Abstract

The invention discloses an emergency trip hanging buckle device. The emergency trip hanging buckle device comprises a shell, a trigger, a manual racket rod, a hanging buckle, a manual racket rod handle, a reset rod, a conical valve shell, a valve shaft, a limiting switch and an electric actuator, wherein the trigger is rotatably arranged on one side of the shell; the trigger is connected with oneend of the manual racket rod through a trigger spring; one end of the hanging buckle is clamped with the bottom end of the trigger, and the other end of the hanging buckle is rotatably arranged on theshell; the manual racket rod handle is arranged on the shell, and one end of the manual racket rod handle is connected with the other end of the manual racket rod; the other end of the manual racketrod handle is connected with the reset rod through a manual racket rod spring; and one end of the reset rod is connected with the hanging buckle. The emergency trip hanging buckle device is compact instructure, convenient to mount, small in occupied space and diverse in braking mode when applied to a steam turbine, and the steam turbine can be stopped manually or electrically under emergency conditions.

Description

technical field [0001] The invention relates to an emergency blocking hook device, which belongs to the technical field of steam turbine emergency braking. Background technique [0002] The safety system, control system and operating system of the steam turbine all need to be equipped with an emergency braking device, which needs to be able to realize the functions of normal startup and shutdown of the steam turbine, manual emergency shutdown, overspeed mechanical shutdown of the steam turbine, etc., but most of the braking devices in the prior art only have A braking method, so once a fault occurs, it is difficult to play its due role before the fault is eliminated, and it cannot meet customer needs. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide an emergency blocking hook device, which is compact in structure, easy to install, and takes up little space. It is applied to steam turbines and ha...
