Drilling rod structure with retractable protective cover

Abstract

The invention relates to a drilling rod structure with a retractable protective cover. The drilling rod structure comprises drilling rods and a drilling rod blades arranged on the drilling rods, wherein the drilling rods are arranged at the lower end of a drilling machine connecting part; the retractable protective cover for preventing splashing is arranged at the outer parts of the drilling rods;the protective cover is composed of a plurality of foldable cover body units; a sleeve ring is arranged between each two adjacent cover body units; each sleeve ring is connected with a hoisting and traction unit; the hoisting and traction units are used for pulling the sleeve rings to control the protective cover to be retracted and folded. According to the drilling rod structure with the retractable protective cover, provided by the invention, the problem that a protective cover needs to be continuously, lengthened in a working process of a drilling machine, so that the construction efficiency is influenced is solved, and the problem that mud is splashed to injure people when the drilling rods rotate can be solved; the drilling rod structure is mounted on each type of drilling machine ina specific utilization process and is matched with a drilling tool; the height of the retractable protective cover is adjusted through controlling a retractable windlass, so that the labor cost is reduced; the drilling rod structure is simple to operate and strong in safety.

Description

technical field [0001] The invention relates to the technical field of drilling rigs, in particular to a drill rod structure with a retractable protective cover. Background technique [0002] A drilling rig is a complex set of machines, which consists of machines, units and mechanisms. Drilling rig is a mechanical device that drives drilling tools to drill underground to obtain physical geological data during exploration or development of mineral resources (including solid ore, liquid ore, gas ore, etc.). The rock at the bottom of the hole, the drilling tool that is lowered or raised in the hole, can be used to drill cores, ore cores, cuttings, gas samples, liquid samples, etc., to prove the underground geology and mineral resources. [0003] The protective cover is a protective tool used to prevent mud from splashing and hurting people when the drill pipe is working and rotating. It is used in conjunction with the drilling rig. When the drilling rig is working, the protect...

AI Technical Summary

Problems solved by technology

[0004] The protective cover on the grouting drilling rig used in the market is composed of simple steel plate splicing, which is large in size and heavy in weight. It needs to be extended during use, which consumes manpower and material resources. It is inconvenient and unsafe to operate, which affects construction efficiency.
