澳大利亚莫尼尔公司的罗克拉预应力混凝土管制造技术,是世界先进制管技术之一,已被包括发达国家在内的二十多个国家所采用。我国从澳大利亚引进的罗克拉成套制管生产线,于1987年在辽阳水泥制品厂通过验收,投入正式生产。它的建成投产,对我国三阶段管生产线的技术改造和新厂建设具有示范作用。本文重点对主要引进装备的工作原理、技术参数、主要特点、消化吸收进展情况及进一步开发创新的建议等作一简要介绍。希望这一介绍能对该套引进装备的消化吸收及开发创新工作有所帮助。一、悬辊机悬辊机是用来成型管芯的(见图1)。管模由悬辊轴带动旋转。混凝土进入料斗后,通过布料机进入喂料机,由喂料机将其喂入管模,成型管芯。
Monique’s Roquela prestressed concrete pipe manufacturing technology is one of the world’s advanced pipe-making technologies and has been adopted by more than 20 countries including developed countries. China’s introduction of Australia from the Rokra complete sets of pipe production line, in 1987 in Liaoyang Cement Product Factory passed acceptance, put into formal production. Its completion and production have demonstrated the technical transformation of the three-stage pipe production line in our country and the construction of a new factory. This article focuses on a brief introduction to the working principles, technical parameters, main features, digestion and absorption of the main introduction equipment, and suggestions for further development and innovation. It is hoped that this introduction will help the digestion and absorption of the introduced equipment and the development of innovative work. First, the suspension roller machine is used to mold the die (see Figure 1). The tube mold is rotated by the suspension roller shaft. After the concrete enters the hopper, it enters the feeder through the distributing machine and feeds it into the tube mold by the feeder to form the tube core.
