[0026] The utility model is further described below in conjunction with the accompanying drawings:

[0027] like Figure 1-Figure 6 As shown, a prestressed concrete pipe pile production auxiliary device includes a support mechanism 1, a driving mechanism 3 for movement is arranged below the support mechanism 1, and also includes a distribution mechanism 2 for uniformly filling concrete;

[0028] In this embodiment, the material distributing mechanism 2 includes a lower hopper 21, the bottom of the lower hopper 21 is arc-shaped, an arc-shaped baffle for guiding concrete to flow out from both sides is arranged in the middle position inside the lower hopper 21, an opening for concrete to pass through is opened at the lower end of the lower hopper 21, four fixed columns 22 are welded on the upper sides of the lower hopper 21, and the four fixed columns 22 are symmetrically distributed, two support rods 23 are fixedly connected to the lower sides of the lower hopper 21, and rollers 24 are rotatably connected to the lower side of the support rods 23, and a concave platform 25 is arranged under the lower hopper 21, and the concave platform 25 is arranged under the lower hopper 21. A mold 27 is provided in the middle of the concave platform 25, and limit plates 26 are installed at the front and rear of the concave platform 25. A plurality of arc-shaped bosses 28 are provided above the concave platform 25 at the position of the roller 24. There is a distance between two arc-shaped bosses 28 just enough for the roller 24 to pass through, and the distance is evenly distributed. Baffles are provided on both sides of the arc-shaped bosses 28 to prevent the roller 24 from deviating. The steel cage is placed in the mold 27, and the fixed column 22 and the support rod 23 are used to support the lower hopper 21. The concrete enters the steel cage from both sides under the guidance of the arc-shaped baffle of the lower hopper 21.

[0029] In this embodiment: the driving mechanism 3 includes five transmission shafts 31, and the five transmission shafts 31 are evenly distributed on the bottom side of the concave platform 25. Two tires 32 are fixedly connected to both ends of the transmission shaft 31. A bevel gear set 33 is provided on a transmission shaft 31 close to the limiting plate 26. The bevel gear set 33 is fixedly connected to the output shaft of the motor 34. The motor 34 is fixedly connected to the limiting plate 26. When the motor 34 is started, the output shaft of the motor 34 controls the rotation of the transmission shaft 31 through the bevel gear set 33, and the tires 32 on the transmission shaft 31 rotate synchronously, pushing the other tires 32 to rotate, thereby driving the concave platform 25 to move.

[0030] In this embodiment: the support mechanism 1 includes two portal frames 11, and a feeding bucket 12 for guiding concrete into the lower hopper 21 is welded between the two portal frames 11. The portal frames 11 are respectively provided with four annular bosses 13 at the positions of the fixed columns 22. A groove is provided at the center of the annular bosses 13. The end of the fixed column 22 away from the lower hopper 21 is slidably connected in the annular bosses 13. The feeding bucket 12 is used to transport concrete into the lower hopper 21, and the annular bosses 13 are used to fix the lower hopper 21.

[0031] Working principle: First, put the steel cage into the mold 27, pour the concrete from the feeding bucket 12 into the lower hopper 21, the arc-shaped baffle inside the lower hopper 21 diverts the concrete to both sides, and the concrete enters the steel cage from the bottom of the lower hopper 21. The arc-shaped bottom of the lower hopper 21 can cushion the fall of the concrete without damaging the steel cage, and at the same time make the distribution more uniform and the appearance better. At this time, start the motor 34, and the motor 34 controls the transmission shaft 31 to rotate through the bevel gear set 33. The transmission shaft 31 drives the tire 32 to rotate, and the concave platform 25 is driven to move along the lower side of the lower hopper 21 through multiple sets of tires 32. The movement of the platform 25 drives the mold 27 inside it to move synchronously from under the lower hopper 21. At this time, the arc-shaped boss 28 on the concave platform 25 moves from under the roller 24. As the arc-shaped boss 28 moves linearly, it pushes the roller 24, so that the roller 24 rolls over the arc-shaped boss 28. Then, under the action of multiple arc-shaped bosses 28, the roller 24 reciprocates up and down, thereby driving the lower hopper 21 to vibrate and accelerate the falling of concrete. The fixed column 22 slides in the annular boss 13 to support the lower hopper 21. The reciprocating motion of the lower hopper 21 makes the concrete fall faster to avoid clogging the steel cage.

[0032] When both ends of the concave platform 25 move to the position of the lower hopper 21, the limiting plate 26 abuts against one side of the lower hopper 21 to prevent the concrete from spilling on the ground and to make the concrete distribution more sufficient.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
