Multifunctional holder and method for tunnel inspection

Abstract

The invention provides a multifunctional cradle head and method for tunnel inspection, the multifunctional cradle head comprises a machine body and a cradle head, and the machine body and the cradle head are connected through a hollow cradle head frame; a first cylinder made of a transparent material is arranged on one side of the machine body, at least one detection element is arranged in the first cylinder, and the first cylinder can be driven by a first motor in the machine body to rotate along the axis of the machine body; the fuselage is connected with a transmission shaft of a second motor in the holder through a holder frame, and the first cylinder can rotate along the axis of the holder under the driving of the second motor; a second cylinder made of a transparent material is arranged on the other side of the fuselage, at least one detection element is arranged in the second cylinder, the second cylinder can rotate along the axis of the fuselage together with the first cylinder under the driving of a first motor in the fuselage, and the second cylinder can rotate along the axis of the holder together with the first cylinder under the driving of a second motor; according to the invention, high-precision positioning in horizontal and vertical dimensions can be realized, and the protective requirement in a specific environment is met.

Description

technical field [0001] The invention relates to the technical field of tunnel inspection equipment, in particular to a multifunctional pan-tilt and method for tunnel inspection. Background technique [0002] The statements in this section merely provide background art related to the present invention and do not necessarily constitute prior art. [0003] In urban power tunnels, power tunnel inspection robots equipped with pan-tilt camera functions have been applied in many places. The robots can realize real-time monitoring and infrared night vision functions during operation. Significant. [0004] The inventor found that most of the functions of traditional pan-tilt cameras are ball-shaped pan-tilts, or there are a few T-shaped pan-tilts. Because the internal space of the ball-shaped pan-tilts is relatively small and cramped, only visible light cameras and thermal cameras can be installed inside. The function of the imager is relatively limited; the T-shaped head expands t...

Problems solved by technology

[0004] The inventor found that most of the functions of traditional pan-tilt cameras are ball-shaped pan-tilts, or there are a few T-shaped pan-tilts. Because the internal space of the ball-shaped pan-tilts is relatively small and cramped, only visible light cameras and thermal cameras can be installed inside. The function of the imager is relatively limited; the T-shaped head expands the space in the horizontal direction, and visible light cameras and multi-function heads can be installed on the left and right, but it is not easy to realize the internal movement mechanism, and the outer shell is mostly made of sheet metal. Bulky, which hinders the expandability of its vertical space

still suffers from the barrier of space expansion

[0005] At the same time, due to the cramped internal space, the spherical head is adjusted horizontally and vertically by the same control board, and the accuracy is relatively poor. For example, adjusting the pitch of the camera cannot guarantee the horizontal positioning accuracy. The control is limited, only a few large-volume ones can be positioned in two dimensions, and the relative accuracy is improved, but it is difficult to miniaturize and adapt to the environment.
