[0002] Three-dimensional measurement, as the name implies, is to measure the object in all directions and determine the three-dimensional coordinate measurement data of the object. Its measurement principle is divided into four aspects: ranging, angular displacement, scanning, and orientation.

[0003] At present, three-dimensional measurement is widely used in construction engineering, and total stations are usually used to measure spatial geometric dimensions, spatial areas, and spatial volumes. In the process of three-dimensional measurement, it is usually necessary to adjust the position of the total station, and scan by moving the total station to different coordinate positions to achieve the purpose of obtaining more accurate scanning data.

[0004] However, the total station currently used in construction sites is usually mounted on a tripod, and the height of each support leg is adjusted individually according to the corresponding height requirements, so that the total station can reach the corresponding height requirements. However, when the total station needs to be moved, if the tripod is not folded and stored, the terrain conditions at the construction site are relatively complex, which will make it inconvenient to move the total station.

[0044] Reference Figure 1 and Figure 3When the total station 2 needs to be carried, the pull ring 631 is pushed downward, so that the pull ring 631 drives the upper positioning sleeve 611 to move downward through the push rod 632 and compresses the upper return spring 613, and drives the positioning column 614 to move downward, so that the positioning column 614 slides along the arc surface between the annular groove 521 and the peripheral side wall of the connecting rod 52 to the side wall of the connecting rod 52, thereby separating from the annular groove 521 on the connecting rod 52, thereby releasing the lock of the connecting rod 52, and allowing the positioning column 614 to move downward to the retreat slope, and The positioning column 614 is made to slide along the retreat slope, so that the positioning column 614 compresses the positioning spring 615, and the end of the positioning column 614 slides along the retreat slope to the peripheral side wall of the fixing sleeve 612, thereby being completely separated from the connecting rod 52, so that the connecting rod 52 can be pushed away from the mounting plate 11 by the thrust spring 616, so that the connecting rod 52 pulls the support rod 51 to rotate downward, thereby pulling the pillar 12 through the support rod 51, thereby realizing the automatic closing of the three pillars 12, thereby facilitating the folding of the bracket 1.

[0045] Reference Figure 3 and Figure 4 When the pull ring 631 drives the push rod 632 to move downward, the push rod 632 presses the top block 633, so that the top block 633 drives the locking sleeve 622 to move downward and stretches the lower spring 634 through the limit block, so that the guiding inclined surface at the upper end of the unlocking groove 6221 on the locking sleeve 622 contacts the top wall of the end of the locking hook 621 outside the extension rod 41, thereby pressing the locking hook 621 downward, so that the locking hook 621 is disengaged from the slot 121 on the pillar 12 and twists the locking torsion spring 623, thereby releasing the locking hook 621 from the locking of the pillar 12, and the end of the locking hook 621 is locked. The upper portion slides along the guide inclined surface to the inner wall of the locking sleeve 622, and then the pull ring 631 is released, so that the extension rod 41 is retracted into the pillar 12 under the action of the push spring 635, and the locking sleeve 622 is reset upward under the action of the lower spring 634, so that the locking sleeve 622 and the locking hook 621 move synchronously toward the direction of the mounting plate 11, so that the locking hook 621 passes over a plurality of slots 121 until the extension rod 41 is gradually retracted into the pillar 12, thereby realizing the automatic retraction of the extension rods 41 on the three pillars 12, thereby completing the folding of the bracket 1, so as to facilitate the transfer of the total station 2.

[0046] The working principle of the embodiment of the present application is as follows: by opening the pillar 12, the connecting rod 52 is inserted into the fixing sleeve 612, the connecting rod 52 is positioned by the positioning member, and the pillar 12 is supported by the supporting rod 51, so as to facilitate maintaining the stability of the pillar 12 supporting the mounting plate 11. Then, the extension length of the extension rod 41 is appropriately adjusted according to the terrain, and the extension rod 41 is limited by the engagement of the locking hook 621 with the card slot 121, and finally, the angle of the total station 2 is adjusted by the leveling mechanism 3, and then the coordinates or buildings on the construction site are scanned and measured by the total station 2.

[0047] When the total station 2 needs to be transported, the pull ring 631 is pressed down to drive the upper positioning sleeve 611 to move, so that the positioning piece releases the lock on the connecting rod 52, so that the pillar 12 can be folded, and at the same time, the push plate presses down the top block 633, so that the locking sleeve 622 drives the locking hook 621 to separate from the pillar 12, so that the extension rod 41 can be retracted into the pillar 12 under the action of the push spring 635, thereby facilitating the rapid folding of the bracket 1 and the convenience of transporting the total station 2.

[0048] The present application also discloses a three-dimensional measurement method, comprising the following steps: The support frame 1 is propped up, and the support columns 12 are spread out, so that the support structure 5 supports the support columns 12 , and the support columns 12 support the mounting plate 11 , thereby supporting the total station 2 .

[0049] Adjust the total station 2 by extending the extension rod 41 out of the support column 12 according to the terrain conditions, thereby adjusting the height of the total station 2, and adjusting the angle of the total station 2 through the leveling assembly.

[0050] Scanning measurement uses the adjusted total station 2 to scan and measure the coordinates in the building scene and the building environment.

[0051] When carrying the total station 2 , the support 1 is quickly folded by the folding mechanism 6 , and the support 1 is carried to the next point according to the location requirements, so as to facilitate the continued scanning work of the total station 2 .

[0052] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
