Detailed description of the invention
Below embodiments of the present invention are described.
Fig. 1 is the integral structure figure of the double-deck elevator involved by present embodiment, and the double-deck elevator of present embodiment has the floor level auto modification mechanism 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, floor level auto modification mechanism control panel 6, floor level auto modification mechanism 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.Car external frame control panel 2 and up direction emergency braking apparatus control panel 16 are arranged in Machine Room, and floor level auto modification mechanism control panel 6 is arranged in car external frame 1.Be arranged in car external frame 1 as the upper car 4 of lift car and lower car 5.
Car external frame 1 and counterbalanced weight 13 are connected to the two ends of same hoist cable.The weight of counterbalanced weight 13 is when carrying the predetermined weight suitable with the total body weight of the passenger of regulation number in upper car 4 and lower car 5 and car external frame 1 keeps the weight that balances.Drive this hoist cable by car external frame winch 3, car external frame 1 upwards or is downwards travelled.Car external frame to car external frame winch 3 sending action command signal, makes car external frame 1 drive to the position of regulation with control panel 2.
When car external frame 1 there occurs exception and makes car external frame 1 upwards to travel with the speed of exception or driven to out-of-the way position at up direction in the process upwards travelled, car external frame control panel 2 makes car external frame 1 slow down or stop.When car external frame 1 cannot be slowed down in time or deceleration or hold function cannot normally work, car external frame 1 upwards drives to out-of-the way position, and meanwhile, counterbalanced weight 13 drops to out-of-the way position.Now, counterbalanced weight 13 and energy disperser 14 collide, and energy disperser 14, while mitigation impulsive force, bears counterbalanced weight 13.Now, car external frame 1 carries out emergency braking (emergent stopping).
Upper car 4 and lower car 5 are suspended in car external frame 1 by floor level correction hoist cable 8, when driving floor level correction hoist cable 8 by floor level auto modification mechanism with winch 7, the interval between upper car 4 and lower car 5 changes.Floor level auto modification mechanism with control panel 6 with the concerted action of car external frame control panel 2 to floor level auto modification mechanism winch 7 sending action command signal, interval between upper car 4 and lower car 5 is adjusted, make 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 stopped floor respectively.
The guide rail 17,18 extended along the vertical direction is fixed in car external frame 1.This guide rail 17,18 is for being fixed on car external frame 1 by upper car 4 and lower car 5 when emergent stopping.Guide rail 17,18 can be arranged to the special guide rail of emergent stopping, also can be arranged to have concurrently the function only limiting upper car 4 and lower car 5 movement in car external frame 1 in the vertical direction.
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 ~ 12 is the relative movement suppression parts suppressed relative to the rising of car external frame 1 to upper car 4 and lower car 5.
Up direction emergency braking apparatus 9 is arranged near guide rail 17, and it contacts with guide rail 17 according to the action command signal from up direction emergency braking apparatus control panel 16, suppresses the movement relative to car external frame 1 of upper car 4.Specifically, up direction emergency braking apparatus 9 carries out emergency braking action, clamps guide rail 17 by the not shown clamping device as stop mechanism, produces the restraint suppressing upper car 4 relative to car external frame 1 movement thus.
Up direction emergency braking apparatus 10 is arranged near guide rail 18, and it contacts with guide rail 18 according to the action command signal from up direction emergency braking apparatus control panel 16, suppresses the movement relative to car external frame 1 of upper car 4.Specifically, up direction emergency braking apparatus 10 is clamped guide rail 18 by not shown clamping device and is produced the restraint suppressing upper car 4 relative to car external frame 1 movement.
Equally, up direction emergency braking apparatus 11 is arranged near guide rail 17, and it contacts with guide rail 17 according to the action command signal from up direction emergency braking apparatus control panel 16, suppresses the movement relative to car external frame 1 of lower car 5.Specifically, up direction emergency braking apparatus 11 is clamped guide rail 17 by not shown clamping device and is produced the restraint suppressing lower car 5 relative to car external frame 1 movement.
