[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Referring to Figures 2 - 4 , an embodiment provided by the present invention: A special device for construction project quality inspection, including a support frame 1. A transportation component is installed inside the support frame 1, and the transportation component can convey the construction materials to be inspected into the device for inspection when the device is started. In the middle of the top of the support frame 1, there is a fixedly connected mounting frame 6. On both sides of the top of the mounting frame 6, there are fixedly connected hydraulic cylinders 7. The output end of the hydraulic cylinder 7 is fixedly connected with a mounting plate 8. A flaw detector 9 is installed in the middle of the mounting plate 8. By starting the hydraulic cylinder 7, the mounting plate 8 is pushed downward, so that the flaw detector 9 in the middle of the mounting plate 8 can contact the material, and then the material is detected by the ultrasonic wave emitted by the flaw detector 9. After the detection is completed, the mounting plate 8 is pulled up by the hydraulic cylinder 7 to separate the flaw detector 9 from the material, facilitating the detection of the next material. On both sides of the top of the support frame 1, there are fixedly connected limiting frames 10. A movable arm 11 is slidably connected inside the limiting frame 10. There is a connecting rod 12 between the movable arm 11 and the mounting plate 8. A hook 13 is rotatably connected inside the side of the movable arm 11 away from the connecting rod 12. A limiting plate 14 is fixedly connected to the end of the movable arm 11 away from the connecting rod 12. Start the hydraulic cylinder 7 to drive the mounting plate 8 to move up, so that the flaw detector 9 is separated from the bottom material that has been detected. At the same time, as the mounting plate 8 moves up, it will pull the connecting rod 12 connected to it. Through the connecting rod 12, the movable arm 11 is pulled to move inside the limiting frame 10 towards the direction of the mounting frame 6. At this time, the movable arm 11 will also pull the hook 13 to move. Since the side of the hook 13 is blocked by the limiting plate 14, the hook 13 cannot flip in the reverse direction of the limiting plate 14. Then the hook 13 will pull the transportation component to start running, so that the transportation component can drive the construction materials to move and convey the construction materials to be inspected below the flaw detector 9.

[0034] Referring to Figure 1 , Figure 3 and Figure 4, a suction assembly is installed on the middle side of the top of the mounting frame 6, a connecting frame 15 is fixedly connected to one side of the mounting plate 8, a nozzle 16 is fixedly connected to the bottom of the connecting frame 15, and a dust suction port 17 is fixedly connected to the other side of the mounting plate 8. The suction assembly can blow out high-pressure gas from the nozzle 16, and then clean the dust and impurities on the surface of the material to be tested, and at the same time, the blown flying dust can be sucked and collected from the inside of the dust suction port 17 to prevent the dust from attaching to the material again. The transportation assembly includes a plurality of rollers 2, which are rotatably connected to the inside of the support frame 1, and a plate conveyor belt 3 is sleeved between the outer sides of the plurality of rollers 2. The traction sleeve 4 is fixedly connected to both sides of the outer side of the plate conveyor belt 3, and the outer periphery of the traction sleeve 4 is provided with a plurality of equally spaced slots 5. The inner wall of one side of the slot 5 is in a vertical state, and abuts against the side of the hook 13 away from the limit plate 14. The inner wall of the other side of the slot 5 is sloped, so that the hook 13 can be separated from the inside of the slot 5 when resetting. The hook 13 pulls the slot 5 to drive the traction sleeve 4 to move, and then the traction sleeve 4 can drive the plate conveyor belt 3 to rotate and move on the outside of the roller 2, and transport the construction materials on the plate conveyor belt 3 to the bottom of the flaw detector 9 for quality inspection. The bottom of the hook 13 is engaged with the inside of one of the slots 5, and the limit plate 14 and the hook 13 are in contact, so that when the movable arm 11 pulls the hook 13, it can ensure that the hook 13 pulls the slot 5 to drive the traction sleeve 4 to move. When resetting, due to the lack of the limit plate 14 on the hook 13, the hook 13 will flip toward the direction of the mounting frame 6 and leave the inside of the slot 5. One end of the connecting rod 12 is hinged to the bottom edge of the mounting plate 8, and the other end of the connecting rod 12 is hinged to the side of the top of the movable arm 11 away from the limit plate 14. The movable arm 11 and the mounting plate 8 are connected by the connecting rod 12, so that the equipment can drive the transportation component to run while detecting the material, and transport the material to the bottom of the flaw detector 9. The outer side of the traction sleeve 4 is in contact with the inner side of the support frame 1, and the mounting plate 8 is slidably connected to the inner side of the mounting frame 6, so that when the hook 13 pulls the slot 5 to drive the traction sleeve 4 to move, the traction sleeve 4 and the inner side of the support frame 1 are tightly fitted to ensure that the traction sleeve 4 can remain still when it stops, avoiding movement due to inertia, and at the same time ensuring that the hydraulic cylinder 7 can stably drive the mounting plate 8 to move up and down.

