Description

Technical Field

[0001] This utility model relates to the field of aerated concrete block production technology, specifically to a grouting and compaction device for aerated concrete block production. Background Technology

[0002] Aerated concrete blocks, also known as autoclaved aerated concrete blocks, are a new type of wall material made from stone powder, cement, and lime as the main raw materials. They are prepared by casting, cutting, and curing under high pressure with steam. They are mainly used for non-load-bearing wall construction and frame structure filling. During the production process, aerated concrete blocks require grouting and compaction. Vibration equipment is used to ensure that the grout flows and fills the blocks fully, eliminating air bubbles and ensuring that the grout is dense and full. This enhances the integrity, sealing, and load-bearing capacity of the aerated concrete blocks after molding.

[0003] In the prior art, Chinese Patent Publication No. CN211682657U discloses an air-bubble removal device for aerated concrete blocks, belonging to the technical field of aerated concrete block production equipment. It includes a frame, with a hydraulic cylinder fixedly mounted on the upper end of the frame. A hydraulic rod is installed inside the hydraulic cylinder, extending downwards through the top plate of the frame. A connecting seat is located at the lower end of the hydraulic rod, and multiple sets of concrete vibrators are mounted on the upper end of the connecting seat. Each concrete vibrator includes a motor fixed to the upper end of the connecting seat, with a flexible shaft hose connected to the output end of the motor. This invention controls the downward movement of the hydraulic rod through the hydraulic cylinder, which in turn drives the connecting seat downwards, causing the vibrating vibrator to descend and tamp into the concrete slurry for vibration, eliminating air bubbles inside the slurry, making it denser, and improving product quality. Simultaneously, the simultaneous vibration of multiple sets of vibrators increases production efficiency and avoids the disadvantages of high labor intensity and low production efficiency associated with manual operation.

[0004] However, in actual use, the above solution still has some shortcomings. The motor is directly mounted on the connecting seat, which causes the vibration generated during the operation of the vibrator to be transmitted in reverse to the motor body. This leads to accelerated wear of the motor bearings and loosening of the internal coils and external fixing bolts, thus affecting stability. In addition, the guide column and hydraulic rod are exposed on the outside, and the on-site environment for grouting aerated blocks is dusty. This causes dust to enter the sliding cavity, accelerating the wear of the guide column and hydraulic rod, increasing the sliding friction resistance, and causing the descent to be unsmooth, affecting long-term use. Utility Model Content

[0005] The purpose of this invention is to provide a grouting and compaction device for the production of aerated concrete blocks, so as to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A grouting and compaction device for aerated concrete block production includes a mold frame and a first mounting frame. The mold frame is disposed inside the first mounting frame. A grouting port is provided at the top of the first mounting frame. Two hydraulic cylinders are fixedly mounted on the top of the first mounting frame. The telescopic ends of the two hydraulic cylinders pass through and extend above the mold frame. The telescopic ends of the two hydraulic cylinders are connected to the top of a vibration assembly. Two protective components are fixedly mounted on the top of the vibration assembly. The tops of the two protective components are fixed to the top of the inner wall of the first mounting frame. The telescopic ends of the two hydraulic cylinders are respectively located inside the two protective components. The vibration assembly includes a second mounting frame and several vibrating rods. Each vibrating rod is disposed at the bottom of the second mounting frame. The power connection lines at the top of all the vibrating rods are laid along the inner cavity of the second mounting frame and extend to the outer side of the second mounting frame. The portions of the power connection lines at the top of all the vibrating rods located on the outer side of the second mounting frame are all covered by wire harness protective tubes.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, both of the protective components include two mounting rings and a folding cover. The two mounting rings are respectively fixed to the top of the second mounting bracket and the top of the inner wall of the first mounting bracket by fasteners, and the folding cover is fixedly connected between the two mounting rings.

[0009] Furthermore, the second mounting bracket includes a square tube, a connecting tube, and an X-shaped reinforcing rib. There are two square tubes, two connecting tubes, and two X-shaped reinforcing ribs. The two square tubes are symmetrically distributed front and back. The two connecting tubes and the X-shaped reinforcing ribs are disposed between the two square tubes. The two mounting rings below are fixed to the two X-shaped reinforcing ribs respectively by fasteners.

[0010] Furthermore, connecting blocks are fixedly installed at the bottom of the telescopic ends of both hydraulic cylinders, and the two connecting blocks are respectively fixed to X-shaped reinforcing ribs by fasteners.

[0011] Furthermore, each of the vibrating rods is fixedly mounted with a mounting plate on its top, and each mounting plate is respectively attached to the bottom of two square tubes. The square tubes are fixed to each mounting plate by two bolt assemblies.

[0012] Furthermore, the bolt assembly includes a bolt body, a flat washer, a spring washer, and a nut. The bottom of the bolt body passes through the square tube and the mounting plate and is fixed by the nut. The flat washer and the spring washer are both sleeved on the outside of the bolt body and are located between the nut and the mounting plate.

