Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to an automatic control device and method for reducing the swing amplitude of a cable. Background Art

[0002] The elevator runs in the hoistway, and the traction machine provides driving force to rotate the traction wheel, and the cable hanging on the traction wheel drags the car and the counterweight to make reciprocating relative movements up and down. In the process of dragging the car and the counterweight, the cable is affected by external forces such as driving force and wind pressure, and will produce periodic swings. The frequency and amplitude of the cable swing will change with the change of external force. Therefore, the frequency and amplitude of the cable swing are different in the acceleration and deceleration stage, normal operation stage, and at different operating speeds.

[0003] For example, the authorization announcement number "CN201990350U" discloses a "silencing device for eliminating low-frequency noise in an elevator car", which includes symmetrically arranged clamping plates, a group of resonant plates, a slide groove on the resonant plates, a bolt that can slide in the slide groove, and a counterweight fixed on the bolt. However, in actual applications, the vibration and external factors encountered during the elevator operation will change in real time, resulting in different working conditions. Therefore, the setting of this type of counterweight cannot adapt to different working conditions to reduce the cable swing amplitude, and the adjustment is not flexible enough. Summary of the invention

[0004] In view of the problem that the prior art mentioned in the background technology is unable to adaptively reduce the cable swing amplitude under different working conditions, the present invention provides an automatic control device for reducing the cable swing amplitude, which can adjust the counterweight unit to a suitable position under different working conditions, so that even if the working conditions change, the cable swing amplitude can be kept in a relatively stable correction state, with higher flexibility.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions.

[0006] An automatic control device for reducing the swing amplitude of a cable includes a rope clamping assembly connected to the cable, the rope clamping assembly is connected to an automatic adjustment assembly, the automatic adjustment assembly is provided with a counterweight unit that can move relative to the rope clamping assembly, the automatic adjustment assembly can receive an adjustment instruction to drive the counterweight unit to move to a target position, and the counterweight unit can reduce the swing amplitude of the cable to the greatest extent when it is at the target position. In the existing device, a counterweight is provided on the cable to reduce the amplitude, and during the operation of the elevator, it will face different working conditions at different positions, and the external forces such as driving force and wind pressure it is subjected to are also different. Since the elevator is always in a relatively closed space, the existing technology cannot adjust the counterweight in time, and can only select a suitable counterweight to slow down according to the average working condition of the elevator movement in the building, and cannot make flexible adjustments for different working conditions during operation. In this regard, the present application discloses an automatic control device for reducing the swing amplitude of the cable, by connecting a rope clamp assembly to the cable, wherein the cable includes but is not limited to a steel wire rope and a steel belt, and by setting an automatic adjustment assembly on the rope clamp assembly, the position of the counterweight unit can be adjusted in real time, and the position of the counterweight unit relative to the rope clamp assembly can be changed, so that a position that best suits the current working condition can be selected from all the positions of the counterweight unit, and the position can be adjusted to the position by the automatic adjustment assembly, and the position can minimize the swing amplitude of the cable, and the position is the target position; wherein the setting of the target position in the present application can be determined by a variety of methods such as preset according to the running position of the car or real-time detection and modification, thereby ensuring the flexibility of adjustment. wherein the method according to the running position of the car is to determine the target position when the car moves to different positions through simulation experiments, and the target position is determined by the automatic adjustment assembly linking the car position, and the counterweight unit is driven to move; and the real-time detection and modification is to detect the swing amplitude, environmental conditions and other factors in real time, and then analyze and determine in real time, so the automatic adjustment assembly can include a remote control unit and an analysis device, thereby realizing remote automatic adjustment, and updating data in time. This solves the shortcomings of the prior art that it is impossible to make flexible adjustments in real time and that it is inconvenient to adjust in a confined space, so that the elevator is always in the best vibration reduction state during operation; the counterweight unit includes but is not limited to counterweight blocks, counterweight plates, iron blocks, iron cores and other components, which can directly affect the center of gravity of the entire automatic adjustment component as the relative position changes.

[0007] Preferably, the automatic adjustment component includes a base plate, a counterweight unit is slidably connected to the base plate, the counterweight unit is connected to a driving unit, and the driving unit drives the counterweight unit to move on the base plate. The automatic adjustment component includes a base plate, wherein the base plate is slidably connected to the counterweight unit, thereby realizing stepless position change of the counterweight unit on the base plate, which can improve the accuracy of the adjustment position, wherein the driving unit drives the counterweight unit to move, the driving unit includes but is not limited to motor transmission and hydraulic cylinder transmission, and the transmission mode includes but is not limited to sprocket chain transmission, transmission belt transmission, and gear rack transmission.

[0008] Preferably, the base plate is provided with a rack area, the driving unit includes a driving member, the driving member is connected to the counterweight unit, and the driving member is provided with a driving gear meshing with the rack area. The meshing of the rack area and the driving gear can improve the stability of the transmission, wherein the rack area is preferably symmetrically arranged to ensure uniform and stable transmission.

[0009] Preferably, the cable is connected with a cable detection unit, the rope clamping assembly is provided with a rope clamping detection unit, the cable detection unit and the rope clamping detection unit are connected to a control center, and the control center receives the swing signal transmitted by the cable detection unit and the rope clamping detection unit. The cable detection unit and the rope clamping detection unit can detect the vibration state of the cable and the rope clamping assembly, and transmit the data to the control center, which processes and analyzes the data, thereby controlling the driving member to displace the counterweight unit to a suitable position; the cable detection unit on the cable can also be set on the car.

[0010] Preferably, an automatic control method comprises the following steps: S1, the cable detection unit and the rope clamp detection unit transmit the swing signals detected by each unit to the control center; S2. The control center analyzes and compares the swing signals of the cable detection unit and the rope clamp detection unit. The comparison results include: Termination signal: when the swing is at its best; Adjustment signal: when the swing is not in the optimal state; S3. When the comparison result is a termination signal, the automatic adjustment component maintains the position; when the comparison result is an adjustment signal, the control center outputs an adjustment position instruction to the automatic adjustment component, and the automatic adjustment component controls the counterweight unit to move to the specified position.

