A prefabricated reinforced concrete slab staircase, this device design is suitable for prefabricated staircase installation operations in the construction industry, the upper and lower damping beams are installed in a built-in manner and have a certain damping function, the setting of the transverse traction hole and the lateral traction hole ensures the traction efficiency, and the upper and lower casting frames improve the consistency of the overall structure of the prefabricated staircase frame through the pouring port architectural concrete.

[0004] During the production process of prefabricated stairs, concrete is needed to be used to cast the mold so as to realize the forming of the prefabricated stairs. After the concrete is prepared by the workers, it is generally stored in a storage barrel. However, when concrete is needed for pouring, the staff generally needs to pour the concrete from the storage barrel into a cart and then push it to the pouring site. In this process, due to the large amount of concrete stored in the storage barrel, the storage barrel is heavy and very inconvenient to move. In addition, waste and pollution are easily caused in the process of pouring concrete. In addition, due to the fluidity of concrete, workers often find it difficult to control the amount when pouring, which makes it difficult to accurately control the amount of concrete during pouring, thus affecting the quality and construction efficiency of the prefabricated stairs. Summary of the invention

[0005] The purpose of the present invention is to provide a concrete distribution and storage device for pouring prefabricated stairs, so as to solve the problems in the prior art that a large amount of concrete is stored in the storage bucket, resulting in the storage bucket being heavy and very inconvenient to move, and easily causing waste and pollution in the process of pouring out the concrete. In addition, due to the fluidity of the concrete, workers often find it difficult to control the amount when pouring it, resulting in the difficulty in accurately controlling the amount of concrete during pouring, which in turn affects the quality and construction efficiency of the prefabricated stairs.

[0006] To achieve the above object, the present invention provides the following technical solution: a concrete material distribution storage device for pouring prefabricated stairs, comprising a bottom plate, a top rear side of the bottom plate is fixedly connected to a material discharge mechanism, and a top front side of the bottom plate is fixedly connected to a material discharge platform;

[0007] The unloading platform includes a unloading platform main body, a control frame is arranged on the rear side of the unloading platform main body, and the left and right sides of the front side of the unloading platform main body are respectively movably connected with fixing mechanisms. By accurately controlling the movement of the frame, the synchronous movement of the fixing mechanism can be achieved. This mechanism ensures the coordination and consistency of the two parts, thereby improving the efficiency and stability of the overall system. In this way, the fixing mechanism can achieve precise synchronous movement under the drive of the frame, ensuring the smooth operation of the entire mechanical system.

[0008] Preferably, the unloading platform body includes a cart placement platform, and the rear sides of the left and right sides of the cart placement platform are respectively fixedly connected with connecting vertical plates, and the rear sides of the two connecting vertical plates are fixedly connected with slide plates. The original intention of designing the cart placement platform is to place the cart safely and firmly in a specific position, so that workers will be more convenient and efficient when operating and moving the cart.

[0009] Preferably, the control frame includes a hydraulic push rod, the front side of the hydraulic push rod is fixedly connected to the rear side of the trolley placement platform, the top of the trolley placement platform is fixedly connected to a rotating rod push-pull block, the left and right sides of the front side of the rotating rod push-pull block are respectively rotatably connected to push-pull rotating rods, and the two push-pull rotating rods are rotatably connected to an L-shaped push-pull plate on one side away from the rotating rod push-pull block. Through the precise pushing and pulling action of the hydraulic push rod, effective control of the push-pull rotating rod can be achieved, and the push-pull rotating rod and the rotating rod push-pull block are closely matched and act on the L-shaped push-pull plate together. When the hydraulic push rod applies thrust, the push-pull rotating rod will rotate accordingly, and then push the rotating rod push-pull block to apply a push-pull force to the L-shaped push-pull plate. The action of this push-pull force enables the two L-shaped push-pull plates to move flexibly. Specifically, this movement can be a contraction action to the inside or an expansion action to the outside.

