Description

A New Measuring Base

technical field

The utility model belongs to the field of engineering measurement, in particular to a novel measuring base.

Background technique

The base is an auxiliary tool commonly used in the field of engineering surveying. Its main function is to provide a stable base for centering and leveling various measuring equipment or accessories such as prisms, GNSS receivers, and total stations in various complex measurement environments. platform.

The base is usually composed of a central connector and a base, and there is an optical plummet inside the central connector, which requires the human eye to observe the alignment of the ground mark through the side eyepiece. When the height of the base is too high or too low, it will bring inconvenience to the observation and alignment. Therefore, the height of the instrument is often determined by the height of the operator rather than the needs of the observation. At the same time, the current method of measuring the height of the instrument is to measure the slope height from the center point of the ground mark to a certain mark on the instrument with the help of a tape measure after leveling. The error of the instrument height obtained in this way is relatively large, which especially affects the accuracy of height measurement.

In addition, the height of the existing base cannot be adjusted after being centered and leveled. To adjust the height, it has to be re-centered and leveled, which greatly affects the efficiency of the measurement work.

Further, the laser distance measuring device includes a housing with a center line engraved on the side, a laser distance measuring module located inside the housing, a switch button connected to the laser distance measuring module for controlling the switch of the laser distance measuring module, and a laser distance measuring module. The ranging module is connected with a display screen for displaying ranging data, and a power module for providing electric energy for the laser ranging module.

Further, the diameter of the secondary telescopic rod is smaller than the diameter of the primary telescopic rod, and the diameter of the primary telescopic rod is smaller than the diameter of the connector pillar,

Further, scales are engraved on the secondary telescopic rod and the primary telescopic rod.

Further, the connector support is welded to the upper surface of the connector base plate.

Further, the power module is a battery or a charging head.

Further, the number of base screw is 3.

The utility model has the following advantages: the utility model has reasonable structure, convenient use, simple operation and strong practicability. The new measurement base has a laser distance measuring device, which can not only quickly center the laser spot, but also accurately measure the height of the instrument; two telescopic rods are installed on the support of the base connector, and the ring fastening button can be used to Freely adjust the height of the prism. When the instrument is set up for measurement, the prism is blocked and the appropriate height can be adjusted to continue observation, avoiding the need to re-set up the instrument to adjust the height of the instrument. There is a scale engraved on the telescopic rod. The scale value after stretching is the vertical distance from the center of the laser rangefinder to the top of the connector. The height obtained by the laser distance measuring device plus the scale value is the height of the instrument. The use of the device of the utility model not only brings convenience to the operation of the surveying and mapping personnel, but also greatly improves the efficiency of the surveying work.
