Since adapter plate 279 contiguous spiral plates 277, and face cam 278 is rotated, therefore, if desired, can be integrally formed with spiral plate 277.Auxiliary clutch disc bar 220-1 is arranged on the top of clutch disc plate 220, to help the separation of vertical clutch disc 211, and be hinged to clutch disc 211, make clutch disc 211 separate with clutch disc 210 by clutch disc link pin 212 movable fixed.
As Fig. 5, Fig. 6 and shown in Figure 7, for elevator door system of the present invention with said structure, when opening elevator inlet the passenger and climbing up during car begins between lifting after the car vertically when mobile, the clutch disc 210 of car door shown in Figure 7 and 211 promotes between the rollers 125 and 142 at first and second of Fig. 5 and stop door shown in Figure 6.Under this state, during releasing the button in pressing car, maybe when by being used for and during operating electrical machines 271, automotive V-belt 281 moves along direction shown in the arrow, to open stop door holding plate 201 from the order of external opening elevator inlet.When vertical clutch disc 211 is in the motion, face cam 250 moves to the position of second cam path 252 from the position of first cam path 251, and face cam bar 260 rotates in the counterclockwise direction, as Fig. 8 and shown in Figure 9, therefore, vertically clutch disc 211 and Fig. 8 separate a preset distance with fixing vertical clutch disc 210 shown in Figure 9.
Before above-mentioned state, the promotion of first among Fig. 5 and Fig. 6 roller 125 is promoted to the right by the fixing vertical clutch disc 210 of Fig. 7, makes hook rod 120 rotate in the counterclockwise direction around link pin 121, therefore, and hook protrusion 122 and dog hole 131 disengagings.Therefore, stop door 100 is opened to state shown in the long and short dash line among Fig. 5.Like this, when first promoted roller 125 and promoted to the right, stop door 100 was opened to both sides.Reason is that because the stop door holding plate 110 on right side is fixed on the below of cable wire 105, the stop door holding plate 110 in left side is fixed on the top of cable wire 105, and cable wire 105 moves in the counterclockwise direction, to open stop door 100.After the initial open operation of above-mentioned elevator door system, in the middle opening stage of door, the open operation of door system is changed into state shown in Figure 8 from state shown in Figure 7.Promptly, when face cam bar 260 during near the vertical position of switch shafts 262, face cam bar 260 rotates in the counterclockwise direction around cam link pin 253, therefore, when cam rollers 240 contacts second cam path 252, clutch disc bar 220 rotates in the counterclockwise direction around clutch disc bar link pin 214.Because clutch disc bar 220 is fixed to clutch disc bar stay bearing plate 230 (car door holding plate 201) by clutch lever link pin 214 in heart place therein movably, and also be fixed to vertical clutch disc 211 movably at its lower end, therefore vertically clutch disc 211 separates with clutch disc 210, as shown in Figure 8.Certainly, the degree of separation and Fig. 5 and first and second gaps that promote between the rollers 125 and 142 shown in Figure 6 are corresponding.
The present invention has and is characterised in that, after door was opened to as shown in Figure 8 predetermined extent, the closing velocity of door reduced, and guaranteeing passenger's safety, thereby avoids the passenger to be stuck between the door.For this purpose, elevator door system comprises acceleration-deceleration cam C as shown in figure 11.Each acceleration-deceleration cam C all has an inclination cam part 278-5 at the interface between the large-diameter portion 278-4 of face cam 278 and minor diameter 278-3, to drive relevant limit switch 276, this limit switch 276 has the removable load 276-1 that is connected to inclination cam part 278-5.Therefore, as shown in figure 11, acceleration-deceleration cam C is used to detect open position, off position and the acceleration-deceleration position that has out of phase respectively.For example, when as shown in figure 11 relevant removable load 276-1 of the end of the large-diameter portion 278-4 of each acceleration-deceleration cam C1 contact, handle relevant limit switch 276 so that the position of controller (not shown) identification acceleration-deceleration cam makes its expression door closure state.Equally,, must discern the position of acceleration-deceleration cam C2, be about to close the order of closing deceleration before (under this situation, as acceleration-deceleration cam C1, the end of the major diameter part 278-4 of acceleration-deceleration cam C2 contacts the relevant removable load 276 of related switch SW2) as the expression door, must discern the position of acceleration-deceleration cam C3, be used to open the order of deceleration as expression, and must discern acceleration-deceleration cam C4, as the open mode of door.For this purpose, acceleration-deceleration cam C is installed on the axle 262 with out of phase.