[0010] Preferably, the front sides of the two L-shaped push-pull plates are slidably connected to the left and right sides of the rear side of the slide plate respectively, the outer sides of the two L-shaped push-pull plates are fixedly connected to push-pull cross bars, the front sides of the inner sides of the two L-shaped push-pull plates are fixedly connected to arc-shaped push-pull rods, the tops and bottoms of the front sides of the two arc-shaped push-pull rods are rotatably connected to rotating block rotating rods, the two groups of rotating block rotating rods on the rear sides away from the arc-shaped push-pull rods are rotatably connected to rotating blocks, the two outer groups of rotating blocks on the sides away from the rotating block rotating rods are rotatably connected to connecting plates, and the two groups of connecting plates The rear sides are respectively fixedly connected to the top and bottom of the two connecting vertical plates, and the front sides of the two groups of connecting plates are fixedly connected to the limited sliding groove blocks on one side away from the rotating block rotating rod. When the L-shaped push-pull plate moves inward or outward, it will drive the two push-pull cross bars to move along the same trajectory. This coordinated movement mechanism enables the arc-shaped push-pull rod to exert force on the rotating block rotating rod, thereby prompting the rotating plate to rotate. Through this ingenious design, the linkage effect between the various components is realized, ensuring the smooth operation of the entire mechanical system.

[0011] Preferably, the rear sides of the inner sides of the two push-pull cross bars are fixedly connected with connecting blocks, and the two connecting blocks are rotatably connected with rotating rods on the sides of the outer walls away from the push-pull cross bars. The outer walls of the two rotating rods on the sides away from the connecting blocks are rotatably connected with push-pull blocks, and the inner sides of the two rotating rods are fixedly connected with springs. The two rotating blocks can be driven to move along a specific trajectory through the movement of the two push-pull cross bars. This movement method allows the rotating rod to rotate and then change the angle, so that the push-pull block can be lifted and lowered. In this process, the spring plays a vital role. The spring exists to provide a stable rebound force when the two rotating rods rotate, ensuring that the push-pull block can be lifted and lowered smoothly.

[0012] The two wheels are fixedly connected to each other with a plurality of movable plates, and the two movable plates are connected to each other with a plurality of movable plates at a rear end.

[0015] Preferably, the opposite ends of the two rotating rods are rotatably connected with a rotating plate, the front side of the rotating plate is fixedly connected with a lower material bin, the front sides of the left and right sides of the lower material bin are respectively fixedly connected with sliding blocks, the inner walls of the two sliding blocks are slidably connected with a second sliding rod, the bottom ends of the two second sliding rods are respectively fixedly connected to the left and right sides of the front side of the top of the bottom connecting plate, the outer walls of the two second sliding rods are respectively covered with a second spring, the top ends of the two second springs are respectively fixedly connected to the bottoms of the two sliding blocks, the bottom of the rotating plate is slidably connected to the top of the push-pull block, and the rotation of the rotating rod drives the rotating plate to rotate at a corresponding angle, so that the lower material bin can be tilted as needed to facilitate the smooth outflow of concrete.

[0016] Preferably, a baffle is fixedly connected to the rear side of the inner wall of the lower material bin, the top of the baffle is in contact with the bottom end of the material storage barrel, and a discharge port is fixedly connected to the front side of the lower material bin, and the bottom end of the material storage barrel can be effectively blocked by the setting of the baffle.

When pouring prefabricated stairs, the trolley is placed between the two fixed plates on the top of the placement platform, and the hydraulic push rod is started to drive the rotating rod to rotate.

[0019] 2. This application is provided with a material unloading platform and a material unloading mechanism, so that the concrete dispensing process is more stable and controllable. The coordinated use of the hydraulic push rod and the rotating rod push-pull block on the control frame can realize the fine adjustment of the concrete outflow, ensuring that the amount of concrete poured each time meets the design requirements. The specific push-pull block moves up, and the rotating plate rotates up accordingly, and the unloading bin is close to the material passing funnel.

After the material is taken, the hydraulic push rod operates in the opposite direction, the push-pull block moves down, the rotating plate rotates down, the unloading bin returns to its position, and the baffle re-blocks the bottom of the storage barrel.

The two outer groups of rotating blocks 228 are rotatably connected to the connecting plates 229 on one side away from the rotating block rotating rod 227. The rear sides of the two groups of connecting plates 229 are respectively fixedly connected to the top and bottom of the two connecting vertical plates 212.

