Problems solved by technology

The force-bearing form of the 360°rotating roof crane requires a large ring gear, tower top and balance arm, and some even require more and heavier counterweights to resist the overturning moment, resulting in the The components are all heavy or the number of components is large, and the structure is complex, bulky, and heavy. This is not in line with the design principle that the roof hanging components should be small and light. Inconvenient for vertical transportation

Abstract

The invention discloses a mast type roof hanger for dismantling an internal climbing type tower crane. The mast type roof hanger comprises a base, a mast mechanism, a luffing mechanism, a cargo boom,a rotating mechanism and a jack mechanism. The small and light design principle is adopted, the mast mechanism is used for replacing a balance arm and a balance weight of a traditional roof hanger, and the luffing mechanism adopts a fixed pulley block and a movable pulley block to enable lifting of the cargo boom saves more labor. The mast type roof hanger has the beneficial effects that single component is short and light, the overall machine is simple in structure, low in weight, reasonable in stress, convenient to mantle and dismantle, convenient to transport vertically, and capable of reducing the construction cost and improving working efficiency.

Description

technical field [0001] The invention relates to a construction equipment in the technical field of high-rise or super high-rise building construction, in particular to a mast type roof crane used for dismantling an internal climbing type tower crane. Background technique [0002] Internal climbing tower cranes or internal climbing external tower cranes (hereinafter referred to as internal climbing cranes) are commonly used lifting equipment for high-rise or super high-rise buildings. After the building is capped, roof cranes are generally used for demolition. The existing roof cranes mainly have specifications of 16t, 8t, 4t, etc., and the appropriate roof crane is selected according to the maximum weight of a single component of the internal climbing crane to be removed. The demolition process is usually to use a large roof crane to dismantle the inner climbing crane first, then use a small roof crane to dismantle the large roof crane, and finally the small roof crane to di...
