Description

Can the level measuring rule pad of connection integrated with scale
Technical field
The invention belongs to field of measuring technique, particularly relate to a kind of convenience different pavement usage, effectively improve measurement of the level precision and efficiency can the level measuring rule pad of connection integrated with scale.
Background technology
Traditional leveling device is made up of spirit-leveling instrument and level scale. First A, Z(that two level scales are placed on ground respectively are called leveling point at 2 during measurement), spirit-leveling instrument is arranged on the mid-way of 2 again, after utilizing leveling, the horizontal sight line of spirit-leveling instrument visual telescope sights the absolute altitude numerical value reading two level scales respectively, the difference of institute's mark height numerical value is the height differences by leveling of ground A, Z at 2, the elevation of known if wherein (such as A), the elevation of another point (such as Z) can be extrapolated by the discrepancy in elevation. If known water on schedule A Z is far away on schedule apart from target water, the height differences by leveling of A, Z cannot be directly measured at 2 with spirit-leveling instrument, now need encryption between A, Z that B, C, D are set at 2 ... etc. multiple transitional water locating tab assembly point (be called and turn a little), and two level scales are alternately placed in successively adjacent two turns of points, simultaneously spirit-leveling instrument and are successively set on the mid-way of two turns of points, measure AB, BC, CD ... the discrepancy in elevation between YZ 2, by calculating target water Z and middle B, C, D on schedule ... etc. the elevation of multiple transitional water locating tab assembly point. Therefore after every two turns of high difference measurements of point, the level scale that need to move wherein one turn of point turns a little to next, and the level scale of another turn of point only need to keep highly constant, original place horizontally rotates (be called and turn chi) makes minute cuttings just to spirit-leveling instrument.
Existing level scale is made up of rectangle chi body and the measurement of the level graduation that is labeled on chi body, and chi body bottom is plane and surrounds by wear-resisting tinsel. In order to ensure measuring accuracy, measurement of the level requires to form unique, stable point of contact (noncontact face) between the bottom surface of level scale and road surface, just needs measurement of the level special ruler pad when therefore measuring. Tradition measurement of the level special ruler pad is generally the trilateral pad that the pig iron casts, and has the leg of three consistent size below pad, has top to be the pillar (ensureing to form point cantact with scale bottom) of sphere above pad. During use, it is positioned on the pillar of (non-integral connection) chi pad to measure level scale. The main problem existed is: (1) is separated with scale due to chi pad, and when measuring, surveyor need to bend over or squat down and chi pad is first placed in ground point (be called and turn a little) every time, then is placed on chi pad by level scale; Packing up scale and chi pad respectively after measurement to be carried into new turns a little again Namely in the carrying of chi pad, arrangement etc., all bring inconvenience to survey crew, greatly have impact on the operation efficiency of measurement of the level. (2) utilization ratio of turn point on hard road surface as pbm is reduced, specifically: when turning point and be positioned at the soft matter road surfaces such as dirt road, three legs of chi pad can firmly insert in road surface, solves the problem installing level scale on soft matter road surface.But owing to turn some stability on the soft matter road surfaces such as dirt road is poor, can only use as the disposable transmission discrepancy in elevation, can not as the pbm that can utilize in the future. And when chi pad is applied to hard road surface, although ground is reliable and stable, but owing to cannot accurately determine the vertical height of chi pad top far from road surface, therefore also using turn point on hard road surface as pbm, the measurement of the level value utilization ratio turning point on hard road surface cannot be reduced. Sometimes, in order to using on hard road surface turn select as pbm or the elevation that can directly obtain Shangdi, hard road surface millet cake, survey crew simply abandon use chi pad, level scale is directly placed on hard road surface mark leveling point on. But owing to levelling pole body bottom is rectangular plane, it is difficult to form unique, stable point of contact with hard road surface, have impact on the precision of measurement of the level. Generally speaking, tradition measurement of the level special ruler pad can only meet the demand turning point, but can not meet the demand of turn point on hard road surface as pbm.
In order to solve the problem existing for tradition measurement of the level special ruler pad, number of patent application is the Chinese invention patent of 201420087665.6, disclose one " the level measuring rule pad of use can be put upside down ", it is mainly contributed is can just put, be inverted and put upside down use, not only can meet soft matter road surface or hard road surface and turn the arrangement demand a little going up level scale, also can meet turning on hard road surface simultaneously and put the demand as pbm. But when turning point and alternately occur on soft matter road surface and hard road surface, it is necessary to constantly just being put by chi pad and be inverted, chi pad can not be integrated with scale, still there is traditional measurement of the level special ruler pad because of chi pad and is separated existing problem with scale.
Summary of the invention
The present invention is to solve the above-mentioned technical problem existing for prior art, it is provided that a kind of convenience different pavement usage, effectively improve measurement of the level precision and efficiency can the level measuring rule pad of connection integrated with scale.
The technical solution of the present invention is: a kind of can the level measuring rule pad of connection integrated with scale, be provided with union lever, the lower end of union lever and spheroid are fixedly connected, and the medullary ray of described union lever is through the centre of sphere of spheroid; The outer surface cover of spheroid have can with the ball cover of spherical balling-up cephalomere, ball cover outside connects with level gear sheet, being provided with leg below level gear sheet.
It is vertical also through the centre of sphere of ball cover that the medullary ray of described leg keeps off sheet with level.
The outside surface of described ball cover is spherical, and the bottom of described ball cover forms leg through level gear sheet.
The outside surface of described ball cover is spherical, and the bottom of described ball cover is through level gear sheet, and described leg is the inverted round stage post or cone that are socketed in outside ball cover bottom.
Keep off outer edge below sheet in level and also it is fixed with auxiliary legs.
Described ball puts and is provided with drift stop.
The upper end of described union lever connects with pad, and the center of pad has the groove that notch matches with scale shape upward, is provided with scale mounting block on the sidewall of groove.
The present invention, without the need to putting upside down, settles various road surface (the hard road surface of soft soil property road surface, smooth cement pavement, soil property and rough hard tarmac etc.) upper all can stablizing and ensures that scale forms stable point of contact relative to ground by set bulb joint; When needs turn chi, also without the need to changing leg, only can being realized by set bulb joint, can be connected to one with level scale all the time, be convenient to carry, leveling process is simple, effectively improves operation efficiency. When a fixed feet is especially only set, can ensure whole chi pad level height only hard road surface and soft both matter road surfaces point, it is easy to graduation zero point correct, improve the precision of measurement of the level, meet the demand of turn point on hard road surface as pbm, improve the measurement of the level value utilization ratio turning point on hard road surface, avoid repeating work, can greatly reduce the cost of measurement of the level.
