Efferent 36 determines whether the critical activity from power receiving section 32 is offered each emergency braking device 10 with power supply according to from the 1st and the 2nd detection unit 38,40 information separately when urgent.That is, efferent 36 determines whether the critical activity from power receiving section 32 is offered each emergency braking device 10 with power supply according to the judgement of the 1st detection unit 38 and this dual judgement of judgement of the 2nd detection unit 40 when urgent.
Stand-by circuit 31 is according to judging from the electric power size of the 1st and the 2nd electrical generator 26,27 whether the speed of car 3 has unusually, and only will offer electromagnetic drive part 12 from the electric power of the 1st and the 2nd electrical generator 26,27 when being unusual when the speed that is judged to be car 3.Be set with the abnormality juding setting value in stand-by circuit 31, whether this abnormality juding has unusual benchmark as being used for by comparing the speed of judging car 3 with electric power size from the 1st and the 2nd electrical generator 26,27 with setting value.The abnormality juding setting value is the value greater than rated speed of lift.
Each emergency braking device 10 provides electric power to work by a certain at least direction electromagnetic drive part 12 from speed regulation device 30 and stand-by circuit 31, and its generation of forced is for the braking force of car 3.
The following describes work. car 3 is in hoistway 1 when mobile, the the 1st and the 2nd follow- up pulley 14,15 rotates according to the speed of car 3. thus, be provided to speed regulation device 30 and stand-by circuit 31 with the cooresponding electric power of the speed of car 3 from the 1st and the 2nd electrical generator 26,27, from the speed cooresponding signal of the 1st and the 2nd car speed detector 28,29 to speed regulation device 30 transmission and car 3.
The Control work of speed regulation device 30 is by carrying out from the electric power supply of the 1st and the 2nd electrical generator 26,27.By the Control work of speed regulation device 30, whether the speed of carrying out car 3 based on the signal from the 1st car speed detector 28 in the 1st handling part 34 has unusual judgement; Whether the speed of carrying out car 3 based on the signal from the 2nd car speed detector 29 in the 2nd handling part 35 has unusual judgement.
And, in stand-by circuit 31, with the judgement of speed regulation device 30 concurrently, according to electric power size, judge whether the speed of car 3 has unusually from the 1st and the 2nd electrical generator 26,27.
When elevator operates as normally, the speed of car 3 is for just often, stops respectively the electric power supply of carrying out from speed regulation device 30 and 31 pairs of each emergency braking devices 10 of stand-by circuit.Thus, car 3 can be owing to the action of each emergency braking device 10 is forced to stop.
For example when because fracture of main rope 9 etc. and the velocity anomaly of car 3 increases, when the speed that at least one side by the 1st and the 2nd handling part 34,35 is judged to be car 3 was unusual, efferent 36 provided by the 1st, the 2nd electrical generator 26,27 electric power that produced to each emergency braking device 10 during from speed regulation device 30 urgent.

And since the 1st, the 2nd electrical generator 26,27 be installed on the car 3, so for example can prevent to carry out power supply more reliably for each emergency braking device 10 owing to power supply for each emergency braking device 10 is cut off in the fracture of control cable 25 etc.
And, the the 1st and the 2nd car speed detector 28,29 produces the cooresponding signal of speed with car 3, whether speed regulation device 30 bases have unusually from the speed of the signal determining car 3 of the 1st and the 2nd car speed detector 28,29, and and if only if when to be judged to be the speed of car 3 be unusual, to give each emergency braking device 10 from the electric power supply of the 1st, the 2nd electrical generator 26,27, so can prevent the misoperation of each emergency braking device 10, the work of each emergency braking device 10 the when speed that can also carry out car 3 more reliably is unusual.
And owing to the 1st and the 2nd car speed detector 28,29 is installed on the car 3, so can more reliably the signal from the 1st and the 2nd car speed detector 28,29 be transferred to speed regulation device 30.
In addition, pulley gear 17 has the 1st and the 2nd follow- up pulley 14,15 that rotates according to the speed of car 3, speed regulation device 30 judges according to the rotation of the 1st and the 2nd follow-up pulley 14,15 whether the speed of car 3 has unusually, so can carry out the judgement of speed regulation device 30 with simple structure more reliably.
In addition, have owing to speed regulation device 30: judge according to the rotation of the 1st follow-up pulley 14 whether the speed of car 3 has the 1st unusual handling part 34; Judge according to the rotation of the 2nd follow-up pulley 15 whether the speed of car 3 has the 2nd unusual handling part 35; And efferent 36 when urgent, efferent 36 was according to respectively from the information of the 1st and the 2nd handling part 34,35 when this was urgent, when the speed that is judged to be car 3 by a certain at least side in the 1st and the 2nd handling part 34,35 when being unusual, to give emergency braking device 10 from the electric power supply of the 1st and the 2nd electrical generator 26,27, so whether the speed about car 3 has unusually, can carry out a plurality of judgements, whether can improve reliability to the judgement of each emergency braking device 10 power supply.Thus, can further prevent the misoperation of emergency braking device 10.
