Description

Technical Field

[0001] This utility model relates to the field of 3D laser scanner technology, and in particular to a mobile fixture for a 3D laser scanner. Background Technology

[0002] As a major component of a 3D laser scanning system, a 3D laser scanner consists of a laser emitter, receiver, time counter, motor-controlled rotatable filter, control circuit board, microcomputer, CCD machine, and software. It represents a technological revolution in the surveying and mapping field after GPS technology. However, due to the large size of existing 3D laser scanners, they generally require corresponding moving fixtures for assistance during use.

[0003] For example, utility model patent application number 202321860887.2 discloses a mobile 3D laser scanner, including a base plate. Adjustment components are provided on both sides of the base plate, and a support cylinder is fixedly connected to the top of the base plate. Its beneficial effect is that, by setting the adjustment components and using a level, the mobile 3D laser scanner can adjust and support the structure, ensuring the horizontal stability of the structure under different terrains. By setting the clamping components, the scanner body can be clamped and installed, ensuring the stability of the scanner body during use.

[0004] Based on existing technology, most existing mobile fixtures for 3D laser scanners are single-function and lack automated rotation adjustment capabilities. This means that when the measurement orientation of the 3D laser scanner needs to be changed, the entire mobile fixture needs to be moved, which is inconvenient to use. Furthermore, the lack of automated tilt adjustment capabilities makes it difficult to adjust the measurement tilt angle of the 3D laser scanner, resulting in low practicality. Therefore, this utility model proposes a mobile fixture for 3D laser scanners to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to propose a mobile fixture for a 3D laser scanner, which solves the problems that existing mobile fixtures for 3D laser scanners lack automated rotation adjustment and tilt adjustment functions.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a mobile fixture for a 3D laser scanner, including a mobile base, a support shaft rotatably connected to the top of the mobile base by a rotation adjustment mechanism, a turntable fixed to the top of the support shaft, a support plate driven to rise and fall by a lifting adjustment mechanism above the turntable, a first hinge seat fixed to the top of the support plate, a first rotating plate driven to tilt by a tilt adjustment mechanism hinged to the inner side of the first hinge seat, a support platform fixed to the top of the first rotating plate, a 3D laser scanner body placed on the upper surface of the support platform, and a scanner limiting mechanism adapted to the 3D laser scanner body provided at the top of the support platform.

[0007] A further improvement is that the scanner limiting mechanism includes a bidirectional lead screw rotatably connected inside the support platform and driven to rotate by a throttle, and a threaded plate threadedly sleeved on both sides of the bidirectional lead screw. The top of the threaded plate slides through to the outside of the support platform and is fixed with a first clamping plate.

[0008] A further improvement is that: a second clamping plate is symmetrically provided on the side of the first clamping plate near the body of the 3D laser scanner, a support frame that is fixedly connected to the second clamping plate slides through the first clamping plate, a positioning bolt is threaded through the support frame, and a positioning block is connected to the end of the positioning bolt near the first clamping plate.

[0009] A further improvement is that the tilt adjustment mechanism includes a rotating shaft fixed to the lower part of the first rotating plate and rotatably connected to the inner side of the first hinge seat, and a cylinder fixed to the top of the support plate. The output end of the cylinder is fixed with a rack that is slidably connected to the support plate. The end of the rotating shaft near the rack passes through a bearing to the outside of the first hinge seat and is fixed with a gear adapted to the rack.

[0010] A further improvement is that: a second hinge seat is provided on both sides of the first hinge seat and fixed to the top of the support plate; a second rotating plate is hinged inside the second hinge seat; and the top of the second rotating plate is fixed to the bottom of the support platform.

[0011] A further improvement is that the lifting and adjusting mechanism includes a hydraulic cylinder fixed to the bottom of the turntable and a lifting plate fixed to the output end of the hydraulic cylinder. A lifting rod that slides through the top of the turntable is symmetrically fixed between the lifting plate and the support plate. A sliding rod that slides through the lifting plate is symmetrically fixed inside the turntable.

[0012] A further improvement is that the rotation adjustment mechanism includes a servo motor fixed to the top of the movable base and a driven sprocket fixed to the lower part of the support shaft. The output end of the servo motor passes through the movable base through a bearing and is fixed with a drive sprocket that is connected to the driven sprocket.

