Description

Elevator car door machine device with car door lock

Technical field

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

Background technique

During the operation of the elevator up and down, when the car and the landing are leveled, the door door of the car side door machine generally drives the landing door linkage rollers on the side of the landing door to interlock together to realize the action of opening and closing the elevator door.

Commonly used doorknobs include two types of synchronous doorknifes and asynchronous doorknifes. Synchronous doorknob is realized by the door cutter firstly, the action of the clamping layer door linkage roller, and then the car door and the landing door are linked together; the asynchronous door knife moves the door knife and the car door at the same time, before the car door and the landing door are linked, The car door generally has to travel a certain distance first, and the asynchronous door knife will release the driving force of the door in the closing direction in advance when the door is closed.

Asynchronous door cutters Because the car door generally has to travel a certain distance before the car door and the landing door are linked, there are two main ways in the design of the car door lock. One way is to install the rotating hook of the car door lock on the hanging component of the car door, move with the car door moving, the fixing hook is mounted on the door beam, and the unlocking device of the car door lock is installed on the hanging component of the landing door Upper, the unlocking device moves as the landing door moves. In this way, the car door must open the car door lock by means of the unlocking device of the landing door suspension component before the linkage with the landing door, otherwise the car door and the landing door are at a relative speed of zero once the car door and the landing door are linked. The door lock can no longer be opened by the unlocking device of the landing door. This method is not very convenient in installation adjustment, such as the Chinese invention patent application CN102015510A.

Another way is to install the car door lock rotating hook on the door beam to move without moving with the car door. The fixing hook is mounted on the hanging part of the car door, and the fixed hook moves with the movement of the car door, and the floor door is slid An unlocking device is mounted on the frame, and the unlocking device does not move as the landing door moves. In this way, although the car door lock does not need to consider the linkage time of the car door and the landing door, the structure is often complicated, and the space of the door beam is relatively occupied, and the cost is also relatively high. The "car door locking device for an elevator" disclosed in Chinese Patent Application No. CN101983170A.

The outer door unlocking roller 28 and the landing door linkage roller 29 have the same outer diameter. After the door door unlocking roller 28 is swung by a certain distance, the landing door unlocking roller cannot swing, and the landing door unlocking roller 28 and the layer are The center of the door linkage roller 29 is on a vertical line. When the car door is opened, as described above, the first movable blade 2 swings in the door opening direction, and the car door is opened, and the first movable blade 2 is swung by a horizontal distance K and then contacts the landing door unlocking roller 28 to continue to open. The car door, the first movable blade 2 continues to swing, so that the door door layer unlocking roller 28 swings in the direction of the open door lock until the door unlocking roller cannot swing, and the landing door unlocking roller 28 and the landing door linkage roller 29 are The center is on a vertical line. At this time, the acceleration force of the landing door is much larger than the driving force of the first movable blade 2. The driving force of the first movable blade 2 is the gravity of the double swing lever mechanism of the first movable blade 2, and may be the thrust of the compression spring 63. When the car door continues to open, the first movable blade 2 oscillates in the direction of closing the door against the driving force under the action of the acceleration reaction force of the push gate. When the car door continues to move, the first movable blade 2 contacts the first limiting device 18 under the action of the reverse thrust of the landing door, and cannot continue to swing. At this time, the stroke of the car door opening can be defined as S, and then the pushing is performed. The acceleration force of the landing door is provided by the first limiting device 18, and the car door and the landing door start to interlock.

During the time when the car door opening stroke is S, the projection of the rotating hook 11 and the fixed hook 16 in the opening direction does not overlap.

The second movable blade 27 starts to swing in the closing direction by the second movable blade driving device 35 after the car door is opened, and the second movable blade action driving device 35 causes the second movable blade 27 to open in the car door. The horizontal displacement of the swing to the closing direction is S2: S2 = S1 - D.

In the above formula, S1 is the distance from the working surface of the first movable blade 2 to the working surface of the second movable blade 27 when the door is fully closed, and D is the outer width in the horizontal direction of the landing door unlocking roller 28 and the landing door linkage roller 29, generally Prior art D is the outer diameter of the landing door unlocking roller or the landing door linkage roller.

