Problems solved by technology
The inclination of the pile frame inverted by this type of inversion system has great limitations, especially limited by the profile of the pile frame, which cannot effectively reduce the overall towing height of the piling ship, thus greatly limiting the navigation capacity of the piling ship

Embodiment Construction
[0015] Now further illustrate how the present invention is implemented in conjunction with accompanying drawings:
[0016] Such as figure 1 As shown, the pile frame 7 is a truss structure, the pile frame 7 and the hull stern have a pile frame rear hinge point 7-1 and a pile frame rear hinge point hinge seat 8, the slideway 6 is fixed in the middle of the pile frame 7, and the variable hinge is temporarily supported The rod 5 is movably connected to the pile frame 7, one end of the luffing cylinder 4 is hinged to the slideway 6 (can slide in the slideway), the other end is hinged to the deck of the hull 10, and the bracket 9 is arranged on the bow deck;
[0017] The front hinge point member 1 of the pile frame is the front hinge point 1-1 of the pile frame. The frame 2 is symmetrical to the center line of the hull 10 and fixed in front of the luffing cylinder 4, the distance between the hinge point 2-1 at the top of the front hinge point support frame 2 and the rear hinge poi...

The invention discloses a horizontal inverted pile frame system for a large pile driving barge and belongs to the field of hoisting machinery. A pile frame front hinge point member and a pile frame front hinge point are designed on the pile frame structure, and coordinative operation of a luffing pulley group and support of a front hinge point support frame are utilized; when the pile frame is inverted until two pile frame front hinge points are respectively overlapped with hinge points on the pile frame front hinge point support frame, the overlapped hinge points are connected by a pin shaft, connection between pile frame rear hinge points and pile frame rear hinge point hinge seat is released; with two pile frame front hinge points of the pile frame as the center, the pile frame continuously slowly inclines to be horizontally arranged on a bracket and the pile frame front hinge point support frame under the action of the self gravity through the coordinative operation of a luffing steel wire rope pulley group system; the pile frame is safe, reliable and high in efficiency when the luffing pulley groups participates in frame inversion, and the height of the inverted pile frame is reduced to the greatest degree; and therefore, the navigable of the pile driving barge is effectively improved, and the stability in the process of towing the pile driving barge is obviously improved.
Description
technical field [0001] The invention relates to a horizontal horizontal inversion system for a pile frame of a large-scale piling ship, which belongs to the field of hoisting machinery. Background technique [0002] In the bridge construction in our country, piling ships are more and more widely used. However, for the construction of inland river bridges, due to the limitation of navigable height, large piling ships cannot enter, so that the superior resources cannot be used rationally. The navigability of a piling ship is mainly determined by the height of the pile frame when it is in a resting state. At present, as for the inversion system of the pile frame with a truss-shaped truss structure that is widely used, the pile frame mainly passes through the luffing cylinder and its movable hinge with the stern. Some pile frames are even inverted gradually by adjusting the height of the bracket. The inclination of the pile frame inverted by this type of inversion system is ver...
