Description

Technical Field

[0001] This invention relates to the field of aerated concrete production technology, specifically to a lifting platform, an aerated concrete production line, and a method for mixing bricks. Background Technology

[0002] When producing ALC blocks and panels, the finished aerated concrete blocks formed after the steam curing process typically have a rectangular cross-section of 1.2m × 0.6m. To facilitate storage and transportation, two batches of aerated concrete blocks are usually combined to make their cross-section 1.2m × 1.2m; this process is commonly referred to as stacking. If blocks that are not fully stacked to a length × width of 1.2m × 1.2m are transferred on subsequent pallets, the blocks are prone to tipping over and being damaged.

[0003] Currently, lifting platforms are installed on the billet conveying line. The lifting frame of the platform goes straight up and down. When the blocks are not aligned or misaligned, the lifting frame is prone to tipping or knocking over the blocks when it is raised and lowered. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the lifting frame is prone to tipping or knocking over blocks during the lifting process when the blocks are misaligned or misplaced, thereby providing a lifting platform, an aerated concrete production line and a method for piling blocks.

[0005] To address the aforementioned problems, the present invention provides a lifting platform, comprising: a mounting frame; a lifting frame, which is movably mounted on the mounting frame and is adapted to carry a blank; and a lifting drive component, which is mounted on and connected to the lifting frame, and drives the lifting frame to move horizontally while simultaneously lifting it.

[0006] Optionally, the lifting platform may also include a lifting and translating mechanism, which includes a swinging component. The swinging component is hinged to the drive end of the mounting frame, the lifting frame, and the lifting drive component. The lifting drive component drives the swinging component to swing, thereby driving the lifting frame to move up and down and horizontally.

[0007] Optionally, the swinging component includes an active swinging component and a driven swinging component, which are connected to the opposite sides of the lifting frame. The number of lifting drive components is one. The lifting and translation mechanism also includes a connecting rod, one end of which is hinged to the active swinging component and the other end of which is hinged to the driven swinging component. The driving end of the lifting drive component is hinged to the active swinging component. The lifting drive component drives the active swinging component to swing while simultaneously driving the driven swinging component to swing through the connecting rod.

[0008] Optionally, the active swing component is triangular, with its three corners respectively hinged to the drive ends of the mounting frame, the lifting frame, and the lifting drive component. One end of the connecting rod is hinged to the part of the active swing component located between two adjacent corners. The driven swing component is triangular, with its three corners respectively hinged to the other end of the mounting frame, the lifting frame, and the connecting rod.

[0009] Optionally, the mounting frame is provided with a walking ramp, and the lifting frame is provided with a sliding engagement structure that engages with the walking ramp. When the engagement structure slides on the walking ramp, the lifting frame moves up and down and horizontally.

[0010] Optionally, the lifting platform also includes a carrier and a billet-combining drive. The carrier is movably disposed above the lifting frame, and the horizontal movement direction of the carrier is perpendicular to the horizontal movement direction of the lifting frame. The carrier is adapted to carry billets. The billet-combining drive is disposed on the lifting frame, and the carrier is translated by the billet-combining drive to combine billets.

[0011] Optionally, the lifting platform also includes a buffer component connected between the carrier and the lifting frame to slow down the movement speed of the carrier.

[0012] Optionally, the lifting platform also includes a carrier and a spring-loaded component. The carrier is movably disposed above the lifting frame, and the horizontal movement direction of the carrier is perpendicular to the horizontal movement direction of the lifting frame. The spring-loaded component is connected between the carrier and the lifting frame, and provides a restoring force for the carrier after it is rolled into blank.

[0013] Optionally, the lifting platform may also include a limiting component, which is mounted on the mounting frame to limit the lifting height of the lifting platform.

[0014] The present invention also provides an aerated concrete production line, comprising: a billet conveying line adapted to convey billets in a preset direction; and a billet-combining lifting platform disposed at the end of the billet conveying line, the billet-combining lifting platform comprising two lifting platforms disposed at intervals, the lifting platforms being the aforementioned lifting platforms.

