Description

Technical Field

[0001] This utility model relates to the field of UHPC wall panel technology, and specifically to a device for detecting surface damage of UHPC wall panels. Background Technology

[0002] UHPC wall panels, short for Ultra-High Performance Concrete Wall Panels, are a new type of building material with high strength, high durability, and high seismic performance. UHPC wall panels are widely used in building exterior walls, interior partitions, roofs, and floors, and are particularly suitable for places with high requirements for wall panel performance, such as high-rise buildings, bridges, and tunnels.

[0003] To ensure structural safety, UHPC wall panels need to undergo surface damage testing to promptly identify and address potential hazards, prevent further damage, and ensure the safety of the building structure.

[0004] Traditional methods for detecting surface damage in UHPC wall panels rely on manual visual inspection by workers, which is labor-intensive and inefficient. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model proposes a device for detecting surface damage of UHPC wall panels, including a roller conveyor and a belt conveyor. The transport direction of the roller conveyor is perpendicular to the transport direction of the belt conveyor, and the belt conveyor is at the same height as the roller conveyor. A detection camera for detecting surface damage of UHPC wall panels during transport is provided above the roller conveyor. A sorting component is provided on the roller conveyor to feed damaged UHPC wall panels into the belt conveyor.

[0006] To achieve the above objectives, a roller conveyor is used to transport UHPC wall panels to be inspected. When the panels pass by the inspection camera, the camera takes a picture of them so that staff can determine whether there is any damage to the surface of the UHPC wall panels. Undamaged UHPC wall panels can be collected smoothly by passing through the roller conveyor. Damaged UHPC wall panels pass through the sorting component, which pushes them onto an adjacent belt conveyor. The belt conveyor provides power to transport them to the appropriate location, effectively improving inspection efficiency.

[0007] Furthermore, the sorting assembly includes a mounting platform fixed to the side of the roller conveyor, an electric push rod fixed on the mounting platform, a push plate located above the roller conveyor fixed to the extended end of the electric push rod, a guide block fixed on the electric push rod, a guide rod slidably connected inside the guide block via a slide rail, one end of the guide rod extending out of the guide block, and the end of the guide rod extending out of the guide block being fixed to the push plate.

[0008] The above technical solution uses an electric push rod to provide power, which drives the push plate to move. The push plate allows the damaged UHPC wall panel to enter the belt conveyor. The guide block guides and supports the movement of the guide rod, and the guide rod guides and limits the movement of the push plate, thereby improving the stability of the push plate's movement.

[0009] Furthermore, the roller conveyor is equipped with a speed reduction component to control the moving speed of the UHPC wall panel in order to improve observation efficiency.

[0010] With the above technical solution, several UHPC wall panels move on the roller conveyor, and the time it takes for them to pass the inspection camera is also short, resulting in low inspection efficiency. By setting a speed reduction component, the inspection time is increased and the inspection accuracy is improved.

[0011] Furthermore, the speed reduction assembly includes a support plate fixed to the roller conveyor, on which four short shafts are rotatably connected. Each short shaft has a gear nested around it and fixed coaxially with it. The four gears mesh with each other. Two of the short shafts located on the sides extend upward and are higher than the roller conveyor. At the ends of the two short shafts that extend above the roller conveyor, a first baffle plate and a second baffle plate are respectively fixed. Both the first baffle plate and the second baffle plate are higher than the roller conveyor. A first motor that drives one of the short shafts to rotate is fixed on the support plate.

[0012] Through the above technical solution, the first motor provides power to drive one of the short shafts fixed coaxially with the output shaft to rotate. The rotation of the short shaft will drive the gear fixed coaxially with the short shaft to rotate. The rotation of the gear will drive the other gears meshing with the gear to rotate. The two gears located on the side rotate towards each other, which facilitates the rotation of the first baffle plate and the second baffle plate, so as to realize the work of blocking and separating materials.

[0013] Furthermore, one of the short shafts extends downward and through the support plate, and a swing arm is fixed to the portion of the short shaft that extends out of the support plate. Ear plates located on both sides of the roller conveyor are also fixed on the roller conveyor, with one of the ear plates close to the swing arm.

