FIELD: transport.SUBSTANCE: invention relates to industrial safety. Proposed cabin comprises the bed, carcass, life-supporting hardware, window and door openings and guards composed of acoustic panels. Said bed is installed at, at least, three pneumatic bumpers composed of rubber-cord shell whereto secured is cabin carcass composed by acoustic noise-absorbing panels shaped to parallelepiped composed by front and rear panel walls with noise absorber arranged there between. Every wall features U-like shape. Front wall has perforation. Front wall has glazing composed of noise-reflecting translucent polygonal panel. Said noise-reflecting translucent polygonal panel is composed by solid extruded polycarbonate plastic. Ceiling section is provided with illuminators. rear wall is located in the plane parallel with front wall plane. Side walls abutting on front wall are inclined thereto and glazed while those abutting on rear wall are perpendicular thereto. Sealed cabin is equipped with life supporting system composed by artificial microclimate system with control board. Noise absorber is composed of stiff and perforated walls with sound reflecting plies and sound absorbing materials plies arranged in two plies. Note here that sound-reflecting plies feature complex profile composed of uniformly distributed hollow tetrahedrons to allow reflection of sound waves falling in all directions which are arranged nearby stiff and perforated walls. Said plies are made of heat-insulating material to sustain preset micro climate in a room. Boards of mineral wool or glass wool with glass felt are used as noise absorbing material. Sound-translucent material is sued to line said sound absorbing material over its entire surface.EFFECT: higher efficiency of operator's work.8 dwg |
