Detailed Description
The movable pulley block structure is suitable for a large-angle cable-stayed working condition gantry hoist and comprises two sets of movable pulleys, wherein the two sets of movable pulleys are concentrically and coaxially arranged and are jointly installed on a movable pulley beam, and an installation plate for installing the movable pulley beam is arranged at the upper end of the movable pulley beam.
In the embodiment, a hanging shaft is arranged in the movable pulley beam, the hanging shaft is positioned below the middle position of the two sets of movable pulleys, and the hanging shaft is arranged perpendicular to the mixed wheel shaft of the movable pulleys. Two ends of the hanging shaft penetrate through the mounting holes on the side walls of the two sides of the movable pulley beam and then are locked at the relative positions of the hanging shaft axial direction and the movable pulley beam through the clamping rings arranged in the clamping grooves on the hanging shaft, and the clamping rings are fixed on the movable pulley beam through bolts.
In the embodiment, a self-lubricating shaft sleeve is sleeved on the hanging shaft in the movable pulley beam, and a spacing sleeve is arranged between two ends of the self-lubricating shaft sleeve and the side wall of the movable pulley beam and sleeved on the hanging shaft. In this embodiment, be equipped with the piece of hanging on the self-lubricating axle sleeve, hang and connect the piece upper end through the self-lubricating axle sleeve can wind the pivoted installation of hanging on the movable pulley roof beam, hang and connect the piece lower extreme and be equipped with the pulley otic placode hole that can correspond with the gate otic placode on the gate otic placode after passing the movable pulley roof beam.
The hanging piece adopts the pulley lug plate of buckling into the type of falling U in this embodiment, and this lug plate upper portion is hung on self-lubricating axle sleeve, and pulley lug plate lower part system has the pulley lug plate hole that corresponds with the gate lug plate on the gate lug plate, and pulley lug plate and gate lug plate realize connecting through the axle device that moves that passes pulley lug plate hole and gate lug plate hole.