Especially, the advantage that the present invention has is, in each acceleration-deceleration cam C, be formed with the face cam 278 that radially cock plate 277 contacts of faucet hole 277-1 are formed with elongated hole 278-1, make the phase angle of adjusting cam dish 278 (position of major diameter part 278-4 and small diameter portion 278-3) easily, and keep this phase angle by the control screw rod 278-2 that passes the hole.Thereby, when car door is opened, face cam bar 260 as shown in Figure 7 rotates along clockwise direction, and switch element 275 is rotated (in this case in the counterclockwise direction, face cam bar 260 is integrally operated in the outside (right side) of the upper end of the switch shaft 262 of Figure 11), and under state as shown in Figure 7, the end of the major diameter part 278-4 of the acceleration-deceleration cam C1 of Figure 11 promotes the removable load 276-1 of relevant limit switch 276, to connect controller.In addition, as shown in Figure 8, when the elevator inlet is in the following time of state of soon being opened fully, the end of the large-diameter portion 278-4 of the acceleration-deceleration cam C3 of Figure 11 promotes the removable load 276-1 of related switch SW3, to operate relevant limit switch 276 (in Figure 11, as can be known, although be not in the promotion state, acceleration-deceleration cam C operates with the phase place identical with the rotation of switch shaft 262).Afterwards, connect the controller (not shown) detecting this state, and send deceleration command, so that switch element 275 is closed when car door slows down to motor 271 as shown in Figure 8.
When door is opened as shown in figure 10 fully, switch shaft 262 rotates, the switch element 275 that is in closed condition is as shown in figure 11 handled, make the end of large-diameter portion 278-4 of acceleration-deceleration cam C4 of Figure 11 promote the removable load 276-1 of relevant switch SW 4, to handle relevant limit switch 276.Afterwards, controller detects opening fully of going out, and stops motor 271.Simultaneously, according to the present invention, bob-weight 262 is arranged on the upper end of face cam bar 260, and be provided at the additional function that the initial and final stage that opens or closes door reduces motor 275 power, thereby, allow the pulsation-free opening/closing, improve the durability of elevator door system simultaneously.
According to the present invention, and, also can carry out the shutoff operation of elevator door system according to same principle of work.That is, the closing velocity of door is lower at initial dwell period as shown in figure 10, and is increased during the stage at closed center.When door is in as shown in Figure 8 following time of state, vertically clutch disc 211 promotes second roller 142 to close door, and, make clutch disc 211 reduce naturally with respect to second driving velocity that promotes roller 142 because manipulation face cam 250 reduces the distance between clutch disc 210 and 211.According to the present invention, switch element 275 leaves as shown in Figure 8 state together with being connected to each other by manipulation between face cam 250 and the face cam bar 260, therefore, the end of the large-diameter portion 278-4 of the acceleration-deceleration cam C2 of Figure 11 promotes the movably load 276-1 of the relevant switch SW 2 of limit switch 276.As a result, controller reduces the speed of motor 271, reducing the last closing velocity of door, thereby, avoid being stuck in accident between the car door 200 of closing such as finger.In this case, when closing stop door 100, the tension force of extension spring 113 is applied to stop door 100 by return load 112, makes stop door 100 close naturally by roller 110.Thereby, not having under the situation of extra power, stop door 100 is closed.When stop door 100 was closed fully, the hook protrusion was hooked on the dog hole 131 of hook-type fish plate 130, and the stop door is remained in stop ground framework 103, thereby, avoided accident.
When closing car door 200, auxiliary stop 290 contact stopping rollers 293, and as hill holder.In this, because auxiliary stop 290 comprises angled cam 291-1,291-2 and 291-3, therefore provide the friction that repeats as drg ABS system in the vehicle, it can be used as level and smooth and crash-resistant hill holder.Provide elastic force owing to support the roller holding plate 294 of stopping roller 293 by the stopping roller 293 of spring 297 around the adapter plate hinge 295 that is arranged on roller holding plate center that is arranged on its other end, therefore, this effect can realize.When door was closed fully, off switch pusher 286 promoted and connects off switch 287, fully to stop motor 271.
Although for illustrative purpose has disclosed the preferred embodiments of the present invention, but for those skilled in the art, should be appreciated that under the situation that does not deviate from disclosed principle of the present invention of claims and spirit, various modifications can be arranged, add and be equal to replacement.