[0014] With the above technical solution, when the motor provides power and drives the four short shafts to rotate, it drives the swing arm fixed to the short shafts to rotate. When the swing arm rotates to the point of contacting the adjacent ear plate, the ear plate plays a limiting role.

[0015] Furthermore, the roller conveyor has three trays for pushing the UHPC wall panels to a suitable straightening rod, and a control component for controlling the movement of the straightening rod is provided between the two ear plates.

[0016] With the above technical solution, the UHPC wall panels entering the roller conveyor are placed in a tray of appropriate size. Power is provided by the control component to drive the straightening rod to move and push the tray to a suitable position. When the tray moves directly under the detection camera, all the UHPC wall panels can be observed.

[0017] Furthermore, the control assembly includes a screw disposed between two ear plates and rotatably connected to the ear plates. Guide rods are provided on both sides of the screw, and both ends of the guide rods are fixed to the adjacent ear plates. A slider threadedly connected to the screw is sleeved on the screw. The slider is sleeved outside the guide rod and slidably connected to the guide rod. The bottom end of the straightening rod that protrudes from the roller is fixed with a slider. A second motor that drives the screw to rotate is fixed on one of the ear plates.

[0018] Through the above technical solution, the second motor provides power to drive the screw fixed coaxially with the output shaft of the second motor to rotate. The rotation of the screw will drive the slider connected to the screw thread to move. The guide rod guides the movement of the slider. The movement of the slider will drive the straightening rod fixed to the slider to move, thereby pushing the tray to the appropriate position.

[0019] In summary, the device for detecting surface damage in UHPC wall panels has the following beneficial effects:

[0020] (1) The device for detecting surface damage of UHPC wall panels uses a roller conveyor to transport the UHPC wall panels to be tested. When the UHPC wall panels pass the detection camera, the detection camera takes pictures of them so that the staff can determine whether there is damage on the surface of the UHPC wall panels. UHPC wall panels without damage can be collected smoothly by passing through the roller conveyor. When UHPC wall panels with damage pass through the sorting component, the sorting component pushes the UHPC wall panels onto the adjacent belt conveyor. The belt conveyor provides power to transport them to the appropriate position, which effectively improves the detection efficiency.

[0021] (2) The device for detecting surface damage of UHPC wall panels is powered by a first motor, which drives one of the short shafts fixed coaxially with the output shaft to rotate. The rotation of the short shaft will drive the gear fixed coaxially with the short shaft to rotate. The rotation of the gear will drive the other gears meshing with the gear to rotate. The two gears located on the side rotate towards each other, which facilitates the rotation of the first baffle plate and the second baffle plate, so as to realize the work of blocking and separating materials.

[0022] (3) The UHPC wall panel surface damage detection device that enters the roller conveyor is placed in a tray of appropriate size. The control component provides power to drive the correction rod to move and push the tray to a suitable position so that when the tray moves directly under the detection camera, all UHPC wall panels can be observed.

[0030] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0031] like Figure 1-5 As shown, a preferred embodiment of this utility model provides a device for detecting surface damage to UHPC wall panels, comprising a roller conveyor 1 and a belt conveyor 2. The transport direction of the roller conveyor 1 is perpendicular to the transport direction of the belt conveyor 2. The belt conveyor 2 is at the same height as the roller conveyor 1. Above the roller conveyor 1 is a detection camera 3 for detecting surface damage to UHPC wall panels during transport. The detection camera 3 is fixed on a frame located outside the roller conveyor 1. A lighting lamp located next to the detection camera 3 and providing a light source is also fixed on the frame. The roller conveyor 1 is equipped with a sorting assembly 4 for feeding damaged UHPC wall panels into the belt conveyor 2.

[0032] like Figure 1Roller conveyor 1 is used to transport UHPC wall panels to be inspected. When passing the inspection camera 3, the inspection camera takes a picture of the UHPC wall panel so that the staff can determine whether there is any damage on the surface of the UHPC wall panel. UHPC wall panels without damage can pass smoothly through roller conveyor 1 and be collected. When UHPC wall panels with damage pass through sorting component 4, the sorting component 4 pushes the UHPC wall panel onto the adjacent belt conveyor 2. The belt conveyor 2 provides power to transport the UHPC wall panel to the appropriate position, which effectively improves the inspection efficiency.

