For starting the closed type reductor of vertical lift closed guard gate's Flood gate
The present invention relates to a kind of lifting mechanism, the closed type for being particularly used to start vertical lift closed guard gate's Flood gate is slowed down
Machine, belong to crane gear field.
Existing Flood gate has following requirement to lifting mechanism：In case of emergency, can be incited somebody to action by long-range or live manipulation
Flood gate reliably turns off or on；, can be by Flood gate reliably by on-site manual manipulation in the case of urgent and dead electricity
Turn off or on.Therefore, the security reliability of Flood gate lifting mechanism is the key technology requirement of lifting mechanism.
Traditional water conservancy headstock gear has as a drawback that：
1, in the case of dead electricity, Flood gate can not be opened manually at the scene.
2, in the case of dead electricity, at the scene can manually operated emergency cut-off Flood gate, but manually operated cannot ensure
Flood gate closing process is steady, safe and reliable.
3, locking after Flood gate lifts or need by Flood gate locking braked by lifting motor for a long time, only together
Safety locking is protected, and a load occurs not having redundant safety protection device during special circumstances.
4, because decelerator is nonstandard decelerator, cost is higher.
Thus existing headstock gear can not fully meet requirement of the Flood gate to lifting mechanism.
The content of the invention
In order to solve the drawbacks described above of prior art, the present invention proposes to be prevented the present invention for starting vertical lift closed guard gate
The closed type reductor of door is flooded, to provide a kind of headstock gear that can safely, steadily open and close flood airtight blast door.
To achieve these goals, this invention takes following technical scheme：
For starting the closed type reductor of vertical lift closed guard gate's Flood gate, the lifting mechanism mainly by headstock gear and
Vertical jack up unit composition, the vertical jack up unit include two sets of hook gears and rope, and the headstock gear includes two sets of volumes
Wound packages is put, a nonstandard speed reducer used in hoisting, a raising braking motor, a synchronizing shaft；Two sets of roll devices include left-hand rotation wound packages
Put and right drum apparatus；The left and right ends of the synchronizing shaft connect a gear coupling respectively, and the gear coupling in left side is left
Side connects left drum apparatus, and the right side of the gear coupling on right side connects right drum apparatus by a nonstandard speed reducer used in hoisting,
The right-hand member of the right drum apparatus connects a raising braking motor；One is provided with the right side of the raising braking motor to release manually
Put device；An encoder is provided with the left of the left drum apparatus and is connected with an aperture load-weight measuring controlling instrument；It is described vertical
Jack up unit is arranged at the headstock gear top, and its rope is wound in the left drum apparatus and right drum apparatus, described
Hook gear includes the first fixed pulley seat, the second fixed pulley seat and boatswain chair pulley gear, the left drum apparatus and right-hand rotation
The rope that wound packages is put is connected after bypassing the first fixed pulley seat and the second fixed pulley seat successively upwards with boatswain chair pulley gear；Institute
Boatswain chair pulley gear bottom is stated to be connected with the flood airtight blast door.
Further, the left drum apparatus and right drum apparatus are arranged on base by bolt and backing plate.
Further, the raising braking motor is conical rotor motor.
Relative to prior art, the invention has the advantages that：
The present invention, as main raising, drives opposite side spool turns, so as to realize synchronization using 1 cucurbit by synchronizing shaft
Operation, it can be realized by electrical control and now and remotely be manipulated, this Scheme Characteristics is as follows：
1：Emergency opening can be realized in the case of having electricity and closes Flood gate.
2：In the absence of asynchronous problem.
3：Equipped with manual brake release, it can realize that on-site manual declutches to control and close Flood gate.
4：Rotary encoder can be installed in driven end, default Flood gate lifting altitude and scene can be achieved and distant place dynamic is seen
Examine Flood gate lifting altitude.
5：Occupy little space.

Fig. 2 is Fig. 1 side schematic view；
Fig. 3 is the headstock gear connection diagram in Fig. 1.
The present invention is further described with reference to embodiment.
As Figure 1-3, the of the invention closed type reductor for being used to start vertical lift closed guard gate's Flood gate, mainly by
Headstock gear and vertical jack up unit composition, vertical jack up unit includes two sets of hook gears and rope, as shown in figure 3, headstock gear
Including two sets of roll devices, nonstandard 4, raising braking motors 7 of speed reducer used in hoisting, a synchronizing shaft 2.Two sets of roll devices
Including left drum apparatus 1 and right drum apparatus 6.Raising braking motor 7 is conical rotor motor.The left and right two of synchronizing shaft 2
End connects a gear coupling 3 respectively, and the left side of gear coupling 3 in left side connects left drum apparatus 1, the gear coupling on right side
3 right side connects right drum apparatus 6 by a nonstandard speed reducer used in hoisting 4, and the right-hand member of the right drum apparatus 6 connects one and risen
Rise braking motor 7.The right side of raising braking motor 7 is provided with a hand release 8.The left side of left drum apparatus 1 is provided with
One encoder 12 is simultaneously connected with an aperture load-weight measuring controlling instrument 14.Vertical jack up unit is arranged at the headstock gear top, and it is restricted
Rope is wound in the left drum apparatus 1 and right drum apparatus 6, and hook gear includes the first fixed pulley seat 9, the second fixed pulley
Seat 10 and boatswain chair pulley gear 5, the rope in left drum apparatus 1 and right drum apparatus 6 are fixed sliding around first successively upwards
It is connected after the fixed pulley seat 10 of wheel seat 9 and second with boatswain chair pulley gear 5.The bottom of boatswain chair pulley gear 5 is protected with the flood
Sealed door connects.Left drum apparatus 1 and right drum apparatus 6 are arranged on base by bolt 13 and backing plate 11.
Above is the exemplary embodiments of the present invention, implementation not limited to this of the invention.
