Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a cantilevered unloading platform. Background Art

[0002] At a building construction site, materials between floors are generally transported via tower cranes. The unloading platform is a transfer station for transferring materials from the lower floor to the upper floor. There are generally floor-mounted unloading platforms and cantilevered unloading platforms.

[0003] The traditional cantilever unloading platform uses welded channel steel or I-beam as the main beam (cantilever beam) and secondary beam, with pre-buried connectors on the main beam, connected to the building structure through steel wire ropes. Since the main beam needs to be connected to the U-shaped ring, the size of the pre-buried U-shaped ring is generally larger than the main beam. If the U-shaped ring spacing is too large during docking installation, it will be unstable during the installation process, and wooden squares must be used to fill the gaps after adjusting the level; if the U-shaped ring spacing is too small, it will be difficult to align during the hoisting docking process, affecting the assembly efficiency. Utility Model Content

A guide piece is arranged on a U-shaped ring to guide the main beam to be installed, and the main beam is initially limited by a first arm and a second arm to reduce shaking. After the entire platform is adjusted to be stable, wooden blocks are inserted into the inside of the guide piece to lock it.

[0005] The technical solution of the utility model is a cantilever unloading platform, comprising a cargo box, a bottom beam, a plurality of sets of U-shaped rings pre-buried in the layer to be installed, and a plurality of fulcrums pre-buried in the layer above the layer to be installed;

[0009] Preferably, a limiter is provided at the bottom of the main beam for abutting against the layer to be installed, so as to limit the distance that the bottom beam extends into the building.

[0010] Preferably, the total length of the bottom beam does not exceed 6m, and the length of the portion extending into the building is not less than 2m.

[0011] Preferably, multiple steel wire ropes are symmetrically arranged along both sides of the cargo box; the angle between the steel wire rope and the main beam is 45-60°.

[0012] Preferably, at least three rope clamps are provided after the wire rope is fixed to the lifting eye and the fulcrum.

[0017] Preferably, the guide member comprises a first arm and a second arm; one end of the first arm is connected to the rotating shaft, and the other end is connected to the second arm, and forms an angle of no more than 30° with the second arm;

[0018] When the main beam enters the U-shaped ring, it first contacts the second arm on the guide member; the entire guide member rotates around the rotating axis and gradually compresses the angle between the first arm and the second arm until the second arm is completely in contact with the main beam and remains parallel to the ground of the building.
