Description

Technical Field

[0001] This utility model relates to a device for detecting hollow tiles, belonging to the field of construction engineering technology. Background Technology

[0002] Currently, floor tiles are widely used in various construction projects as building floor decoration materials. However, due to factors such as construction techniques, material quality, and environmental conditions, hollow spots are prone to occur after floor tile installation, meaning there are localized or large-area gaps between the floor tiles and the substrate. Hollow spots not only cause cracks and warping on the surface of the floor tiles, affecting their aesthetics and lifespan, but may also pose safety hazards when pedestrians walk on them. To detect hollow spots in floor tiles, the industry has developed various devices. For example, Chinese utility model patent CN216433991U discloses a floor tile hollow spot detection vehicle, specifically including a chassis, L-shaped handlebars, a switch button, rubber wheels, side fixing plates, an infrared level, a control box, a motor, an infrared analyzer, a sound wave analyzer, a rotating shaft, a telescopic rod, and a sound wave detection ball; the L-shaped handlebars are equipped with a switch button to control the operation of the infrared level. The detection of hollow spots in floor tiles is achieved by setting up a corresponding hammering mechanism to hammer the floor tiles, and the hollow spots are determined by distinguishing the sounds. After detecting hollow tiles, this type of equipment usually requires manual calibration. If the test results are not recorded manually in a timely manner, the subsequent positioning and treatment of hollow tiles may be inaccurate due to delayed or missed markings, thus posing a risk of missed detection.

[0006] The aforementioned tile hollow detection device includes a drive mechanism comprising a rotating shaft symmetrically arranged below the frame and a first mounting base arranged below the frame; the rotating shaft is provided with a plurality of second gears, which mesh externally with a first gear on the same side and on the same vertical plane; the first mounting base is provided with a first motor, the output end of which is connected to a third gear, which meshes externally with the second gears on the rotating shafts on both sides respectively.

[0007] The aforementioned tile hollow detection device has baffles located on the outside of the feed trough and discharge trough at the upper and lower ends of the second mounting base, respectively.

[0008] The aforementioned tile hollow detection device includes a buffer mechanism comprising guide rods symmetrically arranged at the lower end of a movable frame, the guide rods being slidably connected to the movable frame; an installation rod is connected between the guide rods, and an impact block is disposed at the lower middle end of the installation rod; a spring is provided between the installation rod and the movable frame, surrounding the outside of the guide rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, the vehicle frame is moved by tracked wheels. During the movement, the striking mechanism periodically strikes the floor tiles. Simultaneously, a sound-receiving device collects the sound signals generated by the striking of the floor tiles in real time and transmits them to the control board. Upon receiving a signal indicating an abnormal sound, the control board sends a signal to the physical marker placement mechanism, which immediately triggers the marking process: the upper and lower grooves of the turntable align with the feed chute and discharge chute, respectively, causing the calibration block in the feed chute to fall into the upper groove. When marking is required, a second motor drives the turntable to rotate 180°, aligning the upper groove carrying the calibration block with the lower discharge chute. The calibration block slides down the lower discharge chute under gravity onto the floor tile surface to complete the marking. At this time, the original lower groove rotates to the upper groove, and another calibration block automatically falls into the upper groove, entering the next placement ready state. Thus, this utility model achieves the effect of calibrating detected hollow floor tiles by placing calibration blocks, and has the advantages of simple structure and prevention of missed marking.

