Description

Technical Field

[0001] The utility model relates to the technical field of floor slab thickness detection equipment, in particular to a building floor slab thickness detector. Background Art

[0002] A building floor thickness tester is a device used to measure the thickness of building floors. It usually uses sound wave technology to non-destructively detect the thickness of the floor. This device transmits sound waves to the surface of the floor, and then measures the time interval from the emission to the reception of the sound wave. According to the speed of sound waves propagating in the material, the thickness of the floor is calculated.

[0003] After searching, the Chinese patent authorization number CN214951103U discloses a thickness detector for building floors, including a base, an installation box and a transmitting probe. Moving wheels are installed at the four corners of the bottom of the base. A first groove is opened at the bottom of the base, and a supporting plate is provided below the first groove. A second electric telescopic rod is installed between the top of the supporting plate and the top of the first groove. A control button is provided on one side of the base. Two symmetrically arranged slide grooves are provided on the top of the base, and sliders are slidably connected in the slide grooves. A semicircular clamping block is installed on the top of the slider. The two semicircular clamping blocks are connected by fixing bolts, and a first electric telescopic rod is provided between the two semicircular clamping blocks. The thickness detector for building floors in the above-mentioned patent has the following shortcomings: 1. The device lacks a cleaning structure. When it tests the thickness of the floor, the receiver and the transmitter need to cooperate with each other. However, the position below the floor is difficult for the staff to clean. If it is not cleaned, it will affect the accuracy of the detection; 2. The device uses a limit rod and a buffer spring to adapt the installation box to the floor to achieve the purpose of fitting. However, if the floor is uneven, the limit rod slides in a directional manner, and the position of the transmitting probe moved by the limit rod is the position when it preferentially contacts the raised part of the floor. Therefore, there will be data differences in the detection of the concave part of the floor, which affects the detection effect. Utility Model Content

The output end of the motor 5 drives the first driving gear 6 to rotate, thereby the meshing transmission drives the first driven gear 7 to rotate, and then drives the rotating frame 10 to perform a revolution cleaning operation. The top wall of the rotating frame 10 is slidably connected to a moving rod 13. The end of the rotating frame 10 away from the moving rod 13 is fixedly connected to a second driving gear 11, and the second driving gear 11 is meshed and connected with the second driven gear 12. When the rotating frame 10 is revolving, the second driving gear 11 will rotate and mesh and rotate along the second driven gear 12, so as to realize the self-rotation operation of the rotating frame 10 and the brush plate 15.

[0032] Reference Figure 1 and Figure 4 The multi-angle fitting component includes a fixing plate 8 fixedly connected to the top wall of the L-shaped frame 4, and the top wall of the fixing plate 8 is fixedly connected with a symmetrically distributed second strong tension spring 20, and the second strong tension spring 20 is symmetrically arranged in multiple groups to ensure that the installation box 18 of the transmitting probe 19 quickly returns to its position when the extrusion force is lost. The inner wall of the fixing plate 8 is slidably connected with a slide rod 16, and the top wall of the slide rod 16 is rotatably connected with a universal joint 17. The universal joint 17 allows the installation box 18 to be adjusted at multiple angles. The outer wall of the slide rod 16 is sleeved with a first strong tension spring 9. The first strong tension spring 9 cooperates with the slide rod 16 to buffer the impact force of the transmitting probe 19 and avoid damage to the probe.

[0036] Specifically, when the building floor thickness detector is working / in use: first, the base 1 is moved to the position to be tested through the moving wheel 2, and then the electric push rod 3 is started so that the output end drives the L-shaped frame 4 to move upward. At this time, the rotating frame 10 and the brush plate 15 follow the L-shaped frame 4 to move upward, and the initial position of the brush plate 15 is higher than the position of the transmitting probe 19, so the brush plate 15 preferentially contacts the surface of the floor. At this time, the brush plate 15 can appropriately squeeze the floor upward, and its controllable condition is that the brush plate 15 is always higher than the transmitting probe 19. Then the motor 5 is started, and the first driving gear 6 is driven to rotate through the output end of the motor 5, and then the meshing transmission drives the first driven gear 7 to rotate, thereby driving the rotating frame 10, the moving rod 13 and the brush plate 15 to rotate, thereby realizing the revolution cleaning effect, and while the rotating frame 10 is orbiting, its second driving gear 11 will The brush plate 15 is engaged and rotated along the second driven gear 12 to realize the self-rotation operation of the rotating frame 10 and the brush plate 15, thereby enhancing the cleaning effect. After cleaning, the brush plate 15 does not block the transmitting probe 19. Then the output end of the electric push rod 3 continues to push the L-shaped frame 4 to move upward, thereby driving the brush plate 15 and the transmitting probe 19 to move upward. The brush plate 15 can be adaptively extended and retracted through the elastic action of the moving rod 13 and the strong spring 14. When the transmitting probe 19 is squeezed to the floor, if the contact position is uneven, the transmitting probe 19 can be adaptively adjusted in angle through the universal joint 17 under the installation box 18, and pulled by the second strong tension spring 20.
