Problems solved by technology

However, in the face of hard rock with good integrity and high strength, the rock mass cannot be cut quickly only by the mechanical effects of wedge, cutting, and pressure of the cutter head, and the rock mass is often ground into rock powder and the drilling hole is blocked. , greatly reducing the drilling efficiency

Abstract

The invention discloses an intelligent drilling device for underground engineering and a heading machine. The drilling device comprises a drilling mechanism, a detection module and a control module. The drilling mechanism is arranged on a fixed disc and comprises a drill rod capable of axially extending and retracting on the fixed disc and a driving assembly used for driving the drill rod to axially extend and retract and axially rotate. The detection module is used for detecting rock debris in the process that the drilling mechanism drills into to-be-excavated rock mass and rock mass physicaland mechanical parameters of the to-be-excavated rock mass, and analyzing the lumpiness size and the weight distribution rule of the rock debris. The control module is used for adjusting the parameters generated when the driving assembly drives the drill rod to axially extend and retract and / or axially rotate according to the lumpiness size and the weight distribution rule of the rock debris. Parameter adjustment of the drilling mechanism is highly matched with the geological conditions of the to-be-excavated rock mass in real time, then the mechanical performance of the drilling device is better exerted, and the aim of rapid drilling is achieved.

Description

technical field [0001] The invention belongs to the technical field of roadheaders, and in particular relates to an intelligent drilling device and a roadheader for underground engineering. Background technique [0002] Whether it is for drilling and blasting construction or mechanical excavation, drilling construction is of great significance to engineering construction, which determines the progress, economy and safety of the project. However, under the conditions of complete extremely hard rock construction (cracks are not developed, rock mass integrity is high, and the uniaxial compressive strength of rock is greater than 150MPa), drilling construction has poor adaptability to hard rock, and the performance of drilling machinery cannot be fully utilized. , resulting in low efficiency of engineering excavation, delaying the progress and cycle of the project. Especially in the face of complex geological conditions, the drilling device is poorly sensitive to geological con...
