A traveling carriage equipped with a traveling means to travel on and along a surface of an object. A frame of the traveling carriage is composed of two divided frames to the right and to the left in the forward traveling direction, one frame having an arc-shaped sliding rail which forms an arc viewed from the side. The arc-shaped sliding rail is supported by a sliding guide installed onto the other frame as to be capable of sliding along the arc-shaped sliding rail.

A surface treating device includes a tubular blasting case member having a main open face and a sub-open face. A suction-adhering seal engages the blasting case to seal a space defined between the blasting case and the surface of the object being treated. Sand, water, or other abrasive material is ejected through a nozzle and the blasting case, toward the surface being treated. A flat belt or plate, which includes a nozzle opening, engages the sub-open face of the blasting case and covers the blasting case opening. A surface of the flat belt member is brought into sealing contact with a surface of the sub-open face due to a difference in pressure between an inside and an outside of a pressure reduction space such that the blasting case opening is completely covered and sealed while the flat belt member reciprocatingly moves along with the nozzle.

A rotary travelling device comprising a main supporting member rotatably around a first axis substantially perpendicular to a travelling surface, a subsidiary supporting member mounted on the main supporting member for free rotation around a second axis substantially parallel to the first axis, a rotary disc mounted rotatably on the subsidiary member, and a driving means for rotating the rotary disc. The central axis of rotation of the rotary disc is not perpendicular but inclined to the travelling surface, and the under surface of the rotary disc comes into inclined contact with the travelling surface. The device is further provided with means for rotating the subsidiary member around the second axis according to the rotation of the main supporting member around the first axis.

A device capable of suction-adhering to a wall surface by the pressure of an ambient fluid, and of moving along the wall surface. The device includes a pressure receiver housing made of a rigid or semi-rigid material; a plurality of wheels or endless tracks secured to the housing so as to make contact with the wall surface; a partition connected to the housing and having a free end adapted to make contact with the wall surface, at least the free end being made of a relatively flexible material, the partition being adapted to define a substantially fluid-tight low pressure area together with the wall surface and the housing or together with the wall surface alone; and means for discharging a fluid from the low pressure area. The partition has a portion extending outwardly from the position at which it is connected to the housing, and by a relatively small force, at least its free end can be displaced toward and away from the wall surface with respect to the housing. The free end is brought into contact substantially fluid-tight with the wall surface by the fluid pressure which acts on the partition owing to the difference in fluid pressure between the inside and outside of the low pressure area. The fluid pressure acting on the housing is transmitted to the wall surface through the wheels or endless tracks, thereby to cause the device to adhere to the wall surface.

A surface processing device comprising at least: a cylinder-shaped blast housing provided with the 1st opening and the 2nd opening; an annular vacuum seal which seals the gap between the blast housing and the object surface; a nozzle which injects surface processing substances toward the object surface; a parallel motion mechanism to make the nozzle be reciprocated in parallel along the object surface; a sheet belt for covering the 2nd opening; and a vacuum generating means for decompressing the space enclosed by the object surface, the blast housing, the vacuum seal and the sheet belt. Therein, a traveling means such as drive wheels is provided, the parallel motion mechanism to make the nozzle be reciprocated in parallel along the object surface in a direction that intersects with the traveling direction of the surface processing device, and the nozzle is also reciprocated in a direction that intersects with the direction in which the nozzle is reciprocated in parallel along the object surface.

The invention comprises a suction housing connected to a negative pressure forming means to suck in fluids, a suction opening member mounted on the suction housing, a part of which is caused to contact the surface of an object, and which defines a pressure-reduced area together with the suction housing and the surface of an object, and a means for maintaining the distance between the suction housing and the surface of an object at a predetermined distance, wherein the suction opening member and the surface of an object where in contact with each other are caused to be detached from each other partially or entirely due to the increase in the fluid pressure difference between the inside and the outside of the pressure-reduced area, resulting in the communication between the inside and the outside of the pressure-reduced area, allowing the outside fluid to flow into the pressure-reduced area.

A device capable of suction-adhering to a surface and moving therealong includes a pressure receiver, a partitioning device mounted on the pressure receiver and defining a pressure reduction space in cooperation with the pressure receiver and the surface, and a pressure reducing device for discharging a fluid from the pressure reduction space to decrease the pressure inside the pressure reduction space. The partitioning device includes a lip portion extending along the surface. A plurality of contacting devices are disposed at intervals at the part other than the outer peripheral edge portion in that opposing face of the lip portion of the partitioning device which is located opposite to the surface. The outer peripheral edge portion in the opposing face of the lip portion is brought into contact with the surface. At the same time, at the part other than the outer peripheral edge portion in the opposing face of the lip portion, the contacting devices are brought into contact with the surface. A gap communicating with the pressure reduction space is retained between the surface and the part other than the outer peripheral edge portion in the opposing face of the lip portion.

The device moves along the wall surface while suction-adhering thereto. The suction-adhering and moving unit includes a rotating member rotatably mounted on the supporting frame, and a sealing member for forming a pressure-reduction space in cooperation with the wall surface and the rotating member. The sealing member has an annular base portion fixed to the rotating member, a cylindrical main portion extending from the base portion in a direction away from the rotating member, and an annular contacting portion to be kept in contact with the wall surface. The suction-adhering and moving unit further includes a roller means rotatably supported on the supporting frame with its outer circumferential surface adapted to be pushed against the wall surface via the contacting surface of the sealing member, and a rotating driving source connected to either the rotating member and the roller means.