[0011] The cable and the rope clamping assembly are respectively provided with a cable detection unit and a rope clamping detection unit to obtain detection data, which represent the swing state of the cable or the rope clamping assembly at this time, and the control center analyzes these data. In actual work, the swing state of the cable and the rope clamping assembly can be detected to analyze whether the current swing of the cable and the rope clamping assembly is in the best state. This data analysis is obtained by comparing the data transmitted by the cable detection unit and the rope clamping assembly detection unit by the control center. In step S2, the control center can obtain analysis data for the current swing situation, and perform different execution steps in step S3 for different analysis results: if the comparison result is that the cable and the rope clamping assembly are in the best state, it means that under this working condition, no matter how to continue to move the position of the counterweight unit, it cannot achieve a better vibration reduction effect than the current state, so the control center does not send a signal to move the counterweight unit, or sends a signal to keep the current position of the counterweight unit unchanged; if it is detected that the cable and the rope clamping assembly are in a non-optimal state at this time, a moving command will be issued to the automatic adjustment component to control the moving counterweight unit to the best position, thereby minimizing the vibration amplitude of the cable.

[0012] This type of adjustment method can achieve real-time analysis and adjustment of different working conditions, ensuring that the counterweight unit can quickly respond to the appropriate position under different working conditions of the elevator, thereby providing the maximum effect of reducing the swing amplitude.

[0013] Preferably, establishing a database; The database includes: Target data: The position of the counterweight unit when the cable is in the optimal swing state under various working conditions; Basic data: Under the same working conditions of the target data, when the counterweight unit is located at different positions, the swing signals detected by the cable detection unit and the rope clamp detection unit; In step S3, the control center finds the corresponding working condition in the basic data according to the received swing signal and the position of the counterweight unit, finds the position of the counterweight unit corresponding to the working condition in the target data, and outputs the position instruction to the automatic adjustment component.

[0014] The data in the database include target data and basic data, wherein the target data is the position of the counterweight unit when the cable is in the optimal swinging state under various working conditions, wherein the position can be one or more; then the basic data needs to be established: under the same working conditions of the target data, when the counterweight unit is located at different positions, the swing signals detected by the cable detection unit and the rope clamp detection unit; the establishment of the basic data requires recording the swinging state of the cable and the swinging state of the rope clamp assembly under different working conditions when the counterweight unit is located at different positions on the substrate, and recording multiple groups of data and storing them in the database, each group of data includes working condition information, counterweight unit position information, cable swinging state, and rope clamp assembly swinging state.

[0015] In actual work, the method is as follows: the control center uses the swing values ​​received from the cable detection unit and the rope clamping unit in the current state and the counterweight unit position information sent back by the current signal transceiver unit. When these three data are known, it can deduce the working condition information at this time, and then match the working condition information with the working condition information in the target data to obtain whether the position information of the counterweight unit under the working condition in the target data is consistent with the counterweight unit position information currently received. If the position information is consistent, the control center obtains a termination signal; if the position information is inconsistent, the control center obtains an adjustment signal and sends the counterweight unit position information in the target data to the automatic adjustment component at the same time. The automatic adjustment component then controls the drive to move the counterweight unit to the command position.

[0016] By establishing a database, when the control center receives the swing signal data, it can directly deduce the current working conditions, and then determine the optimal position of the counterweight unit based on previous experimental data and output it to the automatic adjustment component, thereby achieving rapid response while ensuring the accuracy of the position.

[0017] Preferably, in step S3, the automatic adjustment component adopts stepless adjustment to drive the counterweight unit to adjust the position steplessly; during this process, the cable detection unit and the rope clamp detection unit collect the swing signal in real time and send it to the control center for comparison. When the comparison result of the control center is a termination signal, the automatic adjustment component terminates the adjustment.

[0018] When the control center issues a movement command, the automatic adjustment component begins to control the counterweight unit to move through the drive. A stepless movement method is adopted during the movement. It does not move directly to a position specified by the control center, but continuously tries whether the position is the best position during the movement. Therefore, during the stepless movement, the cable detection unit and the rope clamp detection unit will collect feedback data to the control center in real time. The control center determines whether it is in the best state by comparing the swing signal frequency of the cable detection unit and the rope clamp detection unit in real time. If the comparison is the best state, the control center outputs a stop movement signal, and the automatic adjustment component stops the displacement of the counterweight unit through the drive.

[0019] Through stepless adjustment, the position of the counterweight unit can be guaranteed to be in line with the current working conditions. At the same time, after long-term operation, the accuracy of the position can still be guaranteed according to stepless adjustment when the external environmental conditions change, thereby minimizing inaccurate position instructions caused by factors such as equipment wear and environmental changes.

[0020] Preferably, the control center is provided with a collection module; The acquisition module records the comparison data; Comparison data: swing signal value and the starting and final positions of the counterweight unit; The control center receives the input data; Input data: swing signal value and counterweight unit position information; The control center compares the input data with the comparison data. If the input data all corresponds, the control center outputs the final position in the comparison data to the automatic adjustment component.

[0021] When the detection result is an adjustment signal, the position information of the counterweight unit needs to be adjusted. Therefore, the counterweight unit has a starting position and a final position in the process of being converted into a termination signal under the adjustment signal. Therefore, each time the adjustment signal is adjusted to a termination signal in any way, the starting position and the final position of the counterweight unit are recorded through the acquisition module, and the swing signal values ​​of the cable and the rope clamp assembly initially received during the adjustment process are also recorded together. The swing signal values ​​of the cable and the rope clamp assembly initially received and the starting position of the counterweight unit are the initial values ​​received by the control center, and are also the three values ​​corresponding to the adjustment signal.

[0022] After receiving the new input data, the control center will compare the input data with the comparison data. If the cable swing signal data, the rope clamp assembly swing signal data, and the counterweight unit position information correspond to the cable swing signal data, the rope clamp assembly swing signal data, and the counterweight unit position information in a certain group of data in the comparison data, it means that the current state of the cable has been encountered before and has been recorded by the acquisition module. At this time, the control center directly transmits the final position in the group of comparison data to the signal transceiver unit. This setting method can not only ensure the rapid response of the equipment, but also realize the continuous updating and iteration of data, thereby ensuring the accuracy of the final position in the comparison data.

