The invention relates to the technical field of elevators, in particular to an elevator hydraulic speed reduction method, when a car body stalls, an elevator hydraulic speed reduction device can quickly sense that the car body is in a stall state and immediately send a signal to a microcontroller, and the microcontroller controls oil pumps on four sets of miniature direct-current hydraulic push rods to work to drive the car body to rotate. And then the miniature direct-current hydraulic push rod is driven to drive the roller to rotate, the rubber skirt anticlockwise rotates to 90 degrees along with the roller, and four sets of friction force opposite to the gravity direction are generated between the rubber skirt and the wall of the electric well, so that the stall elevator is decelerated. The speed reduction device has the beneficial effects that the speed reduction of the stall elevator can be effectively realized, so that personnel and property in the elevator are protected from being damaged.
本发明涉及电梯技术领域,具体涉及一种电梯液压减速方法,在轿厢本体失速时,电梯液压减速装置能够迅速感知到轿厢本体处于失速状态,并立即向微控制器发送信号,微控制器通过控制四组微型直流液压推杆上的油泵工作,进而驱动微型直流液压推杆带动滚筒转动,橡胶裙边随着滚筒逆时针转动至90°,通过橡胶裙边与电井壁间产生四组与重力方向相反的摩擦力,从而达到对失速电梯减速。本发明的有益效果在于:能够有效的实现对失速电梯进行减速,从而保护电梯中的人员及财产不受损伤。
