Description

BACKGROUND OF THE INVENTION

Technical Field

The present invention relates to an elevator component, in particular to an elevator car door operator device with a car door lock.

Description of Related Art

In the process that an elevator runs up and down, when a car is in flush with a landing, a door vane of a car side door operator usually drives a landing door lock linkage roller on a landing door side to move together to realize the action of opening and closing an elevator door.
Commonly used door vanes include synchronous door vanes and asynchronous door vanes. Synchronous door vanes are a kind of door vanes which firstly clamp the landing door lock linkage roller, and then the car door and the landing door move together. Asynchronous door vanes move simultaneously with the car door, before the car door and the landing door move together, the car door generally has to go a certain distance, and when the door is closed, asynchronous door vanes apply a driving force to the landing door in a door closing direction in advance.
For the asynchronous door vanes, since the car door generally has to firstly go a certain distance before the car door and the landing door move together, there are two main ways in the design of the car door lock. One way is that the rotatable hook of the car door lock is mounted on the suspension part of the car door to realize movement with the car door, the fixed hook is mounted on the door operator cross beam, the unlocking device of the car door lock is mounted on the suspension part of the landing door, and the unlocking device moves with the landing door. In this way, the car door lock must be unlocked by the unlocking device of the suspension part of the landing door before the car door and the landing door move together. Otherwise, once the car door and the landing door move together, the relative speed of the car door and the landing door is zero at this time, and the car door lock can no longer be unlocked by the unlocking device of the landing door. This way is not very convenient in mounting and adjustment, such as in Chinese invention patent application No. CN102015510A .
The other way is that the rotatable hook of the car door lock is mounted on the door operator cross beam and does not move with the car door, the fixed hook is mounted on the suspension part of the car door, the fixed hook moves with the car door, the unlocking device is mounted on the upper sill frame of the landing door, and the unlocking device does not move with the landing door. In this way, although the time that the car door and the landing door move together does not need to be considered, the structure of the car door lock is often complex, it occupies the space of the door operator cross beam, and the cost is relatively high. For example, Chinese invention patent application No. CN101983170A discloses a "Car Door Locking Device for Elevator".
In the above two ways, the car door lock and the asynchronous door vane are independent of each other. The mounting of the car door lock requires to occupy the additional space of the door operator cross beam. Moreover, the additional car door lock unlocking device is often added to the landing side, the cost is high, and the unlocking device arranged on the landing side of a sightseeing elevator affects the attractiveness.
WO2015008386A1 discloses a doorstop-side blade is provided in a car door via a linking mechanism for an elevator car door lock device and can be displaced horizontally between a lock position and an unlock position that is more toward the side opposite of a door pocket. A balance weight is provided on the side opposite of the doorstop-side blade with respect to a rotating shaft of the linking mechanism. By the car door moving to the door pocket side when the car is in a landing position, the doorstop-side blade is displaced by abutting a landing door engaging member and the balance weight is displaced to the side opposite of the doorstop-side blade.

As illustrated in FIG. 5-6, the blocking part 9 on the static part of the elevator door operator cross beam is a steel plate that has been bent for 90 degrees twice. The blocking part 9 has a blocking part mounting surface 51 which is mounting with the static part of the elevator door operator cross beam, a blocking part bending surface 48 which is perpendicular to the blocking part mounting surface 51, and a third surface which is perpendicular to the blocking part bending surface 48 and parallel to the blocking part mounting surface 51. The blocking part mounting surface 51 and the third surface are not on the same plane, but are parallel to each other. Preferably, the side surface of the third surface is the cam line 50 of the cam. When the car door is opened, when the first swinging rod 3 is rotating, the protruding part 13 is in contact with the cam line, and the rotation speed is controlled by the cam line. When the first swinging rod 3 stops rotating, the protruding part 13 is far away from the blocking part 9.
The static part of the above elevator door operator cross beam may be a fixed hook mounting seat 17 as shown in FIG. 7. The fixed hook mounting seat 17 has two mutually perpendicular surfaces, the front surface is parallel to the front surface of the door operator cross beam, the fixed hook mounting seat 17 is mounted on the closing side of the door operator cross beam by using bolts, the bottom surface of the fixed hook mounting seat 17 is perpendicular to the front surface of the door operator cross beam, and two threaded holes are machined in the bottom surface.

