[0001] The present application relates to wall verticality detection technology field, especially to a kind of civil engineering wall verticality detection device. BACKGROUND

[0002] In the field of civil engineering, wall verticality is one of the core indicators to measure the quality of construction engineering, and its precision is directly related to the stability, safety of building structure and the feasibility and aesthetics of subsequent decoration construction. Whether it is residential, commercial building or industrial plant, if the deviation of wall verticality exceeds the allowable range specified in the specification, it may not only cause problems such as difficulty in installing doors and windows, cracking and falling of wall decoration layer, but also seriously affect the stress balance of the overall structure of the building, which may cause safety hazards.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses rollers to drive electromagnetic plates A and B to generate synchronous displacement corresponding to the wall deviation. This displacement is transmitted to the pen via a support rod, causing the drawing trajectory of the pen on the recording board surface to change accordingly. The trajectory deviation directly reflects the verticality of the wall, thus avoiding the problem of interference from external environmental factors such as wind and vibration in the traditional plumb bob detection method.

[0017] 2. In this invention, the frame plate drives the rotating rod to move upward synchronously through the horizontal tube, causing the rotating rod to rotate and drive the swing rod to swing.

[0018] 3. This invention sprays airflow onto the surface of the recording plate through a nozzle, thereby forming a uniform protective air film on the surface of the recording plate using the continuous airflow. This film can block dust and impurities in the external air from remaining in the drawing area of ​​the recording plate, avoiding interference from impurities with the clarity of the drawing lines. It can also accelerate the drying speed of the ink, prevent ink smudging and trailing during the drawing process, and improve the integrity and recognizability of the recorded trajectory.

[0019] 4. In this invention, a portion of the airflow flowing in the exhaust pipe enters the hollow interior of the swing arm through the air supply pipe, causing the air pressure inside the swing arm to gradually increase. The increased air pressure forms a uniform squeezing force on the scraper. Combined with the extension and steering characteristics of the telescopic sleeve, the scraper will adapt and tilt accordingly, thus closely adhering to the inclined surface formed by the protrusion or depression of the wall. This avoids the cleaning failure problem caused by the gap between the scraper and the wall due to changes in the wall contour. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] See Figures 1 to 7 As shown, the present invention provides a wall verticality detection device for civil engineering, including a movable plate 1, a groove 2 is provided at the top of the movable plate 1, a slider 3 driven by a cylinder 4 slides inside the groove 2, a slide rail 5 is fixed at the top of the slider 3, and a threaded rod 11 driven by a motor 12 is rotatably provided inside the slide rail 5. A detection mechanism is slidably provided on one side of the slide rail 5. The detection mechanism includes a frame plate 61 threadedly connected to the outer wall of the threaded rod 11. A sleeve 64 is fixedly fixed inside the frame plate 61. A slide rod 65 slides inside the sleeve 64. A bracket 66 is fixed to one end of the slide rod 65. A roller 67 is rotatably provided inside the bracket 66. An electromagnetic plate B69 is fixed to the other end of the slide rod 65. A first spring is fixed to the inner wall of the frame plate 61. An electromagnetic plate A62 is fixed to one end of the first spring. A support rod 612 is fixed to the side wall of the electromagnetic plate A62. A clamp 613 is fixed to one end of the support rod 612. A pen 614 is installed inside the clamp 613. A magnetic block 610 is fixed to the side wall of the slide rail 5. A recording plate 611 is magnetically connected to one side of the magnetic block 610. A second spring is provided inside the sleeve 64. It should be noted that when the verticality of the wall needs to be tested, the operator first moves the device to the area of ​​the wall to be tested, so that the side of the moving plate 1 is parallel to the wall. After positioning, the operator activates the cylinder 4. The telescopic end of the cylinder 4 drives the slider 3 to slide along the groove 2 opened at the top of the moving plate 1. The movement of the slider 3 simultaneously drives the slide rail 5 to move, which in turn causes the roller 67 on one side of the upper frame plate 61 of the slide rail 5 to gradually approach and fit against the wall. Under the continuous driving force of the cylinder 4, the roller 67 contacts the wall. When compressed, this compressive force is transmitted to the slide rod 65 through the mounting carrier bracket 66 of the roller 67, causing the slide rod 65 to slide axially along the inside of the sleeve 64 fixed on the frame plate 61. At this time, the second spring sleeved on the outside of the slide rod 65 is compressed and generates stored force. At the same time, the slide rod 65 drives the electromagnetic plate B69 to move towards the electromagnetic plate A62 on the inner wall side of the frame plate 61. When the electromagnetic plate A62 and the electromagnetic plate B69 are completely in contact, it indicates that the roller 67 has reached the optimal contact pressure with the wall. The staff then closes the cylinder 4 to complete the preparation work before the test. After the testing phase begins, the operator turns on motor 12. The output of motor 12 drives the threaded rod 11 inside the slide rail 5 to rotate. Since the frame plate 61 and the threaded rod 11 are threadedly connected, the rotational motion of the threaded rod 11 is converted into the vertical upward movement of the frame plate 61 along the axis of the slide rail 5. The movement of the frame plate 61 synchronously drives the roller 67 to perform rolling testing along the wall. During this process, the frame plate 61 will drive the electromagnetic plate A62 to move synchronously. The electromagnetic plate A62 drives the clamp 613 and the pen 614 installed in the clamp 613 to move through the support rod 612. The pen 614 then draws a reference line on the surface of the recording plate 611, which is attached and fixed by the magnetic block 610 on the side wall of the slide rail 5. When there is a verticality deviation such as a convex or concave surface on the wall, the change in the contour of the wall will push or pull the roller 67 to produce The displacement is transmitted to the electromagnetic plate B69 via the bracket 66 and the slide rod 65, which in turn drives the electromagnetic plate A62 to generate a synchronous displacement corresponding to the wall deviation. This displacement is transmitted to the pen 614 via the support rod 612, causing the drawing trajectory of the pen 614 on the surface of the recording plate 611 to change accordingly. The trajectory deviation directly reflects the verticality of the wall, thus avoiding the problem of interference from external environmental factors such as wind and vibration in the traditional plumb line test method. This ensures the stability of the test process and the accuracy of the test results. At the same time, the test and recording are synchronized and integrated. The perception of the wall deviation by the roller 67 can be converted into the trajectory change of the pen 614 in real time. There is no need for the staff to manually record or read data during the test, which simplifies the test process and improves the efficiency of the test operation.

