An explosion-proof robot is an explosion-proof robot which is capable of self-propulsion on a field and includes: an explosion-proof casing of a hollow shape inside of which at least one electric component is placed; and a cover including a nonmetal material and covering at least part of an outer surface of the explosion-proof casing.

Explosion-proof robot

A clamper () includes a clamp mechanism () which inserts an insertion portion () into a tube member and clamps the tube member and a lifting and lowering mechanism () which lifts and lowers the clamp mechanism () in the insertion direction of the insertion portion (). The clamp mechanism () includes a clamp body () which has the insertion portion (), a cotter () which protrudes from the insertion portion () to come into friction-contact with the tube member and is movable in a reciprocating manner in the insertion direction of the insertion portion (), a piston rod () which presses the cotter () so that the cotter protrudes from the insertion portion () when being pulled toward the opposite side to the insertion direction of the insertion portion (), and a rod cylinder () which is integrated with the clamp body () and pulls the piston rod ().

Clamper and in-channel-head operation device

A water-chamber working apparatus according to the present invention includes a base that holds heat transfer tubes on a tube plate surface and is fixed to the tube plate surface, and a manipulator that is coupled with the base and is suspended in a water chamber. The base includes a base body that is coupled with a manipulator, a wing capable of being displaced forward and backward with respect to the base body, and clamper that are arranged on the wing and are inserted into the heat transfer tube to clamp and hold the heat transfer tube.

Water-chamber working apparatus and water-chamber working method

According to an installation method of a water-chamber working apparatus of the present invention, the water-chamber working apparatus includes a base that holds heat transfer tubes on a tube plate surface and is fixed to the tube plate surface, and a manipulator that is coupled with the base, suspended in a water chamber and arranged therein, and has a separable configuration. In this case, a base installing step of installing the base on the tube plate surface and a manipulator coupling step of carrying the separated manipulator (a front stage and a rear stage) into the water chamber sequentially and individually and coupling the manipulator with the base (a coupling link) are performed.
