DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Reference below Figure 1-Figure 6The invention describes an intelligent device and method for highly efficient control of crack resistance and flatness of a large-area horizontal structure according to an embodiment of the invention.

[0028] On the one hand, referring to Figure 1-Figure 3 The present invention provides an intelligent device for high-efficiency control of crack resistance and flatness of a large-area horizontal structure, comprising: a guide mechanism 1, a driving mechanism 2, and a detection mechanism 3. The guide mechanism 1 is arranged along a first direction of the horizontal structure, and two guide mechanisms 1 are arranged at intervals along a second direction of the horizontal structure, and the first direction and the second direction are perpendicular to each other. The driving mechanism 2 is arranged on the guide mechanism 1, and the driving mechanism 2 is connected to the detection mechanism 3 and is used to drive the detection mechanism 3 to move along the first direction. The detection mechanism 3 is driven by the driving mechanism 2 to move along the first direction to detect the flatness of the surface to be tested of the horizontal structure.

[0029] The first direction may be the length direction of the horizontal structure or the width direction of the horizontal structure. In this embodiment, the first direction is defined as the length direction of the horizontal structure, and the second direction is the width direction of the horizontal structure. By arranging the guide mechanism 1 along the length direction of the horizontal structure, the detection mechanism 3 can be driven to perform detection along the length direction of the horizontal structure.

[0030] The detection mechanism 3 includes: a frame 31, a telescopic assembly 32 and a pressure detection member 33. The two ends of the frame 31 are respectively mounted on the two guide mechanisms 1. One end of the telescopic assembly 32 is connected to the frame 31, and the other end of the telescopic assembly 32 is rotatably provided with a roller 5 that abuts against the horizontal structure surface. The pressure detection member 33 is connected to the telescopic assembly 32 through a transmission member 34, and the pressure detection member 33 is used to detect the pressure value generated when the telescopic assembly 32 is extended.

[0031] After confirming that the guide mechanism 1, the driving mechanism 2 and the detection mechanism 3 have been correctly installed and calibrated, the detection mechanism 3 is driven by the driving mechanism 2 to move along the guide mechanism 1 in the first direction. During the movement of the detection mechanism 3, the telescopic component 32 will automatically extend and retract according to the unevenness of the horizontal structure surface to keep the roller 5 in continuous contact with the surface to be tested of the horizontal structure. Through the cooperation between the telescopic component 32 and the pressure detection component 33, the pressure detection component 33 monitors the pressure changes when the telescopic component 32 is extended and retracted in real time, and records the pressure data and compares it with the initial pressure standard value, which is conducive to accurately detecting small changes on the surface of the horizontal structure. The pressure detection component 33 can provide instant feedback information, which improves the flexibility of detection.

[0032] Reference Figure 1-Figure 4According to some embodiments of the present invention, the telescopic assembly 32 includes: a hinge structure 321 and a telescopic member 322 forming a parallelogram, the top of the hinge structure 321 is connected to the frame 31, the bottom of the hinge structure 321 is connected to the roller 5, one end of the telescopic member 322 is hinged to the side of the hinge structure 321, and the other end of the telescopic member 322 is hinged to the top of the hinge structure 321. The hinge structure 321 in the shape of a parallelogram refers to a parallelogram formed by four rods being hinged in sequence, and the four hinge points are connected by a line.

[0033] When the detection mechanism 3 moves along the guide mechanism 1, if it encounters a protrusion or depression on the surface of the horizontal structure, the roller 5 will be subjected to a force in the vertical direction. Since the roller 5 is connected by the hinge structure 321, it can move up and down freely under the action of these forces. When the roller 5 moves upward (for example, encountering a protrusion), the bottom of the hinge structure 321 will be lifted upward, while the top is relatively fixed. At this time, the telescopic member 322 will be compressed. On the contrary, when the roller 5 moves downward (for example, encountering a depression), the bottom of the hinge structure 321 will sink. At this time, the telescopic member 322 will stretch. The compression or extension of the telescopic member 322 will be transmitted to the pressure detection member 33 through the transmission member 34, and the change of the pressure value will be detected by the pressure detection member 33, so that the flatness of the surface to be tested of the horizontal structure can be judged.

[0034] In some specific examples, the hinged structure 321 includes a top frame 3211, two side frames 3212 and a bottom frame 3213. The top frame 3211 is connected to the frame 31 and maintains a horizontal extension state. The bottom frame 3213 includes two rods connected at the lower ends, and the upper ends of the two rods are far away from each other to form a V-shaped structure, and the opening of the V faces upward. The tops of the two side frames 3212 are hinged to the lower end surface of the top frame 3211, and the two side frames 3212 are parallel to each other. The bottoms of the two side frames 3212 are respectively hinged to the two ends of the V of the bottom frame 3213, and the roller 5 is hinged to the bottom of the V. When the pressure value detected by the pressure detection member 33 is a standard value, the two side frames 3212 are tilted from top to bottom toward the front of the frame 31. The front of the frame 31 is the front of the detection direction. For ease of understanding, the front and rear of the frame 31 are used as references for subsequent descriptions. When encountering a larger protruding obstacle, the setting of the hinge structure 321 can make the roller 5 lift up to the rear of the frame 31 to form a folded state to improve the protection of the overall structure. In another example, a hook is fixed on the lower end surface of the top frame 3211 and located between the two side frames 3212, and a corresponding hanging rod is set on the side frame 3212 located in front of the frame 31. The opening of the hook faces the rear of the frame 31, and the hanging rod is close to the top of the side frame 3212 and can cooperate with the hook. When encountering a position where no detection is required, such as a curb, the bottom of the detection mechanism 3 can be folded to improve the protection of the roller 5.

