The height of one or more layers of the building door is lower than that of other layers of the building door when the building door is arranged to meet different building characteristic requirements, such as an interlayer or a door height limit layer by using a bearing beam. When meeting a plurality of landings with different heights, the landing can only be dealt with by a non-standard design engaging device 20 or a method of heightening a door plate/sill of a floor, and the method can cause the opening and engaging area of each floor to be enlarged, thereby bringing potential safety hazards to workers entering and exiting the hoistway. The invention solves the technical problem and provides the elevator car door machine which can be suitable for different floor door heights.

The locking hook 30 is rotatably mounted on the fastening base 21, one side of the locking hook 30 is in abutting fit with the fastening rod 23, and the other side is used for interlocking fit with the lock seat 40. The first driving mechanism 50 is connected to the engaging base 21, and drives the engaging device 20 to move in the height direction of the car. The second driving mechanism 60 is connected to the lock seat 40 for driving the lock seat 40 to move synchronously along the height direction of the car.
It should be noted that the second driving mechanism 60 drives the lock holder 40 to move synchronously in the height direction of the car means that the first driving mechanism 50 drives the engaging device 20 and the lock hook 30 to move synchronously in the height direction of the car, and the second driving mechanism 60 also drives the lock holder 40 to move synchronously in the height direction of the car.
Referring to fig. 1, 2, 4 and 5, when the car reaches the leveling zone, the main control system receives the leveling signal and sends the door opening signal to the door control system, the door control system temporarily stores the door opening command and detects the height of the center of the landing door lock roller 110 of the leveling zone, the height difference between the center of the engaging device 20 and the center of the landing door lock roller 110 is calculated, and the first driving mechanism 50 and the second driving mechanism 60 are instructed to output torque according to the feeding amount, the first driving mechanism 50 drives the engaging device 20 and the locking hook 30 to move, and the second driving mechanism 60 also drives the lock seat 40 to move synchronously until the center height of the engaging device 20 is consistent with the center height of the landing door lock roller. Then, a door opening instruction is called, and the car door moves along the horizontal direction, so that accurate door opening is realized. After passengers or goods enter and exit the lift car, the lift car door is closed. When the car door is completely closed, the car door safety loop is closed, the door control system sends a reset instruction to the first driving mechanism 50 and the second driving mechanism 60, the first driving mechanism 50 drives the fastening device 20 and the lock hook 30 to return to the initial position, the second driving mechanism 60 synchronously drives the lock seat 40 to return to the initial position, then the door closing instruction is transmitted to the main control system, the main control system controls the brake to be released, and the elevator continues to normally operate. Thus, when the heights of the landing doors on all floors are not consistent, the first driving mechanism 50 drives the engaging device 20 and the lock hook 30 to move along the height direction of the car according to the instruction of the door control system, and the second driving mechanism 60 also drives the lock seat 40 to synchronously move along the height direction of the car according to the instruction of the door control system, so that the center height of the engaging device 20 and the center height of the landing door lock roller 110 are always coincident, the centering effect of the landing door lock roller 110 relative to the engaging device 20 in the vertical height during door opening and closing is ensured, and the use safety of the elevator is improved. Meanwhile, the tying rod 23 does not need to be lengthened to correspond to different landing door heights, the parallelism of the tying rod is better controlled, and the mutual collision between the tying rod and the landing door lock roller during the operation of the elevator caused by the fact that the distance between the tying rod and the landing door lock roller is too small is avoided. In addition, when the height of the top floor is not enough, and the central height of the landing door lock roller 110 is greater than the central height of the fastening device 20, the first driving mechanism 50 can drive the fastening device 20 and the lock hook 30 to move along the height direction of the car, and the second driving mechanism 60 can drive the lock holder 40 to move along the height direction of the car, so that the fastening device 20, the lock hook 30 and the lock holder 40 do lifting movement, and the door is opened and closed.
Referring to fig. 6 and 7, it should be noted that the central height of the fastening device 20 is the height of the middle position of the fastening rod 23 of the fastening device 20 in abutting engagement with the latch hook 30, and is H1Indicating the center height of the hitch 20. The center of the layer door lock roller 110 is the height of the central position of the layer door lock roller, and H is adopted2Indicating the center height of the landing door lock roller 110.
In one embodiment the elevator car door opener further comprises a transmission 10. The transmission mechanism 10 is connected to the first driving mechanism 50 and the second driving mechanism 60 respectively, and can drive the first driving mechanism 50 and the second driving mechanism 60 to move towards or away from each other. In this way, a door opening instruction is called, and after the latch hook 30 is separated from the latch holder 40, the transmission mechanism 10 drives the first driving mechanism 50 and the second driving mechanism 60 to move back to back, so that the door opening is facilitated; when a door closing command is called, the transmission mechanism 10 drives the first driving mechanism 50 and the second driving mechanism 60 to move in opposite directions, so that the hook lock 30 and the lock seat 40 are interlocked, and the door is closed.
In this embodiment, the transmission mechanism 10 includes a first pulley assembly and a second pulley assembly, the first driving mechanism 50 is connected to the transmission belt on one side of the first pulley assembly, and the second driving mechanism 60 is connected to the transmission belt on one side of the second pulley assembly.

