Description
Affiliated technical field
The utility model belongs to oil drilling facility parts, is meant a kind of manual assembly of ram preventer that is used on the oil drilling especially.
Background technology
Preventer is the visual plant in the modern oil drilling, and it mainly acts on is the generation that prevents gas blowout accident in drilling process.Ram preventer is a kind of of preventer, and the oil cylinder that it is mainly closed by pressure-bearing shell, side door, flashboard, driving flashboard, the lock portion at oil cylinder rear portion, manual assembly etc. are formed.The function of the manual assembly of preventer is after blowout preventer hydraulic is closed, and pins flashboard axis with manual mode, and the flashboard accident is opened when preventing the hydraulic pressure disappearance, is the auxiliary safety device of preventer.Existing product is generally all used the method for tight screw, realizes connecting of hand control part and preventer lock shaft, on-the-spotly installs, dismounting is all cumbersome; Versatility is relatively poor, and the preventer scope that is suitable for is narrower.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, provides a kind of improved ram preventer manual assembly, and it is simple in structure, has stronger versatility, and result of use is good.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model includes: cruciform joint, crosshead shoe, slider pin, lock shaft joint.End at the lock shaft joint is connected with crosshead shoe, slider pin, is connected with cruciform joint in the outer end of crosshead shoe.It is characterized in that: at the lock shaft joint area, also have operating sleeve, lock pin, spring, ball stud, locking axle, spring base, elastic spring, at the inner slide block lock pin in addition of crosshead shoe.Wherein ball stud is movably connected on the right of lock shaft joint, the locking axle is movably connected on the inside of lock shaft joint, the locking axle is connected with spring, spring base, elastic spring, lock pin, and lock pin is connected with the operating sleeve that is positioned at the joint outside, and slider pin is made axial restraint by the slide block lock pin.
The utility model is taked technique scheme, has following beneficial effect: pull back operating sleeve during installation, the locking axle retreats, ball stud is in free state, and can insert lock shaft this moment with the lock shaft joint, behind the unclamp operation cover, the locking axle moves forward under spring action, and ball stud is pinned.The bulb lock is charged into the annular groove of lock shaft correspondence, and installation can be finished.During dismounting, pull back operating sleeve, axle retreats release, and extract whole assembly and get final product this moment.
The utility model can be realized Fast Installation and dismounting, and versatility is good, can adapt to the preventer of a plurality of series.
