In the front portion of plate 45, be provided with a pair of optical pickocff 48a and 48b and be used as position detecting device, it is along groove 46 vertical arrangements.The position of the position of position probing bar 44 or locating dowel pin 37 is detected by these optical pickocffs 48a and 48b.
The suspension 11a and the 11b that are arranged on each door-plate 4a and the 4b have positioning plate 50a and 50b respectively.These positioning plates 50a and 50b are preceding side-prominent towards passenger cabin 1, and are arranged on the position that differs from one another along vertical direction.
In off position down, the edge of door- plate 4a and 4b is close to each other, and as Figure 1A and shown in Figure 2, the positioning plate 50a of one of them door-plate 4a extends to the assembling side of another door-plate 4b, the positioning plate 50b of another door-plate 4b extends to the assembling side of this door-plate 4a simultaneously, as shown in Figure 4.Thereby during being in open mode, door- plate 4a and 4b are separated from one another, and shown in the arrow of Fig. 4, one of them positioning plate 50a and another positioning plate 50b move close each other.
Then, after a mobile preset distance and one of them positioning plate 50a and another positioning plate 50b passed each other, one of them positioning plate 50a and another positioning plate 50b were separated from one another.
In off position down, locating dowel pin 37 is outstanding downwards dearly boundary plank 36 times usually, and injects between the positioning plate 50b of the positioning plate 50a of one of them door-plate 4a and another door-plate 4b.At this moment, the distance L 2 between the lateral edges of distance L 1 between the lateral edges of locating dowel pin 37 and one of them positioning plate 50a and locating dowel pin 37 and another one positioning plate 50b is respectively, for example 50 millimeters.
The explained later operation.
When elevator moved routinely, shown in Figure 1A, the passage 2 of passenger cabin 1 was closed by door-plate 4a and 4b.Do not give electromagnetic actuators 32 power supplies of limiting device 30.In off position down, shown in Fig. 2-5, locating dowel pin 37 and is inserted between the positioning plate 50b of the positioning plate 50a of one of them door-plate 4a and another door-plate 4b because it self the gravity and the propelling thrust of spring 41 promote downwards.Simultaneously, position probing bar 44 is detected by optical pickocff 48b, thereby identifies the position of locating dowel pin 37.
When passenger cabin 1 arrives a predetermined anchor point, give electromagnetic actuators 32 power supplies.In case give electromagnetic actuators 32 power supplies, plunger 38 is upwards drawn by means of electromagnetic force.Then, locating dowel pin 37 and plunger 38 make progress together, thereby leave the position between positioning plate 50a and the positioning plate 50b, arrive disarm state.Simultaneously, when detecting position probing bar 44 by optical pickocff 48a, the position of locating dowel pin 37 is identified.
When passenger cabin 1 rested in a destination floor, shown in Figure 1B, door- plate 4a and 4b were driven to the left and right by door driving arrangement 5 and slide, and the passage 2 of passenger cabin 1 is opened.Behind passenger cabin 1 about the passenger, door- plate 4a and 4b are driven closing passage 2 by door driving arrangement 5.The power supply of sever supply electromagnetic actuators 32 after door- plate 4a and 4b are closed.Then, locating dowel pin 37 and is inserted into the positioning plate 50a of door- plate 4a and 4b and the position between the 50b because the propelling thrust and the plunger 38 of self gravitation and spring 41 descend together.Then, door- plate 4a and 4b keep closed condition, passenger cabin 1 service of restarting under this state.
On the other hand, because power failure etc. are former thereby when cutting off, the passenger cabin 1 that is moving promptly stops, the power supply line that is used for a driving arrangement 5 automatically switches to the secondary battery 16 as emergency source of electrical power when the power supply 15 that is used to drive elevator.
When door- plate 4a and 4b are separated from each other about 40 millimeters the time in the direction of opening the door respectively, each suspension roller 12a, 13a, 12b and 13b arrive the 18a place, slope of sliding door upper rail 8 and 9.
At this moment, be necessary that applying a power F to each suspension roller 12a, 13a, 12b and 13b gets over slope 18a with opposing terrestrial attraction.Yet, little as the pre-determined power F of driving force ratio of the door driving arrangement 5 of power supply starting by secondary battery 16.Therefore, when each suspension roller 12a, 13a, 12b and 13b arrived slope 18a, door- plate 4a and 4b slided about 40 millimeters in the direction of opening the door respectively, stop then, and the distance between them is remained on about 80 millimeters.
