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

The invention discloses a rock drilling device propulsion one-way delay response method. A rock drilling device comprises a propulsion guide device, a propulsion control module and a drilling tool. The method comprises the following steps of (1) monitoring the torque of a rotating device by a rotation controlling module; (2) determining the loading state of the drilling tool according to the change of the torque; (3) when the drilling tool enters a load state from a non-load state, controlling a propulsion generating device to slowly increase the propulsion to the drilling tool. The invention also discloses the rock drilling device for realizing the rock drilling device propulsion one-way delay response method. The problems that the drilling tool is jammed and the drilling tool is repeatedly jammed reversely are solved, a rock drilling machine is guaranteed to normally drill, the rock drilling speed, the drilling precision and the production efficiency are increased, the damage to the rock drilling machine and the drilling tool is reduced, and the rock drilling cost is greatly reduced.

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...
