介绍了塔式起重机回转装置的工作特性要求,论述了冲击载荷在塔式起重机工作过程中的不利影响;为了提高塔式起重机回转机构的工作性能,降低塔式起重机工作时的载荷冲击,设计了一种新型的塔式起重机液压回转机构。新型回转机构结构简单可靠、工作平稳、工作效率高,并且可以提供低速大扭矩,能够实现恒功率变速,具有实际意义和工业利用价值。
The working characteristics of the tower crane rotary device are introduced. The negative impact of the impact load on the tower crane is discussed. In order to improve the working performance of the tower crane and reduce the load shock when the tower crane is working, A New Type of Tower Crane Hydraulic Swing Mechanism. The new slewing mechanism has the advantages of simple and reliable structure, stable operation, high work efficiency, low torque and high torque, and constant speed of power transmission, which has practical significance and industrial utilization value.
