Technical Field
This application claims priority from U.S. provisional patent application No.62/712,666 entitled line coupling for elevators, filed 2018, 7, 31, the entire contents of which are incorporated herein by reference.
Background
The articles and methods described below relate generally to a wire coupler for supporting a compensating cable below an elevator car.
Elevators typically include compensating chains, cables or ropes that provide balance for the weight of the suspended components. One example of a conventional elevator assembly is shown in fig. 1 and is shown to include an elevator car 10 and a
Another example of a conventional elevator assembly is shown in fig. 2 and is shown as including an
PCT patent application No. wo 2002/084018A describes a safety line in two embodiments. According to the first embodiment, in addition to the main ropes (3, 5, 6, 9-12), there are one or more auxiliary ropes (2, 7, 13) having a greater coefficient of tension. When the ropes (1, 4, 8) break, these ropes (2, 7, 13) break eventually and in this way jerks (jerk) and impacts, which may be caused by the broken ends of the main ropes (3, 5, 6, 9-12), are prevented. The auxiliary ropes may be interlaced with the main ropes in a number of different ways. According to another embodiment, the double loop (14) (manufactured from main ropes (15), the main ropes (15) are bent into a loop (16, 17) at the ends, longer and thinner auxiliary ropes (18) parallel to the main ropes (15) are interlaced by knots (19), the auxiliary ropes (18) will eventually break when the main ropes (15) are overloaded and break and in this way smooth the impact that may cause accidents.
Us patent No.8,544,912B1 describes a lift cable sleeve assembly comprising a centering collar element, a centering housing element, a cable and a lift support, wherein the centering collar element forms a concentric sleeve around a central recess. The centering case element is defined by concentric flange members that form concentric sleeves around the centering case element. The wire is inserted into the central recess and the centering collar element is swaged to the wire. The centering collar element, the centering housing element and the centering collar member are integrated into a continuous non-welded assembly to maintain rigidity of the wire rope within the centering collar member. The lifting support is a mechanically supported lifting device.
German utility model DE 202015004045U 1 describes a stop element with a shell, characterized in that the stop element (3) located in a frame structure (1) is detachably fixed, that a protective sheath (2) is arranged concentrically to the axis (12) at least partly in the longitudinal direction of the axis (12) of the stop element (3), that the protective shell (2) is movable at least in the longitudinal direction (10) of the axis (12) of the stop element (3), that the frame structure is positioned to be arranged concentrically, and that the protective shell (2) is arranged concentrically to the axis (12), to an inner cladding (7) and to another located in the inner cladding (7), forming an outer cladding (8).
Us patent No.6,990,761B1 describes that after making a rope sling, the sleeve is painted and dried and an adhesive type label containing all the information required for ASME b30.9c is applied directly to the surface of the sleeve. The sleeve and label are then encapsulated using a clear shell, coating or sealant. This will protect the tag from corrosion and environmental influences and will ensure a permanent and legible tag.
