[0026] In this embodiment, the components of the device are electrically connected to an external control device through a conductive line, and the operating state of the device is controlled by the external control device. When the prefabricated stairs are produced, the operation of the hydraulic cylinder 104 and the extension of the piston rod can make the second template 5 move toward the side of the first template 4. Since the second template 5 is fixedly connected to the sliding seat 105, the sliding seat 105 can slide conveniently on the vertical channel steel of the base 101 through the moving wheel 106 provided at the bottom, so that the second template 5 is attached to the first template 4. At this time, the cavity between the first template 4 and the second template 5 can be used for pouring concrete, thereby realizing the production and use of prefabricated stairs. Since different buildings require stairs of different sizes, the prefabricated stairs During production, molds of different sizes are required for casting and molding, while the traditional mold size is fixed, and molds of multiple sizes are required to cast stairs of corresponding sizes, thereby increasing the purchase amount of molds. When the device is producing prefabricated stairs of different sizes, the corresponding first splicing template 8 or the second splicing template 9 can be lifted away by an external lifting device in the lifting ring 902. It should be noted that when lifting the first splicing template 8 or the second splicing template 9 at one end of the first template 4 or the second template 5, the lifting number of the first splicing template 8 and the second splicing template 9 on one side needs to be the same. When the corresponding number of first splicing templates 8 and second splicing templates 9 are lifted away, the first end 6 There will be a gap between the second end 7 and the first template 4 and the second template 5. By starting the servo motor 301, the gear 302 is engaged to transmit the first rack 303 and the second rack 304. Since the teeth of the first rack 303 and the second rack 304 face each other and are engaged with the gear 302, when the gear 302 is driven to rotate, the first rack 303 and the second rack 304 can be translated. Since the first rack 303 and the second rack 304 on the first template 4 and the second template 5 are respectively fixedly connected to the first end 6 and the second end 7 at both ends, and the first end 6 and the second end 7 are fixedly connected to one end of the plug-in rod 305, the first rack 303 and the second rack 304 are slidably plugged into the corresponding first plug-in slot 501, the plug-in rod 305 is slidably plugged into the corresponding second plug-in groove 502, so after removing the first splicing template 8 and the second splicing template 9, under the operation of the spacing adjustment mechanism 3, the first end head 6 and the second end head 7 at both ends of the first template 4 and the second template 5 can be adjusted to block the remaining spacing, so that there will be no leakage problem during concrete pouring, so that after the first splicing template 8 and the second splicing template 9 at both ends of the first template 4 and the second template 5 are completely removed, the spacing adjustment mechanism 3 adjusts the first end head 6 and the second end head 7 to fit tightly on the two ends of the first template 4 and the second template 5. At this time, since the first rack 303 and the second rack 304 are cross-staggered, they do not interfere with each other.The ends of the connecting rods 305 at both ends located inside the second connecting slots 502 will fit together without hindering the movement effect. By adjusting, the number of steps of the prefabricated staircase can be controlled, thereby firstly producing and using prefabricated staircases of different sizes, reducing the purchase of molds of different sizes, and improving practicality.
