Abstract
The utility model discloses a flexible hinge which comprises a lower basin body, an upper basin body, a rubber pad and a micro rotation plate, wherein, the radial size of the outer wall of the lower basin body is smaller than that of the side wall of the basin bottom of the lower basin body; the outer wall of the lower basin body is drum-shaped; partial outer wall of the lower basin body is in micro-rotation tight matching with the partial inner wall of the upper basin body; the rubber pad and the micro rotation plate are sequentially adhered between the inner bottom of the lower basin body and the inner bottom of the upper basin body; the micro rotation plate is in micro-rotation tight matching with the inner wall of the mouth of the lower basin body through the drum-shaped outer surface of the lower part of the micro rotation plate; and the upper surface of the micro rotation plate is in slide contact with the inner bottom of the upper basin body. The flexible hinge is mainly used for a large-scale shipbuilding gantry crane, the main beam and the flexible legs of the gantry crane are in flexible connection, and the stress of the supporting legs of the gantry crane is improved. Therefore, the flexible hinge has the advantages of compact and reasonable structure, good complete machine steel structure, and excellent bearing capacity of the supporting legs.
Description
Technical field
The utility model relates to a kind of link, particularly relates to a kind of flexible hinge.
Background technique
Large shipbuilding straddle truck span is big, lifting altitude is high; The weight of its steel structure accounts for 80%～90% of whole straddle truck weight; If the supporting leg of straddle truck both sides all adopts and the rigidly connected rigidity leg of girder structure; The large deviation that big moment of flexure of bearing in the time of can working because of straddle truck so and manufacturing and installation possibly exist makes the stressed bad of supporting leg, and the weight of complete machine also can rise thereupon; And if straddle truck one side adopts and the rigidly connected rigidity leg of girder structure; Opposite side adopts the flexible leg structure that flexibly connects with girder; Then not only can guarantee the relatively stable of straddle truck structure; And can dissolve deflection that unfavorable factors such as big moment of flexure, large deviation bring the complete machine steel structure, reverse and additional moment, improve the stressed of supporting leg.
The model utility content
The purpose of the utility model provides a kind of flexible hinge, with girder and the flexible leg that flexibly connects straddle truck, improves the stressed of straddle truck supporting leg.
The purpose of the utility model realizes through following technological scheme:
A kind of flexible hinge; Comprise following basin body, go up basin body, rubber pad, little rotor plate; The radial dimension of said basin body outer wall down is less than the radial dimension of its basin downside wall; Said down basin body outer wall is cydariform, and the part outer wall of said basin body down and said tight cooperation of the little rotation of part inwall of going up basin body are close to successively between the interior end to the interior end of last basin body of said basin body down and are provided with rubber pad and little rotor plate; Said little rotor plate is through the cydariform outer surface and said basin mouth inwall tight cooperation of little rotation of basin body down, the upper surface of said little rotor plate and said sliding contact of the interior end of going up basin body of its underpart.
Preferably, teflon slide plate and the said interior end sliding contact of going up basin body of said little rotor plate through being arranged on its upper surface.
Preferably, said rubber pad is the neoprene pad.
Preferably, be provided with seal ring between the bottom of cydariform outer surface and rubber pad on said little rotor plate.
Preferably, be respectively arranged with protruding joint on the outer bottom of said upward basin body and following basin body.
Preferably, the gyration center of above basin body is that the center is uniformly distributed with and is provided with plural hanger on the said outer wall of going up basin body.
The utility model places down the compressibility of the rubber pad in the basin body through utilization; Little relatively rotation of little rotor plate and following basin body basin mouth inwall; And down little relatively rotation of basin body and last basin body, the Force Optimal balance of the member of having realized being connected with following basin body with last basin body has been dissolved deflection that unfavorable factors such as big moment of flexure, large deviation bring whole straddle truck steel structure, has been reversed and additional moment; Improved the stressed of supporting leg, and the utility model compact structure, reasonable.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the flexibility hinge of the utility model.
Among the figure: 1, following basin body; 2, go up basin body; 3, rubber pad; 4, little rotor plate; 5, teflon slide plate; 6, seal ring; 7, hanger.
Embodiment
As shown in Figure 1; The flexibility hinge of the utility model; Comprise following basin body 1, go up basin body 2, rubber pad 3 and little rotor plate 4, the radial dimension of said basin body 1 outer wall down is less than the radial dimension of its basin downside wall, and said basin body 1 outer wall down is cydariform; The part outer wall of said basin body 1 down and said tight cooperation of the little rotation of part inwall of going up basin body 2; Be close to successively between the interior end to the interior end of last basin body 2 of said down basin body 1 and be provided with rubber pad 3 and little rotor plate 4, said little rotor plate 4 is through cydariform outer surface and said basin mouth inwall tight cooperation of little rotation of basin body 1 down, the upper surface of said little rotor plate 4 and the said upward sliding contact of the interior end of basin body 2 of its underpart.
Preferably, the teflon slide plate 5 and said interior end sliding contact of going up basin body 2 of said little rotor plate 4 through being arranged on its upper surface.
Preferably, said rubber pad 3 is the neoprene pad.
Preferably, the bottom of cydariform outer surface and 3 of rubber pads are provided with seal ring 6 on said little rotor plate 4.
Preferably, be respectively arranged with protruding joint on the outer bottom of said basin body 1 down and last basin body 2.
Preferably, the gyration center of above basin body 2 is that the center is uniformly distributed with and is provided with plural hanger 7 on the said outer wall of going up basin body 2.
The utility model is mainly used in the large shipbuilding straddle truck, has compact structure, reasonable, the stressed good advantage of complete machine steel structure and supporting leg.