[0024] The roller 67 is provided with a scraping mechanism on both sides. The scraping mechanism includes a rotating rod 71 that rotates on both sides of the bracket 66. One end of the rotating rod 71 is fixed with a swing rod 72. One side of the swing rod 72 is fixed with a telescopic sleeve 73. One side of the telescopic sleeve 73 is fixed with a scraper 77. It should be noted that as the frame plate 61 moves upward, it drives the rotating rod 71 to move upward synchronously via the horizontal tube 89. The rotating rod 71 then drives the gear 76 at its end to move upward synchronously along the inside of the housing 74 fixed to the side wall of the slide rail 5. Since the gear 76 meshes with the rack 75 on the inner wall of the housing 74, the gear 76 will rotate intermittently along the surface of the rack 75 as it moves upward with the rotating rod 71, thereby driving the rotating rod 71 to rotate synchronously. The rotation of the rotating rod 71 then drives the swing rod 72 to swing outward along the forward path of the roller 67. At this time, the swing rod 72 is connected to the rotating rod 71. The torsion spring at the location is twisted and stores force. When the gear 76 moves to the segment gap of the rack 75 and disengages from the teeth of the rack 75, the torsion spring instantly releases the torque, causing the rotating rod 71 to rotate in the opposite direction. This causes the swing rod 72 and the scraper 77 on the swing rod 72 to quickly return to their original positions. This cycle repeats, allowing the swing rod 72 to drive the scraper 77 to swing back and forth along the wall. The scraper 77 scrapes away dust, laitance, and other impurities on the rolling path of the roller 67 to both sides, thus preventing impurities from adhering to the surface of the roller 67 and interfering with subsequent testing. This reduces testing errors and ensures the accuracy of the testing work.

[0025] The top of the scraper 77 is equipped with a cleaning mechanism.

[0026] In an optional embodiment, one end of the second spring is fixedly connected to the inner wall of the sleeve 64, and the other end of the second spring is fixedly connected to one end of the slide rod 65. When the detection front roller 67 is in contact with the wall, the slide rod 65 is pressed to push the second spring to compress and store force, providing a stable contact pressure for the roller 67 and ensuring the reliability of the detection benchmark. When there are protrusions or depressions on the wall, the second spring adapts to the expansion and contraction of the slide rod 65, transmitting the signal of wall contour change and ensuring the accuracy of the pen 614 in recording deviations.