[0013] The beneficial effects of this utility model are as follows: This utility model includes a movable base, and a rotating adjustment mechanism drives the support shaft at the top of the movable base to rotate the turntable. During the rotation of the turntable, the support plate and support platform rotate synchronously, so that the measuring head of the 3D laser scanner body rotates to the corresponding position, thereby enabling the movable fixture to have an automated rotation adjustment function. Furthermore, a tilt adjustment mechanism drives the first rotating plate hinged to the inner side of the first hinge seat to rotate. During the rotation of the first rotating plate, the support platform tilts, so that the measuring head of the 3D laser scanner body tilts synchronously to the corresponding angle, thereby enabling the movable fixture to have an automated tilt adjustment function. It is convenient to use and has high practicality. Attached Figure Description

[0020] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0021] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, this embodiment provides a mobile fixture for a 3D laser scanner, including a mobile base 1 with casters at its four corners and a support shaft 2 rotatably connected to the middle of the top of the mobile base 1. A push-pull handle is fixed to the left side of the top of the mobile base 1 for easy user movement of the fixture. The support shaft 2 is driven and rotates via a rotation adjustment mechanism. A hollow turntable 3 is bolted to the top of the support shaft 2 and rotates synchronously with the support shaft 2. A support plate 4 is located above the turntable 3 and is driven and moved up and down via a lifting adjustment mechanism inside the turntable 3. A first hinge seat 5 is bolted to the middle of the top of the support plate 4. A first rotating plate 6 is hinged to the inner side of the first hinge seat 5 and is driven by a tilt adjustment mechanism to rotate around the hinge. The first rotating plate 6 is bolted to a hollow support platform 7. A 3D laser scanner body 8 for 3D measurement is placed on the upper surface of the support platform 7. The 3D laser scanner body 8 is limited and blocked at the top of the support platform 7 by a scanner limiting mechanism to prevent it from slipping off the support platform 7. The rotating adjustment mechanism drives the support shaft 2 at the top of the movable base 1 to drive the rotating platform 3 to rotate. During the rotation of the rotating platform 3, the support plate 4 and the support platform 7 rotate synchronously, so that the measuring head of the 3D laser scanner body 8 rotates to the corresponding position. The tilt adjustment mechanism drives the first rotating plate 6, which is hinged to the inner side of the first hinge seat 5, to rotate. During the rotation of the first rotating plate 6, the support platform 7 tilts, so that the measuring head of the 3D laser scanner body 8 tilts synchronously to the corresponding angle.

[0022] The scanner limiting mechanism includes a throttle 9, a bidirectional lead screw 10, and threaded plates 11. The bidirectional lead screw 10 is rotatably connected to the inside of the support platform 7 via a bearing. The right end of the bidirectional lead screw 10 passes through the support platform 7 via a bearing and is fixedly connected to the throttle 9 with bolts. There are two sets of threaded plates 11, which are threaded onto both sides of the bidirectional lead screw 10 with opposite threading directions. The top of the threaded plate 11 slides through the support platform 7 and is fixed with a first clamping plate 12 by bolts. The top of the support platform 7 has a through groove through which the threaded plate 11 slides. Anti-slip rubber pads are fixed on opposite sides of the two sets of first clamping plates 12. By rotating the throttle 9, the bidirectional lead screw 10 is driven to rotate, causing the threaded plates 11 threaded onto both sides of the bidirectional lead screw 10 to move towards each other. The threaded plates 11 then drive the first clamping plates 12 to move, forming a clamping and limiting mechanism on both sides of the 3D laser scanner body 8.

[0023] Each first clamping plate 12 has a second clamping plate 13 symmetrically distributed front and back on the side closest to the 3D laser scanner body 8. A support frame 14 corresponding to the position of the second clamping plate 13 is provided on the side of the first clamping plate 12 away from the 3D laser scanner body 8. The support frame 14 slides through the first clamping plate 12 and is fixedly connected to the second clamping plate 13 on the side closest to the first clamping plate 12. The portion of the support frame 14 in contact with the first clamping plate 12 has protrusions symmetrically distributed vertically. The inner side of the first clamping plate 12 has a sliding groove adapted to the support frame 14 and its protrusions for sliding. The protrusions are also designed to... To prevent the support frame 14 from falling off, a positioning bolt 15 is threaded through the side of the support frame 14 away from the first clamping plate 12. A positioning block 16 is connected to the end of the positioning bolt 15 near the first clamping plate 12. First, slide and adjust the second clamping plate 13 until it limits the front and rear sides of the 3D laser scanner body 8. Then, rotate the positioning bolt 15 towards the first clamping plate 12 until the positioning block 16 abuts against the first clamping plate 12, thus achieving the positioning of the second clamping plate 13 (the 3D laser scanner body 8 will not shake significantly, so only appropriate limiting is needed, and the first clamping plate 12 does not require excessive firmness).

