[0002] With the continuous improvement of China's economic strength, the investment in infrastructure has been increasing, and the construction of highways and railways has entered the fast lane. Many newly built highways and railways need to cross existing highways, railways, or deep mountain valleys and other areas. When there are intersections on the line, especially railways and highways, as the arteries of the motherland, they cannot be easily interrupted. With the progress of science and technology, bridge swing construction has emerged. The cross-highway and railway bridge projects that used to take hundreds of days to build are now prefabricated in advance and the bridge swing construction is concentrated in a few hours, minimizing the impact of bridge construction on existing lines and being more and more popular among the people.

[0003] In the existing bridge swing construction method, in bridge construction, the existing swing method construction mainly completes through manual operation of machinery, generally using jacks to push and pull the swing. The advancing speed of the jacks is largely based on the experience of on-site observers and operators, with a certain degree of uncertainty. Due to the large self-weight of the beam body, the upper beam body is suspended in the air, the gravity at both ends of the bridge is not equal, and with uncontrollable factors such as wind, earthquake, and foundation settlement, the forces on the swing bearing are uneven. If there is a center of gravity offset during the swing process, the swing bridge may overturn, posing a safety hazard. Summary of the Utility Model

[0033] Refer to in combination Figures 1 to 7As shown in the figure, according to an embodiment of the present invention, an intelligent numerically controlled anti-overturning rotating support is provided, which includes a rotating support upper seat plate 1 and a rotating support lower seat plate 2. The rotating support lower seat plate 2 is fixedly connected to the ground foundation layer. The rotating support upper seat plate 1 is rotatably connected to the rotating support lower seat plate 2. The rotating support upper seat plate 1 is used to carry the bridge to be rotated 3, and the bridge to be rotated 3 rotates together with the rotating support upper seat plate 1. A plurality of limit connection devices are arranged at the abutting position of the outer edges of the rotating support upper seat plate 1 and the rotating support lower seat plate 2. The limit connection devices are used to limit the axial or radial displacement of the rotating support upper seat plate 1 relative to the rotating support lower seat plate 2. The rotating support upper seat plate 1 can rotate within the range defined by the limit connection devices. By arranging a plurality of limit connection devices, the rotating support upper seat plate 1 and the rotating support lower seat plate 2 are connected as a whole, so that the rotating support upper seat plate 1 rotates within the range defined by the limit connection devices. When the weights at both ends of the bridge are inconsistent and the rotating bridge tilts to one side, the limit connection devices can provide anti-overturning tensile force and anti-overturning supporting force for the rotating support upper seat plate 1. The rotating support upper seat plate 1 is used to carry the bridge to be rotated 3. When the bridge rotates, the bridge to be rotated 3 rotates together with the rotating support upper seat plate 1. Thus, the rotating support has the ability to resist bias pressure and anti-overturning of the rotating bridge, effectively avoiding the abnormal rotation caused by the deviation of the rotating position of the rotating support upper seat plate 1 due to the deviation of the bridge during the bridge rotation process, and even avoiding the safety accident of bridge overturning due to excessive deviation.

[0034] Specifically, the intelligent numerically controlled anti-overturning rotating support is a spherical rotating support or a pot-type rotating support.

[0035] Specifically, a numerically controlled slideway vertical sensor 12 is further arranged on the rotating support lower seat plate 2.

[0036] In a specific embodiment, the limit connection device is a chuck 4. The chuck 4 includes an L-shaped clamping part connected to the rotating support upper seat plate 1. The L-shaped clamping part is adapted to a clamping groove 24 arranged on the rotating support lower seat plate 2, and the L-shaped clamping part is in clearance fit with the clamping groove 24. The limit connection device is designed into a chuck 4 structure. The horizontal end of the L-shaped clamping part is inserted into the clamping groove 24 on the rotating support lower seat plate 2 for concave-convex fit, and a certain gap is reserved on the connection surface, which can improve the rotation efficiency. The L-shaped clamping part can be fixedly connected to the rotating support upper seat plate 1 by welding. The structure is simple and the installation is convenient, and it can effectively limit the rotating support upper seat plate 1.