[0027] In an optional embodiment, a housing 74 is fixed to the side wall of the slide rail 5, a rack 75 is fixed to the inner wall of the housing 74, and a gear 76 is fixed to one end of the rotating rod 71 located inside the housing 74. The rack 75 and the gear 76 mesh with each other, and the rack 75 is segmented.

[0028] In an optional embodiment, the rotating rod 71 is telescopic, with one end of the rotating rod 71 fixed to the swing rod 72 being the telescopic end and the other end of the rotating rod 71 being the fixed end, and the telescopic end being embedded inside the fixed end. The telescopic configuration of the rotating rod 71 adapts to the displacement generated by the roller 67.

[0029] In an optional embodiment, the cleaning mechanism includes horizontal tubes 89 fixed on both sides of the frame plate 61, a rotating rod 71 rotating inside the horizontal tubes 89 via bearings, a threaded section on the outer wall of the rotating rod 71, a piston 81 threadedly connected to the outer wall of the rotating rod 71, a collection box 82 fixed on one side of the swing rod 72, a suction pipe 83 connected to one side of the collection box 82, a negative pressure pipe 84 connected between the horizontal tubes 89 and the collection box 82, and a filter screen provided at the connection port between the negative pressure pipe 84 and the collection box 82.

[0030] In an optional embodiment, the cleaning mechanism further includes an air intake pipe 85 connected to the outer wall of the horizontal tube 89, a diversion pipe 87 fixed to the side wall of the piston 81, a nozzle 88 connected to one end of the negative pressure pipe 84, an exhaust pipe 86 connected between the horizontal tube 89 and the diversion pipe 87, the nozzle 88 facing the surface of the recording plate 611, a connecting pipe fixed between the horizontal tubes 89, and an adjustment mechanism provided on one side of the horizontal tube 89.

[0031] It should be noted that when the frame plate 61 moves upward along the slide rail 5, it drives the rotating rod 71 to move upward synchronously through the horizontal tube 89. The gear 76 at one end of the rotating rod 71 meshes with the rack 75 in the housing 74 to produce intermittent rotation, which in turn drives the swing rod 72 to rotate outward. During this process, the rotating rod 71 drives the piston 81 inside the horizontal tube 89 to move along the tube cavity, which increases the volume of the right chamber of the horizontal tube 89 and forms a negative pressure. This negative pressure is transmitted to the collection box 82 on one side of the swing rod 72 through the connected negative pressure pipe 84, causing the dust suction pipe 83 on the collection box 82 to generate suction force, and sucking the wall impurities just scraped off by the scraper 77 into the collection box 82 in time, avoiding the impurities from scattering and flying, realizing the immediate collection of impurities, solving the problem of dust flying and polluting the testing environment during cleaning, preventing suspended impurities from being inhaled by the staff, ensuring the health of the staff, and also preventing the scattered impurities from adhering to the wall or roller 67 again, further ensuring the stability of the testing benchmark. When gear 76 disengages from the teeth of rack 75, the torsion spring releases torque, causing the rotating rod 71 to rotate in the opposite direction. The rocker arm 72 begins to reset. At this time, piston 81 moves towards the side closer to gear 76, compressing the gas in the left chamber of the horizontal tube 89. When the rocker arm 72 completes its reset and rotates outward again, piston 81 compresses the gas in the right chamber of the horizontal tube 89, allowing the gas to enter the exhaust pipe 86 through the connecting pipe. Simultaneously, one-way valves are installed in the negative pressure pipe 84, intake pipe 85, connecting pipe, and exhaust pipe 86 to ensure unidirectional airflow. This cycle ensures that the gas in the horizontal tube 89 continuously enters the diversion pipe 87 through the exhaust pipe 86, and the airflow within the diversion pipe 87... After being split, the airflow enters evenly into nozzle 88, which sprays the airflow onto the surface of the recording plate 611 and acts on the tip of the pen 614. The continuous airflow sprayed onto the surface of the recording plate 611 forms a uniform protective air film, which can block dust and impurities in the outside air from remaining in the drawing area of ​​the recording plate 611, thus avoiding interference with the clarity of the drawing. The airflow acting on the tip of the pen 614 can not only blow away the tiny impurities attached to the tip in time, but also accelerate the drying speed of the ink, prevent ink smudging and trailing during the drawing process, and improve the integrity and recognizability of the recorded trajectory.

[0032] In an optional embodiment, the control mechanism includes an air supply pipe 91 connected to one side of the horizontal pipe 89, one end of the air supply pipe 91 being connected to the interior of the rocker arm 72, an adjusting valve 92 being installed on the outer wall of the air supply pipe 91, a valve stem 93 being rotatably mounted on the outer wall of the adjusting valve 92, and a rack rod 94 that meshes with the valve stem 93 being fixed at the top of the frame plate 61.