In actual design, according to the foregoing setting, when the car door is fully closed, the horizontal clearance P of the outer circumference of the working surface of the first movable blade 2 and the upper roller of the door lock is 9 mm. By the design of the blocking portion 9, the design of the first swinging rod 3, the positional relationship between the first rotating center 36 and the first movable blade 2 on the first swinging rod 3, the convex portion 13 on the first swinging rod 3 and the first The positional relationship of the swinging center 36 of the swinging rod, the positional relationship between the blocking portion 9 and the center of rotation of the first swinging lever 36, and the interlocking process of unlocking the landing door of the car door in the unlocking area is as follows:

When the car door stroke is 4 mm, the horizontal swing horizontal stroke of the first movable blade 2 is 5 mm, and the working surface of the first movable blade 2 is just in contact with the outer circle of the landing door unlocking roller 28.

When the car door stroke is 7 mm, the horizontal swing horizontal stroke of the first movable blade 2 is 9 mm, and the first movable blade 2 rotates the outer circle of the landing door unlocking roller 28 to the maximum position of the unlocking stroke, at which time the landing door unlocking roller 28 and The center of the lower door lock roller 29 is on a vertical line, and the upper roller of the layer door lock cannot continue to rotate. At this time, the reaction force of the landing door acceleration force is greater than the sum of the gravity of the first movable blade mechanism and the horizontal direction of the thrust of the compression spring 63. When the car door continues to open the door, the first movable blade 2 starts to swing in the opposite direction to the door closing direction.

When the car door stroke is 16 mm, the first movable blade 2 is rotated in the closing direction and has contacted the first limiting device 18. The horizontal displacement of the first movable blade 2 compared with the initial time is also 16 mm, and the rear car door and the layer are The door linkage opens and closes. During the opening process of the car door, the second movable blade 27 continuously swings in the direction of closing the door under the control of the second movable blade motion control device 35, and finally the horizontal stroke is S1-D, and the upper and lower rollers of the landing door are clamped. live.

As shown in FIG. 11-17, the M5 threaded hole is machined in the middle of the first swinging rod 3 and the rotating hook 11 is installed. The pull cord unlocking device 10 is mounted on the M5 threaded hole. The upper end of the pulling device is a ring, and the M5 screw is used. The M5 threaded hole is machined between the boss 13 and the rotating hook 11. The upper end of the cable puller is sleeved on the M5 screw, and the M5 screw is tightened to fasten the upper end of the fixed drawstring device.

Relative to the center of rotation 36, the drawstring device is the side of the swivel hook 11. When the pull cord is pulled downward, the first swing lever 3 is rotated such that the first movable blade 2 swings clockwise against the elastic element thrust and the double swing mechanism gravity. Under the pulling of the drawstring, the horizontal swing projection of the first swing lever 3 in the direction of the pointer and the horizontal projection of the fixed hook 16 do not overlap.

During the period in which the door opening stroke is S, the positional relationship between the rotating hook 11 and the fixed hook 16 on the first swinging lever 3 ensures that the first movable blade 2 swings in the opening direction, and the horizontal stroke when the first movable blade 2 swings is At S3, the projection of the rotating hook 11 and the fixing hook 16 in the opening direction does not overlap.

The swing horizontal displacement is S3: S3 = the first movable blade 2 pushes the layer door unlocking roll 28 to unlock the landing door, and the first movable blade 2 swings when the center of the unlocking roller 28 and the interlocking roller 29 are in a vertical line Horizontal displacement.

When the car is not in the unlocking area, at this time, the landing has no unlocking of the goal ball, and when the car door is opened, the convex portion 13 of the first swinging rod 3 and the blocking portion 9 generate a gap at this time, and the second swinging rod 4 is pushed by the elastic member 63. Rotating downward causes the first movable blade 2 to swing in the door opening direction, and the first swinging lever 3 is rotated while the car door is opened, and the convex portion 13 of the first swinging lever 3 rolls along the cam line 50 of the blocking portion 9. The rotational speed of the first rocker 3 is controlled by the blocking portion 9.

