Description

Technical Field

[0002] Autoclaved aerated concrete blocks are a new type of building material that is lightweight, porous, heat-insulating, fire-resistant, and can be nailed, sawed, planed, and has a certain degree of earthquake resistance. As early as the early 1930s, China began to produce this product and it was widely used in high-rise frame structure buildings. In the production of autoclaved aerated concrete blocks, they are generally placed in a mold box for molding. However, due to the long-term use of the mold box, some concrete blocks will stick to the inner wall of the mold box or the inner wall of the mold box will be worn, which will cause the surface of the obtained concrete blocks to be rough and uneven. Therefore, in order to obtain a product with a smooth surface, a certain thickness of the concrete surface needs to be cut off.

[0003] The existing cutting equipment uses taut steel wire to trim the concrete blocks, but in the process of steel wire cutting, the fine particles and slurry of the blocks will be taken away from the cutting surface, and the steel wire surface will produce some tiny uneven places due to friction, and the concrete particles are easy to adhere to these places. As time goes by, the subsequent cutting of the concrete blocks by the steel wire will form scratches on the surface, thereby affecting the quality of the concrete blocks. Secondly, because the steel wire used is relatively thin and the waste has a certain adsorption force, the waste removed after trimming will not fall off immediately and will still stick to the concrete blocks. Therefore, workers are required to handle the waste, which is more troublesome. Summary of the invention

[0033] A rack 10 is fixedly connected to the top of a slider 9 on one side, a slide groove 3 11 is provided on one side of the top of the U-shaped frame 1, an output rod 12 is rotatably connected inside the slide groove 3 11, one end of the output rod 12 is rotatably connected to the inner cavity of the slide groove 2, a gear 13 is fixedly connected to the outer wall of the output rod 12 located in the inner cavity of the slide groove 2, and the gear 13 is matched with the rack 10, a slider 2 15 is slidably connected to the outer wall of the output rod 12, an arc groove 14 is provided on the outer wall of the output rod 12, a guide block 16 is installed on one side of the inner side of the slider 2 15, and the guide block 16 is matched with the arc groove 14;

[0035] The above scheme is adopted: start the motor 15 and drive the two sliders 19 to move downward through the synchronous wheel 7 and the synchronous belt 8. When the slider 19 moves downward, the concrete is cut through the steel wire 46. After the cutting is completed, start the motor 15 to flip and make the slider 19 move upward. When the slider 19 moves upward, the steel wire 46 will contact the compression block 25, so that the compression block 25 slides in the spring groove 23 through the compression of the arc spring 24. At the same time, the steel wire 46 will be stuck in the annular cleaning plate 22. When the steel wire 46 is stuck in the arc spring 24, the rack 10 is engaged with the output rod 12 to drive the gear 13 to rotate. When the gear 13 rotates, the guide block 16 will slide in the arc groove 14 to make the slider 2 15 slide in the slide groove 3 11. The movement of the slider 2 15 can drive the buffer box 17, the connecting block 21 and the annular cleaning plate 22 to move at the same time. The steel wire 46 is stuck in the annular cleaning plate 22 and moves, and the concrete attached to the steel wire 46 can be cleaned through the annular cleaning plate 22.

[0036] When the steel wire 46 is stuck in the annular cleaning plate 22 and moves, the upward force of the slider 9 will cause the limit plate 20 and the connecting block 21 to slide in the buffer groove 18, so that the spring 19 is compressed, so that the annular cleaning plate 22 can always fit the steel wire 46. At the same time, when the slider 9 moves downward, the slider 2 15 can be reset, and the steel wire 46 can be separated from the annular cleaning plate 22.

[0037] like Figures 1 to 11 As shown, a rotating groove 26 is provided on one side of the inner cavity of a set of slide grooves 2, a rack 27 is fixedly connected to the inner cavity of the slide groove 2 close to the rotating groove 26, a connecting plate 28 is fixedly connected to the opposite side of the two sliders 9, and the connecting plate 28 slides in the slide groove 23, a rotating rod 29 is rotatably connected inside the connecting plate 28, and the outer wall of the rotating rod 29 passes through the connecting plate 28 and is fixedly connected to a scraper 30;

[0038] The rotating rod 29 passes through the outer wall of one side of the connecting plate 28 and is fixedly connected with the gear 2 31, and the gear 2 31 is meshed with the rack 27. The rotating rod 29 passes through one end of the connecting plate 28 and is fixedly connected with the limit block 32, and the limit block 32 cooperates with the rack 27. Tooth grooves 33 are provided on both sides of the connecting plate 28 close to the gear 2 31, and the tooth grooves 33 cooperate with the rack 27.

[0039] By adopting the above scheme, when the slider 9 drives the steel wire 46 downward to cut the concrete, it will also drive the connecting plate 28 to move downward, and the cut concrete can be cleaned by the scraper 30, so as to avoid the cut concrete waste from adhering to the concrete;

[0040] When the slider 1 9 moves upward, it will drive the rotating rod 29 to engage with the rack 27 to rotate the scraper 30 ninety degrees, which can prevent the scraper 30 from blocking the steel wire 46 and getting stuck in the annular cleaning plate 22. When the rotating rod 29 rotates, the limit block 32 will also rotate in the rotating groove 26. When the connecting plate 28 moves downward, the limit block 32 will slide in the slide groove 2 3 for limiting, preventing the scraper 30 from rotating when cleaning waste.

