The invention discloses a novel car roof structure comprising a car roof cover plate structure, a car roof rectifying structure and a car roof body structure. The car roof body structure, the car roofrectifying structure and the car roof cover plate structure are sequentially arranged on the top of a lift car from bottom to top. The section, in the horizontal direction, of the car roof rectifyingstructure is square. The car roof rectifying structure comprises an enhancing assembly arranged in the car roof rectifying structure, a front face plate, straight rectifying plates and bent arc rectifying plates, wherein the front face plate, the straight rectifying plates and the bent arc rectifying plates are arranged on the surface of the periphery of the car roof rectifying structure, and thefront face plate, one straight rectifying plate, one bent arc rectifying plate, one straight rectifying plate, one bent arc rectifying plate and one straight rectifying plate are sequentially arranged on the surface of the periphery of the car roof rectifying structure; and the bodies of each straight rectifying plate and each bent arc rectifying plate are in outwards-convex arc shapes, and therefore air flow on the flow guide surface of the top of the lift car can be guided out when the lift car operates at a high speed.
Description
technical field [0001] The invention relates to the technical field of fire elevators, in particular to a novel car top structure. Background technique [0002] Ultra-high-speed elevators will produce various noises during operation, such as the operation driven by the traction machine, the lifting and lowering of the car and counterweight, and the mutual friction between elevator components, and scientific research shows that the elevator in the running state Due to the large relative movement with the shaft wall, a certain wind pressure will be formed, and a large air resistance will be caused, so there will be a large "wind whistling sound". The cars in the prior art have adopted certain sound insulation measures, such as: thickening the car wall, adding sound-absorbing cotton or asphalt boards to the inner cavity of the wall plate, etc., to prevent this noise from being introduced into the elevator and affecting the passenger's riding experience and physical and mental ...
