Technical Field
[0001] The utility model relates to the technical field of road brick flatness inspection, in particular to a road brick flatness inspection device. Background Art
[0002] Pavement bricks are a type of paving material that is widely used in urban roads, sidewalks, squares, parks, parking lots and other places. Pavement bricks can be divided into many types, such as concrete permeable bricks, sintered pavement bricks, imitation stone PC bricks, ceramic granular bricks, etc. The surface itself is flat, but after laying, there are high requirements for its overall flatness.
[0003] Currently, the overall flatness of paved paving bricks is mainly tested by the naked eye and a wire drawing method, which has low accuracy, large errors, and low inspection efficiency. It is not possible to quickly inspect the flatness of paving bricks over a large area. Therefore, it is necessary to design a paving brick flatness inspection device to address the above problems. Utility Model Content
[0004] The purpose of the present utility model is to provide a device for inspecting the flatness of pavement bricks, so as to solve at least one technical problem raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pavement brick flatness inspection device, comprising a vehicle body, an adjusting sleeve rotatably mounted on one side of the vehicle body through a bearing seat, an inner wall of the adjusting sleeve connected to one end of a horizontal threaded rod, the other end of the horizontal threaded rod fixedly connected to one side of a movable plate, the movable plate passing through a stabilizing window, the stabilizing window being provided on the other side of the vehicle body, a stabilizing splint fixedly mounted on the outer wall of the other side of the vehicle body, the stabilizing splint being in contact with the surface of the movable plate, and an extrusion bolt threadedly mounted on the stabilizing splint;
[0006] A limit hole is vertically provided on the other side of the movable plate, a vertical threaded rod is installed through the limit hole, a locking nut is installed on the vertical threaded rod, a base plate is fixed to the bottom end of the vertical threaded rod, and a top ranging probe is installed at the bottom end of the base plate;
[0007] A bottom window is provided at the bottom end of the vehicle body, a rotating plate is movably installed on the bottom of the inner wall of the vehicle body through a side shaft, a vortex spring is fixedly installed between the side wall of the rotating plate and the inner wall of the vehicle body, an inspection wheel is installed at one end of the bottom surface of the rotating plate, and a bottom ranging probe is fixed at the other end of the bottom surface of the rotating plate.
[0008] Preferably, the adjusting sleeve is threadedly connected to the horizontal threaded rod, and the horizontal threaded rod is symmetrically distributed about the center of the movable plate.
[0009] Preferably, the movable plate is slidably connected to the stable window, and stable splints are fixedly installed symmetrically on the upper and lower edges of the outer opening of the stable window about the center of the movable plate.
[0010] Preferably, the vertical threaded rods are slidably connected to the limiting holes, and the vertical threaded rods are symmetrically distributed about the center of the base plate.
[0011] Preferably, the locking nuts are symmetrically distributed on the vertical threaded rod about the center of the limiting hole, and the length of the vertical threaded rod is greater than 1 / 3 of the overall height of the vehicle body.
[0012] Preferably, the top ranging probes are distributed at equal intervals on the bottom surface of the substrate, and the overall width of the substrate is greater than 2 / 3 of the width of the vehicle body when viewed from above.
[0013] Preferably, the bottom ranging probes are distributed at equal intervals on one end of the bottom surface of the rotating plate, and the distance from the bottom ranging probes to the horizontal straight line where the center of the side shaft is located is greater than the distance from the inspection wheel to the horizontal straight line where the center of the side shaft is located.
[0014] Preferably, a locking pulley is installed at the bottom end of the vehicle body, the bottom end of the locking pulley and the bottom end of the inspection wheel are on the same horizontal plane, and the diameter of the inspection wheel is larger than the diameter of the locking pulley.
[0015] The pavement brick flatness inspection device of the utility model has the following beneficial effects:
[0016] The new structural design uses multi-position adjustable distance measuring probes to monitor the distance to the pavement brick surface in real time while the device is moving. This not only has high monitoring efficiency but is also more accurate than traditional visual inspection and wire drawing inspection, while also saving manpower.