When the first swing lever 3 is rotated to the limit of the side gap 20 of the door cutter mount:

At this time, the stroke of the car door opening is less than 25 mm;

At this time, the rotating hook 11 has not touched the fixing hook 16;

At this time, the first swing lever 3 cannot continue to rotate;

At this time, the first movable blade 2 cannot continue to swing in the direction of opening the door;

At this time, the horizontal distance S5 between the working surface of the second movable blade 27 and the working surface of the first movable blade 2 is smaller than the outer diameter D of the door lock roller. In design, when D is 46mm, S5 can be 43mm.

At this time, the rotation hook 11 overlaps with the projection of the fixing hook in the door opening direction. The center of the rotation hook 11 is now connected with the center of the hook cam of the fixed hook 16 as the supporting force direction of the fixed hook 16 to the rotating hook, and the supporting force causes the rotating hook to generate a counterclockwise torque, which makes the first swing lever 3 Rotate counterclockwise to make the right side plate of the first swing bar rotation center rotate upward, but it is blocked by the upper edge of the side of the door cutter mount 1, and cannot continue to rotate. When the car door continues to open the door for a certain stroke, the rotating hook moves to the door opening direction to contact the fixing hook.

As shown in Fig. 18, the boss portion 13 of the first swing link 3 is disposed on the same arm 51 as the rotary hook 11 and the pull cord unlocking device 10, but not on the same surface. The drawstring device and the raised portion 13 are on the same side of the arm 51. When the first swing lever 3 is moved toward the door opening direction, the arm 51 can be rotated in the space between the back surface of the stopper portion 9 and the front surface of the fixed hook 16 without any interference.

When the car door is opened in the abnormal unlocking area of the elevator, the rotation of the first swing lever 3, the horizontal displacement direction of the convex portion 13 and the rotating hook 11 during the rotation of the first swing link 3 is the closing direction. The turning projection 13 always rolls along the cam line of the blocking portion 9, and the cam line controls the rotational speed of the boss 13 and the rotating hook 11. The design and fixing of the cam line 50 of the blocking portion 9 by the blocking portion 9, the fixing hook 16, the center of rotation of the first swing link 3, the boss portion 13, the rotating hook 11, the positional relationship between the first movable blade 2, and the blocking portion 9. The hook cam line 52 is designed such that when the door is opened, the first swing lever 3 has a gap between the rotary hook 11 and the cam profile of the fixed hook 16 during the entire rotation, and is not blocked. As shown in FIG. 11 and FIG. 12, when the car door stroke is 22 mm, at this time, the cam line 50 of the cam controls the first swing lever 3, so that the length L1 of the first swing lever 3 convex portion 13 to the center of the rotary hook is required. Greater than R1+L2. R1 is the radius of the circular axis of the rotating hook, and L2 is the outer end distance of the cam line of the blocking portion 9 at the center of the convex portion 13 along the center of the convex portion 13 to the center line of the rotating hook 11.

After the car door is opened to the maximum position in the abnormal unlocking area of the elevator, the door is closed. At this time, the first swing lever protrusion 13 contacts the cam line of the blocking portion 9, and the cam line of the blocking portion 9 is relatively vertical as shown in FIG. Line 47, the cam line is inclined toward the door closing side, and the convex portion 13 is on the other side of the vertical line 47. The angle between the tangent portion of the cam line 50 and the vertical line 47 is about 3 degrees, and the blocking portion 9 is opposed to the boss portion. The direction of pressure of 13 always causes the boss 13 to produce a clockwise torque M1 for the center of rotation of the first pendulum. During the process of closing the door of the car door, the convex portion 13 of the first pendulum rod 3 is subjected to the pressure of the cam, which always rolls on the cam line, and the rotation speed of the first pendulum rod 3 is controlled by the car door stroke, and finally the car door is fully When closed, the boss 13 returns to the initial position.

