Intelligent full-hydraulic power catwalk

Abstract

The invention discloses an intelligent full-hydraulic power catwalk which comprises a supporting arm, a lifting leg, a pulley, a drill rod positioning mechanism, a plurality of active outriggers, a twisting machine, a twisting machine sliding rail, a control box, a ramp, outriggers, an overturning plate, a foundation support, a waterpower decoring device and a hydraulic station. The ramp is connected with the foundation support via a bolt, the twisting machine and the twisting machine sliding rail are mounted on one side of the foundation support, the waterpower decoring device is mounted on the twisting machine, the drill rod positioning mechanism and the overturning plate are arranged on the foundation support, the pulley is arranged on the supporting arm, the active outriggers are arranged on two sides of the foundation support, the hydraulic station supplies power to a system, and operation of the system is control by the control box. By the aid of the intelligent full-hydraulic power catwalk, processes including joint and throw rod connecting, hole bottom power connecting and disconnecting and water power rock coring can be integrated, twisting and water power decoring can be automatically finished without removal of a drill rod, technical requirements for drilling deep well coring are met, construction fields are greatly reduced, labor intensity is lowered, and working efficiency of a drilling system is improved. Since the power catwalk is fully hydraulically controlled, stepless speed change can be realized, transmission mechanism is simplified, and adaptability and reliability of the power catwalk are improved.

Description

Technical field [0001] The invention relates to a device for oil drilling and deep drilling, in particular to a fully hydraulic intelligent power catwalk matched with a drilling rig. Background technique [0002] At present, the degree of automation of oil drilling equipment at home and abroad is relatively weak, and cannot be adapted to the current level of development of drilling rigs. In addition, the catwalk plays a pivotal role in many equipment. The stability, mechanization and intelligence of the catwalk system directly determine the efficiency and safety of drilling. [0003] When the catwalks at home and abroad are connected to the second deck from the ground, the wire rope winch system is used to pull the stand to the second deck. This method has a relatively long running time, low efficiency, and high labor intensity and safety. Low sex. [0004] At present, catwalks at home and abroad can only complete the functions of sending single rods and throwing rods, and cannot r...

AI Technical Summary

Problems solved by technology

[0003] Domestic and foreign catwalks use a wire rope winch system to pull the stand to the second-floor platform when connecting a single root from the ground to the second-floor platform. This method takes a long time to run and has low efficiency. Low sex

[0004] At present, catwalks at home and abroad can only complete the functions of sending single rods and throwing rods, but cannot realize the functions of power connection and coring at the bottom of the hole, and cannot make the whole process systematized and intelligent, and the obtained cores are incomplete, reducing the Work efficiency, long work cycle, low degree of intelligence
