The invention provides a safety braking device for a traction elevator and a braking method of the safety braking device, and relates to the field of elevators. The safety braking device for the traction elevator comprises an elevator car, a cable breakage braking device used for braking, a buffering device used for buffering when falling occurs, a traction steel wire rope used for the traction elevator and a protective sleeve used for improving the braking effect. According to the safety braking device for the traction elevator, the traction steel wire rope is punctured through the puncture cone, and the anti-disengaging barbs are connected with steel wires spirally twisted together in the traction steel wire rope in a clamped mode after puncturing the interior of the traction steel wire rope, so that the fixing effect on the traction steel wire rope is achieved; gas above the buffer partition plate is discharged downwards through the center communicating pipe for pressure relief buffering, the moving distance of buffering is increased in the mode that pressure relief is conducted through buffering on one side, and harm to human bodies in the elevator car is reduced by increasing the stroke of buffering and reducing reverse thrust after buffering.
本发明提供一种曳引电梯用安全制动装置及其制动方法,涉及电梯领域。该曳引电梯用安全制动装置,包括电梯箱、用于进行制动的缆绳断裂制动装置、在发生坠落时进行缓冲的缓冲装置、用于曳引电梯的曳引钢丝绳索和提高制动效果的保护套。该曳引电梯用安全制动装置,通过穿刺锥对曳引钢丝绳索进行穿刺,防脱倒刺穿刺至曳引钢丝绳索内部后,与曳引钢丝绳索内部的螺旋拧在一起的钢丝进行卡接,从而实现对曳引钢丝绳索的固定效果,进行缓冲时,缓冲隔板上方的气体通过中心连通管向下排出进行泄压缓冲,通过一边缓冲进行泄压的方式,提高缓冲的移动距离,通过增大缓冲的行程并减小缓冲后反向的推力从而减小对电梯箱内部人体的伤害。
