Embodiment Construction

[0043] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following describes the present invention through specific embodiments shown in the drawings. However, it should be understood that these descriptions are only exemplary, and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0044] This embodiment will be described with reference to the drawings, see figure 1 , figure 2 , The power catwalk of the oil drilling rig of the present invention includes a first base 1, a lifting mechanism 2, a conveying mechanism 3, a control box 4, and a hydraulic pump station 5.

[0045] The first base 1 is a truss structure and is welded by profiles. The first base can be divided into two parts according to functions: a front end load-bearing area,...

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 power catwalk of an oil drilling rig and a drilling tool loading method thereof. Background technique [0002] The catwalk is an important part of the pipe string discharge system of the drilling rig. It belongs to the transportation part. Through the corresponding operation, the drill pipe, drill collar and other tools used for drilling can be transported to the drilling platform to complete the corresponding drilling process operation. Its structure layout The rationality and operability directly affect the speed, efficiency, stability, safety and reliability of drilling operations. In traditional drilling operations, onshore and offshore drilling rigs mostly use conventional matching ramps and catwalk combinations. The small drawworks on the drill floor and the small drawworks on the catwalk are used to coordinate the drilling tools on the pipe racks. Lift to the ...
