Abstract
The utility model discloses a remote control device utilizing a stepping motor to drive a manual valve. The remote control device comprises an electronic control handle, a PLC, a motor driver, the stepping motor, a linear displacement potentiometer, a shifting fork and the manual valve, wherein the electronic control handle, the PLC, the motor driver, the stepping motor, the shifting fork and the manual valve are sequentially connected. One end of the linear displacement potentiometer is connected with the stepping motor, and the other end of the linear displacement potentiometer is connected with the PLC. According to the remote control device utilizing the stepping motor to drive the manual valve, the electronic control handle emits a command signal to control the stepping motor to rotate, then the stepping motor drives the manual valve, and a speed-reduction hybrid stepping motor converts an electric pulse signal into an angular displacement so as to rotate a manual valve handle through the shifting fork. Under the non-overloaded condition, the rotating speed and the stopping position of the stepping motor only depend on the frequency and the number of pulses of the pulse signal rather than are affected by load change. Meanwhile, according to the remote control device utilizing the stepping motor to drive the manual valve, the manner of pulling the electronic control handle and the manner of operating the manual valve handle on site are identical, and the remote control device utilizing the stepping motor to drive the manual valve is visual, simple, convenient to use, and convenient for personnel to operate.
Description
Technical field
The utility model relates to hydraulicdriven technical field, particularly adopts stepper motor to drive the remote control unit of hand behaviour valve.
Background technique
In the situation that current ship deck mechanical high-speed development, every boats and ships have the actuator such as many winches to drive, and are in order to alleviate crewman's labor intensity, more and more to concentrating remotely-controlled requirement.And the main device that drives is exactly hand behaviour valve, and hand behaviour valve is for the control of the hydraulic pressure of controlling being carried out machine travel direction and speed.Existing hand behaviour valve can only at the scene by manually pulling hand behaviour valve handle, can't be concentrated long-distance remote control.Because the location comparison of general each hand behaviour valve on boats and ships disperses, stem and ship stern have distribution, and be less or need can not in time control each actuator in the central controlled situation the crewman.
Cause above-mentioned reason: because hand peculiar to vessel behaviour valve is a kind of manual ship valve, mode of operation only has manually-operable to carry out mechanically operated mode.It can only decide by manually pulling the operating valve handle aperture of spool by the angular dimension that rotates, with speed and the direction of control actuator motion.So not only precision is low in the process of control, and often have the untimely situation of operation.
The model utility content
The shortcoming that the purpose of this utility model is to overcome prior art provides a kind of remote control unit that adopts stepper motor to drive hand behaviour valve with not enough.
The purpose of this utility model is achieved through the following technical solutions:
Employing stepper motor of the present utility model drives hand behaviour's valve remote control unit, comprise be used to the electric control handle that sends handle rotation command signal, for the PLC that receives handle rotation command signal, for the stepper motor driver that handle rotation command signal is changed into angular displacement signal, stepper motor, straight-line displacement potentiometer, fork and hand behaviour valve, described electric control handle, PLC, stepper motor driver, stepper motor, fork and hand behaviour valve are linked in sequence, described straight-line displacement potentiometer one end connects stepper motor, and the other end connects PLC.
Preferably, described stepper motor is the deceleration composite stepper motor.
Preferably, the angle pulled of described electric control handle and the hand behaviour valve angle of rotating equates.
Preferably, described hand behaviour valve comprises hand behaviour valve handle, and described fork is provided with the perforate with hand behaviour valve handle shape and size coupling, and described hand behaviour valve handle passes this perforate and fork is fixed.
Preferably, the mode that is threaded connection of described fork and hand behaviour valve is fixed.
Working principle of the present utility model is: this remote control unit is rotated motion by the electric control handle control step motor at integrated console, drives the on-the-spot hand behaviour valve handle of fork control and is rotated action.Electric control handle is mainly used in operator and sends control signal at central station of floating dock, its operation is the same with the on-site manual mode of operation, front and back promote operating grip can be to the turn signal of behaviour's valve handle of selling, reach electric control handle and move how many angles, the stepper motor band is started to grasp the valve handle and is rotated how many angles.
The utility model has following advantage and effect with respect to prior art:
1, the utility model adopts electric control handle to send command signal control step electric machine rotation, and the mode of pulling electric control handle is the same, intuitively easy with the mode of execute-in-place hand behaviour valve handle, the convenient operation personnel operation.
2, the utility model adopts the rotation of stepper motor to drive the straight-line displacement potentiometer and sends feedback signal, and the angle that assurance hand behaviour valve handle rotates is identical with the angle that electric control handle is pulled.
3, the utility model adopts stepper motor to drive hand behaviour valve, in the situation that non-overload, the deceleration composite stepper motor rotates hand behaviour valve handle by fork, the rotating speed of motor depends on frequency and the umber of pulse of pulse signal, stop position depends on that the straight-line displacement potentiometer sends feedback signal, is not subjected to the impact of load variations.
4, the utility model employing stepper motor rotates the drive fork and stirs hand behaviour valve handle, and fork can sway, thereby can easily contact with hand behaviour valve handle or separate.
