Description

Technical Field

[0001] This utility model relates to aerated concrete segmentation technology, and more specifically, to an aerated concrete block segmentation device. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are a lightweight building material. Their main characteristics include a wide availability of raw materials and advantages over traditional clay bricks, such as sound insulation, heat insulation, fire resistance, and light weight. AAC is made by mixing materials such as lime, cement, and fly ash, which are then aerated and hardened to form a large blank. This blank is then demolded, cut into shape, and finally autoclaved.

[0003] The basic process of autoclaving involves stacking shaped brick blanks layer by layer on a curing cart, then placing them into an autoclave. Inside the autoclave, the blanks undergo high-temperature, high-pressure curing. Once cured, the blanks, along with the curing cart, are pulled out of the autoclave. During curing, the high temperature and pressure environment makes the blanks prone to sticking together. Without separating them, the quality of the finished bricks is affected. To facilitate the separation of the blanks, a series of automatic separating devices have emerged on the market. However, traditional separating devices have low efficiency and cannot meet the ever-increasing production capacity demands. Therefore, how to further improve the efficiency of automatic separating devices is of significant practical importance in production.

[0004] A search revealed a patent in CN218905799U, which discloses a splitting machine capable of splitting multiple layers. In this application, multiple sets of frames at different heights are sequentially arranged on the frame. Lifting power and clamping components connect adjacent sets of frames. The clamping components hold the billet at different heights, and the lifting power drives each layer of frames to change height, thus separating the bonded billets into layers at different heights. This application can simultaneously split multiple layers of billets, reducing splitting time and improving efficiency. However, the application uses a billet lifting method—the lifting device lifts the billet upwards to the splitting position for processing. After splitting, it needs to be lowered back to the starting point and transported to the next station for processing, then transferred to a new billet for the next splitting process. This method, due to the rising and falling of the billet, increases the waiting time for splitting operations, which is detrimental to improving work efficiency. Utility Model Content

[0007] 2. Technical Solution

[0008] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0009] The present invention provides an aerated concrete block splitting device, comprising a frame and a lifting mechanism mounted on the frame. The lifting mechanism is connected to the splitting mechanism and drives the splitting mechanism to move vertically as a whole.

[0010] The splitting mechanism includes a first frame component and a second frame component arranged vertically; wherein the second frame component is connected to a lifting mechanism, and a drive source is provided between the two frame components for driving the first frame component to move vertically independently.

[0011] Both the first frame assembly and the second frame assembly include a pair of clamping beams arranged opposite to each other and clamping elements disposed on the clamping beams;

[0012] The clamping beams are also provided with connecting frames at both ends. The connecting frames have slots, and the slots and the gaps between the two clamping beams together form a channel through which the aerated concrete blank can pass freely.

[0013] In some embodiments, the frame includes a top frame and at least two sets of support components arranged along the length of the top frame, each set of support components including a pair of columns arranged opposite each other;

[0014] The lifting mechanism is mounted on the top frame, and the connecting frame is mounted between the two columns of the support assembly.

[0015] In some embodiments, the first frame assembly is located entirely between the two connecting frames of the second frame assembly, and the connecting frames of the second frame assembly are slidably connected to the support assembly.

[0016] In some embodiments, a synchronization component is provided between the second frame assembly and the support assembly; the synchronization component includes a synchronization shaft and synchronization wheels disposed at both ends of the synchronization shaft, and the column of the support assembly is provided with a rack that meshes with the synchronization wheels.

[0017] In some embodiments, a synchronization component is provided between the first frame assembly and the second frame assembly; the synchronization component includes a synchronization shaft and synchronization pulleys disposed at both ends of the synchronization shaft; wherein,

[0018] The synchronous shaft is mounted on the clamping beam of the first frame assembly; the clamping beam of the second frame assembly is provided with a rack; the rack passes through the clamping beam of the first frame assembly and meshes with the synchronous pulley.

[0019] In some embodiments, the clamping beam is further provided with an adjustment assembly; the adjustment assembly includes a mounting base and an adjustment wheel eccentrically mounted on the mounting base via a connecting shaft, and the frame is provided with a guide bar that cooperates with the adjustment wheel. The adjustment wheel is driven to rotate eccentrically via the connecting shaft to adjust the movement gap between the splitting mechanism and the frame.

