Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and in particular to a car door lock device and an elevator. Background Technology

[0002] With the development of electrical equipment technology, the number of old elevators in China that have been in service for more than ten or even several decades has become enormous, and they urgently need to be upgraded and renovated. When upgrading old elevators, based on considerations such as cost, construction period, and performance improvement, the usual approach is to retain the landing door components and replace the car door components. This involves the matching problem between the replaced car door side components and the retained landing door side components, mainly manifested in the matching problem between the car door locking device and the landing door locking device.

[0003] However, due to the large number of old elevator brands and the different structural dimensions between the landing door lock rollers, different car door lock devices need to be designed separately to match the various landing door lock devices. This makes it impossible to implement standardized design, and the design cycle is long, making it difficult to promote and use. Summary of the Invention

[0004] Therefore, it is necessary to provide a car door lock device and an elevator to address the compatibility issue between the car door lock device and landing door lock devices of different sizes.

[0005] A car door lock device, comprising:

[0006] A gantry crane frame, on which a first door hanging plate and a second door hanging plate are movably mounted;

[0007] The base is fixed to the first door hanging plate, which is used to connect the first car door and the second door hanging plate is used to connect the second car door. The first door hanging plate and the second door hanging plate can move away from each other to allow the car door locking device to enter the open state, which separates the first car door from the second car door; the first door hanging plate and the second door hanging plate can also move closer to each other to allow the car door locking device to enter the closed state, which closes the first car door from the second car door.

[0008] A clamping wheel door knife, wherein the clamping wheel door knife is pivotally mounted on the base;

[0009] A knife-lifting assembly is disposed on the gantry frame, which enables the clamping wheel gantry knife to swing upward;

[0010] The door unlocking knife is mounted on the base and is located on the side of the clamping wheel door knife near the second door hanging plate. A gap is formed between the door unlocking knife and the clamping wheel door knife to accommodate the landing door lock roller assembly. During the switching process between the open and closed states of the car door lock device, the clamping wheel door knife and the door unlocking knife can jointly clamp the landing door lock roller assembly.

[0011] A blocking plate, which is detachably mounted on the gantry frame;

[0012] A blocking wheel is rotatably mounted on the clamping wheel door knife; when the clamping wheel door knife and the unlocking door knife clamp the door lock roller assembly together, the blocking wheel can cooperate with the blocking plate to limit the upward swing of the clamping wheel door knife.

[0013] The technical solution will be further explained below:

[0014] In one embodiment, the gantry frame has a plurality of spaced mounting holes, the blocking plate has a connecting hole, and a threaded connector is inserted into the connecting hole, the threaded connector being threaded to any of the mounting holes.

[0015] In one embodiment, the blocking plate includes a connecting part that is detachably fixed to the door operator frame. The connecting part has a slotted hole, and the door operator frame has a mounting hole that aligns with the slotted hole. The car door lock device also includes a threaded connector that passes through the slotted hole and is movable along the slotted hole. The threaded connector is threadedly engaged with the mounting hole.

[0016] In one embodiment, the car door lock device further includes a connecting component, one end of which is rotatably connected to the base, and the other end is rotatably connected to the clamping wheel door knife via the connecting shaft, wherein the blocking wheel is rotatably disposed on the connecting shaft.

[0017] In one embodiment, the knife-lifting assembly includes a knife-lifting groove disposed on the top of the gantry frame and extending upward toward the top of the gantry frame. The top of the clamping wheel knife extends above the top of the gantry frame and is rotatably provided with a knife-lifting roller, which can roll and engage with the knife-lifting groove.

[0018] In one embodiment, the lifting groove is an arc-shaped structure, with the center of the arc located on the side where the lifting roller is located.

[0019] In one embodiment, the car door lock device further includes a car door lock hook and a lock head. The door unlocking knife is pivotally mounted on the base. The car door lock hook is rotatably mounted on the base and is located on the side of the door unlocking knife near the second door hanging plate. The lock head is fixed on the door operator frame. The door unlocking knife can drive the car door lock hook to connect with the lock head to lock the car door lock device in the closed state. The door unlocking knife can also drive the car door lock hook to separate from the lock head to release the lock on the car door lock device.