Up direction emergency braking apparatus 12 is arranged near guide rail 18, and it contacts with guide rail 18 according to the action command signal from up direction emergency braking apparatus control panel 16, suppresses the movement relative to car external frame 1 of lower car 5.Specifically, up direction emergency braking apparatus 12 is clamped guide rail 18 by not shown clamping device and is produced the restraint suppressing lower car 5 relative to car external frame 1 movement.
Up direction emergency braking apparatus 9 ~ 12 is such as can clamp guide rail 17,18 with powerful power, with the device be fixed upper car 4 or lower car 5 in moment.
Up direction emergency braking apparatus 9 ~ 12 is made to carry out emergency braking action and clamp guide rail 17,18 with powerful power, suppress upper car 4 and lower car 5 up play thus, therefore, guide rail 17,18 may be caused to wear away when carrying out emergency braking action or damage.Therefore, preferably guide rail 17,18 is arranged to be arranged on removably in car external frame 1, makes it possible to change guide rail 17,18.
When car external frame 1 carries out emergency braking (emergent stopping) in up process, up direction emergency braking apparatus to up direction emergency braking apparatus 9 ~ 12 sending action command signal, carries out emergent stopping action to make it with control panel 16.
Up direction emergency braking apparatus control panel 16 is control parts of up direction emergency braking apparatus 9 ~ 12.As an example, when inferring that car external frame 1 can rise to the out-of-the way position of regulation, up direction emergency braking apparatus to up direction emergency braking apparatus 9 ~ 12 sending action command signal, makes it before car external frame 1 rises to the out-of-the way position of regulation, carry out emergent stopping action 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 collide.Collided 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 in car external frame 1 up play.Emergent stopping action is used for preventing upper car 4 and lower car 5 from above-mentioned up play occurring.
In addition, the double-deck elevator of present embodiment has position detecting function and velocity measuring function.Position detecting function is the function of the position detecting car external frame 1, and velocity measuring function is the function of the moving velocity detecting car external frame 1.Such as also can be arranged to car external frame winch 3 and have the rotary encoder exporting pulsatile once signal every certain rotation amount, up direction emergency braking apparatus control panel 16 comes detection position and moving velocity according to the impulse singla of this rotary encoder.Now, in fact car external frame winch 3 and up direction emergency braking apparatus control panel 16 play the function of car external frame position detection part and the function of car external frame velocity measuring part.
Whether up direction emergency braking apparatus control panel 16 can rise to out-of-the way position according to the moving velocity of car external frame 1 and position prediction car external frame 1 further.
Whether end floor car position detector switch 15 detects car external frame 1 and has risen in the side, front (downside) of the out-of-the way position that emergent stopping occurs and the process starting position of this out-of-the way position at a distance of predetermined distance.Specifically, end floor car position detector switch 15 is arranged on process starting position, and connects (ON) when car external frame 1 arrives the position at himself place.
This process starting position is the position that up direction emergency braking apparatus control panel 16 starts to process, this process starting position is the position that upper car 4 and lower car 5 can be suppressed before car external frame 1 arrives out-of-the way position to rise relative to car external frame 1, namely can clamp the position of guide rail 17,18 with up direction emergency braking apparatus 9 ~ 12.Certain distance is needed between above-mentioned process starting position and out-of-the way position, even if make when car external frame 1 rises with maximum speed, also can guarantee before counterbalanced weight 13 collides with energy disperser 14, judged whether to carry out emergent stopping action by up direction emergency braking apparatus control panel 16, and when being judged as carrying out emergent stopping action, send the action command signal that indicating emergency stops action, with this by up direction emergency braking apparatus 9 ~ 12 actual time of clamping required for guide rail 17,18.
When end floor car position detector switch 15 detects that car external frame 1 has risen to process starting position, up direction emergency braking apparatus control panel 16 starts the process carrying out suppressing upper car 4 and lower car 5 to rise relative to car external frame 1.