[0015] This invention also provides a method for stacking billets using the aforementioned aerated concrete production line. The method includes the following steps: Step S10: Controlling the billet conveyor line to transport the billets on it toward the stacking lifting platform; Step S20: Detecting whether two stacks of billets arranged side-by-side and spaced apart have reached the two lifting platforms of the stacking lifting platform; Step S30: When the two stacks of billets arranged side-by-side and spaced apart have reached the two lifting platforms of the stacking lifting platform, controlling the billet conveyor line to stop, and then controlling the lifting frames of the two lifting platforms to rise while moving horizontally forward, so that the billets on each lifting platform... While the stack of blanks rises, it moves horizontally forward; Step S40: Detect whether the number of blanks on the two lifting platforms meets the requirement of one stack; Step S50: When the number of blanks on the two lifting platforms meets the requirement of one stack, merge the two stacks of blanks into one stack; when the number of blanks on the two lifting platforms does not meet the requirement of one stack, control the blank conveyor line to transport the last two stacks of blanks to the rear of the first two stacks of blanks, control the lifting frame to descend while moving horizontally backward, so that the first two stacks of blanks and the last two stacks of blanks fit together to form two new stacks of blanks; control the blank conveyor line to continue conveying forward, and then execute step S20.

[0016] Optionally, both lifting platforms include a carrier and a billet-combining drive. In step S50, the two billet-combining drive is controlled to drive the two carriers to move horizontally toward each other, merging the two stacks of billets into one stack. Alternatively, both lifting platforms include a carrier and a springback component. In step S50, the rotary clamping machine is controlled to clamp the two stacks of billets, merging the two stacks of billets into one stack. Alternatively, one of the two lifting platforms includes a carrier and a billet-combining drive. In step S50, the billet-combining drive is controlled to drive the carrier to move horizontally toward the other carrier, merging the two stacks of billets into one stack.

[0017] The present invention has the following advantages:

[0018] 1. The lifting drive unit drives the lifting frame to move horizontally while lifting. The lifting frame has both vertical and horizontal displacements during the lifting process, thus achieving a certain horizontal displacement of the billet while it is being lifted. This effectively separates the block being lifted from the other blocks, reducing the risk of the block tipping over during the lifting process due to misalignment or misalignment, and thus avoiding scratches.

[0019] 2. The lifting frame is raised and lowered and moved horizontally by the swinging of the swinging component. The structure is simple and easy to implement.

[0020] 3. A lifting drive unit drives the two sides of the lifting frame to lift synchronously through an active swinging component, a driven swinging component, and a connecting rod. This ensures that the lifting of the two sides of the lifting frame is synchronized and the movement is smooth. There is no problem of inconsistent speeds of the four cylinders. This effectively solves the problem of asynchronous lifting of the two sides of the lifting frame caused by the use of four cylinders to drive the lifting frame in the existing technology. Furthermore, by extending the driving arm through the connecting rod, the driving force is reduced. When space is sufficient, the required driving force can be greatly reduced, resulting in lower cost and higher reliability.

[0021] 4. During billet rolling, the load-bearing component is driven to move horizontally by the billet rolling drive component, and the billet and the load-bearing component do not move relative to each other, effectively avoiding the risk of the billet corner falling off.

[0022] 5. A buffer component is connected between the carrier and the lifting frame to slow down the movement speed of the carrier and prevent the billet from tipping over due to excessive lateral movement.

[0023] 6. Limiting components are installed on the mounting frame to limit the rising height of the lifting frame, which can ensure that the billet height is consistent. Attached Figure Description

[0046] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for 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. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0049] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] like Figures 1 to 5 As shown, the lifting platform in this embodiment includes: a mounting frame 10, a lifting frame 21, and a lifting drive component 22. The lifting frame 21 is movably mounted on the mounting frame 10 and is suitable for carrying the blank 80. The lifting drive component 22 is mounted on the lifting frame 21 and connected to the lifting frame 21. The lifting drive component 22 drives the lifting frame 21 to move horizontally while lifting it up and down.

[0051] Using the lifting platform of this embodiment, the lifting drive 22 drives the lifting frame 21 to move horizontally while lifting. The lifting frame 21 has both vertical and horizontal displacements while lifting, so that the billet has a certain horizontal displacement while lifting. This effectively separates the block being lifted from the other blocks, reduces the risk of the block tipping over during the lifting process due to misalignment or misalignment, and avoids scratches.

