Description

Technical Field

[0001] This invention relates to the field of conveyor lines for pouring concrete, and specifically to an energy-saving automated conveyor line for pouring precast building components. Background Technology

[0002] As is well known, precast building components are building parts that are pre-produced in a factory and then transported to the construction site for assembly. Compared with the traditional cast-in-place method, they have significant advantages such as more stable quality, faster construction, and greater environmental protection and energy saving. To facilitate the high-efficiency production of precast building components, we propose an energy-saving automated casting conveyor line for precast building components.

[0003] A search revealed that Chinese patent application number CN202021618867.0 discloses a powered roller conveyor line, which is roughly described as follows: It includes a side plate, a bearing mounted on the front end of the side plate, a driven shaft fixedly mounted inside the bearing, a roller integrally cast at the front end of the driven shaft, a power shaft integrally cast at the front end of the roller, hubs mounted on both the front and rear of the power shaft, belts fitted to the hubs, a power box mounted on the rear end of the power shaft, an electric telescopic rod fixedly mounted at the lower end of the power box, a motor fixedly mounted on the left side of the front end of the power box, a controller located to the right of the motor, a screw fixed to the front end of the power box, and a mounting bracket mounted on the upper end of the controller. The system includes a warning light and a power cord installed at the bottom of the controller. The power cord connects the controller, motor, electric telescopic rod, and warning light. The motor contains a force sensor, and the force sensor's cable is connected to the controller. Chinese patent application number CN202123439055.7 discloses a concrete transportation system, which is roughly described as including a hopper, a track, and a transport vehicle. The transport vehicle includes a transport frame with wheels that slide with the track. The hopper is connected to the transport frame via a lifting assembly. In use, the system forms a concrete transportation system in the pouring area by setting up the track and the transport vehicle traveling along the track, which can quickly transport concrete.

[0004] While both of the aforementioned existing technical solutions have a conveying function, the former's conveying production line, if applied to the automated casting of precast building components, is more suitable for conveying the cast precast building components. The latter's main function is concrete transportation. However, the automated casting process of precast building components includes not only the auxiliary transportation of precast building components but also the transportation of concrete.

[0024] It should be further explained that an loading and unloading structure is installed inside the underground frame 2. The loading and unloading structure is used for the insertion and removal of the casting mold relative to the insertion frame 7.

[0025] Furthermore, a protective recovery structure is installed within the ground frame 1. This structure is used to recover free water released from the centrifugal casting mold. The protective recovery structure includes an inner support protective frame 23, which is fixedly connected to the ground frame 1.

[0026] In this embodiment, the first servo motor 5, the second servo motor 6, the third servo motor 13, the electric telescopic rod 14, and the electric adjusting rod 19 are all commercially available conventional devices known to those skilled in the art. In this invention, we are simply using them without making any improvements to their structure or function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. Therefore, we will not elaborate on them here.

[0027] In summary, the working principle of this energy-saving precast building component automated casting conveyor line is as follows: Before use, the overall installation of the energy-saving precast building component automated casting conveyor line must be completed. During construction, a foundation pit should be pre-excavated at the installation site. The dimensions of the foundation pit should correspond to the external dimensions of the underground frame 2. After the foundation pit is excavated, the interior of the foundation pit is poured and hardened to ensure the stability of the foundation pit structure and prevent the foundation pit from collapsing after the underground frame 2 is constructed. After the foundation pit construction is completed, the underground frame 2 is installed, followed by the fixed installation of the above-ground frame 1. All mechanical structures are assembled within the underground frame 2 and the above-ground frame 1. After the mechanical structures are installed, the first servo motor 5, the second servo motor 6, the third servo motor 13, the electric telescopic rod 14, and the electric adjusting rod 19 are installed. Power supply and control circuits are installed for the first servo motor 5, the second servo motor 6, the third servo motor 13, the electric telescopic rod 14, and the electric adjusting rod 19 to form the first servo motor 5, the second servo motor 6, the third servo motor 13, the electric telescopic rod 14, and the electric adjusting rod 19. The operation control of the electric telescopic rod 14 and the electric adjusting rod 19 is performed after installation. The energy-saving precast building component automated pouring conveyor line is run under no-load to determine whether the circuit is reliable and whether the corresponding operation control is normal. Then, the guide pipe 38 is connected to the external concrete pump so that the external concrete pump can pump concrete raw materials into the guide pipe 38. The external material pipe 26 is equipped with a recycling container to achieve the auxiliary recovery of free water. The pouring mold is pre-assembled so that the first half mold 31 and the second half mold 32 form a contact fit to form the pouring cavity, so that the insertion pin 41 can be smoothly inserted relative to the insertion groove. The two semi-circular holes 35 are spliced ​​together. Then, the first half mold 31 and the second half mold 32 are simultaneously inserted into the limiting frame 30. If the precast building component needs to be equipped with a steel reinforcement structure, the steel reinforcement structure is pre-set in the cavity formed by the first half mold 31 and the second half mold 32. At the same time, in order to ensure the stability of the position of the steel reinforcement structure in the cavity, specific support structures can also be added in the first half mold 31 and the second half mold 32.

