Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a bridge rotation anti-overturning device. Background Technology

[0002] During bridge construction, when a bridge needs to cross existing lines (such as railways, highways, etc.) or other obstacles, the bridge rotation construction technique is often used. Bridge rotation construction involves casting or assembling the bridge structure at a position other than the design axis, and then rotating it to the design axis position using a rotation system.

[0003] However, during bridge rotation, the bridge is at risk of overturning due to structural imbalances, construction errors, and external environmental factors (such as wind and seismic forces). If a bridge overturns, it will cause enormous economic losses and serious safety accidents, affecting the normal use of the bridge and the safety of the surrounding environment.

[0004] Currently, existing bridge rotation anti-overturning devices have certain limitations in structural design and functional implementation. Some devices are complex in structure, making installation and maintenance difficult; others lack the ability to monitor and correct imbalances and tilts, failing to prevent bridge overturning in a timely and effective manner. Therefore, there is an urgent need for a device that is simple in structure, reliable, and can effectively prevent bridge overturning during rotation. Utility Model Content

[0005] The purpose of this invention is to provide a bridge rotation anti-overturning device. This device has a stable and reliable structure, strong self-adjustment capability, firm connection, and convenient installation and maintenance. It can monitor and correct the imbalance during the bridge rotation process in real time, effectively reducing the risk of bridge overturning.

[0006] To achieve the above objectives, this utility model provides a bridge rotation anti-overturning device, including a first turntable and a second turntable, which are coaxially arranged and connected by a connecting mechanism. The connecting mechanism includes a support component and a connecting component, and the support component and the connecting component are fixedly connected.

[0007] Preferably, the connecting assembly includes a slide rail, a first slider, a connecting unit, and a correction unit. The first slider is placed inside the slide rail and slidably connected to the slide rail, and a correction unit is installed at the bottom of the first slider. The connecting unit is connected to the slide rail and the first slider respectively, and the slide rail is fixedly connected to the second turntable.

[0008] Preferably, there are four correction units, all with the same structure. Each correction unit includes a ball bearing, a connecting plate, a hydraulic cylinder, a telescopic rod, a pressure sensor, and a spring. The connecting plate has a slot, and part of the ball bearing is placed in the first slot. A pressure sensor is fixedly installed below the ball bearing. The bottom of the connecting plate is connected to two telescopic rods and a hydraulic cylinder. The side wall of the hydraulic cylinder is connected to two support plates. The other end of the telescopic rod is fixedly connected to the support plate. A spring is fitted over the telescopic rod. One end of the spring is fixedly connected to the connecting plate, and the other end is fixedly connected to the support plate.

[0009] Preferably, there are two sets of connecting units, which are respectively placed on both sides of the slide rail and the first slider. The two sets of connecting units have the same structure. The connecting unit includes a connecting rod, and the two sides of the connecting rod are respectively fixedly connected to the second slider. The second slider is placed in the second slot of the slide rail side wall and the third slot of the first slider side wall.

[0010] Preferably, the support component includes a support leg, the upper part of which is fixedly connected to the first turntable, and the lower part of which is fixedly connected to the first slider by bolts.

[0012] Therefore, the present invention employs the above-mentioned bridge rotation anti-overturning device, which has the following beneficial effects:

[0013] (1) Through the coaxial arrangement of the first turntable and the second turntable, and the synergistic effect of the support components and connecting components in the connecting mechanism, the weight and various loads of the bridge during the rotation can be effectively borne, ensuring the structural stability of the bridge during the rotation process and reducing the risk of overturning.

[0014] (2) The combination of components such as ball bearings, hydraulic cylinders, telescopic rods and springs in the correction unit can monitor the unbalanced state of the bridge in real time during the bridge rotation process, and correct the tilt of the bridge in a timely manner by automatically adjusting the position and angle of the first slider, thereby improving the adaptability of the device to different working conditions.

[0015] (3) The connecting unit is connected to the slots of the slide rail and the first slider through the connecting rod and the second slider respectively, which enhances the connection strength between the slide rail and the first slider, prevents derailment or displacement during rotation, and ensures the reliability of the device.

[0023] Example 1

[0024] like Figures 1-2 As shown, this utility model provides a bridge rotation anti-overturning device, including a first turntable 1 and a second turntable 2, which are coaxially arranged. The first turntable 1 and the second turntable 2 serve as the foundation of the bridge rotation structure, bearing the weight of the bridge during rotation and various loads, and providing a base platform for the installation of other components. The first turntable 1 and the second turntable 2 are connected by a connecting mechanism, which includes a support component and a connecting component, with the support component and the connecting component fixedly connected. The connecting mechanism connects the first turntable 1 and the second turntable 2, serving a dual function of support and connection, ensuring the relative position of the first turntable 1 and the second turntable 2 during rotation, and simultaneously transmitting forces during rotation to prevent the bridge from overturning.