[0033] like Figure 1 and Figure 3 The sorting assembly 4 includes a mounting platform 401 fixed to the side of the roller conveyor 1. An electric push rod 402 is fixed on the mounting platform 401. A push plate 403 located above the roller conveyor 1 is fixed to the extended end of the electric push rod 402. The center line of the push plate 403 is parallel to the center line of the belt conveyor 2. A guide block 404 is also fixed on the electric push rod 402. A guide rod 405 is slidably connected inside the guide block 404 through a slide rail. One end of the guide rod 405 extends out of the guide block 404, and the end of the guide rod 405 extending out of the guide block 404 is fixed to the push plate 403.

[0034] like Figure 1 and Figure 3 The electric push rod 402 provides power to drive the push plate 403 to move. The push plate 403 allows the damaged UHPC wall panel to enter the belt conveyor 2. The guide block 404 guides and supports the movement of the guide rod 405, and the guide rod 405 guides and limits the movement of the push plate 403, thereby improving the stability of the push plate 403.

[0035] like Figure 1 and Figure 2 In order to reduce the possibility of several trays containing UHPC wall panels getting too close to each other and affecting the entry of the trays into the belt conveyor 2, and also to improve the observation accuracy, the roller conveyor 1 is equipped with a speed reduction component 5 to control the moving speed of the UHPC wall panels to improve the observation efficiency.

[0036] like Figure 1 and Figure 2The speed reduction assembly 5 includes a support plate 501 fixed on the roller conveyor 1. Four short shafts 502 are rotatably connected to the support plate 501. Each short shaft 502 is fitted with a gear 503 that is coaxially fixed with the short shaft 502. The four gears 503 mesh with each other. Two of the short shafts 502 located on the side extend upward and are higher than the roller conveyor 1. At the ends of the two short shafts 502 that are higher than the roller conveyor 1, a first baffle plate 504 and a second baffle plate 505 are respectively fixed. Both the first baffle plate 504 and the second baffle plate 505 are higher than the roller conveyor 1. The first baffle plate 504 has an L-shaped cross section, and the second baffle plate 505 has a Z-shaped cross section. A first motor that drives one of the short shafts 502 to rotate is fixed on the support plate 501.

[0037] like Figure 1 and Figure 2 The first motor provides power to drive one of the short shafts 502, which is fixed coaxially with the output shaft, to rotate. The rotation of the short shaft 502 will drive the gear 503, which is fixed coaxially with the short shaft 502, to rotate. The rotation of the gear 503 will drive the other gears 503 meshing with the gear 503 to rotate. The two gears 503 located on the side rotate towards each other, which facilitates the rotation of the first baffle plate 504 and the second baffle plate 505, so as to realize the work of blocking material and powder.

[0038] like Figure 1 and Figure 2 One of the short shafts 502 extends downward and passes through the support plate 501. The part of the short shaft 502 that passes through the support plate 501 is fixed with a swing rod 506. The roller conveyor 1 is also fixed with ear plates 6 located on both sides of the roller conveyor 1. One of the ear plates 6 is close to the swing rod 506. When the motor provides power and drives the four short shafts 502 to rotate, it drives the swing rod 506 fixed to the short shaft 502 to rotate. When the swing rod 506 rotates to the point of contacting the adjacent ear plate 6, the ear plate 6 plays a limiting role.

[0039] like Figure 1 and Figure 4 and Figure 5 The roller conveyor 1 has three trays for pushing UHPC wall panels to the appropriate straightening rod 7. A control component 8 is provided between the two ear plates 6 to control the movement of the straightening rod 7. The UHPC wall panels entering the roller conveyor 1 are placed in the trays of appropriate size. The control component 8 provides power to drive the straightening rod 7 to move and push the tray to the appropriate position so that when the tray moves to the position directly under the inspection camera 3, all UHPC wall panels can be observed.