[0037] In a specific embodiment, the rotating support upper seat plate 1 is rotatably connected to the rotating support lower seat plate 2 through a rotating shaft 26. By adding the rotating shaft 26, the rotation of the rotating support upper seat plate 1 and the rotating support lower seat plate 2 is made smoother, and anti-overturning is prevented.

[0038] Specifically, the rotating shaft 26 can be a protrusion provided on the lower seat plate 2 of the rotating body support, which is adapted to the concave cavity of the upper seat plate 1 of the rotating body support to achieve the rotation function. Alternatively, both the upper seat plate 1 and the lower seat plate 2 of the rotating body support are provided with matching concave cavities, and a movable rotating shaft 26 is arranged in the concave cavity. A sealing cover plate 27 is arranged at the top of the movable rotating shaft 26 to realize the rotating connection, with a simple structure and convenient operation.

[0039] In a specific embodiment, the limit connection device is a caliper 5. The caliper includes a U-shaped limit portion and a fixing portion. The U-shaped cavity of the U-shaped limit portion is used to limit the upper seat plate of the rotating body support, and the fixing portion is fixedly connected to the lower seat plate 2 of the rotating body support. Designing the limit connection device as a caliper 5 structure makes the connection more convenient and the disassembly and assembly simpler and more convenient.

[0040] In a specific embodiment, at least one of the two opposite inner wall surfaces of the U-shaped limit portion is provided with a gap adjusting device 501, and the gap adjusting device 501 is used to adjust the gap between the upper seat plate 1 of the rotating body support and the inner wall surface of the U-shaped limit portion. During the general construction process, due to uncertain factors such as foundation settlement, wind speed and wind direction, the rotation of the upper seat plate 1 of the rotating body support during the rotation process cannot be in the horizontal direction, and the distance between it and the lower seat plate 2 of the rotating body support is not constant. When the reserved rotation gap of the U-shaped limit portion is too large, it is not conducive to the limiting effect of the upper seat plate 1 of the rotating body support. When the reserved rotation gap of the U-shaped limit portion is too small, it is not conducive to the rotation of the upper seat plate 1 of the rotating body support. Therefore, a gap adjusting device 501 is arranged between the U-shaped limit portions, and the height of the gap adjusting device 501 is appropriately adjusted according to the actual operating conditions to adjust the rotation space defined by the U-shaped limit portion.

[0041] Specifically, the gap adjusting device 501 is a locking oil cylinder. A limit plate is installed on the locking oil cylinder, and the oil cylinder pushes the limit plate to lock with the upper seat plate 1 of the rotating body support for emergency braking to prevent the rotating body bridge from overturning when the center of gravity shifts.

[0042] In a specific embodiment, a numerical control rotation information acquisition device 101 is arranged on the peripheral side of the upper seat plate 1 of the slewing bearing. The numerical control rotation information acquisition device 101 includes a slide rail adapted to the peripheral side of the upper seat plate 1 of the slewing bearing and a slider capable of sliding on the slide rail. A sensor is arranged on the slider. The sensor is used to detect the movement track of the slider and transmit the movement track to the bearing control system, so as to obtain the rotation angle of the bridge to be slewed 3. In the prior art, a strip structure with scales is usually pasted on the side wall of the slewing bearing. The rotation angle of the bridge is observed manually by observing the scale value of the rotation angle. At the end of the critical slewing, manual observation is very important. Otherwise, if there is a slight mistake, the bridge will rotate too much. It is necessary to rotate in the reverse direction again, which brings unnecessary trouble to the construction. And this method has low accuracy and human factors cannot be avoided. In this application, the numerical control rotation information acquisition device 101 is arranged on the peripheral side of the upper seat plate 1 of the slewing bearing. Its slide rail is installed on the upper seat plate 1 of the slewing bearing, and the slider is connected to the base layer or the lower seat plate 2 of the slewing bearing. When the upper seat plate 1 of the slewing bearing rotates, the slider will move along the slide rail. The displacement sensor arranged on the slider will record the moving distance of the slider. According to the detection data of the sensor, the data is transmitted to the bearing control system, and the current rotation angle can be accurately calculated according to the calculation. And this rotation angle is transmitted to the bearing control system all the time. That is to say, the bearing control system can monitor the current rotation angle of the bridge all the time. It improves the measurement accuracy, simplifies the construction method, improves the construction efficiency, shortens the construction period, and effectively avoids the intervention of human factors.

