Abstract

The invention relates to a drilling rod hoist for an oil drilling rig and a drilling tool loading method thereof. Frame, roller, long connecting rod, clamping cylinder, clamping pliers, clamp connecting frame, supporting pliers, supporting cylinder, luffing cylinder, rocker, short connecting rod, tilting cylinder; the wire rope is driven by the winch to bypass The pulley assembly is connected with the block assembly unit module and drives it to slide up and down in the gantry assembly. In the present invention, the clamping tongs, supporting tongs, luffing cylinders, tilting cylinders and hydraulic drawworks cooperate with each other to realize the drilling tool from the catwalk to the wellhead, from the catwalk to the magazine, from the wellhead to the catwalk, and from the magazine to the catwalk , Automatic delivery from the wellhead to the clip, and from the clip to the wellhead, and realizes the offline operation of connecting the drill pipe, improves the delivery efficiency of the drilling tool, saves the delivery cost of the drilling tool, and has fewer failures and high efficiency in the production process.

Description

technical field [0001] The invention relates to the technical field of oil drilling equipment, in particular to an oil drilling rig drill pipe hoist and a drilling tool loading method thereof. Background technique [0002] The drill pipe hoist is an important part of the drilling rig string discharge system. The drill pipe hoist is a device used for lifting, lowering and conveying the drill pipe. It belongs to the conveying part. Tools such as collars are transported from the catwalk to the wellhead or magazine, the wellhead or the magazine to the catwalk, the wellhead to the magazine, and the magazine to the wellhead to complete the corresponding drilling tool delivery operation. The rationality and operability of its structural layout directly affect The speed, efficiency, stability, safety and reliability of drilling operations. In traditional drilling operations, land drilling rigs mostly use a combination of conventional catwalks and drill floor tools, mainly manually ...