And, on the 1st and the 2nd follow-up pulley 14,15, be wound with governor rope 18, the tensioning on above-below direction in hoistway 1 of this governor rope 18, and the 1st and the 2nd follow- up pulley 14,15 is trapped among together, the 1st with the 2nd follow-up pulley 14,15 by force application apparatus 16 each other from direction on the application of force, thereby governor rope 18 is applied tension force, so can between the 1st and the 2nd follow-up pulley 14,15 and governor rope 18, produce big friction force, can prevent that the 1st and the 2nd follow-up pulley 14,15 from producing slip with respect to governor rope 18.Thus, the 1st and the 2nd follow-up pulley 14,15 is rotated more reliably corresponding to the speed of car 3.
In addition, because governor rope 18 is connected with the top of hoistway 1 by spring 21, be connected by the bottom of spring 22 with hoistway 1, so can apply tension force to governor rope 18, even can also owing to through the time change to wait the length that makes governor rope 18 to extend situation under also can absorb the prolongation of governor rope 18 by the elasticity of spring 21,22, can prevent the weakening of friction force size between the 1st and the 2nd follow- up pulley 14,15 and the governor rope 18.

For example when because fracture of main rope 9 etc. and the velocity anomaly of car 3 increases, when the speed that is judged to be car 3 by speed regulation device 57 is unusual, provide the electric power that produces by the 1st, the 2nd electrical generator 55,56 to each emergency braking device 10 from speed regulation device 57.Thus, each emergency braking device 10 work, car 3 stops to move.
In this lift appliance, speed regulation device 57 obtains from the frequency of the voltage of the 1st, the 2nd electrical generator 55,56 information as electric power, judge according to the information of electric power whether the speed of car 3 has unusually, and only when the speed that is judged to be car 3 when being unusual, provide electric power to each emergency braking device 10 from the 1st, the 2nd electrical generator 55,56, so do not need to be used to detect the speed detector of special use of the speed of car 3, just can detect the speed of car 3.Number of components can be reduced thus, cost degradation and miniaturization can be realized.
And, because the 1st and the 2nd follow-up pulley 51,52 separates each other at interval in the horizontal direction side by side,, reduce the size on the short transverse of hoistway 1 so can also reduce the size of pulley gear 54 on short transverse.Thus, can realize the miniaturization of lift appliance.
And, in above-mentioned example, the frequency of speed regulation device 57 working voltages is as the power information of the speed that is used to detect car 3, but so long as the information that changes accordingly with the speed of car 3 gets final product, it also can be voltage swing, in addition, can also on the output of electrical generator, the resistance even load be set to speed regulation device, thus with size of current or frequency as power information.So also can judge whether the speed of cars 3 has unusually, can omit the speed detector of the special use of the speed that is used to detect car 3 by speed regulation device 57.
And in the above-described embodiment, the quantity of the follow-up pulley that will be rotated according to the speed of car 3 is made as these 2 of the 1st and the 2nd follow-up pulleies, is 1 but also can make the quantity of follow-up pulley.Speed regulation device also can be obtained the speed of car 3 according to the rotation of follow-up pulley like this, and whether the speed that can carry out relevant car 3 has unusual judgement.At this moment, governor rope 18 only is wrapped on 1 follow-up pulley.And the application of force by spring 21,22 applies tension force to governor rope 18.
And the quantity that can also make follow-up pulley is more than 3.At this moment, be provided with and the cooresponding handling part more than 3 of each follow-up pulley on the speed regulation device.Whether the speed of carrying out relevant car 3 according to the rotation of pairing follow-up pulley in the reason portion has unusual judgement throughout.And, the speed that in the judgement of each handling part, is judged to be car 3 be unusual quantity than the speed that is judged to be car 3 be normal quantity for a long time, efferent provides electric power from the 1st and the 2nd electrical generator to each emergency braking device 10 when urgent.For example the quantity of follow-up pulley is under 3 the situation, and when the speed that is judged to be car 3 when 2 or 3 handling parts was unusual, speed regulation device provided electric power from electrical generator to each emergency braking device 10.Like this, even have wrong judgement, also can improve the reliability of the judgement of speed regulation device by the judgement of other follow-up pulleies being determined power supply for each emergency braking device 10 for the rotation of a part of follow-up pulley.
And in each above-mentioned embodiment, governor rope 18 is connected with the upper and lower of hoistway 1 respectively by spring 21,22, but also can governor rope 18 only be connected in the upper and lower of hoistway 1 certain by spring.So also can absorb the elongation of governor rope 18 by spring, can prevent the weakening of friction force size of 18 on follow-up pulley and governor rope.
In addition, in each above-mentioned embodiment, pulley gear, emergency braking device, speed regulation device and stand-by circuit only have been installed on car 3, but also they can be installed on the counterweight 4, they can also be installed on car 3 and the counterweight 4 simultaneously.
