Safety protection device for preventing personnel from falling

Abstract

The invention relates to the technical field of building construction, and discloses a safety protection device for preventing personnel from falling. Comprising a base arranged at a construction site hole pile opening, an axially-through inlet is formed in the base, a conveying component capable of stretching into the inlet is arranged at the top of the base, a lifting table for adjusting the height of the base is arranged on the base, and a plurality of electric telescopic rods are arranged at the bottom of the lifting table. The bottom of the base is rotationally provided with a plurality of protection cylinders through rolling bearings, the protection cylinders are sequentially connected from top to bottom, and the multiple protection cylinders are provided with construction windows. According to the protection device, the lifting table and the base on the lifting table are lifted through the electric telescopic rod so as to adapt to the uneven ground of a construction site, and personnel and rockfall are prevented from falling into an entrance. When concrete needs to be smeared on the hole wall, the protection plate is opened for construction, then the protection barrel is rotated on the rolling bearing, full-angle concrete smearing on the hole wall is achieved, and therefore the situation that wall surface soil and smeared concrete are loosened and fall off, the safety of workers is threatened, and the construction progress is affected can be avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a safety protection device for preventing people from falling. Background technique [0002] In the construction site, when the hole pile drilling machine cannot enter in some special cases, the hole pile can only be excavated layer by layer manually from top to bottom, and then the excavated soil is transported to the ground. Usually, the hole of the hole pile should be set with a lock, and the hole wall of the hole pile should be poured with a concrete wall to prevent the hole wall from collapsing to ensure construction safety. During the construction process, due to the existence of a certain construction period, some construction sites have adopted protective measures such as well meshes to prevent people from falling, but the well meshes are easy to loosen, and the protection effect is poor; at the same time, due to the uneven ground of the construction site, t...
