Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-bridge coupling, and in particular to a vehicle-bridge coupling vibration control device. Background Art

[0002] In recent years, with the development of highway transportation and bridge construction, bridge structures have become increasingly larger, lighter, and more flexible. The dynamic response of large-span highway bridges under heavy, high-speed vehicle loads has attracted increasing attention from bridge researchers. When vehicles pass over a bridge, it causes vibration. At this point, the bridge structure is subjected not only to static forces but also to moving loads and the vibration inertia of the bridge and vehicles. The vibration of the bridge superstructure caused by vehicle dynamics can fatigue structural components, reducing their strength and stability. Excessive bridge vibration can affect the operational safety and stability of vehicles on the bridge. In general, vehicle-bridge coupled vibration results in varying amplitudes of bridge deck vibration depending on the mass of the vehicle. Existing bridges cannot change the pressure at the contact point between the vehicle and the bridge deck during use, resulting in an inability to control coupled vibration. This, in turn, causes the bridge deck to vibrate excessively rapidly during vehicle travel, shortening the bridge's service life and potentially making the bridge deck dangerous during use. Based on this, the present invention designs a vehicle-bridge coupled vibration control device to address the aforementioned issues. Summary of the Invention

[0003] The object of the present invention is to provide a vehicle-bridge coupled vibration control device to solve the problem raised in the above background technology that the amplitude of the vehicle-bridge coupled vibration cannot be controlled, resulting in a shortened service life of the bridge deck.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A vehicle-bridge coupling vibration control device includes a bridge body, characterized in that: a groove is provided at the bottom of the bridge body, four telescopic rods are installed in the groove, a pressure plate is installed between the four telescopic rods, the lower end of the telescopic rod is connected to the bridge body, and the upper end of the telescopic rod is connected to the bottom of the pressure plate, a pressure device is installed on the bottom surface of the pressure plate, the fixed end of the pressure device is connected to the bridge body, and the detection end of the pressure device is connected to the pressure plate, an outer shell is installed on the bottom surface of the bridge body, a support plate is fixedly connected to the bottom surface of the inner wall of the outer shell, a plurality of electromagnetic rods are installed on the support plate, a magnetic plate is installed on the upper part of the bridge body, and a repulsive force can be generated between the electromagnetic rod and the magnetic plate, a ventilation mechanism is installed on one side of the outer shell, and a cleaning mechanism is provided on the ventilation mechanism.

[0006] The four telescopic rods are located at four corners of the bottom surface of the inner wall of the groove, and the telescopic rods are telescopic.

[0007] The magnetic plates are divided into two groups, one of which is fixedly connected to the bridge body, and the other group is slidably connected to the bridge body. The magnetic plates are located on the upper surface of the bridge body, and infrared locators are provided on the sides of the magnetic plates.

[0008] The ventilation mechanism includes a protective shell, a drive motor, a rotating column, fan blades and a filter. The protective shell is installed on one side of the shell, and the drive motor is installed in the protective shell. The shell of the drive motor is connected to the protective shell. The output end of the drive motor is fixedly connected to the rotating column. A plurality of fan blades are installed on the rotating column. The surface of the fan blades is provided with an anti-static layer. The protective shell is a tubular shell structure with one end sealed. The inner side of one end of the protective shell is connected to the filter, and the rotating column is arranged on the inner side of the filter.

[0009] The cleaning mechanism includes a fixed rod, a spring and a cleaning plate. The fixed rod is installed on the rotating column. A plurality of springs are fixedly connected to the fixed rod. A cleaning plate is installed between the plurality of springs. A brush is provided on the surface of the cleaning plate. The cleaning plate and the filter are movably connected.

[0010] The shell is provided with a plurality of ventilation holes, and dustproof nets are arranged in the ventilation holes.

[0011] Railings are installed on both sides of the bridge body, and speed alarms are provided on both sides of the railings.

[0012] A temperature monitor is arranged in the shell, and a pressure alarm is installed in the groove.

