[0002] A laser road roughness tester is a physical property testing instrument used in the field of transportation engineering.

[0003] The laser road roughness tester consists of a distance sensor. When installing it, bolts are generally used for fixation. According to actual usage requirements, its angle needs to be adjusted. However, during general use, multiple components are required to separately fix and limit its angle and position. Multiple components need to be adjusted at one time, so it is not convenient to use, and it is difficult to simplify the fixing structure to facilitate the adjustment of its angle and position.

[0004] Therefore, a distance sensor fixing disk of a laser road detector is proposed. Content of the Utility Model

[0025] Such as Figures 1-4As shown in the figure, a distance sensor fixing disk of a laser road detector includes a laser road detector mounting bracket 10. A rotating rod 1 is rotatably arranged on the laser road detector mounting bracket 10. A connecting disk 3 is arranged at the top end of the rotating rod 1. A plurality of limit jacks 301 are opened at the top end of the connecting disk 3. A fixing disk 5 is movably arranged above the connecting disk 3. A plurality of limit inserting rods 501 adapted to the limit jacks 301 are arranged at the bottom end of the fixing disk 5. A protective frame 7 is arranged at the top end of the mounting rod 4. A distance sensor 8 is arranged inside the protective frame 7. A limiting member 6 for limiting the angle and position of the fixing disk 5 is arranged on the laser road detector mounting bracket 10. The limiting member 6 includes a first slide rail 601 and a second slide rail 602 arranged at the top end of the laser road detector mounting bracket 10, and two first limiting blocks 606 and second limiting blocks 607 slidably arranged on the first slide rail 601 and the second slide rail 602. Specifically, when the limit inserting rods 501 on the fixing disk 5 are inserted into the limit jacks 301 on the connecting disk 3, the distance sensor 8 and the rotating rod 1 can rotate synchronously. The first limiting block 606 in the arranged limiting member 6 can clamp the connecting disk 3, so the angle of the distance sensor 8 can be limited. At the same time, the arranged second limiting block 607 can clamp the fixing disk 5 to fix the position of the distance sensor 8 and prevent it from separating from the connecting disk 3. When the distance sensor 8 needs to be disassembled for repair or replacement, the limit on it can be cancelled by using the limiting member 6, and then the distance sensor 8 can be taken down. It is also more convenient to adjust its angle. There is no need to use bolts to fix and limit it. Using a limiting member 6 can realize the functions of fixing its angle and position, so it is more convenient to use.

[0026] As Figure 2 shown, an indicating needle 101 is arranged on the rotating rod 1. An installation sleeve 2 is arranged at the bottom end of the laser road detector mounting bracket 10. A scale groove is opened on the outer side of the installation sleeve 2. Specifically, when the rotating rod 1 is rotated, the indicating needle 101 can rotate on the outer surface of the installation sleeve 2. The angle of the rotating rod 1 can be accurately adjusted through the scale groove, so the angle of the distance sensor 8 can also be accurately adjusted.

[0027] As Figure 3 and 4 shown, a uniformly arranged first limiting tooth is arranged on the outer side of the connecting disk 3. A second limiting tooth meshing with the first limiting tooth is arranged on the inner side of the first limiting block 606. The second limiting block 607 is arranged at the top end of the first limiting block 606. Specifically, when the two first limiting blocks 606 approach each other, they can play a role in clamping the connecting disk 3, so they can play a role in limiting the angle of the connecting disk 3.

[0028] As Figure 1 and2 As shown, two sliders 605 are slidingly arranged inside the first slide rail 601 and the second slide rail 602, a motor 603 is arranged on one side of the interior of the second slide rail 602, a bidirectional screw rod 604 is connected to the main shaft end of the motor 603, the slider 605 inside the second slide rail 602 is threadedly sleeved on the bidirectional screw rod 604, and a first limit block 606 is arranged on the top of the slider 605; specifically, the motor 603 can drive the bidirectional screw rod 604 to rotate when it is working, and the rotation of the bidirectional screw rod 604 can drive the two first limit blocks 606 and the second limit blocks 607 to approach or move away from each other, thereby realizing the fixed limit of the angle and position of the distance sensor 8.

[0029] like Figure 2 As shown, a shock absorbing component 9 is arranged inside the protection frame 7 to play a shock absorbing and limiting role for the distance sensor 8.

[0030] like Figure 2 As shown, the shock-absorbing component 9 includes a shock-absorbing pad 901 arranged at the top end of the protection frame 7 and a damping telescopic rod 902 arranged on the side of the top end of the protection frame 7, a spring 903 is sleeved on the damping telescopic rod 902, and the telescopic end of the damping telescopic rod 902 is connected to a limiting plate 904; specifically, the shock-absorbing pad 901, the damping telescopic rod 902 and the spring 903 can play a shock-absorbing role for the distance sensor 8 to avoid it from being damaged due to large shaking during road surface detection.

[0031] In summary: the limiting rod 501 on the fixed disk 5 is inserted into the limiting hole 301 on the connecting disk 3, so that the distance sensor 8 and the rotating rod 1 can rotate synchronously. The first limiting block 606 in the limiting member 6 can clamp the connecting disk 3, thereby limiting the angle of the distance sensor 8. At the same time, the second limiting block 607 can clamp the fixed disk 5, so that the position of the distance sensor 8 is fixed to avoid separation from the connecting disk 3. When the distance sensor 8 needs to be disassembled for maintenance or replacement, the distance sensor 8 can be removed by using the limiting member 6 to cancel the limit on it, and its angle adjustment is also more convenient. There is no need to use bolts to fix and limit it. Using one limiting member 6 can achieve the function of fixing its angle and position, so it is more convenient to use.

[0032] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
