The size of hydraulic coupling controls the torque that links closely when adapting to the tense-lax button of small space bolt and nut, and can be linked closely by control
Size.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions：
Cylinder body, piston rod and jaw, institute are installed in a kind of hollow type hydraulic pressure spinner, including housing, the housing
State piston rod to be provided with cylinder body in piston, the cylinder body provided with pipeline, one end of the pipeline connects entering for piston two ends
Oil-out, the other end connection of the pipeline is provided with ratchet, the spine on the swivel joint of cylinder body on the jaw
It is provided with pawl on floating pawl and floating pawl stage clip, the ratchet and pawl tension spring is installed, transmission spine is installed in the housing
Wheel and drive shaft assembly, retaining pawl and retaining pawl extension spring, the afterbody of the housing are provided with counter-force arm component, the counter-force arm group
Part is closely connected with the housing by interior external tooth.
As optimization, the swivel joint is 360 ° * 180 ° of swivel joint.
As optimization, the counter-force arm component is around the housing into rotation any angle.
As optimization, the jaw is hinged with the ratchet.
The beneficial effects of the invention are as follows:
The present invention is suitable for oil drilling preventer, and all parts of the present apparatus use the aluminum titanium alloy of high intensity,
Lightweight, profile is small, and the tense-lax for adapting to nut and bolt in small space is buckled, and can by control link closely when hydraulic coupling it is big
The small size come the torque that controls to link closely.

Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the present invention is described in detail.
Shown in reference picture 1, Fig. 2, a kind of hollow type hydraulic pressure spinner, including housing 7 is provided with oil cylinder in the housing 7
Body, piston rod 8 and jaw 6, the piston rod 8, which is provided with cylinder body in piston 9, the cylinder body, is provided with pipeline, the pipeline
One end connection piston two ends oil inlet and outlet, the other end connection of the pipeline is on the swivel joint 10 of cylinder body, institute
State and ratchet 5 is installed on jaw 6, be provided with floating pawl 3 and floating pawl stage clip 2, the ratchet 5 and be provided with the ratchet 5
Drive ratchet and drive shaft assembly 1, retaining pawl 11 and retaining pawl extension spring 12 are installed in pawl tension spring 4, the housing 7, it is described
The afterbody of housing 7 is provided with counter-force arm component 13, and the counter-force arm component 13 is closely connected with the housing 7 by interior external tooth.
The swivel joint 10 is 360 ° * 180 ° of swivel joint.
The counter-force arm component 13 rotates any angle, the placement of counter-force arm when facilitating spinner around the housing 7.
When high pressure liquid force feed enters 7 afterbody cylinder body rear interior cavity of housing from 360 ° × 180 ° swivel joints 10, piston 9 is pushed away
Piston bar 8 is moved forward, and piston rod 8 drives jaw 6 and the ratchet 5 being hinged with jaw 6 to move forward, and ratchet 5, which is promoted, to be passed
Dynamic ratchet and drive shaft assembly 1 are rotated, and the inside of Drive ratchet and drive shaft assembly 1 is interior six sides, can entangle hex nut
Both sides are linked closely or released respectively operation, and in movement forward, under the pulling force effect of pawl tension spring 4, ratchet 5 is with spine
Wheel 1 can be in close contact all the time, it is ensured that the stability of transmission；When hydraulic oil enters cylinder body front interior cavity, piston 9 drives piston rod
8th, jaw 6 and the ratchet 5 being hinged with jaw 6 are moved rearwards by, in moving process, and the effect of floating pawl stage clip 2 can guarantee that floating
Pawl 3 is in close contact with ratchet, and the effect of retaining pawl extension spring 12 can guarantee that retaining pawl is in close contact with ratchet 1, so both ensure
Ratchet 5 moves smooth backward, also prevent ratchet 1 and retreats.Due to nut can apply to spinner during shackle on nut bolt
Countertorque, so counter-force arm component 13 is to be eliminated countertorque, and counter-force arm component 13 in spinner equipment for leaning against
It can be facilitated with any rotation and leaned against by spinner equipment appropriate location.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