[0020] In some embodiments, locking discs are connected to both ends of the connecting shaft, and the locking discs are connected to the mounting base by locking members, and the locking discs are provided with adjustment grooves for the locking members to pass through.

[0021] In some embodiments, the lifting mechanism and drive source are any one of a cylinder, a hydraulic cylinder, or an electric push rod.

[0022] In some embodiments, a conveyor roller conveyor for conveying aerated concrete blanks is provided below the splitting mechanism.

[0023] The method for splitting aerated concrete blocks using the above-mentioned splitting device includes the following steps:

[0024] S1. The aerated concrete billet is moved horizontally by the conveyor rollers to the bottom of the splitting mechanism;

[0025] S2. Keeping the vertical position of the aerated concrete billet unchanged, adjust the vertical position of the splitting mechanism to ensure that the second frame assembly can clamp the lower layer of the aerated concrete billet; while the first frame assembly can clamp the blocks above the lower layer of blocks.

[0026] S3. Start the drive source between the two frame components, so that the first frame component rises, thereby realizing the splitting operation of the two blocks; repeat the above steps S2 and S3, splitting upwards in sequence until the blocks of each layer are split.

[0027] S4. During the descent and reset process of the splitting mechanism, the aerated concrete billet that has been split can move from the channel of the splitting mechanism to the next process; at the same time, the next aerated concrete billet to be split can move through the channel of the splitting mechanism to the bottom of the splitting mechanism for the next splitting.

[0028] 3. Beneficial effects

[0029] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0030] (1) The present invention provides an aerated concrete block splitting device. By optimizing the specific structure of the splitting mechanism, a channel can be formed on the splitting mechanism for the aerated concrete block to pass through freely. In this way, during the descent of the splitting mechanism, the aerated concrete block that has been split can exit the splitting station simultaneously, while the next aerated concrete block to be processed can enter the splitting station simultaneously, thereby greatly saving waiting time and improving work efficiency.

[0031] (2) The aerated concrete block splitting device of this utility model has an eccentrically installed adjusting wheel, which can adjust the movement gap between the splitting mechanism and the frame by rotating the adjusting wheel, thereby improving the stability of the device operation.

[0032] (3) The aerated concrete block splitting device of this utility model is provided with a synchronization component between the second frame component and the support component and the first frame component. The synchronization component adopts a gear and rack structure, which can effectively ensure the stability and accuracy of the splitting mechanism during the lifting process.

[0033] (4) The present invention provides a method for splitting aerated concrete blocks, which employs a splitting mechanism that is raised and lowered as a whole, while the aerated concrete block remains stationary in the vertical direction. During the raising and lowering of the splitting mechanism, since there is a channel on the splitting mechanism for the aerated concrete block to pass through freely, the aerated concrete block can move horizontally simultaneously to enter and leave the splitting station, thereby greatly reducing the waiting time and improving the splitting efficiency.

[0049] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0050] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] Traditional aerated concrete (ACC) block splitting devices have two main drawbacks. First, they require lifting and lowering the ACC block, during which other actions cannot be performed, thus prolonging the waiting time. Second, traditional ACC block splitting devices typically employ a fully enclosed structure, where the frame of the splitting device covers the entire ACC block during the splitting process. The biggest drawback of this structure is that when the ACC block moves horizontally into or out of the splitting station, the splitting device must be lifted or the ACC block lowered to prevent the frame from obstructing it. In other words, after splitting, one must wait for the splitting device to be lifted or the ACC block to be lowered to a suitable position before the ACC block can be moved in or out. This also prolongs the waiting time, thus hindering work efficiency. Therefore, this invention aims to provide an ACC block splitting device that reduces the waiting time during the splitting process, thereby improving splitting efficiency.

[0052] The present invention will be further described below with reference to specific embodiments.

