Detailed implementation manners To more easily understand the structure of the present invention and the functional features and advantages that can be achieved, the following will describe the preferred embodiments of the present invention in detail in conjunction with the drawings as follows: Embodiment: Embodiment: As Figures 1 to 10 shown, the present invention provides a precast slab curing device, including: The movable frame 1 is movably arranged in the ground track 10, and a cross-hinged rod 2 is slidably arranged thereon; The lifting rod 3 is hinged to the middle of the cross rod at the lower end, and the upper end is hinged to the upper end of the movable frame 1 through a connecting rod 4; The main spray pipe 5 is arranged on the movable frame 1; The auxiliary spray pipe 6 is arranged on the lifting rod 3, and a plurality of nozzles are arranged thereon and on the main spray pipe 5; The driving mechanism 7 is arranged on one side of the movable frame 1 to drive the movable frame 1 to move and expand on the ground track 10 so as to adjust the distance between the main spray pipes 5 and the distance between the auxiliary spray pipe 6 and the main spray pipe 5.

[0018] It further includes a moving track 8 for conveying the concrete precast slab to move. The moving track 8 is arranged on the bottom surface and is located inside the movable frame 1. The moving track 8 is used to drive the concrete precast slab placed on the slab rack to slowly move into the movable frame 1 for spray curing.

[0019] See Figures 1 to 4 , the movable frame 1 includes a fixed beam 11 and a movable beam 12. The fixed beam 11 is fixedly arranged at one end of the ground track 10. There are multiple movable beams 12, and the multiple movable beams 12 slide in the ground track 10. The fixed beam 11 is used as the fixed point of the movable frame 1 through fixation. When the driving mechanism 7 works, it can drive the movable beam 12 to move on the ground track 10 to adjust the distance between the movable beams 12, so as to realize the adjustment of the spray area and distance of the main spray rod.

[0020] See Figure 2 , sliding limit grooves 13 are arranged at the lower ends on both sides of the movable frame 1. The upper end of the cross-hinged rod 2 is hinged to the upper end of the movable frame 1, and the lower end of the cross-hinged rod 2 is slidably arranged in the sliding limit groove 13 through a pulley 21. The pulley 21 can be replaced by a roller. During the process of the driving mechanism 7 driving the movable beam 12 to move, the synchronous movement and expansion of the multiple movable beams 12 are realized through the mutually hinged cross-hinged rod 2, so as to realize the expansion and storage of the movable frame 1.

[0021] See Figure 1 , rollers are arranged at the bottom of the movable beam 12, and the rollers are located in the ground track 10. When the driving mechanism 7 drives the movable beam 12 to move in the ground track 10, the rollers can be used for limiting, so that the movable beam 12 can move stably in the ground track 10.

[0022] The two sides and the top of the movable frame 1 are sleeved with a foldable and retractable waterproof cloth or waterproof cover to facilitate the formation of a closed spray space inside the movable frame 1.

[0023] As Figures 5 to 10As shown in the figure, as another embodiment of the present application, a first U-shaped member 91 and a second U-shaped member 92 are fixedly arranged at the upper end of the moving beam 12, and a third U-shaped member 93 is slidably arranged at the lower ends of the fixed beam 11 and the moving beam 12. The upper and lower ends of the cross-hinged rod 2 and the upper end of the connecting rod 4 are all hinged with an L-shaped rod 94, and the L-shaped rods 94 are respectively rotatably connected to the first U-shaped member 91, the second U-shaped member 92 and the third U-shaped member 93. By providing the first U-shaped member 91, the second U-shaped member 92 and the third U-shaped member 93, and relying on the L-shaped rods 94 rotatably connected at both ends, adjacent two cross-hinged rods 2 and the connecting rod 4 can be unfolded at a certain radian, so that the two rows of moving frames 1 can be unfolded to form a spray space in an arc structure, an L-shaped structure or an S-shaped structure, and different ground tracks 10 can be matched to realize spray spaces of different shapes, so as to adapt to the spray curing of concrete precast slabs with different structures. The first U-shaped member 91, the second U-shaped member 92 and the third U-shaped member 93 of the present application in combination with the L-shaped rod 94 can enable the two rows of moving beams 12 to swing in an arc to either side to form spray spaces of different structures. Further, the moving frame 1 of the present application can be used for spraying the concrete precast slab at the turning of the moving track 8, and in combination with the moving frame 1 arranged linearly, the spray curing of the concrete precast slab during the moving process can be realized, and it is applicable to the batch production of moving concrete precast slabs.

[0024] See Figure 9 , a rotating column 95 is rotatably arranged at the upper ends of the fixed beam 11, the moving beam 12 and the connecting rod 4, and the main spray rod and the auxiliary spray rod are fixedly arranged on the rotating column 95, so that when the two rows of moving frames 1 are unfolded into an arc structure, the main spray rod and the auxiliary spray rod can rotate and adapt according to their radian.

[0025] See Figure 6 , the ends of adjacent two cross-hinged rods 2 are hinged through a third U-shaped member 93, and the pulley 21 is connected to the third U-shaped member 93 at the lower part of the cross-hinged rod 2.

[0026] As another embodiment of the present application, as Figure 2 shown, the difference from the previous embodiment is that the ends of adjacent two cross-hinged rods 2 are hinged through a hinge shaft, and the pulley 21 is connected to the hinge shaft at the lower part of the cross-hinged rod 2. The moving frame 1 of this embodiment cannot turn and can only move linearly.

[0027] As another embodiment of the present application, as Figure 3As shown, the driving mechanism 7 includes a driving motor 71, a driving screw rod 72 and a slider 73. The driving motor 71 is fixedly arranged at the side end of the fixed beam 11. The slider 73 is fixedly arranged on the moving beam 12 at the front end of the fixed beam 11. The output end of the driving motor 71 is connected to the driving screw rod 72 through a coupling. The slider 73 is threadedly connected to the driving screw rod 72. The driving motor 71 drives the driving screw rod 72 to rotate through the coupling, so that the slider 73 threadedly connected to the driving screw rod 72 moves along its axial direction, thereby pushing the moving beam 12 to move, and relying on the cross-hinged rods 2 that are hinged to each other to realize the synchronous movement between multiple moving beams 12, thereby realizing the movement, unfolding and storage of the moving frame 1.

[0028] As another alternative to the driving mechanism 7, the driving mechanism 7 in this embodiment is an electric telescopic rod. The electric telescopic rod is arranged on the moving beam 12 at the front end of the fixed beam 11. The output end of the electric telescopic rod is hinged to the lower third U-shaped member 93 of the cross-hinged rod 2 or on the hinge shaft. The expansion and storage of the cross-hinged rod 2 are promoted through the telescopic movement of the electric telescopic rod to adjust the distance between the moving beams 12, thereby realizing the control of the distance and height adjustment between the main spray rod and the auxiliary spray rod.

[0029] The above is only the preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention or modify it into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the present invention.
