Description

The present invention relates to the field of mechanization of track facilities of railway transport and can be used in the assembly, disassembly, repair of links of the rail-sleeper track lattice at the production bases of track machine stations.

A device is known for working with rails when laying them on a set of sleepers of a link on a link assembly line according to US Pat. RF №2285080, ЕВВ 29/24, containing four portals with carriages driven along the chains by means of chains, equipped with lifting-lowering grips under the sole of the rails. Gripping under the sole of the rails is only feasible for freely lying single rails and is not feasible if there are adjacent rails. The presence of four portals complicates the design of the device.

A device is known for laying rails when assembling links and removing rails when disassembling links on link assembly, link sorting, and link repair lines (ed. St. USSR No. 1451080, B65G 35/08, ЕВВ 29/24; Pat. RF No. 2210654, ЕВВ 29/24 , B65G 25/04, 35/08; pat. Of the Russian Federation No. 2304190, ЕВВ 29/24; E.T. Lonchakov, B.P. Petropavlovsky. Track machines for link assembly and link sorting. - M.: Transport, 1984. - p. 158-159, Fig. 132), containing two portals with traveling trolleys moving along their driving beams, equipped with a traverse with grips for the rail head. The traverse is suspended to the running trolleys by means of hydraulic cylinders. The grips are also equipped with hydraulic cylinders for mixing-breeding their gripping legs. To drive hydraulic cylinders, a pumping unit is mounted on the traverse. Traveling trolleys for their movement are equipped with a cable block system from drives installed on the portals.

Two portals are enough to capture the rail and its transverse transfer. The portals are spaced relative to each other so that the deflections of the captured and posted rail are uniform everywhere - in the middle between the grips and at its ends-consoles. The equipment with hydraulic cylinders of the traverse for its raising-lowering and grips for information-breeding of gripping legs allows you to automate these processes. The equipment of the running trolleys for their movement by the cable-block system from the drives does not guarantee their exact stop when pointing the beam to capture the rail and lay it.

A device is known for working with rails on link assembling lines (US Pat. RF No. 2116398, ЕВВ 29/24 - taken as a prototype), containing two portals with running trolleys moving along their driving beams with a traverse attached to each of them with a grip for the head rail in the form of L-shaped hooks, rotatable 90 ° along and across the rail head. The device for attaching the traverse to the running trolleys is not open, the rope is depicted, which determines the swing of the traverse when it moves and stops. When the beam is attached to the trolley by means of a hydraulic cylinder, it is limited to its stroke. The installation location of the pumping unit for the drive of the hydraulic cylinders of the L-shaped hook hooks has not been determined.

What is needed is a device for working with rails on assembly lines, containing two portals with running trolleys moving along their driving beams with the possibility of their smooth pulling away and a smooth exact stop with a hydraulic cylinder attached to each of them, but with a stroke longer than the hydraulic cylinder , a traverse equipped with a vibration damper and a grip on the rail head in the form of L-shaped hooks, rotatable 90 ° along and across the rail head for gripping and releasing the rail head in the presence of a number house of rails located.

To do this, in the known device for working with rails on link assembly lines, containing two portals with traveling trolleys moving along their driving beams with a traverse attached to each of them with a grip for the rail head in the form of L-shaped hooks, rotated 90 ° along and across the rail head, each undercarriage is equipped with a hydraulic motor for its movement, a cable block with a traverse suspension system driven by a hydraulic cylinder, a traverse vibration damper and a pumping unit with a hydraulic system for I drive its hydraulic motors.

The mechanism for moving the undercarriage is the output shafts of the gearbox coaxially connected to the shafts of its two coaxial running wheels, the high-speed shaft of which is coaxially coupled to the shaft of the hydraulic motor.

The traction rope of the cable-block system of the traverse suspension is attached at one end to the traverse, thrown through a block mounted on the trolley, then through the block mounted on the rod rigidly attached to the trolley of the hydraulic cylinder, and its second end is mounted on the trolley.

The traverse vibration damper is made in the form of two pairs of levers, each pair of which is pivotally connected to each other, and also pivotally connected to the trolley and traverse with their ends, while the articulation is gapless with a significant contact area of the mating surfaces.

