Elevator hoistway steel frame offline pre-installation equipment and method

Abstract

The invention provides elevator hoistway steel frame offline pre-installation equipment and method. The elevator hoistway steel frame offline pre-installation equipment comprises a bracket fixing plate and a driving assembly. An elevator hoistway steel frame line is pre-installed in a factory in an offline mode, and only assembly is performed on site. According to a tool and the process method, the four surfaces of the elevator shaft steel frame are pre-installed, on-site construction time is greatly saved, generally, the one-week on-site construction cycle can be reduced to one or two days, the construction of the old community is arranged on working days, noise and resident disturbing can be greatly reduced, the personnel is prevented from concentrated in special periods, and the construction is carried out in a staggered mode.

Description

technical field [0001] The invention relates to the field of elevator equipment, in particular to an off-line pre-installation device and method for steel frames of an elevator shaft. Background technique [0002] With the development of society and the improvement of people's living standards, elevators have become an indispensable supporting facility for modern buildings. Especially in recent years, the country has vigorously developed infrastructure to improve the living experience of ordinary people, and some old communities have also begun to install elevators. During the elevator installation process, it is generally necessary to assemble the steel frame of the elevator shaft first, and then install the outer packaging and the elevator car. This process is very long and will generate a lot of noise, which will disturb the lives of ordinary people in old communities; on the other hand , due to some special reasons such as the epidemic period of infectious diseases, in ...

Problems solved by technology

During the elevator installation process, it is generally necessary to assemble the steel frame of the elevator shaft first, and then install the outer packaging and the elevator car. This process is very long and will generate a lot of noise, which will disturb the lives of ordinary people in old communities; on the other hand , due to some special reasons such as the epidemic period of infectious diseases, in order to reduce the concentration of personnel, many construction sites adopt the peak-staggered construction method, which cannot completely resume work, but the construction period cannot be delayed. Therefore, many construction units adopt an offline pre-installed equipment for elevator shaft steel frames and method, the steel frame of the elevator shaft is pre-assembled in the factory, and only assembled on site; but the elevator is generally installed in a building with at least 6 floors, even if multiple shaft steel frames are assembled, a single shaft The weight of the steel frame is several tons. When it is placed on the ground for outsourcing installation, only three sides can be installed at most, and the other side cannot be installed. Moreover, the general outer packaging includes glass and other products that cannot withstand heavy pressure. After installing the three sides, turn it over and install the bottom side, so this patent proposes an offline pre-installation equipment and method for the steel frame of the elevator shaft
