Abstract

The aim of the invention is to provide a self-propelled rail vehicle for setting up poles in a rational manner. The self-propelled rail vehicle has two triple-axle bogies (2) on the track (1). It has a cab (3) for the operating staff and a movable balance weight (4), while a crane (5) is also fitted on the load platform. The crane (5) has an extending jib (6). The crane (5) can be transferred from one turntable to the other. One goods truck loaded with poles is coupled in front of and another behind. Owing to its positioning facilities, the crane can reach first one truck and then the other.

Description

Technical field

BACKGROUND OF THE INVENTION The invention relates to a rail vehicle for supporting pillars, preferably on both sides, with a coupling device for connecting freight wagons, on which a crane is positioned, which is positioned in the region of each connected freight wagon

BACKGROUND OF THE INVENTION

Up to now, the columns have been laid in such a way that a crane or a suitable mobile crane is mounted on the freight wagon. A wagon with a crane and a freight wagon with a locomotive are a work train. It is disadvantageous here that the freight wagons loaded with different masts must be moved so that the mast wagon is always connected to the crane wagon. As is generally known, disconnection on open track is prohibited or impossible, especially when the track is inclined. Therefore, the secondary track must be closed during the erection of the columns.

A rail vehicle of this type is known from GB-PS 2 218 398. The freight wagon located between the locomotive and the wagon with the crane must always be replaced only on the shunting rail. Therefore, the crane unloading for positioning the mast over the driving profile in the siding also came out. Further, a rail vehicle with a crane is known from EP-A 0 064 896, in which a sliding counterweight is arranged transversely to the longitudinal axis.

SUMMARY OF THE INVENTION

IN

SUMMARY OF THE INVENTION The object of the present invention is to provide a rail vehicle which, on the one hand, does not have the above-mentioned disadvantages and, on the other hand, makes it possible to rationalize the placement of columns.

The rail vehicle according to the invention is characterized in that it is self-propelled and is provided with transverse balancing weights transversely to the longitudinal axis and maintains the driving profile or the loading gauge with respect to the siding during the working procedure.

J

It is only with the aid of the invention that the work required to support the columns can be carried out economically. By means of the invention, at least two freight wagons loaded with poles can be conveyed and the poles can be manipulated on two freight wagons without wagon switching. The freight wagon is suspended in front of and behind the self-propelled rail vehicle. By positioning the crane, the crane can extend once to the first carriage, and to the second carriage. When it is expected that the individual columns will weigh up to 10 tons, a 75 mt crane is required. To prevent the vehicle from tipping over when the crane is rotated during the working procedure, the vehicle is fitted with a sliding counterweight. Then the crane has no lining upstream and maintains the southern profile with respect to the siding. As a result, undisturbed railway operation is possible on additional rails.

Therefore, precise positioning of the pillars is possible, with the self-propelled rail vehicle being operated and controlled by only one person.

According to another embodiment of the invention, the rail vehicle has two three-axle bogies. Since the 75 mt crane has an extremely high axial pressure, a multi-axis must be used for compliance

i chassis.

According to a further feature of the invention, the balancing weight * is located on the bearing surface. This ensures a compact construction of the rail vehicle.

According to another embodiment of the invention, the balancing weight is placed in an optionally on the vehicle frame. This can greatly increase the stability of the vehicle.

According to a further feature of the invention, the pH of the load suspended on the crane arm in the lateral, running position of the rail vehicle or the whole train is possible. This minimizes downtime.

According to a further feature of the invention, the column support work can be carried out at a continuous conveying capacity. This is particularly advantageous when the work on the columns is carried out at the edges of the station.

According to another embodiment of the invention, the crane is rotatable 360 ° about its own axis. So maybe the work is seen from the wagon on both sides.

of the drawings

The invention is further elucidated by means of an exemplary embodiment shown in the drawing, which shows a side view of a rail vehicle according to the invention.

DETAILED DESCRIPTION OF THE INVENTION

According to the figure, a rail vehicle with two three-axle bogies 2 is mounted on the rails. In the front and at the rear, freight wagons loaded with columns can be attached to the rail vehicle. To position the crane 5, the crane 5 may be movable from one triaxial bogie 2 to the other three-axle bogie 2. The operator's cab 3 may also be located at the other end of the rail vehicle.

Instead of this solution, for example, the vehicle may be divided into a pivotable upper wagon and a low loader, or the whole vehicle may be rotated on a turn.