[0020] In one embodiment, according to claim 7, the car door lock device has an unlocking roller rotatably provided on the side of the car door lock hook near the unlocking door knife, and the unlocking door knife abuts against the unlocking roller.

[0021] In one embodiment, the car door lock device includes a first limiting member and a second limiting member, which are disposed on the base. The first limiting member is located in the gap formed between the unlocking door knife and the clamping wheel door knife, and the second limiting member is located on the side of the unlocking door knife near the second door hanging plate.

[0022] An elevator, comprising the car door locking device as described in any one of claims 1 to 9.

[0023] The aforementioned car door lock device and elevator, by installing a clamping wheel door knife and an unlocking door knife on the base and a lifting knife assembly on the top of the door operator frame, allow the clamping wheel door knife and the unlocking door knife to jointly clamp the landing door lock roller assembly during the switching between the open and closed states of the car door lock device. This maintains a fixed relative position between the car door and the landing door, preventing them from moving around during the switching process and avoiding accidents such as the landing door failing to close, which could endanger the safety of passengers inside the elevator. Furthermore, because it is detachable... A baffle plate is installed on the landing door so that when the landing door is obstructed from closing and the door clamping wheel needs to apply closing force to the landing door lock roller assembly, the baffle plate can restrict the lifting of the door clamping wheel by pressing against the blocking wheel, thereby preventing the door clamping wheel from releasing the landing door lock roller assembly, and thus preventing the car door and landing door from moving around each other, reducing safety risks. Furthermore, since the baffle plate is detachable, its position and structure can be set according to different landing door lock device sizes and structures, thereby improving design efficiency, reducing response time, and making it more suitable for widespread application in the renovation of old elevators.

[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0043] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0044] like Figure 1As shown in the figure, an embodiment of this application provides a car door lock device, which includes a door operator frame 1, a base 2, a clamping wheel door knife 21, a lifting knife assembly, an unlocking door knife 24, a blocking plate 13, and a blocking wheel 212. A first door hanging plate 10 and a second door hanging plate 11 are movably mounted on the door operator frame 1. The base 2 is fixed to the first door hanging plate 10, which connects to the first car door, and the second door hanging plate 11 connects to the second car door. The first door hanging plate 10 and the second door hanging plate 11 can move away from each other to allow the car door lock device to enter an open state, separating the first and second car doors. The first door hanging plate 10 and the second door hanging plate 11 can move closer to each other to allow the car door lock device to enter a closed state, closing the first and second car doors. The clamping wheel door knife 21 is swayably mounted on the base 2. The lifting knife assembly is mounted on the door operator frame 1, allowing the clamping wheel door knife 21 to swing upwards. The unlocking door knife 24 is mounted on the base 2, located on the side of the clamping wheel door knife 21 near the second door hanging plate 11. A gap is formed between the unlocking door knife 24 and the clamping wheel door knife 21 to accommodate the landing door lock roller assembly 3. During the switching between the open and closed states of the car door lock device, the clamping wheel door knife 21 and the unlocking door knife 24 can jointly clamp the landing door lock roller assembly 3. A blocking plate 13 is detachably mounted on the door operator frame 1. A blocking wheel 212 is rotatably mounted on the clamping wheel door knife 21. When the clamping wheel door knife 21 and the unlocking door knife 24 jointly clamp the landing door lock roller assembly 3, the blocking wheel 212 can cooperate with the blocking plate 13 to limit the upward swing of the clamping wheel door knife 21.

