The emergency braking device for elevator safety comprises a fixing frame, a guiding sliding groove is formed in the inner side of the fixing frame, a fixing clamping plate is movably installed on the inner side of the guiding sliding groove, a first telescopic rod is installed at the top of the fixing clamping plate, and the top end of the first telescopic rod is installed on the inner side of the top of the guiding sliding groove. A second telescopic rod is mounted at the bottom of the fixed clamping plate and is mounted on the inner side of the bottom wall of the fixed frame; and a buffer rod is mounted on the outer wall of the bottom of the fixed frame. The extrusion rod is installed and fixed to the fixing frame, it is guaranteed that the extrusion rod is kept stable, the extrusion rod extends to drive the clamping piece to move on the inner side of the embedding groove, the two pressing plates get close to each other, the two pressing plates pressurize the guide rail, the friction force of the device is increased, the braking performance of the device is improved, and the braking effect is enhanced through cooperation with the anti-skid plate; and slipping caused by insufficient friction force of a single brake structure is avoided.

    本发明公开了一种电梯安全用紧急制动装置,包括固定框,所述固定框内侧安装有引导滑槽,所述引导滑槽的内侧活动安装有固定夹板,所述固定夹板的顶部安装有第一伸缩杆,所述第一伸缩杆的顶端安装在引导滑槽的顶部内侧,所述固定夹板的底部安装有第二伸缩杆,第二伸缩杆安装在固定框的底壁内侧;所述固定框的底部外壁上安装有缓冲杆。本发明通过安装有挤压杆,挤压杆固定在固定架上,保证挤压杆保持稳定,挤压杆伸长带动卡件在嵌合槽的内侧移动,两组施压板相互靠近,通过两组施压板对导轨进行加压,增大装置的摩擦力,增大装置的制动性,与防滑板配合增强制动效果,避免由于单个制动结构摩擦力不足出现打滑的情况。
