The top of the electric lifting frame 2 is provided with a first rotating track 4 and a second rotating track 5, which are concentrically arranged. Figure 1As shown, the first rotating track 4 and the second rotating track 5 are arranged in a C-shape. An adjustment component 6 is slidably connected between the first rotating track 4 and the second rotating track 5. The adjustment component 6 includes an adjustment plate 601, and an adjustment track 602 is fixedly connected to the bottom of the adjustment plate 601. The adjustment track 602 is slidably connected to the opening of the first rotating track 4 and the second rotating track 5. The adjustment track 602 is a straight track. The first rotating track 4 and the second rotating track 5 are concentrically arranged, but their radii are different and their circumferences are different. When connected to the adjustment track 602... Minor errors are permissible during connection. A rotating seat 603 is provided below the adjusting track 602. A three-dimensional laser scanner 7 is fixedly installed at the bottom of the rotating seat 603. A spring 604 is fixedly connected to the top of the adjusting plate 601. A C-shaped limiting plate 605 is fixedly connected to the top of the spring 604. The two ends of the C-shaped limiting plate 605 slide from top to bottom through the opening inside the adjusting plate 601. A T-shaped limiting rod 606 is fixedly connected to the top of the C-shaped limiting plate 605. The C-shaped limiting plate 605 limits the rotating seat 603 when it descends to prevent it from falling.
[0016] To enable the 3D laser scanner 7 to switch between the first rotating track 4 and the second rotating track 5, this application further includes two first sliding grooves 401 fixedly connected to the top of the opening of the first rotating track 4. The two first sliding grooves 401 are symmetrically arranged. An adjusting plate 601 is slidably disposed inside the first sliding groove 401. A first guide member 402 is fixedly connected to the top of the first sliding groove 401. The bottom of a T-shaped limiting rod 606 is slidably connected to the top of the first guide member 402. The top of the first guide member 402 has a first limiting groove 403 adapted to the T-shaped limiting rod 606. When the T-shaped limiting rod 606 moves into the first limiting groove 403, the adjusting track 602 is aligned and limited by the elastic action of the spring 604. Two second slide grooves 501 are fixedly connected to the top of the opening of the moving track 5. The two second slide grooves 501 are symmetrically arranged. The adjusting plate 601 is slidably disposed inside the second slide groove 501. A second guide member 502 is fixedly connected to the top of the second slide groove 501. The bottom of the T-shaped limiting rod 606 is slidably connected to the top of the second guide member 502. The top of the second guide member 502 has a second limiting groove 503 adapted to the T-shaped limiting rod 606. When the T-shaped limiting rod 606 moves into the second limiting groove 503, the adjusting track 602 is aligned and limited under the elastic action of the spring 604. A C-shaped support plate 504 is fixedly connected to one side of the second guide member 502. The bottom of the C-shaped support plate 504 is movably connected to the top of the first slide groove 401.
[0017] To achieve the circular motion of the 3D laser scanner 7, this application further includes a plurality of rotating wheels 6031 rotatably connected to the inner side of the rotating base 603, and a limiting wheel 6032 rotatably connected to the base plate of the rotating base 603. The limiting wheel 6032 and the rotating wheel 6031 are set on both sides of the vertical plate of the adjusting track 602. A servo motor 6033 is fixedly installed on the outer side of the rotating base 603. The output end of the servo motor 6033 is fixedly connected to one end of one of the rotating wheels 6031. The servo motor 6033 rotates and drives the rotating wheel 6031 to rotate, thereby driving the rotating base 603 to perform circular motion along the second rotating track 5, thereby scanning the object.
[0018] To facilitate the opening of the second rotating track 5 and the pulling of the adjustment plate 601, this application also includes a fixed frame 8 fixedly connected to the top of the electric lifting frame 2. The bottom of the two side arms of the fixed frame 8 are fixedly connected to the top of the first rotating track 4. The middle arm of the fixed frame 8 is rotatably connected to the second rotating track 5 via a hinge. This arrangement allows the second rotating track 5 to be opened, avoiding interference with the object to be scanned during height adjustment. The control panel 3 is fixedly installed on the outside of the base 1 by embedding. The top of the base 1 is provided with a scanning positioning area 9, which is located directly below the center of the first rotating track 4. One end of the adjustment plate 601 is provided with a handle 607. A telescopic rod 608 is provided inside the spring 604. One end of the telescopic rod 608 is fixedly connected to the top of the adjustment plate 601, and the other end of the telescopic rod 608 is fixedly connected to the bottom of the C-shaped limiting plate 605.
[0019] In use, first place the object to be scanned at the center of the scanning positioning area 9. Select a suitable rotating track based on the size of the object. When the 3D laser scanner 7 is located on the second rotating track 5, and no adjustment of the rotating track is needed based on the size of the object, then control the electric lifting frame 2 via the control panel 3 to adjust the height of the 3D laser scanner 7 according to actual usage requirements. Next, start the servo motor 6033. Because the output end of the servo motor 6033 is fixedly connected to the rotating wheel 6031, and the base plate of the rotating seat 603 is rotatably connected to the limit wheel 6032, which is located on both sides of the vertical plate of the adjustment track 602, the servo motor 6033 rotates and drives the rotating wheel 6031 to rotate, thereby causing the rotating seat 603 to move in a circular motion along the second rotating track 5 to scan the object. When the 3D laser scanner 7 is located on the second rotating track 5, and the rotating track needs adjustment based on the size of the object, pull the handle 607 to move the adjustment plate 6. 01 Slides inside the first slide groove 401 and the second slide groove 501. The T-shaped limiting rod 606 disengages from the second limiting groove 503 and moves downward along the inclined surface at the top of the second guide member 502. It passes through the top of the C-shaped support plate 504 and the inclined surface at the top of the first guide member 402 in sequence to reach the first limiting groove 403. At this time, the spring 604 is stretched. Under the elastic action of the spring 604, the adjusting track 602 is aligned and limited. During this process, the two ends of the C-shaped limiting plate (605) slide from top to bottom through the opening inside the adjusting plate (601). The hole descends into the inner cavity of the adjustment track 602 and limits the rotation wheel 6031 to prevent it from falling out of the adjustment track 602 during the switching process. At this time, the adjustment plate 601 disengages from the second slide groove 501. Because the middle support arm of the fixed frame 8 is rotatably connected to the second rotating track 5 through a hinge, the second rotating track 5 can be flipped open to avoid interference with the object to be scanned during height adjustment. The servo motor 6033 is then started to drive the rotating seat 603 to make circular motion along the first rotating track 4, thereby scanning the object.
