Description

Technical Field

[0001] This utility model relates to the field of construction operations in underground roadways of coal mines, and in particular to a multi-functional hydraulic grooving machine for mining. Background Technology

[0002] Currently, there are two main methods for excavating chambers in underground coal mine roadways: one is the traditional manual trenching, followed by manual drilling and anchoring. This method is not only inefficient and physically demanding for workers, but also poses safety hazards, significantly hindering rapid, safe, and efficient mine production. Another method uses tunneling machines, but these are large, difficult to maneuver, and their efficiency remains low, limiting their applicability. A third method uses specialized trenching machines, but these are limited in function and lack drilling and anchoring capabilities. After trenching, manual drilling and anchoring or the use of a separate drilling and anchoring machine is still required to achieve anchor support.

[0003] Therefore, it is evident that the existing grooving methods still have inconveniences and shortcomings, and urgently require further improvement. The question is how to create a new multi-functional hydraulic grooving machine that can achieve mechanized grooving and drilling / anchoring work, with high efficiency, reduced labor intensity for workers, and guaranteed worker safety during construction.

[0045] Before starting this multi-functional mining hydraulic grooving machine, a routine inspection is performed. Before the grooving machine reaches its designated position, the cutting arm 1, drilling arm mechanism 6, and rear outriggers 3-4 must be raised. Once the grooving machine is moved to the working position, the rear outriggers 3-4 are lowered. By controlling the hydraulic motor reducer 1-3, the boom pitch cylinder 1-6, the intermediate arm angle cylinder 1-7, and the forearm swing cylinder 1-8, the working head 1-9 is positioned to begin cutting. The working head 1-9 and the spray assembly 7-5 of the water system are activated, and cutting is performed by controlling the trajectory of the working head 1-9. After cutting at the current position is completed, the working head 1-9 and the spray assembly 7-5 are stopped, the cutting arm 1 is retracted, the rear outriggers 3-4 are raised, and the grooving machine is moved. The grooving machine is then moved to the next working position to begin a new round of cutting work or anchor bolt support work.

The drilling motor and the flushing assembly 7-4 of the water system are started, and drilling and anchoring work is performed by controlling the drilling motor. After drilling and anchoring are completed at the current position, the drilling motor and flushing assembly 7-4 are stopped, the anchor bolting machine 6-1 is retracted, the rear support legs 3-4 are raised, and the grooving machine is moved. The grooving machine is moved to the next working position to begin a new round of cutting or drilling and anchoring work.
