Description

Technical Field

[0001] This application relates to the field of concrete component production technology, and more specifically to a cover plate production system and its working method. Background Technology

[0002] Currently, in the fields of infrastructure construction such as buildings, municipal works, and water conservancy, precast concrete covers are widely used for covering and protecting facilities such as cable trenches, drainage ditches, and inspection wells.

[0003] However, the current production of precast concrete cover slabs mostly adopts a single-mold, one-by-one molding method, which is inefficient. Each cover slab must go through a complete cycle of molding, pouring, static curing, demolding, transportation, and packaging. The production rhythm of each cover slab is independent, making it difficult to form a continuous and efficient assembly line operation. The output per unit time is limited, and the labor and space requirements are large. Secondly, after demolding, the molded cover slabs are usually in a scattered state. Subsequent stacking, transportation, and packaging processes rely heavily on manual handling and repeated handling and arrangement of individual slabs. This single-piece flow method is not only labor-intensive and has a high transportation frequency, but also makes the cover slabs prone to edge collisions, surface wear, and other damage during repeated disordered handling and stacking, affecting the appearance quality and yield of the product. Summary of the Invention

[0004] The purpose of this application is to provide a cover plate production system and its working method to improve the quality and efficiency of cover plate output.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a cover plate production system is provided, including: a pouring and compacting mechanism, a cover plate forming mold, and a transfer mechanism; the cover plate forming mold includes a base plate and multiple side plates, the multiple side plates are detachably connected to the base plate and are disposed around the base plate, the base plate and the multiple side plates enclose to form a mold cavity, the mold cavity is provided with multiple partitions, the multiple partitions are parallel to each other and spaced apart, so as to divide the mold cavity into multiple parallel and upward-facing cover plate forming cavities; wherein, the pouring and compacting mechanism is used to discharge and vibrate the cover plate forming mold, and when the cover plate forming mold reaches the demolding strength, the cover plate in the cover plate forming mold is demolded, the multiple cover plates corresponding to the demolded cover plates in the multiple cover plate forming cavities are kept parallel to each other according to the arrangement direction of the cover plate forming cavities, and the multiple cover plates are transferred to the packaging station as a single cover plate group by the transfer mechanism.

[0006] As a preferred embodiment, the system further includes a conveying mechanism, which is provided with a pouring station, a demolding station, and a static stopping station. The pouring mechanism is configured corresponding to the pouring station to discharge and vibrate the cover plate forming mold located at the pouring station. The conveying mechanism transports the vibrated cover plate forming mold to the static stopping station for curing, and after the cover plate forming mold reaches the demolding strength, it transports the cover plate forming mold to the demolding station for demolding.

[0007] As a preferred embodiment, the transfer mechanism is located between the stationary stop station and the demolding station, and the working range of the transfer mechanism covers both the stationary stop station and the demolding station.

[0008] Further preferably, the transfer mechanism includes a first transfer mechanism and a second transfer mechanism. The first transfer mechanism has a first rotation radius, and the circular working area formed by the first rotation radius covers the stationary stop. The second transfer mechanism has a second rotation radius, and the circular working area formed by the second rotation radius covers the demolding station. The circular working area of ​​the first transfer mechanism is tangent to the circular working area of ​​the second transfer mechanism.

[0009] Further preferably, the side plate has upper and lower slots arranged at intervals along the vertical direction, and the side of the partition has corresponding upper and lower protrusions. The upper protrusion is inserted into the upper slot, and the lower protrusion is inserted into the lower slot to fix the partition in the mold cavity. The lower edge of the lower slot is higher than the upper surface of the bottom plate to form a closed section on the side plate between the lower slot and the bottom plate, and the lower edge of the partition overlaps with the closed section.

[0010] Further preferably, the multiple side plates include a first side plate and a second side plate arranged adjacent to each other, the first side plate and the second side plate being arranged perpendicular to each other, the first side plate having a first slot, the second side plate having a second slot, the first slot and the second slot being corresponding in position and connected; the cover plate forming mold also includes a locking rod, the locking rod simultaneously passing through the first slot and the second slot to simultaneously prevent the first side plate and the second side plate from detaching outward.

[0011] As another preferred embodiment, the cover plate production system further includes a demolding bracket, which includes an insertion part and a support part. The support part is fixedly connected to the insertion part. The insertion part is used to extend under the bottom plate for positioning. The support part extends to one side of the cover plate forming mold. During demolding, the cover plate in the cover plate forming cavity is bent to an inclined state and abuts against the support part, so that the cover plate and the partition plate are separated from each other.

