Further, described bearing locating rack comprises coaxial the first locating rack and the second locating rack being sleeved on fixed muffle on hollow gyroaxis and fixed muffle two ends respectively; Described first locating rack and be respectively equipped with seal between the second locating rack and hollow gyroaxis.
Further, described seal is the exoskeletal rubber seal of J type.
Further, described bearing locating rack and rotary reducer are equipped with hanger.
Further, described bearing is double-row conical bearing.
Further, described oil inlet and oil return passage is provided with free flow coupling near the side of clamping cylinder.
Further, the output shaft of described rotary reducer and hollow gyroaxis be arranged in parallel.
The advantage that the invention has and good effect are:
1) rotary reducer can drive rotary positioning frame 360 degree rotation, and then clamping cylinder rotary positioning frame being used for clamp drilling pipe also can 360 degree of rotations, and dismounting petroleum drill pipe operating efficiency is high.
2) rotary reducer drives gyroaxis travelling gear to rotate, and due to bearing locating rack being provided with bearing, therefore, stability of rotation is smooth and easy, and is provided with seal between bearing locating rack and hollow gyroaxis, working stability, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the invention.
Fig. 2 is the sectional view of Fig. 1.
Detailed description of the invention
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
A kind of 360 degree of revolution impact tongs, as depicted in figs. 1 and 2, the clamping clip 6 that extension bar 5 front end comprising two clamping cylinders 4 that extension bar 5 on rotary support mechanism 1, rotary reducer 2, rotary positioning frame 3 and rotary positioning frame 3 is oppositely arranged and two clamping cylinders 4 is equipped with; Described rotary support mechanism 1 comprises the gyroaxis travelling gear 8 of coaxial setting outside hollow gyroaxis 7 and hollow gyroaxis 7 and is sleeved on the bearing locating rack 10 of hollow gyroaxis 7 and the reductor locating rack 11 of bearing locating rack 10 lower end setting by bearing 9; Described hollow gyroaxis 7 sidewall is provided with to the oil inlet and oil return passage 12 of clamping cylinder 4 oil inlet and oil return; Described gyroaxis travelling gear 8 is arranged in the cavity 13 of bearing locating rack 10; Seal 14 is provided with between described bearing locating rack 10 and hollow gyroaxis 7; Described rotary reducer 2 is arranged on reductor locating rack 11, and its output shaft 15 end is provided with speed reducer drive gear 16; Described reductor locating rack 11 is provided with the idle wheel 17 simultaneously engaged with gyroaxis travelling gear 8 and speed reducer drive gear 16.
Wherein, described bearing locating rack 10 comprises coaxial the first locating rack 19 and the second locating rack 20 being sleeved on fixed muffle 18 on hollow gyroaxis 7 and fixed muffle 18 two ends respectively; Described first locating rack 19 and be respectively equipped with seal 14 between the second locating rack 20 and hollow gyroaxis 7.
Wherein, described seal 14 is the exoskeletal rubber seal of J type, good sealing effect, long service life, work stable for a long time under being adapted at this operating mode.
Wherein, on described bearing locating rack 10 and rotary reducer, 2 are equipped with hanger 21, convenient lifting, convenient and strength-saving when producing assembling or transfer transport.
Wherein, described bearing 9 is double-row conical bearing, reliable and stable, and work stable for a long time under being adapted at this operating mode, without the need to special maintenance.
Wherein, described oil inlet and oil return passage 12 is provided with free flow coupling 22 near the side of clamping cylinder 4, the oil inlet and oil return pipe be connected on two clamping cylinders 4 is connected with the free flow coupling 22 on drainback passage 12 respectively, like this, when hollow gyroaxis 7 rotates, same energy, to clamping cylinder 4 fuel feeding, solves external oil feed line and cannot adapt to 360 degree of pivotal technical barriers.
Wherein, the output shaft 15 of described rotary reducer 2 be arranged in parallel with hollow gyroaxis 7.Compact conformation, rationally distributed.
When carrying out dismounting drilling pipe, first stretch out with the extension bar 5 rotary positioning frame 3 being oppositely arranged two clamping cylinders 4, the clamping clip 6 of its front end clamps drilling tool.Then, after starting rotary reducer 2, the speed reducer drive gear 16 that output shaft 15 front end of rotary reducer 2 is arranged directly drives idle wheel 17 to rotate, and then drive gyroaxis travelling gear 8 to rotate by idle wheel 17, thus achieve drive hollow gyroaxis 7 rotate, two clamping cylinders 4 in hollow gyroaxis 7 front end, also namely along with rotary positioning frame 3 turns round, drive drilling pipe rotation, complete the disassemble and assemble work of drilling pipe.
Because rotary reducer can drive rotary positioning frame 360 degree rotation, and then the clamping cylinder 4 rotary positioning frame 3 being used for clamp drilling pipe also can 360 degree rotations, and therefore, reliably, production efficiency is high for dismounting petroleum drill pipe working stability.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
