When the roller 82 moves to the intersection of the first rail 21 and the second rail 22, the roller 82 needs to move from the first rail 21 to the second rail 22; opening the first hydraulic cylinder 83 to enable the first hydraulic cylinder 83 to be in contact with the ground to provide support for the die table 1, opening the second hydraulic cylinder 85 to enable the second hydraulic cylinder 85 to drive the support 81 and the roller 82 to move upwards, enabling the roller 82 to be located above the sliding rail 2, opening the second variable frequency motor 86 to enable the second hydraulic cylinder 82, the support 81, the roller 82 and the first variable frequency motor 84 to rotate 90 degrees to enable the roller 82 to be aligned with the second guide rail 22, opening the second hydraulic cylinder 85 to enable the support 81 and the roller 82 to move downwards, enabling the roller 82 to collide with the inside of the second guide rail 22, opening the first hydraulic cylinder 83 to enable the first hydraulic cylinder 83 to shrink upwards, and opening the first variable frequency motor 84 to enable the roller 82 to move along the second guide rail 22; similarly, when the roller 82 needs to move from the second rail 22 to the first rail 21. Placing the poured concrete into an idle standing area in sequence, and standing the concrete for 5 hours. When the prefabricated member is steamed in the steam curing chamber 63 for 4 hours, the lifting door 61 between the steam curing chamber 63 and the cooling chamber 66 is opened, the first variable frequency motor 84 is opened, so that the die table 1 in the steam curing chamber 63 enters the cooling chamber, meanwhile, steam in the steam curing chamber 63 enters the cooling chamber 66 together, the temperature of the prefabricated member entering the cooling chamber 66 is prevented from being too low, the lifting door 61 is closed, the lifting door 61 between the standing chamber 61 and the steam curing chamber 63 is opened, the die table in the standing chamber 61 is moved into the steam curing chamber 63, the die table 1 and the prefabricated member enter the standing chamber 62 after standing for 4 hours in the standing area, and all the lifting doors 1 are closed; the fan 42 is turned on to enable air to quickly enter the air spraying pipe 43, the air penetrates through the fixed shaft 47 and the fan blades 44 to be sprayed out of the first spray nozzle 46, the air sprayed out of the first spray nozzle 46 is perpendicular to the fan blades 44, so that the fan blades 44 and the fixed shaft 47 are driven to rotate, the fan blades 44 blow the air to move towards the cooling pipe 41, the air is heated in the cooling chamber 66, the air takes away heat in the cooling chamber 66 and enters the static chamber 62, and the hot air is continuously contacted with concrete members in the static chamber 62, so that the concrete drying efficiency is accelerated; after 2 hours, opening the lifting door 61 at one end of the cooling chamber 66 to expose the die table 1 and the prefabricated member to the air, and sliding the die table 1 and the prefabricated member out of the cooling chamber 66; when the lifting door 61 at one end of the cooling chamber 66 moves upwards, the saw teeth 74 are driven to move upwards to push the gears 71 to rotate, the two gears 71 rotate to change the moving direction, so that the rack 73 and the mounting rod 72 are driven to move upwards, the mounting rod 72 drives the piston 48 to move inside the fixed pipe 45 to seal the cooling pipe 41, and the mounting rod 72 drives the lifting pipe 52 to move upwards to be separated from the fixed plug 57; after the prefabricated member is steamed in the steam curing chamber 63 for two hours, steam is continuously accumulated in the steam curing chamber 63, the fixing plug 57 presses the rubber rod 56 upwards along with the gradual increase of the pressure in the communicating pipe 53 during the steam, the fixing plug 57 presses the rubber rod 56 to ensure that the rubber rod 56 is deformed to an increasing degree, when the pressure reaches a certain amount, the fixing plug 57 slides from the side wall of the rubber rod 56, and at the moment, the fixing plug 57 passes through the restraint of the rubber rod 56, the rubber rod 56 is reset, the fixing plug 57 is accelerated to compress the spring 59, the magnetic ring 55 on the side wall of the fixing plug 57 adsorbs the metal rod 58 when the fixing plug 57 moves upwards, the fixing plug 57 is fixed on the side wall of the metal rod 58, and meanwhile, the fixing plug 57 moves to open the communicating pipe 53, so that the steam in the steam curing chamber 63 penetrates through the communicating pipe 53 and the mounting pipe 51 to enter the inside of the standing chamber 62, and the prefabricated member in the standing chamber 62 is preheated; when the pressure of the steam inside the steam curing chamber 63 is reduced after a part of steam is discharged, the pressure of the spring 59 to the fixed plug 57 is larger than the resistance of the downward movement of the fixed plug 57, so that the fixed plug 57 drives the magnetic ring 55 to move and break away from the metal rod 58, the spring 59 drives the fixed plug 57 to accelerate downward movement, so that the hemispherical fixed plug 57 slides through the side wall of the rubber rod 56, and the rubber rod 56 props against the fixed plug 57 to fix the fixed plug 57; as the steam is condensed, steam inside the steam curing chamber 63 is allowed to enter the interior of the standing chamber 62 at intervals, and the preform is preheated for 2 hours. When the mold table 1 slides out from the cooling chamber 66, the servo motor 9 is turned on to open the mold plate above the mold table 1, leak the prefabricated member in the mold plate, and stretch the prefabricated member. The driving mechanism 8 is opened, the die table 1 moves to a hoisting area with the prefabricated member, the prefabricated member is hoisted and stored on the surface of the die table 1 by using the crane, the surface of the die table 1 is cleaned, the above operation is repeated, the die table 1 is recycled, the prefabricated member is produced in a pipelining mode, and the production efficiency of people is increased.
