a distance coupling device at the distance required for an optimal working method, the rails being inserted from the additional transport vehicle . The spacer coupling device is expediently designed in such a way that it also provides the energy required for inserting the rails from the track-laying machine to the transport vehicle can be brought. In order to be able to drive the transport vehicle under the work group raised for this purpose during the transport position, the devices for inserting the new rails, the work item intended for this purpose and any other work organs are expediently foldable and / or displaceable. This embodiment allows the transport vehicle to be carried along during work in a simple manner without it having to have its own drive and its own energy supply. At the same time, the new rails can be inserted from the transport vehicle, an optimal and material-saving work being made possible by a selectable length of the spacer coupling device.

An advantageous combination of the track-laying machine according to the invention is characterized in accordance with claim 8 by a transport vehicle provided behind the track-laying machine for work use with a vehicle frame supported on rail bogies, a drive unit, a driving or working cabin with a central control device and with in the area of the driving - Provided and working cabin and protruding beyond the end of the vehicle frame - height and side adjustable - devices for guiding and storing rails on sleepers.

This system has the advantage that the transport vehicle can operate completely independently of the track construction machine during the working phase. This can be advantageous for inserting the new rails, since this can take place independently of the speed of advance of the track-laying machine. At the same time, this independence allows the additional transport or rail laying vehicle provided with its own drive and energy supply to perform other work on the track, such as material or person transport or other functions. This therefore gives greater flexibility for the implementation of the entire track renewal construction site and can therefore result in overall savings in costs and personnel.
