[0002] Reinforced concrete protective doors are a type of safety door commonly used in buildings or other structures. They are made of reinforced concrete, which is very strong and durable and can provide good compressive and tensile properties. They are usually used for firewalls, emergency exits, or areas that require additional protection. These doors are generally designed to withstand pressure and temperature under extreme conditions. The casting device for reinforced concrete protective doors usually refers to a concrete pouring device, which is responsible for transporting the concrete to the specific casting position to ensure that the concrete can be accurately injected into the required mold.
[0003] Publication No.: CN219910004U, a reinforced concrete casting device, includes a support frame and a mixing tank. The mixing tank is provided with a feed inlet at the top and a mixing mechanism for mixing the concrete inside. The two sides of the mixing tank are connected with oppositely distributed conveying pipes, and the conveying pipes are connected with a conveying pump. The bottom of the support frame is installed with rollers, and a translation mechanism is arranged inside. The translation mechanism is used to drive the ends of the two conveying pipes to move relatively; when the device is casting reinforced concrete, the ends of the conveying pipes can reciprocate relatively, increasing the casting range of the reinforced concrete, and there is no need for manual movement of the ends of the conveying pipes, saving manpower. In addition, the concrete inside the mixing tank can be stirred, effectively avoiding the solidification phenomenon of the concrete inside the mixing tank, and at the same time, the concrete on the inner wall of the mixing tank can be scraped off, avoiding the phenomenon of concrete adhering to the inner wall of the mixing tank.
[0004] In summary, when the casting device in the prior art CN219910004U is casting concrete, it cannot assist the staff in leveling the concrete poured into the mold, resulting in difficulty for the staff to judge the amount of concrete in the mold when observing the inside of the mold. Content of the Utility Model
[0005] The purpose of the utility model is to provide a casting device for reinforced concrete protective doors, which has the advantages of leveling the concrete inside the mold while casting the concrete into the mold, facilitating the staff to observe the height of the concrete inside the mold and judge the casting quantity, and solving the problem that the casting device cannot assist the staff in leveling the concrete poured into the mold when casting the concrete.
[0006] To achieve the above object, the utility model provides the following technical solution: a pouring device for a reinforced concrete protection door, including a bearing plate, clamping plates and a screw sleeve. On both sides of the top of the bearing plate, support plates are welded. In both of the support plates, a first bearing is embedded.

[0009] Preferably, a positioning sleeve is welded on the top of the screw sleeve. A positioning rod is welded on the opposite sides of the two support plates above the screw sleeve. The positioning rod passes through the positioning sleeve. The positioning rod limits the screw sleeve. When the screw sleeve moves horizontally on the lead screw, it moves on the positioning rod through the positioning sleeve, reducing the shaking of the screw sleeve.
[0010] Preferably, flanges are installed on the tops of both of the pouring pipes. A distance is left between the two flanges and the front and rear sides of the hydraulic cylinder. The two pouring pipes are respectively connected to the concrete conveying pipes through the flanges.
[0011] Preferably, movable rods are welded to the tops of the two scraping plates. The two connecting plates are each provided with a movable hole, and the tops of the two movable rods respectively pass through the two movable holes. The two movable rods limit the two scraping plates. When the two scraping plates move up and down or horizontally, the two movable rods move in the two movable holes, reducing the swaying of the two scraping plates.
[0012] Preferably, stoppers are installed at the tops of the two movable rods, and the outer diameters of the two stoppers are larger than the inner diameters of the two movable holes. The two stoppers prevent the two movable rods from slipping out of the two movable holes.
[0013] Preferably, handwheels are installed at the opposite ends of the two screws, and the opposite ends of the two screws are respectively fixedly connected to the inner rings of the two second bearings. The two handwheels can be used to rotate the two screws, and the two screws are movably connected to the two clamping plates through the two second bearings.
[0014] Preferably, fixing seats are installed at the bottom of the bearing plate in a rectangular array, and the fixing seats are perpendicular to the bottom of the bearing plate. The fixing seats provide a supporting force for the bearing plate.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] In the present utility model, by providing springs and scraping plates, the two scraping plates are movably connected to the two connecting plates through two groups of springs.
