Description

Technical Field

[0001] This invention relates to the field of building inspection technology, and specifically to a building foundation inspection device for verticality detection structures. Background Technology

[0002] In the construction of cast-in-place concrete building walls, after each floor of concrete wall is poured and solidified, the verticality of the wall of the poured floor must be tested. Only after the test is qualified can the next floor of wall be poured; otherwise, a major accident may occur.

[0003] Existing wall verticality testing devices typically involve suspending a plumb bob at one end of a testing rope, placing it close to the wall to be tested, and then visually inspecting the wall's verticality. This requires the user's line of sight to be parallel to one side of the wall being measured. Due to the varying wall structures, this method introduces limitations to the verticality testing. To address these technical issues, patent publication number CN216049777U describes a method where the base is adjusted using support feet and threaded rods. However, visual inspection alone cannot accurately level the wall, and adjustments require adjusting multiple sets of support feet, resulting in a large workload, low efficiency, and reduced device convenience. Summary of the Invention

A through groove is opened on the first rotating rod, and a second rotating rod is rotatably installed in the through groove. The first rotating rod and the second rotating rod are perpendicular. A cone block and an installation groove are fixedly installed at both ends of the second rotating rod, respectively. The weight of the cone block is much greater than the weight of the installation groove. A second pressure plate for fixing the first rotating rod is provided on the side plate, and a first pressure plate for fixing the second rotating rod is provided inside the first rotating rod.

[0007] A horizontal plate is slidably installed in the mounting slot. Multiple sets of vertical plates are arranged on the horizontal plate in sequence, and a top plate is provided on the top of the top vertical plate.

[0009] As a further aspect of the present invention: the first rotating rod has two sets of mounting holes communicating with the through groove. Both ends of the first rotating rod are threaded with cover plates. A first electric telescopic rod located in the mounting hole is fixedly installed on the cover plate. A first pressure plate is fixedly installed at the output end of the first electric telescopic rod. The first pressure plate cooperates with a fixing ring fixedly installed on the second rotating rod. The rotation axis of the fixing ring coincides with the rotation axis of the second rotating rod.

[0010] As a further embodiment of the present invention: a limiting groove is fixedly installed on the horizontal plate, the vertical plate is slidably installed in the limiting groove, a connecting plate is fixedly installed at one end of the vertical plate and a connecting groove is opened at the other end to cooperate with the connecting plate, multiple sets of vertical plates are connected sequentially through the connecting plate and the connecting groove, and the top plate is slidably installed on the connecting plate.

[0011] As a further embodiment of the present invention: a take-up shaft driven by a motor is rotatably mounted on the side plate, the lifting cable is wound on the take-up shaft and the end of the lifting cable is fixedly connected to the lifting plate, and a guide wheel for changing the moving direction of the lifting cable is rotatably mounted on the top plate.

[0012] As a further embodiment of the present invention: a limiting frame is fixedly installed on the lifting plate, and the laser ranging sensor is slidably installed in the limiting frame, and the limiting frame is threaded with fixing screws for fixing the laser ranging sensor.

[0013] As a further embodiment of the present invention: two sets of brackets are fixedly installed on the surface of the horizontal plate near the base, a base plate is slidably installed on the brackets, a screw that drives the base plate to move is rotatably installed on the horizontal plate, and the base plate is connected to a fixed pull wire.

[0015] The beneficial effects of this invention are:

[0016] (1) In this invention, the first rotating rod and the second rotating rod work synchronously and collaboratively under the action of the weight of the cone block, which realizes the rapid leveling of the installation groove and ensures that the installation groove is in a horizontal state, ensuring the correct reference during subsequent equipment installation and testing, and improving the testing speed and accuracy of the test results.

[0017] (2) In this invention, the equipment can be quickly installed by rapidly assembling the base, horizontal plate, vertical plate and top plate. At the same time, the detection height of the equipment can be adjusted according to the wall height measurement needs. After the detection is completed, the equipment can be quickly disassembled, reducing the space occupied by the equipment, making it convenient to carry and transport the equipment, and improving the practicality of the equipment.

