Description

Technical Field

[0001] This invention relates to the field of road engineering surveying technology, and specifically to a high-precision road slope laser calibration construction device and its control method. Background Technology

[0002] In road construction, accurate measurement and calibration of slope are crucial for ensuring road surface drainage, driving safety, and compliance with design requirements. Currently, road slope measurement relies heavily on traditional instruments such as levels and total stations, which suffer from problems such as complex operation, poor real-time performance, and low automation. Existing technologies have significant shortcomings for dynamic slope calibration during construction: on the one hand, the measuring devices have poor terrain adaptability and struggle to maintain a stable measurement benchmark on complex and undulating construction surfaces; on the other hand, the angles of the measuring sensors cannot be synchronized with the slope in real time, automatically, and with high precision, resulting in delayed or inaccurate measurement data.

[0003] Furthermore, the bumps and vibrations generated by the drive unit in the construction environment can easily be transmitted to the core detection unit, seriously affecting the measurement stability and reliability of precision sensors such as lasers.

[0004] Therefore, how to achieve adaptive adjustment of the measuring device to the terrain, isolate external vibration interference, and ensure real-time high-precision synchronization of the detection angle with the slope has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-precision road slope laser calibration construction device and its control method to achieve automated, high-precision, and interference-resistant real-time slope measurement and calibration.

[0006] To achieve the above objectives, the present invention provides a high-precision road slope laser calibration construction device and its control method, comprising a base, a drive wheel installed at the bottom of the base, and a control device for controlling the drive wheel, characterized in that it further comprises: An adjustment mechanism is mounted on the base; A calibration mechanism is connected to the top of the adjustment mechanism; The adjustment mechanism is used to support the calibration mechanism and can adaptively adjust the height and angle of the calibration mechanism according to changes in terrain, while buffering the vibration transmitted by the base. The calibration mechanism includes a contact sensing element for rolling contact with the slope to sense the slope, a laser detector for synchronously adjusting the angle based on the movement of the contact sensing element, and a transmission element connecting the contact sensing element and the laser detector.

[0007] By adopting this technical solution, an independent adjustment mechanism is set up to be responsible for the stability of the physical posture, and an independent calibration mechanism is set up to be responsible for the precise synchronization of the measurement reference. This allows the entire device to structurally decouple the complex construction environment from the precise measurement process, thereby achieving high-stability and high-precision dynamic measurement as a whole.

[0008] Furthermore, the adjustment mechanism includes: A fixed frame is fixedly connected to the base; A movable support assembly is slidably connected to the fixed frame and can move up and down along it; the calibration mechanism is installed on the top of the movable support assembly. A buffer, connected between the movable support assembly and the mounting base of the calibration mechanism, is used to attenuate the transmission of vibrations from the movable support assembly to the calibration mechanism.

[0009] By adopting this technical solution, the fixed frame provides a stable reference for adjustment; the sliding connection between the movable support assembly and the fixed frame is the most direct and reliable mechanical way to achieve height adaptive adjustment; and placing the buffer between the movable support assembly and the calibration mechanism can specifically attenuate the vibration from the movable support assembly, preventing it from directly affecting the measurement accuracy of the calibration mechanism installed on top.

[0010] Furthermore, the fixed frame includes a chassis and a guide rod vertically fixed to the chassis; The movable support assembly includes: The first sliding seat is sleeved on the guide rod; At least one retractable support rod, one end of which is hinged to the first sliding seat; The second connecting seat is hinged to the other end of the support rod and serves as the mounting base for the calibration mechanism.

[0011] By adopting this technical solution, the sleeve relationship between the guide rod and the first sliding seat forms a high-precision linear motion pair, ensuring accurate guidance and no shaking during the adjustment process; the first sliding seat, support rod, and second connecting seat form a linkage mechanism through hinges, which smoothly converts the vertical linear motion of the first sliding seat into the composite motion of the second connecting seat in space through the extension, contraction, and rotation of the support rod, thereby not only adjusting the height but also adaptively fine-tuning the angle, and the linkage structure itself has good stress stability and load-bearing capacity.

[0012] Furthermore, the buffer includes: Elastic components; The mounting base is rotatably connected to the second connecting base; A linkage buffer assembly elastically connects the first sliding seat to the mounting seat. The elastic element, as part of the linkage buffer assembly, is used to absorb the vibration energy of the first sliding seat.

[0013] By adopting this technical solution, when the first sliding seat vibrates, the vibration energy forces the elastic element to deform through the connecting rod buffer assembly, thereby converting the kinetic energy into elastic potential energy and dissipating it partially. The design of the mounting seat and the second connecting seat being rotatably connected allows for a small relative rotation between the mounting seat and the second connecting seat when the buffer is in operation. This avoids the additional stress caused by the rigid constraints on the vibration transmission path and improves the smoothness and lifespan of the buffer.

