Three-dimensional centered steel single guide rail double screw rod attached scaffolding special lifting anti-fall machine

Abstract

The invention relates to a three-dimensional alignment steel single guide rail double-screw-attached scaffold special lifting and anti-falling machine, which includes a three-dimensional deviation correction centering installation interconnected wall support device, a hot-rolled steel single guide rail with a deflection warning device and a rail inner The double-screw helical lifting anti-drop device has three parts, and the three-dimensional deviation correction centering installation is interconnected with the wall support device to overcome the position deviation of the pre-embedded pipe of the wall-through bolt, so that multiple supports can jointly support the scaffold load, effectively preventing the bending of the guide rail and Safety problems caused by the deformation of the scaffold structure; the guide rail is lifted by the screw screw transmission method, and the self-locking function of the screw screw drive is used as a safety device. The double screw screw structure is concealed in the hot-rolled section steel single guide rail, and the nut is made of the inner wall of the section steel The slideway is beneficial to the protection of the screw rod; the single guide rail of hot-rolled steel with a deflection warning device is installed with the three-dimensional centering support; the cam at the bottom of the screw rod controls the screw rods in the same lifting unit to rotate once before they can rotate one more time. The height difference of the guide rail is controlled within one 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, scaffolding has undergone many changes. At present, most of the commonly used is attached lifting scaffolding. Since the lifting mechanism of scaffolding needs to be attached to the wall, it must be installed on the wall. Bolts are installed on the body, but because the bolts cannot be installed at the specified 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. A major...
