[0002] At present, in the production line of precast concrete components, production is usually carried out in a cyclic flow operation mode. However, during the production process, the precast components on the mold table need to be cured. In the production lines of related technologies, the mold table carrying the precast concrete components is usually placed in a curing kiln, and curing operations are carried out in the curing kiln.

[0003] In related technical solutions, generally, the curing kiln has a plurality of independent curing chambers in the height and width directions. The operating mechanism transports the mold table carrying the precast concrete components to the position where the curing kiln is located, and the stacking mechanism stacks the mold tables one by one into the curing chambers. The mold tables are stored in the curing chambers and curing operations are carried out. However, in the production line of this method, the curing kiln occupies a large space and has a limited storage capacity, reducing the space utilization rate of the factory building. Moreover, the production rhythm is limited by the stacking rhythm of the stacking mechanism, reducing the production efficiency. Summary of the Invention

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] The following combines Figures 1 to 10 , and describes the embodiments of the present invention.

[0032] The present invention provides a production line for precast concrete components, including a production line 2 for manufacturing precast concrete components on a molding table 1, a plurality of molding tables 1 adapted to flow on the production line 2, a curing system 3, and a stacking system. Specifically, the curing system 3 is formed with a curing passage 30, and the curing passage 30 is connected to the head and tail ends of the production line 2. The molding table 1 is adapted to circulate between the production line 2 and the curing passage 30. The stacking system includes two demounting and stacking machines 4, and the two demounting and stacking machines 4 are respectively arranged corresponding to the head end 2a and the tail end 2b of the production line 2, and are both connected to the curing passage 30. Among them, the demounting and stacking machine 4 corresponding to the head end 2a is adapted to unstack the molding tables 1 flowing out of the curing passage 30 and convey them to the production line 2; the demounting and stacking machine 4 corresponding to the tail end 2b is adapted to stack the molding tables 1 flowing out of the production line 2 and convey them to the curing passage 30.

[0033] Using the technical solution of the present invention, firstly, the curing system 3 forms a curing channel 30, adopting a channel-type curing method. With the cooperation of the stacking and unstacking machine 4, the curing channel 30 can realize the channel-type flow curing of the whole stack of formworks 1. Compared with a curing kiln with multiple independent curing bins in the height and width directions, the curing channel 30 of the present invention occupies less space, can save the space in the factory building, and its own weight is greatly reduced, and the requirements for the infrastructure of the factory building are also lower, which is convenient for flexible layout in factory buildings of various specifications. Secondly, the curing channel 30 is connected to the head and tail ends of the production line 2. The stacking and unstacking machine 4 located at the tail end 2b of the production line 2 directly transports the stacked whole stack of formworks 1 into the curing channel 30, and the whole stack of formworks 1 after curing is transferred back to the production line 2 through the stacking and unstacking machine 4 located at the head end 2a of the production line 2, saving the transfer or hoisting steps of the formwork 1 between the curing system 3 and the production line 2, thereby improving the production efficiency.

[0034] Therefore, the precast concrete component production line of the present invention has low requirements for the space of the factory building and high production efficiency, and is convenient for adapting to factory buildings of various specifications and fast-paced production.

[0035] It can be understood that the layout mode of the precast concrete component production line of the present invention is relatively flexible, and there are various possible layout modes. The following will be described in conjunction with three embodiments.

[0036] Embodiment 1

[0037] As Figure 1 , in this embodiment, the production line 2 and the curing channel 30 are arranged in parallel. Two stacking and unstacking machines 4 are respectively movably arranged at both ends of the production line 2 and the curing channel 30, and the stacking and unstacking machines 4 are all adapted to move between a first position and a second position. In the first position, the stacking and unstacking machine 4 is docked with the production line 2. In the second position, the stacking and unstacking machine 4 is docked with the curing channel 30.

