Coal mine underground wet concrete injection machine monitoring system and method

Abstract

The invention discloses a monitoring system and method for a wet-type concrete spraying machine in a coal mine and belongs to a concrete spraying machine system and method. The monitoring system for the wet-type concrete spraying machine in the coal mine comprises a first sensing unit, a first signal processing unit, a second sensing unit, a second signal processing unit, a third sensing unit, a third processing unit and a control center. The first sending unit and the first signal processing unit are arranged in a pumping system, the second sensing unit and the second signal processing unit are arranged in a spiral conveying mechanism, and the third sensing unit, the third processing unit and the control center are arranged in a mixing system. The monitoring system and method have the advantages that reliability and the intelligentization degree are high, meanwhile multiple sensors are used in a combined mode, and the working state and monitoring information of the machine are displayed in real time through a man-machine interaction device. The overall system can control the spraying state and eliminate common faults effectively, rapidly and reliably, and automatic control over the wet-type concrete spraying machine can be achieved.

Description

technical field [0001] The invention relates to a concrete spraying machine system and method, in particular to a monitoring system and method for a coal mine underground wet concrete spraying machine. Background technique [0002] When bolting and shotcreting support roadways in coal mines, dry concrete spraying machines are often used. This process has low rebound rate, large amount of dust, poor quality concrete and low production efficiency, which is extremely harmful to workers. Concrete spraying has significant advantages in comparison, but the current wet spraying uses an independent mixing station for mixing, which has complicated procedures and a large footprint, and is not suitable for working in a small area underground in coal mines. Combined use of spraying machines, continuous mixing cannot be achieved, the production efficiency is low, and the quality of the output concrete is uneven. At the same time, due to the harsh underground environmental conditions, onc...
