Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a tension synchronous multi-traction system. Background Technology

[0002] A multi-traction machine elevator system is a system design that uses multiple traction machines to drive the elevator car. It is especially suitable for high-speed, ultra-high-speed, or ultra-high-rise elevators. This design can provide higher reliability and performance. By using multiple traction machines, the maximum load capacity and speed of the elevator can be significantly increased.

[0003] Ensuring all traction machines operate with the same tension is crucial. When the tension of all traction machines is synchronized, the car moves smoothly up and down, reducing vibrations and bumps caused by asynchrony. This not only improves passenger comfort but also helps to distribute the load more evenly across the traction machines, preventing excessive wear or damage to individual machines due to overload and extending the service life of the elevator system. If the tension between the traction machines is inconsistent, the car may experience instability such as tilting and shaking during operation, seriously affecting the passenger experience and potentially causing safety accidents. It may also cause certain components to bear unnecessary additional pressure or tension, thereby increasing the risk of malfunction. Utility Model Content

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0029] This embodiment provides a tension-synchronized multi-traction system that can monitor and precisely control the tension of each traction machine in real time, thereby ensuring that multiple traction machines maintain tension synchronization during operation, ensuring smooth up and down movement of the car, reducing vibration and bumps caused by asynchrony, improving passenger comfort, and distributing the load more evenly to each traction machine, preventing excessive wear or damage to individual traction machines due to overload, and extending the service life of the elevator system.

[0030] Please see Figure 1 and Figure 2 The tension-synchronized multi-traction system includes a traction device, a detection device, and a control center. The traction device comprises several traction machines that drive the elevator car 10 up and down. The detection device monitors the tension status of the traction machines (i.e., the tension of the traction ropes 12 driven by the traction machines) in real time and transmits the detected values ​​to the control center. The control center analyzes and compares the detected values ​​in real time to determine whether the tension status of the traction machines is synchronized. It then adjusts the rotation speed of the traction sheave, thereby adjusting the tension of the traction ropes driven by the traction machines to achieve synchronization. The tension-synchronized multi-traction system provided in this embodiment achieves tension synchronization of multiple traction machines by monitoring their tension status in real time and precisely adjusting their rotation speed, ensuring smooth up and down movement of the elevator car 10 and extending the service life of the elevator system.

[0031] Specifically, the traction device includes several traction machines, and each traction machine has a traction rope 12 wound around its traction wheel 11. The traction machine drives the traction wheel 11 to rotate, which in turn drives the corresponding traction rope 12 to lift and lower the car 10.

[0032] Further, please refer to Figure 1 The traction device also includes several guide wheels 13, which are rotatably mounted on the top of the car 10. Each guide wheel 13 corresponds to one of the traction machines. The traction rope 12 is sequentially wound around the traction wheel 11 and the corresponding guide wheel 13. For example, one end of the traction rope 12 is connected to the counterweight 20, and the other end is wound around the traction wheel 11 and then around the guide wheel 13. The guide wheel 13 guides the traction rope 12.

[0033] Optionally, a guide groove is provided on the surface of the guide wheel 13, and the traction rope 12 is wound in the guide groove to prevent the traction rope 12 from crossing and tangling.

[0034] In this embodiment, a fixed seat 14 is installed on the top of the car 10, and a guide wheel 13 is rotatably mounted on the fixed seat 14. The guide wheel 13 is limited to the fixed seat 14 along its axial direction to prevent the guide wheel 13 from moving during rotation, thereby preventing the car 10 from shaking.

[0035] For compatibility, please refer to [link / reference]. Figure 1 and Figure 2 A guide shaft 15 is fixed on the fixed base 14, and a guide wheel 13 is rotatably mounted on the guide shaft 15. With the above arrangement, the guide wheel 13 is rotatably mounted on the guide shaft 15, and the two sides of the guide wheel 13 are limited in the axial direction by the fixed base 14.

[0036] Optionally, the other end of the traction rope 12 is wound around the traction sheave 11 and then around the guide sheave 13. This end is connected to a rope end spring, which is connected to the guide sheave 13. With the above arrangement, the rope end spring can absorb vibration and impact during operation, provide a certain degree of elastic buffering, reduce the instantaneous tension on the traction rope 12 during start-up and stop, protect the traction rope 12 from excessive wear, and extend its service life.