[0034] When the prefabricated stairs need to be cast, the staff pushes the trolley to the top of the trolley placement platform 211 between the two fixed plates 231, and then starts the hydraulic push rod 221, which pulls the rotating rod push-pull block 222, thereby driving the push-pull rotating rod 223 to rotate. As the push-pull rotating rod 223 rotates, the L-shaped push-pull plate 224 slides along the slide plate 213, pulling the push-pull cross bar 225 and the arc-shaped push-pull rod 226 to move accordingly, and the movement of the arc-shaped push-pull rod 226 drives the rotating block rotating rod 2 27 rotates, and then the inner rotating block 228 rotates along the guidance of the connecting plate 229, and finally the fixed plate 231 is pushed by the outer rotating block 228, and the sliding rod 233 in the fixing mechanism 23 slides under the guidance of the limiting slide block 2211, so that the fixed plate 231 can be adjusted according to the needs, and the appropriate limiting clamp 234 is driven to fix the material-taking cart, so that the material-taking cart is fixed on the cart placement platform 211, ensuring that the cart will not move during the concrete taking process;

[0035] When the two push-pull cross bars 225 move inward, the two rotating bars 2213 rotate and change their angles, thereby pushing the push-pull block 2214 to move upward.

The cam 314 is a kind of hollow structure, and the cam 314 is a kind of hollow structure. The cam 314 is a kind of hollow structure, and the cam 314 is a kind of hollow structure. The cam 314 is a kind of hollow structure, and the cam 314 is a kind of hollow structure.

[0037] When the push-pull block 2214 moves upward, the rotating plate 310 rotates upward accordingly, so that the lower bin 311 gradually approaches the opening of the material funnel 38. As the rotating plate 310 rotates, the baffle 312 moves away from the discharge port at the bottom of the storage barrel 34, and the storage barrel 34 begins to discharge into the lower bin 311. The concrete in the lower bin 311 gradually tilts toward the discharge port 313. Due to gravity, the concrete begins to flow out of the discharge port 313 and falls into the container formed by the two fixed plates 23 through the material funnel 38. 1 is fixed in the trolley for taking materials. At the same time, the second slide bar 315 maintains close contact with the slider 314 under the action of the second spring 316, ensuring that the rotating plate 310 can rotate smoothly during the material unloading process. When the material unloading is completed, the staff can reverse the operation of the hydraulic push rod 221 to make the push-pull block 2214 move downward, and the rotating plate 310 rotates downward accordingly, the unloading bin 311 returns to the parallel position, and the baffle 312 blocks the bottom end of the storage barrel 34 again.

[0038] Working principle: When the prefabricated stairs need to be cast, the staff pushes the trolley to the top of the trolley placement platform 211 between the two fixed plates 231, and then starts the hydraulic push rod 221, which pulls the rotating rod push-pull block 222, thereby driving the push-pull rotating rod 223 to rotate. As the push-pull rotating rod 223 rotates, the L-shaped push-pull plate 224 slides along the slide plate 213, pulling the push-pull cross bar 225 and the arc-shaped push-pull rod 226 to move accordingly. The movement of the arc-shaped push-pull rod 226 drives the rotating block rotating rod 227 to rotate, thereby causing the inner rotating block 228 to rotate along the connecting plate 229. The guide rotates, and finally the fixed plate 231 is pushed by the outer rotating block 228. The sliding rod 233 in the fixing mechanism 23 slides under the guidance of the limiting slide block 2211, so that the fixed plate 231 can be adjusted according to the needs, and drives the appropriate limiting clamp 234 to fix the material-taking cart, thereby fixing the material-taking cart on the cart placement table 211 to ensure that the cart will not move during the concrete taking process. When the two push-pull cross bars 225 move inward, the two rotating rods 2213 rotate and change the angle, thereby pushing the push-pull block 2214 to move upward;

[0039] When the push-pull block 2214 moves upward, the rotating plate 310 rotates upward accordingly, so that the lower bin 311 gradually approaches the opening of the material funnel 38. As the rotating plate 310 rotates, the baffle 312 moves away from the hollow portion at the bottom of the storage barrel 34, and the storage barrel 34 begins to discharge materials into the lower bin 311. The concrete in the lower bin 311 gradually tilts toward the discharge port 313. Due to gravity, the concrete begins to flow out of the discharge port 313 and falls into the material funnel 38 formed by the two fixed plates 23. 1 is fixed in the trolley for taking materials. At the same time, the second slide bar 315 maintains close contact with the slider 314 under the action of the second spring 316, ensuring that the rotating plate 310 can rotate smoothly during the material unloading process. When the material unloading is completed, the staff can reverse the operation of the hydraulic push rod 221 to make the push-pull block 2214 move downward, and the rotating plate 310 rotates downward accordingly, the unloading bin 311 returns to the parallel position, and the baffle 312 blocks the bottom end of the storage barrel 34 again.
