Description

Technical Field

[0001] The utility model belongs to the technical field of ground measurement, and in particular relates to a concrete ground leveling detection device. Background Art

[0002] The national regulations stipulate that the inspection standard for concrete flatness is based on the "Concrete Structure Construction Quality Acceptance Code" GB50204-2015. The dimensional deviation and inspection method requirements of cast-in-place structures require that the flatness deviation of the surface of cast-in-place concrete components after molding should be 8mm. The flatness of the concrete floor is related to all aspects of the construction process. Excessive error in the flatness of the floor will affect the development of later construction, resulting in unnecessary loss of manpower and material resources. Therefore, after the construction of the concrete floor is completed, it is necessary to test the flatness of the floor, that is, to check whether there are bulges or depressions on the floor. The traditional method of testing the flatness of the floor is that workers use a handheld level to test the flatness of multiple points on the floor. The testing process is time-consuming and labor-intensive, which affects the efficiency of the testing of the flatness of the floor and needs to be improved.

[0003] After searching, the utility model with patent publication number CN219736247U discloses a ground leveling device, which is roughly described as including a mounting ring, a movable component installed on the inner wall of the mounting ring, a controller fixedly connected to the top wall of the movable component, an operating handle fixedly connected to the top wall of the movable component, and several leveling components evenly installed on the top wall of the mounting ring.

[0004] Although the above-mentioned ground leveling device increases the detection range and improves the detection efficiency, the device requires manual operation of the operating handle to control the movement of the device, which requires workers to bend over for a long time to move, greatly wasting manpower.

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0022] like Figures 1 to 4 As shown: A concrete floor leveling detection device includes a support beam, a sliding seat, and a horizontal frame. The support beam can be extended and retracted along the length direction. Support legs 25 are provided at the bottom of the beam ends on both sides of the support beam. The sliding seat is assembled on the support beam. The sliding seat can move along the length direction of the support beam under the action of its own driving mechanism. The horizontal frame is connected to the sliding seat and suspended under the support beam. Several detection units are linearly arranged on the horizontal frame. The detection unit includes a mounting frame 9. A slide plate 10 is slidably connected between the vertical guide rails in the mounting frame 9. A guide column 11 is movably inserted at the bottom of the mounting frame 9. A distance sensor 13 is installed above the slide plate 10 in the mounting frame 9, and a warning light 23 is installed on the outside of the mounting frame 9.

[0023] When the sliding seat drives the horizontal frame to move along the support beam, the guide posts 11 of a row of detection units slide across the ground. The warning light 23 is used to light up when the distance sensor 13 detects abnormal data, so that workers can observe the abnormal position in time. In this way, the purpose of improving work efficiency is achieved. The distance sensor 13 is used to detect the distance between it and the skateboard 10. By default, the distance sensor 13 has a preset maximum and minimum value. When there is a bulge on the concrete floor, the guide post 11 drives the skateboard 10 to rise. When the distance sensor 13 detects that the distance between it and the skateboard 10 is less than the preset minimum value, the warning light 23 issues an alarm. When there is a depression on the concrete floor, the guide post 11 drives the skateboard 10 to descend. When the distance sensor 13 detects that the distance between it and the skateboard 10 is greater than the preset maximum value, the warning light 23 issues an alarm, thereby achieving the purpose of detecting the flatness of the ground.

[0024] The bottom end of the guide post 11 is inlaid with a ball 12, which is used to reduce the friction between the guide post 11 and the ground, thereby achieving the purpose of improving the stability of the equipment.

[0025] The support beam includes an outer sleeve 1 and an inner sleeve 2 that are movably connected. A sliding groove 4 is opened on the side surfaces of the outer sleeve 1 and the inner sleeve 2, and the sliding grooves 4 on the outer sleeve 1 and the inner sleeve 2 are aligned. A through groove 5 is opened on the bottom surfaces of the outer sleeve 1 and the inner sleeve 2, and the through grooves 5 on the outer sleeve 1 and the inner sleeve 2 are aligned.

[0026] The sliding seat comprises a positioning movable plate 3, a suspension rod 6, and two wheel assemblies. The positioning movable plate 3 slides in a chute 4. The suspension rod 6 and the two wheel assemblies are connected to the bottom of the positioning movable plate 3, with the suspension rod 6 centered and slidingly inserted in a through slot 5. The bottom of the suspension rod 6 is connected to the horizontal frame, and the two wheel assemblies are in rolling contact with the bottom surfaces of the outer sleeve 1 and the inner sleeve 2. The positioning movable plate 3 is inserted in the chute 4 to maintain the height of the sliding seat, thereby ensuring the accuracy of detection. The wheel assemblies roll on the outer sleeve 1 and the inner sleeve 2 to propel the sliding seat.

[0027] The wheel assembly includes a telescopic rod 18, a spring 22, a support plate 19, a bidirectional motor 20, and a roller 21. One end of the telescopic rod 18 is connected to the positioning movable plate 3, and the other end is connected to the support plate 19. The spring 22 is sleeved on the telescopic rod 18 and supported between the positioning movable plate 3 and the support plate 19. The bidirectional motor 20 is fixed to the bottom of the support plate 19, spanning the through slot 5. A roller 21 is mounted on each end of the bidirectional motor 20. Due to the height difference between the bottom surfaces of the outer sleeve 1 and the inner sleeve 2, the arrangement of the telescopic rod 18 and the spring 22 ensures that the spring 22 constantly pushes the telescopic rod 18 to extend. When the wheel assembly moves from the outer sleeve 1 to the inner sleeve 2, the telescopic rod 18 and spring 22 are compressed. When the wheel assembly moves from the inner sleeve 2 to the outer sleeve 1, the telescopic rod 18 and spring 22 extend.

[0028] The outer sleeve 1 is provided with a first vertical plate 14, and the inner sleeve 2 is provided with a second vertical plate 15. An axially fixed, circumferentially free threaded sleeve 16 is connected to the first vertical plate 14, and an axially fixed, circumferentially free screw 17 is connected to the second vertical plate 15. The screw 17 is screwed together with the threaded sleeve 16, and the ends of the screw 17 and the threaded sleeve 16 are connected to a turntable 24. The screw 17 and the threaded sleeve 16 can not only help support the outer sleeve 1 and the inner sleeve 2, but also adjust the joint length of the outer sleeve 1 and the inner sleeve 2, thereby adjusting the overall length of the support beam. Rotating the screw 17 and the threaded sleeve 16 drives the first vertical plate 14 and the second vertical plate 15 away from each other, thereby driving the outer sleeve 1 and the inner sleeve 2 to expand, making the equipment adaptable to indoor environments of different lengths.

[0029] The horizontal frame includes a support plate 8 and a support frame 7 . The top of the support frame 7 is connected to the suspension rod 6 , and the mounting frame 9 is fixed on the support plate 8 .

[0030] Two balancing rods 26 are connected to the top of the support frame 7. The two balancing rods 26 are symmetrical with the suspension rod 6 as the center. The balancing rods 26 extend into the through slot 5 and slide in contact with the through slot 5. The two balancing rods 26 assist in supporting the support frame 7 to prevent the support frame 7 from swinging.

[0031] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
