Abstract

The invention belongs to the technical field of petroleum equipment, and particularly relates to a drilling tool supporting mechanism. The drilling tool supporting mechanism comprises a first grabbing rod, a second grabbing rod and a transmission mechanism, the transmission mechanism can drive the first grabbing rod and the second grabbing rod to move in the opposite directions or in the contrary directions, a first finger assembly is arranged at the end, away from the transmission mechanism, of the first grabbing rod, the first finger assembly comprises a first driving device and a first stop lever, and the first driving device can drive the first stop lever to get close to or away from the transmission mechanism; a second finger assembly is arranged at the end, away from the transmission mechanism, of the second grabbing rod, the second finger assembly comprises a second driving device and a second stop lever, and the second driving device can drive the second stop lever to be close to or away from the transmission mechanism; and the first stop lever, the second stop lever and the transmission mechanism jointly form a supporting space used for supporting a target drilling tool. The target drilling tool can be supported in all directions, so that the probability that the target drilling tool falls off can be reduced, and the working reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of petroleum equipment, and in particular relates to a drilling tool supporting mechanism. Background technique [0002] Wellhead automation and unmanned are the development direction of petroleum equipment, and automatic pipe arrangement device is a major wellhead automation equipment. The automatic pipe arrangement generally includes a pulley mechanism, a mechanical arm and a drill support mechanism. The pulley mechanism is installed on the drill floor, and the bottom of the mechanical arm is set on the pulley mechanism; the drill support mechanism is hinged at the end of the mechanical arm. When it is necessary to move the drilling tool, the pulley mechanism works to drive the mechanical arm and the drilling tool supporting mechanism to the position of the drilling tool; then the mechanical arm unfolds, drives the drilling tool supporting mechanism to approach and support the drilling tool, and finally dr...
