The invention relates to the technical field of lifting devices, in particular to a powerful sling for an emergency elevator. The powerful sling for the emergency elevator comprises a sling body and further comprises a mounting frame, a clamping mechanism and a buffering mechanism, and a through hole is formed in the mounting frame; the clamping mechanism is erected on the mounting frame; and the buffering mechanism is connected with the clamping mechanism. According to the powerful sling for the emergency elevator, a speed measuring device is used for monitoring the movement speed of the sling, when the speed exceeds the standard, the clamping mechanism is started, a round roller is clamped through a pressing claw, the friction force borne by the round roller is increased, and therefore the round roller is prevented from rotating rapidly, and the movement speed of the round roller is reduced; while the clamping mechanism clamps the round roller, the buffering mechanism can be driven to clamp the sling, and the sling is rubbed through anti-slip strips arranged on arc-shaped clamps, so that the descending speed of the sling under the action of the gravity of the elevator is reduced.
本发明涉及提升装置技术领域,尤其涉及一种应急电梯用强力吊索。所述应急电梯用强力吊索包括吊索,还包括安装架,所述安装架上开设有通孔;夹持机构,所述夹持机构架设在安装架上;缓冲机构,所述缓冲机构与夹持机构相连接。本发明提供的应急电梯用强力吊索,利用测速装置监测吊索的运动速率,当速率超标时启动夹持机构,通过紧迫爪对圆辊进行夹持,增加圆辊所受摩擦力,从而防止圆辊快速转动,减缓圆辊运动的速度,而在夹持机构对圆辊夹持的同时,能够带动缓冲机构对吊索进行夹持,通过弧形夹上所设置的防滑条,对吊索进行摩擦,以减缓吊索在电梯重力作用下所下降的速率。
