WIPO Patent Application WO/2021/184815
Kind Code:
A1
Abstract:
An elevator guide rail fixing device, comprising: guide rail pressuring plates (110), comprising first pressuring arm portions (110a) used for pressing and fixing a guide rail (10) of an elevator onto a guide rail holder (20) of the elevator; and bolt connecting components (130, 140, 150), used for fixing the guide rail pressuring plates (110) onto the guide rail holder (20), and further comprising reinforcing pressuring plates (120), fixed by the bolt connecting components (130, 140, 150) onto the guide rail pressuring plates (110), and comprising a second pressuring arm portion (120a). An opening (111) used for accommodating the second pressuring arm portion (120a) is formed on the first pressuring arm portions (110a); when the guide rail pressuring plates (110) are in a seismic working condition that the guide rail pressuring plates (110) are deformed due to an earthquake impact, the first pressuring arm portions (110a) of the guide rail pressuring plates (110) and the second pressuring arm portion (120a) of the reinforcing pressuring plates (120) press and fix the guide rail (10) together. The elevator guide rail fixing device is suitable for both a seismic condition and a non-seismic condition, which improves the universality of the elevator guide rail fixing device.
