Description
Technical field
The present invention relates to a kind of liquified natural gas conveying technologies, more specifically, it relates to which a kind of be suitable for liquid natural
The slideable supporting structure of air pipe.
Background technique
Liquid natural air pipe can generate contraction distortion in temperature change.When there is no medium in pipeline, temperature highest
It can reach+40 degrees Celsius, when being full of liquified natural gas in pipeline, temperature is minimum to can reach -163 degrees Celsius, therefore pipeline meeting
Because the larger temperature difference is deformed, maximum axial deflection generates relative displacement up to tens of milliseconds between pipeline and bracket, because
Connection type between this pipeline and bracket is slidingtype.Traditional slidingtype bracket is contacted using metal with metal slide-shaped
Formula influences pipeline sliding, the rupture of pipeline is caused when serious in the case where long-time is not used or gets rusty.Bracket is general
Fastening is arranged on hull, there is the risk of deformation after the long-time stress of hull upper bracket Support Position, once the position occurs
Deformation will change the bearing height of bracket, and the bearing height after bracket installation adjusts inconvenience, needs to reinstall bracket
Pipeline is supported, it is at high cost.And bearing height amplitude of variation is little, is visually difficult to find out.
Summary of the invention
First goal of the invention of the invention is: it overcomes liquid natural feed channel and easily gets rusty with bracket link position, shadow
The deficiency of the axial shrinkage sliding in speaking pipe road；Second goal of the invention is: overcoming hull support position and deformable duct branch occurs
When deviation occurs in support height, visually it is difficult to observe, and the deficiency inconvenient to the adjustment of the bearing height of pipeline；The present invention provides
A kind of slideable supporting structure suitable for liquid natural air pipe, liquid natural feed channel and bracket link position will not
It gets rusty, the axial shrinkage sliding of pipeline is convenient and reliable；There is deviation when deformable duct bearing height occurs in the Support Position of hull
When, it can be clearly observed, and the bearing height of pipeline can be adjusted in time, adjust easy to operate.
In order to solve the above-mentioned technical problem, the invention adopts the following technical scheme: a kind of be suitable for liquid natural air pipe
Slideable supporting structure, including liquid natural feed channel, locating rack, support base, the pedestal being fastened on hull, locating rack
Be inverted U shape structure and cover in liquid natural feed channel, locating rack opening both ends be fastenedly connected on support base, support base with
Pedestal connects, and anchor ear, anchor ear left side wall, right side wall, upside are connected with locating rack corresponding position on liquified natural gas pipeline outer wall
It is respectively mounted the sliding cushion block of arc on wall, supporting block is installed in anchor ear lower wall, sliding cushion block is placed between anchor ear and locating rack,
Sliding cushion block is bonded with locating rack, and connection backing plate on support base, supporting block is supported on backing plate, slides cushion block and backing plate is
Plastic part.
Liquid natural feed channel is supported on the backing plate on support base by anchor ear, supporting block, and support base is connect with pedestal,
Three pieces of sliding cushion blocks are set between anchor ear and locating rack, and sliding cushion block plays positioning well to liquid natural feed channel and makees
With, and sliding cushion block and backing plate are plastic part, plastic part is low temperature resistant and good heat-insulation effect, for a long time use will not give birth to
The phenomenon that rust, while plastic part and frictional resistance during metal contact slide are small, when liquid natural feed channel axial shrinkage is sliding
When dynamic, sliding cushion block is fitted in the sliding of locating rack surface, and supporting block is supported on backing plate and slides.The arc-shaped structure of cushion block is slided,
Small with the contact area of locating rack, frictional resistance is small.Liquid natural feed channel will not get rusty with bracket link position, the axis of pipeline
