Description

Technical Field

[0001] The present application relates to the technical field of building shock absorption, and in particular to an electric control device for steplessly adjusting inertia parameters and an operating method thereof. Background Art

[0002] In recent years, with the development of new technologies and innovations in structural systems, cable-supported bridges have become an important structural system for super-long span bridges, and their dynamic characteristics are low and dense vibration modes. Under normal wind speed conditions, low-order modes of vertical bending vortex vibration and torsional vibration are prone to occur, such as the Yingwuzhou Yangtze River Bridge, Humen Bridge and Xihoumen Highway Bridge. Therefore, long-span bridges themselves face two types of problems: first, the measurement and evaluation of the dynamic characteristics of the bridge structure itself; second, the improvement of the vibration suppression performance of the bridge structure.

[0003] The general measure to solve the wind vibration problem and improve the vibration suppression performance of existing bridge structures is to optimize the aerodynamic shape of the main beam section through aerodynamic measures and verify it through wind tunnel experiments. However, the results of engineering practice show that this single aerodynamic measure cannot completely solve the vibration of the bridge structure. Engineers and researchers also considered setting a damper for vertical vortex vibration control between the bridge tower and the main beam. Theoretical and engineering practice results show that due to the limitation of the installation position, the conventional viscous damper only contains a damping unit and can provide a limited additional damping ratio.

[0004] As a new type of mechanical element, inertia can greatly improve the vibration reduction performance of the vertical damper at the same installation position. The wind vibration control performance of the long-span bridge is related to the inertia parameters, and the optimal inertia parameters corresponding to different vibration modes are different. Therefore, if the vertical damper of the long-span bridge wants to actively obtain better wind vibration control performance, it is necessary to consider the multi-modal control requirements and enhance the robustness of the damper. The inertia parameter adjustable device should be set for the inertia damper. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] The embodiment of the present application provides an electronic control device with stepless adjustment of inertia parameters and an operation method thereof, which can solve the problem in the related art that the damper only contains a damping unit and cannot flexibly adjust the inertia parameters to obtain better wind vibration control performance.

[0028] Since the wind-induced vibration control performance of large-span bridges is related to the inertia parameters, and the optimal inertia parameters corresponding to different vibration modes are different, if the vertical damper of a large-span bridge wants to actively obtain better wind-induced vibration control performance, it is necessary to consider the multi-modal control requirements and enhance the robustness of the damper. Therefore, an inertia parameter adjustable device connected to the damper is set.

[0030] Through this structural setting, the electronic control device with stepless adjustment of inertia parameters adjusts the generated rotational inertia by changing the first rotational inertia parameter and the second rotational inertia parameter, and the damper is connected to the device through a rack to achieve adjustable inertia parameters; wherein, the first rotational inertia parameter is determined by the rotation speed of the cross turntables on both sides, and the shaft assembly in the speed regulating box 1 can simultaneously adjust the rotation speed of the cross turntables on both sides, which ensures the coordinated movement of the two cross turntables, and the rotation speed of the two cross turntables is controlled by controlling the rotation speed of the shaft assembly, that is, changing the first rotational inertia parameter; the second rotational inertia parameter is determined by the distance between the four counterweight assemblies 4 and the motor 6, that is, the size of the circle when the four counterweight assemblies 4 distributed in a circle rotate, and the four counterweight assemblies 4 are movable and arranged on the linear moving assembly 3, and synchronously move closer to or away from the motor 6 by the power of the motor 6, that is, changing the second rotational inertia parameter; the damper solves the problem in the related art that the damper only contains a damping unit and cannot flexibly adjust the inertia parameter to obtain better wind vibration control performance by configuring this electronic control device with stepless adjustment of inertia parameters.

[0031] It should be noted that dampers are set at corresponding positions of the bridge to achieve shock-absorbing performance; the device proposed in this application acts on the inertial mass block through a rack. When the inertial mass block acts, it vibrates up and down to drive the device to rotate, thereby greatly improving its shock-absorbing performance.

[0033] In this embodiment, the design of the rotating shaft assembly uses the structure of a driving shaft 7 and a driven output shaft 8, which provides an effective way to adjust the rotation speed of the cross turntable. The driving shaft 7 is provided with a driving wheel assembly connected to the damper transmission, which is used to transmit power to the driven output shaft 8. The driven output shaft 8 is connected by corresponding meshing with the driving wheel assembly, and the gear synchronization assembly and the driven synchronization assembly are synchronously meshed through an auxiliary synchronization sleeve, so that it can rotate at a different speed from the driving shaft 7, and drive the cross turntable to rotate at a different speed. It should be noted that this embodiment explains the structure of the turntable 2, which is a cross turntable and has four branches 22; and the turntable 2 can be in a variety of structural forms, and can be a disc structure, and a plurality of branches 22 are distributed on the disc structure in a ring shape and at equal intervals.