[0017] 1. By rotating the adjustment sleeve, the horizontal threaded rod is pulled in and out, allowing the movable plate to slide linearly along the stabilizing window and stabilizing splint. The vertical threaded rod, together with the base plate and the top ranging probe, slides vertically along the limit hole. This allows the distance between the top ranging probe and the vehicle body and the ground to be easily adjusted to accommodate different sizes of pavement bricks. This ensures that the distance between the top ranging probe and the vehicle body is appropriate, minimizing the impact of bumps caused by the vehicle moving on the pavement bricks on the top ranging probe.
[0018] 2. The inspection wheel installed at one end of the rotating plate is always pressed against the surface of the pavement bricks by the elastic force of the vortex spring. When the pavement bricks fluctuate, the inspection wheel remains in contact with the surface of the pavement bricks. The bottom distance measuring probe installed at the other end of the rotating plate will rotate significantly due to the off-center installation of the side shaft, causing the data measured by the bottom distance measuring probe to change significantly, assisting the top distance measuring probe to avoid omissions.

[0032] See also Figure 1-5 The utility model provides a technical solution: a pavement brick flatness inspection device, including a vehicle body 1, an adjusting sleeve 2, a horizontal threaded rod 3, a movable plate 4, a stabilizing window 5, a stabilizing splint 6, an extrusion bolt 7, a limiting hole 8, a vertical threaded rod 9, a locking nut 10, a base plate 11, a top distance measuring probe 12, a bottom window 13, a side shaft 14, a rotating plate 15, a vortex spring 16, an inspection wheel 17, a bottom distance measuring probe 18 and a locking pulley 19. The adjusting sleeve 2 is rotatably installed on one side of the vehicle body 1 through a bearing seat, the inner wall of the adjusting sleeve 2 is connected to one end of the horizontal threaded rod 3, and the other end of the horizontal threaded rod 3 is fixedly connected to one side of the movable plate 4, the movable plate 4 passes through the stabilizing window 5, and the stabilizing window 5 is opened on the other side of the vehicle body 1. A stabilizing splint 6 is fixedly installed on the outer wall of the other side of the vehicle body 1, and the stabilizing splint 6 is in contact with the surface of the movable plate 4. An extrusion bolt 7 is threadedly installed on the stabilizing splint 6.
[0033] A limit hole 8 is vertically opened on the other side of the movable plate 4, a vertical threaded rod 9 is installed through the limit hole 8, a locking nut 10 is installed on the vertical threaded rod 9, a base plate 11 is fixed to the bottom end of the vertical threaded rod 9, and a top ranging probe 12 is installed at the bottom end of the base plate 11;
[0034] A bottom window 13 is provided at the bottom end of the vehicle body 1, and a rotating plate 15 is movably installed at the bottom of the inner wall of the vehicle body 1 through a side shaft 14. A vortex spring 16 is fixedly installed between the side wall of the rotating plate 15 and the inner wall of the vehicle body 1, an inspection wheel 17 is installed at one end of the bottom surface of the rotating plate 15, and a bottom ranging probe 18 is fixed at the other end of the bottom surface of the rotating plate 15.
[0035] In this example, the adjusting sleeve 2 is threadedly connected to the horizontal threaded rod 3, and the horizontal threaded rod 3 is symmetrically distributed about the center of the movable plate 4. The above structural design enables the adjusting sleeve 2 to utilize the threaded connection relationship to drive the horizontal threaded rod 3 to move the movable plate 4 horizontally when rotating.
[0036] The movable panel 4 and the stable window 5 in this example are slidably connected, and the upper and lower edges of the outer opening of the stable window 5 are fixedly installed with stable splints symmetrically about the center of the movable panel 4. The above structural design ensures that the movable panel 4 can be horizontally displaced linearly along the stable window 5 and the stable splint 6.
