Description

Technical Field

[0001] This utility model belongs to the field of scanner bracket technology, specifically relating to a cantilever scanner bracket device. Background Technology

[0002] Building 3D scanners, through non-contact measurement technology, can assist in tasks such as high-precision terrain data acquisition, high-precision digital model generation, and structural safety assessment.

[0003] In current technology, scanners are typically mounted on top of a horizontal tripod. However, during actual measurements, situations often arise where the distance between adjacent targets is small or the ground conditions between them are poor. In such cases, the tripod cannot be properly positioned between two adjacent targets and must be mounted on opposite sides of them. This creates a blind spot between the two targets that cannot be scanned (as shown in the attached image). Figure 1 As shown in the image, insufficient data acquisition during scanning affects the data acquisition effect. To solve the above problem, a cantilever scanner support device is needed. Utility Model Content

[0004] The present invention aims to provide a cantilever scanner support device to facilitate scanning of adjacent targets with small spacing and reduce scanning blind spots.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cantilever scanner support device includes a tripod, a turntable, and a movable base. A level is fixedly mounted on the top of the tripod. The turntable is rotatably mounted on the top of the tripod, and a fixed base is mounted on the top of the turntable. A first telescopic rod assembly and a second telescopic rod assembly are rotatably connected to the fixed base. The side walls of the movable base are rotatably connected to the ends of the first telescopic rod assembly and the second telescopic rod assembly, respectively. A mounting platform is fixedly mounted on the top of the movable base. The fixed base, the first telescopic rod assembly, the second telescopic rod assembly, and the movable base form a parallelogram structure. The first telescopic rod assembly is connected to the turntable via an angle adjustment assembly.

[0007] The principle and effects of this technical solution:

[0008] In use, first, set up the tripod on the opposite sides of two adjacent targets to be scanned and adjust it to be in a horizontal position. At this time, the fixed base is in a vertical position. Since the fixed base, the first telescopic rod assembly, the second telescopic rod assembly, and the movable base form a parallelogram structure, the movable base is also in a vertical position. Then, install the scanner body on the mounting platform on top of the movable base, press down on the end of the first telescopic rod assembly away from the movable base, and lift the movable base using the lever principle. Then, rotate the turntable to move the horizontal position of the movable base between the two adjacent targets to be scanned. Then, use the angle adjustment component to limit the first telescopic rod assembly so that the angle between the first telescopic rod assembly and the horizontal plane remains constant.

[0009] By arranging the fixed base, the first telescopic rod assembly, the second telescopic rod assembly, and the movable base into a parallelogram structure, the movable base can be kept vertical when the fixed base is adjusted to a vertical position, improving the accuracy of the scanning results. By rotatably connecting the first telescopic rod assembly to the fixed base, the scanner body can be placed between two adjacent targets when the tripod is set up on opposite sides of the targets to be scanned, thus facilitating the scanning of adjacent targets with small spacing and reducing the scanning blind zone.

[0010] In this utility model, the turntable is provided with a connecting seat on its side wall, the first telescopic rod assembly is provided with a mounting frame, and the angle adjustment assembly includes a rotating shaft that rotatably passes through the mounting frame and a rope wound around the rotating shaft. One end of the rope is connected to the radial outer side wall of the rotating shaft, and the other end of the rope is connected to the connecting seat.

[0011] In this invention, the angle adjustment assembly further includes a ratchet fixedly sleeved on the radial outer side wall of the rotating shaft on the outside of the mounting bracket, and a pawl rotatably disposed on the outer side wall of the mounting bracket and cooperating with the ratchet.

[0012] The principle and effects of this technical solution:

[0013] When the movable seat needs to be raised, the shaft is rotated clockwise to wind up the rope. The rope pulls the end of the first telescopic rod assembly away from the movable seat downwards, thereby raising the movable seat upwards through the lever principle. When the ratchet rotates clockwise with the shaft, it can push the pawl to rotate. After the movable seat is raised to the appropriate position, the shaft is released. Under the action of gravity, the movable seat tends to move downwards. At this time, the pawl prevents the ratchet from rotating counterclockwise, thereby preventing the shaft from rotating counterclockwise.

[0014] With the above settings, the distance between the connecting seat and the mounting frame can be adjusted by rotating the shaft to wind up the rope, thereby achieving the purpose of rotating the first telescopic rod assembly; by setting a ratchet and pawl that cooperate with each other, the first telescopic rod assembly can be limited after being rotated to an appropriate position, so as to keep the angle between the first telescopic rod assembly and the horizontal plane constant.

[0015] In this invention, the tripod includes a vertically arranged chisel, with a movable rod slidably inserted at the top of the chisel. A first threaded hole is formed transversely on the inner wall of the chisel. After the movable rod is slid up and down to a suitable position, a fastening bolt is threaded into the first threaded hole, and the end of the fastening bolt abuts against the outer wall of the movable rod. This design allows workers to easily adjust the installation height of the fixed base according to actual conditions, further improving the applicability of the device.

[0016] In this invention, a fixed shaft is provided at the top of the movable rod along its axial direction, and the bottom of the turntable is rotatably sleeved on the fixed shaft. A through second threaded hole is provided on the inner sidewall of the turntable. With this arrangement, after rotating the turntable to move the movable seat to a suitable position, the fastening bolt is threaded through the second threaded hole, and its end abuts against the sidewall of the fixed shaft. This prevents the turntable from rotating during scanner operation, improving the accuracy of the scanning results.

