Abstract
The utility model relates to a balance sling for an opening rope of a grab bucket, particularly relates to balance connection for the grab bucket and a gantry crane, and belongs to the technical field of crane equipment. The balance sling for the opening rope of the grab bucket mainly comprises an upper hanger, a lower hanger, a hanger pin, upper hanging rings, lower hanging rings, upper pins, and lower pins. The upper hanger and the lower hanger are connected in a hinged manner by the hanger pin. The upper hanging rings are connected to two ends of the upper hanger in a hinged manner by the upper pins. The lower hanging rings are connected to two ends of the lower hanger in a hinged manner by the lower pins. The balance sling for the opening rope of the grab bucket is simple, compact and reasonable in structure, so that lifting of the grab bucket is stable and materials are not easy to scatter. The service life of the opening rope is prolonged, and faults are reduced.
Description
Technical field
The utility model relates to a kind of grab bucket and opens and closes the rope balance sling, and the balance that specifically is used to grab bucket with the door machine is connected, and belongs to the crane facility technical field.
Background technology
In prior art; Because the difference in length that the switching rope of the switching rope of grab bucket and door machine produces in processing or wire rope handling; Produce difference about causing a machine when going up and down grab bucket through the switching rope, discontinuity causes the not steady of lifting cargo of grabbing bucket; Material spills easily, and also can shorten the service life of switching rope.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point; Thereby provide a kind of grab bucket to open and close the rope balance sling, on grab bucket and the door machine two open and close ropes all be at last transmit through this suspender stressed, thereby reach stress balance; Make the grab bucket lifting steadily; Material is difficult for spilling, and has increased the service life that opens and closes rope, has reduced fault.
According to the technical scheme that the utility model provides, grab bucket opens and closes the rope balance sling and mainly comprises over sling, following suspension bracket, suspension bracket bearing pin, upper lift ring, lower lift ring, upper pin and lower bearing pin, and said over sling is articulated and connected through the suspension bracket bearing pin with following suspension bracket.Said over sling two ends are through the upper pin upper lift ring that is articulated and connected, and said suspension bracket two ends down are through the lower bearing pin lower lift ring that is articulated and connected.
Said over sling is provided with middle baffle plate with following suspension bracket junction.
Be provided with overhead gage between said over sling and the upper lift ring.
Be provided with lower baffle plate between said suspension bracket down and the lower lift ring.
Compared with present technology the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Make the grab bucket lifting steadily, material is difficult for spilling; Increase the service life that opens and closes rope, reduced fault.

Fig. 2 is the utility model lateral plan.
Description of reference numerals: suspension bracket, 3-suspension bracket bearing pin, 4-upper lift ring, 5-lower lift ring, 6-upper pin, 7-lower bearing pin, 8-middle baffle plate, 9-overhead gage, 10-lower baffle plate under 1-over sling, the 2-.
The specific embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
Shown in Fig. 1 ~ 2, the utility model mainly comprises over sling 1, following suspension bracket 2, suspension bracket bearing pin 3, upper lift ring 4, lower lift ring 5, upper pin 6 and lower bearing pin 7, and said over sling 1 is articulated and connected through suspension bracket bearing pin 3 with following suspension bracket 2.Said over sling 1 two ends are through upper pin 6 upper lift ring 4 that is articulated and connected, and said suspension bracket 2 two ends down are through lower bearing pin 7 lower lift ring 5 that is articulated and connected.
Said over sling 1 is provided with middle baffle plate 8 with following suspension bracket 2 junctions, prevents that over sling 1 and following suspension bracket 2 from bumping on suspension bracket bearing pin 3.
Be provided with overhead gage 9 between said over sling 1 and the upper lift ring 4, prevent that upper lift ring 4 from producing to rock on over sling 1.
Be provided with lower baffle plate 10 between said down suspension bracket 2 and the lower lift ring 5, prevent that lower lift ring 5 from producing to rock on suspension bracket 2 down.
The principle of work of the utility model is: when work, the switching rope under the door machine is connected with upper lift ring 4, and the switching rope in the grab bucket is connected with lower lift ring 5.Because steel rope is long, in use be easy to generate and reverse, collide, so dividing equally, two upper lift rings 4 and two lower lift rings 5 are arranged, prevent to open and close between the rope bumping, and can prevent and reverse.
In use, if upper lift ring 4 both sides discontinuity make that because over sling 1 is to be articulated and connected with following suspension bracket 2, following suspension bracket 2 still kept balance when over sling 1 produced, the lower lift ring 5 on the following suspension bracket 2 also keeps balance.If lower lift ring 5 both sides discontinuity make that according to same reason, over sling 1 still kept balance when suspension bracket 2 generations were tilted down, the upper lift ring 4 on the over sling 1 is stressed even, guarantees the steady of lifting.
After the utility model is installed and since grab bucket and two in door machine open and close rope all be at last transmit through this suspender stressed, thereby reach stress balance.The lifting of grab bucket is more steady, and material is difficult for spilling, and has increased the service life that opens and closes rope, has reduced fault.
