In addition, the pairwise installation of the chain transmission branches on its frame allows constructively dividing the conveyor into two large parts for the possibility of transportation with subsequent facilitation of installation. The supply of the conveyor flooring allows you to secure the work of maintenance personnel during assembly work, protecting them from the possibility of falling through between the bars.

A device 6 for orienting the beams and delivering them in a oriented position to the assembly conveyor includes guides 35 mounted on the enclosing conveyor drive 22 and the assembly conveyor 5 portals 35, a carriage 36 movable along the guides 35 with a beam gripping device on the drive conveyor, orienting it and laying in an oriented position on the lifting table 37 for subsequent lowering of the beam on the assembly conveyor 5. Arranged similarly to the lifting tables 18 and 19, the lifting table 37 is additionally equipped with a device th position adjustment based boards.

The trolley 8 with working bodies for connecting rails and other metal parts of the translation with the bars is a portal construction with sliding guides along the enclosing conveyor 5 guides 7 with devices for controlling the track straight line, controlling the ordinate of the transfer track, clamping the bars to the rails, screwdrivers for tightening the fastening nuts .

The cart 9 for cleaning the blocks of assembled turnouts is a portal construction that is movable along the enclosing assembly conveyor 5 and guides 7, equipped with vertically movable grippers 38 behind the rails of the turnout block.

The line works as follows.

Bars 2 are stacked on the cargo conveyor 1 in the order of assembly of the right-hand or left-hand translation 3. Four branches of the conveyor 12 with platforms supporting the bars 17 allow placing sleepers and all types of bars of the corresponding length on it, while the center of gravity of each beam will be inside between its extreme supporting surfaces, which ensures its stable position on the conveyor when supporting the beam, respectively, on two, three or four of its branches.

With a conveyor belt 1, each beam is alternately, when the conveyor is moved stepwise, onto the lifting table 18. The lifting table 18 lifts the beam and the device 20 stacks shock absorbing gaskets, linings, shoes, and assemblies of embedded bolts are mounted. The process is controlled by the operator, placed on the supporting platform 23. The rise of the beam by the lifting table 18 is carried out to a height convenient for the operator.

After the end of operations for supplying the beam with fasteners at this position, the console 26 of the device 21 for transferring the beam from one lifting table to another is extended to the area of the lifting table 18 along the support 25. On the console, under the beam, the carriage 27 is approaching. The table is lowered to receive the next beam, while immersing the beam on the carriage 27 (a) -b) of Fig.6).

The console 26 and the carriage 27 with the beam are moved to the area of the lifting table 19, where by lifting the beam is removed from the carriage. The carriage and the console return to their original position. The beam on the lifting table 19 is provided with the remaining fasteners and the linings for the outer rail of the direct track are fixed on it, which is controlled by the operator placed on the supporting platform 23 of the zone of the lifting table 19. After that, the lifting table equipped with fastenings the beam is lowered onto the conveyor drive 22 (g) -e) 6). When moving the conveyor drive 22 stepwise, the beam is removed from the zone of the lifting table 19.

Work on the reception of the beam by the lifting table 18 and its supply with fasteners in the area of the beam and the work of supplying the beam with fastenings in the area of the lifting table 19 with the delivery of the fastened beam to the conveyor drive 22 to remove it from the working area of the lifting table 19 are performed simultaneously and independently of friend, while the work is carried out in a convenient zone for operators.

From the conveyor drive 22, the beam equipped with fastenings is gripped by the grippers of the carriage 36 of the device 6, oriented along the “cord”, i.e. it is guided by the outer edges of the recesses of the bars for the outer rail of a straight path in a straight line, it is guided by the angle of deviation of the longitudinal axis of the beam relative to the "cord line" and fits onto the lifting table 37, where the beam is finally adjusted according to the "cord" and the angle of deviation from the "cord line" . The beam is lowered onto the assembly line. The oriented beam by the assembly line is shifted by the step of the plot, a set of the turnout bars is set.

The work on supplying the beams with fasteners and the work on the selection of a set of bars of the turnout switch due to the presence of the conveyor drive is carried out simultaneously and independently of each other.

As the bars of the turnout switch are assembled by the assembly line, rails and other metal parts of the translation are laid on them. Trolley 8 when moving it along the guides 7 enclosing the assembly line, the railroad switch is assembled.

After checking the assembled translation, it is divided into blocks, at the same time the set of bars of the next turnout continues. The assembled turnout unit closest to the docking station 10 is captured by the grippers 38 of the trolley 9 and the trolley 9 along the guides enclosing the assembly conveyor 7 moves the block to the docking station 10. At the docking station, the block is stacked on an overpass 11, the height of which corresponds to the height of the assembly conveyor, thereby minimizing vertical moving the block when cleaning it from the assembly line.

The assembly line continues uninterruptedly - a set of bars of the next turnout is recruited, the next assembled turnout unit approaches the loading platform, which is removed to the loading platform as it approaches.

Blocks of assembled turnouts are removed from the transshipment site to a finished goods warehouse.

On the proposed line, certain groups of technological operations for assembling turnouts are performed simultaneously and relatively independently of each other, which allows assembling turnouts in a continuous way with high line productivity most efficiently and with the highest possible mechanization and automation of individual operations.