[0028] Furthermore, after the first half mold 31 and the second half mold 32 are inserted relative to the limiting frame 30, the loading and unloading system is activated. The electric telescopic rod 14 extends, driving the lifting frame 11 down to the bottom limit position of the underground frame 2. Then, through an external auxiliary conveyor line, such as a robot or a trolley, the assembled casting mold is moved into the rotating frame 12 while keeping the hook strip 33 facing upwards. Next, the limiting frame 30 is placed into the cantilever frame 18. After the placement of a single casting mold is completed, the third servo motor 13 operates to realize the position switching of multiple cantilever frames 18. With the intermittent movement of multiple cantilever frames 18, casting molds are placed into multiple cantilever frames 18. At the same time, to facilitate the connection of subsequent continuous casting operations, the casting mold forms an insertion passage relative to the cantilever frame 18. During the process, loading is carried out in an alternating manner. After multiple cantilever frames 18 rotate one revolution simultaneously, the loading of multiple casting molds for a single loading is completed. Then, the electric telescopic rod 14 is activated, which shortens the electric telescopic rod 14 and drives the lifting frame 11 and rotating frame 12 to rise to a position where the bottom of the casting mold is slightly higher than the top of the insertion frame 7. Next, the third servo motor 13 is activated again to drive the rotating frame 12 to rotate, aligning the casting mold with the installation position of the insertion frame 7. Then, the electric adjusting rod 19 is activated, driving the lifting column rod 20 to rise along the lifting guide port 21 of the I-shaped mounting frame 16. Through the transmission rod 22, the cantilever frame 18 slides out along the triangular support frame 17, so that the casting mold on the cantilever frame 18 is directly above the insertion frame 7. Subsequently, the electric telescopic rod 14 extends, raising the lifting frame 11 and rotating frame 12 to a position where the bottom of the casting mold is slightly higher than the top of the insertion frame 7. As the height of the lowering frame 11 decreases, the casting mold on the cantilever frame 18 also decreases synchronously and is inserted into the insertion frame 7 below it. After the casting mold is smoothly placed into the insertion frame 7, the cantilever frame 18 slides back relative to the corresponding triangular support frame 17 by activating the electric adjusting rod 19. During this process, the cantilever frame 18 also extends relative to the hook strip 33. After the cantilever frame 18 is completely separated from the hook strip 33, the height of the cantilever frame 18 is further reduced by activating the electric telescopic rod 14 until the cantilever frame 18 falls back to its original position within the underground frame 2. Since the rotating frame 12 will make vertical contact with the contact ring 29 when it rises, the rising frame 12 will push the lifting ring frame 27 through the contact ring 29 to form a lifting ring. The lifting ring frame 27 opens the annular space between the support frame 3 and the inner support protective frame 23. When the rotating frame 12 falls, the lifting ring frame 27 falls back to its original position, closing the annular space between the support frame 3 and the inner support protective frame 23. This, together with the sheet metal protective plate 24, forms a fully enclosed protective space to prevent material splashing during centrifugation. Due to the setting of the limiting protrusion 40, when the limiting frame 30 is placed on the suspension frame 18 via the hook strip 33, the limiting protrusion 40 can limit the falling limit of the first half mold 31 and the second half mold 32 relative to the limiting frame 30, allowing the first half mold 31 and the second half mold 32 to be lifted synchronously with the lifting of the limiting frame 30. In this state, the closing plate 34 will close the two semi-circular holes 35.When the limiting frame 30 is inserted into the support frame 3, and the lifting effect of the cantilever frame 18 on the hook strip 33 fails, the limiting frame 30, under its own weight, falls relative to the first half mold 31 and the second half mold 32. The closing plate 34 falls synchronously with the limiting frame 30, causing the overlapping opening on the closing plate 34 to coincide with the semi-circular hole 35. This allows the semi-circular hole 35 to connect with the material passage hole 10 through the overlapping opening. When the limiting frame 30 is lifted again, the closing plate 34 will close the semi-circular hole 35 again.