[0012] As another preferred embodiment, the tamping mechanism includes a vibrating table, which is used to support the cover plate forming mold and apply vibration to the cover plate forming mold to complete the tamping of the cover plate forming mold.

[0013] Furthermore, this application also provides a method for operating a cover plate production system. This method is applicable to any of the cover plate production systems described above. The method includes: Step S10: Connecting multiple side plates of the cover plate forming mold to the perimeter of the base plate, so that the base plate, the multiple side plates, and multiple partitions located on the base plate together form multiple parallel-arranged cover plate forming cavities with upward-facing openings; feeding material into the multiple cover plate forming cavities; and vibrating the entire cover plate forming mold to form multiple cover plates in parallel within the same cover plate forming mold; Step S20: Maintaining the connection between the multiple side plates and the base plate, transferring the vibrated entire cover plate forming mold to... Step S30: After the multiple cover plates reach the preset demolding strength, the entire cover plate forming mold is transferred to the demolding station to complete the demolding of the cover plates; Step S40: The cover plates located at both ends of the multiple cover plates in the arrangement direction are clamped, and the distance between the two ends of the cover plate group in the arrangement direction is reduced to eliminate the gap between adjacent cover plates after demolding, so that the adjacent cover plates are in contact with each other; In the state where the multiple cover plates are in contact with each other, the multiple cover plates are transferred as a whole to the packaging station; Step S50: While maintaining the state where the multiple cover plates are in contact with each other and the original arrangement order, the multiple cover plates are packaged as a whole.

[0014] Preferably, step S30 further includes step S31: demolding the cover plate forming mold with the assistance of a demolding bracket, the demolding bracket including an insertion part and a support part connected to each other, inserting the insertion part under the bottom plate of the cover plate forming mold, so that the support part of the demolding bracket is located on one side of the inclined direction of the plurality of cover plates; step S32: demolding the cover plates sequentially along the arrangement direction of the plurality of cover plates, so that the demolded cover plates are inclined against the support part, at which time the cover plates are separated from the corresponding partitions; step S33: after all the partitions are removed, rotating the plurality of cover plates against the demolding bracket from the inclined state to the vertical state, forming a cover plate assembly that can be clamped and transported in a single operation.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: Multiple parallel cover plates are formed in one go using a single mold. During the subsequent static curing, demolding, and transfer and packaging processes, the original parallel arrangement and relative position order of these cover plates are maintained. This minimizes the risk of collisions and damage between the multiple cover plates, resulting in high-quality cover plates. Finally, a transfer mechanism transfers and packages the multiple cover plates as a whole cover plate assembly, enabling efficient and mass production of concrete cover plates.

Detailed Implementation

[0029] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0032] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0033] In a preferred embodiment, see Figures 1 to 12 This application provides a cover plate production system 1, and see details below. Figure 1 and Figure 2The cover plate production system 1 includes: a pouring mechanism 10, a cover plate forming mold 20, and a transfer mechanism 50; the cover plate forming mold 20 includes a base plate 21 and multiple side plates 22, the multiple side plates 22 are detachably connected to the base plate 21 and are arranged around the base plate 21, the base plate 21 and the multiple side plates 22 enclose to form a shape such that... Figure 5 The mold cavity 23 shown contains multiple partitions 25. These partitions 25 are parallel to each other and spaced apart, dividing the mold cavity 23 into multiple parallel, upward-facing cover plate forming cavities 24. Figure 3 As shown; wherein, the pouring and tamping mechanism 10 is used to discharge and vibrate the cover plate forming mold 20. When the cover plate forming mold 20 reaches the demolding strength, the cover plate 2 in the cover plate forming mold 20 is demolded. The multiple cover plates 2 that are demolded from the multiple cover plate forming cavities 24 are arranged in parallel with each other according to the arrangement direction of the cover plate forming cavities 24. The multiple cover plates 2 are transferred to the packaging station as a single cover plate 2 group by the transfer mechanism 50.

