Integrated rotary upright catwalk

Abstract

The invention discloses an integrated rotary upright catwalk which comprises a fixedly arranged main frame body, a rotary upright catwalk main body and a power mechanism. One end of the rotary upright catwalk main body is coupled with a hinge mechanism, and the rotary upright catwalk main body can rotate around the hinge mechanism; and a power steel cable connected with the power mechanism is connected with the other end of the rotary upright catwalk main body through a roller and can drive the rotary upright catwalk main body to switch between the horizontal movement and the vertical movement. The drilling catwalk is high in automation degree, high in transmission efficiency, safe, reliable and more reasonable in stress, the service life of the drilling catwalk is greatly prolonged, and the transportation efficiency is improved. A plurality of drilling tools can be simultaneously conveyed through the rotary upright catwalk, the conveying efficiency is improved, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to an intelligent drilling platform, in particular to an integrated rotating upright catwalk. Background technique [0002] Drilling catwalk is a kind of pipe conveying equipment, which can safely and reliably transport pipes back and forth between the drilling platform and the ground. It has the characteristics of high reliability, strong adaptability, high conveying efficiency and safety, and is very important in drilling equipment. A pipe transportation equipment. [0003] Existing drilling catwalks mainly contain the following three types: 1. Power cable-driven power catwalks rely on power cables and winches to pull the trolleys on the catwalks, and the trolleys pull the drill pipes. The steps of the pipe collar are under force to drive the pipe. The early products only have the function of lowering the pipe, but not the function of the upper pipe.

Problems solved by technology

[0003] Existing drilling catwalks mainly contain the following three types: 1. Power cable-driven power catwalks rely on power cables and winches to pull the trolleys on the catwalks, and the trolleys pull the drill pipes. The steps of the pipe collar are under force to drive the pipe. The early products only have the function of lowering the pipe, but not the function of the upper pipe. The main defects of this kind of drilling catwalk are: the drill pipe and drill collar casing can only be sent to the ramp, not to the drill floor The position of the upper wellhead requires secondary hoisting; when the drill pipe and drill collar casing need to be lowered to the drill floor, the pipe also needs to be hoisted to the ramp of the drill floor gate before the pipe can be lowered. One more process reduces the safety and does not It meets the requirements of automatic drilling technology; the hydraulic pipeline on the trolley needs to be continuously extended and contracted with the movement of the trolley, so being stretched reduces the service life and reliability

[0004] 2. The four-link type power catwalk, through the hydraulic cylinder to push the support rod, the pipe delivery beam is lifted until the drill floor, and the hydraulic cylinder or trolley on the beam pushes the transported pipe to the wellhead. The main defects of this drilling catwalk are: : When the drill pipe drill collar casing needs to be lowered to the drill floor, the pipe head must be pulled to the beam before the pipe can be lowered, which does not meet the requirements of automatic drilling technology; Poor stability when the beam is lifted in the air

[0005] 3. Power cable ramp pull-up type power catwalk, one end of the beam is supported by the link rod, the other end is supported by the ramp of the drill floor gate and the roller on the beam, and at the same time, it is connected to the middle of the beam by pulling two power cables through the hoist The lug plate at the position drives the beam to rise, and the beam can reach the position about 500mm from the center of the wellhead on the drilling floor, and the pipe is directly sent to the wellhead. When the pipe is lowered, the pipe head can be conveniently placed in the V-shaped groove of the beam, and the beam descends On the catwalk, its main disadvantages are: the hoist configuration has a large power and high energy consumption; the power cable is easy to wear and is easily damaged during the disassembly process; the power cable is used in a certain section many times, and it is difficult to quantitatively determine the wear when replacing degree, the reliability decreases
