Abstract
The utility model discloses a novel air operated slip, which comprises a main body. An inner hole of the main body is conical, a slip component is arranged in the inner hole of the main body, is connected with a lifting mechanism and comprises a conical slip body matching with the conical inner hole of the main body, slip teeth for clamping a tubular column are disposed in the slip body, and a connecting rod connected with the lifting mechanism is arranged on the upper portion of the slip body. The novel air operated slip is reasonable in structure, large in lifting force, wide in application range and convenient in operation, and is safe and reliable.
Description
Technical field
The utility model relates to the power tool that removes drilling rod in a kind of oil, the Natural Gas Drilling Operation.
Background technology
Existing slips mostly is a manual slip, and operation is heavy, and the execute-in-place labor strength is big, and safety is not high.
Summary of the invention
The purpose of this utility model is to provide the novel pneumatic that a kind of mechanism is reasonable, easy to operate, lifting force is big, safe and reliable slips.
Technical solution of the present utility model is:
A kind of novel pneumatic slips is characterized in that: comprise main body, the main body endoporus is tapered, in the main body endoporus slip assemblies is set, and slip assemblies is connected with hoisting mechanism; Described slip assemblies comprises the taper slips body that cooperates with the main body cone-shaped inner hole, and the slip insert that holds tubing string is set in the slips body, and slips body top is provided with the connecting rod that is connected with hoisting mechanism.
The slips body is the form of leafy composition, and every leaf of slips body is connected with hoisting mechanism by a connecting rod respectively.
Two leaves about the slips main body has, two leaves link into an integrated entity by junction plate and connecting pin that junction plate is connected with main body about main body.
The guide ring that drilling rod is play the guiding role is set in the slips lower body part.
Hoisting mechanism comprises the equalizer bar that is connected with the connecting rod of slip assemblies, and equalizer bar is connected with the piston rod of cylinder, and equalizer bar is connected with guide rod in being contained in the slips main body.
The utility model is rational in infrastructure, lifting force is big, applied widely, in drilling well round trip process, can realize Long-distance Control, in driller house, can control lifting, the decline of slips by control crank, thereby the function that tubing string is unclamped, fastens in realization is easy to operate, safe and reliable, operating efficiency promotes significantly.But the lid anticollision can be loaded onto in top, and guide ring is equipped with in the bottom can guarantee drilling rod centering, and unsteady cleaning shoe can guarantee slips rig floor cleaning, and the slips back side can have been designed anti-the turning round with unexpected of boss and rotate.Gas circuit can design the protection of dying, and can prevent contingency, guarantees round trip safety.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
A kind of novel pneumatic slips comprises main body 1, and the main body endoporus is tapered, and slip assemblies 2 is set in the main body endoporus, and slip assemblies is connected with hoisting mechanism 3; Described slip assemblies comprises the taper slips body 201 that cooperates with the main body cone-shaped inner hole, and the slip insert 202 that holds tubing string is set in the slips body, and slips body top is provided with the connecting rod 203 that is connected with hoisting mechanism.
The slips body is the form of leafy composition, and every leaf of slips body is connected with hoisting mechanism by a connecting rod respectively.
Two leaves 101 about slips main body 1 has, two leaves link into an integrated entity by junction plate 102 and with the connecting pin 103 that junction plate is connected with main body about main body.The guide ring 104 that drilling rod is play the guiding role is set in the slips lower body part.
Hoisting mechanism 3 comprises the equalizer bar 301 that is connected with the connecting rod of slip assemblies, and equalizer bar is connected with the piston rod of cylinder 302, and equalizer bar is connected with guide rod 303 in being contained in the slips main body.
During work, cylinder piston rod motion drives equalizer bar and moves up and down, and equalizer bar drives guide rod again and moves up and down, and move up and down drivening rod and slips body of equalizer bar moves up and down, thereby realizing that slips rises unclamps tubing string, and descending holds the function of tubing string.
