Description

Technical Field

[0001] This invention relates to the field of building inspection equipment technology, and in particular to a building tilt warning device and its warning method for building inspection. Background Technology

[0002] In the entire construction process, routine maintenance, and safety inspection of old buildings, building tilt detection is a core and critical link in ensuring the stability of building structures and the safety of people. Building tilt is often caused by factors such as foundation settlement, structural aging, and external forces. If it is not detected and warned in a timely and accurate manner, the tilt problem may continue to worsen, leading to serious safety accidents such as wall cracking, structural instability, or even collapse, causing incalculable losses to life and property.

[0003] Current building tilt detection equipment has a fixed detection height, making it difficult to flexibly adjust according to the height requirements of different detection locations on the building. This results in a limited detection range. In addition, the installation and fixation of the detection equipment are not stable enough, and it is easy to shift during the detection process, which affects the detection accuracy and fails to meet the detection requirements.

[0004] Therefore, this application proposes a building tilt warning device and warning method for building inspection to solve the above problems. Summary of the Invention

[0005] Therefore, in view of the above problems, the present invention proposes a building tilt warning device and warning method for building inspection, which solves the above technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A building tilt warning device for building inspection includes a conveying trolley and a base. A servo cylinder is fixedly connected to the top of the conveying trolley to drive the base to move vertically up and down. Telescopic guide devices are fixedly connected to the four corners of the top of the conveying trolley to guide the vertical movement of the base. The output end of the servo cylinder and the telescopic end of the telescopic guide device are both fixedly connected to the base. A horizontally distributed slide groove is opened on the top of the base, and a base is slidably connected in the slide groove. A sensor device for detecting the tilt of the building is installed on the base. A warning component for external warning is fixedly connected to the top of the conveying trolley. Adjustable foot pads with adjustable support height are fixedly connected to the four corners of the bottom of the conveying trolley. A moving platform is provided at the bottom of the adjustable foot pad. An extension plate is provided on one side of the base. A rotary drive device for driving the extension plate to rotate is provided on one side of the conveying trolley. A transverse groove for docking with the slide groove is provided on the two sides of the top surface of the extension plate.

[0008] The mobile platform is equipped with a cleaning device located below the extension plate. The cleaning device includes a cleaning frame on the mobile platform, a longitudinal axis drive platform on the cleaning frame for longitudinal movement, a drive cylinder on the longitudinal axis drive platform, a first drive mechanism on the longitudinal axis drive platform for driving the drive cylinder to rotate, a support frame rotatably located on the side of the drive cylinder away from the cleaning frame, a second drive mechanism for driving the support frame to rotate, a roller shaft rotatably located on the support frame, a third drive mechanism for driving the roller shaft to rotate, a hinge seat fixed to the outside of the roller shaft, and a cleaning scraper rotatably located on the hinge seat.

[0009] Furthermore, the base includes a roller slider slidably connected in a groove at the top of the base and a placement plate fixedly connected to the top of the roller slider. The top of the placement plate is fixedly connected to symmetrically distributed mounting blocks for limiting the sensor device. The tops of the two mounting blocks are connected to pressing members for applying downward pressure to the sensor device. Limiting members for locking the position of the placement plate are fixedly connected to both sides of the placement plate.

[0010] Furthermore, the pressing component includes two insert rods inserted into the top of the two mounting blocks and a pressure plate fixedly connected to the top of the two insert rods.

[0011] Furthermore, the warning component includes two support rods fixedly connected to the top of the conveyor trolley and a warning sign fixedly connected to the top of the two support rods. A warning sign is fixedly connected to the front of the warning sign, and an audible and visual warning light that provides sound and light warnings is fixedly connected to the top of the warning sign.

[0012] Furthermore, the adjustable foot pad includes an inner screw cylinder fixedly connected to the bottom of the conveying trolley and a screw rod threadedly connected to the bottom of the inner screw cylinder, with the foot pad body fixedly connected to the end of the screw rod away from the inner screw cylinder.

[0013] A building tilt warning method for building inspection includes the following steps:

[0014] The first step is to control the mobile platform to move along the surface of the floor slab to be tested, so that the mobile platform and the floor slab surface are kept in parallel contact. During this process, the sensor device on the base collects the absolute tilt angle data relative to the vertical line of gravity in real time. If the angle data continues to deviate from the horizontal zero position, it is determined that the floor slab is tilted as a whole. If the angle data changes in a wavy manner during the movement, it is determined that the flatness of the floor slab is abnormal.

