Description

one

The invention relates to railway machines used for the construction and repair of railway tracks and can be used for continuous ballasting of the track.

The track machine is known, containing the undercarriage, the frame mounted on them and the bearing mechanism mounted on it with electromagnets, the mechanism of continuous tamping and its lifting mechanism 1.

However, in this machine, the transmission of vibration to the frame during the operation of the continuous tamping mechanism is not excluded.

In this connection, according to the current sanitary standards, the time of work of the machine is limited to 75 work shifts per year with a prolonged work shift of not more than 2 hours.

The purpose of the invention is to increase the vibration resistance of the machine.

To do this, in the proposed machine, the lifting mechanism includes power cylinders, the rods of which, by means of flexible tubes, are connected to a continuous tamping mechanism installed on a rail carriage and coupling

with the frame by means of the troso-block system, the blocks of which are fixed on the frame.

At F1B-. 1 shows the track machine, a general view; in fig. 2 - mechanism and preligation tacking, top view.

The track machine comprises a frame 1 supported on the undercarriage 2 moving along a raised path, the undercarriage 3 moving along the subsurface path and connected with the frame 1 with an offset to the undercarriage

0 trolley 2 mechanism 4 alignment of the path with elvktro magnets. Between the mechanical alignment 4 track and the undercarriage 2 to the frame 1 suspended mechanism 5 continuous podbivka path containing rail carriage with frame 6, vibrots drive 7, interacting with tamping plates 8 and wheels. 9 of the rail car and connected to the frame 1 by means of a troso-block system 10, the blocks 11 of which are fixed to the frame 1 through the shock absorbers 12.

20 The lifting mechanism comprises power cylinders 13, the rods of which are connected to the mechanism 5 of continuous tamping by means of flexible t g 14.

The ballast dosage is made by the dispenser 15, and the sleepers and rails are cleaned from the ballast by the rail-rail brush 16 connected to the frame 1 shifted to the undercarriage 3 moving along the same path, and the ballast is laid out under the sleepers during lifting. the rail track is manufactured by ballast frames 17 with strings 18.

In the working position, the pulling force of the track machine through the frame 1 is connected to the mechanism 5 of continuous tamping of the track, which with a certain effort by the traveling wheels 9 presses against the rails without transmitting vibration to the machine, thereby increasing its vibration resistance and service life.

For continuous ballasting of the track of the machines, it is established at the end of the raised portion of the track by the mechanism 4 of the track alignment in the direction of the upper stretch. The track grid is mounted on the compression height of the ballast layer, and the machine starts moving in the direction of the upstream section of the track.

When the maschine moves, the ballast is metered into the path with a dispenser 15. The sleepers and rails are cleared of ballast by ishalno-rail brushes 16 on curvilinear paths of a small radius due to the displacement of the brushes to the undercarriage 3. The alignment mechanism 4 makes a simultaneous continuous process of posting. from the side of the track rover to the height of the ballast layer. The ballast is supplied under the sleepers by the strings 18 and compacted by squeezing the track grill by the continuous tamping mechanism 5 by vibrating drive 7 on the tamping plates 8 and the running wheels 9 with the ballast bulk seal on the side of the sleepers and vibrating the track grids into the ballast due to forced vibrations at the impact of the traveling wheels 9 of the mechanism 5 for continuous tamping with the elimination of the deformed half-wave noff on that side by means of the grating at the reduced length of the free span of the frame 1.

With a decrease in the length of the free span of the frame 1 with the offset mechanism 4 bearing

the path and mechanism 5 of continuous tamping of the path to the undercarriage 2 is ensured by their operation in curved sections of the path of a small radius.

The transfer of the machine to the transport position at the end of the work is as follows.

The track alignment mechanism 4 and the continuous tamping mechanism 5 by the action of lifting hydraulic heads 13 on the flexible rods 14, the dispenser 15, the slurry rail brushes 16 and the ballaster frames 17 are raised to the upper position. The transfer of the machine from the transport to the working position occurs in the reverse order.

Thus, the set of operations for ballasting the path, proposed by the machine, which were previously performed by separate machines, both cyclic and uninterrupted, is performed by lifting, metering, tamping, leveling and tamping and treating.
