The invention discloses a piston type elevator buffer device and relates to an elevator buffer device. The elevator buffering device is mainly designed for solving the problem that an existing elevator buffering device needs to be provided with an elevator shaft and a pit. The upper end of the cylinder is connected with an upper flange cover which is provided with an upper vent hole, and the lower end of the cylinder is connected with a lower flange cover which is provided with a lower vent hole; a plurality of grooves are formed in the outer circle of a piston in the air cylinder, and supporting rings or sealing rings are arranged in the grooves. The jackscrew extends into the groove in the side wall of the piston to fix the traction rope. And the lower end of the traction rope extends out of the lower ventilation hole. The top of the piston is fixed with a choke plug, and a traction rope passes through the piston and the choke plug. The two or more air cylinders are arranged on all the side faces of the elevator car. The top of the air cylinder is connected with the upper frame body, the traction rope is fixed to the top of the elevator car after winding around guide wheels of the upper frame body, the bottom of the air cylinder is connected with the lower frame body, and the traction rope is connected to the bottom of the elevator car after winding around guide wheels of the lower frame body. The method has the advantage that an elevator shaft and a pit are not needed.

    活塞式电梯缓冲装置涉及一种电梯缓冲装置。主要是为解决现有电梯缓冲装置需设电梯井及地坑的问题而设计的。它包括气缸,气缸上端连有上法兰盖,上法兰盖有上通气孔,气缸下端连有下法兰盖,下法兰盖有下通气孔;气缸内的活塞外圆上有若干道沟槽,沟槽内有支承环或密封圈;顶丝从活塞侧壁的沟槽伸入对牵引绳进行固定。牵引绳上端从上通气孔伸出,下端从下通气孔伸出。活塞顶部固定阻气塞,牵引绳从活塞和阻气塞中部通过。气缸为二个或多个,设置在电梯箱的各个侧面。气缸顶部连接上架体,牵引绳绕经上架体的导向轮后固定在电梯箱的顶部,气缸底部连接下架体,牵引绳绕经下架体的导向轮后连接在电梯箱的底部。优点是无需设置电梯井及地坑。
