Problems solved by technology

However, such system settings are often more complicated and costly, and the same advance speed cannot be applied to drilling work under different rock formation conditions
When the condition of the rock formation changes, it is necessary to quickly set different propulsion speeds according to the condition of the rock formation at any time. The operation is more complicated, and in most cases only experienced operators can do it

Abstract

Disclosed are a propulsive force one-way delayed response method for a rock drilling apparatus and a rock drilling apparatus implementing the propulsive force delayed response method. The drilling apparatus comprises a propulsion guidance device (1), a propulsion control module (202) and a drilling tool (4). The method involves the following steps: 1) monitoring the magnitude of the torque of a rotation device (302) by means of a rotation control module (304); 2) determining the load state of the drilling tool (4) from a change in the magnitude of the torque; and 3) when the drilling tool (4) moves from a state with no load to a loaded state, controlling a propulsive force generating device (2) to exert a slowly increasing propulsive force on the drilling tool (4). The rock drilling apparatus and the propulsive force delayed response method solve the problems of jammed drills and repeatedly jamming in reverse, ensuring normal drilling operation of a rock drilling rig (3), increasing drilling speed, drill hole precision and production efficiency, and reducing damage to the rock drilling rig (3) and the drilling tool (4), significantly reducing rock drilling costs.

Description

technical field [0001] The invention relates to the field of rock drilling machine control, in particular to a method for one-way delayed response of the propulsion force of a rock drilling device, and also relates to a device for realizing the method. Background technique [0002] Impact, propulsion, rotation and slag discharge are the four basic links of rock drill drilling work, which are mainly through the propulsion guiding device, propulsion generating device, rotation control module, propulsion control module, impact control module, rock drill and drilling tools. The rock drill includes a rotary device and an impact device to realize the drilling action. The propulsion guide device plays a guiding role when drilling, and the propulsion generating device generates propulsion acting on the rock drill, so that the drilling tool is in close contact with the rock at the bottom of the hole. At the same time, the rotating device will generate a rotating torque to make the d...
