The specific embodiment
Below embodiments of the present invention are described.
Fig. 1 is the integral structure figure of the related double-deck elevator of present embodiment, and the double-deck elevator of present embodiment has the automatic correction mechanism of floor level of hoist cable mode.
The double-deck elevator of present embodiment has car external frame 1, car external frame control panel 2, car external frame winch 3, upper car 4, lower car 5, the automatic correction mechanism of floor level control panel 6, the automatic correction mechanism of floor level winch 7, floor level correction hoist cable 8, up direction emergency braking apparatus 9～12, counterbalanced weight 13, energy disperser 14, end floor car position detector switch 15, up direction emergency braking apparatus control panel 16 and guide rail 17,18.The car external frame is arranged in the Machine Room with control panel 16 with control panel 2 and up direction emergency braking apparatus, and the automatic correction mechanism of floor level is arranged on the car external frame 1 with control panel 6.Upper car 4 and lower car 5 as lift car are installed in the car external frame 1.
Car external frame 1 and counterbalanced weight 13 are connected to the two ends of same hoist cable.The weight of counterbalanced weight 13 when in upper car 4 and lower car 5, carrying the suitable predetermined weight of total body weight with the passenger of regulation number with the weight of car external frame 1 maintenance balance.Drive this hoist cable by the car external frame with winch 3, make car external frame 1 make progress or travel downwards.The car external frame to car external frame winch 3 sending action command signals, makes car external frame 1 drive to the position of regulation with control panel 2.
When car external frame 1 has occured unusual in the process of upwards travelling and so that car external frame 1 is upwards travelled with unusual speed or when up direction had driven to out-of-the way position, the car external frame made 1 deceleration of car external frame with control panel 2 or stops.When in time deceleration of car external frame 1 or deceleration or hold function can't work, car external frame 1 upwards drove to out-of-the way position, and meanwhile, counterbalanced weight 13 drops to out-of-the way position.At this moment, counterbalanced weight 13 and energy disperser 14 collisions, energy disperser 14 bears counterbalanced weight 13 when relaxing impulsive force.At this moment, car external frame 1 is carried out emergency braking (emergent stopping).
Upper car 4 and lower car 5 are suspended in the car external frame 1 with hoist cable 8 by the floor level correction, when driving the floor level correction with hoist cable 8 by the automatic correction mechanism of floor level with winch 7, the interval between upper car 4 and the lower car 5 changes.The automatic correction mechanism of floor level uses control panel 2 concerted actions to the automatic correction mechanism of floor level winch 7 sending action command signals with control panel 6 and car external frame, interval between upper car 4 and the lower car 5 is adjusted, so that on the stop position of car external frame 1, the floor level of upper car 4 and lower car 5 is consistent with the floor level of the floor of stopping respectively.
The guide rail 17,18 that extends along the vertical direction is fixed in the car external frame 1.This guide rail 17,18 is used for when emergent stopping upper car 4 and lower car 5 being fixed on car external frame 1.Guide rail 17,18 can be arranged to the guide rail of emergent stopping special use, only also can be arranged to have concurrently in above-below direction restriction upper car 4 and lower car 5 function in the 1 interior movement of car external frame.
Upper car 4 is provided with up direction emergency braking apparatus 9,10, and lower car 5 is provided with up direction emergency braking apparatus 11,12.Up direction emergency braking apparatus 9～12nd, the inhibition part that relatively moves that the rising with respect to car external frame 1 of upper car 4 and lower car 5 is suppressed.
Up direction emergency braking apparatus 9 is arranged near the guide rail 17, and it suppresses the movement with respect to car external frame 1 of upper car 4 according to contacting with guide rail 17 from the action command signal of up direction emergency braking apparatus with control panel 16.Be specifically, up direction emergency braking apparatus 9 carries out the emergency braking action, clamps guide rail 17 by the not shown clamping device as stop mechanism, produces thus and suppresses the restraint that upper car 4 moves with respect to car external frame 1.
Up direction emergency braking apparatus 10 is arranged near the guide rail 18, and it suppresses the movement with respect to car external frame 1 of upper car 4 according to contacting with guide rail 18 from the action command signal of up direction emergency braking apparatus with control panel 16.That up direction emergency braking apparatus 10 is clamped guide rail 18 by not shown clamping device and produced the restraint that inhibition upper car 4 moves with respect to car external frame 1 specifically.
