Description
Technical field
The present invention relates to mechanical field, specifically a kind of blowout preventer manual locking bar revolution meter.
Background technology
At present, blowout preventer manual locking bar revolution meter is divided into mechanical transmission-type counter, contact friction formula revolution meter and cotton rope formula counter.Principle is when main body rotates, and is counted by the rotating cycle of counter block to check lock lever of the indirect actuation counter of mode such as gear, chain, belt, flexible axle.Existing counter resist low temperature, anti-freeze ability is weak, fragile under the service condition of high frequency, high energy vibrations, anti-external force, waterproof antifouling property are poor, ageing-resistant limited with antiseptic power, make the failure rate of counting assembly and spoilage very high, even cannot use under some conditions, thus lack the effective monitoring to manual check lock lever, bring great potential safety hazard to well control safety.
Summary of the invention
The deficiency of weak, fragile under high-frequency vibration, the ageing-resistant ability of low temperature ability is resisted in order to overcome existing blowout preventer manual locking bar revolution meter, the invention provides a kind of blowout preventer manual locking bar revolution meter, this blowout preventer manual locking bar revolution meter counting accurately, structure simple rigid, anti-soil, waterproof, ageing resistance are strong, in sharp freezing, under the extreme conditions such as high frequency, high energy vibrations, permanently effective use can be met.
Technical scheme of the present invention is: a kind of blowout preventer manual locking bar revolution meter, comprise tubular body, the spiral barrier that described tubular body outer setting has pitch identical, and the external stability of spiral barrier has translucent cover, the airtight spiral space that translucent cover and spiral barrier are formed is built-in with spheroid pointer, tubular body is connected with scale by the rotating scale ring in its two ends, and scale is parallel with tubular body axis direction, is fixed with angle scale between tubular body outside and the scale ring of one end.
Described scale is marked with scale, and scale is corresponding with spiral barrier spacing.
Described tubular body two ends are fixed with left side wall and right side wall respectively, and the outer of left side wall and right side wall and translucent cover are tightly connected, and described angle scale is fixed on the left of left side wall, and the scale ring on the left of angle scale is provided with pointer.
Described right side wall has lubrication hole.
Described tubular body is fixed on manual locking bar by the jackscrew at two ends.
The present invention has following beneficial effect: owing to taking such scheme, the airtight spiral space that spiral barrier and translucent cover are formed is built-in with spheroid pointer, tubular body carries out synchronous axial rotation along with the rotation of manual locking bar, the bottom transverse of spheroid pointer in airtight spiral space moves, scales different on the corresponding scale of spheroid pointer, thus demonstrating the number of turns, the angle less than a circle is then presented on angle scale by pointer on scale ring.This counter adopts number of turns counting and angle to count two kinds of counting mode combinations, counting precisely, blowout preventer manual locking bar can be met completely at horizontality and the rotating cycle under certain pitch angle and deflection angle state and angular measure, the running of spheroid pointer and rotary scale adopts gravity control, avoid artificial the interference and maloperation, effective monitoring is implemented to the aperture of check lock lever.This counter is full mechanism structure simultaneously, simple structure, firm, can resist outside destroy under normal circumstances, possess extremely strong waterproof and stain resistance, in sharp freezing, can meet permanently effective use under the extreme conditions such as high frequency, high energy vibrations.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
By shown in Fig. 1 to Fig. 3, a kind of blowout preventer manual locking bar revolution meter, comprises tubular body 11, and described tubular body 11 is fixed on manual locking bar 16 by the jackscrew 1 at two ends.The spiral barrier 6 that described tubular body 11 external process has pitch identical, the tubular body 11 of spiral barrier 6 both sides is fixed with respectively left side wall 13 and right side wall 14, and align with spiral barrier 6 outer in the outer of left side wall 13 and right side wall 14, above-mentioned left and right sidewall 14 has translucent cover 5 with spiral barrier 6 external stability, and the airtight spiral space 15 that translucent cover 5 and spiral barrier 6 are formed is built-in with spheroid pointer 12.The two ends of airtight spiral space 15 are fixed with the resistance sheet 8 perpendicular to tubular body 11, for the zeroing of spheroid pointer 12 and spacing, in simultaneously prevent spheroid pointer 12 to be stuck in narrow and small angle that spiral barrier 6 end and left and right sidewall formed.
Be fixed with circular angle scale 4 on the left of the left side wall 13 of tubular body 11, and angle scale 4 is marked with angle.Tubular body 11 on the left of angle scale 4 is externally connected to rotating scale ring 2, and this scale ring 2 is provided with pointer.Be provided with annular gasket 3 between scale ring 2 and angle scale 4, touch mutually with angle scale 4 to prevent scale ring 2.Also be fixed with scale ring 2 on the right side of the right side wall 14 of tubular body 11, and be also fixed with annular gasket 3 between the scale ring 2 on right side wall 14 and right side.Two the scale rings 2 in left and right are connected with scale 9 respectively by scale support arm 7, and described scale 9 is parallel with tubular body 11 axis direction, and scale 9 is marked with scale, and scale is corresponding with spiral barrier 6 spacing.Meanwhile, because scale ring 2 can rotate around tubular body 11, make scale 9 under the weight effect of himself weight and scale support arm 7, direction all the time straight down.Described right side wall 14 has lubrication hole 10, to annotate in airtight spiral space 15 anti-freezing damping fluid by lubrication hole 10.
Operationally, first manual locking bar 16 is unlocked and put in place, then this counter cover is contained on manual locking bar 16, and leave enough extendable rooms with check lock lever support 17.Revolution meter body, makes zero spheroid pointer 12, and makes scale 9 be on gravity vertical plane, and the number of degrees of the pointer on scale ring 2 on angle scale 4 are zero, and the jackscrew 1 that is tightened is by device fixation.When manual locking bar 16 rotates hour counter with its synchronous axial system, the horizontal thrust that spheroid pointer 12 is subject to gravity and spiral barrier 16 acts on transverse shifting in airtight spiral space 15, and scale 9 keeps vertically downward under gravity.After manual locking bar 16 has rotated, observe spheroid pointer 12 present position can read rotating cycle by scale 9, the indicated numerical value on angle scale 4 of the pointer on scale ring 2 is the deflection angle of not enough whole circle.
During this blowout preventer manual locking bar revolution meter is tested at the scene, device drops body without any damage from 5 meters of height freely falling bodies, and antidetonation, anti-damage ability are outstanding; Fast, 1 people can complete in 5 minutes for installation, convenient disassembly; It is good that underwater sealing tests its sealing effectiveness; In resistance to defile test, after device is covered with mud, just can reading smoothly through simple wiping; Device serviceability temperature scope is-40 ° ~ 80 °.Direct-reading precision is 15 °, and valuation is 7.5 °, and reading accuracy meets designing requirement, and completely avoid the various deficiencies of existing apparatus, effect is remarkable.
