Description

Technical Field

[0001] The invention relates to the technical field of pipe pile production and processing, in particular to a centrifugal device for preventing vibration in concrete pipe pile production. Background Art

[0002] Pipe pile centrifugation is an important step in the production process of pipe piles. The pipe piles are rotated at high speed on the centrifugal pipe pile mold in the centrifuge, causing the concrete in the pipe pile mold to undergo high-speed centrifugal motion, and finally a concrete pipe pile with a circular hole in the center is made. Centrifugal molding is a very important process for the manufacture of prestressed concrete pipe piles. It directly affects the concrete strength of the pipe pile and the uniformity of the concrete along the entire length of the pipe pile.

[0003] At present, the existing pipe pile centrifuge has the following technical problems when performing centrifugal operation on the concrete pipe pile mold: the pipe pile mold will produce axial and radial runout during centrifugation, resulting in the pile body concrete in the pipe pile mold not being compacted, resulting in insufficient strength of the concrete pipe pile after molding. In addition, it will lead to poor uniformity in the molding of the pipe pile, greatly reducing the bearing capacity of the concrete pipe pile. Therefore, improvements are urgently needed to address this problem. Summary of the Invention

[0015] 1. The present invention is provided with an anti-axial runout device, in which the running wheel of the concrete pipe pile mold is placed. When the concrete pipe pile mold as a whole undergoes axial runout, the symmetrically arranged axial pressure plates produce contact pressure on the axial pressure plates.

During the centrifugal rotation of the pipe pile mold, if the pipe pile mold undergoes radial runout, the tube wall of the concrete pipe pile mold will contact and press the radial pressure block in the anti-radial runout device. The second spring limits and buffers the displacement of the radial pressure block, thereby preventing the concrete pipe pile mold as a whole from radial runout to the greatest extent, improving the uniformity and stability of the concrete pipe pile during the centrifugal process, and improving the strength and bearing capacity of the concrete pipe pile.
