本发明涉及一种测量辅助装置,尤其是一种操作容易、可有效提高测量效率及精确度的 套夹式测量脚架。 The invention relates to a measuring auxiliary device, in particular to a clip-on measuring tripod which is easy to operate and can effectively improve measuring efficiency and precision.
背景技术: Background technique:
在大地测量及工程测量时,需要将经纬仪、水准仪、全站仪等测量仪器安置在脚架上,一方面可以扩大仪器的测量范围,另一方面便于测量人员操作仪器。现有的脚架亦称三脚架,有 基座,基座为平板状,在基座的中心处设有竖直的螺丝等固定件,与基座相接有三个支脚,支脚的长度及与基座之间的角度均可以调整。测量时,将测量仪器通过螺丝等固定在基座上,通过调整支脚的长度及角度,使 测量仪器的基准面与测量点处的水平面一致及测量仪器的竖轴与测量点处的垂线一致。现有的脚架存在如下问题: In geodetic surveys and engineering surveys, it is necessary to place the measuring instruments such as the theodolite, the level gauge, and the total station on the tripod. On the one hand, the measuring range of the instrument can be expanded, and on the other hand, the measuring personnel can operate the instrument. The existing tripod is also called a tripod. The base has a flat shape, and a fixing member such as a vertical screw is arranged at the center of the base, and three legs are connected to the base, and the length of the leg and the angle between the leg and the base can be adjusted. When measuring, the measuring instrument is fixed to the base by screws or the like, and the length and angle of the legs are adjusted. The reference plane of the measuring instrument coincides with the horizontal plane at the measuring point and the vertical axis of the measuring instrument coincides with the perpendicular line at the measuring point. The existing tripod has the following problems:
( 1 )由于测量仪器置于基座上而与地面测量标志点分离,测量时均需要费时费力的调整,才能保证测量仪器的竖轴与通过测量标志点的垂线重合,并且需要测量仪器观测基准面与地面标志点的垂直距离,这些环节增加了测量难度而降低了工作效率,且因误差源多而降低了测量的精确度。 ( 1 Since the measuring instrument is placed on the pedestal and separated from the ground measuring mark point, it takes time and laborious adjustment to ensure that the vertical axis of the measuring instrument coincides with the vertical line passing through the measuring mark point, and the measuring instrument is required to observe the reference surface. The vertical distance from the ground marker points increases the measurement difficulty and reduces the work efficiency, and reduces the accuracy of the measurement due to the large number of error sources.
( 2 )无法应用于例如水准尺、全站仪反射棱镜标杆、 GPS (全球卫星定位系统)测量标杆等需要直立在测量标志点上的柱状测量设施,只能由测量人员手扶操作,不仅操作费时费力,而且也难以保证精确整平,从而降低了测量的精确度。 (2) cannot be applied to, for example, level gauges, total station reflector prisms, GPS (Global Positioning System for Global Positioning System) A columnar measuring facility that needs to stand upright on the measuring point, such as a pole, can only be operated by the surveyor. It is not only time-consuming and labor-intensive, but also difficult to ensure accurate leveling, thus reducing the accuracy of the measurement. .