[0052] In this embodiment, the lifting platform also includes a lifting and translating mechanism 30. The lifting and translating mechanism 30 includes a swinging component, which is hinged to the drive ends of the mounting frame 10, the lifting frame 21, and the lifting drive component 22. The lifting drive component 22 drives the swinging component to swing, thereby causing the lifting frame 21 to move up and down and horizontally. This allows the billet to have a certain horizontal displacement while being lifted, effectively separating the block being lifted from the other blocks and reducing the risk of the billet tipping over during the lifting process due to misalignment or misalignment. The lifting and translating mechanism is simple in structure and easy to implement, driven by the swinging of the swinging component. It is understood that the specific structure of the lifting and translating mechanism is not limited to this; any lifting and translating mechanism that can achieve the lifting and translating of the lifting frame 21 is acceptable.

[0053] It is understood that, as an alternative implementation, the mounting frame 10 is provided with a walking ramp, and the lifting frame 21 is provided with a mating structure that slides with the walking ramp. When the mating structure slides on the walking ramp, the lifting frame 21 rises and falls and moves horizontally. At this time, the lifting drive component 22 is hinged to the mounting frame 10. Specifically, the mounting frame 10 includes a mounting frame and a fixing block. The fixing block is fixed on the mounting frame and has a walking ramp. The mating structure is either a mating ramp or a mating roller.

[0054] In the prior art, the lifting platform is driven by four cylinders. The four cylinders inevitably lead to inconsistent extension speeds, resulting in asynchronous lifting on both sides of the lifting frame. Furthermore, the lifting platform cannot perform billet merging; billet merging is achieved through a rotary clamping machine. To solve the problem of asynchronous lifting on both sides of the lifting frame, in this embodiment, the swinging component includes an active swinging component 31 and a driven swinging component 32. The active swinging component 31 and the driven swinging component 32 are connected to opposite sides of the lifting frame 21. There is one lifting drive component 22. The lifting and translating mechanism 30 also includes a connecting rod 33. One end of the connecting rod 33 is hinged to the active swinging component 31, and the other end is hinged to the driven swinging component 32. The driving end of the lifting drive component 22 is hinged to the active swinging component 31. The lifting drive component 22 drives the active swinging component 31 to swing while simultaneously driving it through the connecting rod 33. The driven swing member 32 swings, that is, a lifting drive member 22 drives the two sides of the lifting frame 21 to rise and fall synchronously through the active swing member 31, the driven swing member 32 and the connecting rod 33, so that the two sides of the lifting frame 21 rise and fall synchronously and move smoothly. There is no problem of inconsistent speed of four cylinders. This effectively solves the problem of asynchronous rising and falling of the two sides of the lifting frame caused by the use of four cylinders to drive the lifting frame of the existing lifting platform. Furthermore, by increasing the driving arm through the connecting rod 33, the driving force is reduced. When there is enough space, the required driving force can be greatly reduced, which naturally results in lower cost and higher reliability.

[0055] In this embodiment, the active swing member 31 is triangular, and its three corners are respectively hinged to the driving ends of the mounting frame 10, the lifting frame 21, and the lifting drive member 22. One end of the connecting rod is hinged to the portion of the active swing member 31 located between two adjacent corners. The driven swing member 32 is triangular, and its three corners are respectively hinged to the other ends of the mounting frame 10, the lifting frame 21, and the connecting rod 33. The structures of the active swing member 31 and the driven swing member 32 are simple and easy to implement.

[0056] Specifically, both the active swing member 31 and the driven swing member 32 include two opposing triangular plates and a connecting plate connecting the two triangular plates. Both the active swing member 31 and the driven swing member 32 are formed by assembling multiple plates, making them lightweight, easy to process and manufacture, and reducing costs. It can be understood that, as an alternative implementation, both the active swing member 31 and the driven swing member 32 are solid triangular blocks.

