Rock drill in-position detection device and rock drilling device

Abstract

The invention discloses a rock drilling machine in-position detection device and a rock drilling device. The rock drilling machine in-position detection device includes at least three movers, an origin device and a detector; the mover is configured to be arranged on the periphery away from the origin device, and the mover sends a wireless signal to the origin device; the detector is configured to be installed In the rock drilling machine, the displacement signal is sent according to the spatial displacement change of the rock drilling machine in a unit time; the origin device is configured to be installed on the rock drilling machine, and the origin device is constructed in a preset spatial coordinate system according to at least three previous wireless signals The initial coordinate point of the rock drill, and according to the displacement signal captures the termination coordinate point after the vector displacement of the initial coordinate point in the space coordinate system, the origin device corrects the termination coordinate point in the space coordinate system according to at least three subsequent wireless signals, the origin The controller will give an alarm according to the corrected termination coordinate point.

Description

technical field [0001] The invention relates to the field of rock drilling, in particular to an in-position detection device for a rock drilling machine. Background technique [0002] The rock drill is a tool used to mine stone. It drills blastholes on the rock formation, which is convenient for putting explosives to blast the rock, so as to realize the mining of stone or other stones; It is used to break hard layers of concrete and rocks. [0003] In geotechnical engineering, hand-held pneumatic rock drills are widely used to drill blast holes, and the diameter of the blast holes is generally between 30-50 mm. [0004] When the pneumatic rock drill is forming a hole, due to the shaking of the operator's hand, or the component force that is not parallel to the length direction of the shank generated when the shank hits the rock formation, the pneumatic rock drill does not move in a direction. If it is not reset in time, the hole diameter of the blast hole will be enlarged ...

AI Technical Summary

Problems solved by technology

[0004] When the pneumatic rock drill is forming a hole, due to the shaking of the operator's hand, or the component force that is not parallel to the length direction of the shank generated when the shank hits the rock formation, the pneumatic rock drill does not move in a direction. If it is not reset in time, the hole diameter of the blast hole will be enlarged irregularly, and the depth will not meet the design requirements of the blast hole.