[0034] Specifically, see Figure 3 The cover plate forming mold 20 is a key device for realizing the parallel forming of multiple cover plates 2. The cover plate forming mold 20 includes a base plate 21 and four side plates 22. The four side plates 22 are detachably connected to the base plate 21 and are vertically arranged around the base plate 21. The base plate 21 and the four side plates 22 together form a cuboid cavity 23 with an opening at the top. In order to form multiple independent cover plates 2 in a single cavity 23 at the same time, multiple partitions 25 are provided in the cavity 23. The multiple partitions 25 are all thin plate structures. The multiple partitions 25 are parallel to each other and equally spaced along the length of the cavity 23, thereby dividing the overall cavity 23 into multiple parallel and upward-facing independent cover plate forming cavities 24. The thickness and height of each cover plate forming cavity 24 correspond to the thickness and height of the cover plate 2 to be produced, and its width is determined by the spacing between adjacent partitions 25. After pouring concrete material into the mold at one time and vibrating it, multiple cover plates 2 of the same specifications can be formed in parallel in the same mold. Each cover plate 2 is separated by partitions 25 and maintains a parallel arrangement in space.

[0035] Among them, see Figure 7To further improve the parallelism and spacing consistency of the partitions 25 in the middle section of the mold cavity 23 along its length, this embodiment also adds a positioning plate 80 above the partitions 25. The positioning plate 80 is a rigid, elongated plate whose length spans all the parallel-arranged cover plate forming cavities 24 and is arranged perpendicular to the surface of each partition 25. The lower edge of the positioning plate 80 has multiple positioning slots, the positions of which correspond one-to-one with the upper edges of each partition 25. When each partition 25 is inserted into the mold cavity 23, the positioning plate 80 straddles the partitions 25 from above, so that the upper edge of each partition 25 fits precisely into the corresponding positioning slot. At this time, the positioning plate 80, using its continuous rigidity, forcibly locks the distance between the upper ends of each partition 25 at a preset equal spacing. Any tendency of a partition 25 to become partially skewed due to concrete compression or other external forces will be fixed by the positioning slots. The plate 80 and adjacent partitions 25 work together to constrain and correct the structure. By setting the positioning plate 80, the upper ends of all partitions 25 can be rigidly interlocked in the horizontal direction at one time. Structurally, this ensures that the multiple cover plate forming cavities 24 have a highly consistent cavity width throughout the entire length range. This avoids the problem of the upper end of the partition 25 tilting to one side or developing a flared shape. As a result, it further improves the uniformity of the thickness of the forming cover plate 2 and the neatness of the arrangement of the group of cover plates 2. This provides a more accurate dimensional guarantee for the tight fit and overall transportation of multiple cover plates 2 after demolding.

[0036] Therefore, the integrated multi-cavity mold design provided in this application greatly increases the number of molds produced in a single batch compared to the production method of one mold and one cover plate 2 in related technologies. It also provides a structural basis for maintaining the arrangement order of the cover plates 2 and realizing group transfer. At the same time, it establishes a parallel arrangement order between multiple cover plates 2 from the source of the cover plate 2 molding structure, avoiding the disorderly stacking and rearrangement of the cover plates 2 in the future, and significantly improving production efficiency and space utilization.

[0037] Meanwhile, this application document achieves the one-time parallel molding of multiple cover plates 2 by setting multiple parallel-arranged cover plate forming cavities 24 in the same mold. After the cover plates 2 are demolded, the multiple cover plates 2 still maintain their original parallel arrangement. The transfer mechanism 50 can clamp and squeeze these multiple cover plates 2 from both ends of the arrangement direction at one time, so that they are tightly attached to each other and become a close whole. Thus, they are transferred as an indivisible group of cover plates 2 to the packaging station. This method integrates the scattered operations of multiple single-piece clamping and transfer into a single group handling, which greatly facilitates the overall transfer, significantly shortens the transfer cycle, multiplies the production efficiency, and avoids the collision damage that is easy to occur between cover plates 2 during the transfer of single cover plates 2.

[0038] Preferably, to facilitate the rapid assembly and disassembly of the side plates 22, the connection between the side plates 22 and the base plate 21 is a detachable connection, such as by bolt fastening, wedge locking, or snap fastener connection. During the production preparation stage, the four side plates 22 are accurately positioned around the base plate 21 and locked in place. Then, according to the required number of cover plates 2, the corresponding number of partitions 25 are inserted into the mold cavity 23, thus quickly completing the mold assembly. After the cover plates 2 have solidified, simply disconnect the connection between the side plates 22 and the base plate 21 to separate the side plates 22 from the solidified cover plate 2 assembly, preparing for demolding and removal of the cover plates 2.