[0043] In a specific embodiment, when the upper seat plate 1 of the slewing bearing and the lower seat plate 2 of the slewing bearing are of a double-plane rotation structure, the upper seat plate 1 of the slewing bearing and the lower seat plate 2 of the slewing bearing are rotationally connected through an intermediate connecting plate. A bearing slide plate 15 is arranged between the upper seat plate 1 of the slewing bearing and the intermediate connecting plate, and a stainless steel plate 29 is arranged between the intermediate connecting plate and the lower seat plate 2 of the slewing bearing. The double-plane radial sliding anti-overturning bearing is suitable for the unbalanced force slewing construction of the bridge when the weights at both ends of the slewing bridge are different. In the prior art, the bearing slide plate 15 and the stainless steel plate 29 are usually arranged on the same side of the intermediate connecting plate. When overturning occurs during the slewing process and the bearing slide plate 15 cannot slide, the stainless steel plate 29 cannot slide either, resulting in the failure of the rotational relationship between the upper bearing plate and the lower bearing plate and the inability to complete the slewing work. In this application, the bearing slide plate 15 and the stainless steel plate 29 are arranged separately. When slewing, as long as one of the bearing slide plate 15 and the stainless steel plate 29 can keep sliding, the slewing bearing can operate normally, improving the overall working efficiency of the slewing bearing.

[0044] Specifically, a rubber plate is also provided between the lower seat plate 2 of the slewing bearing and the stainless steel plate 29. When the upper seat plate 1 of the slewing bearing is unevenly stressed, the rubber plate provides a buffering effect to prevent the overall overturning of the bearing. Through the compression deformation of the elastic rubber plate, the bearing has a controllable rotation angle to achieve the leveling function.

[0045] In a specific embodiment, the intelligent numerically controlled anti-overturning slewing bearing further includes a bearing embedded bracket 16. A bearing embedded plate 17 is provided at the top of the bearing embedded bracket 16. The bearing embedded plate 17 is provided with a concrete pouring hole 18, a concrete exhaust hole 19, a temporary sealing strip 20 for the grouting groove, a sealing ring 21, and a grouting pipe 22. Before installing the anti-overturning bearing, first install the bearing embedded bracket 16, then pour concrete, remove the floating slurry on the bearing embedded plate 17, remove the temporary sealing strip 20 for the grouting groove, install the anti-overturning bearing, and then grout into the grouting pipe to ensure that the anti-overturning bearing is closely attached to the bearing embedded plate 17.

[0046] Specifically, a sensor data pipe 23 is also provided on the bearing embedded plate 17. The bearing embedded bracket 16 is connected to the lower seat plate 2 of the slewing bearing through anchor bolts 25.

[0047] Specifically, a data line conduit 14 is provided on the bearing embedded bracket 16 for installing data lines.

