The slide rail chute in the straight direction, the slide rail chute divides the trapezoidal chute into symmetrical left wedge chute and right wedge chute. The wedge-shaped gate blocks respectively fitted with the left wedge-shaped chute and the right wedge-shaped chute are movably connected with the left wedge-shaped chute and the right wedge-shaped chute, and can slide up and down along the vertical protrusion. The wedge-shaped gate block is close to the side of the slide rail chute All are provided with a wear-resistant layer, and the limit plate used to prevent the wedge-shaped block from falling out is installed and fixed on the front of the support.
进一步的，所述耐磨层为均匀密布的棱锥凸起。Further, the wear-resistant layer is uniform and densely distributed pyramid protrusions.
进一步的，所述楔形闸块材质为生铁。Further, the wedge-shaped block is made of pig iron.
本实用新型具有如下有益效果：The utility model has the following beneficial effects:
电梯滑轨置于滑轨滑槽中，当电梯速度异常时，安全钳启动，两块夹紧电梯滑轨的楔形闸块分别沿着左楔形滑槽和右楔形滑槽向上滑动，从而锁紧电梯滑轨，使电梯停止升降；楔形闸块表面设有棱锥凸起的耐磨层，极大地提高了楔形闸块与电梯滑轨间的摩擦力，提高电机反应速度；本实用新型具有结构简单、成本低、安全性能高的特点。The elevator slide rail is placed in the slide rail chute. When the elevator speed is abnormal, the safety gear is activated, and the two wedge-shaped brake blocks clamping the elevator slide rail slide upward along the left wedge-shaped chute and the right wedge-shaped chute respectively, thereby locking The elevator slide rail makes the elevator stop lifting; the surface of the wedge-shaped gate block is provided with a wear-resistant layer with pyramidal protrusions, which greatly improves the friction between the wedge-shaped gate block and the elevator slide rail, and improves the motor response speed; the utility model has the advantages of simple structure , low cost and high safety performance.