As illustrated in FIG. 4, the door vane mounting seat 1 is a plate which is bent for 90 degree, the front surface is parallel to the surface of a door plate, and a side surface perpendicular to the front surface is formed by bending on the door closing side. Circular holes with diameter of 9mm are respectively opened in the upper end and the lower end of the side surface, M8 welding nuts are aligned and welded in the centers of the circular holes, and the welding nuts are on the outer side of the door vane mounting seat. M8 bolts wrapped with rubber at the top ends are used, the length of the bolts is 25mm, the bolts are mounted on the M8 welding nuts, and the positions of the bolts are on the inner side of the door vane mounting seat. The bolts on the upper side and the lower side are a first limiting device 18. The first movable vane 2 has mutually perpendicular surfaces, after the front surface is hinged with the first swinging rod 3 and the second swinging rod 4, the first movable vane 2 is vertical, and when the door is fully closed, the first limiting device is adjusted such that, when the side surface of the first movable vane is in contact with the first limiting device 18, the horizontal gap between the first movable vane 2 and the outer circle of the upper unlocking roller of the landing door lock is set as C1, which may be generally 9mm.
As illustrated in FIG. 3-4, the first swinging rod 3, the second swinging rod 4 and the first movable vane 2 form a double swinging rod mechanism. The gravity of the mechanism enables the first movable vane 2 to swing towards the door opening direction. The pressing applied by the blocking part 9 to the protruding part 13 always causes the first swinging rod 3 to clockwise rotate with the rotating center 36 as a center, and at this time the first movable vane 2 swings towards the door closing direction. When the door is fully closed, the protruding part 13 is pressed against by the blocking part 9, the contact position is the starting end of the cam line 50 of the blocking part 9, and at this time the first movable vane 2 is limited by the first limiting device 18 and cannot continuously swing.
As illustrated in FIG. 21, one M5 threaded hole is machined in the second swinging rod 4, and an elastic element pressing plate device 61 is mounted on the threaded hole. The elastic element pressing plate device 61 comprises an elastic element pressing plate mounting plate 62, a compression spring base 64, and a conical shaft 65. The elastic element pressing plate mounting plate 62 is a steel plate which is bent for 90 degrees and consists of a front surface and a side surface. One circular hole is machined in the front surface. Through the circular hole, the elastic element pressing plate mounting plate 62 is mounted on the M5 threaded hole in the second swinging rod 4. A circular hole with diameter of 5 is machined in the side surface of the elastic element pressing plate mounting plate 62, and the compression spring base 64 is riveted on the circular hole at high speed. The compression spring base 64 is a circular surface, and the circular surface is parallel to the side surface of the elastic element pressing plate the mounting plate 62. The conical shaft 65 is arranged on the compression spring base 64. The center of the conical shaft is concentric with the circle center of the compression spring base 64. The length of the conical shaft is 5mm. An M5 threaded hole is machined in the side surface of the door vane mounting seat horizontally opposite to the elastic element pressing plate mounting plate 62, an M5 screw is mounted on the threaded hole in the side surface of the door vane mounting seat, and the length of the screw may be within 12mm to 16mm. When the door is fully closed, the angle between the side surface of the elastic element pressing plate mounting plate 62 and the side surface of the door vane mounting seat 1 may be set to 10 degrees. One end of the compression spring 63 sleeves the M5 screw, and the other end sleeves the conical shaft to ensure that the first movable vane 2 is not separated from the conical shaft 65 and the M5 screw 60 in the whole maximum swinging process. In the working travel of swinging of the first movable vane 2, the surface of the compression spring base 64 of the elastic element pressing plate is always in contact with the compression spring 63, such that the deformation of the compression spring 63 accumulates or releases energy. When the compression spring 63 releases energy, it pushes the first movable vane 2 to swing towards the door opening direction, and the first movable vane 2 swings towards the door closing direction to enable the compression spring 63 to accumulate energy.
