Manipulator for drill floor

Abstract

The invention discloses a manipulator for a drill floor. A horizontal moving guide rail is fixedly connected with the surface of the drill floor, a rotary bearing is installed on the horizontal movingguide rail, and a vertically arranged vertical moving guide rail is connected with the rotary bearing. A moving slide block is installed in the vertical moving guide rail, and the vertical moving guide rail and the moving slide block are correspondingly and fixedly connected to the fixed end and the movable end of a first oil cylinder. The moving slide block is hinged to the bottom of an inn moving arm, and the fixed end and the movable end of a second oil cylinder are correspondingly hinged to the middle and low parts of the moving slide block and the inner moving arm. The top of the inner moving arm is hinged to the top of the upper part of a moving arm, the fixed end of a third oil cylinder is hinged to the upper part of the inner moving arm, and the movable end of the third oil cylinder is hinged to the middle of the upper part of the moving arm. The manipulator can realize the automation of main work such as the movement of a pipe column of the surface of the drill floor, the buffering when the pipe column enters the drill floor to reach a wellhead and the rattling of the pipe column (drill pipe), and the problems that the current movement of the pipe column of the drill floor depends on manpower and multiple devices to work dispersedly are solved.

Description

technical field

[0001] The invention belongs to the technical field of oil and gas engineering drilling equipment, and in particular relates to a drill floor manipulator capable of realizing the displacement of a pipe string on the drill floor surface and the lowering of a drill pipe (into a mouse hole) during oil and gas exploitation. Background technique

[0002] Nowadays, in the field of drilling equipment for oil and gas exploration, with the continuous improvement of safety requirements and the increase of personnel costs, there are more and more demands for multifunctional manipulators on the drill floor, which are fully automatic, high efficiency, low energy consumption, remote control, It is an inevitable development trend to replace manual multi-functional manipulators for drill floor strings.

[0003] However, the existing pipe string movement on the drill floor is mainly driven by manpower, and the drill pipe entering the rat hole is mainly lifted by a pneumatic w...