[0039] Also see Figures 4 to 6 To further enhance the connection strength and overall rigidity between the side plates 22 and prevent them from expanding outwards under significant lateral pressure from concrete, this embodiment also optimizes the locking structure of adjacent side plates 22. Specifically, the four side plates 22 include two first side plates 27 and two second side plates 28. The length of the first side plates 27 is shorter than that of the second side plates 28. The first side plates 27 and the second side plates 28 are arranged adjacent to each other and perpendicular to each other, forming a right-angle corner of the mold. A first slot 271 is provided near the edge of the first side plate 27; a second slot 281 is provided near the corresponding edge of the second side plate 28. Both the first slot 271 and the second slot 281 are notches opened downwards from the top edge of the side plates 22. When the first side plates 27 and the second side plates 28 are assembled on the base plate 21, the positions of the first slot 271 and the second slot 281 are aligned and connected to each other, forming an integral locking groove. The cover plate forming mold 20 is also equipped with a locking rod 29. The locking rod 29 can be made of square steel, round steel, or other rods with sufficient bending stiffness. In use, the locking rod 29 is simultaneously inserted from top to bottom into the interconnected first slot 271 and second slot 281. The rod body of the locking rod 29 is simultaneously engaged in the slots of the first side plate 27 and the second side plate 28. At this time, the locking rod 29 effectively locks the first side plate 27 and the second side plate 28. When the first side plate 27 is subjected to... When the outward pushing force attempts to disengage, the edge of the slot will press against the locking rod 29, while the locking rod 29 is simultaneously constrained by the slot of the second side plate 28. Since the second side plate 28 is in the vertical direction, its force direction is different and its displacement trend is also different, thus forming a mutually restrictive mechanical lock, which effectively prevents the first side plate 27 and the second side plate 28 from disengaging outward at the same time. Through the setting of the locking rod 29, the side plate 22 is provided with strong resistance to lateral pressure, thus avoiding the occurrence of mold bulging.

[0040] Based on this, to further improve the reliability and uniformity of locking, multiple first slots 271 are spaced apart along the length of the first side plate 27, and multiple second slots 281 of the same number are correspondingly opened on the second side plate 28. The number of locking rods 29 is also multiple, and the multiple locking rods 29 are inserted into the multiple first slots 271 and second slots 281 in a one-to-one correspondence. In this way, the locking force originally concentrated at a single locking point is distributed to multiple locking points along the length of the side plate 22 through multi-point locking, so that the connection force between the first side plate 27 and the second side plate 28 is more evenly distributed. This is especially suitable for molds with large length dimensions, and can effectively avoid the slight bending deformation that occurs in the middle section of the long side plate 22 due to lack of constraint. The distributed multi-point locking significantly enhances the connection rigidity and bending resistance of the long side plate 22, ensuring the accuracy and stability of the shape of the entire mold cavity 23.

[0041] As a further reinforcement measure, nuts 291 can be provided at both ends of the locking rod 29. After the locking rod 29 is inserted into the first slot 271 and the second slot 281, the nuts 291 are screwed in from both ends of the locking rod 29 and tightened until the end face of the nut 291 is tightly against the outer end face of the slot of the first side plate 27 and the second side plate 28. At this time, a strong frictional force is generated between the nut 291 and the outer wall of the side plate 22, which not only provides axial preload to pull the two side plates 22 tightly together, but also forms a physical barrier in the structure. This means that when the first side plate 27 and the second side plate 28 are subjected to outward thrust, they need to overcome the huge frictional force of the end face of the nut 291 or shear the locking rod 29, which further restricts the disengagement displacement of the side plate 22.

[0042] Furthermore, to prevent the locking rod 29 from accidentally jumping upwards and falling off under the influence of equipment vibration or external force, the first slot 271 extends downwards from the top edge of the first side plate 27 and inclined towards the inside of the mold cavity 23, and the second slot 281 extends downwards from the top edge of the second side plate 28 and inclined towards the inside of the mold cavity 23. This makes both the first slot 271 and the second slot 281 open obliquely upwards, further improving the connection reliability of the locking rod 29 and reducing the risk of the locking rod 29 loosening due to vibration.

[0043] Furthermore, multiple reinforcing ribs 30 are provided on the outer surfaces of both the first side plate 27 and the second side plate 28 to enhance their rigidity and strength. Specifically, the reinforcing ribs 30 extend vertically and are integrally formed or firmly welded to the surfaces of the first side plate 27 and the second side plate 28. The first slot 271 is formed on the reinforcing rib 30 of the first side plate 27, integrating the functional locking slot with the structural reinforcing rib 30 into a single design. This achieves both connection and overall rigidity of the mold, ensuring that the mold maintains dimensional accuracy and structural integrity even under repeated heavy loads and disassembly / reassembly.

