Abstract:
A winding roll lifting device, comprising:a main body including a driving mechanism for moving a winding roll between a vertical position and a horizontal position, said main body having a first end and a second end opposite said first end; a supporting arm having a first end and a second end opposite said first end, said first end of said supporting arm being pivotally connected to said first end of said main body so that said supporting arm is operable to pivot about said first end of said main body; a hook member having a base end pivotally connected to said second end of said supporting arm so that said hook member extends from said supporting arm and is operable to pivot about said second end of said supporting arm; and a chuck member having a distal end to be inserted into a central recess of the winding roll so as to engage the central recess, and having a base end opposite said distal end, said base end being pivotally connected to said second end of said main body so that said chuck member is operable to pivot about said second end of said main body; wherein said main body, said supporting arm, and said chuck member are arranged such that said driving mechanism is operable to drive said chuck member so that said chuck member pivots about said second end of said main body to thereby move between a vertical position and a horizontal position, and such that said supporting arm pivots about said first end of said main body in synchronization with the pivotal movement of said chuck member so as to move in a direction approaching and extending away from said chuck member, whereby said chuck member is operable to move the winding roll between the vertical position and the horizontal position when said distal end of said chuck member is inserted into and engages the central recess of the winding roll.
