Abstract
Zariadenie na zamedzenie dilatácie bandáží kotlá rieši spojenie nosníkov bandáží kotlá pomocou nosného čapu opatřeného vačkou zapadajúcou do· oválných otvorov, čím sa dosiahne nepoddajné vzájomné zavesenie, ale po přesunutí čapu do druhej polohy umožňujúce dilatáciu bandáží kotlá tak ako to vyžadujú dilatačně poměry kotlá. Zariadenie je výhodné použiť pri montáži parných kotlov s membránovými stěnami výhřevných plochDevice to prevent bandage dilatation the boiler solves the connection of beams beams boilers by means of a bearing pin provided with with a cam that fits into the oval holes thereby achieving a stiff mutual suspension, but after moving the pin to the second position allowing dilatation of the boiler bands so as required by the dilatation ratios of the boiler. It is advantageous to use the device for assembly steam boilers with heating membrane walls areas
Description
Vynález sa týká zariadenia na zamedzenie dilatácie bandáží kotlá počas montáže pomocou dvoijúčelového čapu a oválných otvorov.BACKGROUND OF THE INVENTION The present invention relates to a device for preventing dilatation of boiler bandages during assembly by means of a dual-purpose pin and oval holes.
Doteraz je známe riešenie, ktoré zamedzuje dilatáciu počas montáže skladajúce sa zo vzájomnéhoí pevného prepojenia bandáží. Na prepojenie slúžia pomocné nosníky uložené nad hornú bandáž a pod spodnú bandáž a vzájomné přepojené tiahlami so závitom. Pomocou matice sa zabezpečí pevná nepoddajná poloha horizontálnych nosníkov bandáží kotlá.To date, there is a known solution that prevents dilatation during assembly consisting of a firmly interconnected bandage. Auxiliary beams placed above the upper bandage and below the lower bandage and interconnected with threaded rods serve for interconnection. The nut ensures the rigid, rigid position of the horizontal beams of the boiler bands.
Nevýhodou známého riešenia je značná spotřeba pomocného jednorázové využitého materiálu, náklady spojené s výrobou, ako aj zvýšenie pracnosti pri montáži.The disadvantage of the known solution is the considerable consumption of auxiliary disposable material, the costs associated with production, as well as the increased laboriousness during assembly.
Podstatou zariadenia na zamedzenie dilatácie bandáží kotlá podl'a vynálezu je, že nosný čap opatřený vačkou zapadá do oválného otvoru v zvislom nosníku, čím vzniká pevné nedilatačné zavesenie bandáží.The essence of the device for preventing dilatation of the boiler bandages according to the invention is that the bearing pin provided with the cam fits into the oval opening in the vertical beam, thus creating a firm non-dilatory suspension of the bandages.
Výhodou použitia riešenia podlá vynálezu je zabezpečenle stabilnej polohy, čo umožňuje zavesenie nižšie položených zvislých a tým aj vodorovných nosníkov bandáží na .najvyššie položený nosník, bez dalších nárokov na provizória, čím. sa zníži materiálová náročnost a pracnost pri výrobě a montáži.The advantage of using the solution according to the invention is that it is secured in a stable position, which allows lower vertical and thus horizontal bandage beams to be hung on the highest beam without any additional provisional requirements. This will reduce material intensity and laboriousness during production and assembly.
Na přiložených výkresoch sú znázorněné dva příklady použitia, respektive použitia zavesenia zvislých nosníkov bandáží, pričom na obr. 1A je v náryse, na obr. 1B v bokoryse, na obr. 3A a na obr. 3B v řeze znázorněné spojenie, pri ktorom je zamedzená dilatácia bandáže kotlá počas montáže a na obr. 2A v náryse, na obr. 2B v bokoryse, na obr. 4A a na obr. 4B v řeze uvolněná dilatácia počas prevádzky kotlá.In the accompanying drawings, two examples of the use or use of the suspension of the vertical bandage beams are shown. 1A is a front view of FIG. 1B in side view, FIG. 3A and FIG. 3B shows a cross-sectional view in which dilatation of the boiler bandage during assembly is prevented and FIG. 2A in front view, FIG. 2B in side view, FIG. 4A and FIG. 4B is a sectional view of the loose expansion during operation of the boiler.
Vo zvislom nosníku 2 sa pri výrobě zhotoví oválný otvor. Taký istý otvor sa zhotoví v závesnom uchu 1. V druhom závesnom uchu 3 sa vyvrtá kruhový otvor pre válcová čas- nosného čapu 4. Nosný čap 4 válcového prierezu má v časti zapadajúcej do oválných otvorov v závesnom uchu 1 a zv-islom nosníku Z vytvořená vačku, ktorá plní funkciu zamedzenia dilatácie. Aby nemohlo déjsť k samovolnému posunutiu nosného čapu 4, je jeho poloha zaistená s jednej strany podložkou 5 a závlačkou 7. Z druhej strany je stabilizovaná poloha pomocou vymedzovacej rúrky S podložky 9 a zaistená závlačkouAn oval opening is produced in the vertical beam 2 during manufacture. The same opening is made in the hinge ear 1. In the second hinge ear 3, a circular hole for the cylindrical part pin 4 is drilled. The cylindrical section 4 has a cylindrical cross-section support pin 4 formed in the oval openings in the hinge ear 1 and a cam which serves to prevent dilatation. To prevent spontaneous displacement of the support pin 4, its position is secured with one side of the washer 5 and the cotter pin 7. On the other hand, the position is stabilized by the spacing tube S of the washer 9 and secured with the cotter pin
3.Third
Po ukončení montáže, t.j. keď už nie je potřebné dilatáciu vylúčit, sa táto uvolní nasledovne: Vytiahne sa závlačka 8 a podložka 9, vyberie sa vymedzovacia rúrka B, ktorá už splnila svoju úlohu a ďalej nie je potřebná. Znovu sa nasadí podložka 9 a zaistí závlačkou 8. Nosný čap 4 sa posunie v smere „K;í tak, aby sa vačka nosného čapu vysunula z oválných otvorov vo zvislom nosníku 1 a v závesnom uchu 2. Otočením vysunutého nosného čapu 4 o ISO3 vačka přestává plnit’ svoju základnú funkciu, zamedzenie dilatácie a stává sa poistkoiu proti svojvoilnému axiálnemu pohybu nosného čapu.After completion of the assembly, ie when it is no longer necessary to exclude the expansion, it is released as follows: The cotter pin 8 and the washer 9 are removed, a spacer tube B is removed which has already fulfilled its task and is no longer required. Again, attach the pad 9 and the cotter pin 8. The support pin 4 is moved in the direction "C i to the cam bearing pin protrudes from the oval hole in the vertical beam 1 and rotating the second hinge ear protrusions of the bearing pin 4 of the cam 3 ISO it ceases to fulfill its basic function, to prevent dilatation and becomes a safety device against arbitrary axial movement of the bearing pin.
Vynález je možné výhodné použiť pri montáži parných kotlov s memránovými stěnami.The invention can be advantageously used in the assembly of steam boilers with diaphragm walls.
