The connecting line of the fixed eye plate 5 and the supporting base 1 and the edge line of the supporting base 1 are obliquely arranged.
Example 2
The embodiment provides an in-situ transverse moving and floating method for a ship tail fin structure, which comprises the following steps:
the method comprises the steps that before a ship tail fin structure is carried, an in-situ transverse moving floating device is arranged at a stern supporting position, a supporting base 1 is welded on a dock ground embedded part, a fixed pipe column 8 on a supporting pipe base 10 is embedded into a fixed sleeve 3, and the fixed pipe column penetrates through a fixed eye plate 5 and a guide eye plate 7 through a connecting shaft pin 6. At this time, the supporting tube base 10 and the fixed tube column 8 are in a suspended state due to the acting force of the jacking spring.
And step two, the whole transverse moving and floating device is in a compressed state by ballasting 5 tons of ballast iron on the base of the supporting tube, and a bolt penetrates through a fixed pipe column 8 and a locking pin hole 9 on the side surface of the fixed sleeve 3 to ensure that the whole jacking spring is kept in a compressed state, and at the moment, the ballast iron is lifted away.
And step three, subtracting the height of the supporting base 1 after being ballasted by the load from the ground to the outer plate according to the theoretical height corresponding to the supporting position, namely 1.2 meters, and then subtracting the height of the high supporting pipe 14 from the top to the outer plate, which is required to be provided with the piers, from 0.3 meter, so as to obtain the height value which is required to be selected by the high supporting pipe 14. Because the total jacking force of the four jacking springs 2 is 4 tons, the total weight of the high supporting tube 14 which can be placed on the four jacking springs is controlled within 3.7 tons. If a high support tube 14 having a wall thickness of 10 mm and a diameter of 990 mm is used, the maximum height of the high support tube 14 should be no greater than 15 m. An optional high support tube 14 is welded to the upper surface of the support tube base 10. At the moment, the supporting state of the transverse moving and floating device is finished, and the transverse moving and floating device is arranged to control the distance of 4.3 meters between the front and the back of the two supports.
And step four, placing conventional placing piers at the top of the high support pipe 14, hoisting the hull structure of the tail fin part to be ballasted to a corresponding support position, and floating and undocking the ship after the ship is built.
And step five, after the ship is built and before the ship is about to float and come out of dock, one end of a traction steel wire rope penetrates through the base fixed pulley 4 and the high-support fixed pulley 11, the end part of the traction steel wire rope and the steel wire rope eye plate 12 are fixed, and the other end of the traction steel wire rope is connected with a winch. The locking pins in the locking pin holes 9 are removed while the support bed remains compressed as the hull is ballasted above the high support tubes 14.
Step six, after the ship floats, the whole support loses ballast force at the moment, because of the jacking acting force of the jacking spring 2, the upper part of the whole self-inverting tubular support base comprises the support tube base 10 and the fixed tubular column 8, the combination body comprising the base guide eye plate 7 generates vertical lifting along the oval hole of the base guide eye plate 7, and because the depth of the fixed sleeve 3 is 220 mm, and the oval guide stroke of the guide eye plate 7 is 500 mm. The fixed pipe string 8 can thus be disconnected from the fixed casing 3, but the high support pipe 14 does not topple over at this time due to the traction force generated by the winch connecting wire rope. The high support can be gradually and directionally inclined by continuously conveying the steel wire rope through the winch and the pressing and supporting plate corresponding to the inside of the high support pipe at the position of the triangular support frame 13. Since the tripod 13 is seated at the ground. Because the fixed eye plate 5 and the guide eye plate 7 have an angle of 8 degrees in the horizontal direction, the parallel distance of 0.6 meter per 4.3 meters can be generated between the high support pipes 14 after the high support pipes are inclined, so that the front high support pipe 14 and the rear high support pipe 14 cannot collide with each other.
And 7, as shown in the fourth figure, the ship is gradually subjected to transverse deviation after the high support pipe 14 is toppled, so that undocking is realized, and the high support pipe 14 is toppled under the controllable state through the acting force of the self-toppling pipe type support pipe seat and the steel wire rope, so that the tail fin of the ship in the process of docking is not limited by support.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
