SHOCK-ABSORBING DEVICE FOR CANTILEVER CRANE SYSTEM, CANTILEVER CRANE SYSTEM AND PUMPING MACHINE

摘要

A shock-absorbing device for a cantilever crane system of a pumping machine is disclosed, which includes a body (200), a rotary body (100), an adjustable speed motor (300) and a control mechanism (400).The control mechanism has a vibrating sensor (410) and a processor (420). The vibrating sensor detects an initial vibration signal for characterizing the initial vibration of the cantilever crane system. The processor runs the adjustable speed motor according to the obtained initial vibration signal instruction detected by the vibrating sensor to make the rotary body rotate and produce a stabilized vibration, the direction of which is opposite to the vibrating direction of the initial vibration. The device is used for offsetting part of the initial vibration of the cantilever crane system, so as to reduce the vibration of the cantilever crane system.
