Description
Technical field
The present invention relates to a kind of spinner power tongs torque measurement digital display device.
Background technology
Petroleum drilling and mining Power Tong adopts Jaw plate roller " climbing " to drive dental lamina " to bite " tubular pillars such as drilling rod, sleeve pipe, oil pipe
Carrying out upper shackle operation, it carries, and moment is very big for drilling tool, and the workload impact on drilling operation is very direct, so measuring and slapping
The moment of torsion of control power tongs is extremely important.The method of the torque measurement of existing various power tongs is unreasonable, and numerical value is less true
Reliable, such as Chinese patent zl90102517, zl97116001.5 etc. is the power source hydraulic pressure horse borrowing measurement power tongs
The torque value of the upper shackle of oil pressure tabular value conversion reaching, zl20061098182.6 then adopts the binding clip moment of torsion of power tongs through multistage
The signal that the reaction torque that gear drive produces produces on planetary transmission body is converted into tong by sensor and turns round
Square, has many errors with the actual torque of binding clip.
Content of the invention
It is an object of the invention to provide a kind of rational in infrastructure, on measurement power tongs on to unload spinner torque true and reliable
Spinner power tongs torque measurement digital display device.
The technical solution of the present invention is:
A kind of spinner power tongs torque measurement digital display device, including lower house, upper shell, is characterized in that: on lower house
Dress spinner binding clip and upper shell, upper shell fills hydraulic motor, fills cylinder wedge surface ramp, spinner binding clip in the ramp groove of lower house
There are two pairs of spinner parts；Each pair spinner part includes jaw, fills dental lamina in jaw dovetail groove, dress pin and roller in Jaw plate hole；
Digital display torque meter, two-arm end dress doorframe, one end of couple sensor and the lower casing of lower house opening are filled on the valve plate of hydraulic motor
One arm end laminating of body opening, the other end of couple sensor is fixedly connected with one end of doorframe, the other end of doorframe and lower casing
Another arm end bearing pin of body opening is flexibly connected；Hydraulic motor drives the spinner part of spinner binding clip through stage-geared
Pin and roller rotate on cylinder wedge surface ramp, drive the dental lamina in Jaw plate sting tight tubular pillar drilling tool produce torque carry out on unload
Button operation.
Spinner torque produces, to lower house and doorframe, vector couple f being added12, the spinner binding clip center of circle to doorframe center line hang down
Straight radius vector y, spinner torque t=yf12, the signal wire transmission that on doorframe, the vector couple value of generation is occurred by couple sensor
To digital display torque meter, it is converted into torque value numerical monitor.
The present invention directly unloads spinner torque from the measurement of power tongs spinner binding clip, and method is reliable, and rational in infrastructure, spinner turns
Square is genuine and believable.
Brief description
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the spinner tong structural representation of the present invention.
Fig. 2 is spinner power tongs binding clip and the torque measurement digital display device structural representation of the present invention.
Specific embodiment
A kind of spinner power tongs torque measurement digital display device, including lower house 2, upper shell 3, lower house fills turnbuckle clamp
1 and upper shell, upper shell fills hydraulic motor 5, in the ramp groove of lower house, fills cylinder wedge surface ramp, spinner binding clip 1 has two
To spinner part；Each pair spinner part includes jaw 8, fills dental lamina in jaw dovetail groove, dress pin 9 and roller 10 in Jaw plate hole；
On the valve plate of hydraulic motor fill digital display torque meter 4, lower house opening two-arm end dress doorframe 7, one end of couple sensor 11 with
One arm end laminating of lower house opening, the other end of couple sensor is fixedly connected with one end of doorframe, the other end of doorframe and
Another arm end bearing pin 6 of lower house opening is flexibly connected；Hydraulic motor drives the spinner of spinner binding clip through stage-geared
The pin of part and roller rotate on cylinder wedge surface ramp 12, drive the dental lamina in Jaw plate to sting tight tubular pillar drilling tool and produce torque
Carry out upper shackle operation.
Spinner torque produces, to lower house and doorframe, vector couple f being added12, the spinner binding clip center of circle to doorframe center line hang down
Straight radius vector y, spinner torque t=yf12, the signal wire transmission that on doorframe, the vector couple value of generation is occurred by couple sensor
To digital display torque meter, it is converted into torque value numerical monitor.
