The invention provides a hydraulic damping passive control elevator rolling guide shoe. The vibration control cost, noise, weight and space can be greatly reduced while the vibration reduction requirement of a high-speed elevator is met. The roller is rotationally mounted on the rocker arm; the long rod is fixed on the guide shoe bracket; the pre-tightening nut is fixed on the long rod; the pre-tightening spring is sleeved on the long rod; a cylinder barrel of the hydraulic actuator is installed on the guide shoe support in a hinged mode, and a piston rod of the hydraulic actuator is hinged to the rocker arm. The interior of the cylinder barrel is divided into a left cavity and a right cavity by a piston of a piston rod of the cylinder barrel, and each cavity is provided with an external oil port. The hydraulic damper is installed in the hydraulic pipeline and divides the hydraulic pipeline into a left cavity pipeline and a right cavity pipeline, the left cavity pipeline is connected with an external oil port in the left cavity of the cylinder barrel, and the right cavity pipeline is connected with an external oil port in the right cavity of the cylinder barrel; one end of the energy accumulator hydraulic pipeline is connected with the right cavity pipeline, and the other end is connected with the hydraulic energy accumulator; and the hydraulic one-way valve is mounted on the hydraulic pipeline of the energy accumulator.
本发明提供一种液压阻尼被动控制电梯滚动导靴,在满足高速电梯的减振需求的同时又能大幅度降低振动控制成本、噪声、重量和空间。滚轮转动安装在摇臂上;长杆固定在导靴支架上;预紧螺母固定在长杆上;预紧弹簧套装在长杆上;液压作动器的缸筒铰接安装在导靴支架上,液压作动器的活塞杆和摇臂铰接;缸筒内部被其活塞杆的活塞隔成左右两个腔体,每个腔体上都设置有一个外接油口;液压阻尼器安装在液压管路内,将液压管路分隔成左腔管路和右腔管路,左腔管路与缸筒左腔体上的外接油口连接,右腔管路与缸筒右腔体上的外接油口连接;蓄能器液压管路一端与右腔管路连接,另一端与液压蓄能器连接;液压单向阀安装在蓄能器液压管路上。
