Abstract
Description
Technical Field
[0001] This utility model relates to the field of road inspection technology, specifically to a laser profiler support structure for road inspection. Background Technology
[0002] The laser profiler employs non-cooperative target laser ranging technology and precision angle measurement technology, closely integrating polar coordinate measurement methods with computer technology. It enables high-speed and accurate profile detection without post-processing, directly outputting reports. The profiler can be used for bridge static deflection detection, with high-precision angle control to ensure accurate measurement results. It also uses a dedicated controller to display results in a clear and intuitive manner. The laser ranging sensor does not require a reflecting prism. When using the laser profiler for road inspection, it is usually supported by a tripod.
[0003] However, the existing laser profiler support structure for road inspection still has some problems in use:
[0004] First, existing laser profiler supports are generally adjusted manually to change their height and angle. This manual adjustment is not precise enough and is cumbersome, which reduces the overall ease of use of the support structure.
[0005] Secondly, the legs of existing laser profilometer support structures can generally only be folded and retracted. Even after retraction, the legs still occupy a large amount of space, which makes the support structure inconvenient to carry. Utility Model Content
[0006] In order to solve the problems of inconvenient adjustment and carrying of existing support structures, the purpose of this utility model is to provide a support structure for a laser profiler for road detection.
[0007] To solve the above technical problems, this utility model adopts the following technical solution: a laser profiler support structure for road detection, including a base plate, a detachable support leg assembly on the lower surface of the base plate, an adjustment assembly on the outer surface of the base plate, and a mounting seat on the upper surface of the adjustment assembly. The adjustment assembly includes a DC motor, which is fixedly installed inside the base plate. A screw is fixedly connected to the output end of the DC motor. A protective shell is fixedly installed on the lower surface of the base plate. The bottom end of the screw is rotatably connected to the inner cavity of the protective shell. A slider is threaded onto the outer surface of the screw. Moving blocks are symmetrically fixedly connected to both sides of the slider. Guide grooves are symmetrically opened on both sides of the protective shell. A vertical rod is fixedly connected to the moving block through the guide groove, and a positioning seat is fixedly connected to the top end of the vertical rod. A servo motor is fixedly installed on the lower surface of the positioning seat. A first gear is fixedly connected to the output end of the servo motor through the lower surface of the positioning seat. A second gear is meshed with the outer surface of the first gear, and a circular plate is fixedly connected to the upper surface of the second gear. The mounting seat is fixedly installed on the upper surface of the circular plate.
[0008] Preferably, the detachable outrigger assembly includes mounting sleeves arranged in a ring array, the mounting sleeves being fixedly connected to the lower surface of the base plate in a ring array, the mounting sleeves having a threaded groove inside, and a threaded post being threadedly connected to the inner wall of the threaded groove, the bottom end of the threaded post being fixedly connected to the outrigger body.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] 1. This application uses an electric adjustment mechanism to replace traditional manual operation through an adjustment component, which can quickly and accurately adjust the support height and angle of the bracket automatically. Compared with manual adjustment, electric adjustment not only greatly improves the adjustment accuracy, but also significantly shortens the operation time, effectively solving the problem of tedious and time-consuming manual adjustment, and greatly improving the convenience of using the bracket.
[0011] 2. This application uses a detachable support leg assembly, which abandons the traditional support leg structure that can only be folded and retracted, and changes the support leg to a detachable design. Compared with the support leg structure that can only be retracted, removing the support leg can make the support structure occupy less space, effectively improving the portability of the support structure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example: Figure 1-4 As shown, this utility model provides a laser profiler support structure for road detection, including a base plate 1. The lower surface of the base plate 1 is provided with a detachable support leg assembly 3, which is easy to disassemble and reduces the space occupied during carrying. The outer surface of the base plate 1 is provided with an adjustment assembly 2, which enables the adjustment of the support. The upper surface of the adjustment assembly 2 is provided with a mounting base 4, which is used to install the laser profiler. This modular design makes the support structure more reasonable and facilitates installation, use and maintenance.
[0020] The adjustment assembly 2 includes a DC motor 204, which is fixedly installed inside the base plate 1. The output end of the DC motor 204 is fixedly connected to a screw 21. The DC motor 204 serves as a power source to drive the screw 21 to rotate. A protective shell 22 is fixedly installed on the lower surface of the base plate 1. The bottom end of the screw 21 is rotatably connected to the inner cavity of the protective shell 22 to ensure the smooth rotation of the screw 21. A slider 206 is threaded onto the outer surface of the screw 21. The rotation of the screw 21 drives the slider 206 to move.
[0021] The slider 206 has symmetrically fixedly connected movable blocks 207 on both sides. The movement of the slider 206 drives the movable blocks 207 to move. The protective shell 22 has symmetrically opened guide grooves 23 on both sides. The movable blocks 207 pass through the guide grooves 23 and are fixedly connected to the vertical rod 205, which facilitates the movement of the movable blocks 207 and drives the vertical rod 205 to move. The movable blocks 207 are slidably connected to the guide grooves 23 to ensure the accuracy of the movement direction of the movable blocks 207. The vertical rod 205 is slidably connected to the inside of the base plate 1, which plays a role in guiding the movement of the vertical rod 205. The top of the vertical rod 205 is fixedly connected to the positioning seat 27. The movement of the vertical rod 205 drives the positioning seat 27 to move, realizing the electric adjustment of the height of the positioning seat 27. Compared with manual adjustment, the electric adjustment method is faster and more accurate.
