The invention provides a heavy hydraulic lifting platform with a stable lifting function and a control method thereof. The heavy hydraulic lifting platform comprises a base, a shear fork frame, a hydraulic cylinder, a lifting platform, a pull rope, a winch, an angle detection mechanism, a distance measuring mechanism, a pressure maintaining device and a controller. The controller controls the working state of the hydraulic cylinder through information detected by the distance measuring mechanism so as to drive the lifting platform to ascend and descend to the designated height. After the lifting platform is lifted to the specified height, when the controller detects that the pressure in the hydraulic cylinder is reduced, the controller supplements the pressure to the hydraulic cylinder through the pressure maintaining device and adjusts the height of the lifting platform by cooperating with the distance measuring mechanism and the hydraulic cylinder again, so that stable control over the height position of the lifting platform is achieved; the controller can control the working states of the winches at all the positions of the lifting platform according to information detected by the angle detection mechanism and the tension sensor so as to balance the torque at the two ends of the lifting platform, stable lifting of the lifting platform is achieved, and good safety performance is achieved.

    本发明提供了一种具有平稳升降功能的重型液压升降台及其控制方法,包括底座、剪叉架、液压缸、升降平台、拉绳、卷扬机、角度检测机构、测距机构、保压装置和控制器,控制器通过测距机构检测到的信息控制液压缸的工作状态以驱使升降平台升降至指定高度;在升降平台升降至指定高度后,当控制器检测到液压缸内压力变小时,控制器通过保压装置对液压缸进行压力补充并重新配合测距机构和液压缸调节升降平台的高度以实现对升降平台高度位置的稳定控制;控制器能够根据角度检测机构和张力传感器检测到的信息控制升降平台各个位置处的卷扬机的工作状态,以平衡升降平台两端的力矩,实现升降平台的稳定升降具有较好的安全性能。
