The specific embodiment
Below contrast accompanying drawing, by the description to embodiment, the specific embodiment of the present utility model is described in further detail, to help those skilled in the art, inventive concept of the present utility model, technical scheme are had to more complete, accurate and deep understanding.
As shown in Figure 1 to Figure 3, the utility model provides a kind of simple and easy apparatus for correcting of oval ring, with a foursquare steel plate, makes base 8, perforate on four angles of base 8, can fix on the ground by foundation bolt, make the upper surface of base 8 become level.Be welded with a frame 7 on base 8.Frame 7 comprises two rectangular steel plates perpendicular to base 8, between two block plates, is welded with buttress brace.
Two flat idlers that are parallel to each other 1 are installed on base 8 by roller rack 9.Flat idler 1 is perpendicular to the steel plate in frame 7.Flat idler 1 is parallel to a diagonal of base 8, and with respect to this diagonal symmetry.The center of gravity of frame 7 drops on this diagonal, but departs from the center of base 8.Like this, the tilting moment opposite direction that the tilting moment that 7 pairs of bases of frame 8 produce and 6 pairs of bases of oval ring 8 produce, a part of tilting moment of cancelling out each other.When oval ring 6 is corrected, can prevent that oval ring 6 from, under Action of Gravity Field, causing excessive tilting moment to apparatus for correcting base 8.
Be welded with a gripper shoe 3 that is parallel to base 8 on frame 7, gripper shoe 3 is positioned at flat idler 1 top.Gripper shoe 3 has formed support with frame 7.Lower surface in gripper shoe 3 vertically is fixed with a backstay 2, as the detent mechanism to oval ring 6 location.A hydraulic jack 4 is installed on gripper shoe 3, as top bracing mechanism.Telescopic end above hydraulic jack 4 is installed with a shore 5.
Described backstay 2 is divided into the fixed bar and the screw-casings that are fixed on below gripper shoe 3 and is connected on the motion bar on fixed bar, motion bar and fixed bar threaded engagement.Shore 5 and backstay 2 are perpendicular to base 8.Two flat idlers 1 equate to the distance between backstay.The lower end of the upper end of shore 5 and backstay 2 all is fixed with curved plate, the one side ring contact-making surface of curved plate Contact Ellipse ring 6, and the ring contact-making surface matches with the inner surface of oval ring 6.Hydraulic jack 4 is selected as required, the length of shore 5 and backstay 2 and add that the jacking distance of hydraulic jack 4 is equivalent to the internal diameter of oval ring 6.
As shown in Figure 4, described flat idler 1 comprises roller carrier shaft 10, ball bearing 11, pivoted housing 12, spacer 13 and end cap 14.Roller carrier shaft 10 two ends are fixed on roller rack 9.Pivoted housing 12 is arranged on roller carrier shaft 10 by the ball bearing 11 at its two ends, pivoted housing 12 and described roller carrier shaft 10 matched in clearance.Be surrounded by a circle spacer 13 on the roller carrier shaft 10 between two ends ball bearing 11.All be stamped end cap 14 on two end faces of pivoted housing 12, the centre bore of end cap 14 and roller carrier shaft 10 couplings, covered ball bearing 11.End cap 14 all plays with spacer 13 effect of protecting ball bearing 11 and roller carrier shaft 10.This flat idler 1 can freely rotate like a cork, is convenient to the rotation adjustment of oval ring 6.
Before using this simple and easy apparatus for correcting to be proofreaied and correct, at first oval ring 6 is measured, calculated the radius deviation, mark and need the position of correcting; Carry out again deformation simulative, probably calculate ovality and correct needed power; Selecting accordingly the applicable hydraulic jack of jacking distance and calibrated force 4 to be arranged on gripper shoe 3.Shore vertically is fixed on the telescopic end of hydraulic jack 4, and the motion bar on backstay 2 is moved up.
During rectification, first by ovality, overproof oval ring 6 use suspender belts hang on flat idler 1, oval ring 6 is vertically stood on flat idler 1, and the center of oval ring 6 is dropped on the diagonal of base 8, and hydraulic jack 4, shore 5 and backstay 2 are arranged in oval ring 6.Rotate oval ring 6 and make to need the end of the position of rectification facing to shore 5 and backstay 2.Again motion bar is moved down afterwards to the inner surface that makes the ring contact-making surface touch oval ring 6, next utilize hydraulic jack 4 by shore 5 jack-up.
The rectification state be oval ring 6 from touching shore 5, receive the process of corrective force effect.Under the rectification state, the corrective force that hydraulic jack 4 applies acts on oval ring 6 by shore 5, gripper shoe 3, backstay 2, thereby the ovality of oval ring 6 is corrected.Now, hydraulic jack 4 forms a seal force system with oval ring 6 grades.Therefore when oval ring 6 is carried out to strength check, just do not need the hydraulic coupling of considering that hydraulic jack 4 applies.
After the ovality of a direction is corrected, hydraulic jack 4 is restored, above move the motion bar in backstay 2.Make again oval ring 6 roll under the effect of flat idler 1, until correct for the second time facing to the end of shore 5 and backstay 2 at the position that another direction need to be corrected.The general selection carried out the rectification of two to three directions to oval ring 6, can make oval ring 6 reach designing requirement.Whole apparatus structure is simple, compact, easy to make.Hydraulic jack 4 also can be used other top bracing mechanisms such as rack-jack or screw jack instead.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the concrete realization of the utility model is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasions without improvement, all in protection domain of the present utility model.
