外部振动器目前使用最多的是平板式振动器和附着式振动器。随着混凝土施工发展的需要,对外部振动器要求也更高了。然而,我国生产外部振动器的工厂,由于没有统一的标准,设计参数较乱,因而不适应用户的需要,在这里,提出几点看法。1.平板式混凝土振动器和附着式混凝土振动器,虽然其基本结构原理相同,但两者的工况载荷不同,其工作情况是不一样的。附着式是靠底部的螺栓或其他锁紧装置固定在模板、滑槽、料斗上等,间接把振动传递给混凝土或其它被振动的物料,很少用于振实混凝土,大都用作振动运输、振动给料或振动筛分等。而平板式振动器则在振动器底部附加一块适当
The most commonly used external vibrators are plate vibrators and attachment vibrators. With the development of concrete construction, the requirements for external vibrators are even higher. However, there are no uniform standards in China’s factories that produce external vibrators, and the design parameters are chaotic. Therefore, they do not meet the needs of users. Here, we have made several observations. 1. Flat-plate concrete vibrators and attached concrete vibrators, although their basic structural principles are the same, but the operating conditions of the two are different, and their working conditions are not the same. Attachment type is based on the bottom of the bolt or other locking device fixed on the template, chute, hopper, etc., indirect transmission of vibration to the concrete or other materials being vibrated, rarely used to tap concrete, mostly used for vibration transport, Vibration feeding or vibration screening. The flat plate vibrator attaches a suitable piece to the bottom of the shaker
