Embodiment Construction

[0017] Such as figure 1 As shown, the present invention provides a turntable device for a wind tunnel test section, which features a disk cover 1 , a disk seat 2 , a base 3 , a steel ball 4 , an adjustment rod 5 , and a hydraulic cylinder 6 .

[0018] The base 3 is fixed on the foundation as a supporting structure, and the disc seat 2 is fixed on the base 3, and 5 rows of steel balls 4 are used as rolling bodies between the disc cover 1 and the disc cover 190° through the push and pull of the hydraulic cylinder 6. Rotation, thereby driving the test section at the top of the disc cover 1 to realize a 90° turn.

[0019] The position of the disk base 2 is adjusted by the adjusting rod 5 to realize accurate positioning of the disk base 2 on the base 3 .

[0020] By adjusting the positioning of the rod 5 and the five rows of steel balls 4, only the degree of freedom of rotation between the disc cover 1 and the disc seat 2 is limited, and there is no degree of freedom in other dire...

Abstract

The invention discloses a rotary plate device of a wind tunnel test section. The device comprises a base, a plate base, a plate cover, a hydraulic drive device and the like. The base is fixed to a foundation to serve as a supporting structure, the plate base is fixedly installed on the base, five rows of steel balls are used between the plate base and the plate cover to serve as rolling bodies, the plate cover is rotated by pushing and pulling a hydraulic cylinder, and accordingly the test section on the top of the plate cover is driven to rotate by 90 degrees. The rotary plate device is simple in structure, convenient to install and high in precision, can bear loads which are 100 T heavy, and can meet the requirement of rotating the wind tunnel test section by 90 degrees.

Description

technical field [0001] The invention relates to a turntable device for a wind tunnel test section, which belongs to the field of test devices in wind tunnel tests. Steel balls are used as rolling bodies, the degrees of freedom of rotation are limited by adjusting rods, and hydraulic cylinders are used as power sources to realize the rotation of the top of the turntable. The test section can rotate 90° safely and reliably. Background technique [0002] The wind tunnel test section is the core device of the wind tunnel test, and almost all wind tunnel tests are completed in the test section. In the initial stage of wind tunnel construction, most wind tunnels are equipped with only one or two test sections, and the test section can be replaced by walking the test section in a straight line on the track. With the development of wind tunnel test technology, it is necessary to add multiple test sections of various types in a wind tunnel to meet different test requirements. Howev...