[0048] This application also provides an intelligent numerically controlled anti-overturning slewing system, which includes the above-mentioned intelligent numerically controlled anti-overturning slewing bearing, and also includes a data information acquisition system and an intelligent control system. The intelligent control system automatically adjusts the intelligent numerically controlled anti-overturning slewing bearing according to the slewing data collected by the data information acquisition system. Through the data information acquisition system and the intelligent control system, data information acquisition devices are arranged at positions such as the upper layer of the bridge, the bearing layer, and the foundation layer to collect various relevant parameters during the bridge slewing process, and all relevant data are systematically analyzed and sorted, and intelligent control is carried out according to the relevant data information. Construction workers and managers can easily complete the construction monitoring during the bridge construction process and the bridge slewing construction under intelligent numerical control, improving the construction efficiency during the bridge construction process and making the bridge slewing process safer and more stable. Through technological innovation and precise control, the traditional mode of increasing the size of the slewing bearing and thickening the bridge pier to improve the safety factor of the bridge slewing is achieved through data collection, analysis, and intelligent control to achieve the purpose of precise control. By reducing the outer dimensions of the slewing bearing and the turntable bridge pier, the construction cost is reduced, the safety is improved, the construction period is shortened, and the construction informatization and intelligence are realized, which has good economic and social benefits.

[0049] The data information acquisition system includes a numerically controlled longitudinal information acquisition device 7 disposed on one side of the numerically controlled hydraulic support foot 6, which is used to collect the longitudinal displacement between the upper pier 8 of the bridge and the slideway 31. Due to the large weight of the bridge body, the longitudinal force on the rotating support is the main force direction, and there is a small deviation at the bottom of the intelligent numerically controlled anti-overturning rotating support (for example, the distance between the left ground foundation layer 9 and the upper pier 8 of the bridge is greater than the other side). A small deviation at the bottom, when reflected in the bridge body, will become very large, seriously affecting the successful docking of the bridge rotation. Therefore, a numerically controlled longitudinal information acquisition device is installed on one side of the numerically controlled hydraulic support foot 6 to collect the longitudinal displacement in the circumferential direction of the intelligent numerically controlled anti-overturning rotating support, comprehensively analyze the deviation direction, and automatically control the height of the numerically controlled hydraulic support foot 6 through the system to achieve equipment leveling and ensure that the bridge body always rotates along the predetermined direction during the rotation construction process. When judging the center of gravity deviation of the bridge 3 to be rotated during force application, the electronic dial indicator 30 on the slideway 31 monitors the sliding of the bridge rotation, and analyzes whether the attitude control during the bridge rotation is within the safe range through the change in the distance between the upper pier 8 of the bridge and the slideway 31.

[0050] A vertical bearing capacity information acquisition device 10 disposed on the lower seat plate 2 of the rotating support is used to detect the vertical bearing capacity of the intelligent numerically controlled anti-overturning rotating support. After the support of the rotating support is completed, a gravity test experiment is often required to ensure that the rotating support meets the bearing requirements of the bridge body. By setting a vertical bearing capacity information acquisition device 10 on the lower seat plate 2 of the rotating support, the bearing condition of the lower seat plate 2 of the rotating support can be accurately measured and the data can be transmitted to the intelligent control system for system monitoring and adjustment. The measurement is accurate and the efficiency is high.

[0051] A transverse shear force information acquisition device 13 disposed on both sides of the lower seat plate 2 of the rotating support is used to detect the transverse shear force received by the intelligent numerically controlled anti-overturning rotating support. When encountering transverse influencing factors such as wind resistance, a transverse shear force will be generated. By monitoring the transverse shear force received by the intelligent numerically controlled anti-overturning rotating support through the transverse shear force information acquisition device 13, it is convenient for the intelligent control system to adjust the rotation speed and each matching component to ensure the smooth closure of the bridge.

[0052] A concrete stress sensor disposed in the ground foundation layer 9 is used to detect the bearing capacity of the ground foundation layer 9. As the main load-bearing layer, the ground foundation layer 9 plays a crucial role. By installing a concrete stress sensor in the ground foundation layer 9, the concrete bearing condition of the ground foundation layer 9 can be monitored at all times. Once abnormal data is found, the construction is stopped and corresponding rescue measures are taken to avoid the danger of bridge collapse.

