Abstract

The embodiment of the invention discloses a mining unpowered automatic closing air door. The air door comprises two matched main air doors which are hinged to the two side walls of a roadway structurethrough a main hinge, auxiliary air doors are hinged to the main air doors through auxiliary hinges, starting handles are arranged on the auxiliary air doors, the auxiliary air doors are of front-arrangement right trapezoids with narrow upper and wide lower, the auxiliary air doors carry out inclined pivotal with the inclined sides of the right trapezoid as the door shaft, and balancing weights are arranged on the vertical door corners of the auxiliary air doors. The air door is simple in structure, a dedicated reset structure does not exist, the defect that in the technical method, a reset structure fails can be overcome, a seal pad with staggered tip corners is used for achieving seal, even under the condition of deforming and the like of the door frame, it is still ensured that air isnot leaked, and the automatic closing of the mining air door is achieved.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of mine air door devices, in particular to a mine-used automatic closing air door without power. Background technique [0002] Mine ventilation is an important part of mining operations. The ventilation structure is an important regulating device in the mine ventilation system, and the damper is the most commonly used facility in the ventilation structure. Therefore, the reliability of damper operation has an extremely important impact on underground production and personnel safety. Commonly used dampers have automatic opening / closing type and manual type. In order to facilitate the passage of people, an auxiliary damper is specially designed on the main damper. The operator passes through the auxiliary damper to travel between the roadways, thereby reducing the loss of air volume when passing through. The automatic dampers are controlled by motor, pneumatic or hydraulic drive elements...
