The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and operation principle are described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of portable, all-dimensional continuous oil pipe straightening machine, comprise an air compressor 12, air compressor 12 links to each other with hydraulic booster device 10 by first oil pipe 11, hydraulic booster device 10 links to each other with oil cylinder 7 with the 3rd oil pipe 9 by second oil pipe 8, oil cylinder 7 and oil cylinder headstock 6 are by being threaded, the two sides of oil cylinder headstock 6 is connected with upper plate 14 and lower shoe 3 respectively, oil cylinder headstock 6 underrun bolts 23 connect lower shoe 3, position, hole in lower shoe 3 and upper plate 14 two ends symmetries is provided with two swinging oil pipe external arc supporting revolving shafts 17, fixing by two groups of bearing pins 19, in two bearing pins, 19 upper and lower side apertures, insert spring detent 18 fixed pin shafts 19, on the piston column cap 13 of oil cylinder 7, pressure head 2 is housed; Described pressure head 2 also is provided with 20, two blocks of supporting plates 20 of two blocks of supporting plates and is bell mouth shape, and supporting plate 20 is provided with scale 15, and scale 15 is used for determining the displacement of pressure head 2.
Described lower shoe 3 is installed two first universal wheels 21, at oil cylinder 7 rear portions one second universal wheel 22 is installed also, mainly is to move flexibly when being convenient to straightener work.
Described upper plate 14 and lower shoe 3 be provided with level and the symmetry hole 16, the symmetry hole 16 be used to install supporting revolving shaft 17, for the crooked coiled tubing 1 of alignment different-diameter designed.
With reference to Fig. 4, the radius of circle ratio is by the big 0.3-1 millimeter of alignment coiled tubing exradius in the R2 groove in the pressure head 2, and tubing diameter is big more, and the radius of circle gap is big relatively more in the R2 groove, when guaranteeing direct-connected continuous oil pipe pressurized, radius of circle closely contacts in elastic range in oil pipe cylindrical wall radius and the R2 groove; The interior radius of circle ratio of R1 groove is big 2 millimeters by alignment coiled tubing 1 radius in the pressure head 2, and the round hard rubber pad 24 that is provided with 3.5 millimeters thick in the R1 groove, prevents that coiled tubing 1 and pressure head 2 from rigidly connecting the excessive depression that causes of local pressure when touching; R3 groove radius size is bigger 3 millimeters than R2 groove radius size in the pressure head 2, and intersects according to bell mouth shape and R2 groove, prevents coiled tubing 1 when reversible deformation, is weighed wounded by pressure head 2 two-port.
With reference to Fig. 5, described spring detent 18 interludes and termination are respectively arranged with first projection, 25 and second projection 26, and convenient the insertion also can not guarantee after the insertion.
Supporting revolving shaft 17 has a circular arc groove face at least, and the interior radius of circle size R ratio of circular arc groove face is by the big 0.3-1 millimeter of alignment coiled tubing 1 exradius.With reference to Fig. 6, Fig. 6 is five kinds of view with five circular arc groove faces of supporting revolving shaft 17, Fig. 6 a is supporting revolving shaft 17 schematic diagrames, Fig. 6 b is the schematic diagram of supporting revolving shaft 17 rotation 72 when spending, Fig. 6 c is the schematic diagram of supporting revolving shaft 17 rotation 144 when spending, Fig. 6 d is the schematic diagram of supporting revolving shaft 17 rotation 216 when spending, Fig. 6 e is the schematic diagram of supporting revolving shaft 17 rotation 288 when spending, the size of R has nothing in common with each other among the figure, be when using for reality, according to the caliber of coiled tubing 1, select suitable circular arc groove face.
Operation principle of the present invention is: during operation, put into the present invention with needing the coiled tubing 1 of alignment, as shown in Figure 1, when hydraulic oil enters two-way cylinder 7 rear portions that are installed on the oil cylinder head 6, promote descent of piston, the pressure head 2 of dress is descending under piston promotes on the oil cylinder piston column cap 13, contact with the coiled tubing 1 of placing bending in the present invention gradually, and apply certain power, be placed on interior hard rubber pad 24 extrusions of R1 groove of pressure head 2, when making the hard rubber pad 24 that exceeds the R1 groove, pressure is forced into R2 groove diameter with pressure head 2 when identical, the metal part of R2 groove diameter begins to contact with the coiled tubing 1 of bending, hard rubber pad 24 has born very big compression in distortion at this moment, the compression of having disperseed crooked coiled tubing 1 middle part to concentrate simultaneously greatly, because the hardness of hard rubber pad 24 is lower than the hardness of crooked coiled tubing 1, therefore, the concentrated compression that crooked coiled tubing 1 middle part is subjected to is disperseed again; Can not cause the local dent at crooked coiled tubing 1 middle part.Along with pressure further raises, crooked coiled tubing 1 crooked curvature under the pushing of pressure head 2 is reducing gradually, the metal of R2 groove internal diameter part is also increasing with coiled tubing 1 contact area of bending, and the pressure that is pressed in unit are on the crooked coiled tubing 1 this moment increases and is few.In like manner, crooked coiled tubing 1 is by in the circular arc support slot that is pressed into two swinging coiled tubing external arc supporting revolving shafts 17 laying on lower shoe 3 and the symmetrical holes position, upper plate 14 two ends tightly, contacted by the curve of beginning and slowly forms the face contact.When the circular arc support slot of pressure head R2 groove inside radius and support rotating shaft 17 contacted with coiled tubing 1 formation complete face, crooked coiled tubing 1 was by straightening.In order to prevent that by temporary transient straightening coiled tubing 1 resilience, it is descending to need pressure head 2 to continue, make coiled tubing 1 produce certain reversible deformation, anti-deformation is definite from scale 15, then, and to two-way cylinder 7 front end oiling piston stroking upwards, regain pressure head 2, it is straight that coiled tubing 1 resilience becomes.After the alignment of this section oil pipe, aloft or the continuous mobile straightener in ground, and in 360 degree spaces, rotate straightener according to the tubing bending direction and come the alignment coiled tubing.
