Hydraulic holding hook short-connection assembly for engineering drilling machine

Abstract

The invention discloses a hydraulic holding hook short-connection assembly for an engineering drilling machine. The problems that in the prior art, when an engineering drilling machine works, a drill rod and a drilling tool are inconvenient to splice, and time and labor are consumed are solved. The hydraulic holding hook short-connection assembly comprises a hydraulic holding hook pipe seat, a rotating device, a lifting device, a drill rod holding seat and a holding device. By means of the hydraulic holding hook short-connection assembly, automatic splicing can be achieved when the drill rod is spliced for the engineering drilling machine, the splicing efficiency is improved, and the time cost is saved; the center position of a lower side connector can be adjusted through an upper flange, then the center position of the drill rod is adjusted, and the center position of the drill rod and the center position of the drilling tool are located on the same perpendicular line; the rotating device and the lifting device are arranged, the lower end of the drill rod can be spliced to the drilling tool or separated from the drilling tool through the rotating device and the lifting device, and automatic splicing or disassembling of the drill rod and the drilling tool is achieved; and meanwhile, the drill rod holding seat is arranged and used for locking or unlocking a holding rod, and the holding rod is prevented from falling in the splicing process.

Description

technical field [0001] The invention relates to the technical field of drilling rigs, in particular to a hydraulic hook shorting assembly for engineering drilling rigs. Background technique [0002] Engineering drilling rigs are widely used in geological exploration, engineering construction, mines, wind energy, hydropower construction, and environmental protection. Drilling rigs are mechanical equipment that drive drilling tools to drill underground to obtain physical geological rock and soil. Drill a kilometer deep hole.

AI Technical Summary

Problems solved by technology

In the process of drilling deep holes, the drilling tool often needs to be lifted and released several times to check its wear condition. The traditional operation method of lifting and releasing the drilling tool must be realized by repeatedly fixing and connecting the upper end of the drill pipe, and it is necessary to use a manipulator to drive the drill pipe. When clamping the drilling tool, since the drilling tool and the drill pipe are mostly connected by rigid positioning, the manipulator is required to control the rotation of the drill pipe at a certain angle. However, when the drill pipe and the drilling tool are spliced, the center of the drill pipe must be aligned with the center of the drilling tool. This requires a high degree of proficiency of the operator and multiple attempts to splice the drill pipe to the drill tool, which consumes a lot of time and cost, and is not easy to use
