Abstract
The utility model discloses a telescopic type cross supporting beam relating to the technical field of lifting mechanical equipment. The telescopic type cross supporting beam comprises a cross beam provided with multiple groups of lifting lugs, wherein each group of lifting lugs comprise two lifting rings which are positioned on the upper side and the lower side of the cross beam and are correspondingly arranged; the cross beam is provided with a main beam and telescopic beams embedded in the two ends of the main beam; the connecting parts of the main beam and the telescopic beams are provided with positioning pin shafts penetrating through the main beam and the telescopic beams. Compared with the prior art, the telescopic type cross supporting beam disclosed by the utility model has the advantages that the cross beam is provided with the main beam and the telescopic beams embedded in the two ends of the main beam, when goods with small lifting span are lifted, the need can be met only by using the main beam, so that the lifting weight is reduced and the lifting space is saved; and when the goods with large lifting span are lifted, the main beam and the telescopic beams are combined for use, the lengths of the telescopic beams extending out of the main beam can be adjusted and can form different lifting spans, so that the need for lifting the goods with multiple spans is met.
Description
Technical field
The utility model relates to elevator machinery equipment manufacturing technology field, especially a kind of telescopic bolster for lift cargo.
Background technology
Tradition hanging beam is normally installed with the hanger of multiple suspension Current Collector Sleaves on hanging beam, can meet the goods lifting of different spans, but when lifting in, hangs over the transverse pitch of steel rope on crane and the steel rope existence of Under-Slung Loads, cause goods to produce great moment of flexure to whole hanging beam, for guaranteeing the Strength Safety of hanging beam, the cross-sectional plane of hanging beam needs larger, the corresponding meeting of conducting oneself with dignity of whole hanging beam is very large, and the maximum of hanging beam lifting span differs greatly with minimum lifting span, in the time of the goods of the little span of lifting, hanging beam exceeds that to lift by crane the part of span idle, the deadweight of this part has increased hoisting weight, take lifting space.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of telescopic bolster that can regulate according to lifting span bolster span.
In order to address the above problem, the technical solution adopted in the utility model is: this telescopic bolster, comprise the crossbeam that is provided with many group hangers, and every group of hanger forms by being positioned at corresponding two suspension ring that arrange in the upper and lower both sides of described crossbeam; Described crossbeam has girder and is nested in the telescopic girder in described girder two ends, and the connecting portion of described girder and described telescopic girder is provided with the alignment pin through described girder and described telescopic girder.
In above-mentioned telescopic bolster technical scheme, technical scheme can also be more specifically: on described girder, be arranged at intervals with multiple connecting bores; One end of described telescopic girder is provided with at least one knock hole being communicated with described connecting bore, the other end be provided with at least one group described in hanger.
Further, the every group of hanger being positioned on described girder is all fixed in its upper and lower both sides, between middle two groups of hangers, be provided with an arc shape Zhu plate, between all the other adjacent each group of hangers, be provided with the 2nd arc shape Zhu plate, the two ends place that a described arc shape Zhu plate and described the 2nd arc shape Zhu plate are positioned at every group of hanger is provided with and adds strong Zhu plate.
Further, the every group of hanger being positioned on described telescopic girder is fixed on described telescopic girder by the otic placode that passes the upper and lower both sides of described telescopic girder.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, telescopic bolster comprises the crossbeam that is provided with many group hangers, and every group of hanger forms by being positioned at corresponding two suspension ring that arrange in the upper and lower both sides of crossbeam, on two suspension ring of same group of hanger, hangs respectively steel rope; When lifting cargo, hang over not relative the staggering of steel rope of steel rope on crane and Under-Slung Loads, the goods of lifting can not produce moment of flexure to bolster, and the cross-sectional plane of bolster can be much smaller than the cross-sectional plane of traditional hanging beam, conducts oneself with dignity corresponding also little a lot.
2, crossbeam has girder and is nested in the telescopic girder in girder two ends, the connecting portion of girder and telescopic girder is provided with the alignment pin through girder and telescopic girder, on girder, be arranged at intervals with multiple connecting bores, one end of telescopic girder is provided with at least one knock hole being communicated with connecting bore; The length that telescopic girder stretches out girder can regulate, and forms multiple different lifting span, meets the needs of multiple span lifting cargo.
3, in the time of the large goods of lifting span, by the use that combines of girder and telescopic girder; In the time of the little goods of lifting span, only use girder just can meet lifting needs, alleviate hoisting weight, space is lifted by crane in saving, and this unitized construction is simple, easy accessibility.
4, the every group of hanger being positioned on girder is all fixed in its upper and lower both sides, between middle two groups of hangers, be provided with an arc shape Zhu plate, between all the other adjacent each group of hangers, be provided with the 2nd arc shape Zhu plate, the two ends place that an arc shape Zhu plate and the 2nd arc shape Zhu plate are positioned at every group of hanger is provided with and adds strong Zhu plate; While reducing lifting cargo, the stress at hanger place, has increased intensity.

The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
The telescopic bolster of one as shown in Figure 1, comprise the crossbeam that six groups of hangers are housed, every group of hanger forms by being positioned at corresponding two suspension ring 5 that arrange in the upper and lower both sides of crossbeam, and crossbeam has girder 3 and is nested in the telescopic girder 1 in girder 3 two ends, is arranged at intervals with eight connecting bores 7 on girder 3; One end of telescopic girder 1 has a knock hole being communicated with connecting bore 7, and the other end is equipped with one group of hanger, and girder 3 is equipped with the alignment pin 2 through girder 3 and telescopic girder 1 with the connecting portion of telescopic girder 1; The every group of hanger being positioned on girder 3 is all welded thereon lower both sides by support plate, between middle two groups of hangers, be welded with an arc shape Zhu plate 6, between all the other adjacent each group of hangers, be welded with the 2nd arc shape Zhu plate 4, the two ends place that the one arc shape Zhu plate 6 and the 2nd arc shape Zhu plate 4 are positioned at every group of hanger is welded with and adds strong Zhu plate 8, as shown in Figure 2; The one group of hanger being positioned on telescopic girder 1 is welded on telescopic girder 1, as shown in Figure 3 by the otic placode 9 that passes telescopic girder both sides Shang Xia 1.
In the time of the little goods of lifting span, split out alignment pin 2, girder 3 is separated with telescopic girder 1, as shown in Figure 4, Figure 5; Only use girder 3 just can meet lifting needs, alleviated hoisting weight, save lifting space; In the time of the large goods of lifting span, by the use that combines of girder 3 and telescopic girder 1, the length that telescopic girder 1 stretches out girder 3 can regulate, and forms multiple different lifting span, meets the needs of multiple span lifting cargo; This unitized construction is simple, easy accessibility.