[0038] Among them, Figure 1 the arrow direction shown in is the flow direction of the formwork 1 in the production line 2 and the curing channel 30. In this embodiment, the flow direction of the formwork 1 on the production line 2 is opposite to the flow direction in the curing channel 30. During actual production, the stacking and unstacking machine 4 located at the tail end 2b of the production line 2 stacks the formwork 1 in the first position, drives the whole stack of formworks 1 to move to the second position, and transports the whole stack of formworks 1 into the curing channel 30; the whole stack of formworks 1 completes the curing operation during the flow process along the curing channel 30 and flows into the stacking and unstacking machine 4 located at the head end 2a of the production line 2, and this stacking and unstacking machine 4 unstacks the whole stack of formworks 1, and the formworks 1 flow into the production line 2 one by one.

[0039] In this embodiment, the arrangement of a single-column curing channel 30 is adopted, which can save the space in the width of the factory building, facilitate the arrangement of the production line of process components (such as trusses, etc.) beside the production line 2, or reserve the storage space for the mold table 1 and precast components, improve the convenience of each process operation, and facilitate the realization of automated production.

[0040] Specifically, the stacking system further includes two guiding tracks 5. The two guiding tracks 5 are respectively arranged at both ends of the production line 2 and the curing channel 30, and the guiding channels extend in a direction perpendicular to the parallel direction of the production line 2 and the curing channel 30, so as to cover the first position and the second position. Two unstacking and stacking machines 4 are respectively movably arranged on the two guiding tracks 5 to move between the first position and the second position along the guiding tracks 5. As Figure 1 shown, the arrow direction on the guiding track 5 is the moving direction of the unstacking and stacking machine 4. The cooperation of the guiding track 5 and the unstacking and stacking machine 4 is adopted to realize the transfer of the mold table 1 between the production line 2 and the curing channel 30. The structure is not only simple, but also the moving stroke of the unstacking and stacking machine 4 is small, which is convenient for improving the production efficiency of the production line.

[0041] Furthermore, as Figures 5 to 9 shown, in this embodiment, the unstacking and stacking machine 4 includes a vehicle frame 41, a first roller assembly 42 and a lifting structure 43. The vehicle frame 41 includes a base 411, and the base 411 is adapted to carry the mold table 1. The first roller assembly 42 and the lifting structure 43 are both arranged on the base 411. Among them, the first roller assembly 42 is adapted to receive or output the mold table 1. The driving end 4321 of the lifting structure 43 can be connected to or separated from the mold table 1. When the driving end 4321 of the lifting structure 43 is connected to the mold table 1, the lifting structure 43 can drive the mold table 1 to rise or fall relative to the base 411.

[0042] When stacking the mold table 1, the lifting structure 43 can drive the first mold table on the first roller assembly 42 to rise, so that the second mold table on the production line 2 continues to flow into the first roller assembly 42. At this time, the lifting structure 43 descends, places the first mold table on the second mold table, and drives the first mold table and the second mold table to rise, and the next mold table 1 continues to flow into the first roller assembly 42. That is to say, the unstacking and stacking machine 4 in this embodiment adopts a stacking method from bottom to top. The lifting stroke of the upper mold table 1 is small, and the stacking efficiency is high, further ensuring the production efficiency. Similarly, during the unstacking operation, the unstacking and stacking machine 4 drives the upper mold table 1 to rise until it is separated from the bottommost mold table 1, and the first roller assembly 42 outputs the bottommost mold table 1, that is, adopts an unstacking direction from bottom to top, and the unstacking efficiency is high.

[0043] It can be understood that in this embodiment, the stack-unstacking machine 4 is arranged at both ends of the production line 2 and is connected between the production line 2 and the curing channel 30. Therefore, the first roller assembly 42 extends along the flow direction of the mold table 1 in the production line 2 and the curing channel 30, so as to facilitate docking with the production line 2 and the curing channel 30. And the rolling axis of the first roller assembly 42 is perpendicular to the flow direction of the mold table 1 to generate a driving force in the flow direction of the mold table 1 to receive or output the mold table 1.

