Description

The present invention relates to the field of mechanization of track facilities of railway transport and can be used in the assembly of turnouts, mainly with reinforced concrete beams, at the production bases of track machine stations.

Known stands for assembling turnouts, containing a frame with longitudinal supports for the bars, a marking template for laying out the bars according to the diagram, stops for installing the bars on the "cord", end stops for limiting and controlling the length of the translation, control elements of the translation geometry (ed. USSR No. 142329, ЕВВ 29/26; No. 1093740, ЕВВ 7/00; pat. Of the Russian Federation No. 2007507, ЕВВ 29/24, Е01В 7/00; V. G. Maksimov, E. K. Smykov. Laying and change of turnouts . - M.: Transport. 1993, p. 46-50, 77, 139-143). The layout of the bars according to the diagram, their orientation, the layout of the metal parts are made using cranes and hand tools. The turnout assembly is carried out with a manual and electrified tool.

St. USSR No. 1120050, ЕВВ 29/26) containing devices for receiving and arranging bars according to the diagram and movable along guide assemblies with working bodies for connecting metal parts of the translation with bars. The unit is equipped with a horizontal swivel beam with a rail template mounted on it with template clamps movable along the beam for setting the track. Groups of operations for assembling a turnout switch (laying out the bars according to the diagram and their orientation, laying metal parts on the bars, assembling of a turnout) are performed at one position (stand) sequentially one after another so that the next group of operations is performed after the previous one, which lengthens the overall turnout assembly time, reducing device performance and efficiency.

Known production line for the assembly of turnouts (US Pat. RF №2373319, ЕВВ 29/24, ЕВВ 29/02, ЕВВ 7/00 - taken as a prototype), containing devices for receiving and layout of bars on the plot of the assembled turnout switch and mobile along assembled turnout guide unit with working bodies for connecting the metal parts of the translation with the bars. Devices for receiving and laying out the bars along the diagram include a cargo conveyor for the bars, a device for supplying the bars with fasteners, an assembly conveyor, a device for orienting the bars and delivering them in an oriented position to the assembly conveyor for sequentially moving the beam on it to the step of the diagram. The placement of the working bodies on the unit is not disclosed.

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 performance.

However, the line did not disclose the mechanism for the direct connection of the metal parts of the translation with its bars.

We need a production line for assembling turnouts, where the mechanism for the direct connection of its metal parts with the bars, made using technology (V.G. Maksimov, E.K. Smykov. Laying and change of turnouts, would be disclosed. - M.: Transport, 1993, p.141): fastening with the provision of a track of the straight track rails, setting along the ordinates (distance from the outer rail of the direct track to the outer rail of the conversion curve) and fixing with ensuring the track of the translation curve.

To do this, in the well-known production line for assembling railroad switches, containing devices for receiving and laying out the bars according to the diagram of the assembled railroad switch and a guide unit with working bodies that are movable along the assembly of the railroad switch for connecting metal parts of the translation with the bars, the said unit is equipped with clamps for guides and is equipped with the ability to move along perpendicular to the movement of the unit transverse to its axis with two symmetrically placed relative relative to it, trolleys equipped with wrenches with control panels of the unit, two with the possibility of moving along the transverse axis of rigidly interconnected carriages equipped with rail pushers, with the possibility of displacement along the transverse axis of an ordinate rail equipped with ordinate adjusters, and the assembled translation is equipped with a rail installed along it with setters for interaction with the sensor installed on the unit to stop it.

Carts are equipped with wrenches with the possibility of their transverse movement relative to the longitudinal movement of the cart.

Rail pushers of carriages are vertically movable by means of power cylinders.

The presence in the line of devices for receiving and arranging the bars according to the diagram of the assembled railroad switch and the guiding unit moving with the working assembly that includes the assembled railroad switch for connecting the metal parts of the translation with the bars allows the assembly of the translation to be carried out in a continuous way, performing simultaneously and independently of each other sequential technological operations for accepting the bars, their orientation and layout according to the diagram of the translation being assembled, laying the metal parts of the translation on the beam s, assembly turnout. The equipment of the unit with clamps for the guides allows you to securely fix it when securing the translation. Supply of the unit with the possibility of moving along the transverse axis perpendicular to its movement by two trolleys symmetrically placed relative to it, equipped with wrenches with control panels of the unit, two with the possibility of moving along the transverse axis of carriages rigidly interconnected, equipped with rail pushers, with the possibility of displacement along the transverse axis by an ordinate rail equipped with ordinate adjusters, with the supply of the collected translation installed along it with a rail with sensors for interacting with a stop sensor installed on the unit allows it to reliably fasten the direct track rails with track gauge, reliably set along the ordinates and fasten the gauge rails with track gauge, that is, securely fasten the gear in accordance with its geometry mechanized way with automation of individual operations.

The equipment of the trolleys with wrenches with the possibility of their transverse movement relative to the longitudinal movement of the trolleys allows you to always orient the wrenches to secure the rails with the bars at each next stop of the unit.

The execution of the rail pushers of the carriages vertically movable allows you to move the unit along the translation without affecting the position of the bars for the pushers to interact with the sole of the rails in the space between the bars, and after setting the straight track, move the carriages to set the ordinate and track of the translation curve.

The production line for assembling railroad turnouts contains devices for receiving and laying out the bars according to the diagram of the assembled railroad switch in the form of a cargo conveyor 1 for bars 2 of a railroad switch 3, a device 4 for supplying the bars with fasteners, a conveyor drive 5, an assembly conveyor 6, a device 7 for orienting the bars and distributing them in an oriented position to an assembly conveyor movable along guides 8 assembled along the turnout assembly 9 unit 9 with working bodies for connecting I transfer the metal parts with bars.

