Description
Technical field
The invention belongs to butt welding of pipelines technical field, be specifically related to a kind of pneumatic mechanism that holds round.
Background technology
In the time of pipe laying, conventionally want to weld after two segment pipes docking, pipeline butt end ellipse is a difficult problem of welding, owing to being squeezed in pipeline transportation process, the reason such as collision, cause pipeline to produce certain ovality, make pipeline docking difficulty and poor welding quality.
At present, existing pipeline docking adopts the self-made tool docking such as card orchid and angle bar chock conventionally, use manpower control to reduce gap and unfitness of butt joint, but this method is difficult to ensure the circularity of pipeline, cause easily to make in when welding that weld seam width differs, the not first-class defect of weld bead height height, do not ensure welding quality; But also cause the waste of lot of materials.
Summary of the invention
The defect existing for above-mentioned prior art, the object of the present invention is to provide a kind of pneumatic mechanism that holds round, and it is simple, easy to operate that this holds round mechanism structure, can effectively improve the efficiency that pipeline holds round.
For achieving the above object, technical scheme of the present invention is: the pneumatic mechanism that holds round, comprise and hold round structure, wherein, described in hold round structure and comprise that a left side holds round plate and the right side holds round plate, both coordinate formation cylinder; Also be provided with double piston-rod cylinder, holder, guide post and guide holder, a left side holds round plate and the right side and holds round on plate and be equipped with holder, and two holders are along radially positioned opposite of cylinder, and two piston rods of described double piston-rod cylinder are connected with two holders respectively; Described guide post is located at the right side and is held round on plate inwall, and described guide holder is located at a left side and is held round on plate inwall, and is provided with the pilot hole that coordinates guiding with guide post; The flexible direction of piston rod of described double piston-rod cylinder is identical with the direction of guide post guiding.
While adopting technique scheme, the present invention is put into pipeline one end to be held round, a left side holds round plate and the right side and holds round plate outer wall and press close to inner-walls of duct, control double piston-rod cylinder and enter Compressed Gas, two piston rods of double piston-rod cylinder stretch out, and a left side holds round plate and the right side and holds round plate and be subject to rightabout thrust, so a left side holds round plate and the right side holds round plate counter motion, in this process, guide post and guide holder make a left side hold round plate and the right side to hold round plate radially softened.From the outside application of force of inwall of pipeline, pipeline is held round.The present invention adopts double piston-rod cylinder as power source, can fast pipeline be held round, and simple in structure, easy to operate, can effectively improve the efficiency that pipeline holds round.
Further, in described cylinder, be provided with two groups of guide posts and guide holder, and be positioned at the both sides of double piston-rod cylinder symmetry, be provided with the guide frame of two groups of symmetries, can ensure left hold round plate and rightly hold round the softened process of plate and can not be offset and misplace.
Further, a described left side holds round plate and the right side and holds round plate outer wall and be provided with rubber layer, and rubber layer can avoid pipeline to be held round stressed excessive.
Further, a described left side holds round plate and the right side and holds round plate and be provided with locating flange with one end, when locating flange can ensure pipeline to hold round, and the axiality of cylinder and pipeline.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the pneumatic structural representation that holds round mechanism for implementing example of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of pneumatic mechanism that holds round, comprises and holds round structure, wherein, hold round structure and comprise that a left side holds round plate 5 and the right side holds round plate 4, both coordinate formation cylinder; Also be provided with double piston-rod cylinder 1, holder 3, guide post 7 and guide holder 6, a left side holds round plate 5 and the right side and holds round and on plate 4, be equipped with holder 3, two holders 3 are along radially positioned opposite of cylinder, and two piston rods 2 of double piston-rod cylinder 1 are connected with two holders 3 respectively; In the present embodiment, guide post 7 is located at that the right side holds round plate 4 or a left side holds round on plate 5 inwalls, and guide holder 6 is located at that a left side holds round plate 5 or the right side holds round on plate 4 inwalls, and is provided with the pilot hole 61 that coordinates guiding with guide post 7; The flexible direction of piston rod 2 of double piston-rod cylinder 1 is identical with the direction that guide post 7 leads.
In the present embodiment, in cylinder, be provided with two groups of guide posts 7 and guide holder 6, and be positioned at the both sides of double piston-rod cylinder 1 symmetry, be provided with the guide frame of two groups of symmetries, can ensure left hold round plate 5 and rightly hold round the softened process of plate 4 and can not be offset and misplace.A left side holds round plate 5 and the right side and holds round plate 4 outer walls and be provided with rubber layer, and rubber layer can avoid pipeline to be held round stressed excessive.A left side holds round plate 5 and the right side and holds round plate 4 and be provided with locating flange with one end, when locating flange can ensure pipeline to hold round, and the axiality of cylinder and pipeline.