[0053] like Figure 1 As shown, an aerated concrete block splitting device according to this embodiment includes a frame 100 and a lifting mechanism 200 and a splitting mechanism 300 disposed on the frame 100. The frame 100 includes a top frame 110 and at least two sets of support components 120 disposed along the length of the top frame 110. Each set of support components 120 includes a pair of opposing columns. The lifting mechanism 200 is disposed on the top frame 110; the splitting mechanism 300 is disposed between the two columns of the support components 120 and moves vertically as a whole under the drive of the lifting mechanism 200.

[0054] like Figure 2 As shown, the splitting mechanism 300 includes a first frame assembly 310 and a second frame assembly 320 arranged vertically. A lifting mechanism 200 is connected to the second frame assembly 320 and drives the entire splitting mechanism 300 to move vertically. Simultaneously, a drive source is provided between the first frame assembly 310 and the second frame assembly 320 to drive the first frame assembly 310 to move independently in the vertical direction.

[0055] Specifically, both the lifting mechanism 200 and the drive source utilize existing technologies, such as cylinders, hydraulic cylinders, or electric actuators. No specific limitations are imposed here. Meanwhile, three sets of support assemblies 120 are provided, one set at each end and one set in the middle of the top frame 110.

[0056] Additionally, it should be noted that although the splitting mechanism 300 in this embodiment only includes two frame components, in order to simultaneously split multi-layer aerated concrete blocks, the splitting mechanism 300 can be configured with three or more frame components, and a drive source is provided between each pair of adjacent frame components.

[0057] like Figure 3 , Figure 4 As shown, the first frame assembly 310 and the second frame assembly 320 have basically the same structure, both including a pair of clamping beams 311 arranged opposite each other and clamping members 312 arranged on the clamping beams 311. Of course, a gap must be left between the two clamping beams 311 to accommodate the aerated concrete blank 400. The clamping member 312 can be formed by a cylinder / hydraulic cylinder with a telescopic rod, or directly by an electric push rod; no specific limitation is made here. When the aerated concrete blank 400 is located in the gap between the pair of clamping beams 311, the clamping members 312 on both sides move towards each other to clamp the aerated concrete blank 400; then, the first frame assembly 310 is driven upwards individually by a drive source to complete one splitting action. (For details, please refer to CN218905799U)

[0058] Meanwhile, connecting frames 313 are provided at both ends of the clamping beams 311, and slots are opened on the connecting frames 313. The slots and the gaps between the two clamping beams 311 together form a channel 314 through which the aerated concrete blank 400 can pass freely. That is to say, the connecting frame 313 has an inverted U-shaped structure and is set vertically on the clamping beams 311. The two free ends of the connecting frame 313 are each located on one of the clamping beams 311.

[0059] Furthermore, the first frame assembly 310 is entirely located between the two connecting frames 313 of the second frame assembly 320, and the connecting frames 313 of the second frame assembly 320 are slidably connected to the support assembly 120. See details for further information. Figure 7 As shown, a slide rail 316 is provided on the inner side wall of the support assembly 120 (i.e., on the side wall opposite to a set of columns), and a slider 315 that cooperates with the slide rail 316 is provided on the outer side wall of the connecting frame 313.

[0060] This embodiment of an aerated concrete block splitting device employs a splitting mechanism 300 that is raised and lowered as a whole, while the aerated concrete block 400 remains stationary in the vertical direction. Simultaneously, through optimized design of the specific structure of the splitting mechanism 300, a channel 314 is formed on the splitting mechanism 300 for the aerated concrete block 400 to pass freely. Thus, during the descent of the splitting mechanism 300, the split aerated concrete block 400 can simultaneously leave the splitting station, while the next aerated concrete block 400 to be processed can simultaneously enter the splitting station, thereby significantly saving waiting time and improving work efficiency.

[0061] like Figure 2 , Figure 8 As shown, in some embodiments, a synchronization component 330 is provided between the second frame assembly 320 and the support assembly 120. The synchronization component 330 includes a synchronization shaft 331 and synchronization wheels 332 disposed at both ends of the synchronization shaft 331. There are two synchronization shafts 331, located on the outer sides of the corresponding clamping beams 311. Meanwhile, a rack 333 that meshes with the synchronization wheels 332 is provided on the column of the support assembly 120. Thus, when the lifting mechanism 200 drives the splitting mechanism 300 to move up and down, the stability and accuracy of the overall movement of the splitting mechanism 300 can be ensured through the cooperation between the rack 333 and the synchronization wheels 332.