[0044] Further, see Figure 3 and Figure 5 On the inner walls of the two opposing side plates 22, specifically, in this embodiment, on the two opposing second side plates 28, upper slots 221 and lower slots 222 are provided at intervals along the vertical direction. The upper slot 221 is located in the upper region of the inner wall of the second side plate 28, and the lower slot 222 is located in the lower region of the inner wall of the side plate 22. Both are on the same straight line in the vertical direction. Correspondingly, on the left and right sides of each partition plate 25, outwardly protruding upper protrusions 251 and lower protrusions 252 are provided. The position and shape of the upper protrusions 251 match the upper slots 221 on the side plate 22, enabling the upper slots to be inserted into the partition plate 25. The protrusion 251 is inserted into the upper slot 221; the position and shape of the lower protrusion 252 match the lower slot 222 so that it can be inserted into the lower slot 222; when the partition 25 is installed, the partition 25 is inserted into the mold cavity 23 from top to bottom, and the upper protrusion 251 and lower protrusion 252 on both sides of the partition 25 are respectively inserted into the upper slot 221 and lower slot 222 of the corresponding side plate 22. At this time, the upper protrusion 251 is limited by the groove wall of the upper slot 221, and the lower protrusion 252 is limited by the groove wall of the lower slot 222. The horizontal and vertical directions of the partition 25 are constrained, thereby achieving the purpose of firmly fixing the partition 25 in the mold cavity 23.

[0045] Preferably, in this embodiment, the lower groove 222 does not extend all the way to the bottom plate 21. Its lower groove edge is significantly higher than the upper surface of the bottom plate 21. Thus, on the inner wall of the second side plate 28, between the lower groove edge of the lower groove 222 and the upper surface of the bottom plate 21, a complete, uninterrupted closed section 26 is formed. When the partition plate 25 is installed in place and its lower protrusion 252 is inserted into the lower groove 222, the lower edge of the partition plate 25 just overlaps the inner surface of this closed section 26, raising the position of the lower groove 222. Furthermore, the wall material of the second side plate 28 itself blocks the direct channel between the bottom of the cover plate forming cavity 24 and the groove opening of the lower groove 222, effectively reducing the possibility of grout leakage from the lower groove 222. Structurally, this effectively suppresses the common problem of grout leakage at the bottom corner, improves the forming quality of the cover plate 2, and reduces material waste.

[0046] Further, see Figure 1 and Figure 2 For the pouring and compaction mechanism 10, which is located at the beginning of the production line, it is responsible for feeding and compacting the above-mentioned cover plate forming mold 20. The pouring and compaction mechanism 10 mainly includes a feeding device and a vibrating table 70. The feeding device can be a mobile hopper or a screw conveyor, and its outlet can move and cover the entire area above the cover plate forming mold 20 so as to evenly distribute the fresh concrete slurry into each parallel cover plate forming cavity 24. The vibrating table 70 serves as a bearing platform and is located below the cover plate forming mold 20. The vibrating table 70 is used to support the entire cover plate forming mold 20 during and after the feeding process to apply high-frequency vibration to the forming mold, eliminate internal voids and surface honeycomb pitting, thereby significantly improving the density and strength of the concrete and ensuring the structural quality of the formed cover plate 2.

[0047] For the conveying mechanism 40, it serves as the logistics link connecting various processes such as pouring, static stopping, and demolding. The conveying mechanism 40 is planned to have a pouring station 41, a static stopping station 43, and a demolding station 42. As a specific implementation, the conveying mechanism 40 can be a powered roller conveyor, which consists of multiple rows of parallel rollers. The rollers are driven to rotate by a motor, and the friction between the rollers and the mold base plate 21 is used to smoothly transport the cover plate forming mold 20. The pouring mechanism 10 corresponds to the pouring station 41, and the vibrating table 70 is installed at this station to discharge and vibrate the cover plate forming mold 20 at the pouring station 41.