[0033] In an optional embodiment, the section connecting the gas supply pipe 91 and the exhaust pipe 86 is a rigid pipe, and the section connecting the gas supply pipe 91 and the swing rod 72 is a flexible pipe.

[0034] It should be noted that when the wall contour changes, pushing or pulling the roller 67 to produce displacement, the roller 67 drives the slide rod 65 to move along the sleeve 64 through the bracket 66. The slide rod 65 then drives the electromagnetic plate B69 and electromagnetic plate A62 to move synchronously. The displacement of electromagnetic plate A62 drives the rack rod 94 to move together. Since the rack rod 94 and the valve stem 93 of the regulating valve 92 mesh with each other, the rack rod 94 drives the valve stem 93 to rotate, causing the regulating valve 92, which was originally in a sealed state, to switch to an open state. At this time, part of the airflow flowing in the exhaust pipe 86 enters the hollow interior of the swing rod 72 through the air supply pipe 91, causing the air pressure inside the swing rod 72 to gradually increase. The increased air pressure forms a uniform squeezing force on the scraper 77. With the extension and steering characteristics of the telescopic sleeve 73, the scraper 77 will produce an adaptive tilt, thus closely fitting the inclined surface formed by the protrusion or depression of the wall, avoiding the cleaning failure problem caused by the gap between the scraper 77 and the wall due to the change of the wall contour.

[0035] In an optional embodiment, the swing arm 72 has a hollow structure inside, and a pressure relief valve is installed inside the swing arm 72. When the detection mechanism moves to a flat area of ​​the wall, the roller 67 resets, causing the slide bar 65, the electromagnetic plate A62, and the rack 94 to return to their initial positions. The rack 94 drives the valve stem 93 to rotate in the opposite direction, causing the regulating valve 92 to close, and the airflow stops entering the swing arm 72. Under the reset elastic force of the telescopic sleeve 73, the scraper 77 is pulled back to its initial state. During the reset process, the scraper 77 squeezes the residual gas inside the swing arm 72, and the excess gas is safely discharged through the pressure relief valve on the swing arm 72, ensuring that the internal air pressure of the swing arm 72 returns to normal, and preparing for the next adaptive adjustment.

[0036] In an optional embodiment, a torsion spring is fitted on the outer wall of the rotating rod 71, with one end of the torsion spring fixed to one end of the swing rod 72 and the other end of the torsion spring fixed to one side of the bracket 66.