The a series of action of the double-deck elevator of present embodiment is as follows: in the process that car external frame 1 travels upward, when end floor car position detector switch 15 has carried out action (connection), whether up direction emergency braking apparatus control panel 16 has made up direction emergency braking apparatus 9 ~ 12 action according to the moving velocity of car external frame 1 and position judgment.When being judged as making 9 ~ 12 action of up direction emergency braking apparatus, up direction emergency braking apparatus control panel 16 makes up direction emergency braking apparatus 9 ~ 12 clamp the guide rail 17,18 being arranged on car external frame 1 two ends before emergent stopping occurs, and prevents upper car 4 and the lower car 5 up play when emergency braking with this.
Below the action of the double-deck elevator of present embodiment is described in detail.
In the present embodiment, suppose that car external frame 1 cannot normal control rate in the process travelled upward, although initial safety device has carried out action, but do not have to make car external frame 1 stop, thus under this worst condition, counterbalanced weight 13 and energy disperser 14 there occurs collision.Further, suppose now to be provided with for preventing upper car 4 and lower car 5 because of up play and the up direction emergency braking apparatus 9 ~ 12 collided with car external frame 1.That is, this function is the safety device of in the end stage action.
The end floor car position detector switch 15 of Fig. 1 is the binary pair that calculation process is started, the calculation process being used in up direction emergency braking apparatus 9 ~ 12 action starts, the setting position of this end floor car position detector switch 15 is considering up direction emergency braking apparatus control panel 16 to up direction emergency braking apparatus 9 ~ 12 sending action command signal to make the time (cranking time of up direction emergency braking apparatus 9 ~ 12) needed for up direction emergency braking apparatus 9 ~ 12 action, suppose to infer under safety device has carried out this state of action the maximum speed of the car external frame 1 and car external frame 1 to become free-falling body because of uncontrollable speed time acceleration/accel (acceleration of free fall) basis on determine.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
Counterbalanced weight 13 when L arrives the setting position of end floor car position detector switch 15 with car external frame 1 and the distance between energy disperser 14 represent.A, V, T are all by the structure of double-deck elevator and the constant arranging the decisions such as state.
Fig. 2 is the diagram of circuit of the action of the double-deck elevator representing present embodiment.Process shown in Fig. 2 performs primarily of up direction emergency braking apparatus control panel 16.
First, up direction emergency braking apparatus control panel 16 judges whether end floor car position detector switch 15 has carried out action, namely judges whether car external frame 1 has risen to the position (step ST01) at floor car position detector switch 15 place, end.If be judged as that car external frame 1 does not also rise to the position at floor car position detector switch 15 place, end, up direction emergency braking apparatus control panel 16 directly ends process.In the present embodiment, be that counterbalanced weight 13 and energy disperser 14 collide and cause this situation of car external frame 1 emergent stopping due to what need reply, so except car external frame 1 is close to except the occasion near the superiors, this function is failure to actuate.
Then, up direction emergency braking apparatus control panel 16 carries out Distance Remaining calculation process (step ST02) according to the impulse singla from rotary encoder.So-called Distance Remaining calculation process refers to the process of the spacing (Distance Remaining) of computing counterbalanced weight 13 and energy disperser 14.
After this, up direction emergency braking apparatus determines the speed (step ST03) of up direction emergency braking action with the velocity mode of the up direction emergency braking action of control panel 16 according to Distance Remaining and Fig. 3.Fig. 3 is the diagram of curves of the velocity mode of the emergency braking action of up direction.The velocity mode of the emergency braking action of up direction be according to the relation between Distance Remaining and the moving velocity of car external frame 1 represent counterbalanced weight 13 with or the marginal curve that do not collide with energy disperser 14.The Distance Remaining part calculated shown in Fig. 3, the speed that the Curves of the velocity mode of the emergency braking action of up direction represents is exactly the speed of up direction emergency braking action.
Also show the curve of normal speed mode in figure 3.The pattern of velocity variations when normal speed mode represents elevator regular calling end floor (the superiors) of present embodiment.Even if when car external frame 1 exceeds the setting position of end floor car position detector switch 15 and rises with the moving velocity faster than normal speed mode, as long as moving velocity is slower than the velocity mode of the emergency braking action of up direction, the situation that counterbalanced weight 13 collides with energy disperser 14 would not be there is.