[0023] Preferably, if the input data does not correspond to the comparison data, the control center adopts stepless adjustment, and receives the input data and comparison data in real time during the adjustment process. If all the input data correspond to the comparison data during this process, the control center directly outputs the final position signal and updates the comparison data of the acquisition module.

[0024] When the input data does not correspond to the comparison data, the control center uses stepless adjustment. If the control center has not detected that the cable and rope clamp components are in the best state during the stepless adjustment process, the input data corresponds to the comparison data, which means that this working condition has been encountered before. Therefore, the initial input data is updated to the comparison data, thereby realizing the function of continuous updating and improvement. At the same time, with the continuous use of the elevator, this method can also ensure real-time update of data with higher accuracy.

[0025] Preferably, in step S2, the control center compares the swing signal frequencies of the cable detection unit and the rope clamp detection unit; if the frequencies are the same, it is in a termination signal; if the frequencies are different, it is in an adjustment signal. In actual work, the swing state of the cable and the rope clamp assembly can be detected to analyze whether the current swing of the cable and the rope clamp assembly is in the best state. The general comparison method is to compare the frequency and peak and valley positions of the two states. If it is analyzed that the cable vibration frequency is consistent with the vibration frequency of the present invention, and the peak and valley positions of the two correspond up and down, the peaks and valleys can offset each other at this time, thereby reducing the amplitude. At this time, the swing state of the cable and the rope clamp assembly is the best state; and in the actual application process, in one of the working conditions, if the counterweight unit cannot achieve the situation where the peak and valley positions are completely aligned up and down in the entire motion path on the substrate, then the swing state of the cable and the rope clamp assembly is the best state when the peak and valley are in the closest position in the entire motion path. At this time, it is in the position in the entire motion path where the amplitude reduction effect is most obvious. On the contrary, if it is analyzed that the vibration frequency of the cable and the vibration frequency of the rope clamping assembly are inconsistent, or are not in the above two optimal states, then it is in a non-optimal state.

[0026] The beneficial effects of the present invention are as follows: (1) The counterweight unit can be adjusted to a suitable position under different working conditions, so that the swing amplitude of the cable can be kept in a relatively stable correction state even if the working conditions change, which is more flexible; (2) It can realize real-time analysis and adjustment for different working conditions, ensuring that the counterweight unit can quickly respond to the appropriate position under different working conditions, thereby providing the maximum effect of reducing the swing amplitude; (3) By establishing a database, when the control center receives the swing signal data, it can directly deduce the current working condition, and then obtain the optimal position of the counterweight unit based on the previous experimental data, and output it to the automatic adjustment component, so as to achieve rapid response while ensuring the accuracy of the position; (4) It can ensure the rapid response of the equipment and realize the continuous updating and iteration of data, thereby ensuring the accuracy of the final position in the comparison data.

[0035] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] Embodiment 1: like Figure 1 , 2 As shown in Figures 3 and 4, the assembly and working process of the automatic control device for reducing the swing amplitude of cables in this embodiment are as follows: In this embodiment, a plurality of cables 1 are provided, and a rope clamping assembly 2 is connected to the cables 1, wherein the rope clamping assembly 2 in this embodiment is a block structure, and the rope clamping assembly 2 uniformly clamps the cables 1, and a hole is provided on the rope clamping assembly 2 for the cables 1 to pass through. Further, in this embodiment, the rope clamping assembly 2 includes a vibration-damping intermediate body 22 and a vibration-damping side block 23, wherein the vibration-damping intermediate body 22 is provided in the middle position, and two vibration-damping side blocks 23 are provided, which are respectively located on the two sides of the vibration-damping intermediate body 22, wherein the vibration-damping intermediate body 22 and the vibration-damping side blocks 23 are both provided with groove structures, and the groove structures on the vibration-damping side blocks 23 and the vibration-damping intermediate body 22 are arranged opposite to each other, and the two groove structures are aligned to form a hole through which the cables 1 can pass. At the same time, connecting holes are provided on the vibration-damping intermediate body 22 and the vibration-damping side block 23. The vibration-damping intermediate body 22 and the vibration-damping side block 23 are connected by a rope clamping connector 24. The rope clamping connector 24 in this embodiment is a bolt and screw structure. While connecting and fixing the vibration-damping intermediate body 22 and the vibration-damping side block 23, the vibration-damping side block 23 and the vibration-damping intermediate body 22 can also generate an extrusion force on the cable 1 clamped in the middle, thereby fixing the rope clamping assembly 2 on the cable 1.

[0037] In this embodiment, automatic adjustment components 3 are arranged on both sides of the rope clamping component 2, wherein the automatic adjustment component includes a base plate 32, wherein a mounting plate is arranged at the end of the base plate 32 close to the rope clamping component 2, and the mounting plate is fixedly connected to the rope clamping component 2 through a rope clamping connector 24, and a slide groove is arranged on the base plate 32, and a counterweight unit 31 is slidably connected to the slide groove, and the counterweight unit 31 is connected to a driving unit 33, and the counterweight unit is driven to move by the driving unit, wherein the slide groove is a dovetail groove structure in this embodiment, and rack areas 34 are arranged on both sides of the slide groove of the base plate 32, and the extension square of the rack area 34 is the same as the extension direction of the base plate 32. The counterweight unit 31 slidably connected on the slide groove includes a sliding block 38, wherein the shape of the sliding block 38 is adapted to the shape of the slide groove, and a driving member 35 and a counterweight unit 31 are fixed on the sliding block 38, wherein the driving member 35 is a motor in this embodiment, and a driving gear 36 is arranged on the output port on both sides of the motor, wherein the driving gear 36 is meshed and connected with the rack area 34 on both sides of the base plate 32, and during the operation of the motor, the driving gear 36 rotates to drive the sliding plate to move along the slide groove, thereby changing the position of the counterweight unit 31 on the base plate 32, thereby affecting the vibration reduction effect of the cable 1 under different working conditions. The counterweight unit 31 includes a plurality of stacked counterweight plates 311, and a counterweight fixing member 312 is connected to the counterweight plate 311, and the matching fixing member is a bolt and screw structure. The counterweight unit 31 is arranged on the side of the driving member 35 close to the rope clamping assembly 2, and a limiting rod 321 is respectively arranged at both ends of the base plate 32, wherein the limiting rod 321 can form a limiting constraint effect on the movement of the sliding block 38.