Equally, up direction emergency braking apparatus 11 is arranged near the guide rail 17, and it suppresses the movement with respect to car external frame 1 of lower car 5 according to contacting with guide rail 17 from the action command signal of up direction emergency braking apparatus with control panel 16.That up direction emergency braking apparatus 11 is clamped guide rail 17 by not shown clamping device and produced the restraint that inhibition lower car 5 moves with respect to car external frame 1 specifically.
Up direction emergency braking apparatus 12 is arranged near the guide rail 18, and it suppresses the movement with respect to car external frame 1 of lower car 5 according to contacting with guide rail 18 from the action command signal of up direction emergency braking apparatus with control panel 16.That up direction emergency braking apparatus 12 is clamped guide rail 18 by not shown clamping device and produced the restraint that inhibition lower car 5 moves with respect to car external frame 1 specifically.
Up direction emergency braking apparatus 9～12 for example is to clamp guide rail 17,18 with powerful power in moment, with the device that upper car 4 or lower car 5 are fixed.
Make up direction emergency braking apparatus 9～12 carry out emergency braking action and clamp guide rail 17,18 with powerful power, suppress thus up play of upper car 4 and lower car 5, therefore, when carrying out the emergency braking action, may cause guide rail 17,18 abrasion or damage.Therefore, preferably guide rail 17,18 is arranged to be installed in removably on the car external frame 1, makes it possible to guide rail 17,18 is changed.
When car external frame 1 was carried out emergency braking (emergent stopping) in up process, the up direction emergency braking apparatus, moved so that it carries out emergent stopping to up direction emergency braking apparatus 9～12 sending action command signals with control panel 16.
The up direction emergency braking apparatus is control parts of up direction emergency braking apparatus 9～12 usefulness with control panel 16.As an example, inferring in the situation of out-of-the way position that car external frame 1 can rise to regulation, the up direction emergency braking apparatus, makes and carries out the emergent stopping action before its out-of-the way position that rises to regulation in car external frame 1 to up direction emergency braking apparatus 9～12 sending action command signals with control panel 16.The position at car external frame 1 place when this out-of-the way position refers to that counterbalanced weight 13 and energy disperser 14 bump.Bump by counterbalanced weight 13 and energy disperser 14, car external frame 1 emergent stopping, in this case, upper car 4 and lower car 5 can be in car external frame 1 play up.The emergent stopping action is used for preventing that upper car 4 and lower car 5 from above-mentioned up play occuring.
In addition, the double-deck elevator of present embodiment has position detecting function and speed measuring ability.Position detecting function is the function that detects the position of car external frame 1, and the speed measuring ability is the function that detects the moving velocity of car external frame 1.For example also can be arranged to the car external frame and have rotary encoder every certain rotation amount output pulsatile once signal with winch 3, the up direction emergency braking apparatus comes detection position and moving velocity with control panel 16 according to the impulse singla of this rotary encoder.At this moment, in fact the car external frame brings into play the function of car external frame position detection part and the function of car external frame speed test section with winch 3 and up direction emergency braking apparatus with control panel 16.
Whether the up direction emergency braking apparatus further can rise to out-of-the way position according to moving velocity and the position prediction car external frame 1 of car external frame 1 with control panel 16.
Whether floor car position detector switch 15 detection car external frame 1 in end have risen to the front side (downside) and the processing starting position of this out-of-the way position at a distance of predetermined distance at the out-of-the way position that emergent stopping occurs.Be specifically, end floor car position detector switch 15 is arranged on to be processed on the starting position, and connects (ON) when car external frame 1 arrives the position at himself place.
This processing starting position is the position that the up direction emergency braking apparatus begins to process with control panel 16, this processing starting position is to suppress the position that upper car 4 and lower car 5 rise with respect to car external frame 1 before car external frame 1 arrives out-of-the way position, namely can clamp guide rail 17,18 position with up direction emergency braking apparatus 9～12.Need to have certain distance between above-mentioned processing starting position and the out-of-the way position, even so that in car external frame 1 during with the speed rising of maximum, also can guarantee before counterbalanced weight 13 and energy disperser 14 collide, judge whether to carry out the emergent stopping action by the up direction emergency braking apparatus with control panel 16, and carry out emergent stopping when action being judged as, send the action command signal that indicating emergency stops to move, with this by up direction emergency braking apparatus 9～12 actual clamping guide rail 17,18 needed times.
