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 cable swing amplitude. Background Art

[0002] An elevator operates within a hoistway, driven by a traction machine that rotates a traction sheave. Cables suspended from the traction sheave pull the car and counterweight in reciprocating relative motion. As the cables pull the car and counterweight, they are subjected to external forces such as the driving force and wind pressure, causing them to oscillate periodically. The frequency and amplitude of these oscillations vary with these external forces, resulting in variations during acceleration and deceleration, normal operation, and at different speeds.

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

[0004] In response to the problem mentioned in the background technology that the existing technology cannot 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 cable swing amplitude includes a cable clamp assembly connected to the cable, the cable clamp assembly connected to an automatic adjustment assembly, the automatic adjustment assembly provided with a counterweight unit capable of displacement relative to the cable clamp assembly, the automatic adjustment assembly capable of receiving an adjustment instruction to drive the counterweight unit to a target position, and the counterweight unit being capable of minimizing the cable swing amplitude when in the target position. In existing devices, a counterweight is provided on the cable to reduce the amplitude. However, during operation, an elevator faces different operating conditions at different positions, and is subjected to different external forces such as driving force and wind pressure. Since the elevator is always in a relatively enclosed space, the existing technology cannot adjust the counterweight in a timely manner. Instead, the existing technology can only select an appropriate counterweight to reduce the vibration based on the average operating condition of the elevator movement in the building, and cannot flexibly adjust to different operating conditions during operation.

[0007] To this end, the present application discloses an automatic control device for reducing cable swing amplitude. The device comprises a cable clamp assembly connected to the cable, including but not limited to a steel wire rope or steel belt, and an automatic adjustment assembly disposed on the clamp assembly. This device adjusts the position of the counterweight unit in real time, changing the relative position of the counterweight unit to the clamp assembly. This allows the device to select a position from among all the counterweight unit positions that best suits the current operating conditions. The automatic adjustment assembly adjusts the position to the position that minimizes the cable swing amplitude, which is referred to as the target position. The target position can be determined by various methods, such as presetting the position of the elevator car or by real-time detection and modification, thereby ensuring flexibility in adjustment. The method of determining the target position based on the elevator car's operating position involves determining the target position when the elevator car moves to different positions through simulation experiments. The automatic adjustment assembly then determines the target position by linking the elevator car position and driving the counterweight unit to move. The real-time detection and modification involves real-time detection of factors such as swing amplitude and environmental conditions, followed by real-time analysis and determination. Therefore, the automatic adjustment assembly can include a remote control unit and an analysis device, enabling remote automated adjustment and timely data updates. This solves the shortcomings of the existing technology that it cannot be flexibly adjusted in real time and 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.

[0008] Preferably, the automatic adjustment component includes a base plate, a counterweight unit is slidably connected to the base plate, and the counterweight unit is connected to a drive unit, and the drive 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 achieving stepless position change of the counterweight unit on the base plate, which can improve the accuracy of the adjustment position, wherein the drive unit drives the counterweight unit to move, and the drive unit includes but is not limited to motor transmission and hydraulic cylinder transmission, and the transmission method includes but is not limited to sprocket chain transmission, transmission belt transmission, and gear rack transmission.

[0009] Preferably, the base plate is provided with a rack area, the drive unit includes a driving member connected to the counterweight unit, and the driving member is provided with a drive gear that meshes with the rack area. The meshing of the rack area and the drive gear improves transmission stability, and the rack areas are preferably arranged symmetrically to ensure uniform and smooth transmission.

[0010] Preferably, the cable is connected to a cable detection unit, and 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 vibration signals 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 to control the drive member to move the counterweight unit to the appropriate position. The cable detection unit on the cable can also be provided on the car.

[0011] Preferably, an automatic control method comprises the following steps:

[0012] S1, the cable detection unit and the rope clamp detection unit transmit the swing signals detected by each to the control center;

[0013] 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:

[0014] Termination signal: when the swing is at its best;

[0015] Adjustment signal: when the swing is not in the optimal state;

[0016] 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.

