Between subsea template direction peg pipe described in the utility model and stake pipe box in the cementing stopping ring seal structure the outer wall of direction peg pipe be positioned at sealed rubber ring below be provided with several guiding gussets around the direction peg pipe, the guiding gusset play the guiding role and protects the black box effect.
Between subsea template direction peg pipe described in the utility model and stake pipe box in the cementing stopping ring seal structure, the outer wall of direction peg pipe be positioned at sealed rubber ring above be provided with several guiding gussets around the direction peg pipe, the top of guiding gusset is seated in and plays stake pipe location on the pipe box horn mouth inclined-plane.
Cementing stopping ring seal structure is compared between the utility model and existing subsea template direction peg pipe and stake pipe box, has following advantage:
1, sealed rubber ring becomes bowl structure, and before putting into a pipe box, the diameter of its outer rim is greater than the diameter of a pipe box, after putting in the pipe box, outer rim is extruded, and forms interference fit with stake pipe box inwall, so that when above sealed rubber ring, injecting cement, can not reveal.
2, be provided with the guiding gusset in the above and below of sealed rubber ring, when sealed rubber ring with the direction peg pipe in the stake pipe box when mobile, the guiding gusset can effectively protect sealed rubber ring, prevents its distortion or is damaged.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model king-pile pipe box and direction peg pipe.
Fig. 2 is the partial enlarged drawing at Figure 1A place.
Fig. 3 is the structural representation of sealed rubber ring in the utility model.
Fig. 4 is the partial enlarged drawing at Figure 1B place.
The specific embodiment
Fig. 1, Fig. 2, Fig. 3, Fig. 4 show a more excellent embodiment of the present utility model.
Underwater drilling basal disc specification in the present embodiment is 2X2, design has three direction peg pipes 20, see also shown in Figure 1, direction peg pipe 20 coaxial being arranged in the pipe box 10, wherein the external diameter of direction peg pipe 20 is 762mm, and the internal diameter of stake pipe box 10 is 1078mm, and the gap of 158mm is arranged between stake pipe box and the stake pipe, in order to ensure the intensity of direction peg pipe 20, this gap must be filled with cement casting.As shown in Figure 2, be provided with cement baffle ring black box 30 in the bottom of fit at direction peg pipe 20 mutually with stake pipe box 10.As shown in Figure 3, cementing stopping ring black box 30 comprises sealed rubber ring 31, lower plate 32, train wheel bridge 33 and the lock bolt 34 of annular, wherein lower plate 32 covers are welded on the outside of direction peg pipe 20, and train wheel bridge 33 is positioned at the top of lower plate 32, clamp sealed rubber ring 31 by fastening bolt 34.Sealed rubber ring 31 is bowl structure, adopt the thick rubber glue ring processing and manufacturing of 20mm to form, Shao's formula hardness of sealed rubber ring 31 is 50～55 degree, the middle part of sealed rubber ring 31 is by two clamping plate 32,33 clamp, under the free state before being inserted in a pipe box 10, the external profile diameter D2 of sealed rubber ring 31 is slightly larger than the inside diameter D 1 of a pipe box 10, after direction peg pipe 20 is inserted in a pipe box, the outer rim of sealed rubber ring 31 is pressed against the center of a pipe box 10, shown in the dotted portion among Fig. 3, realize and an interference fit of pipe box 10 inwalls, after direction peg pipe 20 is in place, from the horn mouth injection cement of stake pipe box.
As shown in Figure 3, the diameter D3 of lower plate 32 is slightly less than the inside diameter D 1 of a pipe box 10, and when carrying out cementing, lower plate 32 bears most pressure, increases sealing effectiveness.
In addition, the weld seam of stake pipe box 10 inwalls is also handled through polishing, slides when moving down the weld seam damage sealed rubber ring of projection with direction peg pipe 20 to prevent sealed rubber ring 31 in stake pipe box 10.
In order when being lowered to direction peg pipe 20, effectively cementing seal stopper ring assembly 30 to be protected, on the outer wall of direction peg pipe 20, be provided with two- layer guiding gusset 40,50 up and down; 40 designs of first floor guiding gusset are below cementing seal stopper ring assembly 30; play guiding and 30 effects of protection cementing seal stopper ring assembly; second layer guiding gusset 50 is arranged on the top of cementing seal stopper ring assembly 30; at the direction peg pipe by after being put into the position; the top of this layer guiding gusset 50 is seated on the horn mouth inclined-plane of a pipe box 10; as shown in Figure 4, the depth of setting to direction peg pipe 20 positions.When sealed rubber ring 31 moved down in the stake pipe box with direction peg pipe 20, guiding gusset 40,50 can effectively protect sealed rubber ring 31, prevented its distortion or was damaged and cause sealing failure.
Between subsea template direction peg pipe in the present embodiment and stake pipe box in the cementing stopping ring seal structure, because sealed rubber ring 31 is bowl structure, before putting into a pipe box 10, the diameter of its outer rim is greater than the diameter of a pipe box, put in the pipe box 10 after, outer rim is extruded, form interference fit with stake pipe box 10 inwalls, and the strength support of lower plate 32 as sealed rubber ring arranged, when above sealed rubber ring 31, injecting cement, can not leak.
