The fluid pressure type of elevator shown in Fig. 1 safety again leveling device determine be provided with guide piece 7 between rope hitch plate 2 and movable rope hitch plate 11.
The safe leveling device again of the fluid pressure type of elevator shown in Fig. 2 unloads power spring 16 and is enclosed within guide piece 7.
The safe leveling device again of the fluid pressure type of elevator shown in Fig. 1 unloads power spring 16 and is enclosed within tapered sleeve group system 10.
The safe leveling device again of the fluid pressure type of elevator shown in Fig. 2 unloads power spring 16 and is enclosed within oil cylinder 8.
Elevator fluid pressure type safety again leveling device is wanted to realize flat energy after each elevator runs flat bed again, and two operating conditions must be divided to realize.1, the reset of the safe leveling device again of elevator fluid pressure type; 2, elevator fluid pressure type safety leveling device flat bed more again.
1, the reset of the safe leveling device again of elevator fluid pressure type
In order to ensure elevator fluid pressure type safety again leveling device can realize more flat energy after each elevator runs flat bed, the operation of the elevator fluid pressure type 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 hydraulic control system 3, hydraulic control system 3 is simultaneously according to the on off mode of lower switches 12, upper switches 15, hydraulic control pumping station system 6 drives oil cylinder 8 to work, adjustment activity rope hitch plate 11 and the spacing of determining between rope hitch plate 2, complete the operation set back, namely movable rope hitch plate 11 resets.Reset operation divides three kinds of situations:
A: lower switches 12 is connected, the disconnection of upper switches 15
The first situation A makes hydraulic control system 3 hydraulic control pumping station system 6 work to drive oil cylinder 8, oil cylinder 8 is made to increase, unload power spring 16 to extend, determine rope hitch plate 2 to increase gradually with the spacing of movable rope hitch plate 11, the distance that upper switches 15 and switch hit plate 13 moves closer to, until switch hits plate 13 push down upper switches 15, upper switches 15 is connected, lower switches 12 still keeps connecting simultaneously.After hydraulic control system 3 obtains the signal that two switches connect simultaneously, hydraulic control pumping station system 6 stops driving oil cylinder 8 to rise immediately, completes the reset operation of movable rope hitch plate 11.
B: lower switches 12 disconnects, the connection of upper switches 15
The second situation B makes hydraulic control system 3 hydraulic control pumping station system 6 work to drive oil cylinder 8, oil cylinder 8 is declined, unload power spring 16 to compress, determine rope hitch plate 2 to reduce gradually with the spacing of movable rope hitch plate 11, the distance that lower switches 12 and switch hit plate 13 moves closer to, until switch hits plate 13 push down lower switches 12, lower switches 12 is connected, upper switches 15 still keeps connecting simultaneously.After hydraulic control system 3 obtains the signal that two switches connect simultaneously, hydraulic control pumping station system 6 stops driving oil cylinder 8 to decline immediately, completes the reset operation of movable rope hitch plate 11.
C: lower switches 12 is connected, the connection of upper switches 15
The third situation C makes hydraulic control system 3 obtain two switches connection signal simultaneously, and not affected any further operation, the reset operation of movable rope hitch plate 11 completes.
2, the flat bed again of the safe leveling device again of elevator fluid pressure type
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 10, 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 4, to the detection of magnetic grid 5 of being fixed on each layer level position in hoistway, obtain the signal of car one flat bed upper limit of variation, hydraulic control system 3 is delivered to by cable, hydraulic control pumping station system 6 after hydraulic control system 3 computing, drive oil cylinder 8 to decline, power spring 16 is unloaded in compression, determine rope hitch plate 2 to reduce gradually with the spacing of movable fag end 11, finally reduce distance.At this moment lift car leveling sensed position detecting device 4, obtain car be in flat bed state by detecting the magnetic grid 5 being fixed on level position in hoistway, send flat bed signal again and again just to hydraulic control system 3, hydraulic control system 3 immediately hydraulic control pumping station system 6 stops driving oil cylinder 8, 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 10, 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 4, to the detection of magnetic grid 5 of being fixed on each layer level position in hoistway, obtain the signal of car one flat bed lower deviation, hydraulic control system 3 is delivered to by cable, hydraulic control pumping station system 6 after hydraulic control system 3 computing, drives oil cylinder 8 to rise, unloads power spring 16 and extend, determine rope hitch plate 2 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 4, obtain car be in flat bed state by detecting the magnetic grid 5 being fixed on level position in hoistway, send flat bed signal again and again just to hydraulic control system 3, hydraulic control system 3 immediately hydraulic control pumping station system 6 stops driving oil cylinder 8, thus realizes car down flat bed again.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
