Abstract

The invention relates to the technical field of coal mine fully-mechanized coal mining conveyor driving systems, in particular to a full-automatic chain tightening permanent magnet driving system which comprises a permanent magnet semi-direct-drive motor and a full-automatic chain tightening system. The full-automatic chain tightening system comprises a motor chain tightening speed reducer, an electro-hydraulic control system, a connecting cover and an output gear. The full-automatic chain tightening system is arranged on the tail portion of the permanent magnet semi-direct-drive motor and occupies a small space, meshing and disengaging of the idle wheel of the motor chain tightening speed reducer and the output gear on the tail portion of the motor can be automatically achieved by operating the electro-hydraulic control system, a conveyor chain is automatically tightened after meshing, and braking is conducted after tightening reaches a program set value. According to the full-automatic chain tightening permanent magnet driving system of the invention, the problem that a permanent magnet drive conveyor cannot tighten a chain and brake at present is solved, so that a permanent magnet semi-direct drive system can be reliably applied to the conveyor.

Description

technical field [0001] The invention relates to the technical field of a driving system of a fully mechanized mining conveyor in a coal mine, in particular to a fully automatic tightening chain permanent magnet driving system. Background technique [0002] With the development of intelligence in coal mines and the demand for high efficiency and energy saving, permanent magnet frequency conversion integrated motors have been widely used in coal mine transportation equipment, but the permanent magnet frequency conversion integrated motors currently used are basically the same as ordinary asynchronous frequency conversion integrated machines in terms of speed and shape. It is consistent, and the motor and the conveyor still need a reducer and a hydraulic tensioning device. The transmission chain is very long, and the advantage is only that the power factor and efficiency are higher than ordinary motors. In the prior art, there is a permanent magnet semi-direct drive system, whi...
