Road;When lower oil tube, when its oil pipe (or other tubing string) is by its main latus rectum structure, its roller assembly
Being positioned on the certain position of housing hollow structure, its roller assembly specification can set as required, i.e. works as liquid
Force feed respectively enters in two cylinder tubes, is inwardly advanced by piston 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.
