Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model, the technical scheme in this utility model is carried out clearly and completely
Describe.
Refer to Fig. 1 and Fig. 2, this utility model is used for the subsidiary arm of pressure-resistance structure laser roundness measuring system wherein
One embodiment includes Magnet 1, joint 2 and measures bar 3, and described Magnet 1 is arranged on joint 2 (can between Magnet 1 and joint 2
Fix with bolt), one end of joint 2 removably connects (such as using screw locking after socket) with measuring bar 3, measures bar 3
The sidewall spacers of upper end is provided with the first reflector plate 4 and the second reflector plate 5.First reflector plate and the second reflector plate and Magnet 1 are same
On straight line, by the three-dimensional coordinate by two reflector plate calibration position of total station survey, thus it is calculated 2 institutes really
Fixed straight line and the coordinate of object under test surface joining.
Described joint 2 can use aluminium alloy to make, and measures bar 3 and uses fiber rod to make as raw material.First reflector plate 4
Can be fixed on measurement bar 3 by mosaic mode with the second reflector plate 5, can preferably protect reflector plate, and cost-effective.
Compared with rotating target, use reflector plate economical and practical, degree of precision can be kept simultaneously, have longer service life.Magnet 2 He
Measuring bar 3 can use bolt and viscose glue dual mode to fix, solid and reliable, durable in use.
This utility model applies to assist total powerstation to measure, it is contemplated that the weight of total powerstation, support and auxiliary products
With the problem such as the configuration that volume also has survey crew, the material measuring arm be there are certain requirements, will make to measure arm and be easy to take
Band, it is simple to fixing, is not likely to produce deformation, it is ensured that certainty of measurement.Therefore measurement arm is divided three parts to be designed by this utility model
Assemble, be Magnet 1, joint 2 and measurement bar 3 respectively.
In industrial circle, product is to be processed using iron and steel as raw material mostly, and particularly shipbuilding industry can claim
Most advanced and sophisticated industry for industrial circle.Owing to iron and steel is at the extensive application of shipbuilding industry, bottom the most of the present utility model Magnet
As raw material, use the strong adsorption function of Magnet itself to make measurement arm to be preferably fixed on steel plate, landing will not be produced
Etc. problem, and there is no concern that the problem that crystallized ability dies down in time, the permanent usability of product can be ensured.
Aluminum alloy material contact density is low, but strength ratio is higher, and near or above high-quality steel, plasticity is good, can be processed into each
Kind of section bar, has excellent electric conductivity, heat conductivity and a corrosion stability, and low price.Due to this high intensity of aluminium alloy and can
Plasticity, uses it to make joint 2, can be as Magnet and the connection member measuring bar 3, and will not measure arm because of fixing or peculation is to produce
The shape that changes and affect certainty of measurement.
Measuring the bar 3 major part as measurement arm, corrosion-resistant to its material, intensity is high, the spies such as the life-span is long, light weight
Property, after multiplex screening, final choice carbon fiber rod is as raw material.Carbon fiber rod is lightweight, and intensity is high, its proportion
For 1.4-1.5g/cm, being only 1/4th of steel, intensity is tens times of plastic, and therefore high-strength light is carbon fiber
One of distinguishing feature of composite.Carbon fibre composite is the most corrosion-resistant, aging resistance, and service life is long, and safety is good
Characteristic.
During measuring steel structure, the position set up due to total powerstation is according to the situation, because of
The position that this blind area measuring point occurs has randomness, then the degree of crook of measuring point place steel plate is uncertain, it is contemplated that this
Situation, can separately design different measuring arm joint form, and the length measuring bar on this basis also has several change, can be according to existing
Field situation selects most suitable subsidiary arm.
As in figure 2 it is shown, about 2 points two parts of one of them joint, the cylindrical structure of upper part and the one end measuring bar 3 can
Dismounting connects, and lower part drum diameter is more bigger than upper part center drum, and lower part cylinder is provided with installed surface 6, and Magnet 1 is installed
On installed surface 6, Magnet 1 place plane and the angle measuring bar 3 place axis can be arranged as required to, and Fig. 2 show 30 °,
Wherein installed surface 6 is cut sth. askew by lower part cylinder and is formed, and so measurement to curved surface has obvious action, can improve measurement essence
Degree, the measurement small angle measurement arm to marginal area, can preferably complete to measure.
Please continue to refer to Fig. 3 and Fig. 4, in another embodiment, installed surface 6 is positioned at the bottom surface of bottom cylinder, and Magnet 1 is installed
On installed surface 6, Magnet 1 place plane is 90 ° with the angle of measurement bar 3 place axis.
This utility model is a kind of subsidiary arm based on pressure volumetric laser circularity analysis design.Pressure volumetric laser circularity
Analyser by measure control station, total powerstation, magnetic rotate target, reflector plate, subsidiary arm, data wireless transport module and
Row is measured the hardware such as on-line equipment and is constituted.Pressure volumetric laser circularity analyser can be widely applied to boats and ships post pyramidal structure and pot
The radial direction of stove etc. are pressure cylindrical vessel just amount of deflection, the isoparametric measurement of section circularity and evaluation.
This utility model is primarily adapted for use in large cylindrical conical shell roundness measurement, and space can be divided by this large-scale component
It is slit into the local space with special role.In this small space, need to coordinate subsidiary arm just can complete data acquisition
Collection, the structure therefore measuring arm wants simple, it is simple to being used for multiple times, the measurement arm of labyrinth cannot normally use, and on the contrary can
Affect certainty of measurement.
This utility model structure is relatively simple, does not has the particular/special requirement of harshness to processing and fabricating, it is possible to ensure higher survey
Accuracy of measurement, even if being deformed after life-time service the most not affecting, only need to re-scale.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to
In this, any belong to those skilled in the art in the technical scope that this utility model discloses, the change that can readily occur in
Change or replace, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with power
The protection domain that profit requires is as the criterion.
