Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering detection, in particular to a tower ruler auxiliary device for height measurement. Background Art

[0002] Height measurement is the measurement work of determining the elevation of ground points. It uses a horizontal line of sight and a ruler erected on the ground to measure the height difference between two points on the ground. The elevation of one point is then used to calculate the elevation of the other point. It is mainly used in the establishment of the national leveling network.

[0003] In elevation measurement, the tower ruler is a commonly used measuring tool. The tower ruler is a kind of level ruler and is a used ruler. It is made of high-quality materials such as fiberglass, aluminum alloy, etc. During the use of the tower ruler, the tower ruler needs to be kept horizontal.

[0004] The prior art patent document CN212806997U provides a tower ruler auxiliary device for elevation measurement, which is equipped with a retractable rod with a built-in level bubble to achieve rapid leveling of the tower ruler, so that the test process is not affected by wind and tower tilt. It is safe, reliable, easy to carry and highly maneuverable.

[0005] Although the above-mentioned prior art is provided with a spirit level to facilitate leveling the scale, the position of the scale is fixed during use. When different angles need to be measured, the scale needs to be rotated together with the telescopic rod, and then re-leveled after rotation. The operation is relatively cumbersome, and the scale cannot be rotated well, which cannot meet people's needs. Therefore, we need a scale auxiliary device for height measurement.

Put the tower ruler body 11 between the two clamping blocks 10 in the through slot 5 of the rotating seat 2, and adjust the height of the device by the handle The screw rod 8 is rotated to make the moving block 9 move more stably in the slide groove 6, and the moving block 9 drives the clamping block 10 to move, and the clamping block 10 moves to clamp and fix the scale body 11. The level body 12 on the top of the rotating seat 2 is observed, and the adjustment device is used to make the scale body 11 in a horizontal state, completing the fixation and leveling of the scale body 11; when the scale body 11 needs to be rotated, the operator manually rotates the rotating seat 2, and the rotating seat 2 drives the annular block 302 to rotate, and the annular block 302 drives the annular plate 303 to rotate more stably in the annular groove 301. After rotating to the required position, the operator rotates the adjusting bolt 307 to make its end tightly against the annular block 302 to ensure that the scale body 11 will not rotate accidentally during the measurement process. This completes all the work. The content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field.