[0017] The cable and the rope clamp assembly are respectively equipped with a cable detection unit and a rope clamp detection unit, which generate detection data representing the current swing state of the cable or rope clamp assembly. The control center analyzes this data. In actual operation, the swing state of the cable and rope clamp assembly can be detected to analyze whether the current swing state of the cable and rope clamp assembly is optimal. This data analysis is obtained by the control center comparing the data transmitted by the cable detection unit and the rope clamp assembly detection unit. In step S2, the control center can obtain analysis data on the current swing state and perform different execution steps in step S3 based on different analysis results. If the comparison result shows that the cable and rope clamp assembly are in the optimal state, it means that under this operating condition, no matter how the counterweight unit is moved, it will not achieve a better vibration reduction effect than the current state. Therefore, the control center does not issue a signal to move the counterweight unit, or issues a signal to maintain the current position of the counterweight unit. If it is detected that the cable and rope clamp assembly are not in the optimal state, it will issue a movement command to the automatic adjustment component to control the movement of the counterweight unit to the optimal position, thereby minimizing the vibration amplitude of the cable.

[0018] 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.

[0019] Preferably, a database is established;

[0020] The database includes:

[0021] Target data: The position of the counterweight unit when the cable is in the optimal swing state under various working conditions;

[0022] Basic data: Under the same working conditions as the target data, the swing signals detected by the cable detection unit and the rope clamp detection unit when the counterweight unit is located in different positions;

[0023] 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 counterweight unit position corresponding to the working condition in the target data, and outputs the position instruction to the automatic adjustment component.

[0024] 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 swing state under various working conditions, wherein the position can be one or more; then it is necessary to establish basic data: under the same working conditions of the target data, when the counterweight unit is located at different positions, the swing signal detected by the cable detection unit and the rope clamp detection unit; the establishment of basic data requires recording the swing state of the cable and the swing 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 sets of data and storing them in the database, each set of data includes working condition information, counterweight unit position information, cable swing state, and rope clamp assembly swing state.

[0025] 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 currently received counterweight unit position information. 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.

[0026] By establishing a database, when the control center receives the swing signal data, it can directly deduce the current working conditions. Then, based on the previous experimental data, the optimal position of the counterweight unit can be obtained and output to the automatic adjustment component, thereby achieving rapid response while ensuring the accuracy of the position.

[0027] Preferably, in step S3, the automatic adjustment component adopts stepless adjustment to drive the counterweight unit to adjust its 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.

[0028] When the control center issues a movement command, the automatic adjustment component begins to control the counterweight unit to move through the drive part. The movement process adopts a stepless movement method. It does not move directly to a position specified by the control center, but continuously tries to see if 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 will collect feedback data to the control center in real time. The control center determines whether it is 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 part.

[0029] 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.

[0030] As a preference, the control center is provided with a collection module;

[0031] The acquisition module records the comparison data;

[0032] Comparison data: swing signal value and the starting and final positions of the counterweight unit;

[0033] The control center receives input data;

[0034] Input data: swing signal value and counterweight unit position information;

[0035] 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.

[0036] When the detection result is an adjustment signal, the position information of the counterweight unit needs to be adjusted. Therefore, the counterweight unit will have 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 by any method, the starting position and the final position of the counterweight unit are recorded by the acquisition module. At the same time, 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.

[0037] After receiving the new input data, the control center compares it with the comparison data. If the cable swing signal data, the rope clamp assembly swing signal data, and the counterweight unit position information match those in a certain set of comparison data, it means that the cable state at that 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 comparison data set to the signal transceiver unit. This setting method can ensure the rapid response of the equipment while achieving continuous data updates and iterations, thereby ensuring the accuracy of the final position in the comparison data.

[0038] 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 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.