[0062] Similarly, a synchronization component 330 may also be provided between the first frame component 310 and the second frame component 320. Specifically, refer to Figure 9 As shown, the synchronization component 330 includes a synchronization shaft 331 and synchronization pulleys 332 disposed at both ends of the synchronization shaft 331. The synchronization shaft 331 is mounted on the clamping beam 311 of the first frame assembly 310. Meanwhile, a rack 333 is provided on the clamping beam 311 of the second frame assembly 320, which passes through the clamping beam 311 of the first frame assembly 310 and meshes with the synchronization pulleys 332. In this embodiment, the cooperation between the rack 333 and the synchronization pulleys 332 ensures the stability and accuracy of the first frame assembly 310 when it moves independently.

[0063] In some embodiments, an adjustment assembly 340 is further provided between the splitting mechanism 300 and the frame 100. Specifically, refer to... Figure 3 , Figure 5 , Figure 10As shown, the adjustment assembly 340 includes a mounting base 341 and an adjustment wheel 343 eccentrically mounted on the mounting base 341 via a connecting shaft 342. Meanwhile, the frame 100 is provided with a guide bar 346 that cooperates with the adjustment wheel 343. Of course, an annular groove is provided on the adjustment wheel 343 for the guide bar 346 to engage. In this way, the connecting shaft 342 can drive the adjustment wheel 343 to rotate eccentrically, which can be used to adjust the movement clearance between the splitting mechanism 300 and the frame 100, further ensuring the stability of the entire device operation.

[0064] Furthermore, the mounting base 341 is a semi-enclosed structure with an opening on one side. The connecting shaft 342 is located inside the cavity of the mounting base 341, and both ends of the connecting shaft 342 pass through the opposite sidewalls of the mounting base 341 and are connected to locking discs 344. The locking discs 344 and the mounting base 341 are connected by locking elements 345, such as locking bolts. At the same time, an arc-shaped adjustment groove 3441 is provided on the locking discs 344 for the locking elements 345 to pass through. In this way, when the locking elements 345 are loosened, the connecting shaft 342 can be rotated by the locking discs 344, which in turn drives the adjusting wheel 343 to rotate eccentrically. The resulting deviation can be used to adjust the size of the fit clearance between the adjusting wheel 343 and the guide bar 346. Subsequently, the locking discs 344 can be locked by the locking elements 345 to prevent the splitting mechanism 300 from swinging during the lifting process due to excessive fit clearance.

[0065] like Figure 6 As shown, in some embodiments, a conveyor roller 500 is provided below the splitting mechanism 300 to facilitate the horizontal conveying of the aerated concrete billet 400.

[0066] The working process of the aerated concrete block splitting device in this embodiment is as follows:

[0067] S1. The aerated concrete billet 400 is moved horizontally by the conveyor roller 500 to the bottom of the splitting mechanism 300. Since the splitting mechanism 300 is provided with a channel 314 for the aerated concrete billet 400 to pass through freely, the splitting mechanism 300 can be lowered to the working position in advance to reduce the waiting time.

[0068] S2. Keeping the vertical position of the aerated concrete blank 400 unchanged, the vertical position of the splitting mechanism 300 is finely adjusted to ensure that the second frame assembly 320 can clamp the lower layer of the aerated concrete blank 400; while the first frame assembly 310 can clamp the blocks above the lower layer of blocks.

[0069] S3. Start the drive source between the two frame components, so that the first frame component 310 rises, thereby realizing the splitting operation between the two blocks; repeat the above steps S2 and S3, splitting upwards in sequence until the blocks of each layer are split.

[0070] S4. During the resetting process of the splitting mechanism 300, the currently split aerated concrete billet 400 can move from the channel 314 of the splitting mechanism 300 to the next process; at the same time, the next aerated concrete billet 400 to be split can move through the channel 314 of the splitting mechanism 300 to the area below the splitting mechanism 300 for the next splitting. In other words, during the resetting process of the splitting mechanism 300, the aerated concrete billet 400 can be replaced in the horizontal direction, thereby further reducing the waiting time.

[0071] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
