The anti-falling safety braking device comprises a fixing plate and a guide column, the guide column is fixedly installed on the bottom face of the fixing plate, a transverse column is arranged below the fixing plate, the guide column penetrates through the upper surface of the transverse column and is in sliding connection with the transverse column, and a tensioning mechanism is arranged on the upper surface of the fixing plate. The invention relates to the technical field of ladder safety braking devices. According to the anti-falling safety braking device of the car-type elevator, by arranging the tensioning mechanism, when the car-type elevator falls, the output end of the reduction gearbox drives the connecting shaft and the steel cable winch to rotate, the steel cable winch rotates reversely to lift the first-section steel cable and the second-section steel cable upwards so as to pull the elevator car upwards, and the bottom end of the second-section steel cable is fixedly connected with the compression spring; the compression spring and the second steel cable are fixed through the fastening bolt to form a closed loop, and the compression spring can be extruded when the first steel cable and the second steel cable are tensioned, so that the compression spring is deformed to generate reset elastic force to buffer impact generated during tensioning to a certain extent.
本发明公开了一种厢式电梯的防坠落安全制动装置,包括固定板和导向柱,导向柱固定安装于固定板底面,固定板下方设置有横柱,导向柱穿过横柱上表面与横柱滑动连接,固定板上表面设置有拉紧机构。本发明涉及梯安全制动装置技术领域。该厢式电梯的防坠落安全制动装置,通过设置拉紧机构,在厢式电梯出现坠落的时候,减速箱的输出端带动连接轴和钢缆绞盘转动,钢缆绞盘反转向上提拉一段钢缆和二段钢缆,从而拉动电梯厢向上,二段钢缆底端固定连接压缩弹簧,压缩弹簧通过紧固螺栓与二段钢缆固定形成闭环,在一段钢缆和二段钢缆拉紧时能够对压缩弹簧进行挤压,使得压缩弹簧受到形变从而产生复位的弹力对拉紧时产生的冲击进行一定程度上的缓冲。
