Coal mining machine walking monitoring system

Abstract

The invention discloses a coal mining machine walking monitoring system including a tilt angle detection unit, a walking speed detection unit and a walking monitoring box, the walking monitoring box comprises a box body, an electronic circuit board and a control panel, the electronic circuit board is provided with a data storage unit, a data processor, a data acquisition circuit and a power module, maximum walking speeds corresponding to different tilt angles of coal mining machine body in the down-dip mining and up-dip mining process are stored in the data storage unit, the data processor automatically matches the maximum walking speed of the monitored coal mining machine under the current status according to the information detected by the tilt angle detection unit, and the data acquisition circuit and the power module are respectively connected with the data processor, a display unit is installed on the side wall of the box body, and a walking traction motor of the monitored coal mining machine is controlled by a walking controller. The coal mining machine walking monitoring system has the advantages of simple structure, reasonable design, convenient operation and use, and good use effect, and can effectively solve the problems of low intellectualization degree of the coal mining machine in the walking process, higher requirements of driver manipulation level, walking state instability, and the like.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a coal mining machine walking monitoring system. Background technique [0002] A coal shearer is a coal mining machine that breaks coal with a rotating working mechanism and reloads the broken coal into a conveyor or other transportation equipment. It is one of the key and indispensable equipment in coal mining machines. , plays a vital role in the entire coal mining process. The mechanism and function of the shearer itself are relatively complex. It is a large and complex system integrating machinery, electricity and hydraulic pressure, and the working environment is harsh. It is affected by the geological environment of the coal mining area and the geographical environment of the coal mining roadway where it is located. Larger, once the shearer breaks down in the actual working process, the entire coal mining work will be interrupted, resulting in huge economic losses. Nowadays, with th...

Problems solved by technology

However, most of the existing coal mining machines are not equipped with a dedicated walking monitoring system. During the actual coal mining process, the drivers rely on the road data from temporary surveys on the spot and previous driving experience to drive and control the coal mining machine walking motor. In the process of use, there are problems such as low intelligence, high requirements on the driver's control level, and unstable walking state, especially when mining large-dip coal seams, the above problems are more obvious.
