Abstract

1. PACKAGING UNIT containing a frame mounted on the undercarriage, racks hinged on the frame with the possibility of rotation in a vertical plane, boom hinged on the racks, gripping devices mounted on the boom and the link travel mechanism. characterized in that in order to expand technological capabilities by providing work on curvilinear sections of the small ra, tius path, it is equipped with consoles fixed in the front part of the frame with the possibility of limited rotation in the horizontal plane, and support rollers to support the link of the track mounted on consoles with the ability to rotate in a vertical plane in the direction to the longitudinal axis of the aggregate, and the mechanism for moving the ten-link link is mounted on the frame. 2. An assembly according to claim 1, of which is that the racks are connected with the drives of their rotation by means of sliding supports.

The invention relates to the construction of railways, and more specifically to the construction of machines for disassembling and laying railway tracks pre-assembled and parts, mainly in industrial and municipal rail transport. The purpose of the invention is the expansion of the technological capabilities of the unit by ensuring the production of works on curved sections of a small radius path. FIG. G shows the track-laying unit, general view; in fig. 2 view L in FIG. one; in fig. 3 is a view of FIG. 1 (on the console part of the unit with the horizontal and vertical position of the rollers); in fig. 4 shows a section B-B in FIG. 1. The track-laying unit contains a frame 1 mounted on the undercarriage 2. On the frame 1, two pairs of pillars 4 are pivotally fixed by a drive 3 in a vertical plane, supporting boom 5, on which cargo winches with gripping devices are mounted. Between the pillars 4 on the frame 1 there is a table 7 movable along the unit, the movement of which is served by a chain conveyor 8 with a drive 9, which is the mechanism for moving the link along the unit. Screen-mounted platform 10 is equipped with an identical conveyor and additionally a lift (not shown) for hanging packages of 11 links above the conveyor 8. At the front ends of the side frames of the frame 1 are pivotally fixed consoles 12 with the possibility of their limited rotation in a horizontal plane, for example, by means of a hydraulic cylinder (not shown) . The support rollers 14 are installed on the console x12 by means of the bracket 13, which can be rotated from the horizontal position to the vertical and backwards in the direction to the longitudinal axis of the unit. The rotation drive of the rollers can also serve as a hydro cylinder. The pillars 4 are connected with the drive 3 of their rotation by means of sliding supports 15, which provide for the lowering of the boom 5 to that and the other 92 sides from its critical position. Under the package of 11 links hung over the crane platform 10 by means of conveyor 8 with drive 9, table 7 is lowered and the lower link in the package is lowered onto it, after which table 7 is moved to the zone of operation of devices 6. I By turning racks 4 by means of drive 3 gripping devices 6 cargo winches are installed above the link so that the latter is conventionally divided into three equal parts, after which the link is grabbed and lifted, the table 7 is moved to the covered platform for loading the next link, the rollers 14 by rotating the bracket 13 in the vertical Flax plane mounted in a vertical position and found to luminant in 6 x gripper unit is lowered onto the track. Before outputting the table 7 with the next link to the cantilever part 12 of the frame 1, the gripping devices 6 rise above the surface of the frame 1 to a height of 1 m, and the rollers 14 are set to a horizontal position, which corresponds to bringing the track-laying unit to the position for repeating the next cycle, and the rollers 14 support with this link path. To bring the unit into the transport position, the console 12 is rotated in a horizontal plane until the front ends touch at a point above the longitudinal axis of the track, and the boom 5 is rotated by the racks 4 by the actuator 3 to a position in which its ends do not extend beyond the frame length 1 console 12. To achieve the desired angle of rotation of the uprights 4, providing the required amount of movement of the boom 5 over the frame 1 in the horizontal. In the horizontal direction, hydraulic cylinders with a traditional stem attachment to a moving object cannot be applied due to the limitation of the stroke of its piston. Therefore, it is necessary to use sliding bearings 15, which provide significant angles of rotation of the uprights 4 with limited values of the stroke of the pistons of the hydraulic cylinders.

So, when you rotate the stand 4 against the hour arrow (Fig. 1) before it is installed in a vertical position, the left support 15 moves along the stand to its top until it stops, and the further turn of the stand 4

is carried out under the action of the self-weight of the boom 5 with cargo .1 winches, and the right (Fig. 1, the support 15 moves along the rack 4 to its base.