[0044] Exemplarily, two groups of the first roller assemblies 42 can be arranged side by side and at intervals, respectively supporting at both ends in the width direction of the mold table 1. The first roller assembly 42 includes a plurality of driving wheels and a plurality of guiding wheels arranged at intervals, and the driving wheels and the guiding wheels are arranged on the base 411. Among them, the rolling axis of the driving wheel is perpendicular to the flow direction of the mold table 1.

[0045] Specifically, the vehicle frame 41 further includes four columns 412, and the four columns 412 are connected above the base 411 and are located at the four corners of the base 411. Four groups of lifting structures 43 are correspondingly arranged, and the four groups of lifting structures 43 are correspondingly arranged on the columns 412 one by one. That is to say, the four groups of lifting structures 43 are arranged on the base 411 through the four columns 412. As Figure 5 and 6 shown, the four columns 412 enclose a rectangular shape, and a stacking and unstacking space 40 is formed between the four columns 412. The stack-unstacking machine 4 completes the stacking and unstacking of the mold table 1 in the stacking and unstacking space 40. Since the lifting structure 43 is arranged on the column 412 and can drive the mold table 1 to lift on both sides of the mold table 1 without occupying the space above the mold table 1, the stack-unstacking machine 4 occupies a relatively small height space.

[0046] Furthermore, in this embodiment, as Figure 7 shown, the lifting structure 43 includes a driving member 431 and a lifting member 432. The driving member 431 is installed on the column 412, and the driving member 431 is adapted to drive the lifting member 432 to lift when extending or shortening. The driving end 4321 is telescopically arranged on the lifting member 432 to connect or separate from the mold table 1.

[0047] Among them, the driving member 431 can be a cylinder, a linear motor, a hydraulic rod, a lead screw, etc., as long as it can realize the function of driving the lifting member 432 to lift. Exemplarily, the driving member 431 is an oil cylinder, the cylinder body of the oil cylinder is installed on the top of the column 412, and the piston rod of the oil cylinder is connected to the lifting member 432, and the lifting member 432 is driven to lift by the telescopic movement of the piston rod. The lifting member 432 can also be a cylinder, a linear motor, a hydraulic rod, a lead screw, etc., as long as it can realize the telescopic movement of the driving end 4321.

[0048] Exemplarily, as Figure 10As shown, a support structure 11 is provided at the edge of the mold table 1, and a clamping hole 12 is provided on the support structure 11 facing outward. The lifting member 432 is arranged corresponding to the support structure 11 of the mold table 1. When the driving end 4321 extends, it can be inserted into the clamping hole 12 to connect with the mold table 1. When the driving end 4321 retracts, it can disengage from the clamping hole 12 to disconnect from the mold table 1.

[0049] Furthermore, in this embodiment, as Figure 6 and Figure 8 shown, the disassembling and stacking machine 4 further includes two sets of synchronization components 44. In the flowing direction of the mold table 1, each set of synchronization components 44 is connected to the two lifting structures 43 on the two columns 412 on the same side to drive the two lifting structures 43 on the same side to lift synchronously, ensuring the stability of the lifting of the mold table 1.

[0050] Exemplarily, the synchronization component 44 includes a synchronization shaft 441 and transmission members 442. The synchronization shaft 441 is arranged on the base 411. The two transmission members 442 are respectively connected to the lifting members 432 of the two lifting structures 43, and the synchronization shaft 441 is in transmission connection between the two transmission members 442. Among them, the synchronization shaft 441 is arranged on the base 411 through the column 412. Specifically, both ends of the synchronization shaft 441 are fixedly connected to the two columns 412 on the same side, and gears are provided at both ends of the synchronization shaft 441. The transmission members 442 are racks, and the two racks are respectively fixedly connected to the lifting members 432 of the two lifting structures 43 on the same side. The gears at both ends of the synchronization shaft 441 are respectively meshed and matched with the two racks.