Detect car external frame 1 at end floor car position detector switch 15 and risen to when processing the starting position, the up direction emergency braking apparatus begins to suppress upper car 4 and lower car 5 with respect to the processing of car external frame 1 rising with control panel 16.
The a series of action of the double-deck elevator of present embodiment is as follows: car external frame 1 towards above in the process of travelling, in the situation that end floor car position detector switch 15 carried out moving (connection), whether the up direction emergency braking apparatus makes 9～12 actions of up direction emergency braking apparatus with control panel 16 according to moving velocity and the position judgment of car external frame 1.Be judged as when making up direction emergency braking apparatus 9～12 action, the up direction emergency braking apparatus so that up direction emergency braking apparatus 9～12 is clamped the guide rail 17,18 that is arranged on car external frame 1 two ends before emergent stopping occurs, prevents upper car 4 and lower car 5 when emergency braking up play with this with control panel 16.
Below the action of the double-deck elevator of present embodiment is described in detail.
In the present embodiment, suppose car external frame 1 towards above normal control rate in the process of travelling, although initial safety device moves, but there is not to make car external frame 1 to stop, thereby under this worst condition, collision has occured with energy disperser 14 in counterbalanced weight 13.And, suppose that be provided be used to the up direction emergency braking apparatus 9～12 that prevents that upper car 4 and lower car 5 from bumping because of play up and car external frame 1 this moment.That is to say, this function is the safety device of in the end stage action.
The end floor car position detector switch 15 of Fig. 1 is binary pairs that calculation process is begun, the calculation process that is used in 9～12 actions of up direction emergency braking apparatus begins, and the setting position of this end floor car position detector switch 15 is to consider that the up direction emergency braking apparatus is used control panel 16 to up direction emergency braking apparatus 9～12 sending action command signals so that the up direction emergency braking apparatus required time (cranking time of up direction emergency braking apparatus 9～12) of 9～12 actions, the basis of inferring the acceleration/accel (acceleration of free fall) the when maximum speed of the car external frame 1 that and car external frame 1 become free-falling body because of uncontrollable speed under the supposition safety device has carried out moving this state determines.The setting position of this end floor car position detector switch 15 determines according to following formula (1).
L=VT+1/2AT
2Formula (1)
L: the setting position of end floor car position detector switch 15
A: acceleration of free fall
V: the maximum speed of car external frame 1
T: the cranking time of up direction emergency braking apparatus 9～12
Fig. 2 is the diagram of circuit of action of the double-deck elevator of expression present embodiment.Processing shown in Figure 2 is mainly carried out with control panel 16 by the up direction emergency braking apparatus.
At first, the up direction emergency braking apparatus judges with control panel 16 whether end floor car position detector switch 15 moves, and judges namely whether car external frame 1 has risen to the position (step ST01) at floor car position detector switch 15 places, end.If be judged as the position that car external frame 1 does not also rise to floor car position detector switch 15 places, end, up direction emergency braking apparatus control panel 16 direct end process.In the present embodiment, be that counterbalanced weight 13 bumps with energy disperser 14 and causes this situation of car external frame 1 emergent stopping owing to what need reply, so except car external frame 1 near near the occasion the superiors, this function is failure to actuate.
Then, the up direction emergency braking apparatus carries out Distance Remaining calculation process (step ST02) with control panel 16 according to the impulse singla from rotary encoder.So-called Distance Remaining calculation process refers to the processing of distance (Distance Remaining) between computing counterbalanced weight 13 and the energy disperser 14.
After this, the up direction emergency braking apparatus determines the speed (step ST03) of up direction emergency braking action according to the velocity mode of Distance Remaining and up direction emergency braking shown in Figure 3 action with control panel 16.Fig. 3 is the diagram of curves of velocity mode of the emergency braking action of up direction.The velocity mode of the emergency braking of up direction action be according to the relation between the moving velocity of Distance Remaining and car external frame 1 represent counterbalanced weight 13 with or the marginal curve that do not collide with energy disperser 14.In the Distance Remaining part that calculates shown in Figure 3, the speed that the Curves of the velocity mode of the emergency braking of up direction action represents is exactly the speed of up direction emergency braking action.
