Core drill system for excavator

Abstract

A core drill system for an excavator according to the present invention comprises: an excavator connection unit provided to be coupled to the excavator; a pillar unit which is vertically installed next to one side of the excavator connection unit; a support frame unit supporting the excavator connection unit and the pillar unit; a core drill unit which is supported by being engaged with a gear unit provided in the pillar unit and provided to drill a target object; and a first motor which provides the core drill unit with the driving power so that the core drill unit drills the target object while moving in the vertical direction, wherein the pillar unit includes a plurality of connecting portions which are each connected to a support frame included in the support frame unit, and the pillar unit is attachable/detachable via the plurality of connecting portions.

1 . A core drill system for an excavator, the core drill system comprising:
 an excavator connection unit configured to be coupled to an excavator;   a pillar unit mounted in a vertical direction beside the excavator connection unit;   a support frame unit configured to support the excavator connection unit and the pillar unit;   a core drill unit engaged with and supported by a gear unit provided at the pillar unit, the core drill unit being configured to perforate an object; and   a first motor configured to supply power to the core drill unit so that the core drill unit moves in the vertical direction to perforate the object,   wherein the pillar unit comprises a plurality of connection portions, and the plurality of connection portions is connected to a plurality of support frames provided at the support frame unit, and   wherein the pillar unit is provided so as to be mountable and demountable through the plurality of connection portions.   
     
     
         2 . The core drill system according to  claim 1 , wherein the gear unit provided at the pillar unit comprises a rack gear, and
 wherein the core drill unit comprises a core body configured to define a framework of the core drill unit and to be engaged with the rack gear so as to be movable upward and downward and a core blade connected to the core body to perforate the object.   
     
     
         3 . The core drill system according to  claim 2 , further comprising a second motor configured to supply rotational power to the core blade. 
     
     
         4 . The core drill system according to  claim 1 , further comprising a reducer connected to the first motor to supply power less than power generated by the first motor to the core drill unit. 
     
     
         5 . The core drill system according to  claim 2 , further comprising a reducer connected to the first motor to supply power less than power generated by the first motor to the core drill unit. 
     
     
         6 . The core drill system according to  claim 4 , wherein the core drill unit perforates the object while being moved downward in the vertical direction by power controlled by the reducer. 
     
     
         7 . The core drill system according to  claim 5 , wherein the core drill unit perforates the object while being moved downward in the vertical direction by power controlled by the reducer. 
     
     
         8 . The core drill system according to  claim 1 , wherein the excavator connection unit comprises:
 a fixing frame fixedly coupled between the support frame unit and the excavator connection unit, the fixing frame being configured to be rotatable 360 degrees; and   pillar frames extending in a horizontal direction and connected to a distal end of an arm of the excavator and to an end of a tipping link connected to the arm of the excavator.   
     
     
         9 . The core drill system according to  claim 1 , wherein the first motor is implemented as a hydraulic motor and is driven using a pressure control method. 
     
     
         10 . The core drill system according to  claim 2 , wherein the first motor is implemented as a hydraulic motor and is driven using a pressure control method. 
     
     
         11 . The core drill system according to  claim 2 , wherein the core blade of the core drill unit is configured to be connectable to another core blade so that an overall length of the core blade increases.
