Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, the overhead traveling crane guide pulley device of prior art, steel rope 8 on winch drum 18 is upward through leading sheave 7, (opposite side is F2 to cause leading sheave 7 to be subject to a side force F1 at grooving rope area, wherein e is eccentric throw), affect the stability of leading sheave 7, the service life that makes generation wearing and tearing between rope race and steel rope, reduced bearing and steel rope.
As shown in Figure 2, the utility model be applicable to overhead traveling crane can the structural development of servo-actuated antifriction guide pulley device after, in leading sheave 7 rotary courses, leading sheave 7 can be adjusted in real time self angle with the swing of steel rope under the effect of steel rope 8, has avoided the wearing and tearing between rope race and steel rope.
With reference to Fig. 3, Fig. 4, Fig. 5, Fig. 6, the structure of the utility model device is, comprise fixed support 1, swinging mounting 2, lower rotating stand 10 and lower fixed bearing 13 that one welding combination is made, be fixedly installed a pair of concentric sleeve block 17 up and down on fixed support 1 top, be provided with base plate 19 in fixed support 1 lower horizontal
Be provided with axle sleeve 6 on swinging mounting 2 tops, be provided with bolt mounting holes (embodiment is four groups of bolt mounting holes) in swinging mounting 2 bottoms, axle sleeve 6 on swinging mounting 2 is socketed (hinged) by bearing pin 3 and the sleeve block 17 of fixed support 1, can realize the teeter between swinging mounting 2 and fixed support 1, bearing pin 3 upper ends have been provided with the bolt 1 of safety effect, are provided with lubricating cup 1 on bearing pin 3; On the swinging mounting 2 main mount pads in middle part, leading sheave 7 being housed, is the pivotable parts in the utility model device;
