Problems solved by technology
[0003] At the moment of elevator braking, due to the huge inertia of the entire elevator equipment, a huge impact force can be generated during braking. The existing fall arrester adopts friction braking, which can reduce the impact force, but the braking time of friction braking is long , and prone to slipping, a greater safety risk

The invention discloses an elevator emergency brake anti-falling device. The elevator emergency brake anti-falling device comprises a power receiving device connected with a moving object and used forreceiving object power in the vertical or horizontal direction, a sensing device connected with the power receiving device and used for sensing the motion speed of the object, a locking device arranged on one side of the sensing device and used for being matched with a guiding rail, and a withdrawing device arranged on the locking device and used for controlling the locking device to withdraw a locking state; the sensing device, the locking device and the withdrawing device are all arranged on a table plate and connected with the moving object through the table plate; the locking device is arranged to be switched between the locking state and an un-triggering state; and the withdrawing device comprises a power output part for outputting the power, and a power input part for receiving rotational force and transferring the rotational force to the power output part, and both the power output part and the power input part are parts which can make rotational motion around the axis of the power output part and the power input part.
Description
technical field [0001] The invention relates to the field of protection, in particular to an elevator fall arrester. Background technique [0002] The anti-fall device is also called the speed difference device, which can quickly brake and lock the falling object within a limited distance. The anti-fall device is mainly used in the safety protection of elevators and elevators to avoid damage to personnel and equipment caused by the rapid decline of elevators and elevators. [0003] At the moment of elevator braking, due to the huge inertia of the entire elevator equipment, a huge impact force can be generated during braking. The existing fall arrester adopts friction braking, which can reduce the impact force, but the braking time of friction braking is long , and is prone to slipping, which poses a greater safety risk. Contents of the invention [0004] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide an elevator eme...
