Detailed Description
As can be seen from fig. 1 to 3, the upward-sliding type opening mining automatic air door system disclosed in this embodiment includes an air door chamber 1, a door frame 2, an air door 3, a slide rail 4, a driving device, and a sensor.
The door frame 2 is arranged at the proper position of the two side walls of the roadway, and the air door chamber 1 is excavated and formed behind the door frame 2 corresponding to the top plate of the roadway.
The door frame of this embodiment is preferably a concrete square column structure, and each side is provided with two square columns respectively.
The length of the damper chamber 1 is greater than the height of the damper.
The slide rails 4 are arranged on the left and right and are L-shaped, long edges and short edges of each slide rail are respectively fixed on the side walls of the roadway and the air door chamber 1, and the short edges are positioned between two square columns of the door frame on each side at the installation positions of the side walls of the roadway.
The air door 3 is formed by splicing a plurality of door leaves 31 from top to bottom, the diagram shows that the four door leaves are spliced, the door leaves are spliced by hinges, and the height of the air door after splicing is slightly larger than that of a roadway.
At least two side pulleys 32 are fixed to the side edges of both ends of each door leaf of the damper of the present embodiment, and are mounted on the slide rail 4 via the side pulleys.
Of course, the installation mode that the sliding groove is matched with the sliding rail can be adopted at the two ends of the air door in other embodiments.
The driving device is positioned on the central plane of the width direction of the air door 3 and comprises a motor 5, a linear guide rail 6, a screw rod 7, a nut seat 8 and an air door connecting piece.
The linear guide rail 6 is fixed along the center face of the top plate of the air door chamber 1, two ends of the screw rod 7 are fixed on the linear guide rail 6 through bearings and bearing seats respectively, and the nut seat 8 is connected on the screw rod 7. The motor 5 is fixed at the far doorframe end of the top plate of the air door chamber 1, and the output shaft of the motor is connected with the screw rod 7 through a coupling (the coupling is not shown in the figure).
The motor of the embodiment adopts a servo motor capable of rotating forward and backward.
The damper connection may be a pull rod or a pull rope, and the preferred pull rod 9 of this embodiment is used as the damper connection to ensure better stability in the damper movement process.
One end of the pull rod is connected with the nut seat, the other end of the pull rod is connected with the door leaf close to the air door chamber, the connection modes of the two ends are hinged, the nut seat and the side wall close to the door leaf of the air door chamber are respectively provided with a hinged seat, the two ends of the pull rod are respectively provided with a hinged ring, and the hinged rings are hinged with the hinged seats through pin shafts.
The working principle of the driving device for realizing the opening and closing of the air door is as follows:
when the motor 5 works, an output shaft of the motor drives the screw rod 7 to rotate, and the screw rod rotates to enable the nut seat 8 on the screw rod to move along the screw rod, namely the rotation motion of the screw rod is converted into the linear motion of the nut seat along the screw rod. When the nut seat moves along the screw rod, the pull rod 9 drives the air door to slide up and down along the slide rail.
In order to realize automatic opening and closing of the air door, a pair of sensors 10 is respectively arranged in the roadway corresponding to the front of the door frame and the rear of the air door chamber.
The damper is normally closed.
When the sensor monitors that people or vehicles approach the air door, a signal is sent to the motor, the motor works in the forward direction, and the pull rod pulls the air door upwards along the slide rail and stops in the air door chamber to enable the people or the vehicles to pass through.
When the sensor monitors that a person or a vehicle is far away from the air door chamber, a signal is sent to the motor, the motor works in the reverse direction, the nut moves in the reverse direction along the screw rod, the air door is reset to block the roadway, so that wind current cannot pass through the roadway, and the short circuit of the underground wind current is avoided.
In order to avoid collision with the air door during the running process of the vehicle, the air door chamber opening is further provided with a protective guard 11 in the embodiment.
