detailed description

The utility model will be described in further detail below in conjunction with the accompanying drawings, which is an explanation of the utility model rather than a limitation.

The utility model is a foldable indoor crane used for a node plate of a shock-absorbing component, which includes a detachable electric hoist 16, a foldable steel bracket and a tray 8 specially placed on the node plate. The crane is characterized by being foldable, easy to move, and saves storage space, and is designed with a structurally stable chassis 10 and various connection structures for stable and safe lifting. The surface of the tray 8 is smooth, which is beneficial for placing components such as gusset plates. Compared with the prior art, the utility model can better meet the actual demand for hoisting and installing the gusset plate of the indoor frame of a multi-high-rise building.

As shown in Figure 1 and Figure 2, the utility model uses two I-beams as the pole 6 to provide the vertical track, and the other two I-beams as the chassis 10 to provide stability, the pole 6 and the chassis 10 through the split pin 15 is hinged, and after the bracket is unfolded, the cotter pin shaft 15 is locked by the positioning bolt 13, so that the structure remains stable after unfolding, ensuring structural stability. The three connecting plates 7 are horizontally connected and fixed to the upright bar 6, preferably by welding. The tray 8 is connected to the vertical rod 6 through rolling bearings 9, and the two oblique rods 3 are connected to the cross bar 2 provided with the top pulley 1 through the fixed hinge 4, and are connected to the I-beam 10 at the bottom through pins 14.
