Specific implementation mode
The utility model is further described with reference to the accompanying drawings and detailed description.
As shown in Fig. 1 to Fig. 7, a kind of damping machine, including
Main engine bed 1, the main engine bed are equipped with spool 2, hydraulic motor 3 and the driving motor 4 for driving spool,
Hydraulic motor includes motor shaft, fuel tank 31 and fluid pressure line, and driving motor includes machine shaft 41, and motor shaft turns with motor
Axis connection；
The fluid pressure line includes first throttle valve 321, second throttle 322 and solenoid directional control valve 323, solenoid directional control valve
With valve import, energization liquid outlet and dead electricity liquid outlet, fuel tank is equipped with oil inlet end and oil outlet end, and hydraulic motor further includes being used for
Hydraulic oil is delivered to the hydraulic pump of oil inlet end from oil outlet end；
When energization, valve import is connected to energization liquid outlet, and valve import and dead electricity liquid outlet disconnect, when dead electricity, valve import with
Dead electricity liquid outlet is connected to, and valve import is disconnected with energization liquid outlet；
The valve import is connected to oil outlet end, and energization liquid outlet is connected to oil inlet end, dead electricity liquid outlet and first throttle valve
Inlet communication, first throttle valve outlet are connected to oil inlet end, dead electricity liquid outlet and second throttle inlet communication, second throttle
Outlet is connected to by an idler wheel reversal valve 325 with oil inlet end；
The main engine bed is equipped with switching mechanism, and switching mechanism includes screw rodb base 51, the switch with screw rodb base rotation connection
Lead screw 52 and the sliding block 53 coordinated with switch wire rod thread, sliding block is slidably matched with main engine bed, and sliding is equipped with idler wheel pressing plate 54；
The spool is equipped with the drive sprocket 61 coaxially connected with spool, and switch lead screw is equipped with and switch lead screw
Coaxially connected driven sprocket 62, the transmission chain that a head and the tail are closed cross drive sprocket and driven sprocket around 63.
It is wound on spool for hanging the cable wire for drawing fireproof curtain.When a fire, cut off the power (or because fire is led
Cause equipment dead electricity), under self gravitation effect (at this time driving motor no longer or the power of pull-up fireproof curtain can not be provided), fire prevention
Curtain starts to fall.At the beginning, the falling speed of fireproof curtain is faster, can so ensure and quickly carry out between the scene of a fire and the external world
Flue gas isolation, after fireproof curtain declines a distance (such as close to after ground 2-3 meters), flue gas isolation effect tentatively reaches
At (flue gas uplink, so fireproof curtain already has stronger preliminary isolation effect after declining a distance).Fireproof curtain falls
When, drive spool, driving gear, machine shaft, motor shaft rotation, driving gear to drive driven gear rotation, driven tooth
Wheel drives switch lead screw rotation, and to which sliding block is moved with idler wheel pressing plate towards first throttle valve, idler wheel pressing plate not yet connects at this time
Touch idler wheel reversal valve.As was noted, after fireproof curtain declines a distance (such as close to after ground 2-3 meters), flue gas isolation effect
Fruit is tentatively reached, and idler wheel pressing plate comes into contact with the idler wheel reversal valve being connected to second throttle, idler wheel commutation at this time
Oil circuit where valve is eventually cut, thus, which the hydraulic oil reduced velocity flow in fluid pressure line, turns to the motor of hydraulic motor
Rotating speed reduces, since spool and motor shaft rotate together, so spool rotation slows down, to which fireproof curtain starts
It slows down, can so extend the escape time of performer (performer can flee between fireproof curtain lower end and stage).
The fluid pressure line further includes third throttle valve 324, dead electricity liquid outlet and third throttle valve inlet communication, third section
Stream valve outlet is connected to by an idler wheel reversal valve with oil inlet end.
The reduction of speed of fireproof curtain hereinbefore is known as a reduction of speed, and similarly, the presence of third throttle valve can carry out fireproof curtain
Secondary reduction of speed, in a reduction of speed, when fireproof curtain drops to soon close to stage (such as apart from stage 0.5 meter when), idler wheel
Pressing plate comes into contact with the idler wheel reversal valve being connected to third throttle valve, and oil circuit where the idler wheel reversal valve is eventually cut, such as
This one, the hydraulic pressure oil flow rate in the fluid pressure line of hydraulic motor further slows down, to the motor shaft rotating speed of hydraulic motor
Further slack-off, fireproof curtain further carries out slow drop, can extend the escape time of performer again.
It is upward in switch screw axis：Driven sprocket, switch lead screw, first throttle valve, second throttle and third throttle valve
It is sequentially arranged.
The spool is arranged by spool stand 21 on main engine bed, and spool stand is fixed with main engine bed, spool and host
Frame is rotatablely connected, spool axis horizontal.
Described machine shaft one end is coaxially connected by shaft coupling 7 with motor shaft one end.Machine shaft and motor shaft
It is convenient to install and dismantle, and is conducive to safeguard, replace.
Further include a speed reducer 8, the input terminal connection of the machine shaft other end and speed reducer, the output end of speed reducer and master
Movable sprocket is coaxially connected.Using speed reducer, can reasonable rate controlling effectively be carried out to spool.
The fluid pressure line further includes overflow valve 326, and overflow valve import is connected to dead electricity liquid outlet, overflow valve outlet with into
Oily end connection.When instantaneous oil pressure is excessive in fluid pressure line, overflow valve can adaptively carry out opening pressure release, and pipeline is avoided to damage
It is bad.
The idler wheel pressing plate has the pre- pressure surface 54a for contact roller reversal valve and connecing for contact roller reversal valve
Contacting surface 54b, pre- pressure surface are connect with contact surface, and contact surface is horizontally disposed, at 20 to 70 degree angles 325 between pre- pressure surface and contact surface.
Pre- pressure surface can carry out precompressed to idler wheel reversal valve, avoid idler wheel reversal valve from being pressurized quickly excessive, excessive by impacting, to
The ride comfort of handoff procedure can be improved and ensure the service life of each dependency structure.
The main engine bed is equipped at least one auxiliary sprocket wheel 64, auxiliary sprocket wheel and main engine bed rotation connection, transmission chain around
Cross all auxiliary sprocket wheels.Auxiliary sprocket wheel can promote tension effects, improve the stability in the entire sprocket system course of work.
