Horizontal rotating mechanism suitable for net hanging rod different-position movable hinged support

Abstract

The invention provides a horizontal rotating mechanism suitable for a net hanging rod different-position movable hinged support. The horizontal rotating mechanism comprises a lantern ring, a lantern ring seat, a lantern ring seat cover body and a plurality of balls; the lantern ring seat is arranged on the lower part of the lantern ring, the lantern ring seat is limited in the lantern ring seat cover body, a through hole is formed in the upper part of the lantern ring seat cover body, and the connecting part of the lantern ring and the lantern ring seat penetrates out of the through hole; thelantern ring seat cover body is an annular cover formed by splicing at least two petal bodies, the periphery of the lantern ring seat cover body is connected with a left platform or a right platform,and the plurality of balls are further arranged between the lower side face of the lantern ring seat in the lantern ring seat cover body and the upper side face of the left platform or the right platform; the lantern ring is arranged on an external net hanging rod in a sleeving mode; and the tail end of the net hanging rod is detachably connected with an anti-disengaging end. According to the horizontal rotating mechanism, the butt joint requirements of angle deflection and axial sliding of the adjacent net hanging rods during construction operation can be met.

Description

technical field [0001] The invention relates to the field of building construction. Background technique [0002] In the construction process of high-rise buildings, a horizontal protective net for receiving falling objects must be added along a certain height outside the scaffolding. Usually the protective net is a large-mesh mesh body made of interlaced fiber ropes, and the surroundings of the large-mesh mesh body are connected with steel pipes and their accessories. [0003] Due to the high risk of setting up a horizontal protective net on the outside of the scaffolding, and according to the higher requirements for the enhanced protection of the falling object protection net, the ordinary large mesh mesh body must be replaced with a stronger falling object protection The weight of the falling object protection net itself and its erection area have increased accordingly, and the traditional protective net erection method is undoubtedly more dangerous. [0004] In order t...
