Patent number: 11953317Abstract: A reference core position calculation device 100 that calculates a reference core position of an elevator shaft in which an elevator is to be installed includes a measurement unit 101 and a calculation unit 112. The measurement unit 101 measures a dimension of each portion of the elevator shaft. The calculation unit 112 calculates portion dimension values of the elevator shaft based on the reference core position and the dimension of each portion measured by the measurement unit 101. When the reference core position is a first reference core position, the calculation unit 112 determines whether portion dimension values of the elevator shaft calculated based on the first reference core position satisfy a predetermined specification.Type: GrantFiled: December 5, 2019Date of Patent: April 9, 2024Assignee: Hitachi Building Systems Co., Ltd.Inventors: Hirofumi Taguchi, Naoaki Noguchi, Daisuke Matsuka, Nobuaki Yagi, Masato Itou

Publication number: 20160116911Abstract: An assembly order generation device includes a radial/axial direction component detector which detects a component existing in a radial direction of a featured shape and a component existing in an axial direction of the component in a 3D CAD model. A directed graph expresses a connection precedence relationship in which the component is depicted by a node and a connection precedence relationship between the components which is depicted by a directed edge based on the detection result. A unit of disassembling and a disassembling order proposal based on the connection precedence relationship is generated, and an assembling order/direction/motion generation unit generates a disassemble direction based on the unit of disassembling and the disassembling order proposal and an assembly graph to generate a disassembling direction and a disassembling order, and reversely converts the generated disassembling direction and the generated disassembling order to derive an assembling order and an assembling direction.Type: ApplicationFiled: June 12, 2013Publication date: April 28, 2016Inventors: Noriaki YAMAMOTO, Hirofumi TAGUCHI, Atsuko ENOMOTO
