Abstract
The utility model discloses a steel pipe roundness correction device of a bridge. The steel pipe roundness correction device comprises an annular steel board, reinforcing steel boards, screw rods and nuts. A through hole is formed in the middle of the annular steel board, and the upper surface of the annular steel board is provided the nuts which are distributed with equal distances. The two sides of the nuts are respectively provided with one reinforcing steel board, and the outer surfaces of the two sides of the nuts are welded and fixed with the inner surfaces of the reinforcing steel boards. The nuts and the reinforcing steel boards are perpendicular to the annular steel board and welded to the upper surface of the steel board. The threaded sections of the screw rods are fixed with the nuts in a matched mode, and the head portions of the screw rods face the through hole of the annular steel board. When the steel pipe roundness correction device is used, the roundness correction device is placed into the end portion of an out-of-round steel pipe, the screw rods are screwed so that the screw rods can be in close contact with the inner wall of the steel pipe and the annular steel board can be perpendicular to the steel pipe. All the screw rods are screwed so that the radial diameters of the screw rods can be identical. The steel pipe roundness correction device of the bridge is simple in structure, convenient to use, capable of effectively correcting steel pipes with different inner diameters by adjusting the screw rods and capable of solving the roundness correction problem of the steel pipes on a bridge construction field.
Description
Technical field
The utility model relates to a kind of adjustment equipment, especially a kind of bridge steel plate pipe circle correcting device.
Background technology
The basis of the temporary facility steel construction that bridge construction is used is spiral steel pipe, because steel pipe can reuse, the setting of steel pipe, use, all can make steel pipe produce distortion in dismounting and transportation, the docking of its next time is used and impacted, and existing steel pipe circle correcting device exists the shortcomings such as use is inconvenient, calibration result is not good, cause steel pipe reusing poor.
Summary of the invention
The purpose of this utility model is to provide a kind of bridge steel plate pipe circle correcting device.
What the utility model solved is that the circle correcting device existing in prior art is used inconvenience, the not good problem of calibration result.
The technical scheme that the utility model technical solution problem adopts is: it comprises doughnut-shaped steel plate, strengthens steel plate, screw rod and nut, in the middle of described doughnut-shaped steel plate, be provided with through hole, the upper surface of described doughnut-shaped steel plate is provided with the nut of equidistant branch, nut both sides are respectively equipped with a reinforcement steel plate, and nut two side external surfaces are welded and fixed with reinforcement inner surface of steel plate, described nut and strengthen steel plate all perpendicular to doughnut-shaped steel plate and be welded thereon on surface, described screw flight section and nut are fixed, and the head of described screw rod is towards doughnut-shaped steel plate through hole.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, by adjusting screw(rod), can realize the steel pipe school circle to different tube diameters.