[0038] During operation, the car moves through the connecting cable 1, and the cable 1 is driven by a driving motor fixed on the top of the shaft. During the rotation of the driving motor, it not only drives the cable 1 to move, but also transmits vibration to the cable 1, causing the cable 1 to swing. Since the car moves up and down in the shaft below the driving motor, the vibration transmission direction is from top to bottom. At the same time, due to the characteristics of vibration transmission, the closer the cable 1 is to the car, the greater the swing amplitude is, thereby affecting the operation stability of the car. In this embodiment, the rope clamping assembly 2 is arranged on the cable 1. When the vibration is transmitted from top to bottom, when it passes through the position of the rope clamping assembly 2, the vibration is reduced, thereby ensuring the stability of the car; at the same time, the rope clamping assembly 2 can further reduce the swing amplitude of the cable 1 itself, thereby ensuring the stability of the operation. A cable detection unit is provided on the cable 1, and a rope clamping detection unit 21 is provided on the rope clamping assembly 2, which respectively detect the swinging state of the cable 1 and the rope clamping assembly 2, and send the data to the control center for analysis, and then control the automatic adjustment assembly 3 to adjust the position of the counterweight unit 31 on the clamping plate, and a signal transceiver unit 37 is provided on the driving member 35, which is used to receive the signal from the control center and feedback the current position information of the counterweight unit 31. In order to ensure the best vibration reduction effect during operation, the counterweight unit 31 can move individually or synchronously according to the analysis structure of the control center, that is, the driving members 35 on the substrate 32 on both sides of the rope clamping assembly 2 can adjust the position synchronously or separately; the specific detection principle is: a sensor is installed on the cable (or in the car), and a sensor is also installed on the rope clamping assembly, and these two sensors transmit the collected information to the accelerometer through Bluetooth or remote infrared, and the accelerometer transmits the detected cable vibration frequency and the vibration frequency of the rope clamping assembly to the control center for comparison.

[0039] Embodiment 2: Different from the first embodiment, the driving member 35 in the present embodiment is not driven by a motor to drive the driving gear 36 to engage the rack area 34, but is driven by a hydraulic cylinder and a threaded screw. The rest of the structure is the same as that in the first embodiment.

[0040] Embodiment 3: Different from Example 1, the slide groove in this embodiment does not adopt a dovetail groove structure, but is connected through a C-shaped groove structure. The shape of the relative sliding block 38 connected to the slide groove also changes adaptively, and the remaining structure is the same as in Example 1.

[0041] Embodiment 4: Different from the first embodiment, the present embodiment does not adopt the transmission mode of the rack area 34 meshing with the driving gear 36, but uses a sprocket chain, a conveyor belt or the like to drive the sliding block 38 to move, and the rest of the structure is the same as that in the first embodiment.

[0042] Embodiment 5: What is different from Example 1 is that in this embodiment, automatic adjustment components 3 are connected to the four sides of the rope clamping component 2, that is, the front, back, left and right sides of the rope clamping component 2 are connected to the base plate 32, so that the connection state of the rope clamping component 2 on the cable 1 is more balanced, and the degree of adjustment is more flexible. The two relative groups of automatic adjustment components 3 can be matched and combined in a variety of ways, for example, two relative groups of automatic adjustment components 3 move synchronously, or one group of relative automatic adjustment components 3 moves close to the rope clamping component 2, and the other group of automatic adjustment components 3 moves away from one side of the rope clamping component 2, thereby improving the flexibility of adjustment.

[0043] Embodiment 6: like Figure 4 As shown, this embodiment discloses an automatic control method, including the following steps: S1, the cable detection unit and the rope clamp detection unit 21 transmit the swing signals detected by each to the control center; S2. The control center analyzes and compares the swing signals of the cable detection unit and the rope clamp detection unit 21. The comparison results include: Termination signal: when the swing is at its best; Adjustment signal: when the swing is not in the optimal state; S3. When the comparison result is a termination signal, the automatic adjustment component 3 maintains the position; when the comparison result is an adjustment signal, the control center outputs an adjustment position instruction to the automatic adjustment component 3, and the automatic adjustment component 3 controls the counterweight unit 31 to move to the specified position.

[0044] Specifically, in this embodiment, a cable detection unit and a rope clamping detection unit 21 are respectively provided on the cable 1 and the rope clamping assembly 2, wherein the cable detection unit and the rope clamping detection unit 21 can detect the swing amplitude, frequency, direction and other states of the cable 1 and the rope clamping assembly 2 to obtain detection data, which represents the swing state of the cable 1 or the rope clamping assembly 2 at this time, and sends the data to the control center, which analyzes the data. Connecting the rope clamping assembly 2 to the cable 1 and arranging a counterweight unit 31 connected to the rope clamping assembly 2 can increase the stability of the cable 1, and the relative position of the counterweight unit 31 with respect to the rope clamping assembly 2 will affect the stability provided by the rope clamping assembly 2 to the cable 1. When the cable 1 is in different working conditions, that is, when the cable 1 swings in different states, the optimal position of the counterweight unit 31 on the automatic adjustment assembly 3 also changes relatively. Whether the position is the optimal position is defined based on whether the current position of the counterweight unit 31 can provide the best stability for the cable 1. When in the optimal position, the swing state of the cable 1 and the rope clamping assembly 2 reaches an ideal optimal state. Under the same working condition, the optimal position of the counterweight unit 31 can be one or more.

