Specific implementation mode
A kind of mine ventilation control system in conjunction with shown in Fig. 1-5, including the twice wind that is 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 is respectively positioned on the same side, such as Fig. 1 with the hinged side of doorframe 2
It is shown, that is to say, that it is right side that the doorframe 2 of twice air door is hinged side with 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 being fixed on the side wall of tunnel and setting
Linkage lock mechanism in installs case.The installs case is made of babinet 3 and setting in 3 positive flat-open type chamber door 4 of babinet,
The setting of chamber door 4 can be convenient for maintenance and maintenance to the blocking mechanism that links.
As shown in figure 3, the linkage lock mechanism includes that prolonging along 3 width direction of babinet for middle and lower part is arranged in babinet 3
Connecting hole is arranged in the middle part of the swing span 5 stretched and the center-pole 6 extended along 3 thickness direction of babinet, the swing span 5, in described
Core bar 6 is threaded through to constitute with swing span 5 in connecting hole and be hinged.After swing span 5 and center-pole 6 are hinged, swing span 5 can be in
Core bar 6 is rotated, and simplest swing span 5 is exactly an oscillating rod, and the middle part of oscillating rod and center-pole 6 are hinged.
The both ends of the swing span 5 are connect by first helical spring 7 with the bottom surface of babinet 3 respectively, in normal shape
State bottom moving frame 5 is in horizontality.First cord hole 8 there are one being respectively set on the two side on 3 top of the babinet, babinet 3
The interior position opposite with the first cord hole 8 is provided with the first directive wheel 9.The linkage lock mechanism further includes two steel cables 10, institute
The one end for stating steel cable 10 is connect by second helical spring 11 with the both ends of swing span 5 respectively, and the other end passes through the successively
It is connect with the door body 1 of twice air door after one directive wheel 9 and the first cord hole 8.In order to enable steel cable 10 to door body 1 have it is sufficiently large
Pulling force, better way are that the junction of the door body 1 and steel cable 10 is located at top of the door body 1 far from hinged side, that is, door
The junction of body 1 and steel cable 10 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 Fig. 1
Shown in 4, the second cord hole 15 is arranged in the position opposite with the movable upper lateral part of door body 1 of the doorframe 2, is set in second cord hole 15
The second directive wheel 16 is set, the steel cable 10 is connect with the draw ring 17 being fixed on 1 outer surface of door body.
Working principle of the present invention is as follows：In normal state, twice air door is turned off, and swing span 5 is in level at this time
State.When needing to open one of air door, door body 1, door body 1 is pulled to drive steel cable 10, steel cable 10 that swing span 5 is driven to revolve
Turn, swing span 5 is close to one end tilting, the other end bottom for opening air door；One end of 5 bottom of swing span corresponds to another road air door
Steel cable 10 and the second helical spring 11 with tight.Ensure that twice air door together in closing, the openable peace in another road
Total state.Meanwhile it is the configuration of the present invention is simple, easy to maintain, and air door is controlled without using motor, cylinder etc., safety
It is high.
Since swing span 5 is core of the invention stressed member, in order to further increase the stability of the action of swing span 5,
Better way is that, as shown in figure 5, the swing span 5 is rectangle frame-shaped, the both ends of swing span 5 are respectively arranged with connection sheet
18, the upper and lower surface of the connection sheet 18 is respectively arranged with connection ring 19, and the swing span 5 passes through connection ring 19 and
One helical spring 7 and the connection of the second helical spring 11；The middle part of the swing span 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 center-pole 6, and two position-arresting disks
The distance between 21 match with the width of swing span 5.Swing span 5 in this way, enable to its swing when not
It is slided on center-pole 6, and the stability of swing span 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 babinet of the present invention, and
Sliding shoe 13 is fitted on guide rail 12, the center-pole 6 is fixed on sliding shoe 13, and the sliding shoe 13 is by being fixedly installed
3 bottom of babinet lifting driver part 14 drive, lifting driver part 14 for drive sliding block 13 on guide rail 12 on move down
It is dynamic, commonly such as：Cylinder, linear electric machine etc., but in view of charging equipment is in the risk of underground work, better way is,
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, and to make swing span 5 and 6 entirety of center-pole 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, to make swing span 5 and 6 entirety of center-pole move down, the second helical spring 11 being connect at this time with two steel cables 10
It is in larger tensional state, therefore the second helical spring 11 can apply a larger pulling force by steel cable 10 to door body 1,
It is latched while twice air door to realize.
