Detailed description of the invention
This burnisher being used for deep-sea marine riser comprises central tube body 1, inner sleeve 2 and outer sleeve 3.Central tube body 1 is provided with the shaft shoulder 4; The central tube body 1 of the shaft shoulder 4 both sides is provided with inner sleeve 2 by symmetrically arranged bearing 5.Inner sleeve 2 appearance is circumferentially evenly equipped with 4 inner sleeve rib blocks 6, and the inner sleeve 2 between inner sleeve rib block 6 is circumferentially provided with inner sleeve groove 7; The termination, one end of inner sleeve groove 7 is shutoff shape.
The end face of inner sleeve 2 one end is provided with upper end cover 10 by Upper gasket 8 and clamping bolt 9, the end face of inner sleeve 2 other end is provided with bottom end cover 12 by lower gasket 11 and clamping bolt 9.The object of upper end cover 10 and bottom end cover 12 is to bearing 5 fixations.Upper end cover 10 diameter is greater than inner sleeve 2 diameter, the diameter of bottom end cover 12 and inner sleeve 2 equal diameters; Upper end cover 10 and be provided with sealing ring 13 between bottom end cover 12 and central tube body 1.
Outer sleeve 3 is equipped with in the circumference side of inner sleeve 2, and outer sleeve 3 is made up of baffle ring 14 and outer sleeve body 15, and outer sleeve body 15 one end is fixed with baffle ring 14; Outer sleeve body 15 be circumferentially evenly equipped with multiple outer sleeve rib block 16.Baffle ring 14 endoporus of outer sleeve 3 circumferentially interval shape is provided with the outer sleeve block 17 corresponding with the inner sleeve groove 7 of inner sleeve 2, baffle ring 14 endoporus between outer sleeve block 17 circumferentially interval shape is provided with the outer sleeve inside groove 18 corresponding with the inner sleeve rib block 6 of inner sleeve 2, between outer sleeve 3 with inner sleeve 2 by between inner sleeve groove 7 with outer sleeve block 17 and inner sleeve rib block 6 be interconnected with coordinating between outer sleeve inside groove 18; Realize the assembling between outer sleeve 3 and inner sleeve 2 thus, and coordinating by inner sleeve groove 7 termination of outer sleeve block 17 and shutoff shape, prevent mutual slippage between outer sleeve 3 and inner sleeve 2.
Inner sleeve 2 between outer sleeve 3 and upper end cover 10 is provided with and splits ring 19, the inner sleeve 2 of segmentation ring 19 both sides is provided with wiper ring A21 and wiper ring B22 respectively by symmetrically arranged back-up ring 20.
This be used for the segmentation ring 19 of the burnisher of deep-sea marine riser, back-up ring 20, wiper ring A21 and wiper ring B22 endoporus be circumferentially respectively arranged with the assembling projection corresponding with the inner sleeve groove 7 of inner sleeve 2, the endoporus of segmentation ring 19, back-up ring 20, wiper ring A21 and wiper ring B22 between assembling projection is circumferentially respectively arranged with the assembling groove corresponding with the inner sleeve rib block 6 of inner sleeve 2; Segmentation ring 19, back-up ring 20, wiper ring A21 and wiper ring B22 locate (not shown) respectively by assembling projection mutually with coordinating between inner sleeve groove 7 and between assembling groove with inner sleeve rib block 6, realize segmentation ring 19, back-up ring 20, wiper ring A21 and the assembling of wiper ring B22 on inner sleeve 2 thus.Wiper ring A21 and wiper ring B22 is circumferentially interruption-like is respectively provided with cleaning brush 23; Cleaning brush 23 is made up of brush teeth bunch block.
When this is used for the burnisher work of deep-sea marine riser, outer sleeve 3 and inner sleeve 2 move up and down with central tube body 1, in this course, due between outer sleeve 3 with inner sleeve 2 by between inner sleeve groove 7 with outer sleeve block 17 and inner sleeve rib block 6 be mutually slidably connected with coordinating between outer sleeve inside groove 18; Therefore outer sleeve 3 can slide up and down in inner sleeve groove 7; And then wiper ring A21 and wiper ring B22 is also slided up and down in inner sleeve groove 7, realize the cleaning purpose to marine riser thus.If once there is card group phenomenon in wiper ring A21 and wiper ring B22, because inner sleeve 2 is arranged on central tube body 1 by symmetrically arranged bearing 5, therefore inner sleeve 2 can do corresponding rotation, and then drive segmentation ring 19, back-up ring 20, wiper ring A21 and wiper ring B22 to rotate, thus avoid card group point.
This is used in the burnisher course of work of deep-sea marine riser, outer sleeve rib block 16 pairs of marine risers also can play certain catharsis, and because outer sleeve rib block 16 external diameter is slightly less than marine riser internal diameter, so the damage of outer sleeve rib block 16 pairs of marine riser inwalls effectively can be avoided; Back-up ring 20 can play a protective effect to the cleaning brush 23 on wiper ring A21 and wiper ring B22 respectively, and collaborative cleaning brush 23 pairs of marine riser inwalls clean, thus carries out omnibearing clean to marine riser inwall, and avoids the damage to marine riser inwall.
This burnisher being used for deep-sea marine riser have structure simple, be convenient to dismounting and maintenance, feature that security performance is high, when solving the work of traditional marine riser burnisher, all adopt scraper to carry out clean marine riser inwall foreign material thus clean marine riser inwall, easily damage is caused to marine riser inwall, be not suitable for the problem that marine riser is clean.Have cleaning efficiency high, tool reliability is high simultaneously, and the adaptable feature in down-hole, has good economic benefit and dissemination; Be specially adapted to the clean use of deep-sea marine riser.
Above-described embodiment is only the description carried out the preferred embodiment of the present invention; not design of the present invention and scope are limited; under the prerequisite not departing from design philosophy of the present invention; the various distortion that in this area, engineers and technicians make technical scheme of the present invention and improvement; protection scope of the present invention all should be fallen into; the technology contents of request protection of the present invention, all records in detail in the claims.