[0017] In this invention, the bottom of the turntable is provided with a lower edge that slides and abuts against the bottom of the fixed shaft. This design prevents the turntable from detaching from the fixed shaft, improving the safety of the device during use.

[0018] In this invention, the first telescopic rod assembly includes a first sleeve and a first insert rod. The first sleeve is rotatably connected to the fixed base. One end of the first insert rod is slidably inserted into the first sleeve, and the other end is rotatably connected to the radial outer wall of the movable base. The second telescopic rod assembly includes a second sleeve and a second insert rod. The second sleeve is rotatably connected to the fixed base. One end of the second insert rod is slidably inserted into the second sleeve, and the other end is rotatably connected to the radial outer wall of the movable base. The ends of the first and second sleeves are respectively provided with through-hole third screw holes. The side walls of both the first and second insert rods are provided with multiple insertion holes spaced apart. Through these features, the overall length of the first and second telescopic rod assemblies can be adjusted, further improving the applicability of this device.

[0019] In this invention, a hook is provided at the end of the first sleeve away from the first insert rod. This design allows a counterweight to be hung on the hook, preventing the device from tipping over during use and further improving its safety. Attached Figure Description

[0028] Example:

[0029] As attached Figure 2-6 As shown, this utility model discloses a cantilever scanner support device, including a tripod 10, a turntable 20, and a movable seat 50.

One torsion arm of the torsion spring is connected to the pawl 64, and the other torsion arm of the torsion spring is connected to the mounting bracket 33. The pawl 64 can be held in the position of being engaged with the ratchet 63 by the elastic force of the torsion spring. A lever is also fixedly disposed on the side of the pawl 64 away from the mounting bracket 33.

[0032] In this embodiment, the tripod 10 includes a vertically arranged chisel 11, a movable rod 12 is slidably inserted into the top of the chisel 11, and a through first screw hole 111 is opened on the inner side wall of the chisel 11 in the transverse direction.

[0033] In this embodiment, a fixed shaft 13 is provided at the top of the movable rod 12 along its axial direction, the bottom of the turntable 20 is rotatably sleeved on the fixed shaft 13, and a through second screw hole 23 is provided on the inner sidewall of the turntable 20 along the transverse direction.

[0034] In this embodiment, the bottom of the turntable 20 is provided with a lower edge that slides against the bottom of the fixed shaft 13.

[0035] In this embodiment, the first telescopic rod assembly 30 includes a first rod sleeve 31 and a first insert rod 32. The first rod sleeve 31 is rotatably connected to the fixed base 21. One end of the first insert rod 32 is slidably inserted into the first rod sleeve 31, and the other end of the first insert rod 32 is rotatably connected to the radial outer wall of the movable base 50. The second telescopic rod assembly 40 includes a second rod sleeve 41 and a second insert rod 42. The second rod sleeve 41 is rotatably connected to the fixed base 21. One end of the second insert rod 42 is slidably inserted into the second rod sleeve 41, and the other end of the second insert rod 42 is rotatably connected to the radial outer wall of the movable base 50. The ends of the first rod sleeve 31 and the second rod sleeve 41 are respectively provided with through third screw holes 71. The side walls of the first insert rod 32 and the second insert rod 42 are provided with multiple insertion holes 72 at intervals. The spacing between adjacent insertion holes 72 on the first insert rod 32 and the second insert rod 42 is the same.

[0036] In this embodiment, a hook 34 is provided at the end of the first rod sleeve 31 away from the first insertion rod 32.

[0037] The specific implementation process is as follows:

[0038] In use, first, set up the tripod 10 on the opposite sides of two adjacent targets to be scanned and adjust it to be in a horizontal state. At this time, the fixed base 21 is in a vertical state. Since the fixed base 21, the first telescopic rod assembly 30, the second telescopic rod assembly 40 and the movable base 50 form a parallelogram structure, the movable base 50 is also in a vertical state. Then, after installing the scanner body on the mounting platform 51 on the top of the movable base 50, press down the end of the first telescopic rod assembly 30 away from the movable base 50 and lift the movable base 50 using the lever principle. Then, rotate the turntable 20 to move the horizontal position of the movable base 50 between the two adjacent targets to be scanned. Then, use the angle adjustment assembly 60 to limit the first telescopic rod assembly 30 so that the angle between the first telescopic rod assembly 30 and the horizontal plane remains constant.

[0039] When it is necessary to raise the movable seat 50, the rotating shaft 61 is rotated clockwise to wind up the rope 62. The rope 62 pulls the end of the first telescopic rod assembly 30 away from the movable seat 50 downward, thereby raising the movable seat 50 upward through the lever principle. When the ratchet 63 rotates clockwise with the rotating shaft 61, it can push the pawl 64 to rotate. After the movable seat 50 is raised to the appropriate position, the rotating shaft 61 is released. The movable seat 50 tends to move downward under the action of gravity. At this time, the pawl 64 prevents the ratchet 63 from rotating counterclockwise, thereby preventing the rotating shaft 61 from rotating counterclockwise.
