The invention relates to the field of elevator safety, and discloses a progressive elevator safety gear which comprises a supporting seat, an elevator safety gear, an elevator safety gear and an elevator safety gear. The two friction plates are arranged up and down and located on the same side of the rail groove; the wedge block is located on the other side of the rail groove and used for extruding the friction plate above the wedge block, and the wedge block is connected with the elevator speed limiter through a pull rod; the transfer frame is mounted on the supporting seat; the rotating rod is rotationally arranged on the adapter frame; the extrusion block and the wedge block are arranged on the same side, the extrusion block and the rotating rod are connected through a connecting rod, and the extrusion block is used for extruding the friction plate below; and the linkage mechanism is mounted in the adapter frame and the supporting seat, and is used for moving the wedge block to link the rotation of the rotating rod. In the rapid moving process of the wedge blocks, the extrusion blocks are driven to extrude the guide rails, the upper wedge blocks and the lower extrusion blocks act on the guide rails at the same time, the stress points of the guide rails are not single, the braking stability of the lift car is improved, and shaking of the lift car is reduced.
本申请涉及电梯安全的领域,并公开了一种渐进式电梯安全钳,包括:支撑座,安装于轿厢上;摩擦片,上下设置有两片,且位于轨槽的同一侧;楔块,位于轨槽的另一侧,并用于向上方的摩擦片方向相挤压,楔块与电梯限速器之间通过拉杆相连接;转接架,安装于支撑座上;旋转杆,转动设置于转接架上;挤压块,与楔块同侧,挤压块与旋转杆之间通过连接杆连接,挤压块用于向下方的摩擦片挤压;联动机构,安装于转接架和支撑座中,并用于楔块的移动来联动旋转杆的旋转。本申请实现了在楔块快速移动过程中,带动挤压块向导轨挤压,上面的楔块和下面的挤压块同时作用在导轨上,导轨受力点非单一,提高了轿厢制动的稳定性,减少轿厢晃动。