[0057] It should be noted that, as Figure 2 As shown, the active swing member 31 has a first hinge point 311, a second hinge point 312, a third hinge point 313, and a fourth hinge point 314. The first hinge point 311 is hinged to the mounting frame 10, the second hinge point 312 is hinged to the lifting frame 21, and the third hinge point 313 is hinged to the driving end of the lifting drive member 22. The driven swing member 32 has a fifth hinge point 321, a sixth hinge point 322, and a seventh hinge point 323. The fifth hinge point 321 is hinged to the mounting frame 10, and the sixth hinge point 322 is hinged to the lifting frame 21. One end of the connecting rod 33 is hinged to the fourth hinge point 314, and the other end is hinged to the seventh hinge point 323. The height position of the first hinge point 311 and... The fifth hinge point 321 is at the same height, meaning the first hinge point 311 and the fifth hinge point 321 must maintain the same height. The second hinge point 312 and the sixth hinge point 322 are at the same height, meaning the second hinge point 312 and the sixth hinge point 322 must maintain the same height. The fourth hinge point 314 and the seventh hinge point 323 are at the same height. The third hinge point 313 is located below the first hinge point 311. The lifting drive 22 drives the active swinging member 31 to swing around the first hinge point 311, while simultaneously driving the driven swinging member 32 to swing around the fifth hinge point 321 via the connecting rod 33, thereby driving the lifting frame 21 to move horizontally while lifting. The lifting drive 22 drives the lifting frame 21 to move horizontally while lifting, through the active swinging member 31, the driven swinging member 32, and the connecting rod 33. The lifting frame 21 has both vertical and horizontal displacements during lifting, which can reduce the risk of billet tipping over during the lifting process due to billet misalignment or asymmetry.

[0058] Specifically, the lifting drive component 22 can be a lifting hydraulic cylinder, a lifting pneumatic cylinder, or a lifting electric actuator, etc. It should be noted that... Figure 2 F1 in the figure refers to the force exerted by the lifting drive component 22 on the active swing component 31. The first hinge point 311, the fifth hinge point 321 and the second hinge point 312, the sixth hinge point 322 are not necessarily at the same height. When the heights of the first hinge point 311, the fifth hinge point 321 and the second hinge point 312, the sixth hinge point 322 are inconsistent, and the different lifting heights and lateral movement distances of the lifting frame 21 are adjusted by changing the stroke of the cylinder or the hydraulic cylinder.

[0059] In this embodiment, the fourth hinge point 314 is located below the first hinge point 311 and above the third hinge point 313, which can prevent interference between the lifting drive component 22 and the connecting rod 33. It can be understood that, provided the lifting drive component 22 and the connecting rod 33 do not interfere, the fourth hinge point is located below the third hinge point.

[0060] Specifically, the first hinge point 311 of the active swing member 31 is mounted on the mounting frame 10 via the first fixed rotating shaft 34; the second hinge point 312 of the active swing member 31 is mounted on the lifting frame 21 via the first driven shaft 35; the third hinge point 313 of the active swing member 31 is connected to the driving end of the lifting drive member 22 via the active shaft 36; the fifth hinge point 321 of the driven swing member 32 is mounted on the mounting frame 10 via the second fixed rotating shaft 37; and the sixth hinge point 322 of the driven swing member 32 is mounted on the lifting frame 21 via the second driven shaft 38. When the active swing member 31 swings, it swings around the axis of the first fixed rotating shaft 34; when the second driven swing member 32 swings, it swings around the axis of the second fixed rotating shaft 37. The axes of the first fixed rotating shaft 34 and the second fixed rotating shaft 37 are at the same height, and the axes of the first driven shaft 35 and the second driven shaft 38 are at the same height.

[0061] Preferably, such as Figures 2 to 4 As shown, the mounting frame 10 is equipped with two first bearing seats 23 and two second bearing seats 24, and the lifting frame 21 is equipped with two third bearing seats 25 and two fourth bearing seats 26. The two ends of the first fixed rotating shaft 34 are installed in the two first bearing seats 23, the two ends of the second fixed rotating shaft 37 are installed in the two second bearing seats 24, the two ends of the first driven shaft 35 are installed in the two third bearing seats 25, and the two ends of the second driven shaft 38 are installed in the two fourth bearing seats 26.

