Abstract

The utility model provides a double-flexible-rule type liquid sampling winch which is formed by a double-groove winch frame, an operating crank, a double-rule-belt winch, a winch core, rule belts and rule belt buckles. The operating crank and the double-rule-belt winch are installed on a double-groove winch frame through the winch core, the rule belts are installed on the double-rule-belt winch, and rule belt fast-installation buckles are arranged at the tail ends of the rule belts and are connected with the rule belts through rivet buttons. In the whole sampling process, the two rule belts are lifted and fall in parallel mode, do not wind any more, and are not contacted with other objects, so that secondary pollution is avoided. According to the anti-explosion requirements of petroleum products, the operating crank and the winch core are made of a copper alloy, the whole device is of a full metal structure, and the anti-static requirement is met.

Description

A kind of pair of tape measure type liquid sampling capstan winch

Technical field

The utility model relates to the analytical test sampler, specifically a kind of pair of tape measure type liquid sampling capstan winch.

Background technology

In product oil production utilization field, to jet fuel---be commonly called as the requirement that " aviation kerosene " quality has the harshness of being close to, this is because jet fuel directly applies to modern high-speed aircraft (like airliner, fighting opportunity of combat etc.) combustion power system.The heart of high-speed aircraft is a turbojet engine, and fuel feeding is annotated the valve that the plug pump then is undoubtedly this heart, and it annotates the gap of filling in cylinder sleeve is micron order, and any small impurity all can be stuck with it; Aircraft in the high-speed flight is in case notes are filled in pump seizure, and will cause turbojet engine flame-out in flight, direct result is exactly airplane crash.Take a sample for this reason, chemically examined into the indispensable quality monitoring means of aviation kerosene, especially as the oil plant of national strategy deposit, because storage cycle reached more than 10 years, the sampling total degree is considerable especially.This has played crucial effects to guaranteeing the oil plant quality; But new " aviation kerosene " quality index---" suspension " constantly occurs, and caused the new sorrow of people to flight safety in recent years.Although aviation kerosene " suspension " comprise a little what, be still waiting further research; But the author is through finding some base oil depot aviation kerosene generaI investigations; One of seed of trouble of suspension and impurity derives from general at present " sampling rope ", and " electrostatic prevention " rope of this suspension fixed point sampler is though have the advantage that is difficult for producing static; But owing to do not have fixedly turntable and often two-wire use; Interlaced winding behind certain-length, when causing chemical examination, metrological personnel to draw in, the regular oil tank top that is placed on; This not only with on oil plant can stain tank deck, and again dirt is brought into oil tank in the lump, is polluted trapped fuel when taking a sample once more.Perhaps, it is limited that such single pollutes, but then can not be ignored year in and year out, and particularly rope uses back self senile abrasion also will come off for a long time, and this a series of cumulative effect has constituted visible pollutants such as " suspensions " gradually.The user who in real work, has has used metallic bond replacement " electrostatic prevention " rope instead, and " suspension " reduced like this, but staggered winding is also more frequent.

The utility model content

The purpose of the utility model provides a kind of pair of tape measure type liquid sampling capstan winch, not only has operation, easy to carry than traditional " sampling rope ", does not produce static, does not twine, and does not have the wearing and tearing pollutant, does not produce the characteristics of secondary pollution; And tape measure has metering scale, can realize spot sampling more accurately.

The technical scheme of the utility model is: two tape measure type liquid sampling capstan winches are made up of following: the double flute turntable,

Rocking handle, two chi band capstan winches, strand core, chi band, chi bracelet; Rocking handle, two chi band capstan winch are contained on the double flute turntable through the strand core, and the chi band is contained on two chi band capstan winches, and the chi end of tape has chi band fast-assembling to buckle, and chi band fast-assembling is buckled to buckle with the chi band through the fourth of the twelve Earthly Branches and is connected.

Wherein: it is the fixedly skeleton of whole device that the double flute turntable is processed by aluminium alloy.The chi band constitutes after by rubber-like whole piece steel band scale, and two chi band capstan winches split in the double flute turntable groove; Short chi band is the load-bearing band, undertakes the task of hanging whole ST, and long slightly chi band opens and closes band for the ST piston.During work under the effect of ST deadweight two chi bands emit synchronously; According to scale put to the sample position, the long band of little receipts and then open the piston sample introduction; Sample introduction finish unclamp long band, piston is closed; Regain two bands synchronously, accomplish sampling by rocker arms roll.Whole process two chi bands are parallel to be risen and fallen, no longer twines, and does not contact, avoided secondary pollution with its thing.Press the petroleum products requirement of explosion proof, rocking arm, strand core are used copper alloy made, and whole device is an all-metal construction, has satisfied the electrostatic prevention requirement.

Description of drawings

Fig. 1 is two tape measure type liquid sampling capstan winch structural representations of the utility model.

Fig. 2 is two tape measure type liquid sampling capstan winch structural representations (capstan winch rounding state) of the utility model.The synoptic diagram of two tape measure type liquid sampling capstan winch fit on piston samplers of Fig. 3 the utility model.

Among the figure, 1-double flute turntable, 2-rocking handle, 3-two chi band capstan winches, 4-strand core (rocking arm groove), 5-chi band, 6-chi band fast-assembling is buckled, 7-fourth of the twelve Earthly Branches button, 8-jump ring, 9-product oil piston sampler.

Embodiment

Shown in Fig. 1-3, two tape measure type liquid sampling capstan winches of the utility model are by double flute turntable 1, rocking handle 2, two chi band capstan winches 3, strand core 4, chi band 5, chi bracelet 6 formations such as grade; Rocking handle 2, two chi band capstan winch 3 are contained on the double flute turntable 1 through strand core 4, and jump ring 8 axially pins; Two dish chi bands, 5 (one is long and the other is short) are contained on two chi band capstan winches 3, and chi band 6 ends have chi band fast-assembling to buckle 6, and chi band fast-assembling is buckled 6 and buckled 7 through the fourth of the twelve Earthly Branches and be connected with chi band 5.

Only need during use existing piston formula ST drop handle buckled with the chi band fast-assembling of pair tape measure type liquid sampling capstan winches and combine, can take a sample.Short chi band load-bearing when ST puts down, long chi belt sag, piston is closed not sample introduction; After putting into precalculated position (indication of chi band scale), gently pull out the chi band, open the piston sampler piston and begin sample introduction; Unclamp long chi band after a while, piston is closed the completion sample introduction.Draw tape measure in through rocking arm, propose oil sample.

When chi band fast-assembling buckle lifting be the thermometric box time can realize the thermometric of fixing a point, but amount of recovery dipstick function then when changing sounding weight.Be common to various liquid samplings, realize one-object-many-purposes.
