Abstract

The conveyor for moving railway rails consists of a bed on which a double-row roller rail gripper with a drive and a chain for moving rails and a spring-screw assembly is placed in its guides, characterized in that the double-row roller rail grips are made in the form of double-row traction roller rollers, rigidly fixed to the bed, with the possibility of cyclic loading of the rail sole from the drive, the upper row is mounted on the bed with the possibility of vertical movement along its guides, on the bed There is a spring-screw assembly which presses the upper row of traction roller rollers to the rail head and through the sole of the rail to the lower row of traction roller rollers, the upper and lower traction roller rollers being driven through a chain clutch and gears mounted on the drive shafts of each row of traction roller rollers, interacting with each other in a zigzag chain connection.

FOR THE DECISION OF RAILWAY RAILS.

The utility model relates to mechanical engineering and can be used for transportation of long products, such as railway rails in technological workshops.

Known self-propelled devices for moving railway tracks, containing a beam connected to the carrier (tractor), on which roller rails with SILOVBM drive are installed, for example, 1,2,3 hydraulic cylinders.

The disadvantage of such conveyors is the bulkiness, the complexity of the design, the inability to move long products, as well as the capture of the rail with roller grips for its neck, which creates mechanical stresses in the neck of the rail.

Known two-speed traction conveyor with electric drive for moving the rails of the rail mill of the model MS 783-000-00 designed for gouging on the rails of types P50-P75 4.

CONVEYOR

Portals, worm gearboxes of the main drive, roller blocks, pressure devices and supporting rollers have been updated. Worm gearboxes are mounted on the platens of the side wall of the bed and are interconnected by elastic couplings.

The output shaft of each worm gearbox is connected via bevel gears to the drive shaft of the block of profile rollers that capture and move the rails.

Profile rollers are mounted on the output shafts of bevel gears that make up the roller block assembly.

One of the bevel gears is fixed rigidly, the second has the ability to move with a special clamp.

There are two clamps - one for pressing the rollers against the neck of the rail, and the second for creating the effort of pressing the rollers.

The disadvantage of this traction conveyor along the rails is the design complexity, the presence of a large number of angular gears, worm and bevel gears, the inability to move long rail lashes. The technical result to which

directed creation of a utility model, is to ensure the movement of long rail lashes with reversibility in movement and simplification of design.

The stated technical goal and its result is achieved by the fact that the design of the conveyor for moving railway rails consists of a drive connected to two-row roller grippers, which are traction roller rollers installed in the frame guides with spring-screw assemblies.

The lower row of traction roller rollers is rigidly mounted on the bed with the possibility of rotation from the drive and cyclic loading from the spring-screw unit of the upper row to the rail base, and the upper row is mounted on the bed with the possibility of vertical movement along its guides, pressing the rail head through the screw base by screw assembly to the lower row of traction roller rollers, and the upper and lower roller rollers are driven synchronously by a chain clutch and gears mounted on the drive shafts of each row Jagow roller rolls interacting with each other in a zigzag chain

communication.

An analysis of the prior art by the applicant, including a search by patent and scientific and technical sources of information and identifying sources containing information about analogues of the claimed scientific model, made it possible to establish that the applicant did not find an analogue characterized by features identical (identical) to all essential features of the claimed utility model .

The definition from the list of analogues of the prototype made it possible to identify the set of significant relative to the perceived technical result of the positive signs in the claimed utility model set forth in the claims.

In the accompanying drawings, FIG. 1 is a general view of the traction conveyor, FIG. 2 is a top view of the conveyor; FIG. 3 is a section through the conveyor along AA; FIG. 4 is a sectional view of the conveyor along BB, FIG. 5 - kinematic diagram of the conveyor.

The conveyor for moving rail lashes consists of a bed 1 on which gear wheels 2 are mounted; stars 3, 4; clamping screws 5; chain b; traction roller rollers 7; clutch chain 8;

springs 9; axle box bearing units of traction roller rollers 10; rack 11 and the main drive for moving the rails consisting of a gear 12, an electric motor 13, a belt drive 14.

The mounting mechanism of the electric motor of the main drive allows you to adjust the tension of the drive transmission belts of the belt 14 as they wear.

The conveyor for moving railway rails works as follows: the plane of the sole of the conveyor rail lane runs along a tangent line to the rims of the lower row of roller traction rollers 7 of the conveyor.

When refueling the lash in the conveyor, the clamping screws 5 and springs 9 are in a loose free state.

The rail lash is tucked between the lower and upper row of traction roller rollers 7. By tightening the screws 5, the springs 9 are compressed, which transfer the compressive force to the axlebox bearings 10 of the traction roller rollers 1, creating a pressing force of the upper and lower row of traction roller rollers 7 with the base and head rail lash.

rollers through a chain clutch 8, gears 2 and chains b form a zigzag chain connection, creating synchronous traction force to the lower and upper row of traction roller rollers 1, moving rail lashes.

The use of the proposed conveyor allows loading and unloading operations when forming rail couplers and rail lash drives, as well as when feeding rails along live conveyor lines for lashing, processing and flaw detection.

The conveyor allows you to move rail lashes up to 1500 m long and move in curved sections of technological production lines with a curvature of up to 100 m. Authors: Applicant :. Direct travel {m 11ShT rSh 11 S.V. Luzhin Yu. A. Gaponenko S.V. Luzhin