[0034] In some preferred embodiments, the driving wheel assembly includes a brake gear 94, a first driving gear 91, a second driving gear 92 and a third driving gear 93, and all of them are fixedly connected to the driving shaft 7, and the brake gear 94 is connected to the damper through the transverse rack 19; the driven wheel assembly includes a first driven gear 101, a second driven gear 102 and a third driven gear 103 arranged in sequence, which are connected to the driven output shaft 8 through bearings, and are respectively meshed with the first driving gear 91, the second driving gear 92 and the third driving gear 93; the driven synchronous assembly includes a first driven synchronous gear 81 and a second driven synchronous gear 82; the first driven synchronous gear 81 is arranged between the first driven gear 101 and the second driven gear 102, and the second driven synchronous gear 82 is arranged between the second driven gear 102 and the third driven gear 103;

[0036] Through this structural setting, a brake gear 94 and three driving gears are fixed on the driving shaft 7. The brake gear 94 is used to connect with the damper transmission to obtain power. The three driving wheels are respectively meshed with the three driven gears at the corresponding positions on the driven output shaft 8 to drive the three driven gears to rotate. The speed ratios of the three pairs of gears are different, representing three different gears. The three driven wheels are connected to the driven output shaft 8 through bearings, so the driven gears cannot directly drive the driven output shaft 8 to rotate. Two driven synchronous gears are fixed on the driven output shaft 8, and the driven synchronous gears are designed with external splines. Similarly, the root extension of each driven gear is correspondingly designed with a gear synchronization gear, which can be connected with the internal splines designed inside the synchronization sleeve.

At this time, the driven output shaft 8 has the slowest speed, which is gear 1; when the first synchronization sleeve 111 is simultaneously meshed and connected to the first driven synchronization gear 81 and the first gear synchronization gear 1010, the second synchronization sleeve 1 When 12 are meshed and connected to the second driven synchronous gear 82, the first driven gear 101 drives the driven output shaft 8 to rotate, and the other two driven gears idle.

At this time, the speed of the driven output shaft 8 is the fastest, which is gear 3.

[0037] In some preferred embodiments, a movable engaging groove is provided on the ring side of the first synchronous sleeve 111 and the second synchronous sleeve 112; a fixed rod 12 is also horizontally provided in the speed regulating box 1, and two levers 13 are slidably connected to the fixed rod 12, and the two levers 13 are respectively engaged with or separated from the corresponding movable engaging grooves to drive the first synchronous sleeve 111 and the second synchronous sleeve 112 to slide to corresponding positions; a positioning ring 14 is slidably provided on the fixed rod 12 and on both sides of the two levers 13 to push the corresponding lever 13 to slide horizontally and limit the lever 13.

[0038] In this embodiment, the ring sides of the two synchronous sleeves are provided with movable engaging grooves, which enable the lever 13 to engage or disengage therewith and push it to the corresponding gear position. The setting of the positioning ring 14 helps to limit the sliding of the lever 13 and ensure the limit position after the operation is completed. This can prevent misoperation and improve the safety of the system. When the speed needs to be adjusted, the lever 13 can be pushed by moving the positioning ring 14 on the fixed rod 12.

[0039] In some preferred embodiments, the lever 13 is made of metal material; a fixing plate 15 is also horizontally provided in the speed regulating box 1, and two magnets 151 are provided on the fixing plate 15 to correspondingly adsorb the two levers 13 on the fixing plate 15 after the adjustment is completed.

[0042] In this embodiment, the guide rail 31 is fixed on each branch 22 to provide stable support, and the bracket 32 ​​is provided at both ends of the guide rail 31 for fixing the trapezoidal lead screw 33. The bracket is provided with a through hole to facilitate the installation and adjustment of the trapezoidal lead screw 33.

[0049] An embodiment of the present application provides an operating method of an electronic control device with stepless adjustment of inertia parameters, which includes: a damper installed on a bridge is connected to a brake gear 94 through a transverse rack 19, and drives a turntable 2 to rotate; based on adjusting a first moment of inertia parameter and a second moment of inertia parameter, the inertia parameters are adjustable.

[0050] In this method, the electronic control device for steplessly adjusting the inertia parameters is a device for adjusting the inertia parameters in cooperation with the damper. The damper is arranged between the bridge tower and the main beam, and is connected to the electronic control device through a transverse rack 19. By adjusting the first and second rotational inertia parameters, the inertia parameters can be adjusted, thereby solving the problem that the damper only contains a damping unit and cannot flexibly adjust the inertia parameters to obtain better wind vibration control performance.

[0051] The beneficial effects brought by the present invention include:

[0052] 1. The weight block 42 is controlled to move synchronously through the meshing of large and small gears and the lead screw structure to achieve stepless adjustment of the moment of inertia. Only one motor 6 is needed for the four counterweight assemblies 4 on one side to achieve precise synchronous movement, which simplifies the structure and reduces the cost.

[0053] 2. The trapezoidal lead screw 33 is used in this design to prevent the centrifugal force when the counterweight rotates from driving the lead screw to rotate, driving the motor 6 to reverse through the gear drive assembly, damaging the motor 6, and causing accidents;

[0054] 3. The relative rotation speed of the weight block 42 is adjusted by the speed regulating box 1. There are three pairs of meshing gears inside the speed regulating box 1, corresponding to three gears. When changing speed, it is only necessary to adjust the position of the first synchronous sleeve 111 and the second synchronous sleeve 112 through the lever 13. The synchronous sleeve has internal teeth. The synchronous sleeve controls the connection of the corresponding driven gear, thereby controlling which pair of gears is in effect, without having to push the heavy gears, which is convenient for manual operation.
