Vertical rock drilling device and drilling method

Abstract

The invention relates to the technical field of drilling, and provides a vertical rock drilling device and a drilling method. The vertical rock drilling device comprises a driving device, supporting devices, drilling devices and spraying devices, wherein the supporting devices are uniformly arranged at the lower end of the driving device in a hinged mode, the drilling devices are installed in the driving device in a threaded connection mode, the spraying devices are arranged on the outer walls of the drilling devices in a sleeving mode, and the spraying devices are fixed to the supporting devices through air pressure rods in a hinged mode. According to the vertical rock drilling device and the drilling method, the main technical defects in the rock drilling process can be overcome by adopting a vertical mode, wherein the main technical defects are that a drilling machine is prone to shaking in the drilling process, so that the drilling quality is influenced; in addition, a drilling cylinder and an annular drilling tool can rub with rock to generate high temperature in the drilling process, so that the rigid strength of the annular drilling tool and the drilling cylinder is reduced, and continuous drilling work is influenced; and dust generated in the drilling process can be dispersed around a hole, so that the construction environment is influenced.

Description

Technical field [0001] The present invention relates to the field of drilling techniques, and more particularly to a vertical rock drilling device and a drilling method. Background technique [0002] Gravel rock is also called the shaft of sandstone, which is mainly sandstone particles at different particle size levels. It belongs to the sandstone sandstone; the gravel rock is mainly muddy fine group (including stucco, cloud mud, clay sludge) And sand grade, powder grade coarse glutinous group, and the cement is mainly carbonate, with a small amount of green mud and yellow iron ore. [0003] The existing driller has the following problems in the process of gravel rock drilling: the drilling process is easily shaking, which affects the quality of the drilling, and drilling drill and ring drill High temperature in the rock friction, resulting in a decrease in rigidity in the annular drill and drill cylinder, affecting the continuous progression of the drilling operation, and the du...

AI Technical Summary

Problems solved by technology

[0003] The existing drilling machine mainly has the following problems in the process of drilling sandy conglomerate: the drilling machine is easy to shake during the drilling process, thereby affecting the quality of the drilling, and the drill barrel and the annular drill bit will be damaged during the drilling process. Friction with the rock will generate high temperature, which will reduce the rigidity of the annular drill bit and the drill barrel, which will affect the continuous drilling work, and the dust generated during the drilling process will be dispersed around the hole, thus affecting the construction environment
