Abstract
The invention aims to provide a pipe clamping jaw device in drilling wellhead operation, and particularly relates to an oil drilling pipe clamping jaw. The device can be mounted on a working platform so as to achieve automatic spatial discharging of vertical drill rods, the device can also be mounted at a drilling operation site to be used for transporting and moving various sorts of pipes, and the device is suitable for other occasions where the pipes need to be discharged as well. By means of the oil drilling pipe clamping jaw, the labor intensity of workers is lowered, working efficiency is improved, and potential safety hazards are eliminated. When the pipes are clamped, the pipe clamping jaw is adjusted to be in the appropriate posture, jaws can grab and compress the pipes automatically, and then the pipes are moved and discharged. The jaws and pressure levers are both of a contra-parallelogram structure, a driving hydraulic cylinder is omitted, and each pair of paws and pressure levers can operate synchronously.

Described pipe jaw comprises paw I, depression bar I, oscillating cylinder, connecting rod I, hydraulic cylinder II, hydraulic cylinder III, depression bar II, connecting rod II, axle I, axle II, axle III, bearing III, fixed head, paw II, axle IV, bearing IV, axle bed I, axle bed II.Wherein oscillating cylinder is arranged on fixed head, and is connected with wrist mechanism.The rotation of whole jaw can be realized.Fixed head is hinged respectively for paw I and paw II, the paw I other end is connected with paw II by connecting rod I thus is formed anti-parallelogram mechanism, hydraulic cylinder III one end is connected with axle I with bearing IV one end, axle I is connected with paw II, can drive the opening and closing of paw I and paw II when hydraulic cylinder III stretches simultaneously.Depression bar I, depression bar II and connecting rod II also form anti-quadrangular mechanism, and when clamping pipe, paw I and paw II catches pipe, and pipe is pushed down by depression bar I and depression bar II again, thus realizes the firm grip of pipe.
Described wrist mechanism comprises wrist, bearing I, hydraulic cylinder I, bearing II.Wrist one end is connected with oscillating cylinder, one end and forearm hinged.Stretching thus the attitude of adjustment wrist by hydraulic cylinder I, and then the position of adjustment clamping device.
Described arm comprises principal arm, forearm, compensating cylinder, end cap I, end cap II, motor II, motor II I.Driven the rotation of principal arm and forearm by motor II, motor II I respectively, thus realize stretching, extension and the contraction of jaw arm.Compensating cylinder one end is connected one end with principal arm and is connected with pedestal.
Described supporting mechanism is made up of pedestal and motor I.Pedestal includes revolving support, is driven the revolution that can realize jaw by motor I.
