respectively, makes piston lean on mutually with side door, and they are two years old The centre being spatially located at main latus rectum structure between roller, the space length between its two roller and its oil pipe (or Other tubing string) external diameter identical, two rollers are cut and are against on oil pipe (or other tubing string) body, stablize oil pipe (or other tubing string), makes oil pipe (or other tubing string) be difficult to swing, during oil pipe (or other tubing string) motion, Roller rotates, and roller assembly will not be subjected to displacement, and when the box cupling of oil pipe (or other tubing string) passes through liquid Time in the main latus rectum of depressor, owing to the external diameter of its box cupling is more than the external diameter of oil pipe, when operation, when playing a down tube When column joint (tubing coupling or tool joint) head end begins through hydraulic press center, tubing string highlights body Partly (tubing coupling or tool joint) squeezing roller, makes roller together with roller assembly passively to two by force End is mobile, and the gear shaft that now rack drives on roller assembly is meshed rotates, the gear of hydraulic press The rotating disk that axle connects also will be simultaneously to well head central rotation, and gear shaft end, two ends induction wheel is opposite to each other to well head Central rotation, now by pull bar, is copied to range sensor oil pipe reducing, and range sensor sends electricity Signal, remote control operating platform connects and has display lamp and the warning honeybee accepting distance sensor signal Ring device, now the alarm display lamp on remote control operating platform is glittering, and alarm buzzer is the rapidest Sound, it is thus possible to teaching process personnel's casing adapter part has arrived the center of hydraulic press in time, when connecing Hoop, by rear, when moving to oil pipe body, due to the pressure of hydraulic oil in cylinder tube, pushes away roller assembly To original position, make roller tangent with oil pipe body, thus alarm automatically terminates, due to fluid pressure type box cupling Alarm have employed hydraulic system, and its roller assembly self will not produce vibration, and it stablizes oil pipe, becomes Merit prevents swinging of oil pipe, and when the box cupling of oil pipe is not over roller assembly, roller assembly will not Produce displacement, even if producing high pressure or other complex situations in well, also it will not be produced and affecting, thus liquid Pressure type coupling alarm will not produce false, the situation of wrong report, reports to the police accurately, thus reaches the mesh of the present invention 's.
Owing to have employed technique scheme, fluid pressure type coupling alarm is not only reported to the police accurately, and can also be steady Jet tube.
