Description
Technical field
The present invention relates to technical field of fastening, and in particular to a kind of spray coating heat preservation layer bracing means for tank body and its
Construction method.
Background technique
Currently, spraying polyurethane heat-insulation system has been used to the fuel tank and other low temperature tank bodies of spot ship.However,
Low temperature when loading cryogenic cargo due to tank body by the stress significantly increased between spray coating heat preservation material and tank body and influences it
Between adhesive property, thus ultimately cause heat-insulation system from tank surface be detached from.Surface break-off may cause poly- simultaneously
The cracking of urethane thermal insulation material and layering eventually affect entire heat-insulation system performance.To avoid this problem, take now
Usual way is to increase the grid cloth of different materials after spray coating heat preservation material or spray coating heat preservation reach final thickness to tie up
Hold whole system.But this design can bring some problems, and increase grid cloth will affect polyurethane material and exist in spray coating heat preservation
Perpendicular to the tensile strength on grid cloth direction, while causing the separation between polyurethane；Increase in spray coating heat preservation material outermost layer
Add grid cloth that surface protecting material loss will be caused excessive and influences appearance.
Summary of the invention
The purpose of the present invention is to solve the above-mentioned problems and provides a kind of spray coating heat preservation layer reinforcing dress for tank body
It sets and its construction method, the bracing means is easy for installation, appearance investigation, while can effectively avoid spraying polyurethane since low temperature is made
At disengaging.
The purpose of the present invention is achieved through the following technical solutions:
A kind of spray coating heat preservation layer bracing means for tank body, the bracing means include bolt and fastener, the bolt
The outside of tank body wall surface is set, the fastener is arranged on insulating layer, including integrally formed head, cylinder and tail portion,
The head is provided with empty slot, and empty slot inner wall is equipped with the internal screw thread matched with bolt, and the tail portion is fixedly connected with insulating layer.
Further, insulating layer stratiform setting, the insulating layer close to tank body wall surface are provided with and can accommodate the logical of fastener
Hole, the length of the fastener are greater than the insulating layer of single layer, and the tail portion of the fastener is cylindrical body, are equipped with external screw thread, pass through
Nut is fixed on insulating layer.
Further, the nut is selected from one of hexagonal (hexagon)nut, circle nut, square nut or tapered cup nut or a variety of.
Further, washer is equipped between the nut and insulating layer.It is further preferred that the washer is rubber pad
Circle.Washer can better ensure that nut and insulating layer closely connect, and prevent nut from damaging to insulating layer.
Further, the head sectional dimension is greater than cylinder, and cylinder sectional dimension is greater than bolt, can save fastener
It is easily operated when preparing material consumption, and the head of fastener being attached with bolt.
Further, the head of the fastener and barrel outer surface are smooth, are easy to the processing of insulating layer through-hole, the head
Portion connects with cylinder circular arc.
Further, the bolt and tank body wall surface are to be welded to connect.Shadow caused by armor plate strength original for tank body
It rings near nothing, while electric resistance welding is easy for construction, speed is fast, reliable in quality.
Further, the bracing means is multiple, and setting is spaced between tank body wall surface and insulating layer, to guarantee to cover
The insulating layer covered in tank surface can be fixed.
A kind of construction method of the spray coating heat preservation layer bracing means for tank body, specifically: bolt is fixed at tank body
On the outside of wall surface, the head of fastener is connected by the tail portion of securing member and insulating layer with bolt later.
The present invention uses main body of the fastener as bracing means, and rely on head is threaded io the welding of tank body wall surface
Bolt, thus mechanically reinforce polyurethane coating adiabator layer, so that polyurethane spraying material is fixed on tank surface
To form a complete heat-insulation system to avoid the cracking that may occur and layering.
In addition, the present invention also respectively tests the reliability of bracing means and applicability in terms of following two
Card: the first finite element stress analysis simulated in low-temperature circulating for tank body；Second application realistic model accelerates cooling experiment
To simulate the stress being subjected to of tank body in extreme circumstances.
Loading temperature sensor is to monitor cooling experimental temperature variation on thickness of the thermal insulation material every 100mm.It is first
It is first cooled down with liquid nitrogen, cooling rate is -40 °/h (from the interior testing temperature sensor speed control of model), until from room temperature
- 180 ° are reduced to, keeps the temperature at-160-180 ° of 48 hours later.Finally accelerated using the compressed air of heating
Warming temperature, warm rate reach 40 °/h until reaching room temperature.Under the above situation, the present invention is used for the spray coating heat preservation layer of tank body
Bracing means safety coefficient with higher.
Compared with prior art, the invention has the following advantages:
One, use scope is wide: being applicable to load flow container and fuel tank that various cargos have insulating layer.It simultaneously can also root
Optimal solution is made according to flow container of different shapes and fuel tank.
Two, appearance investigation: the present invention can improve not the construction for influencing polyurethane coating, without in protective polyurethane layer outer layer
Add additional structure.
Three, mitigate cost: the present invention will greatly reduce the cost of existing system.Existing system need to be by entire sprayed surface
It is reinforced, to expend greatly artificial and Master Cost in construction.The present invention passes through leading finite element analysis, portion
Quartile, which is set, carries out mechanical consolidation to reduce Master Cost in installation process and artificial.
It is four, safe and reliable: in R&D process, to pass through the analysis of multiple simulation cooling cycle and finite element, it can be ensured that
The program is suitable under a variety of different situations.Safety coefficient with higher.