At passenger cabin 1 run duration, when being cut off owing to reason power supplys such as power failure have taken place, passenger cabin 1 is because this accident is stopped, and door- plate 4a and 4b move a preset distance (40 millimeters) respectively automatically, form a pre-fixed gap (80 millimeters) between door-plate 4a and 4b.Like this, air and the ambient air in the passenger cabin 1 fully circulates by the space.Thereby can ventilate suitably, in passenger cabin 1, anoxic can not take place.Therefore the passenger in the passenger cabin 1 can not feel sick.
In addition, owing to form the space of a preset width between door- plate 4a and 4b, the passenger in the passenger cabin 1 can recognize the situation of outside by the space.The alarmed sensation that the passenger is closed in the closed room will be alleviated.
On the other hand, when the passenger in the passenger cabin 1 attempts to put into the space and open door- plate 4a and 4b by handle, door- plate 4a and 4b mobile is restricted in the direction of opening the door about 10 millimeters, further slides thereby positioning plate 50a and 50b lean against on the locating dowel pin 37 restriction.Therefore, the space that is formed between door-plate 4a and the 4b is limited to less than 100 millimeters, and the space no longer enlarges.Passenger cabin 1 can make the passenger in it be unlikely to have the danger of falling down from the space, thereby guarantees safety.
In addition, when the propulsive effort of door driving arrangement 5 generations has surpassed power F, door- plate 4a and 4b further move in the direction of opening the door, make each suspension roller 12a, 13a, 12b and 13b under propulsive effort, get over slope 18a, and the positioning plate 50a of door- plate 4a and 4b and 50b lean against on the locating dowel pin 37, prevent further and move.Like this, door- plate 4a and 4b just can not open wideer.Therefore, the danger that the passenger in the passenger cabin 1 does not just fall down from the space, thus guarantee safety.
When passenger cabin 1 stops owing to accident, just in case door- plate 4a and 4b can not open owing to the fault of secondary battery 16, can use a voice notification device that drives by another secondary battery to produce an announcement and point out the passenger in the passenger cabin 1 to come manual unlocking door- plate 4a and 4b.
Second embodiment is shown in Fig. 6 A and 6B.In this embodiment, only connect a common power to door driving arrangement 5, emergency source of electrical power is free of attachment on it.
Winding apparatus 20a and 20b are set as driver train in the both sides of stay bearing plate 6.Each winding apparatus 20a and 20b comprise a spool 21, a spring 22 and line parts 23.Spool 21 rolls on stay bearing plate 6.Spring 22 is at rotating direction elastic drive spool 21.Line parts 23 are one one ends on the spool 21, and the other end is connected to the suspension 11a of door- plate 4a and 4b and the line on the 11b.
Door- plate 4a and 4b by the elastic force of spring 22 by line parts 23 in the direction separated from one another or the direction elastic drive of opening the door.Propulsive effort can slide into the position of groove 18 along the direction of opening the door with the door-plate 4a in off position and 4b, and this power little power of required power when being set to get over the slope 18a of sliding door upper rail 8 and 9 than each suspension roller 12a, 13a, 12b and 13b.
When predetermined electric signal of input, the door driving arrangement 5 that drives door- plate 4a and 4b moves door-plate 4a and the 4b that is under the closed condition, thereby utilize electric power to make its passage of opening separated from one another, perhaps move door-plate 4a and the 4b that is in open mode, thus the propulsive effort that makes it overcome winding apparatus 20a and 20b closing passage close to each other.When power supply was given 5 power supplies of door driving arrangement, under door- plate 4a and 4b were limited to move to remain on that state in off position, when the power supply of powering for door driving arrangement 5 is cut off, and door-plate 4a and the 4b state that lifts restrictions.
Passenger cabin door equipment 3 in this embodiment also is provided with and the similar limiting device 30 of limiting device shown in Fig. 2-5.Therefore with reference to figure 2-5 interpreter operation.
In the normal service of elevator, as shown in Figure 6A, the passage 2 of passenger cabin 1 is closed by door-plate 4a and 4b.Do not give electromagnetic actuators 32 power supplies of limiting device 30.Shown in Fig. 3-5, in off position down, locating dowel pin 37 descends owing to the propelling thrust of self gravitation and spring 41, and is inserted into the position between the positioning plate 50b of the positioning plate 50a of one of them door-plate 4a and another door-plate 4b.At this moment, when detecting position probing bar 44 by optical pickocff 48b, the position of locating dowel pin 37 is identified.
