Description
Technical field
The present invention relates to technical field of bridge construction, refer to it is a kind of fortune bridge tower staged waterborne for sleeping in that turning of large scale, large-tonnage, special-shaped bridge tower installed servicing unit of vertically turning particularly.
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, bridge tower integral hoisting technology just progressively embodies the efficient height, the characteristics of Functionality, quality and appealing design.Owing to receive the aviation condition restriction, the whole scene that is transported to of crouching of bridge tower general using boats and ships, this just need utilize large-scale floating crane that bridge tower is carried out the integral body lifting of vertically turning.Bridge tower or arch in light weight to some in the past, that size is little are excessively vertically turned, and angle is spent less than 90 because it is turned, thus can not be the staged base generally, and the base of turning is all fixed the good stability of turning with its basis.And turn for the large scale bridge tower on boats and ships, and should finally forward the technology of turning of plumbness to, must solve following 3 problems:
1, the how transverse shakiness of self-adaptive ship of base of turning;
2, the bridge tower center of gravity forwards precritical support system to and changes (for special-shaped bridge tower, because the barycentric coodinates error of calculation maybe be bigger, this point is particularly important) automatically;
3, turn base along with how moving voluntarily in the process of turning;
Therefore, design a kind of fortune bridge tower staged for sleeping in waterborne servicing unit of vertically turning its realistic meaning is arranged.
Summary of the invention
The object of the invention is exactly to solve the problem that the above-mentioned background technology proposes; A kind of installation of turning of not only satisfying bridge tower under complicated wave condition such as rivers or sea is provided, also can after simplification, be applicable to fortune bridge tower staged waterborne for sleeping in that turning of land large-scale component the installed servicing unit of vertically turning.
The objective of the invention is to realize like this: a kind of fortune bridge tower staged for sleeping in waterborne servicing unit of vertically turning; Comprise the conveying track that is used to transport horizontal bridge tower; Described conveying track is provided with thrustor, and thrustor comprises jack and the transportation slide block that is slidingly connected with conveying track, the base of jack and conveying track keying; The output of jack and the keying of transportation slide block; Be fixed with active force bearing with difference in height on the described transportation slide block and from the power bearing, said active force bearing is provided with the active movement free bearing, the active movement free bearing is provided with groove; The active force bearing passes through connecting rod and is connected from the power bearing; Saidly be provided with driven movable free bearing from the power bearing, driven movable free bearing is provided with groove, and the two ends, bottom of corresponding horizontal bridge tower are fixedly connected with active rotation hinge and the driven rotating hinge that is complementary with groove respectively.
In such scheme:
Said active force bearing also comprises hollow and open-topped Active support base, and the Active support base is fixedly installed on the transportation slide block, and the active movement free bearing is arranged in the Active support base.
Be equipped with initiatively elastic caoutchouc between described Active support base and the active movement free bearing, initiatively elastic caoutchouc has cushioning effect, can adapt to rocking of hull by assurance activity free bearing, thereby guarantees the bridge tower stability in the process of turning.
Describedly also comprise hollow and open-topped driven base for supporting from the power bearing, driven base for supporting is fixedly installed on the transportation slide block, and driven movable free bearing is arranged in the driven base for supporting.
Be equipped with driven elastic caoutchouc between described driven base for supporting and the driven movable free bearing, driven elastic caoutchouc has cushioning effect, can assurance activity free bearing adapts to rocking of hull, thereby guarantees the bridge tower stability in the process of turning.
Said connecting rod is length-adjustable expansion link, and design is when the bridge tower longer dimension, can satisfy turning of bridge tower through the length of regulating expansion link to carry out like this.
Among the present invention, the Active support base is lower than driven base for supporting, and the two formation has the staged box base of difference in height.
Utilization fortune bridge tower staged waterborne for sleeping in that the present invention the designed implementation step that servicing unit turns to horizontal bridge tower of vertically turning is:
1, on deck in ship structure, install the present invention, simultaneously at the two ends, bottom of bridge tower respectively fixedly active rotation cut with scissors and driven rotating hinge.
2, through the crane barge bridge tower of slinging the active rotation hinge of the bottom of bridge tower is dropped in the groove in the active movement free bearing.
3, begin bridge tower is turned through crane barge, rotate in the groove of active rotation hinge in the active movement free bearing when turning, turning for bridge tower provides pivot point.
When the driven rotating hinge of 4, treating bridge tower bottom turned to the groove in the driven movable free bearing, the support of bridge tower was converted into by active movement free bearing and driven movable free bearing together support.
5, subsequently, the jacking through jack promotes the active force bearing and moves forward, and then drives from the power bearing along with the active force bearing travels forward synchronously.
The invention has the advantages that:
1, the driven elastic caoutchouc of laying between active elastic caoutchouc of laying between Active support base and the active movement free bearing and driven base for supporting and the driven movable free bearing, can the self adaptation hull in length and breadth to rocking, guarantee that bridge tower does not rock with hull;
2, have the active force bearing of difference in height and from the setting of power bearing, the center of gravity that makes horizontal bridge tower in the time of can making the horizontal bridge tower of movement 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, the dismounting simple and fast, can repeat to have enough to meet the need the characteristics of use, not only satisfies the installation of turning of bridge tower under complicated wave condition such as rivers or sea, also can satisfy the installation of turning of land large-scale component after the simplification.
