Abstract

The invention belongs to the technical field of elevator safety pliers, and particularly relates to high-speed elevator safety pliers. The high-speed elevator safety pliers comprise a safety plier base plate arranged on the top of a lift car, a clamping unit arranged on the safety plier base plate and used for clamping and braking of a steel wire rope, an electromagnetic driving unit arranged on the safety plier base plate and used for driving the clamping unit through a magnetic force attraction method, and a movable connecting unit arranged on the safety plier base plate and used for being in energized connection with the electromagnetic driving unit, and the safety plier base plate is arranged on the top of the lift car through a threaded connection unit. The high-speed elevator safetypliers have the advantages that the structure is simple and effective, clamping and braking operation is convenient and quick, braking response is sensitive, and normal use of an elevator is not affected.

Description

technical field [0001] The invention belongs to the technical field of elevator safety gear, and in particular relates to a high-speed elevator safety gear. Background technique [0002] Elevator safety gear refers to a type of clamping device that can clamp the wire rope to prevent the elevator car from continuing to move when the elevator needs emergency braking. It is used to ensure the safety of the elevator car when it is in danger. In the prior art, most elevator safety gears have the problems of insufficient clamping action and insufficient clamping strength. [0003] The patent announcement number is CN2552893Y, and the Chinese utility model patent whose announcement date is 2003.05.28 discloses a kind of elevator safety gear. It includes a bracket, the top and the center of the bottom plate of the bracket have grooves, and the elevator guide rails are located in the grooves. Wedge blocks, guide bodies and springs are arranged sequentially from inside to outside on...
