Abstract

The invention relates to a racking platform bent arm pushing type drill rod discharging mechanical arm which comprises a track beam, a bottom chain, a sliding trolley, a power device, a sliding base, a small arm, a hydraulic clamp, a rotating rod, a hydraulic cylinder and a bent arm. A sliding way is arranged at an inner cavity of the track beam. Sliding wheels of the sliding trolley are connected to the sliding way of the inner cavity of the track beam in a clamping mode. The front end of the sliding base is fixedly connected to the sliding trolley through a screw. The power device is embedded to the inner cavity of the sliding base and is fixedly connected with the sliding base. The bottom chain is connected with the bottom of the track beam in a sliding mode. A gear of the power device is meshed with the bottom chain. The back end of the sliding base is in sliding connection with the front end of the bent arm through a pin shaft. One end of the hydraulic cylinder is in sliding connection with the back end of the sliding base through a pin shaft. The other end of the hydraulic cylinder is connected to the bent arm through a pin shaft. The bent arm is connected with a small arm through a pin shaft. The bottom of the small arm is provided with a swinging hydraulic cylinder. The other end of the swinging hydraulic cylinder is fixedly connected with the hydraulic clamp. The racking platform bent arm pushing type drill rod discharging mechanical arm is compact in structure, light in weight and high in reliability, working efficiency is improved, and labor intensity and potential safety hazards are lowered.

Description

technical field [0001] The invention relates to a drilling tool, in particular to a push-type drill pipe discharge manipulator with a curved arm on a two-story platform. Background technique [0002] Drill pipe discharge is a necessary process to move the drill pipe from the discharge rack to the wellhead or from the wellhead to the discharge rack during the drilling and tripping process. At present, the discharge of the pipe string (drill pipe, weighted rod and drill collar) in the drilling operation is usually The elevator is manually operated, and the elevator catches the collar of the drill pipe, and then the derrick worker holds the pipe wrench to contact the pipe string, and the operation efficiency is low. The make-up, break-out and discharge of the pipe string also need the cooperation of many workers, and the labor intensity is high. Due to the frequent contact between workers and the pipe string, and the need to perform high-altitude operations on the second floor...