[0024] The tilt adjustment mechanism includes a rotating shaft 17 and a cylinder 18. The rotating shaft 17 is fixed and passes through the lower part of the first rotating plate 6, and both ends of the rotating shaft 17 are rotatably connected to the inner side of the first hinge seat 5 through bearings. The cylinder 18 is fixed to the rear side of the top of the support plate 4 by bolts. A rack 19 is fixed to the output end of the cylinder 18, and a pulley is fixed to the bottom end of the rack 19. A sliding groove adapted to the pulley is opened at the top of the support plate 4 to realize the sliding connection between the rack 19 and the support plate 4. The end of the rotating shaft 17 near the rack 19 passes through the bearing to the outside of the first hinge seat 5 and is fixed with a gear 20. The gear 20 and the rack 19 mesh and fit together. The cylinder 18 drives the rack 19 at its output end to move. During the movement of the rack 19, the gear 20 is driven to rotate. The gear 20 then drives the first rotating plate 6 to rotate and tilt through the rotating shaft 17.

[0025] The first hinge seat 5 is provided with a second hinge seat 21 on both sides, and the second hinge seat 21 is fixed to the top of the support plate 4 by bolts. A second rotating plate 22 is hinged inside the second hinge seat 21, and the top of the second rotating plate 22 is fixed to the bottom of the support platform 7 by bolts.

[0026] The lifting and adjusting mechanism includes a hydraulic cylinder 23 and a lifting plate 24. The hydraulic cylinder 23 is fixed to the bottom of the turntable 3 by bolts. The lifting plate 24 is fixed to the output end of the hydraulic cylinder 23 by bolts. The top of the lifting plate 24 is symmetrically fixed with lifting rods 25, and the top of the lifting rods 25 slides through the top of the turntable 3 and is fixed to the bottom of the support plate 4. The turntable 3 is symmetrically fixed with sliding rods 26 that slide through the lifting plate 24, which limit the movement of the lifting plate 24. The lifting plate 24 at its output end is driven to move up and down by the hydraulic cylinder 23. The lifting plate 24 then drives the support plate 4 to move up and down synchronously by the lifting rods 25.

[0027] The rotation adjustment mechanism includes a servo motor 27 and a driven sprocket 28. The servo motor 27 is fixed to the right side of the top of the movable base 1 by bolts. The lower part of the support shaft 2 passes through the interior of the movable base 1 through a bearing. The driven sprocket 28 is fixedly sleeved on the lower part of the support shaft 2. The output end of the servo motor 27 passes through the interior of the movable base 1 through a bearing and is fixed with a drive sprocket 29. The drive sprocket 29 and the driven sprocket 28 are both sleeved with a chain and connected by chain drive. The servo motor 27 drives the drive sprocket 29 at its output end to rotate. The drive sprocket 29 drives the driven sprocket 28 to rotate through the chain. The driven sprocket 28 then drives the support shaft 2 to rotate synchronously.

[0028] When the 3D laser scanner is actually used with the mobile fixture, the 3D laser scanner body 8 is first placed on the upper surface of the support platform 7 and the scanner limiting mechanism is used to limit it so that the 3D laser scanner body 8 is not easy to slip off the support platform 7. Then the user moves the 3D laser scanner body 8 by pushing the mobile base 1.

[0029] When it is necessary to change the measurement orientation of the 3D laser scanner body 8, the rotation adjustment mechanism drives the support shaft 2 at the top of the moving base 1 to rotate the turntable 3. During the rotation of the turntable 3, the support plate 4 and the support platform 7 rotate synchronously until the measurement head of the 3D laser scanner body 8 at the top of the support platform 7 rotates to the corresponding orientation, thus completing the convenient change of the measurement orientation.

[0030] When it is necessary to change the measurement tilt angle of the 3D laser scanner body 8, the tilt adjustment mechanism drives the first rotating plate 6, which is hinged to the inner side of the first hinge seat 5, to rotate forward or backward. During the rotation of the first rotating plate 6, the support platform 7 is tilted forward and then backward, so that the measuring head of the 3D laser scanner body 8 at the top of the support platform 7 is tilted to the corresponding angle, thus completing the convenient change of the measurement tilt angle.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