In Fig. 3, also show the curve of normal speed mode.The pattern of the velocity variations when normal speed mode represents the elevator regular calling end floor (the superiors) of present embodiment.Even exceed in car external frame 1 under the setting position and the situation with the moving velocity rising faster than normal speed mode of end floor car position detector switch 15, as long as moving velocity is slower than the velocity mode of the emergency braking action of up direction, the situation of counterbalanced weight 13 and energy disperser 14 collisions just can not occur.
In addition, the up direction emergency braking apparatus further detects the actual moving velocitys (step ST04) of car external frame 1 with control panel 16, and should compare (step ST05) with the speed that the up direction emergency braking moves by actual moving velocity.
Value with respect to the Distance Remaining that calculates, when the speed of the moving velocity of the reality up direction emergency braking action more represented than the velocity mode of the emergency braking action of up direction is faster, being speculated as counterbalanced weight 13 will bump with energy disperser 14, so be necessary to carry out the emergent stopping action, to clamp guide rail 17,18 by up direction emergency braking apparatus 9～12.On the other hand, value with respect to the Distance Remaining that calculates, when the speed of the moving velocity of the reality up direction emergency braking action more represented than the velocity mode of the emergency braking action of up direction is slow, be speculated as counterbalanced weight 13 and can not bump with energy disperser 14, so there is no need to carry out to clamp guide rail 17,18 emergent stopping action by up direction emergency braking apparatus 9～12.
If be judged as actual moving velocity when faster than the speed of up direction emergency braking action in step ST05, the up direction emergency braking apparatus sends to up direction emergency braking apparatus 9～12 with control panel 16 and clamps guide rail 17,18 action command signal (step ST06).On the other hand, if be judged as actual moving velocity when slower than the speed of up direction emergency braking action in step ST05, the up direction emergency braking apparatus is with control panel 16 direct end process.
As mentioned above, double-deck elevator according to present embodiment, bump and when causing the car external frame 1 of up direction to carry out emergent stopping at counterbalanced weight 13 and energy disperser 14, clamp guide rail 17,18 by up direction emergency braking apparatus 9～12, upper car 4 and lower car 5 can be fixed on the car external frame 1, so can when collision has occured, prevent up play of upper car 4 and lower car 5.
In addition, double-deck elevator according to present embodiment, because whether the car external frame 1 of prediction up direction can be because of counterbalanced weight 13 and energy disperser 14 emergent stopping that bumps, and only make up direction emergency braking apparatus 9～12 action in the time of can bumping being predicted as, so can when collision has occured, prevent up play of upper car 4 and lower car 5, and in the time can not bumping, can not make 9～12 actions of up direction emergency braking apparatus meaninglessly.
In the present embodiment, 9～12 of up direction emergency braking apparatus are just clamped guide rail 17,18 when car external frame 1 is carried out emergent stopping, but the present invention is not limited to this.
Up direction emergency braking apparatus 9～12 also can be arranged to have the function that whether detects in normal operation clamping guide rail 17,18 function.Preferably being arranged to can be in the occasion beyond the emergent stopping, such as by the supervisory personnel by switch etc. is operated, clamp guide rail 17,18 action manually to make up direction emergency braking apparatus 9～12.
And, up direction emergency braking apparatus 9～12 also can be arranged in do not change interval between upper car 4 and the lower car 5 during clamp all the time guide rail 17,18.For example, the interval that yet can be arranged between upper car 4 and the lower car 5 does not change, and car external frame 1 up direction travel during, make up direction emergency braking apparatus 9～12 clamp in advance guide rail 17,18.By up direction emergency braking apparatus 9～12 is moved continually, can confirm whether up direction emergency braking apparatus 9～12 is normal.In addition, can make upper car 4 between the rising stage and the action of lower car 5 become more stable.
In addition, also can be arranged between the rising stage of car external frame 1, the interval between upper car 4 and the lower car 5 is changed, and make all the time in the meantime up direction emergency braking apparatus 9～12 clamp guide rail 17,18.By setting like this, can detect or predict emergent stopping, thereby not need to make the emergency control of up direction emergency braking apparatus 9～12 actions.
The embodiment of the invention described above is to be not limited in above-mentioned embodiment for the example that the present invention will be described, the present invention.Industry personnel can adopt other variety of way to implement the present invention in the scope that does not break away from aim of the present invention.