[0039] If the input data doesn't match the comparison data, the control center uses stepless adjustment. If, during the stepless adjustment process, the control center hasn't yet detected that the cables and rope clamps are in optimal condition, the input data matches the comparison data, indicating that the condition has been encountered before. Therefore, the initial input data is updated to the comparison data, thus achieving continuous updating and improvement. This method also ensures real-time data updates and higher accuracy as the elevator continues to be used.

[0040] 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 optimal state. The general comparison method is to compare the frequencies 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, thereby reducing the amplitude. At this time, the swing state of the cable and the rope clamp assembly is the optimal state; and in actual application, in one working condition, if the counterweight unit cannot achieve the situation where the peak and valley positions are completely aligned in the entire motion path on the substrate, then the swing state of the cable and the rope clamp assembly is the optimal state when the peak and valley are closest 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 is inconsistent with the vibration frequency of the rope clamping assembly, or is not in the above two optimal states, it is in a non-optimal state.

[0041] The beneficial effects of the present invention are as follows:

[0042] (1) The counterweight unit can be adjusted to a suitable position under different working conditions, so that the cable swing amplitude can be kept in a relatively stable correction state even if the working conditions change, which is more flexible;

[0043] (2) It can realize 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, thereby providing the maximum effect of reducing the swing amplitude;

[0044] (3) By establishing a database, the control center can directly deduce the current working condition when receiving the swing signal data. Then, based on the previous experimental data, the optimal position of the counterweight unit is obtained and output to the automatic adjustment component, thereby achieving rapid response while ensuring the accuracy of the position.

[0045] (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. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0058] Example 1:

[0059] like Figure 1 、 2 As shown in Figures 3 and 4, the assembly and operation process of the automatic control device for reducing cable swing amplitude in this embodiment are as follows: In this embodiment, a plurality of cables 1 are provided, and a cable clamping assembly 2 is connected to each cable 1. The cable clamping assembly 2 in this embodiment is a block-shaped structure that uniformly clamps the cables 1 and is provided with holes for the cables 1 to pass through. Furthermore, in this embodiment, the cable clamping assembly 2 includes a vibration-damping intermediate body 22 and a vibration-damping side block 23. The vibration-damping intermediate body 22 is positioned in the middle, and two vibration-damping side blocks 23 are provided, one on each side of the vibration-damping intermediate body 22. The vibration-damping intermediate body 22 and the vibration-damping side blocks 23 are both provided with groove structures. The groove structures on the vibration-damping side blocks 23 and the vibration-damping intermediate body 22 are arranged in a facing relationship. When the two groove structures are aligned, a hole is formed through which the cables 1 can pass. At the same time, connection 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 therein, thereby fixing the rope clamping assembly 2 on the cable 1.

[0060] In this embodiment, automatic adjustment components 3 are provided on both sides of the rope clamping component 2, wherein the automatic adjustment component includes a base plate 32, wherein a mounting plate is provided at the end of the base plate 32 near the rope clamping component 2, and the mounting plate is fixedly connected to the rope clamping component 2 through the rope clamping connector 24, and a slide groove is provided 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 driving unit drives the counterweight unit to move, wherein the slide groove in this embodiment is a dovetail groove structure, and the base plate 32 is provided with rack areas 34 on both sides of the slide groove, 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, which is slidably connected to the chute, includes a sliding block 38, wherein the shape of the sliding block 38 is adapted to the shape of the chute. A driving member 35 and the counterweight unit 31 are fixed to the sliding block 38. In this embodiment, the driving member 35 is a motor. Drive gears 36 are provided on the output ports on both sides of the motor. The drive gears 36 mesh with the rack areas 34 on both sides of the base plate 32. During operation of the motor, the drive gears 36 rotate, thereby driving the sliding plate to move along the chute, 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 the counterweight plates 311 are connected to the counterweight fixing members 312, which are bolt and screw structures. The counterweight unit 31 is arranged on the side of the driving member 35 near the rope clamp assembly 2. Limit rods 321 are provided at both ends of the base plate 32, wherein the limit rods 321 can form a limit constraint effect on the movement of the sliding block 38.

