Abstract
The utility model relates to steel wire rope connecting equipment, in particular to an anti-drop mechanical clamp type rope cap capable of realizing rapid replacement. The technical scheme is that the anti-drop mechanical clamp type rope cap mainly consists of a cap hood, a rope wedge, a jackscrew joint, an anti-dropping sleeve, an anti-drop pin, a cap body, a bearing and a steel wire rope, wherein the rope wedge is fixed in an inner cavity of the cap hood; one end of the jackscrew joint is connected with the cap hood, and the other end of the jackscrew joint is connected with the cap body; the jackscrew joint pushes against the rope wedge so that the steel wire rope can be tightly fixed in the inner cavity of the cap hood; and the bearing is arranged between the jackscrew joint and the cap body. The anti-drop mechanical clamp type rope cap has the beneficial effects that the structure is simple, the use is convenient, a downhole tool is connected with the steel wire rope conveniently and safely, the steel wire rope can not be twisted when in work, and the steel wire rope can be replaced conveniently and rapidly, thereby relieving the labor intensity of workers and improving the working efficiency.
Description
Technical field
The utility model relates to a kind of wire rope connection device, particularly a kind of quick replacing slip-off preventing clip type rope socket.
Background technology
In the field produces, oil pumper connects downhole tool through wire rope at present, makes oil go out well through the way of pressurizeing; Mechanical block-relief oil production device in the oil well utilizes the periodic elastic deformation of tubing string to produce periodically exactly and pumps; Thereby the stratum is produced the piston action that frequent checker is pushed in suction, and downhole tool and wire rope connection is at present adopted and is inserted the plumbous formula rope socket of filling, and connection is wasted time and energy; Use inconvenience, inefficiency.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of quick replacing slip-off preventing clip type rope socket is provided, and simple in structure, easy to use, steel rope replacing is convenient, fast.
Its technical scheme is: mainly by calotte, rope wedge, jackscrew joint, anti-ly press-off, locking pin, body, bearing, wire rope form; The rope forelock is in the inner chamber of calotte; Jackscrew joint one end connects calotte; The other end connects body, and the jackscrew joint withstands the rope wedge and wire rope is fixed on tightly in the inner chamber of calotte, is provided with bearing between described jackscrew joint and the body.
The junction of above-mentioned calotte and jackscrew joint is provided with locking pin and press-offs with anti-.
The beneficial effect of the utility model is: simple in structure, easy to use, and safety easy to connect between downhole tool and the wire rope, wire rope can not beaten and turn round during work, and steel rope replacing is convenient, fast, has alleviated working strength of workers, has improved operating efficiency.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: calotte 1, rope wedge 2, jackscrew joint 3, anti-ly press-off 4, locking pin 5, body 6, bearing 7, wire rope 8.
The specific embodiment:
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly by calotte 1, rope wedge 2, jackscrew joint 3, anti-ly press-off 4, locking pin 5, body 6, bearing 7, wire rope 8 form; Rope wedge 2 is fixed in the inner chamber of calotte 1; Jackscrew joint 3 one ends connect calotte 1; The other end connects body 6, and jackscrew joint 3 withstands rope wedge 2 and wire rope 8 is fixed on tightly in the inner chamber of calotte 1, is provided with bearing 7 between described jackscrew joint 3 and the body 6; The junction of described calotte 1 and jackscrew joint 3 is provided with locking pin 5 and press-offs 4 with anti-.
This rope socket relies on self-locking cone angle of its rope wedge 2 wire rope 8 tightly to be stuck in the inner chamber of calotte 1, and the jackscrew joint 3 of rope wedge 2 bottoms plays preparatory wedging, and its clamping force increases along with the increase of steel wire rope tension, and wire rope in clamping securely all the time.In use, the pretightning force of jackscrew joint 3 can be eliminated because of the further wedging of rope wedge 2.Although the rope socket bottom is provided with bearing 7, jackscrew joint 3 still has the possibility of back-off.Therefore, for eliminating this accident potential, also designed locking pin 5 in the rope socket part and press-offed 4 with anti-, so downhole tool is when work, wire rope 1 can not take place to beat the phenomenon of turning round, and is very easy to during change steel rope more yet, has improved operating efficiency.
