Exploration support with function of axial and radial cross rotation

The invention discloses an exploration support with a function of axial and radial cross rotation, and the support comprises a mobile support, an axial rotating support, a radial rotating support, and a drive device. The axial rotating support is disposed on the mobile support, and forms running fit with the mobile support. The radial rotating support and the axial rotating support form a cross, and the radial rotating support can stretch out and draw back in the axial direction. The drive device drives the axial rotating support to rotate, and drives the radial rotating support to rotate. Compared with the prior art, the method comprises the following advantages that the support provided by the invention can move horizontally through the mobile support; the axial and radial rotating supports form a cross; the drive device drives the axial and radial rotating supports to rotate, so as to achieve the continuous precise exploration of a tunnel cross section; moreover, the support can achieve the precise positio
