Description

Technical Field

[0001] This utility model relates to the technical field of cement pipe pile production equipment, specifically to a centrifugal forming device for cement pipe piles. Background Technology

[0002] Prestressed concrete pipe piles refer to prestressed concrete piles with a circular cross-section formed using centrifugal and prestressing processes. They 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. However, traditional centrifugal molding devices for cement pipe piles do not have a limiting mechanism above the rotating roller. If impurities fall into the contact position between the mold and the roller when the roller rotates at high speed, the mold is prone to jumping, which can easily cause the mold to fly out of the centrifugal equipment, resulting in low safety.

[0017] The rotating mechanism 4 includes a vertical plate 41, a rotating rod 42, a first gear 43, a first stepper motor 44, a second gear 45, and a mounting rod 46. The vertical plate 41 is fixedly connected to the upper end of the top plate 34, and two sets of vertical plates 41 are provided. The rotating rod 42 is rotatably connected between the two sets of vertical plates 41. The first gear 43 is fixedly connected to the circumferential side of the rotating rod 42. The first stepper motor 44 is fixedly installed on the left side of the left vertical plate 41. The second gear 45 is fixedly connected to the output end of the first stepper motor 44, and the second gear 45 meshes with the first gear 43. The mounting rod 46 is fixedly connected to the circumferential side of the rotating rod 42, and two sets of mounting rods 46 are provided. Each set of mounting rods 46 has two sets of limiting wheels 5 installed at the bottom. When the mounting rod 46 is in a horizontal state and located above the pipe pile mold 14, the middle position of the two sets of limiting wheels 5 at the bottom of the mounting rod 46 is aligned with the central axis of the pipe pile mold 14.

[0018] A mechanism box 6 is fixedly connected to the upper end of the base plate 1, and two sets of rotating rollers 7 are rotatably connected to the right side of the mechanism box 6.

[0019] Four sets of support wheels 8 are fixedly connected to the side of the rotating roller 7, and a gear 9 is fixedly connected to the left end of the rotating roller 7. The gear 9 is rotatably connected inside the mechanism box 6.

[0024] In summary, the centrifugal molding device for cement pipe piles provided by this utility model, during operation, drives the gear 43 to rotate via the stepper motor 44, which in turn drives the rotating rod 42 to rotate synchronously. The rotation of the rotating rod 42 drives the mounting rod 46 to rotate, and the rotation of the mounting rod 46 can adjust the position of the limiting wheels 5. When the two sets of limiting wheels 5 at the bottom of the mounting rod 46 abut against the support wheel 15, the pipe pile mold 14 can be limited, thereby preventing the high-speed rotating pipe pile mold 14 from falling off. The top plate 34 can be raised and lowered via the electric cylinder 35, thereby adjusting the position and height of the limiting wheels 5, thus making the equipment suitable for pipe pile molds 14 of different specifications. The limiting ring on support wheel 18 engages with the inclined side of support wheel 2 15 to facilitate the installation of the pipe pile mold 14. At the same time, it can limit the support wheel 2 15, thereby preventing the pipe pile mold 14 from moving left or right. The motor body 10 drives gear 4 11 to rotate, and gear 4 11 drives gear 3 9 to rotate. At this time, the two sets of rotating rollers 7 rotate simultaneously. The rotating rollers 7 can drive support wheel 2 15 to rotate through support wheel 18, which can make the pipe pile mold 14 rotate. This structure can improve the stability of the pipe pile mold 14 when rotating.
