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 of the drift diameter gauge for detecting tubing and casing total length latus rectum.
Background technology
In order to ensure that tubing and casing internal diameter meets designing requirement, drift diameter gauge must be adopted to detect the tubing and casing total length latus rectum manufactured.Common detection method is: drift diameter gauge utilizes gaseous tension to do power and pushes from one end of detected pipe, ejects from the other end.In order to stop drift diameter gauge, the end certain intervals place that ejects of the detected pipe of distance is provided with iron plate.When the air pressure be subject to drift diameter gauge is excessive, the strength of impact easily damages drift diameter gauge and the noise clashed into is very large, and splash out by drift diameter gauge shock sometimes, puts upside down on the ground, not only affect production efficiency and there is the accident potential of hurting sb.'s feelings.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of snubber assembly of drift diameter gauge, this device can protect the drift diameter gauge ejected from detected pipe.
According to technical scheme of the present invention: a kind of snubber assembly of drift diameter gauge, comprise erection support, the side of described erection support is fixed with spring pedestal, mandrel is sliding combined with in described spring pedestal, the cavity slided for described mandrel is provided with in described erection support, the outer end of described mandrel stretches out described spring pedestal and this end end winding support has baffle plate pressure cap, and be provided with spring between described baffle plate pressure cap and described spring pedestal, described spring housing is on described mandrel.
Described erection support is fixed with the sleeve of coated described spring pedestal and described spring.
Described sleeve is subdivision structure.
The side that described spring pedestal fixed by described erection support is provided with boss.
Described spring pedestal is stretched out in the inner of described mandrel, and this extension is provided with shaft block ring.
The hole back-up ring limiting described mandrel stroke is installed in described cavity.
Described baffle plate pressure cap comprises baffle plate and is fixed on the apron block of described baffle plate side, and the outer end of described apron block has threaded hole.
Described baffle plate and described 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, drift diameter gauge can be avoided stressed excessive and cause scrapping, save testing cost; Due to the buffer action of spring, the noise of drift diameter gauge impingement baffles also can be reduced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of the erection support in the present invention.
Fig. 3 is the structural representation of the baffle plate pressure cap in the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1 ~ Fig. 3, comprise 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 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.
What this snubber assembly was fixed on detected pipe by erection support 8 ejects end.The side of erection support 8 is fixed with spring pedestal 4 by trip bolt 5.Spring pedestal 4 is cylindrical shape, is sliding combined with mandrel 3 in spring pedestal 4, is provided with the cavity 16 slided for mandrel 3 in erection support 8.
The outer end of mandrel 3 stretches out spring pedestal 4 and this end end winding support has 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 side, and the outer end of apron block 14 has threaded hole 15, mandrel 3 by screw threads for fastening in this threaded hole 15.When after baffle plate pressure cap 1 wear damage, can disassemble from mandrel 3, the baffle plate pressure cap 1 more renewed.Baffle plate 13 and apron block 14 are made of one piece by resin, and cost is low.
Again see Fig. 1, be provided with spring 2 between baffle plate pressure cap 1 and spring pedestal 4, spring 2 is enclosed within mandrel 3, and one end of spring 2 is resisted against on spring pedestal 4, and its other end is resisted against on baffle plate pressure cap 1.
Erection support 8 is also fixed with by trip bolt 6 sleeve 7 of coated spring pedestal 4 and spring 2.Sleeve 7 shields, and can prevent the impurity such as dust from dropping on spring 2 with mandrel 3.Sleeve 7 is 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 base 4 is provided with boss 12, positioning action is played to sleeve 7.
As shown in Figure 1, spring pedestal 4 is stretched out in the inner of mandrel 3, and this extension is provided with shaft block ring 10, plays axial location effect to this end of mandrel 3, can prevent mandrel 3 landing from the through hole of spring pedestal 4.The hole back-up ring 11 of restriction mandrel 3 stroke is installed in the cavity 16 of erection support 8.
The course of work of the present invention is as follows: when drift diameter gauge is got on baffle plate pressure cap 1 under the influence of air pressure, spring 2 is compressed, and plays buffer action, the most impulsive force of Absorbable rod drift diameter gauge.When stressed disappearance, drift diameter gauge can drop at assigned address, is then sent to given place, then enters next round detection circulation.
The present invention adopts spring 2 to absorb the impulsive force of drift diameter gauge, can protect drift diameter gauge, avoids drift diameter gauge stressed excessive and cause scrapping, saves testing cost; Drift diameter gauge can be stopped be knocked accident potential that splashing out hurts sb.'s feelings and avoid damaging other instrument.In addition, due to the buffer action of spring 2, the noise of drift diameter gauge impingement baffles can be reduced.
Structure of the present invention is simple, easy to maintenance, effectively can improve detection efficiency.
