Description
Technical field
The present invention relates to a kind of measurement apparatus of spiral lift pressure vessel height, it is more particularly to a kind of using magnetostriction principle come the device of the amount of inspection spiral lift pressure vessel height.
Background technology
Spiral lift pressure vessel is constantly above grown as the rise of pressure can form -45 degree of spiral changes of -45 degree, is measured using pressure guiding pipe.When left rotation and right rotation occurs in spiral lift pressure vessel uphill process, pressure guiding pipe winding can be caused, knotted, fracture, can not used time truly detection container height, often operative employee is to check, speculate by rule of thumb, without corresponding scientific basis, can not also understand and detect the small movement locus state of gas holder, the firsthand information can not be obtained in time carries out reasonable adjusting, the actual height of container is not known about to operative employee, blindly operation regulation, easy generation container take out negative security incident.
The content of the invention
A kind of height rangefinder device of spiral lift pressure vessel of this offer, it is safer come the amount of inspection spiral lift pressure vessel height, its big panel height of precision measured using magnetostriction principle.
The object of the present invention is achieved like this：A kind of height rangefinder device of spiral lift pressure vessel includes being located at spiral lift pressure vessel top supporting rod, and support bar is provided with rotating shaft, and locating rod one end connection rotating shaft, the other end are provided with magnetic sheet；
Magnetostriction feeler lever is located at spiral lift pressure vessel side, parallel with spiral lift pressure vessel, and magnetostriction feeler lever is provided with magnetic sheet groove, and magnetic sheet is caught in magnetic sheet groove and slided along magnetic sheet groove；
Feeler lever gauge outfit is connected on magnetostriction feeler lever.
Further, magnetic sheet is provided with fixing hole, and locating rod connection magnetic sheet end is provided with gland, gland insertion fixing hole.
Further, locating rod is provided with middle studdle, and middle studdle lower end is provided with universal wheel, and universal wheel is in contact with spiral lift pressure vessel top.
It is also possible that connected between middle studdle and locating rod by spring.
The present invention has advantages below：
1st, the precision of measurement is high, and external disturbance is few, can be suitably used for the adverse circumstances such as dense fog, rainy day.
2nd, the efficiency of measurement can with the height of the real time measure spiral lift pressure vessel, be improved.
3rd, without survey crew to in-site measurement, the security of measurement is improved.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is preferable magnetic sheet and locating rod connection diagram.
In figure：Spiral lift pressure vessel 1, support bar 2, rotating shaft 3, locating rod 4, magnetic sheet 5, magnetostriction feeler lever 6, magnetic sheet groove 7, feeler lever gauge outfit 8, middle studdle 9, universal wheel 10, fixing hole 11, gland 12.
Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings：
Such as Fig. 1, a kind of height rangefinder device of spiral lift pressure vessel includes being located at the top supporting rod 2 of spiral lift pressure vessel 1, and support bar 2 is provided with rotating shaft 3, and one end connection rotating shaft 3 of locating rod 4, the other end are provided with magnetic sheet 5；
Magnetostriction feeler lever 6 is located at the side of spiral lift pressure vessel 1, parallel with spiral lift pressure vessel 1, and magnetostriction feeler lever 6 is provided with magnetic sheet groove 7, and magnetic sheet 5 is caught in magnetic sheet groove 7 and slided along magnetic sheet groove 7；
Feeler lever gauge outfit 8 is connected on magnetostriction feeler lever 6, feeler lever gauge outfit 8 receives the strain-pulse signal that magnetostriction feeler lever magnetic field is crossed to form with magnetic sheet magnetic field, because the distance between this transmission time and magnetic sheet and feeler lever gauge outfit 8 of strain wave pulse signal in magnetostriction feeler lever 6 is directly proportional, pass through time of measuring, it is possible to highly precisely determine magnetic sheet and the distance of feeler lever gauge outfit 8；
Measuring principle：When spiral lift pressure vessel 1 is moved up and down or rotated, crown center is because installed rotating shaft 3, locating rod 4 will not rotate simultaneously with spiral lift pressure vessel, a position can be maintained at, drive locating rod 4 if spiral lift pressure vessel 1 moves up and down while move up and down, magnetic sheet 5 and the contact point of magnetostriction feeler lever 6 are also with moving up and down in locating rod 4, signal is reached feeler lever gauge outfit 8 and is converted to 4-20mA signals by magnetostriction feeler lever 6 is input to secondary meter, can promptly and accurately show the actual height of spiral lift pressure vessel 1.Its measurement result is reliable, and external disturbance is few, can be suitably used for the adverse circumstances such as dense fog, rainy day.Solve that existing spiral lift pressure vessel containment measurement apparatus measurement accuracy is poor, and labor strength is big, it is impossible under adverse weather condition the problem of stable operation
Preferably, locating rod 4 is provided with middle studdle 9, and the lower end of middle studdle 9 is provided with universal wheel 10, and universal wheel 20 is in contact with the top of spiral lift pressure vessel 1.Setting middle studdle 9 can be crossed to 4 one support forces of locating rod, make locating rod 4 will not be because of length more than three meters, measurement accuracy is lost directly caused by self-deformation is excessive when moving up and down.
It is further preferred that connected between middle studdle 9 and locating rod 4 by spring.
In Fig. 2, it is preferred that magnetic sheet 5 is provided with fixing hole 11, and locating rod 4 connects the end of magnetic sheet 5 and is provided with gland 12, and gland 12 inserts fixing hole 11.In measurement, when locating rod 4 is influenceed to occur small deflection by spiral lift pressure vessel（Its spiral lift pressure vessel height does not change, is only limited by the variation of volume, locating rod 4 is produced certain moving）, gland 12 relatively rotates with fixing hole 11, to weaken influence of this situation to measurement accuracy.
