Abstract
The invention discloses an extension pipe type belt conveyor for an underground gate way. The extension pipe type belt conveyor is composed of a machine head portion, a retractable middle frame and a machine tail portion. The machine head portion is provided with a belt storage device and a tensioning device, and the belt storage device and the tensioning device are used for storing and tensioning a conveying belt when the conveyor conducts retraction. The retractable middle frame can automatically retract under the action of external force, so that the conveyor retracts. A stepping self-moving machine tail of the machine tail portion can safely and reliably move in a one-button mode. Automatic stretching and retraction of the extension pipe type belt conveyor can be achieved. When the belt conveyor needs to be shortened, the self-moving machine tail moves forwards to compress the retractable middle frame, meanwhile, the belt storage device and the tensioning device of the machine head portion conduct tensioning, and then automatic retraction can be achieved. The starting device of the extension pipe type belt conveyor is a controllable magnetic soft-starting device which can achieve soft starting of the conveyor. By the adoption of the extension pipe type belt conveyor for the underground gate way, automatic stretching and retraction can be achieved, scattered dust, coal and the like can be reduced in the underground transportation process, and green, efficient and continuous transportation can be achieved.
