Detailed Description
The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.
As shown in fig. 1-3, the utility model provides an improve big pipe diameter steel pipe accuracy device that is geared to needs of job, include:
the connecting plates 6 are arranged at intervals along the circumferential direction of the end part close to the pipeline 1, and first through holes are formed in the connecting plates 6; the anchor ears 5 are arc-shaped, the anchor ears 5 are arranged between two adjacent connecting plates 6 on the pipeline 1, and opposite ends of the two adjacent anchor ears 5 are fixed on the same connecting plate 6 through bolts 4; and two ends of each hydraulic cylinder 2 are respectively fixed on the bolts 4 which are oppositely arranged on the two adjacent pipelines 1, and the hydraulic cylinders 2 are driven by a hydraulic pump. The positioning wedges 3 are arranged at intervals along the circumferential direction of two adjacent pipelines 1 and are only fixed on the anchor ear 5 on one of the pipelines 1, and the free ends of the positioning wedges 3 abut against the two adjacent pipelines 1.
In the technical scheme, firstly, the connecting plates 6 are respectively welded with the pipelines 1; secondly, fixing the positioning wedge blocks 3 on the anchor ears 5, wherein the positioning wedge blocks 3 on the circumferential direction of the pipeline 1 can fix the pipeline 1 along the radial direction of the butt-welded pipeline 1; subsequently, the anchor 5, the connecting plate 6 and the hydraulic cylinder 2 are connected by the bolt 4. Because the connecting plate 6 is connected with the pipeline 1, when the hoop 5 is connected with the connecting plate 6, the hydraulic cylinder 2 connected with the hoop 5 is also connected with the pipeline 1, so that the butt welding device is fixed on the pipeline 1; then, the hydraulic cylinder 2 is driven by the hydraulic pump to move the pipe 1. Because the connecting plate 6 is arranged on the pipeline 1, when the hydraulic pump drives the hydraulic cylinder 2 to move the butt-welded pipeline 1 along the axial direction of the pipeline 1, the pipeline 1 is driven to approach along the axial direction, the width of a welded junction is adjusted, and therefore the welded joint of the pipeline 1 is welded; and finally, the device is disassembled in the sequence that the bolt 4 for connecting the hydraulic cylinder 2, the hoop 5 and the connecting plate 6 is firstly disassembled, and then the hoop 5 is taken down from the pipeline.
In another technical scheme, the width of the hoop 5 is 80mm, and the thickness of the hoop is 5 mm. The anchor ear 5 has a certain width and thickness, so that the bolt 4 can connect the hydraulic cylinder 2, the connecting plate 6 and the anchor ear 5, and the hydraulic cylinder 2, the connecting plate 6 and the anchor ear 5 are fixed on the pipeline 1.
In another technical scheme, the number of the connecting plates 6 at the port to be connected of the pipeline 1 is 4; the number of the hoops 5 at the positions of the to-be-connected ports of the pipeline 1 is 4. The number of the hoops 5 and the number of the connecting plates 6 on each side of the pipeline 1 are the same because the connecting plates 6 are arranged at the lug butt joint of the adjacent hoops 5. Due to the structural design, when the hydraulic pump drives the hydraulic cylinder 2 to move, the stress of the pipeline 1 is uniform, and the moving distance of the pipeline 1 along the axial direction is the same as much as possible.
In another technical scheme, lugs are arranged at two ends of the hoop 5, threaded holes are formed in the lugs, and the bolts 4 penetrate through the threaded holes. The bolts 4 penetrate through lugs at two ends of the hoop 5 to fix the hoop 5 on the pipeline 1. In addition, the bolt 4 can also be connected with the connecting plate 6, the hydraulic cylinder 2 and the hoop 5, and the connecting plate 6 is connected with the pipeline 1, so when the hydraulic pump drives the hydraulic cylinder 2 to move axially along the pipeline 1, the pipeline 1 can be driven to move axially.
In another technical solution, the method further comprises: when the diameter of the pipeline 1 is 1000mm or less, the number of the positioning wedge blocks 3 is 4; when the diameter of the pipeline 1 is larger than 1000mm, the number of the positioning wedge blocks 3 is 6. The number of locating wedges 3 increases as the diameter of the pipe 1 increases. As the diameter of the pipe 1 increases, more positioning wedges 3 are required to improve the stability of the pipe 1 in the radial direction.
In another technical scheme, still include, the location voussoir 3 is the cuboid, the length of location voussoir 3 is 40mm, and wide is 40mm, and high is 250 mm. The same positioning wedge 3 having a certain length may be connected to one end of one pipe 1 and the other end of the same positioning wedge may be connected to the other pipe 1, thereby improving the stability of fixing in the radial direction of the pipes 1.
In another technical scheme, the method further comprises the step that the positioning wedge blocks 3 are uniformly and symmetrically arranged on the hoops 5 of the to-be-connected ports of the pipeline 1. Because the positioning wedges 3 are evenly and symmetrically distributed on the anchor ear 5, when the anchor ear 5 is connected to the pipeline 1, the distribution of the positioning wedges 3 on the pipeline 1 is also evenly and symmetrically distributed. Therefore, when the positioning wedge 3 fixes the pipeline 1 along the radial direction of the pipeline 1, the stress of the pipeline 1 is also uniform and symmetrical, thereby improving the stability of the pipeline 1 along the radial direction.
