Moving swing pipe clamping mechanism

Abstract

The invention relates to a moving swing pipe clamping mechanism and belongs to the technical field of drilling machine equipment. The mechanism comprises a main arm and a teleflex installed on the main arm in a sliding mode, wherein the upper end of the teleflex is connected with a first hydro-cylinder through bolts, the lower end of the teleflex is connected with a chuck through outer screw threads, a top plug is installed in the teleflex in a sliding mode, the upper end of the top plug is connected with a piston rod which is located at the front end of the first hydro-cylinder and the lower end of the top plug penetrates into the chuck. The lower end of the main arm is connected with a limit gland through the bolts, a limit cover is nested into the limit gland, a spacer pin is installed inside the limit cover, the spacer pin penetrates through the teleflex and the top plug, and the teleflex and the top plug are connected into an integrated structure. The lower end of the chuck is connected with a hydro-cylinder support, and the hydro-cylinder support is connected with a second hydro-cylinder through the bolts. The mechanism is simple, compact and reasonable in structure, the hydraulic energy of the drilling machine is used as a driving force and lowers the cost, the chucking is safe and reliable when the drill pipe is lifted and the alignment is convenient after reaching the position, and the mechanism is convenient to maintain and simple in maintenance and flexible and reliable in movement due to little restriction between parts.

Description

technical field [0001] The invention relates to a clamping mechanism for a swing pipe, which belongs to the technical field of drilling rig equipment. Background technique [0002] A drilling rig is a mechanical device that drives a drilling tool to drill underground to obtain physical geological data in geological exploration. Also known as drilling machine. The main function is to drive the drilling tool to break the rock at the bottom of the hole, and to lower or lift the drilling tool in the hole. It can be used to drill cores, ore cores, cuttings, gaseous samples, liquid samples, etc., to ascertain the conditions of underground geology and mineral resources. [0003] The general name of the entire drilling pipe string and its joints used in the drilling construction is called the drilling tool (. The drilling tool is composed of a driving drill pipe, a drill pipe, a core pipe, and a reamer and a drill bit at the bottom. A sedimentation pipe or drill collar is added t...

AI Technical Summary

Problems solved by technology

[0004] When the drilling rig is equipped with air reverse circulation double-wall drill pipe or large-diameter drill pipe, the labor intensity of the driller's handling and loading and unloading of the drill pipe is relatively high, which is time-consuming and labor-intensive.