When the passenger cabin 1 that is moving enters predetermined anchor point, give electromagnetic actuators 32 power supplies.By giving electromagnetic actuators 32 power supplies, plunger 38 is upwards attracted owing to electromagnetic force.Then, locating dowel pin 37 and plunger 38 upwards draw together, leave the position between positioning plate 50a and the positioning plate 50b.As a result, limiting device 30 becomes disarm state.At this moment, when detecting position probing bar 44 by optical pickocff 48a, the position of locating dowel pin 37 is identified.
When passenger cabin 1 rested in a predetermined floor, door- plate 4a and 4b were driven traction to the left and right by door driving arrangement 5, and shown in Fig. 6 B, the passage 2 of passenger cabin 1 is opened.Behind passenger cabin 1 about the passenger, door- plate 4a and 4b are driven by door driving arrangement 5 once more, thus closing passage 2.After shutoff operation, stop to electromagnetic actuators 32 power supplies.Locating dowel pin 37 and is inserted into the positioning plate 50a of door- plate 4a and 4b and the position between the 50b because the gravity of self and the propelling thrust and the plunger 38 of spring 41 descend together.Correspondingly, passenger cabin 1 remains under the closure state of door- plate 4a and 4b, the service of restarting under this state.
When door- plate 4a and 4b when the direction of opening the door moves, the line parts 23 of winding apparatus 20a and 20b wind the line to spool 21 by means of the propulsive effort of spring 22, when door- plate 4a and 4b when closing direction moves, the propulsive effort that line parts 23 overcome spring 22 unwrapping wire from the spool 21.
On the other hand, because the power failure power supply is cut off, passenger cabin 1 is promptly out of service, and the door-plate 4a and the 4b that are kept by door driving arrangement 5 just are released.
Door- plate 4a and 4b by winding apparatus 20a and 20b elastic drive on direction separated from one another, being pulled, thereby open passage.When the restriction of door driving arrangement 5 was disengaged, door- plate 4a and 4b moved in the direction of opening the door by means of the propulsive effort of corresponding winding apparatus 20a and 20b, thereby a space occurs between door- plate 4a and 4b.
When door- plate 4a and 4b are pulled and about 40 millimeters separated from one another the time, each suspension roller 12a, 13a, 12b and 13b arrive the 18a place, slope of sliding door upper rail 8 and 9 in the direction of opening the door respectively.
At this moment, be necessary that applying a power F to each suspension roller 12a, 13a, 12b and 13b makes it overcome terrestrial attraction to get over slope 18a.Yet it is little that the elastic drive power that winding apparatus 20a and 20b provide is set to specific force F in advance.Therefore, door- plate 4a and 4b approximately move 40 millimeters in the direction of opening the door respectively, and stop owing to each suspension roller 12a, 13a, 12b and 13b arrive slope 18a, at this moment, produce an about space of 80 millimeters between door- plate 4a and 4b.
When owing to power failure taking place under the running state of passenger cabin 1 stop power supply, passenger cabin 1 is because this emergency situation stops, and door- plate 4a and 4b open one 40 millimeters preset distance respectively automatically, thereby forms one 80 millimeters space between them.Like this, air and the extraneous air in the passenger cabin 1 fully circulates by the space.Therefore, the ventilation in the passenger cabin 1 is carried out suitably, anoxic can not take place in passenger cabin 1.Passenger in the passenger cabin 1 does not feel bad with regard to not feeling like this.
In addition, owing to the space of a preset width occurs between door- plate 4a and 4b, the passenger in the passenger cabin 1 can search the situation of outside by the space.Therefore, the alarmed sensation that is confined in the sealing chamber of passenger will be eliminated.
On the other hand, when the passenger in the passenger cabin 1 attempts to put into the space and open door- plate 4a and 4b by handle, door- plate 4a and 4b mobile is limited in the direction of opening the door about 10 millimeters, because positioning plate 50a and 50b lean against on the locating dowel pin 37, limited further slip.Therefore, the space that is formed between door-plate 4a and the 4b is limited in 100 millimeters, and door- plate 4a and 4b no longer open wideer.Passenger in the passenger cabin 1 is safe, the danger of not falling down from the space.
Horizontal sliding door plate 4a on the direction of opening the door that is provided by winding apparatus 20a and 20b and the power of 4b are changed into according to the angle of line parts 23 and are departed from horizon.That is to say that when line parts 23 depart from horizontal angle when very little, the horizontal decomposing force of mobile door- plate 4a and 4b is big, when line parts 23 depart from horizontal angle when very steep, the horizontal decomposing force of mobile door- plate 4a and 4b just diminishes.
When door- plate 4a and 4b are in closed condition following time, it is very little that the line parts 23 of winding apparatus 20a and 20b depart from horizontal angle, when door- plate 4a and 4b when the direction of opening the door moves, this angle is steepening gradually.