In addition, up direction emergency braking apparatus control panel 16 detects the actual moving velocity (step ST04) of car external frame 1 further, and the speed of this actual moving velocity and up direction emergency braking action is compared (step ST05).
Relative to the value of the Distance Remaining calculated, reality moving velocity than the emergency braking action of up direction velocity mode represented by the speed of up direction emergency braking action faster time, be speculated as counterbalanced weight 13 to collide with energy disperser 14, so be necessary to carry out emergent stopping action, to clamp guide rail 17,18 by up direction emergency braking apparatus 9 ~ 12.On the other hand, relative to the value of the Distance Remaining calculated, reality moving velocity than the emergency braking action of up direction velocity mode represented by the speed of up direction emergency braking action slow time, be speculated as counterbalanced weight 13 to collide with energy disperser 14, so there is no need the emergent stopping action of carrying out being clamped guide rail 17,18 by up direction emergency braking apparatus 9 ~ 12.
If when being judged as that in step ST05 actual moving velocity is faster than the speed of up direction emergency braking action, up direction emergency braking apparatus control panel 16 sends the action command signal (step ST06) clamping guide rail 17,18 to up direction emergency braking apparatus 9 ~ 12.On the other hand, if when being judged as that in step ST05 actual moving velocity is slower than the speed of up direction emergency braking action, up direction emergency braking apparatus control panel 16 directly ends process.
As mentioned above, double-deck elevator according to the present embodiment, when counterbalanced weight 13 and energy disperser 14 collide and cause the car external frame 1 of up direction to carry out emergent stopping, guide rail 17,18 is clamped by up direction emergency braking apparatus 9 ~ 12, upper car 4 and lower car 5 up play upper car 4 and lower car 5 can be fixed in car external frame 1, so can be prevented when there occurs collision.
In addition, double-deck elevator according to the present embodiment, owing to predicting whether the car external frame 1 of up direction can collide and emergent stopping because of counterbalanced weight 13 and energy disperser 14, and only make up direction emergency braking apparatus 9 ~ 12 action when being predicted as and can colliding, so upper car 4 and lower car 5 up play can be prevented when there occurs collision, and when colliding, up direction emergency braking apparatus 9 ~ 12 action unnecessarily can not be made.
In the present embodiment, up direction emergency braking apparatus 9 ~ 12 just clamps guide rail 17,18 when car external frame 1 carries out emergent stopping, but the present invention is not limited to this.
Up direction emergency braking apparatus 9 ~ 12 also can be arranged to be had whether clamping the function of guide rail 17,18 in the function detected that normally works.Preferably being arranged to can occasion beyond emergent stopping, such as by supervisory personnel by operating switch etc., clamp the action of guide rail 17,18 manually to make up direction emergency braking apparatus 9 ~ 12 carry out.
Further, up direction emergency braking apparatus 9 ~ 12 also can be arranged in not change between upper car 4 and lower car 5 and clamp guide rail 17,18 during interval all the time.Such as, also the interval that can be arranged between upper car 4 and lower car 5 does not change, and car external frame 1 is during up direction travels, and makes up direction emergency braking apparatus 9 ~ 12 clamp guide rail 17,18 in advance.By making up direction emergency braking apparatus 9 ~ 12 action continually, can confirm that whether up direction emergency braking apparatus 9 ~ 12 is normal.In addition, the action of the upper car 4 between the rising stage and lower car 5 can be made to become more stable.
In addition, between the rising stage that yet can be arranged in car external frame 1, do not make the interval between upper car 4 and lower car 5 change, and make up direction emergency braking apparatus 9 ~ 12 clamp guide rail 17,18 in the meantime all the time.By setting like this, can detect emergent stopping or predict, thus not need the emergency control carrying out making up direction emergency braking apparatus 9 ~ 12 action.
The embodiment of the invention described above is not limited in above-mentioned embodiment for the example that the present invention will be described, the present invention.Industry personnel can adopt other various modes to implement the present invention without departing from the scope of spirit of the present invention.
