The specific embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Fig. 1 ~ 4, the present invention mainly comprises fixing body 1, swings housing 3 and stationary housing 4, and fixing body 1 side is provided with positioning sleeve 2, by positioning sleeve 2 mast that is located by connecting.
Fixing body 1 is provided with a plurality of guide rail bolts 6, and a plurality of guide rail bolts 6 are arranged in order and form semicircular swinging guide rails.Swing housing 3 and be provided with semicircular swing guide groove 5, swing housing 3 and be slidably mounted in swinging guide rails by swinging guide groove 5.On fixing body 1, be bolted stationary housing 4.
Swing housing 3 both sides and be oppositely arranged two the first clamping cylinders 7, the piston rod front end of each the first clamping cylinder 7 connects first and clamps slips 8.Stationary housing 4 both sides are oppositely arranged two the second clamping cylinders 12, and the piston rod front end of each the second clamping cylinder 12 connects second and clamps slips 13.Two the first clamping cylinders 7 that are oppositely arranged are for clamping the male joint that is positioned at the drilling rod that swings housing 3, and two the second clamping cylinders 12 that are oppositely arranged are for clamping the female joint of the drilling rod that is positioned at stationary housing 4, for ensuing unloading is moved ready.
Swing 3 liang of upper lateral parts of housing and be respectively equipped with and on first, on buckle 9 and the first upper supporting plate 11, the first upper supporting plates 11, be rotationally connected first-handly 10, first-hand 10 other end fastenings are connected to buckle 9 on first.4 liang of upper lateral parts of stationary housing are respectively equipped with on second and are rotationally connected second-hand 15 on buckle 14 and the second upper supporting plate 16, the second upper supporting plates 16, and second-hand connects buckle 14 on second 15 other end fastenings.Before use, by open first-hand 10 and second-hand 15, the pin and box sub of drilling rod is packed in housing.Then by first-hand 10 and second-hand 15 fastenings, prevent that drilling rod from deviating from.
In described swing housing 3, be provided with the first gathering sill 17 for the first clamping slips 8 guiding, in stationary housing 4, be provided with the second gathering sill 18 for the second clamping slips 13 guiding.
Fixing body 1 both sides connect respectively an oscillating oil cylinder 19 by swinging bearing pin 20, and the piston rod front end connection of rotating of each oscillating oil cylinder 19 is arranged on the connection bearing pin 22 that swings housing 3 lower ends.Described oscillating oil cylinder 19 both sides are provided with baffle plate 21.Two oscillating oil cylinders 19 of fixing body 1 both sides promote to swing housing 3 and swing back and forth along semicircular swinging guide rails.
Operating principle of the present invention is: during work, and the two groups of clamping cylinders oil-feed respectively on stationary housing and swing housing, cylinder piston rod stretches out, and promotes slips and draws in toward center, clamps respectively the pin and box sub of drilling rod.Two groups of oscillating oil cylinder difference while oil inlet and oil returns, control two piston rods formation one and draw a contracting action, and force transmission, to the both sides that swing housing, causes swinging housing and passes through guide rail bolt along the swing guide groove circular motion of fixing body, and formation one unloading is moved.After first oscillating stroke completes, the clamping cylinder swinging on housing unclamps, and after swing housing return, the clamping cylinder swinging on housing continues to clamp, and oscillating oil cylinder drives swing housing to complete next oscillating stroke.So repeatedly, until the complete unloading of the screw thread of one group of tool joint open.After unloading completes, the clamping cylinder swinging on housing unclamps, and a drilling rod just can completely be dismantled and remove.
