[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] Referring to Figures 1 and 2, one embodiment of this utility model provides a prefabricated building engineering quality inspection device, including a support plate 1. A first fixing plate 101 is fixedly connected to the upper surface of the support plate 1. An electric push rod 102 is fixedly connected to the right outer wall of the first fixing plate 101. A first rack 103 is fixedly provided at the output end of the electric push rod 102. A gear body 104 is meshed with the tooth end of the first rack 103. A rotating shaft 105 is fixedly connected to the inner wall of the gear body 104. The outer wall of the rotating shaft 105 is rotatably connected to... A limiting bracket 106 is provided, the left outer wall of the limiting bracket 106 is fixedly connected to the right outer wall of the first fixing plate 101, the outer wall of the rotating shaft 105 is fixedly connected to an extension bracket 107, the upper surface of the bearing plate 1 is fixedly connected to a second fixing plate 108, the rear outer wall of the extension bracket 107 is fixedly connected to a sliding plate 109, the outer wall of the sliding plate 109 is slidably connected to the inner wall of the bearing plate 1, the left outer wall of the sliding plate 109 is slidably connected to the right outer wall of the second fixing plate 108, and the lower surface of the bearing plate 1 is provided with a bearing component.
[0027] Specifically, activating the electric push rod 102 fixed on the first fixed plate 101 pushes the first rack 103 to move, causing the gear body 104 to rotate. The gear body 104 drives the rotating shaft 105 to rotate on the inner wall of the limiting bracket 106, causing the extension bracket 107 to unfold. The extension bracket 107 drives the sliding plate 109 to slide on the inner wall of the bearing plate 1, so that the sliding plate 109 and the sliding plate 109 clamp the concrete. This component can achieve the effect of avoiding the movement of concrete during testing and affecting the test results.
[0028] Referring to Figures 1 and 3, the support assembly includes a worktable 2. The upper surface of the worktable 2 is fixedly connected to the lower surface of the support plate 1. Rollers 201 are fixedly connected to the lower surface of the worktable 2. A brush 202 is fixedly connected to the lower surface of the worktable 2. A support bracket 203 is fixedly connected to the upper surface of the brush 202. A slide rail 204 is fixedly connected to the inner top wall of the support bracket 203. A slider 205 is slidably connected to the outer wall of the slide rail 204. A detection head 206 is fixedly connected to the lower surface of the slider 205. A lifting assembly is provided on the outer wall of the worktable 2.
[0029] Specifically, the rollers 201 on the lower surface of the workbench 2 facilitate the movement of the entire unit. The bearing support 203, slide rail 204 and slider 205 allow the detection head 206 to be moved according to the size of the concrete for detection. When the lifting assembly flips and the concrete falls, the brush 202 cleans the surface of the load block 310 during the flipping process.
[0030] Referring to Figures 1, 4, and 5, the lifting assembly includes a base plate 3. The inner wall of the base plate 3 is fixedly connected to the outer wall of the worktable 2. A motor 301 is fixedly connected to the upper surface of the base plate 3. A worm gear 302 is fixedly installed at the output end of the motor 301. The tooth end of the worm gear 302 is meshed with a worm wheel 303. A lead screw 304 is fixedly connected to the inner wall of the worm wheel 303. The lower surface of the lead screw 304 is rotatably connected to the upper surface of the base plate 3. A moving block 305 is threadedly connected to the outer wall of the lead screw 304. A limit shell 306 is slidably connected to the outer wall of the moving block 305. A base 307 is fixedly connected to the lower surface of the limit shell 306. The inner wall of the base 307 is rotatably connected to the outer wall of the lead screw 304, and the inner wall of the moving block 305 is rotatably connected to the sector gear 308; the tooth end of the sector gear 308 is meshed with the second rack 309, and the lower surface of the second rack 309 is fixedly connected to the upper surface of the base 307; the outer wall of the sector gear 308 is fixedly connected to the carrying block 310, the outer wall of the carrying block 310 is slidably connected to the inner wall of the workbench 2, the outer wall of the carrying block 310 is slidably connected to the outer wall of the bearing plate 1, the outer wall of the carrying block 310 is slidably connected to the outer wall of the brush 202, and the upper surface of the base 3 is fixedly connected to the waste frame 311.
[0031] Specifically, the motor 301 fixed on the base plate 3 drives the worm gear 302 to rotate, which in turn drives the worm wheel 303 to rotate. The worm wheel 303 drives the lead screw 304 to rotate, causing the moving block 305 to slide in the inner wall of the limiting shell 306. The moving block 305 drives the sector gear 308 to move, which in turn moves the load block 310. Due to the second rack 309 fixed on the base 307, when the moving block 305 descends to a certain height, it will cause the load block 310 to flip, thereby pouring the tested concrete into the waste box 311. This component can achieve the effect of preventing residues from affecting the next test results.
[0032] Working principle: When the device is needed, the roller 201 first moves the entire assembly. After the assembly is in place, the operator places an appropriate amount of concrete on the load block 310. The electric push rod 102, fixed on the first fixed plate 101, pushes the first rack 103 to move smoothly, causing the gear body 104 to rotate. Simultaneously, the rotation of the gear body 104 drives the rotating shaft 105 to rotate smoothly along the inner wall of the limiting bracket 106, causing the extension bracket 107 to extend smoothly. The extension bracket 107 pushes the sliding plate 109 to slide smoothly along the inner wall of the bearing plate 1. At the same time, the second fixed plate 108 works in conjunction to clamp the concrete. This assembly can prevent concrete movement during testing from affecting the test results, thus improving the stability and reliability of the test results. By moving the slider 205 along the outer wall of the slide rail 204, the detection head 206 accurately detects the concrete. After the test is completed... The motor 301, fixed on the base plate 3, is started, driving the worm gear 302 to rotate, which in turn causes the worm wheel 303 to rotate. The rotation of the worm wheel 303 drives the lead screw 304 to rotate, causing the moving block 305 to slide smoothly on the inner wall of the limiting shell 306. This allows the sector gear 308 to stably drive the load block 310 to move. When the moving block 305 slides to a certain height, the load block 310 is flipped through the cooperation of the sector gear 308 and the second rack 309, thus pouring the tested concrete into the waste frame 311, achieving the effect of automatic collection. At the same time, since a brush 202 is provided on the lower surface of the workbench 2, it can clean the surface of the load block 310 during the flipping, thereby achieving the effect of cleaning the residue on the surface of the load block 310. Using this device can, on the one hand, avoid the movement of concrete during testing from affecting the test results, and on the other hand, avoid the residue from affecting the results of the next test.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
