Abstract

The invention belongs to the technical field of oil drill, in particular relates to a lifting system of a hollow traveling block drill, which comprises an overhead traveling crane (8), a drill table (2), a lifting member (3), a racking platform (4), a slip fixedly arranged on the drill table (2) and a pipe setback (6) fixedly arranged on the drill table (2); the lifting system is characterized in that a mechanical discharge device is fixedly arranged on the racking platform (4); the mechanical discharge device comprises a longitudinal working arm (12), a pipe setback clamp (11) fixedly connected with the longitudinal working arm (12) and a support block (13) connected with the racking platform (4); and the support block (13) is sheathed above the longitudinal working arm (12) and can move along the longitudinal direction of the support block (13). The mechanical discharge device is adopted in the hollow traveling block drill; therefore, the lifting system can carry out pipe tripping on the drill for automatically arranging the pipe setback to save the time and labor; and the lifting system is safe and efficient and overcomes the disadvantage of the existing drill that the pipe setback is manually arranged.

Description

Hollow tourist bus hoisting system of rig

Technical field

The invention belongs to the oil-well rig technical field, particularly a kind of hollow tourist bus hoisting system of rig.

Background technology

Existing Hoisting System that rig is joined is integrated not high with the optimization degree in whole drilling process, and it is oversize that particularly the rig round trip accounts for whole drilling time, and Hoisting System will be interrupted operation, and efficient is low.And need several workmans to operate simultaneously, not only waste time and energy, and need more operator, moreover the workman (sees accompanyingdrawing 1～Fig. 4) in that work high above the ground is very dangerous.Fig. 1～Fig. 4 has described existing rig and has once played the thribble operation process.Fig. 1 mentionsdrill string 7 for liftingmember 3 fromrig table top 2; Fig. 2 isdrill string 7 referred quadruple board platforms 4 positions (a thribble height), andslips 5 blocks drill string, andtong 1 shackle is unsnatched button back liftingmember 3 and must be carried the posture in standing (qigong) root; Could be descending after Hoisting System must wait thribble to discharge; Fig. 3 requires the position forrig table top 2 workmans put the thribble lower end topipe setback 6; The rig table top needs at least two workman's operations; Fig. 4 requires position (quadruple board platform needs workman's work high above the ground) for quadruple board platform 4 workmans put the thribble upper end to quadruple board platform 4, and liftingmember 3 goes downwards torig table top 2 and prepares to rise the thribble operation next time.

Existing as can be seen hoisting system of rig is to be interrupted operation in the whole process that makes a trip.

Summary of the invention

The present invention is intended to overcome the deficiencies in the prior art part and a kind of thribble of discharging automatically when rig makes a trip is provided, and shortens the hollow tourist bus hoisting system of rig of rig trip time

For achieving the above object, the present invention is achieved in that

A kind of hollow tourist bus hoisting system of rig, it comprises overhead traveling crane, rig table top, lifting member, quadruple board platform, be fixed at the slips on the rig table top and be fixed at pipe setback on the rig table top; On described quadruple board platform, be fixed with mechanical ejector; Described mechanical ejector comprises vertical working arm, the thribble anchor clamps that are fixedly connected with vertical working arm and the back-up block that joins with quadruple board platform; Described back-up block is socketed on vertical working arm, and vertically working arm can vertically move along back-up block.

As a kind of preferred version, back-up block of the present invention can laterally slide along quadruple board platform.

As another kind of preferred version, the present invention can be provided with the thribble passage on described lifting member.

The present invention is owing to adopted mechanical ejector in hollow tourist bus rig, Hoisting System can make rig make a trip and discharge thribble automatically, and is time saving and energy saving, safe and efficient, has overcome the deficiency of existing rig by manpower discharging thribble.

The specific embodiment

Referring to Fig. 5～shown in Figure 6, hollow tourist bus hoisting system of rig, it comprises overhead traveling crane 8,rig table top 2,lifting member 3, quadruple board platform 4, be fixed at theslips 5 on therig table top 2 and be fixed atpipe setback 6 on therig table top 2; On described quadruple board platform 4, be fixed with mechanical ejector; Described mechanical ejector comprisesvertical working arm 12, thethribble anchor clamps 11 that are fixedly connected withvertical working arm 12 and the back-upblock 13 that joins with quadruple board platform 4; Described back-upblock 13 is socketed onvertical working arm 12, and vertically workingarm 12 can vertically move along back-upblock 13.

Back-upblock 13 of the present invention can laterally slide along quadruple board platform 4.For making operation more smooth and easy, the present invention is provided withthribble passage 14 on describedlifting member 3.

Referring to Fig. 5, be hollow tourist bus hoisting system of rig arrangement diagram, it mainly is made up ofhollow lifting member 3 and the mechanical ejector that can all around move.

Fig. 6～Fig. 8 once plays the thribble operation process for hollow tourist bus hoisting system of rig.

Fig. 6 mentionsdrill string 7 to quadruple board platform 4 positions (a thribble height) for liftingmember 3 fromrig table top 2, and slips 5 blockswhole drill string 7;

Fig. 7 is that lifting member is descending, and mechanical ejector is prepared to grab thribble, andtong 1 shackle is unsnatched button back mechanical ejector and caught thribble;

Fig. 8 goes downwards torig table top 2 for liftingmember 3, and mechanical ejector is discharged thribble automatically, and liftingmember 3 prepares to rise the thribble operation process next time.Hoisting System does not need to pause and just begins to rise the thribble operation next time.
