Perfect day by day along with domestic venue and commercial building just progressively pursued the mode of large tracts of land and full open even 100m to the skylight that is used for hedging and smoke evacuation
2The existing utilization in a fan skylight.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the sliding fire-fighting electric window-opening machine of favorable working performance.
Technical solution of the present utility model is:
A kind of sliding fire-fighting electric window-opening machine, it is characterized in that: comprise motor-driven reducer, reducer output shaft is connected with the power shaft of damper, reducer output shaft is connected with the drive unit that drives skylight or roof mechanism for opening/closing work, and electromotor brake is connected with the dead electricity releasing device of control electromotor brake work.
Damper is a hydraulic damper.
The dead electricity releasing device is the manual drag-line mechanism that is connected with electromotor brake.
The dead electricity releasing device comprises the drag-line that is connected with electromotor brake, drag-line is drawn downwards by transition wheel, drag-line position assembling pouring weight or spring below transition wheel, balancing weight or spring top are connected with the lower end of hot melt sheet, and the upper end of hot melt sheet is connected with the fixture of its top.
The utility model is rational in infrastructure, can be widely used in the skylight or the roof of larger area slippage, in daily use, brake gets electric release, guarantee the without hindrance power drive of motor, damper gets electric electromagnetic valve and opens, and guarantees that the motor undamped drives, and can realize the various functions of use of the daily ventilation on slippage skylight or roof; Can realize fire-fighting smoke evacuation function with the interlock of fire-fighting center under the fire fighting state.Under power failure state, but manual releasing is opened, in the time of also can working as room temperature and reach 70 ℃, the fusing of hot melt sheet, balancing weight draws back brake, and skylight or roof utilize own wt to open automatically downwards, and, in dead electricity slippage opening process, hydraulic damper possesses three step velocity dampings, has avoided equipment inertia and impact effectively.
Function of the present utility model is: the electronic keying of (1) daily ventilation; (2) and fire-fighting center interlock electrically opened smoke-discharging; (3) the utility model slippage skylight area big (single hole can be to 10m * 10m), dead electricity or all circuit burn or electronic part is malfunctioning or during fault, still can utilize skylight own wt slippage to open rapidly, be beneficial under the fire-fighting smoke evacuation and the state of emergency and sue and labour; (4) because of the utility model mainly applies to large-scale femerell, must avoid motional inertia and impact force,, when dead electricity, make skylight safety slide unlatching so use the hydraulic damper three-stage damping.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the configuration diagram of hydraulic damper.
The specific embodiment:
A kind of sliding fire-fighting electric window-opening machine, comprise the reducer 2 that motor 1 drives, reducer output shaft is connected with the power shaft 4 (the damper power shaft is a screw shaft) of hydraulic damper 13 by shaft coupling 3, reducer output shaft is connected with the drive unit 5 that drives skylight or roof mechanism for opening/closing work, and electromotor brake 6 is connected with the dead electricity releasing device of control electromotor brake work.
The dead electricity releasing device comprises the drag-line 7 that is connected with electromotor brake, drag-line is drawn downwards by transition wheel 8, drag-line position assembling pouring weight (or spring) 9 below transition wheel, balancing weight or spring top are connected with the lower end of hot melt sheet 10, and the upper end of hot melt sheet is connected with the fixture 11 (can directly adopt transition wheel 8) of its top.Under the state of emergency of dead electricity, can manually draw back brake; And when interior temperature reaches 70 ℃, the fusing of hot melt sheet, balancing weight (or spring) pulling cable wire draws back brake.
(or cylinder body is outer) uniform 2-4 root hollow conduit that is fixed with in the cylinder body of damper, the piston that screw shaft is arranged and be engaged with, radially be shaped on oilhole and damping hole on the conduit, the adjusting of carrying out damping hole turnover oil mass be pass through be arranged on the outer unidirectional control valve of oil cylinder.Wherein the hollow conduit of big flow is installed electromagnetic valve, electromagnetic valve is opened under situation that must be electric, the motion of piston is subjected to the minimum of damping, the driving force of motor reducer is not influenced by damping substantially, during dead electricity, closed electromagnetic valve, starting was quickened when the flow field that passes through by other control valve of setting hollow conduit in advance can make the skylight emergency opening, the centre at the uniform velocity, the three-stage damping effect of slowing down in the end.
Also has casing 12 among the figure.
In daily ventilation state, brake gets electric release and guarantees the without hindrance power drive of motor, and the damper electromagnetic valve gets the electric oil circuit of opening, and damper does not play damping action substantially.Drive output chain gear and drive the driven wheel motion that is located at slippage skylight or below, roof, gear driven tooth bar, tooth bar are attached to skylight or roof.Whole skylight or roof are done daily ventilation use and are opened or close, when the fire-fighting signal is sent at the fire-fighting center, and the response of fire-fighting electric window-opening machine, the electronic skylight is opened at utmost discharged fume.
In power failure state, the locking of brake dead electricity is guaranteed the skylight off-position accurately and reliably, avoids unnecessary accident to slide and causes device damage.
During fire fighting state, because under the situation of dead electricity or electronic partial fault or circuit burnout, the fire-fighting smoke-discharge skylight does not move, the finder can manually spur cable wire, and cable wire draws back brake, and the skylight utilizes the downward slippage of own wt to open.When room temperature arrives 70 ℃, the fusing of hot melt sheet, balancing weight draws back brake, and the skylight utilizes the downward slippage of own wt to open.Reach the functional requirement of manual releasing under the state of emergency and the automatic passive unlatching of 70 degree hot melts.
At this moment, hydraulic damper electromagnetic valve dead electricity is closed, and the axle of motor reducer drives the rotation of damper screw shaft by shaft coupling, and the piston that meshes with the screw shaft machine moves in the damper oil cylinder.The fluid in piston the place ahead rearward moves by oilhole and the damping hole that is shaped on the hollow conduit in the uniform cylinder, allow piston by the oilhole of each position of conduit and the oil mass size of damping hole by the unidirectional control valve that sets in advance, realize the starting acceleration, middle average rate, the damped motion that final stage is slowed down, guarantee that the skylight utilizes the downward slippage of own wt slowly to stop rapidly putting in place, avoids impact force and inertia.Guarantee the safety of equipment and building.
