[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Referring to Figures 1-4 , an embodiment provided by the present invention: a large-area floor flatness detection device, which includes at least two support columns 1. A counterweight base 2 is fixedly arranged at the bottom of each support column 1. A connection seat 3 is fixedly arranged at the top of the support column 1. Connection grooves 4 penetrate through both sides of the connection seat 3. A rack 5 is penetrated between the connection grooves 4 of adjacent connection seats 3. A mobile detection mechanism is arranged outside the rack 5;

[0024] The mobile detection mechanism includes a gear 6 and a micro motor 7. A micro motor 7 is fixedly arranged at one end of the gear 6. The output end of the micro motor 7 is fixedly connected to the gear 6. A connecting rod 8 is fixedly arranged at the other end of the gear 6. A connecting block 9 is sleeved outside the connecting rod 8. Connecting plates 10 are fixedly arranged at the bottoms of both the connecting block 9 and the micro motor 7. A fixed block 11 is fixedly arranged at one end of the connecting plate 10. A slide block 12 is fixedly arranged at the other end of the connecting plate 10. A support plate 13 is fixedly arranged between the bottoms of the two fixed blocks 11. An adjustable-length telescopic rod 15 is arranged at the bottom of the support plate 13. A flatness detection component 16 is fixedly arranged at the bottom of the telescopic rod 15. The telescopic rod 15 can be adjusted according to the detection height, and the length is fixed by a locking structure after adjustment.

[0025] In a preferred embodiment, a shock absorber 14 is arranged between the support plate 13 and the telescopic rod 15.

[0026] In this embodiment: By setting the micro motor 7, it drives the gear 6 to mesh and move on the rack 5. During the movement of the gear 6, the slider 12 at one end of the connecting plate 10 is synchronously slid in the strip-shaped groove 17, so as to increase the stability of the gear 6 during movement. At the same time, the connecting plate 10 drives the support plate 13 to move under the rack 5 through the fixed block 11. The vibration generated during the movement of the gear 6 will be dampened by the shock absorber 14, preventing the vibration from being transmitted to the flatness detection component 16 at the bottom through the telescopic rod 15. At this time, the flatness detection component 16 moves horizontally under the rack 5. The flatness detection component 16 is specifically a laser displacement sensor, which scans the surface of the floor by generating a laser beam, and determines parameters such as the height and flatness of the road surface by measuring the reflection time and intensity of the laser beam. The whole process is automated, reducing the influence of human factors on the detection results, further improving the stability and accuracy of the detection results, achieving large-area detection while reducing manpower and material resources.

[0027] Strip-shaped grooves 17 are penetrated through both sides of the rack 5, the slider 12 is movably connected with the strip-shaped groove 17, a magnetic attraction plate 18 is fixedly arranged at the connecting end of the rack 5, and a connecting hinge 19 is fixedly arranged at the rear side of the rack 5. The racks 5 are all connected through the connecting hinge 19.

[0028] In this embodiment: By setting the connecting hinge 19, multiple racks 5 can be folded and laid flat, and the magnetic attraction plate 18 is used to strengthen the stability of the connection of the rack 5, so as to reduce the occupied area, achieve convenient installation and disassembly, and be convenient to carry.

[0029] The number of the magnetic attraction plates 18 is two, and the magnetic attraction plates 18 attract each other magnetically. The rack 5 is movably connected with the connecting groove 4.

[0030] In this embodiment: By setting the magnetic attraction plate 18, the connection between the racks 5 is further strengthened.

[0031] The number of the racks 5 is three, and the lengths of the racks 5 are the same. Meshing tooth patterns are arranged on the surfaces of the gear 6 and the rack 5.

[0032] In this embodiment: Through the meshing tooth patterns on the surfaces of the gear 6 and the rack 5, the transmission between the gear 6 and the rack 5 is realized.

[0033] There is a certain distance between the support plate 13 and the bottom of the rack 5, and the connecting rod 8 is rotatably connected with the connecting block 9 idly.

[0034] In this embodiment: By setting the connecting rod 8 to be rotatably connected with the connecting block 9 idly, the connecting rod 8 is prevented from rotating synchronously with the connecting block 9.

[0035] A non-slip mat 20 is fixedly arranged at the bottom of the counterweight base 2, and the non-slip mat 20 is made of rubber. The numbers of the support columns 1, the connecting seats 3, the connecting grooves 4, the counterweight base 2 and the non-slip mat 20 are all two.

[0036] In this embodiment: By arranging two groups of support columns 1, connecting seats 3, connecting grooves 4, counterweight bases 2 and non-slip mats 20, the rack 5 can be supported at the relative distance of the support columns 1, and at the same time, the detection distance can be adjusted, and the stability during support is increased by using the counterweight base 2 and the non-slip mat 20.

[0037] Working principle: Before detection, the two support columns 1 are respectively placed on the floor to be detected through the counterweight base 2. According to the length of the ground to be detected, the relative positions of the two support columns 1 are moved so that they can be adjusted according to the size of the floor area. After confirmation, the multiple racks 5 are laid flat through the connecting hinge 19, and the connection between the racks 5 is further strengthened by using the magnetic attraction plates 18. At the same time, the gear 6 is placed above the rack 5, and the connecting plates 10 on both sides are inserted through the strip-shaped grooves 17, so that the sliders 12 are slidably connected with the strip-shaped grooves 17. Finally, one end of the rack 5 respectively penetrates through the connecting groove 4, and the rack 5 is supported by the connecting seat 3 to start the detection work. During disassembly, the multiple racks 5 can be folded through the connecting hinge 19, and the multiple magnetic attraction plates 18 are separated to reduce the occupied area, facilitate installation and disassembly, and are convenient to carry; during detection, the micro motor 7 is externally connected to a power supply to ensure the normal use of the micro motor 7, and then the micro motor 7 is started to drive the gear 6 to engage and move horizontally on the rack 5. During the movement of the gear 6, the slider 12 at one end of the connecting plate 10 slides synchronously in the strip-shaped groove 17, so as to increase the stability of the gear 6 during movement. At the same time, the connecting plate 10 drives the support plate 13 to move under the rack 5 through the fixing block 11. The vibration generated during the movement will be dampened by the shock absorber 14 to ensure that the shock absorber 14 can reduce the transmission of vibration and prevent the vibration from being transmitted to the flatness detection component 16 at the bottom through the telescopic rod 15. At this time, the flatness detection component 16 moves horizontally under the rack 5 and linearly detects the surface of the floor above the floor at the same time. The flatness detection component 16 is specifically a laser displacement sensor. The laser displacement sensor generates a laser beam to scan the surface of the floor, and determines parameters such as the height and flatness of the road surface by measuring the reflection time and intensity of the laser beam, reducing the influence of human factors on the detection results, further improving the stability and accuracy of the detection results, and achieving large-area detection while reducing manpower and material resources.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