The car door operator has a full closing holding force, which can be provided by a door motor or other mechanical device. When the door is fully closed, even if the first movable vane 2 is pushed towards the door opening direction by the compression spring 63 or the gravity of the mechanism, under the effect of the full closing holding force of the car door, the protruding part 13 of the first swinging rod is pressed against by the lower end of the blocking part 9, and the first movable vane 2 cannot swing towards the door opening direction.
As illustrated in FIG. 14, a notch is opened in the side surface of the door vane mounting seat 1, and the upper edge of the notch serves as a second limiting device 20. When the first movable vane 2 swings towards the door opening direction, the horizontal swinging displacement of the first movable vane 2 is constrained by the second limiting device 20. When the first movable vane 2 cannot continuously swing due to the limiting effect of the second limiting device 20, the vertical movement displacement of the rotatable hook 11 at the end of the first swinging rod 3 is the maximum, and at this time the projection of the rotatable hook and the projection of the fixed hook in the door opening direction overlap. (FIG. 12-15)
As illustrated in FIG. 8-10, when the car door is normally opened in the unlocking area, there are a landing door unlocking roller 28 and a landing door lock linkage roller 29 between the first movable vane 2 and the second movable vane 27. Generally, the outer diameter of the landing door unlocking roller 28 and the outer diameter of the landing door lock linkage roller 29 are the same. Only after the landing door unlocking roller 28 swings for a certain distance of unlocking travel, the landing door unlocking roller cannot swing. At this time the centers of the landing door unlocking roller 28 and the landing door lock linkage roller 29 are on the same vertical line. When the car door is opened, as mentioned above, the first movable vane 2 swings towards the door opening direction. While the car door is opened, the first movable vane 2 swings for a horizontal distance K and then contacts the landing door unlocking roller 28 to continuously open the car door. The first movable vane 2 continuously swings such that the landing door unlocking roller 28 swings towards the landing door lock unlocking direction until the landing door unlocking roller cannot swing. At this time, the centers of the landing door unlocking roller 28 and the landing door lock linkage roller 29 are on the same vertical line. At this time, the acceleration force to push the landing door is far greater than the driving force of the first movable vane 2. The driving force of the first movable vane 2 is the gravity of the double swinging rod mechanism of the first movable vane 2, or the pushing force of the compression spring 63. When the car door is continuously opened, the first movable vane 2 will swing towards the door closing direction by overcoming the driving force under the acceleration reaction force that pushes the landing door. When the car door continuously moves, the first movable vane 2 swings and contacts the first limiting device 18 under the effect of the reverse pushing force of the landing door, and cannot continuously swing. At this time, it can be defined that the door opening travel of the car door is S. At this time, the acceleration force to push the landing door is provided by the first limiting device 18, and the car door and the landing door start to move together.
During the period that the door opening travel of the car door is S, the projection of the rotatable hook 11 and the projection of the fixed hook 16 in the door opening direction do not overlap.
After the car door is opened, the second movable vane 27 starts to swing towards the door closing direction under the effect of the second movable vane action driving device 35. The second movable vane action driving device 35 enables the horizontal swinging displacement of the second movable vane 27 towards the door closing direction after the car door is opened to be S2: S2 = S1-D.
In the above formula, S1 is the distance between the working face of the first movable vane 2 and the working face of the second movable vane 27 when the door is fully closed, D is the horizontal outer width of the landing door unlocking roller 28 and the landing door lock linkage roller 29, and generally in the existing technology, D is the outer diameter of the landing door unlocking roller or the landing door lock linkage roller.
