Abstract

The utility model provides a three-joint unit centering device, which comprises a bottom plate, a rack, two centering claws, a clamping hydraulic cylinder and an inclined hydraulic cylinder. The rack is arranged on the bottom plate through a support seat and a pin shaft A; the middle parts of the two centering claws are symmetrically arranged on the rack through a pin shaft C; the front ends of the two centering claws are arc-shaped, and the two ends of the clamping hydraulic cylinder are respectively hinged with the rear ends of the two centering claws; the rack is provided with a pin shaft B parallel to the pin shaft A; and the two ends of the inclined hydraulic cylinder are respectively hinged with the pin shaft B and the bottom plate. The device has a simple structure. An inclined three-joint unit can be centered in advance so as to be grabbed accurately by a pipe arrangement device. Therefore, the pipe can be automatically arranged on or removed from a drilling platform and can be automatically discharged, and the direct contact of people and the three-joint unit can be avoided. The device has a simple and reasonable overall structural design, high bearing capacity and a high degree of mechanization and is safe to operate, the labor can be saved, the efficiency can be increased, and the device is suitable for for being matched with various drilling platforms.

Description

The thribble erection device
Technical field
The utility model relates to the device that is used to set upright thribble in a kind of oil drilling, particularly a kind of erection device that is used for the thribble discharging.
Background technology
Thribble is to be joined end to end by two to five drilling rods to form.In the oil drilling process, thribble is transferred to well head or thribble is transferred to the discharging frame from well head from the discharging frame is the operating process of an indispensability.The handover of thribble at present, discharging are usually by manually finishing, and be not only dangerous high, and labour intensity is big, inefficiency.In recent years, people have researched and developed the automatic handover tapping equipment of thribble, to reduce working strength of workers, to increase work efficiency, but owing to the problem of swing in the handover process of thribble, can occur, and irregular, the oblique arrangement of thribble on the discharging frame, make the catching robot of tapping equipment can't accurately grasp thribble, still need manually set upright thribble, therefore potential safety hazard still exists, and operating efficiency remains further to be improved.
Summary of the invention
For overcoming the deficiencies in the prior art part, the utility model provide a kind of rational in infrastructure, set upright thribble, effectively increase work efficiency and the thribble erection device of security reliability.
The technical scheme that its technical problem that solves the utility model adopts is: comprise base plate, frame, set upright pawl, clamping hydraulic cylinder and hydraulic tilt cylinder; Described frame is installed on the base plate by supporting seat and bearing pin A, and frame can be rotated around bearing pin A; Two middle parts of setting upright pawl are loaded on the frame symmetrically by bearing pin C, and set upright pawl and can rotate around bearing pin C; Two front ends of setting upright pawl are curved, and the two ends of clamping hydraulic cylinder are hinged with two rear ends of setting upright pawl respectively, make two to set upright pawl and can and unclamp the action of thribble with the flexible realization obvolvent thribble of clamping hydraulic cylinder; On frame, be provided with the bearing pin B that is parallel to bearing pin A; The two ends of hydraulic tilt cylinder are hinged with bearing pin B and base plate respectively, thereby make frame realize having a down dip with flexible can the rotation around bearing pin A of hydraulic tilt cylinder, and set upright thribble better.
The beneficial effects of the utility model are: it is rational in infrastructure, can in advance the thribble that tilts be set upright, so that pipe racking device grasps thribble accurately, realized the rig floor and discharging up and down automatically automatically of thribble, avoided the people to contact, its overall construction design advantages of simple with the direct of thribble, supporting capacity is strong, the mechanization degree height is controlled safety, saves manpower, is raised the efficiency, and is suitable for the supporting use of various offshore boring island.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be Fig. 1 vertical view.
Among the figure: 1 for clamping hydraulic cylinder, 5 for hydraulic tilt cylinder, 6 for base plate, 7 for supporting seat, 8 bearing pin As, 9 for bearing pin B, 10 for Connection Block, 11 is bearing pin D for bearing pin C, 4 for setting upright pawl, 2 for frame, 3.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Thribble erection device described in the utility model comprises base plate 6, frame 2, sets upright pawl 1, clamping hydraulic cylinder 4 and hydraulic tilt cylinder 5; Described frame 2 is installed on the base plate 6 by supporting seat 7 and bearing pin A8, and frame 2 can be rotated around bearing pin A8; Two middle parts of setting upright pawl 1 are loaded on the frame 2 symmetrically by bearing pin C3, set upright pawl 1 and can rotate around bearing pin C3; Two front ends of setting upright pawl 1 are curved, and the two ends of clamping hydraulic cylinder 4 are hinged with two rear ends of setting upright pawl 1 respectively, make two to set upright pawl 1 and can and unclamp the action of thribble with the flexible realization obvolvent thribble of clamping hydraulic cylinder 4; On frame 2, be provided with the bearing pin B9 that is parallel to bearing pin A8; The rear end of hydraulic tilt cylinder 5 is hinged by Connection Block 10 and bearing pin D11 and base plate, and the front end of hydraulic tilt cylinder 5 and bearing pin B9 are hinged, thereby makes frame 2 realize having a down dip with flexible can the rotation around bearing pin A8 of hydraulic tilt cylinder 5, sets upright thribble better.
During use, base plate 6 of the present utility model is fixed in thribble transfers on the tapping equipment, when thribble swing occurred or tilts, clamping hydraulic cylinder 4 stretched, and drives two and sets upright pawl 1 obvolvent thribble; Simultaneously, hydraulic tilt cylinder 5 is done to stretch or contractile motion, regulate the gradient of frame 2, thribble is set upright, be convenient to thribble handover tapping equipment and grasp thribble accurately, realize the automatically up and down rig floor of thribble and discharging automatically, thereby avoided contacting of people and thribble, improved security reliability and operating efficiency.