As shown in Figure 19-20, when the car is in the unlocking area and emergency rescue, the door is opened by the triangular key. When the floor door is opened, the lower door lock roller 29 first contacts the second movable blade 27, and the second can be When the moving blade 27 is pushed by the thrust, the car door is opened. When the car door is opened, the first swinging bar 3 rotates counterclockwise, the first movable blade 2 swings in the door opening direction, and the first movable blade 2 swings until it contacts the landing door linkage. Roller 29

The swing horizontal stroke amount of the first movable blade 2 in the opening direction is S4: S4 = S1 - D.

In the above formula, S1 is the distance from the working surface of the first movable blade 2 to the working surface of the second movable blade 27 when the door is fully closed, and 72 mm is taken here, and D is the outer width of the landing door unlocking roller and the landing door linkage roller in the horizontal direction. D is the outer diameter of the landing door unlocking roller or the landing door linkage roller, which is 46 mm.

When the car is in the unlocking area, the car door drives the landing door to interlock. When the door is closed, the second movable blade 27 swings in the door opening direction under the control of the second movable blade action driving device 35 to release the thrust of the landing door linkage roller. In the current technology, the second movable blade 27 releases the thrust of the landing door linkage roller when the car door is closed about 90 mm, and the landing door closes under the action of the forced closing force and the initial kinetic energy. There will be two situations after the closing of the door:

In the first case, the landing door closing speed is always greater than or equal to the car door closing speed, and the landing door unlocking roller 28 will eventually contact the first movable blade 2, applying a thrust to the first movable blade 2, when the first movable When the blade 2 is restrained by the first limiting device 18, the speed of the landing door and the car door are the same, and the unlocking roller is always unlocked until the landing door is closed, and the first movable blade 2 of the car door machine is away from the unlocking roller. 28, the layer door unlocking roller rotates in the locking direction under the action of its own spring force and gravity and finally locks the layer door.

In the second case, the landing door closing speed is less than the car door closing speed, and the landing door unlocking roller generates a tendency to move away from the first movable blade 2, and the first movable blade 2 is in the gravity or compression spring of the double pendulum mechanism. Under the action of 63, the horizontal movable force of the first movable blade 2 in the opening direction of the first movable blade 2 generated by the compression spring 63 should be greater than the horizontal force generated by the rotation of the landing door unlocking roller 28 in the locking direction. The landing door unlocking roller 28 cannot be rotated in the locking direction by the pushing of the first movable blade 2. Until the raised portion 13 of the first swing rod 3 contacts the blocking portion 9, the first swing rod 3 rotates the first movable blade 2 in the closing direction under the reverse thrust of the blocking portion 9, at which time the landing door unlocking roller 28 Start to turn in the lock direction.

According to the aforementioned car door opening and landing door linkage moment, the car door stroke is S=P+S5=16mm

P is a horizontal gap of 9 mm between the first movable blade 2 and the landing door unlocking roller when the car door is fully closed.

S5 is the horizontal stroke of the door unlocking roller unlocking 7mm.

When the car door is closed, when the boss portion 13 of the first swing lever 3 contacts the blocking portion 9, the remaining car door stroke from the fully closed position of the car door is equal to or less than S, which is obtained by the following design:

(1) The outer shape of the cam line of the blocking portion 9 and the positional relationship between the blocking portion 9 and the first swing link 3.

(2) The lever ratio of the first swing lever 3 itself and the outer diameter of the boss portion 13. The lever ratio is a ratio of the center-to-rotation center distance of the boss portion 13 to the distance from the hinge point of the first movable blade 2 to the center of rotation.

(3) The relationship between the horizontal stroke of the swing of the second movable blade 2 and the car door stroke.

Through the above design, the unlocking state of the layer door lock is controlled. When the door opening stroke S or the front door closing stroke S is maintained, the layer door locks are unlocked, and the hooks of the layer door lock are prevented from falling prematurely and the door locks are locked. The fixed hook hits prematurely.
