Description

A vertical line accuracy test device for easy leveling

technical field

The invention relates to a test device, in particular to a vertical line accuracy test device that 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, and it is divided into a positive vertical line and an inverted vertical line. The upper end of the line body of the positive vertical line is fixed on the dam body, and the lower end of the line body is hung with a heavy hammer to tighten it; the lower end of the line body of the inverted vertical line is fixed on the bedrock, and the upper end is fixed on the buoy to tighten it. By installing a telemetry coordinate instrument around the vertical line body, the displacements in the two horizontal directions of the vertical line radial and tangential 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 on a regular basis. The accuracy test device currently used is a stepped vertical line calibration device. When using, first fix the bracket of the stepped vertical line calibration device on the vertical line cover, and manually move the vertical line body to make the line body stuck in the stepped vertical line. In the stepped groove of the vertical line calibrating device, the automatic system is used to collect the displacement of the vertical line in the tangential and radial directions, and then the accuracy of the automatically collected data can be checked by combining the groove data. Since the step-type vertical alignment device cannot be leveled accurately and autonomously, it is necessary to manually use the 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 existing technology.

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 a thread that is screwed with the vertical screw rod, and the top and bottom of the sleeve are They are respectively set as open, and the top opening of the sleeve is sleeved with the bearing with seat set on the bottom surface of the plate, and the bottom opening of the sleeve is sleeved on the vertical screw, so that the sleeve, the bearing with seat and the plate can be rotated by rotating the sleeve. Up or down along the vertical screw can realize the height and low adjustment of the plate, thereby satisfying the rapid adjustment of the levelness 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 be convenient for fixing, and at the same time, it is convenient for the accuracy test operation of the vertical line.

There are three adjusting rods, which are arranged in a regular triangle between the flat plate and the base, so that the flat plate can be leveled accurately.

Triangular and polygonal through holes are arranged on the flat plate to form a hollow flat plate, so as to facilitate carrying and operation, and at the same time reduce the weight.

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

The present invention has the following advantages and effects: by adopting the above scheme, the base can be conveniently fixed at the position to be measured, and the adjustment rod can be manipulated and cooperated with the level to adjust the level of the flat plate, and the whole adjustment process is fast, accurate, efficient and simple, It greatly improves the efficiency of the vertical line accuracy test, reduces the difficulty of adjustment, and improves the accuracy of the vertical line accuracy test. It is an ideal vertical line accuracy test device.
