Abstract
Description
Technical Field
[0001] This utility model belongs to the field of highway bridge prefabrication technology, and in particular relates to a concrete diversion and solidification device for prefabricated piles of highway bridges. Background Technology
[0002] Precast piles for highway bridges refer to piles that are prefabricated in a precast component processing plant, cured to the design strength, transported to the construction site, driven into the soil using a pile driver, and then the foundation beam (slab) is poured on top of the pile. The concrete grade used for precast piles for highway bridges should not be lower than 300#, and the diameter of the reinforcing steel bars in the piles should not be less than 12 mm. In order to resist hammering and penetrate the soil layer, the stirrups should be denser at the top and tip of the pile, and the main reinforcement at the pile tip should be bent up and welded to a mandrel. Reinforced concrete precast piles have the advantages of simple manufacturing, high strength, high rigidity, and the ability to be made into various cross-sectional shapes, and are a widely used pile type.
[0003] When producing precast piles in a factory, concrete is poured into a pile mold and allowed to solidify. Typically, a chute is used to guide the concrete into the mold. However, using a chute can easily cause separation between aggregates and fluids, resulting in unevenly composed concrete that affects the quality of the pile after molding. Severe separation can lead to segregation within the mold, rendering the concrete unusable and impacting pile production. Therefore, a concrete guiding and solidification device for highway bridge precast piles is needed. This device can agitate the aggregates and fluids in the chute, preventing segregation during concrete flow and ensuring effective solidification. Furthermore, the oscillating design of the discharge hopper improves the uniformity of concrete distribution during discharge, preventing concrete accumulation. Utility Model Content
[0004] The purpose of this invention is to provide a concrete diversion and solidification device for precast piles of highway bridges, which agitates the aggregate and fluid in the chute to prevent segregation of the concrete during diversion and thus ensures the solidification effect of the concrete. Furthermore, the oscillating setting of the discharge hopper can improve the uniformity of concrete distribution during discharge and prevent concrete accumulation, thereby solving the technical problems mentioned in the background art.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A concrete guiding and solidification device for precast piles of highway bridges, comprising a chute: a stirring rod is installed on the inner wall of the chute, the bottom of the stirring rod is connected to a feeding hopper, a guide hopper is provided on the surface of the feeding hopper, a T-shaped plate is fixedly connected to the surface of the feeding hopper, an electric telescopic rod is fixedly connected to the surface of the T-shaped plate by bolts, a turntable is provided on the surface of the T-shaped plate and a toothed plate is rotatably connected to it by a rotating shaft, a rack is fixedly connected to the output end of the electric telescopic rod by a flange, the rack meshes with the toothed plate, a pivot rod is welded to the surface of the turntable, a shaft is fixedly connected to the surface of the turntable, and the rear end of the shaft passes through the T-shaped plate and the guide hopper and is rotatably connected to the feeding hopper.
[0006] Preferably, a cover plate is bolted to the top of the chute.
[0007] Preferably, a sleeve block is slidably connected to the surface of the rack, and the sleeve block is fixedly connected to the T-shaped plate by bolts.
[0008] Preferably, the end of the lever extends into the inner cavity of the toothed plate, and a rotating sleeve is rotatably connected to the surface of the lever, the rotating sleeve being in contact with the inner wall of the toothed plate.
[0009] Preferably, the T-shaped plate is rotatably connected to the shaft, and the guide hopper is fixedly connected to the shaft.
[0010] Preferably, the surface of the hopper is bent to have an arc-shaped surface.
[0011] The beneficial effects of this utility model are:
[0012] This invention uses a stirring rod to stir the concrete guided into the chute cavity. Simultaneously, a turntable drives a guide hopper to oscillate back and forth outside the discharge hopper via a shaft. This oscillating guide hopper directs the concrete discharged from the discharge hopper, thus agitating the aggregate and fluid in the chute. This prevents segregation of the concrete during the guided flow, ensuring the concrete solidification effect. Furthermore, the oscillating design of the discharge hopper improves the uniformity of concrete distribution during discharge, preventing concrete accumulation.
