Description
Technical field
The utility model relates to a kind of devices more particularly to one of bridge flexible cable outer surface rotary spraying corrosion-inhibiting coating
The outer surface rotary spraying polyureas device of the kind long flexible cable of bridge.
Background technique
Polyurea materials have excellent physicochemical property, such as flexibility, wearability, ageing-resistant and corrosion resistance, or even in pole
Also there is no crackings, dusting in the environment of end, if applying polyurea materials in the protection of the outer surface of bridge cable, can incite somebody to action
Drag-line puts on one layer of special protection coat, can greatly improve the service life of drag-line, and polyurea materials and bridge cable are pressed
Combination is pioneering using at home and abroad belonging at present in this way, and various aspects do not have referential experience.Conventional polyureas is sprayed on
In column class part appearance surface construction, usually there are 4 kinds of spraying methods:
The first: using artificial multi-angle, repeatedly number realizes the spraying of drag-line outer surface, and this mode, which sprays major defect, is
Automatic spraying is not used, hand spray is easily accidentally sucked by human body, and artificial work amount is big, it is difficult to realize and produce in enormous quantities；By
In hand spray by operative employee's qualification, the factors such as emotional change influence, in addition the quick surface drying characteristic of polyurea materials itself, applies
Layer quality conformance is difficult to ensure.
Second: shorter drag-line (several meters to more than ten meters) being subjected to rotation support, spray gun is fixed on around cable body along drawing
Rope moves axially to reach the rotary spraying purpose of drag-line outer surface.This mode is only adapted to shorter drag-line, because this
The short drag-line of sample easy to accomplish can rotate, and be able to satisfy certain rotational speed, but such spraying method still can be
The bad spraying of the support zone of drag-line, it is necessary to repair support zone using secondary spraying, be easy to produce faying surface, influence
Production efficiency and presentation quality.Simultaneously for longer flexible cable, tens meters of even several hundred rice, flexible cables are just difficult to rotate
Get up, even if rotation can not meet the rotation speed of spraying process requirement by force, it is clear that this mode is not able to satisfy long flexibility
Drag-line rotary spraying production requirement.
The third: being distributed in spray gun angle progress outer surface spraying different on the circumference of drag-line outer surface using more.This
Kind mode greatest problem is that the presentation quality and uniformity in junction of spray-on coating are difficult to ensure, while polyureas sprays occasion
One flush coater can only supply a pressure and flow spray gun, more that spray gun must be used more flush coaters, and cost is caused to increase
Add.And the flow and air pressure consistency of multiple devices are also difficult to ensure, cause the appearance of coat quality finally sprayed that cannot expire
Foot requires.
4th kind: being fed intermediate link in the polyureas spraying process of original maturation, install a polyureas A additional, B component is fed
Rotary joint carries out rotation feed, to solve the problems, such as that unidirectionally persistently winding rotation causes to fall short of feeding pipe, works as flexibility
Drag-line moves forward, and spray gun carries out the rotary spraying to flexible cable under the drive of rotary joint (referring to attached drawing 4).But by
What it is in spraying is drag-line outer surface, and the central bore that drag-line has to pass through rotary joint is just able to achieve the rotation to drag-line outer surface
Spraying.The central bore diameter of the case where can achieve 200mm according to conventional cable diameter, this rotary joint has to be larger than
200mm could facilitate drag-line to pass through rotary joint, in conjunction with the surface drying time and desired coating layer thickness of spray polyurea material, rotation
Adapter, which needs to reach certain revolving speed, just can guarantee coating thickness and apparent mass, will lead to the close of the rotary joint in this way
Seal linear velocity is high.It is improved, bridge cable demand according to the mechanics of polyurea materials, physical property with the increase of spray pressure
The mechanics of polyurea materials, the ideal spray pressure under physical property must reach 12MPa or more, in high linear speed and high spraying pressure
Under the comprehensive function of power, the surface of sealing element will generate a very high temperature, under the composite factor of this " three high ", rotation
The seal life of connector just substantially reduces, and sealing element is easy failure, and polyureas A, B component raw material are easy for leaking, due to polyureas
The moisture sensitive and particularity of materials A component, slightly slight leakage are exposed in the air with moisture or meet just with B component
It will lead to crystallization, rotary joint is stuck and is not able to rotate, this rotary spraying work that drag-line outer surface is carried out using rotary joint
Skill poor reliability under the technical conditions in sealing industry at present, it is difficult to apply the formal production occasion in mass.
Above four kinds of spraying methods are all difficult to solve the problems, such as long flexible cable outer surface rotary spraying polyurea materials.
Summary of the invention
