Description

Tunnel vault settlement measurement Special hanging chi

Technical field

The utility model relates to a kind of Special hanging chi of settlement measurement, especially a kind of Special hanging chi of tunnel vault settlement measurement.

Background technology

At present, the extension ruler measurement mode generally adopted in tunnel vault settlement measurement has two kinds.One is connect " S " type hook at fish pole peak, ordinary steel tape measure is hung on the hook of " S " type hook bottom, by telescopic rod, the hook on " S " type hook top is directly suspended from vault hook again, then by extended steel tape measure to correct position, after steel tape geo-stationary, spirit-leveling instrument is coordinated to carry out level measurement; Two is be welded with metal hanger at common Sopwith staff top, Sopwith staff is stretched to appropriate length rear overhang and is hung on vault hook, after Sopwith staff geo-stationary, coordinate spirit-leveling instrument to carry out level measurement.

But the former hangs in ruler measurement process, and fishing rod deflection deformation is larger, suspension is difficult to control, due to ordinary steel tape measure light matter and thin body, by airflow influence unstable in tunnel, be difficult to reach so-called relative static conditions, often there is waving or offseting to a certain degree in steel tape, cause measurement error comparatively large, and the common Sopwith staff xsect that the latter adopts is cuboid design, holding chi, to hang feel not good, in addition conduct oneself with dignity comparatively large, cause suspension difficulty larger.

The more distinct issues that both exist are exactly by the non-rotatable restriction of self structure, after once hanging, blade cannot freely rotate, be difficult to ensure to hang rear chi face just to spirit-leveling instrument, force in reading process to have to repeatedly adjust and hang direction or need erection spirit-leveling instrument of repeatedly shifting one's position.Except, two kinds of metering systems affect reading difficulty by the low light level residing for tunnel, need by bright light torch.

Utility model content

The purpose of this utility model is to provide a kind of Special hanging chi measuring tunnel vault sedimentation.

The technical solution of the utility model is, a kind of tunnel vault settlement measurement Special hanging chi, and arranging in junction, chi masthead portion can 360 ° of globe joint horizontally rotated, and the spin in globe joint is connected with hook, is carved with scale in the positive and negative two survey faces of chi bar.

Described chi bar is telescopic sleeving rod, is socketed and forms, long 0.8 ~ 1.6 meter of single-unit loop bar by 5 ~ 8 joint loop bars.

The medial surface often saving loop bar has chute, lateral surface has draw runner, chute matches with draw runner.

Be 1mm in the scale unit of chi bar front scale, the scale unit of reverse side scale is 5mm.

Fluoresent coating is scribbled on chi bar surface.

Lubricating oil is coated with in globe joint.

The utility model has following technique effect, and 1, the chi bar laminating degree of chi face and palm in chi suspension process that is in one's hands is high, uniform force, hangs in chi process and is easy to control; 2, upper hook and chi bar top end use and can be connected by 360 ° of globe joints horizontally rotated, after extension chi has hung, adjustment blade can be rotated freely with spirit-leveling instrument decorating position 360 ° of levels, make it just to spirit-leveling instrument, after blade geo-stationary, just can accurate reading.3, chi bar is socketed by 5 ~ 8 joint loop bars and forms, long 0.8 ~ 1.6 meter of single-unit chi bar, and adjacent two joint chi bar telescopic connection bilaterals are fixed by movable buckle, and resistance to overturning is good, less by air-flow flow effect.4, be 1mm in chi bar front scale scale unit, reverse side scale scale unit, for being 5mm, scribbles fluoresent coating on chi bar surface, conveniently reading 5, globe joint are coated with lubricating oil under low light environment, globe joint can 360 ° horizontally rotate, hang direction repetitive measurement without the need to adjustment.6, structure is simple, is easy to operation, uses flexibly, adapts to the Special complex environment residing for tunnel vault settlement measurement.
