Grooving machine

Abstract

The invention discloses a grooving machine, which comprises a self-walking mechanism, a working arm rotating mechanism, a working arm mechanism, a cutting mechanism, and a power and control mechanism, wherein the self-walking mechanism is arranged at the bottom of the grooving machine; a mounting platform is arranged at the upper part of the self-walking mechanism; the working arm rotating mechanism and the power and control mechanism are arranged on the mounting platform; the working arm rotating mechanism comprises a turbo-worm reducer and a working arm mounting holder connected with an output shaft of the turbo-worm reducer; the turbo-worm reducer is fixed on the mounting platform; the working arm mechanism is rotatably connected onto the working arm mounting holder and is connected with the cutting mechanism; the power and control mechanism is connected with and controls actions of the self-walking mechanism, the working arm mechanism, the working arm rotating mechanism and the cutting mechanism. A grooving working arm can rotate freely for 360 degrees; the stability coefficient of the grooving machine can be increased through an expendable stabilizing support leg mechanism; the mechanical grooving operation is realized; the grooving efficiency is improved; the labor intensity is alleviated and the safety coefficient is increased.

Description

technical field [0001] The invention relates to the technical field of grooving an underground connecting road in a coal mine, in particular to a fully hydraulic connecting road slotting machine. Background technique [0002] With the development of science and technology in the coal industry and the requirements of my country's industrial policy, since the 1980s, advanced bolt and cable support technology has been widely used in coal mine roadway excavation in my country. The extensive use of tunneling equipment such as fully mechanized excavators and continuous miners has enabled mechanized coal dropping and coal loading in the tunneling face, thus greatly increasing the tunneling speed. The use of the new anchor rod and cable drilling rig makes the support speed basically keep up with the excavation speed. As the speed of tunneling increases, the number of slots that need to be slotted in the connecting roadway also increases. [0003] At present, the grooving operation...
