Description
Technical field
The utility model belongs to the erecting tools technical field, particularly a kind of used specialist tools of pipe flange fast assembling-disassembling that is used for.
Background technology
In the pipeline maintenance process, the dismounting flange is necessary operating process.But because the pipeline major part is embedded in undergroundly, all do not dismantle for a long time, that the nut rust is died in an accident or political incident is quick detachable, the large scale flange is the phenomenon of often running into because of adhesion for a long time is difficult to separate, in addition, in installation process, the large scale flange is generally bulky, and weight is bigger.General strong sled of external force or the oxygen welding cutting means of adopting of nut dismounting at present; Adopt axe filers tool for the flange that is difficult to separate more; And for the installation of flange, the way of lifting is manually supported and shoulders in many employings, and only labour intensity is big, and safety inadequately.Particularly to the pipeline of carrying hazardous goods such as inflammables and explosives is arranged, these means are all forbidden to use.Therefore, a kind of dismounting of pipeline safely and effectively of design is according to just becoming the task of top priority.
Summary of the invention
The utility model purpose provides a kind of sheathing tool of pipe flange fast assembling-disassembling, to be particularly suitable for the dismounting safely and fast to the pipeline of carrying hazardous goods such as inflammables and explosives.
Specifically, the utility model comprises nut cut-open device, flange separator, three instruments of flange docking adapter.
The nut cut-open device of a kind of pipe flange fast assembling-disassembling wherein, it is to have one to be enclosed within the collar nut framework (1-6) of locating on the desire dismounting nut, the piston rod (1-2) that is loaded on oil cylinder (1-1) end is arranged in the passage of nut framework (1-6) can move left and right, is fixed with in the end of piston rod (1-2) and dissects cutter (1-4).
Fairlead (1-3) to piston rod (1-2) guide-localization also is housed on nut framework (1-6).
The flange separator of a kind of pipe flange fast assembling-disassembling wherein, it has an oil cylinder (2-4), taper is installed in oil cylinder (2-4) end separates head (2-2), the alignment pin (2-1) of the flange that will separate or pipeline location is positioned at and separates first side, and cylinder cap (2-3) is connected as one the support body of oil cylinder and alignment pin.
The flange docking adapter of a kind of pipe flange fast assembling-disassembling wherein, it comprises oil cylinder (3-6), the knock-off joint (3-11) of adjusting the flange position is housed in oil cylinder (3-6) end, at oil cylinder (3-6) middle part crossbeam (3-3) is housed, angle-adjusting mechanism is equipped with in the other end of crossbeam (3-3), the middle part of crossbeam (3-3) be equipped with vertical beam (3-8) and this vertical beam can be on crossbeam move left and right, vertical beam (3-8) other end is equipped with the screw cover (3-10) that can be set in the flange hole, and this screw cover is by alignment pin (3-9) fixed position.
Described angle-adjusting mechanism comprises leading screw (3-1), adjusts nut (3-2) and leading screw sleeve (3-7), and leading screw is contained in the leading screw sleeve, adjusts nut and is contained in outside the leading screw sleeve, and leading screw one end withstands in the sleeve that is contained in crossbeam (3-3) end.
The location screws handle (3-5) between also being equipped with vertical beam and crossbeam (3-3) on the vertical beam (3-8).
The beneficial effects of the utility model:
Described nut cut-open device is enclosed within an annular frame on the nut that will remove, utilizes the thrust of the hydraulic cylinder generation of framework one side to drive a triangular blade, cuts the nut of corrosion in the annular frame open.This product can dissect the nut scope of different sizes, different angles.This product weight is light, and strength is big, uses easy to carryly, and stable working is reliable, can not produce potential safety hazards such as spark.
In the maintenance of pipeline, because the flange connect hours is longer, flange often becomes rusty extremely on tank body, or pipeline adpting flange rust extremely together, is difficult to separate by manpower, and the maintenance personal uses the hatchet and chisel instrument to separate usually, and genus is seriously operated against regulations.Flange separator in the utility model with the bolt hole of flange location, inserts the taper cutting edge of separator in the middle of two flanges that will separate the flange separation that the thrust of utilizing oil cylinder to produce will become rusty dead.
In the installation of heavy caliber, the various pipelines of large span, because the influence of factors such as the weight of pipeline and welding deformation, the adpting flange of pipeline misaligns, two pipe flanges are very difficult with simple hand tools centering, usually installation personnel adopts method operations such as brick wood support, and installation effectiveness is low.Flange docking adapter in the utility model, with a flange hole to be connected and pipeline location, the piston rod of docking adapter front end is oppressed another higher flange, makes two flange centerings,
In a word, the utility model has fundamentally solved the practical problem in the pipeline installation, maintenance, has eliminated potential safety hazard, has improved operating efficiency, has alleviated pipeline maintainer's labour intensity.