[0037] Working principle: When a wall needs to be tested for verticality, the operator first moves the device to the area of ​​the wall to be tested, ensuring that the side of the moving plate 1 is parallel to the wall. After positioning, the operator activates the cylinder 4. The telescopic end of the cylinder 4 drives the slider 3 to slide along the groove 2 at the top of the moving plate 1. The movement of the slider 3 synchronously drives the slide rail 5 to move, causing the roller 67 on one side of the upper frame plate 61 of the slide rail 5 to gradually approach and conform to the wall. Under the continuous driving force of the cylinder 4, the roller 67 is subjected to force after contacting the wall. When the roller 67 is compressed, the extrusion force is transmitted to the slide rod 65 through the mounting carrier bracket 66 of the roller 67, causing the slide rod 65 to slide axially along the inside of the sleeve 64 fixed on the frame plate 61. At this time, the second spring sleeved on the outside of the slide rod 65 is compressed and generates stored force. At the same time, the slide rod 65 drives the electromagnetic plate B69 to move towards the electromagnetic plate A62 on the inner wall side of the frame plate 61. When the electromagnetic plate A62 and the electromagnetic plate B69 are completely in contact, it indicates that the roller 67 has reached the optimal contact pressure with the wall. The staff then closes the cylinder 4 to complete the preparation work before the test. After the testing phase begins, the operator turns on motor 12. The output of motor 12 drives the threaded rod 11 inside the slide rail 5 to rotate. The rotational motion of the threaded rod 11 is converted into the vertical upward movement of frame plate 61 along the axis of slide rail 5. The movement of frame plate 61 synchronously drives roller 67 to perform rolling testing along the wall. During this process, frame plate 61 drives electromagnetic plate A62 to move synchronously. Electromagnetic plate A62 drives clamp 613 and the pen 614 installed in clamp 613 to move through support rod 612. The pen 614 is located on the side of slide rail 5. The wall magnet 610 is used to adsorb and fix the recording plate 611 surface for reference drawing. When there is a verticality deviation such as a convex or concave surface on the wall, the change in the contour of the wall will push or pull the roller 67 to produce displacement. This displacement is transmitted to the electromagnetic plate B69 through the bracket 66 and the slide rod 65, which in turn drives the electromagnetic plate A62 to produce a synchronous displacement corresponding to the wall deviation. This displacement is transmitted to the pen 614 through the support rod 612, so that the drawing trajectory of the pen 614 on the surface of the recording plate 611 changes accordingly. The verticality of the wall is reflected intuitively through the trajectory deviation. As the frame plate 61 moves upward, it drives the rotating rod 71 to move upward synchronously via the horizontal tube 89. The rotating rod 71 then drives the gear 76 at its end to move upward synchronously along the inside of the housing 74 fixed to the side wall of the slide rail 5. Since the gear 76 meshes with the rack 75 on the inner wall of the housing 74, the gear 76 will intermittently rotate along the surface of the rack 75 as it moves upward with the rotating rod 71, thereby driving the rotating rod 71 to rotate synchronously. The rotation of the rotating rod 71 then drives the swing rod 72 to move along the front of the roller 67. The path swings outward. At this time, the torsion spring at the connection between the swing rod 72 and the rotating rod 71 is twisted and stores power. When the gear 76 moves to the segment gap of the rack 75 and disengages from the teeth of the rack 75, the torsion spring releases the torque instantly, causing the rotating rod 71 to rotate in the opposite direction, so that the swing rod 72 and the scraper 77 on the swing rod 72 quickly return to their original positions. This cycle repeats to achieve the swing rod 72 driving the scraper 77 to swing back and forth along the wall. The scraper 77 is used to scrape and clean the dust, slurry and other impurities on the rolling path of the roller 67 to both sides. When the frame plate 61 moves upward along the slide rail 5, it drives the rotating rod 71 to move upward synchronously through the horizontal tube 89. The gear 76 at one end of the rotating rod 71 meshes with the rack 75 in the housing 74 to produce intermittent rotation, which in turn drives the swing rod 72 to rotate outward. During this process, the rotating rod 71 drives the piston 81 inside the horizontal tube 89 to move along the tube cavity, which increases the volume of the right chamber of the horizontal tube 89 and forms a negative pressure. This negative pressure is transmitted to the collection box 82 on one side of the swing rod 72 through the connected negative pressure pipe 84, which causes the suction pipe 83 on the collection box 82 to generate suction force, and sucks the wall impurities that the scraper 77 just scraped off into the collection box 82 in time, avoiding the impurities from scattering and flying, and realizing the immediate collection of impurities. When gear 76 disengages from the teeth of rack 75, the torsion spring releases torque, causing the rotating rod 71 to rotate in the opposite direction. The rocker arm 72 begins to reset. At this time, the piston 81 moves to the side closer to gear 76, squeezing the gas in the left chamber of the horizontal tube 89. When the rocker arm 72 completes its reset and rotates outward again, the piston 81 squeezes the gas in the right chamber of the horizontal tube 89, allowing the gas to enter the exhaust pipe 86 through the connecting pipe. This cycle allows the gas in the horizontal tube 89 to continuously enter the diversion pipe 87 through the exhaust pipe 86. After the airflow is diverted in the diversion pipe 87, it enters the nozzle 88 evenly. The nozzle 88 sprays the airflow onto the surface of the recording plate 611 and acts on the tip of the pen 614. When the wall contour changes, pushing or pulling the roller 67 to produce displacement, the roller 67 drives the slide rod 65 to move along the sleeve 64 through the bracket 66. The slide rod 65 then drives the electromagnetic plate B69 and electromagnetic plate A62 to move synchronously. The displacement of electromagnetic plate A62 drives the rack rod 94 to move together. Since the rack rod 94 and the valve stem 93 of the regulating valve 92 mesh with each other, the rack rod 94 drives the valve stem 93 to rotate, causing the regulating valve 92, which was originally in a sealed state, to switch to an open state. At this time, part of the airflow flowing in the exhaust pipe 86 enters the hollow interior of the swing rod 72 through the air supply pipe 91, causing the air pressure inside the swing rod 72 to gradually increase. The increased air pressure forms a uniform squeezing force on the scraper 77. With the extension and steering characteristics of the telescopic sleeve 73, the scraper 77 will produce an adaptive tilt.
