Abstract

The invention discloses a locking device for an external electromechanical actuator, which relates to the technical field of electromechanical actuators and comprises: a base on which an actuator, a support rod and a locking device are arranged; Seat, at least one detachable auxiliary jaw, and two clamping arms pivotally connected to the mounting base through a pivot shaft, the clamping arm includes a large arm and a small arm that are located on both sides of the pivot shaft and connected as a whole, the two A first clamping opening is formed between the small arms, and a drive mechanism for driving the rotation of the two clamping arms is also provided on the mounting base. The auxiliary jaws include two symmetrical crank arms, and the crank arms have a pivoted arm and a hinge arm connected to each other. The clamp arm, the two pivot arms intersect with each other through the pin shaft and are coaxially pivoted on the mounting seat, a second clamping opening is formed between the two clamp arms, and the cantilever ends of the two pivot arms are respectively connected to the corresponding Forearm swivel connection. The locking device of the present application realizes multiple locking of the actuator, and the locking is more stable, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of electromechanical actuators, in particular to a locking device for an external type electromechanical actuator. Background technique [0002] In the engineering application of actuation technology, according to the requirements of specific working conditions, the actuator needs to be locked after the maximum extension to prevent the actuator from retracting under the influence of load and other uncontrollable factors and causing accidents. The current locking device needs to be manually locked, which is cumbersome to operate, and can only be locked once. When the locking device suddenly fails, the actuator will be released suddenly, which may cause the actuator to retract suddenly and quickly, which poses a certain safety hazard. , low security, and thus poor practicability. [0003] Therefore, there is an urgent need for a locking device for electromechanical actuators that is easy to operate and reliab...
