Ultra-large electrically-driven soundproof door structure of wind tunnel anechoic chamber plenum chamber

Abstract

The invention relates to an ultra-large electrically-driven soundproof door structure of a wind tunnel anechoic chamber plenum chamber. The ultra-large electrically-driven soundproof door structure comprises a door frame (civil engineering structure), a door body assembly, a door body bottom beam, electrically-driven assemblies and a door slot soundproof sealing assembly. The door body assembly is fixedly installed on the door body bottom beam, a group of electrically-driven assemblies are correspondingly installed on the two sides of the door body bottom beam in the moving direction of a door, and the door slot soundproof sealing assembly is installed on the door frame. The door body bottom beam comprises a multi-section box beam formed by welding steel plates, and carrying small tanks are correspondingly arranged on the two sides of the box beam, the door body assembly is a main frame formed by mutually and fixedly connecting door body main stand columns and door body main cross beams, and small sashes are formed by fixedly connecting door body auxiliary columns and door body auxiliary beams between main frames formed by the door body main stand columns and the door body main cross beams. When the ultra-large soundproof gate is closed, the pneumatic and acoustic test performance requirements of a large aircraft in an anechoic chamber can be met, and when the gate is opened, the passing requirements of large test equipment and the large aircraft can be met.

Description

Technical field [0001] The present invention relates to the field of sound insulating door, and is specifically a sound door structure of a super-large electrical drive of a wind tunnel. Background technique [0002] At present, there are more than 10m or less signs, and the super large sound insulation door is limited by factors such as processing technology, installation conditions, sound insulation seals and accuracy requirements. There is almost no more than 15m level of exclaim in China. Door products, especially wind tunnel resident room parking room, a pneumatic, acoustic performance floor test of large aircraft (such as large domestic passenger aircraft, military machine, rocket, etc.), but the specifications of the existing acoustic doors are pneumatic and acoustic Performance test has caused certain limits. [0003] The existing large sound insulating door has adopted the door structure plan for the on-site security. If the overall field of the parquet hall, the parking...
