Abstract

The invention discloses a development test platform for drum type coal mining machine advanced cutting transmission system, comprising a mechanical part and a measurement and control part, wherein the mechanical part comprises a driving part, a transmission part and a loading part; the loading part and the transmission part are connected through an inertial flywheel; the driving part and the transmission part are connected through a star type coupler; a first rotation speed torque sensor is positioned between the transmission part and the star type coupler; the measurement and control part comprises an upper computer and a controller; the upper computer transmits an order to the driving part and the loading part through the controller and receives data transmitted from the driving part, the transmission part and the loading part. The development test platform is complete in functions, small in occupied space, high in feasibility, good in stability, good in controllability, low in cost and easy to implement.

Description

technical field [0001] The invention specifically relates to a comprehensive experimental platform for testing electromechanical dynamic characteristics of a cutting drive system of a drum shearer and developing advanced control strategies. Background technique [0002] Coal is the main energy source of our country at present and for a long time in the future. Coal mining machines are the key equipment in coal mine production. The development of coal mining to deep high-risk coal seams makes the working conditions of coal mining equipment more complex, harsh, frequent accidents and failures. Maintenance is difficult, and the long equipment maintenance cycle causes huge economic losses. At present, the commonly used drum shearer only has adjustable traction speed but not drum speed. The coal mining rate is low and the adaptability to sudden change conditions is poor. At the same time, as one of the main working mechanisms of the drum shearer, the cutting part has many transm...
