Description

The telescopic arm of a kind of connecting and disconnecting drill rod and sleeve pipe mechanism

Technical field

The utility model belongs to the oil drilling apparatus field, relates to the telescopic arm of a kind of connecting and disconnecting drill rod and sleeve pipe mechanism concretely.

Background technology

Along with the national economic development, the demand of petroleum gas is increasing, and this just requires the exploration and development velocity efficiency to need to improve, in the drilling well drilling process, along with the degree of depth that pierces constantly increases, need constantly on existing drilling pipe, to increase new drilling pipe, be commonly called as " adapter ".Most of operation is all by manually-operated in the adapter process, difficulty is big, the labour intensity height, dangerous big, normally need in mouse hole drilling pipe be connected the drilling pipe that will newly connect then earlier for 3 one group hangs out it by equipment such as hoist lines from mouse hole, move to the upper end of existing drilling pipe in the drilling well, the drilling pipe that newly connects is adjusted to the upper end of vertical direction over against existing drilling pipe, 3 drilling pipes that connect together that newly connect are docked with existing drilling pipe in the drilling well screw the growth of finishing drilling pipe in the drilling well, as above, need in the time of in mouse hole to take over, the pipe that connects also will be connected with the pipe in the drilling well when moving on to the drilling well top, longer owing to drilling pipe itself in said process, heavier, " move ", " seat adjustment " " butt joint screws " cooperates auxiliary mode time-consuming with the people at present, effort efficient is low, labour intensity is big, dangerous high, it is very inconvenient to operate.Especially need by elongating or shortening the clamping part to the drilling pipe adapter, purpose is: 1, adapt to the adapter of drilling pipe at mouse hole or drilling well place diverse location; 2, after finishing, adapter needs to regain clamping part to dodge the mobile operation of other devices, especially hanging of drilling pipe moved, because it is bigger that relevant device all belongs to the space that occupies than relatively large equipment, moving range is limited on rig floor, present equipment takes up space, and greatly especially the scope of clamping part recovery is less, be subjected to the space that the adjusting restriction of its equipment level length all the time can be suitable, influence is hung and action such as is moved.

The utility model content

The purpose of this utility model has provided a kind ofly can improve the telescopic arm adjusting range greatly, make the clamping part total after recovery in the mechanism that unloads compacter, than the connecting and disconnecting drill rod of small occupied space and the telescopic arm of sleeve pipe mechanism.

The technical solution of the utility model is as follows:

The telescopic arm of a kind of connecting and disconnecting drill rod and sleeve pipe mechanism, this telescopic arm comprises outer arm, inner arm, telescopic oil cylinder, and described inner arm is sleeved in the described outer arm, and described telescopic oil cylinder one end is connected with described outer arm, and the other end is connected with the front end of described inner arm; The inner arm that all have slippage slot on described outer arm and the inner arm, passes this slippage slot is provided with spinner pincers back-up block, and this spinner pincers back-up block can move relative to described outer arm and inner arm;

The rear end that also is provided with tooth bar, inner arm in described outer arm is provided with gear, this gear and the engagement of described tooth bar, the front end of described inner arm also is provided with runner, is wound with the slippage drag-line between this runner and the described gear, and described spinner pincers back-up block is connected on this slippage drag-line.

The structure that adopts above-mentioned telescopic arm can be adjusted the elongation and the shortening of the relative outer arm of inner arm by the control telescopic oil cylinder, thereby to drive the spinner pincers assembly back-up block moving range that can improve spinner pincers assembly back-up block so greatly of sliding by the slippage drag-line in inner arm be the moving range that spinner clamps assembly rotating on the tooth bar at elongation and the process of shortening middle gear simultaneously.

By the contrast of Fig. 1 and Fig. 4 as can be seen, the effect of spinner pincers back-up block by the slippage slot opened on inner arm, the outer arm and rack-and-pinion being withdrawn in the outer arm almost completely among Fig. 4, and the more close column of spinner pincers on the spinner pincers back-up block, entire equipment is compacter, the space that occupies is littler, for more space has been reserved in the operation of other equipment, flexible simultaneously more stable.

Described telescopic arm one end is provided with installing plate, and this installing plate is fixedly connected with rotating shaft, is connected with rotational fuel tank in this rotating shaft.

The setting of telescopic arm upper mounting plate and rotating shaft is for making by rotating shaft and being connected of column reaching the purpose that telescopic arm can be swung, satisfying the needs that clamping part clamping direction is adjusted in the mechanism that unloads.

Beneficial effect: by telescopic arm is designed cleverly, realized that flexible scope is bigger, especially in withdrawal more near column, total compacter be the enough spaces of operation reservation of other equipment.