[0062] In existing technology, the lifting frame of the lifting platform only performs lifting functions. During billet stacking, a rotating clamping machine is used to achieve the stacking. Relative friction exists between the billet and the lifting frame, increasing the risk of the billet chipping. To avoid this risk, in this embodiment, as follows... Figure 1As shown, the lifting platform also includes a support member 41 and a billet-jointing drive member 42. The support member 41 is movably disposed above the lifting frame 21, and the horizontal movement direction of the support member 41 is perpendicular to the horizontal movement direction of the lifting frame 21. The support member 41 is adapted to support the billet 80. The billet-jointing drive member 42 is disposed on the lifting frame 21 and drives the support member 41 to translate, thereby joining the billets. During billet joining, the support member 41 is driven to move horizontally by the billet-jointing drive member 42, and the billet 80 and the support member 41 do not move relative to each other, effectively avoiding the risk of the billet corners falling off. Specifically, the billet-jointing drive member 42 can be a billet-jointing hydraulic cylinder, a billet-jointing pneumatic cylinder, or a billet-jointing electric pusher cylinder, etc., and the billet-jointing drive member 42 has a telescopic function. Specifically, the support member 41 can be a support plate or a support frame, etc.

[0063] In this embodiment, as Figure 1 and Figure 3 As shown, the lifting platform also includes a buffer component 50, which is connected between the carrier 41 and the lifting frame 21 to slow down the moving speed of the carrier 41 and prevent the billet from tipping over due to excessive lateral movement. Specifically, the buffer component 50 is a hydraulic buffer or an elastic element, etc.

[0064] In this embodiment, the lifting platform further includes a guide mechanism 44, which is disposed between the carrier 41 and the lifting frame 21 to guide the movement of the carrier 41, thereby improving the blanking accuracy of the carrier 41. Specifically, the guide mechanism 44 includes a guide rail 441 and a slider that slides with the guide rail 441. The guide rail 441 is fixed on the lifting frame 21, and the slider is fixed on the carrier 41. The slider is slidably disposed on the guide rail 441, and moves on the guide rail 441 when the carrier 41 moves.

[0065] In this embodiment, the lifting platform also includes a limiting component, which is mounted on the mounting frame 10 to limit the rising height of the lifting frame 21, ensuring consistent blank height. Specifically, the limiting component is adapted to limit the swing angle of the active swing member 31. The limiting component includes a limiting bolt, which is movably mounted on the mounting frame 10 and adapted to cooperate with the active swing member 31. By adjusting the position of the limiting bolt on the mounting frame 10, the swing angle of the active swing member 31 can be adjusted, thereby adjusting the rising height of the lifting frame 21. The limiting component also includes two limiting nuts. The mounting frame 10 is provided with a mounting plate, and the two limiting nuts are located on both sides of the mounting plate and threadedly connected to the limiting bolt. The position of the limiting bolt can be adjusted by adjusting the two limiting nuts, making adjustment simple. It can be understood that the limiting component can also limit the swing angle of the driven swing member 32.

[0066] In this embodiment, as Figure 1As shown, the mounting frame 10 includes a mounting frame 11 and multiple support legs 12. The mounting frame 11 is connected to the top of the multiple support legs 12. Each support leg 12 is provided with a height adjustment component 13. The height of the mounting frame 11 can be adjusted by the height adjustment component 13, thereby accommodating the height of different conveyor lines.

[0067] Specifically, the height adjustment component 13 includes an adjusting bolt and two adjusting nuts. The adjusting bolt is mounted on the support leg via the two adjusting nuts. The position of the adjusting bolt is adjusted by adjusting the two adjusting nuts, thereby adjusting the height of the mounting frame. The mounting frame 10 also includes a base plate 14, on which each height adjustment component 13 is mounted. The base plate 14 is fixed to the ground by bolts.

[0068] Example 1

[0069] The billet lifting platform in this embodiment includes two lifting platforms spaced apart. The two lifting platforms are the same as those described above, and the two lifting platforms have the same structure.

