The invention belongs to the field of mining equipment and particularly relates to a mining high-voltage distribution switch circuit breaker electric propulsion mechanism which can be manually operated and automatically controlled. The mining high-voltage distribution switch circuit breaker propulsion mechanism comprises a circuit breaker and a box body, wherein a quick opening door is arranged on the box body, a crank and rocker mechanism for controlling propulsion of the circuit breaker is arranged at the bottom of the box body, and a gear-rack mechanism and an electric drive mechanism are arranged inside the box body. Propulsion of the circuit breaker and integration of manual operation and automatic operation on quick opening door closing are realized. On one hand, the requirement on miniaturization of a high-voltage distribution switch is met, and on the other hand, circuit breaker propulsion and quick opening door closing automation are realized.
Description
technical field [0001] The invention belongs to the field of mining equipment, and in particular relates to a manually operated and automatically controlled propulsion mechanism of a mine high-voltage power distribution switch circuit breaker. Background technique [0002] At present, the simple crank rocker mechanism is generally used in the propulsion of the circuit breaker of the high-voltage distribution switch in the coal mine, which is the most used form of the high-voltage distribution switch. Due to the limitation of the size of the rocker mechanism, it cannot be used in the small space of the mine-used high-voltage distribution switch circuit breaker, and it needs to be improved. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention designs an electric propulsion mechanism suitable for a mine-used high-voltage power distribution switch circuit breaker suitable for small boxes, and can realize manual operation and aut...
