Description

Large modular unit lifting device

Technical Field

The utility model relates to a lifting device, in particular to a modular large-scale modular unit lifting device.

Background technique

The lifting of large modular units in high-rise building construction is limited by their size and tower cranes are often used for lifting.

During the construction process, there are safety risks when large modular units are traveling in the air. The risks mainly depend on the weight and size of the large modular units, the duration of vertical transportation, and wind and weather conditions. It is easy for the units to shake during vertical transportation due to excessive wind. When the vertical transportation space is narrow, shaking may easily cause damage to the large modular units, and safety hazards may also occur. Since tower cranes need to operate horizontal and vertical movements at the same time to realize the lifting operation of large modular units, this undoubtedly increases the difficulty of operation.

Furthermore, the top module frame is a trapezoidal frame structure, a first lifting mechanism connected to a lifting platform is provided at the top of the top module frame, and a second lifting mechanism connected to a workbench is provided at the top of the top module frame.

Furthermore, the modular frame is a rectangular frame structure, and first plug-in fixing parts are respectively provided at the four bottom corners of the modular frame, and plug-in holes compatible with the first plug-in fixing parts are provided at the four top corners of the modular frame, so that two adjacent modular frames can be inserted into the plug-in holes of the modular frame of the next layer through the first plug-in fixing parts of the modular frame of the upper layer, thereby realizing the connection between the upper and lower modular frames.

Furthermore, a pair of first latch plates are respectively provided on the outer periphery of the four bottom corners and the four top corners of the modular frame, and first pin hole sleeves are respectively provided on the first latch plates.