[0018] (3) In this invention, the fixed pull wires are initially straightened and corrected by the lifting frame, and then the two sets of lifting frames are moved downward synchronously by the base plate, which ensures that the tension of the two sets of fixed pull wires on the top plate is the same, thereby avoiding the vertical plate from tilting to one side, ensuring that the track formed by the vertical plate is vertically distributed, and further improving the stability of the equipment and the accuracy of the detection.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-10 As shown, the present invention is a building foundation testing device for verticality detection structure, including a base 1, on which a power supply 17 and a data collection device body 18 are fixedly installed. A side plate 2 is fixedly installed on the base 1, and a first rotating rod 3 is rotatably installed on the side plate 2. A through groove 8 is opened on the first rotating rod 3, and a second rotating rod 4 is rotatably installed in the through groove 8. The first rotating rod 3 and the second rotating rod 4 are perpendicular. A cone block 5 and an installation groove 6 are fixedly installed at both ends of the second rotating rod 4, respectively. The weight of the cone block 5 is much greater than the weight of the installation groove 6. A second pressure plate 16 for fixing the first rotating rod 3 is provided on the side plate 2, and a first pressure plate 11 for fixing the second rotating rod 4 is provided inside the first rotating rod 3.

[0033] A horizontal plate 19 is slidably installed in the mounting slot 6. Multiple sets of vertical plates 21 are arranged on the horizontal plate 19 in sequence, and a top plate 24 is provided on the top of the top vertical plate 21. Multiple sets of fixing wires 25 are fixedly installed on the top plate 24. The end of the fixing wire 25 away from the top plate 24 is connected to the horizontal plate 19. A lifting plate 27 is slidably installed on the vertical plate 21. A laser rangefinder sensor 29 is arranged on the lifting plate 27. A limit frame 28 is fixedly installed on the lifting plate 27. The laser rangefinder sensor 29 is slidably installed in the limit frame 28, and a fixing screw for fixing the laser rangefinder sensor 29 is threaded on the limit frame 28. A lifting wire 30 is provided on the top plate 24 to drive the lifting plate 27 to move. A winding shaft 31 driven by a motor is rotatably installed on the side plate 2. The lifting wire 30 is wound around the winding shaft 31, and the end of the lifting wire 30 is fixedly connected to the lifting plate 27. A guide wheel 26 for changing the moving direction of the lifting wire 30 is rotatably installed on the top plate 24.

[0034] In practical application, the base 1 is placed on the side of the wall to be tested and fixed. Under the action of the gravity of the cone block 5, the first rotating rod 3 and the second rotating rod 4 will rotate. Since the weight of the cone block 5 is much greater than the weight of the mounting groove 6, the second rotating rod 4 will be in a vertical state after it stops. At this time, the second rotating rod 4 is fixed by the first pressure plate 11 and the first rotating rod 3 is fixed by the second pressure plate 16. After the fixing is completed, the horizontal plate 19 is installed in the mounting groove 6 and fixed by the fixing screws. Under the action of the gravity of the cone block 5, the first rotating rod 3 and the second rotating rod 4 work synchronously and collaboratively, realizing the rapid leveling of the mounting groove 6 and ensuring that the mounting groove 6 is in a horizontal state. This ensures the correct reference during subsequent equipment installation and testing, and improves the testing speed and the accuracy of the test results.

[0035] Next, the top plate 24 is installed on the top of a set of vertical plates 21, and the lifting cable 30 is released so that it passes through the guide wheel 26. Then, the vertical plates 21 are assembled in sequence, with the set of vertical plates 21 connected to the top plate 24 located at the top. The set number of vertical plates 21 are assembled according to the height of the wall. After assembly, the lifting plate 27 is installed on the bottom set of vertical plates 21. Then, the bottom set of vertical plates 21 is installed on the horizontal plate 19. Then, the lower end of the fixing cable 25 is connected to the horizontal plate 19 to apply downward pulling force to the top plate 24, so that multiple sets of vertical plates 21 form a stable whole. Then, the laser range sensor 29 is installed on the lifting plate 27 to complete the installation. Through the rapid assembly of the base 1, horizontal plate 19, vertical plate 21 and top plate 24, the equipment can be installed quickly. At the same time, the detection height of the equipment can be adjusted according to the wall height measurement needs. After the detection is completed, the equipment can be quickly disassembled, reducing the space occupied by the equipment, facilitating the carrying and transportation of the equipment, and improving the practicality of the equipment.

[0036] The motor drives the winding shaft 31 to rotate and wind up the lifting cable 30. The guide wheel 26 changes the direction of movement of the lifting cable 30. The lifting cable 30 pulls the lifting plate 27 to rise at a constant speed along the track formed by the vertical plate 21. At the same time, the laser range sensor 29 detects the distance from its installation position to the wall. The detection results are transmitted to the main body 18 of the data collection device. The inspection personnel can view the detection data through the main body 18 of the data collection device. The change in the distance between the laser range sensor 29 and the wall reflects the verticality of the wall. At the same time, the wall is fully measured, which makes it easy to compare the data to find the tilt position.

