技术领域technical field
本实用新型属于桥梁水平位移测量技术领域，尤其涉及一种磁悬浮式支座水平位移测量装置。The utility model belongs to the technical field of bridge horizontal displacement measurement, in particular to a magnetic suspension type support horizontal displacement measurement device.
背景技术Background technique
在斜拉桥、悬索桥、连续刚构这类大跨度桥梁当中，支座传递上部结构主梁与桥墩之间作用的重要构件。对于可纵向滑动的支座，不仅具备传递竖向力的作用，同时还可提供主梁顺桥向自由伸缩滑动的功能，以满足因温度变化而引起的主梁纵向伸缩需求。如果支座的纵向滑动功能受限，则会影响到桥梁上部结构的自由伸缩，进而在主梁内部产生内力，影响结构的整体受力。支座实际状态下的纵向滑动水平位移是反映支座纵向滑动工作状态的直接指标，也是评价支座滑动性能的重要指标。在大跨度桥梁的荷载试验或健康监测当中，支座水平位移的测量或监测是必做项目。目前桥梁工程领域内并没有支座水平位移测试的专用传感器，通常的测量方法是在桥墩顶面设置固定台座，在台座和主梁之间安装位移计来进行测试。但是，这种方法受到位移计量程的限制，通常无法满足具有大伸缩变形的桥梁的需求，而且这种方法需要在墩顶和梁底分别安装台座，涉及到现场钻孔安装，操作十分不便；同时，位移计方法是利用桥墩当做固定点，在高墩的情况下，桥墩墩顶本身就存在纵向的水平位移，对测量得到数据会有较大的影响，所测数据并非主梁在支座处的绝对水平位移。为此，要低成本、精准、快速测量支座处的绝对水平位移变得十分困难，也是目前桥梁检测工程领域的一大技术难题。In long-span bridges such as cable-stayed bridges, suspension bridges, and continuous rigid frames, the bearing is an important component that transmits the action between the main girder of the superstructure and the pier. For the vertically slidable support, it not only has the function of transmitting vertical force, but also provides the function of free telescopic sliding of the main girder along the bridge direction, so as to meet the longitudinal expansion and contraction requirements of the main girder caused by temperature changes. If the longitudinal sliding function of the support is limited, it will affect the free expansion and contraction of the bridge superstructure, and then generate internal force inside the main girder, affecting the overall force of the structure. The horizontal displacement of the longitudinal sliding in the actual state of the bearing is a direct index reflecting the working state of the longitudinal sliding of the bearing, and is also an important index for evaluating the sliding performance of the bearing. In the load test or health monitoring of long-span bridges, the measurement or monitoring of the horizontal displacement of the bearing is a must. At present, there is no special sensor for the horizontal displacement test of the support in the field of bridge engineering. The usual measurement method is to set a fixed pedestal on the top surface of the pier, and install a displacement meter between the pedestal and the main girder for testing. However, this method is limited by the displacement measurement range, and usually cannot meet the needs of bridges with large expansion and contraction deformations. Moreover, this method needs to install pedestals on the pier top and beam bottom separately, which involves on-site drilling and installation, and the operation is very inconvenient; At the same time, the displacement meter method uses the bridge pier as a fixed point. In the case of a high pier, the top of the pier itself has a longitudinal horizontal displacement, which will have a greater impact on the measured data. The measured data is not the main girder on the support. The absolute horizontal displacement at . For this reason, it is very difficult to measure the absolute horizontal displacement at the support at low cost, accurately and quickly, and it is also a major technical problem in the field of bridge inspection engineering.

具体实施方式detailed description
1.基本结构1. Basic structure
如图1所示，磁悬浮式支座水平位移测量装置，主要由磁悬浮轨道1和屏蔽套筒5组成；磁悬浮轨道水平安装于屏蔽套筒内，磁悬浮轨道上安装有悬浮质量块2，磁悬浮轨道端部安装有测距仪4，磁悬浮轨道具有控制器3并由控制器控制为悬浮质量块提供等于其重力的恒定悬浮力。As shown in Figure 1, the horizontal displacement measuring device of the magnetic levitation support is mainly composed of a magnetic levitation track 1 and a shielding sleeve 5; A range finder 4 is installed at the top, and the magnetic levitation track has a controller 3 and is controlled by the controller to provide a constant levitation force equal to its gravity for the levitation mass.
