Abstract
The invention discloses an upper beam structure of an elevator car frame, which comprises an upper beam, two rope wheel assemblies and a connecting beam, wherein the upper beam is horizontally arranged; the connecting beam is horizontally arranged on the upper beam and is not parallel with the upper beam; both ends of the connecting beam extend out of the upper beam; rope wheel shaft seat plates are both fixed on both end parts of the connecting beam; rope wheel shafts of the two rope wheel assemblies are horizontally arranged on the rope wheel shaft seat plates respectively; the rope wheel bottom of each rope wheel assembly is lower than the lower surface of the upper beam; and the rope wheel top of each rope wheel assembly is higher than the upper surface of the upper beam. Accordingly, the upper beam and the rope wheel assemblies are superposed on the vertical projecting surface, the height of the upper beam structure can be reduced, and thus the height of a top layer of an elevator well can be reduced to save the cost of construction. An included angle between a rope wheel central connecting line of the two rope wheel assemblies and a central connecting line of the car guide rails at the left side and the right side in the horizontal projecting surface is larger than 0 degree but not large than 90 degrees, and thus the distribution of the two rope wheel assemblies is flexible, a wrap angle of an elevator can be increased, and the application range of the elevator is expanded.