In the actual design, according to the above settings, when the car door is fully closed, the horizontal gap p between the working face of the first movable vane 2 and the outer circle of the upper roller of the landing door lock is 9mm. Through the design of the blocking part 9, the design of the first swinging rod 3, the position relationship between the first rotating center 36 and the first movable vane 2 on the first swinging rod 3, the position relationship between the protruding part 13 on the first swinging rod 3 and the rotating center 36 of the first swinging rod, and the position relationship between the blocking part 9 and the rotating center 36 of the first swinging rod, the unlocking linkage process of the car door and the landing door in the unlocking area is as follows:
When the car door travel is 4mm, the horizontal travel of the horizontal swinging of the first movable vane 2 is 5mm, and the working face of the first movable vane 2 just contacts the outer circle of the landing door unlocking roller 28.
When the car door travel is 7mm, the horizontal travel of the horizontal swinging of the first movable vane 2 is 9mm, and the first movable vane 2 enables the outer circle of the landing door unlocking roller 28 to rotate to a position at which the unlocking travel is the maximum. At this time, the centers of the landing door unlocking roller 28 and the landing door lock linkage roller 29 are on the same vertical line, and the upper roller of the landing door lock cannot continuously rotate. At this time, the reaction force of the acceleration force of the landing door is greater than the sum of the gravity of the first movable vane mechanism and the force in the horizontal direction of the pressing force of the compression spring 63. When the car door is continuously opened, the first movable vane 2 starts to swing towards the door closing direction.
When the car door travel is 16mm, the first movable vane 2 has rotated towards the door closing direction and has contacted the first limiting device 18, the horizontal displacement of the first movable vane 2 compared with the original one is also 16mm, and then the car door and the landing door are opened and closed in a linked manner. In the opening process of the car door, the second movable vane 27 continuously swings towards the door closing direction under the control of the second movable vane action driving device 35, the final horizontal swinging travel is S1-D, and thus the upper and lower rollers of the landing door are clamped.
As illustrated in FIG. 11-17, an M5 threaded hole is machined in the middle of the protruding part 13 on the first swinging rod 3 and the rotatable hook 11, a hoisting rope unlocking device 10 is mounted on the M5 threaded hole, the upper end of the hoisting rope device is a ring and is mounted on the M5 threaded hole machined in the middle of the protruding part 13 and the rotatable hook 11 by using an M5 screw, the ring at the upper end of the hoisting rope device sleeves the M5 screw, and the M5 screw is tightened to fix the upper end of the hoisting rope device.
Relative to the rotating center 36, the hoisting rope device is on the side of the rotatable hook 11. When the hoisting rope is pulled downwards, the first swinging rod 3 rotates such that the first movable vane 2 can clockwise swing by overcoming the pushing force of the elastic element and the gravity of the double swinging rod mechanism. Under the pull of the hoisting rope, the horizontal projection of the rotatable hook 11 in the clockwise direction of the first swinging rod 3 and the horizontal projection of the fixed hook 16 11 do not overlap.
During the period that the door opening travel of the car door is S, the position relationship between the rotatable hook 11 on the first swinging rod 3 and the fixed hook 16 ensures that the first movable vane 2 swings towards the door opening direction. When the horizontal travel of swinging of the first movable vane 2 is S3, the projection of the rotatable hook 11 and the projection of the fixed hook 16 in the door opening direction do not overlap.
The horizontal swinging displacement is S3, which is equal to the horizontal displacement of the first movable vane 2 when the first movable vane 2 pushes the landing door unlocking roller 28 to unlock the landing door and the centers of the unlocking roller 28 and the linkage roller 29 are on the same vertical line.
When the car is not in the unlocking area, there is no unlocking ball at the landing. When the car door is opened, a gap is produced between the protruding part 13 of the first swinging rod 3 and the blocking part 9. The second swinging rod 4 rotates under the pushing force of the elastic element 63, such that the first movable vane 2 swings towards the door opening direction. The first swinging rod 3 rotates when the car door is opened, and the protruding part 13 of the first swinging rod 3 rolls along the cam line 50 of the blocking part 9, such that the rotating speed of the first swinging rod 3 is controlled by the blocking part 9.
When the first swinging rod 3 rotates to a position at which it is limited by the notch 20 in the side surface of the door vane mounting seat:

