Description

Technical Field

[0001] The utility model relates to the technical field of ground detection, in particular to a ground flatness inspection device. Background Technique

[0002] The research on the laying technology of building wall and ground projects mainly focuses on the research of decoration construction technology of walls and floors, including material selection, construction methods, quality control and other issues. The reasons for detecting the flatness of building ground mainly include ensuring product quality, guiding the production process, ensuring service performance and meeting customer needs. The allowable deviation of the flatness of building ground is 5mm. This standard applies to the surface flatness of the ground.

[0003] After retrieval, the patent document with the publication number: CN214065955U discloses a device for measuring the flatness of a building ground. By pushing the cylindrical push rod forward with force, the measuring device moves forward, and then observes the lifting state of the measuring columns arranged at the top of the bearing plate. When the height remains unchanged, it means that the requirement is met; when the height rises, it indicates that the ground below bulges upward; when the height drops, it indicates that the ground below sinks downward. The measuring device visually displays the flatness of the ground by the lifting state of the measuring columns at the top of the bearing plate, which is convenient for users to repair according to different situations after detection.

[0004] When the above device is actually used, the user needs to push the measuring device forward and also needs to look down to observe the lifting states of multiple measuring columns. When the single undulation of the measuring columns is not large, it is very difficult to observe the lifting state with the naked eye. Content of the Utility Model

Specific implementation mode

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

[0023] As Figures 1-4 shown, it relates to a ground flatness inspection device, including a seat 1. A plurality of round sleeves 2 are uniformly and fixedly communicated at the top of the seat 1. The inner walls of the plurality of round sleeves 2 are all slidably connected with measuring rods 3. A plurality of sliding holes are uniformly opened at the bottom of the seat 1. The inner walls of the plurality of sliding holes are respectively slidably connected with the outer walls of the plurality of measuring rods 3. After the plurality of measuring rods 3 encounter an uneven ground, they move up and down through the plurality of sliding holes and the plurality of round sleeves 2. Balls 4 are rotatably connected to the bottoms of the plurality of measuring rods 3, and circular contact blocks 5 are fixedly connected to the tops of the plurality of measuring rods 3. After the plurality of measuring rods 3 move up and down, the circular contact blocks 5 are driven to move.

[0024] Two return frames 6 are fixedly connected to the top of the seat 1. Two threaded holes are opened on the outer walls of the two return frames 6. The inner walls of the four threaded holes are all threadedly connected with screws 7. One ends of the four screws 7 are rotatably connected with rectangular long plates 8. The four screws 7 drive the four rectangular long plates 8 to move. Two vertical grooves are opened on the outer walls of the two return frames 6. The inner walls of the four vertical grooves are respectively slidably connected with the two ends of the two rectangular long plates 8.

[0025] A flashing buzzer alarm 13 is fixedly connected to the top of the seat 1. A U-shaped handle 14 is fixedly connected to the top of the seat 1. Four universal wheels 15 are fixedly connected to the bottom of the seat 1.

[0026] The outer wall of the rectangular long plate 8 is provided with a pressure mechanism. The pressure mechanism includes a plurality of springs 10. A plurality of pressure sensors 9 are evenly and fixedly embedded on the outer wall of the rectangular long plate 8. When pressure is applied to the sensitive element at the detection end of the pressure sensor 9, it will deform, and this deformation is proportional to the magnitude of the pressure. The electronic components in the sensitive element will convert this deformation and generate corresponding electrical signals.

[0027] One ends of a plurality of springs 10 are respectively fixedly connected to the outer walls of the detection ends of the plurality of pressure sensors 9. The other ends of the plurality of springs 10 are respectively fixedly connected to two contact plates 11. Existing spirit levels are installed on the outer walls of the two contact plates 11 for horizontal calibration to avoid errors. A plurality of through holes 12 are evenly formed in the outer wall of one of the contact plates 11. The initial pressure exerted by the two contact plates 11 and the plurality of springs 10 on the plurality of pressure sensors 9 is zeroed. The plurality of pressure sensors 9 are connected to a flashing buzzer alarm 13 by using existing circuits, and the circuits, electronic components and modules involved are all prior arts and do not involve improvements to software and methods.

[0028] Working principle: When in use, the whole is moved to the building ground to be detected. Push the U-shaped handle 14 to drive the seat 1 to move through the four universal wheels 15. During this process, the balls 4 at the bottoms of the plurality of measuring rods 3 are in contact with the ground. When the plurality of balls 4 encounter uneven ground and move up and down, they drive the plurality of measuring rods 3 to move up and down. The up and down movement of the plurality of measuring rods 3 drives the plurality of circular contact blocks 5 to move up and down. During the up and down movement of the circular contact blocks 5, if the degree of up and down undulation is greater than the distance between the two contact plates 11, it indicates that the plurality of measuring rods 3 encounter uneven ground and the up and down error is greater than the distance between the two contact plates 11, and there are potholes or protrusions on the ground. And after the up and down movement distance of the measuring rod 3 is greater than the distance between the two contact plates 11, at this time, the circular contact block 5 squeezes up or down onto the two contact plates 11, causing the two contact plates 11 to be stressed. At this time, the plurality of springs 10 on the two contact plates 11 are subjected to pressure and undergo compressive deformation, and the generated compressive elastic force acts on the plurality of pressure sensors 9 relatively. After the pressure sensors 9 collect the pressure signals and convert them into electrical signals for output, the flashing buzzer alarm 13 gives a reminder. And the four screw rods 7 can be rotated in sequence to make the four rectangular long plates 8 move relatively in pairs of two, change the distance between the two contact plates 11, and adjust the allowable up and down error of the flatness according to actual needs.
