The invention relates to the technical field of door rolling machines, in particular to an anti-falling device applied to a door rolling machine, compared with the prior art, the anti-falling device comprises a fixed disc and a rotating cylinder, and the fixed disc and the rotating cylinder are matched with each other; the fixing disc is provided with a shaft sleeve, and a plurality of clamping blocks are arranged in the shaft sleeve. A throwing block is arranged on the rotating cylinder, the inner end of the throwing block is connected to a fastener in a sliding fit mode, and the outer end of the throwing block is connected with a spring; by arranging the throwing block in the rotating cylinder, when the rolling door descends at a constant speed, the throwing block cannot be thrown outwards under the action of the elastic force of the spring, when the rolling door descends at a high speed, the rotating cylinder rotates at an accelerated speed, and at the moment, the throwing block in the rotating cylinder is thrown outwards under the action of inertia, so that the rolling door falls downwards at a high speed. And the arc-shaped clamping head at the outer end of the throwing block is embedded into the clamping block in the fixed disc, so that the rotating cylinder stops rotating, and the door rolling machine stops falling downwards.
本发明涉及卷门机技术领域，特别是一种应用于卷门机的防坠落装置，与现有技术相比，该防坠落装置包括固定盘和转动筒，固定盘和转动筒相互配合；固定盘设有一轴套，轴套内设有若干个卡块；转动筒上设有甩块，甩块内端通过滑动配合连接在一紧固件上，甩块外端连接一弹簧；甩块与卡块相配合，甩块可在惯性的作用下嵌入卡块内，并由卡块卡住，通过在转动筒内设置一甩块，在卷门匀速下降时，甩块在弹簧的弹力作用下不会向外甩，当卷门急速向下坠时，转动筒加速转动，此时转动筒内的甩块在惯性作用下向外甩，使甩块外端的弧形卡头嵌入固定盘内的卡块内，从而使转动筒停止转动，卷门机停止向下坠落。
