Specific embodiment
Embodiment 1: as shown in Figure 1 and 2, a kind of exhaust outlet headstock gear, including the installation being mounted on 1 wall of exhaust outlet
Seat 2, mounting base 2 are greater than exhaust outlet 1, are equipped with mounting groove 201 on the inside of mounting base 2, sealing plate 3, which slides up and down, is mounted on mounting groove
In 201, traction rope 4 is connected on the upside of sealing plate 3, traction rope 4 connect around fixed pulley 5 with power device 6, and fixed pulley 6 is set as
Two, the surface of sealing plate 3 is arranged in one of them, another is arranged in the surface of power device 6, traction rope 4 according to
It is secondary bypass two fixed pulleys 6 after connect with power device 6, sealing plate 3 is risen or is fallen by traction rope 4 by power device 6.
Power device 6 can be set to hoist engine, and traction rope 4 is wrapped on hoist engine.
Sealing plate 3 is fire-resistant gypsum panel.It can also play the role of fireproof while sealing, it is logical to can be used for fire-fighting
Road.
The mounting base 2 is the "U" shaped of upward opening.Facilitate sliding up and down for sealing plate 3.
Preferably, as shown in Fig. 3 ~ 4, the mounting base 2 is " mouth " font, is equipped on the upside of mounting base 2 and passes through for sealing plate 3
Through slot 202.Mounting base 2 is set as " mouth " font compared to "U" shaped, and sealing effect is more preferable.
201 inner wall of mounting groove is equipped with sealing strip 8, and the sealing effect of sealing plate 3 can be improved.
Embodiment 2: different from embodiment 1,3 two sides of sealing plate are equipped with gag lever post 7, and 2 two sides of mounting base, which are equipped with, to be supplied
The sliding slot 203 that gag lever post 7 passes through.
It cannot be continued to move up when gag lever post 7 is moved to 203 top of sliding slot, so as to prevent sealing plate 3 from moving
Out mounting base 2 and cause sealing plate 3 to be unable to normal switching-off.
The power device 6 includes ratchet 601 and wire spool 602, and ratchet 601 and wire spool 602 are coaxially connected, traction rope
