FIELD: engineering of collectors for injection or drainage of gas for apparatuses for air-based gas cooling.
SUBSTANCE: device has bearing frame, on which not less than three cradle supports are mounted for supporting body of collector for injection or drainage of gas and for abutment of branch pipe connected thereto for connection to gas main, and no less than four portal supports for temporary technological holding by plane, rotation angle and position along collector for injection or drainage of gas of branch pipes with flanges for connection to chambers for inlet or outlet of gas of heat-exchange sections of air-based gas cooling apparatus adequately to position of contact surfaces of response flanges and mounting apertures in them in chamber for inlet or outlet of gas. At least two cradle supports are positioned with possible abutment of body of collector for injection or drainage of gas against them in accordance to suspension scheme, each one primarily between additional pair of portal supports, mounted below outmost and adjacent flanges of branch pipes for connection to chambers for inlet or outlet of gas. Each portal support is made with detachable beam, which is provided with device for temporary holding by plane and rotation angle of flange of appropriate branch pipe and for connection of it to body of collector for injection or drainage of gas in planned position.
EFFECT: simplified construction of building berth while providing for high precision of manufacturing of collector for drainage or injection of gas.
