Technical Field

[0001] This utility model relates to the field of road inspection equipment technology, specifically to a laser profiler mounting device for a road inspection vehicle. Background Technology

[0002] In the field of road inspection, laser profilers, as high-precision testing equipment, are widely used to measure parameters such as road surface smoothness and rut depth. The stability of their installation and the ease of adjustment directly affect the accuracy of the test data and the efficiency of the inspection.

[0003] However, existing technologies still have the following problems:

[0004] In existing technologies, most laser profiler installation devices adopt fixed installation or simple manual adjustment structures. Fixed installation makes it difficult to flexibly adjust the device position according to different road inspection needs, resulting in a limited inspection range. Manual adjustment structures are not only cumbersome and inefficient, but also prone to shaking during adjustment, affecting the accuracy of inspection data. In addition, existing devices have low modularity and complex connection methods between components, which is not conducive to the rapid disassembly and maintenance of the equipment. The lack of an effective management structure for cables makes them prone to tangling and pulling during inspection, reducing the reliability of equipment operation.

[0005] To address the aforementioned problems, the inventors have proposed a laser profiler mounting device for road inspection vehicles. Utility Model Content

[0017] 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.

[0018] Example: Figure 1-3 As shown, this utility model provides a laser profiler installation device for a road inspection vehicle, including a bracket 1. A carrier plate 2 is slidably provided on the lower surface of the bracket 1, and an installation plate 3 is detachably provided on the lower surface of the carrier plate 2. A lead screw 11 is rotatably provided inside the bracket 1. A motor 12 is fixedly provided on one side of the bracket 1, and a protective sleeve 17 is fixedly provided on one side of the bracket 1. The motor 12 is fixedly installed inside the protective sleeve 17. The output end of the motor 12 passes through the bracket 1 and is fixedly connected to the lead screw 11. A triangular plate 13 is threadedly sleeved on the outer surface of the lead screw 11. After the motor 12 is started, its output shaft drives the lead screw 11 to rotate inside the bracket 1. Due to the threaded engagement between the lead screw 11 and the triangular plate 13, the triangular plate 13 will move horizontally along the axial direction of the lead screw 11.

[0019] A limiting post 16 is symmetrically fixed inside the bracket 1, and the limiting post 16 passes through the triangular plate 13. A connecting plate 14 is fixed on the lower surface of the triangular plate 13, and a slider 15 is symmetrically fixed on the upper surface of the connecting plate 14. The slider 15 is locked on the bracket 1. The limiting post 16 passes through the triangular plate 13 and is fixed on both sides of the bracket 1, restricting the rotational freedom of the triangular plate 13 and allowing it to move linearly along the lead screw 11. At the same time, the slider 15 on the connecting plate 14 is engaged in the slide groove of the bracket 1, further ensuring that the triangular plate 13 and the connecting plate 14 move stably in the horizontal direction and avoid deviation or shaking.

[0020] The lower surface of the connecting plate 14 is detachably connected to the carrier plate 2. The lower side of the connecting plate 14 is clipped onto the carrier plate 2, and the carrier plate 2 and the connecting plate 14 are connected by bolts. The connecting plate 14 is connected to the carrier plate 2 by bolts, and the carrier plate 2 is fixed to the mounting plate 3 by the mounting block 21. Therefore, the horizontal displacement of the triangular plate 13 will be transmitted to the connecting plate 14, the carrier plate 2 and the mounting plate 3 in sequence, driving the laser cross-section instrument to adjust its position in the horizontal direction to meet the needs of different detection scenarios.

[0021] The bracket 1 is symmetrically fixed with bolt mating plates 18 on the upper inner side, and the upper surface of the bolt mating plates 18 is provided with through bolt grooves. The bracket 1 can be firmly installed on the chassis of a road inspection vehicle or other carrier through the bolt grooves on the bolt mating plates 18. Its stable base design provides reliable support for the horizontal adjustment function.

[0022] The lower surface of the carrier plate 2 is fixedly provided with an installation block 21, and the upper surface of the mounting plate 3 is symmetrically provided with a clamping plate 22. The installation block 21 is clamped between the two clamping plates 22, and the clamping plates 22 and the installation block 21 are connected by bolts. The two sides of the mounting plate 3 are symmetrically provided with mounting bolt holes 31. The carrier plate 2 and the connecting plate 14, and the mounting plate 3 and the carrier plate 2 are all fastened with bolts, which facilitates quick disassembly and maintenance. During the inspection, the position of the mounting plate 3 can be flexibly adjusted or different specifications of the mounting plate can be replaced according to the requirements of road width, inspection range, etc.

[0023] One side of the mounting plate 3 is connected to a side plate 32 by bolts, and three cable management posts 33 are fixed on the outer side of the side plate 32. Cable management grooves 34 are symmetrically opened on both sides of the cable management posts 33. The cable management posts 33 and cable management grooves 34 on the side plate 32 of the mounting plate 3 can orderly store the data cable of the laser profiler, prevent tangling and pulling during horizontal movement, and ensure the stability of equipment operation.

[0024] The motor 12 is existing technology and will not be described in detail here. In addition, this utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail here.

[0025] Working principle: After the motor 12 is started, its output shaft drives the lead screw 11 to rotate in the bracket 1. Since the lead screw 11 is threadedly engaged with the triangle plate 13, the triangle plate 13 will move horizontally along the axis of the lead screw 11.

[0026] The limiting post 16 passes through the triangular plate 13 and is fixed to both sides of the bracket 1, restricting the rotational freedom of the triangular plate 13 and allowing it to move linearly along the lead screw 11. At the same time, the slider 15 on the connecting plate 14 is engaged in the groove of the bracket 1, further ensuring that the triangular plate 13 and the connecting plate 14 move stably in the horizontal direction and avoids deviation or shaking.

[0027] The connecting plate 14 is connected to the carrier plate 2 by bolts, and the carrier plate 2 is fixed to the mounting plate 3 by the mounting block 21. Therefore, the horizontal displacement of the triangular plate 13 will be transmitted to the connecting plate 14, the carrier plate 2 and the mounting plate 3 in sequence, driving the laser cross-section instrument to adjust its position in the horizontal direction to meet the needs of different detection scenarios.

[0028] The carrier plate 2 and the connecting plate 14, and the mounting plate 3 and the carrier plate 2 are all fastened with bolts, which facilitates quick disassembly and maintenance. During the inspection, the position of the mounting plate 3 can be flexibly adjusted or different specifications of mounting plates can be replaced according to the requirements of road width, inspection range, etc.

[0029] The cable management posts 33 and cable management channels 34 on the side plate 32 of the mounting plate 3 can orderly store the data cables of the laser profiler, prevent tangling and pulling during horizontal movement, and ensure the stability of equipment operation.

[0030] The bracket 1 can be firmly installed on the chassis of a road inspection vehicle or other carrier through the bolt groove on the bolt mating plate 18. Its stable base design provides reliable support for the horizontal adjustment function.

[0031] 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.
