Fig. 1 is the main views of showing the door coupling of one embodiment of the invention, also shows the roller 8,9 as door coupling homologue among the figure.Whole door coupling 12 can be directly connected on the car door (containing door strap) by adapter shaft 13,14, also can be connected to door coupling 12 on the supporting plate 3 by adapter shaft 13,14, with screw or other fastening connector supporting plate 3 is fixed on the car door again.Whole door coupling 12 can be the benchmark axle center with adapter shaft 13,14, supporting plate 3 translations relatively.The supporting plate 3 here is completely fixed with car door and is one, and therefore two kinds of above-mentioned mounting meanss there is no substantive difference, and is simple and clear for the convenience of narration, below all is as the criterion with supporting plate 3 and narrates.The clamping element of door coupling is two parallel clamping plate 1,2, its underpart links to each other with connecting rod 5 with 19 by pivot 18 respectively, top is connected on the link rod plate 6 by pivot 16 and 17 respectively, clamping plate 1 can rotate relative to link rod plate 6 and connecting rod 5 around pivot 16,18 respectively, clamping plate 2 can rotate relative to link rod plate 6 and connecting rod 5 around pivot 17,19 respectively, the bottom of connecting rod 5 and link rod plate 6 constitutes two isometric parallel rods from the part the pivot 16 to 17, thereby clamping plate 1,2 and link rod plate 6, connecting rod 5 constitute a parallel-crank mechanism (parallelogram lindage).Door coupling 12 is connected on the driving band 15 by pivot 7, and driving band can be flexible drive parts such as timing belt, silent chain or steel rope.The door engine installation that is fixed on the car drives driving band 15, by the link rod plate 6 of transmission shaft 7 direct level pulling door couplings.Shown in Figure 1 is that a coupling clamping element is in complete open position, and there is suitable gap in clamping plate 1,2 respectively and between the roller 9,8, guarantees that the homologue roller can successfully pass through from the door coupling under the situation without any contact.At this moment, an end is fixed on the supporting plate 3, and the spring 4 that plays clamping action on the other end strap 2 is parallel with connecting rod 5, is in level attitude together, and spring force can not make the parallel-crank mechanism motion along the axis direction effect of connecting rod 5.
When car when certain stop begins to open the door, driving band 15 at first spurs transmission shaft 7, link rod plate 6 is rotated around adapter shaft 13, thereby drive relative supporting plate 3 translations of parallelogram lindage, connecting rod 5 rotates relative to supporting plate 3 around adapter shaft 14, clamping plate 1,2 move to oblique below and oblique upper opposing parallel relative to supporting plate 3 respectively, make clamping plate 1, distance in the middle of 2 begins to reduce, eliminate and roller 8 gradually, the crack also progressively clamps it between 9, until making roller 8,9 relative motions in the horizontal direction are until clamped, after opening the tight element of Room door lock that drives by roller, the clamping element clamping plate 1 of door coupling, 2 with roller 8,9 press into the relative fixed part, and fixedly block piece 10 and movable block piece 11 that link rod plate 6 is installed on the supporting plate 3 are bidirectionally limited.From this moment, the door coupling becomes the complete clamped position that Fig. 2 shows, driving band 5 is further by transmission shaft 7 direct pull link rod plates 6 horizontal motions, is installed in that a door coupling 12 on the car door will drive car door simultaneously and Room door is opened synchronously.Begin to rotate the back from link rod plate 6, make spring 4 no longer parallel with connecting rod 5 because of moving on the clamping plate 2, spring 4 also begins lath 2 is applied power, promotes relatively moving of clamping plate 1,2, makes it to be tending towards to clamp.
Door coupling of the present invention, begin moment of opening synchronously from elevator cab door and Room door, in the process of opening the door of ending to the final position of opening the door, and keep door (car door and Room door) complete opening during, again to door from begin to be closed to the process of closing the door till moment in final position, the door coupling is in closure state shown in Figure 2 always, clamping element clamping plate 1,2 are in the position of complete pinching roller 8,9 always, make the fully simultaneously synchronized operation of car door and Room door, guaranteed concordant fully in whole switch door process of car door and Room door.The power of spring 4 also makes a coupling be kept closed, and helps clamping plate 1,2 pinching roller reliably.
Also can see by Fig. 2, when the clamping plate 1,2 of door coupling are in the state of complete pinching roller 8,9, because fixedly block piece 10 is spacing, make roller 8 and roller 9 not on a plumb bob vertical parallel with clamping plate 1,2, this moment, roller 8,9 still can be respectively rolls along the clamping surface of clamping plate 1,2, explanation is not closed fully at car door and Room door, when a door coupling 12 is in closed clamped condition, allow lift car carry out flat bed or again flat bed move.
