Description

Technical Field

[0001] This utility model relates to the field of tower crane technology, specifically a quick-release loading and unloading frame for tower cranes. Background Technology

[0002] Currently, tower cranes are an important vertical transportation tool in modern construction projects, helping to build more and more high-rise buildings. However, due to the harsh operating environment and frequent use of lifting machinery, wear and tear can easily cause malfunctions. Once a malfunction occurs, it should be repaired immediately to avoid delaying the construction period and causing losses to customers. For tower cranes, the hoisting mechanism is also an essential part. As the most important of the four major mechanisms of a tower crane, the maintenance and repair of the hoisting mechanism after a malfunction has always been the most important issue for users.

[0003] Chinese Utility Model Patent Publication No. CN203728448U discloses a lightweight loading and unloading frame for tower cranes. This lightweight loading and unloading frame for tower cranes is easy and quick to install, can be folded or disassembled when not in use, occupies little space, and is convenient to transport. It can also be used in conjunction with the tower crane's lifting mechanism to disassemble and install the counterweight, saving the cost of hiring a crane and effectively improving production efficiency. However, although it can be used in conjunction with the tower crane's lifting mechanism to disassemble and install the counterweight, it is not convenient to quickly disassemble the entire loading and unloading frame or transport it at high altitudes. As a result, if the loading and unloading frame is damaged, it is not convenient to quickly replace individual parts, thus affecting its normal use and hindering its widespread adoption.

The advantage is that when the first main rod 2 and the second main rod 5 are connected, the connecting block 2 403 can be inserted into the rotating column 401. Then, through the design of the positioning bolt 402, the two can be locked. After that, with the connection flange, the first main rod 2 and the second main rod 5 can be fixed and can be quickly disassembled.

[0036] Specifically, a slot 6 is provided at the end of the second main rod 5 near the first main rod 2, and a limiting ring 7 is fixedly installed at the end of the second main rod 5 near the first main rod 2. The second main rod 5 is inserted into the second insert plate 901 through the slot 6. An insert plate 8 is fixedly installed at the end of the limiting ring 7 near the second main rod 5. A slot 902 is provided at the end of the second insert plate 901 near the first insert plate 8. The second insert plate 901 is adapted to the first insert plate 901 through the slot 902.
