Description

A road and bridge slope detection device Technical Field

[0001] This invention relates to the field of road and bridge slope detection device technology, specifically to a road and bridge slope detection device. Background Technology

[0002] The slope of a road or bridge, which is divided into longitudinal slope and transverse slope, is a very important parameter in road and bridge design, directly affecting the safety, comfort, and service life of the road or bridge.

[0003] Traditional methods for measuring road and bridge slope involve marking and measuring at both ends, or using instruments such as total stations. However, these methods cannot measure the continuity of the slope or detect whether the longitudinal or transverse slope of the road or bridge is continuous, complete, or smooth, resulting in significant errors and safety hazards.

[0004] To address the aforementioned issues, this application proposes a road and bridge slope detection device. Summary of the Invention

The vehicle platform is located on the right side of the fixed base. The control box is mounted on the top of the vehicle platform, and the laser head is mounted on the top of the control box. An adjustment component for adjusting the position of the laser receiving plate is mounted on the fixed base. A cable take-up component is mounted inside the fixed base. A cable hole is located on the right side of the fixed base, and a detection component is mounted inside the cable hole. A vibration damping component is fixedly connected to the right side of the fixed base. A hook is connected to one side of the cable take-up component. The hook is located on the left side of the control box. A stabilizer for maintaining the laser head angle is mounted on the control box. Several wheels are located at the bottom of the vehicle platform, and a drive motor is located on the left or right side of each wheel for driving.

[0007] The controller is equipped with the wireless transceiver A, and the control box is equipped with the wireless transceiver B. The wireless transceiver A and the wireless transceiver B are used to control the start and stop of the drive motor.

[0008] The take-up assembly includes a roller, a take-up reel, a servo motor, a connecting rope, and a limiting wheel. The roller is fixedly connected to the inner side of the bottom of the mounting groove of the fixed base, and the take-up reel is rotatably connected to the top of the roller. The output shaft of the servo motor is located in the center hole of the take-up reel, and the servo motor is fixedly connected to the inner side wall of the mounting groove. The connecting rope is fixedly connected to the outer side of the take-up reel, and one end of the connecting rope is fixedly connected to the hook. The limiting wheel is located in the mounting groove and is used to clamp and limit the connecting rope.

[0009] The detection component includes a millimeter-wave locator and an infrared contact switch. The millimeter-wave locator is fixedly connected to the top of the inner wall of the wire hole of the fixing base. The infrared contact switch is fixedly connected to both the front and rear faces of the inner wall of the wire hole of the fixing base. The connecting rope is disposed between the two infrared contact switches.

[0010] The vibration damping assembly includes a bracket, a sliding sleeve, a fixed rod, and a sliding rod. The bracket is fixedly connected to the right end of the fixed base, and the sliding sleeve is fixedly connected to the other end of the bracket. An adaptation groove is provided on the inner side of the sliding sleeve, and the fixed rod is located in the adaptation groove. The sliding rod is slidably connected to the fixed rod, and the sliding rod is located above the connecting rope and in contact with the connecting rope.

[0011] The sliding rod is a lightweight foam rod, and a connecting groove is provided on the inner side of the sliding rod. The fixed rod and the sliding rod are slidably connected through the connecting groove.

[0012] The vehicle board is equipped with a steering assembly, which includes a transmission rod, a limit block, a driven wheel, a driving wheel, a motor, and a drive wheel motor. The bottom end of the transmission rod passes through the vehicle board and is connected to the wheel.

[0013] Two limiting blocks are fixedly connected to the outside of the transmission rod, and the two limiting blocks are respectively set at the top and bottom of the vehicle plate; the driven wheel is fixedly connected to the top of the transmission rod, the driving wheel is engaged with the outside of the driven wheel, the motor is rotatably connected to the bottom of the driving wheel through a rotating shaft, and the bottom of the motor is fixedly connected to the vehicle plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention utilizes a laser receiving plate, a vehicle platform, and a laser head. Based on the actual angle of the bridge, a stabilizer adjusts the laser head's angle to ensure it is parallel to the inclined surface of the road / bridge. The laser head then emits a laser signal, which is received by the laser receiving plate. Because the stabilizer maintains the laser head's parallelism to the inclined surface, it only experiences vertical displacement. The vehicle platform travels straight along the road / bridge surface until it reaches the highest point. If there are potholes or bumps in the road / bridge surface, the laser head will vibrate vertically, and the signal received by the laser receiving plate will also fluctuate vertically. When the millimeter-wave locator scans the connecting rope for positioning, the rope's inclination is transmitted to the controller after the millimeter-wave locator receives the reflected millimeter waves. This allows for synchronous measurement of the road surface inclination, performing a synchronized secondary detection for comparison. Through this detection, the overall continuity of the road / bridge slope can be assessed, improving detection accuracy and providing a basis for subsequent inspection and maintenance.

