Miniature intelligent remote control electro-hydraulic actuator

Abstract

The invention relates to the technical field of actuators and discloses a miniature intelligent remote control electro-hydraulic actuator. The miniature intelligent remote control electro-hydraulic actuator comprises a hydraulic cylinder sleeve. A drive motor in a miniature power unit drives a gear pump to rotate to output high pressure hydraulic oil, the high pressure hydraulic oil output by theminiature power unit passes through a valve block to enter the hydraulic cylinder sleeve in a hydraulic actuator, a rack is pushed to conduct straight travel motion, the rack drives a gear shaft to conduct angular travel motion, the gear shaft drives a main gear to rotate, the main gear drives a driven gear outside the main gear to rotate, an angle encoder on the gear can receive an electric appliance pulse signal when the driven gear rotates, a control feedback module of 4-20 mA converts a 4-20 mA signal which is in linear ratio with the angle change position, and the rotation angle is transmitted to a mobile phone APP client side or a computer terminal through the control feedback module by means of a Bluetooth module. In this way, remote monitoring is achieved, and the purpose of convenient use is achieved.

Description

technical field [0001] The invention relates to the technical field of actuators, in particular to a miniature intelligent remote control electro-hydraulic actuator. Background technique [0002] As a power device, the actuator is a device that receives control information and exerts control on the controlled object in the automation technology tool. The precise control of the position of the object is not only used in the drive and control of various valves, but also has been widely used in many fields such as electric power, water conservancy, metallurgy, papermaking, aerospace, pipelines, petrochemical, industrial equipment and food processing, etc. parts. [0003] At present, there are various electro-hydraulic actuators on the market. For example, Chinese patent CN 103174698B discloses an electro-hydraulic actuator, which uses an electromechanical braking device to brake the rotor of the motor to maintain a relatively high pressure in the hydraulic circuit. , it can m...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a miniature intelligent remote control electro-hydraulic actuator, which has the advantages of being convenient to use, and solves the problem that the device cannot accurately control and adjust the rotation angle of the electro-hydraulic actuator, and the volume is relatively small. Large, not suitable for ships with high requirements in small spaces, and the operation is not convenient enough, and a series of detection and switch operations cannot be performed remotely, resulting in the problem of low convenience
