Description

Technical Field

[0001] This utility model belongs to the field of traffic engineering technology, and more specifically, it relates to a portable elevation control tool. Background Technology

[0002] When constructing bridges and roads in traffic engineering, it is necessary to measure and mark the height and distance of the construction area. Elevation control tools are required for testing and marking, such as total stations. The handle on the total station makes it easy for workers to carry. Workers carry the total station to the construction area and then use a tripod to support it for measurement and marking.

[0003] According to CN202010821880.4, this application relates to a total station, belonging to the field of surveying equipment. To address the problem that adjusting the level of a total station is currently inconvenient and may affect the accuracy of measurement results, the application includes a total station body and a support assembly for mounting the total station body. It also includes an adjustment assembly mounted on the support assembly for adjusting the level of the total station body, and a mounting assembly mounted on the adjustment assembly for fixing the total station body. The support assembly includes a support block and multiple legs mounted on the support block. The mounting assembly is equipped with a leveling instrument for detecting the level of the mounting block. This application allows for more convenient adjustment of the level of the total station body, reducing the impact of total station body tilt on measurement results.

The lenses and displays are located on the outside of the equipment and are exposed. When staff carry the total station, it is easily bumped or knocked. When the total station is bumped or knocked, it is easy to damage the lenses and displays. Utility Model Content
