Abstract
The utility model discloses a tongs balancing system of tubular column tongs for oil field well drilling. Both sides of the front end of a telescopic boom are respectively provided with a spring placement hole; springs are arranged in the spring placement holes; the upper ends of the springs are provided with mandrils; the mandrils are pushed on the cross slab of the telescopic boom; the lower ends of the spring placement holes are provided with permanent seats; and puller bolts are spirally matched in the permanent seats. In the utility model, the front end of the telescopic boom is provided with the springs to keep the balance of both sides of tongs, and the pre-tightening forces of the springs can be controlled through regulating the puller bolts. The utility model has reasonable structural design and convenience in manufacturing.
Description
Technical field
The utility model relates to oil field welldrilling tubing string tonger, specifically belongs to a kind of working clamp balance sysmte 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 working clamp balance sysmte of oil field welldrilling tubing string tonger, the telescopic arm front end is respectively equipped with two lateral balances that spring keeps working clamp, can hold out against the pretightning force of screw control spring by adjustment, reasonable in design, easy to make.
The technical solution of the utility model is as follows:
A kind of working clamp balance sysmte of oil field welldrilling tubing string tonger, have the spring putting hole in telescopic arm front end both sides, be equipped with spring in the spring putting hole, the upper ends of spring has push rod, the push rod overhead is on the transverse slat of telescopic arm, the lower end of spring putting hole is provided with holder, and spiral is combined with and holds out against screw in the holder.
Described holding out against screwed togather locking nut on the screw, the lower surface of compacting of locking nut upper end and holder.
The utility model is respectively equipped with two lateral balances that spring keeps working clamp at the telescopic arm front end, can hold out against the pretightning force of screw control spring by adjustment, and reasonable in design is easy to make.