[0048] Therefore, in a specific workflow, after the entire cover plate forming mold 20 has been vibrated and compacted, it is conveyed away from the pouring station 41 by the conveying mechanism 40 while keeping all the cover plates 2 in their forming cavities and maintaining their arrangement. It is then smoothly transported along the roller conveyor line to the static stopping station 43. In the static stopping station 43, the cover plate forming mold 20 is placed statically, and the concrete slurry inside undergoes initial setting and final setting processes simultaneously while maintaining a parallel arrangement, until it solidifies to a strength sufficient for demolding. Once the cover plates 2 reach the preset demolding strength... After the mold is solidified, the conveying mechanism 40 starts again, transporting the cover plate forming mold 20 from the stationary stop 43 to the demolding stop 42. In this application, the entire conveyor line operates in an assembly line manner, which circulates the heavy molds that originally required a lot of manual handling, realizes the automation of logistics, reduces the waiting time between processes and the damage during handling. At the same time, the station-type assembly line layout clarifies the spatial division of each process, making parallel operation possible. Meanwhile, the roller conveyor method is stable and reliable, with little impact on the bottom of the mold, ensuring the static stability of the concrete in the stage before it is fully solidified.

[0049] Furthermore, in order to connect the stationary stop 43 and the demolding stop 42 and to enable flexible heavy-duty handling between them, a transfer mechanism 50 is set between the demolding stop 42 and the stationary stop 43. The transfer mechanism 50 is specifically a lifting device and can adopt equipment structures such as column-type or gantry-type jib cranes. Its working range can completely cover the stationary stop 43 and the demolding stop 42.

[0050] Specifically, to improve hoisting efficiency and coverage, and to optimize equipment layout to avoid interference and waste, the transfer mechanism 50 includes a first transfer mechanism 51 and a second transfer mechanism 52. The first transfer mechanism 51 has a first rotation radius 511, and the area swept by its boom during rotation forms a first circular working area. This first circular working area covers the position of the stationary stop 43, allowing the first transfer mechanism 51 to lift the cover plate forming mold 20 from the stationary stop 43 and transfer it from the roller of the conveying mechanism 40 to the ground for stationary stop. After stationary stop, the cover plate forming mold 20 that meets the demolding standard is re-lifted onto the roller of the conveying mechanism 40 by the first transfer mechanism 51 and transferred to the demolding stop 42 to complete the demolding of the cover plate 2. The second transfer mechanism 52 has a second rotation radius 522, and when it rotates, it forms a second circular working area, which covers the position of the demolding stop 42, allowing the second transfer mechanism 52 to hoist the demolded cover plate 2 as a whole to the subsequent packaging stop for packaging.

[0051] Preferably, the circular working area of ​​the first transfer mechanism 51 and the circular working area of ​​the second transfer mechanism 52 are tangent in the plane, which maximizes the use of the working space and effectively avoids interference and conflict between the first transfer mechanism 51 and the second transfer mechanism 52.

[0052] Furthermore, after the cover plate forming mold 20 is hoisted to the demolding station 42, it enters the demolding process, see [link to relevant documentation]. Figures 8 to 11 A demolding bracket 60 is provided at demolding station 42. The demolding bracket 60 includes an L-shaped rigid frame structure. One side of the L-shape forms an insertion part 61 for insertion and positioning, and the other side forms a support part 62 for providing support. The insertion part 61 and the support part 62 are fixedly connected to each other at a certain angle, usually an obtuse angle slightly greater than 90 degrees, but can also be set as a right angle structure under certain working conditions. When demolding the cover plate 2, first disconnect the connection between the side plate 22 and the bottom plate 21 of the cover plate forming mold 20, and remove part or all of the side plate 22, such as... Figure 8 and Figure 9As shown, or with the side plate 22 in a loose state, the demolding bracket 60 is operated so that its insertion part 61 is smoothly inserted under the bottom plate 21 of the cover plate forming mold 20 until the insertion part 61 contacts or reaches the lower surface of the bottom plate 21. At this time, the entire support part 62 stands on one side of the mold and extends tilted upwards and outwards from the mold. The insertion part 61 is inserted under the bottom plate 21, providing a stable fulcrum for the entire bracket and restricting the movement of the bracket under force.