[0037] In this example, the vertical threaded rod 9 is slidably connected to the limiting hole 8. The vertical threaded rod 9 is symmetrically distributed about the center of the base plate 11. The above structural design enables the vertical threaded rod 9 to adjust the vertical position of the base plate 11 along the limiting hole 8.
[0038] The locking nut 10 in this example is symmetrically distributed on the vertical threaded rod 9 about the center of the limiting hole 8. The length of the vertical threaded rod 9 is greater than 1 / 3 of the overall height of the vehicle body 1. The above structural design enables the relative position of the vertical threaded rod 9 and the limiting hole 8 to be easily fixed, and the vertical adjustment range of the vertical threaded rod 9 is large.
[0039] In this example, the top ranging probes 12 are evenly spaced on the bottom surface of the substrate 11. The overall width of the substrate 11 is greater than 2 / 3 of the width of the vehicle body 1 when viewed from above. The above structural design enables the top ranging probes 12 to detect a wider range of pavement bricks in front.
[0040] In this example, the bottom ranging probes 18 are evenly spaced at one end of the bottom surface of the rotating plate 15. The distance from the bottom ranging probe 18 to the horizontal straight line where the center of the side shaft 14 is located is greater than the distance from the inspection wheel 17 to the horizontal straight line where the center of the side shaft 14 is located. The above structural design enables the other end of the rotating plate 15 where the inspection wheel 17 is installed to rotate significantly when the end of the rotating plate 15 where the inspection wheel 17 is installed is rotated.
[0041] In this example, a locking pulley 19 is installed at the bottom end of the vehicle body 1. The bottom end of the locking pulley 19 and the bottom end of the inspection wheel 17 are on the same horizontal plane. The diameter of the inspection wheel 17 is larger than the diameter of the locking pulley 19. The above structural design ensures that the inspection wheel 17 can move stably on the flat surface of the pavement bricks, and can still move stably in accordance with the surface of the pavement bricks when encountering pavement bricks with large undulations.
[0042] Working principle: When using this device, push the vehicle body 1 to the paving brick area to be tested. Figure 2 The vortex spring 16 is in a compressed state, which always gives the rotating plate 15 a clockwise rotation force, so that the bottom end of the inspection wheel 17 is stably fitted with the surface of the pavement brick;
[0043] According to the size of the pavement bricks, the symmetrically distributed adjusting sleeves 2 are rotated in the same direction at the same time. The adjusting sleeves 2 are rotated to retract or push out the horizontal threaded rod 3. The horizontal threaded rod 3 drives the movable plate 4 to slide stably between the stabilizing window 5 and the stabilizing splint 6 until the distance between the top ranging probe 12 and the vehicle body 1 is appropriate. Stop rotating the adjusting sleeve 2, lock the horizontal threaded rod 3 by using the thread self-locking, and rotate the extrusion bolt 7 to squeeze the movable plate 4 to fix it. Then, rotate the symmetrically distributed locking nuts 10 away from the upper and lower end surfaces of the movable plate 4, push the vertical threaded rod 9 to carry the base plate 11 and the top ranging probe 12 to slide vertically along the limit hole 8, until the height of the top ranging probe 12 is appropriate, and reset the rotationally symmetrically distributed locking nuts 10 to squeeze the upper and lower end surfaces of the movable plate 4 to fix it.
[0044] The vehicle body 1 is pushed forward, and the top distance measuring probe 12 performs real-time distance detection on the pavement bricks in front of the vehicle body 1. The inspection wheel 17 is in contact with the surface of the pavement bricks below the vehicle body 1. When the pavement bricks become uneven, the rotating plate 15 rotates under the elastic force of the vortex spring 16 to ensure that the inspection wheel 17 is always in contact with the surface of the pavement bricks below the vehicle body 1. The bottom distance measuring probe 18 at the other end of the rotating plate 15 rotates significantly and abnormal measurement data is displayed. Combined with the measurement data of the top distance measuring probe 12, the unqualified flatness areas are accurately determined.
[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
