Abstract
An embodiment of the utility model provides a vertical rotation connection structure, and relates to the field of bridge buildings. The vertical rotation connection structure comprises a plurality of steel wire ropes; as for a floating crane, when a cofferdam arrives at the destination, main hooks and auxiliary hooks of the floating crane are connected with the cofferdam through the steel wire ropes, a front positioning ship is connected with the cofferdam through the steel wire ropes, and the front positioning ship is located on the upper stream of the cofferdam.
Description
Technical field
The utility model relates to the bridge construction field, the structure that particularly a kind of vertical transfer connects.
Technical background
Along with the development of the construction industries such as highway, railway, deepwater foundation construction often can run in the large bridges of crossing over great river, lake in recent years, and Double-Wall Steel Boxed Cofferdam has been obtained application as a kind of water-bound that encloses of bridge deepwater foundation construction.And the intectate scar large-sized deep water foundation construction of tilting greatly is a technical barrier in bridge construction always, be total duration of engineering constraint or even the key technology factor that causes the engineering success or failure.
According to riverbed scar concrete condition, design and be applicable to riverbed and change the special-shaped sword bottoms weir of the height identical with its scar and utilize land construction advantage and facility, install and complete on the coast or in producer, then transport it into place, pier position and transfer.But, a urgent problem during how to the safe vertical transfer in cofferdam.
The utility model content
In view of this, the structure that the utility model embodiment provides a kind of vertical transfer to connect, can guarantee that steel cofferdam safety in the vertical transfer process is controlled.
The utility model embodiment also provides a kind of vertical transfer link structure, comprise many wire rope, crane barge is when arrival destination, cofferdam, the main hook of described crane barge, auxiliary hook are connected with described cofferdam by wire rope, and the prelocalization ship is connected with described cofferdam by wire rope, described forward location accommodation is in the upstream in described cofferdam.
Wherein, described vertical transfer syndeton also comprises rear station keeping ship, and described rear station keeping ship is connected with described cofferdam by wire rope, and described rear station keeping ship is positioned at the downstream in described cofferdam.
Wherein, described crane barge connects the side in cofferdam by wire rope.
The structure that the vertical transfer that utilizes the utility model embodiment to provide connects, can realize that the location of steel cofferdam in steel cofferdam vertical transfer process and safety are controlled, makes the whole vertical transfer of steel cofferdam that smooth construction is installed.
The accompanying drawing explanation
Figure 1 shows that the structural representation one that in the utility model embodiment, vertical transfer connects;
Figure 2 shows that the structural representation two that in the utility model embodiment, vertical transfer connects.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.
Better understand for the ease of those skilled in the art the method that vertical transfer that the utility model embodiment provides connects cofferdam.
Figure 1 shows that the structural representation one of the vertical transfer connection that the utility model embodiment provides.
Shown in Fig. 1, a kind of vertical transfer link structure, comprise many wire rope, crane barge 1 is in cofferdam 2 while arriving destination, the main hook 11 of described crane barge 1, auxiliary hook 12 are connected with described cofferdam 2 by wire rope, and prelocalization ship 3 is connected with described cofferdam 2 by wire rope, and described forward location ship 3 is positioned at the upstream in described cofferdam, rear station keeping ship 4 is connected with described cofferdam 2 by wire rope, and described rear station keeping ship 4 is positioned at the downstream in described cofferdam.
Corresponding to Fig. 1, a kind of vertical transfer that the utility model embodiment provides connects the method in cofferdam, comprising:
Step 101, by the cofferdam transportation by driving to destination, locate described cofferdam by crane barge, prelocalization ship and rear station keeping ship, described prelocalization accommodation is in the upstream in described cofferdam, described rear station keeping ship is positioned at the downstream in described cofferdam.
Step 102, the main hook by crane barge, auxiliary hook are controlled the lifting in cofferdam and transfer.
Step 103, control cofferdam processed by prelocalization ship and rear station keeping ship and be moved under the effect of external force to prevent cofferdam.
This method of attachment comprises two parts: a part is to control the connection of steel cofferdam vertical transfer speed, is being connected of steel cofferdam and major-minor suspender, the speed control steel cofferdam vertical transfer speed that promotes and transfer by the major-minor hook; A part is to prevent the steel cofferdam connection that (being mainly water currents) is moved under external force in the vertical transfer process, for steel cofferdam and front and back station keeping ship be connected and with being connected of crane barge, in the vertical transfer process, by the wire rope of connection is stressed, make steel cofferdam not affected by current and other external force to be subjected to displacement.
Figure 2 shows that the structural representation two of a kind of vertical transfer connection that the utility model embodiment provides.
As shown in Figure 2, the structure that provides a kind of vertical transfer to connect at another embodiment of the utility model, comprise many wire rope, crane barge 1 is in cofferdam 2 while arriving destination, the main hook 11 of described crane barge 1, auxiliary hook 12 are connected with described cofferdam 2 by wire rope, side and prelocalization ship 3 that crane barge 1 connects cofferdam 2 by wire rope are connected with described cofferdam 2 by wire rope, and described forward location ship 3 is positioned at the upstream in described cofferdam 2.
Corresponding to Fig. 2, a kind of vertical transfer that the utility model embodiment provides connects the method in cofferdam, comprising:
Step 201, by the cofferdam transportation by driving to destination, locate described cofferdam by the cat osseous system on crane barge, prelocalization ship and crane barge, described prelocalization accommodation is in the upstream in described cofferdam.
Step 202, the main hook by crane barge, auxiliary hook are controlled the lifting in cofferdam and transfer.
Step 203, control cofferdam by the anchor system on prelocalization ship and crane barge and be moved under the effect of external force to prevent cofferdam.
This method of attachment comprises two parts: a part is to control the connection of steel cofferdam vertical transfer speed, is being connected of steel cofferdam and major-minor suspender, the speed control steel cofferdam vertical transfer speed that promotes and transfer by the major-minor hook; A part is to prevent the steel cofferdam connection that (being mainly water currents) is moved under external force in the vertical transfer process, for steel cofferdam and front and back station keeping ship be connected and with being connected of crane barge, in the vertical transfer process, by the wire rope of connection is stressed, make steel cofferdam not affected by current and other external force to be subjected to displacement.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement etc., within all should being included in protection domain of the present utility model.
