The disadvantage of the tractor-metering tractor is the complexity of the design, as well as the limited range of application.

The utility model is based on the task of improving the design by using a modern industrial basic tractor with a hydrostatic transmission, equipped with a combined track, soil and rail, installing loosening equipment equipped with mounts for rods and couplings, as well as ensuring the possibility of hanging bulldozer equipment, excluding from the tractor design mechanical creeper.

The technical result of the claimed utility model is to simplify the design and increase its reliability.

The technical result is achieved by the fact that in a tractor-metering tractor, including a base tractor, a pushing frame, hinged to the frames of the tractor caterpillar bogies, with a turn in a vertical plane, a frontal shield, side wings, hinged to the frontal shield, with a turn in a horizontal and vertical planes, the base tractor is made with a hydrostatic transmission and is equipped with a combined course, unpaved and rail, behind the base tractor, loosening equipment is installed.

Additional support rollers are mounted on the inner beams of the crawler carriage frames. The ridges of the shoes of both track chains have cutouts for the rails. On the supporting surfaces of the shoes, guide ridges are welded to prevent the tractor from derailing.

Additional holes are made in the shoes for rearrangement of the track shoes of the base tractor.

The ripping equipment is equipped with fasteners for mounting rods and couplings.

The tractor is designed with the ability to hang bulldozer equipment.

Thus, the claimed implementation of the tractor-metering tractor provides a simplification of the design and an increase in its reliability.

The essence of the utility model is illustrated by drawings, where Fig. 1 shows a general view of a tractor-metering tractor with metering and loosening equipment; in fig. 2 shows a running group, tracked carts, a tractor-metering tractor; in fig. 3 shows a loosening equipment with an attached linkage for coupling with a track bogie; in fig. 4 shows a loosening equipment with an attached coupling device for coupling with a railroad car; in fig. 5 shows a rail track; in fig. 6 bulldozer equipment.

The tractor-metering tractor contains a base tractor 1, a pushing frame 2, pivotally attached to the frames 3 of tracked carts 4 of tractor 1, with a turn in a vertical plane (not indicated in the drawing), a frontal shield 5, side wings 6, hinged 7 to the frontal shield 5, with rotation in the horizontal and vertical planes (not indicated in the drawing). The basic tractor 1 is made with a hydrostatic transmission (not indicated in the drawing) with final drives 8 and is equipped with a combined course, a dirt track 9 and a rail 10. Ripper equipment 11 is installed at the rear of the basic tractor 1.

On the inner beams (not indicated in the drawing) of the frames of the caterpillar trolleys 4, twelve additional support rollers 12 are mounted. shoes 13, guide ridges are welded on (not indicated in the drawing), preventing the derailment of the tractor 1 from the rails 16.

On the inner surface (not indicated in the drawing) of the shoes 13, plates 17 are welded on, along which additional support rollers 12 roll, for rail travel 10.

In the shoes 13 additional holes 18 are made for rearranging the shoes 13 of the track chains 14 of the base tractor 1.

The loosening equipment 11 is provided with fasteners 19 and 20, respectively, for mounting a pull rod 21 for coupling with a track bogie 22 and mounting a coupling device 23 for coupling 24 with a railway car (not indicated in the drawing).

The tractor 1 is made with the possibility of hanging the bulldozer equipment 25.

The tractor tractor-metering unit operates as follows.

Hydrostatic transmission (not indicated in the drawing) with final drives 8 of the base tractor 1 provides a stepless change in traction and speed characteristics, increases the resource and reliability of components and assemblies of the power plant (not indicated in the drawing) of tractor 1, due to the lack of mechanical connection between the engine (in the drawing not indicated) and transmission (not indicated in the drawing), as well as the absence of the need to install additional devices, for example, mechanical creeper.

The tractor-metering tractor has the possibility of an end drive onto a railway track using ramps (not indicated in the drawing), butted to the ends of the rail heads 16, as well as a side drive.

The movement along the railway track is provided by the rail track 10. For this purpose, twelve additional track rollers are mounted on the inner beams of the frames of the caterpillar bogies 12. In the ridges of the shoes 13 of both track chains 14, cutouts are made 15. On the supporting surfaces (not indicated in the drawing), the shoes 13 are welded on guide ridges 17, preventing the derailment of the tractor 1 from the rails 16.

The transfer of a tractor-metering tractor from a track of 1520 mm to a track of 1435 mm consists in the conversion of the track chains 14 of the base tractor 1. For this purpose, additional holes are drilled in the shoes 13 18. By rearranging the fastening (not indicated in the drawing) of the shoes 13, relative to these holes 18 to the links of the track chain 14, a track change occurs. All shoes 13 slide inward to the longitudinal axis of the tractor-metering tractor for work on rail tracks with a track gauge of 1435 mm.

Dosing equipment, which includes a frontal shield 5 and side wings 6, hinged 7 to the frontal shield 5, allow you to rotate in the horizontal and vertical planes, as well as the installation of side wings 6 both forward at the required angle and backward, depending on the ongoing operation to dose the track and finish the ballast prism.

To perform an adjustable cut of the ballast layer to a predetermined height, the side wings 6 are deployed, brought together into a triangle, combined using a regulating device (not indicated in the drawing). With a normal inclination of the frontal shield 5, the cut surface of the ballast should not have a depression in the middle part and the frontal shield 5 should not collect ballast in front of itself.

To pass the curves of a small radius of the railway track on the front shield 5 relative to the rail head 16, the width of the cutouts (not indicated in the drawing) for the rails 16 is increased.

A tractor-metering tractor can be used as a traction rolling stock for performing shunting operations in the construction of railway tracks, capable of moving a railway train weighing up to 600 tons along the track on railway tracks with slopes of no more than 2 degrees. For this purpose, attachments 20 are provided on the loosening equipment 11 for mounting a coupling 23 for coupling 24 to a railroad car. Adjustment of the position of the hook in height relative to the counterpart of the hitch 24 of the car is carried out by raising or lowering the ripping equipment 11.

The track carriage 22 with the located links of the rail and sleeper grate (not indicated in the drawing) is connected by the rod 21 to the fasteners 19 of the loosening equipment 11 for transportation.

The loosening equipment 11, mounted on brackets 26 behind the base tractor 1, can provide various versions. The lifting and lowering of the 11 ripping equipment is carried out using the hydraulic cylinder 27.

Depending on the tasks to be solved, the basic tractor 1 is made with the possibility of hanging bulldozer equipment 25, for example, in the form of a blade, for the development and movement of the soil of the subgrade. A lifting device is used for the assembly and disassembly of the bulldozer equipment 25.

In the proposed tractor-metering unit, the effect of simplifying the design and increasing its reliability is achieved through the use of a modern basic tractor with a hydraulic transmission with final drives and a combined track, unpaved and rail, ensuring its movement at any speed within the specified range without installing mechanical creepers.

The proposed tractor-metering tractor can be used for metering various types of non-frozen ballast into the track (on wooden and reinforced concrete sleepers), filling the sleepers with ballast, ballast prism mandrel, cutting off the ballast layer, clearing the track from snow, feeding the links of the rail sleepers with a track cart under tracklayer, as well as performing shunting works in small volumes during track works, for the development of soils of categories I-IV and their movement during the development of excavations, the construction of embankments, the construction of trenches and pits, performing planning works, backfilling and cutting benches on slopes, preliminary loosening of rocky and frozen soils.