[0051] Furthermore, in this embodiment, in the disassembling and stacking machine 4, the vehicle frame 41 further includes a wheel set 413, which is arranged at the bottom of the base 411. The rolling axis of the wheel set 413 is perpendicular to the rolling axis of the first roller assembly 42, that is, the rolling axis of the wheel set 413 is along the flowing direction of the mold table 1, so as to be able to move perpendicular to the flowing direction of the mold table 1.

[0052] It can be understood that the disassembling and stacking machine 4 is movably arranged on the guiding track 5 through the wheel set 413.

[0053] Furthermore, a positioning pin can also be provided on the base 411. The positioning pin is arranged corresponding to the support structure 11 of the mold table 1, and the positioning end of the positioning pin is telescopically arranged. When the positioning end extends, it can abut against the bottom of the support structure 11 to fix the mold table 1 at a predetermined position; when the positioning end retracts, the fixation of the mold table 1 is released. It can be understood that there are multiple support structures 11 of the mold table 1, and there can be one positioning pin or multiple corresponding positioning pins, as long as the positioning and fixing functions of the mold table 1 can be realized.

[0054] Further, the unstacking machine 4 may be provided with a fixed bolt, which is telescopically arranged on the base 411 and is adapted to extend or retract towards the foundation to fix or release the fixation of the unstacking machine 4 to the foundation.

[0055] Among them, the positioning bolt and the fixed bolt are similar in structure to the lifting member 432, and will not be elaborated here.

[0056] Further, the above-mentioned curing system 3 may include a heat preservation board and temperature and humidity pipelines. The heat preservation board encloses the above-mentioned curing channel 30, and the temperature and humidity pipelines are arranged inside the curing channel 30. In order to ensure the curing effect, kiln doors may also be provided at both ends of the curing channel 30.

[0057] Further, the above-mentioned production line 2 can be adaptively adjusted according to the type of precast concrete components produced. Exemplarily, a demolding system is provided at the head end 2a of the production line 2. The mold table 1 flowing out of the curing channel 30 is transferred to the head end 2a of the production line 2, and the demolding system demolds the cured precast component finished product. Moreover, the production line 2 may also include stations such as cleaning, mold laying, oil spraying, steel bar feeding, concrete placing, and vibration. Through the transfer of the mold table 1 on the production line 2, the manufacturing of precast concrete components on the mold table 1 is completed.

[0058] Further, as Figure 1 shown, the precast concrete component production line of the present invention further includes a roller system 7, and the roller system 7 extends and is arranged inside the curing channel 30 and the production line 2. Specifically, the roller system 7 includes a plurality of driving wheels and a plurality of guiding wheels arranged at intervals along the extending direction. The driving wheels and the guiding wheels are arranged on the ground and are used to drive the mold table 1 to circulate and transfer inside the curing channel 30 and the production line 2. Among them, the spacing and quantity of the guiding wheels and the driving wheels can be adaptively arranged according to the size and load of the mold table 1, and the local spacing only needs to satisfy the smooth transfer of the mold table 1 and have sufficient supporting rigidity.

[0059] Embodiment 2

[0060] As Figure 2 and Figure 4 shown, in this embodiment, the production line 2 and the curing channel 30 are arranged in parallel. The difference between this embodiment and Embodiment 1 is that in this embodiment, multiple curing channels 30 are arranged side by side, and the moving track of the unstacking machine 4 covers multiple curing channels 30 to have sufficient curing capacity to meet the curing requirements of the production line 2. Exemplarily, two curing channels 30 are arranged side by side, and each curing channel 30 is provided with a plurality of curing stations.

[0061] Further, in this embodiment, multiple production lines 2 are arranged side by side, and the moving track of the unstacking machine 4 covers multiple production lines 2 to realize multi-line parallel production and improve production efficiency.

[0062] Further, since the curing system 3 of the present invention occupies less space in height, a platform layer can also be provided at the top of the curing passage 30, and this platform layer can be used to store intermediate components and the like.

