Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
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, make to produce between rope race and steel rope the service life of wear and tear, reduce bearing and steel rope.
As shown in Figure 2, overhead traveling crane of the present invention can after the structural development of servo-actuated antifriction guide pulley device, in leading sheave 7 rotary course, leading sheave 7 can adjust self-view in real time with the swing of steel rope under the effect of steel rope 8, avoids the wearing and tearing between rope race and steel rope.
With reference to Fig. 3, Fig. 4, Fig. 5, Fig. 6, the structure of apparatus of the present invention is, comprise one welding and combine the fixed support 1, swinging mounting 2, lower rotating stand 10 and the lower fixed bearing 13 that are made, about a pair concentric sleeve block 17 is fixedly installed on fixed support 1 top, fixed support 1 lower horizontal is provided with base plate 19
Swinging mounting 2 top is provided with axle sleeve 6, bolt mounting holes (embodiment is four groups of bolt mounting holes) is provided with in swinging mounting 2 bottom, axle sleeve 6 on swinging mounting 2 is socketed (hinged) by the sleeve block 17 of bearing pin 3 with fixed support 1, the teeter between swinging mounting 2 and fixed support 1 can be realized, bearing pin 3 upper end has been provided with the bolt 1 of safety effect, bearing pin 3 is provided with lubricating cup 1; In the middle part of swinging mounting 2, main mount pad being equipped with leading sheave 7, is the pivotable parts in apparatus of the present invention;
Fixed support 1 lower raft 19 is fixedly connected with lower fixed bearing 13 by bolt 3 11 and locating dowel pin 12, lower fixed bearing 13 is provided with the steel rope raised up and crosses borehole jack 16, and the line of centers that the steel rope on lower fixed bearing 13 crosses borehole jack 16 is coaxial with the line of centers of fixed support 1 lower bottom plate hole, for being passed down through steel rope 8
Cross on borehole jack 16 outer wall at the steel rope of lower fixed bearing 13 and be set with lower rotating stand 10, lower rotating stand 10 is provided with packing ring 14 with the contact surface of lower fixed bearing 13, realizes lower rotating stand 10 and crosses freely rotating of borehole jack 16 around the steel rope of lower fixed bearing 13; Four groups of bolts hole on lower rotating stand 10 connect by four groups of bolts 29 are corresponding with four groups of bolts hole of swinging mounting 2 lower end; Steel rope is crossed on borehole jack 16 and is provided with lubricating cup 2 15.
The principle of work of apparatus of the present invention is:
With reference to Fig. 2, rig is in the process of making a trip, when steel rope 8 axially moves along winch drum 18, except steel rope 8 pairs of leading sheaves 7 apply except larger tensile force f, steel rope 8 also can apply a side force F1 (opposite side is F2) to the grooving of leading sheave 7 under the effect of tensile force f, because swinging mounting 2 can swing within the specific limits around fixed support 1, therefore, the side force of steel rope 8 pairs of leading sheave 7 groovings will force swinging mounting 2 to rotate certain angle around fixed support 1, reach the object reducing steel rope 8 pairs of track adjusting wheel grooving side forces, steel rope 8 is only had larger tensile force f is applied to leading sheave 7, thus the wearing and tearing substantially eliminated between leading sheave 7 and steel rope 8.