[0037] Please see Figure 3 , Figure 7 As shown, the present invention is a building foundation testing device for a verticality testing structure. A fixing plate 13 is fixedly installed at one end of the first rotating rod 3 near the side plate 2. A second electric telescopic rod 15 is fixedly installed on the side plate 2. The second electric telescopic rod 15 points towards the fixing plate 13 and a second pressure plate 16 is fixedly installed at the output end of the second electric telescopic rod 15. An L-shaped fixing frame 14 is fixedly installed on the side plate 2. One side of the fixing frame 14 slides in contact with the side of the fixing plate 13 away from the side plate 2.

[0038] Specifically, the first rotating rod 3 has two sets of mounting holes 12 that communicate with the through groove 8. Both ends of the first rotating rod 3 are threaded with cover plates 9. The cover plates 9 are fixedly installed with the first electric telescopic rod 10 located in the mounting holes 12. The first pressure plate 11 is fixedly installed at the output end of the first electric telescopic rod 10. The first pressure plate 11 is used in conjunction with the fixing ring 7 fixedly installed on the second rotating rod 4. The rotation axis of the fixing ring 7 coincides with the rotation axis of the second rotating rod 4.

[0039] In practical application, after the second rotating rod 4 is stationary in a vertical state, the first electric telescopic rod 10 drives the first pressure plate 11 to move until both sets of first pressure plates 11 simultaneously contact the fixing ring 7, thereby fixing the second rotating rod 4. At the same time, the second electric telescopic rod 15 drives the second pressure plate 16 to move closer to the fixing plate 13. The second pressure plate 16 presses the fixing plate 13 tightly onto the fixing frame 14, thereby fixing the first rotating rod 3 and ensuring that the second rotating rod 4 is in a vertical state.

[0040] Please see Figure 5 As shown, the present invention is a building foundation testing device for a verticality testing structure. A limiting groove 20 is fixedly installed on the horizontal plate 19, and the vertical plate 21 is slidably installed in the limiting groove 20. A connecting plate 22 is fixedly installed on one end of the vertical plate 21, and a connecting groove 23 that cooperates with the connecting plate 22 is opened on the other end. Multiple sets of vertical plates 21 are connected to the connecting groove 23 in sequence through the connecting plate 22, and the top plate 24 is slidably installed on the connecting plate 22.

[0041] In practical application, multiple sets of vertical plates 21 are connected to the connecting groove 23 in sequence through the connecting plate 22, and the bottom set of vertical plates 21 is placed in the limiting groove 20, thus completing the fixation of the vertical plates 21.

[0042] Please see Figure 6 , Figure 8 As shown, the present invention is a building foundation testing device for a verticality testing structure. Two sets of brackets 32 are fixedly installed on the surface of the horizontal plate 19 near the base 1. A base plate 33 is slidably installed on the brackets 32. A screw 34 that drives the base plate 33 to move is rotatably installed on the horizontal plate 19. The base plate 33 is connected to a fixed pull wire 25.

[0043] Specifically, a lifting frame 35 is slidably mounted on the substrate 33. The lifting frame 35 is L-shaped and a U-shaped connecting frame 36 is fixedly mounted at the end of the lifting frame 35. A third pressure plate 37 is installed inside the connecting frame 36 by fixing screws, and a fixing pull wire 25 is connected to the connecting frame 36.

[0044] In practical application, the lifting frame 35 is moved upward to its highest position. The fixing cable 25 passes naturally through the connecting frame 36. The fixing screws are rotated to press the fixing cable 25 onto the connecting frame 36 using the third pressure plate 37. Then, the lifting frame 35 is released, and the fixing cable 25 is straightened under its own weight. At this point, both sets of fixing cables 25 are straightened under the weight of the lifting frame 35, and the downward pull exerted by both sets of fixing cables 25 on the top plate 24 is the same. The lifting frame 35 is then fixed to the base plate 33 using fixing screws, and then secured by screws 34. The base plate 33 is moved downwards, which causes the lifting frame 35 to apply further tension to the fixed pull wire 25, further increasing the downward pull on the top plate 24 and ensuring the stability of the connection of multiple sets of vertical plates 21. The lifting frame 35 is used to initially straighten and correct the fixed pull wire 25. Then, the base plate 33 causes the two sets of lifting frames 35 to move downwards synchronously, ensuring that the tension of the two sets of fixed pull wires 25 on the top plate 24 is the same, thereby preventing the vertical plates 21 from tilting to one side and ensuring that the track formed by the vertical plates 21 is vertically distributed, further improving the stability of the equipment and the accuracy of the detection.