[0045] In actual work, the swinging state of the cable 1 and the rope clamping assembly 2 can be detected to analyze whether the current swinging of the cable 1 and the rope clamping assembly 2 is in the best state. The general comparison method is to compare the frequencies of the two states. If the vibration frequency of the cable 1 is analyzed to be consistent with the vibration frequency of the present invention, it is in the best state. On the contrary, if the vibration frequency of the cable 1 is analyzed to be inconsistent with the vibration frequency of the present invention, it is in a non-optimal state. This data analysis is obtained by comparing the data transmitted by the cable detection unit and the rope clamping assembly 2 detection unit by the control center. Therefore, in this embodiment, in step S2, the control center can obtain analysis data for the current swing situation, and perform different execution steps in step S3 according to different analysis results: if the comparison result shows that the cable 1 and the rope clamping assembly 2 are in the optimal state, it means that under this working condition, no matter how the position of the counterweight unit 31 continues to be moved, it cannot achieve a better vibration reduction effect than the current state. Therefore, the control center does not send a signal to move the counterweight unit 31, or sends a signal to keep the current position of the counterweight unit 31 unchanged; and if it is detected that the cable 1 and the rope clamping assembly 2 are in a non-optimal state at this time, a movement command will be issued to the automatic adjustment assembly 3 to control the movement of the counterweight unit 31 to the optimal position, thereby minimizing the vibration amplitude of the cable 1.

[0046] The specific setting mode of the automatic control device for reducing the cable swing amplitude used in this embodiment is as follows: a plurality of cables 1 are provided, and a rope clamping assembly 2 is connected to the cables 1, wherein the rope clamping assembly 2 in this embodiment is a block structure, the rope clamping assembly 2 uniformly clamps the cables 1, and a hole is provided on the rope clamping assembly 2 for the cables 1 to pass through. Further, in this embodiment, the rope clamping assembly 2 includes a vibration-damping intermediate body 22 and a vibration-damping side block 23, wherein the vibration-damping intermediate body 22 is provided in the middle position, and two vibration-damping side blocks 23 are provided, which are respectively located on the two sides of the vibration-damping intermediate body 22, wherein the vibration-damping intermediate body 22 and the vibration-damping side blocks 23 are both provided with groove structures, and the groove structures on the vibration-damping side blocks 23 and the vibration-damping intermediate body 22 are arranged opposite to each other, and the two groove structures are aligned to form a hole through which the cables 1 can pass. At the same time, connecting holes are provided on the vibration-damping intermediate body 22 and the vibration-damping side block 23. The vibration-damping intermediate body 22 and the vibration-damping side block 23 are connected by a rope clamping connector 24.

Establish a database, which includes: Target data: the position of the counterweight unit 31 when the cable 1 is in the optimal swing state under various working conditions; Basic data: under the same working condition of the target data, when the counterweight unit 31 is located at different positions, the swing signals detected by the cable detection unit and the rope clamp detection unit 21; S2, the cable detection unit and the rope clamp detection unit 21 transmit the swing signals detected by each to the control center; S3, the control center analyzes and compares the swing signals of the cable detection unit and the rope clamp detection unit 21, and the comparison results include: Termination signal: when the swing is at its best; Adjustment signal: when the swing is not in the optimal state; S4, when the comparison result is a termination signal, the automatic adjustment component 3 is maintained at this position; When the comparison result is an adjustment signal, the control center finds the corresponding working condition in the basic data according to the received swing signal and the position of the counterweight unit 31, finds the position of the counterweight unit 31 corresponding to the working condition in the target data, and outputs the position instruction to the automatic adjustment component 3.

[0049] In this embodiment, a cable detection unit and a rope clamping detection unit 21 are respectively provided on the cable 1 and the rope clamping assembly 2, wherein the cable detection unit and the rope clamping detection unit 21 can detect the swing amplitude, frequency, direction and other states of the cable 1 and the rope clamping assembly 2 to obtain detection data, which represents the swing state of the cable 1 or the rope clamping assembly 2 at this time, and sends the data to the control center, which analyzes the data. Connecting the rope clamping assembly 2 to the cable 1 and arranging a counterweight unit 31 connected to the rope clamping assembly 2 can increase the stability of the cable 1, and the relative position of the counterweight unit 31 with respect to the rope clamping assembly 2 will affect the stability provided by the rope clamping assembly 2 to the cable 1. When the cable 1 is in different working conditions, that is, when the cable 1 swings in different states, the optimal position of the counterweight unit 31 on the automatic adjustment assembly 3 also changes relatively. Whether the position is the optimal position is defined based on whether the current position of the counterweight unit 31 can provide the best stability for the cable 1. When in the optimal position, the swing state of the cable 1 and the rope clamping assembly 2 reaches an ideal optimal state. Under the same working condition, the optimal position of the counterweight unit 31 can be one or more.

[0050] Specifically, it is first necessary to establish a database. The establishment of the database can be carried out on a test machine, or it can be collected in real time from various actual application elevators. The data in the database includes target data and basic data, wherein the target data is the position of the counterweight unit 31 when the cable 1 is in the optimal swinging state under various working conditions; for example, a working condition is selected, and the driving force, wind pressure and other external factors are controlled to be the same, a rope clamping assembly 2 is added to the cable 1, and the counterweight unit 31 is moved along the base plate 32. During this process, the vibration state of the cable 1 is recorded in real time, and the position of the counterweight unit 31 on the base plate 32 corresponding to a node with the smallest vibration amplitude in the process is selected, and this position is the counterweight unit when the cable 1 is in the optimal swinging state under this working condition. 31 position, where the position can be one or more; then it is necessary to establish basic data: under the same working condition of the target data, when the counterweight unit 31 is located at different positions, the swing signal detected by the cable detection unit and the rope clamping detection unit 21; the establishment of basic data requires recording the swing state of the cable 1 and the swing state of the rope clamping assembly 2 under different working conditions when the counterweight unit 31 is located at different positions on the substrate 32, wherein whenever the working condition or the position of the counterweight unit 31 changes, the corresponding swing state of the cable 1 and the swing state of the rope clamping unit will change, and multiple groups of data are recorded and stored in the database, each group of data includes working condition information, counterweight unit 31 position information, cable 1 swing state, and rope clamping assembly 2 swing state.