[0035] Reference Figure 3-Figure 4 According to some embodiments of the present invention, the telescopic member 322 includes: a telescopic cylinder 3221, a telescopic piston 3222, and a telescopic rod 3223. The telescopic cylinder 3221 has a telescopic cavity, and one end of the telescopic cylinder 3221 is hinged to the top of the hinge structure 321. The telescopic piston 3222 is slidably connected in the telescopic cavity. One end of the telescopic rod 3223 is hinged to the side of the hinge structure 321, and the other end of the telescopic rod 3223 is inserted into the telescopic cylinder 3221 and connected to one end of the telescopic piston 3222.

[0036] One end of the telescopic member 322 is hinged to the top of the hinge structure 321, and the other end is hinged to the side of the hinge structure 321. When the roller 5 contacts the uneven surface of the horizontal structure, the telescopic member 322 can adapt to the telescopic movement of the hinge structure 321. That is, when the bottom of the hinge structure 321 rises, the bottom of the side of the hinge structure 321 is driven to lift upward, so that the telescopic rod 3223 contracts along the telescopic cylinder 3221, driving the telescopic piston 3222 to slide along the telescopic cavity toward the top of the telescopic cylinder 3221, and squeezing the medium in the telescopic cavity; when the bottom of the hinge structure 321 is unfolded downward, the side of the hinge structure 321 is driven to extend downward, pulling the telescopic rod 3223 to slide along the telescopic cavity toward the top of the telescopic cylinder 3221.

[0037] In some specific examples, the telescopic member 322 is located on one side of the hinge structure 321 in the second direction, and is staggered with the hinge structure 321 to avoid interference between the hinge structure 321 and the telescopic member 322 when the hinge structure 321 is lifted or lowered. One end of the telescopic rod 3223 is hinged to the side frame 3212 near the front of the frame 31, and the hinge point between the telescopic rod 3223 and the side frame 3212 is near the lower end of the side frame 3212, and the upper end of the telescopic cylinder 3221 is hinged to the top frame 3211 near the rear of the frame 31, so that the telescopic member 322 is tilted from bottom to top toward the direction near the rear of the frame 31.

[0038] Reference Figure 3-Figure 4 According to some embodiments of the present invention, the transmission member 34 includes: a transmission cylinder 341, a transmission piston 342, and a connecting pipe 343. The transmission cylinder 341 has a transmission cavity, the transmission cylinder 341 is arranged on the frame 31, the transmission piston 342 is slidably arranged in the transmission cavity, one end of the connecting pipe 343 is connected to one end of the transmission cavity, and the other end of the connecting pipe 343 is connected to one end of the telescopic cavity. The connecting pipe 343 can be an elastic tube.

[0039] According to some embodiments of the present invention, the transmission piston 342 divides the transmission chamber into a first chamber and a second chamber, the first chamber is connected to the connecting pipe 343, the pressure detection component 33 is a pressure sensor and is connected to the second chamber, and the pressure detection component 33 is used to detect the pressure value in the second chamber.

[0040] Specifically, the telescopic cavity can also be divided into a third cavity and a fourth cavity by the telescopic piston 3222. The third cavity is a cavity in the telescopic cavity and the telescopic piston 3222 is connected to the telescopic rod 3223. The fourth cavity is in the telescopic cavity and is located on the side of the telescopic piston 3222 away from the telescopic rod 3223. The telescopic cavity and the side of the telescopic piston 3222 away from the telescopic rod 3223 can be filled with a medium, which can be a liquid or a gas, that is, the fourth cavity is filled with a medium, and the medium can be transferred in the first cavity and the fourth cavity through the connecting tube 343.

[0041] If the roller 5 encounters a protrusion, the bottom of the hinged structure 321 will lift up, and the telescopic rod 3223, under the action of the hinged structure 321, drives the telescopic piston 3222 to slide along the telescopic cavity toward the fourth cavity, thereby reducing the volume inside the fourth cavity. Since the connecting tube 343 connects the fourth cavity and the first cavity, the transmission piston 342 moves along the transmission cavity toward the second cavity, thereby reducing the volume of the second cavity and increasing its internal pressure. Since the pressure sensor is connected to the second cavity, the pressure of the second cavity can be detected.