[0029] After the casting mold is placed relative to the insertion frame 7, the external concrete pump is started, and the mixed concrete is pumped into the elbow pipe 39 through the guide pipe 38, and then distributed to each branch pipe 8 through the delivery pipe 4. With the sealing effect of the sealing ring 9, the concrete is injected into the casting mold through the material outlet 10. During the casting process, the first servo motor 5 is started, driving the support frame 3 to rotate the casting mold at a uniform speed. The centrifugal speed and centrifugation time are adjusted according to the specifications of the precast parts. The centrifugal speed is usually 50 r / min to 200 r / min, and the centrifugation time is usually 10 minutes to 30 minutes. Under the action of centrifugal force, the concrete is squeezed against the inner wall of the casting mold to achieve compaction and reduce internal porosity. At the same time, the free water inside the concrete is released through the seepage hole 36 and then discharged through the opening of the insertion frame 7. The water droplet 37 falls into the protective structure, achieving centralized recovery of free water. During centrifugation, the load and speed of the first servo motor 5 are monitored in real time. The operating parameters are adjusted based on the feedback data from the force sensor inside the first servo motor 5 to ensure process stability. During the casting process, the pre-set casting mold is re-inserted into the cantilever frame 18. The casting mold is still installed one at a time. After the cantilever frame 18 has completed one cycle of insertion, the casting mold on the cantilever frame 18 is raised by the operation of the electric adjusting rod 19. When the cantilever frame 18 without a casting mold is raised to the height corresponding to the casting mold in the insertion frame 7, the corresponding height allows the hook strip 33 of the cantilever frame 18 to easily hook the casting mold in the insertion frame 7 without interfering with the insertion frame 7. Afterwards, the cantilever frame 18 is brought to a high-stop state, and the corresponding electric adjusting rod 19 is used to push the cantilever frame 18 into the insertion frame 7. When the cantilever frame 18 is hooked into the hook strip 33 on the insertion frame 7, the electric telescopic rod 14 is used to raise the cantilever frame 18 to lift and pull out the casting mold inside the cantilever frame 18. After the casting mold is completely removed from the insertion frame 7, the electric adjusting rod 19 is used again to slide the extended cantilever frame 18 back into place relative to the triangular support frame 17. During this process, the casting mold to be cast is first pushed into the top of the insertion frame 7. After the cantilever frame 18 containing the casting mold is completely retracted into the corresponding triangular support frame 17, the cantilever frame 18 is then pulled back into place. The casting mold is positioned directly above the insertion frame 7. Then, multiple cantilever frames 18 are simultaneously lowered in height, allowing the casting mold to be inserted into the corresponding insertion frame 7. Next, the cantilever frames 18 above the insertion frame 7 are pulled away from it. Then, the third servo motor 13 is gradually decelerated until the cantilever frames 18 stop rotating. The height of the cantilever frames 18 is then lowered, causing them to fall back into the underground frame 2. Afterward, the completed casting mold can be removed and unloaded. Once removed from the cantilever frames 18, the casting mold to be cast is reinstalled. The casting mold re-inserted into the insertion frame 7 will then undergo centrifugal casting again. This process is repeated to achieve continuous casting of precast building components.