Each hydraulic motor of the hydraulic system of the trolley is connected with its four-way three-position valve with its strokes locked in a neutral position and interconnected by pressure and drain lines, and flow controllers controlled by the same valve are included in the hydraulic circuit.

The presence of two portals with traveling trolleys moving along their riding beams with a traverse on each of them with a grab for the rail head in the form of L-shaped hooks, rotated 90 ° along and across the rail head, allows for a minimum number of portals to perform various operations with rails on link assembly lines during their capture, movement and installation.

Equipping the undercarriage for its movement with a hydraulic motor allows you to adjust the speed of its movement, gently move it from its place and gently stop it for precise aiming of the traverse onto the rail or the place of its laying.

Equipping the undercarriage of the cable block with a hydraulic cylinder drive from the traverse suspension system allows you to smoothly lower the gripper onto the rail or rail to the place of its installation, while the traverse stroke exceeds the stroke of the drive hydraulic cylinder.

Equipping the undercarriage with a damper for lateral vibrations of the crosshead allows you to precisely guide the crosshead to the rail or the rail to its place in a shorter time.

Equipping each undercarriage with a pumping unit with a hydraulic system for driving its hydraulic motors (a hydraulic motor for moving it, a hydraulic cylinder for raising and lowering the crosshead, a hydraulic cylinder for driving the traverse capture) predetermines the use of electric motors of pumping units as the only energy source for driving all the mechanisms of the device for working with rails on a link assembly -assembly lines.

The mechanism for moving the undercarriage in the form of coaxially connected two coaxial shafts of its running wheels with low-speed shaft of the gearbox, the high-speed shaft of which is coaxially coupled with the shaft of the hydraulic motor, is structurally simple and allows more efficient control of the hydraulic motor when adjusting the speed of the moving carriage, since the speed of the hydraulic motor is controlled by high speed of rotation.

The cross-block suspension system of the traverse, when the rope is attached at one end to the traverse, is thrown through the block mounted on the trolley, then through the block mounted on the rod of the hydraulic cylinder rigidly attached to the trolley, and its second end is mounted on the trolley, it allows to transmit the traverse twice large stroke of the hydraulic cylinder, while increasing the reliability of the hydraulic cylinder by eliminating lateral forces on its stock.

The traverse vibration damper, made in the form of two pairs of levers, each pair of which is pivotally connected to each other, and also pivotally connected to the trolley and traverse with their ends, the hinge connection is made clearance-free with a significant contact area of the mating surfaces, which allows together with significant stiffness of the levers to provide damping of lateral vibrations of the traverse relative to the trolley when moving it from its place, stopping or other effects of transverse forces on the traverse. In addition, the lateral vibration damper levers fix the position of the traverse relative to the trolley and do not interfere with the separate operation of the device portals when raising and lowering their traverses, which allows the resolution of all kinds of situations that arise when working with rails on link assembly lines.

The implementation of the hydraulic system of the truck, where each of its hydraulic motors is connected to its four-way three-position valve with its strokes locked in a neutral position and interconnected by the pressure and drain lines, allows you to turn on the pump unit and its operation during periods when not one of the hydraulic motors is connected, minimum pressure. The inclusion in the hydraulic circuit of flow controllers, controlled by the same valve, allows you to adjust the response speed of a hydraulic motor.

A device for working with rails on assembly lines is comprised of two portals 1 enclosing a satellite trolley 2 or another device with a set of line link sleepers and a mobile warehouse 3 of rails or another device for rails. On the driving beam 4 of each portal, a running carriage 5 is mounted with the possibility of moving along it with a traverse 6 attached to it, equipped with a gripper 7 for the rail behind its head.

The undercarriage 5 for its movement along the driving beam 4 of the portal 1 is equipped with a mechanism, which consists of two coaxial running wheels 8 coaxially connected to the output shafts of the gearbox 9, the high-speed shaft of which is coaxially coupled to the hydraulic motor 10.

