Description
Technical field
The utility model relates to a kind of device for the slip in oil and gas well drilling operation.
Background technology
The instrument holding drilling rod in existing oil, natural gas operations is mainly manual drill pipe slip, and it is multiple-piece structure, and volume is large, weight is large, and tile wherein causes wearing and tearing because service time is long, needs often to change tile, labor strength is large, inefficiency and safety is not high.
Summary of the invention
In order to solve the large and deficiency that safety is not high of existing drill rod grip device inefficiency, labor strength, the utility model provides a kind of drill rod grip device.
The utility model solves the technical scheme that its technical problem adopts: in drill rod grip device housing, at least four symmetry directions are provided with hydraulic cylinder, described hydraulic cylinder is fixed in housing, described hydraulic cylinder is at least provided with two on each azimuth axis direction, the line correspondence bearing that the piston rod of described hydraulic cylinder is provided with by annulus fixed frame is connected with holder, described piston rod and linear bearing are slidably matched, described linear bearing is installed on annulus fixed frame, described holder is partial circle column, described holder inside is provided with oblique ridge for inside annular, described oblique ridge is provided with ball, described ball is stressed and can shrinks inside oblique ridge and can roll, described housing and annulus fixed frame fix correspondence position by lower shoe and top panel, circular hole is provided with in the middle of described top panel and lower shoe, hydraulic controller is provided with outside described housing, described hydraulic controller is connected with hydraulic cylinder.
The piston rod of hydraulic controller hydraulic control cylinder does expanding-contracting action, hydraulic cylinder not easily compresses due to its internal hydraulic pressure oil, make its when stressed large can not move, the piston rod of hydraulic cylinder coordinates with linear bearing, piston rod is made to drive holder slide steadily and can not move, the ball that ridge on holder is provided with can make the thread on itself and oil drill rocker closely cooperate, and can freely roll wherein due to ball, coordinate so it rolls with the thread on drilling rod, reduce its wearing and tearing.
The beneficial effects of the utility model are: the utility model is rational in infrastructure, can hold plurality of specifications oil drill rocker, and device for clamping wearing and tearing are little, safeguard simple.