[0025] The connecting assembly includes a slide rail 4, a first slider 5, a connecting unit, and a straightening unit. The first slider 5 is placed inside the slide rail 4 and slidably connected to it. The first slider 5 connects the support assembly and the connecting unit, serving to transmit and convert force, and adapts to relative displacement during bridge rotation through its sliding within the slide rail 4. A straightening unit is installed at the bottom of the first slider 5, which can adjust the position and angle of the first slider 5 in a timely manner to prevent bridge overturning. The connecting unit is connected to both the slide rail 4 and the first slider 5, preventing the first slider 5 from derailing or shifting within the slide rail 4 and ensuring the reliability of the connection. The slide rail 4 is fixedly connected to the second turntable 2, and the slide rail 4 is symmetrically arranged in a stepped shape. The slide rail 4 provides a sliding track for the first slider 5, restricting its movement direction so that it can only slide along the slide rail 4. Simultaneously, because the slide rail 4 is fixedly connected to the second turntable 2, the force from the second turntable 2 can be transmitted to the first slider 5 and other components. The stepped symmetrical arrangement of the slide rail 4 increases the structural stability and the constraint on the slider.

[0026] The correction unit is placed inside the cavity of the slide rail 4. There are four correction units, all with the same structure. Each correction unit includes a ball bearing 9, a connecting plate 10, a hydraulic cylinder 8, a telescopic rod 13, a pressure sensor 11, and a spring 12. The connecting plate 10 has a first slot, in which part of the ball bearing 9 is placed and extends out of the cavity. The pressure sensor 11 is fixedly installed below the ball bearing 9. The pressure sensor 11 is used to monitor the pressure on the ball bearing 9 in real time and provide data support for correction. The bottom of the connecting plate 10 is connected to two telescopic rods 13 and a hydraulic cylinder 8. The side wall of the hydraulic cylinder 8 is connected to two support plates 14. The other end of the telescopic rod 13 is fixedly connected to the support plate 14. The telescopic rod 13 is covered with a spring 12. One end of the spring 12 is fixedly connected to the connecting plate 10, and the other end is fixedly connected to the support plate 14. Pressure sensor 11 is electrically connected to the control system, which in turn is electrically connected to hydraulic cylinder 8. When an imbalance occurs during bridge rotation, causing uneven force on the first slider 5, the pressure on the ball bearing 9 changes, and pressure sensor 11 transmits the signal to the control system. Based on the pressure change, the control system controls the extension and retraction of hydraulic cylinder 8 and the compression or extension of spring 12. This, in turn, drives the ball bearing 9 and the first slider 5 to make fine adjustments via connecting plate 10, restoring the first slider 5 to its balanced position and thus ensuring the stability of the bridge.

[0027] Two sets of connecting units are positioned on either side of the slide rail 4 and the first slider 5, respectively. Both sets of connecting units have identical structures. Each connecting unit includes a connecting rod 6, with second sliders 7 fixedly connected to both sides of the connecting rod 6. The second sliders 7 are respectively positioned in a second slot on the side wall of the slide rail 4 and a third slot on the side wall of the first slider 5. The second slider in the third slot is fixedly connected to the third slot, while the second slider in the second slot is slidably connected to the second slot. Through the cooperation of the slots and sliders, the slide rail 4 and the first slider 5 are firmly connected together. During rotation, the connecting unit moves along with the sliding of the first slider 5 within the slide rail 4, simultaneously transmitting and bearing force.

[0028] The support assembly includes a support leg 3, which is fixedly connected to the first turntable 1 at the top and to the first slider 5 at the bottom via bolts. During bridge rotation, the support leg 3 transfers the weight of the first turntable 1 and other loads to the first slider 5. The first slider 5 then transfers the force to the second turntable 2 via a connecting assembly, thus achieving force transmission and structural stability.

[0029] When using the bridge rotation anti-overturning device provided by this utility model, the pressure sensor 11 and control system are first activated before the bridge rotates to initialize and test the device, ensuring that all components are working properly. During the bridge rotation process, the pressure sensor 11 monitors the pressure on the ball bearings 9 in real time. When the bridge becomes unbalanced or tilts, the pressure on the ball bearings 9 changes, and the pressure sensor 11 transmits the signal to the control system.

[0030] The control system analyzes and determines the direction and degree of bridge tilt based on pressure changes, and then controls the extension and retraction of hydraulic cylinder 8 and the compression or extension of spring 12. The extension and retraction of hydraulic cylinder 8 and the action of spring 12 drive ball bearing 9 and first slider 5 through connecting plate 10 to make fine adjustments, so that first slider 5 returns to the equilibrium position, thereby adjusting the tilt state of the bridge. At the same time, first slider 5 slides within slide rail 4 as the bridge rotates, and second slider 7 of connecting unit moves accordingly within slot, ensuring stable connection between slide rail 4 and first slider 5 and normal force transmission.

[0031] Therefore, this utility model adopts the above-mentioned bridge rotation anti-overturning device, which has a stable and reliable structure, strong self-adjustment capability, firm connection, convenient installation and maintenance, and can monitor and correct the unbalanced state during the bridge rotation process in real time, effectively reducing the risk of bridge overturning.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
