Abstract
For an apparatus for correcting for heavy rail end head, be made up of a hydraulic cylinder, the thrust plate that is connected with hydraulic cylinder, it is to be relatively set with postive stop baffle with thrust plate; Between thrust plate and postive stop baffle, be provided with rectification plate one and rectification plate two, rectification plate one and rectification plate two are for being mounted opposite; Be respectively equipped with hook at rectification plate one and rectification plate two upper end, be respectively equipped with at thrust plate and postive stop baffle upper end and link up with the pocket for the punch head matched.The asymmetric shape that the utility model energy centering rail two ends are no more than 1 meter of length rail end has technique to cause is corrected and is met standard-required, and does not affect symmetry, the glacing flatness at other position, and structure is simple, easy to operate.
Description
Technical field
The utility model relates to a kind of apparatus for correcting, specifically belongs to a kind of apparatus for correcting for heavy rail end head, and it is specially adapted to heavy rail end head asymmetric is the rectification of the heavy rail end head being less than 1.7mm with standard deviation.
Background technology
High speed heavy rail is in the operation of rolling, and because fluctuating by pass collocation, section temperature, roll-force, roll rear roller transport and impact and the unequal factor impact of cooling velocity, rail can depart from the plane of symmetry, amesiality, namely produces asymmetry.In actual production, rail two ends be subject to above-mentioned factor to affect tail maximum, the asymmetrical type maximum probability namely produced at rail two ends.The gaugger used at present only can meet the requirement of the symmetry standard of rail interlude, then only can reduce asymmetric defect amplitude, but be difficult to standard-required for steel rail ends.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art existence, the asymmetric shape that providing a kind of energy centering rail two ends to be no more than 1 meter of length rail end has technique to cause is corrected and is met standard-required, and do not affect symmetry, the glacing flatness at other position, the apparatus for correcting for heavy rail end head that structure is simple, easy to operate.
Realize the technical measures of above-mentioned purpose:
For an apparatus for correcting for heavy rail end head, be made up of a hydraulic cylinder, the thrust plate that is connected with hydraulic cylinder, it is: be relatively set with postive stop baffle with thrust plate; Between thrust plate and postive stop baffle, be provided with rectification plate one and rectification plate two, rectification plate one and rectification plate two are for being mounted opposite; Be respectively equipped with hook at rectification plate one and rectification plate two upper end, be respectively equipped with at thrust plate and postive stop baffle upper end and link up with the pocket for the punch head matched.
It is characterized in that: rectification plate one is identical with rectification plate two structure and shape, and the shape that rectification plate one and rectification plate two are formed meets instructions for use; The hardness of rectification plate one and rectification plate two is the material being greater than rail mother metal highest hardness.
Feature of the present utility model: the asymmetric shape that energy centering rail two ends are no more than 1 meter of length rail end has technique to cause is corrected and meets standard-required, and does not affect symmetry, the glacing flatness at other position, and structure is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model and using state schematic diagram;
In figure: 1-hydraulic cylinder, 2-thrust plate, 3-postive stop baffle, 4-rectification plate one, 5-rectification plate two, 6-hook, 7-pocket for the punch head.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing:
For an apparatus for correcting for heavy rail end head, be made up of a hydraulic cylinder 1, the thrust plate 2 that is connected with hydraulic cylinder 1.It is fixedly installed postive stop baffle 3 relative with thrust plate by bolt or cast; Structure and the identical rectification plate 1 of shape and rectification plate 25 is provided with between thrust plate 2 with postive stop baffle 3, rectification plate 1 and rectification plate 25 are for being mounted opposite, the shape formed between rectification plate 1 and rectification plate 25 meets use standard-required, and the hardness of rectification plate 1 and rectification plate 25 is the material being greater than rail mother metal highest hardness; Adopt welding or overall processing to be connected with hook 6 respectively at rectification plate 1 and rectification plate 25 upper end, be processed with respectively at thrust plate 2 and postive stop baffle 3 upper end and link up with 6 pocket for the punch heads matched 7.
For the parts making rectification plate 1 and rectification plate 25 be connected with paper further connect firm, rectification plate 1 and rectification plate 25 can be connected with institute attaching parts by bolt.
Use principle
Rectification condition: heavy rail end head is asymmetric is be less than 1.7mm's with standard deviation.When being greater than 1.7mm, be then not suitable for adopting this device to correct.To avoid causing heavy rail waist to produce buckling phenomenon.
First by the asymmetric degree by checking model measurement heavy rail end head and incline direction; Inserted between the rectification plate 1 of this device and rectification plate 25 by asymmetric heavy rail end head, and the side that needs are corrected contacts with rectification plate 1, another side is put in rectification plate 25 side; Primer fluid cylinder pressure 1, makes hydraulic cylinder 1 by promoting thrust plate 2, to exert pressure rectification to needing the rail termination of rescuing.
This detailed description of the invention is only the best and exemplifies, the restricted enforcement not to technical solutions of the utility model.
