Cutting test bench for cutting head of heading machine

Abstract

The invention discloses a cutting test bench for a cutting head of a heading machine, relates to the field of industrial and mining mechanical equipment testing. The cutting test bench comprises a sliding platform, a rotary platform, a cutting head driving device, a cutting head and a simulated coal rock, wherein the sliding platform comprises a sliding platform bottom plate, a first hydraulic oilcylinder and guide rails; the rotary platform comprises a rotary platform bottom plate, a second hydraulic oil cylinder, a third hydraulic oil cylinder, a rotary shaft and a thrust bearing; the cutting head driving device comprises a motor, a gear reducer and a cutting head driving shaft; the simulated coal rock comprises a simulated coal wall, a coal rock base, a supporting frame and a pluralityof lifting oil cylinders. The cutting test bench provided by the invention is used for simulating a dynamic evolution process of crushing and collapsing the coal rock by the cutting head so as to avoid influence of harsh and complex working conditions on the actual working process of the cutting head, and is of a great significance in acquiring key data such as the cutting specific energy consumption and the cutting efficiency of the cutting head.

Description

technical field [0001] The invention relates to the field of testing of industrial and mining machinery equipment, in particular to a cutting test bench for cutting heads of roadheaders. Background technique [0002] The cutting head is the main working mechanism of the roadheader. The picks arranged on it are in direct contact with the coal rock mass, causing elastic-plastic deformation and crushing of the coal rock mass, releasing a large amount of energy and forming a large amount of coal rock particles and dust. The inevitable phenomenon of coal mining and tunneling work. It is the result of multiple factors such as the structure and motion parameters of the cutting head itself, material properties, and the conditions of coal and rock mass. These factors will directly or indirectly affect the dynamic evolution process of the cutting head for breaking and collapsing coal and rock. If the process cannot be accurately revealed, the design basis of the cutting head of the r...

Problems solved by technology

In addition, the underground roadway is narrow, and various pipelines, vehicles, pedestrians, wind currents, etc. pass or move in it, which will inevitably cause large data disturbances, making it difficult to accurately identify various parameters, and data collection is difficult and expensive
