In the petroleum drilling and mining industry of home and abroad, receive the restriction of wellbore space, the downhole tool major part belongs to elongate articles, and connecting thread has two functions usually between the component: one of which provides enough bonding strengths; It two provides sealing reliably.Because downhole tool need be lowered to the underground of several kms, bear high pressure and draw, press, turn round load, so connecting thread each other has application specific standard, different button-types and specification, twisting button moment has demands of different.
Present widely used drilling downhole tool assembling and disassembling stand master clamp device utilizes the piston rod push-and-pull rigidity arm bar of fluid cylinder to produce and twists button (unloading) moment of torsion; The liquid cylinder piston bar stretch out or the process of withdrawing in; Liquid cylinder turns an angle around connecting hinge, causes the arm of force vertical with the liquid cylinder piston bar to take place to change continuously, even fluid cylinder power can be measured accurately like this; Moment also is a value that constantly changes, and is difficult to accurately measure.
The stubborn button moment of common drilling downhole tool connecting thread has an area requirement, although the stubborn button moment error of extrapolating through the length of fluid cylinder pressure and rigidity arm bar is big, also can satisfy the needs of production scene basically.But twist button moment for accurately controlling with brill and the matching requirements of rotary steering downhole tool of precision, the very difficult accurately measurement of existing drilling downhole tool assembling and disassembling stand master clamp device control is twisted and is detained moment.
Summary of the invention
The purpose of the utility model is to provide a kind of drilling downhole tool assembling and disassembling stand novel main clamp device, is difficult to accurately measure the technical problem that button moment is twisted in control to solve traditional drilling downhole tool assembling and disassembling stand master clamp device.
The novel main clamp device of drilling downhole tool assembling and disassembling stand, it comprises following three parts: be master's main pincers part with clamping fluid cylinder assembly and clamping fluid cylinder cylinder frame, caliper bracing frame; Button moment part is twisted in main control; The fixed frame part; The large module gear that button moment part is twisted in said main control passes through spline package on the gear back shaft; Said gear back shaft is packed into and is constituted overall structure in the clamping fluid cylinder cylinder frame; Above-mentioned overall structure reinstalls in two caliper bracing frames, is fixed on then on the lower bottom base in the fixed frame part; The tooth bar piece of large module gear and both sides symmetric arrangement is meshing with each other, and the tooth bar piece is sleeved on the corresponding a pair of guide peg, the tooth bar piece with twist detain fluid cylinder piston rod through being threaded; Twisting button liquid cylinder piston bar and installing that pillar is drawn, pressure sensor between the tooth bar piece is connected additional.
The guide peg lower end is positioned on the guide peg bearing, and the guide peg bearing is fixed on the guide peg support, and the upper end is fixed in the guide peg support, compresses with the locking nut location through last whole junction plate.
When the utility model can satisfy stubborn (unloading) drilling downhole tool connecting thread; Accurately measure and control the requirement of twisting (unloading) moment; When developing accurate downhole tool, assembly equipment accurately is provided reliably, also can be used as a kind of machine for testing torsion simultaneously and use for R&D institution.
