Abstract

A rope slack-preventing device of a lift includes a rope end plate (8), a rotating component (2), a switch fixing frame (3) and a supporting frame of the rotating component. Under the rope end plate (8), the rotating component (2) is suspended by the supporting frame of the rotating component and a safety switch (4) is suspended by the switch fixing frame (3). The supporting frame of the rotating component includes a fixing-supporting plate (6) and an elastic support column. One end of the fixing-supporting plate (6) is fixedly connected with the rope end plate (8), and the other end is hinged with the rotating component (2) by a pin shaft (7). The elastic support column includes a screw rod (1) and a pressing spring (5) sleeved around the screw rod. When the rotating component (2) is pressed to rotate around the pin shaft, the switch striking plate pushes the movable contact of the safety switch (4). The device can automatically cut off power supply to brake the lift such that accident of clashing head due to breakage of steel wire rope during the car running is effectively avoided and safety of the lift is guaranteed during the lift operation. The quality of the product can be effectively improved.

Description

technical field [0001] The invention relates to an anti-loosening rope device, which is used as a safety device for braking an elevator when an elevator wire rope is accidentally loosened or broken, and belongs to the technical field of elevator safety. Background technique [0002] When the ultra-high-speed elevator is running, if the wire rope is accidentally loosened or broken, it cannot be seen when the shaft is closed, which may cause subsequent accidents and even cause irreparable losses. Therefore, it is necessary to design a structure that can respond quickly to abnormal conditions such as wire rope loosening, and a safety device that brakes the elevator. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides an elevator rope-loosening prevention device, which can quickly respond to abnormal conditions such as wire rope looseness, and brake the running of the elevator. [0004] For realizing above technical p...