at this time, the opening travel of car door is smaller than 25mm;
at this time, the rotatable hook 11 has not contacted the fixed hook 16;
at this time, the first swinging rod 3 cannot continuously rotate;
at this time, the first movable vane 2 cannot continuously swing towards the door opening direction;
at this time, the horizontal distance S5 between the working face of the second movable vane 27 and the working face of the first movable vane 2 is smaller than the outer diameter D of the landing door unlocking roller. In design, when D is 46mm, S5 may be 43mm.

At this time, the projection of the rotatable hook 11 and the projection of the fixed hook in the door opening direction overlap. At this time, a connecting line between the circle center of the rotatable hook 11 and the circle center of the cam of the hook head of the fixed hook 16 is the direction of the supporting force provided by the fixed hook to the rotatable hook. The supporting force causes the rotatable hook to produce an anticlockwise torque and the torque causes the first swinging rod 3 to rotate anticlockwise, such that the right side plate of the rotating center of the first swinging rod rotates upwards. But it is blocked by the upper edge of the notch in the side surface of the door vane mounting seat 1, it cannot continuously rotate. When the car door is continuously opened for a certain distance, the rotatable hook contacts the fixed hook when it moves towards the door opening direction.
As illustrated in FIG. 18, the protruding part 13 and the rotatable hook 11 of the first swinging rod 3 and the hoisting rope unlocking device 10 are arranged on the same arm 51, but are not on the same surface. The hoisting rope device and the protruding part 13 are on the same surface of the arm 51. When the first swinging rod 3 moves towards the door opening direction from one side and rotates, the arm 51 can rotate in a space between the back surface of the blocking part 9 and the front surface of the fixed hook 16 without causing interference.
When the car door is opened in the abnormal unlocking area of the elevator, the first swinging rod 2 rotates, and the horizontal displacement direction produced by the protruding part 13 and the rotatable hook 11 during the rotation of the first swinging rod 3 is the door closing direction. The rotating protruding part 13 always rolls along the cam line of the blocking part 9, and the cam line controls the rotating speed of the protruding part 13 and the rotatable hook 11. Through the position relationship among the blocking part 9, the fixed hook 16, the rotating center of the first swinging rod 3, the protruding part 13, the rotatable hook 11 and the first movable vane 2, the design of the cam line 50 of the blocking part 9 and the design of the cam line 52 of the fixed hook, when the door is opened, in the entire rotation process of the first swinging rod 3, the cams of the rotatable hook 11 and the fixed hook 16 have gaps and are not blocked. As illustrated in FIG. 11 and FIG. 12, when the car door travel is 22mm, the cam line 50 of the cam controls the first swinging rod 3 such that the length L1 of the connecting line from the protruding part 13 of the first swinging rod 3 to the center of the rotatable hook is greater than R1+L2. R1 is the radius of the circular shaft of the rotatable hook, and L2 is the distance between the center of the protruding part 13 and the outer end of the cam line of the fixed hook 16 along the direction of the connecting line from the center of the protruding part 13 to the center of the rotatable hook 11.
When the car door is opened to the maximum position in the abnormal unlocking area of the elevator and then the door is closed, the protruding part 13 of the first swinging rod contacts the cam line of the blocking part 9, the cam line of the blocking part 9 is as illustrated in FIG. 5, relative to the vertical line 47 the cam line is inclined towards the door closing side, the protruding part 13 is on the other side of the vertical line 47, the included angle between the tangent part of the cam line 50 and the vertical line 47 is about 3 degrees, and the blocking part 9 in the direction of applying the pressing force to the protruding part 13 always causes the protruding part 13 to generate a clockwise torque M1 to the rotating center of the first swinging rod. In the process that the car door is closed, the protruding part 13 of the first swinging rod 3 is subjected to the pressing force of the cam and always rolls on the cam line. The rotating speed of the first swinging rod 3 is controlled by the car door travel. Finally, when the car door is fully closed, the protruding part 13 returns to the initial position.