[0014] Furthermore, the link buffer assembly includes: Guide rod fixed to the mounting base; A sliding sleeve that is slidably fitted onto the guide rod; A connecting rod whose two ends are respectively hinged to the sliding sleeve and the first sliding seat; The elastic element is a spring sleeved on the guide rod. One end of the spring is limited by a first stop fixed on the guide rod, and the other end is limited by a second stop fixed on the sliding sleeve.

[0015] By adopting this technical solution, the cooperation between the guide rod and the sliding sleeve forms a low-friction, high-precision linear guide pair, ensuring that the buffering action is strictly performed along the axial direction of the guide rod; the hinge of the connecting rod transforms the vibration components of the first sliding seat that may come from different directions into a precise linear reciprocating motion of the driving sliding sleeve along the guide rod; the spring is restricted between two stops on the guide rod, so that the compression and extension stroke of the spring is precisely controlled and the preload is adjustable, providing linear, controllable and reliable damping characteristics, which can optimize the buffering for vibrations in a specific frequency range.

[0016] Furthermore, the contact sensing component includes a calibration plate and at least one roller rotatably mounted on the calibration plate; The transmission component includes a first rotating shaft and a second rotating shaft rotatably mounted on the mounting bracket of the calibration mechanism. The first rotating shaft is fixedly connected to the calibration plate, and the second rotating shaft is fixedly connected to the laser detector. The first rotating shaft and the second rotating shaft are connected by a synchronous belt drive.

[0017] By adopting this technical solution, the roller and calibration plate are fixedly connected to form a rigid contact sensing unit. Any change in slope will directly cause a change in the angle of the calibration plate. The fixed connection between the first rotating shaft and the calibration plate ensures that the angle of the calibration plate is transmitted to the first rotating shaft. The first rotating shaft and the second rotating shaft are connected by a synchronous belt to form a synchronous mechanism with a constant transmission ratio. The second rotating shaft can strictly reproduce the rotation angle of the first rotating shaft, realizing synchronization from the physical tilt of the slope to the laser detection angle, avoiding the delay and error caused by electronic signal conversion and processing.

[0018] Furthermore, two rollers are symmetrically arranged on both sides of the calibration plate.

[0019] By adopting this technical solution, two symmetrical rollers form two contact points with the slope at a fixed distance, which allows the orientation of the calibration plate to more accurately represent the average direction of the slope within the range of the roller span. This effectively filters out interference caused by minor local undulations of the slope, enhances the slope sensing's ability to resist local interference and its overall representativeness, and provides a more reliable input for subsequent precise synchronization.

[0020] This invention also provides a control method for a high-precision road slope laser calibration construction device, comprising the following steps: S1: Positioning step, the contact sensing component of the calibration mechanism is placed on the slope to be measured, and the device adaptively adjusts its attitude under the action of gravity so that the drive wheel contacts the construction road surface; S2: Movement and adaptive adjustment step, controlling the drive wheel to move the device. During this process, the adjustment mechanism adjusts the position of the calibration mechanism according to the terrain changes and buffers the vibration caused by road bumps; S3: Slope synchronization and measurement steps. During the movement, the contact sensing component moves according to the slope inclination and drives the laser detector to deflect synchronously through the transmission component, so that the measurement direction of the laser detector is aligned with the slope in real time and the slope measurement is continuously performed. S4: Feedback and control step, the laser detector sends the measurement data to the external control device, and the external control device generates calibration guidance information based on the deviation between the measurement data and the target slope.

[0021] By adopting this technical solution, the dispersed mechanical functions are integrated into a collaborative and automated work process, which significantly improves the consistency, standardization and efficiency of slope calibration operations.

[0022] Furthermore, in the positioning step S1, preliminary positioning is achieved specifically by the roller contacting the slope surface.

[0023] By adopting this technical solution, the cylindrical structure of the roller facilitates rolling, which helps the device to slide smoothly and level under gravity, reducing the difficulty and time of manual adjustment, and making the initial positioning steps standardized and easy to execute.

[0024] Furthermore, in the slope synchronization and measurement step S3, the rolling of the roller drives the first rotating shaft to rotate through the calibration plate, and then drives the second rotating shaft and the laser detector to rotate synchronously through the synchronous belt or chain.

[0025] By adopting this technical solution, the causal transmission relationship from the physical world to the measurement action is defined, ensuring that the entire synchronization process is a deterministic physical process, thereby guaranteeing the accuracy and reliability of the measurement.

[0026] Compared with the prior art, the present invention has the following advantages: 1. By integrating the adjustment and calibration mechanisms, the device achieves automatic leveling and terrain adaptation, solving the problem of unstable measurement benchmarks. At the same time, it effectively isolates the vibration of the drive unit, significantly improving the measurement stability and accuracy of the laser detector under dynamic movement and complex road conditions.

