It is particularly important that cable guide pipe installation positioning is carried out in the process fast and accurately.Cable guide pipe installation positioning is broadly divided into two steps：Preliminary survey：?
Setting-out goes out the relative position of cable guide pipe on stiff skeleton, and cable guide pipe is lifted to stiff skeleton, by cable guide pipe setting-out on skeleton
Mark point, line on position and cable guide pipe align, and guarantee angle, line style that cable guide pipe is tentatively installed.Cable guide pipe is existed with guide chain
Vertical, horizontal position is temporarily fixed on skeleton.Accurate measurement：Point position is marked in cable guide pipe upper and lower opening in advance, utilizes measuring point and rope
Catheter center's line relative positional relationship, extrapolates measuring point design coordinate, and precise measurement measuring point actual coordinate is sat by the way that measuring point is practical
Mark and design coordinate pair ratio, finely tune cable guide pipe, until cable guide pipe reaches design position.
Existing accurate measurement process has certain limitation, can not direct accurate measurement cable guide pipe position of center line, once cable guide pipe
Machining accuracy is poor or error occurs in label point position, the installation positioning of cable guide pipe with and just will appear deviation.This is practical new
Type provides a kind of cable guide pipe center line positioning measurement supplementary base, including positioning rule, positioning support plate, fixed vertical plate, positioning rule
Upper mark longitudinal center graduation mark, ruler plate transverse direction graduation mark, ruler plate transverse and longitudinal graduation mark punctuate, utilize positioning support plate and positioning rule
Upper label positions cable guide pipe center line, and overcoming conventional cable guide pipe accurate measurement in the process can not direct accurate measurement cable guide pipe position of center line
Defect, avoid the installation deviation as brought by cable guide pipe machining accuracy or point position error, it is fixed to improve cable guide pipe
Position installation accuracy is worth promoting in engineering practice.
Utility model content
The utility model is directed to the demand and shortcoming of current technology development, provides a kind of cable guide pipe center line positioning survey
Supplementary base is measured, fabrication and installation are very simple and convenient, improve cable guide pipe location and installation precision, are worth pushing away in engineering practice
Extensively.
A kind of cable guide pipe center line positioning measurement supplementary base, including positioning rule, positioning support plate, fixed vertical plate,
Wherein arc plate, arc boom plate, camber board group are at semicircle positioning support plate, arc boom plate top margin and cable guide pipe internal diameter phase
Together, through-hole is opened up among camber plate, fixed vertical plate passes through through-hole, and front and back vertically connects two blocks of positioning support plates, two pieces of positioning branch
The arc boom plate midpoint of fagging opens up groove, the horizontal positioned positioning rule of accommodating in groove, and positioning rule top surface label is longitudinal
Center graduation mark, lateral graduation mark and transverse and longitudinal graduation mark punctuate, for positioning cable guide pipe center line.
The length of positioning rule is greater than the distance between two blocks of positioning support plates in the supplementary base.Easily facilitate survey
Amount.
Anti-slip layer is attached in the supplementary base on the outside of arc plate.Prevent supplementary base from skidding in cable guide pipe.
Longitudinal center's graduation mark of positioning rule top surface label different colours, lateral graduation mark and cross in the supplementary base
Vertical graduation mark punctuate.
The utility model has an advantageous effect in that compared with prior art：
Including positioning rule, positioning support plate, fixed vertical plate, longitudinal center's graduation mark is marked in positioning rule, ruler plate is laterally carved
Line, ruler plate transverse and longitudinal graduation mark punctuate are spent, using label positioning cable guide pipe center line in positioning support plate and positioning rule, is overcome often
Advise during cable guide pipe accurate measurement can not direct accurate measurement cable guide pipe position of center line defect, avoid due to cable guide pipe machining accuracy
Or installation deviation brought by point position error, cable guide pipe location and installation precision is improved, is worth promoting in engineering practice.