[0030] During the process of the casting mold being pulled out relative to the insertion frame 7, the sealing plate 34 covers and seals the semi-circular hole 35 to prevent the concrete poured into the casting mold from flowing out again. The second servo motor 6 drives the rotation of the conveying pipe 4, thereby enabling the switching and connection of the diversion pipe 8 with different material passage holes 10. Furthermore, due to the sealing ring 9, when the diversion pipe 8 and the material passage hole 10 are misaligned, the sealing ring 9 can block and seal the material passage hole 10. During the centrifugal casting stage, centrifugal force achieves compaction and water expulsion of the concrete, improving the precast component forming quality and curing rate. The free water collected during centrifugation flows along the conical ring plate 28. The material is diverted to the recycling sheet metal pool 25 and then transported to the designated recycling container through the external feed pipe 26. After secondary treatment, it can be reused in the casting operation, reducing material waste and environmental pollution. After the centrifugal operation, the recycling system should be kept running for 5 to 10 minutes to ensure the recovery of residual free water in the protective structure. After a batch of precast components is cast, the concrete pump and loading / unloading system are stopped, and the main power supply is disconnected to ensure that the equipment is completely powered off. The residual concrete inside the automated casting line for energy-saving precast building components is cleaned, and the debris attached to the surface of the support frame 3, insertion frame 7, and material passage hole 10 is cleaned. The operating parameters and equipment status are recorded to form an operation log. After the casting mold is completed, it should be demolded after the concrete has cured. During the demolding process, only the first half mold 31 and the second half mold 32 need to be pulled out relative to the limiting frame 30, and the relatively fitted first half mold 31 and the second half mold 32 need to be separated to achieve demolding of the precast building component after curing. The centrifugal casting process adopted by the automated casting conveyor line for energy-saving precast building components is not only the key to improving the quality of precast components, but also the core process adapted to the production of energy-saving precast building components. During the casting process, the centrifugal force generated by the first servo motor 5 driving the bearing frame 3 to rotate the casting mold at a uniform speed can not only play an auxiliary role in compacting the cast concrete, but also effectively reduce the mixing of concrete. The internal pores of concrete enhance the density and structural strength of precast components, thereby reducing energy consumption and maintenance costs during the later use of energy-saving precast components. This aligns with the core requirement of "long-term energy saving" in energy-saving precast components. It also accelerates the release of free water from the concrete, significantly increasing the curing rate of precast components, shortening the production cycle, and reducing energy consumption during production. In conjunction with a protective recycling structure, the released free water is directed and collected, and after secondary treatment, it can be reused in concrete pouring operations, realizing the recycling of water resources, reducing water waste, and practicing the "environmentally friendly and energy-saving" production concept of energy-saving precast component production.

[0031] Furthermore, the "one-on-one" filling method enables continuous pouring operations, reducing energy waste caused by equipment idleness, improving production efficiency, and further reducing energy consumption per unit of precast component. The reuse of molds also reduces energy consumption and environmental pollution during mold processing, aligning with the "low-carbon and environmentally friendly" production orientation of energy-saving precast building components. In addition, the coordinated design of the conveying pipe 4, the diversion pipe 8, and the sealing ring 9 in the equipment enables precise concrete delivery, reducing leakage losses during concrete delivery, improving material utilization, and avoiding increased energy consumption due to material waste. Simultaneously, the controllable drive of the second servo motor 6 on the conveying pipe 4 allows for precise docking and switching between the diversion pipe 8 and the material passage hole 10, supplying concrete on demand and reducing waste caused by excessive concrete delivery and subsequent cleaning energy consumption. The rational layout of the above-ground frame 1 and the underground frame 2 not only optimizes the space occupied by the equipment but also reduces vibration losses and energy consumption during equipment operation, comprehensively ensuring "low consumption, high efficiency, and environmental protection" in the production process of energy-saving precast building components, truly realizing energy conservation. The concept of energy conservation is integrated throughout the entire process of precast component casting, transportation, and molding, facilitating the large-scale production of high-quality, low-energy-consumption precast building components. For energy-saving concrete material formulations, multiple options can be selected based on specific application needs. The following is a specific example of an energy-saving concrete material formulation: 300 kg / m³ cement, 80 kg / m³ grade I fly ash, 70 kg / m³ slag powder, 780 kg / m³ medium sand, 1150 kg / m³ 5-25 mm crushed stone, and 4.5 kg / m³ polycarboxylate superplasticizer. With 160 kg / m³ of clean water, this formula replaces part of the cement by adding industrial waste such as fly ash and slag powder, effectively reducing the high energy consumption and carbon emissions in the cement production process, which aligns with the concept of energy conservation. At the same time, the polycarboxylate superplasticizer can significantly reduce the water-cement ratio. Combined with the centrifugal casting process, it can further improve the density of concrete, reduce the energy consumption and loss in the later stage, and reduce the amount of free water released, thereby reducing the cost of recycling and treatment. This allows the concept of energy conservation to run through the entire process of precast component production from the source of materials, truly realizing the green and efficient production of energy-saving precast building components.
