Abstract

The utility model discloses an insert top driving drilling device of self clamping back tongs reverse torque beam and consists of a positive speed gearbox, a rotary head, an upper connector and back tongs. The end of the positive speed gearbox, which is connected with the rotary head is provided with a blind hole and a pin roll hole that is perpendicular with the blind hole, the fixing sleeve of the rotary head inserts into the blind hole and is fixed by a pin roll; the back tongs are provided with a back tongs fixing sleeve, a pair of trolleys, a rotary bracket that is used for installing the trolley and a tong teeth that is arranged on the rotary bracket; the utility model is provided with an insert type fixing sleeve and back tongs reverse torque beam and realizes the function of reverse torque when the axial load provides rotation, thus, the utility model has smaller size and is convenient to be disassembled and repaired.

Description

From clamping back-up tong reaction torque Beam plug-in type top-drive drilling
Technical field
The utility model relates to oil-well rig, specifically, relates to a kind of top-drive drilling of oil drilling.
Background technology
Top-drive drilling is the state-of-the-art technology of current oil drilling equipment, can make that accident rate significantly reduces in the drilling well, saves drilling time, improves drilling efficiency, saves cost, makes the spudder realize revolutionary breakthrough.This kind matching requirements reduction box with swivel head fixed cover and being connected of back-up tong reaction torque support have dependable performance, compact conformation, size is little to wait requirement.Because existing back-up tong is being set under the torque condition, the pressure when clamping is fixed, even joint screw thread does not need big moment of torsion like this to dismantle, also need apply bigger pressure, cause the damage of joint easily, and its size is bigger.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of compact conformation is provided, and clamps back-up tong reaction torque Beam plug-in type top-drive drilling certainly.
The utility model relates to from clamping back-up tong reaction torque Beam plug-in type top-drive drilling, comprises reduction box, swivel head, top connection, back-up tong.The pin hole that the end that described reduction box is connected with swivel head has blind hole and vertical blind hole, the fixed cover of described swivel head inserts in the blind hole, and pin is fixed; Described back-up tong has the back-up tong fixed cover, be arranged on a pair roller in the cover, the rotary bracket of roller is installed and be arranged on pincers tooth on the rotary bracket.
The radius of curvature of the inner surface of described back-up tong fixed cover diminishes to both sides gradually from the two-end-point of a diameter, until another perpendicular diameter, the gap of the inner surface of back-up tong fixed cover and the external surface of tool joint from large to small, two semicircles are symmetrical.
Described in the utility model have plug-in mounting cover and back-up tong reaction torque support from clamping back-up tong reaction torque Beam plug-in type top-drive drilling, can bear drilling well or the axial load when making a trip, and the shackle reaction torque in when rotation is provided, and, dismounting and easy to maintenance littler than existing plant bulk.
Description of drawings
Fig. 1 is described in the utility model from clamping back-up tong reaction torque Beam plug-in type top-drive drilling front view;
Fig. 2 is an A-A sectional drawing among Fig. 1, and expression is in vacant state;
Fig. 3 is an A-A sectional drawing among Fig. 2, and expression is in the shackle state.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the back-up tong of the clamping certainly reaction torque Beam plug-in type top-drive drilling shown in the utility model comprises reduction box 1, swivel head 4, top connection 5, back-up tong 6.The pin hole that the end that described reduction box 1 is connected with swivel head 4 has blind hole and vertical blind hole, the fixed cover 3 of swivel head 4 inserts in the blind hole, and pin 2 is fixed; Described back-up tong 6 has back-up tong fixed cover 7, is arranged on the pair roller 9 in the cover, and the rotary bracket 8 and the pincers tooth 10 that is arranged on the rotary bracket of roller is installed.This back-up tong tightens together top connection 5 and tool joint 11.
Referring to Fig. 2, the radius of curvature of the inner surface of described back-up tong fixed cover 10 diminishes to both sides gradually from the two ends of a diameter a-a, until another perpendicular diameter b-b, the gap that makes back-up tong fixed cover 7 inner surfaces and tool joint 11 and top connection 5 external surfaces from large to small, two semicircles are symmetrical.When the pincers tooth is positioned at a point of gap maximum, promptly during the room, rotary bracket 8 can drive left and right rotation by hydraulic motor.See Fig. 3, contact when pincers tooth 8 forwards to tool joint 11 that the hydraulic motor setting pressure is locked it, and an initial clamping force is provided, shackle is finished in top connection this moment 5 rotations.Last shackle moment of torsion is big more, and pincers tooth and tool joint contact pressure are big more, otherwise, more little.
Certainly the back-up tong 6 that clamps back-up tong reaction torque Beam plug-in type top-drive drilling described in the utility model is finished shackle by the 8 left and right rotations of hydraulic motor driven rotary carriage, therefore is also referred to as the self-clamp type back-up tong.
Use the self-clamp type back-up tong, when making on the back-up tong pincers tooth shackle, locked voluntarily torque of pressing shackle needs on the joint, applying moment of torsion gets final product, that is to say when the shackle moment of torsion is big on the joint, the pressure of pincers tooth butt joint also increases, and shackle moment of torsion hour on the joint, the pressure of pincers tooth butt joint also reduces thereupon.