[0070] Example 2

[0071] like Figure 17 As shown, the difference between the billet lifting platform in Embodiment 2 and Embodiment 1 lies in whether or not a billet driving component 42 is provided. In Embodiment 2, the billet driving component 42 is omitted from both lifting platforms. Each lifting platform also includes a spring-loaded component 43. The spring-loaded component 43 is connected between the carrier component 41 and the lifting frame 21. The spring-loaded component 43 provides a reset force for the carrier component 41 after billet loading. At this time, billet loading is achieved by rotating the billet clamping machine. The billet and the carrier component 41 move along the guide rail 441 under the clamping force of the rotating billet clamping machine. At this time, there is no relative movement between the billet and the carrier component 41. When the billet is removed, the frictional resistance decreases, and the spring-loaded component 43 sends the carrier component 41 back to the origin.

[0072] Specifically, the rebound component 43 is a spring, an elastic column, or an elastic sleeve, etc.

[0073] It should be noted that, Figure 17 F2 in this context refers to the clamping force of the rotary blank clamping machine.

[0074] Example 3

[0075] like Figure 18As shown, the difference between the billet-combining lifting platform in Embodiment 3 and Embodiment 2 lies in the number of springback components 43. In Embodiment 3, the two lifting platforms are the first lifting platform and the second lifting platform. The first lifting platform is equipped with a billet-combining drive component 42, which drives the carrier component 41 to move, thereby realizing the combination of billets. When the billet is removed, the carrier component 41 is sent back to the origin by the billet-combining drive component 42. The second lifting platform is not equipped with a billet-combining drive component 42, springback component 43 and guide mechanism 44. The carrier component 41 and the lifting frame 21 of the second lifting platform are combined into a lifting carrier component.

[0076] It should be noted that, Figure 18 F3 in the figure refers to the force applied to the billet by the billet driving component 42.

[0077] This invention also provides a billet conveying line, comprising: a billet conveying line 71 and a billet lifting platform as described in Embodiments 1, 2, or 3 above. The billet conveying line 71 is adapted to convey billets along a preset direction. The billet lifting platform is located at the tail end of the billet conveying line 71. Compared with the prior art, the billet lifting platform can solve the problems of asynchronous lifting, billet corner loss, and billet tilting or tipping after being lifted, and can realize the stacking of whole billets and surplus billets. Embodiments 1, 2, and 3 can all ensure that there is no relative movement between the billet and the carrier 41, thus avoiding the risk of billet corner loss.

[0078] The present invention also provides an aerated concrete production line, which includes the above-mentioned billet conveying line.

[0079] In this embodiment, as Figure 19 As shown, the aerated concrete production line also includes a single-mold clamping machine 73, a rotary clamping machine 74, and a block conveying line 75. The head of the billet conveying line 71 extends into the single-mold clamping machine 73, which clamps a single-mold billet onto the billet conveying line 71 of the billet-combining conveying line. The rotary clamping machine clamps a stack of billets after they have been combined onto the block conveying line 75.

[0080] The present invention also provides a method for batching aerated concrete blocks using the above-mentioned aerated concrete production line. The method includes the following steps:

[0081] Step S10: Control the billet conveying line 71 to convey the billets on it toward the billet lifting platform 72;

[0082] Step S20: Detect whether the two stacks of billets arranged side by side and spaced apart have reached the two lifting platforms of the billet stacking lifting platform 72.

[0083] Step S30: When two stacks of billets placed side by side and spaced apart arrive at the two lifting platforms of the billet lifting platform 72, the billet conveying line 71 is stopped. Then, the lifting frames 21 of the two lifting platforms are raised and moved forward horizontally at the same time, so that a stack of billets on each lifting platform is raised and moved forward horizontally at the same time. This effectively separates the blocks being lifted from the blocks behind them, reduces the risk of blocks tipping over during the lifting process due to misalignment or misalignment, and avoids scratches.

[0084] It should be noted that the billet conveying line 71 is used to convey several stacks of billets arranged side by side and spaced apart. The first detection component is used to detect whether the billet has reached the lifting platform. The detection component is a camera or proximity switch, etc.

[0085] In this embodiment, after step S30, the billet rolling method further includes:

[0086] Step S40: Check whether the number of blanks on the two lifting platforms meets the requirement of one stack;

[0087] Step S50: When the number of blanks on the two lifting platforms meets the requirement of one stack, the two stacks of blanks are merged into one stack to achieve blank merging, which facilitates material unloading.

