Description

A leveling height measuring device for wall control points

technical field

The utility model relates to the technical field of measuring tools, in particular to a leveling height measuring device for wall control points.

Background technique

In the construction survey of large-scale projects, it is necessary to lay out a three-dimensional precision control network in space. The control network is used as the benchmark for equipment installation, adjustment and monitoring. The leveling instrument and leveling rod are used for leveling measurement. The leveling rod is long and the ruler is There is a scale carved on the surface, and the bottom of the ruler is a plane, which is the reference starting plane of the scale. In order to measure the height difference between the two points A and B, the level is set up in the middle of the two points A and B to be measured, and then a leveling rod is placed on point A, and the leveling rod is aimed at the leveling rod reading ha on point A, and then the leveling rod is moved to To point B, the level gauge reading hb at point B. When placing a leveling rod on the point to be measured, a hemisphere with the same diameter as the sphere of the laser tracker needs to be placed on the target base of the point to be measured, and then the leveling rod is placed on the hemisphere so that the lower plane of the leveling rod and the upper surface of the hemisphere The plane is flat, so the height difference hb-ha of the two points measured by the level is the height difference between point A and point B.

Using a level to observe the height difference between two points on the ground is very common and easy to implement, but when observing the height difference between two points on the wall and the ground or the height difference between points on the wall, the leveling rod is used in the prior art. Put it vertically on the target base at the point on the wall, and it is very difficult to hold the leveling rod to keep it stable during the observation process. When the measurement point is high, people need to step on the ladder to hold the ruler. The measurement is very inconvenient, and the level must be erected at a very high height, but the height of the tripod on which the level is generally installed is about 1.5-2.0 meters. Therefore, in order to facilitate the erection of the level and personnel observation, the general erection height of the level is 1.5-2.0 meters Left and right, if the target height on the wall exceeds 2 meters, the line of sight of the level will not be able to see the scale on the leveling rod at the point on the wall, so it cannot be measured.

In addition, in the prior art, after the target seat is installed on the wall, the axis of the ball socket is parallel to the wall, and the sphere is installed in the ball socket. In this way, the sphere installed on the target seat can measure the higher point to be measured. The sphere is installed higher, and the tracker cannot see the sphere if it is lower than the target base, so it cannot be measured. At the same time, because the target base protrudes from the wall, it is easy to collide with other objects in actual work, which is inconvenient.
