During use lift screw formula safety again leveling device want realize putting down energy again after each elevator runs flat bed, two operating conditions must be divided to realize.1, the reset of the safe leveling device again of lift screw formula; 2, lift screw formula safety leveling device flat bed more again.
1, the reset of the safe leveling device again of lift screw formula
In order to ensure lift screw formula safety again leveling device can realize more flat energy after each elevator runs flat bed, the operation of the lift screw formula reset activity rope hitch plate 11 of leveling device more safely of closing the door at elevator, start, will synchronously complete in operational process.Elevator is closed the door, start, run signal sends into electric control system 4, and electric control system 4 checks that the switching situation of lower switches 15, upper switches 16 is to carry out reset operation simultaneously.Reset operation divides three kinds of situations:
A: lower switches 15 is connected, the disconnection of upper switches 16
The first situation A makes electric control system 4 control motor opposite spin, through driving two speed reduction gearings 2 to synchronous working with the drive screw 1 of motor coaxle, drive adjusting screw(rod) 10 opposite spin, make to unload power spring 8 to extend, determine rope hitch plate 7 to increase gradually with the spacing of movable rope hitch plate 11, the distance that upper switches 16 and switch hit plate 14 moves closer to, until switch hits plate 14 push down upper switches 16, upper switches 16 is connected, and lower switches 15 still keeps connecting simultaneously.After electric control system 4 obtains the signal that two switches connect simultaneously, stop motor rotating immediately, complete the reset operation of movable rope hitch plate 11.
B: lower switches 15 disconnects, the connection of upper switches 16
The second situation B makes electric control system 4 control the rotation of motor positive dirction, through driving two speed reduction gearings 2 to synchronous working with the drive screw 1 of motor coaxle, adjusting screw(rod) 10 positive dirction is driven to rotate, make to unload power spring 8 to compress, determine rope hitch plate 7 to reduce gradually with the spacing of movable rope hitch plate 11, the distance that lower switches 15 and switch hit plate 14 moves closer to, until switch hits plate 14 push down lower switches 15, lower switches 15 is connected, and upper switches 16 still keeps connecting simultaneously.After electric control system 4 obtains the signal that two switches connect simultaneously, stop motor rotating immediately, complete the reset operation of movable rope hitch plate 11.
C: lower switches 15 is connected, the connection of upper switches 16
The third situation C makes electric control system 4 obtain two switches connection signal simultaneously, and the operation of movable rope hitch plate 11 completes.
2, lift screw formula safety leveling device flat bed more again
After elevator runs and arrives at a station and stop ladder, flat bed, enabling, because passenger passes in and out car, sedan-chair is caused to contain changes in weight.Car weight change makes traction steel-cable elastic elongation or shortening, thus causes not flat bed.Load carrying ability minimizing car moves; Load carrying ability increases car and moves down.For this point two kinds of situations illustrate flat bed again: the flat bed again of upper limit of variation not flat bed and lower deviation not flat bed, i.e. car down flat bed, car up flat bed more again.
A: upper limit of variation not flat bed flat bed again illustrate:
The weight (such as passenger leaves in sedan-chair) of loading in car, traction steel-cable is shortened, by the effect of steel rope, tapered sleeve group system 12, car is moved up, the elevator generation flat bed deviation that original flat bed, car door sill exceeds lading door dill one distance.At this moment lift car leveling sensed position detecting device 5, to the detection of magnetic grid 6 of being fixed on each layer level position in hoistway, obtain the signal of car one flat bed upper limit of variation, electric control system 4 is delivered to by cable, after electric control system computing, control motor positive dirction rotate, through making two speed reduction gearings 2 synchronous working with the drive screw 1 of motor coaxle, adjusting screw(rod) 10 positive dirction is driven to rotate, power spring 8 is unloaded in compression, determine rope hitch plate 7 to reduce gradually with the spacing of movable rope hitch plate 11, finally reduce distance.At this moment lift car leveling sensed position detecting device 5, obtain car be in flat bed state by detecting the magnetic grid 6 being fixed on level position in hoistway, send flat bed signal again and again just to electric control system 4, electric control system 4 stops motor rotating, thus realizes car down flat bed again.
B: lower deviation not flat bed flat bed again illustrate:
The weight of loading in car becomes heavy (such as passenger enters in sedan-chair), traction steel-cable is extended, by the effect of steel rope, tapered sleeve group system 12, car is moved down, the elevator generation flat bed deviation that original flat bed, car door sill next distance lower than lading door dill.At this moment lift car leveling sensed position detecting device 5, to the detection of magnetic grid 6 of being fixed on each layer level position in hoistway, obtain the signal of car one flat bed lower deviation, electric control system 4 is delivered to by cable, motor opposite spin is controlled after electric control system computing, through making two speed reduction gearings 2 synchronous working with the drive screw 1 of motor coaxle, drive adjusting screw(rod) 10 opposite spin, unload power spring 8 to extend, determine rope hitch plate 7 to increase gradually with the spacing of movable rope hitch plate 11, the distance finally increased.At this moment lift car leveling sensed position detecting device 5, obtain car be in flat bed state by detecting the magnetic grid 6 being fixed on level position in hoistway, send flat bed signal again and again just to electric control system 4, electric control system 4 stops motor rotating, thus realizes car up flat bed again.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
