Non-contact monitoring device and non-contact monitoring method for load process of coal-mine excavating mechanical track walking system

Abstract

The invention belongs to the technical field of monitoring of coal-mine excavating mechanical track walking mechanisms, particularly relates to a non-contact monitoring device and a non-contact monitoring method for load process of a coal-mine excavating mechanical track walking system, and aims at providing a track mechanical walking mechanism monitoring method and a load identification technology which are high in reliability and good in stability and timely providing the load process of the track walking mechanism so as to guarantee the quality and the service life of the track walking mechanism. The monitoring device comprises an upper computer and a lower computer built in a measured track plate of the track walking system. The lower computer comprises a strain gauge and a collecting emission module which is connected with the strain gauge and has a wireless emission function. The upper computer comprises a background and a control unit having a wireless receiving function. The non-contact monitoring device and the non-contact monitoring method have the advantages of mastering a technical state of a mechanical bearing structure during work at any time, achieving long-term on-line monitoring of a track walking mechanical structure, saving plenty of manpower and funds, being convenient and fast and having high practical value and economic value.

Description

technical field [0001] The invention belongs to the technical field of monitoring a crawler belt traveling mechanism of a coal mining excavating machine, and in particular relates to a non-contact monitoring device and method for a load history of a crawler belt walking system of a coal mining excavating machine. Background technique [0002] With the continuous increase of my country's demand for coal and the continuous improvement of the mechanization of coal mining, crawler machinery has a large ground area, low ground pressure, high output power, good adhesion performance, strong climbing ability, small turning radius, and cross-ditch Features such as strong ability to cross ridges are particularly important in the operation of various complex roads such as soft and muddy underground in coal mines. Most large-scale mining machinery uses crawler walking mechanisms. [0003] The crawler traveling mechanism is an important part of crawler machinery such as continuous coal mi...

Problems solved by technology

[0006] The methods to determine the dynamic load mainly include direct method and indirect method. The direct method is to directly measure the size of the dynamic load or measure the parameters related to the dynamic load to convert the size of the load. Dynamic loads are difficult, if not impossible, to measure directly
