DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Embodiment:

[0028] The application discloses a prefabricated component initial maintenance rapid flow transfer system, which comprises a pre-maintenance kiln 1, a steam curing kiln 4, a flow transfer track 5 and a transfer trolley 6; the flow transfer track 5 is arranged at the bottom of the pre-maintenance kiln 1 and the steam curing kiln 4, the transfer trolley 6 is arranged on the flow transfer track 5, and the transfer trolley 6 is used for transferring prefabricated components; at least a plurality of transfer trolleys 6 are arranged on the flow transfer track 5, at least one of the transfer trolleys 6 is used for carrying prefabricated components to be steam cured, at least one of the transfer trolleys 6 is used for transferring prefabricated components into the pre-maintenance kiln 1, at least one of the transfer trolleys 6 is used for transferring prefabricated components into the steam curing kiln 4, and at least one of the transfer trolleys 6 is used for carrying prefabricated components after steam curing.

[0029] The pre-curing kiln 1 is used for pre-curing of the concrete prefabricated components. Before the formal implementation of the curing period, the concrete prefabricated components need to be pre-cured in the pre-curing kiln 1 for a certain period of time. For pre-curing nodes, it can ensure that the prefabricated concrete components obtain an initial strength and can resist the destructive force generated by the later heating. With the increase of the pre-curing period, the initial strength of the pre-cured concrete components is enhanced. The curing kiln 4 is used for curing of the concrete prefabricated components. The concrete prefabricated components undergoes heating, constant temperature and cooling stages in the curing kiln 4. After the formal curing, the structural strength of the prefabricated components is enhanced. The pre-curing kiln 1 and the curing kiln 4 are connected by the transfer track 5. In the process of transfer, the prefabricated components can be directly transferred from the pre-curing kiln 1 to the curing kiln 4 by the transfer car 6. At the same time, new prefabricated components can also be synchronized into the pre-curing kiln 1, and the prefabricated components after curing can also be synchronized out of the curing kiln 4. Through this design, the transfer efficiency of the concrete prefabricated components during the curing process is significantly improved, the curing efficiency of the concrete prefabricated components is improved, the curing time is reduced, and the energy consumption is reduced. In addition, through this design, it is also convenient to control the independent kiln temperature. By reducing the temperature of the curing kiln 2 and using an early strength concrete material that can adapt to low curing temperature or normal temperature, we can efficiently produce shield concrete segments. This technical innovation not only effectively solves the high energy consumption problem in the segment curing process, but also greatly improves the turnover rate of the mold and shortens the production cycle. This ultimately improves the technical level of large prefabricated components. The independent setting of the pre-curing kiln 1 and the curing kiln 2 makes the production process more flexible, and the maintenance temperature of each can be adjusted according to different needs. This flexibility not only improves production efficiency, but also meets the performance requirements of various concrete materials. By reducing the temperature of the curing kiln 2, the energy consumption required during the curing process can be effectively reduced. This not only reduces production costs, but also meets the current trend of environmental protection and energy saving, reducing the impact on the environment. Through this design, the use of early strength concrete that can adapt to low curing temperature or normal temperature not only shortens the curing time of concrete, but also improves the efficiency of construction. The application of this material can ensure that sufficient strength is achieved in a relatively short period of time, thereby speeding up the subsequent construction progress. The reduced curing temperature and shortened production cycle enable the mold to be reused more quickly. This not only reduces the idle time of the mold, but also reduces the loss of the mold, thereby reducing the overall production cost

