Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a safety protection device. Background Art

[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. In the existing technology, the installation of elevators is completed in the elevator shaft. The elevator shaft is a hoistway where the elevator is installed. The size of the hoistway is determined according to the elevator selection. Elevator tracks and counterweight tracks are installed on the shaft wall, and elevator doors are installed in reserved door openings. There is an elevator machine room on the top of the hoistway. The elevator shaft involves the technical field of building construction. A new type of outer mold, inner mold and through-wall bolts is used. The inner mold consists of an inner mold, a rotating angle mold group, a horizontal telescopic top rod group, a chassis, a chassis leg, and a vertical adjuster group at the bottom of the inner mold. The outer mold and the inner mold use a back hook to assemble multiple pieces of shaped combined steel molds, and are connected into shape by through-wall bolts.

[0003] However, the general safety measure for installing elevators is to build a construction platform in the elevator shaft. If the fixing quality of this construction platform is not up to standard, it is very likely to cause workers to fall from the elevator shaft and cause accidents. Although the elevator construction safety protection platforms currently used in the market can bear loads stably, there is no way to protect the workers who are still on the construction platform when an accident occurs.
