倒锤式倾斜仪,是一种测量建筑物倾斜度的精密仪器。它的基本结构形式如图(一)所示:重锤G,通过连杆L,支立于座盘AB上。支承点D,可以用滚珠轴承形成铰的支承形式,亦可像天平一样用玛瑙刀口或金属刀口支承。为了保持重锤的平衡,连杆的两边用一组弹簧F_1和F_2,与座盘上支架相连接。支架上装有电器变换器,以反映重锤偏转角度的变化。当座盘平面AB发生倾斜时,重锤G绕支承点1)即产生一定的偏转角度,并使电器变换器的物理量产生相应的变化。所以通过测量电变换器物理量的变化,即可了解座盘平面AB发生倾斜的大小。倒锤式倾斜仪即是利用这种原理工作的。这种形式的倾斜仪可以进行长距离遥测。若将其电器变换器连接于动态记录仪上,则可进行动态测量,因此在水电等建筑工程巾得到广泛应用。本文仅对倒锤式倾斜仪的有关参数作一些讨论。
Reciprocating hammer inclinometer is a precision instrument that measures the inclination of a building. Its basic structure as shown in Figure (a) below: heavy hammer G, through the connecting rod L, stand on the seat AB. Support point D, can be formed with a ball bearing hinged support form, can also be like a balance with agate knife edge or metal blade support. In order to maintain the balance of the hammer, the two sides of the connecting rod are connected with the bracket on the seat plate by a set of springs F_1 and F_2. The bracket is equipped with electrical converters to reflect changes in weight deflection angle. When the seat pan plane AB tilt occurs, the weight G around the bearing point 1) that is a certain degree of deflection angle, and make the electrical converter physical changes corresponding. Therefore, by measuring the change of the physical quantity of the electrical converter, it is possible to understand the size of the inclination of the seat plate plane AB. Reciprocating hammer inclinometer is to use this principle to work. This type of inclinometer allows long-range telemetry. If the electrical converter connected to the dynamic recorder, you can carry out dynamic measurements, and therefore in the construction of water and electricity towels are widely used. This article only on the hammer tilt inclinometer related parameters for some discussion.
