Abstract
The utility model discloses a hot steel rail straightener belongs to metal material aligning technical field. The device consists of guide rollers, a machine base and a straightening system, and is structurally characterized in that the straightening system at least comprises three pairs of main (driven) driving wheels and a channel of a steel rail is formed by a roller gap between each pair of driving wheels. Each straightening wheel is provided with an independent roll gap adjusting device, and the size of the roll gap can be adjusted according to the section size of the steel rail. The device has simple structure and applicability, can effectively prevent the steel rail from being crushed or the change of the geometric dimension and the shape in the straightening process, and is particularly suitable for straightening the steel rail before online heat treatment.
Description
The utility model belongs to metal material straightening technology field, particularly a kind of hot steel rail straightening device.
In the prior art, rail all is at room temperature to align.Employed multi-roll straightening machine must have certain drafts when straightening of kinked rail, make the rail alternating bending until being aligned.
The online heat treatment technics of rail of exploitation need be carried out straightening processing to the rail that is in red heat state (〉=700 ℃) at present.If adopt straightener of the prior art, be used for the aligning of this red heat state rail, obviously there are problems:
1. equipment is huge, complex structure, and investment is big;
2. because of having certain drafts, make the rail alternating bending, easily weigh rail wounded, and its geometry, size are changed.
The purpose of this utility model provides a kind of device that is in red heat state rail that is used to align, so that rail is carried out online heat treatment.
The purpose of this utility model is achieved through the following technical solutions:
Hot steel rail straightening device comprises guide reel, straightening system and support, and guide reel and straightening system are installed on the support, and guide reel is positioned at before the straightening system, it is characterized in that:
(1) straightening system comprises a pair of driving wheel and two pairs of followers, and driving wheel, follower are distributed in the both sides of support by certain distance, between the driving wheel and the roll gap between the every pair of follower form the passage of rail:
(2) driving wheel, follower have independently roll-separating mechanism separately, and the roll-separating mechanism of being told comprises chute, balladeur train, bearing, axle, screw mandrel; Balladeur train is embedded in the chute by the both sides slideway; Screw mandrel one end connects with support, and the other end connects with balladeur train, and each balladeur train connects with driving wheel and follower respectively by bearing mounted thereto and axle.
(3) roll-separating mechanism of the driving wheel of being told also comprises the elasticity squeezer, and the elasticity squeezer is made up of spring, spring base, pressing plate and nut; Spring base is positioned on the support, and spring is housed in it; Pressing plate is installed in the screw mandrel middle part by its internal thread, and screw mandrel passes spring and spring base connects with nut.
Further be that the spring in the roll-separating mechanism of the driving wheel of appeal is butterfly spring preferably.
Further be in the above-mentioned hot steel rail straightening device, on the outer rim of each driving wheel and follower, Scaler to be installed.
Because this device does not have drafts, rail is not directly imposed the external force of alternating bending, compared with prior art, has following obvious advantage:
1. simple in structure, reduced investment;
2. effectively prevented the geometry, the change in size that weigh rail wounded in the aligning process or cause rail.
Accompanying drawing 1 is the vertical view of the utility model embodiment;
Accompanying drawing 2 is for being the A-A cutaway view of the utility model embodiment;
Accompanying drawing 3 is the B-B cutaway view of the utility model embodiment;
Below, in conjunction with the accompanying drawings the utility model is further described:
Embodiment:
Hot steel rail straightening device, comprise guide reel 1, support 2, chute 3, driving wheel 4, follower 5, Scaler 6, balladeur train 7, bearing 8, axle 9, screw mandrel 10, spring 11, spring base 12, pressing plate 13, nut 14, guide reel 1 is installed on the support 2, and be positioned at the straightening system front end, be used for rail is imported straightening system; A pair of driving wheel 4 and two pairs of followers 5 are installed on the balladeur train 7 by axle 9, bearing 8, and balladeur train 7 can be moved on support 2 by chute 3 guiding, and are adjusted, located by the screw mandrel 10 that connects with support 2; Wherein on the adjustment screw mandrel 10 of driving wheel 4 pressing plate 13 is housed, and links to each other with support 2 by spring 11, nut 14, spring base 12; Adjust nut 14, determine the relative position of driving wheel 4 on support 2, adjust pressing plate 13, determine the pressure of spring 11; What spring 11 adopted is butterfly spring; The outside at each driving wheel 4 and follower 5 is equipped with Scaler 6, and each takes turns the iron scale of going up adhesive tape in the aligning process to wipe off, guarantees not damage the rail surface.
Handle different rail, the aligning wheel and the Scaler of the corresponding pass that changes the outfit; Adjust driving wheel 4, make it produce constant compression force the rail web of the rail; Adjust follower 5, make its roll gap be slightly larger than web of the rail thickness.During aligning, the rail 16 of red heat guides by guide reel 1, is nipped and pushes away it by driving wheel 4 and pass through straightening system.The center line of the rail passage that the roll gap of taking turns because of three pairs of alignings forms is adjusted to a straight line, only allows straight rail by straightening system, and the crooked position of rail is just automatically by the corresponding wheel straightening of aligning.
