Description

All-hydraulic combined type thread screw on and-off machine

Technical field

The utility model relates to the be threaded improvement of thread screw on and-off machine of a kind of pipe fitting, specifically is a kind of all-hydraulic combined type thread screw on and-off machine, is applicable to being threaded of oil pipe, engineering geology, the hydrology, power station dam and various types of drilling engineering pipe fitting.

Background technology

Known to the research of applicant's professional production: the drawback that existing same category of device product exists mainly shows: pipe clamps to go up and adopts gear drive, the gear drive meeting causes drive gap because drive disk assembly, one section post gap change in period is big using, driving torque is subjected to the drive disk assembly intensity effect, equipment is created in twist may produce in the button process skid, phenomenon such as instability, be unfavorable for long-term and twist button work fast; Fixing pincers part, on fixing pincers synchronized cylinder frame is fixing, adopt single main support plate to support, because synchronized cylinder support gravity effect, simultaneously in twisting the button process under the huge torsional interaction, make fixing pincers and move the pincers journal offset, fixing pincers are worked under the out-of-alignment state with mobile pincers can reduce operating efficiency, adopt single main support plate to support the synchronized cylinder support simultaneously, also have problems on the intensity of whole fixedly pincers, so increase support strength at the big and long gusset of main support backboard face welding, but main support plate single load bearing problem still exists, and also influences overall appearance, and the spinner angle of fixing pincers generally fixes on 40 ° in addition, less than normal; Move the pincers part, same category of device is the four rolling seat to be welded on move on the pincers two stands plate lateral surface or be welded on the bearing, disposable regulating moved pincers and lathe bed gap during installation, bad just to have begun to occur the gap too big or too little and influence spinner work if regulate, later stage uses the intermediate gap can be increasing, make whole mobile pincers in the spinner process to radially being offset than wide-angle, produce two disalignment that is threaded of pipe, both influence operating efficiency, and may damage pipe; The centering supporting structure simply and is not regulated benchmark, so can not accurately locate pipe at fixing pincers and the axis that moves in the pincers, can not make pipe axial line and fixing pincers guarantee coaxial with the work axial line that moves pincers, like this, act on pipe be threaded the part on spinner moment just do not get twice the result with half the effort, also can damage pipe screw thread and pipe itself, cause serious quality accident.

Summary of the invention

The purpose of this utility model is the drawback at above-mentioned prior art equipment, and the improved technical solution that proposes and develop the more excellent all-hydraulic combined type thread screw on and-off machine of a kind of performance.

The purpose of this utility model is to realize by following technical solution: comprise the lathe bed that is installed on the mattess and on fixedly pincers with move pincers, move hydraulic motor, the centering support in the pincers and revolve mechanism soon, promptly adopt the synchronized cylinder support of two main support plates and duplex bearing support fixation pincers, below two main support plate inboards, diaxon bearing, be welded with bearing rib, the spinner angle initialization of fixing pincers is 50 °, moves on the roller mount below the pincers supporting plate adjustable for height roller set and fine setting drift are installed.

On the track that described mobile pincers are installed in can be axially movable, be welded as a whole with lathe bed, the centering support is fixed on and moves the pincers side.

Described centering support is provided with pulley, has the graduation mark and the caliber adjustment screw of regulating benchmark on its panel.

Adopt ring flange to fix with high-strength bolt on the synchronized cylinder of described fixedly pincers and mobile pincers, rotary oil cylinder and main support plate are hinged.

Described fixedly pincers move pincers, centering support and revolve mechanism soon and all adopt dismountable combining structure.

Useful good effect of the present utility model is: owing to adopt the synchronized cylinder support of two main support plates and duplex bearing support fixation pincers, in two main support plate inboards, be welded with bearing rib below the diaxon bearing, allow synchronized cylinder support center of gravity between two main support plates, like this gravity of synchronized cylinder frame by bearing rib to lower stress, greatly increased the fixedly bulk strength of pincers, on the aesthetic feeling of outward appearance, be improved again, solved rocking and the out-of-alignment problem that the spinner gap causes, synchronized cylinder support smooth rotation in duplex bearing in the work, the spinner resistance is very little, make service behaviour very stable, increased fixedly pincers spinner angle, can disposablely to greatest extent unclamp screw thread like this, operating efficiency greatly improves; At mobile pincers four groups of adjustable height rollers and fine setting drift are set, when mounted can be according to needs are installed, be adjusted to very accurate gap, and can be after the user uses the regular period, after fine setting has been adjusted to range, only need lifts and move pincers, unclamp 12 high-strength bolts of fixed idler whell seat, can readjust best clearance easily, assurance equipment is in good working order always; The pulley that the centering support is provided with, the graduation mark and the caliber adjustment screw of regulating benchmark can accurately be located the pipe center line, guarantee that pipe center line and thread screw on and-off machine center line are concentric, moment of torsion in the spinner process will all affact on the pipe connecting thread like this, make working stability, and operating efficiency improves; Fixing pincers move pincers, and centering support and revolve mechanism soon and all adopt dismountable combining structure uses high-strength bolt and equipment lathe bed to fix, and accurate adjusting play when promptly being convenient to first Installation and Debugging also can make things convenient for the user to use the back maintenance for a long time and keeps in repair; In a word, the utility model has strengthened device ', has improved operating efficiency, has strengthened the job stability of equipment long-term work, and outward appearance is more coordinated, and is more attractive in appearance.
