Description

Technical Field

[0001] The present invention relates to the technical field of bridge engineering, and particularly to a modern road and bridge device with multi-dimensional shock absorption and wind resistance. Background Art

[0002] In the construction of modern transportation infrastructure, road and bridges, as key hubs, their stability and safety are of crucial importance. With the economic development and the growth of traffic flow, bridges are facing increasingly complex and severe natural environment challenges, especially the problems of wind load and vibration, which have become key factors affecting the structural safety and service life of bridges.

[0003] The action of wind on bridges is a complex fluid mechanics problem. At present, many bridges adopt some conventional wind resistance measures in the design, such as optimizing the bridge shape, by adopting streamlined pylon, box girder and other structures to reduce wind resistance. However, this method only reduces the acting force of wind passively and cannot be dynamically adjusted according to the real-time wind direction and wind force. In the case of variable wind direction and unstable wind force, its wind resistance effect is greatly reduced.

[0004] The stability of a bridge is based on the force balance in multiple aspects. Among them, the wind load will affect the stability of the bridge body, resulting in the destruction of the dynamic force balance when the bridge body faces strong crosswind. Over the years, it will cause direct fatigue damage to the bridge structure, leading to the damage of structural components and seriously threatening the safe use of the bridge. Therefore, a modern road and bridge device with multi-dimensional shock absorption and wind resistance is proposed to solve the above problems. Summary of the Invention

[0015] Preferably, there are seven multi-dimensional shock-absorbing and wind-resistant mechanisms in total. The seven multi-dimensional shock-absorbing and wind-resistant mechanisms are arranged in an array on the windproof groove at the bottom of the bridge body.

[0016] (III) Beneficial effects: Compared with the prior art, the present invention provides a multi-dimensional shock-absorbing and wind-resistant modern road and bridge device, which has the following beneficial effects: 1. For the multi-dimensional shock-absorbing and wind-resistant modern road and bridge device, the dynamic balance part in the device can be adaptively adjusted according to multi-dimensional wind directions. When facing crosswinds, the arc-shaped structure at the bottom of the windward plate generates an upward thrust under the action of the wind force, flips with the rotation axis as the center, drives the balance arm to change the angle with the bridge body, makes the center of gravity of the bridge body shift to the windward side, generates a stable moment, dynamically changes the force balance of the bridge body. When the wind direction has an angle with the bridge body, the swing blades are affected by the wind force, drive the balance arm to flip on the round sleeve, adjust the center of gravity of the bridge body, enhance the force stability, effectively cope with the wind load of complex wind directions, and improve the wind resistance of the bridge.

[0017] 2. For the multi-dimensional shock-absorbing and wind-resistant modern road and bridge device, the detection part and the compensation part cooperate to achieve precise compensation. When the windward plate flips, the adjusting block squeezes the detection block, drives the sliding rod to slide. The distance sensor monitors the change in the distance of the detection plate, calculates the flipping angle of the windward plate. The displacement of the sliding rod drives the L-shaped rack to move. Through the gears and the rope winding drum, the pulling rope pulls the balance plate to slide, automatically adjusts the center of gravity of the bridge body according to the wind force, overcomes the flipping moment generated by the wind, and further improves the wind resistance stability of the bridge body, ensuring the safety of the bridge under the action of strong winds.

[0018] 3. For the multi-dimensional shock-absorbing and wind-resistant modern road and bridge device, the distance sensor of the detection part monitors the change in the distance related to the flipping of the detection plate and the windward plate in real time, and can calculate the real-time flipping angle of the windward plate. This helps to collect the usage conditions of the windward plate under different wind force levels, provides data support for the tracking and maintenance of the bridge, discovers potential problems in time, and ensures the continuous and effective operation of the device.

[0019] 4. The multi-dimensional shock-absorbing and wind-resistant modern road and bridge device realizes shock absorption of the bridge body vibration in multiple links. During the flipping process of the windward plate of the dynamic balance part, the direct impact of the wind force on the bridge body can be alleviated. The actions of the balance arm and the swing blade to adjust the center of gravity can reduce the swaying of the bridge body in the wind. When the windward plate resets, the shock-absorbing plate reduces the collision force between it and the outer wall of the windproof groove, alleviates the vibration. The balance plate of the compensation part adjusts its position according to the wind force, stabilizes the center of gravity of the bridge body, and reduces the vibration caused by the center of gravity deviation. The combined effect of these measures effectively reduces the vibration amplitude and frequency of the bridge body under the action of wind load, alleviates the fatigue damage, and extends the service life of the bridge.

