Description

one

The invention relates to the mechanization of the collection of stars in a railway track travel, can be applied as an auxiliary mechanism to the collection stands, and is an improvement of the known device described in the author. No. 652257.

Feeder auth. 652257 contains an inclined conveyor, at the end of which there is a receiving tray with hinged shutters on the axles, a cutter mounted at the end of the inclined conveyor and including a cam and an arm with a roller hinged on the receiving tray . In addition, the feeder contains rigidly mounted gears on one x, between which 20 gears are mounted, and a double-arm lever, on one arm of which there is a roller, and on the other - a counterweight, and the lever is rigidly fixed on the axis of one of the gears, and the sash -25 are filled in the form of rollers mounted on axles x 1.

The disadvantage of the design is that the linings that have rounding off the ends in the process of filling 30

the conveyor often ends up facing each other. This leads to failures in operation, since more than one lining can get onto the rollers of the sash panels.

The purpose of the invention is to increase the reliability of the operation of the feeder.

This is achieved by the fact that it is equipped with a similar additional cutter, also hinged on the receiving tray, the distance between the cutters being approximately equal to the distance between the outer edges of the board lining, and their cams are at an angle of 90 ° to each other.

FIG. 1 shows the proposed, feeder, general view; in fig. 2 - the same plan view; in fig. 3 shows section A-A in FIG. one; in fig. 4 is a view along arrow B in FIG. 2; in fig. 5 shows a section B-B in FIG. 2; in fig. 6 - section G-Y in FIG. 2, and in FIG. 7 is a section d-d in fig. 2

The feeder of the liners, when assembling the links of the rail track, when laying them onto the sleepers located along the plot, while moving the shuttle from one assembling position to the assembly stand, has an inclined conveyor 1 with rollers 2 and longitudinal guides 3 installed at such a distance from each other, so that the pads 4 are freely positioned between them. At the end of the inclined conveyor, a receiving tray 5 is installed, on the body of which the shafts 7, 8 are fixed in the sub-supports, and the Folds located on them rollers 9. Shafts 7, 8 carry gears 10 rigidly fixed on them with the same number of teeth, and the center-to-center distance between these axes closes two gears 11, 12, due to which gears have the opposite direction of rotation. Depending on the direction of movement of the sleepers on the starboard stand on the axis of one of the two wheels, a twin-arm lever 13 with a roller 14 and a counterweight 15. On the case 6 of the receiving tray 5, the cutter 16 is attached, which includes a cam 17 fixed to the shaft 8 and - the plane with it is the roller 18 of the lever 19, hinged on the axis 20 of the bracket 21 ,. mounted on the housing 6. On the opposite side, the lever 19 has a protrusion 22 for holding the linings behind the front flange. At a distance slightly exceeding the distance between the outer edges of the front and rear ribs of the insert, a similar additional cutter 23 is installed from the shutter 16, with the cam 17 of the shutter 16 and the cam 24 of the shutter 23 located at an angle of 9 Friend to each other.

The design feature of the latch cutters is a sufficiently large displacement of their protrusions 22 towards lining 4 for lever 19 (and from the lining up for lever of cutter 23) already at a small angle of rotation of the shaft 8, which is carried out by the used design of cam profile elements. The gear ratio between gears 10 and wheels 11, 12 is chosen as such. so that the full opening of the valves is achieved at a small angle of rotation of the lever 13. The gears 10 and the wheels 11, 12 can be made in the form of gear sectors, since they only work with part of their circumference, there is a stop 25 for the liners at the end of the receiving tray.

The device works as follows. The pads 4 are directed to the rollers 2 of the inclined conveyor 1 and under their own weight rush down towards the tray 5. When the rollers 9 are horizontal, the lever 19 with its protrusion 22 secures all the pads lying behind, and the front lining on the rollers 2 rolls into the tray 5, the access stop 25 (the slam-shut 23 is in the upper position). The shuttle sleeper 26 is moved by the lever 13, which, through a system of kinematically interconnected wheels, causes the rollers 9 to quickly turn downwards, and the lining 4 lying on them falls onto the cross sleeper. In this case, the protrusion of the shutter 23 is in the lower position, and the protrusion 22 of the shutter 16 is in the upper and not

0 holds the pads so that they can roll to the protrusion of the shutter 23. The slider moves further beyond the limits of the motion path of the roller 24 and the counterweight 15 ry /: the chuck 13 rotates into the original

position, and the rollers 9 of the receiving tray will occupy a horizontal position. By the time of their stopping in this position, the protrusion of the cutter 23 does not hold the next lining 4, which rolls onto the rollers 9. The protrusion 22 at this time is in the lower position and delays the movement of the pads into the space between the cutters 16 and 23. Then the process repeats .

Feeder lining ensures reliable operation when assembling the links of the track.