[0042] On the contrary, if the roller 5 encounters a depression, the bottom of the hinged structure 321 extends downward, pulling the telescopic rod 3223, and driving the telescopic piston 3222 to slide along the telescopic cavity toward the third cavity, thereby increasing the volume of the fourth cavity, and then driving the transmission piston 342 to move along the transmission cavity toward the first cavity, thereby increasing the volume of the second cavity and reducing its internal pressure.

[0043] The system can determine the flatness of the horizontal structure and whether there are potential crack problems based on the pressure changes. Specifically, by electrically connecting the pressure sensor to the control module, the pressure data measured by the pressure sensor can be recorded and analyzed.

In some examples, the length of the connecting tube 343 is long, so that when the distance between the frame 31 and the telescopic assembly 32 is increased, the connection between the connecting tube 343 and the telescopic member 322 and the transmission member 34 is not affected.

When the adjustment sleeve 361 is clamped on the support rod 311, the contact area is larger and the installation is more stable. The adjustment rod 362 is located below the frame 31, and the two ends of the adjustment rod 362 are respectively fixed to the adjustment sleeves 361 on the two support rods 311.

[0063] On the other hand, referring to Figure 1-Figure 6 The present invention also proposes a construction method of an intelligent device for efficiently controlling the anti-cracking and flatness of a large-area horizontal structure, including an intelligent device for efficiently controlling the anti-cracking and flatness of a large-area horizontal structure according to any of the above-mentioned embodiments, and the construction method includes the following steps.

[0064] S1. Establish positioning reference.

[0065] Four-point positioning is performed on the surface to be measured of the horizontal structure, positioning piles are installed at the four corners of the surface to be measured, and positioning lines are connected between adjacent positioning piles so that the four positioning lines are on the same horizontal plane and serve as the positioning surface.

[0066] S2. Install the equipment and calibrate it.

[0067] The equipment is installed on the surface to be tested and calibrated according to the positioning surface. The testing equipment is installed to ensure that the roller 5 can rotate freely and contact the surface to be tested well. A testing reference surface 41 is established and it is ensured that the roller 5 can contact the testing reference surface 41. The pressure testing component 33 is adjusted so that the pressure value measured by the pressure testing component 33 is a standard value.

[0068] S3. Start detection.

[0069] Start the detection process, and drive the detection mechanism 3 to move along the first direction through the driving mechanism 2. During this process, the telescopic component 32 will automatically extend and retract according to the unevenness of the surface to be tested to maintain continuous contact between the roller 5 and the surface to be tested. The pressure detection component 33 detects the surface flatness of the surface to be tested in real time to record the pressure data and transmit it to the control module.

[0070] S4. Collect data and process and analyze them.

[0071] The collected pressure data is analyzed and processed to indicate which parts of the horizontal structure may have flatness problems or potential cracks and the results are output through the control module.

[0072] S5. Re-examination.

[0073] After completing the above steps, you can repeat the above steps for re-inspection.

[0074] According to some embodiments of the present invention, the detection can be repeated multiple times in the detection process. For example, in the first direction along the horizontal structure, the detection mechanism 3 can be driven forward by the driving mechanism 2 to detect the surface to be tested from one end of the guide rail 12 to the other end, and then the detection mechanism 3 can be driven back by the driving mechanism 2 to detect the surface to be tested from the other end of the guide rail 12 to one end of the guide rail 12. The results of the two tests can be compared. After the two tests, the position of the adjustment part 36 relative to the support rod 311 can be adjusted so that the multiple telescopic components 32 are synchronously moved to the left or right by a fixed value, and then the multiple adjustment parts 36 are fixed, and the above steps are repeated to detect the surface of the horizontal structure twice.

[0075] In other examples, after two inspections, the guide mechanism 1 may be reinstalled so that the guide mechanism 1 is arranged along the second direction, and the entire device may be adjusted accordingly, and the operation may be repeated starting from step S2 to perform inspection in another direction.

[0076] In some other examples, when the guide mechanism 1 is arranged along the second direction, after repeating steps S2-S5, the position of the adjusting part 36 relative to the support rod 311 is adjusted so that the multiple telescopic components 32 are synchronously moved to the left or right by a fixed value, and then the multiple adjusting parts 36 are fixed, and the above steps are repeated to detect the surface of the horizontal structure twice.

[0077] In addition, during the detection process, the detection mechanism 3 is driven forward by the driving mechanism 2 to move from one end of the guide rail 12 to the other end of the guide rail 12 to detect the surface to be tested once; by adjusting the adjustment part 36 to move a fixed value to the left or right relative to the support rod 311, and then fixing multiple adjustment parts 36, the detection mechanism 3 is driven back by the driving mechanism 2 to detect the surface of the horizontal structure.

[0078] In addition, multiple camera assemblies can be installed on the frame 31. During the movement of the frame 31, the camera assemblies are electrically connected to the control module of the system in combination with the images captured by the camera assemblies. When the detection mechanism 3 detects a change in the pressure value, the camera assemblies can be used to verify the results measured by the detection mechanism 3 to improve the detection efficiency and accuracy.
