PROBLEM TO BE SOLVED: To provide a wall climbing device that can change necessary suction force in conformity to irregular shapes of suction surfaces such as wall surfaces, and can climb while being suctioned even if being in a various surface state.SOLUTION: A wall climbing device includes a decompression chamber 11 formed in the lower surface of a base body 10, motor fans 13, 14 for forcibly exhausting the inside of a decompression chamber and holding the decompression, and two or more climbing wheels 20 arranged in the base body and moving the base body. Two or more motor fans are arranged in the upper part of the decompression chamber. An upper opening in communication with an inlet of the two or more motor fans is formed in the upper side of the decompression chamber. A flexible member 12 comprising a semi-independent semi-continuous bubble type low-tension compression sponge formed of two or more suction openings divided in response to the number of motor fans is arranged in the lower side of the decompression chamber coming in contact with the suction surface. A shunt member formed of two or more ventilation passages corresponding to the number of motor fans is arranged between the flexible member 12 and the upper side of the decompression chamber. The inlets of individual motor fans are brought into communication with two or more suction openings through the ventilation passage of the shunt member.SELECTED DRAWING: Figure 1
【課題】壁面等の吸着面の凹凸形状に合わせて必要な吸着力を変化させ、多様な表面状態であっても吸着させて走行することができる壁面吸着走行装置を提供する。【解決手段】基体10の下面に形成された減圧室11と、減圧室内を強制排気して減圧保持するための電動ファン13、14と、基体に配設され基体を移動させる複数の走行輪20を備える。減圧室の上部には複数個の電動ファンが配設され、減圧室の上側には、複数個の電動ファンの吸入口に連通する上側開口が形成され、吸着面と接する減圧室の下側には、電動ファンの個数に対応して分割された複数個の吸引開口が形成された半独立半連続気泡型の低応力圧縮スポンジからなる柔軟性部材12が配置され、柔軟性部材12と減圧室の上側との間には、電動ファンの個数に対応した複数の通風路が形成された分流部材が配設され、個々の電動ファンの吸入口と複数個の吸引開口とを分流部材の通風路を介して連通させる。【選択図】図1