[0053] Then, the operator manually or with the aid of tools sequentially demolds the cover plates 2 within each of the arranged cover plate forming cavities 24, see [link to relevant documentation]. Figure 10 and Figure 11 Specifically, starting from the end of the cover plates 2 arranged in an orderly manner near the support 62, the top of the first cover plate 2 is pried open, causing it to rotate around the bottom edge and gradually move away from the vertical state, becoming an inclined state tilted towards the support 62. The angle of inclination of the cover plate 2 gradually increases until its back rests against the support 62 of the demolding bracket 60. At this time, the support 62 provides a stable support point for the inclined cover plate 2, preventing it from continuing to tip over and keeping the cover plate 2 in a certain inclined posture. When the cover plate 2 is in an inclined state, the partition 25, which was originally in close contact with the side of the cover plate 2, creates a separation gap with the surface of the cover plate 2. The tightness of its contact is greatly released, and the operator can easily pull the loose partition 25 upward, thereby completing the separation of the cover plate 2 from the partition 25. At this point, the cover plate 2 has completed demolding, but it is not moved away in isolation. Instead, it leans against the bracket at an inclination, still maintaining a roughly parallel arrangement with the adjacent undemolded cover plates 2. Following the above procedure, similarly, the process is performed sequentially along the arrangement direction of the multiple cover plates 2: the next cover plate 2 is pried open to tilt and rest against the support 62, and the partition 25 on its other side is removed. This process is repeated until all partitions 25 in the cover plate forming cavities 24 are removed one by one. The demolding bracket 60 provides a positioning fulcrum and stable support surface for demolding, preventing the cover plate 2 from tipping over and being damaged when the partitions 25 are pulled out. This solves the problem of maintaining the stable position of other cover plates 2 when removing partitions 25 one by one from a multi-cavity mold, making parallel demolding possible. Furthermore, the structure is relatively simple and the operation is highly feasible.

[0054] Furthermore, after all the partitions 25 have been completely removed, the multiple fully formed independent cover plates 2 are in an inclined state, leaning against the support part 62 of the demolding bracket 60 in parallel with each other, forming an inclined but orderly arrangement of cover plates 2. At this time, the final straightening operation is performed. Using manual or auxiliary mechanisms, starting from one end of the arrangement, force is applied together in a direction perpendicular to the bottom surface to push the entire group of inclined cover plates 2 in a whole form, rotating around its bottom edge from the inclined state to the vertical state. Since all the cover plates 2 are close to each other and parallel, the rotating action lifts the cover plates 2 as a whole, so that the multiple cover plates 2 are arranged vertically and closely in parallel on the demolding station 42 to form a whole cover plate 2.

[0055] After demolding and alignment, multiple cover plates 2 stand as a single unit at the demolding station 42. At this point, the second transfer mechanism 52 can transfer the multiple cover plates 2 as a whole to the subsequent packaging station for final packaging. Figure 12 As shown, specifically, the second transfer mechanism 52 can be a gantry manipulator or a truss manipulator, with a clamping assembly 53 installed at its end. The clamping assembly 53 includes two clamping parts, which are arranged opposite each other and the distance between them is adjustable. They are typically driven by hydraulic cylinders, pneumatic cylinders, gravity, or electric push rods to open and close. The two clamping parts are respectively located on the outer sides of two cover plates 2 at both ends of the parallel arrangement direction. After the second transfer mechanism 52 moves into position, the two clamping parts are in an open state and are respectively placed on the outer sides of both ends of the cover plate 2. Subsequently, the second transfer mechanism 52 is activated, causing at least one clamping part to move toward the center along the arrangement direction of the multiple cover plates 2, or two clamping parts to move toward each other. During the movement, the clamping part first contacts the side of the outermost cover plate 2 and continuously applies a pushing force. This pushing force is transmitted between the cover plates 2, pushing all the multiple cover plates 2 to move closer to each other. The slight gaps that may still exist after returning to the center are completely eliminated under the clamping force, and the surfaces of adjacent cover plates 2 are tightly fitted together. At this time, the two clamping parts firmly clamp the entire compressed cover plate 2 group from both ends. While maintaining the clamping force and keeping the adjacent cover plates 2 in contact with each other, the second transfer mechanism 52 lifts and moves the entire assembly, transferring this single cover plate 2 group, which consists of multiple cover plates 2 and has no internal gaps, to the static packaging station in one go. By integrating multiple independent cover plates 2 into a whole, the stability during the transfer process is greatly enhanced, preventing the shaking, collision and tipping of a single cover plate 2. At the same time, the transfer efficiency is effectively improved by handling multiple cover plates 2 at one time compared to repeatedly handling a single piece.

