PURPOSE:To inspect peeling condition of a wall surface tile or the like efficiently by shoring up a support section with a sheave bearing a wire rope for electrically lifting a strinking section or the like to accomplish an automatic lifting of a detector along the wall surface of a building. CONSTITUTION:The height position of a weight section 8 is adjusted with a wire rope 16 applied on a traction sheave 13 responding to a motor 9 for winding up the weight section and a motor 11 for winding up the striking section while the lift of the striking section 4 is controlled. This rope 16 is born with free sheaves 3A and 3B provided separately vertical to a support section 1 shored up with a roof A-1. Then, the wall surface A-2 is striken by the striking section 4 electrically lifting between the support section 1 and the weight section 8 to detect an impact sound with a sound receiver. With such an arrangement, the detector is automatically lifted along the desired wall surface of a building to inspect peeling condition of a wall tile or the like. |
