Abstract
The utility model discloses a car crane rope anticreep groove pulley, its characteristics are assisted before the crane pole head assembly pulley and add a set of anticreep groove pulley, constitute biax double pulley closed assembly pulley with the body of rod, free rotation including the pulley rope and can not deviate from. The anti-drop groove pulley for the crane rope is reasonable in structure, firm, durable and long in service life.
Description
The utility model relates to a kind of automobile hoist rope anticreep groove pulley.
At present, the groove separation preventing device of automobile hoist rope is that when the crane special operation, pulley rotates with straight iron rod retaining rope, and sliding rope can be extruded from the slit of iron rod and gin wheel, greatly affects the work operations of crane.
The purpose of this utility model is, for addressing the above problem well, and designed a kind of automobile hoist rope anticreep groove pulley.This pulley be crane body of rod gin wheel axle just before, the auxilliary sleeve anti-drop groove assembly pulley that adds of allocation, three large pulleys of three anticreep groove small sheaves and lifting wheels are corresponding, wheel maintains the minimum clearance that does not rub mutually with the top of wheel, there is skidding to support between the wheel of anticreep groove pulley and wheel and between wheel and suspension rod wall, and the free gap is arranged, anticreep groove pulley can freely be rotated.The crane body of rod, gin wheel group and anticreep groove assembly pulley constitute twin shaft sister block closed type assembly pulley, and the crane rope can not be deviate from interior rotation.
The purpose of this utility model realizes by following measure:
On the crane body of rod, bore knock hole, fixed installation anticreep groove sheave shaft, be set with anticreep groove pulley and skidding on this axle, anticreep groove sheave shaft is positioned at gin wheel axle dead ahead, the U type groove of the gin wheel on the U type groove of the anticreep groove pulley on it and the gin wheel axle is corresponding, and two pulley tops maintain the minimum clearance that does not rub mutually.The crane body of rod, gin wheel group, anticreep groove assembly pulley constitute twin shaft sister block closed type assembly pulley, and the crane rope can not be deviate from interior rotation.
The utility model is simple in structure, and structure is reasonable, and member is sturdy and durable, and long service life is the ideal device of automobile hoist rope anticreep groove card rope.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