[0041] like Figures 1 to 11 As shown, a rack frame 34 is fixedly connected to one side of the top of a set of U-shaped frames 1, and a rack groove 35 is opened inside the rack frame 34, and the rack groove 35 is matched with the rack 10;

[0042] A support rod 36 is fixedly connected to one side of the rack frame 34, and the other end of the support rod 36 is fixedly connected to the U-shaped frame 1;

[0043] The two sets of U-shaped frames 1 are fixedly connected to support bars 37 on both sides, and the upper sides of the support bars 37 are fixedly connected to slide rails 38. The bottom of one side of the two slide rails 38 is fixedly connected to a U-shaped support rod 39, and the inside of the two slide rails 38 is slidably connected to a flatbed trolley 40;

[0044] A waste frame 41 is fixedly connected to the lower part of the opposite side of the two sets of U-shaped frames 1, and a motor 2 42 is installed on one side of the waste frame 41. The output end of the motor 2 42 passes through the waste frame 41 and is rotatably connected to a conveying auger 43;

[0045] The opposite side of the two sets of U-shaped frames 1 close to the chute 2 is fixedly connected with a material blocking plate 44, which is used to block waste from entering the chute 2;

[0046] A cylinder 45 is installed on one side of the two sets of sliders 9, and a steel wire 46 is fixedly connected to the output end of the cylinder 45. One end of the steel wire 46 away from the cylinder 45 is fixedly connected to the slider 9 on the other side.

[0047] With the above solution, when the rack 10 moves upward, it will slide in the rack groove 35 provided inside the rack frame 34, so as to prevent dust from falling into the slide groove 2, and the support rod 36 will make the rack frame 34 more stable;

[0048] The concrete is delivered to the designated location by means of the slide rail 38 and the flatbed trolley 40, and the slide rail 38 is supported by the U-shaped support rod 39 to make the flatbed trolley 40 more stable when moving;

[0049] The waste frame 41 is designed to be two, and the waste scraped by the scraper 30 will fall into the first waste frame 41. The second motor 42 is turned on to transfer the waste collected in the first waste frame 41 to the second waste frame 41 through the conveying auger 43 for cleaning;

[0050] The material blocking plate 44 can prevent scraped waste from entering the chute 2, and the tension of the steel wire 46 can be adjusted by the cylinder 45.

[0051] The working principle and use process of the present invention:

[0052] First, the concrete is transferred to the designated position through the slide rail 38 and the flatbed trolley 40, and then the motor 5 is turned on to drive the two sliders 9 to move downward through the synchronous wheel 7 and the synchronous belt 8. While the slider 9 moves downward, the concrete is cut through the steel wire 46. The tension of the steel wire 46 can be adjusted by the cylinder 45. After the cutting is completed, the motor 5 is turned on to make the slider 9 move upward. When the slider 9 moves upward, the steel wire 46 will contact the compression block 25, so that the compression block 25 slides in the spring groove 23 through the compression of the arc spring 24. At the same time, the steel wire 46 will be stuck in the annular cleaning plate 22. When the steel wire 46 is stuck in the arc spring 24, the rack 10 is meshed with the output rod 12 to drive the gear 13 to rotate. When the wheel 13 rotates, the guide block 16 will slide in the arc groove 14 to make the slider 2 15 slide in the slide groove 3 11. The movement of the slider 2 15 can drive the buffer box 17, the connecting block 21 and the annular cleaning plate 22 to move at the same time. The steel wire 46 is stuck in the annular cleaning plate 22 and the concrete attached to the steel wire 46 can be cleaned by the annular cleaning plate 22. When the steel wire 46 is stuck in the annular cleaning plate 22 and moves, the upward force of the slider 1 9 can make the limit plate 20 and the connecting block 21 slide in the buffer groove 18, so that the spring 19 is compressed, so that the annular cleaning plate 22 can always fit the steel wire 46. At the same time, when the slider 1 9 moves downward, the slider 2 15 can be reset, and the steel wire 46 can be separated from the annular cleaning plate 22.

[0053] When the slider 19 drives the steel wire 46 downward to cut the concrete, it will also drive the connecting plate 28 to move downward, so that the cut concrete can be cleaned by the scraper 30, and the concrete waste after cutting can be prevented from adhering to the concrete. When the slider 19 moves upward, it will drive the rotating rod 29 to engage with the rack 27 to rotate the scraper 30 ninety degrees, so that the scraper 30 can be prevented from blocking the steel wire 46 from being stuck in the annular cleaning plate 22. When the rotating rod 29 rotates, the limit block 32 will also rotate in the rotating groove 26. When the connecting plate 28 moves downward, the limit block 32 will slide in the slide groove 23 to limit the position, so as to prevent the scraper 30 from rotating when cleaning the waste.