When power driven driving band 5 by door coupling pulling car door and Room door behind the terminal location of closing the door, car door and Room door stop motion, the spacing of movable block piece 11 of link rod plate 6 is cancelled, driving band 5 can rotate to the direction of closing the door around adapter shaft 13 by further drivening rod plate 6, link rod plate 6 drives clamping plate 1,2 to mutual open direction translational by parallel-crank mechanism, roller 8,9 also opens gradually in the horizontal direction and resets in this process, lock fully until the tight element of Room door lock that drives by roller, guarantee effectively closing of Room door.Along with progressively opening of clamping clamping plate 1,2, after roller 8,9 resets fully, lath still continues translation and opens until connecting rod 5 and turn to horizontality, this moment, the door coupling was got back to complete deployed position shown in Figure 1 again, the distance of setting thrown off and reaches respectively by clamping plate 1,2 with roller 8,9, guarantee when the lift car setting in motion, can any grazing not take place, and keep the complete open configuration of door coupling to arrive at a station opening the door next time up to lift car with Room door.
What Fig. 3 showed is in the starting stage and the ending phase of closing the door of opening the door, the link rod plate 6 of driving band 5 direct drive door couplings 12 comes closure or openness clamping plate 1,2, in order to unclamp or the process of pinching roller in, clamping plate 1,2 are in roller 8,9 respectively throws off and the critical conditions that contact during moment the constitution diagram of a coupling 12.Also show illustrated position among the figure as the roller 8,9 of door coupling homologue.Fig. 5 has showed that Fig. 3 position gate coupling opens and closes the power transmitting portions, it is the part sectional view that integrates the A-A direction of the part that the transmission connection of switching power and clamping element drive, simple and clear for what observe, spring 4 and fixing element such as block piece 10 do not draw among Fig. 5.Be installed in the power operated driving band 5 on the car, play the link rod plate 6 of the door coupling 12 of connecting rod effect by transmission shaft 7 direct drives, link rod plate 6 drives clamping clamping plate 1,2 relative to supporting plate 3 parallel moving, thereby clamp or unclamp the homologue roller of Room door, and directly by being installed in the door coupling 12 on the car door, drive car door simultaneously and Room door level of synchronization moves, open or close elevator cab door and Room door.The opening and closing of door of the present invention coupling are directly realized by the link rod plate 6 of the driving band 5 driving gate couplings of actuating device, no longer need other any device effect; The switching power of actuating device driving gate also directly affacts on the link rod plate 6 of a coupling, drives car door and Room door simultaneously by the door coupling, makes the designs simplification of total system, and the transmission that opens and closes power is also direct, reliable.
Be necessary explanation a bit, among the door coupling embodiment of the present invention, fixedly block piece 10 and movable block piece 11 are not indispensable part, and spacing if the clamping of the pair roller of Room door homologue of adapted own has, fixedly block piece 10 just can be cancelled; If the application force of spring 4 opposite house couplings 12, the power of driving band 5 driving gate couplings 12 when closing car door and Room door, then movable block piece 11 also can be cancelled.
What Fig. 4 showed is the door coupling of another embodiment of the present invention, wherein, driving band 15 is by transmission shaft 7 pulling connecting rods 106, the parallel-crank mechanism that clamping plate 1,2 and connecting rod 106,5 are formed is relative supporting plate 3 translations in axle center with adapter shaft 13 and 14, the clamping clamping plate 1,2 that drive the door coupling open or closure relatively, after connecting rod 106 relative supporting plates 3 turned to the position that makes clamping plate 1,2 pinching rollers, the block piece 110 and 111 that can be installed on the supporting plate 3 was bidirectionally limited.The upper end of spring is connected to the top of clamping plate 2, and the lower end is connected to the bottom of clamping plate 1, and the power of spring makes the clamping clamping plate l and 2 of a coupling keep open configuration, and an assurance door coupling can be thrown off with Room door roller 8 and 9 during cage operation effectively fully.Be necessary explanation equally, in the embodiments of the invention door coupling, fixing also right and wrong indispensabilities part of block piece 110, spacing if the clamping of the pair roller of Room door homologue of adapted own has, fixedly block piece 110 just can be cancelled.Although the couplet on the door of Fig. 4 and Fig. 1-3 knot utensil has different physical structures, clearly, a coupling that also is applicable to Fig. 4 by door most of functional characters that coupling obtained shown in Fig. 1-3 and advantage.