[0045] It should be noted that, for reference Figure 1 and Figure 2 When the clamping door knife 21 and the unlocking door knife 24 clamp the landing door lock roller assembly 3 together, the blocking plate 13 and the blocking wheel 212 can be configured to be in contact or in clearance. This configuration ensures that when the landing door is obstructed from closing and the clamping door knife 21 needs to apply closing force to the landing door lock roller assembly 3, the blocking plate 13 can limit the lifting of the clamping door knife 21 by pressing against the blocking wheel 212. When the bottom of the blocking plate 13 is in clearance with the blocking wheel 212, it can still be used normally, and it can also avoid the blocking wheel 212 from being in contact with the blocking plate 13 when switching between the open and closed states, thereby increasing mutual friction loss, which would increase the resistance received by the first car door and the second car door during movement and increase the loss of elevator operation.

[0046] Specifically, the landing door lock roller assembly 3 can be composed of a first-layer lock roller 31 and a second-layer lock roller 32. During the switching process between the open and closed states of the car door lock device, the clamping door knife 21 abuts against the first-layer lock roller 31, and the unlocking door knife 24 abuts against the second-layer lock roller 32, so that the clamping door knife 21 and the unlocking door knife 24 can jointly clamp the landing door lock roller assembly 3, thereby preventing the car door and the landing door from moving around.

[0047] It should be noted that the aforementioned car door lock device, by setting a clamping wheel door knife 21 and an unlocking door knife 24 on the base 2 and setting a lifting knife assembly on the top of the door operator frame 1, allows the clamping wheel door knife 21 and the unlocking door knife 24 to jointly clamp the landing door lock roller assembly 3 during the switching between the open and closed states of the car door lock device. This maintains a fixed relative position between the car door and the landing door, preventing them from moving around during the switching between the open and closed states, thus avoiding situations where the landing door cannot be closed, which could endanger the safety of passengers inside the elevator. The accident; and because the baffle plate 13 is detachably installed, when the landing door is obstructed from closing and the clamping wheel door knife 21 needs to apply closing force to the landing door lock roller assembly, the baffle plate 13 can restrict the lifting of the clamping wheel door knife 21 by pressing against the baffle wheel 212, preventing the car door and landing door from moving against each other and reducing safety risks; and because the baffle plate 13 is detachable, the position and structure of the baffle plate 13 can be set according to different landing door device sizes and structures, thereby improving design efficiency, reducing response time, and making it more suitable for promotion and application in the renovation of old elevators.

[0048] In some embodiments, such as Figure 1 As shown, the door machine frame 1 has multiple spaced mounting holes, and the blocking plate 13 has a connecting hole. A threaded connector 4 passes through the connecting hole and can be threaded into any mounting hole. This allows the blocking plate 13 to be installed at different positions on the door machine frame 1 through the mounting holes at different positions according to the size and structure of different door lock devices, thereby speeding up the response.

[0049] In some embodiments, see Figure 1 The blocking plate 13 includes a connecting part 131, which is detachably fixed to the door frame 1. The connecting part 131 is provided with a waist-shaped hole 132. The door frame 1 is provided with a mounting hole that aligns with the waist-shaped hole 132. The car door lock device also includes a threaded connector 4, which passes through the waist-shaped hole 132 and can move along the waist-shaped hole 132. The threaded connector 4 is threadedly engaged with the mounting hole. The position of the threaded connector 4 in the waist-shaped hole 132 will change the installation position of the blocking plate 13, thereby adapting to different sizes and structures of door lock devices.

[0050] Specifically, see Figure 8 Two oblong holes 132 are provided at both ends of the connecting part 131. When the width E of the landing door lock roller assembly 3 is larger, the installation height of the blocking plate 13 can be increased by fixing the threaded connector 4 at the lower part inside the oblong hole 132, thereby making the car door lock device compatible with the landing door lock device.

[0051] In some embodiments, see Figure 1The car door lock device also includes a connecting component 23, one end of which is rotatably connected to the base 2, and the other end is rotatably connected to the clamping wheel door knife 21 via a connecting shaft. The blocking wheel 212 is rotatably mounted on the connecting shaft. This configuration simplifies the structure and reduces costs.

[0052] Specifically, the connecting component 23 can be two swing arms, allowing the door unlocking knife 24 to swing left and right within a certain range.