[0056] Furthermore, this application also provides a working method for a cover plate production system 1. This method is applicable to the cover plate production system 1 described in any of the above embodiments, and its overall workflow is as follows: Step S10: Mold assembly and casting. The four side plates 22 of the cover plate forming mold 20 are connected to the periphery of the base plate 21 at predetermined positions. The adjacent first side plates 27 and second side plates 28 are firmly locked by inserting locking rods 29 into the first slots 271 and the second slots 281 and tightening nuts 291. Subsequently, the upper protrusions 251 and lower protrusions 252 on the multiple partitions 25 are aligned with the upper slots 221 and the lower slots 222 on the side plates 22, and inserted one by one, so that the base plate 21, the multiple side plates 22, and the multiple partitions 25 together form multiple parallel and upward-facing independent cover plate forming cavities 24. After the mold assembly is completed, the whole assembly is placed on the vibration table 70 of the casting station 41. The material feeding device is activated to simultaneously feed material into multiple cover plate forming cavities 24, allowing concrete slurry to fill each cavity. At the same time as or after feeding, the vibrating table 70 is activated to apply vibration to the entire cover plate forming mold 20, causing the concrete to fill densely and the gas to be discharged. In this way, multiple cover plates 2 are formed in parallel within the same cover plate forming mold 20.

[0057] Step S20: Perform overall static curing. After pouring, maintain the connection between the side plate 22 and the bottom plate 21, and keep the position of the partition plate 25 in the mold cavity 23 unchanged, that is, maintain the original parallel arrangement of the entire mold and the multiple cover plates 2 inside. Through the transfer mechanism 50 and the conveying mechanism 40, the entire heavy cover plate forming mold 20 is smoothly transferred from the pouring station 41 to the static curing station 43 until the concrete gradually solidifies and reaches the preset demolding strength.

[0058] Step S30: Demolding operation. At the demolding station 42, the following sub-steps are performed: Step S31: Insert the insertion part 61 of the demolding bracket 60 under the bottom plate 21 of the cover plate forming mold 20, ensuring that the demolding bracket 60 is stably positioned, with its support part 62 located on one side of the predetermined tilting direction of the multiple cover plates 2. Step S32: Subsequently, the operator demolds each cover plate 2 in the cover plate forming cavity 24 sequentially, starting from the end closest to the support part 62, along the arrangement direction of the multiple cover plates 2. Specifically, a cover plate 2 is tilted until its back side safely rests against the support part 62 of the demolding bracket 60. After a separation gap is created between the cover plate 2 and the corresponding partition 25, the loosened partition 25 is removed upwards. This action is repeated to remove all the partitions 25 sequentially. During this step, the demolding bracket 60 continuously provides support for all the demolded cover plates 2 to prevent them from tipping over. Step S33: After confirming that all partitions 25 have been removed, the operator pushes the tilted and parallel cover plates 2 from the side, rotating the multiple cover plates 2 against the demolding bracket 60 as a whole from the tilted state to the vertical state. Thus, a whole cover plate 2 consisting of multiple vertical, parallel and close-to-each-other cover plates 2 is formed at the demolding station 42.

[0059] The process then proceeds to step S40: clamping and transferring the entire cover plate 2 assembly. The second transfer mechanism 52 is activated, moving its two clamping parts to both ends of the entire cover plate 2 at the demolding station 42. The two clamping parts are aligned with the two cover plates 2 located at opposite ends of the arrangement direction. Subsequently, the clamping parts are driven to retract inwards along the arrangement direction, and the clamping force is transmitted sequentially through the cover plates 2, pressing the multiple cover plates 2 tightly together, completely eliminating any remaining minor gaps between adjacent cover plates 2 after demolding. After the multiple cover plates 2 reach a tightly fitted state, the second transfer mechanism 52 transports this tightly fitted cover plate 2 assembly as a single unit in space to the predetermined packaging station. This transforms the loose multiple cover plates 2 into a compact unit before transfer, ensuring a smooth and safe transfer process, preventing damage to individual cover plates 2 due to shaking, and simplifying the subsequent packaging process from multiple loose plates to a single unit, creating favorable conditions for the packaging process.

[0060] Step S50: Package the cover plate 2 as a whole. At the packaging station, after being released to a specific packaging platform by the second transfer mechanism 52, the multiple cover plates 2 are kept in close contact with each other and their original parallel arrangement remains unchanged. Using equipment such as strapping machines and stretch film packaging machines, the whole assembly of these multiple cover plates 2 is strapped or wrapped. The packaging material tightly binds the entire cover plate 2 group into a handling unit, thereby ensuring mutual support and protection of the multiple cover plates 2 inside during the logistics process. This avoids the traditional mode of wrapping and stacking individual prefabricated cover plates 2 one by one, and realizes intensive processing from production to delivery.
