在混凝土预制构件厂和建筑工地的混凝土作业中,为了了保证混凝土质量,都要用相应的振动机械对所浇灌的混凝土进行振捣,这样,不但质量好,而且工效也高。因此,混凝土振动机械就成了混凝土施工中必不可少的而又很重要的常备机械设备。常用的混凝土振动机械有插入式振动器(图1)、附着式振动器(图2)、平板式振动器和振动台四种。它们所用的动力多数是电动的,少数为内燃机和风动的。在这几种振动器中,使
In order to ensure the quality of concrete in the concrete prefab plant and construction site, vibrating concrete should be vibrated with a corresponding vibrating machine. In this way, not only the quality is good, but also the work efficiency is high. Therefore, concrete vibrating machinery becomes an indispensable and important standing equipment for concrete construction. Commonly used concrete vibrating machines include plug-in vibrators (figure 1), attached vibrators (figure 2), plate vibrators, and vibratory tables. Most of the power they use is electric, and a few are internal combustion engines and pneumatic. In these types of vibrators,
