Title:
孔内調査装置
Document Type and Number:
Japanese Patent JP6648454
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an in-borehole inspection device comprising a self-travel device which can stably travel in a hole of a borehole.SOLUTION: An in-borehole inspection device comprises: a self-travel device 100 which travels in a hole of a borehole; and a control device 200 which controls travel of the self-travel device 100. The self-travel device 100 comprises: inspection devices (camera part 2, transmission device 70a, reception device 70b) for inspecting inside of a hole; a travel vehicle 1; arms (first arm 6a, second arm 6b) whose one end sides are connected to the travel vehicle 1 (chassis 1b) through a hinge part; upper hole wall drive wheels (first upper hole wall drive wheel 3, second upper hole wall drive wheel 4) disposed on the other end sides of the arms and contact the upper hole wall; and moment application means for applying a moment in a direction where the travel vehicle 1 and the upper hole wall drive wheels are separated, to the arms.SELECTED DRAWING: Figure 1