[0061] During operation, the car moves through the connecting cable 1, and the cable 1 is driven by a drive motor fixed to the top of the shaft. During the rotation of the drive 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 drive 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, the vibration is reduced when passing through the position of the rope clamping assembly 2, 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 installed on cable 1, and a rope clamp detection unit 21 is installed on rope clamp assembly 2. These units detect the swinging state of cable 1 and rope clamp assembly 2, respectively, and transmit the data to the control center for analysis. The automatic adjustment assembly 3 then controls the position of the counterweight unit 31 on the clamping plate. A signal transceiver unit 37 is installed on the driver 35 to receive signals from the control center and provide feedback on the current position of the counterweight unit 31. During operation, to ensure optimal vibration reduction, the counterweight unit 31 can move independently or synchronously based on the control center's analysis. Specifically, the driver 35 on the base plate 32 on either side of the rope clamp assembly 2 can adjust its position synchronously or independently. The specific detection principle is as follows: a sensor is installed on the cable (or in the car) and a sensor is installed on the rope clamp assembly. These two sensors transmit the collected information to an accelerometer via Bluetooth or remote infrared. The accelerometer transmits the detected cable vibration frequency and the rope clamp assembly vibration frequency to the control center for comparison.

[0062] Example 2:

[0063] Different from Example 1, the driving member 35 in this 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 Example 1.

[0064] Example 3:

[0065] 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. The rest of the structure is the same as in Example 1.

[0066] Example 4:

[0067] Different from Example 1, this embodiment does not adopt the transmission method of the rack area 34 meshing with the drive gear 36. Instead, a transmission method such as a sprocket chain, a conveyor belt, etc. is used to drive the sliding block 38 to move. The rest of the structure is the same as that in Example 1.

[0068] Example 5:

[0069] 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 various ways, for example, the 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.

[0070] Example 6:

[0071] like Figure 4 As shown, this embodiment discloses an automatic control method, which includes the following steps:

[0072] S1, the cable detection unit and the rope clamp detection unit 21 transmit the swing signals detected by each to the control center;

[0073] 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:

[0074] Termination signal: when the swing is at its best;

[0075] Adjustment signal: when the swing is not in the optimal state;

[0076] 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.

[0077] 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. These data represent the swing state of the cable 1 or the rope clamping assembly 2 at this time, and the data are sent to the control center, which analyzes the data. Connecting the rope clamping assembly 2 to the cable 1 and providing a counterweight unit 31 connected to the rope clamping assembly 2 can increase the stability of the cable 1. 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 current position of the counterweight unit 31 can provide the best stability for the cable 1 is defined as the optimal position. When in the optimal position, the swing state of the cable 1 and the rope clamping assembly 2 reaches the ideal optimal state. Under the same working condition, the optimal position of the counterweight unit 31 can be one or more.

[0078] In actual operation, the swinging state of cable 1 and rope clamp assembly 2 can be detected to analyze whether the current swinging state of cable 1 and rope clamp assembly 2 is optimal. The general comparison method is to compare the frequencies of the two states. If the vibration frequency of cable 1 is analyzed to be consistent with the vibration frequency of the present invention, it is in the optimal state. Otherwise, if the vibration frequency of 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 detection unit of rope clamp assembly 2 in the control center. Therefore, in this embodiment, in step S2, the control center can obtain analysis data on the current swing condition and perform different execution steps in step S3 based on different analysis results: If the comparison result shows that the cable 1 and the rope clamp 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; if it is detected that the cable 1 and the rope clamp assembly 2 are in a non-optimal state at this time, a movement command will be issued to the automatic adjustment component 3 to control the movement of the counterweight unit 31 to the optimal position, thereby minimizing the vibration amplitude of the cable 1.