In one embodiment, referring to fig. 1 and 2, the first drive mechanism 50 is a first linear motor. Specifically, the first driving mechanism 50 includes a first mover 51 and a first stator 52, the first stator 52 is fixedly connected to the transmission mechanism 10, and the first mover 51 is fixedly connected to the engaging base 21 and is movable in the height direction of the car in cooperation with the first stator 52. Alternatively, the first mover 52 is a short primary and the first mover 51 is a long secondary. When the lift car reaches a leveling zone, the height position of the center of the landing door lock roller 110 of the leveling zone is detected, the height difference between the center of the engaging device 20 and the center of the landing door lock roller 110 is calculated, the first stator 52 is instructed to be matched with the first stator 51, the engaging device 20 and the lock hook 30 are driven to move along the height direction of the lift car until the landing door lock roller 110 achieves the centering effect relative to the engaging device 20, and accurate door opening is facilitated. Thus, the first rotor 51 and the first stator 52 are matched to drive the engaging device 20 and the locking hook 30 to move linearly in the height direction of the car, and the elevator car locking device is simple in structure, high in movement precision and free of backlash.
Of course, in other embodiments, the first driving mechanism 50 may also be a pulley assembly, such as a belt fixedly connected to the pulley assembly with the base 21. Alternatively, the first driving mechanism 50 may be a lead screw module, which is fixedly connected to the lead screw nut by the base 21.
Further, referring to fig. 1 and 2, the engagement base 21 is fixed to a bottom of the first mover 51.

Specifically, the second driving mechanism 60 includes a second mover 61 and a second stator 62, the second stator 62 is fixedly connected to the transmission mechanism 10, and the second mover 61 is fixedly connected to the lock base 40 and can move in the height direction of the car in cooperation with the second stator 62. Alternatively, the second stator 62 is a long primary and the second mover 61 is a short secondary. When the lift car reaches a leveling zone, the height position of the center of the landing door lock roller 110 of the leveling zone is detected, the height difference between the center of the combining device 20 and the center of the landing door lock roller 110 is calculated, and the second stator 62 is instructed to be matched with the second rotor 61 to drive the lock seat 40 to move to a target position along the height direction of the lift car, so that accurate door opening is facilitated. Therefore, the second rotor 61 and the second stator 62 are matched to drive the lock seat 40 to move linearly along the height direction of the car, and the elevator car locking device is simple in structure, high in movement precision and free of backlash.
Of course, in other embodiments, the secondary drive mechanism 60 may also be a pulley assembly, such as a belt with the lock housing 40 fixedly attached thereto. Alternatively, the second driving mechanism 60 may be a lead screw module, and the lock base 40 is fixedly connected to the lead screw nut.
Further, the second linear motor is flat, and the second linear motor is a double-sided linear motor. It should be noted that, stators are disposed on both sides of the mover of the double-sided linear motor, the double-sided linear motor can generate a double-sided magnetic field, and normal suction forces between the stators and the mover can be cancelled out. Because the second pulley component and the lock seat 40 of the transmission mechanism 10 are arranged in a front-back manner, the double-sided linear motor is more beneficial to uniform stress.
In one embodiment, the elevator car door machine further includes a distance measuring sensor for detecting the height position of the center of the landing door lock roller 110 for each floor zone. Therefore, the height difference between the center of the binding device 20 and the center of the landing door lock roller 110 can be conveniently calculated, the feeding amount of the first driving mechanism 50 and the second driving mechanism 60 can be instructed, the central height of the binding device 20 is ensured to be consistent with the central height of the landing door lock roller 110, and accurate door opening is realized.

The second driving mechanism 60 is fixed on the second car hanging plate 80, and the lock seat 40 is fixed on the output end of the second driving mechanism 60. In this way, the first car hanging plate 70 and the second car hanging plate 80 provide mounting positions for the first driving mechanism 50 and the second driving mechanism 60, and the first driving mechanism 50 and the second driving mechanism 60 are convenient to mount.