[0022] A servo motor 201 is fixedly mounted on the lower surface of the positioning seat 27. A support seat 25 for use with the servo motor 201 is also fixedly mounted on the lower surface of the positioning seat 27. The servo motor 201 is fixedly installed inside the support seat 25, which provides a stable mounting position for the servo motor 201. A through slot 24 for use with the support seat 25 is provided on the upper surface of the base plate 1. The through slot 24 avoids affecting the vertical movement of the support seat 25. The output end of the servo motor 201 passes through the lower surface of the positioning seat 27 and is fixedly connected to a first gear 202. A second gear 203 is meshed with the outer surface of the first gear 202. The servo motor 201 is driven by the meshing of the first gear 202 and the second gear 203. A circular plate 26 is fixedly connected to the upper surface of the second gear 203. The rotation of the second gear 203 drives the circular plate 26 to rotate. The mounting seat 4 is fixedly mounted on the upper surface of the circular plate 26. The rotation of the circular plate 26 drives the mounting seat 4 to rotate, thereby realizing the electric adjustment of the laser profiler angle.
[0023] The outer surface of the mounting base 4 is fixedly fitted with a positioning ring 29, and the outer surface of the positioning base 27 is provided with an annular groove 28. The positioning ring 29 and the annular groove 28 are connected in a damped rotational manner. The damped rotational connection between the positioning ring 29 and the annular groove 28 can maintain stability after being adjusted to a suitable angle and prevent shaking. This electric angle adjustment method has high precision, is easy to operate, and can quickly adjust the detection angle of the laser cross-section instrument.
[0024] The detachable support leg assembly 3 includes mounting sleeves 35 arranged in a ring array. The mounting sleeves 35 are fixedly connected to the lower surface of the base plate 1 in a ring array. The mounting sleeves 35 have a threaded groove 31 inside, and the inner wall of the threaded groove 31 is threaded with a threaded post 34. The bottom end of the threaded post 34 is fixedly connected to the support leg body 33. The support leg body 33 is connected to the threaded groove 31 of the mounting sleeve 35 through the threaded post 34 to form a detachable structure. When it is necessary to carry the support, the support leg body 33 can be detached. Compared with the support legs that can only be folded and retracted, this further reduces the space occupied by the support and makes it convenient to carry and transport. The bottom end of the support leg body 33 is fixedly connected to an anti-slip foot cover 32. The anti-slip foot cover 32 can increase the friction between the support leg and the ground, making the support more stable during use and improving the practicality and portability of the support structure.
[0025] Working principle: First, the laser profiler is securely installed on the mounting base 4 using bolts to seal the mounting components, ensuring the smooth progress of the testing work.
[0026] When the height of the bracket needs to be adjusted, the DC motor 204 is started by adjusting component 2. The DC motor 204 outputs power to drive the screw 21 to rotate. The bottom end of the screw 21 is rotatably connected to the inner cavity of the protective shell 22. The protective shell 22 is fixed to the lower surface of the base plate 1 to prevent external debris from entering and affecting the operation of the screw 21.
[0027] The slider 206, threadedly connected to the screw 21, converts rotational motion into linear motion as the screw 21 rotates, moving up and down along the screw 21. The movable blocks 207, symmetrically connected to both sides of the slider 206, pass through guide grooves 23 on both sides of the protective shell 22 and are connected to the vertical rod 205. The vertical rod 205 slides inside the base plate 1. The guide grooves 23 guide and limit the movable blocks 207, ensuring the vertical rod 205 rises and falls vertically, causing the top positioning seat 27 to rise or fall, thereby achieving precise adjustment of the height of the mounting seat 4.
[0028] When adjusting the angle of the laser profiler, the servo motor 201 is started. The output shaft of the servo motor 201 drives the first gear 202 to rotate. The first gear 202 meshes with the second gear 203, thereby driving the second gear 203 and the circular plate 26 fixedly connected to it to rotate.
[0029] Since the mounting base 4 is fixed on the upper surface of the circular plate 26, the mounting base 4 rotates accordingly to adjust the angle of the laser cross-section instrument. The positioning ring 29 on the outer surface of the mounting base 4 is embedded in the annular groove 28 on the outer surface of the positioning base 27 to form a damped rotation connection. After the angle is adjusted to the correct position, the mounting base 4 can be kept stable to avoid shaking that could affect the detection accuracy.
[0030] The through slot 24 on the upper surface of the base plate 1 provides space for the support base 25 to move, ensuring that the servo motor 201 is not obstructed by the base plate 1 when it is working, so that the angle adjustment can be carried out smoothly.
[0031] During the carrying and storage of the bracket, the detachable support leg assembly 3 plays an important role. When the bracket needs to be carried, the support leg body 33 can be rotated to unscrew the threaded post 34 from the threaded groove 31, thereby removing the support leg body 33, reducing the space occupied by the bracket, and making it easier to carry and transport.
[0032] When the bracket is in use, the support leg body 33 is screwed into the threaded groove 31 of the mounting sleeve 35 through the threaded post 34 for fixation. The anti-slip foot 32 at the bottom of the support leg body 33 contacts the ground to increase friction and prevent the bracket from sliding during the testing process, ensuring that the bracket provides stable support.
[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