[0053] In some embodiments, see Figure 1 The lifting knife assembly includes a lifting knife groove 12, which is located on the top of the door machine frame 1 and extends upward toward the door machine frame 1. The top of the clamping wheel door knife 21 extends to the top of the door machine frame 1 and is rotatably provided with a lifting knife roller 211. The lifting knife roller 211 can roll and cooperate with the lifting knife groove 12. When the first clamping wheel door knife 21 swings to the right, it drives the lifting knife roller 211 to move to the right until it abuts against the lifting knife groove 12, and rolls upward along the direction in which the lifting knife groove 12 extends, driving the clamping wheel door knife 21 to swing upward.

[0054] In some embodiments, see Figure 1 The lifting groove 12 has an arc-shaped structure, with the center of the arc located on the side where the lifting roller 211 is located. This allows the lifting roller 211 to roll along the arc after it comes into contact with the lifting groove 12, thereby raising the clamping door knife 21 and separating it from the first-layer door lock roller 31.

[0055] In some embodiments, see Figure 1 The car door lock device also includes a car door lock hook 25 and a lock head 111. The unlocking door knife 24 is swayably mounted on the base 2. The car door lock hook 25 is rotatably mounted on the base 2 and is located on the side of the unlocking door knife 24 near the second door hanging plate 11. The lock head 111 is fixed on the door operator frame. The unlocking door knife 24 can drive the car door lock hook 25 to connect with the lock head 111 to lock the car door lock device in the closed state. The unlocking door knife 24 can also drive the car door lock hook 25 to separate from the lock head 111 to release the lock on the car door lock device. Thus, when the car door lock device enters the closed state, it plays the role of fixing the first door hanging plate 10 and the second door hanging plate 11, thereby locking the car door lock device in the closed state.

[0056] See Figure 1 Specifically, in one embodiment, the door unlocking knife 24 is provided with a flange 241, which is located on the side of the door unlocking knife 24 near the door lock hook 25, and the flange 241 abuts and cooperates with the unlocking roller 251.

[0057] Specifically, the door unlocking knife 24 is connected to the base 2 via two swing arms, thereby enabling the door unlocking knife 24 to swing left and right within a certain range.

[0058] In some embodiments, see Figure 1 The door lock hook 25 is rotatably provided with an unlocking roller 251 on the side near the unlocking door knife 24. The unlocking door knife 24 abuts against the unlocking roller 251. When the unlocking door knife 24 swings to the right, it squeezes the unlocking roller 251, causing the door lock hook 25 to lift up and separate from the lock head 111.

[0059] In some embodiments, see Figure 1 The car door lock device includes a first limiting member 26 and a second limiting member 27. The first limiting member 26 and the second limiting member 27 are disposed on the base 2. The first limiting member 26 is located in the gap formed between the unlocking door knife 24 and the clamping wheel door knife 21. The second limiting member 27 is located on the side of the unlocking door knife 24 near the second door hanging plate 11. When the car door lock device is in the closed state, the first limiting member 26 abuts against the unlocking door knife 24, so that there is a gap between the unlocking door knife 24 and the second door lock roller 32. When the car door lock device engages the locking of the closed state, under the premise that the unlocking door knife 24 has already swung to the right to drive the car door lock hook 25 to lift, the second limiting member 27 restricts the unlocking door knife 24 from swinging further to the right.

[0060] An embodiment of the elevator provided in this application specifically includes a car door locking device to prevent the car door and the landing door from moving around each other, thereby ensuring the safety of elevator operation.

[0061] See Figure 9 In some embodiments, in certain special circumstances, it is not necessary to configure the car door lock hook 25, the unlocking roller 251 and the lock head 111. In this case, the first limiting member 26 and the second limiting member 27 and other components can be omitted. The unlocking door knife 24 can be directly fixed on the base 2. At this time, the unlocking door knife 24, which cannot swing, can still play the role of clamping the door lock roller group 3 together with the swingable clamping wheel door knife 21. Other components, including the blocking plate 13 and the blocking wheel 212, can still be used normally.

