Radial locking anti-falling device

XUE JIAN

The invention discloses a radial-stopping falling prevention device which comprises a follow-up chain wheel shaft, a follow-up chain wheel, a stopping wheel and a radial stopping unit, wherein the axis of the follow-up chain wheel shaft is horizontally arranged, the follow-up chain wheel freely rotates around the follow-up chain wheel shaft, the stopping wheel is connected with the follow-up chain wheel in a fastened mode and coaxially installed, and a first stopping structure is manufactured on the outer circumference of the stopping wheel. The radial stopping unit comprises a stopping mechanism consisting of a stopping element and a mounting seat, and a displacement driving mechanism consisting of an electromagnetic driving linear displacement element and a resetting element which are triggered to operate by an output signal of the equipment control system; one end of the stop element is provided with a stop structure II matched with the stop mechanism I, the other end of the stop element can perform horizontal reciprocating displacement in the mounting seat, and the mounting position corresponds to the horizontal radial position of the stop wheel; the reset state of the displacement driving mechanism enables the first stop mechanism and the second stop mechanism to be meshed or combined, and the car carrying plate is prevented from falling. And in the action state, the first stop mechanism is separated from the second stop mechanism, and lifting operation of the vehicle carrying plate is not hindered.

本申请一种径向止动的防止下坠装置，包括轴线水平设置、紧固安装在设备机架的随动链轮轴，绕随动链轮轴自由转动的随动链轮，与随动链轮紧固连结、同轴安装、外圆周制作有止动结构一的止动轮，径向止动单元；径向止动单元包括由止动元件、安装座组成的止动机构、由设备控制系统输出信号触发运行的电磁驱动直线位移元件、复位元件组成的位移驱动机构；止动元件的一端设置有与止动机构一匹配的止动结构二，另一端能够在安装座内部作水平往复位移，安装位置与止动轮水平径向位置相对应；位移驱动机构的复位状态使得止动机构一与止动结构二啮合或结合，防止载车板下坠；动作状态使得止动机构一与止动结构二脱离，不妨碍载车板升降运行。