[0027] 2. Through mechanical contact sensing and synchronous transmission design, the laser detector angle and slope gradient are synchronized without delay and with high fidelity, overcoming the defects of measurement lag or angle asynchrony in the existing technology, and providing real-time and accurate slope data feedback for construction.

[0028] 3. The overall solution has a compact structure and a high degree of automation. It can be integrated into a mobile construction platform to achieve a closed-loop construction process of on-the-go measurement and real-time calibration, which greatly improves the efficiency and quality of road slope construction.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Please see the appendix Figure 1-2 The present invention provides a high-precision road slope laser calibration construction device, including a base 101, and a drive wheel 102 installed on each side of the bottom of the base 101. The drive wheel 102 is an electric wheel that can be driven by a built-in motor and electrically connected to an external control device; the control device is used to send control commands to the drive wheel 102.

[0033] The adjustment mechanism 200 is fixedly installed at the center of the upper surface of the base 101, such as... Figure 2 As shown, the fixing frame of the adjustment mechanism 200 includes a disc-shaped base 201, which is fixedly connected to the upper surface of the base 101 by bolts; on the top surface of the base 201, two cylindrical guide rods 202 are vertically and symmetrically welded and fixed, and these two guide rods 202 are parallel to each other.

[0034] like Figure 3 , Figure 4As shown, the movable support assembly 203 of the adjustment mechanism 200 includes a first sliding seat 2041. The first sliding seat 2041 is generally rectangular in shape, and its bottom is provided with two sliding grooves 2044 that are adapted to the size and shape of the guide rod 202 (e.g., Figure 4 As shown, the first sliding seat 2041 is slidably mounted on the two guide rods 202 through the groove 2044, so that it can slide freely in the vertical direction along the guide rods 202.

[0035] Two sets of support rods 2042 are symmetrically hinged to the outer walls on both sides of the first sliding seat 2041. The support rods 2042 are telescopic structures, such as sleeve cylinders or mechanical telescopic rods with locking functions. The end of each set of support rods 2042 away from the first sliding seat 2041 is hinged to a second connecting seat 2043. The interior of the second connecting seat 2043 has a rectangular cavity, namely a rectangular groove 2045 (e.g., Figure 6 As shown), the top plane of the second connector 2043 serves as the mounting base for the calibration mechanism 300.

[0036] It should be noted that when there are two movable support assemblies 203, the second connecting seat 2043 between the two movable support assemblies 203 is fixedly connected by a connecting plate 2046 (as shown in the attached diagram). Figure 3 (As shown).

[0037] like Figure 5 As shown, the buffer 206 of the adjustment mechanism 200 is installed inside the movable support assembly 203. The buffer 206 includes a mounting base 205, which is rotatably mounted in the rectangular groove 2045 of the second connecting base 2043 via a transverse pivot. A guide rod 2071 is fixedly connected to one outer wall of the mounting base 205, and the axis of the guide rod 2071 is approximately perpendicular to the pivot axis of the mounting base 205.

[0038] A first stop 2072, a spring 2075, a sliding sleeve 2073, and a second stop 2074 are sequentially fitted onto the guide rod 2071. The first stop 2072 is fixedly connected to the rod body of the guide rod 2071; the sliding sleeve 2073 is slidably fitted onto the guide rod 2071; and the second stop 2074 is fixedly connected to the end of the sliding sleeve 2073 facing the spring 2075. The spring 2075 (i.e., the elastic element) is fitted onto the guide rod 2071 and is under pressure. In the pre-tightened state, its two ends are limited and pressed by the first stop 2072 and the second stop 2074 respectively; a connecting rod 2076 is fixedly connected to the end of the sliding sleeve 2073 away from the spring 2075; a third stop 2077 is fixedly provided on the side wall of the first sliding seat 2041, and the bottom end of the third stop 2077 is designed to be arc-shaped; the end of the connecting rod 2076 away from the sliding sleeve 2073 is hinged to the arc-shaped bottom end of the third stop 2077.

[0039] The calibration mechanism 300 is connected to the adjustment mechanism 200 via its mounting bracket 301, such as Figure 1 and Figure 6 As shown, the mounting bracket 301 is L-shaped, and the bottom end of its vertical part is fixedly connected to the center of the top surface of the second connecting seat 2043; the contact sensing component and the transmission component of the calibration mechanism 300 are both mounted on the mounting bracket 301.

[0040] The contact sensing components mainly include a calibration plate 3032 and a roller 3034, such as Figure 6 and Figure 7 As shown, the calibration plate 3032 is a long strip plate, with its middle part fixedly connected to the lower end of a vertically arranged first rotating shaft 3031; the upper end of the first rotating shaft 3031 passes through a through hole opened on the horizontal part (horizontal plate) of the mounting frame 301, and forms a rotatable connection with the mounting frame 301 through a bearing; on the outer sides of both ends of the calibration plate 3032, a connecting block 3033 is symmetrically fixedly connected to each other, and a roller 3034 is rotatably mounted on each connecting block 3033 through a bearing; in this embodiment, the axes of the two rollers 3034 are parallel to the length direction of the calibration plate 3032 and are located on the same horizontal line.

