The method has the advantage of solving the problem that the yield of the steel pipe is influenced by the out-of-roundness standard of the steel pipe in the processing and manufacturing process of the steel pipe for the long pipeline.
Description
The technical field is as follows:
the utility model relates to a carry out prosthetic device to industry long distance pipeline with welding steel pipe end out-of-roundness.
Background art:
the non-roundness of the steel pipe refers to the percentage of the difference between the maximum pipe diameter and the minimum pipe diameter on the cross section of the steel pipe in the specified outer diameter of the steel pipe, reflects the roundness condition of steel pipe processing, and has the calculation formula as follows:
the non-roundness of the steel pipe is not required to be equal to (the maximum pipe diameter-the minimum pipe diameter)/the specified outer diameter is 100 percent;
in the manufacturing process of the industrial long-distance steel pipe, the coil forming process of the steel pipe is easy to cause out-of-roundness standard of the steel pipe, namely, two ends of the steel pipe are out-of-roundness. The steel pipes with non-circular pipe ends can not be normally welded on the pipeline construction site, which directly influences the construction quality and efficiency of the long-distance pipeline. Therefore, strict requirements are made on the out-of-roundness of the steel pipe in the manufacturing standard of the steel pipe, and the steel pipe with the out-of-roundness exceeding the standard in the production of a pipe manufacturing enterprise can only be degraded or scrapped, which greatly affects the yield of the steel pipe manufacturing.
In order to solve the problem that the out-of-roundness of the steel pipe exceeds the standard, the problem that the out-of-roundness of the steel pipe cannot be completely solved only by adjusting the steel pipe manufacturing process is difficult to solve, so that a device capable of repairing the out-of-roundness of the steel pipe in the steel pipe machining process is urgently required to be designed and manufactured.
The invention content is as follows:
the utility model aims to solve the technical problem that a steel pipe out-of-roundness prosthetic devices that improves steel pipe lumber recovery is repaired to the out-of-roundness at steel pipe both ends that can be quick, convenient is provided.
The above object is achieved by: the lower surface of the lower arc seat is arc-shaped, and the radian of the lower arc seat is consistent with the standard radian of the inner wall of the repaired steel pipe; the upper surface of the upper arc seat is also arc-shaped, and the radian of the upper arc seat is consistent with the standard radian of the inner wall of the repaired steel pipe.
A connecting sleeve is fixed at the bottom of the upper arc-shaped seat, and the upper end of the guide rod extends into the connecting sleeve;
the bottom of the upper arc-shaped seat on two sides of the connecting sleeve is respectively connected with an upper guide plate through a bolt, the top of the lower arc-shaped seat is respectively fixed with two lower guide plates through bolts, the lower parts of the two upper guide plates are provided with long bolt mounting holes, the upper parts of the two lower guide plates are provided with long bolt mounting holes, and the upper guide plate and the lower guide plate which are positioned on the same side are connected together through bolts in the long bolt mounting holes.
The hydraulic jack is arranged on the upper surface of the lower arc-shaped seat and is connected with the lower end of the guide rod.
And reinforcing ribs are fixed on the upper arc-shaped seat and the lower arc-shaped seat.
The utility model has the advantages that: the method successfully solves the problem that the yield of the steel pipe is influenced by the out-of-roundness of the steel pipe in the processing and manufacturing process of the steel pipe for the long-distance pipeline, helps steel pipe manufacturing enterprises to improve the product quality, saves the processing cost and creates considerable economic benefit. The device has more obvious effect on the steel pipe for the low-steel-grade water delivery pipeline, and the repair rate of the steel pipe with out-of-roundness exceeding reaches more than 98 percent.
Description of the drawings:
fig. 1 is a schematic front view of the present invention;
FIG. 2 is a schematic view of the upper arc seat of the present invention;
FIG. 3 is a schematic view of the lower arc seat of the present invention;
fig. 4 is a schematic side view of the lower and middle guide plates of the present invention.
The specific implementation mode is as follows:
the present invention will be further described with reference to FIGS. 1-4;
the lower surface of the lower arc seat is arc-shaped, and the radian of the lower arc seat is consistent with the standard radian of the inner wall of a repaired steel pipe; the upper surface of the upper arc seat is also arc-shaped, and the radian of the upper arc seat is consistent with the standard radian of the inner wall of the repaired steel pipe.
The connecting sleeve 3 is fixed at the bottom of the upper arc-shaped seat, and the upper end of the guide rod 4 extends into the connecting sleeve;
the bottom of the upper arc-shaped seat on two sides of the connecting sleeve is respectively connected with an upper guide plate 5 through a bolt, the top of the lower arc-shaped seat is respectively fixed with two lower guide plates 6 through bolts, the lower parts of the two upper guide plates are provided with long bolt mounting holes 7, the upper parts of the two lower guide plates are provided with long bolt mounting holes, and the upper guide plate and the lower guide plate which are positioned on the same side are connected together through bolts 8 in the long bolt mounting holes. The upper guide plate and the lower guide plate can play a role in guiding and supporting in work, the problem that the device is broken due to too large acting force of the power mechanism is prevented, and the safety and the stability of the device in operation are greatly improved.
