Azimuth-pitch movement two-shaft seat rack

Abstract

The invention discloses an azimuth-pitch movement two-shaft seat rack which is provided with a circular rail. The vertical axis of a vertical column is at the center of the circular rail, and the vertical column is connected to a rotation platform through the first rotation pair with a horizontal axis and is connected to a rack or ground through a second rotation pair with a vertical axis. The upper ends of two connection rods are connected to the rotation platform through hookjoints, and a sliding mechanism and the lower end of the connection rod are connected by using a composite hinge with three degrees of rotation freedom. According to the azimuth-pitch movement two-shaft seat rack, 0-degree to 90-degree pitch movement and -180-degree to 180-degree azimuth movement can be realized, external equipment can be a radar antenna, an astronomy radio camera, a camera, a sunlight reflector, and a solar energy sailboard. The structure is simple, the operation is convenient, and the problems of a heavy structure, a large driving power, and driving joint error accumulation of a traditional series connection type azimuth-pitch seat frame for large-scale apparatus equipment with a large quality are solved.

Description

technical field [0001] The invention belongs to the technical field of large-scale instrument mounts, in particular to an azimuth-pitch motion two-axis mount. Background technique [0002] At present, the azimuth-tilt mount is a simple two-axis rotation mechanism, which is used to support various instruments or equipment and perform rotation around two mutually perpendicular axes (one is a vertical axis and the other is a horizontal axis). The rotation around the vertical axis changes the orientation angle of the supporting device, which is usually called azimuth motion; the rotation around the horizontal axis changes the levelness of the supported object, which is usually called pitch motion. The traditional azimuth-tilt mount usually adopts the mature structural form as follows: two mutually perpendicular rotating shafts (revolute joints) that can be actively controlled form an azimuth-tilt mount. Each shaft joint is driven by a servo motor and a reduction gear train. Th...
