Description

Technical Field

[0001] The utility model relates to the technical field of shaft protection, in particular to a multi-purpose elevator shaft protection device. Background Art

[0002] During the construction process, elevator shaft protection is the focus of safety protection at the construction site, and it is also a high-incidence location for safety accidents caused by falling from heights. In order to ensure the safety of construction during construction, guardrails are used at the construction site to surround the elevator door opening to prevent other personnel or debris from entering and causing injuries or causing injuries to others. Therefore, elevator shaft safety protection has become the top priority of safety work during the construction of high-rise buildings. There are various types of elevator shaft safety protection at various construction sites, but they all have different defects. It is mainly reflected in: First, the guardrail fixing device is installed on the front of the wall, and it is not suitable to be disassembled and assembled at any time, resulting in many items being dropped in the later process and more finishing work; second, the guardrail fixing device is installed on the side of the opening, and the later process needs to be repeatedly disassembled and installed, which is cumbersome to operate. Third, the mobile type is easy to cause protection loss by moving the elevator shaft safety guardrail at will during the construction process.
