Abstract

The invention discloses a magnetorheological type anti-falling and anti-toppling device of lifting scaffold The two ends of the device are connected with a building wall and a lifting stand column of the lifting scaffold respectively, and the device comprises an anti-falling module, an anti-toppling module and a base; one end of the base is fixed to the building wall, and the other end of the base is connected with the lifting stand column through the anti-falling module and the anti-toppling module; the anti-falling module comprises an anti-falling support, a stepped shaft, a gear, a rack, control coils, magnetorheological fluid and end covers, and the gear is fixedly connected to the stepped shaft in a sleeving mode and meshed with the rack which is fixed to the lifting stand column; the stepped shaft is movably sleeved with the anti-falling support, the two ends of the stepped shaft both extend out of the anti-falling support and are provided with the control coils respectively; the end covers cover the control coils and are fixedly connected with the anti-falling support, and the magnetorheological fluid is stored in the confined spaces formed between the end covers and the anti-falling support. According to the device, the magnetorheological fluid characteristics and the compact structure are utilized, the anti-falling performance and anti-toppling performance of the lifting scaffold are achieved simultaneously, the adjustment and installation are facilitated, and the reliability is high.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a magneto-rheological type anti-fall and anti-tilt device for a lifting scaffold. Background technique [0002] Magnetorheological fluid is a controllable fluid, which is a suspension formed by mixing tiny soft magnetic particles with high magnetic permeability and low magnetic hysteresis and non-magnetic liquid. This kind of suspension exhibits low-viscosity Newtonian fluid characteristics under the condition of zero magnetic field; while under the action of strong magnetic field, it presents high-viscosity, low-fluidity Binghan fluid characteristics. Moreover, the rheology of magnetorheological fluid under the action of a magnetic field is instantaneous and reversible, and its shear yield strength after rheology has a stable corresponding relationship with the strength of the magnetic field. It has been used in shock absorption, braking and other devices . [0003] Attach...
