Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to an axis measurement horizontal calibration system. Background Art

[0002] Axis measuring devices are devices that measure the position, height, angle and other information of an object through instruments. Common ones include theodolites, total stations and distance meters. In order to ensure accurate measurement results, it is often required to keep the measuring components in a horizontal position.

[0003] The preparation work before the inspection of the existing axis measurement equipment is: set three supporting legs at the lower end of the placement frame, first turn out the supporting legs, place them on the ground to be inspected and keep them fixed, then loosen the locking bolts on the supporting legs, and adjust the telescopic supporting legs to make the placement frame roughly horizontal, then tighten the locking bolts to fix the adjustment result, and finally adjust the adjusting bolts on the placement frame to make the placement frame accurately horizontal.

[0004] Although this allows the measuring assembly to be placed horizontally, there are still the following disadvantages: In order to achieve horizontal placement of the placement frame, the worker must adjust the extension length of the three support legs and lock them with the locking bolts. By observing whether the measuring assembly is level, if the difference is too large, the operator must loosen the locking bolts and readjust. After loosening the locking bolts, the extension length of the support legs is prone to change. The operator needs to fix it by hand in advance and then fix it with the locking bolts. In the process, the support rod may slip, resulting in low accuracy of the adjustment result, so that multiple adjustment operations may be required, and the adjustment operation is relatively cumbersome.

The adjustment structure is arranged on the placement frame 4, and is used to adjust the horizontality of the placement frame 4.

[0029] The axis measurement horizontal calibration system of this embodiment mainly includes a hardware system and a software system, and this embodiment shows the hardware system.

[0030] The placement rack 4 in this embodiment includes a first connection layer 41 and a second connection layer 42. The first connection layer 41 is rotatably connected to the support stand, and the second connection layer 42 is connected to the measuring component 1. A gap is provided between the first connection layer 41 and the second connection layer 42, the threaded rod 43 is fixedly connected to the first connection layer 41, and the threaded rod 43 is rotatably connected to the second connection layer 42.
