[0031] Embodiment 1:

[0032] Please refer to Figure 1-Figure 4 The present embodiment provides a tunnel pavement monitoring and early warning device, comprising: a supporting mechanism, the supporting mechanism comprising a column 1 and a beam 2, the number of the columns 1 being two, the two columns 1 being symmetrically arranged at the two ends of the beam 2, and the ends of the beam 2 being slidably connected to the columns 1; a detecting mechanism, the detecting mechanism comprising a fixed seat 3, a sliding seat 4, a first ranging head 5, a second ranging head 6 and a third ranging head 7, the fixed seat 3 being arranged at the end of the beam 2, the first ranging head 5 and the second ranging head 6 being both arranged on the fixed seat 3, the sliding seat 4 being slidably arranged on the beam 2, the third ranging head 7 being arranged on the sliding seat 4, the first ranging head 5 being used to detect the distance between the fixed seat 3 and the sliding seat 4, the second ranging head 6 and the third ranging head 7 being aligned with the road surface; a leveling mechanism for leveling the beam 2 is arranged on the beam 2.

[0033] In this embodiment, the support mechanism is used to support and lift the detection mechanism for obtaining road surface data, so as to form a drop, thereby obtaining the accuracy data of the road surface. The column 1 is used to lift and support the beam 2. The beam 2 is used to install the detection mechanism.

[0034] In this embodiment, the detection mechanism is used to obtain the drop data 18 and width data 17 of the transverse slope of the road surface, and the transverse slope angle data is calculated by the drop data 18 and the width data 17. Specifically, the fixed seat 3 is used to install the first distance measuring head 5 and the second distance measuring head 6. The first distance measuring head 5 is used to obtain the distance data between the fixed seat 3 and the ground. The second distance measuring head 6 is aligned with the third distance measuring head 7, so as to obtain the distance data between the fixed seat 3 and the sliding seat 4. The third distance measuring head 7 is used to obtain the distance data between the sliding seat 4 and the ground. The difference between the distance data obtained by the first distance measuring head 5 and the distance data obtained by the third distance measuring head 7 is the drop data 18 of the transverse slope, and the distance data obtained by the second distance measuring head 6 is the width data 17 of the road surface. The transverse slope, the drop data 18 and the width data 17 form a right triangle. The data of the two right angle sides are known, so the inclination angle of the transverse slope surface can be obtained.

[0035] In this embodiment, the leveling mechanism is used to find the horizontal position of the beam 2, so as to accurately obtain the transverse slope angle of the detection point.

[0036] Preferably, the leveling mechanism is a spirit level 8 .

[0037] Please refer to Figure 1-Figure 3 In some implementations of the present embodiment, a slide groove 9 is provided on the cross beam 2, and the sliding seat 4 is slidably arranged in the slide groove 9. A screw rod 10 is arranged in the slide groove 9, and the screw rod 10 is passed through the sliding seat 4, and the screw rod 10 is threadedly connected to the sliding seat 4.

[0038] In this embodiment, the slide groove 9 is used to carry the reciprocating motion of the sliding seat 4, so as to continuously obtain the cross slope data and improve the accuracy of data acquisition. The screw 10 is used to drive the sliding seat 4 to move in the slide groove 9. When the screw rotates, due to the guiding effect of the spiral groove, the sliding seat 4 will move along the axial direction of the screw, thereby driving the sliding seat 4 to move along the length direction of the beam 2.

[0039] Please refer to Figure 1-Figure 3 In some implementations of this embodiment, a driving motor 11 for driving the screw rod 10 to rotate is provided on the above-mentioned beam 2.

[0040] In this embodiment, the driving motor 11 is used to drive the screw rod 10 to rotate at a constant speed, so as to obtain the continuously changing value of the cross slope angle at a constant speed.

[0041] Preferably, the drive motor 11 is a servo motor, which is an engine that controls the operation of mechanical components in a servo system and is an auxiliary motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object. The excellent control accuracy of the servo motor is an ideal material for the drive motor 11, but it is not limited to the above-mentioned servo motor material, and can also be other materials with similar performance.