The detection block 53 is of a triangular structure, and the inclined surface of the detection block 53 is in contact with the inclined surface of the adjusting block 42. Through holes corresponding to the positioning holes 35 are formed in the side wall of the windproof groove 2. The two sliding rods 52 both pass through the inner walls of the through holes and the inner walls of the positioning holes 35. The through holes on the mounting part 3, the dynamic balance part 4, the windproof groove 2 and the detection part 5 together form a unilateral wind-resistant mechanism. The number of unilateral wind-resistant mechanisms is two, and the other unilateral wind-resistant mechanism is symmetrically mounted on the other side of the windproof groove 2.

[0026] It should be explained that the compensation part 6 includes a cross beam 61, which is mounted between the two internal mounting plates 51 in the two unilateral wind-resistant mechanisms. Two limiting arms 62 are symmetrically connected to the top of the cross beam 61. Two balance plates 63 are slidably connected between the inner walls of the two limiting arms 62. Two supports 64 are fixedly connected to both sides of the top of the cross beam 61. Mounting holes 65 are formed on both sides of the top of the cross beam 61.

Each gear 66 meshes with the adjacent L-shaped rack 58. A tension spring is elastically connected between the two balance plates 63. The compensation part 6 is located in the windproof groove 2. The compensation part 6 and the two unilateral wind-resistant mechanisms together form a multi-dimensional shock-absorbing and wind-resistant mechanism. The number of multi-dimensional shock-absorbing and wind-resistant mechanisms is seven in total, and the seven multi-dimensional shock-absorbing and wind-resistant mechanisms are arranged in an array on the windproof groove 2 at the bottom of the bridge body 1.

[0027] Working principle: The dynamic balance part 4 is used to resist wind in multiple dimensions. When facing crosswind, the wind force will blow the windward plate 41 on one side of the bridge body 1. An upward thrust is generated through the arc surface of the windward plate 41. The windward plate 41 rotates upward with the rotating shaft 33 as the axis, driving the balance arm 45 to rotate. The angle between the balance arm 45 and the bridge body 1 is maintained in the range of zero to ninety degrees according to the wind speed. The balance arm 45 gradually tends to be in a horizontal state from a vertical state according to the wind speed, causing the center of gravity of the bridge body 1 to shift to the side of the wind direction, generating a stabilizing moment, and then dynamically changing the force balance of the bridge body 1 according to the wind speed. When a certain angle is formed between the wind direction and the bridge body 1, the wind force will blow the swing blade 46 to make the balance arm 45 rotate on the circular sleeve 44, and the rotation angle does not exceed ±30°, so that a certain angle is formed between the balance arm 45 and the oblique wind, dynamically adjusting the center of gravity of the bridge body 1 and improving the force stability.

[0028] When the windward plate 41 rotates, the adjusting block 42 will squeeze the detection block 53, causing the detection block 53 to drive the slide rod 52 to slide and approach the positioning hole 35 and the inner wall of the through hole. The detection block 53 can enter the positioning hole 35 and slide on the inner wall of the through hole. The distance sensor 55 is used to monitor the distance change of the detection plate 54 in real time, so as to calculate the real-time rotation angle of the windward plate 41, which is convenient for collecting the usage conditions of the windward plate 41 under different wind force levels, and then convenient for tracking and maintenance.

[0029] When facing strong wind, the windward plate 41 is blown to rotate ninety degrees and stick to the external mounting plate 31, and the adjusting block 42 is inserted into the groove 34 to ensure that the balance arm 45 is in a horizontal state. In a windless state, the balance arm 45 rotates and descends due to gravity, driving the windward plate 41 to rotate and reset. The shock-absorbing plate 47 contacts the outer wall of the windproof groove 2 to reduce the collision force. The spring 57 pushes the washer 56 and drives the slide rod 52, so that the detection block 53 moves along the inclined surface of the adjusting block 42 to reset, preventing the windward plate 41 from shaking and bouncing.

[0030] During the rotation of the windward plate 41 under the wind force, the displacement change of the slide rod 52 can drive the L-shaped rack 58 to move synchronously, so as to drive the winding drum 67 to rotate through the gear 66, and then pull the balance plate 63 to slide between the limiting arms 62 through the pull rope 68, so that the balance plate 63 automatically changes its position according to the wind force, further adjusting the center of gravity of the bridge body 1, and then overcoming the overturning moment generated by the wind, further improving the wind resistance stability of the bridge body 1. When there is no wind, the L-shaped rack 58 follows the slide rod 52 to reset. At the same time, the two balance plates 63 approach each other through the tension spring and gradually return to the center to restore the center of gravity of the bridge body 1.
