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

Abstract

The invention relates to the field of drilling technology, and provides a vertical rock drilling device and a drilling method, including a driving device, a supporting device, a drilling device and a spraying device; the lower end of the driving device is uniformly provided with a supporting The device is located inside the driving device and is equipped with a drilling device through a threaded connection. The spray device is sleeved on the outer wall of the drilling device, and the spray device is fixed on the support device in a hinged manner through an air pressure rod; the present invention adopts a vertical It can solve the main technical defects in the process of drilling rocks: the drilling machine is easy to shake during the drilling process, which affects the quality of the drilling, and the drill barrel and annular drill will rub against the rock during the drilling process The high temperature will lead to the reduction of the rigidity of the ring drill and the drill barrel, affecting the continuous drilling work, and the dust generated during the drilling process will be dispersed around the hole, thereby affecting the construction environment.

Description

technical field [0001] The invention relates to the technical field of drilling, in particular to a vertical rock drilling device and a drilling method. Background technique [0002] Glutenite is also called pebble-bearing sandstone. It is mainly composed of sandstone particles of different particle sizes and belongs to composite sandstone; the interstitial material of glutenite is mainly mud-level fine matrix (including stucco, cloud mud, clay mud matrix) And sand grade, silt grade coarse mixed base, cement is mainly carbonate, containing a small amount of chlorite and pyrite. [0003] The existing drilling machine mainly has the following problems in the process of drilling sand 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 generates high temperature, which leads to a decrease i...
