Abstract

The invention discloses a protective device for an intelligent integrated actuator, and particularly relates to the technical field of intelligent electric actuators. The protective device comprises a first protective plate, a second protective plate and an oil storage tank, wherein the second protective plate is located above the first protective plate, and the oil storage tank is embedded and fixed in the middle of the first protective plate. According to the protective device for the intelligent integrated actuator, when stones fall to apply impact force to the second protective plate, a first transmission rod, a first guide block and a first spring match to play a role in preliminary buffering, at the moment, the impact force can be transmitted to the first protective plate, at the moment, a small piston is driven by a sliding rod to push hydraulic oil and extrude a third spring, so that the buffering effect can be achieved again, finally, a second transmission rod is pushed upwards through a large piston, a second spring is extruded by a second guide block, the final buffering effect is achieved, therefore the buffering effect is improved, and the problem that a protective device of an existing intelligent electric actuator is common in buffering effect is solved.

Description

Technical field

[0001] The present invention relates to the field of intelligent electric actuator, and in particular, to a protective device for intelligent integrated actuators.Background technique

[0002] The electric actuator refers to a driving device that provides a straight or rotational motion, which utilizes some kind of drive energy and working under certain control signals, and the electric actuator application environment is wide, need to apply to different environments, intelligent electric The actuator is also called the intelligent integrated actuator, the smart electric actuator has a smart control system, such as an actuator mounted in some channel caves, requires intelligent control.

[0003] Existing intelligent electric actuators, although the protective device is provided, when the corrosion of the channel is in contact with the protective device, the effect of the guard cushion is generally, resulting in the part of the intelligent electric actuator to be easily hit. Th...
