Problems solved by technology

[0002] In recent years, with the modernization, high-end, and intelligent development of coal mine equipment, the power of electromechanical equipment has become larger and larger, and high-power frequency conversion equipment has become more and more widely used in coal mine production. At the same time, underground power and control systems are required to have reliable performance, The characteristics of small size, light weight, complete functions, and high degree of intelligence. The traditional power unit is mechanically coupled with the inverter, motor, and reducer. The mechanical and electrical interfaces are very complicated. The overall system structure is huge and costly. The volume of the inverter Large, generally placed on the equipment train with a long distance, errors are prone to occur due to long-distance transmission signals during use, and the existing frequency conversion and deceleration all-in-one machine directly rigidly fixes the frequency converter, motor and reducer together, and the frequency converter is directly fixed On the motor casing, the structure is single and the volume is large. In coal mines, the underground roadway is narrow and the equipment is too large, which makes transportation and maintenance difficult. The pedestrian space is small so that personnel safety and work efficiency cannot be guaranteed, and it cannot meet the requirements for supporting the underground working face, resulting in frequency conversion and deceleration Direct drive technology cannot be really popularized and applied

[0003] In the prior art, the frequency converter is directly fixed on the shell of the frequency conversion motor. Although the purpose of the integrated design of the frequency converter and the frequency conversion motor is achieved, the distance between the frequency converter and the frequency conversion motor is shortened, and the problem of signal transmission is improved, but it is also As a result, the overall structure of the frequency conversion motor becomes larger, which cannot meet the requirements for supporting the use in the small underground space, resulting in limited use, and does not improve the equipment's response to the small underground working environment

The fixed connection of the frequency converter leads to an increase in the volume of the equipment, which seriously affects the equipment matching and the underground work of the personnel, making the overall installation and maintenance of the frequency conversion and deceleration machine difficult, and brings inconvenience to the actual underground use. Therefore, we propose a new type of combined frequency conversion All-in-one reducer
