The invention provides an overload working system and mechanical equipment, and relates to the technical field of mechanical equipment. According to the overload working system, when the rotation driving mechanism of the mechanical equipment drives the steel wire rope to be wound in, whether the rotation driving mechanism of the mechanical equipment is overloaded or not can be judged, when the rotation driving mechanism is overloaded, the rotation driving mechanism is controlled to stop, and the steel wire rope is gradually wound in through driving force output by the telescopic driving mechanism; the length of the steel wire rope between the lifting appliance and the telescopic driving mechanism is shortened, the lifting appliance can continue to complete the operation needing to be completed when the steel wire rope is wound in by the rotary driving mechanism due to the shortening of the steel wire rope, and the telescopic driving mechanism can output the output force larger than that of the rotary driving mechanism under the driving of the same power source. Therefore, larger driving force can be provided through the telescopic driving mechanism to meet the overload requirement during sling operation, then overload work of mechanical equipment is achieved, and the requirement for normal engineering operation is met.
本发明提供了一种超载工作系统及机械设备,涉及机械设备技术领域。本发明的超载工作系统在机械设备的旋转驱动机构驱动钢丝绳卷入时,可判断机械设备的旋转驱动机构是否超载,并在旋转驱动机构超载时,控制旋转驱动机构停机,通过伸缩驱动机构输出的驱动力使得钢丝绳逐渐出现卷入,使得吊具与伸缩驱动机构之间的钢丝绳的长度缩短,而钢丝绳的缩短使得吊具能够继续完成旋转驱动机构卷入钢丝绳时所需要完成的作业,而在同样的动力源的驱动下,伸缩驱动机构能够输出比旋转驱动机构大的输出力,从而能够通过伸缩驱动机构提供更大的驱动力来满足吊具作业时的超载需要,进而实现机械设备的超载工作,满足工程作业正常进行的需要。