[0041] The transmission component is used to synchronously transmit the motion of the contact sensing component to the laser detector 3038, such as... Figure 8 As shown, a second rotating shaft 3035 is rotatably mounted on the vertical part (vertical plate) of the mounting bracket 301 via bearings. The axis of the second rotating shaft 3035 is parallel to the axis of the first rotating shaft 3031. A synchronous pulley is fixedly mounted on the first rotating shaft 3031 and the second rotating shaft 3035 respectively. A ring-shaped synchronous belt 3036 is tightly fitted on the two synchronous pulleys, thereby drivingly connecting the first rotating shaft 3031 and the second rotating shaft 3035.

[0042] A mounting bracket 3037 is fixedly connected to the end of the second rotating shaft 3035 away from the mounting bracket 301. A laser detector 3038 (e.g., a laser or a laser rangefinder sensor) is fixedly mounted on the mounting bracket 3037. The measuring axis (e.g., the laser line emission plane) of the laser detector 3038 is pre-adjusted to be perpendicular to the axis of the second rotating shaft 3035 or at a preset fixed angle. The laser detector 3038 is also electrically connected to the control device via a cable to send the real-time slope data or position information it detects to the control device for processing. Please refer to the appendix. Figure 9 The control method of the device described in this embodiment of the invention includes the following steps: Step S1 (Positioning Step): The operator places the device beside the road to be constructed, so that the two rollers 3034 at the bottom of the calibration mechanism 300 abut against the shaped or calibrated sloping road surface. The device is released, and under the action of its own weight, the first sliding seat 2041 will slide down along the guide rod 202, and the support rod 2042 will extend accordingly, driving the entire calibration mechanism 300 to move down until the drive wheel 102 at the bottom of the base 101 makes stable contact with the relatively flat main road surface. At this time, the device has completed the initial adaptive attitude adjustment.

[0043] Step S2 (Movement and Adaptive Adjustment Step): The drive wheel 102 is activated by the control device, causing the device to move along the construction road surface at a constant or controlled speed, initiating the continuous slope measurement operation. During the movement, if the relative height between the construction road surface and the slope surface to be measured changes, the first sliding seat 2041 will slide accordingly on the guide rod 202, and the support rod 2042 will automatically extend and retract, thereby dynamically maintaining stable contact between the calibration mechanism 300 (especially the roller 3034) and the slope surface. When the drive wheel 102 encounters... When bumps or potholes on the road surface cause vibrations, the vibrations are transmitted to the first sliding seat 2041 through the base 101, chassis 201 and guide rod 202. The up-and-down vibration of the first sliding seat 2041 pushes or pulls the sliding sleeve 2073 along the guide rod 2071 through the connecting rod 2076, thereby compressing or releasing the spring 2075. The deformation of the spring 2075 absorbs most of the impact energy, so that the second connecting seat 2043 connected to the mounting seat 205 and the entire calibration mechanism 300 remain relatively stable, effectively isolating vibration interference.

[0044] Step S3 (Slope Synchronization and Measurement): As the device moves along the slope, the inclination angle of the slope causes the roller 3034, which is in continuous contact with the slope, to roll. The rolling of the roller 3034 directly drives the calibration plate 3032, which is fixed to it, to rotate around the axis of the first rotating shaft 3031. The rotation of the first rotating shaft 3031 is transmitted through the synchronous belt 3036, which drives the second rotating shaft 3035 to rotate synchronously without delay and proportionally. The second rotating shaft 3035 drives the fixed frame 3037 and the laser detector 3038 mounted on it to deflect synchronously by the same angle. Therefore, the measurement reference (such as the laser plane) of the laser detector 3038 can keep in real time and accurately consistent with the actual slope of the slope. In this state, the laser detector 3038 continues to work, scanning or measuring the slope, and sending the real-time collected accurate slope data to the control device.

[0045] Step S4 (Feedback and Control Step): The processor inside the control device receives real-time data from the laser detector 3038 and compares and calculates it in real time with the preset target slope design value. If there is a deviation between the detected actual slope and the target value, the control device will immediately generate and issue specific calibration guidance information (e.g., "Current location, slope is too steep, needs to be reduced by XX centimeters") through its display screen in graphical or numerical form, or through indicator lights, voice broadcasts, etc. Construction personnel will use tools such as screeds and vibratory tampers to adjust the roadbed or paving materials in real time according to this guidance, thereby achieving dynamic, closed-loop calibration of the slope until the design requirements are met. The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
