The connection of narration wire rope below, the medial head of wire rope ties up on the hole of hoisting mechanism cover plate, and the head at its two ends respectively ties up on the pin-and-hole of pin in the clamping pin mechanism by fixed pulley.
In normal condition, the plane contacts on the cover plate of hoisting mechanism and the spring base, the pin of clamping pin mechanism is blocked by pressing plate by the compression spring, lifting arm disconnects or the last lower chuck of hydraulic jack self is malfunctioning when taking place, lifting arm in the hoisting mechanism is up and to drive cover plate up under the spring action in compression, cover plate affects on the wire rope and draws, and the pin in the clamping pin mechanism at dial-out wire rope two, under the effect of compression spring, load is axially outer to be stretched out, and its end reaches in the grid on the canopy batten, because bar batten is fixed on the scaffold, promote track and be fixed on the floor face, institute so that whole hydraulic pressure lift scaffold be suspended in the air, under the unlikely bob.
The utility model has the advantages that: use a kind of building operations hydraulic pressure lift of the utility model scaffold safety dropping prevent mechanism, when lifting arm disconnect or hydraulic jack self dop is malfunctioning up and down the time, whole hydraulic pressure lift scaffold can not avoid personal injury and equipment to damage from falling in the air.
