Description
Technical field
The present invention relates to technical field of bridge construction, refer to particularly it is a kind of waterborne sleeping fortune bridge tower staged that turning of large scale, large-tonnage, special-shaped bridge tower installed servicing unit of vertically turning.
Background technology
At present, bridge bridge tower lifting is mainly formed by the lifting of crane barge merogenesis, welding coupling, and along with the development of bridge technology, it is high that bridge tower integral hoisting technique just progressively embodies efficiency, the feature of Functionality, quality and appealing design.Owing to being subject to aviation condition restriction, the sleeping scene that is transported to of bridge tower general using boats and ships entirety, this just need to utilize large-scale floating crane to carry out the entirety lifting of vertically turning to bridge tower.Bridge tower or arch lightweight to some, that size is little were excessively vertically turned in the past, because its angle of turning is less than 90 degree, thus can not be generally staged base, and turn base and its basis all fix, the good stability of turning.And turn for the large scale bridge tower on boats and ships, and should finally forward the technique of turning of plumbness to, must solve following 3 problems:
1, the how transverse shakiness of self-adaptive ship of base of turning;
2, bridge tower center of gravity forwards precritical support system to and automatically changes (for special-shaped bridge tower, because barycentric coodinates error of calculation may be larger, this point is particularly important);
3, turn base along with automatic moving how in the process of turning;
Therefore, a kind of sleeping fortune bridge tower staged waterborne of design servicing unit of vertically turning has its realistic meaning.
Summary of the invention
Object of the present invention is exactly to solve the problem that above-mentioned background technology proposes, provide a kind of installations of turning that not only meets bridge tower under rivers or the complicated wave condition such as marine, the waterborne sleeping fortune bridge tower staged that also can be applicable to the installation of turning of land large-scale component after the simplification servicing unit of vertically turning.
The object of the present invention is achieved like this: a kind of sleeping fortune bridge tower staged waterborne servicing unit of vertically turning, comprise the conveying track for transporting horizontal bridge tower, described conveying track is provided with thrustor, the transportation slide block that thrustor comprises jack and is slidably connected with conveying track, the base of jack and conveying track keying, the output of jack and the keying of transportation slide block, on described transportation slide block, be fixed with and there is the active force bearing of difference in height and from power bearing, described active force bearing is provided with active movement free bearing, active movement free bearing is provided with groove, active force bearing by connecting rod be connected from power bearing, describedly be provided with driven movable free bearing from power bearing, driven movable free bearing is provided with groove, the two ends, bottom of corresponding horizontal bridge tower are fixedly connected with respectively the active rotation hinge and the driven rotating hinge that match with groove.
In such scheme:
Described active force bearing also comprises hollow and open-topped active base for supporting, and initiatively base for supporting is fixedly installed on transportation slide block, and active movement free bearing is arranged in active base for supporting.
Between described active base for supporting and active movement free bearing, be equipped with initiatively elastic caoutchouc, initiatively elastic caoutchouc has cushioning effect, can adapt to rocking of hull by assurance activity free bearing, thereby guarantee the stability that bridge tower is turned in process.
Described also comprises hollow and open-topped driven base for supporting from power bearing, and driven base for supporting is fixedly installed on transportation slide block, and driven movable free bearing is arranged in driven base for supporting.
Between described driven base for supporting and driven movable free bearing, be equipped with driven elastic caoutchouc, driven elastic caoutchouc has cushioning effect, can adapt to rocking of hull by assurance activity free bearing, thereby guarantee the stability that bridge tower is turned in process.
Described connecting rod is length-adjustable expansion link, and design is that the length by adjustable telescopic rod can meet turning of bridge tower and carries out in the time of bridge tower longer dimension like this.
In the present invention, initiatively base for supporting is lower than driven base for supporting, and the two formation has the staged box base of difference in height.
Implementation step that servicing unit turns to horizontal bridge tower is to use the present invention designed waterborne sleeping fortune bridge tower staged vertically to turn:
1, in deck in ship structure, install the present invention, fix respectively active rotation hinge and driven rotating hinge simultaneously at the two ends, bottom of bridge tower.
2, by the crane barge bridge tower of slinging, the active rotation hinge of the bottom of bridge tower is dropped in the groove in active movement free bearing.
3, start bridge tower to turn by crane barge, while turning, active rotation is cut with scissors in the groove in active movement free bearing and is rotated, and turns pivot point is provided for bridge tower.
4, in the time that the driven rotating hinge of bridge tower bottom turns to the groove in driven movable free bearing, the support of bridge tower is converted into by active movement free bearing and driven movable free bearing and jointly supports.
5, subsequently, promote active force bearing by the jacking of jack and move forward, and then drive from power bearing along with active force bearing synchronously travels forward.
The invention has the advantages that:
1, the driven elastic caoutchouc of laying between the active elastic caoutchouc of initiatively laying between base for supporting and active movement free bearing and driven base for supporting and driven movable free bearing, vertical transverse shakiness that can self adaptation hull, guarantees that bridge tower does not rock with hull;
2, there is the active force bearing of difference in height and the setting from power bearing, the center of gravity that makes horizontal bridge tower can make the horizontal bridge tower of movement time all the time before run-on point, thereby guarantee that horizontal bridge tower can unexpected rollover out of control;
3, the special construction of rotating hinge and the movable free bearing that cooperatively interacts design, has guaranteed the convenience that the present invention installs, and bridge tower is turned flexibly, and structure partial intensity is firm.
That the present invention has is easy for installation, dismounting simple and fast, can repeat the feature that turnover is used, and not only meets the installation of turning of bridge tower under rivers or the complicated wave condition such as marine, also can meet the installation of turning of land large-scale component after simplification.