[0051] In actual work, the swing state of the cable 1 and the rope clamping assembly 2 can be detected to analyze whether the current swing of the cable 1 and the rope clamping assembly 2 is in the optimal state. The comparison method in this embodiment is that the control center uses the swing values ​​received from the cable detection unit and the rope clamping unit in the current state and the position information of the counterweight unit 31 currently transmitted back by the signal transceiver unit 37. When the three data are known, the working condition information at this time can be deduced, and then the working condition information is matched with the working condition information in the target data to obtain whether the position information of the counterweight unit 31 under the working condition in the target data is consistent with the currently received position information of the counterweight unit 31. If the position information is consistent, the control center obtains a termination signal. If the position information is inconsistent, the control center obtains an adjustment signal and sends the position information of the counterweight unit 31 in the target data to the automatic adjustment assembly 3. Then the automatic adjustment assembly 3 controls the driving member 35 to move the counterweight unit 31 to the command position.

Further, in this embodiment, the rope clamping assembly 2 includes a vibration-damping intermediate body 22 and a vibration-damping side block 23, wherein the vibration-damping intermediate body 22 is provided in the middle position, and two vibration-damping side blocks 23 are provided, which are respectively located on the two sides of the vibration-damping intermediate body 22, wherein the vibration-damping intermediate body 22 and the vibration-damping side blocks 23 are both provided with groove structures, and the groove structures on the vibration-damping side blocks 23 and the vibration-damping intermediate body 22 are arranged opposite to each other, and the two groove structures are aligned to form a hole through which the cables 1 can pass. At the same time, connecting holes are provided on the vibration-damping intermediate body 22 and the vibration-damping side block 23. The vibration-damping intermediate body 22 and the vibration-damping side block 23 are connected by a rope clamping connector 24. The rope clamping connector 24 in this embodiment is a bolt and screw structure. While connecting and fixing the vibration-damping intermediate body 22 and the vibration-damping side block 23, the vibration-damping side block 23 and the vibration-damping intermediate body 22 can also generate an extrusion force on the cable 1 clamped in the middle, thereby fixing the rope clamping assembly 2 on the cable 1.

[0053] In this embodiment, automatic adjustment components 3 are arranged on both sides of the rope clamping component 2, wherein the automatic adjustment component includes a base plate 32, wherein a mounting plate is arranged at the end of the base plate 32 close to the rope clamping component 2, and the mounting plate is fixedly connected to the rope clamping component 2 through a rope clamping connector 24, and a slide groove is arranged on the base plate 32, and a counterweight unit 31 is slidably connected to the slide groove, wherein the slide groove is a dovetail groove structure in this embodiment, and rack areas 34 are arranged on both sides of the slide groove of the base plate 32, and the extension square of the rack area 34 is the same as the extension direction of the base plate 32. The counterweight unit 31 slidably connected on the slide groove includes a sliding block 38, wherein the shape of the sliding block 38 is adapted to the shape of the slide groove, and a driving member 35 and a counterweight unit 31 are fixed on the sliding block 38, wherein the driving member 35 is a motor in this embodiment, and a driving gear 36 is arranged on the output port on both sides of the motor, wherein the driving gear 36 is meshed and connected with the rack area 34 on both sides of the base plate 32, and during the operation of the motor, the driving gear 36 rotates to drive the sliding plate to move along the slide groove, thereby changing the position of the counterweight unit 31 on the base plate 32, thereby affecting the vibration reduction effect of the cable 1 under different working conditions. The counterweight unit 31 includes a plurality of stacked counterweight plates 311, and a counterweight fixing member 312 is connected to the counterweight plate 311, and the matching fixing member is a bolt and screw structure. The counterweight unit 31 is arranged on the side of the driving member 35 close to the rope clamping assembly 2, and a limiting rod 321 is respectively arranged at both ends of the base plate 32, wherein the limiting rod 321 can form a limiting constraint effect on the movement of the sliding block 38.

[0054] Embodiment 8: like Figure 6 As shown, this embodiment discloses an automatic control method, including the following steps: S1, the cable detection unit and the rope clamp detection unit 21 transmit the swing signals detected by each to the control center; S2. The control center analyzes and compares the swing signals of the cable detection unit and the rope clamp detection unit 21. The comparison results include: Termination signal: when the swing is at its best; Adjustment signal: when the swing is not in the optimal state; S3. When the comparison result is a termination signal, the automatic adjustment component 3 maintains this position; when the comparison result is an adjustment signal, the automatic adjustment component 3 adopts stepless adjustment to drive the counterweight unit 31 to steplessly adjust the position; during this process, the cable detection unit and the rope clamp detection unit 21 collect the swing signal in real time and send it to the control center for comparison. When the comparison result of the control center is a termination signal, the automatic adjustment component 3 terminates the adjustment.

[0055] Specifically, in this embodiment, a cable detection unit and a rope clamping detection unit 21 are respectively provided on the cable 1 and the rope clamping assembly 2, wherein the cable detection unit and the rope clamping detection unit 21 can detect the swing amplitude, frequency, direction and other states of the cable 1 and the rope clamping assembly 2 to obtain detection data, which represents the swing state of the cable 1 or the rope clamping assembly 2 at this time, and sends the data to the control center, which analyzes the data. Connecting the rope clamping assembly 2 to the cable 1 and arranging a counterweight unit 31 connected to the rope clamping assembly 2 can increase the stability of the cable 1, and the relative position of the counterweight unit 31 with respect to the rope clamping assembly 2 will affect the stability provided by the rope clamping assembly 2 to the cable 1. When the cable 1 is in different working conditions, that is, when the cable 1 swings in different states, the optimal position of the counterweight unit 31 on the automatic adjustment assembly 3 also changes relatively. Whether the position is the optimal position is defined based on whether the current position of the counterweight unit 31 can provide the best stability for the cable 1. When in the optimal position, the swing state of the cable 1 and the rope clamping assembly 2 reaches an ideal optimal state. Under the same working condition, the optimal position of the counterweight unit 31 can be one or more.