As illustrated in FIG. 19-20, when the car is in the unlocking area and requires for emergency rescue, a triangular key is used to open the landing door. When the landing door is opened, the landing door lock linkage roller 29 firstly contacts the second movable vane 27, and the second movable vane 27 is subjected to the pushing force such that the car door is opened. When the car door is opened, the first swinging rod 3 anticlockwise rotates, and the first movable vane 2 swings towards the door opening direction. When the first movable vane 2 swings until it contacts the landing door lock linkage roller 29,
the horizontal travel of the swinging of the first movable vane 2 towards the door opening direction is S4: S4=S1-D.
In the above formula, S1 is the distance between the working face of the first movable vane 2 and the working face of the second movable vane 27 when the door is fully closed, S1 is 72mm here, and D is the horizontal outer width of the landing door unlocking roller and the landing door lock linkage roller.
When the car is in the unlocking area, the car door drives the landing door to move together. When the door is closed, the second movable vane 27 swings towards the door opening direction under the control of the second movable vane action driving device 35 to release the pushing force to the landing door lock linkage roller. In the existing technology, the second movable vane 27 generally releases the pushing force to the landing door lock linkage roller when the car door is at a position with a distance of about 90mm before the door is closed, and the landing door is closed under the effect of the forced door closing force and the initial kinetic energy. Two situations may occur when the door is closed later:
In the first situation, the door closing speed of the landing door is always greater than or equal to the door closing speed of the car door, and the landing door unlocking roller 28 will finally contact the first movable vane 2 and apply a pressing force to the first movable vane 2. When the first movable vane 2 is limited by the first limiting device 18, the speed of the landing door and the speed of the car door are the same, the unlocking roller is always in the unlocked state until the landing door is closed, the first movable vane 2 of the car door operator is far away from the unlocking roller 28, and the landing door unlocking roller rotates towards the locking direction under the effect of its own spring force and gravity, and finally locks the landing door.
In the second situation, the door closing speed of the landing door is smaller than the door closing speed of the car door. At this time, the landing door unlocking roller has a trend of being far away from the first movable vane 2. At this time, the first movable vane 2 rotates towards the door opening direction under the effect of the gravity of the double swinging rod mechanism or the compression spring 63. The horizontal pushing force produced by the compression spring 63 to the first movable vane 2 in the door opening direction should be greater than the horizontal force produced by the landing door unlocking roller 28 during rotation towards the locking direction. The landing door unlocking roller 28 cannot rotate towards the locking direction under the push of the first movable vane 2. Till the protruding part 13 of the first swinging rod 3 contacts the blocking part 9, the first swinging rod 3 enables the first movable vane 2 to rotate towards the door closing direction under the reverse pushing force of the blocking part 9. At this time, the landing door unlocking roller 28 starts to rotate towards the locking direction.
According to the above moment that the car door is opened and the landing door moves together, the travel of the car door S=P+S5=16mm.
P is the horizontal gap between the first movable vane 2 and the landing door unlocking roller when the car door is fully closed, which is 9mm.
S5 is the horizontal travel of the unlocking of the landing door unlocking roller, which is 7mm.
When the car door is closed and the protruding part 13 of the first swinging rod 3 contacts the blocking part 9, the rest of the car door travel from the car door to the fully closed position of the car door is smaller than or equal to S, which is obtained through the following design:

(1) The shape of the cam line of the blocking part 9 and the position relationship between the blocking part 9 and the first swinging rod 3.
(2) The leverage ratio of the first swinging rod 3 and the outer diameter of the protruding part 13. The leverage ratio is the ratio of the distance from the center of the protruding part 13 to the rotating center to the distance from the hinging point of the first movable vane 2 to the rotating center.
(3) The relationship between the horizontal travel of swinging of the second movable vane 2 and the travel of the car door.

Through the above design, the unlocked state of the landing door lock is controlled. When the car door opening travel S or the pre-closing travel S is maintained, the landing door lock is in the unlocked state, so as to prevent the hook of the landing door lock from falling prematurely and the fixed hook of the landing door lock from hitting prematurely.
