Abstract
The invention aims to solve fixing and leveling problems of a small prism in a measuring process, particularly in a process of meeting an inclined steel structure. The invention provides an automatically-balanced small prism fixing and adsorbing platform. The automatically-balanced small prism fixing and adsorbing platform comprises a sleeve with a hollow inner cavity and a base with a hollow inner cavity. The upper end of the sleeve is opened and the lower end of the sleeve is sealed. The sleeve is internally provided with a separation plate. The separation plate is used for dividing the inner cavity of the sleeve into upper and lower cavities. The lower cavity of the sleeve is internally filled with heavy objects. The small prism is inserted into the upper cavity of the sleeve. An annular groove is formed in the outer wall of the sleeve. The base is made of a permanent magnet. The upper end of the base is provided with an opening. The edge of the opening is a flange. After the lower end of the sleeve is inserted into the opening, the flange is embedded into the annular groove.
Description
Technical field
The present invention relates to field of steel structure construction, specifically steel structure member is measured, is located.
Background technology
Constantly perfect along with Building technology, that industrial premises or public building are all towards the future development of " large area ", " large the scale of construction ", the vertical correction of the network frame hoisting of large span, the welding of cast steel node, steel pipe column occurs thereupon, and these all be unable to do without the surveying work of total powerstation.The continuous progress of Modern Construction Technology, engineering is also had higher requirement to the level of measuring accuracy.People often, considering how to improve the measuring accuracy of total powerstation, reducing systematic error, have but ignored another important assembly-little prism in measurement.
In reality, survey and establish in process, existing little prism fixing means is helped by a special survey crew conventionally, or sets up the fixing rear artificial leveling of tripod, and these two kinds of methods are time and effort consuming all, has hindered the convenient of surveying work and has carried out.And in fixation procedure, increased the impact of artificial uncertain factor, accidental error and people are affected to measurement result for fault.Especially need to survey when establishing some large-scale steel structure assemblies, the platform that many times all neither one is good is set up tripod, the way that employing personnel help inevitably can increase the probability of happening of accidental error, particularly operating environment is not under very desirable condition, wind is large, day irradiation shines and all can affect to people's psychology, physiology, thereby makes measurement accuracy be difficult to guarantee.
Summary of the invention
The object of the invention is to solve in measuring process, while particularly running into the steel construction of inclination, fixing, the leveling problem of little prism.
For realizing the technical scheme that the object of the invention adopts, be such, the little prism of a kind of self-poise is absorption platform fixedly, it is characterized in that: comprise a sleeve with hollow cavity, and a base equally with hollow cavity.
Described sleeve upper end is uncovered, lower end closed.Described sleeve inner has dividing plate.Described dividing plate is divided into upper and lower two cavitys by the inner chamber of sleeve.
In the lower chamber of described sleeve, fill weight.The upper cavity of described sleeve inserts for little prism.
The outer wall of described sleeve has ring groove.
Described base is made by permanent magnet.The upper end of described base has uncovered.Described uncovered edge is flange.The lower end of described sleeve insert described uncovered after, described flange embeds in described ring groove
Further, the lower chamber of described sleeve expands and forms the spheroid of hollow.
Further, described base is spliced by left half base and right half base.
The weight of further, filling in described lower chamber is grit.
Further, the xsect of described ring groove is " < " shape.The xsect of described flange is
shape.
Technique effect of the present invention is mathematical.On that described base can be adsorbed on is any (comprising inclination) steel structure member, solved the problem that measuring object is difficult to support little prism.Be more preferably, all right self-poise of the present invention, has avoided leveling repeatedly, has improved measuring accuracy.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described, but should not be construed the above-mentioned subject area of the present invention, only limits to following embodiment.Without departing from the idea case in the present invention described above, according to ordinary skill knowledge and customary means, make various replacements and change, all should be included in protection scope of the present invention.
The little prism of self-poise is an absorption platform fixedly, comprises a sleeve 2 with hollow cavity, and a base 3 equally with hollow cavity.
In embodiment, described sleeve 2 is that plastics are made.Described sleeve 2 upper ends are uncovered, lower end closed.Described sleeve 2 inside have dividing plate 203.Described dividing plate 203 is divided into upper and lower two cavitys by the inner chamber of sleeve 2.
In the lower chamber of described sleeve 2, fill weight, described weight can be grit.Referring to accompanying drawing 4, the upper end of the upper cavity of described sleeve 2 is uncovered, can insert for the lower end of little prism 1.It is the effect that described sleeve 2 has played fixing little prism 1.
The outer wall of described sleeve 2 has ring groove 202.In embodiment, the xsect of described ring groove 202 is " < " shapes.The neck place that is sleeve 2 leaves draw-in groove gap (ring groove 202), and this gap progressively dwindles to interior from outer,
Described base 3 is made by permanent magnet.When member to be measured tilt, when irregular, base 3 can be adsorbed on member.
The upper end of described base 3 has uncovered 303 of circle.Described uncovered 303 inside edge is annular flange 304.In embodiment, the xsect of described flange 304 is
shape.After the lower end of described sleeve 2 inserts described uncovered 303, described flange 304 embeds in described ring groove 202.Be that described flange 304 can coordinate with ring groove 202.Sleeve 2 be stuck in base 3 upper ends uncovered 303 in after, between the flange 304 of described annular and ring groove 202, there is certain activity space, sleeve 2 can freely swing.
Preferably, the lower chamber of described sleeve 2 expands and forms the spheroid of hollow, and described sleeve 2 bottoms become a balanced ball 201.Referring to Fig. 8, during test dip member, because the grit of filling in balanced ball 201 makes the center of gravity of whole sleeve 2 lower, sleeve 2 can be erect automatically.Further, the bottom surface of described base 3 is square, and base 3 has excessive changes of section district from certain height, starts its cross-sectional constriction from transition zone, until top.At top, foursquare center is uncovered 303.Because base 3 inside have larger cavity, balanced ball 201 can swing in certain scope.
Preferably, described base 3 is spliced by left half base 301 and right half base 302.Because left half base 301 and right half base 302 are permanent magnet, the magnetic field of its generation can allow the two be adsorbed onto together.When described left half base 301 and right half base 302 separate, uncovered 303 are also divided into two, and are convenient to the dismounting of sleeve 2.
