Abstract
The utility model discloses a hydraulic cathead which relates to equipment used in the process of oil exploration on land and on the sea, and the hydraulic cathead solves the defects existing in other techniques. The utility model has the main structures that a hydraulic cylinder is arranged on a support saddle, and a traveling block is arranged on a cylinder rod of the hydraulic cylinder; a central shaft of the traveling block is clamped in a guide groove of a pulley guide plate which is arranged on the support saddle, and a fixed seat of a fixed pulley is welded with a sleeve of a knuckle pin; the centre of a wire rope of the movable rope is linked with the center of a wire rope of the fixed pulley to penetrate the axle centre of the knuckle pin, and the fixed seat of the fixed pulley and the centre of gravity of the pulley form an obtuse angle; the fixed pulley is fixed on the fixed seat of the fixed pulley.
Description
One, technical field: the utility model relates to equipment, the especially hydraulic catwork that uses in a kind of land and the offshore oil exploration process.
Two, background technology: at present, in the drilling prospection process, be used for equipment machinery, the shackle operation such as drilling rod, drill collar, sleeve pipe and have two kinds usually, a kind of method of old-fashioned manpower driving device cat head rotates to an angle tongs and finishes, the operating type of this backwardness not only labour intensity is big, potential safety hazard is many, and production efficiency is low; Another kind is hydraulically powered rotation cat head, though it has alleviated working strength of workers, the rope stretching angle of wire rope can not be adjusted, and has limited the scope of application of tong, and production efficiency is still not high, and steel rope abrasion is serious, and application life is low.
Three, summary of the invention: the purpose of this utility model provides a kind of hydraulic catwork simple in structure, esy to use, safe and reliable, it has solved the shortcoming that other technology exists, the purpose of this utility model is achieved in that it is to be connected by bearing, hydraulic cylinder, movable pulley, movable pulley guide strip, fixed pulley, fixed pulley holder, king pin, king pin cover to form.Hydraulic cylinder is installed on the bearing, movable pulley is installed on the piston rod of hydraulic cylinder, the central axis of movable pulley is stuck in the gathering sill of pulley guide strip, the movable pulley guide strip is installed on the bearing, fixed pulley holder and turn to guide welding, the movable pulley wire rope center and the fixed pulley wire rope line of centres pass the axle center of king pin, fixed pulley holder and pulley center of gravity form the obtuse angle, and fixed pulley is fixed on the fixed pulley holder.
Operating principle of the present utility model is: the anchor head steel wire loop is at the afterbody of big pliers grip, during shackle, hydraulic cylinder piston rod stretches out, the movable pulley that is installed on the hydraulic cylinder rises along the gathering sill of pulley guide strip, making wire rope affect tong revolution certain angle to finish by movable pulley and fixed pulley buckles or the shackle action, the fixed pulley holder can also rotate to an angle according to the particular location of tong, and the rope stretching angle of fixed pulley is big, can be because of the height wearing and tearing wire rope of big pliers grip.The piston rod of hydraulic cylinder is return when resetting, and returns the rope spring wire rope is resetted.
Owing to adopted technique scheme, this use is novel to have following advantage:
1, the fixed pulley holder can rotate to an angle, and wire rope is vertical with big pliers grip all the time, satisfies the well site needs to a greater extent.
2, fixed pulley holder and pulley center of gravity form the obtuse angle, can be because of the height of big pliers grip, and the wearing and tearing wire rope has improved the stressing conditions of wire rope, increases the service life.
3, installed the movable pulley guide strip additional, movable pulley can move up and down along gathering sill, increases the intensity of hydraulic cylinder piston rod, prevents the hydraulic cylinder beat.
Four, description of drawings: Fig. 1 is the structural representation of hydraulic catwork; Among the figure: 1, bearing 2, hydraulic cylinder 3, movable pulley 4, movable pulley guide strip 5, fixed pulley 6, fixed pulley holder 7, king pin 8, turn to guide
Fig. 2 is the figure that stretches out of hydraulic catwork;
Fig. 3 is the drawing of site of hydraulic catwork fixed pulley
Five, the specific embodiment: in Fig. 1, the utility model is by bearing 1, hydraulic cylinder 2, movable pulley 3, movable pulley guide strip 4, fixed pulley 5, fixed pulley holder 6, king pin 7, turn to guide 8 to be formed by connecting, hydraulic cylinder 2 is installed on the bearing 1, movable pulley 3 is installed on the piston rod of hydraulic cylinder 2, the central axis of movable pulley 3 is stuck in the gathering sill of movable pulley guide strip 4, movable pulley guide strip 4 is installed on the bearing 1, fixed pulley holder 6 and turn to guide 8 to be welded to connect, the movable pulley 3 wire rope centers and the fixed pulley 5 wire rope lines of centres, pass the axle center of king pin 7, fixed pulley holder 5 forms the obtuse angle with the pulley center of gravity, and fixed pulley 5 is fixed on the fixed pulley holder 6.