[0056] In actual work, the swinging state of the cable 1 and the rope clamping assembly 2 can be detected to analyze whether the current swinging of the cable 1 and the rope clamping assembly 2 is in the best state. The general comparison method is to compare the frequencies of the two states. If the vibration frequency of the cable 1 is analyzed to be consistent with the vibration frequency of the present invention, it is in the best state. On the contrary, if the vibration frequency of the cable 1 is analyzed to be inconsistent with the vibration frequency of the present invention, it is in a non-optimal state. This data analysis is obtained by comparing the data transmitted by the cable detection unit and the rope clamping assembly 2 detection unit by the control center. Therefore, in this embodiment, in step S2, the control center can obtain analysis data for the current swing situation, and perform different execution steps in step S3 according to different analysis results: if the comparison result shows that the cable 1 and the rope clamping assembly 2 are in the optimal state, it means that under this working condition, no matter how the position of the counterweight unit 31 is continued to be moved, it cannot achieve a better vibration reduction effect than the current state. Therefore, the control center does not send a signal to move the counterweight unit 31, or sends a signal to keep the current position of the counterweight unit 31 unchanged; and if it is detected that the cable 1 and the rope clamping assembly 2 are in a non-optimal state at this time, a movement command will be issued to the automatic adjustment assembly 3. In this embodiment, when the control center After the control center issues a movement command, the automatic adjustment component 3 begins to control the counterweight unit 31 to move through the driving member 35, wherein a stepless movement method is adopted during the movement process. Instead of directly moving to a position specified by the control center, it continuously tries whether the position is the best position during the movement process. Therefore, during the stepless movement process, the cable detection unit and the rope clamp detection unit 21 will collect feedback data to the control center in real time. The control center determines whether it is in the best state by comparing the swing signal frequencies of the cable detection unit and the rope clamp detection unit 21 in real time. If the comparison is the best state, the control center outputs a stop movement signal, and the automatic adjustment component 3 stops the displacement of the counterweight unit 31 through the driving member 35.

[0057] The specific setting mode of the automatic control device for reducing the cable swing amplitude used in this embodiment is as follows: a plurality of cables 1 are provided, and a rope clamping assembly 2 is connected to the cables 1, wherein the rope clamping assembly 2 in this embodiment is a block structure, the rope clamping assembly 2 uniformly clamps the cables 1, and a hole is provided on the rope clamping assembly 2 for the cables 1 to pass through. Further, in this embodiment, the rope clamping assembly 2 includes a vibration-damping intermediate body 22 and a vibration-damping side block 23, wherein the vibration-damping intermediate body 22 is provided in the middle position, and two vibration-damping side blocks 23 are provided, which are respectively located on the two sides of the vibration-damping intermediate body 22, wherein the vibration-damping intermediate body 22 and the vibration-damping side blocks 23 are both provided with groove structures, and the groove structures on the vibration-damping side blocks 23 and the vibration-damping intermediate body 22 are arranged opposite to each other, and the two groove structures are aligned to form a hole through which the cables 1 can pass. At the same time, connecting holes are provided on the vibration-damping intermediate body 22 and the vibration-damping side block 23. The vibration-damping intermediate body 22 and the vibration-damping side block 23 are connected by a rope clamping connector 24. The rope clamping connector 24 in this embodiment is a bolt and screw structure. While connecting and fixing the vibration-damping intermediate body 22 and the vibration-damping side block 23, the vibration-damping side block 23 and the vibration-damping intermediate body 22 can also generate an extrusion force on the cable 1 clamped in the middle, thereby fixing the rope clamping assembly 2 on the cable 1.

[0058] In this embodiment, automatic adjustment components 3 are arranged on both sides of the rope clamping component 2, wherein the automatic adjustment component includes a base plate 32, wherein a mounting plate is arranged at the end of the base plate 32 close to the rope clamping component 2, and the mounting plate is fixedly connected to the rope clamping component 2 through a rope clamping connector 24, and a slide groove is arranged on the base plate 32, and a counterweight unit 31 is slidably connected to the slide groove, wherein the slide groove is a dovetail groove structure in this embodiment, and rack areas 34 are arranged on both sides of the slide groove of the base plate 32, and the extension square of the rack area 34 is the same as the extension direction of the base plate 32. The counterweight unit 31 slidably connected on the slide groove includes a sliding block 38, wherein the shape of the sliding block 38 is adapted to the shape of the slide groove, and a driving member 35 and a counterweight unit 31 are fixed on the sliding block 38, wherein the driving member 35 is a motor in this embodiment, and a driving gear 36 is arranged on the output port on both sides of the motor, wherein the driving gear 36 is meshed and connected with the rack area 34 on both sides of the base plate 32, and during the operation of the motor, the driving gear 36 rotates to drive the sliding plate to move along the slide groove, thereby changing the position of the counterweight unit 31 on the base plate 32, thereby affecting the vibration reduction effect of the cable 1 under different working conditions. The counterweight unit 31 includes a plurality of stacked counterweight plates 311, and a counterweight fixing member 312 is connected to the counterweight plate 311, and the matching fixing member is a bolt and screw structure. The counterweight unit 31 is arranged on the side of the driving member 35 close to the rope clamping assembly 2, and a limiting rod 321 is respectively arranged at both ends of the base plate 32, wherein the limiting rod 321 can form a limiting constraint effect on the movement of the sliding block 38.

[0059] Embodiment 9: like Figure 7 As shown, this embodiment discloses an automatic control method, including the following steps: S1, the cable detection unit and the rope clamp detection unit 21 transmit the swing signals detected by each to the control center; S2. The control center analyzes and compares the swing signals of the cable detection unit and the rope clamp detection unit 21. The comparison results include: Termination signal: when the swing is at its best; Adjustment signal: when the swing is not in the optimal state; S3, the control center sets up the acquisition module; The acquisition module records the comparison data; Comparison data: swing signal value and the starting position and final position of the counterweight unit 31; The control center receives the input data; Input data: swing signal value and counterweight unit 31 position information; When the comparison result is a termination signal, the automatic adjustment component 3 is maintained at this position; When the comparison result is an adjustment signal, the control center compares the input data with the comparison data. If the input data all correspond, the control center outputs the final position in the comparison data to the automatic adjustment component 3.