[0013] 2. This utility model protects the concrete in the chute by setting up a cover plate, which prevents the concrete from splashing to the outside of the chute during the mixing process of the mixing rod, thereby avoiding material waste.
[0014] 3. This utility model limits the movement of the rack by setting the sleeve block, ensuring the stability of the rack during movement and preventing the rack from shaking during movement;
[0015] 4. By setting up a rotating sleeve, this utility model protects the inner wall of the shift shaft and the toothed plate by padding them, thus avoiding excessive wear when the shift shaft directly contacts the toothed plate.
[0016] 5. By setting the arc-shaped surface, this utility model allows the surface of the discharge hopper to be adapted to the swing path of the guide hopper, thus avoiding the collision and wear between the guide hopper and the surface of the discharge hopper during the swing process.

[0026] Figure 1-4 This invention illustrates an embodiment of a concrete guiding and solidification device for precast piles of highway bridges, comprising a chute 1. A stirring rod 2 is installed on the inner wall of the chute 1. The bottom of the stirring rod 2 is connected to a hopper 4. A guide hopper 5 is provided on the surface of the hopper 4. A T-shaped plate 6 is fixedly connected to the surface of the hopper 4. An electric telescopic rod 7 is fixedly connected to the surface of the T-shaped plate 6 by bolts. A turntable 8 is provided on the surface of the T-shaped plate 6 and a toothed plate 9 is rotatably connected to it via a rotating shaft. A rack 10 is fixedly connected to the output end of the electric telescopic rod 7 via a flange. The rack 10 and the toothed plate... Nine-phase meshing, the surface of the turntable 8 is welded with a pivot rod 12, and the surface of the turntable 8 is fixedly connected with a shaft rod 14. The rear end of the shaft rod 14 passes through the T-shaped plate 6 and the guide hopper 5 and is rotatably connected to the discharge hopper 4. The T-shaped plate 6 is rotatably connected to the shaft rod 14, and the guide hopper 5 is fixedly connected to the shaft rod 14. The surface of the discharge hopper 4 is bent with an arc surface 15.

[0027] Working Principle: When using this invention, the user pours concrete into the chute 1. At this time, the stirring rod 2 stirs the concrete guided in the inner cavity of the chute 1, preventing separation of the concrete during flow. Subsequently, the concrete enters the guide hopper 5 through the discharge hopper 4. At this time, the electric telescopic rod 7 drives the rack 10 to move back and forth, so that the rack 10 moves the pivot rod 12 through the toothed plate 9. Then, the pivot rod 12 drives the turntable 8 to rotate back and forth. Thus, the turntable 8 drives the guide hopper 5 to swing back and forth on the outside of the discharge hopper 4 through the shaft 14. This causes the guide hopper 5 to swing and guide the concrete discharged from the discharge hopper 4, realizing the agitation of aggregate and fluid in the chute, preventing segregation of concrete during guided flow, and thus ensuring the solidification effect of concrete. In addition, the swing setting of the discharge hopper can improve the uniformity of concrete distribution during discharge and prevent concrete accumulation.
[0028] In summary, this concrete guiding and solidification device for precast piles of highway bridges uses a stirring rod 2 to stir the concrete guided in the inner cavity of the chute 1. Simultaneously, the turntable 8 drives the guide hopper 5 to swing back and forth on the outside of the discharge hopper 4 via the shaft 14. This swinging guide hopper 5 guides the concrete discharged from the discharge hopper 4, thus agitating the aggregate and fluid in the chute and preventing segregation of the concrete during the guided flow. This ensures the solidification effect of the concrete. Furthermore, the swinging design of the discharge hopper improves the uniformity of concrete distribution during discharge and prevents concrete accumulation.
