The mechanical arm used for fixing the oil drip rod has the advantages of simple structure, being used conveniently, high stability, capability of reducing errors effectively and so on. The mechanical arm structurally comprises a bottom parallel plate, a support arranged on the bottom parallel plate, and a cylindrical fixer arranged on the top of the support; the oil drip rod is arranged inside the cylindrical fixer.
Description
Technical field
The utility model relates to a kind of special-purpose aid of metering outfit ullage rule, relates in particular to a kind of ullage rule and fixedly uses mechanical arm.
Background technology
Ullage rule is a metering outfit of accurately measuring interior oil of big-and-middle-sized container and liquid petroleum product liquid level in the petroleum and petrochemical industry.At petroleum and petrochemical industry, often utilize big-and-middle-sized containers store or transportation oil and liquid petroleum products such as oil tank, oil carrier, tank car, truck tank.In the important step of handing-over, transmission, need be with liquid level position in the accurate measuring vessel of ullage rule, and in " vessel volume table " the verification liquid volume numerical value corresponding with this liquid level.
Accurately the common technology of the interior liquid level of measuring vessel is that manual method is measured at present, promptly according to the regulation of " GB/T13894-1992 oil and liquid petroleum product level gauge (manual method) ", the testing staff is positioned at the dipping hole place (the selection tank deck ventilating opening of no dipping hole) of big tank top, utilizes professional metering outfit-ullage rule to finish.Standard-required: dipping personnel one hold the ullage rule handle, and rotation crank is transferred chi stone roller and chi band on the other hand, make chi stone roller and part chi band steadily enter liquid level, keep this state a period of time and read the corresponding chi band of dipping hole scale h
1Carry chi stone roller and chi band then on the rotation crank, read the scale h of pasta vestige edge
2Liquid level true altitude H can draw according to following computing formula.
H=H
Dipping hole-(h
1-h
2)
In the formula:
H
Dipping hole-dipping hole can be looked into big jar of raw data or on-the-spot the survey with reference to height;
h
1The chi band scale of dipping hole correspondence during-in-site measurement:
h
2-pasta vestige edge scale:
Present technical operation drawback is the hand-held chi of testing person one rotation crank on the other hand, and stationarity that can not the guaranteed discharge dipstick is easier to produce error in measuring process.For one 10000 cubic metres oil storage vertical tank, liquid level gauging data error 1mm, corresponding liquid volume data error is exactly 7m
3
Summary of the invention
The purpose of this utility model is exactly that stationarity is not good in use in order to solve present ullage rule, is easy to generate problems such as error, provides a kind of and has simple in structurely, easy to use, and stationarity is good, can effectively reduce the ullage rule of advantages such as error and fixedly use mechanical arm.
For achieving the above object, the utility model adopts following technical scheme:
A kind of ullage rule is fixing uses mechanical arm, and it comprises bottom parallel plate, mounting bracket on the bottom parallel plate, and top, support top is the tubular fixator, ullage rule is installed in the tubular fixator.
Described support is a upper angled.
Described bottom parallel plate is made of a pair of concave arc triangle edge plate that cooperates up and down, and they run through connection by support, and wherein Shang Fang bottom parallel plate is provided with a pair of set bolt.
Two pairs of staggered vertically arranged nuts of described tubular fixator outside welding are equipped with the bolt to inward turning in each nut, two pairs of bolts are fixed on tubular fixator inner space with the ullage rule handle.
The utility model purpose is to be used with ullage rule, ullage rule is fixed on the horizontal outer edge of big jar of dipping hole (or ventilating opening), avoids holding by hand the chi operation and jitter phenomenon occurs, improves the accuracy and the repeatability of test data, and saves manpower.This product is applicable to that tank deck dipping hole (or ventilating opening) has the metering scene of horizontal outer.Its mechanical arm integral body is the C type, is made of bottom parallel plate, support and top tubular fixator, the whole stainless steel that adopts.The bottom is the double-deck parallel-plate of concave arc triangle edge, has two set bolts on the parallel-plate of upper strata, is used for mechanical arm is blocked and is fixed on the laterally projecting outer of big jar of dipping hole.The high 250mm of mechanical arm support raises the operating space, is convenient to the operation of survey crew.Two pairs of staggered vertically arranged nuts of the tubular fixator outside welding on arm top are equipped with the bolt to inward turning in it.The tubular fixator can insert the ullage rule handle of multiple model, blocks the ullage rule handle by inside swivel bolt and is fixed.Be fixed on duty such as Fig. 4 on jar mouthful outer.
The utility model beneficial effect is: easy to operate, volume is small and exquisite to be easy to carry, and practicality is better.

Wherein, 1. bottom parallel plate, 2. support, 3. tubular fixator, 4. set bolt, 5. nut, 6. bolt, 7. ullage rule.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Among Fig. 1, mounting bracket 2 on the bottom parallel plate 1, and top, support 2 top is a tubular fixator 3, and ullage rule 7 is installed in the tubular fixator 3.Support 1 is a upper angled.Bottom parallel plate 1 is made of a pair of concave arc triangle edge plate that cooperates up and down, and shown in Fig. 2, Fig. 2 a, they run through connection by support 2, and wherein Shang Fang bottom parallel plate 1 is provided with a pair of set bolt 4.Two pairs of staggered vertically arranged nuts 5 of tubular fixator 3 outsides welding, shown in Fig. 3, Fig. 3 a, 6, the two pairs of bolts 6 of bolt that are equipped with in each nut 5 to inward turning are fixed on tubular fixator 3 inner spaces with ullage rule 7 handles.
During use, at first, tighten two set bolts, the 4 solid mechanical arms on bottom parallel plate upper strata with a double-deck parallel-plate 1 in mechanical arm bottom and a jar mouthful horizontal extension level chucking; Then the ullage rule handle is inserted mechanical arm upper end tubular fixator 3, and tighten four the bolt 6 fixed amount dipstick handles in the outside, ullage rule is fixed on jar mouthful outer.Testing staff's rotation crank is finished down the chi test job, guarantees that the locus of ullage rule in the test overall process is not moved, and improves test data accuracy and repeatability.