[0081] Example 7:

[0082] like Figure 5 As shown, this embodiment discloses an automatic control method, which includes the following steps:

[0083] S1. Establish a database, which includes:

[0084] Target data: the position of the counterweight unit 31 when the cable 1 is in the optimal swing state under various working conditions;

[0085] Basic data: under the same working conditions as 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;

[0086] S2, the cable detection unit and the rope clamp detection unit 21 transmit the swing signals detected by each to the control center;

[0087] S3. 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:

[0088] Termination signal: when the swing is at its best;

[0089] Adjustment signal: when the swing is not in the optimal state;

[0090] S4. When the comparison result is a termination signal, the automatic adjustment component 3 is maintained at this position;

[0091] When the comparison result is an adjustment signal, 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.

[0092] 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. These data represent the swing state of the cable 1 or the rope clamping assembly 2 at this time, and the data are sent to the control center, which analyzes the data. Connecting the rope clamping assembly 2 to the cable 1 and providing a counterweight unit 31 connected to the rope clamping assembly 2 can increase the stability of the cable 1. 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 current position of the counterweight unit 31 can provide the best stability for the cable 1 is defined as the optimal position. When in the optimal position, the swing state of the cable 1 and the rope clamping assembly 2 reaches the ideal optimal state. Under the same working condition, the optimal position of the counterweight unit 31 can be one or more.

[0093] Specifically, it is necessary to first establish a database. The establishment of the database can be carried out on a testing 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 swing 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 clamp 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. This position is the counterweight unit when the cable 1 is in the optimal swing state under this working condition. 31 position, where the position can be one or more; then basic data needs to be established: 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 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 base plate 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 including working condition information, counterweight unit 31 position information, cable 1 swing state, and rope clamping assembly 2 swing state.

[0094] In actual operation, 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 these three data are known, the current working condition information can be deduced. Then, the working condition information is matched with the working condition information in the target data to determine 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 generates a termination signal. If the position information is inconsistent, the control center generates 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.

[0095] The specific configuration of the automatic control device for reducing cable swing amplitude used in this embodiment is as follows: a plurality of cables 1 are provided, and a cable clamping assembly 2 is connected to each cable 1. The cable clamping assembly 2 in this embodiment is a block-shaped structure that uniformly clamps the cables 1 and is provided with holes for the cables 1 to pass through. Furthermore, in this embodiment, the cable clamping assembly 2 includes a vibration-damping intermediate body 22 and vibration-damping side blocks 23. The vibration-damping intermediate body 22 is positioned in the middle, and two vibration-damping side blocks 23 are provided, one on each side of the vibration-damping intermediate body 22. Both the vibration-damping intermediate body 22 and the vibration-damping side blocks 23 are provided with groove structures. The groove structures of the vibration-damping side blocks 23 and the vibration-damping intermediate body 22 are arranged in a facing relationship. When the two groove structures are aligned, a hole is formed that can pass through the cable 1. At the same time, connection 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 therein, thereby fixing the rope clamping assembly 2 on the cable 1.

[0096] In this embodiment, automatic adjustment components 3 are provided on both sides of the rope clamping component 2, wherein the automatic adjustment component includes a base plate 32, wherein a mounting plate is provided at the end of the base plate 32 near the rope clamping component 2, and the mounting plate is fixedly connected to the rope clamping component 2 through the rope clamping connector 24, and a slide groove is provided 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 the base plate 32 is provided with a rack area 34 on both sides of the slide groove, 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, which is slidably connected to the chute, includes a sliding block 38, wherein the shape of the sliding block 38 is adapted to the shape of the chute. A driving member 35 and the counterweight unit 31 are fixed to the sliding block 38. In this embodiment, the driving member 35 is a motor. Drive gears 36 are provided on the output ports on both sides of the motor. The drive gears 36 mesh with the rack areas 34 on both sides of the base plate 32. During operation of the motor, the drive gears 36 rotate, thereby driving the sliding plate to move along the chute, 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 the counterweight plates 311 are connected to the counterweight fixing members 312, which are bolt and screw structures. The counterweight unit 31 is arranged on the side of the driving member 35 near the rope clamp assembly 2. Limit rods 321 are provided at both ends of the base plate 32, wherein the limit rods 321 can form a limit constraint effect on the movement of the sliding block 38.

