Impact type multifunctional airborne drilling rig

Abstract

The invention belongs to the technical field of coal mine development machinery, is used for blasting drilling holes of a hard-rock rock roadway in an underground coal mine in construction and various drilling holes in the support work of anchor rods and anchor ropes, and provides an impact type multifunctional airborne drilling rig. According to the technical scheme, the impact type multifunctional airborne drilling rig comprises a positioning oil cylinder, a propulsion slide way pressing block, a slide way seat, a propulsion slide way, a propulsion cylinder, a clamp holder, a drill rod support, a drill rod support seat, a slide way top plate, a slide way, a slide way pressing block, a slide way bottom plate, a forward and reverse large torque transmission device, an impact type rock-drilling drilling rig, a rock-drilling drilling rig fixing plate, a fixing plate slide way pressing block, a first stage oil cylinder, a secondary oil cylinder, a chain assembly and an integrated valve group. The impact type multifunctional airborne drilling rig has the advantages that the rock drilling speed is fast, the impact efficiency is high, the noise is low, drilling tools are not prone to being stuck, good appearance is achieved, collision is avoided flexibly and effectively, a propeller is protected, the number of exposed oil pipes is greatly reduced, the occurrence of oil pipe extrusion is avoided, and the overall performance of the drilling rig is improved.

Description

technical field [0001] The invention belongs to the technical field of coal mine development machinery, and is used for blasting drilling in hard rock roadways under coal mines and various drilling holes in bolt and anchor cable support operations, and provides an impact-type multifunctional airborne drilling machine. Background technique [0002] In recent years, with the rapid development of my country's national economy, the demand for coal has also increased rapidly, so improving the driving efficiency of hard rock roadways has become a top priority. In the tunneling of hard rock and rock, the rock hardness is high, and the general hardness coefficient is f6-f10, and some can reach f14 or even higher. The loss of parts of ordinary rotary drilling airborne drilling rigs increases sharply with the increase of rock hardness, and the wear is serious. Replacement Frequent accessories and large loss of drill bits lead to an increase in excavation costs, and workers spend more ...

AI Technical Summary

Problems solved by technology

In the tunneling of hard rock and rock, the rock hardness is high, and the general hardness coefficient is f6-f10, and some can reach f14 or even higher. The loss of parts of ordinary rotary drilling airborne drilling rigs increases sharply with the increase of rock hardness, and the wear is serious. Replacement Frequent accessories and large loss of drill bits lead to increased excavation costs, and workers spend more time working under temporary support, which poses a greater safety hazard

To sum up, this ordinary support drilling process has low excavation efficiency, high labor intensity and poor safety, and is no longer suitable for the production needs of modern mines.