[0040] like Figure 1 and Figure 4 and Figure 5The control component 8 includes a screw 801 disposed between two ear plates 6 and rotatably connected to the ear plates 6. Guide rods 802 are provided on both sides of the screw 801. Both ends of the guide rods 802 are fixed to the adjacent ear plates 6. A slider 803 threadedly connected to the screw 801 is sleeved on the screw 801. The slider 803 is sleeved on the guide rods 802 and slidably connected to the guide rods 802. The bottom end of the straightening rod 7 that protrudes from the roller is fixed with the slider 803. A second motor 804 that drives the screw 801 to rotate is fixed on one of the ear plates 6.

[0041] like Figure 1 and Figure 4 and Figure 5 The second motor 804 provides power to rotate the screw 801, which is coaxially fixed with the output shaft of the second motor 804. The rotation of the screw 801 will drive the slider 803, which is threadedly connected to the screw 801, to move. The guide rod 802 guides the movement of the slider 803. The movement of the slider 803 will drive the straightening rod 7, which is fixed to the slider 803, to move, thereby pushing the tray to the appropriate position.

[0042] When in use, connect the power supply, turn on the switch, put the UHPC wall panel to be tested into the tray, place the UHPC wall panel containing the tray on the roller conveyor 1, and drive the tray containing the UHPC wall panel to move towards the inspection camera 3 through the power provided by the roller conveyor 1.

[0043] When the tray passes the straightening rod 7, the second motor 804 provides power to drive the screw 801, which is coaxially fixed with the output shaft of the second motor 804, to rotate. The rotation of the screw 801 will drive the slider 803, which is threadedly connected to the screw 801, to move. The movement of the slider 803 will drive the straightening rod 7, which is fixed with the slider 803, to move. The straightening rod 7 moves and pushes the tray to the appropriate position.

[0044] A cylinder is fixed to the upper surface of the pallet, cooperating with the first baffle plate 504 and the second baffle plate 505. There is a certain gap between every two adjacent cylinders. The first baffle plate 504 and the second baffle plate 505 are higher than the pallet and aligned with the cylinders. The cylinder on the first pallet after passing the straightening rod 7 is blocked by the first baffle plate 504. At this time, the second baffle plate 505 is located beside the roller conveyor 1 and does not contact the cylinder on the second pallet. At this time, the UHPC wall panel inside the pallet is inspected by the inspection camera 3 to observe whether it is damaged. After the inspection is completed, the first motor is turned on, and the first motor provides power to drive the gear 503 fixed coaxially with the output shaft of the first motor to rotate. The four gears 503 mesh with each other, driving the other gears 503 to rotate. The rotation of the four gears 503 will drive the gears fixed to the gears 503 to rotate. The short shaft 502 rotates, thereby causing the first baffle plate 504 to rotate without contacting the cylinder of the first pallet and without affecting the movement of the first pallet on the roller conveyor 1. The second baffle plate 505 rotates and contacts the cylinder on the second pallet, and resists the continuous movement of the pallet. After the first pallet moves out of the range of motion of the first baffle plate 504, the first motor drives the gear 503 to rotate, thereby driving the second baffle plate 505 and the first baffle plate 504 to rotate back to their initial positions. The second baffle plate 505 does not affect the movement of the second pallet. The second pallet moves to the side of the first baffle plate 504. The first baffle plate 504 rotates and contacts the cylinder of the second pallet. At this time, the UHPC wall panel in the second pallet is inspected. The above operation is repeated, so that several pallets move intermittently, improving the accuracy of damage detection.

[0045] Undamaged UHPC wall panels can be smoothly collected by roller conveyor 1. Damaged UHPC wall panels pass through push plate 403, and electric push rod 402 is activated. The electric push rod 402 provides power to move push plate 403. Push plate 403 allows the damaged UHPC wall panels to enter belt conveyor 2. Guide block 404 guides and supports the movement of guide rod 405, and guide rod 405 guides and limits the movement of push plate 403, improving the stability of push plate 403 movement. Powered by belt conveyor 2, the panels are transported to the appropriate position, effectively improving the detection efficiency.

Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention.