[0015] 2. In this utility model, the striking mechanism, driven by the drive mechanism, rotates the first gear. The protrusion fixed on the first gear rotates synchronously with the gear, and through its cooperation with the waist-shaped groove on the moving frame, drives the moving frame to reciprocate in the vertical direction, realizing the periodic striking of the floor tile by the impact block. The buffer mechanism absorbs the impact force, preventing the floor tile from cracking due to excessive striking force. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0024] Example: A device for detecting hollow tiles, comprising as follows Figure 1-6 As shown, the vehicle includes a frame 1 made of lightweight aluminum alloy. Symmetrically arranged on both sides of the frame 1 are highly elastic rubber track wheels 2, whose anti-slip texture enhances friction with the ground, adapting to various ground surfaces and slope environments. A control box 3 is located above the frame 1, containing a control board. The control board is a PCBA board, integrating a processor and electronic components such as capacitors and resistors. The processor can be an MCU. Since the control board is a common component in this field and commercially available, its specific structure and circuit connections will not be described in detail here. As a further preferred embodiment, a lidar box 7 and a display screen 8 are located on the top of the frame 1. The lidar box 7 and display screen 8 are connected to the control board via wiring. The lidar box 7 emits multi-beam lasers and receives reflected signals from the environment, enabling real-time detection of surrounding obstacles for obstacle avoidance and inspection. This technology is a commonly used and mature technology in this field, so specific details will not be elaborated here. The display screen 8 is used to display the number of detected voids in real time. A drive mechanism 4 is provided below the frame 1; multiple striking mechanisms 5 are symmetrically arranged on both sides below the frame 1, and the striking mechanisms 5 are connected to the drive mechanism 4; a physical marker delivery mechanism 6 fixedly connected to the frame 1 is provided on the side of the striking mechanism 5; such as Figure 4As shown, the striking mechanism 5 is equipped with a sound receiving device 9 connected to the control board. In this embodiment, the sound receiving device 9 is a microphone. The physical tag delivery mechanism 6 includes a second mounting base 60 fixedly connected to the frame 1. The rear end of the second mounting base 60 is equipped with a second motor 61 connected to the control board. The output end of the second motor 61 passes through the second mounting base 60 and is connected to a turntable 62. The upper part of the second mounting base 60 is equipped with a feeding groove 63, in which a calibration block 64 is placed. Further, when the calibration block 64 is located in the feeding groove 63, the upper end is equipped with an adhesive substance. The adhesiveness should not be too strong, just enough to make the calibration block 64 stick to the floor tile and not move due to light touch. The lower part of the second mounting base 60 is equipped with a discharge groove 67. The turntable 62 is symmetrically equipped with grooves 65. The rotation of the grooves 65 drives the calibration block 64 from the feeding groove 63 to the discharge groove 67 and discharges it. The chassis 1 is moved by the tracked wheels 2. During movement, the striking mechanism 5 periodically strikes the floor tiles. Simultaneously, the sound receiving device 9 collects the sound signals generated by the striking of the floor tiles in real time and transmits them to the control board. The processor on the control board determines whether the sound frequency collected by the sound receiving device reaches a threshold. If the threshold is reached, a signal is sent to the physical marker placement mechanism 6, which immediately triggers the marking process: the upper and lower grooves 65 of the turntable 62 align with the feed chute 63 and the discharge chute 67 respectively, causing the calibration block 64 in the feed chute 63 to fall into the upper groove 65. When marking is required, the second motor 61 drives the turntable 62 to rotate 180°, aligning the upper groove 65 carrying the calibration block 64 with the lower discharge chute 67. Under gravity, the calibration block 64 slides down the discharge chute 67 onto the floor tile surface to complete the marking. At this time, the original lower groove 65 rotates to the upper side, and another calibration block 64 automatically falls into the upper groove 65, entering the next placement ready state.

[0025] Preferably, such as Figure 3 As shown, the striking mechanism 5 includes a mounting bracket 50 fixedly connected to the frame 1. A first gear 51 is rotatably connected to the mounting bracket 50. A protruding post 52 is provided on the central side of the first gear 51, and a limiting plate 521 is provided on the outer side of the protruding post 52 to prevent the waist-shaped groove of the movable frame 53 from separating from the protruding post 52 during movement. A movable frame 53 is slidably connected to the mounting bracket 50. A horizontally placed waist-shaped groove 54 is provided on the movable frame 53, and the protruding post 52 slides laterally back and forth in the waist-shaped groove 54. A buffer mechanism 55 is provided below the movable frame 53. An impact block 59 is provided at the lower end of the buffer mechanism 55. Further, the impact block 59 is a omnidirectional ball, so as to adapt to terrains at different angles. Figure 6As shown, the upper and lower sides of the waist-shaped groove 54 are respectively provided with V-shaped inclined grooves 541. The V-shaped inclined grooves 541 change the force direction of the protrusion 52, making the movement process smoother. The movable frame 53 includes a sliding part 531, which is inverted T-shaped. The upper end of the sliding part 531 is slidably connected to the first mounting base 41. The waist-shaped groove 54 is provided at the lower end of the sliding part 531. A U-shaped part 532 is fixedly connected below the sliding part 531 and is slidably connected to the guide rod 56. The U-shaped part 532 is provided with a slot 533 located above the guide rod 56, through which the extension and retraction of the guide rod 56 can be observed. The striking mechanism 5, driven by the driving mechanism 4, drives the first gear 51 to rotate. The protrusion 52 fixed on the first gear 51 rotates synchronously with the gear. Through its cooperation with the waist-shaped groove 54 on the moving frame 53, it drives the moving frame 53 to reciprocate in the vertical direction, realizing the periodic impact of the impact block 59 on the floor tile. The impact force is absorbed by the buffer mechanism 55 to prevent the floor tile from cracking due to excessive impact force.

