Description
Technical field
The present invention relates to field of fixation devices, particularly, relate to a kind of fixing clamping device.
Background technology
in the recovery process of oil, drilling rod is a kind of requisite instrument, because oil well is general all darker, so the drilling rod of recover petroleum 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, then needs split the drilling rod damaged by fastening devices after first being fixed by the two ends drilling rod damaging drilling rod.Existing fastening devices all adopts the cylinder clamping drilling rod of hollow usually, and fluid pressure type drive unit drives the fastening devices of fixing drilling rod to rotate, and fastening devices drives drilling rod to rotate in the axial direction again, thus drilling rod is split.Existing fastening devices is circular ring structure, and the inwall of circular ring structure is provided with flank, and existing fastening devices needs drilling rod to insert in annulus when clamping drilling rod, and drilling rod when the clamp operation longer for length is more difficult; Existing fastening devices is easy and drilling rod generation skidding when clamping drilling rod, and make drilling rod can not realize the fractionation of drilling rod along with fastening devices rotation, existing fastening devices exists the problem that operation when fixing drilling rod is inconvenient, clamp easily skidding.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of fixing clamping device, operates inconvenience, the easy problem of skidding of clamping to overcome when existing fastening devices fixes drilling rod.
The present invention's adopted technical scheme that solves the problem is: a kind of fixing clamping device, comprise snap ring body, snap ring body outer wall is provided with fixed block, snap ring body comprises two symmetrically arranged snap rings, snap ring is provided with the beginning, blind end, the blind end of two snap rings is provided with loose-leaf, the beginning of two snap rings is provided with and screw rod, the fixed head that nut coordinates, fixed head is provided with some tapped through holes, multiple groove is offered in snap ring, resetting-mechanism is provided with in groove, resetting-mechanism upper end arranges grip block, grip block is provided with clamping face, clamping face caves inward into cambered surface, the radian of cambered surface coordinates with drilling rod, cambered surface is provided with flank.Because snap ring is provided with the beginning, when clamping drilling rod, first the beginning of snap ring is opened, by drilling rod by beginning insertion two snap ring, the beginning in snap ring is closed, with screw rod through tightening with nut again after tapped through hole, multiple screw rod and nut with the use of drilling rod well being fixed, make the insertion of drilling rod more convenient, cambered surface on grip block is arranged so that the contact surface of grip block and drilling rod is larger, and cambered surface is set to flank, make that there is between drilling rod and cambered surface larger frictional force, further add the contact stabilization of drilling rod and grip block, because grip block is connected to resetting-mechanism, resetting-mechanism controls grip block stretching in groove, between holding drill pipe, resetting-mechanism controls grip block in groove, when needs clamping drilling rod, resetting block is driven to make grip block eject groove, thus make grip block clamp drilling rod, the present invention is by being set to the snap ring of two symmetries by snap ring body, the blind end loose-leaf of two snap rings connects, beginning is connected with screw fit by screw rod, make the beginning of snap ring can open with closed freely, be convenient to the insertion of drilling rod, overcome existing fastening devices not easy-operating problem when inserting drilling rod, by arranging the grip block controlled by resetting-mechanism in snap ring, and the clamping face of grip block is set to the cambered surface that coordinates with drilling-rod external wall radian, overcomes the problem that existing fastening devices is easily skidded when clamping drilling rod.
Further, resetting-mechanism is spring, and described groove inner wall is provided with baffle plate.Spring is by baffle controls, and baffle controls elongation and the compression of spring, and spring makes spring meet resetting-mechanism with regard to elasticity and recovery capability and controls grip block stretching in groove.
Further, resetting-mechanism is piston structure.Piston structure has the function of shrinking and ejecting, and can meet resetting-mechanism and control grip block stretching in groove.
Further, groove is provided with 6.If groove is arranged very little, corresponding grip block is also just fewer, grip block very little can not well by drill-rod clamping, the groove offered is too much, the structural stability of snap ring may be had influence on, make snap ring can not support too much grip block, 6 structural stabilities can guaranteeing snap ring, again can well by drill-rod clamping.
Further, fixed head is welded on snap ring outer wall.The mode of welding is comparatively firm, avoids the phenomenon that when two snap rings close, generation junction plate comes off, improves stability when two snap rings close.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is by being set to the snap ring of two symmetries by snap ring body, the blind end loose-leaf of two snap rings connects, beginning is connected with screw fit by screw rod, make the beginning of snap ring can open with closed freely, being convenient to the insertion of drilling rod, overcoming existing fastening devices not easy-operating problem when inserting drilling rod.
2, the present invention by arranging the grip block controlled by resetting-mechanism in snap ring, and the clamping face of grip block is set to the cambered surface that coordinates with drilling-rod external wall radian, overcomes the problem that existing fastening devices is easily skidded when clamping drilling rod.
3, the present invention is by being welded on snap ring outer wall by fixed head, avoids the phenomenon that when two snap rings close, generation junction plate comes off, improves stability when two snap rings close.
