Problems solved by technology

There are many difficulties in the start and stop of the existing roadway damper, the vehicle cannot be started and stopped automatically when passing, and it needs manual switching, which is time-consuming and labor-intensive, which affects the automatic mining speed of coal mines.
Moreover, the safety performance of the roadway damper is poor. When the object to pass through the door passes through the door, once the door panel loses control, it will squeeze the object to be passed, causing casualties, equipment damage, and door panel damage.
[0004] In addition, the roadway damper is customized for the roadway. Due to the differences between the roadways, the versatility of the roadway damper is poor, and the reuse rate is low, resulting in waste of resources

Abstract

The invention discloses a roadway air door. The roadway air door comprises a door frame, an air door body, a driving mechanism, a first sensor and a control mechanism. The door frame is provided witha doorway for an object to pass through, the air door body is rotatably connected with the door frame, and the air door body is used for sealing or opening the doorway. The driving mechanism is arranged on the door frame and used for driving the air door body to rotate back and forth, the first sensor is used for monitoring and collecting the distance information between the object to pass throughand the doorway, and the first sensor outputs a monitoring signal. The control mechanism receives the monitoring signal, compares the monitoring signal with a preset signal, and controls the drivingmechanism to forwardly or reversely drive the air door body to rotate according to the comparison result. The quick and automatic start and stop of the roadway air door can be realized, and the safetyperformance is improved.

Description

technical field [0001] The present invention relates to mine ventilation equipment, more specifically, to a roadway damper. Background technique [0002] Whether the ventilation system can run stably, reliably and safely directly affects the safe production of the mine, and stable ventilation equipment is a necessary condition for the reliability and stability of the ventilation system. The roadway damper is an important structure in the ventilation equipment, which is used to cut off the air flow in the roadway to adjust and control the wind speed and flow in the roadway; it is also used for vehicles and people waiting to pass through the objects in the roadway quickly. [0003] Whether the roadway damper can be started and stopped quickly is an important criterion for testing the performance of the roadway damper. The existing roadway dampers are difficult to start and stop, vehicles cannot be started and stopped automatically when passing, and manual switching is time-co...
