Description
Technical field
The present invention relates to the installation field of locating technology of ballast for cruising piping, the installation of a kind of ballast for cruising piping
Positioning assisting tooling and installation and locating method thereof.
Background technology
Along with the technique lifting requirement of extensively implementation and minimizing or cancellation adjustment pipe (gathering pipe) of boats and ships PSPC specification,
The advance fitting-out required precision of ballast for cruising piping is more and more higher.As a example by Mobil LNG series ballast for cruising piping, it builds difficulty
Point can be summarized as following three points: first, it is desirable to prepackage installment work settles at one go, and the later stage cannot adjust.Ballast tube branch pipe wall
Employing plastic-coated is protected, and coating layer fusing point is the lowest, and scene cannot carry out hot worked adjustment and amendment to pipe.Meanwhile, Mobil LNG
Ship performs PSPC specification, it is desirable to the crossing cabin outfititem of ballast tank was the most all welded in place in the advance fitting-out stage, in total group stage
Carry out docking of ballast line house steward and crossing cabin arm, no longer carry out the fire operation in ballast tank region.Second, piping during prepackage
Positioning difficulty is high.Owing to the glass reinforced plastic pipe house steward of ballast line should not be pre-buried in the segmentation stage, therefore the arm of piping and support
Outfititem does not has the centering reference of material object when installing and check.3rd, it is desirable to the required precision that piping is installed is high.In the always company of group
When connecing, be responsible for arm between do not adjust pipe, be mounted directly butterfly valve, valve two ends respectively with bolt to wearing connection, this is to butterfly valve
The piping installation accuracy at two ends requires the highest.Moreover, the same upper connection of ballast house steward has two sections of arms and installs many
Individual support, is responsible for and installs in last, belongs to the situation of " a branched fixed master ", needs the size of each pipe Xi part to be guaranteed simultaneously.
Therefore, certainty of measurement when positioning pipe advance fitting-out part proposes the highest requirement.
But, relatively big with the difficulty that existing conventional tool is measured at the scene, result in pipe fittings to a certain extent and be difficult to pacify
Dress precisely, occurs in that situation about doing over again in a large number.The difficult point of in-site measurement includes: 1. due to pipe hollow, positions advance fitting-out arm
Flange center or bolt hole center are relatively difficult.2. there is multiple tracks rib, strengthen version or big weld seam in scene, need during measurement by
Section is measured cumulative, causes measuring cumulative error bigger.3. the requirement to flange face corner and the positioning precision of total pipe holder is higher,
But in-site measurement is the most difficult.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the present invention provides the installation location auxiliary work of a kind of ballast for cruising piping
Dress and installation and locating method thereof, it is possible to control the multinomial location dimension of multiple advance fitting-out arm well fast accurate, including: arm
Between open a grade spacing dimension, arm height dimension, the corner size of arm flange face and flange broken face size, improve arm
The positioning precision of advance fitting-out part, it is ensured that in follow-up work, main line can be installed smoothly with each arm and be connected.
The technical solution of the present invention is as follows:
