Description

[Technical Field]

[0001] This invention belongs to the field of construction technology, and particularly relates to a construction progress monitoring device based on AI algorithms and 3D mapping technology. [Background technology]

[0002] Construction progress monitoring equipment is a dedicated equipment or system that collects, records, and analyzes various progress data from construction sites in real time or periodically, allowing managers to grasp the actual progress of the construction, detect deviations, and assist in decision-making. It usually combines hardware and software to achieve automation, intelligence, and visualization of progress monitoring.

[0003] A search revealed, for example, that a Chinese patent (publication number: CN218992810U) discloses a construction progress monitoring device related to the field of construction technology. The device includes a base, a connecting plate, and a first motor. Mounting bases are connected to both sides of the connecting plate, a rotating block is connected to the mounting base, and a monitor is connected to the rotating block. A second motor is connected to the front of the mounting base, a rotating lever is connected to the second motor, and a gear is connected to the rotating lever. A stopper groove is connected to the bottom of the connecting plate, and a rack is connected to the stopper groove. The rack is connected to an adjustment lever, and the adjustment lever is connected to a connector. This device is equipped with a gear, a rack, and a first motor. The first motor rotates the connecting plate, which in turn rotates the monitor, allowing for multi-angle monitoring. The gear moves the rack left and right, and the rack uses the adjustment lever to rotate the monitor up and down, adjusting its vertical angle, thereby expanding the monitoring range and eliminating blind spots.

[0004] However, this device relies on the meshing of gears and racks to adjust the monitor's vertical angle. Construction sites are often dusty and gravel-filled, and foreign matter can easily get into the meshing surfaces and gaps. Long-term use can cause the gear rack to wear out, reduce meshing accuracy, and even cause jamming, resulting in the monitor no longer being able to adjust the vertical angle or becoming jammed. Therefore, a construction progress monitoring device based on AI algorithms and 3D mapping technology is needed. Summary of the Invention [Problem to be solved by the invention]

[0023] In this embodiment, after activation, the electric telescopic rod 23 moves the connecting ring 22 up and down along the axial direction of the support rod 13, causing the pair of movable plates 21 to also move up and down, synchronously rotating the pair of fixed plates 24 and changing the axial angle between the pair of fixed plates 24, thereby rotating the ends of the pair of monitors 11 and achieving the purpose of adjusting the monitoring range of the monitors 11. In addition, dust and gravel at the construction site will not affect the movement of the movable plate 21 and the rotation of the fixed plate 24, ensuring normal use of the equipment.

[0027] In this embodiment, an operator rotates the rotating lever 33, rotating the gear 32 and moving the rack bar 31 and fixed peg 16 up and down along the locking groove 151, thereby adjusting the device body 1 and expanding the range of application of the device. The rotating lever 33 synchronously rotates the ratchet 36, causing the ratchet lever 34 to rotate around the axis of the mounting post 152. The torsion spring 35 expands and returns to its original position. After the rotation of the rotating lever 33 stops, the elastic force of the torsion spring 35 causes the end of the ratchet lever 34 to engage between adjacent teeth of the ratchet 36. The ratchet 36 and ratchet lever 34 lock the rotating lever 33, ensuring stability after the height adjustment is complete. The operator presses the handle 341 to unlock the ratchet 36 and ratchet lever 34.

[0028] Specifically, the device main body 1 further includes a pair of support links 18 and a pair of sliders 17, the outer wall of the fixed barrel 15 is provided with a pair of opposing slide grooves 153, the upper end of the support link 18 is rotatably mounted on the slider 17, the support link 18 is disposed in the slide groove 153, the side wall of the support link 18 is connected to the inner wall of the slide groove 153 by magnetic attraction, and the slider 17 is slidably engaged with the slide groove 153.

