Detailed Description
The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.
The embodiment of the invention discloses an automatic steel wire rope releasing device which comprises a limiting column 9, a first buoy 8, a second buoy 13 and a steel wire rope 7, wherein one end of the limiting column 9 is fixed on the inner side of a horizontal stay bar 11, the limiting column 9 is perpendicular to the horizontal stay bar 11, one end of the steel wire rope 7 is connected with a tug 6, the other end of the steel wire rope is a lute head 12 sleeved on the limiting column 9, the lute head 12 is provided with the second buoy 13, and the first buoy 8 is arranged between the lute head 12 and the joint of the steel wire rope 7 and the tug 6.
In this embodiment, the distance between the first buoy 8 and the lute head 12 is 3m-5 m. The first buoy 8 is in the range of 3m-5m, and the automatic releasing effect is best.
In this embodiment, the side wall of the first buoy 8 is fixedly connected with the steel wire rope 7.
In this embodiment, the second buoy 13 and the lute head 12 are connected by a binding rope 14.
In this embodiment, an included angle between the steel wire rope 7 and the limiting column 9 is α, and when α is greater than 90 °, the lute head 12 is released from the limiting column 9.
In this embodiment, the top of the jacket is provided with horizontal struts 11, and when the jacket 4 is laid down, the horizontal struts 11 are pulled transversely by the utility tug 6.
In this embodiment, lute head 12 is a rope loop formed by bending and knotting the other end of steel wire rope 7, and the rope loop is looped over limiting column 9, so as to realize the sleeve connection between lute head 12 and limiting column 9.
In this embodiment, before the jacket 4 is pulled and laid down, the horizontal brace 11 at the cabled walkway is welded with the limit column 9, then one end of the steel wire rope 7 is connected with the tug 6, the lute head 12 at the other end of the steel wire rope 7 is sleeved on the limit column 9, and the buoy is bound.
In this embodiment, in the process that the tug 6 pulls and lays down the jacket 4, the jacket 4 is changed from the vertical type to the horizontal type, and the horizontally welded limiting column 9 is changed from the horizontal type to the vertical type. As shown in fig. 6, when the included angle α between the steel wire rope 7 and the limiting column 9 is less than or equal to 90 °, the buoy can provide a vertical upward buoyancy after entering water, and when the comprehensive buoyancy of the first buoy 8 and the second buoy 13 is greater than the friction force between the lute head 12 of the steel wire rope 7 and the limiting column 9, the buoy can drive the lute head 12 of the steel wire rope 7 to slide upward on the limiting column 9 until the lute head 12 is completely detached from the limiting column 9, so that the jacket 4 continues to sink due to inertia, and the steel wire rope 7 and the lute head 12 float on the sea level under the effect of the buoyancy.
In order to realize the automatic release of the steel wire rope 7 during the dragging and falling process of the jacket 4, the following steps are carried out.
As shown in fig. 1, a scaffold is erected on the horizontal stay 11 at the cabled walkway on the side where the jacket 4 is planned to fall, one end of the prefabricated restraining column 9 is welded to the inner side of the middle position of the horizontal stay 11, and the restraining column 9 is ensured to be installed horizontally. The tug 6 is in place at the side of the jacket 4 planned to be laid down, one end of the steel wire rope 7 is connected with a dragging point on the tug 6, and the lute head 12 at the other end of the steel wire rope 7 is sleeved on the limiting column 9 (the steel wire rope 7 needs to be ensured to pass through the upper part of the horizontal support rod 11). Then, a first buoy 8 is firstly bound on a steel wire rope 7 within 3-5 m from the lute head 12, and a second buoy 13 is hung at the most end part of the lute head 12 through a binding rope 14.
After the jacket 4 is subjected to mud discharging, internal cutting and single-side mud discharging in the underwater steel pile 3 as shown in the figure 2, the tug boat 6 starts to slowly tighten the steel wire rope 7 to drag and lay down the jacket 4. In the process of falling, after the inclination angle of the jacket 4 is increased, the first buoy 8 and the second buoy 13 enter water successively to provide vertical upward buoyancy for the steel wire rope 7 and the lute head 12. Meanwhile, the included angle alpha between the steel wire rope 7 and the limiting column 9 is reduced from large to small.
As shown in fig. 3, as the jacket 4 continues to incline, when the included angle α between the steel wire rope 7 and the limiting column 9 is smaller than or equal to 90 °, and the buoyancy provided by the first buoy 8 and the second buoy 13 is larger than the friction between the lute head 12 and the limiting column 9, the first buoy 8 and the second buoy 13 drive the steel wire rope 7 and the lute head 12 to slide upwards until the steel wire rope 7 and the lute head 12 are completely released from the limiting column 9.
As shown in fig. 4, after the steel wire rope 7 and the lute head 12 are completely released from the jacket 4, the jacket 4 continues to sink due to inertia, and the steel wire rope 7 and the lute head 12 float on the sea surface under the buoyancy of the first buoy 8 and the second buoy 13.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. The equivalent substitution or change made by the technical personnel in the technical field on the basis of the invention is all within the protection scope of the invention. The protection scope of the invention is subject to the claims.