其中，磁悬浮轨道为电磁式直线磁悬浮轨道，最大行程大于5cm，最大负载为悬浮质量块重力的2倍以上。控制器包含悬浮质量块位置检测反馈系统，对悬浮质量块恒定悬浮力控制精度小于0.1N，对悬浮质量块位置控制精度小于0.01mm。测距仪选用精度为0.01mm级的高精度测距仪，测量频率大于10Hz，用于测量悬浮质量块的相对距离变化。Among them, the magnetic levitation track is an electromagnetic linear magnetic levitation track, the maximum stroke is greater than 5cm, and the maximum load is more than twice the gravity of the suspended mass block. The controller includes a position detection feedback system of the suspended mass, the control accuracy of the constant suspension force of the suspended mass is less than 0.1N, and the control accuracy of the position of the suspended mass is less than 0.01mm. The rangefinder is a high-precision rangefinder with an accuracy of 0.01mm and a measurement frequency greater than 10Hz, which is used to measure the relative distance change of the suspended mass.
2.工作原理2. Working principle
如图2至图4所示，磁悬浮式支座水平位移测量装置直接安装于桥梁支座6的上滑动钢板，控制器控制磁悬浮轨道，在磁悬浮轨道的有效行程内，为悬浮质量块提供等于质量块重力的恒定悬浮力F。此时，悬浮质量块只受到自身重力G和磁悬浮轨道提供的竖直向上的恒定悬浮力F两个力的作用，当悬浮力始终与质量块自身重力相等时(F＝G)，质量块处于一个竖向平衡状态，悬浮质量块与磁悬浮轨道不发生接触，其绝对水平位置不会因磁悬浮轨道的移动而改变，进而形成支座水平位移测试用固定参考点。固定于支座滑动钢板上的磁悬浮轨道、屏蔽套筒随着钢板滑动产生水平位移d，此时由于质量块与轨道脱离接触，不承受任何水平力，质量块处于受力平衡状态，悬浮质量块的绝对水平位置并不随磁悬浮轨道改变，只是质量块与屏蔽套筒的水平相对位置发生改变，相对位置的改变量与屏蔽套筒水平向的位移量是相等的，即与支座上钢板的水平位移相等。通过安装于磁悬浮轨道端部的测距仪测量出位移前后质量块与屏蔽套筒相对位置的变化量ΔL，即得到支座的水平位移。如产生纵向位移前质量块与屏蔽套筒端部的水平距离为L1，产生纵向位移后质量块与屏蔽套筒端部的水平距离为L2，则支座水平位移值即为d＝ΔL＝L1-L2。利用动态测距仪连续测量，即可实现支座水平位移动态测试。As shown in Figures 2 to 4, the horizontal displacement measuring device of the magnetic levitation support is directly installed on the upper sliding steel plate of the bridge support 6, and the controller controls the magnetic levitation track to provide a mass equal to The constant levitation force F of the block gravity. At this time, the suspended mass block is only affected by its own gravity G and the vertically upward constant levitation force F provided by the magnetic levitation track. When the levitation force is always equal to the mass block’s own gravity (F=G), the mass block is at In a vertical equilibrium state, the suspension mass does not contact the magnetic levitation track, and its absolute horizontal position will not change due to the movement of the magnetic levitation track, thereby forming a fixed reference point for the horizontal displacement test of the support. The magnetic levitation track and shielding sleeve fixed on the sliding steel plate of the support produce horizontal displacement d with the sliding of the steel plate. At this time, because the mass block is out of contact with the track and does not bear any horizontal force, the mass block is in a state of force balance, and the suspended mass block The absolute horizontal position of the magnetic levitation track does not change, but the horizontal relative position of the mass block and the shielding sleeve changes, and the relative position change is equal to the horizontal displacement of the shielding sleeve, that is, the level of the steel plate on the support The displacement is equal. The rangefinder installed at the end of the magnetic levitation track measures the change ΔL of the relative position between the mass block and the shielding sleeve before and after the displacement, that is, the horizontal displacement of the support is obtained. If the horizontal distance between the mass block and the end of the shielding sleeve before the longitudinal displacement is L 1 , and the horizontal distance between the mass block and the end of the shielding sleeve after the longitudinal displacement is L 2 , then the horizontal displacement value of the support is d=ΔL =L 1 -L 2 . The dynamic test of the horizontal displacement of the support can be realized by using the continuous measurement of the dynamic distance meter.
