Abstract
The application provides a multifunctional guide column grabbing tool, which comprises a lifting ring, an operating handle, a hook claw operating handle, a rod body, an inner sleeve, a mandrel and a hook claw. The lifting ring is installed at the top end of the rod body. The operating handle is located at the upper end of the rod body and is used for adjusting the pose of the multifunctional guide column grabbing tool by an operator. The lower end positioning pin of the rod body is used for being inserted into the circular hole at the upper end of the long guide column rod body. The inner sleeve is located inside the rod body and is configured to slide up and down inside the rod body. The lower end of the inner sleeve is provided with a boss structure, and the upper end of the inner sleeve is provided with the hook claw operating handle. The mandrel is located inside the inner sleeve, the upper end of the mandrel is matched with a hand torque wrench, and the lower end of the mandrel is matched with a long guide column locking rod. The multifunctional guide column grabbing, transferring and screwing are integrated by the application, so as to solve the technical problems that the operation time of the operator is too long and the irradiation dose of the on-site operator is increased due to the complex operation of the guide column.
