Special lifting anti-falling machine for three-dimensional centered steel single-guide-rail and double-screw attached scaffold

Abstract

The invention relates to a special lifting anti-falling machine for a three-dimensional centered steel single-guide-rail and double-screw attached scaffold. The special lifting anti-falling machine for the three-dimensional centered steel single-guide-rail and double-screw attached scaffold comprises a three-dimensional deviation-rectifying and centering mounting interconnected wall-attached support device, a hot-rolled steel single guide rail and a double screw spiral lifting anti-falling device, wherein the hot-rolled steel single guide rail is provided with a deviation warning indicator; and the double screw spiral lifting anti-falling device is placed in the rail. Through the adoption of the three-dimensional deviation-rectifying and centering mounting interconnected wall-attached support device, position deviation of a wall bolt embedded pipe is overcome so that a plurality of supports mutually support the load of the scaffold to effectively prevent safety problems caused by bending of the guide rail and the structural deformation of the scaffold. As the guide rail is lifted by using a screw spiral transmission method, a screw spiral transmission self-locking function is adopted as a safety device, the double-screw spiral structure is concealed in the hot-rolled steel single guide rail and a nut slide way is made by using the inner wall of a profile steel, the special lifting anti-falling machine is beneficial for screw protection. The hot-rolled steel single guide rail with the deviation warning indicator is mounted to match the three-dimensional centering support; and cams at the bottom ends of screws control the screws in the same lifting unit to rotate one more circle after the screws in the same lifting unit both rotate for one circle so that the lifting height difference of the guide rail is controlled within a screw pitch.

Description

technical field [0001] The invention relates to the technical field of building construction machinery, in particular to a three-dimensional centering steel single guide rail double screw rod attached scaffolding special lifting and anti-falling machine. Background technique [0002] Scaffolding is an indispensable kind of machinery in construction engineering. With the development of the construction industry, many changes have taken place in scaffolding. At present, most of them are attached lifting scaffolding. Since the lifting mechanism of scaffolding needs to be attached to the wall, it is necessary to Bolts are installed on the wall, but because the bolts cannot be installed at the designated positions, it is difficult to install the track according to the requirements. If the installation position of the bolts deviates too much, it will make the installation of the lifting mechanism very difficult, and the track is easy to bend during use. , Major accidents are prone...