[0097] Example 8:

[0098] like Figure 6 As shown, this embodiment discloses an automatic control method, which includes the following steps:

[0099] S1, the cable detection unit and the rope clamp detection unit 21 transmit the swing signals detected by each to the control center;

[0100] 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:

[0101] Termination signal: when the swing is at its best;

[0102] Adjustment signal: when the swing is not in the optimal state;

[0103] 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 automatic adjustment component 3 adopts stepless adjustment to drive the counterweight unit 31 to adjust the position steplessly; 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.

[0104] 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. These data represent the swing state of the cable 1 or the rope clamping assembly 2 at this time, and the data are sent to the control center, which analyzes the data. Connecting the rope clamping assembly 2 to the cable 1 and providing a counterweight unit 31 connected to the rope clamping assembly 2 can increase the stability of the cable 1. 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 current position of the counterweight unit 31 can provide the best stability for the cable 1 is defined as the optimal position. When in the optimal position, the swing state of the cable 1 and the rope clamping assembly 2 reaches the ideal optimal state. Under the same working condition, the optimal position of the counterweight unit 31 can be one or more.

[0105] In actual operation, the swinging state of cable 1 and rope clamp assembly 2 can be detected to analyze whether the current swinging state of cable 1 and rope clamp assembly 2 is optimal. The general comparison method is to compare the frequencies of the two states. If the vibration frequency of cable 1 is analyzed to be consistent with the vibration frequency of the present invention, it is in the optimal state. Otherwise, if the vibration frequency of 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 detection unit of rope clamp assembly 2 in the control center. Therefore, in this embodiment, in step S2, the control center can obtain analysis data on 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 component 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. The movement process adopts a stepless movement method. It does not move directly to a position specified by the control center, but continuously tries whether the position is the optimal 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 the optimal state by comparing the swing signal frequency of the cable detection unit and the rope clamp detection unit 21 in real time. If the comparison is the optimal 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.

[0106] The specific configuration of the automatic control device for reducing cable swing amplitude used in this embodiment is as follows: a plurality of cables 1 are provided, and a cable clamping assembly 2 is connected to each cable 1. The cable clamping assembly 2 in this embodiment is a block-shaped structure that uniformly clamps the cables 1 and is provided with holes for the cables 1 to pass through. Furthermore, in this embodiment, the cable clamping assembly 2 includes a vibration-damping intermediate body 22 and vibration-damping side blocks 23. The vibration-damping intermediate body 22 is positioned in the middle, and two vibration-damping side blocks 23 are provided, one on each side of the vibration-damping intermediate body 22. Both the vibration-damping intermediate body 22 and the vibration-damping side blocks 23 are provided with groove structures. The groove structures of the vibration-damping side blocks 23 and the vibration-damping intermediate body 22 are arranged in a facing relationship. When the two groove structures are aligned, a hole is formed that can pass through the cable 1. At the same time, connection 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 therein, thereby fixing the rope clamping assembly 2 on the cable 1.