[0015] The second step involves moving the device to the wall to be tested, moving the bottom roller slider of the sensor device into the horizontal groove of the extension plate, and then driving the rotating shaft to rotate via the worm gear of the rotating shaft. The rotation of the worm gear drives the lead screw to rotate, which in turn causes the square slider to move longitudinally within the guide frame. The square slider then drives the extension plate to move longitudinally. During the upward movement of the extension plate, the drive gear at the rear end contacts the rack and rotates 90°. The end of the drive gear and the limiting tooth are in contact with the side wall of the guide frame, causing the extension plate to rise vertically. When it reaches the top, the drive gear will be positioned in the clearance groove on one side of the guide frame, allowing the extension plate to move. Simultaneously, the moving platform... The extension plate moves towards the wall so that the rotating wheel on one side of the extension plate is in contact with the wall, thereby controlling the two rotating wheels on the extension plate to contact the wall. The servo cylinder is activated, and then the servo cylinder drives the base to move longitudinally. The base drives the connecting plate and the extension plate to move longitudinally. During the movement, the sensor device sends the longitudinal and lateral coordinates to the processor. The processor detects the coordinate difference during the movement and drives the base to move the sensor device up and down in the vertical direction. During this process, the sensor device collects the absolute tilt angle of the wall at different heights in real time. If the angle data deviates from the 90° vertical reference, it is determined that the wall is tilted.

[0016] The third step is to control the warning component to issue an audible and visual alarm signal when the calculated tilt exceeds the safety threshold, and mark the location as an abnormal point in the recorded data.

[0017] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:

[0018] This building tilt warning device and its warning method for building inspection can flexibly adjust the height of the base through a servo electric cylinder. Combined with the lateral sliding of the base, it expands the detection range and can meet the building tilt detection needs of different heights and lateral positions. The mounting block, pressing component and limiting component of the base work together to ensure that the sensor equipment is stably installed, avoid displacement during the detection process and improve detection accuracy.

[0041] The rotary drive device 11 includes a connecting plate 1101 located on one side of the base 3, a rotating shaft 1102 rotatably mounted on the top surface of the connecting plate 1101, a first servo motor 1103 for driving the rotating shaft 1102 to rotate, a worm gear 1104 located at the end of the rotating shaft 1102, a guide frame 1105 located on the top surface of the connecting plate 1101, guide frames 1106 located on the front and rear sides of the guide frame 1105, a lead screw 1107 rotatably mounted inside the guide frame 1106, and a worm wheel 11 located at the bottom of the lead screw 1107 and meshing with the worm gear 1104. 08. A square slider 1109 is screwed onto the outside of the lead screw 1107 and slidably connected to the guide frame 1106. The extension plate 10 is rotatably disposed between the square sliders 1109. A drive gear 1110 is detachably connected to the rear end face of the extension plate 10. A rack 1111 is provided on one side of the guide frame 1106 for driving the drive gear 1110 to rotate 90°. Limiting teeth 1112 are horizontally spaced at the end of the drive gear 1110. A clearance groove 1113 is provided on the top of the guide frame 1106 to allow the drive gear 1110 to rotate.

[0042] When it is necessary to detect the wall tilt, the bottom roller slider 45 of the sensor device 5 is moved into the horizontal groove 12 of the extension plate 10. Then, the first servo motor 1103 drives the rotating shaft 1102 to rotate. The worm 1104 of the rotating shaft 1102 drives the lead screw 1107 to rotate through the worm wheel 1108. The rotation of the lead screw 1107 drives the square slider 1109 to move longitudinally within the guide frame 1105. The square slider 1109 drives the extension plate 10 to move longitudinally. During the upward movement of the extension plate 10, the drive gear 1110 at the rear end contacts the rack 1111 and rotates 90°.

When it reaches the top, the drive gear 1110 will be located in the clearance groove 1113 on one side of the guide frame 1106, and the extension plate 10 can move. At the same time, the moving platform 9 moves towards the wall, causing the rotating wheel 110 on one side of the extension plate 10 to move. 3. The base 3 is aligned with the wall surface, and then the servo cylinder 6 drives the base 3 to move longitudinally. The base 3 drives the connecting plate 1101 and the extension plate 10 to move longitudinally. During the movement, the sensor device 5 sends the longitudinal and lateral coordinates to the processor. The processor detects the coordinate difference during the movement.

[0043] The pressing component 41 includes two insert rods 412 inserted into the top of the two mounting blocks 42 and a pressure plate 411 fixedly connected to the top of the two insert rods 412. The two insert rods 412 of the pressing component 41 are respectively inserted into the top of the two mounting blocks 42, and downward pressure can be applied to the sensor device 5 from above to ensure uniform pressure. The pressure plate 411 connects the two insert rods 412, which makes it easy for the operator to insert and remove the entire component. Holding the pressure plate 411 makes it easier to operate the pressing component 41.

