3,058,189 JACKING APPARATUS FOR TUBULAR PHJES AND CAISSONS Eherhardt C. Rechtin, deceased, late of Beaumont, Tex, by The First National Bank of Beaumont, executor, Beaumont, Tex, assignor to Bethlehem Steel Company, a corporation of Pennsylvania Original application Dec. 27, 1956, Ser. No. 630,998, new Patent No. 2,969,648, dated Jan. 31, 1961. Divided and this application May 22, 1959, Ser. No. 815,152 11 Claims. (Cl. 24-263) This application is a division of an earlier filed copending application for Mobile Drilling Platform and Method of Operation, filed December 27, 1956, Serial No. 630,998, which latter application (now US. Patent 2,969,648) is a continuation-in-part of an earlier filed and then copending, but now abandoned, application for Mobile Drilling Platform and Method of Operation, filed July 26, 1955, Serial No. 524,518.
The subject of this invention is a jacking or gripping mechanism for exerting a longitudinal thrust on a tubular member such as a pile, caisson or the like. This jacking or gripping mechanism is particularly useful in association with mobile platforms employed in offshore operations such as, for example, drilling oil wells in marine locations. In such connection, the jacking or gripping mechanism can be utilized to exert a thrust on a pile or caisson whereby to lower and drive said pile or caisson into the marine floor, to extract and raise said pile or caisson from the marine floor, to lower or raise a submersible foundation secured to caissons or tubular members actuated by said jacking or gripping means, to secur an erating platform to driven piles, or for similar operations.
Briefly, the jacking or gripping mechanism comprises an annular yoke formed with upper and lower oppositely tapered conical sections, which yoke receives in its annulus a tubular member upon which the longitudinal thrust is to be exerted, upper and lower wedging means engageable respectively between the upper and lower conical sections of the yoke and the tubular members, positioning means to position selectively the upper or lower wedging means into operative engagement between the yoke and the pile thereby permitting selectively an upward or a downward thrust upon the tubular member, and means to raise or lower said yoke.
One of the objects of this invention is the provision of an improved jacking or gripping mechanism for selectively gripping, pushing and pulling the tubular member such as a pile or caisson.
Another object of this invention relates to the means for positioning selectively the upper or lower wedges in the yoke.
A further object of this invention is the provision of means to permit the wedge in the yoke to adjust to the eccentricity of the tubular member in the annulus of the yoke.
Other and further objects of this invention will be apparent during the course of the following description.
While the best embodiment of the invention known is herein described, said invention is capable of embodiment in many different forms, and the illustrated embodiment is, therefore, to be regarded only as typical, and the invention is not to be confined thereto.
Referring now to the drawings, in which like numerals represent like parts in the several views:
FIG. 1 represents a partial sectional View in elevation of this invention, showing the wedge positioner and annular yoke adjacent a tubular member such as the pile or caisson of U8. Patent 2,969,648.
FIG. 2 represents a view in plan of this invention, showing the annular yoke and wedge positioner and the tubular member gripped thereby.
FIG. 3 represents a section in plan, taken along the line 33 of FIG. 1, showing particularly the orientation of the air cylinders which actuate the wedge positioner.
FIG. 4 represents a section in elevation, taken along the line 44 of FIGS. 2 and 3, showing the annular yoke, one of the piston rods employed to raise, hold stationary, or lower the annular yoke relative to the foundation structure, and the centering guides and tubular member.
FIG. 5 represents a detail of the upper bracket assembly of the wedge positioner, with the spring omitted for purposes of clarity.
FIG. 6 represents a section in plan, taken along the line 66 of FIG. 1, showing in detail the lower bracket assembly of the wedge positioner with the spring omitted for purposes of clarity.
FIG. 7 represents a detail of the lower bracket assembly of the wedge positioner as viewed in elevation, with the spring omitted for purposes of clarity.
The gripping or jacking apparatus comprises annular yoke 49 with upwardly and outwardly tapered conical section 76 surmounting in vertically registering relationship a downwardly and outwardly tapered conical section 77. An upper flange 78, plates 79 and a lower flange 80' are also provided. Webs 81, located about the perimeter of annular yoke 49, are secured to conical sections 76 and 77, to plates 79, and to lower flange 80, thereby stiffening said annular yoke 49. Piston rods 55 extend through lower flange 80 and plates 79, and maybe secured thereto by stops or nuts 82 bearing against the upper and lower faces respectively of the said plates 79 and lower flange 80 whereby relative movement between piston rods 55 and annular yoke 49 is prevented.
Other details of this invention include stop rings 250 secured to pipe guides 218 and adapted to bear against collars 219, thus defining upper and lower limits of movement of said pipe guides 218 and preventing over-travel of the latter which might damage the system. The neutral position of pipe guides 218, wherein neither upper wedges 232 nor lower wedges 239 are in frictional engagement between annular yoke 49 and pile 11, is definable and maintainable by pins 251 insertable through pipe guides 218 to bear against collars 219 as shown in FIG. 1. Adequate centering of annular yoke 49 about pile 11 is provided for by securing inwardly extending guides 252 and 253 to conical sections 76 and 77, respectively, of said annular yoke 49. Following good engineering practice, valves 254 may be placed in lines 214 and 215 to isolate individual air cylinders without interfering with the operation of the other air cylinders.
Although the invention has been shown and described in considerable detail, it is not to be limited to the exact construction shown and described, but may include such substitutions, modifications or equivalents thereof as are embraced within the scope of the invention or as pointed out in the claims.
