混凝土联锁块主要用于港口地面铺设。唐山市第一建筑公司混凝土构件厂生产的联锁块具有强度高、外表平整等优点,该产品已通过鉴定。其主要生产设备联锁块成型机由该厂自行设计和制造,这在国内属于首创。其中ZPJ-0-1高频振动器采用行星内滚道式结构,在电机转速1440r/min条件下,实现15700r/min的高频振动,使干硬性混凝土迅速密实成型。但是,由于该高频振动器设计缺乏足够的理论依据,结构设计也不尽合理,工作中经常出现故障,使正常生产难于进行。为此,笔者分析了该振动器的故障原因并提出改进措施,取得了令人满意的结果。
The concrete interlocking block is mainly used for laying on the ground of the port. The interlocking block produced by the Concrete Component Factory of Tangshan No. 1 Construction Co., Ltd. has the advantages of high strength and smooth appearance, and the product has passed the identification. Its main production equipment interlock block molding machine is designed and manufactured by the factory itself, which is the first in the country. The ZPJ-0-1 high-frequency vibrator adopts the planetary inner raceway structure and realizes high-frequency vibration of 15700r/min under the condition of the motor rotation speed of 1440r/min, so that the dry and hard concrete can be rapidly and compactly formed. However, due to the lack of a sufficient theoretical basis for the design of the high-frequency vibrator, the structural design is also not reasonable, and malfunctions often occur in the work, making normal production difficult to carry out. For this reason, the author analyzed the cause of the malfunction of the vibrator and proposed improvement measures, and achieved satisfactory results.