[0088] It should be noted that when a stack of blanks is exactly one mold blank, two mold blanks arranged side by side and spaced apart can be combined into one stack.

[0089] It should be noted that the second detection component, such as a camera or proximity switch, is used to check whether the number of billets on the two lifting platforms meets the requirement of forming a stack. This detection can also be done manually.

[0090] In this embodiment, when a stack of blanks is insufficient to form a single mold blank, the blank-combining method further includes the following after step S40:

[0091] When the number of billets on the two lifting platforms is insufficient to form a stack, the billet conveyor line 71 is controlled to transport the latter two stacks of billets to the rear of the former two stacks. Simultaneously, the lifting frame 21 is controlled to descend and move horizontally backward, causing the former two stacks of billets and the latter two stacks to fit together to form two new stacks of billets. The billet conveyor line 71 is then controlled to continue conveying forward, and step S20 is executed. This billet merging method can merge surplus billets, making it more widely applicable.

[0092] When using the billet-combining lifting platform of Embodiment 1 above, that is, when both lifting platforms include a bearing member 41 and a billet-combining driving member 42, in step S50, the two billet-combining driving members 42 are controlled to drive the two bearing members 41 to move horizontally towards each other, merging the two stacks of billets into one stack. After billet combination, one stack of billets is clamped away by a rotary clamping machine and then removed from the production line; after the billets are removed, the two billet-combining driving members 42 are controlled to drive the two bearing members 41 to move horizontally away from each other, so that the two bearing members 41 are returned to their original positions.

[0093] When using the billet-combining lifting platform of Embodiment 2 above, when both lifting platforms include a carrier 41 and a springback component 43, in step S50, the rotary billet clamping machine is controlled to clamp the two stacks of billets, merging the two stacks of billets into one stack. The billet-combining is achieved through the rotary billet clamping machine. The billet and the carrier 41 move along the guide rail 441 under the clamping force of the rotary billet clamping machine. At this time, there is no relative movement between the billet and the carrier 41. When the billet is removed, the frictional resistance decreases, and the springback component 43 sends the carrier 41 back to its origin.

[0094] When using the billet-combining lifting platform of Embodiment 3, one of the two lifting platforms includes a carrier 41 and a billet-combining driving component 42. In step S50, the billet-combining driving component 42 is controlled to drive the carrier 41 to move horizontally toward the other carrier 41, merging the two stacks of billets into one stack. After the billets are taken away by the rotating billet clamping machine, the billet-combining driving component 42 is controlled to drive the carrier 41 to move horizontally away from the other carrier 41, so that the carrier 41 is returned to its original position.

[0095] When the entire billet comes off the production line, the following steps are combined Figures 6 to 10 The method for removing the billet from the production line is explained below:

[0096] 1. The billet conveying line 71 of the billet conveying line delivers the two mold billets to the designated position. At this time, the bearing component 41 of the billet lifting platform 72 is in the retracted state.

[0097] 2. After the two blanks reach the designated position, the blank lifting platform works, and the lifting cylinder lifts the blank by 80 degrees.

[0098] 3. The billet merging cylinder combines the two blanks into one stack;

[0099] 4. The rotating clamping machine picks up the billet at 80°.

[0100] 5. The billet cylinder retracts, followed by the lifting cylinder, and the billet conveyor line moves to continue feeding the subsequent billets 80 forward. This cycle continues until all billets are off the line.

[0101] When the remaining blanks are removed from the production line, the following steps are combined: Figures 11 to 16 The method for removing the billet from the production line is explained below:

[0102] 1. The first remaining billet reaches the designated position via billet conveyor line 71;

[0103] 2. The billet lifting platform raises the first remaining billet and ensures that the first remaining billet is placed at the end of the billet lifting platform;

[0104] 3. The second excess brick reaches the rear of the first excess blank through the blank conveyor line 71. Note that there should be a gap between the second excess brick and the first excess blank at this time to avoid collision between the front and rear excess blanks.

