The invention relates to the technical field of elevator safety tongs, and particularly discloses an anti-skid elevator safety tongs for elevator braking safety and a using method thereof.The anti-skid elevator safety tongs for elevator braking safety comprise a device outer shell of a square hollow structure, and the device outer shell and an elevator car are fixedly installed through a fixing plate fixedly installed on the side face of the device outer shell; a receding groove is formed in the middle of the device outer shell, the receding groove corresponds to an elevator guide rail installed in an elevator shaft, and an acceleration sensor used for detecting out-of-control falling of an elevator is fixedly installed on the inner wall of the device outer shell. According to the antiskid elevator safety tongs for elevator braking safety and the using method thereof, a second air bag is extruded through an extrusion ball, air in the second air bag enters a first air bag through a connecting hose, at the moment, the first air bag expands and pushes a mounting plate, extrusion between the mounting plate and an elevator guide rail is increased, and therefore the contact friction force is increased; and the condition of slipping caused by overlarge acceleration is prevented.
本发明涉及电梯安全钳技术领域,具体公开了一种电梯制动安全用防滑型电梯安全钳及其使用方法,包括呈方形空心结构的装置外壳体,所述装置外壳体通过其侧面固定安装的固定板与电梯轿厢之间固定安装,所述装置外壳体中间位置开设有避让槽,且所述避让槽与安装在电梯井内部的电梯导轨之间互相对应,并且所述装置外壳体内壁固定安装有用于检测电梯失控下坠的加速度传感器。该电梯制动安全用防滑型电梯安全钳及其使用方法,利用挤压球对第二气囊进行挤压,使得第二气囊中的空气通过连接软管进入到第一气囊中,此时第一气囊膨胀并推动安装板,增加在安装板与电梯导轨之间的挤压,从而增加接触摩擦力,防止因加速度过大而出现打滑的情况。