[0035] Reference Figure 1 , Figure 3 and Figure 5The suction assembly includes a filter box 18 and a cylinder 19. The bottom of the filter box 18 is fixedly connected to one side of the middle of the mounting frame 6, and the bottom of the cylinder 19 is fixedly connected to the other side of the middle of the mounting frame 6. Two one-way valves 20 are installed on the top of the cylinder 19. The inside of one of the one-way valves 20 is connected to the top of the filter box 18 through a pipeline, and the bottom of the filter box 18 is connected to the inside of the dust suction port 17 through a pipeline. When the mounting plate 8 moves down with the flaw detector 9 to detect the material, the movable rod 22 will pull the piston 21 to move downward, and the space on the upper side of the cylinder 19 is in a negative pressure state. At this time, suction is generated inside the cylinder 19, so that the outside air carries the dust that has just been blown up and enters the dust suction port 17, and then the air carries the dust along the pipeline into the filter box 18. At this time, the dust in the air will be blocked and remain inside the filter box 18, and the air passes through the filter box 18 through the pipeline and enters the cylinder 19 from the side of the one-way valve 20, and then absorbs and collects the raised dust to prevent the dust from attaching to the surface of the material again. Another one-way valve 20 is connected to the inside of the nozzle 16 through a pipeline, and a piston 21 is slidably connected inside the cylinder 19, and a movable rod 22 is set between the piston 21 and the mounting plate 8. As the mounting plate 8 moves upward, the movable rod 22 and the piston 21 will be pushed upward, so that the piston 21 will squeeze the gas in the upper space inside the cylinder 19, so that these gases will be discharged through the one-way valve 20 at the top, and enter the nozzle 16 along the pipeline, and then the high-pressure gas will be blown out through the nozzle 16. The top of the movable rod 22 is fixedly connected to the middle of the piston 21, and the bottom of the movable rod 22 passes through the mounting frame 6 and is fixedly connected to the top of the mounting plate 8, so that the device can realize the simultaneous work of detection, transportation and cleaning when it is started. An exhaust hole 23 is opened at the bottom of the outer periphery of the cylinder 19. When the piston 21 moves downward, it will not be unable to move downward due to the sealing of the bottom of the cylinder 19, so that the normal operation of the suction assembly is realized.

[0036] Working principle: Place the construction materials to be detected on the plate conveyor belt 3, and separate the materials in sequence through the partitions distributed on the plate conveyor belt 3. Subsequently, start the hydraulic cylinder 7 to drive the mounting plate 8 to move upward, so that there is a separation between the flaw detector 9 and the bottom of a detected material. At the same time, as the mounting plate 8 moves upward, it will pull the connecting rod 12 connected to it, and through the connecting rod 12, pull the movable arm 11 to move inside the limit frame 10 in the direction of the mounting frame 6. At this time, the movable arm 11 will also pull the hook 13 to move. Since the side of the hook 13 is blocked by the limit plate 14, the hook 13 cannot flip in the reverse direction of the limit plate 14. Then the movable arm 11 can pull the card slot 5 through the hook 13, and then the traction sleeve 4 and the plate conveyor belt 3 can move outside the idler 2. The construction materials are conveyed through the plate conveyor belt 3 until the mounting plate 8 moves to the highest point. At this time, the connecting rod 12 pulls the movable arm 11 to move to the maximum stroke, and the hook 13 will drive the traction sleeve 4 and the plate conveyor belt 3 to move a specified length of distance through the traction card slot 5. At this time, the previously detected material leaves the bottom of the flaw detector 9, and the next material to be detected is conveyed to the bottom of the flaw detector 9. At this time, the hydraulic cylinder 7 pushes the mounting plate 8 to move downward, so that the flaw detector 9 contacts the material for flaw detection. As the mounting plate 8 moves downward, it will push the connecting rod 12 and the movable arm 11 to reset. Since there is no limit on the side of the hook 13 away from the limit plate 14, the hook 13 will be rotated upward by the inner wall of the card slot 5, and then the hook 13 will disengage from the inside of the card slot 5. As the mounting plate 8 moves downward to the original detection height, at this time the movable arm 11 pushes the hook 13 to reset to the initial position, and at this time the hook 13 is above the next card slot 5. Subsequently, the hook 13 flips and drops and is caught inside the next card slot 5 to be pulled. By running in this way, the materials can be continuously and accurately conveyed under the flaw detector 9, so that the equipment can continuously detect the quality of the materials and ensure that each material can be detected.

[0037] When the device starts up and transports materials for detection, as the mounting plate 8 moves upward, it will push the movable rod 22 and the piston 21 upward, causing the piston 21 to squeeze the gas in the upper space inside the cylinder body 19. These gases will be discharged through the one-way valve 20 at the top and enter the nozzle 16 along the pipeline, and then the high-pressure gas will be blown out through the nozzle 16. At the same time, as the mounting plate 8 moves upward, it will pull the transportation component to transport the materials to the lower part of the flaw detector 9. At this time, the materials will move past the bottom of the nozzle 16, so that the dust and impurities attached to the surface of the materials during stacking and transportation can be blown off by the gas ejected inside the nozzle 16 until the blowing stops when the materials move to the lower part of the flaw detector 9. Ensure that there are no other external factors interfering when the flaw detector 9 contacts the materials. When the mounting plate 8 moves downward and drives the flaw detector 9 to detect the materials, at this time the movable rod 22 will pull the piston 21 to move downward, and the space on the upper side inside the cylinder body 19 is in a negative pressure state. At this time, a suction force is generated inside the cylinder body 19, causing the external air to carry the just-blown flying dust into the dust suction port 17. Subsequently, the air carrying the dust enters the filter box 18 along the pipeline. At this time, the dust in the air will be blocked and remain inside the filter box 18, while the air passes through the filter box 18 and enters the cylinder body 19 through the one-way valve 20 on the side through the pipeline, and then adsorbs and collects the raised dust to prevent the dust from adhering to the surface of the materials again. And the air inhaled into the cylinder body 19 will be compressed by the piston 21 later and then blown out to clean the materials.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
