The first blade rotating arm 53 and the second blade rotating arm 54 are respectively hinged and fixed on the front face of the U-shaped plate 11, the first blade 51 and the second blade 52 are respectively hinged with the first blade rotating arm 53 and the second blade rotating arm 54 to form a parallelogram connecting rod structure, the first blade rotating arm 53 is connected with one end of a second connecting arm 55, and the other end of the second connecting arm 55 is connected with the other end of the connecting shaft 24.
The plate 61 is a plane plate, and the grooves at the two ends of the plate 61 are respectively inserted into the grooves of the release arm component 3 and the latch hook component 4. The catching end of the guide shaft 62 is inserted into the groove of the rotating plate 21.
The rotating plate component 2 is connected with a transmission belt of the elevator car door device, and the synchronous belt shaft 23 of the rotating plate component 2 is driven to move through the elevator car door device.
The release arm assembly 3 lifts the release shaft 31 to unlock through the release plate 7 fixed on the elevator door device, so that the rotating plate assembly 2 can act, at the moment, the spring 63 in the release device 6 starts to act, and the elevator door device is pushed to exert a holding force in the door closing direction through the invention. The door closing holding force is provided at the initial stage of the pivotal plate 21 and can be removed when the timing belt shaft 23 of the pivotal plate assembly 2 is pivoted to the right side of the first slot hole 111 of the U-shaped plate 11. While the release arm assembly 3 also provides a door closing retention force by virtue of the release plate 7 on the door closing side. The two-stage retention force of the system can solve the phenomenon of 'secondary door closing', and can reduce the load of the elevator car door device driving system increased by the secondary door closing phenomenon after the door is closed in place.
When the initial position of the synchronous belt shaft 23 of the rotating plate assembly 2 is at the left side of the first slot hole 111 of the U-shaped plate 11, the guide shaft axis 65 is positioned above the reference line 66 formed by the connection of the center of the fixed shaft bearing of the rotating plate assembly 2 and the center of the circular hole of the plate 61. When the synchronous belt shaft 23 is driven to the right side of the first slot hole 111 of the U-shaped plate 11 by the elevator car door device, the buckling end of the guide shaft 62 rotates by taking the groove of the rotating plate 21 as the center, and the cutter arm assembly 5 is driven to act through the connecting shaft 24. The guide shaft axis 65 finally passes through the reference line 66 to reach below the reference line 66, and the angle between the guide shaft axis 65 and the reference line 66 is greater than 0 °. When the axis 65 of the guide shaft is positioned below the datum line 66, the force of the spring 63 released due to unexpected power failure cannot be released, so that the knife arm assembly 5 cannot act, and the potential safety hazard that the door lock ball of the landing door is damaged by blade impact after the elevator is electrified again or when the barring rescue returns to the leveling floor is eliminated.
The states of the invention in the process of opening and closing the door in the flat zone are as follows: the rotating plate assembly 2 is locked by the releasing arm assembly 3 and cannot rotate, so that the synchronous belt shaft 23 stays on the left side of the first slotted hole 111 of the U-shaped plate 11, the connecting shaft 24 cannot move downwards, meanwhile, a door ball of a door lock on the layered door side of the elevator flat layer acts on the first blade 51 and the second blade 52, the two blades cannot be excessively expanded outwards, and the second connecting arm 55 cannot move upwards. Therefore, the position of the connecting shaft 24 is limited by the rotating plate assembly 2 and the knife arm assembly 5, and finally the connecting shaft acts on the locking hook assembly 4 to enable the head of the locking hook assembly to be lifted so as to be in an unlocking state. The guide shaft axis 65 of the release device 6 is now above the reference line 66.
The process of the invention for closing the door in place comprises the following steps: the release arm assembly 3 is acted upon by the release plate 7 at the door-closing end, and finally the release shaft 31 is lifted to the door-closing side of the release plate 7. The pivotal board assembly 2 is not locked by the release arm assembly 3, and the timing belt shaft 23 is pivoted from the left side of the first slot 111 of the U-shaped board 11 to the right side of the first slot 111, and during the pivoting, the first link arm 22 is moved downward, and the link shaft 24 is moved along the second slot 112 of the U-shaped board 11. In addition, the second connecting arm 55 moves along with the connecting shaft 24, so that the first blade 51 and the second blade 52 are folded, meanwhile, the locking hook assembly 4 is separated from the limit of the connecting shaft 24, and the head of the locking hook assembly 4 downwards reaches a locking position under the action of gravity and the spring 63.
At this time, if the two blades are subjected to the acting force in the retracting direction again, the second connecting arm 55 is actuated, but the rotating plate 21 cannot be actuated, and the first connecting arm 22 can only rotate with the connection point of the first connecting arm and the rotating plate 21 as the base point, so that the connecting shaft 24 is pushed to move towards the latch hook assembly 4, and the head of the latch hook assembly 4 is lifted up to be in the unlocking state. The car door can be locked outside the elevator flat zone, and the door plate can be opened inside the car or outside the landing door during flat zone, so that rescue is facilitated, and finally the function of the car door lock is realized.
After the door is closed to a certain position, the plate 61 is pushed by the force of the spring 63, so that the release arm assembly 3 is rotated, and the release shaft 31 pushes the release plate 7 to generate a holding force in the door closing direction. Meanwhile, the synchronous belt shaft 23 is driven by the elevator car door device, and rotates from the left side of the first slotted hole 111 of the U-shaped plate 11 to the right side of the first slotted hole 111 after overcoming the acting force of the spring 63, and the acting force pushing to the door closing direction is also generated in the process, and the two acting forces can solve the phenomenon of 'secondary door closing' together. Meanwhile, during the door closing action of the door locking knife, the timing belt shaft 23 rotates from the left side of the first slot hole 111 to the right side of the first slot hole 111, and the guide shaft axis 65 of the release device 6 travels from above the reference line 66 to below the reference line 66. No matter whether the elevator has electricity or not, acting force is generated to enable the rotating plate assembly 2 to rotate, and the synchronous belt shaft 23 is guaranteed to be arranged on the right side of the first slotted hole 111, so that false operation caused by electricity loss of the elevator can be avoided for the two blades, and the potential safety hazard that the door lock ball of the landing door is damaged by blade impact after the elevator is electrified again or when the barring rescue returns to the leveling floor is eliminated.
