It is adjusted, in order to ensure the installation accuracy of slideway, not only installation period is long for existing slideway installation method, and levelness inspection
Look into, pad is installed and adjustment tedious process, inefficiency.
Content of the invention
Present invention aims to the deficiencies in the prior art provide a kind of installation method of launching barge horizontal slide,
By measuring the deck level precision of slideway installation site in advance, form horizontal line, in conjunction with the installation level requirement of slideway, for
The excessive place in slideway installation site gap prepares corresponding pad and the levelness of slideway is adjusted, and can reduce slideway and install
When leveling work, improve efficiency.
The present invention is achieved through the following technical solutions this purpose：
A kind of installation method of launching barge horizontal slide, comprises the following steps：
1) determine installation site on launching barge deck for the slideway, and survey a stroke hookup wire in described installed position；
2) measure the horizontal accuracy in hookup wire region on launching barge deck, the accuracy data that measurement is obtained is remembered
Record；
3) calculated according to the accuracy data that measurement obtains and form horizontal line；
4) installation accuracy according to horizontal slide requires, the gap between analysis slideway and launching barge deck, calculates institute
The specification of the adjust pad needing；
5) the installation positioning of adjust pad, the adjust pad of dimension is installed on the correspondence position on deck, to slideway
Gap and launching barge deck between is filled with leveling using preprepared adjust pad；
6) slideway is installed, slideway is installed on deck and mounted adjust pad, using kneepiece by slideway
Both sides are welded and fixed with launching barge deck.
Wherein, described step 2) it is specially：In the range of described hookup wire, select some measurement points respectively from horizontal and vertical
To the horizontal accuracy on measurement launching barge deck, and the accuracy data that measurement is obtained records.
As preferred, described some measurement point intervals selection determination.
Wherein, the installation accuracy of described horizontal slide requires the difference in height of the top panel for horizontal slide in ± 25mm.
Wherein, all it is not welded and fixed between described adjust pad and slideway and launching barge deck.
With respect to prior art, beneficial effects of the present invention are：The installation method of the launching barge horizontal slide of the present invention,
Determine installation site on launching barge deck for the slideway first, and survey a stroke hookup wire in described installed position, then measure
The horizontal accuracy in hookup wire region, the accuracy data that measurement is obtained records, and is calculated according to described accuracy data and forms water
Horizontal line, the installation accuracy according to horizontal slide requires, the gap between analysis slideway and launching barge deck, calculates required tune
The specification of whole pad, installs slideway, and utilizes preprepared adjusting pad to the gap between slideway and launching barge deck
Piece is filled with leveling, is finally welded and fixed the both sides of slideway with launching barge deck using kneepiece, the present invention
By measuring the deck level precision of slideway installation site in advance, form horizontal line, in conjunction with the installation level requirement of slideway, for
The excessive place in slideway installation site gap prepares corresponding pad and the levelness of slideway is adjusted, and can reduce slideway and install
When leveling work, improve efficiency.

Specific embodiment
Describe the present invention below in conjunction with drawings and the specific embodiments.
Embodiment 1.
The installation method of the launching barge horizontal slide of the present embodiment, comprises the following steps：
1) as shown in figure 1, determining installation site on launching barge deck 1 for the slideway 4, and survey in described installed position
Draw hookup wire 2；
2) measure the horizontal accuracy in hookup wire 2 region on launching barge deck 1, the accuracy data that measurement is obtained is remembered
Record；
3) calculated according to the accuracy data that measurement obtains and form horizontal line；
4) installation accuracy according to horizontal slide 4 requires, the gap between analysis slideway 4 and launching barge deck 1, calculates
The specification of required adjust pad 3；
5) the installation positioning of adjust pad, the adjust pad of dimension is installed on the correspondence position on deck, to slideway 4
Gap and launching barge deck 1 between is filled with leveling using preprepared adjust pad 3；
6) as shown in figure 4, installing slideway 4, slideway 4 is installed on deck and mounted adjust pad, using triangle
The both sides of slideway 4 are welded and fixed by bracket 5 with launching barge deck 1.
As Figure 2-3, described step 2) it is specially：In the range of described hookup wire 2, select some measurement points respectively from
The horizontal accuracy on horizontal and vertical measurement launching barge deck 1, and the accuracy data of measurement acquisition is recorded.
As preferred, described some measurement points intervals select to determine, the spacing distance between cross measure point is 8.5～
11.5 meters, the spacing distance between longitudinal measurement point is 2.5 meters, corresponding with the installation site of adjust pad 3 respectively.
Wherein, the installation accuracy of the horizontal slide 4 of the present embodiment requires the difference in height of the top panel for horizontal slide 4 to exist
± 25mm, the installation accuracy of specific horizontal slide 4 can be adjusted according to actual needs.
Wherein, all it is not welded and fixed, by triangle between described adjust pad 3 and slideway 4 and launching barge deck 1
Bracket 5 is welded and fixed, and advantageously reduces adjust pad 3 and the loss of slideway 4, can be used repeatedly, low cost.
The installation method operation principle of the launching barge horizontal slide 4 of the present invention：Determine slideway 4 in launching barge first first
Installation site on plate 1, and survey a stroke hookup wire 2 in described installed position, then measure the horizontal accuracy in hookup wire 2 region,
The accuracy data that measurement is obtained records, and is calculated according to described accuracy data and forms horizontal line, according to the peace of horizontal slide 4
Dress required precision, the gap between analysis slideway 4 and launching barge deck 1, calculate the specification of required adjust pad 3, install
Slideway 4, and the gap between slideway 4 and launching barge deck 1 is filled with adjusting using preprepared adjust pad 3
Flat, finally using kneepiece 5, the both sides of slideway 4 are welded and fixed with launching barge deck 1, the present invention passes through to survey in advance
Deck 1 horizontal accuracy of amount slideway 4 installation site, forms horizontal line, in conjunction with the installation level requirement of slideway 4, pacifies for slideway 4
The excessive place in holding position gap prepares corresponding pad and the levelness of slideway 4 is adjusted, and can reduce when slideway 4 is installed
Leveling works, and improves efficiency.
