Be installed with at least two at least one support beam in the said support beam of the said equilibrium arm left and right sides and be used for adjustment structure that the reel installation site is adjusted; Each said adjustment structure includes the riser that is fixedly arranged on the corresponding said support beam or column and can adjust the adjustable bolt that is screwed on riser or the column along fore-and-aft direction; Two said adjustment structures are positioned at the inboard or the outside of said winch underframe, and pass through the front and back crossbeam of the said winch underframe of said adjustable bolt roof pressure separately respectively.
Be positioned on the said adjustable bolt of both sides before and after said riser or the column and be equipped with the jam nut that said adjustable bolt is fixed.
Described two adjustment structures all are positioned at the inboard of said winch underframe, and respectively the said adjustable bolt roof pressure through separately on the medial surface of crossbeam before and after the said winch underframe.
Be positioned at said reel the place ahead at said winch underframe and be provided with the whippletree that extends along left and right directions, slip cap is provided with rope winding jib on the said whippletree.
The utility model with the winch underframe through being bolted on the equilibrium arm; At least one bolt penetration hole is for extending slotted hole along fore-and-aft direction in the bolt penetration hole that the said bolt of confession that is provided with on every group of equilibrium arm and the said underframe passes; So in use, when deflection appears in steel rope, when can not keep vertical with spool axis; Can bolt be unscrewed; Utilize the position of the adjust the clearance winch base of bolt in slotted hole then, the spool axis on the winch base keeps vertical again with steel rope, the bolt of screwing again winch base; Solved in the prior art owing to can't adjust the reel position when steel rope can not keep vertical with spool axis, steel rope increases with the reel friction and is easy of the problem that twists in reel one end.
Further, the adjustment structure is set on the support beam of equilibrium arm, when needing adjustment winch position base, or only need tightens and unscrew corresponding adjustable bolt and get final product, very convenient.
Further, on the winch base, rope winding jib is set, can guarantees the vertical of steel rope and spool axis better.