[0013] Furthermore, rubber pads are provided on both the front and rear sides of the inner walls of the two square tubes.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: The power cable of the vibrator is routed inside the square tube, and the power cable on the outside is protected by a wire harness protection tube. The power cable is connected to an external power source to drive the vibrator. This prevents the vibration generated during operation from affecting the power source. In addition, the folding cover can be adapted to the extension and retraction of the hydraulic cylinder, thereby protecting the extension and retraction end and enabling it to be used for a long time, reducing unnecessary problems.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-6As shown, this utility model provides a grouting and compaction device for aerated concrete block production, including a mold frame 1 and a first mounting frame 2. The mold frame 1 is disposed inside the first mounting frame 2. A grouting port 3 is opened at the top of the first mounting frame 2. Two hydraulic cylinders 4 are fixedly installed at the top of the first mounting frame 2. The telescopic ends of the two hydraulic cylinders 4 penetrate through and extend above the mold frame 1. The telescopic ends of the two hydraulic cylinders 4 are connected to the top of the vibration assembly 5. Two protective components 6 are fixedly installed at the top of the vibration assembly 5. The tops of the two protective components 6 are connected to the top of the first mounting frame 2. The top of the inner wall is fixed, and the telescopic ends of the two hydraulic cylinders 4 are respectively located inside the two protective components 6. The vibrating component 5 includes a second mounting frame 501 and vibrating rods 502. There are several vibrating rods 502, all of which are located at the bottom of the second mounting frame 501. The power connection lines at the top of all vibrating rods 502 are laid along the inner cavity of the second mounting frame 501 and extend to the outside of the second mounting frame 501. The part of the power connection lines at the top of all vibrating rods 502 located outside the second mounting frame 501 is sleeved through the wire harness protection tube 503.

[0019] Under the action of two hydraulic cylinders 4, the second mounting frame 501 is driven to move up and down, so that the vibrating rod 502 enters the interior of the mold frame 1, and the grouting channel can be installed through the grouting port 3 to play a guiding role. Then the vibrating rod 502 is started to compact the grout inside the mold frame 1. The vibratory rod 502 is an electric vibratory rod, and its power connection line is laid inside the second mounting bracket 501 and extends to the outside. It is controlled by the control box, so that the vibratory rod 502 can be started and stopped. The two hydraulic cylinders 4 share a hydraulic pump for oil supply, ensuring consistent flow and pressure, thereby achieving synchronous descent of the telescopic ends.

[0020] Each of the two protective components 6 includes two mounting rings 601 and a folding cover 602. The two mounting rings 601 are fixed to the top of the second mounting bracket 501 and the top of the inner wall of the first mounting bracket 2 respectively by fasteners. The folding cover 602 is fixedly connected between the two mounting rings 601.

[0021] This configuration allows for easy removal of the two mounting rings 601 when maintenance is required. Subsequently, the connection between the telescopic end of the hydraulic cylinder 4 and the second mounting bracket 501 can be disconnected, allowing for maintenance of each component.

[0022] The second mounting bracket 501 includes a square tube 5011, a connecting tube 5012, and an X-shaped reinforcing rib 5013. There are two square tubes 5011, two connecting tubes 5012, and two X-shaped reinforcing ribs 5013. The two square tubes 5011 are symmetrically distributed front and back. The two connecting tubes 5012 and the X-shaped reinforcing ribs 5013 are located between the two square tubes 5011. The two mounting rings 601 below are fixed to the two X-shaped reinforcing ribs 5013 respectively by fasteners.

[0023] This design allows the two square tubes 5011 to facilitate the routing of the power connection cable for the vibrator 502, and the stability of the two square tubes 5011 during use is enhanced by the two connecting tubes 5012 and the two X-shaped reinforcing ribs 5013.

[0024] Among them, the bottom of the telescopic ends of the two hydraulic cylinders 4 are fixedly installed with connecting blocks 7, and the two connecting blocks 7 are fixed to the X-shaped reinforcing ribs 5013 by fasteners respectively.

[0025] With this configuration, the telescopic end of the hydraulic cylinder 4 is fixed to the X-shaped reinforcing rib 5013 under the action of the connecting block 7, so that the hydraulic cylinder 4 can drive the second mounting bracket 501 to move up and down more stably through the X-shaped reinforcing rib 5013 when working.

[0026] All vibrating rods 502 are fixedly mounted with mounting plates 504 on their tops. All mounting plates 504 are respectively attached to the bottom of two square tubes 5011. The square tubes 5011 are fixed to each mounting plate 504 by two bolt assemblies 505. A silicone buffer pad (not shown in the figure) is also provided between the mounting plate 504 and the square tube 5011.

[0027] With this configuration, each vibrator 502 is fixed during installation by two bolt assemblies 505 on the left and right sides, thereby ensuring stability during use and preventing loosening and falling off.

[0028] The bolt assembly 505 includes a bolt body 5051, a flat washer 5052, a spring washer 5053, and a nut 5054. The bottom of the bolt body 5051 passes through the square tube 5011 and the mounting plate 504 and is fixed by the nut 5054. The flat washer 5052 and the spring washer 5053 are both sleeved on the outside of the bolt body 5051 and are located between the nut 5054 and the mounting plate 504.

[0029] This configuration, with a flat washer 5052, a spring washer 5053, and a nut 5054 sequentially installed at the end of the bolt body 5051, leverages the synergistic advantages of the three components: the flat washer increases the force-bearing area between itself and the mounting plate 504, preventing the surface of the mounting plate 504 from being damaged or deformed; the spring washer 5053 utilizes its own elasticity to generate a continuous preload, effectively preventing the nut 5054 from loosening due to vibration, impact, etc., thus addressing the risk of loosening caused by vibration during the operation of the vibrator 502 and significantly improving the overall stability of the connection.

[0030] Rubber pads 8 are provided on both the front and rear sides of the inner wall of the two square tubes 5011.

[0031] With this configuration, when the extension and retraction end of the hydraulic cylinder 4 drives the vibrating assembly 5 to move up and down, the power connection line of the vibrating rod 502 located at the edge of the square tube 5011 is worn less by the rubber pad 8, ensuring long-term use.
