Description

Podshtopka and tamping railway sleepers, the purpose of soil compaction (with black repair) or ballast under the sleepers, are among the most labor-intensive operations in the general trackwork complex. In orpoiMHoM, in most cases, linings and tamping work are done manually. With the help of a hand or pneumatic (less commonly electric) tool. The existing constructions of the tamping machines, which copy, in essence, the manual process of the tamping, require long installations in each group of sleepers and, therefore, have low permeability. Therefore, the tamping machines of existing structures did not receive wide distribution.

Meanwhile, the introduction of high-speed metods for the construction, reconstruction and (repair of the railroad track, the use of high-performance machines and equipment on the track works (self-discharging trains, ballasts, track-laying machines, etc.) urgently requires a sharp increase in the productivity of under-pitched pivot work. The manual method production of these works, even with significant quantities of labor, small portable tools, p. power plants, etc., can not provide the desired performance. To that, the issue of creating a continuous under-heading machine with high productivity is urgent and needs to be resolved.

The daily inventions have to replenish this lobel with the help of the proposed tamper machine of continuous operation, which with the planned performance of about 5 lg {/ hour is designed to ensure a uniform seal under all the sleepers, regardless of the thickness of the latter, with the possibility of simultaneous alignment of the path level and eliminate distortions. At the same time ballasting (soil) is supposed to be made by the machine only in the areas where the rail lines are located, which is most beneficial for the operation of the sleepers. For this purpose, each vibrating compactor of the machine is made in the form of a horizontal rotating disk. To remove the same ballast from under the ends of the sleepers and to feed it back, the disks from the outside are enclosed with plows.

In FIG. 1-3 depict the general view of the machine in the working position (in three projections); FIG. 4 and 5 - details of the device; FIG. 6 - Tartsev view of the car in the transport position.

The proposed tamping machine ciocTlOHiT from a metal frame with a normal railway movement, carrying a row of metal plows 3, 4, 5 (Fig. 1 and 2) attached With vertical posts to the side beams; .paiuLbi designed for ballast dumping (gruyt) from under sleepers and the subsequent backfilling of voids. On the swivel arms, axle-mounted rotary sealing discs 6, 7, 8 are attached to the beams of the frame; they are mounted inside their vibrator: 16 (Fig. 5) and with individual flange electromotors to drive the vibrators. For co daadley drives on. serve as tension springs :, s aklyuch, each in a separate cup 9 (Fig. 4), attached to the frame 1 and KpoHmiie.HJHiy disk.

The drill is also equipped with vertical limiting rollers 13 with adjusting screw fur of base 14 (fig. 1.6), pa) with hovering over head rail rails and the same set | for lifting height adjustment. The production of electromotor vibrators of the production of | D | Its from a geyutortnoy installation, -consistent of the internal combustion chamber and reHeipaTopa constant tsysa. For the installation of plows 1,2 in olarychitelnyh shields 10, 11 serves as the edge of a yoke with a hoist 12.

The installation of all the working parts of the machine from the vehicle with the transIortnopo: SOSTOMSHE into the working one and back is carried out with the help of hand drives (in gear, rails, hand hoists). The movement of the machine when carried out by pulling or pushing it with a locomotive at the speed of 5-8 KAijiac. In the working position (p. 1-3), the working bodies of the machine are not within the limits of the size of the rolling stock (not (pre; n; however, movement along the railway track on double-track sections. In the transport position of the machine (Fig. 6) all mechanisms and working organs are removed within the limits of the envelope.

The rabbedag machine is carried out as follows. Previously, ballast (bulk) is removed from the ends of 2-3 sleepers at the place of commencement of work. In the vacated space (under the sleepers) at the water outlet, the ends of the plows 1 and 2, followed by the last, were fastened on columns at an angle of 30-35 ° to the axis of the track. Then the machine advances somewhat forward, as a result of which the pluri 1.2 ejects ballast from the end of the beam. So freed; At the same time, the space under the sleepers is a plant and compacting disks 6, 7, 8 of the first (the ends of the plows 3, 4, 5.) are fixed to the frame through stacks 9 springs (Fig. 4), and the plows 3, 4 and 5 are mounted on columns at respective angles to the axle of the track. After installing the lugovs, the crane with the hoist 12 is fed to the ends of the plows attached to the ends of the shields: shch 10 from the side and the shield 11 from the field side. the watchman of the machine is installed. At the same time with the installation of shields, the vehicle is lowered to the bottom in the rails of the limiting rollers 13, carried out by screw mechanisms 14. This completes the charging for work. With the beginning, the working movement of the machine (Forward, electric motors 15 are turned on, causing unbalanced loads (vibrators) 16 (Fig. 5), Situated on the outskirts of dizsk. When moving the bus / tire, the following happens: Plows 1 rake out ballast from under the END pinch and move it from side to side between shield 10, and from field side to shield 11. Plows 2 pull And toward shield 10 and 11 ballast, showered with sleepers And from the sleeper cabbage FORWARDS TO BE CARRIED OUT 1. Discs 6 roll the ballast under the sleepers, creating a horizontal vibratory pressure in the location area (rail threads, while discs 7, Walking a little closer to the axis of the track) With discs 6, they create additional reinforcement under the ballast. sleepers in the area of the rails. The plows 3 feed a portion of the shifted plows 1 and 2 of the ballast under the ends of the dips, and the plows 4 shift the excess ballast and the ballast caught in the sleeper boxes to the shields 10 to P. Disks 8 create a seal in an additional portion of ballast supplied by the plows 3 and (Finally, the plows 5 shift the entire balance of ballast selected from under the sleepers to the axis of the path, the MI left free after passage of the discs 8 under the sleepers, the ends of the sleepers and the sleeper ribs and the ballast profile (or ground plane) are filled. Thus, after Passage machine s ballast d sleepers in rail arrangement It appears densified zone and ballast section Voss and copulating in the original form.

When the ballast is compacted by vibrating discs 6 and 7, the pressure spreading in the ballast tends to raise the sleepers, and hence the entire path. However, restrictive rollers 13 prevent this from transmitting part of the weight of the machine to the rail tracks. If using mechanisms 14 slightly raise the rollers 13 or ofliKtt from "THEIR over the rail head," the pressure spreading in the ballast will raise the path: By the size of the gap between the rollers 13 and the heads of the rail, thereby lifting the path. Since the clearance

between the rollers 13 and the rails can be adjusted quite smoothly by the mechanisms 14, then the lifting (alignment) of the track by the machine can be carried out quite accurately. Thus, the degree of compaction of the ballast under the sleepers is determined solely by the tension of the springs 9 and the number of revolutions of the loads of the vibrators 16 and does not depend on the thickness of the sleepers, which ensures a sufficiently uniform compaction of the ballast under all the sleepers of the track, eliminating the need for souls.

The width of the compacted ballast zone can be adjusted by appropriate transverse installation of plows and discs.
