Abstract
The invention relates to a buffer device of a nominal diameter gauge for detecting the whole-length nominal diameter of an oil casing pipe. The buffer device comprises an installation support, wherein a spring base is fixed on one side of the installation support; a central spindle is arranged in the spring base in a sliding matching manner; a cavity in which the central spindle slides is arranged inside the installation support; the outer end of the central spindle stretches out of the spring base, and a baffle pressing cap is fixed at the outer end part of the central spindle; and a spring is arranged between the baffle pressing cap and the spring base and is sleeved on the central spindle. As the spring is arranged between the baffle pressing cap and the spring base and is used for absorbing the impact force of the nominal diameter gauge, the nominal diameter gauge is prevented from being damaged because of overlarge stress, and the detection cost is saved; and because of the buffer function of the spring, noises generated when the nominal diameter gauge bumps a baffle can be reduced.
Description
Technical field
The present invention relates to the pick-up unit of petroleum pipe line, specifically a kind of snubber assembly that is used to detect the drift diameter gauge of tubing and casing total length latus rectum.
Background technology
In order to guarantee that the tubing and casing internal diameter adheres to specification, must adopt drift diameter gauge that the tubing and casing total length latus rectum of making is detected.Common detection method is: drift diameter gauge utilizes gaseous tension to do power and pushes from an end of pipe to be detected, ejects from the other end.In order to stop drift diameter gauge, be provided with iron plate at the end certain intervals place that ejects of distance pipe to be detected.When the air pressure that drift diameter gauge is received was excessive, the noise that the strength of impact is damaged drift diameter gauge and bump easily was very big, and sometimes the drift diameter gauge bump was splashed out, put upside down on the ground, not only influenced production efficiency and existed the accident potential of hurting sb.'s feelings.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of snubber assembly of drift diameter gauge is provided, this device can be protected the drift diameter gauge that from pipe to be detected, ejects.
According to technical scheme of the present invention: a kind of snubber assembly of drift diameter gauge; Comprise erection support, a side of said erection support is fixed with spring pedestal, is sliding combined with mandrel in the said spring pedestal; Be provided with the cavity that supplies said mandrel to slide in the said erection support; The outer end of said mandrel stretches out said spring pedestal and this end end is fixed with the baffle plate pressure cap, is provided with spring between said baffle plate pressure cap and the said spring pedestal, and said spring housing is on said mandrel.
Be fixed with the sleeve that coats said spring pedestal and said spring on the said erection support.
Said sleeve is the subdivision structure.
The side of the fixing said spring pedestal of said erection support is provided with boss.
Said spring pedestal is stretched out in the inner of said mandrel, and on this extension shaft block ring is installed.
Back-up ring is used in the hole that the said mandrel stroke of restriction is installed in the said cavity.
Said baffle plate pressure cap comprises baffle plate and is fixed on the apron block of said baffle plate one side that the outer end of said apron block has threaded hole.
Said baffle plate and said apron block are made of one piece by resin.
Technique effect of the present invention is: the present invention is provided with spring between baffle plate pressure cap and spring pedestal, adopts spring to absorb the impulsive force of drift diameter gauge, can avoid drift diameter gauge stressed excessive and cause scrapping, and practices thrift and detects cost; Owing to the buffer action of spring, also can reduce the noise of drift diameter gauge impingement baffles.

Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of the erection support among the present invention.
Fig. 3 is the structural representation of the baffle plate pressure cap among the present invention.
Embodiment
Be further described below in conjunction with the accompanying drawing specific embodiments of the invention.
Among Fig. 1～Fig. 3, comprise that baffle plate pressure cap 1, spring 2, mandrel 3, spring pedestal 4, trip bolt 5, trip bolt 6, sleeve 7, erection support 8, lock screw 9, shaft block ring 10, hole are with back-up ring 11, boss 12, baffle plate 13, apron block 14, threaded hole 15, cavity 16 etc.
As shown in Figure 1, the present invention is a kind of snubber assembly of drift diameter gauge, comprises erection support 8, spring pedestal 4, mandrel 3, spring 2 and baffle plate pressure cap 1.
The outer end of mandrel 3 stretches out spring pedestal 4 and this end end is fixed with baffle plate pressure cap 1.As shown in Figure 3, baffle plate pressure cap 1 comprises baffle plate 13 and is fixed on the apron block 14 of baffle plate 13 1 sides, and the outer end of apron block 14 has threaded hole 15, mandrel 3 through screw threads for fastening in this threaded hole 15.After baffle plate pressure cap 1 wear damage, can disassemble the baffle plate pressure cap 1 that more renews from mandrel 3.Baffle plate 13 and apron block 14 are made of one piece by resin, and cost is low.
Referring to Fig. 1, between baffle plate pressure cap 1 and spring pedestal 4, be provided with spring 2 again, spring 2 is enclosed within on the mandrel 3, and an end of spring 2 is resisted against on the spring pedestal 4, and its other end is resisted against on the baffle plate pressure cap 1.
On erection support 8, also be fixed with the sleeve 7 that coats spring pedestal 4 and spring 2 through trip bolt 6.Sleeve 7 shields, and can prevent that impurity such as dust from dropping at spring 2 with above the mandrel 3.Sleeve 7 is the subdivision structure, is convenient to dismounting, and two halves is linked into an integrated entity by lock screw 9.As shown in Figure 2, the side of erection support 8 fixing spring bases 4 is provided with boss 12, and sleeve 7 is played positioning action.
As shown in Figure 1, spring pedestal 4 is stretched out in the inner of mandrel 3, and on this extension shaft block ring 10 is installed, and this end of mandrel 3 is played the axial location effect, can prevent mandrel 3 landing from the through hole of spring pedestal 4.The hole that restriction mandrel 3 strokes are installed in the cavity 16 of erection support 8 is with back-up ring 11.
The course of work of the present invention is following: under the effect of drift diameter gauge at air pressure, get to 1 last time of baffle plate pressure cap, spring 2 is compressed, and plays buffer action, can absorb the most impulsive force of drift diameter gauge.When stressed disappearance, drift diameter gauge can drop at assigned address, is sent to given place then, gets into next round again and detects circulation.
The present invention adopts spring 2 to absorb the impulsive force of drift diameter gauges, can protect drift diameter gauge, avoids drift diameter gauge stressed excessive and cause scrapping, and practices thrift and detects cost; Can stop drift diameter gauge by bump splash out the accident potential of hurting sb.'s feelings with avoid damaging other instrument.In addition, owing to the buffer action of spring 2, can reduce the noise of drift diameter gauge impingement baffles.
The present invention is simple in structure, and is easy to maintenance, can effectively improve detection efficiency.
