Abstract
The utility model discloses a rotary grip of a pipe column clamp for oil field drilling, which comprises a rotary grip box body. The rotary grip box body is hanged on an independent bracket through four screws respectively sleeved with a spring, a clamping cylinder is arranged in the rotary grip box body and is connected with a rotary clamping roller, and the rotary clamping roller is driven by a hydraulic motor. Since the rotary grip box body can move freely within a corresponding range on the independent bracket, the utility model has the advantages that the rotary grip can adapt to pipe columns with different position requirements, can stably clamp the rotating pipe columns and ensure the precision of connection of the pipe columns.
Description
Technical field
The utility model relates to oil field welldrilling tubing string tonger, specifically belongs to a kind of spinner pincers of oil field welldrilling tubing string tonger.
Background technology
Oil well pipe can be divided into two big classes on function, a class is an oil casing, and another kind of is drill string.Oil casing mainly comprises sleeve pipe, oil pipe and annex.Drill string mainly comprises drilling rod, drill collar, kelly bar and member thereof (tool joint, crossover sub and pipe nipple etc.).Modern petroleum industry technology merges the part of functions of two classes, as casing drilling tubing string, operation and drilling well coiled tubing post.
The utility model content
The purpose of this utility model provides a kind of spinner pincers of oil field welldrilling tubing string tonger, spinner pincers casing can possess corresponding limited free displacement on independent rack, adapt to the tubing string that diverse location requires, the tubing string of rotation clamps stable, has guaranteed the precision size that connects between the tubing string.
The technical solution of the utility model is as follows:
A kind of spinner pincers of oil field welldrilling tubing string tonger, include spinner pincers casing, spinner pincers casing hangs on the independent rack by four screw rods that are set with spring, in the spinner pincers casing clamping cylinder is installed, clamping cylinder is connected with and revolves nip rolls, revolves nip rolls by the hydraulic motor transmission.
Be fixed with installing plate on the described independent rack, have installing hole on the installing plate, screw rod passes installing hole, leaves the space between installing hole and the screw rod.
Described clamping cylinder is externally connected with synchronous valve.
Spinner pincers casing of the present utility model can possess corresponding limited free displacement on independent rack, adapt to the tubing string that diverse location requires, and the tubing string of rotation clamps stable, has guaranteed the precision size that connects between the tubing string.
