Unmanned control system of operation lever for operating device

Abstract

An unmanned control system of an operation lever for operating a device includes: a mountable operation unit which is attachably and separably coupled to an operation lever for operating a device and manipulates the operation lever; and an operation unit control part which moves the operation lever coupled to the mountable operation unit by remotely controlling the mountable operation unit, in which the mountable operation unit has the same degree of freedom as the operation lever. The unmanned control system may lower a center of gravity of the mountable operation unit, thereby precisely controlling the operation lever and improving intuition with respect to the movement of the operation lever and the mountable unit.

The invention claimed is: 
     
       1. An unmanned control system of an operation lever for operating a device comprising:
 a mountable operation unit which is attachably and separably coupled to an operation lever for operating a device and manipulates the operation lever; and 
 an operation unit control part which remotely control the mountable operation unit to move the operation lever coupled to the mountable operation unit, 
 wherein the mountable operation unit has a same degree of freedom as that of the operation lever, 
 wherein the mountable operation unit includes: a link adapter which is separably and attachably coupled to the operation lever; a base adapter which is mounted on the device; and a drive unit which is mounted on the base adapter and operates the link adapter, and 
 wherein the link adapter includes: a guide rod which is rotatably connected to the drive unit; a sliding member which rectilinearly moves or slides on and along the guide rod; a lever fastening member which is fastened to the operation lever; and a link member which rotatably connects the lever fastening member and the sliding member to each other. 
 
     
     
       2. The unmanned control system of  claim 1 , wherein the link adapter further includes a rotary link member which rotatably connects the link member with the sliding member. 
     
     
       3. The unmanned control system of  claim 2 , wherein the link member includes a support portion which is connected to the lever fastening member, and a connecting portion which extends in a direction parallel to a center of the support portion and rotatably connected to the rotary link member. 
     
     
       4. The unmanned control system of  claim 3 , wherein the connecting portion is eccentric from the center of the support portion. 
     
     
       5. The unmanned control system of  claim 1 , wherein the link adaptor further includes: an inclination compensation member between the link member and the lever fastening member, and the inclination compensation member includes a parallel maintaining portion which is in contact with the lever fastening member and an inclination maintaining portion which is in contact with the link member. 
     
     
       6. The unmanned control system of  claim 2 , wherein one end of the rotary link member is rotatably connected to the link member and the other end thereof is rotatably connected to the sliding member. 
     
     
       7. The unmanned control system of  claim 1 , wherein the sliding member includes a linear bushing which moves along the guide rod. 
     
     
       8. The unmanned control system of  claim 2 , wherein a rotation center of one end of the rotary link member and a rotation center of the other end thereof are orthogonal to each other. 
     
     
       9. The unmanned control system of  claim 1 , wherein the guide rod is formed to have a length which prevents the sliding member from being separated from an upper end of the guide rod. 
     
     
       10. The unmanned control system of  claim 1 , wherein the base adapter includes a base portion which is fixed to a lever housing in which a lower end of the operation lever is positioned, and a motor support portion which extends from the base portion and on which the drive unit is mounted. 
     
     
       11. The unmanned control system of  claim 10 , wherein a through hole through which the operation lever passes is formed in the base portion, and a concave stepped portion is formed between the through hole and an edge of the base portion. 
     
     
       12. The unmanned control system of  claim 11 , wherein the base portion further includes a clamp which is fastened to an upper end of the lever housing and an edge of the through hole. 
     
     
       13. The unmanned control system of  claim 10 , wherein the drive unit includes a first motor which is mounted on the motor support portion and a second motor which is provided to be rotatable by driving power of the first motor. 
     
     
       14. The unmanned control system of  claim 13 , wherein the first motor is fixedly installed on the motor support portion and the second motor is connected to an output shaft of the first motor and rotatably installed on a second motor support portion. 
     
     
       15. The unmanned control system of  claim 14 , wherein a lower end of the guide rod is rotatably connected to an output shaft of the second motor. 
     
     
       16. The unmanned control system of  claim 15 , wherein the output shaft of the first motor is parallel to a rotation center of the other end of the rotary link member and the output shaft of the second motor is parallel to a rotation center of one end of the rotary link member.