[0053] The foundation settlement monitor is set on the ground foundation layer 9 and is used to monitor ground settlement. Ground settlement is also a top priority in construction risks. During the construction process, due to water level factors, it is often necessary to drain groundwater. However, after draining groundwater, it will inevitably affect the ground foundation layer 9. Through the foundation settlement monitor, the foundation settlement situation can be monitored at all times to ensure construction safety.

[0054] Specifically, the numerical control hydraulic support feet 6 on the outer slideway 31 of the intelligent numerical control anti-overturning slewing bearing are used to automatically adjust the support height according to the slewing data to keep the center of gravity of the slewing bridge in a safe state.

[0055] Specifically, the data collected by the intelligent numerical control slewing bearing is transmitted to the data analysis system and the Internet of Things big data cloud computing platform in real time to generate various data such as 3D simulation images, the stress state, balance state, structural stress changes, and spatial postures of the bridge slewing structure, which are displayed on the terminal device of the project command center or on the mobile terminal through the APP applet. When relevant personnel set it to the automatic mode, devices such as the numerical control hydraulic support feet 6 and the numerical control leveling and locking device automatically enter the working state to ensure the safety of the slewing bridge during the construction process and the slewing process.

[0056] Specifically, the intelligent numerical control anti-overturning slewing bearing is automatically adjusted according to the slewing data collected by the data information collection system, including the process control during bridge slewing and the intelligent identification and control of real-time state risk factors of the bridge.

[0057] In a specific embodiment, the intelligent control system includes the numerical control hydraulic support feet 6 arranged on the outside of the intelligent numerical control anti-overturning slewing bearing, which are used to automatically adjust the support height according to the slewing data. The numerical control hydraulic support feet 6 realize the adjustment of their height through the hydraulic adjustment function. Because during the slewing process, affected by various factors such as ground flatness, bearing offset, wind resistance, and ground settlement, the height of the numerical control hydraulic support feet 6 from the ground is constantly changing. The numerical control hydraulic support feet 6 are designed to be able to adjust their height arbitrarily, enabling real-time monitoring and timely adjustment during the slewing process. It is more intelligent and effectively improves the construction safety. In the bridge construction project, by checking the force monitoring data of the numerical control hydraulic support feet 6, the construction can be assisted to keep the center of force from shifting. During the bridge slewing process, when the center of gravity of the beam body shifts due to crosswinds or other situations during the rotation of the beam body, the numerical control mobile hydraulic support feet automatically start working to give an appropriate jacking force to correct the deviation and level it, ensuring that the force application point is at the center position and assisting the beam body to rotate to the designated position.

[0058] In a specific embodiment, the intelligent control system further includes a numerically controlled leveling and locking device 11, which is arranged outside the numerically controlled hydraulic support leg 6 and is used to adjust the gap between the top of the numerically controlled leveling and locking device 11 and the upper pier 8 of the bridge according to the rotation data, so that the top of the numerically controlled leveling and locking device 11 is in close contact with the upper pier 8 of the bridge. When the span of the bridge to be rotated 3 exceeds a certain value, simply using the intelligent numerically controlled anti-overturning rotating support and the numerically controlled hydraulic support leg 6 can no longer meet the support requirements. A circle of numerically controlled leveling and locking devices 11 is arranged around the numerically controlled hydraulic support leg 6 to assist in supporting and improve the stability of the rotation of the long-span bridge.

[0059] Specifically, when the bridge rotates, the intelligent control system controls the oil cylinder piston on the numerically controlled leveling and locking device to contract inward, and the height of the numerically controlled leveling and locking device decreases, creating a gap between the top and the upper pier 8 of the bridge to facilitate the rotation of the bridge. When encountering dangerous factors or after the rotation is completed, the numerical control system controls the numerically controlled leveling and locking device to increase its height and closely fit with the upper pier of the bridge to provide support force.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
