Description

Technical Field

[0001] This utility model relates to the field of concrete slab thickness detection technology, specifically to a device for detecting the thickness of autoclaved aerated concrete slabs. Background Technology

[0002] Autoclaved aerated concrete (AAC) panels are a lightweight, porous, and environmentally friendly building material made primarily from cement, lime, and silica sand, with varying amounts of corrosion-resistant steel mesh added according to structural requirements. After processing, the thickness of the AAC panels needs to be tested, and substandard products are rejected to ensure they meet factory requirements. For example, application number "202322125300.X" describes an AAC panel thickness testing device, which includes a conveyor support with several conveyor rollers rotating on it.

[0003] However, although it can detect the thickness of autoclaved aerated concrete slabs, it requires separate detection and transportation of thinner and thicker concrete slabs at two locations, resulting in poor efficiency. Furthermore, the need for two sets of equipment for detecting and sorting thinner and thicker concrete slabs leads to higher costs and potential for control chaos. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the device requires inspection and transportation of thinner and thicker concrete slabs at two different locations, resulting in poor efficiency. Furthermore, the need to use two sets of equipment for inspection and sorting of thinner and thicker concrete slabs leads to high costs and potential control chaos. Therefore, this invention proposes a device for detecting the thickness of autoclaved aerated concrete slabs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A thickness detection device for autoclaved aerated concrete (AAC) slabs is designed, comprising a base and a support. The support is fixedly connected to the upper rear side of the base, and a lifting cylinder is fixedly connected to the upper front end of the support. A sleeve is fixedly connected to the output shaft of the lifting cylinder. A laser detection head is fixedly connected to the inner wall of the sleeve. An adjustment component is installed on the outer wall of the laser detection head. A material pushing component is provided on the rear side of the AAC slab.

[0007] This feature involves installing a lifting cylinder at the top of the bracket to move the laser detection head to different heights, ensuring sufficient space below for placing the concrete slab. The laser detection head then detects the actual distance between the laser detection head and the reflecting surface by measuring the duration of laser beam emission and reception.

[0008] Preferably, the adjustment component includes a motor bracket, which is fixedly connected to one side of the outer wall of the sleeve. A servo motor is fixedly connected to the upper end of the outer wall of the motor bracket. A gear one is fixedly connected to the output shaft of the servo motor, and a gear two is meshed with the outer wall of the gear one.

[0009] This setting, through component design adjustment, allows the entire pushing assembly to rotate sequentially to the left, front, and right sides under the action of the servo motor, achieving the purpose of one pushing assembly being applicable to three pushing angles.

[0010] Preferably, a smooth plane is fixed to the upper center of the base, and a concrete slab is placed on top of the smooth plane.

[0011] This design incorporates a smooth surface, allowing the concrete slab to move quickly and with reduced wear when the pusher assembly pushes it.

[0012] Preferably, the outer wall of the base has smooth inclined surfaces fixedly connected to both ends and the center of the front side, and the rear ends of the sleeve are slidably connected to slide rails, with the rear ends of the slide rails fixedly connected to the bracket.

[0013] This setup allows for the placement of three conveyor structures below, corresponding to three locations with smooth ramps, to handle the different discharge processes of concrete slabs of three different structures.

[0014] Preferably, the pushing assembly includes a cylinder bracket, the inner wall of which is rotatably connected to the outer wall of the laser detection head via a bearing, the upper end of the outer wall of the cylinder bracket is fixedly connected to a gear, a self-locking cylinder is fixedly connected to the front end of the cylinder bracket, a push plate is fixedly connected to the end of the output shaft of the self-locking cylinder, a slide rod is slidably connected to the inner wall above the push plate, both ends of the slide rod are fixedly connected to the cylinder bracket, and a groove is machined on the inner wall of the output shaft of the self-locking cylinder.

[0015] This feature utilizes a self-locking cylinder to move a push plate, which in turn moves the concrete slab, pushing it to different smooth slopes depending on the specific structure being tested.

[0016] Preferably, the base has support feet fixed at the four corners of its lower end, and a button is installed on the right side of the front end of the base.

[0017] This setting button can be used to control the start and stop of the entire device. The support feet raise the height between the device and the surface it is placed on, ensuring good heat dissipation.

[0018] The autoclaved aerated concrete (AAC) slab thickness detection device proposed in this utility model has the following advantages:

[0019] Through the coordination of the servo motor, gear one, gear two, cylinder bracket, push plate, smooth inclined plane, and self-locking cylinder, the servo motor, through the design of gear one and gear two, drives the cylinder bracket to rotate on the outer wall of the laser detection head, causing the push plate to rotate to the opposite side of the corresponding smooth inclined plane. At this time, the three smooth inclined planes correspond to different conveyor lines for qualified, thicker, and thinner concrete slabs, respectively. Then, by controlling the output shaft of the self-locking cylinder to retract, the push plate is driven to move the concrete slab to the corresponding smooth inclined plane, and finally slides down the inclined plane to the corresponding conveyor line for transportation. This effectively avoids the problem of poor efficiency caused by having to inspect and transport the thinner and thicker concrete slab structures at two different locations.

