Abstract

The invention belongs to the technical field of electric actuating mechanisms, and discloses an electric actuating mechanism hand wheel self-locking mutual assurance device. The electric actuating mechanism hand wheel self-locking mutual assurance device comprises a shell, the two ends of the shell are fixedly connected with a motor cover and a hand wheel mounting cover through bolts correspondingly, a driving motor is arranged inside the motor cover, a hand wheel is arranged on the outer wall of one side of the hand wheel mounting cover, a worm wheel, a controller and a hollow worm are arranged inside the shell, the hollow worm is located between the worm wheel and the controller, moreover, the two ends of the hollow worm are connected with the driving motor and the hand wheel in a rotating mode correspondingly. According to the electric actuating mechanism hand wheel self-locking mutual assurance device, a first locking piece, a second locking piece and a switching screw rod are arranged, so that during manual and automatic switching the electric actuating mechanism, the positioning states between the two locking pieces and two bevel gears is changed synchronously by utilizing extension and retraction of the switching screw rod, then the actuating mechanism can automatically form locking of the other structure when the driving mode is replaced, hereby, the effect of synchronous self-locking is achieved.

Description

technical field [0001] The invention belongs to the technical field of electric actuators, and in particular relates to a handwheel self-locking and mutual protection device of an electric actuator. Background technique [0002] An electric actuator refers to a drive device that can provide linear or rotary motion, and generally includes two modes of manual drive and electric drive, so that the mechanism can be controlled with or without electricity. [0003] However, the operation and structure of the switching devices in the existing actuators are mostly complicated. For example, it is necessary to press the hand wheel for a long time to realize the closing of the manual structure during manual driving, and a secondary lock is required after switching, which affects the switching speed. The complex switching structure leads to high production cost and assembly cost, and if manual switching is performed during a power failure, there are often situations where the electric d...
