Detailed Description
Referring to fig. 1-5, a mine ventilation control system includes two air doors disposed in a mine tunnel in sequence and a linkage locking device disposed between the two air doors, wherein the linkage locking device is used to open and close the two air doors to prevent the two air doors from being opened simultaneously. The hinged sides of the door body 1 and the door frame 2 of the two air doors are both positioned on the same side, as shown in fig. 1, that is, the hinged sides of the door frame 2 and the door body 1 of the two air doors are both right sides, and then the movable sides are both left sides; or the hinged sides are the left sides, and the movable sides are the right sides. The linkage locking device comprises a mounting box fixedly arranged on the side wall of the roadway and a linkage locking mechanism arranged in the mounting box. The installation box comprises box 3 and the flat-open chamber door 4 that sets up in the positive of box 3, and chamber door 4's setting can be convenient for to linkage blocked mechanical system's maintenance and maintenance.
As shown in fig. 3, the interlocking mechanism includes a swing frame 5 disposed at a middle lower portion of the inside of the box 3 and extending along a width direction of the box 3, and a center rod 6 extending along a thickness direction of the box 3, a connection hole is disposed at a middle portion of the swing frame 5, and the center rod 6 is inserted into the connection hole and is hinged to the swing frame 5. After the swing frame 5 is hinged with the central rod 6, the swing frame 5 can rotate around the central rod 6, the simplest swing frame 5 is a swing rod, and the middle part of the swing rod is hinged with the central rod 6.
Two ends of the swing frame 5 are respectively connected with the bottom surface of the box body 3 through a first spiral spring 7, and the swing frame 5 is in a horizontal state under a normal state. Two side walls of the upper part of the box body 3 are respectively provided with a first rope hole 8, and a first guide wheel 9 is arranged in the box body 3 at a position opposite to the first rope hole 8. The linkage locking mechanism further comprises two steel ropes 10, one ends of the steel ropes 10 are connected with two ends of the swing frame 5 through second spiral springs 11 respectively, and the other ends of the steel ropes pass through the first guide wheels 9 and the first rope holes 8 in sequence and then are connected with the door bodies 1 of the two air doors. In order to make the steel cable 10 have a sufficient tensile force on the door body 1, it is better that the connection between the door body 1 and the steel cable 10 is located at the upper part of the door body 1 far away from the hinge side, that is, the connection between the door body 1 and the steel cable 10 is located at the upper part of the movable side of the door body 1. Meanwhile, in order to improve the stability of the steel cable 10, as shown in fig. 1 and 4, a second cable hole 15 is formed at a position of the door frame 2 opposite to the upper portion of the movable side of the door body 1, a second guide wheel 16 is disposed in the second cable hole 15, and the steel cable 10 is connected to a pull ring 17 fixedly disposed on the outer surface of the door body 1.
The working principle of the invention is as follows: in the normal state, both dampers are closed, and the swing frame 5 is in the horizontal state. When an air door needs to be opened, the door body 1 is pulled, the door body 1 drives the steel rope 10, the steel rope 10 drives the swing frame 5 to rotate, and one end, close to the opened air door, of the swing frame 5 tilts up and the other end of the swing frame swings down; one end of the swinging frame 5 which swings downwards tightly takes the steel rope 10 and the second spiral spring 11 which correspond to the other air door. Thereby ensuring that one of the two air doors is in a closed and the other is in an openable safe state. Meanwhile, the invention has simple structure and convenient maintenance, does not use a motor, an air cylinder and the like to control the air door and has extremely high safety.
Since the swing frame 5 is a core stressed component of the present invention, in order to further improve the stability of the motion of the swing frame 5, it is better to adopt a method that, as shown in fig. 5, the swing frame 5 is in a rectangular frame shape, connecting pieces 18 are respectively arranged at two ends of the swing frame 5, connecting rings 19 are respectively arranged on the upper surface and the lower surface of the connecting pieces 18, and the swing frame 5 is connected with the first helical spring 7 and the second helical spring 11 through the connecting rings 19; a short sleeve 20 is fixedly arranged in the middle of the swing frame 5 along the width direction, and the connecting hole is a pipe hole of the short sleeve 20; two limiting discs 21 are further arranged on the central rod 6, and the distance between the two limiting discs 21 is matched with the width of the swing frame 5. The swing frame 5 adopting the mode can not slide on the central rod 6 when swinging, and the swing frame 5 has better stability and longer service life.
Because the environment in a mine is complex, two air doors are often required to be opened or closed simultaneously in case of disasters and dangerous situations, for this reason, as shown in fig. 3, a vertical guide rail 12 is further arranged on the inner wall of the back of the box body 3, a sliding block 13 is adapted on the guide rail 12, the central rod 6 is fixedly arranged on the sliding block 13, the sliding block 13 is driven by a lifting driving part 14 fixedly arranged at the bottom of the box body 3, and the lifting driving part 14 is used for driving the sliding block 13 to move up and down on the guide rail 12, which is commonly used as: cylinders, linear motors, etc., but in view of the risk of live equipment working downhole, it is preferred that the lifting drive member 14 is a scissor jack. The scissor jack can be operated by opening the box door 4.
When emergency needs to open two air doors at the same time, the lifting driving part 14 drives the sliding block 13 to ascend along the guide rail 12, so that the swinging frame 5 and the central rod 6 integrally move upwards, and at the moment, the two steel ropes 10 are both in a loose state, and the two air doors can be opened at the same time. When two air doors need to be closed simultaneously, the lifting driving part 14 drives the sliding block 13 to descend along the guide rail 12, so that the swinging frame 5 and the central rod 6 integrally move downwards, and at the moment, the second spiral springs 11 connected with the two steel ropes 10 are in a large stretching state, so that the second spiral springs 11 can apply a large pulling force to the door body 1 through the steel ropes 10, and the two air doors are locked simultaneously.
