A working space, which is open towards the track (3), is provided in a region located between the two rail bogies (4) which are spaced apart from one another. A clamping device (13) which is designed to connect the vehicle frame (8) to the rails (2) in a frictionally locking fashion, is respectively arranged at each frame end (6). At least one of the clamping devices (13) is designed to be adjustable in the longitudinal direction (5) of the vehicle relative to the vehicle frame (8) by means of a drive (17).

Description

Safeguard vehicle

Technical field

The present invention relates to a kind of vehicle of safeguarding, this safeguards that vehicle has the vehicle frame extending along longitudinal direction of car, this vehicle frame each framework end have can the track at railway line on mobile track running mechanism, wherein in the region between these two track running mechanisms that are spaced apart from each other, be provided with towards the open working space of this railway line.

Background technology

From EP1789299 known a kind of this type of vehicle.This vehicle K/UP there is working space under the vehicle frame that forms, this working space is by limiting at the transversely adjustable sidewall of railway line or guaranteeing in two longitudinal direction of car sides, movably lifting and equipment be equipped with and, to carry out various railway line upkeep operations.When changing orbital segment (Passschienen), use extraly in known manner track tensioning device, to remain on the longitudinal tensioning in cut track.

According to the known a kind of device that can travel on railway line of JP2555508, for the seam distance of correcting track.For this purpose, two track holding devices are articulated in the approximate mid-section on machine frame and in these track running mechanisms, and these track holding devices not only can regulate but also can regulate with respect to this machine frame on railway line is longitudinal relative to each other by means of actuator.

Summary of the invention

So the object of the present invention is to provide the vehicle that is very suitable for changing track of type described in a kind of introductory song.

This object is to be realized by the vehicle of described type by the present invention, it is characterized in that, at each framework end, dispose the holding device that is designed to connect with friction lock pattern this vehicle frame and track, and at least one in two holding devices is designed to along longitudinal direction of car, with respect to vehicle frame, to regulate by means of actuator.

By thering is the vehicle of this feature, can carry out more rapidly and more simply in an advantageous manner the replacing of orbital segment, because can fully phase out and use separated track tensioning device, the relatively high algorithm expending by the present invention.After cutting track section, still need to keep, being longitudinally tensioned in track be by stable vehicle frame, to absorb simply, and by means of this holding device directed force this vehicle frame of flowing through.By means of being used for longitudinally regulating the actuator of this holding device, can be with human factor engineering convenient and safe mode essential push/pull pre-tensioning is applied on track.

Another advantage of the present invention is, via this track running mechanism, vertical loading is in longitudinally clamping and fixing railway line at it extraly and side by side in this deadweight of safeguarding vehicle, and the position of railway line, especially lateral location are more stably fixed thus.Verifiedly particularly in the work of railway line curve, significantly simplified, because also need, considered and compensation level application force.

Accompanying drawing explanation

Other advantages of the present invention are able to clearly by each dependent claims and accompanying drawing.

To describe the present invention in detail by means of the embodiment shown in the accompanying drawings below.Following content shown in the drawings.

Fig. 1 is the lateral plan of safeguarding vehicle of the design according to the present invention, and Fig. 2 and Fig. 3 are respectively the detail view of holding device, and Fig. 4 is an alternative embodiment of the invention.The parts that function is identical are named by identical reference symbol at this.

The specific embodiment

The vehicle 1 representing simplifiedly in Fig. 1 is for safeguarding the railway line 3 with track 2, and can move thereon by means of two track running mechanisms 4.These track running mechanisms are spaced apart from each other and are arranged on framework end 6,7 places of vehicle frame 8 along longitudinal direction of car 5.In the region 9 between these two track running mechanisms 4, under vehicle frame 8, be provided with working space 10, this workplace design is open in the direction towards railway line 3 and is limited by two sidewalls that extend at longitudinal direction of car 11.Sidewall 11 can transversely regulate at railway line by driving according to known way, to can expand as required working space 10.

And then at vehicle frame 8, configure holding devices 13 at each framework end 6,7.Particularly preferably in two holding devices 13 that are laterally being spaced apart from each other of each framework end 6,7 configuration.With reference to figure 2, can more easily find out, holding device 13 is comprised of adjustable for height rail pincers 14, this rail pincers can the pattern of friction lock by means of (preferably hydraulic pressure) clamping actuator 15 and the track head 16 of this track 2 be connected.In addition, at least one in two holding devices 13 is designed to along longitudinal direction of car 5, with respect to vehicle frame 8, to regulate by other actuator 17.For this purpose, at vehicle frame 8, be provided with longitudinal guide part 18, be designed to holding element 19 counter-bending and that reverse and be supported in this longitudinal guide part, this rail pincers 14 is installed on this holding element by highly adjustable, and this holding element himself is connected to longitudinally regulate with the actuator 17 that is designed to hydraulic actuating cylinder 20.

In addition can be also that holding device 13 or rail pincers 14 are not directly disposed at vehicle frame 8 but are disposed at track running mechanism 4 as shown in Fig. 3 (or dotted line) in Fig. 1.In this case, preferably track running mechanism 4 can regulate and is supported on vehicle frame 8 and is connected with actuator 17 at longitudinal direction of car 5, to longitudinally regulate at longitudinal guide part 18.

Fig. 4 shows another embodiment of the invention in very schematic mode, wherein the region of vehicle frame 8 between two track running mechanisms 4 formed by sidewall 11, these sidewalls are laterally adjustable, define working space 10, and be formed into for this purpose thick and heavy especially and firm.Holding device 13 the lower area height of these sidewalls 11 adjustable be connected with these sidewalls, and be designed to along longitudinal direction of car 5, with respect to these sidewalls (that is to say with respect to vehicle frame 8), to regulate by actuator 17 simultaneously.Preferred these two holding devices 13 are configured at utmost spaced apart each other, can remove thus the orbital segment between these two rail pincers 14 with large as far as possible length in work is carried out.

In the work of vehicle 1 is carried out, each track 2 is fixing by means of these two holding devices 13, then orbital segment is cut off.By means of actuator 17, at this, can keep desired track tensioning (push away or draw) or desirable tensile force is applied on track 2 with other correlative factors according to ambient temperature.
