Abstract

The invention discloses a novel oil drilling machine power catwalk and drilling tool loading method thereof. The novel oil drilling machine power catwalk comprises a first base, a hoisting mechanism, a conveying mechanism, a control box and a hydraulic pumping station; the conveying mechanism comprises a conveying rack, a jacking hydraulic cylinder, swing motor assemblies, a cart, a cart drive mechanism, a loading and unloading mechanism; the first base and the conveying mechanism are correspondingly hinged to the two ends of the hoisting mechanism through pin rolls; and the hoisting mechanism and the conveying mechanism are electrically connected with the control box correspondingly. According to the novel oil drilling machine power catwalk, the power catwalk is compact in structure, simple in operation, high in efficiency, fast in installation, high in system stability; the jacking hydraulic cylinder matches with the swing motor assemblies on the two sides of the jacking hydraulic cylinder for work; a layered mechanism of the power catwalk is constituted jointly by the jacking hydraulic cylinder and the swing motor assemblies together constitute the power of the cat body of the layered body; a plurality of commonly used sizes of drilling tolls on the conveying rack can be transmitted at one time; the drilling tools are pushed at a high position in sequence, the transmission efficiency of the drilling tools is improved; and a transmission cost is reduced.

Description

technical field [0001] The invention relates to the technical field of oil drilling equipment, in particular to a novel oil drilling rig power catwalk and a drilling tool loading method thereof. Background technique [0002] The catwalk is an important part of the drilling rig string drainage system, which belongs to the conveying part. Through corresponding operations, the drill pipes, drill collars and other tools used for drilling can be transported to the drilling platform to complete the corresponding drilling process operations. Its structural layout The rationality and operability of drilling directly affect the speed, efficiency, stability, safety and reliability of drilling operations. In traditional drilling operations, onshore and offshore drilling rigs mostly use a combination of conventional matching ramps and catwalks, mainly relying on the cooperation of the small drawworks on the drill floor and the small drawworks on the catwalk to move the drilling tools on...
