The invention discloses an elevator anti-falling centrifugal ball device. The device comprises anti-falling gears, wherein the anti-falling gears are installed on the side, away from a heavy object, of an elevator car, and the plurality of anti-falling gears are arranged on the elevator car; a tooth wall is arranged on the outer side of the elevator car, wherein teeth on the tooth wall mesh with the anti-falling gears, fixing frames are arranged on the two sides of the axis of each anti-falling gear, and a locking sliding rail is arranged on each fixing frame; a locking support is installed in each locking sliding rail, locking teeth are arranged at the top of each locking support, a spring is installed at the bottom of each locking support, one end of each spring is installed at the bottom of the corresponding locking support, and a sensitive ball is arranged at the other end of the corresponding spring. Compared with the prior art, the elevator anti-falling centrifugal ball device has the advantages that the sensitive balls are moved out of the bottom of the locking supports through weightlessness, the locking supports integrally fall down under the action of gravity so that the anti-falling gears can be fixed, the elevator car is prevented from continuously falling, and thus safety is achieved. The whole device is simple in structure, low in cost and quite convenient to install, and therefore has good market prospects.
本发明公开了一种电梯防坠离心球装置,包括防坠齿轮,防坠齿轮安装在电梯轿厢远离重物一侧,电梯轿厢上设有若干防坠齿轮,电梯轿厢外侧设有齿墙,齿墙上的齿和防坠齿轮啮合,防坠齿轮轴心处两侧设有固定架,固定架上设有锁紧滑轨,锁紧滑轨内部安装有锁紧支架,锁紧支架顶部设有锁紧齿,锁紧支架底部安装有弹簧,弹簧的一端安装在锁紧支架底部,另一端上设有敏感球。本发明与现有技术相比的优点在于:通过失重将敏感球移出锁紧支架底部,因为重力的作用使锁紧支架整体下坠,从而固定住防坠齿轮,阻止电梯轿厢继续下落,是十分安全的,整个装置的结构简单,成本低,安装起来也十分的方便,具有很好的市场前景。
