Mine saw control device and working method thereof

Abstract

The invention relates to a mine saw control device and a working method thereof. The mine saw control device comprises saw blades arranged on a mine saw machine body, main motors for driving the saw blades to rotate, traveling wheels arranged on the mine saw machine body, an advancing motor for driving the traveling wheels to advance, and a hydraulic lifter used for driving the saw blades to ascend and descend, a collector used for collecting working currents of the main motors in real time is further arranged on the mine saw machine body and electrically connected with a first port of a PLC so as to transmit numerical values of the real-time working currents of the main motors to the PLC; a second port of the PLC is electrically connected with an advancing frequency convertor for controlling the advancing motor to work so as to control the rotating speed of the advancing motor in real time; and a third port of the PLC is electrically connected with the hydraulic lifter so as to control the one-time cutting amount of the saw blades driven by the hydraulic lifter. According to the mine saw control device, the operation trouble and the harm to the body of an operator are reduced advantageously, and the phenomena of damage to the main motors due to overloading and heating or cutter breaking can be greatly reduced.

Description

Technical field: [0001] The invention relates to a mine saw control device and a working method thereof. Background technique: [0002] Mine saw is a kind of equipment for stone mining. It has many types of structures, but there is a problem that when sawing mine stone, it is impossible to know the hardness of the stone at each position in the deposit, so that the mine saw will When it is hard stone, it is still running at high speed, which may easily cause the main drive motor to overload, heat, damage or break the knife. In order to reduce the occurrence of the above phenomenon, the current operation of the mine saw requires very experienced workers. Even so, the above phenomenon still occurs from time to time. occurred, thereby not taking advantage of the widespread use of mining saws. Invention content: [0003] The invention provides a mine saw control device and a working method thereof. The mine saw control device has a simple structure, a reasonable design, and is...