[0062] See Figure 3-7 In some embodiments, the detailed operating principle of the aforementioned car door lock device is as follows:

[0063] See Figure 3When the car door lock device reaches the closed state, and the first and second car doors are closed: the unlocking door knife 24 swings to the left due to its own weight until it abuts against the first limiting member 261, the flange 241 and the second limiting member 262 have a gap of B, the unlocking roller 251 abuts against the flange 241, the lifting knife roller 211 abuts against the lifting knife groove 12, so that the clamping wheel door knife 21 is raised to a preset height, the second layer door lock roller 32 and the unlocking door knife 24 have a gap of A, the first layer door lock roller 31 and the clamping wheel door knife 21 have a gap of C1, the width of the layer door lock roller group 3 is E1, and the gap between the first layer door lock roller 31 and the second layer door lock roller 32 is D.

[0064] See Figure 4 The first and second car doors move away from each other for a certain distance until the unlocking door knife 24 just contacts the second door lock roller 32: the gap between the second door lock roller 32 and the unlocking door knife 24 disappears and they abut against each other. As the clamping door knife 21 moves to the left with the base 2 (fixed on the first door hanging plate 10), it swings down due to its own weight. The lifting knife roller 211 always abuts against the lifting knife groove 12. The gap between the first door lock roller 31 and the clamping door knife 21 becomes C2; the gap between the flange 241 and the second limiting member 262 is B; the width of the layer door lock roller group 3 is E1; and the gap between the first door lock roller 31 and the second door lock roller 32 is D. The above parameters do not change.

[0065] See Figure 5 The first and second car doors continue to move away from each other for a distance until the unlocking door knife 24 drives the car door lock hook 25 to lift. The second layer door lock roller 32 abuts against the unlocking door knife 24, causing the car door lock hook 25 to lift and separate from the lock head 111. The gap between the flange 241 and the second limiting member 262 disappears. As the clamping wheel door knife 21 moves to the left with the base 2 (fixed on the first door hanging plate 10), it swings down due to its own weight. The lifting knife roller 211 always abuts against the lifting knife groove 12. The gap between the first layer door lock roller 31 and the clamping wheel door knife 21 becomes C3. The width of the layer door lock roller group 3 is E1, and the gap between the first layer door lock roller 31 and the second layer door lock roller 32 is D. The above parameters have not changed.

[0066] See Figure 6The first car door and the second car door continue to move away from each other for a distance until the first door lock roller 31 and the second door lock roller 32 come into contact with each other (the door lock hook is lifted): Since the rightward swing of the door unlocking knife 24 has abutted against the second limit member 262, and the base 2 and the door unlocking knife 24 continue to move to the left with the first door hanging plate 10, the door unlocking knife 24 turns around and abuts against the second door lock roller 32, causing the door lock hook to lift up until the first door lock roller 31 and the second door lock roller 32 come into contact; the clamping wheel knife 21 swings down to abut against the first door lock roller 31, the gap between the first door lock roller 31 and the clamping wheel knife 21 disappears, the lifting knife roller 211 moves away from the lifting knife groove 12, and the blocking wheel 212 enters below the blocking plate 13.

[0067] See Figure 7 The first car door and the second car door continue to move away from each other until they reach the open state. During the process of opening and closing the doors, the blocking wheel 212 is blocked by the blocking plate 13, and the clamping wheel door knife 21 cannot return to its upward swing. Therefore, the clamping wheel door knife 21 and the unlocking door knife 24 always cooperate to clamp the landing door lock roller 3, ensuring that the car door and the landing door will not move around each other.

[0068] See Figure 7 The first car door and the second car door move closer to each other until they reach the closed state. When the closing is about to be completed, the blocking wheel 212 disengages from the area covered by the blocking plate 13, and the clamping wheel door knife 21 is lifted by the abutting cooperation between the lifting knife roller 211 and the lifting knife groove 12, and the car door lock device reaches the closed state.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
