Three-direction inverse platform device of vibration test system

The invention discloses a three-direction inverse platform device of a vibration test system. The device comprises an inverse platform mechanism and an inverse platform point monitoring mechanism. The inverse platform mechanism is used for driving a vibration platform to rotate around an axis, and enables the vibration platform to stay at any selected station in first and second horizontal stations and a vertical station. First and second horizontal stations and the vertical station are located on the same plane. The vertical station is arranged between first and second horizontal stations. First and second horizontal stations are arranged in the same horizontal line. The inverse platform point monitoring mechanism is used for monitoring whether the vibration platform reaches any selected station in first and second horizontal stations and the vertical station when the vibration platform rotates. According to the invention, the device is simple in structure; on the premise that the vibration platform is safe, a dual horizontal platform structure can quickly inverse on left and right horizontal platforms and in the vertical direction; a user can determine inversing and staying manners of the platform body by himself or herself according to the use condition of the user; the burden of an operator can be significantly reduced; and the use efficiency of the device is improved.
