On, by controlling hydraulic oil cylinder driving rope head component vertically along with movable rope head plate is moved, regulate the length of traction steel-cable
Spend and then move car, realizing safety flat bed the most again by the relative motion of car Yu traction steel-cable, effectively prevent
The flat bed that opens the door again produces and slips car, and on the machine room I-steel that is arranged in hoistway of this device, will not take cage top overhauling space,
And it is prone to the maintenance of this driving equipment；Additionally this device is away from car, does not affect the ride comfort of car.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of elevator fluid pressure type safety leveling device again, including position detecting device 1, level position magnetic grid
2, movable rope head plate 3, rope head component 4 and machine room I-steel 5, machine room I-steel 5 is fixed on machine room weighing unit 12, level position
Magnetic grid 2 is fixed in well enclosure and one piece every layer, movable rope head plate 3 is provided with switch frame 6, switch frame 6 is provided with
Portion's switch 61 and lower switches 62, machine room I-steel side connects has the switch matched with upper switches and lower switches to hit plate
7, switch is hit plate and is fixed on machine room I-steel by L-type installing rack 11, described rope head component 4 through movable rope head plate and with work
Running rope head plate is fixing to be connected, and machine room I-steel is provided with flat bed adjusting means again, and the described adjusting means of flat bed again is by hydraulic control
System 8, hydraulic power unit system 9 and two oil cylinders 10 are constituted, two oil cylinder 10 upper piston bars respectively with movable rope head plate two ends
Portion is fixing to be connected, and two oil cylinder lower cylinders are fixed with machine room I-steel respectively and are connected, hydraulic control system and position detection dress
Putting connection, hydraulic power unit system 9 is connected with two oil cylinders, hydraulic control systems respectively by oil pipe, two oil cylinder synchronization actions.
During use, elevator fluid pressure type safety leveling device again is wanted to realize flat bed again after each elevator runs flat bed, it is necessary to
Two operating conditions are divided to realize.1, the reset of elevator fluid pressure type safety leveling device again；2, elevator fluid pressure type safety flat bed again
Device flat bed again.
1, the reset of elevator fluid pressure type safety leveling device again
Flat bed again can be realized in order to ensure elevator fluid pressure type safety leveling device again after each elevator runs flat bed, close at elevator
The manipulation of elevator fluid pressure type the to be synchronously completed safety reset movable rope head plate of leveling device the most again in door, startup, running.Electricity
Ladder is closed the door, is started, run signal sends into hydraulic control system, and hydraulic control system is according to upper switches, lower switches simultaneously
Switching situation, controls hydraulic power unit system and drives cylinder efficient, adjust the height of movable rope head plate, completes to reset.Reset behaviour
Three kinds of situations of work point:
A: lower switches is connected, the disconnection of upper switches
This situation makes hydraulic control system control hydraulic power unit system to drive cylinder efficient, makes oil cylinder increase, movable fag end
Plate raises, and the distance that upper switches hits plate with switch moves closer to, until switch hits plate and pushes down upper switches, makes upper switches connect
Logical, lower switches remains switched on simultaneously, after hydraulic control system obtains the signal that two switches are also turned on, controls hydraulic pressure immediately
Pumping station system stops driving oil cylinder to rise, and completes the reset operation of movable rope head plate.
B: lower switches disconnects, the connection of upper switches
This situation makes hydraulic control system control hydraulic power unit system to drive cylinder efficient, makes oil cylinder decline, movable fag end
Plate falls, and the distance that lower switches hits plate with switch moves closer to, until switch hits plate and pushes down lower switches, makes lower switches connect
Logical, upper switches remains switched on simultaneously, after hydraulic control system obtains the signal that two switches are also turned on, controls hydraulic pressure immediately
Pumping station system stops driving oil cylinder to decline, and completes the reset operation of movable rope head plate.
C: lower switches is connected, the connection of upper switches
This situation makes hydraulic control system obtain two switches and is also turned on signal, and the reset operation of movable rope head plate completes.
2, elevator fluid pressure type safety leveling device flat bed more again
After elevator runs and arrives at a station and stop ladder, flat bed, enabling, owing to passenger passes in and out car, causing loading capacity change in sedan-chair, car carries
Heavily change makes traction steel-cable elastic elongation or shortening, thus causes not flat bed.Loading capacity reduces shifting on car, and loading capacity increases
Car moves down.Flat bed again is described in two kinds of situation for this: the upper deviation not flat bed and lower deviation not flat bed, i.e. car is put down the most again
Layer and car flat bed the most again.
The flat bed again of A: the upper deviation not flat bed
The weight (such as passenger leaves in sedan-chair) loaded in car, makes traction steel-cable shorten, passes through traction steel-cable
Effect car is moved up, the elevator generation Heisei deviation that original flat bed, cut gate exceed lading door dill one away from
From, at this moment lift car leveling sensed position detection device, to being fixed on the detection of the magnetic grid of each layer position in hoistway, obtain car one
The signal of the flat bed upper deviation, delivers to hydraulic control system by cable, controls hydraulic power unit after hydraulic control system computing
System, drives oil cylinder to decline, and reduces the height of movable rope head plate, and at this moment lift car leveling sensed position detection device is solid by detection
In hoistway, the magnetic grid of level position obtains car when being in flat bed state, just sends flat bed again and again to hydraulic control system
Signal, hydraulic control system controls hydraulic power unit system immediately and stops driving oil cylinder to decline, thus realizes car flat bed the most again.
The flat bed again of B: lower deviation not flat bed
The weight loaded in car becomes weight (in such as passenger enters sedan-chair), makes traction steel-cable extend, by traction steel-cable
Effect car is moved down, the elevator generation Heisei deviation that original flat bed, cut gate wall lading door dill low next away from
From, at this moment lift car leveling sensed position detection device, to being fixed on the detection of the magnetic grid of each layer position in hoistway, obtain car one
The signal of flat bed lower deviation, delivers to hydraulic control system by cable, controls hydraulic power unit after hydraulic control system computing
System, drives oil cylinder to rise, and raises the height of movable rope head plate, and at this moment lift car leveling sensed position detection device is solid by detection
In hoistway, the magnetic grid of level position obtains car when being in flat bed state, just sends flat bed again and again to hydraulic control system
Signal, hydraulic control system controls hydraulic power unit system immediately and stops driving oil cylinder to rise, thus realizes car flat bed the most again.