[0025] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0026] All standard parts used in this application can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art. The components used for circuit connection are all conventional models in the prior art.

[0027] Please refer to Figures 1-7. This invention provides a technical solution: a road and bridge slope detection device, including a slope measurement component 1. The slope measurement component 1 includes a fixed base 11, a controller 12, a laser receiving plate 13, a vehicle plate 14, a control box 15, and a laser head 16. The fixed base 11 has an inner mounting groove, on which the controller 12 is installed. The laser receiving plate 13 is installed on the fixed base 11. The vehicle plate 14 is located on the right side of the fixed base 11, and the control box 15 is installed at the top of the vehicle plate 14. A laser head 16 is mounted on the end of the device. An adjustment component 2 for adjusting the position of the laser receiving plate 13 is mounted on the mounting base 11. A wire take-up component 3 is mounted inside the mounting base 11. A wire hole is opened on the right side of the mounting base 11, and a detection component 4 is mounted inside the wire hole. A vibration damping component 5 is fixedly connected to the right side of the mounting base 11. A hook 6 is connected to one side of the wire take-up component 3. The hook 6 is located on the left side of the control box 15. A stabilizer 7 is mounted on the control box 15. The stabilizer 7 can be a commercially available product to keep the angle of the laser head 16 stable. In one embodiment of the present invention, three wheels 141 are provided at the bottom end of the vehicle plate 14. Two wheels 141 are located on the left side of the bottom end of the vehicle plate 14, and the other wheel 141 is located on the right side of the bottom end of the vehicle plate 14. The single wheel on the right side is a drive wheel, driven by a drive motor. The steering component 8 also adjusts the steering of the single wheel on the right side. The structure is reasonable and reduces the space occupied.

[0028] A wireless transceiver A121 is installed on the controller 12, and a wireless transceiver B151 is installed on the control box 15. The wireless transceiver A121 transmits the signal from the infrared contact switch 42 to the wireless transceiver B151, which then transmits the signal to the control box 15. The control box 15 controls the operation of the drive motor. As shown in Figure 7, the control box can also control the forward and reverse rotation and start / stop operation of the motor 85, ensuring that the drive wheel 84 of the motor 85 does not rotate arbitrarily.

[0029] Due to varying road and bridge slopes, the height of the laser receiver plate 13 needs to be adjusted in adjustment component 2 to facilitate signal reception from the laser head 16. Maintaining the forward and backward position of the laser receiver plate 13 is crucial, and during use, the signal transmitted by the laser head 16 should ideally be positioned roughly at the center of the laser receiver plate 13. This facilitates signal reception and allows for observation of laser head 16 fluctuations. Existing telescopic or rotating rod mechanisms can be used to adjust the position of the laser receiver plate 13.

[0030] The take-up assembly 3 includes a roller 31, a take-up reel 32, a servo motor 33, a connecting rope 34, and a limiting wheel 35. The roller 31 is fixedly connected to the inner side of the bottom of the mounting groove of the fixed base 11. The top of the roller 31 is rotatably connected to the take-up reel 32 via a rotating shaft. The output end of the servo motor 33 is fixedly connected to the take-up reel 32. The servo motor 33 is fixedly connected to the inner side wall of the mounting groove. The connecting rope 34 is fixedly connected to the outer side of the take-up reel 32. The right end of the connecting rope 34 is fixedly connected to the hook 6. Two limiting wheels 35 are provided on the right side of the take-up reel 32, which are arranged vertically. The connecting rope 34 follows the hook 6. As shown in Figure 3, the connecting rope 34 on the right side of the limiting wheel 35 is parallel to the road and bridge ground due to the limiting of the two limiting wheels 35. The hook 6 pulls the connecting rope 34, and the servo motor 33 rotates, causing the take-up reel 32 to rotate and drive the connecting rope 34 out. The servo motor 33 controls the speed to keep the take-up reel 32 pulling the connecting rope 34 and keeping the connecting rope 34 taut. The millimeter-wave positioner 41 operates to emit millimeter waves to detect the position and angle of the connecting rope 34 in the wire control. If the vehicle platform 14 tilts during travel, it will cause the connecting rope 34 to tilt. If the connecting rope 34 contacts the infrared contact switch 42, it indicates that the vehicle platform 14 is tilted too much.