[0044] The warning component 7 includes two support rods 73 fixedly connected to the top of the conveyor trolley 1 and a warning sign 72 fixedly connected to the top of the two support rods 73. A warning sign 74 is fixedly connected to the front of the warning sign 72, and an audible and visual warning light 71 that provides sound and light warnings is fixedly connected to the top of the warning sign 72.

[0045] The support pole 73 provides stable support for the warning sign 72, ensuring that the warning sign 72 is at a suitable height and is more easily noticed by people in the surrounding area. The warning sign 74 at the front of the warning sign 72 visually reminds people of the risk of building tilt. The sound and light warning light 71 emits sound and light warnings at the same time, making the warning effect more significant.

[0046] The adjustable foot pad 8 includes an inner screw cylinder 81 fixedly connected to the bottom of the conveyor trolley 1 and a screw rod 82 threadedly connected to the bottom of the inner screw cylinder 81. The foot pad body 83 is fixedly connected to the end of the screw rod 82 away from the inner screw cylinder 81.

[0047] The inner screw 81 of the adjustable foot pad 8 is threadedly connected to the screw 82. By rotating the screw 82, the height of the foot pad body 83 can be adjusted, thereby adjusting the level of the conveyor trolley 1. When the device is placed on an uneven ground, the operator can adjust the height of the four adjustable foot pads 8 respectively to keep the conveyor trolley 1 level with the floor slab, ensuring that the sensor device 5 is in a horizontal detection state and improving the detection accuracy.

[0048] The mobile platform 9 is equipped with a cleaning device 14 located below the extension plate 10. The cleaning device 14 includes a cleaning frame 1401 mounted on the mobile platform 9, a longitudinal axis drive platform 1402 mounted on the cleaning frame 1401 for longitudinal movement, a drive cylinder 1403 mounted on the longitudinal axis drive platform 1402, a first drive mechanism 1404 mounted on the longitudinal axis drive platform 1402 for driving the drive cylinder 1403 to rotate, and a support frame 140 rotatably mounted on the side of the drive cylinder 1403 away from the cleaning frame 1401. 5. A second drive mechanism 1406 for driving the support frame 1405 to rotate, a roller 1407 rotatably mounted on the support frame 1405, a third drive mechanism 1408 for driving the roller 1407 to rotate, a hinge seat 1409 fixed to the outside of the roller 1407, and a cleaning scraper 1410 rotatably mounted on the hinge seat 1409. The cleaning scraper 1410 can rotate 180°, and the shape of the cleaning scraper 1410 in the front view is V-shaped. The thickness of the cleaning scraper 1410 gradually decreases from the middle to both sides.

[0049] The roller 1407 has an extension shaft 1419 on one side, and the extension shaft 1419 has a conical surface 1411 on the side away from the roller 1407. The roller 1407 has an external thread 1412 on the side near the conical surface 1411. The third drive mechanism 1408 includes a drive gear 1413 on one side of the support frame 1405, a second servo motor 1414 for driving the drive gear 1413 to rotate, a driven gear 1415 on the outside of the conical surface 1411 of the roller 1407, a conveyor belt 1416 between the drive gear 1413 and the driven gear 1415, an adjusting nut 1417 screwed on the outside of the roller 1407, and a spring 1418 between the adjusting nut 1417 and the support frame 1405. The longitudinal axis drive platform 1402, the drive cylinder 1403, the first drive mechanism 1404 and the second drive mechanism 1406 are all prior art and will not be described in detail here.

[0050] During inspection, in order to prevent obstacles (such as sand and gravel) in the path of the device, the second servo motor 1414 is started. The second servo motor 1414 drives the roller 1407 to rotate through the drive gear 1413, the conveyor belt 1416 and the driven gear 1415. The rotation of the roller 1407 drives the cleaning scraper 1410 to rotate and unfold outward to clean the obstacles in the path of the device.

[0051] The third drive mechanism 1408 has a protective function. When the cleaning scraper 1410 on the outer side of the roller 1407 comes into contact with the surface of the hard concrete layer or exposed aggregate on the device's travel path, the roller 1407 will generate resistance. Since the conical surface 1411 on the roller 1407 meshes with the internal hole of the driven gear 1415, when subjected to large resistance, the conical surface 1411 on one side of the roller 1407 will disengage from the internal hole of the driven gear 1415. The driven gear 1415 will remain idle and will not drive the roller 1407 to rotate, thus avoiding hard contact that could damage the cleaning device 14. When it is necessary to adjust the torque of the roller 1407, the adjusting nut 1417 is rotated. The distance between the adjusting nut 1417 and the support frame 1405 decreases, and the clamping force between the conical surface 1411 on one side of the roller 1407 and the driven gear 1415 increases, thereby adjusting the torque.

[0052] The cleaning device 14 cleans up obstacles in the path of the device, effectively avoiding inaccurate tilt detection due to obstacles.

