Fig. 2 is the top panel 10 formed as mentioned above and the coupled condition of lower faceplate 20.As shown in Figure 2, the spring bar 22 that on the corner of above-mentioned lower faceplate 20, is provided with (22a, 22b, 22c, 22d) be combined into the through hole 14 that connects top panel 10 (14a, 14b, 14c, 14d).In addition, on above-mentioned spring bar 22, be provided for producing separately the retarding spring S of braking force (Sa, Sb, Sc, Sd), these springs are arranged on top panel 10 tops.Be fixed with above the above-mentioned retarding spring S drg P (Pa, Pb, Pc, Pd).Therefore, the spring S that inserts on the above-mentioned spring bar 22 flexibly supports top panel 10 downwards, and the elastic force of these springs S works as braking force in fact.
In the illustrated embodiment, above-mentioned spring S is inserted into spring bar 22, but is not limited to these embodiments, also other elastic devices can be set on the plate in the above, so long as can add that downward elastic force gets final product to above-mentioned top panel 10.
In addition, (32a 32b) engages with ring gear 32 respectively in the upper end of the ball screw 28 that screws tight with spheric nut 26 fixing on the above-mentioned lower faceplate 20.Therefore, when 32 rotations of above-mentioned ring gear, ball screw 28 is also rotated together in fact, and along with the rotation of ball screw 28, fixedly the lower faceplate 20 of spheric nut 26 is up or down removable.
In the middle of above-mentioned a pair of ring gear 32, a sun gear 34 is arranged on the top panel 10.The ring gear 32a and the 32b of above-mentioned sun gear 34 engagement both sides, when above-mentioned sun gear 34 during to a direction rotation, above-mentioned a pair of ring gear 32 rotates mutually round about.That is, in fact when above-mentioned sun gear 34 rotates, ring gear 32 is rotated, rotate ball screw 28 thus, its result can for example move down lower faceplate 20.
The topside of above-mentioned ring gear 32 and sun gear 34 is described below with reference to Fig. 3.As shown in the figure, above-mentioned a pair of ring gear 32 and sun gear 34 tops are provided with axle bearing plate 42.Driven wheel 44 in above-mentioned axle bearing plate 42 is supported by axle 46.Above-mentioned driven wheel 44 bonded assembly axles 46 are connected with above-mentioned sun gear 34.That is, along with the rotation of above-mentioned driven wheel 44, sun gear 34 also rotates.
For example, above-mentioned driven wheel 44 can rotate by actuating devices such as drive motor.And actuating devices such as drive motor obviously also can connect into the axle drive shaft 46 of the above-mentioned driven wheel 44 of direct rotation.
The following describes the embodiment of the actuating device that is used to drive above-mentioned driven wheel 44.
In the axle bearing plate 42 of Fig. 3 pivot shaft 48 is set.As shown in Figure 5, above the above-mentioned pivot shaft 48 the motor accessory is installed, this installation assembled state is shown among Fig. 4.As shown in Figure 4 and Figure 5, engaging with above-mentioned pivot shaft 48 and the motor plate 50 that can rotate freely on, the reductor 54 that is provided with drive motor 52 and is used to make the output of above-mentioned drive motor 52 to slow down.
The above-mentioned reductor 54 inner worm gears that are used to slow down of installing.These reductors itself are known, and can buy on market.And worm gear has the characteristic of high reduction ratio, but can not carry out transmission of power on the reversing sense of transmission of power direction.The power output of slowing down by above-mentioned reductor 54 will be delivered to the output gear 56 that is arranged on above-mentioned motor plate 50 bottom surfaces.And as mentioned above, above-mentioned output gear 56 is engageable with driven wheel 44.
One side of above-mentioned motor plate 50 connects the drive spindle 62 of electromagnet 60.Above-mentioned electromagnet 60 has by the linear structure that moves above-mentioned drive spindle 62 of additional power source.Electromagnet 60 and drive spindle 62 inner structures own are known.
That is, in the action by above-mentioned electromagnet 60, make drive spindle 62 linear when mobile, above-mentioned motor plate 50 is the center with pivot shaft 48, and is rotatable on horizontal surface.For example, under elevator driven state, above-mentioned electromagnet 60 is in on-state, and this moment, above-mentioned drive spindle 62 was pulled to electromagnet 60 sides.Linearity by such drive spindle 62 moves, and above-mentioned motor plate 50 is center anticlockwise direction rotation with pivot shaft 48.When above-mentioned motor plate 50 anticlockwise directions rotate, above-mentioned output gear 56 and driven wheel 44 engagements.