[0031] The detection component 4 includes a millimeter-wave locator 41 and an infrared contact switch 42. The millimeter-wave locator 41 is fixedly connected to the top of the inner wall of the wire hole of the fixing base 11. The front and rear faces of the inner wall of the wire hole of the fixing base 11 are fixedly connected to the infrared contact switch 42. The connecting rope 34 is set between the two infrared contact switches 42. When the millimeter-wave locator 41 scans the connecting rope 34 for positioning, the connecting rope 34 tilts left and right. The tilt of the connecting rope 34 is transmitted to the controller 12 after the millimeter-wave locator 41 receives the reflected millimeter wave. It can be used to synchronously measure the continuous tilt of the road surface with the laser receiving plate 13. If the vehicle plate 14 tilts during driving, it will cause the connecting rope 34 to tilt. This tilt is a forward and backward tilt. If the connecting rope 34 contacts the infrared contact switch 42, it indicates that the vehicle plate 14 tilts excessively forward and backward.

[0032] It should be noted that the connecting rope 34 has its own weight. Because the connecting rope 34 is relatively long after it is extended, the tilt of the connecting rope 34 changes uniformly and linearly according to the change in the extended length of the connecting rope 34. The center of gravity of the connecting rope 34 is at the lowest position. However, due to potholes and bumps causing discontinuities in the road surface tilt, the tilt of the connecting rope 34 changes randomly and suddenly. By comparing the tilt changes of the connecting rope 34 scanned by the millimeter-wave locator 41 with the signal fluctuations received by the laser head 16 by the laser receiving board 13, a secondary confirmation is performed, which improves the accuracy of detecting the continuity of road and bridge ground tilt.

[0033] The vibration damping assembly 5 includes a bracket 51, a sliding sleeve 52, a fixed rod 53, and a sliding rod 54. The bracket 51 is fixedly connected to the right end of the fixed base 11, and the sliding sleeve 52 is fixedly connected to the other end of the bracket 51. An adaptation groove is provided on the inner side of the sliding sleeve 52. A fixed rod 53 is fixedly connected between the top and bottom ends of the inner sidewall of the adaptation groove. The sliding rod 54 is slidably connected to the inner side of the fixed rod 53. The sliding rod 54 is slidably connected to the connecting rope 34. The sliding rod 54 can be a cylindrical structure made of foam material. A connecting groove is provided on the inner side of the sliding rod 54. The outer side of the fixed rod 53 is slidably connected to the connecting groove. When the vehicle platform 14 moves and pulls the connecting rope 34 through the hook 6, the connecting rope 34 slides under the sliding rod 54. The connecting rope 34 and the sliding rod 54 are in contact, so that the sliding rod 54 connects the rope 34 to the connecting rope 34. The vibration of the connecting rope 34 caused by external factors such as wind disturbance is eliminated. The section of the connecting rope 34 between the limit wheel 35 and the sliding rod 54 is scanned by the millimeter-wave locator 41 and found to be flat and without vibration. The bracket 51 supports the sliding sleeve 52, and the sliding sleeve 52 supports the fixed rod 53. The sliding rod 54 slides on the fixed rod 53 through the connecting groove, making the connecting rope 34 more stable. The sliding rod 54 is relatively light, and the tension of the connecting rope 34 makes the change of the sliding rod 54 pressing the connecting rope 34 small and negligible. When the millimeter-wave locator 41 scans the connecting rope 34 for positioning, the tilt of the connecting rope 34 is transmitted to the controller 12 after the millimeter-wave locator 41 receives the reflected millimeter waves. It can be used to synchronously measure the continuous tilt of the road surface together with the laser receiving plate 13.

