Further, said encoder is installed on the said output shaft of said reductor.
Further, detect the revolution of two said the above output shafts of reductor respectively, go out the rotation distance of two said sprocket wheels through the control system-computed through described two encoders.
Further, the travel distance at described synchronous control system real-time more said fire door two ends in said fire door lifting process, and control its difference in allowed band.
Further, described lifting motor adopts frequency control, and after said fire door two ends surpassed allowed band apart from difference, the control system was through the output speed of frequency converter real-time regulated motor and said reductor.
The principle of the utility model is following: the Dual-motors Driving fire door hoisting mechanism of Synchronization Control is by the reductor of two translators, two reductor erection supports, two output shafts, two encoders, two cover fire door hoisting frames and two cover sprocket wheel and chain drive parts; Two reductors are installed respectively on two bearings, and they lay respectively at the furnace roof both sides of fire door top; By the motor-driven reductor, at the output axle head of reductor sprocket wheel is installed, sprocket wheel is supported by hoisting frame; Sprocket wheel chain above the drive sprocket wheel under the driving of reductor and then rotates simultaneously; The two ends of chain all are installed on the fire door, form endless loop with fire door, thereby realize the rising and the decline of fire door; Two encoders are installed in respectively on the output shaft of two reductors, write down the displacement of wing furnace door separately; Compare through the displacement of synchronous control system both; The difference of two values of assurance in allowed limits; The travel distance at fire door two ends is also compared in the final smooth and easy lifting that realizes fire door, synchronous control system in real time in the fire door lifting process, and controls its difference in allowed band.
Wherein the model of reductor, reductor erection support, output shaft, hoisting frame, sprocket wheel and the chain drive part of the two cover translators that hoisting mechanism comprised or structure need identical.The Dual-motors Driving fire door hoisting mechanism of Synchronization Control detects the revolution of the output shaft of two reductors respectively through two encoders; Go out the rotation distance of two sprocket wheels through the control system-computed; Promote motor and adopt frequency control; After the fire door two ends surpassed allowed band apart from difference, the control system was through the output speed of frequency converter real-time regulated motor and reductor.

The specific embodiment
Below with reference to accompanying drawing and combine embodiment, specify the utility model.
Referring to shown in Figure 1, a kind of Dual-motors Driving fire door hoisting mechanism of Synchronization Control is constituted and is that the synchronous control system of core is formed with encoder 7 by the identical and relatively independent hoisting mechanism of two covers; Described two cover hoisting mechanisms all independently comprise the reductor 1 of a translator, and said reductor 1 is installed on the bearing 2, connects through bolt, is easy for installation and removal, and said bearing 2 direct and furnace roof shaped steel welding guarantee weld strength during welding; Be provided with an output shaft 3 in the said reductor 1, said encoder 7 is installed on the said output shaft 3, during installation encoder 7 the axle will with output shaft 3 concentrics; The said output shaft 3 inboard sprocket wheels 5 that connect; Said sprocket wheel 5 is supported by the hoisting frame 4 that is installed on the said bearing 2; Said sprocket wheel 5 and then rotates at the chain drive part 6 that drives under the driving of said reductor 1 on the said sprocket wheel 5 simultaneously, and said chain drive part 6 connects fire door 8 both sides.
Further, the model of all component of said two cover hoisting mechanisms or structure need identical.
Further, the hoisting mechanism of both sides structurally is to oppose relatively.In order to guarantee that the both sides hoisting mechanism keeps synchronously the hoisting velocity of fire door both sides; Stuck phenomenon does not appear; The system that then need control compares encoder 7 recorded data in the hoisting mechanism of both sides in real time, and both displacement differences are limited in the scope of a permission.When the hoisting velocity of a side wherein is too fast, synchro system will be sent instruction and let its wait other end that underspeeds.Thereby stable, smoothness that realizes that fire door promotes and safety.
