It states lock shaft and is horizontally set on the door-plate plate face, left end extends left side doorframe and passes through with the locking cylinder being vertically arranged
Connecting lever connects；The doorframe upper transverse frame is fixed with guide rail, which, at least provided with two directive wheels, further includes connecting plate, described
Connecting plate lower end connects top surface on the door-plate, and upper end connects the directive wheel；The propulsion cylinder setting is on the door-plate right side
Side, telescopic rod end are connect with the door-plate right part.
Further, the lock shaft is arranged in the middle part of the door-plate.
Further, there are one the locking cylinders.
Further, the propulsion cylinder telescopic rod is detachably connected with the door-plate.
Further, further include connecting seat, the connecting seat is fixed in the propulsion cylinder telescopic rod end, and passes through spiral shell
Line connection is fixed in the door-plate right part.
Further, the directive wheel at least 4, and each two guide wheel group is at one group.
The advantageous effect that the utility model is compared with the prior art includes：Air door is directly connected using propulsion cylinder bar with door-plate
It connects, that is, ensures the safe and reliable operation of air door, and to transport, installation brings facility；By lock shaft assembly in the middle part of door-plate
It is on the upper side, using a locking cylinder can end of door plate locked, reduce production cost, repair it is more convenient；Two directive wheels
It forms one group, increases the contact area of directive wheel and guide rail bottom surface, it is stable to be that door-plate improves in moving process, avoids door
Plate shakes, the smooth working of effective protection propulsion cylinder.
Description of the drawings
Fig. 1 is the utility model main structure diagram；
Fig. 2 is the utility model side structure schematic view；
Fig. 3 is the utility model door-plate and directive wheel annexation figure.
Specific implementation mode
With reference to embodiment and compares attached drawing the utility model is described in further detail.It should be emphasized that
It is that following the description is only exemplary, rather than in order to limit the scope of the utility model and its application.
With reference to the following drawings, non-limiting and nonexcludability embodiment will be described, wherein identical reference numeral indicates
Identical component, unless stated otherwise.
Boiler milling system heat primary air door as shown in Figs. 1-2, including doorframe 1, door-plate 10, locking cylinder 7, lock shaft
13, connecting lever 12, propulsion cylinder 8,13 level of lock shaft are horizontally set with the position on the upper side at the middle part of 10 plate face of door-plate or middle part, lock shaft
Being equipped on 13 can be with the cam 4 of its synchronous rotation.The doorframe 1 of the left and right sides offers opposite location hole, lock shaft 13
Both ends are transferred on by bearing is rotatable in the location hole, and the both ends of lock shaft 13 extend.The left end of lock shaft 13
Extend left side doorframe 1 and is connect by connecting lever 12 with 7 telescopic rod end of locking cylinder for being vertically arranged in 1 left side of doorframe.Lock
Tight cylinder 7, connecting lever 12, lock shaft 13 form linkage mechanism, reaches and regulates and controls 1 end of door plate of cam by the flexible of locking cylinder 7
10 release and compression.The upper transverse frame of doorframe 1 is fixed with guide rail 6, is equipped with two groups of guide wheel groups in the guide rail 6, guide wheel group by
Two directive wheels 5 are connected as an entirety by a piece connecting rod, and directive wheel 5 is connected by top surface both ends on connecting plate 9 and door-plate 10
It connects, door-plate 10 is made to be in suspended state.Two directive wheels 5 form one group, increase the contact area of directive wheel 5 and 6 bottom surface of guide rail,
Improved in moving process for door-plate 10 it is stable, avoid door-plate 10 shake, the smooth working of effective protection propulsion cylinder 8.