[0034] The steering assembly 8 includes a transmission rod 81, a limiting block 82, a driven wheel 83, a driving wheel 84, a motor 85, and a drive wheel motor. The transmission rod 81 is fixedly connected to the top of the wheel 141 at the right end. The limiting block 82 is fixedly connected to the outside of the transmission rod 81. The two limiting blocks 82 are respectively set at the top and bottom of the vehicle plate 14 to limit the transmission rod and keep it rotating smoothly. The driven wheel 83 is fixedly connected to the top of the transmission rod 81. The driving wheel 84 is engaged with the outside of the driven wheel 83. The bottom of the driving wheel 84 is rotatably connected to the motor 85 through a rotating shaft. The bottom of the motor 85 is fixedly connected to the vehicle plate 14. The drive wheel motor is installed on the wheel 141 at the right end. The output end of the drive wheel motor is fixedly connected to the roller of the wheel 141 at the right end. As described above, if the vehicle platform 14 tilts during travel, it will cause the connecting rope 34 to tilt back and forth. When the connecting rope 34 contacts the infrared contact switch 42, it indicates that the vehicle platform 14 has tilted excessively. When the connecting rope 34 contacts the rear infrared contact switch 42, the motor 85 reverses its rotation, causing the drive wheel 84 to rotate counterclockwise. The drive wheel 84 meshes with the driven wheel 83, causing the drive wheel 84 to rotate clockwise. The limit block 82 limits the transmission rod 81. The rotation of the driven wheel 83, through the transmission rod 81, drives the wheel 141 to rotate forward. The wheel 141 guides the movement of the motor 85 in reverse, causing the vehicle platform 14 to move forward, thus separating the connecting rope 34 from the infrared contact switch 42 at the rear. The drive wheel 84 then rotates forward again, causing the wheel 141 to reset. If the connecting rope 34 contacts the infrared contact switch 42 at the front, the motor 85 rotates forward, causing the wheel 141 to rotate backward, and the vehicle platform 14 to move backward, thus separating the connecting rope 34 from the infrared contact switch 42 at the front. The drive wheel 84 then rotates in reverse again, causing the wheel 141 to reset, maintaining the linear movement of the vehicle platform 14.

[0035] Working Principle: This device is powered by a built-in battery. Both the controller 12 and control box 15 are equipped with batteries. The mounting base 11 is placed near the edge of the bridge abutment, and the vehicle platform 14 is placed to the right of the mounting base 11. The connecting rope 34 is pulled out and secured to the hook 6. The drive wheel motor on the wheel 141 then drives the right wheel 141, which in turn moves the vehicle platform 14 to the right. The two left wheels 141 follow the movement of the vehicle platform 14. The angle of the laser head 16 is adjusted according to the actual angle of the bridge using the stabilizer 7, ensuring that the laser head 16 is aligned with the bridge surface. The inclined surface of the road is parallel, and then the laser head 16 emits a laser signal, which is received by the laser receiving plate 13. Because the stabilizer 7 is running, the laser head 16 can remain parallel to the inclined surface of the road and bridge. The laser head 16 will only move up and down. Then the vehicle plate 14 moves straight along the road and bridge surface until it reaches the highest point of the road and bridge surface. If there are potholes or bumps on the road and bridge surface, the laser head 16 will shake up and down. The signal emitted by the laser head 16 is also received by the laser receiving plate 13 as fluctuating up and down. This can detect the overall continuity of the road and bridge surface slope and complete the slope detection of the road and bridge surface.

[0036] The laser receiving board 13 sends the fluctuation status to the mobile terminal via the controller 12, or a display screen is installed on the mounting base 11. The controller 12 displays the status of the laser head 16 signal received by the laser receiving board 13 on the display screen. Similarly, the laser receiving board 13 is placed on one side of the road bridge in the lateral direction, and the laser head 16 is moved or placed on the other side of the road bridge in the lateral direction to measure the road bridge slope and the continuity of the road bridge slope.

[0037] When the vehicle platform 14 moves and the hook 6 pulls the connecting rope 34, the connecting rope 34 slides under the sliding rod 54. The contact between the connecting rope 34 and the sliding rod 54 eliminates the shaking of the connecting rope 34 caused by external factors such as wind disturbance. The sliding rod 54 is relatively light, and the tension of the connecting rope 34 makes the change in the pressure of the sliding rod 54 on the connecting rope 34 small and negligible. When the millimeter-wave locator 41 scans the connecting rope 34 for positioning, the tilt of the connecting rope 34 is transmitted to the controller 12 after the millimeter-wave locator 41 receives the reflected millimeter waves. It can be used to synchronously measure the continuous tilt of the road surface with the laser receiving plate 13 and perform synchronous secondary detection for comparison.