[0030] In a preferred embodiment, the front side of the pre-curing kiln 1 and the pre-curing kiln 4 are provided with mounting frames 8; the mounting frames 8 are rotatably connected with adjusting lead screws 12, the adjusting lead screws 12 are connected with driving devices, and the driving devices are used to drive the adjusting lead screws 12 to rotate; the pre-curing kiln 1 and the pre-curing kiln 4 are slidably connected with kiln doors 11, the two sides of the kiln doors 11 are fixedly connected with mounting blocks 13, and the mounting blocks 13 are threadedly connected with the adjusting lead screws 12 on the two sides. In order to facilitate the sealing of the pre-curing kiln 1 and the pre-curing kiln 4, the two sides of the kiln doors 11 are provided with mounting frames 8, and the adjusting lead screws 12 on the mounting frames 8 are mainly used to control the opening and closing of the kiln doors 11. The driving devices drive the lead screws to rotate, the adjusting lead screws 12 drive the mounting blocks 13 to move, and the mounting blocks 13 drive the kiln doors 11 to move. Through this design, the kiln doors 11 can be conveniently controlled, and the accidental opening of the kiln doors 11 to cause chaos in the entire flow system is effectively prevented.

[0031] In a preferred embodiment, the pre-curing kiln 1 comprises a first steel frame structure 9 and a first stainless steel skin 10; the pre-curing kiln 4 comprises a second steel frame structure 2 and a second stainless steel skin 3; the first stainless steel skin 10 is arranged on the first steel frame structure 9, and the second stainless steel skin 3 is arranged on the second steel frame structure 2. Further optimization is that the inner side of the first stainless steel skin 10 is provided with a first heat insulation layer, and the inner side of the second stainless steel skin 3 is provided with a second heat insulation layer. The pre-curing kiln 1 and the pre-curing kiln 4 composed of the steel frame structure and the stainless steel skin have high overall strength, can effectively prevent deformation caused by temperature difference, and ensure the performance stability of the pre-curing kiln 1 and the pre-curing kiln 4 during long-time operation. The arrangement of the first heat insulation layer and the second heat insulation layer can effectively reduce the loss of heat, so that the temperature of the pre-curing kiln 1 in the initial curing stage and the temperature of the pre-curing kiln 4 in the curing process are more stable. This helps to maintain the appropriate temperature required in the curing process, improves the hardening speed and strength of the concrete member, and reduces energy consumption.

Further optimally, the inside of the kiln door 11 is provided with a door body thermal insulation layer. The provision of the sealing structure 14 can effectively block the heat exchange between the kiln door 11 and the outside, reducing the heat loss during maintenance. This not only helps to maintain the temperature stability inside the pre-curing kiln 1 and the steaming kiln 4, but also helps to reduce energy consumption, reduce unnecessary heat supplement, and thus improve overall energy efficiency. The sealing strip or sealing gasket can tightly fit between the kiln door 11 and the kiln body, preventing the leakage of steam and hot air, which is crucial for thermal insulation and maintenance environment. Good airtightness ensures sufficient steam circulation in the kiln, which helps to evenly steam the concrete components. The door body thermal insulation layer on the inside of the kiln door 11 can further improve the thermal insulation performance of the kiln door 11, maintaining the heat of the high-temperature environment inside, thereby ensuring the concentration and uniform distribution of heat during the steaming process. This can further improve the accelerated hardening effect of the concrete components and shorten the curing period. The door body thermal insulation layer can be made of materials such as rock wool, glass wool, and expanded perlite.

[0033] In a preferred embodiment, the driving device is an electric motor or a motor. As a driving device, the electric motor or the motor can provide continuous and stable power, enabling the adjustment screw rod 12 to operate smoothly. Stable power output ensures that the kiln door 11 can be smoothly opened or closed, preventing shaking or jamming during lifting, thereby improving the reliability and safety of the equipment.

[0034] In a preferred embodiment, the pre-curing kiln 1 is provided with a first steaming pipeline, and the steaming kiln 4 is provided with a second steaming pipeline. The first steaming pipeline in the pre-curing kiln 1 is mainly used to provide preliminary humidity and heat during the pre-curing stage to promote the initial moisture retention and hardening of the concrete components under lower temperature conditions. The second steaming pipeline in the steaming kiln 4 is responsible for providing higher temperature and steam flow during the steaming stage to accelerate the strength development of the concrete. This segmented management can make the maintenance in different stages more targeted, effectively improving the strength and durability of the concrete precast components.