A device 4 for supplying beams with fasteners includes lifting tables 10 and 11, a device 12 for laying and attaching fasteners to beams, a device 13 for transferring beams from one lifting table to another, consisting of a console moving along a support 14 into the area of one or the other lifting table 15 with a carriage 16 movable along it with a platform supporting the beam.

A device 7 for orienting the bars and delivering them in a oriented position to the assembly conveyor 6 includes guides 18 mounted on the enclosing conveyor drive 5 and the assembly conveyor 6 portals 18, a carriage 19 movable along the guides 18 with a beam gripper on the drive conveyor 5, orienting it and laying it in an oriented position on the lifting table 20 for subsequent lowering of the beam onto the assembly conveyor 6 to move it to the step of the plot of the dialing set of railroad switches.

The unit 9 with working bodies for connecting the metal parts of the translation with the bars is a portal structure 22 movable by means of running wheels 21 along the guides 8, equipped with clamps 24 driven by the power cylinders 23 for the guides 8 and on which the movable are mounted symmetrically to its transverse axis 25 on the guides 26 on them the carts 27 and 28, equipped with wrenches with control panels of the unit. The wrenches on the carts are made with the possibility of lateral displacement relative to the longitudinal movement of the carts.

Along the transverse axis 25 on the guides 29 are mounted moving along them two rigidly interconnected by a draft 30 of the carriage 31 and 32, equipped with vertically movable by means of power cylinders 33 rail pushers 34.

Also, an ordinate rail 36 is mounted along the transverse axis 25 with the possibility of displacement along it by means of a power cylinder 35, equipped with ordinate gears 37 for interacting with a stop sensor (not shown) and a stop 38 in the outer rail 39 of the direct railroad switch.

The assembled switch is equipped with a rail 40 installed along it with setters 41 for interacting with a stop sensor installed on the unit (not shown).

The line works as follows.

On the freight conveyor 1, the bars 2 are stacked in the order of their placement when assembling the turnout switch, and when the conveyor 1 is stepped, each next beam is fed to the lifting table 10. By the lifting table 10, the beam is lifted, and shock absorbing pads, pads, shoes, are placed on it by the device 12 assembly of embedded bolts is mounted.

After the operations on supplying the beam with fastening elements on the table 10, the console 15 extends along its support 14 along the support 14. The carriage 16 is pushed under the beam 15. The table 10 is lowered to receive the next beam, while immersing the beam on the carriage 16.

The console 15 and the carriage 16 with the beam are moved to the area of the lifting table 11, where by lifting the beam is removed from the carriage. The carriage and the console return to their original position, the beam is supplied with the remaining fastening elements with fixing the linings for the outer rail of the direct path, after which the lifting table 11 the beam is lowered onto the conveyor drive 5 and removed from the zone of the lifting table with a stepwise movement of the conveyor 5.

From the conveyor drive 5, the beam equipped with fastening elements is gripped by the grips of the carriage 19 of the device 7, is oriented by the outer edges of the recesses of the beams of the outer rail of the straight path along one straight line (“along the cord”), by the angle of deviation of the longitudinal axis of the bar relative to the “cord line” and fits onto the lifting table 20, where the orientation of the beam is adjusted and 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 bars of the railroad switch is produced.

On the set of bars of the turnout switch, its metal parts are laid, and the turnout is fixed by the unit 9 when moving it along the guides 8 enclosing the turnout.

First, the straight track rails are fixed with wrench trolleys 27 and 28, the track of which is controlled by the carriage 31 with the emphasis of its rail pushers in the inner rail 42 of the direct track, the control of which, in turn, is controlled by the adjuster 37 of the ordinate rail 36 when the latter stops 38 against the outer rail 39 direct way. Fastening is carried out when moving the unit 9 through the beam so that the wrench trolley 27 secures the bars a1, a2, a3 ... (Fig. 5), and the wrench trolley 28 the bars b1, b2, b3 .... When moving the unit stops 34 are lifted to move through the beam, the emphasis in the bottom of the rail is between the bars. When fixing the unit, it is reliably fixed by its clamps 24 to the guides 8, rigidly fixed on its foundation, which ensures a straight track when fixing the rails of the rails by the 38 ordinate rail and the stop 34 of the carriage 31 relative to the unit frame.

The conversion curve is fixed as follows.

The unit periodically moves with a stop when its sensor interacts with the master 41 of the rack 40 in the places provided by the geometry of the turnout switch. The emphasis 38 of the ordinate rail 36 is moved away from the outer rail 39 of the direct path when moving, and when it stops, it is pressed against it. The fixed outer rail 39 of the direct path serves as the basic element in securing the translation. The carriages 31 and 32, rigidly interconnected, with the raised stops 34 are moved to interact with the outer rail 43 and the inner rail 44 of the conversion curve, respectively. The stops 34 are lowered, the carriages, when moving, shift the rails of the translation curve to the command when the sensor of the carriage 31 interacts with the adjuster 37 of the ordinate rail 36, thus setting the carriage 31 with the ordinate, and the carriage 32 with the track of the translation curve. Wrench trolleys 27 and 28 are secured conversion curve. After fixing the conversion curve at characteristic points, it is solidified.

On the proposed line for assembling railroad switches, the layout of the beams and the connection of metal parts with them are carried out mechanically with the possibility of automating individual operations, thus ensuring efficient and effective work on assembling railroad switches with minimal manual labor.
