Specific embodiment
In order to keep the present invention more obvious and easy to understand, the present invention is done furtherly below in conjunction with the drawings and specific embodiments
It is bright.
As shown in Fig. 1 and Fig. 2 combination, subsea production tree gland step depth cubing of the invention includes gauge head 1, lower copper sheathing
2, sliding needle 3, datum plate 5, upper copper sheathing 6, shaft 7, lever 8, shell 9 and dial gauge 10.
Gauge head 1 is connected to sliding 3 lower part of needle, when gauge head 1 moves upwards, will drive sliding needle 3 and up moves.Sliding 3 lower part of needle set
Equipped with lower copper sheathing 2, sliding 3 top of needle is arranged with upper copper sheathing 6.Datum plate 5 is connect by screw thread with sliding needle 3, which is set in
The outside of sliding 3 certain altitude position of needle, to meet the requirement of certain depth size subsea production tree gland step.Wherein, upper copper
Set 6 and lower copper sheathing 2 are H62 copper product (basis brass that average copper content is 62%), and inner hole adds with sliding 3 outer circle of needle for match grinding
Work forms, therefore during measurement, resistance very little ensure that the precision of measurement.
In the present embodiment, sliding 3 outermost of needle is provided with connector sleeve 4, so that the connection between sliding needle 3 and other component is made
With.
As shown in figure 3, the top of sliding needle 3 is arranged in lever 8, shell 9 is trapped among the outside of sliding needle 3 upper part and lever 8,
Prevent components by environmental damage.
Lever 8 is connect with shaft 7, and 8 side of lever (left end) is directly contacted with the side of the measuring staff of dial gauge 10.When sliding needle
3 up move until shaft 7 starts turning at this time when withstanding the bottom righthand side of lever 8, and drive lever 8 rotates, the upper left of lever 8
The measuring staff of dial gauge 10 is withstood at end, which is moved accordingly along horizontal direction, then pointer rotates on dial, is surveyed
Amount personnel read reading at this time, finally obtain the depth dimensions of subsea production tree gland step.
Wherein, lever 8 is designed using isosceles triangle, so the amount of outputting and inputting is consistent, then survey measurements is not necessarily to
Conversion guarantees measurement accuracy.
In the present embodiment, the multiple of simply subsea production tree gland step depth can be convenient by rotating datum plate 5
Measurement.
As shown in Figure 3 and Figure 4, the present invention provides a kind of measurement method of subsea production tree gland step depth cubing,
Include following procedure:
First cubing is integrally placed in proof-reading block 11, dial gauge 10 is zeroed.It is motionless that reference block 5 is covered with hand, will be examined
Tool is placed on subsea production tree gland step, and reference block 5 is placed on subsea production tree gland step upper surface, prepare into
Row measurement.Wherein, under the action of gauge head 1 and cunning needle 3 are due to gravity, in the case that cubing does not have started measurement, gauge head 1 and cunning
Needle 3 is to fall down.Since sliding 3 lower part of needle is designed using step structure, therefore stop continuing after a distance can only be fallen down
Fall.
When cubing starts measurement, first by the lower plane of the contact subsea production tree gland step of gauge head 1, gauge head 1 is up
Movement (such as since gauge head 1 drops down until after the lower plane of contact subsea production tree gland step, contact surface is to gauge head 1
Reaction drive gauge head 1 to move upwards), so that sliding needle 3 be driven up to move, the upper end of sliding needle 3 can withstand the bottom right of lever 8
End, shaft 7 starts turning at this time, and lever 8 is driven to rotate, and the left upper end of lever 8 withstands dial gauge 10, and survey crew reads at this time
The reading of percentage 10.
Illustratively, when the upper and lower position of moving reference plate 5, the measurement to multiple depth dimensions may be implemented.
It is discussed in detail although the contents of the present invention have passed through above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read above content, for of the invention
A variety of modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
