A kind of Domestic Villa Lift's Well Layout and Car Frame Structure Design

With the increasing non-standard requirement in the current villa elevator market, especially the special shaft dimensions of low overhead and low pit, in order to meet the customized requirement of customers for elevators, here introduces a home villa elevator that can meet the overall requirements for villa elevators in GB/T21739-2008 Code for Manufacturing and Installation of Home Elevators. Combined with the shaft characteristics of the villa building and the existing elevator technology, the elevator shaft arrangement scheme is innovatively given to meet the requirements of the household elevator for the space of the car roof and the bottom pit for avoiding danger, and at the same time, the utilization rate of the shaft is improved. In the car structure design, the gantry structure is adopted with 2∶1 rope ratio, the under slung hidden suspension structure is designed, and the height of the subframe is lowered to meet low pit depth. Finally, the mechanical characteristics of the car frame under each working condition were analyzed by using the professional finite element analysis software ANSYS Workbench, which then determined the feasibility of the design scheme and verified the reasonableness of its structure.