[0037] Specifically, the detection device includes several detection elements 21, each corresponding to a specific traction machine. The detection elements 21 are used to detect the tension of the traction rope 12 wound on the corresponding traction sheave 11. In this embodiment, the detection elements 21 are pressure sensors.

[0038] Please see Figure 2The detection element 21 is mounted on the guide shaft 15 and can be used to detect the pressure value applied by the guide wheel 13 to the guide shaft 15, thereby indirectly detecting the tension state of the traction rope 12. Specifically, the detection value of the detection element 21 is directly proportional to the tension state of the traction rope 12. When the tension value of the traction rope 12 increases, the corresponding detection value of the detection element 21 increases, and when the tension value of the traction rope 12 decreases, the corresponding detection value of the detection element 21 decreases.

[0039] Specifically, the control center includes a data receiving module, a data analysis module, and a command sending module. The data receiving module is connected to several detection devices 21, the data analysis module connects the data receiving module and the command sending module, and the command sending module is connected to several traction machines.

[0040] The data receiving module receives the detection values ​​from the detection components 21. The data analysis module stores standard values ​​and compares the detection values ​​of several detection components 21 with the preset standard values ​​to determine whether the tension states of several traction machines are synchronized. If they are not synchronized, the module calculates the required rotational speed to achieve synchronization based on a preset algorithm. The command sending module connects to several traction machines and sends acceleration or deceleration commands to the corresponding traction machines based on the comparison analysis results when they are not synchronized. For example, when the tension of a certain traction machine is detected to be too low, the command sending module sends an acceleration command to that traction machine to increase the rotational speed of its traction sheave, thereby increasing the traction tension. Conversely, if the tension of a certain traction machine is too high, the command sending module sends a deceleration command to reduce the rotational speed of the traction sheave on that traction machine, thereby reducing the traction tension and ensuring that the tension states of several traction machines are always synchronized.

[0041] Furthermore, the data analysis module also presets the fluctuation range of the standard value. If the detection values ​​of several detection components 21 are within the fluctuation range of the standard value, it is determined that several traction machines are synchronized. If the detection values ​​of several detection components 21 are outside the fluctuation range of the standard value, it is determined that several traction machines are not synchronized.

[0042] The tension synchronization multi-traction system provided in this embodiment is used as follows:

[0043] During installation: the traction device is accurately installed in the elevator system according to the design requirements, ensuring a secure installation and smooth operation; the detection components 21 are installed accordingly to ensure that they can accurately and sensitively monitor the tension changes of the traction rope 12; all detection components 21 are connected to the control center to complete the hardware installation; the control center is initialized, setting standard values ​​and the fluctuation range of the standard values ​​to ensure that the control center can accurately determine the tension status of several traction machines and perform corresponding control.

[0044] During operation: Detection element 21 collects data in real time and transmits this data to the data receiving module. The data analysis module compares and analyzes the detection values ​​of several detection elements 21 with preset standard values ​​to determine whether the tension states of several traction machines are synchronized. When the tension of a certain traction machine is too low, the data analysis module calculates the speed value required to adjust to the synchronization state according to the preset algorithm. The command sending module sends an acceleration command to the traction machine to increase the speed of its traction sheave, thereby increasing the traction tension. Conversely, if the tension of a certain traction machine is too high, the data analysis module calculates the speed value required to adjust to the synchronization state according to the preset algorithm. The command sending module then sends a deceleration command to reduce the speed of the traction sheave on the traction machine, thereby reducing the traction tension and ensuring that the tension states of several traction machines are always synchronized.

[0045] The tension synchronization multi-traction system provided in this embodiment can monitor and precisely control the tension of each traction machine in real time, thereby ensuring that multiple traction machines maintain tension synchronization during operation, ensuring that the car 10 moves smoothly up and down, reducing vibration and bumps caused by asynchrony, improving passenger comfort, and distributing the load more evenly to each traction machine, preventing individual traction machines from being overloaded and causing excessive wear or damage, thus extending the service life of the elevator system.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