[0063] In this embodiment, the setting manner of the unstacking system is the same as that in the first embodiment, and will not be elaborated here.

[0064] Embodiment Three

[0065] As Figure 3 , the difference between this embodiment and the first and second embodiments lies in the layout manner of the production line 2 and the curing passage 30. In this embodiment, a head end 2a and a tail end 2b are formed on one side of the production line 2, that is to say, the head end 2a and the tail end 2b are located on the same side. A plurality of curing passages 30 are arranged in parallel and are provided on the side of the production line 2 where the head end 2a and the tail end 2b are located. The stacking system includes a first transverse movement mechanism 6 and two unstacking and stacking machines 4, and the two unstacking and stacking machines 4 are respectively arranged corresponding to the head end 2a and the tail end 2b of the production line 2. The first transverse movement mechanism 6 is docked between the curing passage 30 and the two unstacking and stacking machines 4, and the first transverse movement mechanism 6 extends in the side-by-side direction of the plurality of curing passages 30 to transfer the mold table between the curing passage and the unstacking and stacking machine. Among them, the unstacking and stacking machine 4 corresponding to the head end 2a is adapted to unstack the mold table 1 flowing out of the curing passage 30 and convey it to the production line 2; the unstacking and stacking machine 4 corresponding to the tail end 2b is adapted to stack the mold table 1 flowing out of the production line 2 and convey it to the curing passage 30.

[0066] In this embodiment, firstly, the head end 2a and the tail end 2b of the production line 2 are located on the same side, and a plurality of curing passages 30 are integrated on one side of the production line 2. The overall layout of the production line is compact, which can make full use of the space of the factory building and improve the space utilization rate. Secondly, the channel-type curing method is adopted, and with the cooperation of the unstacking and stacking machine 4 and the first transverse movement mechanism 6, the curing passage 30 can realize the channel-type flow curing of the whole stack of mold tables 1, which improves the flow rhythm of the mold table 1 between the curing system 3 and the production line 2. Moreover, the first transverse movement mechanism 6 is docked between the plurality of curing passages 30 and the two unstacking and stacking machines 4. Compared with the first and second embodiments, in this embodiment, the moving time of the unstacking and stacking machine 4 between the curing passage 30 and the production line 2 is saved, and the flow rhythm of the mold table 1 between the curing system 3 and the unstacking and stacking machine 4 is improved, thereby improving the production efficiency.

[0067] Therefore, the layout of the concrete precast component production line in this embodiment is compact, the space utilization rate is improved, the space requirement for the factory building is low, and the production efficiency is high, which is convenient for adapting to various specifications of factory buildings and fast-paced production.

[0068] It should be noted that in this embodiment, the two unstacking machines 4 are respectively fixedly arranged at the head end 2a and the tail end 2b of the production line 2. Specifically, the unstacking machines 4 can be fixedly arranged by using the above-mentioned fixed pins.

[0069] Furthermore, in this embodiment, the curing system includes a curing kiln, and multiple curing channels are arranged in the curing kiln. The multiple curing channels are centrally arranged on one side of the production line and integrated in the same curing kiln, which is beneficial to reducing the curing cost and further improving the space utilization rate.

[0070] Furthermore, the curing channels adopt the method of directly stacking and curing the formwork tables, saving the height space of the factory building. Therefore, a platform layer can also be provided at the top of the curing kiln for placing intermediate components, etc., to further improve the space utilization rate.

[0071] Furthermore, the first transverse movement mechanism 6 includes a transverse movement track and a transverse movement trolley. The transverse movement track extends in the parallel direction of the multiple curing channels, and the transverse movement trolley is movably arranged on the transverse movement track, and the movement track of the transverse movement trolley covers the multiple curing channels. In this embodiment, the transverse movement trolley can be docked with the two unstacking machines 4. The transverse movement trolley is used to sequentially send the stacked whole stack of formwork tables 1 into a plurality of curing channels 30 arranged side by side, and transfer the whole stack of formwork tables 1 after curing to the unstacking machine 4 located at the head end 2a of the production line 2 for unstacking. The operation of the transverse movement trolley does not affect the stacking and unstacking operations of the unstacking machine 4, and the transverse movement trolley is located between the curing channels 30 and the production line 2, with a small movement stroke and does not affect the production rhythm, thereby being able to ensure the production efficiency.

