Description

An auxiliary device for topographical surveying

technical field

The utility model relates to the technical field of measurement auxiliary tools, in particular to a topographic measurement auxiliary device.

Background technique

In the early stage of national land space planning, there will be professional operators with equipment to carry out topographic survey, and topographic survey refers to the operation of surveying and drawing topographic maps, that is, the projected position and elevation of the objects and terrain on the earth's surface on the horizontal plane The work of making measurements, reducing them to a certain ratio, and drawing a topographic map with symbols and notes. The tools used include the tower ruler, which is a kind of leveling ruler. The single height measurement range is greatly improved, and the length is generally 5m. It can be shrunk when carrying it. Because its shape is similar to a tower, it is often called a tower ruler.

When the operator is doing terrain surveying work, most of them will use the combination of the leveling instrument and the tower ruler to measure, and this combination needs two people when using it, one is responsible for operating the leveling instrument, and the other is responsible for the specified location. Supporting the tower foot, since the tower foot has always been supported by manpower, the tower foot will shake to a certain extent with the support staff during the level observation process. In order to make the observed data more accurate and rigorous, now we need a topographic A device that assists the stability of the tower during measurement.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model.

As shown in Figure 1-2 and Figure 4, a topographic measurement auxiliary device includes a placement base 1 placed on the ground. Component 3, the plug-in component 3 includes a spherical seat 301 in the inner cavity of the placement seat 1, an adjustment rod 302 is fixedly installed around the outer surface of the spherical seat 301, and a rotating block 303 is installed on the end of the adjustment rod 302 away from the spherical seat 301 for rotation , the inner cavity of the rotating block 303 is threadedly equipped with a threaded rod 304, and one end of the threaded rod 304 near the top plate 2 is fixedly equipped with a movable ball head 305, and the outer surface of the movable ball head 305 is movably connected with the inner cavity of the top plate 2, and the movable ball head A twisting block 306 is fixedly installed on the outer surface of 305 away from the threaded rod 304. In some embodiments, the tower ruler is inserted into the inside of the spherical seat 301 through the opening at the center of the top plate 2 by placing the seat 1 at the measuring position of the tower ruler. , while keeping the vertical shape of the tower ruler through the spherical seat 301, it also replaces the situation that the operator needs to always support the tower ruler during the measurement process, which may cause the tower ruler to shake, that is, the stability of the tower ruler in the measurement work is guaranteed It also liberates the workload of the support staff, and at the same time ensures that the observation data is more rigorous and the data error is controllable. What needs to be explained is: the center of the top surface of the spherical seat 301 is provided with a groove that matches the outer surface of the tower ruler .

The working principle here: When the operator is performing measurement work, the level and the tower ruler need to be erected first, and when the staff operates the tower ruler, first place the placement seat 1 at the placement position of the tower ruler, and then place the The bottom end of the tower ruler is inserted into the groove of the spherical seat 301, and the tower ruler is maintained in a vertical working state through the groove of the spherical seat 301. However, during the measurement process, the measurement position is not smooth enough, and a certain slope will appear. This is the operator just needs to rotate the twisting block 306, the twisting block 306 drives the threaded rod 304 to rotate through the movable ball head 305, and the rotating threaded rod 304 makes the rotating block 303 at the adjustment place close to the threaded thread of the rotating block 303 inner wall Or away from the movement of the top plate 2, the moving rotating block 303 drives the spherical seat 301 to deflect through the adjusting rod 302, thereby adjusting the groove surface provided by the spherical seat 301, so that the tower ruler after insertion is kept vertical as far as possible, and the tower ruler is avoided from tilting. Problems affecting observed data.
