AB - The elevator drive host is installed in the machine room, and the car and counterweight are installed in the hoistway. The  lift car and counterweight are suspended on the traction wheel of the driving host through suspension devices such as steel  wire rope. Therefore, it is necessary to make an opening on the ground of the machine room in order to pass the suspension  device through. In order to prevent small parts or maintenance tools from falling into the well from the ground opening,  resulting in casualties, the safety technical specification for special equipment stipulates that the opening on the ground of the machine room shall be as small as possible, and the opening above the well must adopt a ring frame, which shall  protrude from the ground for at least 50mm. At present, elevator construction units basically use concrete materials to  build concrete ring frames around ground openings. Although not many concrete materials are required, special preparation  shall be made. In addition, it will take several days for the frame to dry after masonry, which will affect the construction  progress. In order to solve the above technical problems, this paper provides an adjustable device for the ground opening  of elevator machine room, which has rapid installation and strong adaptability.