The traverse 6 to the undercarriage 5 is attached by means of a cable block system of its suspension. The traverse cable 11 of the traverse suspension is attached at its end 12 to the traverse 6, thrown through a block 13 mounted on the trolley, then through the block 14 mounted on the rod of the hydraulic cylinder 15 rigidly attached to the trolley, and its second end 16 is mounted on the trolley 5. Such a traverse suspension allows vertical movement of the traverse, twice the stroke of the hydraulic cylinder, and at the same time helps to unload the hydraulic cylinder from lateral forces on its rod.

The undercarriage 5 is equipped with a traverse vibration damper made in the form of two pairs of levers 17 and 18, each pair of which is connected to each other by a hinge 19. The levers 17 of each pair are connected to the trolley 5 by a hinge 20, and the levers 18 with a traverse 6 by a hinge 21. Each hinge the connection is gapless (Fig.7) with a significant contact area of the mating surfaces 22.

The grab 7 of the traverse 6 is made in the form of L-shaped hooks 23 fixed on it, the gripping legs 24 of which are rotatable 90 ° along and across the rail head by a hydraulic drive cylinder 25.

To drive the hydraulic motors of the device, a pumping unit 26 with a hydraulic system is mounted on the trolley 5. Each hydraulic motor of the hydraulic system - hydraulic motor 10, hydraulic cylinders 15 and 25 - is connected to its four-way three-position valve 27-29 with the hydraulic motor strokes locked in a neutral position and interconnected by pressure 30 and drain 31 highways. The hydraulic system includes flow controllers 32 and 33, controlled by the same control valve 34.

The device operates as follows.

On the link assembly line, the rails 35 are one at a time trapped by the traverse 6 on the rolling stock 3 of the rails, raised, moved to the satellite trolley 2 and laid on a set of sleepers of the assembled link.

On the linking line, the rails 35 are removed one by one from the sleepers of the disassembled link on the satellite trolley 2, moved to the rolling warehouse 3 of the rails and stacked on it.

The rails are gripped when the hydraulic cylinder 25 is turned on by its hydraulic distributor 28 by turning the gripping legs 24 from a position along the rail head under its head, which is not prevented by the adjacent rail of the rolling stock 3 rails (the pivoting lever 36 of the L-shaped hook 23 is located above the rail head). The release of the rail is carried out by turning the gripping tabs 24 from under the rail head along its head, which favors the laying of the rails close to each other on the movable warehouse 3 of the rails.

The captured rail is lifted by turning on the hydraulic cylinder 15 by its hydraulic distributor 27. When the hydraulic cylinder 15 is turned on by its hydraulic distributor 27 to lower the beam when it is planted on the rail or the rail to the place of its installation, the flow regulator 33 turns on the additional valve 34 to slow down the lowering speed of the beam for its soft landing on the rail or soft landing of the rail at the place of its laying.

The movement of the undercarriage 5 is carried out by turning on the hydraulic motor 10 with its hydraulic distributor 29. When the hydrodistributor 29 of the hydraulic motor 10 and the hydrodistributor 34 of the flow regulator 32 are simultaneously turned on, the movement speed of the undercarriage is set by adjusting the latter. To slow the speed of the approach of the traverse to the rail or the traverse with the rail to the place of its installation by the hydrodistributor 34, a flow regulator 33 is connected, which controls the speed of the approach. Adjusting the speed of the traverse to the rail approach or the traverse with the rail to the place of its laying with the presence of a damper of lateral vibrations of the traverse allows you to accurately direct the cross beam to the rail or rail to the place of its laying.

Joint and separate control of the running trolleys of each of the two portals with a significant vertical stroke of the traverse with the possibility of their separate lifting-lowering and moving along the portals allows you to work with a moving warehouse of rails in several of their tiers, grab the rails with their deviation from a straight and non-perpendicular position relative to the portals, maintain straightness and perpendicularity with respect to the portals of the rails during their laying, carry out the laying of rails by alternately lowering their ends c, that is, it allows the resolution of all kinds of situations that arise when working with rails on link assembly lines.

When the device is equipped with traverse position sensors relative to the rail, satellite cart, rail storage, it is possible to automate the processes of laying the rails when assembling the links or cleaning the rails when disassembling the links on the assembly-disassembling lines.
