Abstract
The invention discloses a turn-lock torque measuring and digitally displaying device for large power tongs. The device comprises a lower casing and an upper casing, the lower casing is provided with a turn-lock binding clip and the upper casing, the upper casing is provided with a hydraulic motor, a ramp groove of the lower casing is internally provided with a cylindrical wedge-surface ramp, the turn-lock of binding clip includes two pairs of turn-lock parts, each pair of turn-lock part comprises a jaw plate, a dovetail groove of the jaw plate is provided with a toothed plate, and a pin and a roller are mounted in a hole of the jaw plate; and a valve plate of the hydraulic motor is provided with a torque digitally displaying instrument, a door frame is mounted at the two arm ends of an opening of the lower casing, one end of a couple sensor is fit with one arm end of the opening of the lower casing, the other end of the couple sensor is fixedly connected with one end of the door frame, and the other end of the door frame is movably connected with the other arm end of the opening of the lower casing via a pin. The mounting and dismounting turn-lock torque is directly measured via the turn-lock binding clip of the large power tongs, the method is reliable, the structure is reasonable, and the measured turn-lock torque is real and believable.
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 Hubei Province plate roller " climbing " to drive dental lamina " to bite " the tubular pillar drilling tools such as drilling rod, sleeve pipe, oil pipe to carry out upper shackle operation, its carrying moment is very large, very direct on the workload impact of drilling operation, so the moment of torsion measuring and control power tongs is extremely important.The method of the torque measurement of existing various power tongs is unreasonable, numerical value is not too true and reliable, such as Chinese patent ZL90102517, ZL97116001.5 etc. are the torque values of the upper shackle of oil pressure tabular value conversion of using the power source oil motor measuring power tongs, the signal that ZL20061098182.6 then adopts the binding clip moment of torsion of power tongs to produce on planetary transmission body through the reaction torque that stage-geared produces converts tong moment of torsion to by sensor, has many errors with the actual torque of binding clip.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, measure on power tongs and unload the true and reliable spinner power tongs torque measurement digital display device of spinner torque.
Technical solution of the present invention is:
A kind of spinner power tongs torque measurement digital display device, comprise lower house, upper shell, it is characterized in that: lower house fills spinner binding clip and upper shell, upper shell fills oil motor, fill cylinder wedge surface ramp in the ramp groove of lower house, spinner binding clip has two pairs of spinner parts; Often pair of spinner parts comprise jaw, fill dental lamina in jaw dovetail groove, fill pin and roller in the plate hole of Hubei Province; The valve plate of oil motor fills digital display torque meter, the two-arm end dress doorframe of lower house opening, one end of couple sensor and an arm end of lower house opening are fitted, the other end of couple sensor is fixedly connected with one end of doorframe, and the other end of doorframe is flexibly connected with another arm end bearing pin of lower house opening; Oil motor drives the pin of the spinner parts of spinner binding clip and roller to rotate on cylinder wedge surface ramp through stage-geared, drive the dental lamina on the plate of Hubei Province to sting tight tubular pillar drilling tool generation torque and carry out upper shackle operation.
Spinner torque produces to lower house and doorframe the vector couple F be added
12, the spinner binding clip center of circle is to the vertical radius vector y of doorframe center line, spinner torque T=YF
12, the signal wire transmission that the vector couple value that doorframe produces is occurred by couple sensor, to digital display torque meter, converts torque value numerical monitor to.
The present invention directly measures from power tongs spinner binding clip and unloads spinner torque, and method is reliable, and rational in infrastructure, spinner torque is genuine and believable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is spinner tong structural representation of the present invention.
Fig. 2 is spinner power tongs binding clip of the present invention and torque measurement digital display device structural representation.