[0107] In this embodiment, automatic adjustment components 3 are provided on both sides of the rope clamping component 2, wherein the automatic adjustment component includes a base plate 32, wherein a mounting plate is provided at the end of the base plate 32 near the rope clamping component 2, and the mounting plate is fixedly connected to the rope clamping component 2 through the rope clamping connector 24, and a slide groove is provided 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 the base plate 32 is provided with a rack area 34 on both sides of the slide groove, 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, which is slidably connected to the chute, includes a sliding block 38, wherein the shape of the sliding block 38 is adapted to the shape of the chute. A driving member 35 and the counterweight unit 31 are fixed to the sliding block 38. In this embodiment, the driving member 35 is a motor. Drive gears 36 are provided on the output ports on both sides of the motor. The drive gears 36 mesh with the rack areas 34 on both sides of the base plate 32. During operation of the motor, the drive gears 36 rotate, thereby driving the sliding plate to move along the chute, 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 the counterweight plates 311 are connected to the counterweight fixing members 312, which are bolt and screw structures. The counterweight unit 31 is arranged on the side of the driving member 35 near the rope clamp assembly 2. Limit rods 321 are provided at both ends of the base plate 32, wherein the limit rods 321 can form a limit constraint effect on the movement of the sliding block 38.

[0108] Example 9:

[0109] like Figure 7 As shown, this embodiment discloses an automatic control method, which includes the following steps:

[0110] S1, the cable detection unit and the rope clamp detection unit 21 transmit the swing signals detected by each to the control center;

[0111] 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:

[0112] Termination signal: when the swing is at its best;

[0113] Adjustment signal: when the swing is not in the optimal state;

[0114] S3, the control center sets up the acquisition module;

[0115] The acquisition module records the comparison data;

[0116] Comparison data: swing signal value and the starting position and final position of the counterweight unit 31;

[0117] The control center receives input data;

[0118] Input data: swing signal value and counterweight unit 31 position information;

[0119] When the comparison result is a termination signal, the automatic adjustment component 3 is maintained at this position;

[0120] 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.

[0121] 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. These data represent the swing state of the cable 1 or the rope clamping assembly 2 at this time, and the data are sent to the control center, which analyzes the data. Connecting the rope clamping assembly 2 to the cable 1 and providing a counterweight unit 31 connected to the rope clamping assembly 2 can increase the stability of the cable 1. 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 current position of the counterweight unit 31 can provide the best stability for the cable 1 is defined as the optimal position. When in the optimal position, the swing state of the cable 1 and the rope clamping assembly 2 reaches the ideal optimal state. Under the same working condition, the optimal position of the counterweight unit 31 can be one or more.

[0122] In actual operation, the swing state of the cable 1 and the rope clamp assembly 2 can be detected to analyze whether the current swing state of the cable 1 and the rope clamp assembly 2 is in the optimal state. In this embodiment, the comparison and adjustment methods of Examples 7 and 8 can be adopted, that is, the determination and adjustment can be performed by deducing and simulating through a database. Alternatively, the optimal position can be continuously tested by comparing the frequency and using a stepless adjustment method. Both adjustment methods are methods for adjusting the position of the counterweight unit 31 when the control center's determination structure is in the adjustment signal. Therefore, it can be seen that when the detection result is an 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 during the process of converting the adjustment signal to a termination signal. Therefore, regardless of the method used to adjust the adjustment signal to a termination signal, the starting position and the final position of the counterweight unit 31 are recorded by the acquisition module each time. At the same time, the initial swing signal values ​​of the cable 1 and the rope clamp assembly 2 received during the adjustment process are also recorded. The initial swing signal values ​​of the cable 1 and the rope clamp assembly 2 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.

[0123] 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 the new input data, it compares the input data 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 directly to the signal transceiver unit 37, thereby avoiding the steps of deduction and stepless trial required in Examples 7 and 8, and obtaining the position information of counterweight unit 31 more quickly.

[0124] 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 optimal state, the input data corresponds to the comparison data, which means that this working condition has been encountered before. Due to the different positions of the counterweight unit 31, there is no difference in the values ​​and the comparison is not successful. Therefore, the initial input data is updated to the set of comparison data. This means that when the input data received subsequently is the same as the input data received this time, or is the same as the corresponding data in the comparison data, the final position in the set of comparison data can be directly output, thereby realizing the function of continuous updating and improvement. At the same time, as the elevator is continuously used, this method can also ensure real-time data updating with higher accuracy.
