Abstract

The invention relates to multi-body discontinuous coal petrography cutting equipment. The equipment comprises a crawler unit and a supporting platform arranged on the crawler unit, wherein a master control platform, an electric cabinet, a pumping station, a reducer and a hydraumatic thrust unit are successively fixed on the supporting platform, the root of the output shaft of the reducer is provided with a fixed sleeve, the head of the output shaft of the reducer is provided with a multi-body discontinuous cutting coal petrography device arranged at one side of the supporting platform, and the multi-body discontinuous cutting coal petrography device is obliquely arranged; the electric cabinet is used for controlling the start and stop of a motor of the pumping station and a cutting motor,and the master control platform is used for controlling the walk of the crawler unit and the stretching of a hydraulic cylinder of the hydraumatic thrust unit; the cutting motor transfers power to the multi-body discontinuous coal petrography cutting device through the reducer for cutting, the excavation efficiency of a downhole gutterway and a ground gutterway can be effectively improved; the whole manoeuvrability of the equipment is flexible, and the cutting is efficient; a rock mass with hardness f<6 can be broken so as to meet an excavation requirement of a downhole drainage ditch, a human input is saved, the mechanization degrees of a coal mine and surface engineering are improved, and the mechanization excavation of the downhole drainage ditch is realized.

Description

Technical field [0001] The invention relates to a multi-body discontinuous cutting coal and rock equipment, and is particularly suitable for excavation of underground drainage ditch in coal mines and trenching in ground engineering. technical background [0002] With the development of coal mining technology and engineering machinery technology, the degree of coal mines and engineering mechanization in my country continues to increase, and the types and forms of machinery used are increasing, but they still cannot meet production needs. For example, the roadway drainage ditch is an important part of the underground drainage system. When designing the roadway, the drainage ditch needs to be excavated on both sides of the roadway. Because the drainage ditch is generally narrow and lower than the roadway ground, it cannot be completed by the roadheader. They are all hard rocks, which are difficult to excavate. At present, they are mainly used to loosen them by drilling and blasting ...