[0026] Preferably, such as Figure 2 and Figure 4 As shown, the drive mechanism 4 includes a rotating shaft 40 symmetrically arranged below the frame 1 and a first mounting base 41 arranged below the frame 1. The rotating shaft 40 is equipped with multiple second gears 42, which mesh externally with a first gear 51 on the same side and on the same vertical plane. The first mounting base 41 is equipped with a first motor 43, the output end of which is connected to a third gear 44, which meshes externally with the second gears 42 on both sides of the rotating shaft 40. The drive mechanism 4 causes the third gear 44 to rotate via the first motor 43. The third gear 44 rotates by meshing with the second gears 42 on both sides, thereby causing the rotating shafts 40 on both sides to rotate. After the rotating shafts 40 rotate, they mesh with the first gear 51 via the second gears 42, causing the striking mechanism 5 to operate.

[0027] Preferably, such as Figure 4 As shown, the upper and lower ends of the second mounting base 60 are respectively connected to baffle plates 66 located outside the feed trough 63 and the discharge trough 67. The baffle plates 66 effectively prevent the calibration block 64 from falling off due to vibration during equipment movement.

[0028] Preferably, such as Figure 3As shown, the buffer mechanism 55 includes guide rods 56 symmetrically arranged at the lower end of the movable frame 53, with the guide rods 56 slidably connected to the movable frame 53; a mounting rod 57 is connected between the guide rods 56, and an impact block 59 is located at the lower middle end of the mounting rod 57; a spring 58 is provided between the mounting rod 57 and the movable frame 53, surrounding the outside of the guide rods 56. When the buffer mechanism 55 strikes the floor tiles under the drive of the movable frame 53, if the striking force is excessive, the guide rods 56 overcome the resistance of the spring 58 and slide into the movable frame 53, compressing the spring 58 to absorb the impact energy. When the movable frame 53 rises, the spring 58 releases its elastic potential energy, driving the guide rods 56 to move downwards and reset, ensuring that the striking force is controlled within a safe range each time.

[0029] Preferably, such as Figure 4 As shown, the turntable is provided with an indicator groove 68, and the angle between the indicator groove 68 and the groove 65 is 90°; the second mounting base is provided with indicator points 69 on both sides. By checking whether the indicator groove 68 is aligned with the indicator point 69, it can be visually seen whether the groove 65 is aligned with the discharge groove 67 and the feed groove 63.

[0030] Working principle:

[0031] First, the track wheels 2 drive the chassis 1 to move at a constant speed. Simultaneously, the lidar box 7 on top of the chassis 1 emits multi-beam lasers and receives environmental reflection signals for obstacle avoidance and inspection. The display screen 8 shows the number of hollow tiles detected in real time. During the movement of the chassis 1, the drive mechanism 4 drives the first gear 51 of the striking mechanism 5 to rotate via gear transmission. Its side protrusion 52 rotates with the gear and engages with the waist-shaped groove 54 of the moving frame 53, causing the moving frame 53 to reciprocate vertically. This causes the lower impact block 59 to periodically strike the floor tiles. If the striking force is too great, the guide rod 56 of the buffer mechanism 55 will compress the spring 58 to absorb the impact and protect the floor tiles. After the moving frame 53 rises, the spring 58 releases its elastic potential energy to drive the guide rod 56 to reset. At the same time, the sound receiving device 9 on the striking mechanism 5 collects the sound signal of the floor tiles being struck in real time and transmits it to the control unit. The control board inside the box 3 performs spectrum analysis on the signal using a built-in algorithm. Based on the difference in vibration frequency between normal and hollow floor tiles, it accurately determines whether there is a hollow area. If a hollow area is detected, the second motor 61 of the physical marker placement mechanism 6 drives the turntable 62 to rotate 180°, so that the calibration block 64 in the upper groove 65 rotates with the turntable 62 until it is aligned with the discharge chute 67. Under the action of gravity, the calibration block 64 slides down the discharge chute 67 onto the surface of the floor tile to complete the marking. At this time, the original lower groove 65 rotates to the upper part and is aligned with the feed chute 63. Another calibration block 64 automatically falls into the groove 65 to await the next placement.
