Problems solved by technology

Most of the existing drilling platform piping systems are connected by iron drillers or power tongs during the docking process. Every time the docking is carried out, the drilling tool must be placed in the rat hole, and it is taken out from the rat hole after docking. The docking process In the process, it is necessary to manually correct the position of the drill pipe, which makes the whole docking process take a long time and work efficiency is low
In addition, it is time-consuming to transport the drill pipe stand after docking, and there is no special equipment at present

Embodiment 1

[0021] Such as figure 1 , image 3 and Figure 4 As shown, the automatic piping system of an offshore drilling platform includes a derrick 1, at least one set of pipe grabbing devices 2 for grabbing and discharging drill pipes 6, a hydraulic catwalk 3 matched with the pipe grabbing devices, and a pipe grabbing device associated with The matching mouse hole 4 and the PLC control device (not shown in the figure) controlling the overall system, the derrick 1 is fixed on the drilling platform 5, and the hydraulic catwalk 3 is used to transport the drill pipe 6 to the designated position, so as to facilitate the installation of the pipe grabbing device. Grabbing; the mouse hole 4 is fixed under the drilling platform to provide space for the docking of the drill pipe; the pipe grabbing device includes: a guide rail column 8 for fixing the mechanical arm 7, and an upper seat 9 connected to the top of the guide rail column 8 in a 360° rotatable manner 1. The lower seat 10 connected ...

Embodiment 2

[0039] Such as figure 2 As shown, two grasping hands 13 are provided on the rotary connection seat 25 of the upper mechanical arm, and a pipe grasping hand 13 and an upper and lower buckle device 14 are arranged on the rotary connection seat 25 of the lower mechanical arm. 1. The breaking and breaking device 14 is located above the lower pipe gripping hand 13, and a torque real-time monitoring and controlling device 15 is arranged on the upper and breaking breaking devices 14 at the same time.

[0040] Other structures of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0042] Such as Figure 5As shown, three grasping hands 13 are provided on the rotary connection seat 25 of the upper mechanical arm, and two pipe grasping hands 13 and an upper and lower buckle device 14 are arranged on the rotary connection seat 25 of the lower mechanical arm. 1. The breaking and breaking device 14 is located above the lower pipe gripping hand 13, and a torque real-time monitoring and controlling device 15 is arranged on the upper and breaking breaking devices 14 at the same time.

[0043] Other structures of this embodiment are the same as those of Embodiment 1.

Abstract

The invention discloses an automatic pipe arranging system for a marine drilling platform. The automatic pipe arranging system for the marine drilling platform comprises a derrick, at least one set of pipe grabber for grabbing and arranging drill pipes, a hydraulic catwalk, a mouse hole and a PLC (Programmable Logic Controller) control unit for controlling the whole system, wherein the derrick is fixed on the drilling platform, and the mouse hole is fixed below the drilling platform. The automatic pipe arranging system for the marine drilling platform is characterized in that a guide rail stand column is provided with an upper mechanical arm and a lower mechanical arm, the front ends the upper mechanical arm and the lower mechanical arm are both provided with a rotation type connecting base, the rotation type connecting base of the upper mechanical arm is at least provided with a pipe grabbing hand and a make-up and break-out device, and the rotation type connecting base of the lower mechanical arm is at least provided with a pipe grabbing hand. The automatic pipe arranging system for the marine drilling platform has the advantages of achieving the abutting joint of the drill pipes in the air and being capable of automatically adjusting the position of the upper drill pipe and the lower drill pipe during an abutting joint process, shortening abutting joint time, improving working efficiency and reducing construction cost.

Description

technical field [0001] The invention relates to a drilling construction equipment, in particular to an automatic piping system of an ocean drilling platform. Background technique [0002] During the drilling construction operation, it is a very important process to dock the stand of the drilling tools (drill pipe, drill collar, casing, etc.), and each stand needs to be docked twice. Most of the existing drilling platform piping systems are connected by iron drillers or power tongs during the docking process. Every time the docking is carried out, the drilling tool must be placed in the rat hole, and it is taken out from the rat hole after docking. The docking process In the process, it is necessary to manually correct the position of the drill pipe, which makes the whole docking process take a long time and work efficiency is low. In addition, it is time-consuming to convey the vertical roots of the drilling tools after docking, and there is no special equipment at present....
