Description
Technical field
A kind of invar bar code ruler measurement auxiliary mould is the utility model is related to, for the measurement of the level.
Background technology
It is typically all directly to use that invar bar code ruler currently used for the measurement of the level, which is also referred to as invar wire, but the side directly used
There are the following problems in formula practical application：
1st, in such as high-speed railway subgrade settlement observation, directly invar wire is positioned on measurement component, usually measurement
Component is galvanized pipe, this form cannot meet the requirement on " levelling rod should be positioned over top dome, i.e., unique apex "；
2nd, in frequently measurement operation, invar wire is placed directly on measurement component, and invar wire is produced to same
Abrasion and the degree worn to the generation of a pair of of invar wire are unequal, and causing a pair of of invar wire zero point, equal difference does not transfinite, GB 12897-
Limit value is 0.1mm in 2006 national first and second order leveling specifications.
3rd, in first and second order leveling operation, often there is height of sighting line and be unsatisfactory for requiring, but with limit value again very close to；
Rising and falling, more measurement of the level section is very inconvenient.
Utility model content
The utility model is to avoid the shortcoming present in the above-mentioned prior art, there is provided a kind of convenient for disassembly and assembly, practical
Property it is strong, of low cost, low-loss invar bar code ruler measurement auxiliary mould can drop.
The utility model adopts the following technical scheme that to solve technical problem：
The utility model invar bar code ruler measurement auxiliary mould is structurally characterized in that：It is removable in the bottom of invar bar code ruler
Supporting station is installed, dome-type pedestal is set in the bottom surface of the supporting station, the hemispherical pedestal is by hemispheroidal circular top
Face and the bottom surface of supporting station consolidate, and remove hemispheroidal bottom spherical crown, the hemisphere is formed sphere outer circumference surface and bottom
Facial planes；The invar bar code ruler is supported on using the sphere outer circumference surface on the mouth of pipe of measurement component, or described in utilization
Base plane is supported on measurement foot pin.
The design feature of the utility model invar bar code ruler measurement auxiliary mould is lain also in：In the two sides of the supporting station
Side block is provided with, the top surface of the supporting station is formed as groove surface, the bottom inlay card of the invar bar code ruler is in the groove
In face.
The design feature of the utility model invar bar code ruler measurement auxiliary mould is lain also in：Magnetic is inlayed in the supporting station
Iron, ferromagnetic attraction force is formed using magnet between supporting station and invar bar code ruler, ensures the top surface and invar bar code ruler of supporting station
Bottom surface for fitting.
Compared with the prior art, the utility model has the beneficial effect that：
1st, for the utility model as auxiliary mould, its is convenient for disassembly and assembly, highly practical, of low cost；
2nd, the utility model sets dome-type pedestal in the bottom of supporting station, is mutually tied with base plane with sphere outer circumference surface
Structure, can be matched with measurement component, can also be matched with measurement foot pin, strong applicability.
3rd, magnetic attraction is used between supporting station and invar bar code ruler, makes the top surface of supporting station and the bottom of invar bar code ruler
Face is fitting, ensures measurement accuracy.
4th, the utility model avoids invar wire and directly acts on foot pin or other measurement components, can effectively protect price
Higher invar wire is without damage, it also avoid wearing.

Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, invar bar code ruler measurement auxiliary mould is at the bottom of invar bar code ruler 4 in the present embodiment
The removable installation supporting station 2 in portion, sets dome-type pedestal 3, hemispherical pedestal 3 is by hemispheroidal circle in the bottom surface of supporting station 2
The bottom surface of shape top surface and supporting station 2 consolidates, and removes hemispheroidal bottom spherical crown, make hemisphere formed sphere outer circumference surface 3a and
Base plane 3b；Invar bar code ruler is supported on using sphere outer circumference surface on the mouth of pipe of measurement component, or utilizes the bottom
Planar support is on measurement foot pin 5.
In specific implementations, the two sides of supporting station 2 are provided with side block 1, the top surface of supporting station 2 is formed as groove surface,
On the one hand the bottom inlay card of invar bar code ruler 4 can ensure that supporting station 2 stablizes branch for invar bar code ruler 4 in groove surface
Hold, gear shield is on the other hand formed in both sides to the base of invar bar code ruler 4 using side block 1；The embedded magnet in supporting station 2, profit
Ferromagnetic attraction force is formed between supporting table 2 and invar bar code ruler 4 with magnet, ensures the top surface and invar bar code ruler 4 of supporting station 2
Bottom surface is fitting, effectively avoids the measurement error caused by not being bonded.
In specific implementation, supporting station 2 and ball-type pedestal 3 and side block 1 can use lathe overall processing to be molded, and support
Thickness is inlayed in platform 2 and is the magnet of 0.5cm, and ensures the flatness of the top surface of the supporting station after embedded magnet 2；Utilize ferromagnetic suction
Power adsorbs supporting station 2 on the base of invar bar code ruler 4.In specific implementation, the base plane of hemispherical pedestal 3 can be set
Radius is 1cm, and hemispheroidal radius is 2cm, i.e., the radius of hemispheroidal circular top surface is 2cm.
In use, auxiliary mould is adsorbed on the base of invar bar code ruler 4 using supporting station 2, in measurement of the level circuit
In, it is placed on using the base plane of dome-type pedestal 3 on measurement foot pin 5 during turning point；When measuring galvanized pipe component, utilize
The sphere outer circumference surface of dome-type pedestal 3 is supported on the zinc-plated mouth of pipe.