At this moment, above-mentioned drive motor 52 becomes closed condition.That is, above-mentioned drive motor 52 is in closed condition, therefore, even, reductor 54 is added the external force effect, because above-mentioned reductor 54 in-to-in worm gear arrangement can not be reversed motor from driven wheel 44 process output gears 56.
When above-mentioned electromagnet 60 was in off condition, above-mentioned drive spindle 62 extruded motor plate 50 with respect to pivot shaft 48 clockwise directions, had therefore removed the engagement of above-mentioned output gear 56 and driven wheel 44.
The following describes the overall work of elevator car safety of the present invention with said structure.
Elevator by the state of driven under, the top liner plate 12 between above-mentioned top panel 10 and the lower faceplate 20 and bottom liner plate 24 keeps predetermined interval.In addition, the elevator traction rope by (not diagram), does not contact between hauling rope and the top and the bottom liner plate 12,24 between above-mentioned top liner plate 12 and bottom liner plate 24.
In this state, above-mentioned electromagnet 60 keeps conducting state, strains above-mentioned drive spindle 62.Therefore, the engagement of above-mentioned output gear 56 maintenances and driven wheel 44.Under above-mentioned driven wheel 44 and output gear 56 ingear states, above-mentioned spring S compresses top panel 10 downwards like this, and when the elastic force of spring S is done the time spent to top panel 10, lower faceplate 20 moves down in ball screw 28 rotations.But, as mentioned above, bonded assembly ring gear 32 and driven wheel 44 engagements above the ball screw 28, above-mentioned driven wheel 44 is connected with reductor 54 through output gear 56.In addition, because worm gear is installed, can not transmit reciprocal power in the inside of above-mentioned reductor 54.
Therefore, when above-mentioned electromagnet 60 is in conducting state, even drive motor 52 is in closed condition, also impossible reversing sense transferring power, therefore can positively keep between plate 10 and the lower faceplate 20 in the above setting at interval, betwixt the hauling rope of Yi Donging with outside without any friction, thereby can keep normal work.
When such elevator in normal operation abnormal condition takes place, must brake the hauling rope between top panel 10 and the lower faceplate 20.Therefore, when the abnormal elevator working signal was delivered to above-mentioned electromagnet 60, above-mentioned electromagnet was in off state.When above-mentioned electromagnet 60 was in off state, the strength of straining above-mentioned drive spindle 62 disappeared.
Thereby above-mentioned retarding spring S is as powerful to pressing down the application force that compresses above-mentioned ball screw 28 top panel 10 usefulness, and, these application forces come down to act on the spheric nut 26 that is fixed on the lower faceplate 20, as the application force that above-mentioned ball screw is rotated.
In addition, be added in the application force of the retarding spring S of above-mentioned top panel 10, ball screw 28 is rotated, the ring gear 32 that therefore is connected ball screw 28 upper ends also rotates together.By the rotation of above-mentioned ring gear 32, also rotatable sun gear 34, the driven wheel 44 that the rotational force of above-mentioned sun gear 34 links to each other with axle drive shaft 46 tops by axle drive shaft 46 rotations.
When adding rotational force on above-mentioned driven wheel 44, releasing engages with its ingear output gear 56.In more detail, above-mentioned output gear 56 is arranged on below the motor plate 50, and above-mentioned motor plate 50 can support and rotation by supported axle 48.And above-mentioned motor plate 50 is connected with the drive spindle 62 of electromagnet 60, and still, above-mentioned electromagnet 60 has lost the application force of above-mentioned drive spindle 62 tension motor plates 50 because be in off state.Therefore, the rotational force of effect is as the application force utilization of the above-mentioned output gear 56 of rotation on above-mentioned driven wheel 44, but, the motor plate 50 that is provided with on the above-mentioned output gear 56 is because be in free state, the turning effort of above-mentioned in fact driven wheel 44 is extrapolated above-mentioned output gear 56, removes joint between the two.
At this moment, as mentioned above, above-mentioned electromagnet 60 is because be in off state, and the joint of removing above-mentioned output gear 56 and driven wheel 44 is to take place moment.
