Description
Technical field
The present invention relates to provision for disengagement field, in particular it relates to a kind of device dismantling multisection type oil drill rocker.
Background technology
In the recovery process of oil, drilling rod is a kind of requisite instrument, owing to oil well is the deepest, so the drilling rod of exploitation oil generally uses the drilling rod of multisection type, the joint drilling rod damaged is changed when a certain section of drill pipe wear, when splitting the drilling rod damaged, after needing first to be fixed by the two ends drilling rod damaging drilling rod, then with provision for disengagement, the drilling rod damaged is split.Existing provision for disengagement the most all uses the cylinder clamping drilling rod of hollow, and fluid pressure type driving means drives drilling rod to rotate in the axial direction, so that drilling rod splits.Existing provision for disengagement needs to insert drilling rod the cylinder clamping section of hollow when clamping drilling rod, and the drilling rod longer for length operates relatively difficult when clamping.
Summary of the invention
The technical problem to be solved is to provide a kind of device dismantling multisection type oil drill rocker, to overcome clamping section the most easy-operating problem when inserting drilling rod of existing provision for disengagement.
The present invention solves the problems referred to above and be the technical scheme is that the device of dismounting multisection type oil drill rocker, including hydraulic base, hydraulic cylinder, holding ring, fixing device, holding ring includes the snap ring of two symmetrically arranged semicircle shapes, snap ring is provided with beginning and blind end, the blind end of the snap ring of two symmetries is connected by loose-leaf, the beginning of two snap rings is provided with connecting plate, the tapped through hole coordinated with screw rod, nut it is provided with on connecting plate, the inwall of snap ring is provided with flank, and the outer wall of snap ring is evenly arranged with multiple fixed block.nullOwing to snap ring is provided with the beginning，When clamping drilling rod，First the beginning of snap ring is opened，Drilling rod was inserted in two snap rings by the beginning，By the beginning closing in snap ring，Tighten with nut again after tapped through hole with screw rod，Multiple screw rods and nut with the use of drilling rod well being fixed，Inwall at snap ring is provided with flank，Flank has bigger frictional force，Hydraulic cylinder promotes snap ring rotation can accomplish easily for those skilled in the art，Snap ring rotates and drives drilling rod to rotate，Thus drilling rod is split，Flank makes snap ring inwall have resistance with drilling-rod external wall when rotating，Avoid drilling rod to skid at snap ring inwall，And，Snap ring thickness in the axial direction it is set smaller than after fixed block，The present invention by being set to the semicircle snap ring of two symmetries by holding ring，The blind end loose-leaf of two snap rings connects，Beginning is connected with screw fit by screw rod，The beginning making snap ring can open and close freely，It is easy to the insertion of drilling rod，Overcome clamping section the most easy-operating problem when inserting drilling rod of existing provision for disengagement.
Further, the blind end of snap ring offers through hole, is provided with rotating shaft in through hole, and the two ends of rotating shaft are connected on the bearing of fixing device.Such fixing device does not interferes with hydraulic cylinder and drives the rotation of snap ring.
Further, rotating shaft is arranged on the securing means by screw.Screw is detachable connected mode, it is simple to the replacing of snap ring, when snap ring changed by needs, directly fixing device and rotating shaft is split, and the replacing making snap ring is more convenient.
Further, connecting plate is welded on snap ring outer wall.The mode of welding is the most firm, it is to avoid the phenomenon occurring connecting plate to come off during two snap rings Guan Bis, improves stability during two snap rings Guan Bis.
Further, the thickness of connecting plate is set to 20mm-30mm.This thickness guarantees to offer thereon stability during tapped through hole, more wastes time and energy when avoiding the waste of the excessive material caused of connecting plate thickness simultaneously and offer through hole.
To sum up, the invention has the beneficial effects as follows:
1, the present invention by being set to the semicircle snap ring of two symmetries by holding ring, the blind end loose-leaf of two snap rings connects, beginning is connected with screw fit by screw rod, the beginning making snap ring can open and close freely, it is easy to the insertion of drilling rod, overcomes clamping section the most easy-operating problem when inserting drilling rod of existing provision for disengagement.
2, the present invention is by by connection detachable for rotating shaft on the securing means, improves the convenience that snap ring is changed.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is made detailed description further, but embodiments of the present invention are not limited to this.
Embodiment 1:
Such as Fig. 1, shown in Fig. 2, the provision for disengagement of bar, including hydraulic base 1, hydraulic cylinder 2, holding ring, fixing device 3, holding ring includes the snap ring 5 of two symmetrically arranged semicircle shapes, snap ring 5 is provided with beginning 53 and blind end 54, the blind end 54 of the snap ring 5 of two symmetries is connected by loose-leaf 4, the beginning 53 of two snap rings 5 is provided with connecting plate 52, connecting plate 52 is welded on snap ring 5 outer wall, the thickness of connecting plate 52 is set to 20mm-30mm, it is provided with on connecting plate 52 and screw rod 7, the tapped through hole 55 that nut 8 coordinates, the inwall of snap ring 5 is provided with flank, the outer wall of snap ring 5 is evenly arranged with multiple fixed block 51.
The insertion of drilling rod is easy in the setting of symmetrical expression snap ring 5, and snap ring 5 can well be fixed by fixing device 3, and hydraulic cylinder 2 promotes snap ring 5 to rotate in the axial direction.
Embodiment 2:
The present embodiment is on embodiment 1 basis, and as shown in Figure 1 and Figure 2, the blind end 54 of snap ring 5 offers through hole, is provided with rotating shaft 6 in through hole, and the two ends of rotating shaft 6 are connected on the bearing of fixing device 3, and rotating shaft 6 is by screw fixing device 3.
Rotating shaft 6 is fixed by screw so that snap ring 5 is detachable by the way of rotating shaft 6 is fixed in fixing device 3, it is simple to the replacing of snap ring 5.
As it has been described above, the present invention can preferably be realized.
