Description

The artificial pipe coupling pre-screwing device that can float and regulate

Technical field

The utility model relates to a kind of petroleum pipeline processing unit (plant), specifically the pre-connection device of twisting of the oil casing collar of relevant a kind of petroleum pipeline.

Background technology

The pre-two kinds of technology that are connected to of twisting of present oil casing collar.A kind of is full-automatic pre-stubborn technology, as long as the pipe box cupling is placed in the blow tank of pre-stubborn machine, equipment will complete material loading, clamping automatically, the pre-whole process that connects of twisting.What seamless steel tubing mill's Tube processing line line adopted at present is exactly this technology.Technique equipment complexity, investment cost is high.Another kind is the manual pre-connection technology of twisting, and technique equipment is simple, and investment cost is low.In the manual technology of tightening in advance, it is the artificial pipe coupling pre-screwing device that adopts as shown in Fig. 1 a and Fig. 1 b.Should manually manage the coupling pre-screwing device, with for example swiveling wheel 4 work that matches of tubing and casing rotating mechanism, should comprise by artificial pipe coupling pre-screwing device: base 1, be arranged on travelling car 2, pipe box cupling clamp mechanism 20 on base 1, connect the rigid support 3 of described clamp mechanism 20 and travelling car 2, clamp mechanism 20 comprises V-shaped groove 9, grasping firmly pincers 7 and clamping cylinder 10, and V-shaped groove 9 is for disposed tubes box cupling 6.

Artificial running of managing the coupling pre-screwing device is: first by manually pipe box cupling 6 being placed on the V-shaped groove 9 of pre-screw device, and by pipe box cupling clamping cylinder 10 driving grasping firmly pincers 7, pipe box cuplings 6 are clamped; Wait to twist tubing and casing 5 and connect station by carrying step rate to send into pre-twisting, after tubing and casing comes to a complete stop, twist in advance swiveling wheel 4 and start to drive the tubing and casing rotation; Promote travelling cars 2 and advance this moment by manually pinching trammer handle 8, and travelling car 2 moves forward on base 1, tubing and casing 5 bodys rotations like this, 6 reaches of pipe box cupling, pipe box cupling 6 head of tubing and casing 5 of just having screwed on; When tubing and casing 5 is stopped the rotation, cut off the power supply of swiveling wheel 4, swiveling wheel 4 stops the rotation, and with cylinder 10, unclamps and embraces pincers 7, manually pinches trammer handle 8 travelling car 2 is retracted to original position.Complete like this and once manage the pre-termination process of twisting of box cupling 6.

But in artificial pipe coupling pre-screwing device running, the head-bent of part tubing and casing 5 (in the machining accuracy scope), due to adjustings of can not floating of this support, cause pipe box cupling 6 and tubing and casing 5 screw threads to not going up, and can't twist and connect; Also can damaged screw when serious, cause pipe box cupling 6 to scrap, body screw thread processing again that must excision tubing and casing 5.In the stubborn termination process of pipe box cupling 6, whole being screwed in advance is equipped with shaking phenomenon in addition.