[0105] 4. The load-bearing component 41 and the lifting frame 21 of the billet lifting platform descend, and the first and second surplus billets come into contact;

[0106] 5. The billet conveyor line 71 carries the first and second surplus billets forward. When a stack is completed, the lifting and billet merging actions are performed, and the billets are taken away by the rotating billet clamping machine; if a stack is not completed, the previous actions are repeated until a stack is completed.

[0107] It should be noted that the blank is a block or brick.

[0108] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0109] 1. The billet-combining lifting platform includes two lifting platforms. Each lifting platform includes a mounting frame 10, a bearing component 41, a lifting frame 21, a guide mechanism 44, a billet-combining drive component, a lifting and translating mechanism, and a lifting drive component. The billet-combining lifting platform is configured on the billet-combining conveyor line. The billet-combining drive component is connected to the bearing component 41 to realize the lateral movement of the bearing component and the billet body. This allows the billet-combining lifting platform to realize the block lifting and billet-combining action, as well as the lifting and billet-combining function of whole bricks and excess bricks, which speeds up the finished product output cycle. There is no relative movement between the block and the support surface of the bearing component 41, which reduces the situation of block friction and corner chipping, making the block less prone to damage.

[0110] 2. Lifting and lateral movement are achieved through a single lifting drive component. The structure is simple, and the lifting on both sides of the lifting frame 21 is synchronized and the movement is smooth. There is no problem of inconsistent speeds among the four cylinders.

[0111] 3. The lifting and translating mechanism includes an active swing component 31, a driven swing component 32, and a connecting rod 33. The active swing component 31 is equipped with an active shaft 36, a first fixed rotating shaft 34, and a first driven shaft 35. The driven swing component 32 is equipped with a second fixed rotating shaft 37 and a second driven shaft 38. When the lifting platform is running, the lifting drive component applies a force to the active shaft 36, causing the first driven shaft 35 to rotate around the first fixed rotating shaft 34, thus achieving vertical and horizontal movement of the first driven shaft 35, thereby realizing the movement of the lifting frame 21 and the load-bearing component 41. The lifting mechanism also has a certain horizontal displacement, which allows the billet to have a certain horizontal displacement while it is being lifted. This effectively separates the block being lifted from the other blocks, reducing the risk of the block tipping over during the lifting process due to misalignment, and thus avoiding scratches. Power is transmitted to the driven swing member 32 through the connecting rod 33, realizing the synchronous movement of the active swing member 31 and the driven swing member 32. The connecting rod 33 connects the active swing member 31 and the driven swing member 32. The driving force arm is greater than the load force arm, which can reduce the required driving force.

[0112] 4. The brick-combining lifting platform can realize the function of combining excess bricks, which can be applied to the logic of brick-combining and unloading without pallets, resulting in a faster cycle time.

[0113] 5. The billet-combining drive is eliminated, and billet-combining is achieved by a rotary clamping machine. The blocks and the support plate 41 move along the guide rail 441 under the action of clamping force. At this time, there is no relative movement between the blocks and the support plate. A springback component is set up. When the billet is removed, the frictional resistance decreases, and the springback component sends the support plate 41 back to the origin.

[0114] 6. One lifting platform has only lifting function, while the other lifting platform has a billet-combining drive and a lifting drive. That is, the other lifting platform can realize lifting and billet-combining functions. When the billet is taken away, the billet-combining drive will send the carrier 41 back to the origin.

[0115] 7. Limiting components are installed on the mounting frame 10 to adjust the extension distance of the lifting cylinder and ensure that the billet height is consistent.

[0116] 8. Adjusting bolts are provided on the legs of the mounting frame 10 to facilitate adjustment of the height of the bearing plate when the lifting cylinder completes its retraction. The legs adopt an assembled structure, which is compatible with different conveyor line heights.

[0117] 9. A guide mechanism 44 is provided between the carrier 41 and the lifting frame 21. The guide mechanism 44 includes a guide rail 441 and a slider. The guide rail 441 is provided on the lifting frame 21, and the slider is provided on the carrier 41. The lateral movement of the carrier 41 can be guided by the cooperation of the slider and the guide rail 441.

[0118] 10. A buffer component is installed between the load-bearing component 41 and the lifting frame 21 to prevent the blocks from tipping over due to excessive lateral movement speed.

[0119] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