[0029] Specifically, the base 12 is provided with a pair of oppositely arranged horizontal grooves 121, the height adjustment mechanism 3 further includes a pair of abutment blocks 38 and a pair of studs 37, the upper end of the fixed barrel 15 is provided with a pair of oppositely arranged screw holes 154, each abutment block 38 is slidably engaged with its respective horizontal groove 121, the side walls of the abutment blocks 38 are connected to the inner walls of the horizontal grooves 121 by magnetic attraction, the lower end surfaces of the abutment blocks 38 are in the same horizontal plane as the lower end surfaces of the posts on the lower end surface of the base 12, an abutment groove 381 is provided on the upper end surface of the abutment block 38, the lower end of the support link 18 abuts against the abutment groove 381, the stud 37 is threadedly connected to the screw holes 154, and the lower end of the stud 37 is rotatably connected to the upper end surface of the slider 17.

[0030] In this embodiment, after placing the base 12 at the position to be monitored, the operator slides the abutment block 38 out of the horizontal groove 121 to release the magnetic attraction between the abutment block 38 and the side wall of the horizontal groove 121. Then, the operator rotates the stud 37, further moving the slider 17 and the support link 18 down along the slide groove 153, and then rotates the support link 18 out of the slide groove 153 to release the magnetic attraction between the support link 18 and the slide groove 153 and insert the lower end of the support link 18 into the abutment groove 381. In this way, by providing the abutment block 38 and the support link 18, the device body 1 can be placed more stably on the floor, allowing the monitoring process to be performed normally.

[0031] The working principle of this invention is as follows.

[0032] During use, the operator places the base 12 at the position to be monitored, then slides the abutment block 38 out of the horizontal groove 121 to release the magnetic attraction connection between the abutment block 38 and the side wall of the horizontal groove 121, rotates the stud 37, and moves the slider 17 and support link 18 down along the slide groove 153. Then, the operator rotates the support link 18 out of the slide groove 153 to release the magnetic connection between the support link 18 and the slide groove 153, and places the lower end of the support link 18 in the abutment groove 381. In this way, by providing the abutment block 38 and the support link 18, the device main body 1 can be placed more stably on the floor, allowing the monitoring process to be carried out normally.

[0033] Mounting holes are provided on the side wall of the fixed cylinder 15 near the ratchet 36 and ratchet lever 34, and on the upper end near the screw hole 154. Workers fix dust covers to the mounting holes with bolts to prevent debris and gravel from falling into the ratchet 36 and screw hole 154 near the construction site.

[0034] Then, the operator rotates the rotating lever 33, rotates the gear 32, and moves the rack bar 31 and the fixed peg 16 up and down along the locking groove 151, thereby achieving the purpose of adjusting the height of the device body 1 and expanding the application range of the device.

[0035] Furthermore, the ratchet 36 rotates in sync with the rotating lever 33, causing the ratchet lever 34 to rotate axially around the mounting post 152, causing the torsion spring 35 to expand and return to its original position. When the rotation of the rotating lever 33 stops, the elastic force of the torsion spring 35 causes the end of the ratchet lever 34 to engage between adjacent teeth of the ratchet 36. In this way, the provision of the ratchet 36 and ratchet lever 34 achieves a locking effect on the rotating lever 33, ensuring the stability of the equipment after height adjustment is complete. When the operator presses the handle 341, the lock between the ratchet 36 and ratchet lever 34 is released.

[0036] After activation, the electric telescopic rod 23 moves the connecting ring 22 up and down along the axial direction of the support rod 13, causing the pair of movable plates 21 to also move up and down, synchronously rotating the pair of fixed plates 24, changing the axial angle between the pair of fixed plates 24 and rotating the ends of the pair of monitors 11, thereby achieving the purpose of adjusting the monitoring range of the monitors 11. In addition, dust and gravel at the construction site will not affect the movement of the movable plate 21 and the rotation of the fixed plate 24, ensuring normal use of the equipment.

[0037] In addition, a data collection module and a data processing and analysis module are installed inside the Monitor 11, which is connected to external devices via signals, and quickly collects images of the construction site and converts the collected images, point clouds, and other data into a real-life 3D model or digital twin model. This allows the Monitor 11 to automatically collect data from the construction site to generate a 3D model, and uses an AI algorithm to compare models at different time nodes with a pre-set construction plan model to accurately calculate the occupancy rate of the completed area, the completion rate of the construction volume, and other information, intuitively displaying the progress of processes such as earthwork excavation and component installation, while keeping errors low.