[0072] Exemplarily, each curing channel 30 is provided with two curing stations, and one curing channel 30 can realize the curing of double stacks of formwork tables 1. It can be understood that multiple curing stations can also be provided.

[0073] Furthermore, the production line 2 adopts the method of being serially arranged by multiple sub-production lines to save the factory building space. Exemplarily, the multiple sub-production lines are arranged side by side on one side of the curing channels 30, and a second transverse movement mechanism 21 and a third transverse movement mechanism 22 are respectively arranged at both ends of the multiple sub-production lines. The second transverse movement mechanism 21 and the third transverse movement mechanism 22 are used to realize the series connection of the multiple sub-production lines, so that the formwork table 1 can flow between the side-by-side sub-production lines.

[0074] In some embodiments not shown in the figures, in the layout mode of Embodiment 3, the stacking system can also adopt the method of cooperating the guiding track 5 and the unstacking machine 4 as in Embodiment 1 to realize the movable setting of the unstacking machine 4 and be able to be respectively docked with the production line 2 and the curing channels 30.

[0075] In the concrete precast component production line of the present invention, the steps of the whole stack flow and curing operation of the formwork table 1 are as follows:

[0076] S1: The unstacking machine 4 is docked at the tail end 2b of the production line 2 and fixed to the ground by fixed pins.

[0077] S2: After the mold table 1 flows into the unstacking machine 4, the positioning end of the positioning pin on the stacking machine abuts against the support structure 11 of the mold table 1 to ensure the accurate docking position of the mold table 1.

[0078] S3: The lifting structure 43 is at the lowest position, and the driving end 4321 of the lifting structure 43 is connected to the mold table 1 to drive the mold table 1 to rise.

[0079] S4: The next mold table 1 flows into the unstacking machine 4, and the operation of S1 is also performed.

[0080] S5: The lifting structure 43 drives the mold table 1 to descend above the lower mold table 1. After the driving end 4321 is separated from the mold table 1 and the upper mold table 1 is placed above the lower mold table 1, the lifting structure 43 runs to the lowest position.

[0081] S6: Repeat the operations of S3 to S5 until the stacking reaches the predetermined number of layers.

[0082] S7: When the mold table 1 is stacked to the predetermined number of layers, the fixed pins retract and move to dock with the curing channel 30, and the fixed pins are fixed to the ground again.

[0083] S8: The stacked mold tables 1 on the unstacking machine 4 are transferred into the curing channel 30 under the action of the first roller assembly 42 for curing.

[0084] S9: After curing, the stacked mold tables 1 are transferred out of the curing channel 30 and enter the unstacking machine 4 at the head end 2a of the production line 2.

[0085] S10: The lifting structure 43 runs to the position of the second-layer mold table 1 from the bottom. The driving end 4321 is connected to the second-layer mold table 1 from the bottom, and the lifting structure 43 drives the mold tables 1 above the second layer to rise.

[0086] S11: The first-layer mold table 1 at the bottom flows out, and the lifting structure 43 runs to the bottommost position, and the mold tables 1 above the second layer are placed on the first roller assembly 42.

[0087] S12: Repeat the operations of S10 to S11 until all the mold tables 1 flow away.

[0088] In summary, the precast concrete component production line provided by the present invention mainly adopts a production method of stacking, transferring and curing. In cooperation with the unstacking machine 4, it can achieve multi-scheme production layouts, highlighting the advantages of small layout space, fast production rhythm, high space utilization rate, and low cost, and can achieve an optimal configuration of production efficiency and input cost in actual production.
