Specific embodiment
A kind of mine ventilation control system in conjunction with shown in Fig. 1-5, including the twice wind being successively set in mine laneway
Door and the linkage fastener being arranged between twice air door, the linkage fastener open one for realizing the one of twice air door
It closes, twice air door is avoided to open simultaneously.The door body 1 of the twice air door and the hinged side of doorframe 2 are respectively positioned on the same side, such as Fig. 1
It is shown, that is to say, that the doorframe 2 of twice air door is right side with the hinged side of door body 1, then active side is left side；Or hingedly side is equal
For left side, active side is right side.The linkage fastener includes the installs case and setting being fixed on the side wall of tunnel
Linkage lock mechanism in installs case.The installs case is made of cabinet 3 and setting in the positive flat-open type chamber door 4 of cabinet 3,
The setting of chamber door 4 can be convenient for the maintenance and maintenance to linkage blocking mechanism.
As shown in figure 3, the linkage lock mechanism includes that prolonging along 3 width direction of cabinet for middle and lower part in cabinet 3 is arranged in
The swinging frame 5 stretched and the central axis 6 extended along 3 thickness direction of cabinet, the middle part of the swinging frame 5 are arranged connecting hole, it is described in
Mandrel 6 is threaded through in connecting hole and constitutes hingedly with swinging frame 5.After swinging frame 5 and central axis 6 are hinged, swinging frame 5 can be in
Mandrel 6 is rotated, and simplest swinging frame 5 is exactly an oscillating rod, and the middle part of oscillating rod and central axis 6 are hinged.
First cord hole 8 is respectively arranged on the two sidewalls on 3 top of cabinet, cabinet 3 is interior opposite with the first cord hole 8
Position be provided with the first directive wheel 9.The linkage lock mechanism further includes two steel cables 10, one end difference of the steel cable 10
It is connect by second helical spring 11 with the both ends of swinging frame 5, the other end successively passes through the first directive wheel 9 and the first cord hole
It is connect after 8 with the door body 1 of twice air door.In order to enable steel cable 10 has sufficiently large pulling force to door body 1, better way is,
The door body 1 and the junction of steel cable 10 are located at top of the door body 1 far from hinged side, that is, the connection of door body 1 and steel cable 10
Place is located at the top of 1 active side of door body.Meanwhile in order to improve the stability of steel cable 10, in conjunction with shown in Fig. 1 and 4, the doorframe 2
The second cord hole 15 is arranged in the position opposite with the movable upper lateral part of door body 1, and the second directive wheel 16, institute is arranged in second cord hole 15
It states steel cable 10 and is connect with the pull ring 17 being fixed on 1 outer surface of door body.Swinging frame 5 is because self weight is in normal state
Horizontality.Detachable mandril 30 is arranged between 3 top surface in the sliding shoe 13 and cabinet.
Working principle of the present invention is as follows: in normal state, twice air door is turned off, and swinging frame 5 is in level at this time
State.When needing to open one of air door, door body 1 is pulled, door body 1 drives steel cable 10, and mandril 30 maintains 13 position of sliding shoe solid
Fixed, so steel cable 10 drives swinging frame 5 to rotate, swinging frame 5 is close to one end tilting, the other end bottom for opening air door；Pendulum
One end of 5 bottom of moving frame is by the corresponding steel cable 10 of another road air door and the second helical spring 11 with tight.Ensure that twice wind
Door is together in closing, the openable safe condition in another road.Meanwhile it is the configuration of the present invention is simple, easy to maintain, and without using electricity
Machine, cylinder etc. control air door, and safety is high.
It preferably improves, the bottom surface that the both ends of the swinging frame 5 pass through first helical spring 7 and cabinet 3 respectively connects
It connects.13 position of sliding shoe in this way is more stable, and detachable mandril 30 is also facilitated to install, and opens the door also more labor-saving.The guide rail 12 is right
Claim setting two, the detachable mandril 30 is between two guide rails 12.Sliding shoe 13 slides more stable, detachable mandril 30
It supports also more stable.
The specific embodiment of the detachable mandril 30 can be very much, e.g. air-cylinder type, and release air pressure can
To dismantle mandril 30, reaching both sides while enabling carries out the operation such as debugging, normality lower cylinder is with pressure, 13 position of position sliding shoe,
Ensure that only side can open the door.For detachable mandril 30 for example including the body of rod, the body of rod is provided with external screw thread on one end, and is adapted to
Wing nut 31；Shallow recess portion, detachable 30 end face of the mandril position is arranged in the sliding shoe 13 or 3 top surface corresponding position of cabinet
In in recess portion, wing nut 31 is located in plane.More preferably there is shallow recess portion at both ends, it is ensured that detachable mandril 30 has certain shake
It is dynamic to shift.
Since swinging frame 5 is core of the invention stressed member, in order to further increase the stability of the movement of swinging frame 5,
Better way is that, as shown in figure 5, the swinging frame 5 is rectangle frame-shaped, the both ends of swinging frame 5 are respectively arranged with connection sheet
18, the upper and lower surfaces of the connection sheet 18 are respectively arranged with connection ring 19, and the swinging frame 5 passes through connection ring 19 and the
One helical spring 7 and the connection of the second helical spring 11；The middle part of the swinging frame 5 is fixedly installed short sleeve in the width direction
20, the connecting hole is the pore of short sleeve 20；Position-arresting disk 21 there are two being also set up on the central axis 6, and two position-arresting disks
The distance between 21 match with the width of swinging frame 5.Swinging frame 5 in this way, enable to its swing when not
It is slided on central axis 6, and the stability of swinging frame 5 itself is more preferable, the service life is longer.
Since the environment in mine is complicated, generally require to open simultaneously twice air door when having the condition of a disaster and dangerous situation or
It simultaneously closes off, for this purpose, as shown in figure 3, be additionally provided with vertical guide rail 12 on the inner wall at 3 back side of cabinet of the present invention, and
Sliding shoe 13 is fitted on guide rail 12, the central axis 6 is fixed on sliding shoe 13, and the sliding shoe 13 is by being fixedly installed
3 bottom of cabinet lifting driver part 14 drive, lifting driver part 14 for drive sliding block 13 on guide rail 12 on move down
Dynamic, commonly such as: cylinder, linear electric machine, but in view of charging equipment is in the risk of underground work, better way be,
The lifting driver part 14 is exactly a scissor-type jack.Scissor-type jack can be operated by opening chamber door 4.
When an emergency situation is encountered, needs to open simultaneously twice air door, lifting driver part 14 drive sliding shoe 13 along
Guide rail 12 rises, so that swinging frame 5 and 6 entirety of central axis be made to move up, two steel cables 10 are in loose state at this time, can be real
Existing twice air door opens simultaneously.When needing to simultaneously close off twice air door, lifting driver part 14 drives sliding shoe 13 along leading
Rail 12 declines, so that swinging frame 5 and 6 entirety of central axis are moved down, the second helical spring 11 being connect at this time with two steel cables 10
It is in biggish tensional state, therefore the second helical spring 11 can apply a biggish pulling force to door body 1 by steel cable 10,
Locking while to realize twice air door.
