Embodiment Construction

[0015] refer to figure 1 , figure 2 . Motor I (11) is installed on the pedestal (1), and pedestal (1) contains slewing bearing, when motor I (11) work, can drive whole jaw device to do horizontal plane rotary motion. One end of the balance cylinder (2) is connected to the base (1), and one end is connected to the main arm (4). The main arm (4) is installed on the base (1) and driven by the motor II (12), so that the main arm ( 4) It can move vertically within a certain range. One end of the small arm (30) is connected to the main arm (4) and driven by the motor III (13), so that the small arm (30) can move around the main arm (4). swing within a certain range. The other end of the forearm (30) is connected with the wrist (9), the support I (6) is installed on the forearm (30), the support II (8) is installed on the wrist (9), and the hydraulic cylinder I (7 ) is connected to the support I (6) at one end, and connected to the support II (8) at the other end. When the hydra...

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.

Description

technical field [0001] The invention relates to a clamping jaw of an oil drilling pipe tool, which belongs to the technical field of oil drilling wellhead equipment. Background technique [0002] In oil drilling, the movement and discharge of various pipes is an important part of drilling operations. In the traditional drilling operation, the clamping of the pipe string needs to be completed manually, which has high labor intensity, low work efficiency and poor safety. Contents of the invention [0003] The object of the present invention is to provide a pipe gripper device in drilling operations, which can be installed on the working platform to realize the automatic clamping, transportation and discharge of drill pipes in space, and can also complete various pipe gripping at the drilling site. Automatic transportation and movement are also applicable to other occasions that require discharge pipes. The invention reduces labor intensity, improves work efficiency and imp...
