For the Special spray coating instrument to porcelain insulator spraying room temperature vulcanized silicone rubber
Technical field
The present invention relates to the technical field of power system secondary construction, specifically a kind of for the Special spray coating instrument to porcelain insulator spraying room temperature vulcanized silicone rubber.
Background technology
For making various kinds of equipment in transformer station, as breaker, isolating switch, voltage transformer etc. keep certain insulation distance mutually, need fixing to support for the porcelain insulator of these equipment cluster parachute shapes.Use porcelain insulator to carry out insulation isolation if simple, when running into the bad weathers such as rain, snow, mist, can be easy to occur pollution flashover accident, so RTV(RTV and room temperature vulcanized silicone rubber will be brushed on porcelain insulator), prevent the generation of pollution flashover accident during the bad weathers such as rain, snow, mist.
At present, conventional porcelain insulator RTV painting way manually picks coating with common hairbrush to carry out brushing or hand-held watering can carries out single-point spraying, and its Problems existing is inefficiency, and brushing is uneven, causes the effect of antifouling work to decline.Meanwhile, due to the porcelain insulator that meeting usage quantity in transformer station is numerous, so when brushing porcelain insulator, the manpower and materials of at substantial, improve the cost of secondary construction maintenance.
In addition, when carrying out the work to porcelain insulator spraying room temperature vulcanized silicone rubber, to have a power failure to transformer station, and the time period had a power failure and time point are all that schedule ahead is good, if run into strong wind weather (cannot spraying application work be carried out at present under this weather condition) in the outage arranged, spray coating operations can be stopped because of strong wind weather, the scheduling of whole work certainly will be upset, and then upset the good power failure plan of schedule ahead, have impact on normal production and the life of enterprise and resident.
Finally, for the porcelain insulator that installation position is higher, need by high altitude vehicle coordinative construction, but due to the many local high altitude vehicle in transformer station be to enter, so add very large difficulty to the spraying application work completed in such cases.
Summary of the invention
For solving the technical problem of above-mentioned existence, the object of this invention is to provide a kind of for the Special spray coating instrument to porcelain insulator spraying room temperature vulcanized silicone rubber, the axis direction of its shower nozzle along porcelain insulator in whole spray coating operations process at the uniform velocity moves, and then makes spraying even; In addition, it is by arranging abat-vent in shower nozzle periphery, is the no longer restricted and strong wind weather of spraying application, and is fixed on equipment mounting rod, make shower nozzle vertically at the uniform velocity increase, solve the problem of work high above the ground difficulty by power drive.
The present invention solves the technical scheme that its technical problem takes: a kind of for the Special spray coating instrument to porcelain insulator spraying room temperature vulcanized silicone rubber, comprise annular deep bead, connecting plate, shower nozzle, retainer ring, bearing support and fluid pressure drive device, described annular deep bead comprises deep bead one and the deep bead two of semicircular arc, the inner arc equal diameters of deep bead one and deep bead two and be greater than the maximum outside diameter of porcelain insulator, deep bead one and deep bead two all have first fastening end and first link, first link of deep bead one and deep bead two to be hinged on respectively on connecting plate and the arc opening making the arc opening of deep bead one and deep bead two in opposite directions, circumferentially respectively in the inner side of deep bead one and deep bead two be uniformly provided with multiple shower nozzle, deep bead one with deep bead two is also respectively equipped with the shower nozzle feed tube be connected with each shower nozzle, shower nozzle feed tube is communicated with liquid feed device, described retainer ring comprises retainer ring one and the retainer ring two of semicircular arc, the interior arc dia of retainer ring one and retainer ring two is all equal with the external diameter of equipment mounting rod, retainer ring one and retainer ring two all have second fastening end and second link, the second link of retainer ring one and retainer ring two to be hinged on respectively on bearing support and the arc opening making the arc opening of retainer ring one and retainer ring two in opposite directions, the upper surface of described bearing support is vertically installed with fluid pressure drive device, and the top of fluid pressure drive device is provided with axial expansion link, and the top of expansion link rigidly fixes with connecting plate and is connected.
During use, by the Inner arc application of a surface of retainer ring one and retainer ring two on the outer circumference surface of equipment mounting rod, the second fastening end of the second fastening end of retainer ring one and retainer ring two is fastened, thus retainer ring is packed on equipment mounting rod; Equally, the first fastening end of deep bead one and the first fastening end of deep bead two are fastened, make deep bead one and deep bead two that equipment mounting rod is enclosed in the two annulus surrounded; Primer fluid hydraulic driver, along with the continuous elongation of expansion link, annular deep bead is delivered to the lower position of porcelain insulator, now opening liquid feed device makes liquid room temperature vulcanized silicone rubber transport to shower nozzle by shower nozzle feed tube and carry out spray coating operations, and after starting spray coating operations, fluid pressure drive device drives expansion link uniform speed slow to extend.
As a modification of the present invention, to be in same level at multiple shower nozzles of the uniform setting of inner circumferential of deep bead one and deep bead two and jointly to surround an annulus; The spray angle of adjacent two shower nozzles is with shower nozzle place horizontal plane for benchmark, and one is acclivitous 15 ° of angles, and another is 15 ° of downward-sloping angles.The object of such layout is, makes all shower nozzles at a time point place, can spray out an endless belt simultaneously.
As a modification of the present invention, on the retainer ring one of described retainer ring and the Inner arc curved surface of retainer ring two, attaching has one deck elastic caoutchouc, increases the frictional force between retainer ring and equipment mounting rod.
As a modification of the present invention, the top of described expansion link is connected with connecting plate by flange.
As a modification of the present invention, described deep bead one is connected with connecting plate respectively by folding with the first link of described deep bead two, and described retainer ring one is connected with bearing support respectively by folding with the second link of described retainer ring two.
The invention has the beneficial effects as follows: the multiple shower nozzles surrounding annular at the uniform velocity move together in whole spray coating operations process, ensure that the uniformity of spraying; The setting of annular deep bead makes spray coating operations no longer by the impact of strong wind weather, and spray coating operations progress no longer affects by strong wind weather, and guaranteeing to have a power failure arranges to perform smoothly according to plan, reduces the impact of producing enterprise and resident, living; And only need this device to be arranged on the position that the staff on equipment mounting rod can touch, by expansion link, shower nozzle is delivered to region, operating position, no longer need to climb and carry out operation, the use of labour is reduced.In addition, operating efficiency and work quality is also improved.