[0042] Please refer to Figure 1-Figure 3 In some implementations of the present embodiment, a sliding sleeve 12 is provided between the crossbeam 2 and the column 1. The sliding sleeve 12 is sleeved on the column 1. A locking knob 13 is passed through the sliding sleeve 12. One end of the locking knob 13 extends into the sliding sleeve 12 and abuts against the outer wall of the column 1. The locking knob 13 is threadedly connected to the sliding sleeve 12.

[0043] In this embodiment, the above-mentioned sliding sleeve 12 is used for sliding guidance of the beam 2 on the column 1. The beam 2 can be locked and fixed on the column 1 as a whole through the locking knob 13 on the sliding sleeve 12, which is convenient for stably obtaining the accurate slope value of the cross slope section to be detected.

[0044] Please refer to Figure 1-Figure 3 In some implementations of this embodiment, a driving wheel is provided on the column 1, and the driving wheel is a universal wheel 14.

[0045] In this embodiment, the driving wheels are used by the inspector to move the entire device on the road surface, thereby reducing the difficulty of the operator's carrying and saving time and effort.

[0046] Preferably, the driving wheel is a universal wheel 14 .

[0047] Please refer to Figure 1-Figure 3 In some implementations of this embodiment, a power supply 15 is provided on the above-mentioned beam 2.

[0048] In this embodiment, the power supply 15 is used to provide sufficient electrical energy to various electrical appliances, so as to facilitate the acquisition of cross slope data for long-distance tunnels.

[0049] Please refer to Figure 1-Figure 3 In some implementations of the present embodiment, a control panel 16 is provided on the crossbeam 2 , and the control panel 16 is electrically connected to the power supply 15 , the first ranging head 5 , the second ranging head 6 and the third ranging head 7 , respectively.

[0050] In this embodiment, the control panel 16 is used to calculate and integrate the data obtained by the first ranging head 5, the second ranging head 6 and the third ranging head 7 and to display the cross slope data value finally obtained, which greatly improves the convenience of data processing and reduces human calculation errors.

[0051] Please refer to Figure 1-Figure 3 In some implementations of this embodiment, the first ranging head 5, the second ranging head 6 and the third ranging head 7 are all infrared ranging heads.

[0052] In this embodiment, the infrared rangefinder includes an infrared transmitter and an infrared receiver. The infrared transmitter generates an infrared signal of a certain frequency and irradiates it onto the road surface to be detected. Part of the infrared light is reflected back by the road surface and received by the infrared receiver. By measuring the intensity or time difference of the reflected infrared light, the distance between the target object and the sensor can be determined. The infrared rangefinder has good adaptability to the reflection and scattering characteristics of different objects, and can perform stable measurements under various materials and surface conditions, with high data acquisition accuracy. It can also reduce the cost and error rate of manual measurement.

[0053] During use, when it is necessary to accurately obtain the cross slope angle, the entire device is transported to the detection point, the cross beam 2 is placed vertically with the road traffic marking, and then the leveling mechanism is observed. By adjusting the position of the sliding sleeve 12 on the column 1, the cross beam 2 is in a horizontal state, the control panel 16 is opened, and the screw rod 10 is controlled to rotate. The first distance measuring head 5, the second distance measuring head 6 and the third distance measuring head 7 continuously obtain the distance data of each position when the sliding seat 4 moves, and the cross slope angle of the road surface to be measured can be output through the control panel 16.

[0054] When it is necessary to quickly obtain whether the cross slope angle exceeds the standard, adjust the distance between the sliding sleeves 12 at both ends of the beam 2 and the ground so that the columns 1 at both ends of the beam 2 are located on the markings on both sides of the road surface, and keep the road surface markings perpendicular to the beam 2. Observe the inclination angle of the leveling mechanism and keep moving along the markings to obtain whether the cross slope angle value in the tunnel to be tested exceeds the standard.

[0055] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
