Abstract

The invention provides an over-speed stop mechanism. The over-speed stop mechanism comprises a stop road wheel, a stop ejector pin, a stop beam and a stop road wheel drive device, wherein the stop road wheel drive device and the stop ejector pin are separately arranged at the two sides of the stop road wheel; while the stop road wheel drive device moves, the stop road wheel drive device can drivethe stop road wheel to rotate, and the stop road wheel can drive the stop ejector pin to rotate; while the stop road wheel drive device moves in a first direction and moves at constant speed in a second direction, the stop ejector pin does not limit rotation of the stop road wheel; and while the stop road wheel drive device moves at speed exceeding predetermined speed in the second direction, thestop ejector pin automatically returns to a locking state. The mechanism solves potential safety hazards due to the fact that spring rust and corrosion resistance is poor and elastic fatigue is liableto occur after use throughout the year, and avoids manpower resource waste caused by daily checking and replacing a spring. Compared with spring return, the over-speed stop mechanism improves triggersensitivity. Moreover, the over-speed stop mechanism is simple, firm and reliable in structure, is strong is rust and corrosion resistance, and greatly reduces a fault rate.

Description

technical field [0001] The invention relates to the technical field of lifting scaffolding, in particular to an overspeed stop mechanism and lifting scaffolding. Background technique [0002] The attached lifting scaffold is referred to as the climbing frame, which is mainly used in high-rise buildings. It can climb up or down along the building, and turn the suspended operation into the internal operation of the frame. It is not limited by the height of the building, saving manpower and materials. Great development advantage in high-rise buildings. [0003] The climbing frame is connected to the outer wall of the building through the wall-attached support, and the electric hoist is used as the power to climb up. The anti-drop device realizes the jamming protection function in the case of an accidental fall, and is an important safety device for the attached lifting scaffold. [0004] In the current climbing frame scheme, the anti-falling device adopts spring reset. Since ...