[0020] Through the coordination between the servo motor, gear one, gear two, cylinder bracket, and self-locking cylinder, and through the design of the servo motor and gears one and two, the servo motor can control the cylinder bracket and self-locking cylinder to adjust the corresponding angle settings according to the measurement results. This allows a single pusher structure design to handle the pusher requirements of three types of concrete slabs with measurement results of qualified, thicker, and thinner concrete slabs. This effectively avoids the problems of high cost and easy control chaos caused by using two sets of equipment for the detection and sorting of thinner and thicker concrete slabs.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] See attached document Figure 1-6 In this embodiment, an autoclaved aerated concrete (AAC) slab thickness detection device includes a base 1 and a support 2. The support 2 is fixedly connected to the upper rear side of the base 1, and a lifting cylinder 6 is fixedly connected to the upper front end of the support 2. A sleeve 8 is fixedly connected to the output shaft of the lifting cylinder 6, and a laser detection head 5 is fixedly connected to the inner wall of the sleeve 8. The laser detection head 5 can emit and receive laser beams and measure the distance between the laser beam and the emitting surface by the time difference between the two. The specific model can be determined according to the specific application. An adjustment component 3 is installed on the outer wall of the laser detection head 5. A pushing component 4 is provided on the rear side of the AAC slab 11. The AAC slab 11 is an autoclaved aerated concrete (AAC) slab, which is a lightweight, porous, new type of green and environmentally friendly building material made of cement, lime, silica sand, etc. as the main raw materials and with different amounts of anti-corrosion treated steel mesh added according to structural requirements.

[0030] A smooth plane 12 is fixedly connected to the upper center of the base 1. A concrete slab 11 is placed on top of the smooth plane 12. Smooth inclined planes 13 are fixedly connected to the left and right ends and the center of the front side of the outer wall of the base 1. The smooth plane 12 and the smooth inclined plane 13 have low surface roughness and are smoother, which facilitates the sliding of the concrete slab 11 on its surface. Support feet 9 are fixedly connected to the four corners of the lower end of the base 1. A button 10 is installed on the right side of the front end of the base 1. The opening of the equipment can be controlled by the button 10. The two sides of the rear end of the sleeve 8 are slidably connected to the slide rail 7. The rear end of the slide rail 7 is fixedly connected to the bracket 2.

[0031] See attached document Figure 1-6 In this embodiment, the adjustment component 3 includes a motor bracket 302, which is fixedly connected to one side of the outer wall of the sleeve 8. A servo motor 303 is fixedly connected to the upper end of the outer wall of the motor bracket 302. The model of the servo motor 303 can be determined according to the specific application. It has a self-locking capability. A gear 1 301 is fixedly connected to the output shaft of the servo motor 303. A gear 2 304 is meshed with the outer wall of the gear 1 301.

[0032] See attached document Figure 1-6In this embodiment, the pushing assembly 4 includes a cylinder bracket 401. The inner wall of the cylinder bracket 401 is rotatably connected to the outer wall of the laser detection head 5 via a bearing. The upper end of the outer wall of the cylinder bracket 401 is fixedly connected to a gear 304. A self-locking cylinder 403 is fixedly connected to the front end of the cylinder bracket 401. The self-locking cylinder 403 is a multi-stage self-locking cylinder, and the specific model can be determined according to the specific application. A push plate 402 is fixedly connected to the end of the output shaft of the self-locking cylinder 403. A slide rod 405 is slidably connected to the inner wall above the push plate 402. Both ends of the slide rod 405 are fixedly connected to the cylinder bracket 401. A groove 404 is machined on the inner wall of the output shaft of the self-locking cylinder 403. The groove 404 provides space for the laser beam of the laser detection head 5 to pass through and be received, and does not affect the extension and retraction process of the output shaft of the self-locking cylinder 403.

[0033] Working principle:

[0034] When this autoclaved aerated concrete (AAC) slab thickness detection device is needed, firstly, according to the size (i.e., thickness) of the AAC slab to be detected, the lifting cylinder 6 is controlled to adjust the height of the laser detection head 5, so that there is sufficient space below the laser detection head 5 for placing the AAC slab to be detected, i.e., concrete slab 11. Then, the laser detection head 5 is controlled to emit a laser, and the distance between the laser detection head 5 and the smooth surface 12 is calculated by receiving the reflected light. Next, the AAC slab to be detected is placed on the smooth surface 12, and the laser detection head 5 is controlled to emit a laser again, and the reflected light is received by the AAC slab to be detected. The distance between the laser detection head 5 and the AAC slab to be detected is calculated. The result of the second measurement can be transmitted to an external computer via a signal line. The specific thickness of the concrete slab 11 can be obtained by subtracting the data.

[0035] By comparing the measured thickness of the concrete slab 11 with the corresponding required thickness, three results can be obtained: qualified, thicker, and thinner. These three results can be used to start the corresponding servo motor 303 (which can be controlled by a PLC control circuit). The servo motor 303, through the design of gear 1 301 and gear 2 304, drives the cylinder bracket 401 to rotate on the outer wall of the laser detection head 5, causing the control push plate 402 to rotate to the opposite side of the corresponding smooth inclined surface 13 (at this time, the push plate 402 is not in contact with the concrete slab 11 but is at its farthest limit position, and will not rotate during rotation). (Interference occurs). At this time, the three smooth inclined planes 13 correspond to different conveyor lines for qualified, thicker, and thinner concrete slabs 11, respectively. Then, by controlling the output shaft of the self-locking cylinder 403 to retract, the push plate 402 is driven to move the concrete slab 11 to the corresponding smooth inclined plane 13, and finally slides down the inclined plane to the corresponding conveyor line for transportation. This effectively avoids the problem of poor efficiency caused by having to inspect and transport the thinner and thicker concrete slab structures at two different locations. After the push plate 402 pushes the material, the self-locking cylinder 403 controls the push plate 402 to reset.

[0036] Furthermore, through the design of the servo motor 303 and gears 301 and 304, the servo motor 303 can control the cylinder support 401 and the self-locking cylinder 403 to adjust the corresponding angle settings according to the measurement results. This allows the use of a single pusher structure design to handle the pusher requirements of three types of concrete slabs 11 with measurement results of qualified, thicker, and thinner concrete slabs. This effectively avoids the problem of high cost and easy control chaos caused by using two sets of equipment for the detection and sorting of thinner and thicker concrete slabs.
