Example Embodiment

[0016] Example 1: Refer to the attached figure 1 , image 3 with Figure 4 , The lower end of the ramp 8 of the uphole operation pipe string conveying device of the present invention is connected to the catwalk support 9, the catwalk body 5 is above the catwalk support 9, and the upper end of the catwalk body 5 is horizontally provided with a V-shaped slide 11, The drill block 4 can slide in the V-shaped slide 11. A lifting support leg 6 and a sliding support leg 3 are connected between the catwalk body 5 and the catwalk support 9. Both ends of the lifting support leg 6 are hinged with the catwalk support 9 and the catwalk body 5 respectively, and the lifting support leg 6 and the sliding support leg 3 are hinged in an X shape at their respective midpoint positions. One end of the sliding support leg 3 slides in the lower rail 7, and the other end of the sliding support leg 3 slides in the upper rail 2 and is connected to the horizontal hydraulic cylinder 10. A guide conveyor...

Example Embodiment

[0020] Example 2: Reference figure 2 On the basis of the structure of the pipe string conveying device for uphole operations in Example 1, one end of the sliding support leg 3 close to the catwalk body 5 is a telescopic arm with a built-in hydraulic cylinder.

[0021] The process of uploading the pipe string: First, the catwalk body 5 is at the initial position, and the pipe conveyor belt 12 transfers the pipe string on the pipe rack to the V-shaped slide 11, and the drill carriage 4 moves to the pipe string along the V-shaped slide And against one end of the pipe string. Then the telescopic arm of the sliding support leg 3 is extended, so that the end of the catwalk body 5 close to the drill floor is tilted, and the catwalk body 5 is in an inclined state. The horizontal hydraulic cylinder 10 works, and the catwalk body 5 starts to lift. When the end of the catwalk body 5 close to the drill floor rises to the top of the drill floor and approaches the wellhead, the lifting stops....

Abstract

The invention relates to an overground operating string delivery mechanism for lifting a drill pipe, an oil pipe and the like of an overground operating platform. The overground operating string delivery mechanism comprises a catwalk body and a bit feeding pulley; the catwalk body is provided with a V-shaped slideway; the bit feeding pulley is arranged on the catwalk body and slides along the V-shaped slideway; a folding lifting support system is arranged below the catwalk body; the bit feeding pulley is provided with a driving mechanism; 1 to 4 slots are formed on the catwalk body at intervals; a conveyor belt system is arranged in the slots; the conveyor belt system and the V-shaped slideway are arranged in horizontal and perpendicular directions; two ends of the conveyor belt system extend outwards from two sides of the catwalk body; the conveyor belt system is linked with a lifting cylinder fixed to the catwalk body. The delivery mechanism lifts a string on a pipe rack to a drill floor in a mechanical mode, the degree of automation of drilling rig operation is increased, the labor intensity and the labor cost are reduced, and the safety is improved. The overground operating string delivery mechanism can be widely applied to automation renovation in the fields of oil rigs and workover rigs.

Description

technical field [0001] The invention relates to the field of supporting machinery for uphole operations, in particular to a delivery device for pipe strings such as lifting and landing drill pipes and oil pipes on an uphole operation platform. Background technique [0002] At present, in the operation process of conventional up-and-down drill pipes and tubing strings on land, it mainly relies on manpower plus a crowbar or forklift to push the strings on the pipe racks on both sides to the catwalk, tie a steel wire rope to one end of the string, and then One end of the pipe string is lifted by the pneumatic or hydraulic winch on the working machine and lifted to the working platform along the slideway. When the pipe string is lowered from the working platform, one end of the pipe string is lifted with a winch and a wire rope and lowered to the catwalk along the slide by the gravity of the pipe string. In the process of moving from the pipe rack to the catwalk, it is necessar...
