为加速我国铁路动力革命,实现我局机车內燃化,我队和第一工程大队接受了广州机务段原洗修库改建为內燃机车轮修库的设计与施工任务。改建车库重点是需要升高整个屋面(包括桁架)和吊车梁工程。当时提出了两个方案:一是拆了重盖(称掀顶方案);一是将原屋面和吊车梁顶升(称顶升方案)。经三结合小组研究,认为“顶升”方案是符合多快好省总路线精神的,因此,决定采用,并派员去上钢五厂学习(上钢五厂在“顶升”工程中,采用特制的顶升工具,用4.5瓧马达电动同步顶升)。根据我局的实际情况,有防洪T型钢塔架材料,但缺乏同类型的马达,经过多次比选和
In order to speed up the revolution of railway in our country and realize the internal combustion of our locomotive, our team and the first engineering brigade accepted the design and construction tasks of rebuilt the original repair depot of Guangzhou locomotive depot as the wheel repair garage of a diesel locomotive. Rebuilding the garage focuses on the need to raise the entire roof (including truss) and crane beam works. At that time, two proposals were made: one was to demolish the overburden (called the lift plan); the other was to lift the original roof and the crane beam (called ascended plan). According to the study by the three combined groups, the “top-up” plan is in line with the spirit of the principle of “making the province more efficient and more economical.” Therefore, it was decided to adopt it and dispatched personnel to study at No. 5 Steel Works Special lifting tool, with 4.5 瓧 motor electric synchronized jacking). According to the actual situation of our bureau, there is flood control T-shaped steel tower material, but the lack of the same type of motor, after many comparison and selection