[0060] Specifically, in this embodiment, a cable detection unit and a rope clamping detection unit 21 are respectively provided on the cable 1 and the rope clamping assembly 2, wherein the cable detection unit and the rope clamping detection unit 21 can detect the swing amplitude, frequency, direction and other states of the cable 1 and the rope clamping assembly 2 to obtain detection data, which represents the swing state of the cable 1 or the rope clamping assembly 2 at this time, and sends the data to the control center, which analyzes the data. Connecting the rope clamping assembly 2 to the cable 1 and arranging a counterweight unit 31 connected to the rope clamping assembly 2 can increase the stability of the cable 1, and the relative position of the counterweight unit 31 with respect to the rope clamping assembly 2 will affect the stability provided by the rope clamping assembly 2 to the cable 1. When the cable 1 is in different working conditions, that is, when the cable 1 swings in different states, the optimal position of the counterweight unit 31 on the automatic adjustment assembly 3 also changes relatively. Whether the position is the optimal position is defined based on whether the current position of the counterweight unit 31 can provide the best stability for the cable 1. When in the optimal position, the swing state of the cable 1 and the rope clamping assembly 2 reaches an ideal optimal state. Under the same working condition, the optimal position of the counterweight unit 31 can be one or more.

[0061] In actual work, the swing state of the cable 1 and the rope clamping assembly 2 can be detected to analyze whether the current swing of the cable 1 and the rope clamping assembly 2 is in the best state. In this embodiment, the comparison and adjustment method in Embodiment 7 and Embodiment 8 can be adopted, that is, the judgment and adjustment can be performed by deducing and simulating through the database, or the best position can be continuously tried by comparing the frequency and adopting the stepless adjustment method. Both of these adjustment methods are the position adjustment methods of the counterweight unit 31 when the judgment structure of the control center is in the adjustment signal. Therefore, it can be seen that when the detection result is the adjustment signal, the position information of the counterweight unit 31 needs to be adjusted. Therefore, the counterweight unit 31 has a starting position and a final position in the process of being converted into a termination signal under the adjustment signal. Therefore, no matter how the adjustment signal is adjusted to the termination signal, the starting position and the final position of the counterweight unit 31 are recorded by the acquisition module each time, and the swing signal values ​​of the cable 1 and the rope clamping assembly 2 initially received during the adjustment process are also recorded together, wherein the swing signal values ​​of the cable 1 and the rope clamping assembly 2 initially received and the starting position of the counterweight unit 31 are the initial values ​​received by the control center, and are also the three values ​​corresponding to the adjustment signal.

[0062] Therefore, through the continuous adjustment of Examples 7 and 8, the data recorded in the acquisition module gradually increases, and these data are all situations that the elevator often encounters during operation. Subsequently, after the control center receives new input data, the input data is compared with the comparison data. If the swing signal data of cable 1, the swing signal data of rope clamping assembly 2, and the position information of counterweight unit 31 correspond to the same swing signal data of cable 1, the swing signal data of rope clamping assembly 2, and the position information of counterweight unit 31 in a certain group of data in the comparison data, it means that the state of cable 1 at this time has been encountered before and has been recorded by the acquisition module. At this time, the control center directly transmits the final position in the group of comparison data to the signal transceiver unit 37, thereby avoiding the steps of derivation and stepless trial required in Examples 7 and 8, and obtaining the position information of counterweight unit 31 more quickly.

[0063] If the input data received by the control center cannot match the comparison data, the adjustment method in Example 7 can be directly switched to. If the stepless adjustment method of trying the best position in Example 8 is adopted, the stepless adjustment is continued, and the input data and the comparison data are compared in real time during the stepless adjustment process. In this case, there are also two situations: (1) until the stepless adjustment is performed until the control center detects that the cable 1 and the rope clamp assembly 2 are in the best state, there is no node corresponding to the comparison data in this process. At this time, a new set of comparison data is entered, which means that this working condition has not been encountered before; (2) If during the stepless adjustment process, the control center has not yet detected that the cable 1 and the rope clamp assembly 2 are in the best state, the input data corresponds to the comparison data, which means that this working condition has been encountered before. It is because the counterweight unit 31 is in a different position, resulting in no difference in value and no successful comparison. Therefore, the initial input data is updated to the group of comparison data, which means that when the input data received later is the same as the input data received this time, or the same as the corresponding data in the comparison data, the final position in the group of comparison data can be directly output, thereby realizing the function of continuous updating and improvement. At the same time, with the continuous use of the elevator, this method can also ensure real-time update of data with higher accuracy.

According to an automatic control method as claimed in claim 5, It is characterized in that Establish database; The database includes: Target data: the position of the counterweight unit (31) when the cable (1) is in an optimal swing state under various working conditions; Basic data: swing signals detected by the cable detection unit and the rope clamp detection unit (21) when the counterweight unit (31) is located at different positions under the same working conditions of the target data; In step S3, the control center finds the corresponding working condition in the basic data based on the received swing signal and the position of the counterweight unit (31), finds the position of the counterweight unit (31) corresponding to the working condition in the target data, and outputs the position instruction to the automatic adjustment component (3).

7. According to an automatic control method as claimed in claim 5, It is characterized in that In step S3, the automatic adjustment component (3) uses stepless adjustment to drive the counterweight unit (31) to steplessly adjust its position. During this process, the cable detection unit and the rope clamp detection unit (21) collect swing signals in real time and send them to the control center for comparison. When the comparison result of the control center is a termination signal, the automatic adjustment component (3) terminates the adjustment.

8. An automatic control method according to any one of claims 5 to 7, It is characterized in that The control center sets up the acquisition module; The acquisition module records the comparison data; Comparison data: the swing signal value and the starting position and final position of the counterweight unit (31); The control center receives the input data; Input data: swing signal value and counterweight unit (31) position information; The control center compares the input data with the comparison data. If the input data all corresponds, the control center outputs the final position in the comparison data to the automatic adjustment component (3).

9. An automatic control method according to claim 8, It is characterized in that If the input data does not correspond to the comparison data, the control center adopts stepless adjustment, and receives the input data and comparison data in real time during the adjustment process. If all the input data in this process corresponds to the comparison data, the control center directly outputs the final position signal and updates the comparison data of the acquisition module.

10. An automatic control method according to any one of claims 5 to 7, It is characterized in that In step S2, the control center compares the frequencies of the swing signals of the cable detection unit and the rope clamp detection unit (21); if the frequencies are the same, a termination signal is provided; if the frequencies are different, an adjustment signal is provided.
