Description

Technical Field

[0001] The present application relates to the technical field of surveying and mapping platforms, and more specifically, to an angle-adjustable surveying and mapping platform and a method for using the same. Background Art

[0002] When the surveying and mapping tools are used, they need to be placed on a surveying and mapping platform. Some surveying and mapping platforms are equipped with rollers for easy movement, which makes it troublesome to fix the rollers. When the surveying and mapping tools need to be moved at different angles, it is not convenient to adjust the angle of the surveying and mapping platform. In addition, although the existing surveying and mapping platforms use a pitch adjustment mechanism, a horizontal rotation mechanism and a bottom roller mechanism to achieve adjustments in different dimensions, a locking mechanism needs to be designed separately for each adjustment action, and different locking operations need to be performed independently at different times, which makes the entire operation cumbersome.

[0003] The document with the prior art publication number CN 115539771 A provides an angle-adjustable surveying and mapping platform and a method for using the same. When the device moves the surveying and mapping platform body, rollers are installed at the bottom of the base, so that the surveying and mapping platform body can be easily moved by the rollers. After the surveying and mapping platform body moves to a specified position, the angle of the surveying and mapping platform body needs to be adjusted. By rotating the surveying and mapping platform body, the surveying and mapping platform body can drive the fixed rod to rotate around the first rotating rod, thereby adjusting the angle of the surveying and mapping platform body.

[0004] Although the above-mentioned prior art solutions can achieve the relevant beneficial effects through the structure of the prior art, they still have the following defects: First, the device is relatively bulky as a whole, and the operation of use and storage is extremely inconvenient; second, the device is adjusted by unidirectional rotation of the surveying and mapping platform body, and the angle adjustment is single; third, when the surveying and mapping platform body is adjusted horizontally, there is a lack of corresponding calibration devices, so it is not convenient for leveling.

[0005] Regarding the above-mentioned related technologies, the inventor believes that when the terrain to be surveyed is more complex, the lightweight equipment is not only conducive to the carrying of personnel, but also can reduce the weight. At the same time, the angle adjustment of the current surveying and mapping platform is mostly adjusted by three base foot screws. Therefore, the three base foot screws need to be adjusted up and down during each adjustment process, and the adjustment process is relatively cumbersome.

[0006] In view of this, we propose an angle-adjustable surveying and mapping platform and a method for using the same. Summary of the invention