[0053] Based on the same inventive concept, a building tilt warning method for building inspection is also proposed, comprising the following steps:

[0054] The first step is to control the moving platform 9 to move along the surface of the floor slab to be tested, so that the moving platform 9 and the floor slab surface are in parallel contact. During this process, the sensor device 5 on the base 3 collects the absolute tilt angle data relative to the vertical line of gravity. If the angle data continues to deviate from the horizontal zero position, it is determined that the floor slab is tilted as a whole. If the angle data changes in a wavy manner during the movement, it is determined that the flatness of the floor slab is abnormal.

[0055] The second step involves moving the device to the wall to be tested, moving the bottom roller slider 45 of the sensor device 5 into the transverse groove 12 of the extension plate 10, and then driving the rotating shaft 1102 to rotate via the first servo motor 1103. The worm gear 1104 of the rotating shaft 1102 drives the lead screw 1107 to rotate via the worm wheel 1108. The rotation of the lead screw 1107 causes the square slider 1109 to move longitudinally within the guide frame 1105. The square slider 1109 drives the extension plate 10 to move longitudinally. During the upward movement of the extension plate 10, the drive gear 1110 at the rear end contacts the rack 1111 and rotates 90°. The end of the drive gear 1110 and the limiting tooth 1112 are in contact with the side wall of the guide frame 1106, and the extension plate 10 will rise vertically. When it reaches the top, the drive gear 1110 will be located in the guide frame 1106. The clearance groove 1113 on one side of frame 1106 allows the extension plate 10 to move. At the same time, the moving platform 9 moves towards the wall so that the rotating wheel 13 on one side of the extension plate 10 is in contact with the wall, thereby controlling the two rotating wheels 13 on the extension plate 10 to contact the wall. The servo cylinder 6 is activated, and then the servo cylinder 6 drives the base 3 to move longitudinally. The base 3 drives the connecting plate 1101 and the extension plate 10 to move longitudinally. During the movement, the sensor device 5 sends the longitudinal and lateral coordinates to the processor. The processor detects the coordinate difference during the movement and drives the base 3 to move the sensor device 5 up and down in the vertical direction. During this process, the sensor device 5 collects the absolute tilt angle at different heights of the wall in real time. If the angle data deviates from the 90° vertical reference, it is determined that the wall is tilted.

[0056] Third, when the calculated tilt exceeds the safety threshold, the processor controls the warning component 7 to issue an audible and visual alarm signal and marks the location as an abnormal point in the recorded data.

A transverse groove for docking with the slide groove is provided on the two sides of the top surface of the extension plate. The mobile platform is equipped with a cleaning device located below the extension plate. The cleaning device includes a cleaning frame on the mobile platform, a longitudinal axis drive platform on the cleaning frame for longitudinal movement, a drive cylinder on the longitudinal axis drive platform, a first drive mechanism on the longitudinal axis drive platform for driving the drive cylinder to rotate, a support frame rotatably located on the side of the drive cylinder away from the cleaning frame, a second drive mechanism for driving the support frame to rotate, a roller shaft rotatably located on the support frame, a third drive mechanism for driving the roller shaft to rotate, a hinge seat fixed to the outside of the roller shaft, and a cleaning scraper rotatably located on the hinge seat. The mobile platform maintains parallel contact with the floor slab surface. The sensor equipment on the base collects the absolute tilt angle data relative to the vertical line of gravity in real time. If the angle data continuously deviates from the horizontal zero position, it is determined that the floor slab is tilted as a whole. If the angle data changes in a wavy manner during the movement, it is determined that the flatness of the floor slab is abnormal. Next, move the device to the wall to be tested, move the bottom roller slider of the sensor device into the horizontal groove of the extension plate, and then the first servo motor drives the rotating shaft to rotate. The worm gear of the rotating shaft drives the lead screw to rotate through the worm wheel. The rotation of the lead screw drives the square slider to move longitudinally in the guide frame. The square slider drives the extension plate to move longitudinally. During the upward movement of the extension plate, the drive gear at the rear end contacts the rack and rotates 90°. The drive gear moves the clearance groove on one side of the guide frame. At the same time, the moving platform moves towards the wall so that the rotating wheel on one side of the extension plate is in contact with the wall. Then, the servo electric cylinder drives the base to move longitudinally. The base drives the connecting plate and the extension plate to move longitudinally. During the movement of the sensor device, the longitudinal and lateral coordinates are sent to the processor. The processor detects the coordinate difference during the movement and drives the base to move the sensor device up and down in the vertical direction. During this process, the sensor device collects the absolute tilt angle of the wall at different heights in real time. If the angle data deviates from the 90° vertical reference, it is determined that the wall is tilted.
