China's first pre-prepared PHC pipe pile pumping equipment off the assembly line

Recently, the HBT80·14·132SG pipe pile pump, the first pre-prepared pumping equipment for PHC pipe piles in the domestic concrete machinery industry, was rolled off the line in the Zoomlion Industrial Park of Zoomlion, and promoted the “clamping front-loading fabric technology”. Industrialization of an advanced production process for prefabricated PHC pipe piles.

At present, in the production process of prefabricated PHC pipe piles, the "clamping post-placement fabric technology" is commonly used. This process requires 4 to 6 people to carry out the process of smoothing and cleaning the concrete at the top and bottom molds. The labor intensity is large and the production efficiency is low, which seriously restricts the production capacity of the prefabricated pipe piles and soil. At the same time, there are lax mold seals and pipe molds. Deformation risk.

In order to solve the technical problems in the industry, Zoomlion set up a technical research team composed of experts from the National Concrete Machinery Engineering Technology Research Center and the Research Institute of Concrete Machinery Co., Ltd., with the cooperation of the production, materials and other departments, from the scene data collection to the product Assembly off the assembly line, all members work overtime to complete the HBT80 · 14 · 132SG pile pump development.

It is reported that the HBT80·14·132SG pile pump has inherited the original superior performance of the Zoomlion pump, but also has many new features. It has independent intellectual property rights of the negative inclined pumping unit, which improves the suction efficiency of the C80 high-viscosity concrete. The double-drive stirring system increases the stirring torque and makes the stirring shaft more even and reasonable, ensuring the concrete in the Uniform flow in the hopper improves suction performance; new distribution buffer patented technology improves the service life of the swing cylinder and S-tube; new wear-resistant materials and welding process improve the wearing parts such as eyeglass plate, cutting ring and S-tube. The service life of the new type of stirring seal structure improves the service life of the stirring seal.