[0013] A data recorder is installed on the bottom surface of the bridge body, and the pressure gauge cooperates with the data recorder. A collection analyzer is installed on the bottom surface of the bridge body, and the collection analyzer cooperates with the data recorder. A transmitter is installed on the bottom surface of the shell, and the transmitter cooperates with the collection analyzer.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention can effectively measure the mass of the vehicle through the pressure plate. After the pressure plate measures the mass data of the vehicle, it is transmitted to the pressure device, and then the pressure device transmits the data to the data recorder. Finally, the data recorder transmits the data to the collection analyzer to judge whether the mass of the vehicle is heavy or light. When the weight of the vehicle is heavy, the data recorder controls the transmitter to start working. When the transmitter works, the transmitter controls the electromagnetic rod to work, so that the electromagnetic rod generates magnetic force, and the magnetic force acts on the magnetic plate, so that the two sets of magnetic plates are filled with opposite magnetic forces. When the magnetic forces formed by the two sets of magnetic plates are opposite, the magnetic plate connected to the bridge body is slidably connected. The plate floats up, so that the magnetic plate acts on the moving vehicle and makes the vehicle float up. When the magnetic plate drives the vehicle to move up, the two sets of magnetic plates form a hollow shape due to the opposite magnetic forces, thereby reducing the contact pressure between the vehicle and the bridge body, thereby reducing the amplitude of the bridge deck, so as to ensure that the amplitude between the vehicle and the bridge body is always maintained at a certain value, thereby controlling the vibration coupling between the vehicle and the bridge body, and further extending the service life of the bridge body, avoiding serious resonance of the bridge body caused by long-term vibration between the bridge body and the vehicle, thereby causing damage to the bridge body, and further improving the control accuracy of the equipment and the practicality of the equipment. When too many vehicles pass through the bridge deck, the electromagnetic rod and the electromagnetic plate are in a continuous working state, and the heat of the electromagnetic rod continues to rise. When the temperature of the electromagnetic rod rises, the temperature monitor issues an alarm. At this time, the drive motor drives the rotating column to rotate. When the rotating column rotates, the fan blades on the rotating column begin to rotate, and then the air flows. When the air flows into the outer shell, the flow of air can effectively cool the electromagnetic rod. When the drive motor is working, the fixed rod installed at the output end of the drive motor rotates. At this time, the spring acts on the cleaning plate, so that the cleaning plate can effectively clean the filter, so that the ventilation mechanism can clean the filter at the same time when dissipating heat to the inside of the equipment, avoiding dust clogging on the filter during filtration, thereby preventing air from entering the inside of the equipment, and then affecting the heat dissipation of the equipment. When in use, the ventilation mechanism can effectively ensure that the temperature in the outer shell is always kept appropriate, further avoiding the high temperature in the outer shell that causes the electromagnetic rod to malfunction and affect the vibration control of the bridge body.

A transmitter 11 is installed on the bottom surface of the shell 7, and the transmitter 11 cooperates with the collection analyzer 6.

[0036] Working principle:

[0037] When a moving vehicle passes through the pressure plate 3, the pressure plate 3 can effectively measure the mass of the vehicle. After measuring the mass data of the vehicle, the pressure plate 3 transmits it to the pressure device 4, and then the pressure device 4 transmits it to the data recorder 5. Finally, the data recorder 5 transmits the data to the collection analyzer 6 to determine whether the mass of the vehicle is heavy or light. When the weight of the vehicle is heavier, the data recorder 5 controls the transmitter 11 to start working. When the transmitter 11 is working, the transmitter 11 controls the electromagnetic rod 9 to work, so that the electromagnetic rod 9 generates a magnetic force, and the magnetic force acts on the magnetic plate 10. Specifically, the magnetic plate 10 itself has magnetism. After the electromagnetic rod 9 is energized, it generates a magnetic force that repels the magnetic plate 10, thereby lifting the magnetic plate 10 by magnetic force, which acts as a buffer for the bridge body. After the magnetic plate 10 is lifted, the side periphery is connected to the bridge body 1 through Kevlar fiber cloth, thereby improving the stability of the magnetic plate 10. When the magnetic forces formed by the two groups of magnetic plates 10 are opposite, the magnetic plate 10 slidably connected to the bridge body 1 floats up, so that the magnetic plate 10 acts on the moving vehicle and makes the vehicle float up. When the magnetic plate 10 drives the vehicle to move upward, the two groups of magnetic plates 10 form a hollow shape due to the opposite magnetic forces, thereby reducing the contact pressure between the vehicle and the bridge body 1, thereby reducing the amplitude of the bridge deck, thereby ensuring that the amplitude between the vehicle and the bridge body 1 is always maintained at a certain value, thereby controlling the vibration coupling between the vehicle and the bridge body 1, and further extending the service life of the bridge body 1, avoiding the serious resonance of the bridge body 1 caused by the vibration between the bridge body 1 and the vehicle for a long time, and avoiding the bridge body 1 from being easily damaged, further improving the control accuracy of the equipment and the practicality of the equipment;

[0038] As too many vehicles pass through the bridge deck, the electromagnetic rod 9 and the electromagnetic plate are in a continuous working state, and the heat of the electromagnetic rod 9 continues to rise. When the temperature of the electromagnetic rod 9 rises, the temperature monitor sounds an alarm, and the drive motor 14 drives the rotating column 15 to rotate. When the rotating column 15 rotates, the fan blades 16 on the rotating column 15 start to rotate, and then the air flows. When the air flows into the housing 7, the flow of air can effectively cool the electromagnetic rod 9. When the drive motor 14 is working, the fixed rod 18 installed at the output end of the drive motor 14 rotates. At this time, the spring 19 Acting on the cleaning plate 20, the cleaning plate 20 can effectively clean the filter 23, so that when the ventilation mechanism 12 dissipates heat inside the device, it can clean the filter 23 at the same time, avoiding dust clogging on the filter 23 during filtration, which prevents air from entering the device, thereby affecting the heat dissipation of the device. When in use, the ventilation mechanism 12 can effectively ensure that the temperature in the housing 7 is always maintained at an appropriate level, further avoiding the high temperature in the housing 7, preventing the electromagnetic rod 9 from malfunctioning due to high temperature, and avoiding affecting the vibration control of the bridge body 1. The pressure device 4 is a gravity measuring device. The side periphery of the magnetic plate 10 can be connected to the bridge body 1 through Kevlar fiber cloth, thereby improving the stability of the magnetic plate 10 after the magnetic plate 10 is pushed up by the magnetic force.