Therefore, the application force of above-mentioned retarding spring S is by top panel 10 rotary spherical screws 28.Along with the rotation of this ball screw 28, by with the engaging of its lower end screw thread bonded assembly spheric nut 26, lower faceplate 20 moves up.By moving of such lower faceplate 20, lower faceplate 20 and top panel 10 tight joint, above-mentioned top liner plate 12 and bottom liner plate 24 just can be braked hauling rope therebetween.
By said process, the hauling rope that drives elevator stops between top liner plate 12 and the bottom liner plate 24 fully.And the elastic force of above-mentioned retarding spring S should be defined as in the strength scope that can fully stop hauling rope between top liner plate 12 and the bottom liner plate 24.
Therefore, during elevator generation abnormal condition, by the initial elasticity dynamic braking to spring S, lower faceplate 20 and top panel 10 tight joint can fully be braked hauling rope therebetween.
In addition, when stopping elevator like this, restart after must taking appropriate measures.For elevator normally starts again, need separate above-mentioned top panel 10 and lower faceplate 20, make the hauling rope between it be in free state.
For this reason, need make above-mentioned electromagnet 60 and drive motor 52 be in conducting state.That is, when above-mentioned electromagnet 60 and drive motor 52 supply powers were made it to be in conducting state, the drive spindle 62 of above-mentioned electromagnet 60 was tightened up, and was motor plate 50 middle mind-set anticlockwise direction rotation with pivot shaft 48.
Therefore, above-mentioned output gear 56 is by the application force of above-mentioned electromagnet 60, and complete and driven wheel 44 meshes.Then, the rotational force of above-mentioned drive motor 52 rotates above-mentioned output gear 56 through reductor 54.
The rotation of above-mentioned output gear 56 is delivered on the above-mentioned driven wheel 44, and the rotation of above-mentioned driven wheel 44 is delivered on the sun gear 34 through axle 46.When above-mentioned sun gear 34 rotated, the direction that a pair of ring gear 32 of its both sides ingear is opposite was towards each other rotated.The rotation of above-mentioned ring gear 32 is rotated ball screw 28.Along with the rotation of above-mentioned ball screw 28,, lower faceplate 20 is moved downwards by at its lower end bonded assembly spheric nut 26.That is, by the suitable rotation of drive motor 52, above-mentioned lower faceplate 20 leaves top panel 10 and moves downwards, but hauling rope therebetween is in restart mode.And, this restarting when beginning, elevator just can normally turn round.
Below with reference to Fig. 6 the other embodiment of the present invention is described.Illustrated in the top embodiment that reductor 54 uses its inner reductor that worm gears are installed.In addition, by using these reductors that worm gear is installed, can be delivered to output gear 56 to power from drive motor 52 through reductor 54, and not transmit the rotary power from above-mentioned output gear 56 to reductor 54, these are with top described identical.
But, as above-mentioned reductor 54, certainly use the reductor that worm gear is not installed, for example, also can use simple spur gear to carry out to a certain degree deceleration.In addition, when using these reductors,, ball screw 28 is rotated, and pass through the rotation of this ball screw 28, transmission of power is arrived above-mentioned output gear 56 by the strength of lower faceplate 20 being moved to the top of spring S.Therefore, in this case, need have the structure that can prevent above-mentioned output gear 56 counter-rotatings.
In the present embodiment, as shown in Figure 6, the rotary power that drive motor 52 produces is decelerated machine 54 and slows down.At this moment, above-mentioned reductor 54a does not have reductor worm gear, yet can transferring power on reversing sense.
In the above-described embodiment, have below the above-mentioned motor plate 50 by axle 51 wedge members 53 free to rotate, but by spring Sm, wedge members 53 and output gear 56 engagements.And, the flute profile Elastic Meshing of above-mentioned wedge members 53 and output gear 56, but and be arranged on positive dirction rotation (turning effort that drive motor is produced is delivered to the direction of driven wheel 44) and on the position that reversing sense can not rotate.
Therefore, in this embodiment, also can obtain with the identical deceleration of above-mentioned embodiment and prevent the effect of reversing sense transmission of power.In this case, also variable more other various ways of above-mentioned reductor itself.
In the scope that does not break away from basic fundamental thought of the present invention, have the personnel of general knowledge in this area, all can implement other numerous variations.In addition, the present invention should further be explained by the scope of accompanying Claim book.
