Above, for shackle operation, the working principle of existing hydraulic tongs is as follows:
When upper button operation, upper pincers commutation hand handle 015 and lower pincers commutation hand handle 023 are removed to position on the buckle；
Manipulation transfer cylinder handle 051 is transferred cylinder 03 and is stretched out, hydraulic tongs is pushed integrally to advance to well to progressive position
Mouthful, drilling rod enters in the notch of hydraulic tongs, until the two plug screws up and down in hydraulic tongs are close to tool joint；
Clamping cylinder handle 052 is operated to position on the buckle, clamping cylinder 04 protracts, drive lower pincers 02 to rotate clockwise until
Lower pincers 02 clamp tool joint box；
Hand-operated direction valve 061 is operated to position on the buckle, hydraulic motor 06 rotates forward, and upper pincers 01 rotate clockwise, and clamps drilling rod
Pin end；
High and low shift handle 053 is operated to high tap position, makes to clamp 01 high-speed rotation, until full remaining button in rotation, then operates
To low-grade location, upper pincers 01 link closely to prescribed torque high and low shift handle 053, detain in completion；
Hand-operated direction valve 061 is operated to shackle position, hydraulic motor 06 inverts, and upper pincers 01 rotate counterclockwise, and is retracted to system
In Moving plate 011, and brake disc 011 is driven to rotate；In the case where upper pincers commutation hand handle 015 stops, the notch of upper pincers 01 and brake disc 011
It resets with the notch of lower pincers 02 to just；
Operation clamping cylinder handle 052 is shunk to button bit, clamping cylinder 04 is unloaded, and lower pincers 02 rotate counterclockwise and unclamp drilling rod
Female connector；Lower pincers commutation hand handle 023 stops clamping cylinder 04 to continue to shrink, and lower pincers 02 reset, the notch of lower pincers 02 and upper pincers 01
Notch to just；
For operation transfer cylinder handle 051 to going-back position, hydraulic tongs leaves well head.
When shackle operation, upper pincers commutation hand handle 015 and lower pincers commutation hand handle 023 are removed to shackle position；
Manipulation transfer cylinder handle 051 is transferred cylinder 03 and is stretched out, hydraulic tongs is pushed integrally to advance to well to progressive position
Mouthful, drilling rod enters in the notch of hydraulic tongs, until the two plug screws up and down in hydraulic tongs are close to tool joint；
Clamping cylinder handle 052 is operated to position on the buckle, clamping cylinder 04 is shunk, drive lower pincers 02 to rotate counterclockwise until
Lower pincers 02 clamp tool joint box；
Hand-operated direction valve 061 is operated to shackle position, hydraulic motor 06 inverts, and upper pincers 01 rotate counterclockwise, and clamps drilling rod
Pin end；
High and low shift handle 053 is operated to low-grade location, so that pincers 01 is slowly run, then unscrewing drill operates high and low shift hand
Handle 053 completes shackle until loosening Yu Kouzai is adjusted to low-grade location to high tap position；
Hand-operated direction valve 061 is operated to position on the buckle, hydraulic motor 06 rotates forward, and upper pincers 01 rotate clockwise, and is retracted to system
In Moving plate, and brake disc 011 is driven to rotate；Upper pincers commutation hand handle 015 stop under, it is upper pincers 01 and brake disc 011 notch with
The notch of lower pincers 02 is resetted to just；
The supreme button bit of clamping cylinder handle 052 is operated, clamping cylinder 04 protracts, and lower pincers 02 rotate clockwise and unclamp drilling rod
Female connector；Lower pincers commutation hand handle 023 stops clamping cylinder 04 to continue to protract, and lower pincers 02 reset, the notch of lower pincers 02 and upper pincers 01
Notch to just；
For operation transfer cylinder handle 051 to going-back position, hydraulic tongs leaves well head.
It can be seen that lower pincers commutation hand handle 023 is in the notch reseting procedure of lower pincers 02 during upper shackle operation
It plays an important role.However, existing lower pincers commutation hand handle 023 is usually fixed at lower case close to the one of clamping cylinder 04
Side, and operation panel 05 and clamping cylinder 04 are usually located at the two sides of hydraulic tongs.When actual well drilled operation, operation panel
05 since valve body is more, and operator usually stands in the side of operation panel 05, when needing to operate lower pincers commutation hand handle 023,
Operator need to could operate lower pincers commutation hand handle 023 from operation panel 05 and around one end of hydraulic tongs.
Therefore, when switching upper shackle job state, operator need to continually walk up and down, and operation intensity is big, and there are many latent
Security risk so that the upper shackle operation of hydraulic tongs is extremely inconvenient, convenience is poor.
