Description

A Vertical Line Accuracy Test Device Convenient for Leveling

technical field

The utility model relates to a test device, in particular to a vertical line accuracy test device which is convenient for leveling, and belongs to the technical field of mechanical design and manufacture.

Background technique

The vertical line is an important device for monitoring the horizontal deformation of the dam and the resistance body, which is divided into a normal vertical line and an inverted vertical line. The upper end of the line body of the vertical line is fixed on the dam body, and the lower end is hung with a weight to make it tense; the lower end of the line body of the inverted perpendicular line is fixed on the bedrock, and the upper end is fixed on the buoy to make it tensioned. By installing a telemetry coordinate instrument around the vertical line body, the radial and tangential displacements of the vertical line in two horizontal directions can be automatically collected, thereby reflecting the horizontal deformation of the dam and the resistance body. In order to check the accuracy of the vertical line data, it is necessary to manually test the accuracy of the vertical line equipment periodically. The accuracy testing device currently used is a step-type vertical line calibration device. When using it, the bracket of the step-type vertical line calibration device is fixed on the vertical line cover, and the vertical line body is manually moved to make the line body stuck in the stepped line. In the stepped groove of the vertical line calibration device, the automatic system is used to collect the displacement of the vertical line in both tangential and radial directions, and then the accuracy of the automatically collected data can be verified by combining the groove data. Since the step-type vertical setting device cannot be accurately leveled independently, it needs manual use of pads to continuously try to determine whether it is level. The horizontal calibration rate is low, and it is difficult to meet the actual needs. Therefore it is necessary to improve the prior art.

The base is set as a flat plate with a plurality of screw holes, and bolts are arranged in the screw holes, so that the base can be fixed on the position to be measured by the bolts.

The adjusting rod includes a vertical screw rod arranged on the top surface of the base, and a sleeve sleeved on the vertical screw rod, wherein: the inner wall of the sleeve is provided with threads screwed with the vertical screw rod, and the top and bottom of the sleeve are They are respectively set to be open, and the top opening of the sleeve is socketed with the bearing with seat on the bottom of the plate, and the bottom of the sleeve is open and set on the vertical screw so that the sleeve, the bearing with seat, and the plate can be rotated. Rising or descending along the vertical screw can realize the height and low adjustment of the plate, and then meet the rapid adjustment of the level of the plate.

The base is set as a triangular flat plate, the size of which is smaller than that of the flat plate, so as to facilitate fixing and simultaneously facilitate the accuracy test operation of the vertical line.

There are three adjusting rods, which are arranged in an equilateral triangle between the flat panel and the base, so as to accurately level the flat panel.

Triangular and polygonal through holes are set on the flat plate to form a hollow flat plate, which is convenient for carrying and operation, and reduces weight at the same time.

The level is a conventional bubble level, which is set at the center of the top surface of the flat plate, so that the state of the level can be clearly observed during adjustment, and the level of the flat plate can be adjusted in time and accurately to meet the vertical line accuracy test requirements.

The utility model has the following advantages and effects: adopting the above scheme, the base can be conveniently fixed at the position to be measured, and the adjustment rod can be manipulated to coordinate with the spirit level to adjust the level of the plate. The whole adjustment process is fast, accurate, efficient and simple , greatly improving the efficiency of the vertical line accuracy test, reducing the difficulty of adjustment, and improving the accuracy of the vertical line accuracy test. It is an ideal vertical line accuracy test device.
