The utility model provides a kind of rotation bridge of the nose that accommodation curve crane span structure is set, including more piece girder steel peace adapter, the flat turn connector connects two neighboring girder steel, the flat turn connector includes the female for being installed on a girder steel and the male connector for being installed on another girder steel, the male connector and female extend and carry out pin joint by rotary pin shaft relatively, the flat turn connector is divided into flat turn connector and lower flat turn connector, the upper flat turn connector and lower flat turn connector are separately connected the top and bottom of the girder steel, and the rotary shaft of the upper flat turn connector and lower flat turn connector is same rotary shaft.The rotation bridge of the nose that accommodation curve crane span structure provided by the utility model is set is mounted on bridge fabrication machine, so that girder steel is rotated using flat turn connector, bending is formed between adjacent girder steel, so as to which the bridge of the nose to be formed to the curve of a variety of curvature, meets the curved bridge construction requirement of multi-curvature, improve bridge construction efficiency.
Description
Technical field
The utility model is related to bridge construction apparatus field, more particularly to a kind of rotation bridge of the nose that accommodation curve crane span structure is set.
Background technology
Curved bridge is a kind of common bridge, since the structure stress of curved bridge calculates complicated, difficulty of design and construction
It is larger, easily there is the problems such as top plate, cracking in webs, box girder body climb shifting, cause Bridge Accidents, so curved bridge requires when building
Higher, bridge fabrication machine needs the curvature of accommodation curve bridge, is set up according to designed curvature section assembling.And not due to curved bridge
Same segment has different curvature, to need a kind of bridge fabrication machine that can set up multi-curvature curved bridge.
Utility model content
The purpose of this utility model is to provide a kind of rotation bridge of the noses that accommodation curve crane span structure is set, to solve the above problems.
The utility model provides a kind of rotation bridge of the nose that accommodation curve crane span structure is set, including more piece girder steel peace adapter, institute
It states flat turn connector and connects two neighboring girder steel, the flat turn connector includes being installed on the female of a girder steel and being installed on another girder steel
Male connector, the male connector and female are opposite to be extended and carries out pin joint by rotary pin shaft, and the flat turn connector is divided into flat turn and connects
Head and lower flat turn connector, the upper flat turn connector and lower flat turn connector are separately connected the top and bottom of the girder steel, it is described on
The rotary shaft of flat turn connector and lower flat turn connector is same rotary shaft.
Optionally, the rotation bridge of the nose that the accommodation curve crane span structure is set further includes the driving device of the driving girder steel rotation.
Optionally, the thickness of the male connector is 140-150 millimeters, and the thickness of the female is 160-170 millimeters.
Optionally, the girder steel includes multiple triangular structures.
The rotation bridge of the nose that accommodation curve crane span structure provided by the utility model is set is mounted on bridge fabrication machine, utilizes flat turn connector
So that girder steel is rotated, forms bending between adjacent girder steel, so as to which the bridge of the nose to be formed to the curve of a variety of curvature, meet multi-curvature
Curved bridge construction requirement, improve bridge construction efficiency.

Specific implementation mode
Below in conjunction with the drawings and specific embodiments to the utility model proposes accommodation curve crane span structure set the rotation bridge of the nose work
It is further described.According to following explanation, will be become apparent from feature the advantages of the utility model.It should be noted that attached drawing is equal
Non-accurate ratio is used using very simplified form and, only to convenient, lucidly aid illustration the utility model is real
Apply the purpose of example.
It please refers to Fig.1 and Fig. 2, the rotation bridge of the nose that accommodation curve crane span structure provided by the utility model is set is mounted on Bridge Erector
Girder both ends, including more piece girder steel (the first girder steel 1 and the second girder steel 2 for convenience of description, are only shown in Fig. 1 and Fig. 2) peace
Adapter, the flat turn connector connect the first girder steel 1 and the second girder steel 2, and the flat turn connector includes being mounted on the first girder steel 1
On male connector 5 and the second girder steel 2 on female 6, the male connector 5 and female 6 are opposite to be extended, and the male connector 5 and female 6
Pass through 7 pin joint of rotary pin shaft.The male connector 5 and female 6 can be rotated around rotary pin shaft 7, to change the first girder steel 1 and the
The angle of two girder steels 2.The flat turn connector is divided into flat turn connector 3 and lower flat turn connector 4, and the upper flat turn connector 3 connects institute
The upper end of the first girder steel 1 and the second girder steel 2 is stated, the lower flat turn connector 3 connects under first girder steel, 1 and second girder steel 2
The rotary shaft of end, the upper flat turn connector 3 and lower flat turn connector 4 is same rotary shaft, first girder steel, 1 and second girder steel 2
Top and bottom rotated simultaneously around rotary pin shaft 7, stability when enhancing the first girder steel 1 and the second girder steel 2 rotation.
The rotation bridge of the nose that the accommodation curve crane span structure is set further includes driving device, and the driving device is arranged in the upper of girder steel
Side, to drive girder steel to rotate.The driving device is preferably hydraulic cylinder.
The thickness of the male connector 5 is less than the thickness of the female 6, and male connector 5 and female 6 is facilitated to carry out pin joint.The male connector 5
Thickness be 140-150 millimeter, the thickness of the female 6 is 160-170 millimeters.Preferably, the thickness of the male connector 5
It it is 145 millimeters, the thickness of the female 6 is 165 millimeters.
Preferably, first girder steel, 1 and second girder steel 2 includes multiple triangular structures, have stronger steady
It is qualitative.
It is illustrated by taking two girder steels as an example in the present embodiment, it will be appreciated by persons skilled in the art that this practicality is new
The structure between the adjacent girder steel of any two in the rotation bridge of the nose that the accommodation curve crane span structure that type is provided is set is and the present embodiment
It is identical.
Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the scope of the utility model
Calmly, any change, the modification that the those of ordinary skill in the utility model field does according to the disclosure above content, belong to right and want
Seek the protection domain of book.
